Description

Technical Field

[0001] The utility model relates to the technical field of fish tanks, in particular to a fish tank filtering device. Background Art

[0002] At present, fluidized bed filter materials are used more and more in fish tanks.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] The fish tank filter device in this embodiment is mainly used in fish tanks with water outlet from side grilles. It can be directly embedded and connected between the water body of the fish tank and the water body of the filtration system. The fluidized bed filter material can be tumbled without power supply.

[0031] like Figure 1 - Figure 6As shown, the fish tank filtering device includes a box body 1 and a fluidized bed filter material 2. The box body 1 is arranged in the fish tank 6 from top to bottom, and the fluidized bed filter material 2 is arranged in the box body 1. A first water inlet 11 is arranged at the bottom of the box body 1, and a second water inlet 12 is arranged at the upper part of the side wall of the box body 1. A water inlet 61 and a water outlet 62 are arranged on the side wall of the fish tank 6. Water enters the filtering system from the water inlet 61 for filtration and then flows out from the water outlet 62. The back of the box body 1 is spaced from the side wall of the fish tank 6, and the bottom of the box body 1 is spaced from the bottom of the fish tank 6. A connecting port 13 is arranged on the back of the box body 1. During actual use, after the box body 1 is placed in the fish tank 6, the water in the fish tank 6 will enter the box body 1. After the water enters the box body 1 from the first water inlet 11, an upward water flow is formed. The water enters the box body 1 from the second water inlet 12 to form a downward water flow. Through the action of the two water flows, the fluidized bed filter material 2 in the box body 1 can roll, so that the rolling of the fluidized bed filter material 2 can be achieved without additional power supply. The rolling fluidized bed filter material 2 can make the biofilm fully contact with oxygen and organic matter, greatly improve the biofilm attachment and demolding speed of nitrifying bacteria, and greatly enhance the biochemical filtration effect.

[0032] In this embodiment, the box body 1 is made of transparent material, so that the tumbling fluidized bed filter material 2 has a visual dynamic effect, thereby improving the viewing experience.

[0033] like Figure 2 - Figure 4 As shown, partitions 14 are extended backwards at both side edges of the back side of the box body 1 , and the back side of the box body 1 is spaced apart from the side wall of the fish tank 6 by the partitions 14 to avoid blocking the water inlet and outlet of the fish tank 6 .

[0034] In some further embodiments, Figure 5 As shown, the first water inlet 11 is arranged at the bottom of the box body 1 near the side wall where the second water inlet 12 is located, so that the water flow upward through the first water inlet 11 and the water flow downward through the second water inlet 12 are arranged at intervals. This design enables the fluidized bed filter material 2 to rotate clockwise, thereby further improving the ornamental effect.

[0035] In some further embodiments, Figure 6 As shown, in order to achieve water flow regulation of the second water inlet 12, a water flow regulating device 3 is arranged on the second water inlet 12, and the water flow regulating device 3 can adjust the opening size of the second water inlet 12. When the opening of the second water inlet 12 is larger, the water flow is larger, and the water flow pressure is smaller at this time, and the liquid level in the box body 1 is higher. When the opening of the second water inlet 12 is smaller, the water flow is smaller, and the water flow pressure is larger at this time, and the liquid level in the box body 1 is lower. At this time, the water flows through the second water inlet 12 to form a water column and flows into the box body 1, which can achieve the effect of oxygenating the water body.

[0036] It should be noted that the specific structure of the water flow regulating device 3 is not limited in this embodiment, and it only needs to be able to adjust the opening size of the second water inlet 12 .

[0037] When the water level is high, the fluidized bed filter material 2 tends to float on the water surface above the box body 1. To avoid this problem, Figure 4 As shown, an inclined baffle 4 is arranged on the upper part of the box body 1 , and the lower end of the baffle is inclined and located below the water surface, which can not only prevent the fluidized bed filter material 2 from floating, but also play a guiding role for the fluidized bed filter material 2 .

[0038] In some further embodiments, Figure 3 and Figure 4 As shown, a shielding plate 5 is provided on the upper part of the box body 1, and the function of the shielding plate 5 is to shield the top of the box body 1 to prevent debris from entering the box body 1, such as fish food put in by the automatic feeder.

[0039] In some further embodiments, Figure 3 As shown, the front edge of the box body 1 is provided with an arc surface 15, and the arc surface 15 is provided to prevent the fish from being scratched by the box body 1 when swimming.

[0040] at the same time, Figure 3 As shown, a fish baffle 16 is provided on the top of the side wall of the box body 1 opposite to the second water inlet 12 and extends upward, so that fish are prevented from entering the box body 1 when swimming.

[0041] The fish tank filtering device of the utility model has the advantages of simple structure, good filtering effect and high ornamental value, and is conducive to large-scale promotion.

[0042] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
