Pollutant collecting and draining system for circulation running water breeding field

Abstract

The invention discloses a pollutant collecting and draining system for a circulation running water breeding field. The pollutant collecting and draining system is mounted at the bottom of a running water breeding tank, and comprises a pollutant collecting and draining pipe, a tank body and two sets of pollutant scraping mechanisms, wherein the section of the pollutant collecting and draining pipeis C-shaped; the tank body comprises a first side plate and a second side plate which are in V-shaped arrangement at two ends of an opening in the axial direction of the pollutant collecting and draining pipe; the two sets of the pollutant scraping mechanisms are respectively located on the opposite surfaces of the first side plate and the second side plate, are in sliding connection with a firstsliding groove and a second sliding groove, and are used for scraping pollutants deposited on the first side plate and the second side plate into the pollutant collecting and draining system, and sealing the opening in the axial direction of the pollutant collecting and draining system. The structure of the pollutant collecting and draining system is optimized, so that pollutant collecting and draining treatment is convenient for the breeding tank; the pollutant scraping mechanism scrapes the pollutants into the pollutant collecting and draining pipe, and seals the opening in the axial direction of the pollutant collecting and draining pipe, so that one end of the pollutant collecting and draining pipe is connected with a water inlet of a pollutant draining pump, and the pollutants in thepollutant collecting and draining pipe can be sucked to appointed places to be treated. The pollutant collecting and draining system is high in efficiency, can thoroughly clean the pollutants at the lowest water quantity, and is good in pollutant collecting and draining effects.

Description

technical field [0001] The invention relates to the technical field of sewage collection and discharge in breeding tanks, and more specifically relates to a sewage collection and discharge system for circulating water farms. Background technique [0002] The running water aquaculture tank is used for aquaculture, and generally has a box structure, and the left and right ends are constructed of mesh plates or mesh ropes, through which water flow can pass. [0003] The sewage discharge system of the existing running water aquaculture tank generally sets a sewage collection area at the end of the aquaculture tank, and vertically sets a baffle plate about 1 meter above the bottom at the end of the sewage collection area, and then adopts a walking type suction to clean the sewage collection tank. Sewage suction, this kind of sewage system has a large amount of sewage collection and sewage discharge, low efficiency, and poor effect. Most of the sewage still enters the pond with th...
