Embodiment

[0012] Example: refer to Figure 1 to Figure 3 , a crab fattening water tank with a sewage discharge structure, comprising a box body 1 with an opening on the upper side, wherein: the front edge of the box body 1 is provided with a flap door 2; the bottom surface of the box body 1 has a sewage outlet 14 that can be connected to a drainage control device; the box body 1. The bottom has raised water guide strips 13 arranged in parallel; the water inlet pipe 3 is provided above the end side of the water guide strips 13 away from the sewage outlet 14. When cleaning, open the sewage outlet 14, the water inlet pipe 3 is opened to the maximum, and the water flow can quickly flow to the sewage outlet 14 along the water guide bar 13, which has a better sewage cleaning effect than the prior art. The edge of the water guide strip 13 has a concave pressurized arc 13a. Compared with the single parallel water guide bar 13, the pressurized arc 13a has obvious cleaning effect. The indented ...

Abstract

The invention discloses a crab fattening sink provided with a blow-down structure. The crab fattening sink comprise a box body provided with an opening formed in the upper side, wherein a flap valve is arranged on the front edge of the box body. The bottom face of the box body is provided with a sewage draining port which can be connected with a water draining control device. Protruded water guide strips arranged in parallel are arranged at the bottom of the box body. A water inlet pipe is arranged above the end sides, away from the sewage draining port, of the water guide strips. During cleaning, the sewage draining port is opened, the water inlet pipe is opened to the greatest extent, water can quickly flow towards the sewage draining port along the water guide strips, and the crab fattening sink has better sewage draining and removing effect compared with the prior art. Therefore, the crab fattening sink has the advantages of facilitating large-scale fattening, being low in management cost and good in flushing effect, being suitable for automatic cleaning, enabling scraps not to easily deposit and having certain cleaning effect on crab body surfaces.

Description

technical field [0001] The invention relates to a large-scale temporary breeding equipment for aquatic products, in particular to a water tank for fattening crabs with a sewage discharge structure. Background technique [0002] The traditional method of obtaining red crabs is generally to catch swimming crabs from the sea, sort them manually, and then sell them in grades. In the normal breeding process, crabs have to shed their shells many times in their lifetime (some people think that the crab stage needs to be Increase the number of shelling). The molting of a crab not only means its development, but also a necessary step for its growth. Crab molting will choose a good environment. They generally choose to do it in relatively quiet, shallow water areas with overgrown aquatic plants and easy concealment. After moulting, the new body that was originally folded in the old shell gradually unfolds, and the body grows accordingly. Usually, the faster the young crabs grow, th...
