    FIELD OF THE INVENTION - The invention relates to a screen and a screen module for a screen. BACKGROUND OF THE INVENTION A screen separating material has a screen table, i.e. a screening level. Screening table - includes shaft assemblies that rotate screening elements, such as round or angular discs or sacred stars, through which material is screened. - The number of shaft assemblies can vary, = depending on the operating capacity, for example. Successive shaft assemblies are positioned so that their screening elements overlap. The shaft assembly - screening elements are selected according to the material to be processed. The motor rotates one or more shaft assemblies and the rotational motion can be transmitted to other shaft assemblies. Screening openings are formed between the screening elements of successive shaft assemblies. Pieces larger than the screening openings remain on top of the screening table and rotate - the screening elements carry the pieces, for example to a conveyor after the screening table. Pieces smaller in size than the screening openings fall from the screening openings of the screening table under the screening table, for example into a funnel or conveyor. The portion of the piece size larger than the screen openings is called the oversize, and the portion of the smaller piece size is called the undersize. Screen structure - designed for a specific material and / or piece size, on the basis of which e.g. = wheelbases and disc sizes are determined. Typically, a particular standard piece size is screened from a particular standard material by a particular N standard process.
    S = Brief summary of the invention I 30 N It is an object of the invention to provide a screen module and a modular screen, the 2 screen tables of which consist of separate screen modules. Screen modules facilitate 3-screen maintenance, upkeep and cleaning. In addition, the screen modules are N interchangeable.
    A screen according to one aspect of the invention includes a body and one or more screen modules that are detachable from the screen body, attachable to the screen body, and / or replaceable.
    A screen module according to one aspect of the invention is attachable to the screen. The screen module may include at least one positioning element by means of which the screen module can be inserted into the screen.
    —Description of the Drawings In the following, the invention will be described with reference to the accompanying drawings, in which Figure 1 shows a screen according to an embodiment of the invention from above.

    N - Figure 1 shows a screen according to an embodiment of the invention from above. The screen table consists of separate screen modules 1001, 1002, 1003, 1004.
    Each screen module 1001, 1002, 1003, 1004 includes shaft assemblies 102. The shaft assemblies 102 have screening elements 101 disposed on the shafts. The shaft assemblies 102 are transverse to the longitudinal axis of the screen. The shaft assemblies 102 are rotatable relative to the axis of rotation of the shaft. The screen modules 1001, 1002, 1003, 1004 include successive shaft assemblies 102 positioned so that the screening elements 101 of the successive shaft assemblies 102 overlap. The screening elements 101 in one shaft assembly 102 and in one screen module 1001, 1002, 1003, 1004 are similar to each other so that - the screening result of the module is similar throughout the screening module. The shaft assemblies 102 are arranged in succession in the longitudinal direction of the screen so that screening openings 103 remain between the screening elements 101 of the successive shaft assemblies 102. The number of shaft assemblies 102 depends on the shaft spacing. The wheelbase affects the piece size of the material to be screened together with the machine speed and the size of the screening elements 101. The screening elements 101 may be discs or stars spaced at regular intervals on the shaft assembly 102. The shaft assemblies 102 are mounted at the shaft ends from bearing surfaces to allow rotational movement of the shaft. The bearings may be supported on the screen module body. The bearings can be, for example, flanged bearings or thrust bearings, for example, depending on the type of screen module body. The screening element 101 may consist of two opposing castings. In addition to the screen elements 101, the shaft may have sleeves, spacers or other parts with which it is possible to act e.g. for clearance adjustment and = edge tightness of the screen module.
    N S The material to be screened is directed to the screen. The rotational movement of the screening elements 101 S allows the material to pass on the screen table I 30 at the same time as the pieces N smaller than the screening openings 103 are screened under the screen table, where they are collected, for example, in a hopper or 3 conveyor. In Figure 1, the material to be screened is first directed to a first screen module 1001. The screen modules 1001, 1002, 1003, 1004 may differ in screen elements 101, in size and / or spacing with respect to the shaft assembly 102, and / or distance between the shaft assemblies 102. For example, the first screen module 1001 may include smaller screen openings 103 than at least one of the following screen modules 1002, 1003, 1004, which allows fine material to be screened by the first screen module 1001.
