Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a water purification and recycling structure for aquaculture. Background Technology

[0002] Aquaculture is the practice of humans using aquatic waters available for aquaculture (including planting) to raise aquatic economic animals and plants according to the ecological habits of the aquatic organisms and their requirements for aquatic environmental conditions, employing aquaculture technologies and facilities.

[0003] To raise fish, you must first raise good water. Water is the environment on which fish depend for survival. Good water quality can reduce the occurrence of fish diseases and is more conducive to the growth and survival of fish. At present, the most common way to ensure water quality is to change the water. However, changing the water is labor-intensive and can cause fish to die during the process. In addition, it also wastes a lot of water resources. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water purification and circulation structure for aquaculture.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A water purification and circulation structure for aquaculture includes a box body. An inclined filter plate is installed inside the box body. The filter plate is configured as a folded plate. Both the higher and lower ends of the filter plate are attached to the inner wall of the box body. An opening is provided on the side of the box body that is attached to the lower end of the filter plate. A collection box is provided at one end of the box body below the opening. A connecting pipe is connected to the top of the box body on the side of the filter plate that is at its higher end. A water inlet pipe is connected to the bottom of the connecting pipe. A water outlet pipe is connected to the bottom of the side of the box body near the higher end of the filter plate.

[0007] Preferably, the slope of the higher end of the filter plate is greater than the slope of the lower end.

[0008] Preferably, the angle between the higher end of the filter plate and the horizontal direction is not less than 30°, and the angle between the lower end of the filter plate and the vertical direction is not less than 70°.

[0009] Preferably, there is a gap between the lower end of the filter plate and the bottom of the box, and the gap is at least one-fifth of the height of the box.

[0010] Preferably, a telescopic cylinder with a water inlet pipe connected to its bottom is slidably disposed inside the connecting pipe.

[0011] Preferably, both the connecting pipe and the water inlet pipe are provided with threaded blocks at one end, and the same bidirectional screw is threaded on the two threaded blocks. The two threaded blocks are symmetrically arranged on the bidirectional screw, and a turntable is fixed to one end of the bidirectional screw.

[0012] Preferably, a sliding groove is provided on one side of the box body, and a fixing rod that is slidably connected to the sliding groove is fixed at one end of the water inlet pipe.

[0013] Preferably, the outlet end of the outlet pipe and the inlet end of the inlet pipe at the lowest point are on the same horizontal line.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses an inclined filter plate, which allows the filtered impurities to slide down the filter plate with the water flow. This avoids clogging the filter plate and facilitates the collection and treatment of impurities. At the same time, the filter plate with a greater slope at the higher end than at the lower end makes the impurities move faster initially, which helps them quickly move away from the filtration area of ​​the filter plate. It also increases the distance between the lower end of the filter plate and the bottom of the box, so that the bottom of the box forms a water storage tank for storing the filtered water. The water in this water storage tank will not flow out of the box through the opening of the box.

[0016] 2. This utility model increases the distance between the connecting pipe and the inlet pipe by rotating the bidirectional screw through the turntable, thereby changing the horizontal height of the inlet end of the inlet pipe. This can purify floating matter on the surface of the aquaculture pond and purify mud and sand at the bottom of the aquaculture pond, thus improving its practical value. Attached Figure Description

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] like Figure 1 As shown, this utility model discloses a water purification and circulation structure for aquaculture, comprising a housing 1. An inclined filter plate 4 is installed inside the housing 1. The inclined filter plate 4 allows filtered impurities to slide down the water flow along the filter plate 4, preventing clogging and facilitating impurity collection and treatment. Figure 3 As shown, filter plate 4 is configured as a folded plate, with the slope of the higher end of filter plate 4 being greater than that of the lower end. The angle between the higher end of filter plate 4 and the horizontal direction is set to 30°, and the angle between the lower end of filter plate 4 and the vertical direction is set to 70°, ensuring that the slope change is not less than 10°. Both the higher and lower ends of filter plate 4 are in contact with the inner wall of the box 1. There is a gap between the lower end of filter plate 4 and the bottom of the box 1, and the gap is at least one-fifth of the height of the box 1, so that the bottom of the box 1... A water storage tank is formed to store filtered water. The side of the tank body 1 that is in contact with the lower end of the filter plate 4 has an opening, and a collection box 3 is set at one end of the tank body 1 below the opening. The filter plate 4, whose slope at the higher end is greater than that at the lower end, makes the impurities move faster initially, which is beneficial for them to quickly move away from the filtration area of ​​the filter plate 4. On the other hand, it can increase the distance between the lower end of the filter plate 4 and the bottom of the tank body 1. The water in the storage tank will not flow out of the tank body 1 through the opening.

[0026] like Figure 2 As shown, a connecting pipe 2 is connected to one side of the top of the housing 1, at the high end of the filter plate 4. A telescopic cylinder 12 is slidably and sealed at the bottom of the connecting pipe 2. A water inlet pipe 6 is connected to the bottom of the telescopic cylinder 12. Figure 4As shown, threaded blocks 9 are provided at one end of both the connecting pipe 2 and the inlet pipe 6. The same bidirectional screw 10 is threaded on both threaded blocks 9, and the two threaded blocks 9 are symmetrically arranged on the bidirectional screw 10. A turntable 11 is fixed to one end of the bidirectional screw 10. The turntable 11 drives the bidirectional screw 10 to rotate, thereby increasing the distance between the connecting pipe 2 and the inlet pipe 6, thus changing the horizontal height of the inlet end of the inlet pipe 6. This can purify floating matter on the surface of the aquaculture pond and purify mud and sand at the bottom of the aquaculture pond, improving its practical value. A sliding groove 7 is opened on one side of the box body 1, and a fixed rod 8 that is slidably connected to the sliding groove 7 is fixed to one end of the inlet pipe 6 to ensure that the inlet pipe 6 will not rotate when the turntable 11 rotates. The bottom of the side of the box body 1 near the high end of the filter plate 4 is connected to the outlet pipe 5, and the outlet end of the outlet pipe 5 is on the same horizontal line as the inlet end of the lowest inlet pipe 6, ensuring that the raising and lowering of the inlet pipe 6 will not be affected by the outlet pipe 5.

[0027] In use, the horizontal height of the inlet end of the water inlet pipe 6 is adjusted by rotating the turntable 11. The water inlet pipe 6 is placed in the aquaculture pond, and the water pump valves on the connecting pipe 2 and the outlet pipe 5 are turned on. The water in the aquaculture pond enters the box 1 through the water inlet pipe 6, the telescopic cylinder 12 and the connecting pipe 2 and is filtered by the filter plate 4. The filtered water falls into the bottom of the box 1 and is discharged back into the aquaculture pond through the outlet pipe 5. The impurities filtered by the filter plate 4 flow into the collection box 3 along with the water flow for unified collection and treatment.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
