Technical Field
[0001] This utility model relates to the field of magnetic separator cleaning technology, specifically an automatic cleaning device for a permanent magnet wet magnetic separator. Background Technology
[0002] The working principle of a permanent magnet wet magnetic separator is to separate magnetic materials from non-magnetic materials through the action of a magnetic field. After the permanent magnet wet magnetic separator has finished working, the inside of the machine needs to be cleaned, so an automatic cleaning device for permanent magnet wet magnetic separators is required.
[0003] A Chinese patent with publication number CN 219130075 U discloses a cleaning and flushing device for a magnetic separator, including a base, a water tank on top of the base, a first water pump movably connected to the top of the water tank, a first water pump movably connected to one end of the first water pump, and a first delivery pipe movably connected to the other end of the first water pump. This cleaning and flushing device for a magnetic separator is configured with a chute, a slider, a water collection box, a filter screen, a slot, a rotating shaft, a support frame, a water outlet pipe, and a second water pump. The water collection box is pulled out of the base and placed under the entire magnetic separator. High-pressure water jet cleaning is then performed using a spray gun. Even hard-to-reach crevices can be cleaned under high pressure. The cleaned water flows into the water collection box below the machine, is filtered by the filter screen, and the remaining water is reused for further cleaning. This design saves water for system purification and also reduces costs.
[0004] Existing automatic cleaning devices typically use water to rinse permanent magnet wet magnetic separators, but tailings tend to accumulate on the bottom plate of the machine. Since it is not convenient to clean the tailings accumulated at the bottom of the hopper, the device is not very easy to clean. Therefore, an automatic cleaning device for permanent magnet wet magnetic separators is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes an automatic cleaning device for a permanent magnet wet magnetic separator.
[0006] The technical solution adopted by this utility model to solve its technical problem is an automatic cleaning device for a permanent magnet wet magnetic separator, including a support frame, a receiving hopper mounted on the support frame, a control panel mounted on the outer wall of the receiving hopper, a stepper motor mounted on the outer wall of the receiving hopper via a base, a lead screw mounted on the output shaft of the stepper motor, the lead screw rotatably mounted on the inner wall of the receiving hopper, a guide rod fixedly mounted on the inner wall of the receiving hopper, a first slider sleeved around the lead screw, a second slider sleeved around the guide rod, scrapers fixedly mounted on the first and second sliders, and a feeding hopper mounted on the receiving hopper, with a feeding groove opened inside the feeding hopper. A discharge water pipe is fixedly installed on the top plate of the feed hopper, and a water inlet pipe is installed on the discharge water pipe. Multiple sets of nozzles are installed on the discharge water pipe. A slope is provided on the bottom plate of the receiving hopper. Water sprayed from the nozzles brushes the inner wall of the receiving hopper, causing the tailings to move to the bottom plate of the receiving hopper with the water flow. The tailings are discharged from the discharge hopper along the slope with the water flow. A stepper motor drives the lead screw to rotate, and the lead screw drives the first slider on it to move horizontally. The first slider drives the scraper to move horizontally. The scraper pushes the tailings accumulated on the bottom plate of the receiving hopper to the discharge port, and then discharges from the discharge hopper. This realizes convenient cleaning of tailings and helps to improve the convenience of cleaning the device.
[0007] Preferably, a discharge port is provided on the side wall of the receiving hopper, and a discharge hopper is installed at the discharge port on the side wall of the receiving hopper. An assembly groove is provided inside the side wall of the receiving hopper, and an electric telescopic rod is fixedly installed on the inner wall of the assembly groove. A push rod is installed on the electric telescopic rod, and a sealing plate is installed on the push rod. A drive motor is installed on the bracket via a base, and a roller is installed on the output shaft of the drive motor. A magnetic system is installed inside the roller, and the roller is rotatably installed on the side wall of the receiving hopper. A concentrate interception port is provided on the side wall of the receiving hopper, and a concentrate interception hopper is installed on the side wall of the receiving hopper. The operation of the electric telescopic rod is controlled by the control panel. The push rod on it drives the sealing plate to move vertically upward. When the sealing plate moves into the assembly groove, the discharge port opens. This structure has a large discharge port area, which allows the accumulated tailings to pass directly through, avoiding tailings blockage at the discharge port, which is beneficial to improving discharge efficiency and cleaning efficiency.
