Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a filter sand recovery and treatment device. Background Art

[0002] Filter sand is a type of sand used to filter suspended matter from flowing liquids.

One side of the collection box 04 is connected to a post-filtering mechanism connected to the intermediate filtering mechanism. The collection box 04 collects and performs different filtration on the limited multiple filtering mechanisms of other devices, thereby ensuring the interception and collection of the filter sand. The water filter plate 23 is fixedly connected in the collection box 04. The bottom of the water filter plate 23 is fixedly connected to the water filter box 24. The bottom of the water filter box 24 is provided with a drip pipe 26 connected to the intermediate filtering mechanism. The water filter plate 23 intercepts and the water filter box 24 performs re-filtration to ensure that the water passes through while the filter sand is intercepted and then the filter sand is dried.

[0026] The primary filtering mechanism includes: a filter plate 11, which is provided with two. The filter plates 11 are fixedly connected to the filter box 02. The bottom of the filter plate 11 is connected to a collecting sleeve 12. One side of the collecting sleeve 12 is fixedly connected to a return pipe 06 connected to the concentrating plate 07. The filter plate 11 performs early filtering of large pieces of filter sand, and then, through the action of gravity, it is intercepted into the collecting sleeve 12 for temporary storage, and then output through the output of the return pipe 06. The two filter plates 11 intercept filter sand of different particle sizes. The guide plate 13 is connected to the filter box 02 at one end and extends to the intermediate filtering mechanism at the other end. The water filtered by the filter plate 11, then flows through the guide plate 13 under the action of pressure and enters the intermediate filtering mechanism for subsequent filtration.

[0027] The intermediate filtering mechanism includes: a water storage tank 14, which is arranged at the bottom of the collection box 04, and the water storage tank 14 is fixedly connected to a filter strip 27 located in the collection box 04, one end of the guide plate 13 extends into the partition box 17, and a guide plate 28 is fixedly connected to one side of the partition box 17. One end of the guide plate 13 is connected to the guide plate 28, and there are multiple filter strips 27. The filter strips 27 are fixedly connected to the guide plate 28, and a return pipe 4 25 is connected at the angle between the filter strips 27 and the guide plate 28. The other end of the return pipe 4 25 is connected to the concentrating plate 1 07. The water storage tank 14 stores water and at the same time slows the flow through the filter strip 27, and at the same time intercepts the sediment in the water, stores it between the filter strip 27 and the guide plate 28, and then discharges it through the return pipe 4 25.

[0028] The post-filtration mechanism includes: a storage box 21, which is fixedly connected to the collection box 04, a water guide box 05 fixedly connected to the storage box 21, a plurality of filter strips 19 fixedly connected to the water guide box 05, a sand discharge pipe 22 fixedly connected to the water guide box 05 is provided on one side of the filter strip 19, one end of the sand discharge pipe 22 extends into the storage box 21, and a return pipe 08 connected to the concentrating plate 2 31 is connected to one side of the storage box 21. After the water flows through the water guide box 05, it is blocked by the filter strip 19 and is discharged. The water flow is buffered and slowed down. At the same time, the filter strip 19 intercepts and filters the water, and at the same time ensures the flow of the water. The intercepted water enters the return pipe 2 08 through the sand discharge pipe 22 for short-term storage. The water pump 15 is arranged in the water storage tank 14. The output end of the water pump 15 is connected to the water supply pipe 16. The top of the water supply pipe 16 is connected to the diverter strip 18 located in the water guide box 05. The water is pumped by the water pump 15 and then overflows through the water supply pipe 16 and the diverter strip 18 to guide the water flow.

[0029] The pumping mechanism includes: a circulation pump 29, which is located in the extraction box 01, and the input end of the circulation pump 29 is connected to the concentrating pipe 30 connected to the concentrating plate 1 07 and the concentrating plate 2 31. The circulation pump 29 is an existing mechanism, which pumps water, and then extracts the water in the concentrating plate 1 07 and the concentrating plate 2 31 through the conduction of the concentrating pipe 30 to form a circulation, and a diverter box 32, which is arranged in the extraction box 01. The diverter box 32 is connected to the output end of the circulation pump 29, and one side of the diverter box 32 is connected to the return pipe 10 connected to the collection box 04. After the circulation pump 29 pumps, the water-containing filter sand passes through the diverter box 32 and the return pipe 10 into the collection box 04 for collection.

[0030] The bottom of the water guide box 05 is connected to a return pipe three 09 connected to the concentrating plate two 31, and one side of the water guide box 05 is connected to a water outlet pipe 20.

[0031] Filter strip 2 27 and filter strip 1 19 are both provided with a plurality of leakage holes. The sand discharge pipe 22 and the dripping pipe 26 are connected with electromagnetic valves. The leakage holes leak water to ensure the passage of water. The electromagnetic valve controls the on-off and intermittent collection.

[0032] The top of the filter box 02 is connected to the water inlet pipe 03, which is set at an angle. An observation door is set on one side of the concentrating plate 07. The water inlet pipe 03 is used to let water in. The observation door is convenient for observing the interior and supervising the interior.

[0033] A cleaning pipe is connected to one side of the water tank 14, and filter cotton is laid on the water filter plate 23. The cleaning pipe facilitates cleaning of the interior, and the filter cotton ensures overall filtration.

[0034] The bottom of the diverter strip 18 is connected to a plurality of dripping pipes, and one side of the partition box 17 is connected to a backwashing pipe. The dripping pipe drips water to slow down the flow rate and potential energy of the water flow. The backwashing pipe is convenient for connecting to external pipes to achieve subsequent cleaning.

[0035] The filter plate 11 is provided with a plurality of leakage holes, and a cleaning pipe is connected to one side of the filter box 02. The leakage holes ensure the flow of water, and the cleaning pipe facilitates the cleaning of the interior.

[0036] The implementation principle of the embodiment of this application is:

[0037] The filtered sand is then collected by the sand discharge pipe 22 and discharged through the return pipe 25. The filtered water then flows into the water storage tank 14 through the water pump 15. The water in the water storage tank 14 passes through the upper water pipe 16 and the diverter strip 18 and drips into the water guide box 05. The water then passes through the interception and filtration of the filter strip 19, so that the filter sand is retained. The water then passes through the sand discharge pipe 22 and enters the return pipe 20 for collection. Finally, the water flows out through the outlet pipe 20 to complete the work.

[0038] When passing through the interception, the circulation pump 29 performs intermittent extraction, and then generates negative pressure through the centralizing pipe 30 and the centralizing plate 2 31, and then extracts through the filter sand in the return pipe 1 06, the return pipe 4 25 and the return pipe 2 08, and then the mixed water enters the return pipe 10, and further enters the collection box 04 for storage. Under the action of gravity, the water is filtered through the filter water plate 23 and the filter water box 24, and then drips into the water storage tank 14 through the drip pipe 26 for reflux, reducing the water content of the filter sand. After the filter sand is collected to a certain extent, it is calcined or otherwise treated to remove the organic matter inside, which is convenient for subsequent reuse.

[0039] After a period of treatment, backwashing can be carried out through each pipeline to ensure subsequent reuse.
