Water from the water supply pipe 23 is then pumped by water pump 22 into the water distributor 14 through the outlet pipe 21. This backwashes the holes of the water distributor 14, removing impurities attached to it. The water then flows through the water distributor 14 into the filter cartridge 11, flushing away impurities accumulated on the filter media. When the water reaches halfway up the filter cartridge 11, the second valve 27 is opened. The impurities after backwashing are discharged through the drain pipe 25. A filter screen 26 is installed inside the drain pipe 25. The filter screen 26 can intercept larger filter media, preventing them from being discharged with the sewage and wasting resources. After backwashing, the water pump 22 and the second valve 27 are turned off, and the first valve 24 is opened to restore the filter distributor body 1 to normal filtration operation. This is used to periodically clean the filter media, prevent clogging, extend the service life of the filter media, and reduce maintenance frequency.

[0022] Furthermore, the filter assembly 3 includes a filter cover 31, a flange ring 32, a locking block 33, a bolt 34, and a slot 35. The filter cover 31 is mounted on the outer surface of the filter distributor body 1. A flange ring 32 is provided at one end of the filter cover 31. A locking block 33 is fixedly connected to the outer surface of the flange ring 32. A bolt 34 is mounted on the outer surface of the flange ring 32.

Through the arrangement of the filter cover 31, flange ring 32, locking block 33, bolt 34, and slot 35, the locking block 33 engages with the slot 35. The bolt 34 passes through the flange ring 32. 2. The filter cover 31 extends into the slot 35. Through the engagement of the locking block 33 with the slot 35 and the fixing of the flange ring 32 by the bolt 34, the filter cover 31 can be easily installed and removed. The filter cover 31 can perform preliminary filtration on the water entering the filter distributor body 1, blocking larger impurities in the water from entering the outside of the distributor 14, avoiding clogging of the distributor 14 by impurities, improving the filtration effect and service life of the filter. At the same time, the filter cover 31 is easy and quick to install and remove, making it convenient for users to clean or replace the filter cover 31, ensuring the continuous and efficient operation of the filter.

[0023] Furthermore, the filter water distributor body 1 includes a filter cylinder 11, a water inlet 12, an observation port 13, and a water distributor 14. The water inlet 12 is connected to the upper surface of the filter cylinder 11, the observation port 13 is connected to the upper surface of the filter cylinder 11, and the water distributor 14 is provided on the inner surface of the filter cylinder 11.

[0024] Furthermore, the input end of the water pump 22 is connected to a water supply pipe 23, and the output end of the water pump 22 is connected to a water outlet pipe 21.

The selection of the water pump 22 needs to be determined according to the actual filtration requirements and backwashing requirements to ensure that it can provide sufficient water flow and water pressure to meet the needs of the backwashing work.

[0025] Furthermore, one end of the drain pipe 25 is connected to the filter cylinder 11, and the other end of the drain pipe 25 is connected to the second valve 27. Through the setting of the drain pipe 25, the impurities washed down during the backwashing process and the wastewater after cleaning can be discharged from the filter distributor body 1.

[0026] Furthermore, a first valve 24 is connected to one end of the filter water distributor body 1, and a water outlet pipe 21 is connected to the other end of the filter water distributor body 1. The first valve 24 can control the water flow inside the filter water distributor body 1. When it is necessary to maintain or clean the filter water distributor body 1, the first valve 24 can be closed to cut off the water flow, ensuring the safety and convenience of the maintenance or cleaning process. At the same time, when the filter water distributor body 1 is working normally, the first valve 24 remains open, allowing water to flow smoothly and ensuring the normal filtration function of the filter.

[0027] Furthermore, the outer surface of the locking block 33 matches the inner surface of the slot 35, and the bolt 34 passes through the flange ring 32 and connects to the filter distributor body 1. The locking block 33 can be tightly engaged with the slot 35 to prevent the filter cover 31 from loosening or falling off during use, thus ensuring the stability and reliability of the filter cover 31.

[0028] Working Principle: In actual operation, when the user needs to clean the filter media and water distributor 14 inside the filter cartridge 11, firstly close the first valve 24 and the second valve 27. Then, the water pump 22 sends water from the water supply pipe 23 into the water distributor 14 through the outlet pipe 21 to backwash the holes of the water distributor 14, thereby washing away the impurities attached to the water distributor 14. The water flowing through the water distributor 14 into the filter cartridge 11 can also wash away the impurities accumulated on the filter media. When the water reaches halfway up the filter cartridge 11, the second valve 27 is opened. The impurities after backwashing will be discharged through the drain pipe 25. A filter screen 26 is also installed inside the drain pipe 25. The filter screen 26 can intercept larger filter media to prevent them from being discharged with the sewage, thus avoiding waste of resources. After the backwashing is completed, the water pump 22 and the second valve 27 are closed, and the first valve 24 is opened to allow the water to flow back into the filter cartridge 11. The filter distributor body 1 resumes normal filtration operation, used for periodic cleaning of the filter media to prevent clogging, extend the service life of the filter media, and reduce maintenance frequency. Through the setting of the filter assembly 3, the locking block 33 engages with the locking groove 35, and the bolt 34 passes through the flange ring 32 and extends into the interior of the locking groove 35. Through the engagement of the locking block 33 and the locking groove 35 and the fixing of the flange ring 32 by the bolt 34, it is convenient to install and remove the filter cover 31. The filter cover 31 can perform preliminary filtration on the water entering the filter distributor body 1, blocking larger impurities in the water from entering the outside of the distributor 14, avoiding impurities from clogging the distributor 14, improving the filtration effect and service life of the filter. At the same time, the installation and removal of the filter cover 31 is convenient and quick, making it easy for users to clean or replace the filter cover 31, ensuring the continuous and efficient operation of the filter.
