Description

Technical Field

[0001] This utility model relates to the field of metal recycling, and in particular to a metal recycling system for municipal solid waste incineration slag. Background Technology

[0002] Municipal solid waste incineration refers to the treatment of municipal solid waste through incineration. Incineration is a high-temperature thermal treatment technology in which a certain amount of excess air is used to carry out an oxidative combustion reaction with the organic waste to be treated in an incinerator. Harmful and toxic substances in the waste are destroyed by oxidation and pyrolysis at high temperatures of 800℃ to 1200℃. It is a treatment technology that can simultaneously achieve the harmlessness, volume reduction and resource recovery of waste.

[0003] The existing main equipment uses magnetic separation to screen out iron metals. However, this equipment usually requires slag pulping, which requires the introduction of water sources and causes water pollution. The polluted water also needs to be treated, resulting in excessive costs for metal recycling and hindering the recycling work. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metal recovery system for municipal solid waste incineration slag.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal recycling system for municipal solid waste incineration slag, comprising a recycling bin, a first inclined plate fixedly connected to the inner side wall of the recycling bin, a second inclined plate fixedly connected to the inner side wall of the recycling bin, a first adsorption plate fixedly connected to the inner side wall of the recycling bin, the first adsorption plate being located above the first inclined plate, a second adsorption plate fixedly connected to the inner side wall of the recycling bin, the second adsorption plate being located above the second inclined plate, an electric push rod fixedly connected to the inner side wall of the recycling bin, a push plate fixedly connected to the lower surface of the electric push rod, a stabilizing column fixedly connected to the lower surface of the push plate, a supplementary plate fixedly connected to the lower surface of the stabilizing column, a baffle fixedly connected to the lower surface of the supplementary plate, and a discharge port opened on the right side of the recycling bin.

[0006] As a further description of the above technical solution:

[0007] A rotating shaft is fixedly connected to the front side of the recycling bin, and a rotating bar is fixedly connected to the front side of the rotating shaft. A moving groove is provided on the front side of the rotating bar.

[0008] As a further description of the above technical solution:

[0009] A stabilizing plate is fitted onto the outer surface of the rotating shaft, and a mounting frame is fixedly connected to the front side of the stabilizing plate.

[0010] As a further description of the above technical solution:

[0011] A motor is fixedly connected to the front side of the mounting frame, a turntable is fixedly connected to the output end of the motor, and a locking pin is fixedly connected to the rear side of the turntable, with the locking pin located inside the moving groove.

[0012] As a further description of the above technical solution:

[0013] The bottom of the recycling bin is equipped with a collection box, and a handle is fixedly connected to the right side of the collection box.

[0014] As a further description of the above technical solution:

[0015] The upper surface of the recycling box is fixedly connected to an inlet, which is located above the first inclined plate.

[0016] This utility model has the following beneficial effects:

[0017] Compared with existing technologies, this municipal solid waste incinerator slag metal recovery system, through a first adsorption plate, a second adsorption plate, a feed inlet, a first inclined plate, a second inclined plate, a collection box, an electric push rod, a push plate, a stabilizing column, a replenishing plate, a baffle, and a discharge outlet, operates as follows: During operation, the first and second adsorption plates are energized, allowing crushed slag to be fed in through the feed inlet. The slag then flows down the first and second inclined plates into the collection box, while magnetic metal is attracted to the lower surfaces of the two adsorption plates. After a period of time, the slag feeding stops, and the electric push rod moves the push plate downwards, which in turn moves the stabilizing column, replenishing plate, and baffle downwards. When the upper surface of the replenishing plate is flush with the upper surface of the second inclined plate, the electric push rod stops, de-energizing the first and second adsorption plates. At this point, the metal falls from the two adsorption plates, slides down the first and second inclined plates, and is finally discharged through the discharge outlet, where a receiving box collects the metal. Compared to existing recycling systems, this municipal solid waste incinerator slag metal recycling system directly recovers metals from the slag without the need for water-based pulping, saving water resources, reducing pollution, saving costs, and protecting the environment.

[0018] Compared with existing technologies, this municipal solid waste incinerator slag metal recovery system uses a motor, turntable, locking pin, moving trough, rotating bar, rotating shaft, recovery box, first inclined plate and second inclined plate. The motor drives the turntable to rotate, which in turn drives the locking pin to rotate. Due to the presence of the moving trough, the rotating bar can be driven to deflect and sway back and forth, which in turn drives the rotating shaft to deflect and sway back and forth, which in turn drives the recovery box to deflect and sway back and forth, thus preventing the slag on the first inclined plate and second inclined plate from adhering and not falling off.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Reference Figure 1-7This utility model provides a metal recycling system for municipal solid waste incineration slag: It includes a recycling bin 1, with a first inclined plate 2 and a second inclined plate 3 fixedly connected to the inner wall of the recycling bin 1, a first adsorption plate 4 located above the first inclined plate 2, and a second adsorption plate 5 fixedly connected to the inner wall of the recycling bin 1, located above the second inclined plate 3. Electromagnets are installed inside the first and second adsorption plates 4 and 5, which become magnetic when energized. An electric push rod 6 is fixedly connected to the inner wall of the recycling bin 1.

