[0001] The invention relates to the technical field of magnetic grinding mud recovery, in particular to a magnetic grinding mud auxiliary recovery device. Background Art

[0002] Magnetic grinding mud recovery is a process for recovering grinding mud containing magnetic particles. This recovery process mainly relies on the characteristics of magnetic particles in a magnetic field. Through specific equipment and methods, magnetic grinding mud is separated from the mixture or waste liquid to achieve resource reuse and environmental protection.

[0003] The Chinese patent with publication number CN111531468B proposes a magnetic grinding mud recovery device, including a wastewater pool and a treatment box located above the wastewater pool, one end of the treatment box is provided with a feed port, and the other end upper end outer wall is provided with a discharge port, and the side wall of the treatment box is provided with a mud scraper connected to the discharge port; the inner walls of the treatment box are all horizontally connected with a rotating shaft, the outer walls of multiple rotating shafts are wound with a synchronous belt, and the surface of the synchronous belt is provided with a plurality of permanent magnetic suction cups at intervals, the lower end of the treatment box is provided with a drainage pipe connected to the wastewater pool, the outer wall of the wastewater pool is provided with a water pump, and the water pump is provided with an inlet pipe connected to the wastewater pool and a water outlet pipe connected to the treatment box. The invention realizes the continuous discharge and real-time recovery of magnetic grinding mud slurry by providing a highly automated recovery device, and does not need to statically treat the grinding mud slurry, which greatly shortens the processing time of the grinding mud slurry, thereby improving the recovery efficiency of the grinding mud.

[0004] However, in actual production, the permanent magnetic suction cup only attracts the magnetic grinding mud within the effective range, and there is a magnetic blind spot. As a result, part of the mud can only be recovered by magnetic grinding mud through repeated cycles, which increases the ineffective process and recovery time. Therefore, the recovery efficiency of the magnetic grinding mud of this invention needs to be discussed. Summary of the invention

[0005] In order to overcome the shortcomings of existing devices that use intermittent permanent magnetic suction cups for magnetic grinding mud recovery, which have magnetic suction blind spots, cause part of the mud to be repeatedly circulated, and result in a longer time span, and fail to effectively improve the recovery efficiency of the magnetic grinding mud, the present invention provides a magnetic grinding mud auxiliary recovery device that improves the magnetic suction efficiency through vibration.

[0006] A magnetic grinding mud auxiliary recovery device comprises a treatment box, a waste liquid box, a feeding channel, a conveying platform, a conveyor belt, a strip permanent magnet block and a guide plate. The bottom of the treatment box is connected to the waste liquid box, the conveying platform is arranged in the inner cavity of the treatment box, the conveying platform is equipped with a conveyor belt, and the conveyor belt is equidistantly arranged with strip permanent magnet blocks. The feeding channel is fixed to the treatment box and guides the conveyor belt. The guide plate is fixedly connected to the treatment box and docks with the conveyor belt. The guide plate is equipped with a discharge pipe and also comprises a protrusion, a wedge block and a circulation mechanism. The conveying platform is fixedly connected with a protrusion, and the inner side of the conveyor belt is provided with a wedge block. The protrusion can contact and push the wedge block to move. The conveying platform is arranged in an inclined shape. After the mud is guided to the conveyor belt, it can flow, thereby increasing the contact area between the mud and the strip permanent magnet block. During the rotation of the conveyor belt, the protrusion continuously pushes the wedge block to form vibration, so that the conveyor belt shakes. The strip permanent magnet blocks on the surface of the conveyor belt will attract the magnetic grinding mud in the mud, and the mud falls into the waste liquid box and is guided back to the feeding channel through the circulation mechanism for circulation recovery.

[0007] A more excellent improvement scheme is that the circulation mechanism includes a circulation pipeline and a pump, the circulation pipeline is connected between the processing box and the waste liquid box, and the pump is arranged in the circulation pipeline.

[0008] A more excellent improvement scheme is that the material guide plate is provided with a recessed portion, and the recessed portion is connected to the discharge pipe.

