Culture pond sewage discharge device

Abstract

The invention discloses a culture pond sewage discharge device, and relates to the technical field of sewage discharge devices. The culture pond sewage discharge device comprises a sewage collecting assembly, a waterwheel aerator and a sewage discharge pipe, wherein the sewage collection assembly is placed in a culture pond and communicates with an opening in the bottom surface of the culture pond; the lower end of the sewage collection assembly is fixedly connected with the inner bottom surface of the culture pond; one end of the sewage discharge pipe is connected with the opening in the bottom surface of the culture pond and communicates with an inner cavity of the sewage collection assembly; the other end of the sewage collection assembly extends in the direction away from the culture pond; the end, away from the culture pond, of the sewage discharge pipe is detachably connected with a seal plug; the seal plug is used for opening and closing the sewage discharge pipe; the waterwheelaerator is detachably fixed in the culture pond, located between the outer wall of the sewage collection assembly and the inner wall of the culture pond, and used for enabling a water body to drive sewage to move in the direction close to the sewage collection assembly and collecting the sewage in the sewage collection assembly; and fishes cannot enter the sewage collection assembly. The culturepond sewage discharge device is capable of effectively cleaning sundries in the culture pond, and is convenient to use and low in production cost.

Description

technical field [0001] The invention relates to the technical field of sewage discharge devices, in particular to a sewage discharge device for aquaculture ponds. Background technique [0002] my country's aquaculture industry ranks first in the world, and my country's aquaculture industry is showing a trend of increasing year by year. In 2018, the total output of aquatic products in the country was 64.5766 million tons, an increase of 0.19% over the previous year, of which the aquaculture output was 49.9106 million tons, accounting for 77.29% of the total output. A year-on-year increase of 2.35%. With the continuous growth of my country's aquaculture industry, the cleaning of actual aquaculture ponds is a difficult problem. There are various sundries in the aquaculture water, such as fish feed, excrement, and various sundries from outside the aquaculture water will accumulate in the aquaculture pond, resulting in the enrichment of various harmful factors in the water.

Problems solved by technology

There are various sundries in the aquaculture water, such as fish feed, excrement, and various sundries from outside the aquaculture water will accumulate in the aquaculture pond, resulting in the enrichment of various harmful factors in the water. Cause the outbreak of fish disease, and in severe cases, it can cause fish death, so it is urgent to clean up the dirt in the breeding pond in time

[0003] A part of the existing breeding ponds is directly artificially discharged, that is, the fish is fished out and then pumped and desilted, which wastes labor, has poor cleaning timeliness, and is destructive to the environment to a certain extent, and the other part uses high-cost Water quality filter, the actual promotion cost is relatively high
