Embodiment

[0027] The top plate 4 and the blowdown casing 6 are of an integral structure, and the diameter of the blowdown casing 6 is equal to the diameter of the blowdown pipe of the prawn farming system. The chassis 10 is a cruciform structure, such as figure 2 shown. The lower end of the guide pipe 2 is riveted with the chassis 10, and the chassis 10 is fixed on the bottom of the shrimp pond center sewage outlet. Be provided with a plurality of drainage holes 7 in the area above 20cm from the lower end of the sewage casing 6, the diameter of the drainage holes 7 is less than the width of the shrimp body, and the drainage holes 7 are used for daily drainage. An inner disc 5 for stabilizing the sewage sleeve 6 is provided at a distance of 1\3 pipe lengths from the upper end of the sewage sleeve 6 .

[0028] The working principle of the present invention is:

[0029] When blowing down, firstly open the aeration pipe 8 and inflate the blowdown casing 6 through the air charging port 9...

Abstract

The invention relates to a blowdown device in a prawn breeding system, in particular to a gas lifting type decontamination device suitable for prawn indoor industrial culture.The gas lifting type decontamination device suitable for prawn indoor industrial culture comprises a guiding pipe, a top tray, a blowdown sleeve, an aeration pipe and a base plate, wherein the base plate is arranged at the lower end of the guiding pipe and installed on a blowdown port of the prawn breeding system, the guiding pipe is sleeved with the blowdown sleeve which can slide up and down along the guiding pipe, water drainage holes are formed in the position close to the lower end of the blowdown sleeve, the aeration pipe is arranged at the lower end of the blowdown sleeve in the peripheral direction, and the top tray is arranged on the top of the blowdown sleeve and further provided with an inflating port.Bubbles overflow to disturb living prawns so that the prawns can leave the blowdown port and cannot be affected by sewage, and meanwhile, by lifting the blowdown port through gas, dead prawns, residual feed and faeces in a prawn pond are fast removed.

Description

technical field [0001] The invention relates to a sewage discharge device of a prawn cultivation system, in particular to an air lift type decontamination device for an indoor factory cultivation of a prawn. Background technique [0002] Since the domestic introduction of Penaeus vannamei with high disease resistance, fast growth and strong tolerance in 2000, shrimp farming has developed rapidly and has played a very important role in my country's coastal aquaculture industry. Traditional shrimp farming is pond farming; but with the development of technology, more and more recirculating aquaculture systems have also begun to be used for shrimp farming. Regardless of the traditional pond culture or the current recirculating aquaculture, there are problems such as difficult sewage discharge, large labor demand, great stress on live shrimp from sewage discharge, and easy escape of live shrimp. [0003] At present, the sewage discharge of shrimp breeding ponds still requires pe...