[0008] The advantages of this utility model are:
[0009] 1. This utility model uses water sprayed from a nozzle to brush the inner wall of the receiving hopper, causing the tailings to move with the water flow to the bottom plate of the receiving hopper. The tailings are then discharged from the discharge hopper along the slope with the water flow. A stepper motor drives a lead screw to rotate, which in turn drives a first slider to move horizontally. The first slider then drives a scraper to move horizontally, pushing the tailings accumulated on the bottom plate of the receiving hopper to the discharge port, where they are discharged. This achieves convenient cleaning of the tailings and improves the ease of cleaning the device.
[0010] 2. This utility model controls the operation of the electric telescopic rod through the control panel. The push rod on it drives the sealing plate to move vertically upward. When the sealing plate moves into the assembly slot, the discharge port opens. The discharge port area set by this structure is large, which can allow the accumulated tailings to pass through directly, avoiding tailings from clogging the discharge port, which is conducive to improving discharge efficiency and cleaning efficiency.

[0018] 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 scope of protection of the present utility model.
[0019] Please see Figure 1-3As shown, an automatic cleaning device for a permanent magnet wet magnetic separator includes a support 1, a receiving hopper 2 mounted on the support 1, a control panel 3 mounted on the outer wall of the receiving hopper 2, a stepper motor 4 mounted on the outer wall of the receiving hopper 2 via a base, a lead screw 5 mounted on the output shaft of the stepper motor 4, the lead screw 5 rotatably mounted on the inner wall of the receiving hopper 2, a guide rod 6 fixedly mounted on the inner wall of the receiving hopper 2, a first slider 7 sleeved around the lead screw 5, a second slider 8 sleeved around the guide rod 6, scrapers 9 fixedly mounted on the first slider 7 and the second slider 8, a feeding hopper 10 mounted on the receiving hopper 2, a feeding trough 11 opened inside the feeding hopper 10, a discharge water pipe 12 fixedly mounted on the top plate of the feeding hopper 10, a water inlet pipe 13 mounted on the discharge water pipe 12, multiple sets of nozzles 14 mounted on the discharge water pipe 12, and a ramp 25 provided on the bottom plate of the receiving hopper 2; Currently, existing automatic cleaning devices typically use water to rinse permanent magnet wet magnetic separators, but this easily leads to tailings accumulation on the bottom plate of the machine. Because it's difficult to easily clean the tailings accumulated at the bottom of the receiving hopper 2, the cleaning process is inconvenient. A new method addresses this by feeding slurry into the receiving hopper 2 from the feed trough 11 of the feed hopper 10. The slurry is then poured into the receiving hopper 2. A magnetic system is installed inside the drum 22, generating a magnetic field. Under the influence of this magnetic field, magnetic minerals in the slurry are adsorbed onto the drum 22. The drive motor 21 rotates the drum 22, causing the magnetic minerals adsorbed onto it to rotate to the concentrate receiving port 23. The magnetic minerals are scraped off by the receiving plate at the top of the concentrate receiving port 23 and then discharged from the concentrate receiving hopper 24, becoming concentrate. Non-magnetic minerals remain in the slurry, becoming tailings.
[0020] During the cleaning of receiving hopper 2, the discharge port 15 is opened, and water is introduced into the unloading water pipe 12 through the water inlet pipe 13. After entering the unloading water pipe 12, the water is sprayed out from each nozzle 14. The sprayed water brushes the inner wall of receiving hopper 2, causing the tailings to move to the bottom plate of receiving hopper 2 with the water flow. Since the bottom plate is provided with a slope 25, the tailings are discharged from the discharge hopper 16 along the slope 25 with the water flow. The stepper motor 4 drives the lead screw 5 to rotate, and the lead screw 5 drives the first slider 7 on it to move horizontally. The first slider 7 drives the scraper 9 to move horizontally. The scraper 9 pushes the tailings accumulated on the bottom plate of receiving hopper 2 to the discharge port 15, and then discharges from the discharge hopper 16. This realizes convenient cleaning of tailings and helps to improve the convenience of cleaning the device.
