Description

Technical Field

[0001] The utility model relates to the technical field of recycling processing devices, in particular to a tearing crusher. Background Art

[0002] In the prior art, for recycling large products, such as refrigerators, a tearing machine is usually used to tear the outer shell and large parts of the large products into smaller pieces, and then a crusher is used to further crush the torn materials into smaller particles for easy classification and recycling. For example, a Chinese patent with announcement number CN210546966U discloses a waste refrigerator disassembly and crushing recycling line, which uses a shredder and a crusher to process the refrigerator respectively. Since the shredder and the crusher are not integrated, the space occupancy rate of the two devices is large, and the material needs to be transported, which reduces the recycling efficiency. Utility Model Content

[0003] In view of the above problems in the prior art, the utility model provides a tearing and crushing machine, which solves the problem of low recycling efficiency caused by the lack of integrated arrangement of the existing tearing and crushing machines.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A tearing crusher is provided, comprising: a chassis, which is fixed on a frame, and comprises, from top to bottom, a tearing chamber, a crushing chamber and a discharging chamber which are interconnected; a blade assembly, which comprises a rotating shaft rotatably arranged on the frame and located on the central axis of the crushing chamber, on which a cutter seat and two roller discs are fixed from top to bottom, the cutter seat is located in the tearing chamber and is provided with a plurality of cutters, and the rotating shaft drives the plurality of cutters to rotate to collide and tear the materials in the tearing chamber; the two roller discs are both located in the crushing chamber, and each roller disc is provided with a plurality of rollers rotatably arranged in a circumferential direction, and the roller disc drives the plurality of rollers thereon to roll, extrude and crush the materials located on the inner wall of the crushing chamber; a motor assembly, which is fixed on the frame, and comprises at least one motor drivingly connected to the rotating shaft.

[0006] The working principle of this scheme is to put large materials into the tearing chamber, and the rotating shaft drives multiple cutters to rotate to collide and tear the materials in the tearing chamber into strips or blocks. The torn materials fall into the crushing chamber from the gap between the tearing chamber and the cutter seat. The roller disc in the crushing chamber drives multiple rollers on it to roll, squeeze and crush the materials on the inner wall of the crushing chamber. The materials are further crushed under the shear force and kneading of the rollers and enter the discharge chamber. This scheme integrates the tearing machine and the crusher into one, which not only reduces the occupied space, but also does not require material transmission, thereby improving the recycling efficiency.

[0007] Furthermore, multiple lining plates are fixed on the inner wall surfaces of the tearing cavity and the crushing cavity. The lining plates are made of highly wear-resistant materials such as manganese steel. The lining plates can effectively withstand the impact and wear generated when the high-speed rotating cutter and hob crush the material, improving the service life of the tearing cavity and the crushing cavity.

[0008] Furthermore, the crushing cavity is a conical structure with openings at both ends. The large-diameter end of the crushing cavity is connected to the bottom of the tearing cavity, and the small-diameter end of the crushing cavity is connected to the top of the discharge cavity. The conical structure of the crushing cavity is conducive to gradually reducing the distance between the hob and the inner wall of the crushing cavity, thereby gradually improving the crushing effect of the hob on the material. The torn and disintegrated material in the high-speed running hob crushing cavity is continuously rubbed back and forth, gradually forming a more and more compact mass of material from top to bottom.

[0009] Furthermore, the cutter holder includes a bottom plate fixed on the rotating shaft. The bottom plate is located at the connection of the tearing cavity and the crushing cavity, and two mounting seats are arranged on the bottom plate and are perpendicular to each other. Both mounting seats are fixed on the top of the rotating shaft, and a cutter is fixed at each end of each mounting seat. The cutter is used to collide and tear large materials.

[0010] Furthermore, the frame includes a first platform, a second platform, and a third platform. The second platform is located between the first platform and the second platform, and the height of the second platform is greater than the height of the third platform, and the height of the third platform is greater than the height of the first platform; the middle and bottom ends of the rotating shaft are rotatably arranged on the second platform and the bottom of the frame through bearings respectively; the motor assembly includes two motors respectively fixed on the first platform and the second platform, and both motors are belt-drivenly connected to the rotating shaft. Using two motors as a redundant design improves the safety and reliability of power transmission, and the two motors can jointly bear the load, reducing the load of each motor and extending the service life of the motor.

[0011] Furthermore, a driven pulley is arranged on the rotating shaft below the second platform; main pulleys are arranged on the output shafts of the two motors, and both main pulleys are belt-drivenly connected to the driven pulley through belts.

