Non-disturbance temporary rearing and purification system for shellfishes

Abstract

The invention discloses a non-disturbance temporary rearing and purification system for shellfishes. The system comprises a rearing pond, a biological packet, an air lift part and a settling part. Therearing pond is provided with a conical bottom; a water sucking hole is formed in the center of the bottom; the biological packet is provided with a sealed cavity; the biological packet is positionedabove the rearing pond; the biological packet is filled with a biological filtering material; an automatic air pressure adjusting valve is arranged at the top of the biological packet; a water inletis formed in the top of the biological packet; a water outlet tube is arranged at a side wall or the bottom of the biological packet; the air lift part comprises an air supply end, an aeration head I,an aeration head II and a lift tube; the upper end of the lift tube extends into the water inlet of the biological packet; the lower part of the lift tube is formed into a shape into which the aeration head I and the aeration head II are contained appropriately; the air supply end is used for supplying aeration air to the aeration head I and the aeration head II respectively; the settling part comprises a water drainage tube and a gradient diameter variation settling tube; and the water sucking hole, the water drainage tube, the gradient diameter variation settling tube and the bottom of thelift tube communicate in sequence. By adopting the equipment, no extra equipment or power is needed to enable a water body to circulate and flow while expected dissolved oxygen concentrations in the rearing pond are met, residual baits and excrement can be collected for water quality purification, water flows are not disturbed since no direct pond bottom aeration exists in the rearing pond, the residual baits and excrement and suspended solids can be easily settled to the pond bottom and discharged along with the water flows, and the water quality deterioration time can be shortened while convenience in cleaning is achieved.

Description

[0001] This application is a divisional application for the application number 2017105573751, the application date is July 10, 2017, and the invention name is "integrated equipment for aquaculture and purification". technical field [0002] The invention relates to the technical field of aquaculture, in particular to an undisturbed shellfish temporary breeding purification system. Background technique [0003] At present, in the traditional industrialized aquaculture production process, in order to supply the oxygen in the water body in the pond body, the method of oxygenation and aeration is mostly used, and the air pipe placed on the upper part of the aquaculture pond is divided into thin tubes to supply air to each pond body . The entire breeding water surface is aerated in many places, and the broken air bubbles on the water surface increase the air-water interface, resulting in high humidity in the breeding workshop. At the same time, this is also an important aspect t...

Problems solved by technology

On the one hand, this large-scale circulation route requires electricity to provide circulation power, and on the other hand, it needs to consume more energy to maintain a constant water temperature

Project construction investment is high, and it is not conducive to energy saving