[0009] A more excellent improvement scheme is to further include a drain valve, which is arranged in the circulation pipeline, specifically in the circulation pipeline at the water inlet end of the pump.

[0010] A more excellent improvement scheme is to also include a spraying mechanism for removing excess mud, the spraying mechanism includes a water tank, a water pipe and an atomizing nozzle, the water tank is fixed on the side of the processing box, the water tank is connected to the atomizing nozzle through the water pipe, and the atomizing nozzle points to the conveyor belt.

[0011] A more excellent improvement scheme is to further include a scraper plate and a gear set, wherein the scraper plate is rotatably connected to the material guide plate, and the conveying platform drives the scraper plate through the gear set.

[0012] A more excellent improvement scheme is that the scraper is provided with a scraper made of rubber material, and the scraper is provided with a scraping groove which is embedded in the strip permanent magnetic block and scrapes the material therefrom.

When the conveyor platform rotates, it can drive the small gear to rotate rapidly.

[0014] The beneficial effects of the present invention are as follows: 1. An inclined conveying platform is provided. During the rotation of the conveyor belt, the mud falling on the conveyor belt can flow under the action of gravity, thereby increasing the contact area between the magnetic grinding mud and the bar permanent magnet block, and then improving the magnetic attraction efficiency of the bar permanent magnet block, reducing the time span, and the wedge blocks on the inner side of the conveyor belt will be continuously pushed by the protrusions, thereby causing slight vibrations to the conveyor belt, further improving the magnetic attraction effect of the bar permanent magnets on the conveyor belt, so as to improve the recovery efficiency of the magnetic grinding mud. A circulation component is provided to circulate the mud that has completed magnetic attraction, further improving the recovery rate of the magnetic grinding mud.

DETAILED DESCRIPTION

[0026] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0028] Embodiment: A magnetic grinding mud auxiliary recovery device, such as Figure 1-Figure 6 As shown, it includes a processing box 1, a waste liquid box 2, a feeding channel 3, a conveying platform 4, a conveyor belt 5, a strip permanent magnet block 501 and a guide plate 6. The bottom of the processing box 1 is connected to the waste liquid box 2. The conveying platform 4 is arranged in the inner cavity of the processing box 1. The conveying platform 4 is equipped with a conveyor belt 5. The strip permanent magnet blocks 501 are equidistantly arranged on the conveyor belt 5. The feeding channel 3 is fixed to the processing box 1 and guides the conveyor belt 5. The guide plate 6 is fixedly connected to the processing box 1 and docks with the conveyor belt 5. The feeding channel 3 is located below the guide plate 6. The guide plate 6 is provided with a recessed portion, and the recessed portion is connected to the discharge pipe 7. It also includes a convex block 8, a wedge block 9 and a circulation mechanism. The conveying platform 4 is fixedly connected with the convex block 8. A wedge block 9 is provided on the inner side of the conveyor belt 5, and the protrusion 8 can contact and push the wedge block 9 to move. The conveying platform 4 is set to be inclined 50 degrees to the left. After the mud is guided to the conveyor belt 5, it can flow, thereby increasing the contact area between the mud and the strip permanent magnet block 501. During the rotation of the conveyor belt 5, the protrusion 8 continuously pushes the wedge block 9 to form vibration, causing the conveyor belt 5 to shake. The strip permanent magnet block 501 on the surface of the conveyor belt 5 will attract the magnetic grinding mud in the mud, so that after the mud falls on the conveyor belt 5, the magnetic grinding mud mixed in it can be fully adsorbed by the strip permanent magnet block 501. The mud falls into the waste liquid tank 2 and is guided back to the feed channel 3 through the circulation mechanism for recycling.

[0029] like Figure 5 and Figure 6As shown, the circulation mechanism includes a circulation pipe 10 and a pump 11 . The circulation pipe 10 is connected between the treatment box 1 and the waste liquid box 2 . The pump 11 is arranged in the circulation pipe 10 .

