DETAILED DESCRIPTION

[0022] The following is a more detailed description of the implementation of the utility model in conjunction with the drawings and the figure marks, so that those skilled in the art can implement it after reading this specification. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model. Example

[0023] The utility model provides Figure 1-5 The device for filtering impurities in a fish tank includes a primary filtering unit and a secondary filtering unit to filter out most of the pollutants in the water of the fish tank.

[0024] The primary filtration unit includes a buffer cylinder 10 and a filter cylinder 20 inserted into the buffer cylinder 10. A water inlet is provided at the top of the filter cylinder 20, and a wire filter can be used for the cylinder wall. A drain valve 11 is provided at the bottom of the buffer cylinder 10. The secondary filtration unit includes a guide cylinder 30 provided outside the buffer cylinder 10, and a filter material layer 40 provided between the guide cylinder 30 and the buffer cylinder 10. The guide cylinder 30 is open at the top, and the height of the buffer cylinder 10 is lower than the filter cylinder 20 and the guide cylinder 30 so that the buffer cylinder 10 is connected with the guide cylinder 30. The water in the filter cylinder 20 can flow to the guide cylinder 30 by itself, and a water outlet is provided at the bottom of the guide cylinder 30. In other embodiments, the buffer cylinder 10 can be provided with a notch so that the buffer cylinder 10 is connected with the guide cylinder 30.

[0025] The primary filter unit is mainly used to filter out large particles of pollutants in the fish tank water, mainly fish feces; the filtered water from the primary filter unit enters the secondary filter unit to further filter out small particles of pollutants, and finally the water is discharged from the bottom of the guide tube 30. The water flow direction is as follows Figure 1 Indicated by the arrow.

[0026] Specifically, during filtration, the drain valve 11 is closed, and water containing pollutants enters the filter cartridge 20 from the water inlet, and then flows out from the portion of the filter cartridge 20 that is not covered by the buffer cartridge 10 to the guide cartridge 30. Large particle pollutants are trapped by the filter screen in the filter cartridge 20 and the buffer cartridge 10, and the bottom of the filter cartridge 20 is connected to the buffer cartridge 10. Large particle pollutants are deposited at the bottom of the buffer cartridge 10. When the sediment in the buffer cartridge 10 reaches a preset height, the drain valve 11 is opened to discharge it. After the water entering the guide cartridge 30 passes through at least one filter material layer to filter out small particle pollutants, it is discharged from the bottom of the guide cartridge 30. Compared with the prior art, the utility model filters out large particle pollutants through the filter screen before the water enters the filter material layer, which greatly reduces the number of pollutants entering the filter material layer, reduces the frequency of replacing the filter material layer, and the discharge method of large particle pollutants is simple, convenient, and easy to operate.

[0027] The buffer cylinder 10 is used to retain a certain amount of water, and plays a buffering role on the water falling from the water inlet, reducing the number of large particles of pollutants that are impacted by the water flow into small particles of pollutants. The buffer cylinder 10 cooperates with the filter cylinder 20 to prevent large particles of pollutants from flowing out of the gap between the two with the water flow.

[0028] The secondary filtration unit also includes an annular card plate 50 arranged in the guide tube 30 for supporting the filter material layer 40. A plurality of annular card plates 50 are arranged in sequence from high to low, and the annular card plate 50 is provided with a water outlet 52. Further, the side wall of the guide tube 30 is provided with a plurality of leg groups in sequence and equidistantly along the height direction, and the leg group includes a plurality of legs 31 arranged on the inner wall of the guide tube 30 along the circumferential direction of the guide tube 30; the edge of the annular card plate 50 is provided with a avoidance groove 51 corresponding to the legs, so that the annular card plate 50 and the guide tube 30 can be detachably connected, and the user can arrange the annular card plate according to the number of filter material layers 40. When the annular card plate 50 is installed, the avoidance groove 51 is aligned with the legs 31 and inserted into the guide tube 30. After descending to a certain height, the annular card plate 50 is rotated to stagger the avoidance groove 51 with the legs 31, and the legs 31 can support the annular card plate 50, and then the filter material layer 40 is placed on the annular card plate 50. The filter material layer 40 may be an annular filter cotton. Example

[0029] The utility model provides a fish tank. Figure 1 , 2 The fish tank includes a buffer chamber 60 and a filter chamber 70 separated by a partition 61. A filter device is arranged in the filter chamber 70. The filter device is a fish tank impurity filter device described in Example 1. Specifically, the guide cylinder 30 is arranged in the filter chamber; the partition 61 is provided with a plug interface, and the plug interface is plugged with the filter cylinder 20 of the filter device. The water inlet of the filter cylinder 20 is also provided with a limited flange 21 so that the plug interface supports the filter cylinder 20; the buffer cylinder 10 includes a main body and a tail, wherein the main body is arranged in the guide cylinder 30, and the tail is arranged at the bottom of the filter chamber 70. The main body and the tail are plugged, and the tail is provided with a sewage valve 11. The fish tank water enters the filter cylinder 20 through the buffer chamber 60, and is discharged from the bottom outlet of the filter chamber 70 after being filtered by the filter device.

[0030] Preferably, support plates are provided on both sides of the bottom of the buffer chamber, and the partition plate 61 is placed on the two support plates, so that the partition plate 61 and the buffer chamber 60 can be detachably connected, which is convenient for installation and maintenance of the filtering device.
