Problems solved by technology
[0003] Existing pumping equipment is generally equipped with irrigation water filtration system, and the water pipe is connected with the irrigation water filtration system. In order to ensure that the filtrate is clear enough, it is usually necessary to connect the water pipe to a higher level, and in order to move the irrigation water filtration system. The liquid in the water filtration system should be pumped away as much as possible, and the connecting pipe needs to be set lower. The existing method is to connect the water pipe to the middle of the irrigation water filtration system. The position fluctuates greatly, and its precipitation is not thorough enough

Embodiment
[0046] refer to Figure 1 to Figure 6 , the embodiment of the present invention discloses an irrigation water filtration system, including a base 100 , a sealing cylinder 200 , a first filter 300 , a second filter 400 , a float 500 , a hose 900 and a wedge 600 .
[0047]The sealing cylinder 200 is annular, and the sealing cylinder 200 is installed on the bottom of the base 100. The axis of the sealing cylinder 200 is perpendicular to the base 100. The sealing cylinder 200 includes a housing chamber 210 and an outlet 220. The outlet 220 is located in the sealing cylinder On the side wall of the body 200, the outlet 220 communicates with the accommodating chamber 210; the first filter 300 is installed on the end of the sealing cylinder 200 away from the base 100; the second filter 400 is annular, and the second filter 400 is located on the sealing cylinder 200 Inside, the second filter screen 400 is arranged coaxially with the sealing cylinder 200, and divides the accommodating ...

The application discloses an irrigation water filtration system, which belongs to the technical field of irrigation water filtration systems, and includes a base, a sealing cylinder, a first filter, a second filter, a float, a hose and a wedge. The accommodating cavity of the sealing cylinder is divided into a first cavity and a second cavity, the first filter screen communicates with the first cavity, the float includes a water inlet and a water outlet, the float can slide up and down in the second cavity, and the wedge-shaped block is located on the float On the moving path, and the water inlet of the float is set towards the float. When the irrigation water filtration system disclosed in the present invention is pumping the filtrate, as the liquid level in the sealed cylinder decreases, the degree to which the water inlet of the float is blocked by the wedge-shaped block gradually increases, so that the pumping speed of the filtrate increases as the liquid level decreases. The drop of the liquid level gradually slows down, so that the liquid located in the lower part of the sealed cylinder has more time to settle, and when the pumping speed decreases, the fluctuation of the liquid is also small, which can prevent the sediment from refloating.
Description
technical field [0001] The invention relates to the technical field of irrigation water filtering systems, in particular to an irrigation water filtering system. Background technique [0002] Micro-irrigation is a method of uniformly and accurately transporting water and nutrients required for crop growth directly to the soil near the roots of crops at a small flow rate through the pipeline system and the irrigator installed on the final pipeline according to the needs of the crops. Watering method. [0003] The existing pumping equipment is generally equipped with an irrigation water filtration system, and the water pipe is connected with the irrigation water filtration system. In order to ensure that the filtrate is clear enough, it is usually necessary to connect the water pipe to a higher level, and in order to move the irrigation water filtration system. The liquid in the water filtration system should be pumped away as much as possible, and the connecting pipe needs t...
