Description

Technical Field

[0001] The utility model relates to the technical field of fishery, in particular to an integrated device for oxygenating inlet and outlet of factory-scale circulating water. Background Art

[0002] Fishery farming, also known as aquaculture, refers to the cultivation of fish and various seafood for human consumption in artificially created onshore fish ponds. It generally encompasses the entire process from seedling to aquatic product under artificial breeding and management. Broadly speaking, it also encompasses the proliferation of aquatic resources. Fishery farming methods include extensive, intensive, and high-density intensive farming. Extensive farming involves releasing seedlings into small or medium-sized natural waters and growing aquatic products entirely on natural feed, such as fish farming in lakes and reservoirs and shellfish farming in shallow waters. Intensive farming involves growing aquatic products in smaller water bodies using feeding and fertilization, such as pond farming, cage farming, and pen farming. High-density intensive farming utilizes methods such as flowing water, temperature control, oxygenation, and feeding high-quality feed to achieve high yields in small water bodies, such as high-density flowing water farming of fish and shrimp.

[0003] However, during the breeding process, the oxygen content of the water in the fish pond is usually insufficient, and it is necessary to use oxygenation equipment to increase the oxygen content of the water. However, the oxygenation effect is general and cannot achieve the expected results. There is room for improvement in the existing technology. Summary of the Invention

[0004] In response to the above-mentioned existing situation, the present utility model provides an integrated device for oxygenating circulating water inlet and outlet in a factory, which is characterized in that it includes a fish pond for breeding, a Roots blower for oxygen supply and a water treatment tank. A water pump for water supply is provided between the water treatment tank and the fish pond. Both ends of the water pump are respectively arranged in the water treatment tank and the fish pond through an inlet pipe and an outlet pipe. An aeration pipe is provided at one end of the inlet pipe, and an aeration gun and a valve are provided on the outlet pipe. A plurality of air inlets for inputting pure oxygen are provided at one end of the aeration pipe facing the inlet pipe, and a connector for installing the aeration pipe is provided at one end of the inlet pipe facing the aeration pipe.

[0005] Preferably, the connecting piece includes a connecting pipe, the outer periphery of which is fixedly provided with a fixing ring, and the fixing ring is fixedly provided with a plurality of spring pieces extending in the direction of the aeration pipe at one end facing the above-mentioned aeration pipe. The plurality of spring pieces are surrounded by the outer periphery of the connecting pipe, and the spring pieces are evenly distributed on the fixing ring. An installation cavity for inserting the aeration pipe is formed between the spring piece and the connecting pipe, and a clamp is formed around the outer periphery of the spring piece for locking the spring piece to deform in the direction of the connecting pipe.

[0006] Preferably, a pressing block for pressing against the aeration pipe is fixedly provided on the side of the spring piece facing the connecting pipe. The pressing block is located on the side of the spring piece away from the fixing ring and is made of silicone.

[0007] Preferably, an inclined surface is provided on one end of the pressing block away from the fixing ring, and the distance between the inclined surface and the outer wall of the connecting pipe gradually increases in the direction away from the fixing ring.

[0008] Preferably, a slot for clamping the clamp is provided on the spring piece.

[0010] Compared with the existing technology, the utility model supplies oxygen to the fish pond through a Roots blower, and connects pure oxygen to the aeration pipe in the treatment pool to mix with the water in the aeration pipe to increase the oxygen concentration in the water. The water with high oxygen content in the aeration pipe reaches the aeration cannon above the fish pond through a water pump. When the water flows through the aeration pipe, the cross-section decreases and the speed increases, forming a negative pressure near the cross-section, sucking air into the aeration pipe, further increasing the oxygen content in the water, and greatly improving the oxygen supply effect.

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0019] like Figure 1-6As shown, a factory-scale circulating water inlet and outlet oxygenation integrated device is characterized in that it includes a fish pond 1 for breeding, a Roots blower 2 for oxygen supply and a water treatment tank 3. A water pump 4 for water supply is provided between the water treatment tank 3 and the fish pond 1. The two ends of the water pump 4 are respectively arranged in the water treatment tank 3 and the fish pond 1 through an inlet pipe 5 and an outlet pipe 6. An aeration pipe 7 is provided at one end of the inlet pipe 5, and an aeration gun 8 and a valve 9 are provided on the outlet pipe 6. The aeration pipe 7 is provided with a plurality of air inlets 10 for inputting pure oxygen at one end facing the inlet pipe 5, and a connector 11 for installing the aeration pipe 7 is provided at one end of the inlet pipe 5 facing the aeration pipe 7. Oxygen is supplied to the fish pond 1 through the Roots blower 2, and pure oxygen is connected to the air inlet 10 of the aeration pipe 7 in the treatment pool and mixed with the water in the aeration pipe 7 to increase the oxygen concentration in the water. The water with high oxygen content in the aeration pipe 7 reaches the aeration cannon 8 above the fish pond 1 through the water pump 4. When the water flows through the aeration pipe 7, the cross-section decreases and the speed increases, forming a negative pressure near the cross-section, sucking air into the aeration pipe 7, further increasing the oxygen content in the water, and greatly improving the oxygen supply effect.

[0020] The connector 11 includes a connecting tube 12, the outer circumference of which is fixedly provided with a retaining ring 13. A plurality of spring clips 14 extending toward the aeration tube 7 are fixedly provided on the retaining ring 13 at one end thereof. The plurality of spring clips 14 surround the outer circumference of the connecting tube 12 and are evenly distributed on the retaining ring 13. A mounting cavity 15 for inserting the aeration tube 7 is formed between the spring clips 14 and the connecting tube 12. A clamp 16 is provided around the outer circumference of the spring clips 14 to lock the spring clips 14 in the direction of the connecting tube 12. A pressure block 17 is fixedly provided on the side of the spring clip 14 facing the connecting tube 12, for pressing against the aeration tube 7. The pressure block 17 is located on the side of the spring clip 14 away from the retaining ring 13 and is made of silicone. The end of the pressure block 17 away from the retaining ring 13 has an inclined surface 18, and the distance between the inclined surface 18 and the outer wall of the connecting tube 12 gradually increases as it moves away from the retaining ring 13. During installation, the aeration tube 7 is inserted into the installation cavity 15, and the clamp 16 is tightened to drive the spring piece 14 to bend toward the connecting tube 12 at one end away from the fixing ring 13, so that the pressing block 17 is pressed against the aeration tube 7 and deformed with the extrusion until the two adjacent pressing blocks 17 contact each other, completely pressing the aeration tube 7 against the connecting tube 12 to complete the connection and fixation of the aeration tube 7. The inclined surface 18 provided on the pressing block 17 allows the spring piece 14 to rotate with the negotiation after being bent and deformed, so that the pressing block 17 is completely attached to the aeration tube 7 and pressed more tightly.

[0021] The spring clip 14 is provided with a slot 19 for engaging the clamp 16. The bottom of the slot 19 is tilted gradually toward the inside of the connecting tube 12, toward the fixing ring 13. After the clamp 16 drives the spring clip 14 to bend and deform, the clamp 16 gradually and completely abuts against the bottom of the slot 19, providing a more stable locking position and preventing the clamp 16 from shifting, making the connection more secure.

[0022] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising from these variations or modifications to the specification remain within the scope of protection of this utility model.
