    Technical area
    The present invention relates to a continuous material treatment system, comprising a product inlet tube to be treated, a material treatment mill and a flexible containment enclosure. It also relates to a corresponding process for treating material in continuous flow using such a system.
    State of the art
    The patent application EP 041 2004 proposes an enclosure for handling products or objects containing toxic or radioactive elements, of the glove box type, the manipulation of objects being done by an operator placed outside the enclosure and through gloves and rounds of gloves. The enclosure provides a hole for evacuation of objects by gravity in a receptacle. A grinder is fixed opposite the evacuation hole to grind the products handled in the enclosure and transform them into waste in the form of small pieces to reduce the volume required for storage. This system does not include an upstream / downstream disconnection system connected to a mill for accessing it in in-line mode.
    The document FR 2 855 994 relates to a device for isolating a contaminated intervention medium. It comprises a box of containment glove box type. This enclosure comprises an open surface intended to come into contact with and to be closed by a surface to be treated with an object. The system allows, by providing a closure of the enclosure by a portion of the surface of the object to be treated itself, to avoid having to isolate the entire object or, alternatively, to have to completely surround a section of this object.
    EP 0 689 904 discloses a glove box having a bottom and side portions and upper parts, which form a sealed internal volume gas-tight. The bottom is provided with product receiving devices, which include a gas-tight sealable passage, the product receiving devices being disposed along a circle or an arc of a circle, concentrically with respect to the product. the axis of rotation of the bottom and maintaining the product or semi-finished product to be machined, so that the partial zone of the product or semi-finished product to be machined under a protective gas atmosphere communicates with the internal volume of the box; glove, and is accessible to machining devices mounted inside the glove box. At the same time, another partial area of the same product or semi-finished product is disposed outside the inner volume of the glove box or is available for machining by tools mounted outside the box glove.
    WO 08 152 415 discloses a containment apparatus which comprises an access device for providing access in a closed environment to a sealed enclosure. A container and a passive port create the sealed enclosure, which contains a contaminated material. During normal use of the speaker, the access device is stored separately from the speaker. As such, the speaker can function normally with guards, etc. in place as required. When access to the enclosure is required, the access device is anchored to the passive port. Once anchored, an active port of the access device cooperates with the passive port to open an access opening in the enclosure. An operator can then enter the enclosure by inserting the hand into a hand protector and passing through the access opening. The hand protector is sealed around the periphery of the active port. As such, the operator remains isolated from the enclosure. When access is no longer required, the operator may remove the hand protector from the access opening and close the access opening. Accordingly, the access device may be transported and stored for reuse, or cleaned, or anchored to another enclosure for transferring materials, etc.
    The document FR 2 872 446 discloses a double-door sealed transfer device comprising actuators for doors equipped with portholes. The double-door sealed transfer device ensures a sealed transfer between a first sealed enclosure, for example a containment cell and a second sealed enclosure, for example a transfer box. It comprises two doors each equipped with locking means for locking it on a flange having a central opening and an actuating member for actuating the locking means. These actuators are rotatably mounted in the doors and have a porthole.
    [0007] Document EP 1 225 012 describes a confinement assembly comprising a powder handling booth of sufficient size to admit an operator. The containment assembly includes a curtain type barrier barrier adapted to allow an operator in the powder handling booth outside the treatment area to operate within the treatment area.
    None of these documents describes an architecture for feeding a continuous flow mill placed in a protected flexible containment enclosure while allowing to switch easily and quickly to a mode without flow, to perform an intervention in the enclosure , from outside of it.
    In general, in known systems for treating a material such as a powdery substance, solid, sludge, solids-laden liquids, or the like, intended for the manufacture of a pharmaceutical, chemical, food or cosmetic product. other, the elements used to convey the powder are directly connected to the mill. Thus, in case of blockage or congestion of a sieve, or to ensure cleaning for a change of material, or for any other reason, intervention at the mill requires first of all to separate the two elements ( inlet and mill), lift the intake tube to release the inlet port of the mill, and finally provide an enclosure ensuring that the intervention can be performed in a protected environment. Such interventions are relatively tedious to perform, require a significant completion time. In addition, the stages of disassembly and reassembly of the milling tube are often difficult to implement in a protected enclosure, in particular because the volume of the enclosure must be able to adapt to the movements of the connected elements. and disconnected.
    To overcome these disadvantages, the invention provides different technical means.
    Brief summary of the invention
    Firstly, a first object of the invention is to provide a continuous flow treatment system or method, in particular of powdery, granular, sludge or solids-laden materials for use in continuous flow mode. .
    Another object of the invention is to provide a system or method of treatment, to simplify the steps of intervention in case of obstruction, cleaning or sieve change.
    To this end, the invention provides a continuous material flow treatment system, comprising:a product inlet tube to be treated;a movable tube adapted to receive the product from the inlet tube;a mill of treatment;wherein the movable tube is disposed between the product inlet tube to be treated and the treatment mill, said tube being movable between at least two positions, comprising:a product flow position, wherein the tube hermetically connects the product inlet tube to be treated to the treatment mill; andan intervention position, wherein moving the movable tube releases internal access to the treatment mill;the movable tube being disposed in a flexible containment enclosure provided with at least one access glove box type.
