The input end of the auger elevator is connected to the waste bin, and the output end of the auger elevator is connected to the dispersing cavity. A dispersing device is installed in the dispersing cavity. The dispersing device includes a dispersing rod, a dispersing bar, and a dispersing motor. With the dispersing device and the crushing device, after the operator pours the waste into the waste bin, he controls the auger elevator to add the waste from the waste bin into the dispersing cavity. Then, the operator controls the dispersing motor and the crushing motor to work, thereby dispersing and crushing the waste through the rotation of the dispersing bar and the crushing wheel, which facilitates the separation and adsorption of metal.

[0004] The existing technical solutions described above have the following drawbacks: the electromagnetic chuck is used to adsorb metal waste in the separation tube, but since the electromagnetic chuck is installed inside the separation tube, when the electromagnetic chuck is full of metal waste, the waste in the separation tube needs to be emptied first before the metal waste on the electromagnetic chuck can be cleaned, which reduces the ease of use of the device. In view of the above situation, technical innovation is carried out on the basis of the existing magnetic metal separation device for waste treatment. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 A magnetic metal separation device for waste treatment includes a support frame 2. An electric hoist 24 is fixedly installed on the top of the support frame 2. A clearance groove is opened through the top of the support frame 2. The cable of the electric hoist 24 passes through the clearance groove and is connected to a partition 23. An electromagnet 21 is fixedly installed at the bottom of the partition 23. When the crushed waste falls onto the conveyor belt of the conveyor 1, the conveyor belt drives the waste to move to the right. When the waste passes under the electromagnet 21, the electromagnet 21 attracts the metal in the waste. A locking component is installed on the top of the support frame 2. Two sets of support plates 3 are evenly fixedly installed on the front side of the support frame 2. A first guide groove is opened on the left and right sides of the inner sidewall of the support frame 2. A second guide groove is opened on the opposite side of the two sets of support plates 3. The first guide groove and the second guide groove are connected. A discharge box 31 is placed between the two sets of support plates 3. The left and right sides of the discharge box 31 are fixedly installed. A set of guide plates 32 are fixedly provided. The guide plates 32 are slidably disposed in the second guide groove and correspond to the first guide groove. The top of the discharge box 31 is provided with an inclined slide groove that runs through the front side of the discharge box 31. The second guide groove runs through the front and rear sides of the support plate 3. The first guide groove runs through the front side of the support frame 2 and is connected to the second guide groove. The top of the support plate 3 is provided with a first insertion hole and a second insertion hole evenly distributed. The first insertion hole is located in front of the second insertion hole. The top of the guide plate 32 is provided with a first through hole. A second pin 33 is inserted into the first insertion hole and the first through hole. The second pin 33 and the first through hole are both corresponding to the second insertion hole. The second pin 33 is inserted into the first insertion hole of the support plate 3 and the first through hole of the guide plate 32, thereby fixing the discharge box 31 in the support plate 3 and limiting the discharge box 31 to the front side of the conveyor 1, thereby preventing the discharge box 31 from affecting the up and down movement of the partition plate 23.

