[0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. It can improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture, or reduce the unit cement consumption. The production process of water reducer requires the use of naphthalene mother liquor obtained after the neutralization reaction, but the naphthalene mother liquor contains some impurities, so the mother liquor needs to be filtered and purified after preparation.

[0003] In the prior art, when the water reducer mother liquor is filtered and purified, the water reducer mother liquor is generally filtered and purified through a filter screen. When the water reducer mother liquor is filtered through the filter screen, the filtered mother liquor flows away from the surface of the filter screen, while the solid impurities filtered in the mother liquor remain on the surface of the filter screen. In order to avoid the impurities on the filter screen from gradually accumulating during purification, which slows down the filtration speed of the filter screen, after filtering the water reducer mother liquor, the filter screen needs to be manually disassembled and the solid impurities on the surface of the filter screen need to be cleaned, thereby increasing the workload of the staff and reducing the efficiency of the mother liquor filtration and purification.

[0025] The utility model provides Figure 1-4 The water reducing agent mother liquor filtration and purification production device shown comprises:

[0026] A box body 1, wherein a top cover 2 is provided on the top of the box body 1 and a feed hopper 3 is provided at the center of the top of the top cover 2;

[0027] A filter plate 4 is arranged in the box body 1 and is used to filter the water reducer mother liquor in the box body 1. A first cylinder 5 is arranged on one side of the box body 1. The piston rod of the first cylinder 5 is movably penetrates the box body 1 and is connected to the brush plate 6. A collecting component 7 for collecting filter residues is arranged on one side of the box body 1. The filter residues brushed by the brush plate 6 are collected by the collecting box 8 of the collecting component 7, so that the filter residues can be brushed into the collecting box 8 for easy cleaning later.

[0028] The collecting assembly 7 includes a sealing plate 9 and a drain plate 10. The sealing plate 9 is slidably connected to the sealing grooves 11 provided on both sides of the collecting box 8, and a sealing gasket 12 is provided in the sealing groove 11. The sealing gasket 12 strengthens the sealing performance of the sealing plate 9 and the sealing groove 11 after being plugged in.

[0029] One end of the collecting box 8 away from the sealing plate 9 is connected to the casing 1, and the drain plate 10 is arranged at the bottom of the collecting box 8. A liquid collecting trough 13 is arranged in the collecting box 8 and at the bottom of the drain plate 10, and the liquid collecting trough 13 is connected to the casing 1. The water reducer mother liquor remaining in the solid impurities is drained through the drain plate 10, and the drained water reducer mother liquor can flow into the liquid collecting trough 13 through the drain plate 10, and then flow into the casing 1 from the liquid collecting trough 13, thereby avoiding waste of the water reducer mother liquor.

[0030] One end of the sealing plate 9 is provided with two groups of latch holes 14 , and the surface of the collecting box 8 is provided with latches 15 , which are matched and plugged with the latch holes 14 , and the two groups of latch holes 14 are respectively provided at the top and bottom of the sealing plate 9 .

[0031] A water tank 16 and a water pump 17 are provided on the surface of the top cover 2. The water pump 17 is connected to the water tank 16 through a water pipe 18. The other end of the water pump 17 is connected to a water storage shell 20 provided on the top of the brush plate 6 through a hose 19. The water pump 17 draws the clean water in the water tank 16 into the hose 19 through the water pipe 18, and then flows from the hose 19 into the water storage shell 20. The hose 19 located in the box body 1 is reserved with sufficient length so that when the brush plate 6 moves, the hose 19 can move with the brush plate 6.

[0032] The surface of the brush plate 6 is provided with a plurality of water outlet holes 21 , and one end of the water outlet hole 21 is connected to the water storage shell 20 , so that the surface of the filter plate 4 is cleaned by the clean water flowing out of the water outlet hole 21 .

[0033] Two sets of guide rods 22 are provided in the box body 1, and the two ends of the brush plate 6 are slidably sleeved on the surface of the guide rods 22. When the first cylinder 5 pushes the brush plate 6 to move, the two ends of the brush plate 6 slide on the surface of the guide rods 22, thereby enhancing the stability of the movement of the brush plate 6 through the guide rods 22.

