Description

Technical Field

[0001] This utility model belongs to the field of screening equipment technology, specifically a magnetic separation screening device. Background Technology

[0002] Magnetic separation and screening devices are multifunctional equipment. They utilize the principle of magnetic separation, relying on a magnetic source to generate a magnetic field to separate magnetic and non-magnetic substances from materials. Simultaneously, the screening section uses screens and vibrating devices to separate particles by size. Components include magnetic separator drums and screens of different materials. They are widely used in material handling in industries such as mining and chemicals.

[0003] Existing magnetic separation screening equipment involves passing the material to be screened through a magnetic drum. Subsequently, some of the magnetic material adheres to the drum and is then collected by being scraped off by a scraper.

[0004] Existing magnetic separators place the material directly on top of the separator and allow it to slide down freely. During this process, some of the material dust is stirred up, resulting in material waste. At the same time, when the dust falls onto the equipment, it can affect the operation of the equipment.

[0005] Therefore, this utility model provides a magnetic separation and screening device. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The magnetic separation and screening device of this utility model includes a magnetic separator body; a magnetic separation drum is installed inside the magnetic separator body; a guide plate is fixedly connected to the inner side wall of the magnetic separator body; a dual-zone box is fixedly connected to the side wall of the magnetic separator body; multiple air guide chambers are fixedly connected to the inner side wall of the magnetic separator body; multiple air jet pipes are connected to the side wall of the air guide chambers; multiple air jet holes are opened in the middle of the air jet pipes; an air supply pipe is connected to the side wall of the air guide chambers; the output end of the air jet hole is set towards the magnetic separation drum; in use, first connect the air supply pipe to the air pump, and then place the material to be screened into the magnetic separator body. At the top of the magnetic separator, the material slides down from the top of the separator body. It flows downwards through the guide plate and passes through the magnetic separation drum, where it is screened and then falls into the dual-zone box for classified collection. While material is flowing at the top of the separator, an air pump delivers air into the air chamber and air jet pipe. The air is then ejected from the air jet holes. Because the air jet holes are oriented towards the magnetic separation drum, the material, including dust, at the top of the drum flows synchronously towards the bottom of the guide plate. This design reduces material scattering caused by dust when material is flowing at the top of the separator, thus reducing waste.

[0008] Furthermore, an electric push rod is installed at the top; a support frame is fixedly connected to the output end of the electric push rod; a cleaning ring is fixedly connected to the bottom of the support frame; the cleaning ring is sleeved in the middle of the air jet pipe; a connecting rod connects multiple cleaning rings; the cleaning ring and the air jet pipe are in sliding fit; by sleeved a cleaning ring in the middle of the air jet pipe, the electric push rod can be controlled to repeatedly extend and retract during the process of air jet pipe supplying air to the top of the magnetic separator body, so that the cleaning ring can be driven by the support frame to slide on the surface of the air jet pipe. At this time, the cleaning ring can scrape off the impurities on the surface of the air jet pipe, reducing the problem of air jet hole blockage caused by the accumulation of impurities on the surface of the air jet pipe. The setting of the cleaning ring can make the air jet of the air jet hole smoother.

[0009] Furthermore, a heating tube is fixedly connected to the side wall of the cleaning ring; the heating tube is sleeved in the middle of the jet pipe; by adding a heating tube to the side wall of the cleaning ring, the heating tube can move synchronously on the surface of the jet pipe when the cleaning ring slides, and at the same time the heating tube can heat the jet pipe, so that the tightly attached impurities on the surface of the jet pipe are heated at the same time, so that the attached impurities can be scraped off more easily, further reducing the adhesion of impurities on the surface of the jet pipe.

[0010] Furthermore, multiple guide plates are fixedly connected to the inner sidewall of the dual-zone box; the multiple guide plates are staggered; multiple mesh plates are fixedly connected to the sidewall of the guide plates; by providing multiple guide plates and mesh plates inside the dual-zone box, when filtered material falls from the top of the magnetic separator body, it can fall into the dual-zone box to one side of the guide plate. The arrangement of the guide plates and mesh plates can reduce splashing of material falling into the dual-zone box. At the same time, because the mesh plates are inclined, the material can fall smoothly into the dual-zone box, and the material splashing out of the dual-zone box can be reduced.

[0011] Furthermore, a magnetic plate is fixed to the inner side wall of the dual-zone box; multiple magnetic plates are arranged inside the dual-zone box; by providing multiple magnetic plates inside the dual-zone box, when the magnetic material scraped off from the surface of the magnetic separator falls into the dual-zone box, some of the material can be adsorbed onto the surface of the magnetic plate, which can achieve sufficient collection of magnetic materials and reduce the waste caused by some lighter magnetic materials splashing when falling.

