Abstract
The invention discloses a water purification filter for a water-saving irrigation system. The water purification filter comprises a shell (5) with a water inlet (1) and a water outlet (8), at least two layer of filter screens of different specifications are arranged between the water inlet (1) and the water outlet (8), drain outlets are formed in one side of the water inlet (1) and between the two layers of filter screens, the drain outlet A (12) is formed in one side of water inlet (1), the drain outlet B (11) is formed between the two layers of filter screens, a back flush water inlet (4) is formed in the position, in one side of the water outlet (8), of the shell (5), and the back flush water inlet (4) is at least formed in the position, opposite to the drain outlet B (11), of the other side of the shell (5). Compared with the prior art, the advantages that the function of achieving double filtering and back flush can be achieved, operation and use can be automatically and conveniently controlled, and back flush can be achieved under the condition of not opening the filter are achieved.
Description
Technical field
The present invention relates to a kind of filter, especially a kind of water-saving irrigation system water purification filter.
Background technology
China's water resource is very short, and water resources ownership per capita is only world average level 1/4th, and agricultural uses water rich and influential family, and therefore, accelerated development agricultural water conservation is imperative.
Some achievements in research of domestic self-cleaning filter can complete the automatic cleaning of filtering contaminants impurity to a certain extent, but its cleaning mechanism or transmission mechanism need external force to drive, be generally motor, or need to set up larger blowdown chamber, add the manufacturing cost and use cost of filter.
Therefore, a kind of manufacture simple, simple structure, realizes composite filtering and backwash, has compression-resistant structure, have and be convenient to automatic structure in housing, operation and easy to use, and can when not opened filter, and the filter realizing backwash is suggested.
Summary of the invention
The object of this invention is to provide a kind of realization in a housing to filter and backwash, there is compression-resistant structure, automaticity height operation and easy to use, have and when not opened filter, the filter of backwashing function can be realized.
The object of the invention is to be realized by following structure: comprise the housing (5) being provided with water inlet (1) and delivery port (8), it is characterized in that: the filter screen being provided with at least two-layer different size between housing (5) interior water inlet (1) and delivery port (8), i.e. large gauge filter screen (6) and small dimension filter screen (7), and large gauge filter screen (6) is arranged at water inlet (1) side, small dimension filter screen (7) is arranged at delivery port (8) side, simultaneously, sewage draining exit is equipped with between water inlet (1) side and two-layer filter screen, namely sewage draining exit A (12) is provided with in water inlet (1) side, sewage draining exit B (11) is provided with between two-layer filter screen, the housing (5) of delivery port (8) side is provided with backwash water inlet (4), this backwash water inlet (4) is at least arranged at the opposite side of the relative housing (5) of sewage draining exit between two-layer filter screen, namely this backwash water inlet (4) is at least arranged at the opposite side of the housing (5) relative with sewage draining exit B (11).
Further, the filter screen of above-mentioned at least two-layer different size preferably forms single filter element, in described housing (5), be provided with plural filter element.
Compared with prior art, the present invention has the function that can realize composite filtering and carry out backwash respectively, operation and use and be convenient to realize Automated condtrol, when not opened filter, can realize the advantages such as backwash.