[0012] Furthermore, the motor assembly also includes a controller, and the controller is electrically connected to the two motors and the temperature probe respectively. The temperature probe is arranged on the bearing seat that is rotatably connected to the rotating shaft at the bottom of the frame. The temperature probe can detect the temperature of the bearing seat. When the temperature of the bearing seat is relatively high, the controller can automatically turn off the motor to avoid the high temperature affecting the lubrication performance of the bearing lubricant in the bearing seat.

[0013] Furthermore, a camera is arranged on the top plate of the tearing cavity. The camera is convenient for workers to monitor the tearing situation in the tearing cavity.

[0014] Further, a discharge port is provided on the wall of the discharge chamber. A scraper seat fixed to the rotating shaft is arranged in the discharge chamber, and two scrapers for scraping the material to the discharge port are fixed on the scraper seat. The arrangement of the scrapers facilitates the discharge of the material.

[0015] Further, the discharge port of the discharge chamber is communicated with a discharge hopper. An exhaust gas discharge port is provided at the top of the discharge hopper, and a star-shaped discharger is provided at the bottom outlet of the discharge hopper. The star-shaped discharger can prevent the material from being blocked.

[0016] The utility model discloses a tearing crusher, and its beneficial effects are as follows:

[0017] The utility model integrates a tearing machine and a crusher. Compared with the prior art in which a tearing machine and a crusher are separately arranged, the utility model not only reduces the occupied space, but also does not require material transfer, thereby improving the recycling efficiency.

Detailed implementation manners

[0028] The following describes the detailed implementation manners of the present utility model to facilitate those skilled in the art of this technical field to understand the present utility model. However, it should be clear that the present utility model is not limited to the scope of the detailed implementation manners. For those of ordinary skill in this technical field, as long as various changes are within the spirit and scope of the present utility model defined and determined by the appended claims, these changes are obvious, and all utility models created using the concept of the present utility model are within the scope of protection.

[0029] In the prior art, a tearing machine and a crusher are respectively used for the recycling of large-piece product materials, which occupy a large space and require the transportation of materials, resulting in low recycling efficiency. In order to solve the problem of low recycling efficiency caused by the non-integrated setting of the existing tearing machine and crusher, the present application connects the tearing chamber 10 and the crushing chamber 11, and sets a blade assembly 200 therein. After the tearing chamber 10 tears the material, it directly enters the crushing chamber 11 for crushing, without an additional conveying structure, reducing the floor space and achieving the effect of improving the recycling efficiency.

[0030] Specifically, referring to Figures 1 to 3 , this embodiment provides a tearing crusher, which includes a chassis 100, a blade assembly 200, a motor assembly 300 and a frame 400.

[0031] The frame 400 is fixed on the ground and plays a supporting role.

[0032] Referring to Figure 4 , the chassis 100 is fixed on the frame 400. The chassis 100 successively includes a tearing chamber 10, a crushing chamber 11 and a discharging chamber 12 that are interconnected from top to bottom.

[0033] A camera is provided on the top plate of the tearing chamber 10. The camera facilitates workers to monitor the tearing situation in the tearing chamber 10.

[0034] On the inner wall surfaces of the tearing chamber 10 and the crushing chamber 11, multiple lining plates 101 are fixed. The material of the lining plates 101 is a highly wear-resistant material, such as manganese steel. The lining plates 101 can effectively withstand the impact and wear generated when the high-speed rotating cutting knives 213 and hob cutters 221 crush the material, and improve the service life of the tearing chamber 10 and the crushing chamber 11.

[0035] The crushing chamber 11 is in a conical structure with both ends open. The large-diameter end of the crushing chamber 11 is communicated with the bottom of the tearing chamber 10, and the small-diameter end of the crushing chamber 11 is communicated with the top of the discharge chamber 12. The conical structure of the crushing chamber 11 is conducive to gradually reducing the distance between the hob cutter 221 and the inner wall of the crushing chamber 11, so as to gradually improve the crushing effect of the hob cutter 221 on the material, and make the material after tearing and disintegration continuously rub against each other in the high-speed running hob cutter 221 crushing chamber 11, thus gradually forming a more and more compact mass of material from top to bottom.

[0036] Reference Figures 5 to 7 , the blade assembly 200 includes a rotating shaft 23 rotatably arranged on the frame 400 and located on the central axis of the crushing chamber 11. A cutting tool holder 21 and two hob cutter discs 22 are successively fixed on the rotating shaft 23 from top to bottom. The cutting tool holder 21 is located in the tearing chamber 10 and is provided with multiple cutting knives 213 thereon. The rotating shaft 23 drives the multiple cutting knives 213 to rotate to collide and tear the material in the tearing chamber 10.

