Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, and more specifically, to a magnetic separator. Background Art

[0002] A magnetic separator is a device for separating magnetic products from non-magnetic products. When materials pass through the magnetic field of the magnetic separator, particles with stronger magnetism will be adsorbed onto the magnetic poles of the magnetic separator, while particles with weaker magnetism or non-magnetic particles will be separated from the magnetic particles under the action of gravity, centrifugal force, etc., thereby realizing the separation of materials.

[0003] Currently, the method for separating magnetic products from non-magnetic products is to place all products on a conveyor belt, set the conveyor belt to be inclined, and convey the products from a lower position to a higher position by the conveyor. When passing through the position of the magnetic separator, the magnetic products are adsorbed by the magnetic separator, and the non-magnetic products will slide down to a lower position under the action of gravity, realizing the separation. However, it is found in actual operation that during the transportation of all raw materials together, although the magnetic products will be adsorbed, some non-magnetic products will be blocked by some magnetic products, making it impossible for them to slide down to a lower position, and finally falling into the collection box together with the magnetic products. This results in incomplete separation of materials, and it is necessary to repeatedly separate the products, wasting time and reducing work efficiency. Therefore, a magnetic separator is proposed to solve the above problems. Summary of the Utility Model

Embodiment

[0029] Refer to Figures 1 - 5, the present utility model provides a technical solution: a magnetic separator, including a support frame 1 and a magnetic separation mechanism 3, and a positioning plate 2 is fixedly installed on the top of the support frame 1. The magnetic separation mechanism 3 includes a rotating shaft 31, the rotating shaft 31 is rotatably installed inside the positioning plate 2, one end of the rotating shaft 31 is fixedly installed at the output end of the driving motor 311, a rotating wheel 32 is sleeved outside the rotating shaft 31 and fixedly connected to the rotating shaft 31. A magnetic system 321 is fixedly installed on the outer surface of the rotating wheel 32. An aggregate bin 33 is fixedly installed on the upper surface of the support frame 1. An outer bin 331 is installed outside the aggregate bin 33. A rectangular plate 332 is fixedly installed inside the outer bin 331, and a slidable scraping plate 333 is arranged inside the rectangular plate 332 for scraping off magnetic products.

[0030] In a preferred embodiment, a discharge tube 4 is fixedly installed at the bottom of the support frame 1. The inside of the discharge tube 4 is communicated with the inside of the aggregate bin 33. A control valve is installed on the discharge tube 4. For the convenience of discharging non-magnetic products after material separation, a discharge tube 4 is installed at the bottom of the support frame 1. During operation, only by separating one end of the inclined plate 81 from the closing plate 82, the non-magnetic products can slide down from the inclined plate 81 into the inside of the discharge tube 4, which is convenient for collection.

[0031] In a preferred embodiment, a groove 5 is formed on one side surface of the rectangular plate 332. A spring 6 is fixedly connected to the inner bottom of the groove 5. One end of the spring 6 is fixedly connected to the scraping plate 333. By adsorbing magnetic products with the magnetic system 321, for the convenience of removing the products on the magnetic system 321, a telescopic scraping plate 333 is installed inside the rectangular plate 332, and the scraping plate 333 is pushed by the spring 6, so that the scraping plate 333 can closely adhere to the outer surface of the magnetic system 321, thereby removing the adsorbed products on the magnetic system 321, which is convenient for discharging magnetic products.

[0032] In a preferred embodiment, the rectangular plate 332 is inclined and arranged inside the outer bin 331. A discharge hole 7 is formed at the bottom of the outer bin 331. After the magnetic products are scraped off by the scraping plate 333, they will enter the inside of the outer bin 331. For the convenience of product falling, a discharge hole 7 is installed at the bottom of the outer bin 331. The products are discharged from the inside of the discharge hole 7 into the inside of the external collection frame, which is convenient for product collection.

[0033] When performing powder operations on the mixed raw materials, it is necessary to centrally place the raw materials inside the aggregate bin 33. To improve the adsorption effect on magnetic products, a material receiving mechanism 8 is installed inside the aggregate bin 33. The material receiving mechanism 8 includes an inclined plate 81 and a closing plate 82. The inclined plate 81 is fixedly installed inside the aggregate bin 33 and is arranged in an inclined posture inside the aggregate bin 33. One end of the inclined plate 81 is provided with a closing plate 82. One side surface of the closing plate 82 is fixedly connected to a connecting rod 9. One end of the connecting rod 9 penetrates inside the aggregate bin 33 and is slidably connected to the inside of the aggregate bin 33. The top of the aggregate bin 33 is hinged and installed with a protective cover 10. The protective cover 10 covers the outside of one side of the rotating wheel 32. The inside of the aggregate bin 33 is hollow, and the position at the bottom end of the rotating wheel 32 is arranged inside the aggregate bin 33.