    The screen can have different screen sizes and sizes. Screen modules are designed and manufactured for a particular material and / or piece size to be processed. One screen module can perform one material and / or piece size process. By replacing the screen modules, the screen can be quickly configured for different materials and / or piece sizes.
    In Figure 1, two adjacent screen modules are used with one motor. The shaft assemblies 102 of the first two screen modules 1001, 1002 are rotated by a first motor 300. The shafts of the latter two screen modules 1003, 1004 are rotated by a second motor 300. - Alternatively, there may be one motor for each module or one for the entire screen table. One or more motors 300 are attached to the screen body. The one or more motors 300 may be a hydraulic motor or an electric motor. The motor (s) 300 are located on one longitudinal edge of the screen. This edge can be called the use side of the screen. The screen can be serviced and adjusted - from the opposite side, which can be called the treatment side of the screen. Figure 2 shows a screen according to an embodiment. In Figure 2, three screen modules 1001, 1002, 1004 are attached to the screen body 200 and one module 1003 is detached from the body 200. Each of the screen modules is removable and replaceable. When the screen module is removed, the motor 300 and = its transmission to one or more axle assemblies are removed, after which the screen module N can be removed from the frame 200, for example by means of fork tines S. In this way, a single screen module can be removed from the screen, for example for maintenance S. The screen module can also be replaced with another I 30 screen module. In this way, the screen can be converted for different uses. N The number, size and type of shaft assemblies and discs can be selected according to 3, what and what kind of raw material is screened. The piece size 3 of the material is affected by the rotational speed of the shaft assemblies, as well as the dimensioning of the shaft assemblies N and the discs. Dimensioning affects the size of the screening openings and - the speed of rotation - affects = the behavior of the material, - for example mixing. The piece size of the material, in turn, affects the use properties and further use of the screened material. Figure 2 shows four screen modules 1001, 1002, 1003, 1004. The number of screen modules can vary and can be, for example, 1-6. Multiple screen modules allow separate parts, i.e. screen modules, to be removed, serviced, adjusted or replaced separately. In this way, maintenance, adjustment and other maintenance work can be performed separately from the screen. In this way, there is more space, which enables e.g. safer use of various devices. It is possible - to change the sieve module to another or to replace two or more sieve modules with one. For example, in Figure 2, the middle modules 1002, 1003, or all of the screen modules may be replaced with a single screen module. Alternatively, one screen module may be replaced and replaced by two or more screen modules. If a spare module is used - in place of one or more removed screen modules, it can be installed in place of the removed screen. This allows the screen to be used without having to stand for maintenance. In known screen constructions, the detachable unit may be a shaft assembly with screening elements. For example, if the discs as a screening element need to be replaced, their shaft assembly (s) must be removed from the screen body, after which the discs can be replaced. Removing and reattaching the shaft assembly is laborious and time consuming. In addition, several maintenance and installation work must be carried out on a sieve table, where - there is little working space and it is not safe to work. In addition, the use of the sieve = must be stopped during maintenance.
    N S Figure 3 shows a screen module according to an embodiment of the invention. S The screen module 1003 has - as screening elements - discs = 101 I 30 - in the shaft assembly. The shaft assemblies are arranged in succession so that the discs 101 of the N consecutive shaft assemblies overlap. 3 The shaft assemblies are attached to the walls 111 or edge portion of the screen module. 3 Opposite walls 111 may be similar on the maintenance and operation side. N The wall of the screen module of Figure 3 consists of an upper edge 1112, a lower edge 1113 - and a connecting side edge 1111. The upper edge 1112 and the lower edge 1113 may be substantially horizontal and may be connected by a substantially vertical side edge 1111. The lower wall edge 1113 can be positioned against the screen body. the positioning elements abut the wall positioning elements 106. The wall 111 of the screen module, its lower part 1113, has positioning elements 106 which can be placed on or against the counterparts of the screen body. The screen module 1003 can be placed in the screen body, in place relative to the body, by means of positioning elements 106. The screen body has corresponding positioning elements which form mating pairs with the positioning elements 106 of the screen module.
    Figure 4 shows screen modules according to an embodiment of the invention. The screen modules 1003, 1004 are attached to the screen body. In Figure 4, the screen modules 1003, 1004 are positioned in the body 200 by means of the body positioning elements 201, into which the screen module positioning elements are positioned, forming counterparts to the body positioning elements 201.
