Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency filter cartridge wastewater treatment device. Background Technology

[0002] Wastewater treatment equipment is a specialized facility used to purify and treat domestic sewage, industrial wastewater, and other pollutants. It removes pollutants through physical, chemical, or biological technologies to ensure the water meets discharge or reuse standards. Its core processes include bar filtration, sedimentation tank settling, biological reaction (such as activated sludge process or MBR membrane bioreactor), and disinfection (ultraviolet or chlorine treatment). It can adapt to different scales of needs (such as municipal wastewater treatment plants, industrial parks, or decentralized rural treatment). Modern equipment emphasizes energy efficiency and high performance, enabling the resource utilization of wastewater, which is crucial for protecting aquatic ecosystems and sustainable development.

[0003] For example, authorization announcement number CN219964144U relates to a filter element structure for a sewage treatment device, including a sewage treatment device body, a cover plate movably hinged to the outside of the sewage treatment device body, and a water inlet hopper fixedly connected to the upper surface of the cover plate. A filter element is disposed inside the sewage treatment device body, and mounting structures are provided on the sewage treatment device body and the filter element. A positioning structure extending into the outside of the sewage treatment device body is provided. The mounting structure includes a fixing plate fixedly mounted on the side wall of the filter element, a mounting seat fixedly mounted on the inner wall of the sewage treatment device body, and a mounting block fixedly mounted on the fixing plate near the mounting seat. This sewage treatment device filter element structure allows for quick disassembly and assembly by opening the cover plate and using an electric push rod to disengage the insert rod from the mounting block. Then, the filter element can be moved out of the sewage treatment device body using a lifting lug, achieving a quick disassembly and assembly effect, and demonstrating strong practicality and ease of disassembly and assembly.

[0004] In the aforementioned technology, the filter element of the sewage treatment equipment is arranged in a plate shape. After the impurities in the sewage are filtered by the plate filter element, they accumulate on the upper part of the filter element. Long-term use affects the filtration efficiency of the filter element and increases the frequency of cleaning and replacement of the filter element. Therefore, the market urgently needs to develop a high-efficiency filter element sewage treatment equipment to help people solve the existing problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a high-efficiency filter cartridge sewage treatment device, including a sewage treatment tank 1. An inlet pipe 101 is fixedly connected to one side of the middle of the upper end face of the sewage treatment tank 1. A tubular filter cartridge 2 is arranged in the middle of the inside of the sewage treatment tank 1. A connecting pipe 201 is fixedly connected to the lower end of the tubular filter cartridge 2. An external threaded pipe 104 is fixedly connected to the middle of the lower end face of the sewage treatment tank 1. The lower end of the connecting pipe 201 extends through the middle of the external threaded pipe 104 and out of the lower end of the sewage treatment tank 1, and is fixedly connected to a tightening ring 202. The lower end of the connecting pipe 201 extends through the middle of the tightening ring 202 and is connected to a drain pipe 203. Sewage enters the inside of the sewage treatment tank 1 through the inlet pipe 101, is filtered by the tubular filter cartridge 2, and is discharged through the connecting pipe 201 and the drain pipe 203.

[0024] Please see Figure 2 and Figure 4The lower end of the connecting pipe 201 is connected to the drain pipe 203 via a flange. An internal thread cap 204 is fitted on the outer side of the tightening ring 202. The internal thread cap 204 is fitted onto the outside of the external thread pipe 104 and is threadedly connected and fixed to the external thread pipe 104. When the internal thread cap 204 is connected to the external thread pipe 104, it pushes the upper end of the tightening ring 202 to press against the lower end of the external thread pipe 104, thereby fixing the connecting pipe 201 and its tubular filter element 2. By separating the internal thread cap 204 from the external thread pipe 104, the connecting pipe 201 and its tubular filter element 2 can be pulled out from inside the external thread pipe 104, thereby replacing the tubular filter element 2. At the same time, the impurities filtered by the sewage treatment tank 1 can be discharged and cleaned from the outside of the external thread pipe 104.

[0025] Please see Figure 2 and Figure 3 Four agitator plates 3 are arranged in a ring array on the outer side of the tubular filter element 2. Each of the four agitator plates 3 has a brush portion 301 on its inner side. A support ring 302 is connected to the lower end of each of the four agitator plates 3. The upper ends of the four agitator plates 3 extend beyond the upper end of the tubular filter element 2 and are fixedly connected to a rotating plate 303. A fixing ring 102 is fitted around the lower end of the support ring 302 and outside the connecting pipe 201. The lower end of the fixing ring 102 is fixedly connected to the lower inner surface of the sewage treatment tank 1 by multiple support rods 103. The lower end of the 02 is connected to the fixed ring 102 by a bearing, and the upper end of the rotating plate 303 is connected to the upper inner surface of the sewage treatment tank 1 by a bearing. The rotating plate 303 drives the four stirring plates 3 to rotate synchronously, thereby causing the sewage inside the sewage treatment tank 1 to rotate. This causes impurities in the sewage to accumulate on the inner wall of the sewage treatment tank 1 under the action of centrifugal force. At the same time, the brush part 301 on the inner side of the four stirring plates 3 brushes the outer wall of the tubular filter element 2 when it rotates, preventing the tubular filter element 2 from becoming clogged.

[0026] Please see Figure 2 A limiting tube 105 is fixedly connected to the middle of the upper end face of the sewage treatment tank 1. A driving device 4 is fixedly connected to the upper end face of the sewage treatment tank 1 and the upper end of the limiting tube 105. A driving motor 401 is fixedly installed inside the driving device 4. A rotating shaft 304 is fixedly connected to the middle of the upper end of the rotating plate 303. The upper end of the rotating shaft 304 passes through the middle of the limiting tube 105 and extends into the interior of the driving device 4 and is fixedly connected to the output shaft of the driving motor 401. The driving motor 401 drives the rotating shaft 304 and the lower rotating plate 303 to rotate.

[0027] Working Principle: During operation, wastewater enters the wastewater treatment tank 1 through the inlet pipe 101. The drive motor 401 is activated, rotating the rotating shaft 304, which in turn drives the rotating plate 303 and four agitator plates 3 to rotate synchronously. The rotation of the agitator plates 3 causes centrifugal motion in the wastewater, pushing suspended impurities towards the inner wall of the tank, reducing the adhesion of impurities to the surface of the tubular filter element 2. Simultaneously, the brush portion 301 on the inner side of the agitator plate 3 continuously brushes the outer wall of the tubular filter element 2, preventing clogging of the filter pores. The filtered water, under pressure, passes through the tubular filter element 2 into the connecting pipe 201 and is finally discharged through the drain pipe 203. For maintenance, the tubular filter element 2 can be pulled out entirely by unscrewing the internal thread cap 204, facilitating cleaning of sediment at the bottom of the tank or replacement of the filter element. This design, combining dynamic filtration with self-cleaning, significantly improves filtration efficiency and extends the service life of the filter element.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