[0034] During actual use, the mixed material is added to the inclined plate 81. While the rotating wheel 32 rotates to drive the magnetic system 321 to rotate, it will also push the raw materials accumulated on the inclined plate 81 towards the higher position of the inclined plate 81. When the magnetic system 321 disengages from the raw materials, the raw materials will slide down from the inclined plate 81 to the lower position, thereby realizing the spreading of the raw materials, avoiding the magnetic products being covered by non-magnetic products, and enabling the magnetic products to be stably adsorbed on the magnetic system 321.

[0035] To improve the use stability of this device, a support base 11 is fixedly installed at the bottom of the support frame 1. A positioning hole 12 is opened at the bottom of the support base 11. During actual use, the support base 11 can be directly placed on the ground for use, or the support base 11 can be fixed to the ground by driving a pin through the inside of the positioning hole 12, thereby improving the use stability of this device.

[0036] Specifically, the working process or working principle of a magnetic separator is as follows: Currently, the method of separating magnetic products and non-magnetic products is to place all products on a conveyor belt, set the conveyor belt to be inclined, and convey the products from the lower position to the higher position through the conveyor belt. When passing through the position of the magnetic separator, the magnetic products are adsorbed by the magnetic separator, and the non-magnetic products will slide down to the lower position under the action of gravity to achieve separation. However, it is found in actual operation that during the transportation of all raw materials together, although the magnetic products will be adsorbed, some non-magnetic products will be blocked by some magnetic products and cannot slide down to the lower position, and finally fall into the collection box together with the magnetic products. This leads to incomplete separation of the materials, and it is necessary to repeatedly separate the products, wasting time and reducing work efficiency. Therefore, this device is designed to solve this problem.

[0037] Through this device, magnetic products can be separated, effectively separating non-magnetic products from magnetic products, avoiding mixing, and performing the separation multiple times, saving time and improving work efficiency. The specific operation is as follows: Connect to an external power supply. Before feeding, rotate the protective cover 10 to expose the position of the top opening of the aggregate bin 33. Then add the mixed material into the interior of the aggregate bin 33 through the opening, and the closing plate 82 will press against one end of the inclined plate 81, preventing the mixed material from sliding down the inclined plate 81 into the interior of the discharge cylinder 4. Since the inclined plate 81 is inclined, the mixed material on the inclined plate 81 will slide towards the lower place, preventing the mixed material from piling up. Then turn on the drive motor 311 and control the rotation of the rotating wheel 32 through the drive motor 311 to control the rotation of the magnetic system 321 and achieve separation of materials.

[0038] While the rotating wheel 32 rotates, it will drive the magnetic system 321 to rotate. The cyclic rotation of the magnetic system 321 will pass through the interior of the aggregate bin 33. At this time, magnetic products will be adsorbed on the magnetic system 321 and will be taken out of the interior of the aggregate bin 33 as the magnetic system 321 rotates. When the magnetic system 321 rotates to the position of the scraping plate 333, the magnetic products adsorbed on the magnetic system 321 will be scraped off by the scraping plate 333. The scraped products will slide into the interior of the outer bin 331 through the rectangular plate 332 and be discharged through the position of the discharge hole 7 to separate the magnetic products.

[0039] While the rotating wheel 32 rotates to drive the magnetic system 321 to rotate, it will also push the raw materials piled up on the inclined plate 81 towards the higher position of the inclined plate 81. When the magnetic system 321 disengages from the raw materials, the raw materials will slide towards the lower place from the inclined plate 81, thereby spreading out the raw materials, preventing magnetic products from being covered by non-magnetic products, enabling magnetic products to be stably adsorbed on the magnetic system 321, separating all magnetic products, and not mixing them with non-magnetic products. The operation is simple, saving time and improving work efficiency.

[0040] After separating the magnetic products, the connecting rod 9 can be pulled to drive the closing plate 82 to move. The connecting rod 9 is clamped inside the aggregate bin 33 and can be stopped at any time when pulled, enabling the closing plate 82 to be stably in a certain position. When pulling the connecting rod 9, the closing plate 82 will be separated from the inclined plate 81. At this time, the raw materials on the inclined plate 81 will fall into the interior of the discharge cylinder 4 through the gap between the inclined plate 81 and the closing plate 82 and can be discharged from the interior of the discharge cylinder 4.

[0041] It should be noted that the drive motor 311 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. Its power supply, specific composition, and principle are clear to those skilled in the art, so no further details will be elaborated.
