Description

Technical Field

[0001] The utility model relates to the technical field of fish pond filtration, and particularly relates to a rotary drum fish pond filtration device. Background Technique

[0002] Raising ornamental fish in the courtyard has become a way of life for many successful people to relieve stress and cultivate sentiment. Raising fish can indeed bring spiritual pleasure, but while enjoying the fun, it will also increase troubles: the fish pond water is turbid, green, smelly, with algae blooming or even dead fish. At present, the pond water is often filtered and purified by a rotary drum filtration device.

[0003] In the rotary drum filtration devices on the market, devices such as drum screens and nozzles are often equipped. However, this method can only simply filter the water quality. In addition, biochemical culture media are added to the rotary drum filtration device. Although the filtration effect can be further improved, the holes in the filter media are relatively large, and some fine impurities cannot be effectively filtered. The filtration method is still monotonous and the filtration effect is limited. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rotary drum fish pond filtration device to solve the above problems, as described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rotary drum fish pond filtration device provided by the utility model includes two boxes. Removable covers are installed at the upper openings of the two boxes. Docking pipes are fixedly installed on the opposite surfaces of the two boxes, and the two docking pipes are detachably connected through connecting flanges. A number of horizontal diversion pipes are arranged inside one of the boxes, and the end parts of the diversion pipes far away from the docking pipes all extend outside the box. A number of leakage holes are formed on the surfaces of the diversion pipes. Below the diversion pipes, there are aeration pipes, and a number of the aeration pipes are installed on the bottom surface of the box. A number of air holes are formed on the upper side of the aeration pipes;

[0007] Inside the other box, there is a water distribution pipe that is connected to the docking pipe and can be flipped. An outlet pipe is communicated with the side wall of the box far away from the docking pipe. A number of inverted L-shaped pipes are communicated on both sides of the water distribution pipe. A supporting structure for fixing the water distribution pipe to a horizontal state is arranged in the middle of the box. A filter screen sleeve is arranged at the lower end of the vertical part of each inverted L-shaped pipe. A number of snap rings adapted to the diameter of the filter screen sleeve are fixedly connected to the inner bottom of the box. A non-woven fabric filter layer is arranged in each filter screen sleeve.

[0008] Adopt the above-mentioned drum fish pond filtering equipment. By connecting two diversion pipes with the drum filtering equipment, then connecting another box body with the docking pipe on this box body, and then connecting several aeration pipes with an aeration pump, filter materials such as cotton bio-balls and biochemical felts are laid on the surfaces of several aeration pipes. When the rough-filtered liquid in the drum filtering equipment enters several diversion pipes, it falls from several leakage holes onto the surface of the filter materials and accumulates. Through the oxygen supply and aeration of the aeration pipes, secondary filtration is completed and it enters another box body through the docking pipe. At this time, through the diversion of the water distribution pipe and several inverted L-shaped pipes, it enters the inside of the filter mesh sleeve and contacts the non-woven fabric filter layer. The non-woven fabric filter layer fully intercepts fine impurities, completing three times of filtration, and finally flows out from the liquid outlet pipe and returns to the fish pond;

[0009] When the non-woven fabric filter layer needs to be replaced, turn the water distribution pipe and the inverted L-shaped pipes upwards. At this time, drive the filter mesh sleeve to be taken out from the snap ring, and then pull out the filter mesh sleeve to replace the non-woven fabric filter layer.

[0010] Preferably, hanging rings are provided above the interiors of both of the box bodies, and fitting rings that are snap-fitted with the hanging rings are fixedly connected to the bottom surfaces of the box covers.

[0011] Preferably, the aeration pipes are designed in a "day" shape. An oxygen-increasing pipe is connected to the upper sides of several aeration pipes, and the input end of the oxygen-increasing pipe extends to the outside of the box body.

[0012] Preferably, a rubber pad is fixedly connected to each air hole, and a slit hole is penetrated through each rubber pad.

