The screen filter is a precision device that directly intercepts impurities in water, oil and other liquids with a filter screen, removes suspended solids and particles in water and oil, reduces turbidity, purifies water and oil, and reduces system dirt, bacteria, algae, rust and other impurities. To purify liquids such as water and oil, and protect other equipment in the system from normal operation. The mesh filter is suitable for irrigation of various crops such as vegetables, fruit trees, greenhouses, flowers, tea gardens, green belts and fields. Screen filters can save water and energy, improve the quality of plants, enhance product grades, maintain ecological balance, and benefit the country and the people. It is an indispensable irrigation product for the transformation from traditional agriculture to modern agriculture. It can also be used for filtering and purifying industrial oils and chemical liquids. Due to the screen structure of the screen filter, impurities are prone to clogging the screen, thus making the cleaning of the screen the biggest problem. Currently, the cleaning of screen filters is rather difficult.

Technical key points: To overcome the shortcomings of the existing technology, technicians provide a screen filter. By setting nozzles outside the filter screen, the problem of difficult cleaning of the screen filter in the background technology is solved. To solve the above technical problems, the technical solution adopted by this screen filter is as follows: Provide a screen filter, including a housing, a filter element, an inlet pipe and an outlet pipe, with the filter element located inside the housing; The shell is provided with an inlet and an outlet respectively connected to the inlet pipe and the outlet pipe. The filter element is composed of multiple filter screens connected together. The inner side wall of the shell is provided with nozzles facing the filter element. One end of the nozzle inlet pipe passes through the side wall of the shell, and the other end is connected to the water tank. The water tank is connected to the outlet pipe through a three-way pipe. After passing through the three-way pipe, control valves are installed on the nozzle inlet pipe and the outlet pipe. In the above-mentioned screen filter, the housing includes an upper housing and a lower housing. The upper housing and the lower housing are connected by threads. The upper housing is provided with internal threads, and the lower housing is provided with external threads. In the above-mentioned mesh filter, a hollow protrusion is provided at the bottom of the lower shell, which is located in the inner cavity surrounded by the filter screen. The surface of the hollow protrusion is in the form of a hollow mesh, and the deodorizing particles are placed in the hollow protrusion.

The beneficial effects of the above-mentioned screen filter are as follows: A screen filter comprises a housing, a filter element, an inlet pipe and an outlet pipe. The filter element is located inside the housing, and the housing is provided with an inlet and an outlet. The inlet and outlet are respectively connected to the inlet pipe and the outlet pipe. The filter element is composed of multiple filter screens connected together. The inner side wall of the shell is provided with nozzles facing the filter element. One end of the nozzle inlet pipe passes through the side wall of the shell, and the other end is connected to the water tank. The water tank is connected to the outlet pipe through a three-way pipe. After passing through the three-way pipe, control valves are installed on the nozzle inlet pipe and the outlet pipe. By controlling the number of filter screen connections, the length of the filter element formed by the connection of multiple filter screens can be easily controlled. When cleaning, the filter element can be disassembled, which is more convenient for cleaning. There are nozzles on the side wall of the shell, which are equipped with control valves. The filter screen can be cleaned at any time. The operation is simple and the use is convenient.
