Problems solved by technology

[0002] With the popularization and application of water-saving irrigation technology, water quality filters have also been developed on a large scale. The existing farmland water quality filtration treatment equipment is connected in series. First, the irrigation water is initially filtered through a centrifugal sediment filter. Then enter the laminated or mesh filter. The problem exposed by this filtering method is that the connection of the filtering equipment is complicated, the resistance is large, and the manufacturing cost is high. With the increase of the irrigation area, it is necessary to equip multiple sets of filters to meet the needs.

Embodiment Construction

[0017] figure 1 The main innovation of the combined filter for micro-irrigation shown is that the centrifugal sand-water separation chamber 2, which is mainly used for sediment filters, is combined with multiple sets of basket-type filter elements 2, and the filter is a cone-shaped package structure as a whole. , the filter element is arranged in the upper cone 13, and the centrifugal sand-water separation chamber and the sand collection tank 9 are arranged at the bottom, and the irrigation water enters the sand-water separation chamber 12 from the water inlet at the bottom, and the silt is centrifugally deposited into the sand collection tank 11. The filtered water enters the combined filter element 2 through the upper cone 13 and flows out from the water outlet 6 . This design method not only reduces the occupied area of ​​the filter, but also saves the manufacturing cost, so that the equipment cost is greatly reduced.

Abstract

A combined filter for the water-saving irrigation is composed of a centrifugal sand-water separating chamber with water inlet and outlet and a sand collector. It features that said centrifugal sand-water separating chamber has one or more filter cores. Its advantages are high filtered flow and low cost.

Description

technical field [0001] The invention relates to a combined filter for micro-irrigation, which is a matching part for micro-irrigation and sprinkler irrigation, belongs to the technical field of agricultural water-saving irrigation machinery filtering equipment, and is especially suitable for sandy water quality treatment of farmland micro-irrigation. Background technique [0002] With the popularization and application of water-saving irrigation technology, water quality filters have also been developed on a large scale.
