    The invention relates to equipment for grinding rubber waste and can be used, in particular, for grinding rubber tires.
    A device for crushing rubber waste is known, comprising a pressure chamber with fluidization openings and a piston CO placed in the chamber for movement in the axial direction.
    In the known device, the holes for liquefaction are made in the chamber in the direction coinciding with the axis of the piston, i.e. at the base of the chamber. Such an embodiment of the holes necessitates the creation of a pressure, the bursting of rubber I, considerably exceeding the critical pressure, at which, at the corresponding diameter of the hole, a cold liquefaction of rubber occurs. This is due to the fact that the piston has to overcome internal friction, depending on the type of material to be comminuted. Therefore, the actual pressure of the pool is determined from the pressure to overcome internal friction and critical pressure. A disadvantage of the known device is that its structure
    provides for the ability to reduce the pressure of internal friction, which leads to increased energy consumption and the need for 5 created1 and more pressure.
    The purpose of the invention is to reduce energy consumption for grinding waste and the required pressure.
    The goal is achieved by the fact that, in the first variant, a device for grinding rubber waste contains a pressure chamber: with openings of the fluidization chamber and placed in the chamber with the possibility of an axial piston in the axial 15 direction, openings
    performed in a transverse direction to the piston axis
    In addition, the piston is made with a cavity and holes in the base. 20 The chamber is placed on a disputable element with a central hole, coaxial; 1. With the pressure chamber, and the piston has a shoulder; forming a moving cutting edge in contact25 with the upper edge of the central opening forming a fixed cutting brim,
    The device is equipped with a d-tank fitting device into the pressure chamber. In order to reduce the energy consumption for grinding and the required pressure in the device for grinding rubber waste, the pressure of Lenin with the holes for grinding and pressing tools can be made, the latter can be made at least from drums mounted rotatably against the positive sides and about the formation of an open pressure chamber, the openings for liquefaction being made in the shell of the radiators in the radial direction. Moreover, the outer side surfaces of both drums can be made with profile teeth that engage with each other, and the holes for liquefaction are made in the hollows and coq | with the cavity of the drums. FIG. 1-4 shows a device with a piston, a longitudinal section, (various stages of operation) 5 in fig. 5 - 10 - the same, with a device for inserting a tire into the pressure chamber; in fig. 1119 - the same, when processing a torus-like right-milled tire; Fig 2022 - the same, when grinding waste in the form of scrap; 23-24, the same with holes in the piston; in fig. 25-26 is a variant of the device with a tool for pushing in the form of drums; in fig. 27 is a longitudinal section of the device in which the drums are provided with protrusions. In FIG. A device is shown consisting of an architrave of a press and a support 2. The architect of a press is rigidly connected with a rod 3 of a working cylinder of 4 double action. The device has a pressure chamber 5 (Fig. 3), in the walls .6 of which an opening 8 8 is made transverse to the axis of the piston 7. The cavity of the pressure chamber 5 is formed by the space between the inner surface of the wall 6 and the piston 7, upon further lowering the press 1 architrave 1 pressure 5 is bounded above KaNH-i shoulder 9 architrave 1, and from below by end surface 10 of support element 11. Support element 11 is mounted on support 2. On its end surface 10 there is a slot 12, on which pressure chamber 5 is supported. The bore hole 13 is coaxial with the pressure chamber 5, in which the piston 7 of the press 1 of the press can move tightly with a small gap 1i4. In the support element 11 there is an internal cylindrical space 14 connected to the hole 13. The diameter of the shoulders 9 of the press architect 1 is chosen so that they can move along the inner side surface of the wall 6 of the pressure chamber 5 with a small gap. Holes 8 are conical holes drilled in the radial direction, extending towards the side surface of wall 6 and having a base diameter of 5 mm. In the upper part of the pressure chamber 5 there is a conical inlet 15. On the outer surface of the pressure chamber 5, stiffening ribs 16 are welded on (FIG. 4). The piston 7 has shoulders 17 and goes down to a smaller diameter piston 18. The upper edge 19 of the central opening 13 and the edge 20 of the shoulder 17 form, respectively, fixed