Pond industrialized cultivation waste collecting device and method

Abstract

The invention provides a pond industrialized cultivation waste collecting device which is simple in structure, easy to operate and popularize and high in collecting rate. A flow guide groove is communicated with a water inlet in the side wall of a collecting cylinder, and the other end of the flow guide groove is communicated with a pond. A water pumping pipe extends in the axis direction of the collecting cylinder, and an inlet of the water pumping pipe is located at the bottom of the collecting cylinder. A water outlet is formed in the side wall of the collecting cylinder. The lowest part of the water outlet is higher than the highest part of the water inlet. The water outlet is communicated with the pond through a reflux tank. A guide plate is arranged above an aerating device on the lower portion in the pond. Gas released by the aerating device moves in the direction of the flow guide groove after being guided through the guide plate, so that water passes through the flow guide groove, enters the collecting cylinder in the tangent direction of the collecting cylinder to form rotational flow, and flows back to the pond through the water outlet and the reflux tank. According to a pond industrialized cultivation waste collecting method, along with the rotational flow of the water, waste is centralized to the lower portion of the center of the collecting cylinder gradually, and a water pumping pump pumps the water containing the waste through the water pumping pipe.

Description

technical field [0001] The technology relates to a device and method for collecting waste such as residual bait and feces during pond industrialized cultivation. Background technique [0002] With the advancement of technology, the current conventional fish farming generally has an output of more than 1000 kg per mu, and there are not a few intensive fish ponds with an output of more than 1500 kg per mu. The main means of maintaining such a high yield is the large-scale use of compound feed, a large number of water changes and the use of fishing machinery. Under normal circumstances, the bait coefficient is about 2.5, the water consumption per ton of fish is about 4,000 tons, and the power per mu is about 0.7 kilowatts. Studies have shown that in fish farming, about 70-80% of the fed feed is discharged into the environment in the form of dissolved and particulate matter (the so-called residual bait), which will lead to eutrophication of the water environment inside and outs...

Problems solved by technology

[0003] The American Soybean Association carried out pond industrialization in Suzhou, Jiangsu Province in 2013 and achieved initial success, but it still has defects such as low collection rate and complicated equipment in the collection of residual bait and manure.
