Description

Technical Field

[0001] The invention relates to the technical field of filter pressing and purification, in particular to diamond wastewater secondary filter pressing equipment and its application in diamond purification. Background Art

[0002] A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to an object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgy, dye, food, brewing, ceramics and environmental protection industries.

[0003] Chinese invention patent CN111450587B discloses a wastewater treatment filter press, which includes a jack, a compression plate, a body, a feed hopper, a filter cloth, an anti-accumulation mechanism, and a water outlet pipe. The output end of the jack is fixed to the compression plate, which is installed inside the body. The upper end of the body is provided with a feed hopper and is connected to the feed hopper. Wastewater is discharged into the body through the feed hopper. The filter press has low filtration efficiency and poor filtration effect.

[0004] Patent application CN118987725A relates to the field of sewage treatment, specifically to an industrial wastewater filter press treatment equipment, including a mounting base, a sewage trough, a mesh plate, a lifting hydraulic rod, a connecting arm, an extrusion frame, a sewage pipe, a hanger, an extrusion device and a push-sweep device, wherein the sewage pipe and the extrusion frame are connected; the push-sweep device includes a drive motor, a screw, a limit rod, a push block and a scraper; the filter press is difficult to operate and has low operating precision.

[0005] If the wastewater is not evenly spread when the filter press is in use, the filtration speed of the wastewater in the thicker area will be much slower than that in the thinner area during the filtration process. Due to the uneven distribution of the wastewater, the collected clean water contains more impurities and cannot meet the expected filtration quality standards, affecting the subsequent use of water resources.

[0006] In addition, blockage occurs during the paving process of the diamond waste water. The existing technologies lack the ability to quickly clear the blockage, which affects the stability of the diamond waste water flow and causes the liquid level of the diamond waste water to continue to rise and overflow.

[0007] At the same time, when the amount of diamond wastewater changes, it will not only affect the subsequent paving quality, but also cause excessive impurities to adhere to the surface of the filter cloth, thereby affecting the subsequent diamond wastewater filtration effect.

[0043] The filter cloth cleaning assembly 17 also includes a servo motor 1701, and the power output shaft of the servo motor 1701 is connected to the rotating shaft 1703 through a coupling.

A magnetic mounting plate 1713 is provided at the bottom output end of the second electric-controlled push rod 1708. The second electric-controlled push rod 1708 is started and drives the magnetic mounting plate 1713 to move up and down.

The clean water inside the connecting pipe 1709 enters the water spray pipe 1711 along the hydraulic water flow transfer box 1710 and sprays above the upper filter press cloth 8.

[0046] Specifically, during cleaning, the servo motor 1701 is started to drive the rotating shaft 1703 to rotate, the rotating shaft 1703 drives the rotating plate 1704 to rotate, and the rotating plate 1704 causes the sliding shaft 1705 to reciprocate up and down in the internal circular hole, thereby causing the swinging member 1706 to swing with the movable rod 1707 as the axis, and the swinging member 1706 drives the second electric control push rod 1708 to move left and right, and the second electric control push rod 1708 drives multiple water pressure water flow transfer boxes 1710 to move left and right synchronously through the magnetic mounting plate 1713.

[0047] During use: When the secondary filter press equipment for diamond wastewater is working, the paving plate 413 in the uniform paving assembly 4 distributes the wastewater evenly under the action of the buffer spring 411, and at the same time the first electric control push rod 415 starts and drives the fixed plate 414 to move downward to a suitable position, the fixed plate 414 drives the lower connecting plate 412 to move downward to a suitable position through the slide plate 408 and the sliding plate 407, the connecting plate 412 drives the paving plate 413 to move downward to a suitable position, and at the same time the driving motor 401 starts and rotates forward, the driving motor 401 drives the rotating rod 403 to rotate to the initial angle, the rotating rod 403 drives the pulling rope 405 to rotate through the rotating reel 404 and drives the sliding plate 407 to move along the slide plate 408 to a suitable position, the wastewater is poured into the wastewater filling station 2, and the liquid level sensor 419 detects the liquid level value above the wastewater filling station 2.