and movable cutting edges interacting with each other. The device (Fig, 1-4) works as follows. Pockets 21 are placed coaxially on the conical input 15 of the frame. Then the piston 7 is lowered under the action of the cylinder 4 to the position as in FIG. 1. In this case, the piston 18 passes through the opening of the clamp 21, and the shoulders 17 come into contact with the top side 22 of the tire 21. As the tire beads are made of steel and the frame it is rigidly connected with them, then, under the action of the shoulders 17 of the piston 7, it is pinched by the flanges 22 into the cavity of the pressure chamber 5 (Fig. 2). After pokryshka 21 completely retracted into the cavity of the pressure chamber 5, the cutting edges 19 and 20 cut off both sides of the 22 cables, which slide down from the piston 18 downwards (Fig. 3). Upon further movement of the piston 7 down in the pressure chamber 5, the pressure necessary for cold rubber liquefaction is created, and under the action of this pressure the rubber begins to flow and press through the openings 8 in a ground state. The magnitude of the fluidizing pressure required depends on the diameter and number of holes 8, as well as on the cross section of the chamber of pressure 5 and the nature of the rubber waste being crushed. In this case, its value is 25,000 N / cm2. 5 After grinding the rubber waste, the piston 7 is raised to its initial position by means of the working cylinder 4. FIGS. 5-10 depict a chopping device with an attachment 23 for retracting the cuttings 24 into the pressure chamber 5. This device consists of four levers 25 with paws located in the radial grooves of the piston 18 of the architrave 1 and capable of tilting: in a vertical plane around the bolts 26. Moving levers 25 with dogs outwards is limited by an inclined plane 27 notches 28o. On the inner side, levers 25 with dogs interact with a clamping cone 29, which is located in the central hole of the piston 18 with the possibility of axially. The clamping cone 29 is coupled to the actuator in this case with the rod 30 of the hydraulic working cylinder 31 of double action. As shown in FIG. 5, the cylinder 31 of the worker and the livdre are inside the piston 7 of the press architrave 1, and the rod 30 slides into one. 1. The coax C1-alto hole 32 is 7 of the architrave. 1, Worker; DSC 31 soycine-and with RSChTOCH of pressure head asl (not shown) "Device for grinding - rubbing rubber waste with a device for entering. | -ROOK; Ik into the pressure chamber p.

B), the position of the piston 1 g – rj – iari – 25 with dogs is seized on the back side of the 22 pugs 2 – t and npF – i movement of the architravt press down and the last pressure 5 ( Fig. 6) In this position, the levers 25 with dogs are set up with the aid of a cone 29, which is in the extreme swivel position, and the clamping cone 29 is raised with the help of a working center 31 (Fig. 7), With the further movement of the press 1 of the press, the levers 25 with the dogs rest against the face 10 on the surface 10 and as a result turn Nutri (FIGS. 7 and 8) about 1 pg Arch grass-ECCA then moves downward. During this movement, the process of measuring & Holes 8 are also used for forcing rubber mass with a diameter of 5 mm. The pressure in the pressure chamber is 5 20000 N / cm. The ground rubber 11 drops off the plates 33 located at an angle (Fig. 8). After the press architrave 1 rises to the upper initial position, the clamping cone 29 is again lowered to the extreme position (5). At the same time, from the pressure chamber 5, through the exhaust box 3, the calcerized residue 35 containing the staple layers of the cover 24 is removed. The outlet bush 34 is located with the possibility of moving both the inner side surface of the wall 6, as well as inside the central opening 36 in the support element 11 and is connected to the stem 37 of the hydraulic working double-acting cylinder 38 (FIGS. 8, 10). : 5 B1, that the bottom pressure chamber 5 pressure surface 10 is formed by the upper surface of the exhaust box 34. The working cylinder 33 is also connected to a source of pressure oil (not shown). In FIG. 1i-19, an alternative device with a piston in which The pressure foam chamber is installed with the possibility of: movement. The device in this case is equipped with vertical guide columns, and the pressure chamber housing 5 is connected to the stem-39 of the hydraulic operating cylinder 40 of double action. At the same time, the side of the surface of the stacked samer is fixed; l, avlenk lk 5 movable relatively rigidly fixed supporting tube 41. In the case of a broken case, the upper surface of the supporting tube 41 forms an end face 10 (FIG. 16); Restricting the pressure chamber 5 on the bottom. In the cavity of the pipe 41, there is an arrangement 42 for inserting the tire 24 into the chamber 