Description

Technical Field

[0001] This utility model relates to the field of magnetic separation device technology, specifically a magnetic separation device for the treatment and reuse of waste incineration slag. Background Technology

[0002] The main components of waste incineration ash are molten slag and brick / stone, containing small amounts of metals such as iron, aluminum, and copper, and mixed with some ceramics, glass, and other impurities. When the municipal solid waste incinerator is not operating well, the ash may also contain a small amount of unburned waste (paper, plastic, rubber, etc.). Waste incineration ash is mainly composed of gravel particles (particles >2mm account for more than 60%); dissolved salt content ≤1%; low leaching toxicity; the main crystalline phases are SiO2, CaAl2Si2O8, Al2SiO5, CaCO3, and ZnMn2O4. Waste incineration ash is very suitable for resource utilization.

[0003] Since waste incineration slag typically contains a large amount of irregularly shaped solid materials of varying particle sizes, including metals, inorganic materials (such as ash), glass, and ceramics, and the metallic components among these materials are generally strongly magnetic while the other materials are not, these magnetic metallic components can be reused. Therefore, we propose a magnetic separation device for the treatment and reuse of waste incineration slag. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic separation device for the treatment and reuse of waste incineration slag, comprising a supporting base plate, a fixing bolt fixedly connected to the upper end of the supporting base plate, a magnetic separator cylinder fixedly connected to the end of the fixing bolt away from the supporting base plate, a feeding port opened at the upper end of the magnetic separator cylinder, a fixing plate fixedly connected to the surface of the fixing bolt, and a rotating bolt rotatably connected to the upper end of the fixing plate.

[0007] As a further preferred embodiment of this technical solution, the number of fixing bolts is set to two, and the two fixing bolts are symmetrically arranged about the center of the magnetic separator. The lower end of the rotating bolt is rotatably connected to the upper end of the supporting base plate, and the magnetic separator is located in front of the rotating rod.

[0012] This utility model provides a magnetic separation device for the treatment and reuse of waste incineration slag, which has the following beneficial effects:

[0013] (1) By rotating the roller, the waste incineration slag will fall into the inner wall surface of the magnetic separator under the action of centrifugal force and the rotation of the processing plate. At the same time, due to the presence of an elastic pad, when the waste incineration slag falls onto the elastic pad, several vibration springs are fixedly connected inside the elastic pad, so the waste incineration slag will vibrate above the elastic pad. When the magnetic metal is vibrated and comes into contact with the inner wall surface of the magnetic separator, it will be attracted to the inner wall surface of the magnetic separator. The upper part of the magnetic separator is made of permanent magnet, which can attract magnetic metal to its surface, thereby effectively improving the magnetic separation efficiency of waste crushing slag.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution as follows: Figures 1 to 4 As shown in this embodiment, a magnetic separation device for the treatment and reuse of waste incineration slag includes a supporting base plate 1. A fixing bolt 2 is fixedly connected to the upper end of the supporting base plate 1. A magnetic separator 5 is fixedly connected to the end of the fixing bolt 2 away from the supporting base plate 1. A feeding port 6 is opened at the upper end of the magnetic separator 5. A fixing plate 3 is fixedly connected to the surface of the fixing bolt 2. A rotating bolt 4 is rotatably connected to the upper end of the fixing plate 3.

[0022] The upper end of the support base plate 1 is fixedly connected to a support pad 7. The end of the support pad 7 away from the support base plate 1 is fixedly connected to a rotating motor 8. The output end of the rotating motor 8 is rotatably connected to a rotating shaft 9. The end of the rotating shaft 9 away from the rotating motor 8 is fixedly connected to a rotating rod 10.

[0023] The number of fixing bolts 2 is set to two, and the two fixing bolts 2 are symmetrically arranged about the center of the magnetic separator 5. The lower end of the rotating bolt 4 is rotatably connected to the upper end of the support base plate 1. The magnetic separator 5 is located in front of the rotating rod 10.