[0012] Furthermore, a bottom plate is slidably connected to the inner side wall of the dual-zone box; a spring is fixedly connected to the bottom of the bottom plate; the bottom of the spring is connected to the dual-zone box; by providing a bottom plate and a spring on the inner side wall of the bottom of the dual-zone box, the impact of materials falling into the dual-zone box can be reduced, thereby reducing the dust problem caused by material breakage.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The magnetic separation and screening device of this utility model, by providing an air jet pipe and an air jet hole, allows the material, including dust, at the top of the magnetic separation barrel to flow synchronously towards the bottom of the guide plate when air is jetted through the air jet hole. This setting can reduce the problem of material scattering caused by dust when there is material flowing at the top of the magnetic separator body, thereby reducing the waste problem caused by material scattering.

[0015] 2. The magnetic separation and screening device of this utility model, by providing multiple guide plates and screens inside the dual-zone box, allows filtered material to fall into the dual-zone box on one side of the guide plates when falling from the top of the magnetic separator body. The arrangement of the guide plates and screens reduces splashing of material falling into the dual-zone box. At the same time, because the screens are inclined, the material can fall smoothly into the dual-zone box, and the splashing of material inside the dual-zone box can be reduced.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 3As shown in the embodiment of this utility model, the magnetic separation and screening device includes a magnetic separator body 1; a magnetic separation drum 11 is installed inside the magnetic separator body 1; a guide plate 12 is fixedly connected to the inner side wall of the magnetic separator body 1; a dual-zone box 13 is fixedly connected to the side wall of the magnetic separator body 1; multiple air guide chambers 14 are fixedly connected to the inner side wall of the magnetic separator body 1; multiple air jet pipes 15 are connected to the side wall of the air guide chambers 14; multiple air jet holes 16 are opened in the middle of the air jet pipes 15; an air supply pipe 17 is connected to the side wall of the air guide chambers 14; the output end of the air jet hole 16 is set towards the magnetic separation drum 11; in use, the air supply pipe 17 is first connected to the air pump, and then the material to be screened is placed on the top of the magnetic separator body 1. When material slides down from the top of the magnetic separator body 1, it flows downward through the guide plate 12. During this process, the material passes through the magnetic separator barrel 11, is screened by the magnetic separator barrel 11, and falls into the dual-zone box 13 for classification and collection. When there is material flowing at the top of the magnetic separator body 1, the air pump can send air into the air chamber 14 and the air jet pipe 15. Then the gas is sprayed out from the air jet hole 16. Since the air jet hole 16 is set towards the magnetic separator barrel 11, when the air is sprayed from the air jet hole 16, the material at the top of the magnetic separator barrel 11, including dust, can flow synchronously towards the bottom of the guide plate 12. This setting can reduce the problem of material scattering caused by dust when there is material flowing at the top of the magnetic separator body 1, thereby reducing the waste caused by material scattering.

[0025] like Figures 2 to 3 As shown, an electric push rod 2 is installed on the top of the 1; a support frame 21 is fixedly connected to the output end of the electric push rod 2; a cleaning ring 22 is fixedly connected to the bottom of the support frame 21; the cleaning ring 22 is sleeved in the middle of the air jet pipe 15; a connecting rod 23 connects multiple cleaning rings 22; the cleaning ring 22 and the air jet pipe 15 are in sliding fit; by sleeved the cleaning ring 22 in the middle of the air jet pipe 15, the electric push rod 2 can be controlled to repeatedly extend and retract during the process of air being sent from the air jet pipe 15 to the top of the magnetic separator body 1, so that the cleaning ring 22 can slide on the surface of the air jet pipe 15 through the support frame 21. At this time, the cleaning ring 22 can scrape off the impurities on the surface of the air jet pipe 15, reducing the problem of blockage of the air jet hole 16 caused by the accumulation of impurities on the surface of the air jet pipe 15. The setting of the cleaning ring 22 can make the air jet of the air jet hole 16 smoother.

[0026] like Figure 3 As shown, a heating tube 3 is fixedly connected to the side wall of the cleaning ring 22; the heating tube 3 is sleeved in the middle of the jet pipe 15; by adding a heating tube 3 to the side wall of the cleaning ring 22, the heating tube 3 can move synchronously on the surface of the jet pipe 15 when the cleaning ring 22 slides, and at the same time the heating tube 3 can heat the jet pipe 15, so that the impurities that are tightly attached to the surface of the jet pipe 15 are heated at the same time, so that the attached impurities can be scraped off more easily, further reducing the adhesion of impurities on the surface of the jet pipe 15.

