Three-dimensional wall-attached water absorbing, filtering, blowdown and self-cleaning device for fish culture system with flow water tank

Abstract

The invention discloses a three-dimensional wall-attached water absorbing, filtering, blowdown and self-cleaning device for a fish culture system with a flow water tank. The three-dimensional wall-attached water absorbing, filtering, blowdown and self-cleaning device comprises a feeding tank body, wherein a gas and water spraying dirt-removal and cleaning device, a water and dirt separation self-cleaning rotary filtering cylinder, a blowdown water filtering conveying belt, a wall-attached dirt suction pipe, and a three-dimensional wall-attached dirt suction tank are sequentially arranged on the feeding tank body from top to bottom; the water and dirt separation self-cleaning rotary filtering cylinder is arranged on a side plate of the feeding tank body through a motor; a dirt outlet of thewall-attached dirt suction pipe extends into the part, near the lower end of the cylinder circumference, of the interior of the water and dirt separation self-cleaning rotary filtering cylinder. To respond to the national advocating command of reducing ecological environments of large rivers and large lakes, after purse seines of rivers and lakes for culture are removed, people can provide healthand high-yield facility guarantee so as to enhance the effect of culture of artificial fish tanks. The three-dimensional wall-attached water absorbing, filtering, blowdown and self-cleaning device has the advantages that the water and dirt in a water body in a flow water feeding tank are performed with three-dimensional wall-attached suction by a physical method, and are finely separated, and thewater and dirt separating device is automatically cleaned, so that the generation of pollution of the circulating water body and the diseases of the fed fishes in the tank can be prohibited; the structure is innovative and reasonable, and the convenience and effectivity in use are realized.

Description

technical field [0001] The invention relates to the technical field of filtration and sewage discharge equipment, in particular to a three-dimensional wall-attached water absorption, filtration and sewage discharge self-cleaning device for a fish farming system in a running water tank. Background technique [0002] At present, when fish are cultured in running water tanks, the pollutants are basically discharged in a straight row with horizontal and natural flow of water. As a result, a large amount of fish feces and remaining feed float to the waters outside the tank with the water flow, and the tanks are reared intensively. , concentrated discharge outside the tank, the rapid deterioration of the circulating water outside the tank, and lead to a vicious cycle of water pollution in the tank, and eventually forced to stop production. It is still blank to use a three-dimensional wall-attached water-absorbing filter to discharge sewage and automatically clean the sewage discha...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a three-dimensional wall-attached water-absorbing, filtering, and sewage self-cleaning device for the fish culture system of the running water tank, which solves the problem of the rapid deterioration of the circulating water outside the tank caused by the concentrated discharge of sewage outside the tank when the fish are cultured in the running tank Then it leads to the vicious circle of water pollution in the tank