[0048] The auxiliary rotating rod 9 cooperates with the arc-shaped gear plate 10 to separate the upper filter cloth 8 and the lower filter cloth 11. The wastewater enters the middle of the upper filter cloth 8 and the lower filter cloth 11, and then the rotating cylinder 12 merges the two. The electric rotating roller 13 is started to start the filtration process, which facilitates the filtration operation. The clean water filtered out flows into the clean water collection box 14, and the residue remains on the lower filter cloth 11 and finally falls into the residue placement box 16. When the filter cloth is cleaned, the water pump 19 sends the clean water through the hydraulic pipe 1712 and the connecting pipe 1709 to the hydraulic water flow transfer box 1710, and then sprays it out through the water spray pipe 1711 to clean the upper filter cloth 8 above.

[0049] The servo motor 1701 starts and drives the rotating shaft 1703 to rotate, the output end of the second electric control push rod 1708 extends to the initial position, the rotating shaft 1703 drives the swinging member 1706 to swing back and forth continuously through the rotating plate 1704 and the sliding shaft 1705, the swinging member 1706 drives the magnetic mounting plate 1713 to swing back and forth through the movable rod 1707 and the second electric control push rod 1708, the magnetic mounting plate 1713 drives the water spray pipe 1711 to swing back and forth through the water pressure water flow transfer box 1710, and the water spray pipe 1711 cleans the upper part of the filter press cloth 8.

[0050] At the same time, the magnetic mounting plate 1713 reciprocates and the distance between the magnetic follower plate 418 is constantly changing. When the magnetic mounting plate 1713 swings toward the end of the magnetic follower plate 418, the distance between the magnetic mounting plate 1713 and the magnetic follower plate 418 is reduced and the magnetic repulsion force is increased. Under the action of the magnetic repulsion force, the magnetic follower plate 418 drives the sliding plate 407 to squeeze the compression spring 416 along the slide plate 408 and move away from the U-shaped seat 1702. When the magnetic mounting plate 1713 moves away from the magnetic follower plate 418, the distance between the magnetic mounting plate 1713 and the magnetic follower plate 418 is reduced and the magnetic repulsion force is increased. When the end 8 swings, the distance between the magnetic mounting plate 1713 and the magnetic follower plate 418 increases and the magnetic repulsion force decreases. The sliding plate 407 drives the magnetic follower plate 418 to move closer to the U-shaped seat 1702 end under the elastic force of the compression spring 416. The sliding plate 407 synchronously drives the connecting plate 412 and the flat plate 413 below to swing back and forth above the wastewater filling table 2, further improving the scraping and cleaning effect above the wastewater filling table 2, and improving the flow stability and unblocking of the diamond wastewater above the wastewater filling table 2.

[0051] When the amount of diamond wastewater above the wastewater filling table 2 increases, the liquid level value detected by the liquid level sensor 419 increases. At this time, there are two situations that will cause the liquid level to rise. One is that blockage occurs between the flat plate 413 and the wastewater filling table 2, and the other is that the gap between the flat plate 413 and the wastewater filling table 2 is too small.

[0052] When the liquid level value detected by the liquid level sensor 419 increases, the drive motor 401 starts and rotates in the reverse direction. The drive motor 401 drives the rotating rod 403 to rotate in the reverse direction. The rotating rod 403 drives the rotating reel 404 to rotate in the reverse direction. The rotating reel 404 drives the pulling rope 405 to rotate in the reverse direction. The pulling force applied by the pulling rope 405 on the sliding plate 407 is reduced. Under the elastic force of the compression spring 416, the sliding plate 407 is driven to move along the slide plate 408 toward the end of the U-shaped seat 1702. The sliding plate 407 drives the flat plate 413 to move through the connecting plate 412. The flat plate 413 applies a reverse thrust to the wastewater above the wastewater filling station 2, thereby improving the scraping and cleaning of impurities stuck between the flat plate 413 and the wastewater filling station 2, thereby ensuring the fluidity of the subsequent diamond wastewater.

