Description

Technical Field

[0001] This utility model relates to the technical field of permanent magnet iron separators for coal mines, and in particular to a novel bearing and mechanical cleaning device for permanent magnet iron separators used in coal mines. Background Technology

[0002] During coal mining and transportation, ferromagnetic impurities such as detonators, iron wires, and iron nails are often mixed into the coal flow. In order to prevent ferromagnetic impurities from damaging coal mining equipment such as crushers, permanent magnet separators are usually suspended on the top of the conveyor to adsorb ferromagnetic impurities in the coal flow.

[0003] When cleaning the ferromagnetic impurities adsorbed in the coal flow on the belt of a permanent magnet separator, a rotating brush roller is usually used to scrape the ferromagnetic impurities adsorbed on the belt and remove them into the iron collection frame, thereby ensuring the cleanliness of the belt surface on the permanent magnet separator.

[0004] However, the friction between the rotating brush roller and the belt surface can easily generate static electricity, causing some small ferromagnetic impurities to adhere to the brush roller, which in turn affects the brush roller's cleaning effect on the ferromagnetic impurities attached to the belt. Utility Model Content

[0005] Therefore, it is necessary to provide a new type of permanent magnet separator bearing and mechanical cleaning device for coal mines to address the problem that some small ferromagnetic impurities easily adhere to the brush roller.

[0006] The device includes: a permanent magnet separator, wherein a brush roller is rotatably connected to the inner wall of the permanent magnet separator, and a first motor is fixedly connected to one end of the brush roller; and a cleaning mechanism, wherein the cleaning mechanism includes a guide frame fixedly connected to the bottom of the permanent magnet separator, the surface of the first motor is fixedly connected to one side of the guide frame, and a scraper and a cleaning plate are provided on the inner wall of the guide frame, wherein the top of the scraper is triangular and the surface of the cleaning plate is comb-shaped.

[0007] In one embodiment, positioning blocks are fixedly connected to both sides of the inner wall of the guide frame, and the inner wall of the cleaning plate is slidably connected to the surface of the positioning blocks.

[0008] In one embodiment, limit blocks are fixedly connected to both sides of the inner wall of the guide frame, and the surface of the scraper contacts the surface of the limit blocks.

[0009] In one embodiment, a fixing frame is slidably connected to both sides of the inner wall of the guide frame, and the surface of the fixing frame is respectively engaged with the inner wall of the scraper and the cleaning plate.

[0010] In one embodiment, two springs are fixedly connected to one side of the fixing frame, and the other end of the springs is fixedly connected to one side of the guide frame. The cleaning plate placed in the guide frame is precisely positioned by a positioning block, and the scraper placed in the guide frame is precisely positioned by a limiting block. This allows the elastic force of the springs to push the fixing frame precisely into the cleaning plate and scraper, simplifying the installation of the cleaning plate and scraper.

[0011] In one embodiment, two limiting rods are fixedly connected to one side of the fixing frame, and the surfaces of the limiting rods are slidably connected to the inner wall of the guide frame. The limiting rods limit the movement of the fixing frame, preventing it from detaching from the inner wall of the guide frame.

[0012] In one embodiment, the bottom of both the guide frame and the cleaning plate forms an angle with the horizontal plane, and the top of the scraper forms an angle with the horizontal plane.

[0013] In one embodiment, the guide frame and the cleaning plate are both stainless steel components, and the scraper, the fixing frame and the spring are all polyurethane rubber components. Beneficial effects

[0014] 1. The scraper removes large ferromagnetic impurities from the permanent magnet separator, reducing direct contact between these impurities and the brush roller. This ensures the effective cleaning of the permanent magnet separator by the brush roller. The comb-shaped cleaning plate cleans the surface of the rotating brush roller, facilitating the timely removal of small ferromagnetic impurities. This maintains the cleanliness of the brush roller surface and prevents excessive accumulation of small ferromagnetic impurities, thereby improving the cleaning effect of the brush roller on the permanent magnet separator.

[0015] 2. By fixing the frame away from the scraper and cleaning plate, the scraper and cleaning plate are disengaged from the guide frame, thus cleaning the surface of the scraper and cleaning plate. This ensures the cleaning effect of the scraper on the permanent magnet separator and the cleaning effect of the cleaning plate on the brush roller. Attached Figure Description

[0028] The following is combined Figures 1-4 This invention describes a novel permanent magnet iron separator for coal mines, which serves as a support and mechanical cleaning device.

[0029] In one embodiment, a novel permanent magnet separator for coal mines, comprising: a permanent magnet separator 100, a brush roller 200 rotatably connected to the inner wall of the permanent magnet separator 100, and a first motor 300 fixedly connected to one end of the brush roller 200; and a cleaning mechanism 400, comprising a guide frame 401 fixedly connected to the bottom of the permanent magnet separator 100, the surface of the first motor 300 fixedly connected to one side of the guide frame 401, and a scraper 402 and a cleaning plate 403 provided on the inner wall of the guide frame 401, the top of the scraper 402 being triangular, and the surface of the cleaning plate 403 being comb-shaped.