[0030] like Figure 6 As shown, a drain valve 12 is also included. The drain valve 12 is arranged in the circulation pipe 10, specifically in the circulation pipe 10 at the water inlet end of the pump 11. After the magnetic grinding mud in the mud is completely absorbed, the mud in the waste liquid tank 2 can be discharged by opening the drain valve 12.

[0031] like Figure 7 As shown, a spraying mechanism for removing excess mud is also included, and the spraying mechanism includes a water tank 13, a water pipe 14 and an atomizing nozzle 15. The water tank 13 is fixed to the rear side of the processing box 1, and the water tank 13 is connected to the atomizing nozzle 15 through the water pipe 14, and the atomizing nozzle 15 points to the conveyor belt 5.

[0032] like Figure 8 As shown, it also includes a scraper plate 16 and a gear set 17. The scraper plate 16 is rotatably connected to the guide plate 6. The conveying platform 4 drives the scraper plate 16 through the gear set 17. The scraper plate 16 is provided with a rubber scraper. The scraper plate is provided with a scraper groove that is embedded in the bar permanent magnet block 501 and scrapes the material thereon. The gear set 17 is a speed-increasing gear set, that is, the gear set 17 is composed of large and small gears that mesh with each other, wherein the large gear is connected to the end of the rotating shaft of the conveying platform 4 by a key, and the small gear is fixed to the end of the scraper plate 16 by a key. When the conveying platform 4 rotates, it can drive the small gear to rotate rapidly. The scraper plate 16 can form a speed difference with the conveyor belt 5, so that the magnetic grinding mud on the surface of the conveyor belt 5 can be swept off.

[0033] The working principle of the embodiment of the present invention is as follows: a motor is arranged inside the conveying platform 4. Turning on the motor can drive the conveyor belt 5 to rotate clockwise. The conveying platform 4 is set to an inclined state with an inclination angle of 50 degrees. The mud is guided from the feed channel 3 to the surface of the conveyor belt 5. While the motor drives the conveyor belt 5 to rotate clockwise, the mud flows downward under the action of gravity, which effectively increases the contact area between the magnetic grinding mud in the mud and the bar permanent magnet. At the same time, the wedge block 9 on the inner side of the conveyor belt 5 will continue to be pushed by the protrusion 8, thereby causing a slight vibration to the conveyor belt 5, further improving the magnetic attraction effect of the bar permanent magnet on the conveyor belt 5. When the mud rotates to the lower end of the conveying platform 4, it flows into the waste liquid tank 2, and the bar permanent magnet continues to rotate clockwise with the conveyor belt 5 with the magnetic grinding mud attracted by it. A water pump is arranged at the bottom of the water pipe 14, and the water pump pumps the clean water in the water tank 13 to the atomizing nozzle 15. The atomizing nozzle 1 5 is located on the left side of the conveying platform 4, and the atomizing nozzle 15 will spray the strip permanent magnet block 501 externally, so as to remove the mud attached to the surface of the strip permanent magnet block 501. After the strip permanent magnet block 501 rotates to the right side of the conveying platform 4 with the conveyor belt 5, the guide plate 6 will scrape off the magnetic grinding mud magnetically attracted on the surface of the strip permanent magnet block 501. When the conveying platform 4 rotates, it can drive the pinion to rotate rapidly, that is, the scraper plate 16 rotates rapidly. The scraper plate 16 is provided with a scraper made of rubber. The scraper plate is provided with a scraper groove that is embedded in the strip permanent magnet block 501 and scrapes the material therefrom. The scraper plate 16 can efficiently sweep off the grinding mud of the strip permanent magnet block 501. After the magnetic grinding mud enters the guide plate 6, it is discharged by the discharge pipe 7. There is still a very small part of the magnetic grinding mud in the mud that falls into the waste liquid tank 2. Therefore, the pump 11 can be turned on to pump the mud in the waste liquid tank 2 into the feed channel 3 for recycling.

[0034] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
