Aquaculture device with roundabout circulating water for shrimps

Abstract

The invention discloses an aquaculture device with roundabout circulating water for shrimps comprising a pond; a water treatment device is installed at one end of the pond; multiple water body separating walls are installed inside the pond; the pond is divided into an aquaculture water channel comprising multiple water flow channels by the water body separating walls; the water flow channels are communicated end to end successively; a water inlet pipe of the water treatment device is installed at one end of the aquaculture water channel; a water outlet pipe of the water treatment device is installed at the other end of the aquaculture water channel; a feeding device is installed in the water flow channel at the middle of the pond; an ejection device which can eject material in a feeding tray out of a discharging seat is installed on a floating platform; a feeding mechanism which can continuously provide material to a storage barrel is also comprised; The purpose of the invention is to overcome the deficiency of the prior art and to provide a aquaculture device with roundabout circulating water for shrimps which has simple structure, is capable of keeping good condition of water quality and water oxygen content, and has good cultivation effect, good bait dispersibility, and wide feeding scope.

Description

technical field [0001] The invention relates to a circuitous circulation water shrimp cultivation facility. Background technique [0002] Pond culture is one of the main forms of aquaculture. Since the 1970s in China, fish pond culture, shrimp and crab pond culture, and aquaculture fry pond cultivation have flourished successively in China. The aquaculture water body is about 10 billion cubic meters , Such a large scale of farming has made great contributions to the development of my country's aquatic economy. Existing aquaculture ponds are mainly rectangular in shape with a uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds that are equipped with water stirring and aeration machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very low. The corners o...

Problems solved by technology

Existing aquaculture ponds are mainly rectangular in shape with uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds equipped with water-stirring and oxygen-increasing machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very low. The corners of the pond far away from the inlet and outlet often become dead corners, the water quality in the pond is not uniform, and the local area is often hypoxic conditions, the cultured organisms cannot obtain a suitable growth environment, diseases frequently occur, the production speed is slow, and even the breeding capacity decreases, and the production efficiency is low

[0003] In addition, in order to improve the efficiency of breeding work, feeding devices are generally used when feeding feed to the farming area. Due to design defects, the current feeding devices on the market have poor dispersion of bait when feeding, and fish and shrimp need to be concentrated. eat in a small area

it's bad for feeding
