Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, and more specifically, to a sewage discharge device for fishery breeding. Background Art

[0002] Fish toilet is a kind of equipment used for fish farming, usually made of metal or plastic. Its main function is to provide a stable, flat and well-drained growth environment to help fish grow and develop. At present, fish toilets are often installed at the bottom of fish ponds. Fish feces and leftover bait in the water settle to the bottom of the pond. The sewage at the bottom is often high-concentration sewage containing fish feces and leftover bait. The use of bottom drainage for drainage and water treatment is prone to blockage and affects the efficiency of water treatment. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art that the bottom drainage is prone to clogging and affects the water treatment efficiency, and to provide a sewage discharge device for fishery breeding, which has surface drainage and bottom drainage functions, effectively filters the excrement and waste of fish, and ensures clean water quality.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0012] Furthermore, the first buckle and the slot are both in two groups, the two groups of the first buckle are symmetrically arranged, the two groups of the slot are symmetrically arranged, and the slot is located between the two groups of the first buckle. During installation, the first buckle and the second buckle are connected while the block and the slot are aligned and positioned, so as to realize the quick assembly and disassembly of the grille and the toilet body.

[0013] Furthermore, a drainage channel with a spiral structure from top to bottom is formed between the water inlet and the first connection port. The drainage channel adopts a spiral structure from high to low, which is conducive to the discharge of fish feces and bait residues following the water flow.

[0014] Furthermore, the axis of the second connection port coincides with the axis of the toilet body, and the second drain pipe is connected to the bottom of the second connection port, the third drain pipe is connected to the top of the second connection port, and the grille is sleeved on the outer periphery of the third drain pipe.

Figure 1 , Figure 2 shown.

[0027] In the field of fish farming, 75%-95% of the water in the fish pond is water in the surface area, and 5%-15% of the water is water in the bottom water area. The above ratio can be the ratio of the vertical height in the fish pond. The water in the surface water area mainly discharges suspended organic waste and can also control the water level of the fish pond; the water in the surface water area is generally in an open discharge state, and is recycled for a long time after being treated by a water treatment device to keep the water clean; the water in the bottom water area mainly treats sewage with fish feces and feed residues deposited at the bottom.

[0028] The water in the face water area and the water in the bottom water area have different pollutant contents. The water in the face water area has a lower pollutant content, so the second drain pipe 400 can be connected to a water treatment device for long-term circulation; the water in the bottom water area has a higher pollutant content, so the first drain pipe 300 can collect the sewage in the bottom water area into a sewage pool for centralized treatment, or it can be connected to a suitable wastewater treatment device for purification. This embodiment sets drainage interfaces for the water in the face area and the water in the bottom area respectively, has face drainage and bottom drainage functions, and cooperates with the water treatment device to effectively filter fish excrement and waste to keep the water clean.

[0029] In order to realize the connection among the toilet body 100, the grille 600 and the connecting flange 200, in this embodiment, a first connecting portion 140 connected to the connecting flange 200 and a second connecting portion 150 connected to the grille 600 are provided at the top of the toilet body 100, and the connecting flange 200 is provided with a through hole 210 through which the grille 600 can pass. The provision of the first connecting portion 140 and the second connecting portion 150 facilitates the connection and disassembly between the connecting flange 200, the grille 600 and the toilet body 100, and the provision of the through hole 210 prevents the connecting flange 200 from hindering the loading and unloading of the grille 600.

[0030] Specifically, the first connection part 140 is provided with a plurality of evenly distributed first connection holes 141, and the connection flange 200 is provided with a plurality of evenly distributed second connection holes, and the first connection hole 141 is connected with the second connection hole by a connection member, and the connection member can be specifically a screw. The connection member passes through the first connection hole 141 and the second connection hole to connect so that the connection flange 200 and the toilet body 100 clamp the bottom structure of the fish pond such as canvas, so as to achieve the fixed installation of the toilet body 100. In this embodiment, the connection between the connection flange 200 and the toilet body 100 is not limited to the connection form of threaded connection. When the fish pond is made of PP material and the connection flange 200 is also a PP structure, in addition to the threaded connection form, the connection form of ultrasonic welding can also be adopted. Among them, the first connection part 140 is provided with an annular groove 142, and the first connection holes 141 are evenly distributed at the bottom of the annular groove 142; the setting of the annular groove 142 can prevent the water flow from backwashing the connection flange 200, and avoid the connection flange 200 from bulging to form a gap and causing water leakage.

[0031] The inner periphery of the second connection part 150 is provided with a plurality of first buckles 151, and the outer periphery of the grille net 600 is provided with a plurality of second buckles 610, and the first buckles 151 are buckled and connected with the second buckles 610. The first buckle 151 is a clamping part or a buckle part. When the first buckle 151 is a clamping part, the second buckle 610 is a buckle part. When the first buckle 151 is a buckle part, the second buckle 610 is a clamping part. The grille net 600 is connected to the toilet body 100 in the form of a buckle connection, which is convenient for assembly and disassembly.

[0032] In addition, in this embodiment, the axis of the second connection port 130 coincides with the axis of the toilet body 100, and the second drain pipe 400 is connected to the bottom of the second connection port 130, the third drain pipe 500 is connected to the top of the second connection port 130, and the grille net 600 is sleeved on the outer periphery of the third drain pipe 500. The third drain pipe 500 is connected to the second drain pipe 400, and the third drain pipe 500 is used to discharge suspended organic waste and also to control the water level of the fish pond. An elbow 700 is connected between the second drain pipe 400 and the second connection port 130, and the axis of the second drain pipe 400 is perpendicular to the axis of the second connection port 130. Through the connection of the elbow 700, the second drain pipe 400 is arranged horizontally, which effectively reduces the volume occupied by the sewage discharge device for fish farming.
