Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically a wastewater treatment filter that is easy to clean. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] Filtration, as a crucial part of the wastewater treatment process, bears the heavy responsibility of removing suspended solids, impurities, and some microorganisms from wastewater, thus purifying the water quality. Mesh filters are currently a commonly used component in wastewater filtration. However, in actual operation, mesh filters quickly trap a large amount of impurities, causing surface clogging and significantly impacting filtration efficiency. Cleaning is necessary, but current mesh filters require manual disassembly and cleaning, which is extremely cumbersome, reducing their effectiveness in filtering wastewater. Furthermore, the disassembly process can easily damage the filter screen, increasing maintenance costs. Therefore, we provide wastewater treatment filters that are easy to clean.

[0024] Other embodiments of this utility model: A threaded connecting seat 3 is fixedly connected to the outer surface of the housing 1. The inner ring of the threaded connecting seat 3 is threadedly connected to the outer surface of the bottom end of the sealing cover 4. A sealing gasket 15 is fixedly connected to the inner bottom wall of the threaded connecting seat 3. A drain pipe 17 is fixedly connected to the upper surface of the sealing cover 4. A drain flange 18 is fixedly connected to the top end of the drain pipe 17. A sewage pipe 21 is fixedly connected to the right side of the housing 1. A connecting flange 22 is fixedly connected to the ends of the water inlet pipe 2 and the sewage pipe 21 that are far apart from each other. A sealing bearing 26 is fixedly embedded in the bottom surface of the housing 1. The inner ring of the sealing bearing 26 is fixedly connected to the outer surface of the drive shaft 10. The connection, via the threaded connection seat 3, facilitates the installation and removal of the sealing cover 4, enabling maintenance and repair of the interior of the housing 1. The sealing gasket 15 enhances the sealing performance between the sealing cover 4 and the housing 1, preventing leakage of sewage or cleaning water and ensuring the normal operation of the filter. The drain pipe 17 and drain flange 18 allow the filtered clean water to be discharged. The drain flange 18 is used to connect to subsequent pipes, facilitating the delivery of clean water to a designated location. The sewage pipe 21 can be used to discharge sewage containing impurities during the cleaning process. Through the two connecting flanges 22, it is easy to connect to external pipes, enabling the inflow of sewage and the discharge of impurities.

[0025] Other embodiments of this utility model: A through hole 12 is provided on the bottom surface of the filter cylinder 7, and the drive shaft 10 is located inside the through hole 12. The side of each inner cleaning brush 14 that is far apart from each other is in contact with the inner ring of the filter cylinder 7, and the side of each outer cleaning brush 13 that is close to each other is in contact with the outer surface of the filter cylinder 7. Two mounting plates 23 are fixedly connected to the outer surface of the housing 1, and two mounting holes 24 are provided on the bottom surface of each of the two mounting plates 23. A water inlet solenoid valve 25 is fixedly connected to the outer surface of the water inlet pipe 2, and a sewage discharge solenoid valve 27 is fixedly connected to the outer surface of the sewage discharge pipe 21. A limit ring 16 is fixedly connected to the inner ring of the housing 1 for limiting... The upper surface of ring 16 contacts the outer surface of filter cylinder 7.

The inlet solenoid valve 25 controls the inflow of wastewater to be treated and can be opened or closed as needed to achieve precise control of the filtration process. The drain solenoid valve 27 controls the discharge of wastewater containing impurities. It is opened during the cleaning process and closed after cleaning to ensure that wastewater can be discharged in time and prevent backflow. The limit ring 16 can limit the filter cylinder 7 to ensure the stability of filter cylinder 7.

[0026] The working principle of this utility model is as follows: First, the sewage to be treated enters the housing 1 through the inlet pipe 2. The sewage entering the housing 1 comes into contact with the filter screen 7. Due to the interception effect of the filter screen 7, suspended solids and impurities in the sewage are trapped on the filter screen 7, while the filtered clean water passes through the filter screen 7 and flows inside. When it is necessary to clean the filter screen 7, the inlet solenoid valve 25 is closed to stop the sewage from flowing in, and then the water injection solenoid valve 19 is opened. The cleaning water enters the annular pipe 5 through the water injection connector 20, and then flows through multiple cleaning spray nozzles on the bottom surface of the annular pipe 5. The head 6 sprays water into the housing 1 to rinse the surface of the filter cylinder 7. At the same time, the output end of the drive motor 9 drives the drive shaft 10 to rotate. The drive shaft 10 drives multiple outer cleaning brushes 13 and multiple inner cleaning brushes 14 to rotate. The outer cleaning brushes 13 brush the outer surface of the filter cylinder 7, and the inner cleaning brushes 14 brush the inner ring of the filter cylinder 7. This helps to remove impurities attached to the filter surface. Then, the drain solenoid valve 27 is opened, allowing the wastewater containing impurities to be discharged from the housing 1 through the drain pipe 21, thereby completing the automatic cleaning of the filter cylinder 7.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
