[0021] Reference Figure 2 The filter tank assembly 1 includes a filter tank body 10. A filter element outer sleeve 11 is fixedly installed at one end inside the filter tank body 10. An inner filter element 12 is fixedly installed inside the filter element outer sleeve 11. An inner filter element sleeve 13 is fixedly installed inside the inner filter element 12. A tank body upper mounting flange ring 14 is fixedly installed at one end of the upper outer side of the filter tank body 10. A tank body lower mounting flange ring 15 is fixedly installed at one end of the lower outer side of the filter tank body 10. Both the upper and lower ends of the filter element outer sleeve 11 and the filter element inner sleeve 13 are longer than the inner filter element 12. The tank body upper mounting flange ring 14 and the tank body lower mounting flange ring 15 are both provided with multiple sets of through hole structures.

[0022] Reference Figure 3The filter tank cover assembly 2 includes a filter tank cover body 20. A sewage inlet pipe 21 is fixedly inserted through the middle of the filter tank cover body 20. An inner sleeve annular cover 22 is fixedly installed at one end of the sewage inlet pipe 21. A sealing gasket 23 is fixedly installed on the upper inner side of the inner sleeve annular cover 22. A backwash inlet pipe 24 is fixedly connected to one end of the filter tank cover body 20. A filter outlet pipe 25 is fixedly connected to the other end of the filter tank cover body 20. One side of the filter tank cover body 20 is fixed... A filter tank cover mounting flange ring 26 is provided, and an inner sleeve annular cover 22 is located below the filter tank cover body 20. The sealing gasket 23 is an annular gasket structure made of vulcanized rubber. Multiple sets of through holes are evenly opened inside the filter tank cover mounting flange ring 26. The sewage inlet pipe 21 is adapted to pass through the inside of the filter element inner sleeve 13. The inner sleeve annular cover 22 is adapted to be installed above the filter element inner sleeve 13. The filter tank cover mounting flange ring 26 is compatible with the specifications of the lower mounting flange ring 15 of the tank body.

[0023] Using the above solution: by inserting the sewage inlet pipe 21 into the inner sleeve 13 of the filter element in the filter tank assembly 1 until the inner sleeve annular cover 22 is fitted on the outer side above the inner sleeve 13 of the filter element, the sealing gasket 23 fits against the upper part of the inner sleeve 13 of the filter element to achieve a sealing effect.

[0024] Reference Figure 4 The filter tank bottom assembly 3 includes an arc-shaped filter tank bottom 30. A backwash outlet 31 is fixedly connected through the middle of the arc-shaped filter tank bottom 30. A tank bottom mounting flange ring 32 is fixedly installed on one side of the arc-shaped filter tank bottom 30. Multiple sets of through holes are evenly opened inside the tank bottom mounting flange ring 32. The tank bottom mounting flange ring 32 is compatible with the specifications of the tank body lower mounting flange ring 15.

[0025] The above scheme is adopted as follows: The sewage pump pipeline is connected to the sewage inlet pipe 21 via an electromagnetic valve; the backwash pump pipeline is connected to the backwash inlet pipe 24 via an electromagnetic valve; the filter outlet pipe 25 is connected to the outlet pipe via an electromagnetic valve; and the backwash outlet pipe 31 is connected to the backwash outlet pipe via an electromagnetic valve. During filtration, the electromagnetic valves at the backwash inlet pipe 24 and backwash outlet pipe 31 are closed, while the electromagnetic valves at the sewage inlet pipe 21 and filter outlet pipe 25 are opened. Sewage is pumped from the sewage inlet pipe 21 into the interior of the arc-shaped filter tank bottom 30. After being pressed into the filter element 12 by water pressure, the filter enters the filter tank cover 21 and is finally discharged through the filter outlet 25. By closing the solenoid valves at the sewage inlet pipe 21 and the filter outlet 25, and opening the solenoid valves at the backwash inlet pipe 24 and the backwash outlet 31, the backwash water is pumped into the filter tank cover 20 through the backwash inlet pipe 24 to backwash the filter element 12. The backwashed sewage is discharged through the backwash outlet 31 below, which can quickly complete the backwash cleaning of the filter element 12 and achieve efficient filtration.

[0026] The working principle of this utility model is as follows: During use, the sewage inlet pipe 21 is inserted into the inner sleeve 13 of the filter element within the filter tank assembly 1 until the annular cover 22 of the inner sleeve is fitted onto the outer side of the inner sleeve 13. At this point, the sealing gasket 23 adheres to the upper part of the inner sleeve 13, providing a sealing effect. Then, the flange ring 14 and the filter tank cover mounting flange ring 26 are installed on the tank body, and the fixing bolts pass through the through-hole structure inside to fix the filter tank assembly 1 and the filter tank cover assembly 2. Finally, the bottom mounting flange ring 32 inside the filter tank bottom assembly 3 is installed... Align the bottom flange ring 15 with the bottom flange ring 32 of the tank body, and insert fixing bolts through the through-hole structure inside the bottom flange ring 15 to fix the filter tank assembly 1 and the bottom flange assembly 3. At this time, connect the sewage pump pipeline to the sewage inlet pipe 21 through a solenoid valve, connect the backwash pump pipeline to the backwash inlet pipe 24 through a solenoid valve, connect the filter outlet pipe 25 through a solenoid valve, and connect the backwash outlet pipe 31 through a solenoid valve. During filtration, the solenoid valves at the backwash inlet 24 and backwash outlet 31 are closed, while the solenoid valves at the wastewater inlet 21 and filter outlet 25 are opened. Wastewater is pumped into the arc-shaped filter tank bottom 30 through the wastewater inlet 21, then forced into the inner filter element 12 by water pressure, filtered, and finally discharged into the filter tank cover 21 through the filter outlet 25. When the inner filter element 12 becomes clogged, the solenoid valves at the wastewater inlet 21 and filter outlet 25 are closed, and the solenoid valves at the backwash inlet 24 and backwash outlet 31 are opened. The electromagnetic pipe valve at the flushing outlet 31 allows backwash water to be pumped into the filter tank cover 20 through the backwash inlet 24 to backwash the filter element 12. The flushed wastewater is then discharged through the lower backwash outlet 31, thus quickly completing the backwashing and cleaning of the filter element 12. Furthermore, with this structure, larger impurities will flow through the wastewater inlet 21 and fall into the lower arc-shaped filter tank bottom 30, further reducing the clogging of the filter element 12. This makes filtration more convenient and efficient.
