Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and in particular relates to a mineral processing return water pool shared by filtering and pressing. Background Art

[0002] Sludge is a solid precipitate produced by the water and sewage treatment process. In the production process, most mines use filter press dehydration operations, and the filtered water is collected through pipes into the return water tank for recycling. After the return water in the return water tank is repeatedly recycled, more and more sludge will be deposited in the return water tank, especially in the dehydration process of the mineral processing plant involving a large amount of fine particles or a large amount of mud, the amount of sludge deposited in the return water tank is even more alarming.

[0003] In the prior art, the filter press equipment is placed above the water pool, and the filter blocks are not convenient to clean directly after filtration. In addition, since the filter press water is directly discharged into the water pool without being filtered again, the amount of sludge precipitation in the water pool will be further increased, making it difficult to clean.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0025] The above-mentioned filter press plates 10, starting from the first filter press plate, are the first filter press plate 22, the second filter press plate 23, the third filter press plate 24, the fourth filter press plate 25, the fifth filter press plate 26, the sixth filter press plate 27, the seventh filter press plate 28, the eighth filter press plate 29, and the ninth filter press plate 30.

[0026] The utility model is divided into three movement processes when in use, the first process is the squeezing movement, the second process is the transporting movement, and the third process is the resetting movement, and the three movements are performed in sequence.

[0027] The first process: when in use, since the first fixed plate 2 is fixedly mounted with the first oil cylinder 3 at one end, and the output end of the first oil cylinder 3 is fixedly mounted with the first pressing plate 4, and the first rotating wheels 5 are fixedly mounted on both sides of the first pressing plate 4, when the first oil cylinder 3 is started, the first oil cylinder 3 drives the first pressing plate 4 to make a linear motion relative to the first pressing plate 4 around the central axis of the first oil cylinder 3, thereby driving the first rotating wheel 5 to rotate around its central axis in a direction away from one end of the first fixed plate, and since there are a number of gravity clamps between the second pressing plate 9 and the first pressing plate 4, the second pressing plate 9 and the first pressing plate 4 are connected to the support plate 6. The first filter press plate 22 on the upper surface, and then the first pressure plate 4 squeezes the first filter press plate 22, so that the first filter press plate 22 is in a linear motion state relative to the first fixed plate 2. Since there are a number of filter press plates 10 connected to the upper surface of the support plate 6 by gravity between the second pressure plate 9 and the first pressure plate 4, the output end of the second oil cylinder 8 is fixedly installed on one end of the second pressure plate 9. When the second oil cylinder is started, it drives the second pressure plate 9 to squeeze the ninth filter press plate 30, so that the ninth filter press plate 30 moves linearly toward the first pressure plate 4, thereby completing the overall squeezing process of the filter press plate 10.

[0028] The second process: when in use, since the first pressure plate 4 is fixedly connected to the output shaft of the first oil cylinder 3, and there are a number of filter press plates 10 clamped by gravity on the upper surface of the support plate 6 between the first pressure plate 4 and the first pressure plate 4, when the first oil cylinder 3 starts and the second oil cylinder 8 stops, the output shaft of the first oil cylinder 3 drives the first pressure plate 4 to squeeze the filter press plate 10 through the first rotating wheel 5 fixedly installed on both sides of the first pressure plate 4, thereby driving the filter press plate 10 to make a branch line movement in the direction of the second pressure plate 9, thereby completing the overall transportation process of the filter press plate 10 to the outside of the return water tank 1.

[0029] The third process: when in use, since the second pressure plate 9 is fixedly connected to the output shaft of the second oil cylinder, and there are a number of filter press plates 10 clamped by gravity on the upper surface of the support plate 6 between the second pressure plate 9 and the first pressure plate 4, when the first oil cylinder stops and the second oil cylinder starts, the second oil cylinder drives the second pressure plate 9 to squeeze the filter press plate 10 through the second rotating wheels 21 fixedly installed on both sides of the second pressure plate 9, thereby driving the filter press plate 10 as a whole to make a linear motion in the direction of the first pressure plate 4, and then completing the overall reset of the filter press plate 10 to the top of the return water tank 1.

