Movable pollution discharge cover for intensive shrimp pond

Abstract

This invention relates to an intensive shrimp pond with a mobile sewage enclosure. It includes operating set (1), operating leverage (2), topiary resistance shield (3), fencing (4) and the base (5); Operating rod (2) top connects to operating set (1) the cross bar; Central welds to resistance shield (3); Fencing (4) has two of up and down ring fixed coil (4-1, 4-2), The fence vertical welds to fixed coil (4-1, 4-2); the lower fixed coil (4-2) welds a truss to three (4-3), truss central connects to operation of the bar (2) the bottom welding; compressive shield (3) welds to the lower part the fence (4) the top; the lower fixed coil (4-2) welds three to six fixed card (4-4); the base (5) reserves socket (5-1); cradle simultaneously reserves card mouth and the inner wall of the entrance arch 45 degrees (5-2). The advantage of this invention is simple structure, low cost, corrosion resistance, anti-hypertension, secure and efficient, easy to maintain, mobile.

Description

technical field [0001] The invention relates to a mobile sewage discharge cover for an intensive shrimp pond. Background technique [0002] Shrimp farming is a pillar industry of aquaculture. The new model of shrimp farming—intensive farming with water (also known as high-level pond farming) has gradually replaced the extensive tidal farming model. The water-lifting intensive culture pond (prawn high-level pond) is generally square or round, with an area ranging from 4 to 10 mu, and an effective water depth of about 2m; the shrimp pond adopts cement slope protection, and an anti-seepage geomembrane is laid on the bottom of the pond; the center of the shrimp pond is designed with Sewage well. During the breeding process, due to the installation of an oxygen-increasing water truck, the water body is kept rotating while providing enough dissolved oxygen in the water body, so that the residual bait and feces are concentrated in the center of the shrimp pond, and then discharged...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the existing intensive shrimp pond central sewage well, such as high cost, bulky screen, cumbersome cleaning and screen replacement operations, poor sewage discharge effect, poor safety performance, and affecting the operation of shrimp harvesting, and to provide a sewage treatment system that does not require sewage discharge. Well, a mobile sewage cover for intensive shrimp ponds with simple structure, low cost, corrosion resistance, high pressure resistance, safety and high efficiency, and easy maintenance
