Abstract

The invention discloses a backwash filter, which comprises a filter body and a water pump. The filter body comprises a bracket, a shell, an inlet pipe, an outlet pipe and blow-off pipes. A filter screen is fixed in the shell. The inlet pipe is connected to a first port of a three-way filter. A second port of the three-way filter is connected to a water outlet of the water pump. The three-way filter is connected to a second port of a blow-off tee. The tail end of the blow-off pipe is connected to a first port of the blow-off tee. The bottom of the shell is provided with a pressure sensor. A partition plate is fixed inside the shell. The inlet pipe is respectively connected to a first chamber and a second chamber through a tee, and two water outlets of the tee are respectively provided with a first solenoid valve. The top of the first chamber and the top of the second chamber are provided with the outlet pipes, and the bottom of the first chamber and the bottom of the second chamber are provided with the blow-off pipes. The two blow-off pipes are respectively provided with a second solenoid valve. A second port of the blow-off tee is provided with a third solenoid valve. A control panel is arranged outside the shell. The backwash filter of the invention has good filtration effect, backwash is good, and there is no dead angle for cleaning.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a backwash filter. Background technique [0002] With the development of science and technology, my country is moving from traditional agriculture to modern agriculture, and the sources of agricultural water have become more diversified. Due to the diversification of water sources in arid areas, there are a lot of impurities such as sediment in the water sources. Surface river water is mostly used for agricultural water in the arid areas of Northwest China. Since various impurities will interfere with the use of the drip irrigation system during the flow of the river water, in order to prevent the drip irrigation system from being blocked by sediment and improve the service life of the drip irrigation system, the drip irrigation system To work properly, there must be a matching filter. Because the filter is an essential water treatment equipment for the drip irrigation system, ...
