Sewage clearing system for penaeus vannamei aquaculture

Abstract

The invention discloses a sewage clearing system for penaeus vannamei aquaculture. A plastic greenhouse covers the top end of an aquaculture pond body, supporting frames are fixedly arranged on left and right sides of the top end of the aquaculture pond body, left and right ends of a lead screw are arranged on the supporting frames at left and right ends through a first bearing and a second bearing respectively, the end of the lead screw is fixed to an output shaft of a driving motor through a coupler, and a lead screw nut is arranged on the lead screw and in meshed connection with the lead screw. An upper fixing part is fixed to the bottom end of the lead screw nut, a lower fixing part is fixedly arranged at the top end of a fishing net, and a fixing bolt sequentially penetrates the upperfixing part and the lower fixing part to fix the fishing net to the bottom end of the lead screw nut. The bottom end of the aquaculture pond body is provided with a sedimentation slope, a sewage discharging pipe is arranged at the bottom end of the sedimentation slope, the other end of the sewage discharging pipe extends into a sedimentation tank, and the sewage discharging pipe is serially connected with a sewage discharging pump. The sewage clearing system has advantages of energy saving and environmental friendliness, and a great growing environment is provided for penaeus vannamei.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pollution cleaning system for the cultivation of Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three most productive shrimps in the world today. The meat of Penaeus vannamei is delicious, and the processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18-32°C. , can grow under the condition of salinity 1-40‰, and is an excellent desalinated cultured species. In the prior art, there will be a large amount of floating algae in the Penaeus vannamei culture pond, which needs to be cleaned regularly, and the manual cleaning method is time-consuming and laborious. A decontamination system for Penaeus vannamei culture that can solve the above problems still needs further research and development. Contents of the invention [0003] The purpose of the present invention is to provide a decontamination system for ...