[0053] At the same time, when the sliding plate 407 drives the magnetic follower plate 418 to move closer to the U-shaped seat 1702 end, when the magnetic mounting plate 1713 swings to the side close to the magnetic follower plate 418, the distance between the magnetic mounting plate 1713 and the magnetic follower plate 418 decreases and the magnetism increases. Then, the magnetic follower plate 418 drives the sliding plate 407 to squeeze the compression spring 416 and move the distance increased under the magnetic repulsive force of the magnetic mounting plate 1713. When the magnetic mounting plate 1713 continues to rotate in the opposite direction, the compression spring 416 is elastically released. Under the action of force, the reverse reset distance of the sliding plate 407 is increased, and then the reciprocating swing amplitude of the flattening plate 413 above the wastewater filling table 2 is increased through the connecting plate 412, and the position change of the flattening plate 413 above the wastewater filling table 2 is coordinated to further achieve the scraping and cleaning effect of the impurities blocked between the wastewater filling table 2 and the flattening plate 413, with stronger dredging and higher adaptability, thereby ensuring that the amount of diamond wastewater inside the wastewater filling table 2 gradually decreases, and the liquid level value detected by the liquid level sensor 419 gradually decreases.

[0054] However, when the sliding plate 407 drives the tiling plate 413 to move in the opposite direction to the maximum distance through the connecting plate 412, the liquid level value detected by the liquid level sensor 419 is still greater than the set liquid level preset value. At this time, it means that the distance between the tiling plate 413 and the wastewater filling station 2 is too small, and the normal discharge rate of the diamond wastewater above the wastewater filling station 2 cannot be guaranteed. Then the first electric-controlled push rod 415 is started and the output end is extended. The first electric-controlled push rod 415 drives the fixed plate 414 to move upward, and the fixed plate 414 drives the slide plate 408 to move upward. The slide plate 408 drives the sliding plate 407 to move upward. The sliding plate 407 drives the tiling plate 413 to move upward through the connecting plate 412. The gap between the bottom of the tiling plate 413 and the top of the wastewater filling station 2 increases. The diamond wastewater above the wastewater filling station 2 is filtered by the tiling plate 413, and the amount of wastewater reaching the top of the filter press body 1 increases, thereby ensuring the stable flow and filtration of the diamond wastewater.

[0055] And since the amount of diamond wastewater above the filter press body 1 increases, the amount of impurities adhered to the upper filter cloth 8 increases accordingly. At this time, the second electric control push rod 1708 is started and the output end is extended. The output end at the bottom of the second electric control push rod 1708 drives the magnetic mounting plate 1713 to move downward, and the magnetic mounting plate 1713 drives multiple water pipes 1711 to move downward. The gap between the bottom of the water pipe 1711 and the upper filter cloth 8 is reduced, and the clean water sprayed by the water pipe 1711 enhances the spraying and flushing efficiency of the upper filter cloth 8, thereby ensuring the subsequent transmission and filtration effect of the upper filter cloth 8.

[0056] At the same time, since the magnetic mounting plate 1713 moves downward, the movable rod 1707 drives the magnetic mounting plate 1713 to increase its swinging distance to both sides through the second electric-controlled push rod 1708, and the magnetic repulsive force exerted by the magnetic mounting plate 1713 and the magnetic follower plate 418 increases during the lateral reciprocating swing process, and then drives the sliding plate 407 to swing back and forth inside the slide plate 408 through the magnetic follower plate 418. The sliding plate 407 drives the flat plate 413 to swing back and forth above the wastewater filling station 2 through the connecting plate 412, effectively improving the lateral reciprocating scraping and cleaning effect when the amount of wastewater above the wastewater filling station 2 increases, ensuring the stability and passability of the subsequent flow of diamond wastewater on the wastewater filling station 2, and having stronger adaptability.

[0057] After adjusting the gap between the bottom of the paving plate 413 and the wastewater filling table 2, the amount of diamond wastewater above the wastewater filling table 2 gradually decreases, and the liquid level value detected by the liquid level sensor 419 gradually decreases. At this time, the driving motor 401 starts and drives the rotating rod 403 to rotate. The rotating rod 403 applies tension to the pulling rope 405 by rotating the reel 404. The pulling rope 405 drives the sliding plate 407 to squeeze the compression spring 416 inside the slide plate 408 and move toward the end of the raw material U-shaped seat 1702. The sliding plate 407 drives the paving plate 413 to move to the initial position through the connecting plate 412. The above process is repeated continuously and the subsequent diamond wastewater is filtered, paved and pressed.
