Abstract

The invention belongs to the field of aquaculture engineering, and particularly relates to a pore-adjustable turntable type bottom blowdown device for a shrimp breeding pond. The two ends of a bend are communicated with one end of a drainage pipeline B and a drainage pipeline A respectively, and the bottom of the other end of the drainage pipeline B passes through a threaded hole formed in a pinchplate and is connected with a chassis, and the other end of the drainage pipeline B is provided with a through hole, the outer surface of the portion between the two ends of the drainage pipeline B is provided with an external threaded section, and the pinch plate forms a helical pair with the external threaded pipe through the threaded hole; the chassis is placed on the bottom surface of the shrimp breeding pond, through the helical pair formed by the pinch plate and the external threaded plate, the pinch plate is rotated to achieve lifting relative to the drainage pipeline B, and the size of a sewage discharge pore formed between the lower end of the outer edge of the pinch plate and the bottom face of the shrimp breeding pond is adjusted; the outer edge of the pinch plate is provided with a living shrimp anti-escape tooth for preventing living shrimps from getting close to the sewage discharge pore. According to the size of the living shrimps, the size of the sewage discharge porein the bottom of the shrimp breeding pond can be adjusted conveniently, sewage discharging is facilitated while the living shrimps are prevented from escaping.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to a bottom sewage discharge device for a turntable shrimp pond with adjustable pores. Background technique [0002] In order to efficiently discharge dirt such as shrimp shells, dead shrimp, and residual bait feces during the prawn breeding process, an intermittent return water process (such as disclosed on September 22, 2017, the publication number is CN107182893A, and the invention name is "a circulating water Intermittent return water device and its return water process for aquaculture system"). When adopting this technology to raise shrimps, when the intermittent return water is turned on, the live shrimps will be sucked out into the live shrimp escape prevention basket along with the shrimp shells and dirt due to the strong suction of the sewage suction port (see 2019 for the live shrimp escape prevention basket) It was published on March 12, 2010, the publication numbe...
