Description

Technical Field

[0001] This utility model relates to the field of metal recycling technology, and more specifically, to a magnetic separation recycling device for waste metals. Background Technology

[0002] Metal recycling is a key measure for sustainable resource utilization, pollution reduction, and carbon emission reduction. Magnetic separation technology, with its advantages of high efficiency, low cost, and environmental friendliness, has become an important method for metal recycling, especially suitable for the separation of ferromagnetic metals.

[0003] A search revealed that Chinese Patent Publication No. CN214347193U discloses "a magnetic separation device for recyclable metals in construction waste treatment, comprising a support plate and an electromagnet. A support rod is fixedly connected to the top of the support plate, and a fixed plate is fixedly connected to the top of the support rod. Fixed blocks are fixedly connected to both sides of the top of the fixed plate. This utility model uses a servo motor to drive a drive gear to rotate, which in turn drives a driven gear to rotate. The driven gear drives a winding roller to rotate, which winds or unwinds a binding strap. The binding strap drives a locking mechanism to move up or down, which in turn drives a lifting block to move up or down. This causes the lifting block to move the electromagnet up or down, and the electromagnet generates magnetism to recycle the metal. This achieves a reasonable structure, is easy to operate, and has high recycling efficiency, thus solving the problem that previously, metals were picked up manually from construction waste, which was not only time-consuming and labor-intensive but also resulted in incomplete recycling." However, the following drawbacks still exist:

[0004] (1) The device uses an electromagnet to move up and down in the garbage pile to attract metal. When attracting metal, waste will be mixed between two metals, so that the attracted metal contains some impurities, which affects the purity of the magnetically attracted metal.

[0005] (2) This device directly adsorbs metal in the garbage dump. The electromagnet directly contacts the metal surface. If the metal surface contains some liquid, long-term contact will damage the surface of the electromagnet, requiring repair or replacement.

[0006] Therefore, we made improvements and proposed a magnetic separation recycling device for waste metals. Utility Model Content

[0020] In the solution of this utility model:

[0021] 1.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-6 As shown, this embodiment proposes a waste metal magnetic separation recycling device, including a housing 1, a magnetic separation mechanism 2 disposed outside the housing 1, and a drying assembly 3 disposed outside the housing 1.

[0036] like Figure 3 and Figure 6As shown, the magnetic separation mechanism 2 includes a first pressure roller 201, a second pressure roller 202, a first rotating shaft 203, a second rotating shaft 204, a first conveyor belt 205, a second conveyor belt 206, a magnet 207, a first discharge port 208, a second discharge port 209, a guide plate 210, and a feed hopper 211. The first pressure roller 201 and the second pressure roller 202 are rotatably connected to the inner side wall of the housing 1. The first rotating shaft 203 and the second rotating shaft 204 are rotatably connected to the inner side wall of the housing 1. The first conveyor belt 205 and the second conveyor belt 206 are respectively located outside the first rotating shaft 203 and the second rotating shaft 204. The magnet 207 is located inside the housing 1. The first discharge port 208 is located on the side wall of the housing 1. The second discharge port 209 is located on the bottom wall of the housing 1. The guide plate 210 is located inside the housing 1. The feed hopper 211 is connected to the top of the housing 1. Magnet 207 is disposed inside the inner roller of the second conveyor belt 206. The guide plate 210 is V-shaped, with one side located inside the first discharge port 208 and the other side inside the second discharge port 209. There are two first rotating shafts 203 and two second rotating shafts 204. A circular groove is formed inside the second rotating shaft 204 near the first discharge port 208, and magnet 207 is located inside this groove and rotates with the second rotating shaft 204. In use, material is placed into the feed hopper 211, and when the material reaches the first conveyor belt 205, it is conveyed to the first... The material is crushed at the pressure rollers 201 and 202, and then the crushed material falls to the second conveyor belt 206. When the second conveyor belt 206 transports the material to the magnet 207, the material containing metal is attracted to the magnet, while the material without metal falls to one side of the guide plate 210 and is discharged through the first discharge port 208. When the material containing metal is transported by the second conveyor belt 206 to the top of the second discharge port 209, the metal material leaves the magnetic field and falls downwards. It is then guided by the guide plate 210 to the second discharge port 209, thus completing the sorting of metal.

[0037] like Figure 5 As shown, the drying assembly 3 includes a dryer 301, a connecting pipe 302, an air outlet 303, and an air outlet 304.

In use, the dryer 301 is connected to an external power source, and hot air enters the air outlet 303 along the connecting pipe 302. Then, the hot air dries the liquid on the material below through the air outlets 304.

[0038] like Figure 1As shown, circular rods 4 are fixedly connected to the four corners of the bottom of the housing 1, and self-locking casters 5 are bolted to the bottom of each of the four circular rods 4. Two fixing blocks 6 are fixedly connected to the side wall of the housing 1, and a pull rod 7 is rotatably connected between the two fixing blocks 6. When it is necessary to move the device, the device can be moved to the designated position by unlocking the self-locking casters 5 and pulling the pull rod 7, and then the self-locking casters 5 are locked to prevent the device from slipping.

[0039] like Figure 1 and Figure 3 As shown, a scraper 8 is fixedly connected to the inner bottom wall of the housing 1, and a sludge storage tank 9 is slidably connected to the inner bottom wall of the housing 1.

The top of the connecting rod 12 is fixedly connected to the inner top of the housing 1. By setting the circular ring 11 and the connecting rod 12, the air outlet duct 303 can be reinforced, reducing the swaying amplitude of the air outlet duct 303.

[0041] like Figure 3 As shown, baffles 13 are fixedly connected to the opposite side walls inside the housing 1, and the two baffles 13 are located on one side of the first pressure roller 201 and the second pressure roller 202, respectively. The baffles 13 can prevent the material from splashing everywhere and can make the material fully squeezed and crushed by the first pressure roller 201 and the second pressure roller 202.

[0042] like Figure 3 and Figure 4 As shown, a pulley 14 is provided at one end of the first rotating shaft 203 and the second rotating shaft 204. A belt 15 is provided on the outside of the pulley 14. A first motor 16 is fixedly connected to one end of the first rotating shaft 203. A second motor 17 and a third motor 18 are fixedly connected to one end of the first pressure roller 201 and the second pressure roller 202, respectively. A support frame is fixedly connected to the bottom of the first motor 16, the second motor 17, and the third motor 18. The first motor 16 drives the first rotating shaft 203 to rotate, and at the same time, the belt 15 on the first rotating shaft 203 rotates accordingly, driving the second rotating shaft 204 to rotate.

[0043] Specifically, when using this waste metal magnetic separation recycling device: after connecting the first motor 16, the second motor 17, the third motor 18 and the dryer 301 to an external power source and turning them on, the material is put into the feed hopper 211. Then, the first conveyor belt 205 transports the material to the first pressure roller 201 and the second pressure roller 202 for crushing. The crushed material then falls onto the second conveyor belt 206. When the material reaches the magnet 207, the material containing metal is attracted, while the material without metal enters the first discharge port 208 through the guide plate 210. When the material containing metal is transported by the second conveyor belt 206 to the top of the second discharge port 209, the metal material leaves the magnetic field and falls downwards. It is then guided by the guide plate 210 to the second discharge port 209, thus completing the metal sorting.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