[0013] Preferably, the end of the water distribution pipe and the docking pipe are connected through a hose. Several liquid leakage grooves are penetrated through the lower parts of the side walls of the vertical parts of several inverted L-shaped pipes, and the length of the liquid leakage groove is adapted to the height of the filter mesh sleeve.

[0014] Preferably, the supporting structure includes a cross beam. An arc-shaped plate adapted to the water distribution pipe is fixedly connected to the middle of the cross beam, and clamping structures for fixing the water distribution pipe are provided on both sides of the inner wall of the arc-shaped plate.

[0015] Preferably, the clamping structure includes a clamping bar fixedly connected to the inner wall of the arc-shaped plate, and a clamping groove for clamping the clamping bar is opened on the side wall of the water distribution pipe.

[0016] Preferably, outlet pipes are connected to the bottoms of both side walls of both of the box bodies, and valves are installed on the outlet pipes. Grooves adapted to their lengths are opened in the middle of the inner bottoms of both of the box bodies, and the two outlet pipes are respectively located at both ends of the grooves.

[0017] The beneficial effects are as follows:

[0018] 1. By laying filter materials such as cotton bio-balls and biochemical felts on the surfaces of several aeration pipes, when the rough-filtered liquid in the drum filtration equipment enters several diversion pipes, it falls from several leakage holes onto the surfaces of the filter materials and accumulates. After the oxygen supply and aeration by the aeration pipes, secondary filtration is completed and it enters another box through the docking pipe. At this time, through the diversion of the water distribution pipe and several inverted L-shaped pipes, it enters the inside of the filter mesh sleeve and contacts the non-woven fabric filter layer. The fine impurities are fully intercepted by the non-woven fabric filter layer, and tertiary filtration is completed, improving the filtration accuracy and at the same time enhancing the filtration effect.

[0019] 2. Through the design of the hose, the water distribution pipe can be flipped. At this time, the filter mesh sleeve is taken out from the snap ring, and then the filter mesh sleeve is pulled out to replace the non-woven fabric filter layer, which is convenient for replacing the non-woven fabric filter layer.

[0028] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope protected by the present utility model.

[0029] Referring to Figures 1 - 5 As shown in the figure, the present utility model provides a drum fish pond filtering device, which includes two boxes 1. Removable covers 2 are installed at the upper openings of the two boxes 1. Docking pipes 5 are fixedly installed on the opposite surfaces of the two boxes 1, and the two docking pipes 5 are detachably connected through connecting flanges. A number of horizontal diversion pipes 3 are provided inside one of the boxes 1, and the end portions of the number of diversion pipes 3 away from the docking pipe 5 all extend outside the box 1. A number of leakage holes are formed on the surfaces of the number of diversion pipes 3. Aeration pipes 4 are provided below the number of diversion pipes 3. The number of the aeration pipes 4 are all installed on the bottom surface of the box 1, and a number of air holes 13 are formed on the upper side of the aeration pipes 4;

[0030] Inside the other box 1, there is a water distribution pipe 6 that is communicated with the docking pipe 5 and can be flipped. An outlet pipe 10 is communicated with the side wall of the box 1 away from the docking pipe 5. A number of inverted L-shaped pipes 7 are communicated on both sides of the water distribution pipe 6. A supporting structure for fixing the water distribution pipe 6 to a horizontal state is provided in the middle of the box 1. A filter cloth sleeve 8 is provided at the lower end of the vertical portion of each inverted L-shaped pipe 7. A number of snap rings 19 adapted to the diameter of the filter cloth sleeve 8 are fixedly connected to the inner bottom of the box 1. A non-woven fabric filter layer 9 is provided in each filter cloth sleeve 8. The snap ring 19 can limit the filter cloth sleeve 8 located on the bottom surface of the box 1 to prevent dislocation and deviation.

[0031] Referring to Figure 2 As shown in the figure, hanging rings are provided above the interiors of the two boxes 1, and fitting rings 17 that are snap-fitted with the hanging rings are fixedly connected to the bottom surfaces of the covers 2, so that the covers 2 can be stably buckled on the upper ends of the boxes 1.