5. In this device there is a head 43; P-Bi-DKuaH in axial and ;; actions (FIG. 11). The head 43 is connected with the lever w with the spacing of the D-: b, ggprotp-p-warding of the bolts 47 and spring-loaded in the gripping position. Arms, 48, the shifting of the levers with the pawl - ™ 46 is carried out using a truncated cone 49 made on the lower end of the piston architrave t. The grinding device (FIG. 1119) operates as follows. To shred the tire 24, the pressure chamber 5 is lowered to its lowest position using the working cylinder 71 pa 40 and the press with the help of the working cylinder 4 (Fig. 11) is raised to the uppermost position. Then, the straddle pad 24 is placed between the press architect 1 and the pressure chamber 5. After the press architect 1 is lowered (as shown in Fig. 12), the head 43 of the insertion device 42 rises to the extreme position with the help of a cylinder 45 (Fig. . 13). In this case, the levers with the dogs 46 are moved apart with the help of a truncated cone 49 and capture the lower bead of the tire 24. Then the pressure chamber 5 rises, as a result of the rivet 24 deformed into a hollow cylinder (Fig. 13-14). in order to free the Nizh-NII Board of the pokryshka 24 from grabbing a growling gami with dogs 46, the architrach of the 1st press raises slightly (Fig. 16). After that, the head 43 is lowered to the lowest position and grinding of tire 24 (Fig. 1718) is carried out in this way. Then the press architrave 1 rises to the extreme upper position, and the pressure chamber 5 descends to the lowest position. In this position, the remainder 35 of the scissors should be removed from the pressure chamber 5. The apertures 8 are also used to press in the rubber mass. The pressure at the same time 20,000 N / cm. W FIG. Figures 20-22 show a piston grinding device with which it is possible to grind all kinds of rubber waste in the form of scraps, for example unvulcanized, vulcanized, perevulcanized rubber cuts and even rubber. In the device of FIG. 20, the pressure chamber 5 has a support plate 50 with a central bore 51 in which a rod 52 of a double-acting hydraulic working cylinder 53 is housed. At the free end of the rod 52, a piston 54 is fastened, limited to the bottom of the cavity of the pressure chamber 5, which can move along the inner side surface of the wall 6 of the pressure chamber 5. The grinding process occurs in this way. To this end, rubber trim 55 to be crushed is placed in pressure chamber 5. When piston 7 is lowered, rubber is crushed through apertures 8. After grinding is completed, possible residue 35 (Fig. 22) can be removed from pressure chamber 5 by piston 54. In Fig. . 23-24 show a grinding apparatus similar to that of FIG. 20-22, in which the piston is formed with a cavity 56 and holes 57 in the base. The piston (figs. 23-24) has outlet openings 58, and outlet openings 8 are made in the chamber. FIG. 25-27 show a variant of the grinding device in which the punching tool is made of two adjoining drums 59 mounted on horizontal shafts 60. The drums 59 are fixed in bearings — rotatable in opposite directions in a common frame 61. In each There is a hollow space in the drums, ending with radial holes 62 for squeezing the rubber mass into the drum shell. The drums form an open pressure chamber 63. On both shafts 60 mounted on gear gear 64, found about {ihs meshed with each other. One of the shafts 60 has a pulley 65 connected to a drive (not shown). The neck 66, mounted above the drums, serves to load rubber pieces (without metal inclusions) into the open pressure chamber 63. In the drums 59, discharge holes 67 are made, for discharging and shredded rubber waste in the cuvettes 66. The device (Fig. 25-26) works as follows. When rotating from the drive of one drum 59 in arrow 68, the second drum 59 turns in rotation in arrow 69, with the result that rubber cuts 70 are drawn into the open chamber 63. The holes 62 on one drum are offset relative to the holes 62 on the other drum. The rubber is pressed in the crushed form into the cavity of the drum, discharged through the holes 67 and cured into the cuvette 66. The drums 59 can be filled with the profile teeth 71 and 71 (Fig. 27) that are in engagement with each other, and the holes 62 for Ignition are made in the troughs 72. The proposed device for grinding rubber waste (its
    variants) at relatively low cost, allows for a very efficient grinding. Operations such as pre-removal of poppek boards are excluded. Rubber waste, along with worn hard wheels, all rubber products and waste during rubber production,
    up to fully vulcanized rubber. Due to the increase in the number of holes for liquefaction, as compared with the prototype, conditions have been created for reducing the pressure to overcome V11 friction, which reduces the energy costs and the overall pressure.