[0021] Please see Figure 4-5As shown, a discharge port 15 is provided on the side wall of the receiving hopper 2, and a discharge hopper 16 is installed at the discharge port 15 on the side wall of the receiving hopper 2. An assembly groove 17 is provided inside the side wall of the receiving hopper 2, and an electric telescopic rod 18 is fixedly installed on the inner wall of the assembly groove 17. A push rod 19 is installed on the electric telescopic rod 18, and a sealing plate 20 is installed on the push rod 19. A drive motor 21 is installed on the bracket 1 through a base, and a roller 22 is installed on the output shaft of the drive motor 21. A magnetic system is installed inside the roller 22, and the roller 22 is rotatably installed on the side wall of the receiving hopper 2. A concentrate intercepting port 23 is provided on the side wall of the receiving hopper 2, and a concentrate intercepting hopper is installed on the side wall of the receiving hopper 2. 24; During operation, the existing automatic cleaning device has a small tailings discharge port 15 area during the cleaning process of the permanent magnet wet magnetic separator, which easily causes tailings blockage, resulting in low discharge efficiency and affecting cleaning efficiency. By controlling the operation of the electric telescopic rod 18 through the control panel 3 during the cleaning of the docking hopper 2, the push rod 19 on it drives the sealing plate 20 to move vertically upward. The sealing plate 20 moves into the assembly groove 17, at which time the discharge port 15 opens. The discharge port 15 set by this structure has a larger area, which can allow the accumulated tailings to pass directly, avoiding tailings blockage at the discharge port 15, which is conducive to improving discharge efficiency and cleaning efficiency.
[0022] Working principle: Existing automatic cleaning devices typically use water to rinse permanent magnet wet magnetic separators, but tailings tend to accumulate on the bottom plate of the machine. Because it's difficult to easily clean the tailings accumulated at the bottom of the receiving hopper 2, the cleaning efficiency of the device is low. By feeding slurry into the feed trough 11 of the feed hopper 10 and pouring it into the receiving hopper 2, a magnetic system is installed inside the drum 22, generating a magnetic field. Under the influence of this magnetic field, magnetic minerals in the slurry are adsorbed onto the drum 22. Driven by the motor 21, the drum 22 rotates, and the magnetic minerals adsorbed on it rotate to the concentrate receiving port 23. The magnetic minerals are scraped off by the receiving plate at the top of the concentrate receiving port 23 and then discharged from the concentrate receiving hopper 24, becoming concentrate. Non-magnetic minerals remain in the slurry, becoming tailings. During the cleaning of receiving hopper 2, the discharge port 15 is opened, and water is introduced into the unloading water pipe 12 through the water inlet pipe 13. The water then sprays out from various nozzles 14, brushing the inner wall of receiving hopper 2. This causes the tailings to move with the water flow to the bottom plate of receiving hopper 2. Since the bottom plate has a ramp 25, the tailings are discharged from the discharge hopper 16 along the ramp 25. The stepper motor 4 operates, driving the lead screw 5 to rotate. The lead screw 5 drives the first slider 7 on it to move horizontally. The first slider 7 drives the scraper 9 to move horizontally, pushing the tailings accumulated on the bottom plate of receiving hopper 2 to the discharge port 15, and then discharging them from the discharge hopper 16. The present invention facilitates the cleaning of tailings, which is beneficial to improving the convenience of equipment cleaning. In the process of cleaning permanent magnet wet magnetic separators, the existing automatic cleaning device has a small tailings discharge port 15 area, which is prone to tailings blockage, resulting in low discharge efficiency and affecting cleaning efficiency. By controlling the operation of electric telescopic rod 18 through control panel 3 during cleaning of docking hopper 2, the push rod 19 on it drives the sealing plate 20 to move vertically upward. The sealing plate 20 moves into the assembly groove 17, at which time the discharge port 15 opens. The discharge port 15 with this structure has a larger area, which can allow the accumulated tailings to pass directly and avoid tailings blockage at the discharge port 15, which is beneficial to improving discharge efficiency and cleaning efficiency.
