Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a clean water extraction device used in wastewater treatment. Background Technology

[0002] Industrial wastewater, domestic sewage, and agricultural non-point source pollution are rich in organic matter, heavy metals, nitrogen and phosphorus nutrients, as well as substances such as drug residues and microplastics. Direct discharge without effective treatment will lead to serious consequences such as eutrophication of water bodies, accumulation of biotoxicity, and groundwater pollution. Therefore, wastewater treatment has become an important research topic in the environmental protection field. Currently, in order to separate treated water into compliant solutions, prevent sludge resuspension and secondary pollution, and ensure the stable operation of subsequent treatment units, the extraction of supernatant after sedimentation is a crucial step in the wastewater treatment process. In short, supernatant extraction is the core step in achieving "sludge-water separation" in wastewater treatment, directly affecting effluent quality, sludge treatment efficiency, and system operational stability. It is a key link for wastewater treatment plants to achieve environmental compliance and efficient resource utilization.

[0003] However, most current methods of extracting clean water involve using pipelines and pumps. During the water extraction process, it is easy to remove suspended impurities from the bottom of the sewage, which affects the water extraction effect and the subsequent recycling of clean water. Utility Model Content

[0004] The purpose of this application is to provide a clean water extraction device for sewage treatment, in order to solve the problem that the traditional clean water collection process easily removes impurities suspended in the lower part of the sewage, thereby affecting the clean water extraction effect and the subsequent recycling of clean water.

[0005] To solve the above-mentioned technical problems, this application provides a clean water extraction device for sewage treatment, comprising:

[0006] A sedimentation tank is connected to a sewage treatment tank via a pipe. A through hole is provided on the side of the sedimentation tank away from the pipe. An extraction pipe communicating with the through hole is provided on the outside of the sedimentation tank. A pump body is provided on the extraction pipe. A support frame is fixed on the upper side of the sedimentation tank and has an installation hole communicating with the through hole. A threaded rod is screwed onto the support frame. A filter plate is rotatably installed at the lower end of the threaded rod. The filter plate is located in the through hole through the installation hole.

[0007] In a preferred embodiment, a clean water extraction device for sewage treatment is provided, wherein the lower end of the threaded rod is rotatably connected to the upper side of the filter plate via a bearing.

[0008] In a preferred embodiment, a clean water extraction device for sewage treatment is provided, wherein an operating handle is fixed to the upper end of the threaded rod.

[0009] The solution requires detailed explanation of a clean water extraction device for wastewater treatment, wherein a filter screen can be detachably installed inside the sedimentation tank, the through hole is located at the lower part of the filter screen, and the pipe is located at the upper part of the filter screen.

[0010] Further explanation is needed regarding the proposed solution: a clean water extraction device for wastewater treatment includes an installation groove on the inner wall of the sedimentation tank, and a rubber strip on the side of the filter screen, with the rubber strip located within the installation groove.

[0011] Further explanation is needed regarding the proposed solution: a clean water extraction device for wastewater treatment includes a lifting rod fixed in the middle of the filter screen.

[0012] It should be further explained in the solution that a clean water extraction device for sewage treatment has a lifting ring fixed at the upper end of the lifting rod.

[0013] Compared with the prior art, the present invention provides a clean water extraction device for sewage treatment, including a sedimentation tank connected to a sewage treatment tank via a pipeline. The supernatant from the treated sewage flows through the pipeline into the sedimentation tank for initial separation. A through hole is provided on the side of the sedimentation tank away from the pipeline. An extraction pipe communicating with the through hole is provided on the outside of the sedimentation tank, and a pump body is installed on the extraction pipe. A support frame is fixed on the upper side of the sedimentation tank and has an installation hole communicating with the through hole. A threaded rod is screwed onto the support frame, and a filter plate is rotatably installed at the lower end of the threaded rod. The filter plate is installed in the through hole through the mounting hole. The clear water entering the sedimentation tank can settle in the sedimentation tank. After a period of time, the pump body is started to extract the supernatant in the sedimentation tank and separate the supernatant again. During the extraction process, the filter plate can filter the impurities in the supernatant, further preventing the bottom suspended impurities from being drawn into the clear water. After a period of use, the filter plate can be moved up and removed from the mounting hole by turning the threaded rod, so that the impurities stuck to the filter plate can be cleaned. The clear water extraction effect is good and it is conducive to the later recycling of clear water. Attached Figure Description

The sedimentation tank 1 is connected to the wastewater treatment tank via a pipe. Specifically, an inlet hole 01 is provided on one side of the sedimentation tank 1, and the inlet hole 01 is connected to the pipe. The wastewater treatment tank is not shown in the figure. After the wastewater in the wastewater treatment tank is treated, the supernatant can flow through the pipe into the sedimentation tank 1 for further sedimentation. A through hole 5 is provided on the side of the sedimentation tank 1 away from the pipe. An extraction pipe 2 connected to the through hole 5 is provided on the outside of the sedimentation tank 1, and a pump body 3 is installed on the extraction pipe 2. A support frame 4 is fixed on the upper side of the sedimentation tank 1, and an installation hole 6 is provided on the sedimentation tank 1.

In use, the filter plate 8 is located inside the through hole 5 through the installation hole 6 to filter the water. Starting pump 3 allows the supernatant from sedimentation tank 1 to be drawn away through extraction pipe 2, separating it from the turbid liquid at the bottom of sedimentation tank 1. During this process, impurities in the clear water can be filtered through filter plate 8, ensuring effective separation. After a period of use, the filter plate 8 can be moved upwards and disengaged from mounting hole 6 by screwing threaded rod 7.
