Drainage mechanism of fish culture container

Abstract

The invention discloses a drainage mechanism of a fish culture container. The drainage mechanism comprises a filter box; a cover plate is arranged at the top of the filter box; a plurality of water outlets are formed in the bottom of the filter box; a water inlet pipe is fixedly arranged on the top surface of the cover plate in a penetration manner; the top end of the water inlet pipe is fixedly connected with the water outlet end of a water pump; a filter cylinder is arranged in the filter box; a filter screen is fixedly arranged on the bottom surface of the filter cylinder; the filter cylinder is filled with granular compound fertilizer; an inserting cylinder is vertically and fixedly arranged on the top surface of the filter screen; the inserting cylinder is in inserting fit with the lower end of a rotating shaft; the lower end of the rotating shaft is fixedly connected with a connecting block through a spring; a plurality of stirring blades are fixedly arranged on the surface of the rotating shaft; a swing disc is fixedly arranged at the top end of the rotating shaft; and a plurality of round holes are formed in the edge of the swing disc in a penetration manner. Water in the fish culture container is pumped out through the water pump and conveyed into the filter cylinder, the compound fertilizer in the filter cylinder is used for filtering the water, fish manure, residualfeed, algae and the like are intercepted in the filter cylinder, and new fertilizer rich in fish manure, residual feed and algae is prepared.

Description

technical field [0001] The invention relates to the field of fish farming containers, in particular to a drainage mechanism for a fish farming container. Background technique [0002] The fish farming container is a kind of container used for fish farming. Due to its relatively closed breeding environment, the water in the container tends to accumulate fish feces, residual bait, algae, etc. after long-term use, resulting in turbidity of the water body. Therefore, it is necessary to regularly clean the water in the container When changing the water, the water in the container is often discharged directly, and the fish feces, residual bait and algae in the water cannot be reused, which causes waste and eutrophication of the discharge site. Contents of the invention [0003] The object of the present invention is to provide a fish farming container drainage mechanism to solve the above technical problems. [0004] In order to solve the problems of the technologies described ...
