Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation equipment, in particular to a sedimentation device for desludging silica sand. Background Art

[0002] In the process of processing silicon raw stone, after the silicon raw stone is ground into small sand particles, the sand particles need to be washed. Since the silicon raw stone will be contaminated with a lot of mud during the mining process, it needs to be washed with water. The desludging of silica sand is usually completed through a desludging device.

[0003] The application number in the existing public technology is: CN202222488552.4 A silica sand grading sedimentation tank, including a box body, a partition is provided in the middle of the box body, and the partition divides the inner cavity of the box body into a natural sedimentation tank and a flocculation sedimentation tank, and the bottom of the box body corresponding to the natural sedimentation tank and the flocculation sedimentation tank is provided with a mud storage bucket; the upper end of the inner wall of the natural sedimentation tank and the flocculation sedimentation tank is provided with a baffle. The silica sand grading sedimentation tank adopts the natural sedimentation and flocculation sedimentation grading sedimentation mode, and can perform solid-liquid separation twice under the action of gravity sedimentation, and can discharge the silica sand and flocculants in the sewage in turn, which is convenient for the recovery of silica sand. At the same time, the water inside the natural sedimentation tank and the flocculation sedimentation tank flows from bottom to top and is discharged after filtration, so as to achieve the effect of clear water overflow, which can reduce impurities in the overflow clear water, has a good sewage treatment effect, and is convenient for the reuse of treated water.

[0004] However, the above patent still has certain disadvantages when in use: it uses a mesh plate to achieve the barrier filtration operation of silica sand and flocculants, but when the liquid flows, some substances will still be transported upward. At this time, this part of the substance will adhere to the surface of the mesh plate or even clog the holes. This will not only cause a reduction in the amount of subsequent sedimentation, but also affect the normal circulation of the liquid, reducing the overall use effect of the device, and when removing the sediment, it is easy to discharge a large amount of untreated liquid at the same time, affecting the overall quality of use.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0039] Working principle: In actual use, the sewage can be introduced through the liquid inlet pipe 2. At this time, the sewage will first enter the natural sedimentation tank 5. At this time, the liquid is poured in from the top and falls to the bottom. Then, with the continuous introduction of sewage, the liquid level will become higher and higher, and finally the liquid will show a trend of flowing from bottom to top. At this time, the upward liquid will pass through the filter holes 14 on the surface of the baffle 4 for filtration, and the larger particles of silica sand in the sewage will naturally settle into the sedimentation bucket 23 on the lower side, while the rest of the sewage will enter the flocculation sedimentation tank 8 through the flow port 7 on the surface of the partition 6. At this time, flocculants can be added thereto to achieve The flocculation treatment of other impurities in the sewage is carried out, and after the addition is completed, the operation of the second motor 15 can drive the driving shaft 16 to rotate, so that the stirring blades 17 drive the sewage and the flocculant to stir and mix, thereby improving the overall flocculation effect, and thus achieving better treatment of the sewage, and the flocculated products will be blocked by the filter holes 14 above, and then settle in the sedimentation bucket 23 below, and when the silica sand and flocculants are blocked, the operation of the first motor 3 can drive the screw rod 24 to rotate back and forth, thereby driving the scraper 25 connected thereto to scrape back and forth at the bottom of the baffle 4, thereby removing the impurities attached to its surface. At the same time, the operation of the first hydraulic rod 11 at the top can drive the connecting plate 12 at the bottom to move downward, and at this time, the dredging thorns 13 on the surface can be inserted into the filter holes 14 to achieve the purpose of removing the blockage, ensuring the subsequent sedimentation volume is sufficient and facilitating the circulation of liquid, which is convenient for subsequent treatment. Then, after settling for a period of time, the sealing plate 28 at the upper position is pushed out by the second hydraulic rod 26 to block the top of the sedimentation bucket 23, and then the sealing plate 28 at the lower position is opened to discharge the silica sand and flocculants settled at the bottom of the sedimentation bucket 23. At this time, the sealing plate 28 at the lower position is opened. The blocking of the sealing plate 28 can prevent the untreated liquid from being discharged together, which can improve the overall discharge quality. In addition, the device adopts natural sedimentation and flocculation sedimentation graded sedimentation methods, which can perform solid-liquid separation twice under the action of gravity sedimentation, and can discharge the silica sand and flocculants in the sewage in turn, which is convenient for the recovery of silica sand. At the same time, the water inside the natural sedimentation tank 5 and the flocculation sedimentation tank 8 flows from bottom to top and is discharged after filtration, thereby achieving the effect of clean water overflow, which can reduce impurities in the overflow clean water, has a good sewage treatment effect, and is convenient for the reuse of treated water. The overall device has the advantages of filter plate dredging, sediment layered discharge, and good use effect.