    —Screen modules have a drive element 104 at the end of each shaft assembly, such as a two-row sprocket. The drive elements 104 are rotatably connected to each other 105, for example by a belt or chain. The drive element 104 of Fig. 4 may be a sprocket, a pulley, a gear wheel or the like, with which the rotational movement can be transmitted to a single shaft. Alternatively - each shaft may have its own drive motor, e.g. an electric motor or a hydraulic motor, and for example a clutch for power transmission.
    In Figure 4, two adjacent screen modules 1003, 1004 are driven by a motor
    300. The drive wheel of the motor 300 is connected to the adjacent drive elements 104-7, 104-1 by adjacent screen modules 1003, 1004. = In the last shaft assembly of the module 1003, the drive element 104-7 and in the first shaft assembly of the N screen module 1004, the drive element 104-S1, which are placed side by side, are connected to the drive wheel S of the motor 300 by means of a transmission 1051. The transmission 1051 may be a chain or a similar element transmitting the rotational movement I 30. Thus, two N adjacent sieve modules 1003, 1004 can be used with one motor 300. Correspondingly, several sieve modules with shaft assemblies 3 rotatably connected to each other can be used with one motor 3.
    N - There may be one motor 300 per two screen modules, the torque of which is transmitted to successive shaft assemblies of adjacent screen modules. The motor 300 can drive or rotate the outermost axis of the module from which the rotational motion is transmitted - by means of a transmission 105, for example belts, gears or transmission chains, to other shaft assemblies of the screen module.
    In Figure 4, the motor 300 is attached to adjacent, outermost shafts of two successive screen modules from which power is transmitted to the other shafts of the screen modules.
    The motor 300 and the motor transmission 1051 may be detachable, for example by a quick release.
    The motor transmission 1051 is removed before the screen module 1003, 1004 is removed from the body 200. The same or different screen module can be replaced in the body, after which the motor transmission 1051 can be inserted into the structure.
    The type and size of the screen module may vary.
    If the two screen modules 1003, 1004 are replaced by one screen module, the motor 300 may be omitted or not used if - the replacement single screen module is driven by another motor of the body 200.
    The second motor of the body 200 may use one or more screen modules as needed.
    The body 200 has positioning elements 201 by means of which the screen modules can be - placed and / or held in place relative to the body.
    The positioning elements 201 of the body 200 are arranged to abut the positioning elements 106 of the screen module. The positioning elements 106 of the screen modules form counterparts to the body positioning elements 201. The screen module may be secured to the body by the screen module and the body positioning elements.
    The positioning elements 106 of the screen modules may = be openings, recesses, protrusions or shaped parts such that they N form a counterpart to the positioning elements 201 of the body 201, which may be protrusions, recesses or shaped parts.
    The screen body 200 is of a predetermined size S.
    The frame has one or more motors 300 and x 30 positioning elements 201 for positioning the modules. & In Fig. 4, the body positioning element 201 comprises two cross-shaped plate-like parts 3 which taper upwards.
    The positioning elements 106 N of the screen module include openings, the edges of which abut against the cross-sections and the body of the positioning element 201.
    Thus, the screen module snaps into place, the lower part of the side wall against the body 200, and remains in place against the body 200. The crosswise positioning element 201 can prevent the movement of the screen module in the longitudinal and transverse direction of the screen. The upwardly tapering positioning elements 201 can facilitate their insertion through mating openings in the screen module as positioning elements 106. Thus, the positioning elements 201 may be arranged to guide the screen module into place in the body 200. Alternatively, the body 200 may have openings and the screen module may have positioning elements that fit into the openings in the body 200. Alternatively, both the body 200 and the screen module may have positioning elements that abut each other. The locating elements may be welded to the body 200 and / or to the screen module. The positioning elements may be mating pieces, openings, pins, holes, shocks or similar parts or elements. For example, the positioning element may be an opening in the body and in its counterpart a pin-like part of a screen module; or vice versa. The openings can also form positioning elements to be aligned with each other. The edges of the openings may have a protrusion, protrusion or shape to align and / or position the openings against each other. The positioning elements can hold the screen module, or part of the wall against its body, in place relative to the body both in the longitudinal direction of the body and in the transverse direction of the body. The positioning elements can be used to attach the screen module to the frame. The positioning elements may include an opening into which - the fastening means can be inserted. With the fastening means, the screen module can be fastened to the frame. The fastening means may be a screw, a bolt or a similar mechanical fastening means. Additionally or alternatively, the attachment of the screen module to the screen body can be done by means of an edge of the body which can be raised and lowered against the screen module. The screen module can be locked in place relative to the body by means of positioning elements. The screen module can be pressed and = locked in place by the edge of the screen, such as the side edge. The edge of the sieve and the edge of the N sieve module are designed to be compatible.
