Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of greywater treatment equipment, specifically a filtration device for greywater treatment. Background Technology
[0002] In the face of increasingly scarce water resources, greywater, as a recyclable non-traditional water resource, has become a key measure for alleviating water shortages through its treatment and reuse. Greywater is widely used in industrial cooling, urban greening, and road cleaning, effectively reducing reliance on fresh water and improving water resource utilization efficiency. Greywater treatment filtration devices, as the core equipment in greywater production, are responsible for removing suspended solids, impurities, microorganisms, and other pollutants from wastewater, playing a decisive role in ensuring the quality of greywater.
[0003] In recent years, with the rapid development of the environmental protection industry, the market size of greywater treatment has continued to expand. According to relevant data, the market size of greywater reuse in my country reached 58.73 billion yuan in 2024, and is expected to maintain a high-speed growth trend in the coming years. In newly built sewage treatment plants and greywater reuse projects across the country, the application of greywater treatment filtration devices is becoming increasingly widespread, and more and more enterprises and communities are beginning to adopt greywater treatment systems to achieve the purification and reuse of sewage.
[0004] However, existing greywater treatment filtration systems have revealed numerous problems during actual operation, with filter cartridge replacement being particularly challenging. Currently, most greywater treatment equipment uses filter cartridges that, after prolonged use, experience a decline in filtration efficiency due to the trapping of large amounts of impurities, necessitating timely replacement. This process is not only complex but also consumes significant manpower, resources, and time. For example, a greywater treatment plant in a large industrial park requires several days each month for professional technicians to replace the filter cartridges, with each replacement costing tens of thousands of yuan. Furthermore, improper operation during filter cartridge replacement can damage the equipment, affecting the normal operation of the entire greywater treatment system.
[0005] To address the aforementioned problems, a filtration device for greywater treatment is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a filtration device for treating greywater, in order to solve the above problems. The device includes a treatment tank, an inlet at the bottom of the treatment tank, an outlet on one side of the middle of the treatment tank, a filter cartridge fixedly installed inside the treatment tank, a sealing cover fixedly installed on the top of the treatment tank by bolts, a motor fixedly installed on one side of the top of the sealing cover, a stirring rod fixedly installed at the end of the output shaft of the motor, a rotating disk fixedly installed at the bottom of the stirring rod, a connecting frame fixedly installed between the upper wall of the rotating disk and the outer wall of the stirring rod, and a scraper fixedly installed on one side of the connecting frame, the scraper contacting the inner wall of the filter cartridge.
[0007] With the above technical solution, after the treatment tank has been used for a long time, the motor drives the stirring rod to rotate, and the stirring rod drives the scraper to rotate to clean the inner wall of the filter cartridge, preventing dirt from accumulating on the inner wall of the filter cartridge, and eliminating the need for frequent replacement of the filter cartridge.
[0008] In a preferred embodiment, the upper surface of the rotating disk is provided with a plurality of connecting grooves, a rotating rod is rotatably connected inside the connecting grooves, and blades are fixedly installed on the outer wall of the rotating rod.
[0009] With the above technical solution, when sewage enters the treatment tank, the sewage impacts the blades, causing the blades to rotate under force, thereby stirring the bottom of the sewage and creating turbulence. After turbulence is formed, the particulate impurities in the sewage will undergo complex and irregular movements, which greatly increases the probability of collisions between impurities and between impurities and the surface of the filter cartridge, thus improving the filtration effect.
[0010] In a preferred embodiment, an air supply unit is fixedly installed on one side of the outer wall of the treatment tank, and the output end of the air supply unit is fixedly connected to the inside of the treatment tank through a hose.
[0011] In a preferred embodiment, a drain pipe is fixedly installed on one side of the upper surface of the sealing cover.
[0012] Using the above technical solution, the cleaned debris is discharged through the sewage pipe.
[0013] In a preferred embodiment, a solenoid valve is fixedly installed on the outer wall of the sewage pipe.
[0014] In a preferred embodiment, an observation window is provided on one side of the outer wall of the processing tank.
[0015] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are: this utility model proposes a filtration device for greywater treatment.
[0016] 1. After the treatment tank has been used for a long time, the motor drives the stirring rod to rotate, and the stirring rod drives the scraper to rotate to clean the inner wall of the filter cartridge, preventing dirt from accumulating on the inner wall of the filter cartridge, and eliminating the need for frequent replacement of the filter cartridge.
[0017] 2. When wastewater enters the treatment tank, the wastewater impacts the blades, causing the blades to rotate and stir the bottom of the wastewater, creating turbulence. Once turbulence is formed, the particulate impurities in the wastewater will undergo complex and irregular movements, which greatly increases the probability of collisions between impurities and between impurities and the surface of the filter cartridge, thus improving the filtration effect.

A connecting frame 9 is fixedly installed between the upper wall of the rotating disk 8 and the outer wall of the stirring rod 7. A scraper 10 is fixedly installed on one side of the connecting frame 9. The scraper 10 contacts the inner wall of the filter cartridge 5. When the treatment tank 1 is used for a long time, the stirring rod 7 is driven to rotate by the motor 6. The stirring rod 7 drives the scraper 10 to rotate to clean the inner wall of the filter cartridge 5, preventing dirt from accumulating on the inner wall of the filter cartridge 5 and eliminating the need for frequent replacement of the filter cartridge.
[0027] The upper surface of the rotating disk 8 is provided with multiple connecting grooves 14. A rotating rod 15 is rotatably connected inside the connecting groove 14. A blade 16 is fixedly installed on the outer wall of the rotating rod 15. When sewage enters the treatment tank 1, the sewage impacts the blade 16. The blade 16 rotates under the force, thereby stirring the bottom of the sewage and making the sewage turbulent. After the turbulence is formed, the particulate impurities in the sewage will make complex and irregular movements, which greatly increases the probability of collision between impurities and between impurities and the surface of the filter cartridge, thus improving the filtration effect.
[0028] Working principle:
[0029] After the treatment tank 1 has been used for a long time, the motor 6 drives the stirring rod 7 to rotate. The stirring rod 7 drives the scraper 10 to rotate and clean the inner wall of the filter cartridge 5, preventing dirt from accumulating on the inner wall of the filter cartridge 5, thus eliminating the need for frequent replacement of the filter cartridge.
