Description

Single-tank agricultural irrigation water filtering device with back flushing function Technical Field The utility model relates to agricultural irrigation equipment, in particular to a single-tank agricultural irrigation water filtering device with backwashing function. Background The agricultural irrigation water is generally taken from natural water flows such as stream water and mountain spring water, so that the irrigation water is mixed with a lot of sediment, small broken stone and other impurities, the irrigation water is further required to be added with fertilizer, fermentation powder and other substances, more granular impurities generally exist in the fertilizer and the fermentation powder, and the irrigation water is required to be filtered through a filtering device firstly in order to avoid the blockage of the impurities to an irrigation pipeline and a water outlet. The traditional filtering device is generally provided with a filtering tank, a filtering component is arranged in the tank body, irrigation water is fed into the filtering tank and is filtered by the filtering component and then is sent out, after a certain amount of impurities are stacked in the filtering tank, the filtering component is required to be detached and cleaned, the operation is very troublesome, time and labor are wasted, some filtering devices capable of being automatically cleaned are also arranged on the market, but the whole structure is very complicated, in the actual use process, the cleaning effect of the internal impurities is poor, and the user experience is poor. Disclosure of utility model In view of the shortcomings of the background art, the technical problem to be solved by the utility model is to provide a single-tank agricultural irrigation water filtering device with backwash for solving the problems. For this purpose, the utility model is realized by adopting the following scheme: The utility model provides a take single jar formula agricultural irrigation water filter equipment of back flush, includes the jar body, the internal filter component that is provided with of jar, the one end and the inlet tube switch-on of the jar body, the other end and outlet pipe switch-on, its characterized in that: the filter component comprises a filter screen, the filter screen encloses out and takes single open structure, just single opening and outlet pipe switch-on for impurity after filtering is located between filter screen and the internal wall of jar, the lateral wall of jar body is provided with the exhaust pipe rather than the interior space intercommunication, corresponds the exhaust pipe and is provided with first on-off control valve, switch-on through the reverse flow pipe between inlet tube and the outlet pipe, corresponds the reverse flow pipe and is provided with the second on-off control valve, corresponds the inlet tube and is provided with the third on-off control valve, and between the connecting end of reverse flow pipe and inlet tube and the jar body, corresponds the outlet pipe and be provided with fourth on-off control valve, and the rear side of fourth on-off control valve and outlet pipe connecting end.
