Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a wastewater treatment filtration device. Background Technology

[0002] Wastewater treatment utilizes physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, thus fully utilizing water resources. Wastewater treatment typically employs filtration devices to remove particulate matter and impurities from the wastewater. These impurities can clog the filter pores, necessitating the removal and cleaning of the filter. However, this process requires operators to stop the machine, wasting considerable time and impacting filtration efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a wastewater treatment filtration device with a simple structure and improved filtration efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment filtration device, comprising a frame, a wastewater tank mounted on the frame, a wastewater inlet at the upper end of the wastewater tank, a wastewater outlet at the lower end of the wastewater tank, a filtration pool on one side of the wastewater tank, a first filter barrel and a second filter barrel for filtering wastewater mounted in the filtration pool, an outlet pipe connected to the wastewater outlet, and a first branch pipe and a second branch pipe connected to the end of the outlet pipe, the outlet end of the first branch pipe being positioned above the opening of the first filter barrel, and the outlet end of the second branch pipe being positioned above the opening of the second filter barrel, and a switching valve mounted on the outlet pipe for opening the outlet pipe and the first branch pipe, and closing the outlet pipe and the second branch pipe, or opening the outlet pipe and the second branch pipe and closing the outlet pipe and the first branch pipe.

[0005] By adopting the above technical solution, the wastewater tank is used to hold wastewater, so that the wastewater is not directly placed into the filter pool for filtration. The wastewater is first placed into the wastewater tank through the wastewater inlet, and then discharged along the direction of the filter pool through the wastewater outlet. The first filter barrel and the second filter barrel are set to filter impurities in the wastewater. The filtered water is placed into the filter pool. The first water distribution pipe and the second water distribution pipe are set to cooperate with the first filter barrel and the second filter barrel respectively for water filtration. When the first filter barrel needs to be cleaned, the outlet pipe and the first water distribution pipe can be closed by switching valve, while the outlet pipe and the second water distribution pipe are opened. This changes the filtration of wastewater from the first filter barrel to the second filter barrel. Through the alternating filtration of the first filter barrel and the second filter barrel, there is no need to stop the machine to clean the filter barrel. The cleaning process will not affect the drainage in the pipeline, ensuring uninterrupted wastewater drainage and improving wastewater filtration efficiency.

[0006] The present invention further comprises: a partition plate is provided inside the filter pool, the partition plate dividing the interior of the filter pool into a first pool body and a second pool body, the first filter barrel and the second filter barrel being placed into the first pool body and the second pool body respectively; a first mounting plate is provided on both the left and right sides of the partition plate; a second mounting plate is provided on both sides of the filter pool facing the inner sidewall of the first mounting plate; a first annular ear is provided on the outer edge of the opening of the first filter barrel and the second filter barrel; the left and right sides of the first annular ear are respectively mounted on the first mounting plate and the second mounting plate.

[0007] By adopting the above technical solution, the partition plate not only divides the filtration pool into a first pool and a second pool, but also serves to install a first mounting plate. This first mounting plate cooperates with a second mounting plate on the inner wall of the filtration pool to install a first filter barrel and a second filter barrel. The first filter barrel and the second filter barrel are respectively mounted in the first pool and the second pool through a first annular ear, so that there is a certain height difference between their bottoms and the bottoms of the first pool and the second pool, thereby further improving the filtration effect of the first filter barrel and the second filter barrel.

[0008] The present invention further includes a drainage pipe at the bottom of the filter pool, and the bottoms of the first pool and the second pool are connected.

[0009] By adopting the above technical solution, the water filtered by the first filter barrel and the second filter barrel flows into the first pool and the second pool respectively. The bottom of the first pool and the second pool are connected, and the filtered water can be discharged through the same drainage pipe, which simplifies the structure.

[0010] The present invention further includes: both the first pool and the second pool include a filtration space for filtering wastewater and a replacement space for removing the first filter bucket and the second filter bucket. The filtration spaces correspond to the positions of the first water distribution pipe and the second water distribution pipe, respectively. A protective cover is provided on the filtration space to cover the filtration space. The protective cover has an opening on the side facing the replacement space for the first filter bucket and the second filter bucket to be moved out of the filtration space.

[0011] By adopting the above technical solution, the protective cover plate on the filtration space is used to prevent wastewater from splashing up along the opening of the filtration tank when it flows out of the first water distribution pipe to the first filter tank for filtration or from the second water distribution pipe to the second filter tank for filtration, thus providing protection. The replacement space allows the first or second filter tank to be moved from the filtration space to the replacement space when it needs cleaning. The operator can then remove the first or second filter tank from the replacement space for cleaning, and after cleaning, place it back into the replacement space and push it back into the filtration space for filtration. The opening provides space for the movement of the first and second filter tanks, facilitating their movement.

[0012] The present invention further comprises: a sliding assembly provided on both the first mounting plate and the second mounting plate; the sliding assembly includes a slide rail and a slider adapted to the slide rail; the slide rail is provided on the first mounting plate and the second mounting plate; the slider is provided on the slide rail; the slider is provided with a mounting post; the first annular ear is provided with a mounting hole corresponding to the position of the mounting post; the first annular ear is inserted into the mounting post through the mounting hole.

[0013] By adopting the above technical solution, when the first filter cartridge or the second filter cartridge needs to be moved from the filtration space to the replacement space, the operator can pull the first filter cartridge or the second filter cartridge through the sliding component. This allows the first filter cartridge or the second filter cartridge to move back and forth along the slide rail through the mounting hole of the first annular ear and the mounting post on the slider. This makes the movement of the first filter cartridge and the second filter cartridge smoother and more convenient, improving structural stability. The first annular ear is connected to the mounting post through the mounting hole, which facilitates the disassembly and assembly of the first filter cartridge and the second filter cartridge, making cleaning and replacement more convenient and faster.

[0014] The present invention further comprises: both the first filter barrel and the second filter barrel include an outer barrel body and an inner barrel body, wherein the inner barrel body is coaxially arranged with the outer barrel body and inserted into the outer barrel body, and the diameter of the filter holes on the inner barrel body is larger than the diameter of the filter holes on the outer barrel body.

[0015] By adopting the above technical solution, the outer and inner barrels serve a dual filtration function. Furthermore, the filter holes on the inner barrel are larger than those on the outer barrel, allowing wastewater to undergo preliminary filtration through the inner barrel before being further filtered by the outer barrel, thus enhancing the filtration effect and making the filtration more precise.

[0016] The present invention further includes: a second annular ear is provided on the outer edge of the opening of the inner barrel, the second annular ear is mounted on the first annular ear, and there is a gap between the outer bottom wall of the inner barrel and the inner bottom wall of the outer barrel.

[0017] By adopting the above technical solution, the second annular ear allows the inner barrel to be mounted on the outer barrel, facilitating the assembly and disassembly of the outer and inner barrels. The gap between the outer and inner barrels improves the filtration effect of the inner barrel when filtering wastewater, further enhancing the reliability of the structure.

[0018] The present invention is further provided with a handle hinged to both the first and second annular ear portions.

[0019] By adopting the above technical solution, the handle on the first annular ear makes it convenient for operators to move the first or second filter canister from the filtration space to the replacement space by pulling the handle. It also facilitates the disassembly and assembly of the first or second filter canister from the replacement space, making the operation convenient. The handle on the second annular ear facilitates the disassembly and assembly of the inner canister on the outer canister, further improving the reliability of the structure.