    SS In Fig. 4, the drive elements at the axle ends may be sprockets I 30 104. The sprockets 104 are double-rowed and connected to each other such that the inner wheel of N double-row sprocket 104 is connected to the inner wheel of its adjacent 2 sprockets by a chain and the outer wheel of sprocket 104 is connected to 3 to the outer wheel of the sprocket with a chain 105. The inner and outer wheels of the sprocket N 104 are attached to wheels adjacent to different sides of the sprocket 104, for example, the inner wheel of the previous and the outer wheel of the next part of the next sprocket. Thus, the shaft assemblies of the screen module are rotatably connected to each other and the driving force can be transmitted between the shaft assemblies.
    Rotating a single-axis assembly transmits rotational motion to the associated shaft assemblies.
    Instead of double-row sprockets, single-row sprockets can be used.
    The sprockets can be rotatably connected to each other, for example with a single chain.
    Each screen module can have its own use or each shaft assembly can be used separately.
    The axle assembly-specific motor allows the axle assembly to be used on its own.
    The centralized chain drive shown in Figure 4 has a simpler and cheaper implementation than axle assembly-specific motors.
    Instead of a chain, belt or similar transmission connecting the wheels, the axle assemblies can be rotatably connected to each other by means of the toothing of the wheels at their ends and the gears.
    Shaft assemblies may be arranged to be belt driven or chain driven.
    When one motor is arranged - to use several axle assemblies, traction can be carried out on belts and wheels; chains and sprockets; or by means of gears.
    The two-row wheels allow all the shaft assemblies of one screen module to be connected to each other, for example by means of chains or belts.
    When the screen module, the shaft assemblies of which are connected to each other, is placed - in the screen, the use of all the shaft assemblies of the screen module is achieved by connecting one sprocket to the drive motor to transmit power.
    This simplifies and speeds up screening module replacement, maintenance, and screen configuration.
    Figure 5 shows a side view of a screen according to an embodiment of the invention. = The screen modules 1001, 1002, 1003, 1004 are placed in the frame 200 by means of the body positioning elements 201 and their counterparts, the positioning elements of the screen modules S.
    The motors 300 and their transmission 1051 are mounted S in place to drive the screen modules.
    One motor 300 drives I 30 - two adjacent screen modules 1001 and 1002; 1003 and 1004, the force N is transmitted from the motor 300 to the outermost drive wheels 104-1, 104-7 of the adjacent screen modules by means of a transmission 1051. > N The screen 203 must be opened in the screen. In Figure 5, the device 203 to be opened is open or - in its upper position.
    The opening edge 203 may be a longitudinal edge or a side edge of the screen.
    The side surface of the edge 203 may be arranged to maintain a position substantially perpendicular to the plane of the screen table. The side surface of the side 203 may be slidable in the up-down direction; for example, without tilting the side surface. The upper and / or lower edge of the vertical edge 203 may be movable directly in the up-down direction. When raising / lowering, the edge 203 can remain in its vertical position with respect to the horizontal plane of the screen. To handle the screen modules and motors 300, such as removing and attaching, the body edge 203 is raised. The side 203 can be raised to the upper position and lowered to the lower position by means of lifting cylinders 204 on the side edges of the side edge 203. The lifting cylinders 204 may be - for example hydraulic cylinders or alternatively, for example, spindle motors or the like, for example based on the driving force of the machine, such as the use of electricity or hydraulics. When the flange 203 is raised to its upper position, as in Figure 5, the screen drive head motors 300, selections, and the chain assembly of the shaft assemblies are accessed. - This is also possible - it is possible to remove, remove, install, insert and fasten the screen modules. Once the edge 203 is raised, some or all of the screen modules can be removed by disconnecting the screen module drive to the drive motor 300. The motor 300 may have a quick release mechanism that allows the motor 300 transmission, such as a belt or chain, to be loosened and further removed from the screen module wheels.
