[0002] In order to ensure the growth environment of aquatic organisms in the fish tank, a circulating filtration device is generally set for the fish tank water. Among them, the filter barrel has been more widely used because of its easy assembly and wider applicability of water bodies.

[0003] The filter element of the filter barrel in the prior art has various forms, but there are disadvantages to varying degrees. For example, Chinese Patent Application No. 2022200828996 discloses a filter barrel for fish tanks. The device can meet the basic filtering needs, but its disadvantages are also obvious. That is, when the device is in use, the barrel is filled with water. Due to the high water pressure in the lower sedimentation bin, the solid particles in the water body are easy to flow back upward from the opening of the conical sedimentation bin with the water flow. In this case, the filtering pressure will be increased for the filter screen, and it is easy to cause the filter screen to be blocked. Based on the above disadvantages, the filter screen in the facility has a large mesh density and a high maintenance frequency. In addition, the filter barrels in the prior art are all in an integrated setting, which makes it inconvenient to disassemble and clean them, and the filtering effect is not good.

[0006] The water pipe is used to access the water flow to be filtered;

[0007] A filter material bin bottom plate is provided at the lower part of the water pipe, and a plurality of water holes are provided on the filter material bin bottom plate;

[0008] An inner filter screen cylinder is arranged at the lower part of the water pipe;

[0009] A sedimentation bin partition is provided below the filter bin bottom plate, and the space formed between the filter bin bottom plate and the sedimentation bin partition is the water and sewage diversion area; an outer sedimentation pipe hole is provided on the sedimentation bin partition at a position corresponding to the inner filter screen cylinder; an outer sedimentation pipe is provided extending downward from the edge of the outer sedimentation pipe hole; the inner filter screen cylinder extends downward from the water pipe assembly hole of the filter bin bottom plate through the outer sedimentation pipe, and forms a water gap with the inner wall surface of the outer sedimentation pipe;

[0010] An outer filter screen cylinder is arranged outside the inner filter screen cylinder at intervals; the outer filter screen cylinder is arranged between the bottom plate of the filter material bin and the partition plate of the sedimentation bin, and its lower edge is closely fitted with the outer edge of the outer sedimentation pipe hole.

[0011] The effect achieved thereby is that the component of the utility model is assembled in the filter barrel, with the filter material bin bottom plate and the sedimentation bin partition as intervals, and a water and sewage diversion area, a sedimentation bin and a filter material bin are formed in the filter barrel through structural combination.

[0012] The beneficial effect of the component of the utility model is that the filter barrel formed by installing the filter component in the barrel body has a more reasonable configuration of the internal sedimentation and filtration components compared to the filter barrels in the prior art, and all the components can be flexibly combined and disassembled with the barrel body, which is convenient for maintenance and cleaning. In this component, the water and sewage diversion area, the sedimentation bin and the filter material bin are formed by setting the bottom plate of the filter material bin and the partition of the sedimentation bin.

[0033] The filter barrel 5 comprises a barrel body and a sealing cover, and the barrel body and the sealing cover are buckled;

[0034] The cover is provided with a water inlet pipe port 2 and a water outlet pipe port 3, and a sewage discharge pipe port 8 is also provided on the side of the lower part of the barrel body.

[0035] Embodiment 2:

[0036] The sedimentation filtering component is movably arranged in the filtering barrel 5, and its specific structure adopts the following form:

[0037] Support ribs 9 are provided between the filter bin bottom plate 6 and the sedimentation bin partition 7 of the sedimentation filter component and on the bottom surface of the sedimentation bin partition 7. A sealing ring 19 is provided at the outer edge of the sedimentation bin partition 7 to fit tightly inside the barrel body.

[0039] Embodiment 3:

[0040] The sealing cover of the filter barrel is also provided with a backwashing nozzle 1 and an exhaust valve.

[0041] The effect achieved in this way is that the backwashing pipe port 1 is connected to the external water flow, and the filter material bin, the water and sewage diversion area, and the sedimentation bin are backwashed downward in sequence, and the sewage and solid particles in the filter barrel 5 are discharged through the sewage discharge pipe port 8. During backwashing, the air valve is opened to eliminate the pressure difference between the inside and outside of the barrel, ensuring smooth sewage discharge when the sewage discharge pipe port 8 is opened. Backwashing can reduce the content of toxic and harmful substances such as ammonia nitrogen and nitrite in the water body, reduce the bearing pressure of the filter material for nitrification reaction, and reduce the frequency of manual cleaning of the filter material.

