Pollutant suction device of filter for agricultural irrigation

Abstract

The invention discloses a pollutant suction device of a filter for agricultural irrigation. The pollutant suction device comprises a pollutant suction pipe and a plurality of high-pressure suction nozzles, wherein the plurality of high-pressure suction nozzles are uniformly fixed on the outer wall of the pollutant suction pipe and communicated with the pollutant suction pipe; high-pressure spray nozzles are formed in the plurality of high-pressure suction nozzles and can be used for spraying out high-pressure water stream; the high-pressure spray nozzles are concentric with the high-pressure suction nozzles; a high-pressure pipe concentric with the pollutant suction pipe is arranged in the pollutant suction pipe; the high-pressure spray nozzles are all communicated with the high-pressure pipe; the high-pressure pipe can obtain the high-pressure water stream from a high-pressure pump. According to the pollutant suction device, the high-pressure spray nozzles concentric and coaxial with the high-pressure suction nozzles are arranged in the high-pressure suction nozzles of an original pollutant suction device, the high-pressure water stream in the high-pressure spray nozzles can be sprayed out to the interior of a fine filter net for thoroughly washing the two surfaces of the filter net, and scales are sucked by the suction nozzles at the moment when being washed away by the high-pressure spray nozzles; through the improvement, the spraying and sucking operations can be carried out at the same time, so that the pollutant suction capability is remarkably improved.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a sewage suction device for a filter used in agricultural irrigation. Background technique [0002] When irrigating crops, a filter is required to filter the irrigation water. Due to the poor water quality in some areas and the long-term operation of the equipment, the inner surface of the filter screen has a lot of fouling and cannot pass through the high-pressure nozzle. The impact force separates it from the inner surface of the filter screen, so that the suction nozzle cannot suck the fouling into the sewage pipe, and because the high-pressure nozzle and the suction nozzle are not in the same position, the fouling washed away by the powerful jet from the high-pressure nozzle will be washed away later. It reattaches to the inner surface of the filter screen within tens of seconds or even a few seconds, causing some of the accumulated dirt to reattach to the surface of th...

[0002] When irrigating crops, a filter is required to filter the irrigation water. Due to the poor water quality in some areas and the long-term operation of the equipment, the inner surface of the filter screen has a lot of fouling and cannot pass through the high-pressure nozzle. The impact force separates it from the inner surface of the filter screen, so that the suction nozzle cannot suck the fouling into the sewage pipe, and because the high-pressure nozzle and the suction nozzle are not in the same position, the fouling washed away by the powerful jet from the high-pressure nozzle will be washed away later. It reattaches to the inner surface of the filter screen within tens of seconds or even a few seconds, causing some of the accumulated dirt to reattach to the surface of the filter screen before it can be sucked by the suction nozzle. The sucking effect has a certain influence, which greatly reduces the sewage suction and sewage discharge capacity
