[0002] A backwash filter is a pressure-type self-cleaning sealed water filter. This filter mainly operates by backwashing based on the pressure difference between the inlet and outlet water to achieve the function of self-cleaning the filter screen. It overcomes many shortcomings of traditional filter products, such as small dirt holding capacity, easy clogging by dirt, the need to disassemble and clean the filter parts, and the inability to monitor the filter status. It has the function of filtering raw water and automatically cleaning and discharging the filter element. The system supplies water continuously during cleaning and discharging, and can monitor the working status of the filter, with a high degree of automation.

[0003] However, existing backwash filters have certain drawbacks in use. First, the connection stability of the filter pipe is poor, and the pipe is easy to fall off from the filter inlet and outlet pipes. Second, the power cord storage at the rear of the electrical control box is poor, and the power cord is easy to get tangled and affect the power supply of the electrical control box.

[0030] Working principle

[0031] This utility model is a backwash filter. In use, water enters the filter body 5 through the inlet pipe. First, it passes through the coarse filter screen to remove larger particles of impurities, and then reaches the fine filter screen. During the filtration process, the fine filter screen gradually accumulates dirt and impurities in the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference is formed between the inside and outside of the fine filter screen. When the filtration time is up or the pressure difference of the filter reaches a preset value, the pressure difference sensor drives motor 6 and motor 2 to operate. Open the water flow guide valve and the drain valve. The backwash filter will then begin backwashing. After backwashing and draining, return the water flow guide valve and drain valve to their initial positions. The filter features a pipe anti-detachment structure 9. During filter installation, the pipe mounting ring 92 can be installed onto the outer wall of the filter's inlet and outlet pipes. Then, the pipe limiting ring 91 can be installed onto the outer wall of the pipe at one end of the inlet and outlet pipes. Adjust the position of the pipe limiting ring 91 using the adjusting bolt 94 as needed. The pipe limiting ring 91 provides auxiliary limiting and fixing of the pipe, improving the connection stability between the pipe and the filter and preventing... If the connecting pipe detaches from the filter inlet and outlet pipes, it will affect the use of the backwash filter. The power cord limiting structure 7 is set up so that before the filter is used, the mounting bracket 71 can be fixed to the upper end of the electrical control box 8. The height of the angle adjusting bracket 75 can be adjusted according to the power supply position by adjusting the second adjusting bolt 72. After the power supply to the electrical control box is turned on, the excessively long power cord is wound around the outer wall of the power cord winding bracket 77, and then the limiting piece 74 limits the wound power cord. This makes it convenient for the installer to store the excessively long power cord at the rear of the electrical control box and avoid the excessively long power cords from getting tangled together and affecting the power supply to the electrical control box.