[0024] The locking assembly includes guide posts 22, with two sets of guide posts 22 evenly fixed on the top of the partition 23. Positioning holes are evenly provided on the opposite sides of the two sets of guide posts 22. A guide rail 25 is fixedly installed on the top left side of the guide post 22, and a first sliding groove is provided on the right side of the guide rail 25. A bidirectional lead screw 26 is rotatably installed in the first sliding groove. Two sets of internally threaded sliders 27 are evenly screwed onto the outer wall of the bidirectional lead screw 26. A first pin 28 is fixedly installed on the opposite side of each set of internally threaded sliders 27, and the first pin 28 is inserted into the positioning hole. Two sets of guide holes are evenly provided through the top of the support frame 2. The top of the guide post 22 passes through the guide holes. The front side of the bidirectional lead screw 26 passes through the front side of the guide rail 25 and is connected to a handwheel 29. Rotating the handwheel 29 drives the bidirectional lead screw 26. When the lead screw 26 rotates, it drives two sets of internally threaded sliders 27 to move outward synchronously, thereby separating the first pin 28 from the positioning hole of the guide post 22. At this time, the electric hoist 24 can move the electromagnet 21 up and down through the partition 23 by raising and lowering the cable, thus changing the height of the electromagnet 21. When the partition 23 moves up and down, it drives the guide post 22 to move synchronously. The guide post 22 assists the partition 23 in moving up and down stably. When the positioning hole on the outside of the guide post 22 is aligned with the first pin 28, rotating the reverse handwheel 29 can drive the first pin 28 to insert into the positioning hole, thereby fixing the height of the guide post 22. This, in turn, fixes the height of the partition 23 and the electromagnet 21, preventing electric hoist malfunction. When the electric hoist 24 malfunctions, the electromagnet 21 suddenly drops. When the electric hoist 24 moves the guide column 22 upwards towards the bottom of the inner wall of the support frame 2, the second pin 33 is moved upwards to separate from the support plate 3. Then, the discharge box 31 can be pushed backwards into the support frame 2. At this time, the guide plate 32 will slide its rear end into the first guide groove of the support frame 2 as the discharge box 31 moves. When the first through hole of the guide plate 32 aligns with the second insertion hole of the support plate 3, the second pin 33 can be inserted into the first through hole and the second insertion hole, thus limiting the discharge box 31 within the support frame 2. At this time, the discharge box 31 is located below the electromagnet 21. Then, after the electromagnet 21 is de-energized, the metal magnetically attracted at the bottom of the electromagnet 21 will... The waste falls onto the discharge box 31 and slides forward along the inclined groove of the discharge box 31, thus achieving rapid discharge of metal waste. A conveyor 1 is fixedly installed at the bottom of the support frame 2. A crushing box 11 is fixedly installed on the top left side of the conveyor 1 frame. A first crushing roller 12 and a second crushing roller 15 are rotatably installed inside the crushing box 11. The second crushing roller 15 is located to the right of the first crushing roller 12. The front sides of both the first crushing roller 12 and the second crushing roller 15 penetrate the front side of the crushing box 11 and are respectively connected to a first gear 13 and a second gear 14. The rear sides of both the first crushing roller 12 and the second crushing roller 15 penetrate the rear side of the crushing box 11 and are respectively connected to a first synchronous pulley 17 and a motor 16. The motor 16 is fixedly installed on the rear side of the crushing box 11.A second synchronous pulley 18 is mounted on the rear side of conveyor 1. The drive shaft of conveyor 1 is connected to the second synchronous pulley 18. A synchronous belt 19 is sleeved on the outer side of the second synchronous pulley 18 and the first synchronous pulley 17. The motor 16 drives the second crushing roller 15 to rotate counterclockwise. The second crushing roller 15 drives the first gear 13 to rotate clockwise through the second gear 14. The first gear 13 drives the first crushing roller 12 to rotate clockwise. The first crushing roller 12 drives the second synchronous pulley 18 to rotate clockwise through the first synchronous pulley 17 and the synchronous belt 19. In this way, the second synchronous pulley 18 drives the conveyor 1 to perform clockwise conveying work, pouring the garbage into the crushing box 11. The garbage is crushed by the relatively rotating first crushing roller 12 and second crushing roller 15. The crushed garbage then falls onto the conveyor belt of conveyor 1. The discharge port of the crushing box 11 is located above the conveyor belt of conveyor 1. The support frame 2 is located on the right side of the crushing box 11.

[0025] Working principle: The second pin 33 is inserted into the first insertion hole of the support plate 3 and the first through hole of the guide plate 32, thereby fixing the discharge box 31 in the support plate 3 and limiting the discharge box 31 to the front side of the conveyor 1, thus preventing the discharge box 31 from affecting the up and down movement of the partition plate 23. The motor 16 drives the second crushing roller 15 to rotate counterclockwise. The second crushing roller 15 drives the first gear 13 to rotate clockwise through the second gear 14. The first gear 13 drives the first crushing roller 12 to rotate clockwise. The first crushing roller 12 is driven by the first synchronous pulley. 17 and the synchronous belt 19 drive the second synchronous pulley 18 to rotate clockwise, thereby driving the conveyor 1 to perform clockwise conveying work through the second synchronous pulley 18, pouring the garbage into the crushing box 11, and crushing the garbage through the relatively rotating first crushing roller 12 and second crushing roller 15. Then the crushed garbage will fall onto the conveyor belt of the conveyor 1. When the crushed garbage falls onto the conveyor belt of the conveyor 1, the conveyor belt drives the garbage to move to the right. When the garbage passes under the electromagnet 21, the electromagnet 21 attracts the metal in the garbage.

[0026] By rotating the handwheel 29, the double-ended lead screw 26 is driven to rotate, which in turn drives the two sets of internally threaded sliders 27 to move outward synchronously. This causes the first pin 28 to separate from the positioning hole of the guide post 22. At this time, the electric hoist 24 can move the electromagnet 21 up and down through the partition 23 by raising and lowering the cable, thereby changing the height of the electromagnet 21. When the partition 23 moves up and down, it drives the guide post 22 to move synchronously. The guide post 22 assists the partition 23 to move up and down stably. When the positioning hole on the outside of the guide post 22 is aligned with the first pin 28, rotating the reverse handwheel 29 can drive the first pin 28 to insert into the positioning hole, thereby fixing the height of the guide post 22. This, in turn, fixes the height of the partition 23 and the electromagnet 21, preventing the electromagnet 21 from suddenly changing height if the electric hoist 24 fails. When the electric hoist 24 moves the guide column 22 upwards and approaches the bottom of the inner wall of the support frame 2, the second pin 33 is moved upwards and separated from the support plate 3. Then the discharge box 31 can be pushed backwards into the support frame 2. At this time, the guide plate 32 will slide into the first guide groove of the support frame 2 as the discharge box 31 moves. When the first through hole of the guide plate 32 is aligned with the second insertion hole of the support plate 3, the second pin 33 can be inserted into the first through hole and the second insertion hole to limit the discharge box 31 in the support frame 2. At this time, the discharge box 31 is located below the electromagnet 21. Then, after the electromagnet 21 is de-energized, the metal attracted by the bottom of the electromagnet 21 will fall onto the discharge box 31 and slide forward along the inclined groove of the discharge box 31 to be discharged, thereby realizing the rapid discharge of metal waste.