[0024] The magnetic separator 5 has a snap-fit ​​cover plate 15 attached to its surface. An electric telescopic rod 11 is fixedly connected to the bottom of the inner wall of the magnetic separator 5. A docking plate 12 is fixedly connected to the end of the electric telescopic rod 11 away from the bottom of the inner wall of the magnetic separator 5. A pushing scraper 13 is fixedly connected to the front of the docking plate 12. The surface of the pushing scraper 13 is slidably connected to the inner wall of the magnetic separator 5. By opening the snap-fit ​​cover plate 15 and activating the electric telescopic rod 11, the electric telescopic rod 11 will push the pushing scraper 13 on the surface of the docking plate 12, thereby pushing the metal components adsorbed on the inner wall of the magnetic separator 5, so that the user can obtain the metal after magnetic separation.

[0025] The rotating rod 10 is fixedly connected to a rotating roller 14 at the end away from the rotating shaft 9. A processing plate 17 is fixedly connected to the surface of the rotating roller 14. The number of processing plates 17 is set to several, and all processing plates 17 are fixedly connected to the surface of the rotating roller 14. The waste incineration slag to be reused is added into the magnetic separator 5 through the feeding port 6. At this time, the rotating motor 8 above the support pad 7 is started. The rotating motor 8 will drive the rotating shaft 9 at its output end to rotate together. Due to the rotation of the rotating shaft 9, it will further drive the rotating rod 10 on its front to rotate together. Since the rotating rod 10 is fixedly connected to the rotating roller 14 at the end away from the rotating shaft 9, the rotating rod 10 will drive the rotating roller 14 inside the magnetic separator 5 to rotate together.

[0026] The number of processing plates 17 is also set to several, and several processing plates 17 are fixedly connected to the surface of the rotating roller 14. An elastic pad 18 is fixedly connected between every two processing plates 17.

[0027] The bottom of the inner wall of the elastic pad 18 is fixedly connected to a vibration spring 19. The number of vibration springs 19 is set to several, and each vibration spring 19 is fixedly connected inside the vibration spring 19. A sealing plate 16 is snapped onto the surface of the elastic pad 18. As the rotating roller 14 rotates, when the waste incineration ash falls onto the processing plate 17 above the rotating roller 14 and onto the elastic pad 18, the waste incineration ash will fall onto the inner wall surface of the magnetic separator 5 under the action of centrifugal force and the rotation of the processing plate 17. At the same time, because of the elastic pad 18, when the waste incineration ash falls onto the elastic pad 18, the waste incineration ash will vibrate above the elastic pad 18 because the elastic pad 18 is fixedly connected to several vibration springs 19. When the magnetic metal is vibrated and comes into contact with the inner wall surface of the magnetic separator 5, it will be attracted to the inner wall surface of the magnetic separator 5. The upper part of the magnetic separator 5 is made of permanent magnet, which can attract magnetic metal to its surface.

[0028] This utility model provides a magnetic separation device for the treatment and reuse of waste incineration slag, the specific working principle of which is as follows:

[0029] During use, the user needs to add the waste incineration ash to be reused into the magnetic separator 5 through the feeding port 6. Then, by activating the rotating motor 8 above the support pad 7, the motor 8 drives the rotating shaft 9 at its output end to rotate. The rotation of the rotating shaft 9 further drives the rotating rod 10 on its front to rotate. Since the end of the rotating rod 10 away from the rotating shaft 9 is fixedly connected to the rotating roller 14, the rotating rod 10 drives the rotating roller 14 inside the magnetic separator 5 to rotate. When the waste incineration ash falls onto the processing plate 17 and elastic pad 18 above the rotating roller 14, due to the rotation of the rotating roller 14, the waste incineration ash will be subjected to centrifugal force as it passes through the rotating processing plate 17. The waste ash falls onto the inner wall of the magnetic separator 5 under the push. Simultaneously, due to the presence of an elastic pad 18, when the incinerator ash falls onto the elastic pad 18, several vibration springs 19 are fixedly connected inside the elastic pad 18. This causes the incinerator ash to vibrate above the elastic pad 18. When the magnetic metal is vibrated and comes into contact with the inner wall of the magnetic separator 5, it will be attracted to the inner wall of the magnetic separator 5. The upper part of the magnetic separator 5 is made of permanent magnets, which can attract magnetic metals to its surface. At this time, the snap-fit ​​cover 15 is opened, and the electric telescopic rod 11 is activated. The electric telescopic rod 11 will push the pushing scraper 13 on the surface of the docking plate 12, thereby pushing the attracted metal components on the inner wall of the magnetic separator 5, thus allowing the user to obtain the magnetically separated metal.
