[0023] Please see attached Figure 1-6The present invention provides a waste refrigerator disassembly, crushing and recycling line, which includes a pre-disassembly platform 1, a shredder 2, a crusher 3, a first vibration screening machine 4 for receiving materials from the crusher 3 for vibration screening, a magnetic separator 5, an eddy current separator 6 and a plurality of conveyor belts arranged in sequence along the conveying direction; it also includes a hammer fan 7 and a foam material separation device 11; a second vibration screening machine 16 is arranged below the discharge port of the eddy current separator 6; the crusher 3 includes a frame and a crushing mechanism arranged on the frame; the crushing mechanism includes a vertical A cylindrical box body, a knife roller arranged in the box body and a driving device for driving the knife roller are provided; the box body includes a feed port arranged at the top and a discharge port arranged at the bottom; the knife roller includes a vertically arranged rotating shaft and a knife arranged around the rotating shaft; a lining plate is provided on the inner side wall of the box body, and the lining plate includes an upper lining plate arranged in the upper half of the box body and a lower lining plate 23 arranged in the lower half of the box body; the lower lining plate 23 includes an inclined portion 24 inclined from the bottom toward the center of the box body and an extending portion 25 extending vertically downward from the end of the inclined portion 24.

[0024] Based on the above technical features, the service life of the box is increased by arranging a liner, and the material is crushed by impact, contact and crushing between the liner and the cutter roller. By arranging an inclined portion 24 and an extension portion 25, the inclined portion 24 is inclined toward the center of the box to reduce the distance between the liner and the cutter roller, and the crushing and impact time between the material and the cutter roller is increased when the material is under the liner 23, thereby achieving a better crushing effect, improving the crushing efficiency of the crusher 3, and making the material crushing efficiency of the recycling line higher.

[0025] The recycling process of this recycling line is as follows: after the waste refrigerator is disassembled through the pre-disassembly platform 1, the parts to be recycled are conveyed to the shredder 2 through the first conveyor belt 12 for shredding, the preliminarily shredded materials are conveyed to the crusher 3 through the second conveyor belt 13 to crush the preliminarily shredded materials, the crushed materials are vibrated and screened through the first vibrating screen 4, the sun-separated materials are conveyed to the magnetic separator 5 through the third conveyor belt 14 for magnetic separation and classification, and are classified into non-ferrous metals through the eddy current separator, so as to realize the disassembly and screening of the waste refrigerator, and the screened materials of the eddy current separator 6 are screened for secondary screening through the second vibrating screen 16 After that, it is further classified; the first vibrating screening machine 4 passes through the hammer fan 7 again, and the light plastic foam and other materials are transported to the hammer fan 7 through the first pipeline for fragmentation; the heavy metal and other materials are processed through the first vibrating screening machine 4; the disassembled materials are crushed by the hammer fan 7 and transported to the top of the storage hopper 10 through the second pipeline, and the storage hopper 10 is connected to the foam dividing device 11 through the third pipeline. Since the gravity of the foam is small, it is compressed to the foam dividing device 11 under the action of the fan, and the heavy material is stored in the storage hopper 10, thereby realizing the decomposition and recovery of the material.

[0026] The shredder 2 is an oblique push shredder, which includes a frame, a shredding mechanism arranged on the frame, and a push hopper for pouring materials into the shredder; a feed port is arranged on the top of the shredder; the push hopper includes a hopper body 26 for holding materials and a push device arranged in the hopper body 26; the hopper body 26 is inclined in a flared shape along both sides of the axial direction of the shredder, and the push device is arranged on one side of the inclined surface of the hopper body 26; by providing the flared hopper body 26, when the material is thrown into the hopper, it can better make the material slide to the shredding mechanism, and the push device pushes along one side of the inclined surface of the hopper body 26 In this way, the material is pushed close to the shredding mechanism, which speeds up the time for the material to approach the shredding mechanism and improves the shredding efficiency of the shredder; further improves the crushing efficiency of the material in the recycling line; wherein the pushing device includes a pushing box 27 that slides from the shredder along the inclined surface of the hopper body 26 and an oil cylinder 28 connected to the pushing box 27 for driving the pushing box 27; the oil cylinder 28 is fixed on the hopper body 26; through the pushing action of the oil cylinder 28, the pushing box 27 is driven to push from the shredding mechanism along one side of the hopper body 26, thereby realizing the operation of pushing the material to the shredding mechanism and improving the shredding efficiency.

[0027] The shredding mechanism includes a box body, a shredding shaft arranged in the box body, and a driving motor for driving the shredding shaft.

A plurality of locking members for fastening the clamping plate 30 are arranged on the peripheral side of the clamping plate 30. The outer diameter of the clamping plate 30 is larger than the outer diameter of the clamping ring 31. Under the action of the motor, the rotating shaft drives the cutter body to realize the shredding work. By arranging a shifting mechanism 29 on one side of the main shaft, when the cutter body shifts to one side, the fixing setting of the clamping plate 30 is used to realize the tightening and abutment of the cutter body during the shifting. By arranging a clamping ring 31 abutting against one side of the clamping plate 30, and because the outer diameter of the clamping ring 31 is smaller than the inner diameter of the clamping plate 30, the stability of the clamping plate 30 close to the inner diameter side is guaranteed, and the stability of the clamping plate 30 close to the inner diameter side when the cutter body shifts is improved, which ensures that the clamping plate 30 can better realize the stability of the cutter body. By setting the fastening component, the stability of the clamping plate 30 is improved.

[0028] The bottom of the second vibrating screening machine 4 is provided with a first discharging conveyor belt 17 and a second discharging conveyor belt 18 for receiving and conveying the screened materials, so as to realize the conveying and classification of the bulk plastics and nonferrous metals that have not been blown by the hammer blower.

[0029] A fan is provided at the discharge port of the storage hopper 10, a conveyor belt is provided below the fan, one end of the third through pipe is connected to the fan, and foam with smaller mass is conveyed to the second pipeline to the foam distributing device 11 through the fan, and compression is achieved through the foam distributing device 11.

Since at least two discharge ports are arranged, the impeller 32 is driven to rotate under the action of the reducer 33, and the foam particles rotate evenly in the discharge port under the action of the impeller 32 and the foam particles are evenly discharged through the fan shut-offs of each discharge port.

[0031] It also includes a dust collector 19, which is provided with a fourth through pipe connected to the storage hopper 10 and a fifth through pipe connected to the foam distribution device 11. The fourth through pipe is also provided with an extension pipe extending to the shredder 2, the crusher 3 and the first screening machine; by arranging the dust collector 19, dust and harmful gases generated during the disassembly process are eliminated.

[0032] It also includes a filter 20 and a silencer 21, a through pipe with a fan is connected between the filter 20 and the silencer 21, and the filter 20 is provided with a sixth through pipe connected to the dust collector 19; the filter 20 is provided to filter out harmful gases and the silencer 21 is used to reduce noise during the production process.

[0033] The hammer-type fan 7 includes a frame, a crushing box, an impeller box, a hammer, an impeller and a motor. The crushing box, the impeller box and the motor are all arranged on the frame.

This avoids the phenomenon that the long materials are wrapped around the impeller when the hammer and the impeller are integrated, causing blockage and suffocation of the equipment, ensuring smooth feeding and improving production efficiency. At the same time, the hammer is detachably installed in the crushing box. When it needs to be replaced or repaired, it only needs to be removed. It is simple and convenient, and the maintenance cost is reduced.