[0034] The water reducer mother liquor filtering and purification production device pours the water reducer mother liquor into a feed hopper 3, and flows through the feed hopper 3 to the surface of a filter plate 4 in a housing 1, filters the water reducer mother liquor through the filter plate 4, and the filtered water reducer mother liquor flows into the bottom of the housing 1, and the filtered solid impurities remain on the surface of the filter plate 4. By starting the first anti-corrosion diving cylinder 5 to work, the piston rod of the first cylinder 5 drives the brush plate 6 to move back and forth on the surface of the filter plate 4. While moving, the brush at the bottom of the brush plate 6 brushes the solid impurities accumulated on the surface of the filter plate 4 to avoid the accumulation of solid impurities and affect the filtering speed of the water reducer mother liquor, thereby maintaining a good filtering effect during the filtering and purification of the water reducer mother liquor, and the water reducer mother liquor after filtering and purifying from the surface of the filter plate 4 can flow to the bottom of the housing 1 and be directly discharged through the discharge pipe 23 at the bottom of the housing 1.

[0035] When the brush plate 6 is driven by the piston rod of the first cylinder 5 to move back and forth on the surface of the filter plate 4 to brush the solid impurities, the accumulated solid impurities can be pushed into the collection box 8 by the brush at the bottom of the brush plate 6, so that the solid impurities can be collected to avoid the accumulation or dispersion of the solid impurities on the surface of the filter plate 4 affecting the filtering speed, and the solid impurities pushed into the collection box 8 are located on the surface of the drain plate 10, so that the water reducer mother liquor remaining in the solid impurities can be drained through the drain plate 10, and the drained water reducer mother liquor can flow into the liquid collecting tank 13 through the drain plate 10, and then flow into the box body 1 from the liquid collecting tank 13, so as to avoid wasting the water reducer mother liquor;

[0036] After the filtration and purification of the water reducer mother liquor is completed, the solid impurities pushed into the collecting box 8 can be removed by pulling out the pin 15 in the pin hole 14 at the top of the sealing plate 9 and pulling the sealing plate 9 upward. After the sealing plate 9 is pulled to a certain height, the pin 15 is inserted into the pin hole 14 at the bottom of the sealing plate 9, thereby limiting the sealing plate 9, so that the collecting box 8 is in an open state, and the solid impurities in the collecting box 8 can be cleaned, which makes it more convenient to concentrate in the later stage and avoids the problem of needing to disassemble the filter screen for cleaning, thereby greatly improving the efficiency of filtration and purification of the mother liquor.

[0037] After the solid impurities are cleaned, the water pump 17 can be started to work. The water pump 17 pumps the clean water in the water tank 16 into the hose 19 through the water pipe 18, and then flows into the water storage shell 20 from the hose 19. At this time, the first cylinder 5 is started to work, and the first cylinder 5 drives the brush plate 6 to brush the surface of the filter plate 4, and the clean water in the water storage shell 20 flows out through the water outlet 21. While the brush plate 6 moves, the clean water flowing out of the water outlet 21 cleans the surface of the filter plate 4 to remove the solid impurities remaining on the surface of the filter plate 4. The clean water after cleaning flows to the bottom of the box body 1 and is discharged from the discharge pipe 23 at the bottom of the box body 1. The filter plate 4 can be cleaned by flushing the filter plate 4 with clean water, so as to avoid the corrosion of the filter plate 4 and the box body 1 by solid impurities. By cleaning the filter plate 4 and the box body 1, the filter plate 4 and the box body 1 are made cleaner, and cross contamination with the next batch of water reducer mother liquor is avoided, so as to make the subsequent water reducer mother liquor filtering and purification effect better.

[0038] While cleaning the filter plate 4, the second cylinder 25 located at the bottom center of the filter plate 4 can be started to work. The second cylinder 25 is installed on a cross bar (not shown in the figure) facing into the box body 1 and located below the movable filter plate 4, so that the second cylinder 25 is located at the bottom center of the filter plate 4. The cross bar is parallel to the guide rod 22 in the vertical plane and perpendicular to the horizontal plane. The piston rod of the second cylinder 25 retracts, driving the dredging frame 24 to move in the direction close to the filter plate 4. When the dredging frame 24 moves, the two sides slide on the inner wall of the box body 1 through short blocks, and the dredging frame 24 moves toward the filter plate 4. When the dredging frame 24 moves in the same direction, a number of evenly distributed ejectors 26 on the surface of the dredging frame 24 are inserted into the mesh holes 27 on the surface of the filter plate 4, so that the solid impurities blocked in the mesh holes 27 on the surface of the filter plate 4 are dredged by the ejectors 26, so that the dredging frame 24 can be driven by the second cylinder 25 to reciprocate up and down, and the solid impurities blocked in the mesh holes 27 are pushed up and down in the mesh holes by the ejectors 26. When the solid impurities blocked in the mesh holes 27 are pushed to the top of the filter plate 4, the ejected solid impurities can be brushed and cleaned by the brush plate 6 to the collection box 8 for collection, which is convenient for centralized cleaning at a later time.
