Environment-friendly fish excrement collection treatment device for aquatic product breeding net cage

Abstract

The invention discloses an environment-friendly fish excrement collection treatment device for an aquatic product breeding net cage. The device comprises a mounting frame, the mounting frame is of a ring structure, and net cage supports are evenly and fixedly buckled at the outer side of the mounting frame and are metal rings; net bags are fixedly arranged at the exteriors of the net cage supportsand are cylindrical nylon net bags, chassis are fixedly arranged at the bottoms of the net bags, and through holes are formed in the middles of the chassis and communicated with water pumping pipes.According to the environment-friendly fish excrement collection treatment device for the aquatic product breeding net cage, by adopting an automatic control mode, fish excrement at the bottom of the net cage is automatically collected and treated, a filter element only needs to be cleaned or replaced manually and periodically, and the problem of eutrophic water is effectively solved; meanwhile, byadditionally arranging an air pump and aerator pipes, the content of oxygen in water is increased, and the device is beneficial to high-density breeding in the net cage.

Description

Technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to an environmentally-friendly aquatic product cultivation net cage fish manure collection and treatment device. Background technique [0002] In the aquatic product cage culture, the principle of “resource conservation and environmental friendliness” is often neglected. The residual bait and fish manure of aquatic products cause oxygen consumption and overload of nitrogen and phosphorus in the water body, leading to eutrophication and pollution of the water body. The virtuous cycle of the aquaculture water ecosystem and the sustainable development of the aquaculture industry. Chinese patent 200920169184.9 discloses an environmentally friendly ecological aquatic product breeding net cage, which can collect fish manure to prevent the loss of residual bait and aquatic product fish manure from causing oxygen consumption and the overload of nitrogen and phosphorus in the water ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a device for collecting and treating fish feces in net cages for environmental protection of aquatic products. It adopts an automatic control method to automatically collect and process the fish feces at the bottom of the net cages, and only manual labor is required. It is enough to clean or replace the filter element regularly to effectively solve the problem of eutrophication in the water body. At the same time, add an air pump and aeration tube to increase the oxygen content in the water, which is beneficial to high-density breeding in the cage, and can effectively solve the problems in the background technology