    With the system according to the invention, the architecture of the elements is particularly simple, with advantageous manufacturing costs, and the transition from one phase to another of the operational modes is carried out quickly, with simple manipulations .
    According to an advantageous embodiment, the movable tube is pivotally mounted so as to ensure its movement between the fluid flow and intervention positions by pivoting.
    Alternatively, the movable tube is movably mounted in translation so as to ensure its movement between the fluid flow and intervention positions by a translational movement.
    Advantageously, the grinding treatment system is disposed in a substantially sealed chamber of the external environment provided with at least one glove box type access.
    The invention also provides a process for treating material in continuous flow, according to two modes, in the treatment system,wherein, in product flow mode, the material from the product inlet tube to be treated flows to the mill through the movable tube to convey the material to the mill for processing by the latter;in the intervention mode, the flow of material from the product inlet tube is interrupted, the movable tube is moved to release internal access to the mill (preferably from above the mill), at least one element or an area of the mill undergoes an intervention in order in particular to ensure the resumption of the product flow mode, said intervention being performed under an atmosphere protected by the protective enclosure, and using at least one box gloves of the enclosure.

    Alternatively, the displacement of the movable tube between the product flow and intervention positions is effected by a translational movement.
    Brief description of the figures
    Examples of implementation of the invention are indicated in the description illustrated by the appended figures in which:<tb> Fig. 1 <SEP> is a perspective view of an exemplary embodiment of a treatment system according to the invention;<tb> figs. 2A and 2B <SEP> illustrate the system of FIG. 1, without the protective enclosure, to lighten the illustration; in particular, FIG. 2A shows the system in material flow mode and FIG. 2B shows the system in intervention mode;<tb> figs. 3A and 3B <SEP> illustrate the system of FIG. 1, only with the frame of the protective enclosure; in particular, FIG. 3A shows the system in material flow mode and FIG. 3B shows the system in intervention mode.
    Example (s) of embodiment of the invention
    FIG. 1 illustrates an exemplary embodiment of the invention, in a perspective view, where a functional assembly is integrated in a containment enclosure, or protection, 6, substantially sealed to the external environment, for performing manual interventions when that proves necessary. Fig. 2A, described later in this document, is a similar view, without the protective enclosure, to facilitate visualization of the functional assembly. The containment enclosure is flexible, that is to say that it comprises flexible walls allowing easy deformation of the wall when manipulated by an operator. The flexible wall may comprise a film, or sheet, thin of at least one polymer, preferably transparent so as to allow viewing from outside the enclosure 6, which is inside the enclosure. For example, the flexible film can be made of PVC, polyethylene, neoprene, etc.
    The enclosure 6 of protection makes it possible to dispose the functional assembly of a treatment system 1 of powdery, granular, sludge, solids laden, or other materials, in a closed and protected environment so that the process of treatment can be performed under specifically controlled conditions. In the example illustrated in FIG. 1, the enclosure 6 of flexible confinement is delimited by a frame of enclosure 11 whose dimensions are adapted according to the volume required to house the functional assembly of the treatment system 1. The dimensions are also advantageously defined so as to take account the intervention operations to be performed. It is also useful to find the right balance between a volume large enough to leave the operator comfort and ease of work, and a sufficiently small volume allowing the same operator to be close enough to the elements he must handle. A small volume also facilitates the establishment and maintenance of a controlled atmosphere. The pressure in the chamber 6 may correspond to the atmospheric pressure or be lower than it (negative pressure) or even higher (positive pressure), as required. A drive and control system of a mill 4 is indicated by number 15.
    As illustrated in FIG. 1, the enclosure 6 has openings at the locations corresponding to the intervention tubes 7. These tubes serve as passages for the forearms of the operator during the manipulations to be performed. The tubes are tightly closed outside the intervention ranges. To keep the atmosphere under control, the intervention tubes 7 are provided with sealed devices with gloves for the user. Such devices are well known and are therefore not illustrated in order to maintain a better readability of FIG. 1.
    In the exemplary embodiment illustrated, the enclosure also has openings for the access tubes 14 providing access to products in and out of the system- as well as tools.
    Fig. 3 2A shows the elements disposed inside the enclosure 6. A product inlet tube 2 to be treated allows the product to be received in the system. Upstream, the product to be treated is advantageously conveyed by a set of specifically adapted piping or simply by supply from containers or bags of product. The inlet tube is preferably in the up position relative to the other elements to promote the flow of the product. At the base of the treatment system, for example near or on the ground, a mill 4 is arranged in axial alignment with the inlet tube 2. Between these two elements axially spaced from one another, a movable tube 3 is arranged. The mill may be a mill for grinding, crushing, mixing, deagglomerating, weighing, sorting, granulometry or any other mill or system for treating powdery, granular, sludge or solids laden materials, etc.
