Bulk flow and self-cleaning net type filter

Abstract

The present invention relates to a bulk flow and self-cleaning net type filter comprising a tank body, a power system, a control system and a filter chamber. The bottom of the tank body is provided with a water inlet, one side of the tank body is provided with a water outlet, and the top of the tank body is provided with a sewage draining exit and a power system, and a filter chamber connected with the power system, the control system and the water outlet respectively is arranged inside the tank body. The filter is characterized in that the filter chamber comprises a cuneate filter canister and a rotating stainless steel wire brush unit arranged in the cuneate filter canister; the cuneate filter canister is connected with the water inlet; the rotating stainless steel wire brush unit comprises central upper, middle and lower wire brush shafts that are connected to each other, and three sets of steel wire brushes that are arranged at the central brush shafts vertically; the upper and lower shafts of the wire brush are connected with the top and the bottom of the filter chamber respectively; every two steel wire brushes are at a 120 DEG angle to each other. The filter is advantageous in simple structure, sensitive self-cleaning control system and excellent sewage draining effect.

Description

technical field [0001] The invention relates to a filter device in agricultural water-saving irrigation equipment, in particular to a large-flow self-cleaning net filter. Background technique [0002] With the rapid development of modern agricultural water-saving irrigation technology, drip irrigation and sprinkler irrigation technology are being more and more widely used. The traditional agricultural irrigation water treatment screen filter has the advantages of simple structure, low manufacturing and use costs, and can be arbitrarily configured with filters of different pore sizes according to actual needs to achieve different filtering requirements. It is generally used as a secondary filter in the filter system. Stage or three stages of filtration, and most of them are small unit combinations to achieve flow rate, when the flow rate reaches 500m 3 For the filtration system above / h, the structure of the unit combined filter is too large, and the installation and use occ...

The traditional agricultural irrigation water treatment screen filter has the advantages of simple structure, low manufacturing and use costs, and can be arbitrarily configured with filters of different pore sizes according to actual needs to achieve different filtering requirements. It is generally used as a secondary filter in the filter system. Stage or three stages of filtration, and most of them are small unit combinations to achieve flow rate, when the flow rate reaches 500m 3 For the filtration system above / h, the structure of the unit combined filter is too large, and the installation and use occupy a large space. When realizing automatic backwashing, it is necessary to install a backwashing control valve in front of each unit filter, which makes the manufacturing cost too high. Therefore, design a structure with small volume, low operating cost, and flow rate up to 500m 3 / h or more, a large flow self-cleaning mesh filter capable of automatic backwashing is necessary