[0030] The utility model completes the operation through three movement processes. In the first movement process, the first oil cylinder 3 and the second oil cylinder 8 are driven at the same time, driving the first pressure plate 4 and the second pressure plate 9 to squeeze the filter press plate 10, so that the filter press plates 10 can be evenly stressed, so that the squeezed water flows into the return water tank 1. In the second movement process, the first oil cylinder 3 starts and the second oil cylinder 8 stops, so that the filter press plate 10 is only subjected to the thrust from the first oil cylinder 3 and moves linearly in the direction of the second oil cylinder 8, so that the filter press plate 10 can be transported to the outside of the return water tank 1 as a whole, which is convenient for the centralized collection and transportation of mud blocks after filtration, thereby solving the problem that the filter press equipment is placed above the water tank and the filter blocks after filtration are not convenient to be directly cleaned.

[0031] In one embodiment, for the above-mentioned feed hole, the filter press plate 10 is provided with an inclined groove 11 on both the front and back sides, a plurality of support columns 12 are fixedly installed on the bottom of the inclined groove 11, and a feed hole 13 is provided at the intersection of the inner wall of the inclined groove 11 and the front side of the filter press plate 10.

[0032] During use, since the filter press plate 10 is provided with an inclined groove 11 on both sides, when sludge enters, the sludge will enter the inclined groove 11 through the introduction hole 13 provided at the intersection of the inner wall of the inclined groove 11 and the front side of the filter press plate 10. Since the first filter press plate 22 and the second filter press plate 23 completely overlap when the inclined groove 11 is squeezed in the first process, the entire inner cavity of the inclined groove 11 is filled with sludge, thereby solving the problem of how to fill the mixture of sludge and water into the inclined groove 11.

[0033] In one embodiment, for the drainage holes, the filter press plate 10 is provided with a plurality of drainage holes 14 near the corners.

[0034] When in use, since the inclined grooves 11 are provided on both sides of the filter press plate 10, when the inclined grooves 11 are filled with sludge and squeezed, the moisture in the sludge flows out from a plurality of drainage holes 14 opened near the corners of the filter press plate 10, thereby fully draining the moisture in the inclined grooves 11, solving the problem of where to drain the moisture gathered in the inclined grooves 11 after squeezing the mixture of sludge and water.

[0035] In one embodiment, for the above-mentioned drain pipe 15, the drain pipe 15 is fixedly installed at the lower ends of both sides of the filter press plate 10, and the upper end of the drain pipe 15 is fixedly installed with a support frame 16, and the support frame 16 is clamped on the support plate 6 by gravity.

[0036] When in use, when the moisture in the inclined groove 11 is discharged into the plurality of drainage holes 14 opened near the corners of the filter press plate 10, the moisture in the drainage holes 14 above the filter press plate 10 flows into the drainage holes below the filter press plate 10 through the channels between the drainage holes, and the moisture gathered below the drainage holes 14 is discharged through the drainage pipes 15 fixedly installed at the lower ends of both sides of the filter press plate 10, thereby solving the problem of where to discharge the moisture gathered in the drainage holes 14.

[0037] In one embodiment, for the above-mentioned feed pipe, the filter press plate 10 includes a feed filter press plate 17 clamped on the support plate 6 by gravity, and a feed pipe 18 is fixedly mounted on the upper surface of the feed filter press plate 17.

[0038] When in use, when there is external feeding equipment feeding, a feeding pipe 18 is fixedly installed on the upper surface of the feeding filter press plate 17 to feed the mixture of sludge and water into the feed inlet hole.

[0039] In one embodiment, for the above-mentioned filter screen, support blocks 19 are fixedly installed on both sides of the inner wall of the return water tank 1, and the filter screen 31 is clamped on the upper surface of the support block 19 by gravity.

[0040] When in use, when the water gathered in the drainage hole 14 flows out of the drain pipe 15, the discharged filtered water passes through the upper surface of the support block 19 and is connected to the filter screen 31 by gravity. This solves the problem that when the filtered water is directly discharged into the pool without being filtered again, the amount of sludge precipitation in the pool will be further increased, making it difficult to clean.

[0041] In one embodiment, for the above drainage, a drainage hole 20 is opened on one side of the pipe return pool 1.