[0030] The permanent magnet separator 100 includes a main frame, a second motor, a belt, four pulleys, and a permanent magnet separator. The surfaces of the four pulleys are rotatably connected to the inner wall of the main frame, and the surfaces of the four pulleys are drive-connected to each other via the inner surface of the belt. The surface of the second motor is fixedly connected to one side of the main frame, and the output shaft of the second motor is fixedly connected to one end of one of the pulleys. The surface of the permanent magnet separator is fixedly connected to the inner wall of the main frame, and the bottom of the permanent magnet separator contacts the inner surface of the belt.

[0031] The bristles on the surface of the brush roller 200 are made of nylon, which has high strength and hardness. They can maintain a good shape during long-term friction with the belt on the permanent magnet separator 100 and are not easily worn. This ensures that the brush roller 200 can effectively scrape and clean the belt for a long time.

[0032] It has strong resistance to chemical corrosion: The coal mine environment is relatively complex and may contain various chemicals. The bristles of the nylon components can resist the erosion of these chemicals and extend their service life.

[0033] It has moderate elasticity: The moderate elasticity allows the bristles of the nylon components to apply enough pressure to scrape off ferromagnetic impurities when they come into contact with the belt surface, without causing excessive damage to the belt.

[0034] In this embodiment, when it is necessary to clean ferromagnetic impurities in the coal flow, the permanent magnet separator 100 is hoisted on the top of the coal mine conveyor frame by steel wire rope. An iron collection frame is provided below the discharge port of the guide frame 401, so that the distance between the belt on the permanent magnet separator 100 and the conveyor belt on the conveyor is 150-250mm. The conveyor and the permanent magnet separator 100 are automatically started, and the conveyor works to transport the coal flow. When the coal flow passes under the permanent magnet separator 100 through the conveyor belt, the magnetic field generated by the permanent magnet separator on the permanent magnet separator 100 adsorbs the ferromagnetic impurities in the coal flow onto the surface of the belt.

[0035] After the rotating belt moves away from the permanent magnet separator, it first contacts the scraper 402. The scraper 402 scrapes off the large ferromagnetic impurities attached to the belt and onto the inner bottom wall of the guide frame 401. The first motor 300 is automatically activated. The output shaft of the first motor 300 rotates, driving the brush roller 200 to rotate. The rotating brush roller 200 scrapes off the small ferromagnetic impurities on the belt and onto the inner bottom wall of the guide frame 401, causing the ferromagnetic impurities in the guide frame 401 to slide into the iron collection frame.

[0036] When the bristles on the brush roller 200 rotate and come into contact with the comb-shaped cleaning plate 403, the cleaning plate 403 cleans the small ferromagnetic impurities attached to the bristles, keeping the bristles on the brush roller 200 clean.

[0037] like Figure 3 As shown, positioning blocks 407 are fixedly connected to both sides of the inner wall of the guide frame 401. The inner wall of the cleaning plate 403 is slidably connected to the surface of the positioning blocks 407. Limiting blocks 406 are fixedly connected to both sides of the inner wall of the guide frame 401. The surface of the scraper 402 contacts the surface of the limiting blocks 406. Fixing frames 404 are slidably connected to both sides of the inner wall of the guide frame 401. The surfaces of the fixing frames 404 are respectively snapped into the inner walls of the scraper 402 and the cleaning plate 403. Two springs 405 are fixedly connected to one side of the fixing frame 404. The other end of the springs 405 is fixedly connected to one side of the guide frame 401. The bottoms of the guide frame 401 and the cleaning plate 403 form an angle with the horizontal plane. The top of the scraper 402 forms an angle with the horizontal plane. The guide frame 401 and the cleaning plate 403 are both stainless steel components. The scraper 402, the fixing frame 404 and the springs 405 are all polyurethane rubber components.

[0038] The guide frame 401 and cleaning plate 403 of the stainless steel components have good smoothness, which reduces the adhesion of ferromagnetic impurities.

[0039] The scraper 402, the fixing frame 404, and the spring 405 of the polyurethane rubber component have high elasticity and wear resistance.

[0040] In this embodiment, when it is necessary to clean the scraper 402 and the cleaning plate 403, the fixing frame 404 is pulled away from the scraper 402 and the cleaning plate 403, and the scraper 402 and the cleaning plate 403 are pulled away from the guide frame 401, so that the scraper 402 and the cleaning plate 403 can be cleaned.

[0041] After cleaning, the cleaning plate 403 is placed on the surface of the positioning block 407, the surface of the scraper 402 is pressed against the surface of the limiting block 406, the two fixing brackets 404 are loosened, and the elastic force of the spring 405 pushes the fixing brackets 404 to move and lock into the cleaning plate 403 and the scraper 402.

[0042] like Figure 4 As shown, two limiting rods 408 are fixedly connected to one side of the fixing frame 404, and the surface of the limiting rods 408 is slidably connected to the inner wall of the guide frame 401.

[0043] Working principle: The scraper 402 scrapes large ferromagnetic impurities attached to the belt onto the inner bottom wall of the guide frame 401. The rotating brush roller 200 scrapes small ferromagnetic impurities on the belt onto the inner bottom wall of the guide frame 401, causing the ferromagnetic impurities in the guide frame 401 to slide into the iron collection frame. When the bristles on the brush roller 200 rotate and contact the comb-shaped cleaning plate 403, the cleaning plate 403 cleans the small ferromagnetic impurities attached to the bristles, keeping the bristles on the brush roller 200 clean.

[0044] It should be noted that the permanent magnet separator 100, brush roller 200 and first motor 300 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the permanent magnet separator 100 and the first motor 300 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
