5. Improvements to containers (breeding boxes)
8-11, A fish tank with a dirt collecting groove comprises a tank body 101, wherein the tank body can be rectangular or cylindrical, the tank body is provided with a concave tank bottom, the dirt collecting groove 102 is arranged below the tank bottom, and the dirt collecting groove is communicated with an inner cavity of the tank body; a sewage outlet 108 is arranged on the sewage collecting tank; the concave part is bowl-shaped or is formed by butt joint of inclined bottom plates. A water permeable plate 109 is arranged between the sewage collecting tank and the tank bottom. The water permeable plate can prevent fish from entering the sewage collecting tank, and the water permeable plate is preferably a grid plate. But fish manure and feed residues can enter the sump. Each grid has a side length of not less than 1 cm. The depressed part is formed by butt joint of two inclined bottom plates, an included angle between the two inclined bottom plates is an obtuse angle, the box body is a rectangular box body, the sewage collecting groove is a strip-shaped groove, and the sewage collecting groove is arranged along the length direction of the box body. The included angle of the bottom plate relative to the horizontal plane is between 10 and 30 degrees. The inside of the tank is provided with a plurality of flush pipes 104 for flushing the bottom of the tank. For flushing waste into the sump. The flushing pipe is vertically arranged. The flushing pipes are preferably arranged in 2 rows along the longer inner wall of the tank, are arranged on two opposite sides and are arranged at equal intervals, and are flushed at regular intervals, such as for example once for 15 minutes under the control of the controller. The lower end of the flushing pipe is provided with a fin-shaped nozzle 105. This increases the flushing area. The flushing pipe is in butt joint with the circulating water inlet pipe or with an external flushing water source. If the circulating water is used for flushing, no external energy source is needed, the energy-saving effect is achieved, and if a separate external water source is used, a booster pump can be further added, so that the flushing effect is better. The sewage outlet is in butt joint with the circulating water treatment equipment. The box body is supported by the supporting legs. The box body is a container, and a fish outlet 107 is arranged on the box body. The fish raising box with the sewage collecting tank is beneficial to the concentration of waste residues (the excrement and the feed residues of fish) to the sewage collecting tank because the concave part of the box bottom is arranged in the middle. In addition, the water flushing pipe with the nozzle is arranged, the bottom plate is further flushed through external force, the dirt collecting effect is enhanced, waste residues are discharged in time subsequently, and therefore fish can be better generated in the box body.
It will be understood that modifications and variations will be apparent to those skilled in the art from the foregoing description, and it is intended that all such modifications and variations be included within the scope of the following claims.
