Abstract

The utility model provides a sewage net box, in which the dead fish with large volume are concentrated and deposited on the filter plate at the bottom of the first sewage collection box, and the volume of residual bait and fish excrement is relatively small. The small fish can seep out of the holes on the filter plate and finally settle at the bottom of the inverted conical sewage collection tank. The dead fish pass through the first sewage outlet on the side wall of the first sewage collection box and are pumped out of the cage through the first sewage pipe. The bait and fish excrement are pumped out of the net cage through the second sewage outlet at the bottom of the inverted conical sewage collection tank through the second sewage pipe, so that the net cage not only realizes the removal of dead fish, residual bait and The excrement of the fish is discharged in a concentrated manner, and the small-volume residual bait and excrement can be separated from the large-volume dead fish to be discharged separately from the cage, saving the work of the staff to separate the discharge from the cage again.

Description

A sewage cage

technical field

The utility model relates to the field of fishery breeding equipment, in particular to a net cage for sewage discharge.

Background technique

Existing aquaculture net cages are all suspended in the water by floating objects. The upper four sides of the net cage are closely connected with the floating objects, and four support rods are stretched out from the four corners to the water, and are tied to the four support rods at the bottom of the case. Form a cube and enclose the mesh to form a culture cage that is permeable on all sides and bottom. The mesh size of the mesh is determined by the size of the aquatic animal seedlings. Therefore, when feeding bait to enclosed aquatic animals, some excess bait and excrement of aquatic animals will settle to the bottom of the water through the mesh at the bottom of the box. The organic substances in the net cage are easy to rot and stink at the bottom of the water, seriously polluting the water quality. If there is any fluctuation, the water quality around the cage will become muddy and smelly, which will affect the normal growth of aquatic animals and their own safety. This is the so-called "self-pollution" "In severe cases, aquatic animal diseases or even death will occur, and it may also cause red tide disasters in offshore regions.

Utility model content

The utility model provides a sewage discharge net cage, which can conveniently discharge dead fish, residual bait and fish excrement in the net cage in a concentrated manner, and at the same time make small-volume residual bait and excrement separate from large-volume waste. The dead fish are separated and discharged separately from the cages.

In order to achieve the above-mentioned technical effect, the technical scheme of the utility model is as follows:

A sewage net cage, comprising a net cage frame and net clothing, a first sewage collection box is arranged at the bottom of the net clothing, a filter plate is located at the bottom of the first sewage collection box, and a first sewage discharge port is provided on the side wall of the first sewage collection box , the first sewage outlet is connected to one end of the first sewage pipe through the first movable joint, and the other end of the first sewage pipe extends upward to the cage frame and is fixed on the cage frame through the first connection mechanism; the filter plate is connected under the The inverted conical sewage collection box has a second sewage discharge port on the top of the cone of the inverted conical sewage collection box. The second sewage discharge port is connected to one end of the second sewage discharge pipe through the second movable joint, and the other end of the second sewage discharge pipe One end extends upwards to the net cage frame and is fixed on the net cage frame by the second connection mechanism; one end of the first sewage discharge pipe fixed on the net cage frame and one end of the second sewage discharge pipe fixed on the net cage frame are used to connect the suction device.

Preferably, the suction device connected to one end of the first sewage discharge pipe fixed on the net cage frame and one end of the second sewage discharge pipe fixed on the net cage frame is a water pump.

Preferably, both the first sewage pipe and the second sewage pipe are PVC pipes.

Preferably, both the first connection mechanism and the second connection mechanism are buckles.

Compared with the prior art, the beneficial effects of the technical solution of the utility model are:

In the cleaning net cage of the utility model, the dead fish with larger volumes are concentrated and collected on the filter plate at the bottom of the first dirt collection box, and the residual bait and fish excrement are smaller in volume and can be removed from the filter plate on the filter plate. Seep out of the holes and finally settle at the bottom of the inverted conical sewage collection tank. The dead fish pass through the first sewage outlet on the side wall of the first sewage collection box and are pumped out of the net cage by the water pump through the first sewage pipe. The residual bait and fish excrement The second sewage outlet at the bottom of the inverted conical sewage collection tank is pumped out of the net cage through the second sewage pipe, so that the net cage not only realizes the concentrated discharge of dead fish, residual bait and fish excrement in the net cage , It can also separate the small-volume residual bait and excrement from the large-volume dead fish and discharge the net cage separately, saving the work of the staff to separate the net cage discharge again.
