Water-circulated fishery multi-functional pond

Abstract

The invention relates to a fishery breeding device, in particular to a water-circulated fishery multi-functional pond which can purify water quality and enable water to be circulated for use. A communicating pipe which communicates with an inner bin and is near the bottom of the inner bin is arranged on the hopper wall of a conical hopper, and a sewage collecting and precipitating bin is arrangedat the bottom of the conical hopper; a circulating water pump is arranged outside a pond body, a water inlet pipe of the circulating water pump communicates with the bottom of the inner bin, and a water outlet pipe communicates with the upper part of the pond body; and biological fillings are arranged in the inner bin. According to the water-circulated fishery multi-functional pond disclosed by the invention, in the breeding process, excrement and urine of aquatic products and feed residues slide downwards into the sewage collecting and precipitating bin along the conical hopper; besides, water in the inner bin is circulated into the pond body from the water outlet pipe by the circulating water pump, because the water outlet direction is tangent to the inner wall of the pond body, the water can be pushed to move to form a whirlpool, and sewage collection is convenient; and in addition, the biological fillings are also arranged in the inner bin and can achieve better purifying effects on the water quality, so that the circulated water quality is well maintained, and growth of the aquatic products is convenient.

Description

technical field [0001] The invention relates to a fishery cultivation device, in particular to a fishery multifunctional pool with circulating water capable of purifying water quality and circulating water. Background technique [0002] In fish farming, the main methods are pond culture, greenhouse culture and indoor factory culture, and the breeding density increases successively. Among them, indoor factory culture is the development trend. Its main characteristics are the realization of water quality control and high-density culture. It is a kind of Intelligent high-yield farming model. In the conventional pond and greenhouse breeding process, due to the large volume of the water body, it is difficult to collect and discharge the feces and feed residues of fish and shrimp. The continuous accumulation will pollute the water body and affect the water quality. Various methods must be used to adjust the water quality To meet the growth of fish and shrimp, the process is cumbe...

AI Technical Summary

Problems solved by technology

This method wastes a lot of manpower and material resources, wastes a lot of water resources, the breeding density is low, and the risk is high, which is not conducive to the expansion of intensive farming scale.

Every breeding method needs to ensure that the concentration of dissolved oxygen in the water meets the growth requirements of fish and shrimp, especially high-density farming, once the lack of oxygen is easy to cause economic losses, if the power is cut off, the main way of increasing oxygen currently used is a generator Power generation to start the aerator, the second is to directly pass the oxygen cylinder into the pool, and the third is to use the oxygen-producing chemical reagents on the market for emergency response. These three methods require a certain amount of time to respond