[0042] Embodiment 4:

[0043] In the filter barrel 5, a filter material bin top plate 16 is arranged on the upper part of the water pipe 4, and a plurality of water holes are arranged in an array on the filter material bin top plate 16;

[0045] A water-permeable interlayer is formed between the sealing cover and the filter material bin top plate 16 .

[0046] Preferably, ultrafine filter cotton is arranged in the water-passing interlayer.

[0047] The effect achieved by this is that the water flowing upward after nitrification and filtration of the filter material in the filter material bin flows evenly upward through the water holes on the filter material bin top plate 16 into the water interlayer, and then passes through the ultra-fine filter cotton arranged in the water interlayer and is discharged from the water outlet port 3. When the filter barrel 5 needs to be backwashed, the external water flow is connected from the backwashing port 1. After the backwashing water flows into the water interlayer, it flows evenly downward through the water holes on the filter material bin top plate 16 into the filter material bin, and the backwashing water flows evenly downwardly wash the filter material in the filter material bin.

[0048] The ultra-fine filter cotton finely filters the water flow in the water-passing interlayer, so that the content of powdery fine particles is reduced to the maximum extent when the finely filtered water flow is discharged from the water outlet 3.

[0049] Embodiment 5:

[0050] In the filter barrel 5, a filter material bin bottom plate 6 is arranged below the water pipe 4, and a plurality of water holes are arranged in an array on the filter material bin bottom plate 6;

[0051] Preferably, an assembly hole is provided in the area of ​​the filter material bin bottom plate 6 surrounded by the outer filter screen cylinder 11, which is tightly fitted with the lower part of the water pipe 4, and the water holes on the filter material bin bottom plate 6 are in the form of dense array of small holes.

[0052] Preferably, the filter cotton pad layer 17 is arranged in the filter material bin on the upper part of the filter material bin bottom plate 6 .

[0053] The effect achieved in this way is that the water flow in the filter barrel 5 through the water and sewage diversion area overflows evenly upward through the water holes on the filter material bin bottom plate 6 to enter the filter material bin, continues to overflow evenly upward through the filter cotton pad 17 provided in the filter material bin and evenly distributes the flow between the gaps of the filter material in the bin, so that the nitrifying bacteria film attached to the surface of the filter material is fully exchanged with the flowing water to complete more nitrification reactions to decompose ammonia nitrogen.

[0054] The filter cotton pad layer 17 firstly adheres and intercepts the powdery fine particles in the water flow that overflows upward into the filter material bin.

[0055] Embodiment 6:

[0056] The upper part of the water pipe 4 is connected to the filter material bin top plate 16 by plugging, screwing or fixing;

[0057] The lower part of the water pipe 4 is connected to the bottom plate 6 of the filter material bin by plugging, screwing or fixing.

[0058] The effect achieved by this is that the upper part of the water pipe 4 is tightly connected to the top plate 16 of the filter material bin, and a closed channel is formed between the water inlet pipe 2 to prevent the water to be filtered from escaping and being discharged from the water interlayer through the water outlet pipe 3 before entering the water pipe 4, and at the same time, it is convenient to take and put the filter material. The lower part of the water pipe 4 is tightly connected to the bottom plate 6 of the filter material bin to prevent the water to be filtered from directly escaping from the lower part of the water pipe 4 into the filter material bin and causing pollution to the filter material.

[0059] Embodiment 7:

[0060] Refer to the attached drawings in the specification Figure 3 The inner filter screen cylinder 10 is arranged at the lower part of the filter material bin bottom plate 6 and is connected to the water pipe 4;

[0061] A water gap 12 is formed between the inner filter screen cylinder 10 and the outer sedimentation tube 13;

[0062] Preferably, the inner filter screen cylinder 10 extends downward from the water pipe assembly hole of the filter material bin bottom plate 6 to pass through the outer sedimentation pipe 13, and forms a water gap 12 between the inner wall surface of the outer sedimentation pipe 13;

[0063] Preferably, the portion of the inner filter screen cylinder 10 arranged on the upper part of the outer sedimentation tube 13 is in the form of a water filter screen, and the lower portion passing through the outer sedimentation tube 13 is in the form of a closed water supply pipe body, and the lower water supply pipe body is the inner sedimentation tube 15, and the inner sedimentation tube 15 is surrounded by the outer sedimentation tube 13, and a water gap 12 is formed between the inner sedimentation tube 15 and the outer sedimentation tube 13.