    Once the screen modules are positioned in the frame by the guide elements 201 and their counterparts, and the motors 300 and their transmission are secured in place to drive the screen modules, the body edge 203 can be lowered to the down position. In the lower position, the insert 203 protects the parts of the drive head, such as the sprockets at the ends of the axle assemblies, the motors, the transmissions and the N guide elements. In addition, in the lower position, the insert 203 forms the edges S on the screen table. By means of the side edge 203, the screen modules can be pressed against the body S, attached to the body, whereby they remain in place in the height direction of the screen.
    x 30 Tata is shown in more detail in the following Figure 6. & Figure 6 shows a screen module placed in the frame according to an embodiment 3 of the invention. The wall 111 of the screen module may be C-shaped. N The upper part 1112 and the lower part 1113 of the wall 111, which may be — horizontal, are connected by a side part 1111 to which the shaft assemblies 102 are attached, for example by means of bearings. The drive elements 104 of the shaft assemblies 102 are on the opposite side of the wall 111 from the screening elements.
    The drive elements 104 are connected to each other by means of a transmission 105.
    The lower edge 1113 of the wall 111 of the screen module is placed against the body 200, or the edge portion of the body, by means of the positioning elements 201 of the body and the mating elements of the screen module.
    The lower edge 1113 of the wall is held in place by the positioning elements 201 and their counterparts.
    The edge 203 of the body is lowered to enclose the drive side of the screen, such as the drive elements 104 of the screen module, their transmission 105, the positioning elements 201, and one or more motors.
    The side edge 203 forms the outermost part of the screen - the operating side, as shown in Fig. 6. A similar arrangement including the edge of the screen which can be opened vertically, i.e. rising and falling, can also be on the treatment side of the screen.
    The side panel 203 is arranged to secure the screen module in place, against the body 200.
    The sideboard 203 is arranged to press the screen module against the screen body 200. The sideboard 203 is the length of the longitudinal side of the screen or its body.
    The sidewall 203 extends from the outer edge of the screen against the top 1112 of the screen module wall 111 and may extend to the side portion 1111 of the wall 111, as shown in Figure 6. The side portion 203 against the top 1112 of the wall 111 may press the screen module down against the body 11.
    This allows the side panel 203 to hold the screen module in place.
    A portion of the sidewall 203 against the top 1112 of the wall 111 may be shaped or may have an element 205. An element 205, which may thus be a separate or integral sidewall portion 203, may be described below. The element 205 - is located between the sidewall 203 and the top 1112 of the screen module wall 111. = The element 205 can extend to the N sides adjacent to the upper part 1112 of the wall 111 of the screen module.
    Element 205 may be in the form of a downwardly opening C or U.
    S The element 205 has a base part and S side parts extending substantially perpendicularly therefrom.
    The side portions of the element 205 border the wall module 111 I 30 - the upper portion 1112, positioned on one or both sides thereof.
    The side portions of the element 205 N may have beveled edges against the corner, side and / or edge portions 3 adjacent to the upper portion 1112 of the wall 111.
    The shape of the element 205 corresponds to the shape of the wall 111, or the upper part 1112, and the adjacent corner N, the corner, the side and / or the edge of the upper part N of the sieve module 3.
    The element 205 can fit tightly - against the upper part 1112 of the wall 111 of the screen element, and against the adjacent corner, side and / or edge thereof.
    The shape of the element 205 may correspond to the shape of the wall 111 facing it. Element 205 allows the screen module to be locked against the body 200. The rotating shaft assemblies 102, their bearings, and the motor (s) cause mechanical stress when the screen is operated. Attaching the screen modules and keeping them in place allows the screen modules to be used in the screen. The screen modules can be attached to the body 200 from the lower part 1113 of the wall 111 by means of positioning elements and their counterparts. The attachment from the upper part 1112 of the wall 111 can be arranged by means of a side edge 203, and possibly its element 205. The element 205 may be made of steel, such as a cut steel plate. The shape of the element 205 may affect the functionality. For example, a downwardly opening C- or U-shaped element 205 may assist in aligning and positioning the edge 203 against the top 1112 of the wall 111.
