Efficient feces separation device of pond circulating water system

Abstract

The invention relates to an efficient feces separation device of a pond circulating water system. By means of the design of a conical dirt collection pond and a flow guide notch, the device effectively improves the swirling flow effect, so that solid waste finally settles in the dirt collection pond; an insertion pipe and a dirt discharge pipe form a communicating vessel which can control whether feces in the dirt collection pond can flow into a dirt discharge pond or not. The device is simple in structure, can effectively discharge residual bait and feces in a breeding tank, and can effectively solves the problems that residual bait and feces settlement causes ammonia nitrogen accumulation and harmful bacterium breeding and accordingly normal growth of bred objects is affected or even the bred objects are dead.

Description

technical field [0001] The invention relates to an aquaculture device, in particular to a high-efficiency excrement separation device for a pond circulating water system. Background technique [0002] At present, as people pay more and more attention to health, the demand for high-quality protein is gradually increasing. Compared with livestock meat, fish meat is tender, delicious and nutritious, and fish meat contains less fat, and unsaturated fatty acids account for most of the fatty acids contained in it, which is more beneficial to human body's digestion and absorption. Therefore, the demand for fish meat is increasing, but due to limited marine resources, relying on fishing can no longer meet the needs of society. Therefore, the development prospects of the world's aquaculture industry are very promising. China is the world's largest aquaculture country, accounting for about 70% of the world's total aquaculture, and the total aquaculture output maintains an annual grow...

Problems solved by technology

Although there are many large-scale filtration facilities and solutions in industrial wastewater treatment, these facilities or solutions are rarely used in aquaculture due to interference with aquaculture production and high prices. At present, they mainly rely on natural settlement at the end of the aquaculture tank area, and use water pumps to discharge solid waste

It is an economical and environmentally friendly method to naturally settle fish manure and residual bait in a specific area (sewage collection area) by gravity. However, during the operation of the water pump, it is easy to cause solid waste to be broken and stirred up and difficult to separate.