[0064] Embodiment 8:

[0065] The outer settling pipe 13 is in the form of a funnel with the closing end facing downwards, and an outer settling pipe hollow section 14 is provided downwardly extending from the closing end position at the bottom thereof, and a plurality of water holes are arranged in an array on the outer settling pipe hollow section 14 .

[0066] A water gap 12 is formed between the outer settling tube hollow section 14 and the inner filter screen cylinder 10;

[0067] Preferably, the outer settling tube hollow section 14 surrounds the inner filter screen cylinder 10 and forms a water gap 12 between the outer settling tube and the inner filter screen cylinder 10;

[0068] Preferably, a water gap 12 is formed between the outer settling tube hollow section 14 and the inner settling tube 15;

[0069] Preferably, the outer settling pipe hollow section 14 surrounds the inner settling pipe 15, and a water gap 12 is formed between the outer settling pipe 15 and the inner settling pipe 15;

[0070] The effect achieved by this is that, when in use, water is poured into the sedimentation bin, and a sedimentation bin air barrier 18 is formed between the sedimentation bin partition 7, the outer sedimentation pipe 13, the filter barrel 5 and the water in the sedimentation bin; the liquid level in the sedimentation bin is limited by the water-passing holes on the hollow section 14 of the outer sedimentation pipe, and the hollow section 14 of the outer sedimentation pipe is completely located below the liquid level in the sedimentation bin;

[0071] In this case, the water to be filtered flows downward from the water pipe 4, flows through the inner filter screen cylinder 10 to achieve a first interception, and the solid particles intercepted by the inner filter screen cylinder 10 continue to sink, and are restrained by the inner sedimentation pipe 15 set at the lower part of the inner filter screen cylinder 10 to accelerate the sinking into the sedimentation bin and quickly fall to the bottom of the barrel. At the same time, a small amount of water carries the powdery fine particles into the sedimentation bin through the inner sedimentation pipe. The water carrying the powdery fine particles moves slowly in the sedimentation bin and slowly overflows upward from the outer sedimentation pipe 13.

[0072] In the above implementation process, the outer filter screen cylinder 11 intercepts the solid particles escaping from the inner filter screen cylinder 10 for a second time. The solid particles intercepted by the outer filter screen cylinder 11 for a second time sink by gravity and meet the water flow carrying powdery fine particles in the sedimentation bin overflowing upward at the water gap 12. The water flow overflowing upward at the water gap 12 is small and the overflow is slow. The solid particles intercepted by the outer filter screen cylinder 11 for a second time continue to slowly sink into the sedimentation bin at the water gap 12 and fall to the bottom of the barrel. At the same time, the water flow carrying powdery fine particles continues to slowly overflow upward at the water gap 12 and merges with the water flow in the sewage diversion area.

[0073] The function of the water-passing holes on the hollow section 14 of the outer settling pipe is to reduce the sinking resistance of solid particles passing through the inner settling pipe 15 and the water gap 12 when entering the sedimentation bin, and when solid particles float up in the sedimentation bin, they are intercepted by the hollow section 14 of the outer settling pipe, blocking the overflow path of suspended matter in the sedimentation bin and will not participate in the water flow filtration cycle again;

[0074] The air barrier 18 of the sedimentation bin suppresses the fluctuation amplitude of the water body in the sedimentation bin, stabilizes the sedimentation state of the solid particles in the sedimentation bin, and reduces the occurrence of water flow disturbance on the settled solid particles in the sedimentation bin.

[0075] Embodiment 9:

[0076] The water inlet pipe port 2 and the water outlet pipe port 3, the sewage discharge pipe port 8 and the backwash pipe port 1 are respectively provided with control valves, and the exhaust valve is provided with an air blocking component.

[0077] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