    - The opening edge allows one or more screen modules to be locked in place. When the edge is closed, it forms an edge / edge on the screen table, keeping the screenable material passing through the screen table on the screen table or preventing the material from falling to the side. In addition, the openable guard protects bearings, sprockets and / or other components required for the use of axle assemblies.
    The frame structure of a screen with screen modules allows the screen modules to be replaced. The interchangeability of the screen modules facilitates maintenance, upkeep and cleaning. The removal of the screen modules is quick and detachable - the screen modules can be delivered for maintenance, for example, to a workshop where there is = more space and better maintenance capabilities. The interchangeability N of the sieve modules makes it possible to change the size of the sieve piece and to maximize the operation time of the sieve. S The screen module can be serviced without downtime. In the screen, another screen module can be used on the farm during maintenance. The cost of the sieve module I 30 is only a fraction of the total cost of the sieve, and downtime, such as maintenance, repair, and N cleaning times, erodes performance. Thus, keeping additional screen modules O in reserve is cost effective.
    > N The frame structure of the screen module may consist of one or more parts or subassemblies. For example, the screen module may consist of two side plates that allow positioning and locking on a drop-down edge. Alternatively, the structure may include a welded structure that allows the material to fall through the screen table during screening and that is locked to the screen body, e.g., with screws. The frame structure of the screen module is compatible with the structure of the screen body. This allows the screen module to be positioned and the screen module to remain in place during screen operation. The frame structure of the screen module allows for quick and easy positioning and locking of the screen to the screen body during use, for example by means of positioning elements and possible fastening elements. - Screen module - frame structure = allows - screen modules - to be moved, positioned and handled with fork tines, such as a forklift or wheel loader. The frame structure of the screen module may allow handling by a crane or similar transfer device.
    The body according to the embodiments may have a different number of different - screen modules. The screen modules are interchangeable and their number in the body can be varied. The length of the sieve table affects the screening result. If a longer sieve table is desired, the length of the body, the number of sieve modules and / or the length of the sieve modules can be changed.
    - The screen modules according to the embodiments allow them to be removed and replaced with a new or different screen module. The separate screen modules can be quickly and easily removed from the frame and attached to the frame. With replaceable screen modules, the purpose and / or application of the screen can be changed, for example according to the size of the piece of material to be processed. The screen modules are separate parts from the screen body. They = can be placed on the frame by means of N positioning elements in the frame and in the screening modules. The control elements of the body and the screen module can form counterparts. The positioning elements can fasten the S screen module against the lower edge of the wall against the screen body in the longitudinal and transverse directions of the body. In this way, the movement of the screen module in the longitudinal and transverse direction N of the body can be prevented. The screen modules can be locked in place by means of the side edges 3 of the screen, which in their lower position press the screen modules against the screen body 3. The shafts of the sieve modules are operated by motors attached to the frame, N which may be hydraulic motors. From the motors, power can be transmitted to the screen modules, or to their shafts, for example via chains.
    The ends of the shaft assemblies may have two rows of sprockets, allowing the chains connecting them to pass from each axle assembly to the next. One motor can use one, two or more screen modules. The motor (s) and the transmission of the motor (s) to the shafts are detachable. This allows the screen module to be removed and / or replaced.
    Individual removal of the screen modules facilitates screen maintenance, service and / or cleaning. A spare module can be installed in place of the removed screen module, so that the screen can be used during maintenance and / or cleaning. As the quality of the material to be screened or the desired piece size changes, the screen can be upgraded as needed by replacing one or more screen modules with one or more different screen modules. For example, the sizing of screening elements and shaft assemblies can be changed. All sieve modules in the screen can be similar. Alternatively, for example, the first screen module may have smaller screen openings. Thus, as a result of the screening - three fractions are obtained instead of two: in addition to the excess and the undercut, the so-called fines. Embodiments of the invention have been described above. It is possible to make different implementations within the framework of an inventive idea. The above parts can be modified, replaced, or omitted to produce and attach a corresponding screen module to the screen body. oO O OF
