Device for collecting and processing fish excrement in environmentally friendly aquaculture net lift car

Abstract

The invention discloses a device for collecting and processing fish excrement in an environmentally friendly aquaculture net lift car. The device comprises a hollowed-out culturing box, a first motor,a collection box and a second motor, a collection cylinder is welded at the bottom end of the hollowed-out culturing box, a collection cylinder connector is installed at the bottom end of the collection cylinder, a delivery pipe connector is sleeved on the outer surface of the collection cylinder connector, the delivery pipe connector and the collection cylinder connector are mutually clamped andfixed through clamping teeth, the delivery pipe connector is connected with a delivery pipe, the other end of the delivery pipe is connected with a first water pump input port, the first water pump input port is installed on one side of the first water pump, the collection box is installed on one side of the first water pump, a stop block is installed on the interior surface of the collection box, a filter groove is clamped on the stop block, active carbon is arranged at the bottom end of the filter groove, and a filter screen is arranged at the bottom end of the active carbon. A floatation cylinder is adopted to float a hollowed-out culturing net to limit culturing, and a draw-out filter mode is used for removing redundant fish excrement in a water body.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to an environment-friendly aquatic product cultivation net cage fish excrement collection and treatment device. Background technique [0002] In cage culture of aquatic products, the principle of "resource conservation and good environment" is often ignored, so that the loss of residual bait and fish manure of aquatic products will cause oxygen consumption and overload of nitrogen and phosphorus elements in the water body, resulting in eutrophication and pollution of the water body , affect the virtuous cycle of the aquaculture water ecosystem and the sustainable development of the aquaculture industry. Chinese patent 200920169184.9 discloses an environmentally friendly and ecological aquatic product breeding net cage, which can collect fish feces to prevent the loss of residual bait and aquatic product fish feces caused by oxygen consumption and The nitrogen and...
