Abstract

The invention relates to a blowdown device for aquaculture. The blowdown device comprises a device body, wherein the device body is composed of a cylinder and a cone-shaped body arranged below the cylinder; the cylinder and the cone-shaped body are integrally arranged; a cavity is formed in the cylinder and the cone-shaped body; a plurality of water outlet through holes are formed in the side wall of the cylinder; an upright post is arranged below the cone-shaped body; the lower end of the upright post is in a shape of a needle tip; a plurality of barbs are formed on the side wall of the upright post; openings of the barbs are upward, and a filter screen is arranged in the device body. The blowdown device has the advantage of simple structure; when the blowdown device is used, only the upright post end is inserted into sludge, and then a blowdown pipe is inserted into the cavity, so that blowdown is realized; thus, the blowdown device is difficult to loosen when in use, and a handle is arranged, so that the blowdown device is convenient to lift after being used; in addition, a connecting joint is arranged, so that the blowdown device can be mutually butted with the blowdown pipe preferably.

Description

technical field [0001] The invention relates to the field of aquatic facilities, in particular to a sewage discharge device for aquaculture. Background technique [0002] In the process of indoor aquaculture, the feces produced by aquatic animals, the remaining bait during feeding and other substances produced in the water are very polluting to the water quality. And existing a kind of cultivation pool central blowdown device, comprise trapezoidal PVC pipe cap and PVC cylindrical blowdown pipe, PVC pipe cap internal diameter is an end opening of 160mm, high 50cm, one end of the PVC cylindrical blowdown pipe of diameter 160mm inserts PVC pipe cap The open end of the PVC pipe cap is 50mm in diameter, and one end is closed. The sewage discharger with this structure is easy to loosen during use, so that the sewage discharge effect cannot be achieved. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a sewage di...
