Description

Technical Field

[0001] This utility model belongs to the field of solid waste recycling technology, specifically relating to a flip magnetic separator for solid waste recycling. Background Technology

[0002] In the process of recycling special materials from solid waste (such as recycling special sand from waste casting membrane shells), the solid waste is usually crushed to a certain extent first, then crushed into fine particles, and finally the special materials are separated from the crushed waste. However, because solid waste is easily mixed with ferromagnetic impurities, these ferromagnetic impurities can easily cause equipment damage and safety hazards in subsequent processes. Therefore, at the front end of the process, it is necessary to use a magnetic separator to separate and remove the ferromagnetic impurities from the solid waste.

[0003] In actual production, magnetic rollers are generally used to remove impurities from solid waste. However, since solid waste has a layer thickness during the conveying process, ferromagnetic impurities on the upper layer of solid waste are easily adsorbed and removed by the magnetic roller. But if the ferromagnetic impurities are on the lower layer of solid waste, the magnetic roller has difficulty removing them, leaving residual ferromagnetic impurities in the waste, which will still affect subsequent processes.

[0004] To address this issue, we designed a rotary magnetic separator for solid waste recycling, providing an alternative technical solution. Utility Model Content

[0005] The purpose of this invention is to provide a flip magnetic separator for solid waste recycling to solve the problems mentioned in the background art regarding the use of existing couplings.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flipping magnetic separator for solid waste recycling, comprising two sets of first and second conveyor belts arranged parallel to each other, a first magnetic roller and a second magnetic roller respectively arranged above the first and second conveyor belts, and a set of arc-shaped guide chutes connecting the output end and the starting end of the first conveyor belt, the guide chutes comprising two sets of arc-shaped plates arranged at equal intervals and a support frame for supporting the arc-shaped plates.

[0007] Preferably, the front end of the arc-shaped plate located on the upper side is connected to a guide plate, which is arranged to converge from front to back.

[0008] Preferably, a dust collection device is provided at the connection point between the second conveyor belt and the guide chute.

[0009] Preferably, both the first magnetic roller and the second magnetic roller are movably mounted on the magnetic roller bracket via a rotating shaft, and both the first magnetic roller and the second magnetic roller are provided with scrapers and waste collection boxes.

[0010] Preferably, the spacing of the guide chutes is set slightly larger than the thickness of the solid waste conveying layer, and both the guide plate and the arc plate are made of highly wear-resistant metal material.

[0011] Preferably, the first conveyor belt and the second conveyor belt move in opposite directions.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Solid waste is flipped between upper and lower layers by the guide chute. Two sets of magnetic rollers are used to magnetically remove impurities from the upper and lower layers of the material, thereby effectively removing ferromagnetic impurities from the solid waste. This helps protect equipment in subsequent processes and makes production and processing safer. Attached Figure Description

[0017] 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.

[0018] Reference Figure 1-2 A rotary magnetic separator for solid waste recycling includes two sets of first conveyor belts 1 and second conveyor belts 8 arranged parallel to each other. A first magnetic roller 2 and a second magnetic roller 9 are respectively arranged above the first conveyor belt 1 and the second conveyor belt 8. An arc-shaped guide chute 4 is connected between the output end and the starting end of the first conveyor belt 1. The guide chute 4 includes two sets of arc-shaped plates 6 arranged at equal intervals and a support frame 5 for supporting the arc-shaped plates 6.

[0019] To address the problem that existing magnetic separation devices for solid waste recycling cannot effectively remove ferromagnetic impurities from the lower layer of solid waste, this solution proposes a flipping magnetic separation device for solid waste recycling. Specifically, the flipping magnetic separation device includes a combination of two sets of conveyor belts and magnetic rollers. During the conveying process of the first conveyor belt 1, the upper layer of solid waste is close to the first magnetic roller 2. The first magnetic roller 2 adsorbs and removes the ferromagnetic impurities from the uppermost layer of solid waste. Subsequently, the solid waste is conveyed to the second conveyor belt 8 through the guide chute 4. Under the action of the arc-shaped guide chute 4 and gravity, the upper and lower layers of solid waste are flipped. The solid waste that was originally located in the lower layer is flipped to the upper layer. Then, driven by the second conveyor belt 8, it passes through the second magnetic roller 9. Since the lower layer of solid waste is flipped to the upper layer, the second magnetic roller 9 can remove the ferromagnetic impurities in the "lower layer" of solid waste, thereby fully removing the ferromagnetic impurities from the solid waste. This is beneficial for protecting the equipment in subsequent processes and makes the production and processing safer.

