Description

Technical Field

[0001] This utility model relates to the field of fish pond filtration technology, specifically to a high-efficiency fish pond filtration and purification device. Background Technology

[0002] After prolonged use, the water quality in a fishpond will gradually deteriorate. This deterioration can lead to fish diseases and affect their growth. Therefore, it is crucial to regularly purify the water in the fishpond.

[0003] As disclosed in the patent announcement CN211471099U, a high-efficiency fishpond filtration and purification device includes a support mechanism. Four filter boxes with open top surfaces are vertically arranged above the support mechanism. A top plate is located above the upper filter box, and the bottom surface of the top plate is in contact with the top surface of the upper filter box. The beneficial effects of this invention, achieved by using the above technical solution, are that the multiple vertically arranged filter boxes facilitate multiple filtrations of the fishpond water, resulting in better purification of the water in the fishpond.

[0004] Although the aforementioned patent features multiple vertically arranged filter boxes, the curved pipes are positioned close to the inner wall of the filter boxes, causing water to flow downwards along the box walls upon entry. This results in the filter material near the curved pipes being overloaded, while the central filter components remain largely idle due to insufficient water flow. This uneven water flow distribution causes the edge filter material to fail prematurely due to bearing the full load for extended periods, forcing users to frequently replace the entire filter layer. In reality, most of the material in the central section does not perform its intended function, leading to resource waste and increased maintenance costs. Consequently, this seemingly efficient filtration system is significantly less effective in actual operation. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5 As shown, this utility model provides a technical solution:

[0027] A high-efficiency fishpond filtration and purification device includes a base plate 1, with a purification box 2 fixedly connected to its top. A circular chamber 3 is formed in the middle of the purification box 2. A rotating filtration mechanism is installed inside the circular chamber 3. The rotating filtration mechanism includes a motor 7 fixedly connected to the outer side of the middle of the bottom end of the base plate 1, and a rotating disk 8 located at the middle of the top end of the base plate 1. Three circular mounting brackets 9 are concentrically arranged on the upper end of the rotating disk 8, with the diameters of the three circular mounting brackets 9 increasing sequentially from the inside out. Several slots 10 are evenly distributed around the three circular mounting brackets 9, and each slot 10 holds an arc-shaped filter plate 11. The output shaft of the motor 7 passes through the rotating disk 8 and is fixedly connected to a vertical spray pipe 12. The top end of the spray pipe 12 is rotatably connected to the output end of an output pipe 6 via a rotary joint 13. The rotating filtration mechanism also includes a circular cover 14 fixedly connected to the bottom end of the rotating disk 8, and a drive gear 15 fixedly connected to the middle of the output shaft of the motor 7. A bearing is rotatably connected to the left side of the middle of the top end of the base plate 1, meshing with the drive gear 15. The driven gear 16 is fixedly connected to the upper end of the inner wall of the circular cover 14, and a gear ring 17 meshing with the driven gear 16. The water pump 4 is fixedly connected to the upper end of the outer side of the back of the purification box 2. The input end of the water pump 4 is fixedly connected to the input pipe 5, and the output end of the water pump 4 is fixedly connected to the output pipe 6. The output pipe 6 cooperates with the rotary filter mechanism. A cleaning mechanism is provided between the purification box 2 and the rotary filter mechanism. The cleaning mechanism includes brackets 20 symmetrically fixed to both sides of the top of the purification box 2, and a screw threaded to the middle of the brackets 20. Several fixed screws 21 are fixedly connected to the bottom end of the fixed screws 21, and a vertical rotating rod 22 is fixedly connected to the bottom end of the rotating rod 22 through a bearing. The brush roller 23 is rotatably connected to the bottom end of the rotating rod 22. The brush roller 23 rolls in contact with the inner end face of several arc-shaped filter plates 11. A sealing ring 18 is fixedly connected to the lower end face of the circular cover 14. An annular groove 19 that slides and matches the sealing ring 18 is opened at the top of the bottom plate 1. A drain pipe 24 is fixedly connected to the lower front of the purification box 2. One end of the drain pipe 24 extends into the interior of the circular chamber 3.

[0028] In this embodiment, the combined use of the rotating spray nozzle 12 and the counter-rotating disc 8 achieves the dual effects of uniform distribution of rotating water flow and dynamic filtration, solving the problem of uneven load on filter material caused by water flow along the tank wall in the prior art.

[0030] Working principle: Water pump 4 draws water into the fish pond through input pipe 5, and then delivers it to rotary joint 13 through output pipe 6 before entering nozzle 12; motor 7 simultaneously drives two motion systems: its output shaft directly drives nozzle 12 to rotate to form a rotating water flow, and at the same time, through the meshing transmission of drive gear 15, driven gear 16 and gear ring 17, the rotating disk 8 obtains a rotational motion opposite to that of nozzle 12; the three-layer arc-shaped filter plate 11 rotates under the drive of rotating disk 8 to form a dynamic filter surface, and the water flow of rotating nozzle 12 impacts the arc-shaped filter plate 11 rotating in the opposite direction to produce a enhanced filtration effect; brush roller 23 automatically cleans the filter plate, and the filtered clean water returns to the fish pond through drain pipe 24. When it is necessary to clean the dirt accumulated between rotating disk 8 and the bottom of circular mounting bracket 9, multiple arc-shaped filter plates 11 are removed in sequence and the external cleaning pipeline is connected to input pipe 5. The high-pressure water flow sprayed by nozzle 12 forces the dirt accumulated below to be discharged from drain pipe 24.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