[0027] like Figure 5As shown, multiple guide plates 4 are fixed to the inner side wall of the dual-zone box 13; the multiple guide plates 4 are staggered; multiple mesh plates 41 are fixed to the side wall of the guide plates 4; by providing multiple guide plates 4 and mesh plates 41 inside the dual-zone box 13, when filtered material falls from the top of the magnetic separator body 1, it can fall into the dual-zone box 13 to one side of the guide plate 4. The arrangement of the guide plates 4 and mesh plates 41 can reduce splashing of material falling into the dual-zone box 13. At the same time, because the mesh plates 41 are inclined, the material can fall smoothly into the dual-zone box 13, and the material splashing out of the dual-zone box 13 can be reduced.

[0028] like Figure 5 As shown, a magnetic plate 5 is fixed to the inner wall of the dual-zone box 13; multiple magnetic plates 5 are arranged inside the dual-zone box 13; by providing multiple magnetic plates 5 inside the dual-zone box 13, when the magnetic material scraped off from the surface of the magnetic separator 11 falls into the dual-zone box 13, some of the material can be adsorbed on the surface of the magnetic plate 5, which can achieve sufficient collection of magnetic materials and reduce the waste caused by some lighter magnetic materials splashing when falling.

[0029] like Figure 5 As shown, a base plate 6 is slidably connected to the inner side wall of the dual-zone box 13; a spring 61 is fixedly connected to the bottom of the base plate 6; the bottom of the spring 61 is connected to the dual-zone box 13; by providing a base plate 6 and a spring 61 on the inner side wall of the bottom of the dual-zone box 13, the impact of materials falling into the dual-zone box 13 can be reduced, thereby reducing the dust problem caused by material breakage.

[0030] During operation, the air supply pipe 17 is first connected to the air pump. Then, the material to be screened is placed on top of the magnetic separator body 1. The material slides down from the top of the magnetic separator body 1 and flows downward through the guide plate 12. During this process, the material passes through the magnetic separation barrel 11 and is screened by the magnetic separation barrel 11 before falling into the dual-zone box 13 for classified collection. When there is material flowing at the top of the magnetic separator body 1, the air pump can send air into the air chamber 14 and the air jet pipe 15. Then, the gas is sprayed out from the air jet hole 16. Since the air jet hole 16 is set towards the magnetic separation barrel 11, when the air jet is sprayed from the air jet hole 16, the material at the top of the magnetic separation barrel 11, including dust, can flow synchronously towards the bottom of the guide plate 12. This setting can reduce the problem of material scattering caused by dust when there is material flowing at the top of the magnetic separator body 1, thereby reducing the waste caused by material scattering. By installing a cleaning ring 22 in the middle of the jet pipe 15, the electric push rod 2 can be repeatedly extended and retracted during the process of the jet pipe 15 supplying air to the top of the magnetic separator body 1. This allows the cleaning ring 22 to slide on the surface of the jet pipe 15 via the support frame 21. At this time, the cleaning ring 22 can scrape off impurities on the surface of the jet pipe 15, reducing the problem of blockage of the jet hole 16 caused by the accumulation of impurities on the surface of the jet pipe 15. The installation of the cleaning ring 22 can make the airflow of the jet hole 16 smoother. By adding a heating pipe 3 to the side wall of the cleaning ring 22, the heating pipe 3 can move synchronously on the surface of the jet pipe 15 while the cleaning ring 22 slides. At the same time, the heating pipe 3 can heat the jet pipe 15, so that the tightly adhered impurities on the surface of the jet pipe 15 are heated at the same time, making the adhered impurities easier to scrape off, further reducing the adhesion of impurities on the surface of the jet pipe 15. By providing multiple guide plates 4 and screen plates 41 inside the dual-zone box 13, when filtered material falls from the top of the magnetic separator body 1, it can fall into the dual-zone box 13 to one side of the guide plates 4. The arrangement of the guide plates 4 and screen plates 41 reduces splashing of material falling into the dual-zone box 13. At the same time, because the screen plates 41 are inclined, the material can fall smoothly into the dual-zone box 13, and the splashing of material inside the dual-zone box 13 can be reduced. By providing multiple magnetic plates 5 inside the dual-zone box 13, when magnetic material scraped off from the surface of the magnetic separator 11 falls into the dual-zone box 13, some of the material can be adsorbed on the surface of the magnetic plates 5, which can achieve sufficient collection of magnetic material and reduce the waste caused by splashing of some lighter magnetic material during falling. By providing a base plate 6 and a spring 61 on the inner side wall of the bottom of the dual-zone box 13, the impact of materials falling into the dual-zone box 13 can be reduced, thereby reducing the dust problem caused by material breakage.
