Rotational flow type sand-removing multi-grade filtering device for agricultural irrigation

Abstract

The invention discloses a cyclone-type sand removal multi-stage filter device for agricultural irrigation, which comprises an upper tank body, a lower tank body, a conical sand settling bucket, a sand discharge device, an overflow pipe, a filter cylinder, a rotating cylinder and a moving annular cylinder ;Due to the filtering effect of sand and stone filter plates, activated carbon filter plates, light ceramsite filter plates of biological filter materials and hollow spherical magnesium oxide adsorption plates on water, the impurity content in the discharged water is less, avoiding the traditional rivers, etc. The pollution problem caused by direct irrigation of water can conveniently turn out the first filter layer, the second filter layer, the third filter layer and the fourth filter layer to facilitate the replacement of the filter plate. When the filter plate is replaced, twist Rotate the cylinder so that the directions of the magnetic south pole and the magnetic north pole of the first magnet and the second magnet adjacent up and down are opposite, and the two moving annular rings are in contact with each other, which prevents water from passing through the first filter layer, the second filter layer, and the second filter layer. The situation where a large amount of overflow occurs due to the gap at the joint between the third filter layer and the fourth filter layer.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a cyclone type sand removal multi-stage filter device for agricultural irrigation. Background technique [0002] As the country's economic lifeline and major water user, agriculture has long been using traditional and backward flood irrigation due to reasons such as ideology, capital, and technology. However, with the increasing contradiction between the shortage of water resources and the increase in water demand Intensified, flood irrigation is gradually being replaced by modern water-saving irrigation models that focus on precise irrigation. [0003] Modern scientific irrigation technology can effectively use limited water resources. It is mainly divided into micro-spray and drip irrigation. However, since micro-spray and drip irrigation need to release water through micro-nozzles or capillary tubes, there is a certain degree of water purity. It is required th...

[0003] Modern scientific irrigation technology can effectively use limited water resources. It is mainly divided into micro-spray and drip irrigation. However, since micro-spray and drip irrigation need to release water through micro-nozzles or capillary tubes, there is a certain degree of water purity. It is required that the water should not contain more sand impurities, otherwise it will easily block the micro nozzle or capillary, so a sand removal and sand removal filter device for agricultural irrigation is needed
