Biological floccule filtering equipment applied to aquaculture

Abstract

The invention discloses biological floccule filtering equipment applied to aquaculture, belongs to the technical field of biological filtration. According to the biological floccule filtering equipment applied to aquaculture, filled layers formed by a plurality of annular frames arranged inside and outside are filled with a biological floccule layer so as to play roles in supporting and limiting the biological floccule layer, when a water body flows through the biological floccule layer, the water body cannot shift due to excessive water flow impact force, meanwhile, a plurality of groups of nozzles corresponding to the positions of the filled layers are distributed inside and outside the bottom of a conical spray head, the water body fully diffuses onto the annularly distributed biological floccule layer, and the contact area of the biological floccule layer and the water body is effectively enlarged, so that the filtering effect is effectively improved, meanwhile, the water body is stirred through the cooperation of a rotating stirring pipe and an aeration pipe, namely, the filtering adsorption efficiency is effectively improved, meanwhile, the rapid and sufficient diffusion of gas in the aeration pipe is effectively realized under the rotating operation of the stirring pipe, and nutrients are supplied to the biological floccule layer.

Description

technical field [0001] The invention relates to the technical field of biological filtration, and more specifically relates to a biological floc filtering device applied to aquaculture. Background technique [0002] In the process of aquaculture, it is necessary to use a filter device to circulate and filter the aquaculture water. The filter using biofloc as the filter material is one of them. Biofloc refers to the organisms in the aquaculture water mainly composed of aerobic microorganisms. And inorganic bodies, the aggregates formed by bioflocs are generally formed by the mutual flocculation of bacteria, phytoplankton, mail debris and some inorganic substances, and the nutrient waste such as residual bait and feces in the breeding system can be degraded and converted into edible waste. Nutrients for the reproduction of planktonic algae to achieve the purpose of fertilizer and water in disguise. At present, the existing biofloc filters often fill the filter container with ...

Problems solved by technology

[0004] The reference document adds a screen with a certain mesh number in the inner cylinder to improve the filtering effect, but there are still some defects: in the reference document, by filling the inner cavity of the filter inner cylinder with biochemical filter balls, aquatic product cultivation The water in the pool enters the filter inner cylinder through the water inlet pipe, and the water inlet pipe only has one water outlet. It is often difficult to fully contact the water body with the filled biochemical filter balls, that is, the biochemical filter balls located at the top and at the edge are difficult to be used. At the same time, the space loaded by the filter ball is relatively large, that is, the filling thickness of the biochemical filter ball is relatively large, and it is often not easy to quickly filter the water body, and the water body has a certain gravity, and it is difficult for it to spread rapidly around in the process of flowing downward. Larger, more affecting the filtration efficiency of water