[0020] Furthermore, the front end of the upper arc plate 6 is connected to a guide plate 3, which is set to converge from front to back.

[0021] With this technical solution, after passing the first magnetic roller 2, the solid waste is driven by the first conveyor belt 1 to continue moving towards the rear end. Finally, the guide plate 3 guides the solid waste into the guide chute 4, and finally, under the gravity of the wire chute, it flips and slides into the second conveyor belt 8.

[0022] Furthermore, a dust collection device 7 is provided at the connection point between the second conveyor belt 8 and the guide chute 4.

[0023] With this technical solution, the outlet of the guide chute 4 is connected to the second conveyor belt 8, so that the solid waste continues to be transported to the rear end. Since the solid waste is broken into sand particles, dust will be generated when the solid waste slides out of the guide chute 4. By setting up a baffle and a dust collection device 7 at the connection between the guide chute 4 and the second conveyor belt 8, the dust can be effectively removed and the cleanliness can be guaranteed.

[0024] Furthermore, the first magnetic roller 2 and the second magnetic roller 9 are both movably mounted on the magnetic roller bracket 10 via the rotating shaft 11, and both the first magnetic roller 2 and the second magnetic roller 9 are provided with scrapers 13 and waste collection boxes 12.

[0025] The first magnetic roller 2 and the second magnetic roller 9 are both equipped with magnets arranged in a certain magnetic field gradient. The second magnetic roller 9 and the second magnetic roller 9 rotate through the rotating shaft 11 (connected to a driving device, not shown in the figure), thereby adsorbing ferromagnetic impurities in the solid waste. The ferromagnetic impurities are adsorbed onto the surface of the magnetic roller and follow the rotation of the magnetic roller until they encounter the scraper 13. The scraper 13 causes the ferromagnetic impurities to slide on the surface of the magnetic roller until they encounter the "zero magnetic zone" of the magnetic roller. At this time, because the adsorption force decreases, the ferromagnetic impurities fall off the magnetic roller and enter the waste collection box 12, completing the collection of waste.

[0026] Furthermore, the spacing of the guide chute 4 is set slightly larger than the thickness of the solid waste conveying layer, and both the guide plate 3 and the arc plate 6 are made of high wear-resistant metal material.

[0027] The spacing between the guide chutes 4 is slightly greater than the thickness of the conveying layer, allowing solid waste to be fully turned over in the guide chutes 4 while preventing the solid waste from mixing in the guide chutes 4. The guide plates 3 and the arc plates 6 are both made of highly wear-resistant metal materials, thus ensuring the service life of the equipment.

[0028] Furthermore, the first conveyor belt 1 and the second conveyor belt 8 move in opposite directions.

[0029] Working principle: The flipping magnetic separator consists of two sets of conveyor belts and magnetic rollers. During the conveying process of the first conveyor belt 1, the upper layer of solid waste is close to the first magnetic roller 2. The first magnetic roller 2 adsorbs and removes the ferromagnetic impurities on the top layer of solid waste. Then, the solid waste is conveyed to the second conveyor belt 8 through the guide chute 4. Under the action of the arc-shaped guide chute 4 and gravity, the upper and lower layers of solid waste are flipped. The solid waste that was originally located on the lower layer is flipped to the upper layer. Then, driven by the second conveyor belt 8, it passes through the second magnetic roller 9. Since the solid waste on the lower layer is flipped to the upper layer, the second magnetic roller 9 can remove the ferromagnetic impurities in the "lower layer" of solid waste, thereby fully removing the ferromagnetic impurities in the solid waste. This is beneficial to protecting the equipment in subsequent processes and makes the production and processing safer.
