Aquaculture tail water filtering system

Abstract

The invention provides an aquaculture tail water filtering system which comprises a water inlet pipeline, a front primary filtering mechanism, a three-way pipeline and two filtering mechanisms. Each filtering mechanism comprises a rack, a filter screen, a water inlet assembly, a collecting tank, a water collecting tank and a rotary driving assembly. The rotary driving assemblies are started to drive the filter screens to rotate, impurities on the filter screens can be removed through centrifugal force, the impurities are thrown into the collecting tanks, and therefore the filtering effect is improved by cleaning the filter screens. Water passing channels are formed in rotating shafts, a water pump pumps water in a second water tank into a first water tank, the water passes through the water passing channels and then is sprayed out from water spraying units, so that the water is sprayed out from inside to outside in the filter screens to effectively clean impurities attached to the surfaces of the filter screens, and meanwhile, the structure can also be used when the rotating shafts drives the filter screens to rotate, and the cleaning of the filter screens is synchronously enhanced by centrifugal force and water spraying.

Description

technical field [0001] The invention relates to the technical field of agricultural water pollution control, in particular to an aquaculture tail water filtration system. Background technique [0002] my country's aquaculture is developing towards high-density and intensive industrial farming, such as cage culture in sea areas and indoor recirculating aquaculture. This type of aquaculture is artificially controlled on the basis of high-density aquaculture. In order to achieve high-yield and high-efficiency production goals. In the breeding process, residual bait and feces are the main pollution sources of industrial aquaculture water. They should be removed in time in the water treatment process. Quick and effective removal of these residual bait and feces is the core of industrial aquaculture water treatment technology. question.