    When it is arranged as illustrated in FIG. 2A, the movable tube 3 ensures fluid communication between the inlet tube 2 and the upper portion of the mill 4. The treatment system is then in "product flow" mode. According to this mode, the mobile tube 3 acts as an intermediate link between the inlet tube 2 and the mill 4 to ensure the product flow. The adapter 8 at the base of the inlet tube facilitates the connection with the movable tube 3. The plate 9, surrounding the periphery of the top of the mill, makes it possible to recover the product likely to flow during the process and / or when disconnecting the movable tube 3. In addition, the plate 9 may also have a work table function.
    When the movable tube is arranged as illustrated in FIG. 2B, the treatment system is then in "intervention" mode. In this mode, the movable tube 3 is moved so as to release an internal access 5 to the mill 4. In the illustrated example, the displacement of the tube is ensured by pivoting about an axis substantially parallel to the axis A-A of the treatment system 1. In a variant, the tube 3 is mounted to move in translation. According to yet another variant, the tube 3 pivots about an axis substantially perpendicular to the axis A-A of the treatment system. The "intervention" mode is used when an intervention must be performed at the mill 4, for example to clean an obstructed screen, or to prepare a material change without risk of pollution between the old and the new material.
    Figs. 3A and 3B illustrate the treatment system described above, according to the two respective modes, of "product flow" on the one hand, and "intervention" on the other hand. These figures show that the frame 11 of the chamber 6 is dimensioned so as to move the movable tube 3 between its two end positions. In fig. 3B, it is observed that the space or volume of work 20 or intervention allows, in addition to performing the movements of the movable tube 3, to perform interventions on the treatment system with an ergonomic and functional arrangement . We also observe in fig. 1 that the intervention tubes 7 are substantially aligned axially and radially with respect to the movable tube 3 so as to give a substantially direct access to the latter and to the internal access 5 to the mill when the movable tube 3 is positioned in the operating mode. 'intervention.
    PROCESSING PROCESS
    The previously described treatment system is advantageously used in the context of a material treatment process, in particular a powdery material, with steps involving mechanical operations performed on the material, such as, for example, grinding operations, deagglomeration, crushing, weighing, sorting, granulometry, or other mechanical operation. The process is particularly suitable for powdery materials, without excluding other forms of materials, for example granular, sludge or solid-laden liquids.
    In "product flow" mode, the method provides a substantially continuous flow of the material in the inlet tube 2 to the movable tube 3 to the mill 4, where the material is treated. According to an exemplary embodiment, the powdery material comes into contact with a sieve positioned at the inlet of the mill 4. During the flow of the material through the sieve orifices, some particles will gradually cause areas or surfaces where the The flow is retarded either by particles of larger volume, or agglomerates of particles or clusters of particles partially or completely blocking sieve orifices. The material flow is then disturbed and the flow decreases, sometimes strongly. It is then necessary to carry out an intervention to eliminate the obstruction zones and / or to clean the screen. In addition, the need for access to the internal parts is required for the tool change and / or inspection, for example allowing an operator to visually inspect the tooling at each batch change, in order to detect an abnormality.
    To perform such an intervention, the operator uses the intervention tubes 7 to have access to the work volume 20 without affecting the controlled atmosphere. The operator moves the movable tube 3 from the "product flow" position to the "intervention" position. He then has free access to the entrance of the mill. The operations can then be performed. These operations concern, for example, the unblocking or cleaning of a sieve, a configuration change, or other. To facilitate the cleaning operations, an inlet 12 and an outlet 13 of liquids are provided. The inlet 12 and the outlet 13 of liquids can also be used for cleaning the enclosure 6 itself. For example, the cleaning liquid, which may be water, is introduced by the liquid inlet 12 in order to be sprayed on the inner walls of the enclosure 6, and discharged through the liquid outlet 13.
    When the various steps of the intervention are performed, the operator repositions the movable tube 3 in "material flow" mode. The nature of the intervention steps, their order and number may vary from case to case. Moreover, some, see all the steps can be automated.
    The treatment system of the invention therefore allows use in continuous flow mode, that is to say to achieve a continuous material treatment process, without the need to disassemble one or parts system and / or replenish the system with the material to be processed. It will be noted, however, that the treatment system of the invention nevertheless makes it possible to treat the batch material if this is desired. Thanks to the treatment system previously described, the tedious steps of disassembly of the previous systems, as well as the steps of reassembly, are removed. Furthermore, the arrangement of the inlet tube 2 relative to the mill 4 is fixed, which greatly simplifies the architecture of the elements and the intervention phases, with significant cost savings.
    The figures and their descriptions made above illustrate the invention rather than limit it. In particular, the invention and its various variants have just been described in connection with a particular example comprising a functional unit.
    Nevertheless, it is obvious to a person skilled in the art that the invention can be extended to other embodiments in which, in variants, two or more functional assemblies are provided in the same enclosure.
    The reference signs in the claims are not limiting in nature. The verbs "understand" and "include" do not exclude the presence of elements other than those listed in the claims.
