Description

A shrimp farming system with solids emission

technical field

The utility model relates to a shrimp raising system for discharging solids, belonging to the technical field of factory shrimp raising systems.

Background technique

At present, the discharge technology of solid wastes such as shrimp shells, dead shrimps, and leftovers in the factory shrimp farming system is still relatively backward. Generally, small meshes are used to prevent the escape of live shrimp, but this will result in the vast majority of shrimp shells. Isosolids are difficult to discharge from the aquaculture system, which will cause secondary pollution of the aquaculture system. However, if a larger mesh outlet is used, some live shrimp will escape from the outlet and cause economic losses.

The existing industrial shrimp farming system cannot reasonably discharge solid wastes such as shrimp shells and dead shrimps into the farming system, which will cause secondary pollution to the farming system; or when solid wastes such as dead shrimps are discharged, live shrimps and The solids are discharged together, causing the live shrimp to escape.

In addition, the anti-escape net of the water outlet will also be blocked due to the attachment of microorganisms such as heterotrophic bacteria, which cannot solve the removal function of microorganisms; manual cleaning is required to prevent the water from being blocked.