[0037] Both of the two hob cutter discs 22 are located in the crushing chamber 11, and multiple hob cutters 221 are rotatably arranged on each hob cutter disc 22 along the circumferential direction.

[0038] The motor assembly 300 is fixed on the frame 400, and the motor assembly 300 includes two motors 31 drivingly connected to the rotating shaft 23.

[0039] As the specific structure of the cutting tool holder 21, the cutting tool holder 21 includes a bottom plate 211 fixed on the rotating shaft 23. The bottom plate 211 is located at the connection of the tearing chamber 10 and the crushing chamber 11, and two mounting seats 212 arranged perpendicular to each other are provided on the bottom plate 211. Both of the two mounting seats 212 are fixed on the top of the rotating shaft 23, and one cutting knife 213 is fixed at each end of each mounting seat 212. The cutting knife 213 is used to collide and tear large materials.

[0040] As the specific structure of the frame 400, the frame 400 includes a first platform 41, a second platform 42 and a third platform 43. The second platform 42 is located between the first platform 41 and the second platform 42, and the height of the second platform 42 is greater than the height of the third platform 43, and the height of the third platform 43 is greater than the height of the first platform 41.

[0041] Bearing seats 44 are provided both on the second platform 42 and at the bottom of the frame 400. The middle and bottom ends of the rotating shaft 23 are respectively rotatably arranged on the second platform 42 and at the bottom of the frame 400 through the bearings in the two bearing seats 44.

[0042] As the specific structure of the motor assembly 300, refer to Figure 4 , the motor assembly 300 includes two motors 31 respectively fixed on the first platform 41 and the second platform 42. Both of the two motors 31 are connected to the rotating shaft 23 by belt drive. Using two motors 31 for redundant design improves the safety and reliability of power transmission, and the two motors 31 can share the load together, reducing the load on each motor 31 and extending the service life of the motors 31.

[0043] To achieve the belt drive between the two motors 31 and the rotating shaft 23, a driven pulley 231 is arranged on the rotating shaft 23 below the second platform 42, and a plurality of pulley grooves are arranged on the driven pulley 231; main pulleys 311 are arranged on the output shafts of the two motors 31, and both of the two main pulleys 311 are connected to the driven pulley 231 by belts for belt drive.

[0044] To avoid the high temperature affecting the lubrication performance of the lubricant in the bearing of the bearing seat 44, the motor assembly 300 further includes a controller, and the controller is electrically connected to the two motors 31 and the temperature probe 32 respectively. Refer to Figure 8 , the temperature probe 32 is arranged on the bearing seat 44 rotatably connected to the rotating shaft 23 at the bottom of the frame 400. The temperature probe 32 can detect the temperature of the bearing seat 44. When the temperature of the bearing seat 44 is relatively high, the controller can automatically turn off the motor 31. The control in this embodiment is preferably a PLC.

[0045] As the specific structure of the discharge chamber 12, a discharge port is arranged on the wall of the discharge chamber 12, and a scraper seat 121 fixed on the rotating shaft 23 is arranged in the discharge chamber 12. Two scrapers 121 for scraping the material to the discharge port are fixed on the scraper seat 121. The arrangement of the scrapers 121 facilitates the discharge of the material.

[0046] The discharge port of the material chamber is communicated with the discharge hopper 13, and an exhaust gas discharge port 131 is arranged at the top of the discharge hopper 13. To avoid material blockage, refer to Figure 9 , a star-shaped discharger 132 is arranged at the bottom outlet of the discharge hopper 13. The star-shaped discharger 132 is a prior art, and its model can be YCD-HX.

[0047] In summary, the working principle of this solution is:

[0048] Put the large material into the tearing chamber 10, the rotating shaft 23 drives the multiple cutters 213 to rotate and collide and tear the material in the tearing chamber 10 into strips or blocks, and the torn material falls into the crushing chamber 11 from the gap between the tearing chamber 10 and the cutter seat 21. The roller cutter disc 22 in the crushing chamber 11 drives the multiple roller cutters 221 thereon to roll, squeeze and crush the material on the inner wall of the crushing chamber 11. The material is further crushed under the shear force and kneading action of the roller cutters 221 and enters the discharge chamber 12. This solution integrates the tearing machine and the crusher into one, which not only reduces the occupied space, but also does not require material transmission, thereby improving the recycling efficiency.