[0032] As an optional implementation manner, the aeration pipe 4 is designed in a "day" shape. An oxygen-increasing pipe 16 is communicated with the upper side of the number of aeration pipes 4, and the input end of the oxygen-increasing pipe 16 extends outside the box 1. An external oxygen-increasing pump can be communicated with the oxygen-increasing pipe 16 to fill oxygen into the aeration pipe 4, improve the flow rate, and have a good bacteria cultivation effect.

[0033] Referring to Figure 3As shown, a rubber pad 14 is fixedly connected to each air hole 13, and a slit hole 15 is penetrated through each rubber pad 14, so that under normal conditions, the slit hole 15 is in a closed state due to the elastic effect of the rubber pad 14, thereby preventing external liquid from entering the aeration tube 4. When aeration is performed, the gas supports the slit hole 15 to split, allowing the gas to be discharged smoothly.

[0034] Reference Figure 5 As shown, the end of the water distribution pipe 6 is connected to the docking pipe 5 through a hose 18, and a plurality of leakage grooves 21 are penetrated through the lower part of the side wall of the vertical part of the plurality of inverted L-shaped tubes 7. The length of the leakage grooves 21 is adapted to the height of the filter sleeve 8, so that the pool water can leak out from the plurality of leakage grooves 21, thereby increasing the contact range between the water and the non-woven filter layer 9 and improving the filtering effect. The design of the hose 18 allows the water distribution pipe 6 to be turned over, so as to facilitate the replacement of the non-woven filter layer 9.

[0035] As an optional embodiment, the supporting structure includes a crossbeam 20, and an arc-shaped plate 22 adapted to the water distribution pipe 6 is fixedly connected to the middle part of the crossbeam 20. Both sides of the inner wall of the arc-shaped plate 22 are provided with a clamping structure for fixing the water distribution pipe 6. The clamping structure includes a clamping strip 23 fixedly connected to the inner wall of the arc-shaped plate 22, and a clamping groove 24 clamped with the clamping strip 23 is opened on the side wall of the water distribution pipe 6. By placing the water distribution pipe 6 horizontally on the arc-shaped plate 22, the clamping strip 23 is clamped into the clamping groove 24, thereby completing the clamping and fixing of the water distribution pipe 6 in a horizontal state.

[0036] Furthermore, the bottoms of both side walls of the two boxes 1 are connected with outlet pipes 11, and valves are installed on the outlet pipes 11. The middle parts of the inner bottoms of the two boxes 1 are provided with grooves 12 that match their lengths, and the two outlet pipes 11 are respectively located at the two ends of the grooves 12. The grooves 12 can collect the stored water inside the boxes 1. At the same time, by opening the valve on the outlet pipe 11, the stored water can be discharged from the outlet pipe 11.

[0037] The above structure is adopted, by connecting two guide pipes 3 with the drum filter equipment, and then connecting another box body 1 with the butt joint pipe 5 on the box body 1, and then connecting a plurality of aeration pipes 4 with the oxygenation pump, and laying filter materials such as cotton bio-balls and biochemical felt on the surface of a plurality of aeration pipes 4. When the coarse filtered liquid in the drum filter equipment enters the plurality of guide pipes 3, it falls on the surface of the filter material from a plurality of leak holes and accumulates, and is aerated by oxygen supply through the aeration pipe 4, completing secondary filtration and entering another box body 1 through the butt joint pipe 5. At this time, it passes through the diversion pipe 6 and a plurality of inverted L-shaped pipes 7, enters the inside of the filter sleeve 8 and contacts with the non-woven filter layer 9, and the fine impurities are fully intercepted by the non-woven filter layer 9, completing the third filtration, and finally flows out from the liquid outlet pipe 10 to return to the fish pond;

[0038] When it is necessary to replace the non-woven fabric filter layer 9, turn the water distribution pipe 6 and the inverted L-shaped pipe 7 upward. At this time, drive the filter screen sleeve 8 to be taken out from the snap ring 19, and then pull out the filter screen sleeve 8 to replace the non-woven fabric filter layer 9.

[0039] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the said claims.
