Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a circulating purification device for aquaculture water. Background Art

[0002] In aquaculture, the accumulation of feed and feces in the breeding pond affects the survival of fish, so water needs to be changed regularly. When changing the water, the sewage needs to be treated. Direct discharge of untreated sewage will pollute the environment. In addition, the treated water can be reused, which can also reduce costs. In the existing sewage treatment, treatment agents are added to combine harmful substances in the sewage or decompose impurities in the sewage, and stratification is achieved through sedimentation. The stratified water is then exported out of the treatment pool separately. However, when extracting the water in the stratification, the suction of the water pump will suck out some of the impurities after stratification and sedimentation together with the water source, affecting the efficiency of sewage treatment. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned problems and to provide a circulating purification device for aquaculture water.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A circulating purification device for aquaculture water comprises a treatment tank, wherein one end of the top of the treatment tank is connected to a water inlet pipe, and one end of the bottom of the treatment tank is connected to a water outlet pipe. An isolation member for preventing sediment from reflux is provided at the bottom of the treatment tank. The isolation member comprises a plurality of isolation strips evenly arranged on the inner wall of the treatment tank. The isolation strips have a trapezoidal cross-section and are narrow at the top and wide at the bottom. Adjacent isolation strips are separated into a material trough, and the material trough is wide at the top and narrow at the bottom. A dredging member for dredging the material trough is movably provided in the treatment tank.

[0006] As a further description of the above technical solution:

[0007] The clearing piece includes a plurality of clearing plates that move vertically in the material blanking trough, the clearing plates are in the shape of comb teeth, the thickness of the clearing plates is the same as the width of the material blanking trough, a connecting plate is fixedly connected to both ends of the plurality of clearing plates, a connecting frame is connected to the top ends of the two connecting plates, electric push rods are installed on the outer opposite sides of the top of the treatment pool, and the top ends of the telescopic ends of the electric push rods are fixedly connected to the corresponding positions of the connecting frame.

[0008] As a further description of the above technical solution:

[0009] A guide inclined plate is arranged at the bottom of the treatment pool, a flow opening is opened on the outer wall of one side of the treatment pool facing the lower end of the guide inclined plate, and a sealing plate is sealed in the flow opening.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] In the utility model, the isolation piece and the dredging piece are used to isolate the treated and layered sewage, so that the settled impurities will not be stirred up in the clean water source due to the suction of the water pump, and will always remain settled under the isolation piece. The impurities settled from the chute can also be dredged to avoid the impurities being stuck in the chute, making it impossible for subsequent impurities to settle.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Embodiment 1:

[0017] like Figure 1-2As shown, a circulating purification device for aquaculture water comprises a treatment tank 1, wherein one end of the top of the treatment tank 1 is connected to a water inlet pipe 2, and one end of the bottom is connected to a water outlet pipe 3. An isolation member for preventing sediment from surging back is provided at the bottom of the treatment tank 1, and the isolation member comprises a plurality of isolation bars 4 evenly arranged on the inner wall of the treatment tank 1, and the isolation bars 4 are trapezoidal in cross section, narrow at the top and wide at the bottom, and adjacent isolation bars 4 are separated into troughs, and the troughs are wide at the top and narrow at the bottom. When the water pump sucks the treated water source, the pressure increases due to the wide top and narrow bottom of the trough, and impurities are not easily sucked up. A dredging member for dredging the trough is movable in the treatment tank 1. The dredging component includes a plurality of dredging plates 5 which move vertically in the blanking trough. The dredging plates 5 are in the shape of comb teeth. The comb-tooth dredging plates 5 can dredge the blanking trough without being unable to move downward due to pressure, and the upper and lower parts of the blanking trough are always kept connected, and impurities and water can be discharged from the comb-tooth groove. The thickness of the dredging plates 5 is the same as the width of the blanking trough. A connecting plate 6 is fixedly connected at both ends of the plurality of dredging plates 5. A connecting frame 9 is connected to the top ends of the two connecting plates 6. Electric push rods 10 are installed on the outer opposite sides of the top of the treatment pool 1. The top ends of the telescopic ends of the electric push rods 10 are fixedly connected to the corresponding positions of the connecting frame 9. The electric push rods 10 are used to move up and down with the connecting frame 9 and the connecting plate 6 with the dredging plates 5 at the bottom thereof to realize the dredging of the blanking trough. A guide ramp 7 is provided at the bottom of the treatment tank 1, and a flow port is opened on the outer wall of the treatment tank 1 on one side facing the lower end of the guide ramp 7, so as to centrally clean the settled impurities. A sealing plate 8 is sealed in the flow port. The sewage after treatment and stratification is isolated by the cooperation of the isolating piece and the dredging piece, so that the settled impurities will not be stirred in the clean water source due to the suction force of the water pump, and will always remain settled under the isolating piece. The impurities settled from the chute can also be dredged to avoid the impurities being stuck in the chute, making it impossible for subsequent impurities to settle.
