Problems solved by technology

However, the main disadvantage of the curved screen is that it is easy to be blocked by particles, and it needs to be manually cleaned regularly. When the breeding load is high, it even needs to be washed once an hour to maintain the normal operation of the equipment. The efficiency of manual washing is not high, and it consumes more water.

Abstract

The invention discloses arc screen filtering equipment capable of being automatically cleaned, which comprises an overflow tank (1), an arc screen (2), a sewage collection tank (3) and a clear water collection tank (4), wherein arc guide rails (7) which are matched with the arc screen (2) are arranged on the upper side and the lower side of the arc screen (2) respectively; slide blocks (11) are arranged on the two arc guide rails (7) respectively and are connected with a motor (13) through a crank rocker (17); the motor (13) is used for driving the slide blocks (11) to slide on the arc guide rails (7) through the crank rocker (17); and a water spray pipe (14) is arranged between the slide blocks (11) and is provided with a high pressure water inlet port (20) and a row of nozzles (15) facing towards the arc screen (2). According to the arc screen filtering equipment capable of being automatically cleaned, the back face of the arc screen can be automatically washed, and the washing effect and the automation degree of the arc screen can be improved under the conditions of water saving and energy saving.

Description

technical field [0001] The invention relates to equipment for filtering and treating waste water, in particular to a filtering equipment capable of automatically cleaning curved screens. Background technique [0002] The curved sieve was first used in ore separation and is a metal mesh structure device for separating particles. The physical filtration methods in the domestic closed circulating aquaculture system are mainly based on various screens, and the curved screen is one of the most favored by aquaculture enterprises, and has further replaced the traditional drum filter and drum Type filter trend. The curved screen has the characteristics of simple structure, high filtration efficiency, no need for power, small space occupation, and low maintenance. However, the main disadvantage of the curved screen is that it is easy to be blocked by particles, and it needs to be manually cleaned regularly. When the breeding load is high, it even needs to be washed once an hour to ...
