Embodiment 1

[0016] Embodiment 1: refer to figure 1 , figure 2 , is a structural schematic diagram of Embodiment 1 of the present invention, including a cylindrical housing (5) provided with a water inlet (1) and a water outlet (8), the water inlet (1) is located on the upper part of the housing (5), and the housing Between the water inlet (1) and the water outlet (8) in (5), two layers of filter screens of different specifications are arranged in concentric circles, i.e. a large size filter screen (6) and a small size filter screen (7). The standard filter screen (6) is arranged on the side of the water inlet (1) in the center of the housing (5), and the small size filter screen (7) is arranged on the periphery of the large size filter screen (6), that is, on the side of the water outlet (8). At the same time, a sewage outlet is provided on the side of the water inlet (1) and between the two layers of filter screens, that is, a sewage outlet A (12) is provided on the side of the water i...

Embodiment 2

[0017] Embodiment 2: refer to Figure 3 ~ Figure 5 , is a structural schematic diagram of Embodiment 2 of the present invention. Compared with Embodiment 1, the difference of this embodiment is that: the two layers of filter screens of different specifications form a single filter unit, and in the housing ( 5) A plurality of filter units are arranged inside, and each filter unit is provided with a water inlet (1) and two sewage outlets.

Embodiment 3

[0018] Embodiment 3: refer to Figure 6 , is a structural schematic diagram of Embodiment 2 of the present invention. Compared with Embodiment 2, the difference of this embodiment is that a layer of filter net is also arranged on the periphery of a plurality of filter units composed of two layers of filter nets of different specifications. .

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 [0001] The invention relates to a filter, in particular to a water purification filter for a water-saving irrigation system. Background technique [0002] my country's water resources are very short, and the per capita water resources are only a quarter of the world's average level, and agriculture is a large water user. Therefore, it is imperative to accelerate the development of agricultural water conservation. [0003] Some research results of domestic self-cleaning filters can complete the automatic cleaning of filtered dirt and impurities to a certain extent, but the cleaning mechanism or transmission mechanism needs to be driven by an external force, usually an electric motor, or a larger sewage chamber needs to be added to increase the filtration efficiency. The cost of manufacturing and using the appliance. [0004] Therefore, a filter with simple manufacture, simple structure, multiple filtering and backwashing in the casing, a pressure-resistant st...