[0030] During operation, the first adsorption plate 4 and the second adsorption plate 5 are energized, and the crushed slag is fed in through the feed inlet 21. The slag then flows into the collection box 19 along the first inclined plate 2 and the second inclined plate 3. At the same time, the magnetic metal is attracted to the lower surface of the two adsorption plates. After a period of time, the slag feeding is stopped, and the electric push rod 6 moves the push plate 7 downward, which in turn moves the stabilizing column 8, the supplementary plate 9, and the baffle 10 downward. When the upper surface of the supplementary plate 9 is flush with the upper surface of the second inclined plate 3, the electric push rod 6 stops working, and the first adsorption plate 4 and the second adsorption plate 5 are de-energized. At this time, the metal falls from the two adsorption plates and finally slides down the first inclined plate 2 and the second inclined plate 3, and is finally discharged through the discharge outlet 11. The discharge port 11 receives metal from the external receiving box. The waste residue is sent to the crusher for fine crushing, and then the particles of different sizes are further classified by the vibrating screening equipment to extract non-magnetic metals. The lower surface of the electric push rod 6 is fixedly connected to the push plate 7, and the lower surface of the push plate 7 is fixedly connected to the stabilizing column 8. The stabilizing column 8 is used to connect the push plate 7 and the supplementary plate 9. The lower surface of the stabilizing column 8 is fixedly connected to the supplementary plate 9, and the lower surface of the supplementary plate 9 is fixedly connected to the baffle 10. The right side of the recycling box 1 has a discharge port 11. The baffle 10 can block the discharge port 11 so that the slag part will not pass through the discharge port 11.

[0031] A rotating shaft 22 is fixedly connected to the front side of the recycling bin 1. A rotating bar 13 is fixedly connected to the front side of the rotating shaft 22. A moving groove 14 is provided on the front side of the rotating bar 13. A stabilizing plate 12 is fitted onto the outer surface of the rotating shaft 22. A mounting frame 15 is fixedly connected to the front side of the stabilizing plate 12. A motor 16 is fixedly connected to the front side of the mounting frame 15. A turntable 17 is fixedly connected to the output end of the motor 16. A locking pin 18 is fixedly connected to the rear side of the turntable 17. The locking pin 18 is located inside the moving groove 14. A collection box 19 is provided at the bottom of the recycling bin 1. A handle 20 is fixedly connected to the right side of the collection box 19. When the motor 16 operates, it drives the turntable 17 to rotate, which in turn drives the locking pin 18 to rotate. Due to the presence of the moving groove 14, the rotating bar 13 can be driven to deflect and sway back and forth, which in turn drives the rotating shaft 22 to deflect and sway back and forth, which in turn drives the recycling bin 1 to deflect and sway back and forth, thus preventing slag on the first inclined plate 2 and the second inclined plate 3 from adhering and falling off. The remaining slag falls into the collection box 19. Pulling the handle 20 can remove the collection box 19, making it easier to remove the slag for further processing.

[0032] The upper surface of the recycling box 1 is also fixedly connected to the inlet 21, which is located above the first inclined plate 2 and is used to feed slag.

[0033] Working principle:

[0034] During operation, the first adsorption plate 4 and the second adsorption plate 5 are energized, allowing the crushed slag to be fed into the inlet 21. The slag then flows along the first inclined plate 2 and the second inclined plate 3 into the collection box 19. Simultaneously, magnetic metal is attracted to the lower surface of the two adsorption plates. After a period of time, the slag feeding is stopped, and the electric push rod 6 moves the push plate 7 downward, which in turn moves the stabilizing column 8, the supplementary plate 9, and the baffle 10 downward. When the upper surface of the supplementary plate 9 is flush with the upper surface of the second inclined plate 3, the electric push rod 6 stops working, and the first adsorption plate 4 and the second adsorption plate 5 are de-energized. At this point, the metal falls from the two adsorption plates and slides down the first inclined plate 2 and the second inclined plate 3, eventually being discharged through the outlet 11. The receiving box outside the outlet 11 collects the metal.
