Agricultural shaftless rotary drum filter

Abstract

The invention discloses an agricultural shaftless rotary drum filter, comprising a case, a spraying assembly, a micro-filtration rotary drum, a water inlet pipe, a filter residue collecting tank, a pulley bracket and a motor, wherein the micro-filtration rotary drum placed in the middle part of the case is supported by the pulley bracket arranged out of the rotary drum; the spraying assembly is mounted above the rotary drum and comprises a spraying pipe and a plurality of nozzles, and the spraying pipe is connected with a water pump arranged below the case through a pipeline; the filter residue collecting tank is arranged inside the rotary drum, both ends of the filter residue collecting tank are fixed on the outer wall of the case, and one of the ends is a sewage outlet; and the water inlet pipe is arranged below the filter residue collecting tank and has a plurality of water outlets. During automatic cleaning, the motor located at the top of the case drives the filter micro-filtration rotary drum to rotate, high-pressure water sprayed by the spraying assembly flushes filter residues accumulated on a filter screen, and the filter residues fall into the filter residue collecting tank and are then discharged. The agricultural shaftless rotary drum filter of the invention has the advantages of low cost, convenient installation, high automation degree, energy conservation, stableoperation and simple maintenance, and provides a feasible solution for filtering of small agricultural production.

Description

technical field [0001] The invention relates to a filter device, in particular to a drum filter. Background technique [0002] The existing agricultural filter has the following disadvantages: first, the cost is high. Existing agricultural filters are designed for factory agricultural production, which not only cannot meet the needs of small-scale agricultural production, but also are expensive, making it difficult for small-scale agricultural producers to afford, making it difficult to improve existing production technology and efficiency. Then, continuous rotation and backwashing consume a lot of energy. Finally, the design is complex, difficult to replace, and time-consuming and labor-intensive to maintain. Contents of the invention [0003] The purpose of the present invention is to provide an agricultural filter, which has low manufacturing cost, does not need a central axis for the rotation of the micro-filter drum, runs stably, has high reliability, is easy to dis...
