DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] refer to Figure 1 and Figure 2As shown, one embodiment of the present invention is a circulating fish tank filtration and drainage device, comprising a first filter cartridge 1, which is connected to a water inlet pipe 2 and a water outlet pipe 3, respectively. More importantly, a filter screen 4 is installed within the first filter cartridge 1. The filter screen 4 is tilted, specifically, tilted toward a feces collection trough 5, which is also installed within the first filter cartridge 1. The water outlet 21 of the water inlet pipe 2 is located above the filter screen 4, specifically at the upper end of the tilted filter screen 4. A filter cotton 6 is installed below the filter screen 4. Both the filter cotton 6 and the filter screen 4 are located in a passage between the first filter cartridge 1 and the water outlet pipe 3. Water entering the first filter cartridge 1 is filtered by the filter screen 4 and the filter cotton 6 before returning to the fish tank through the water outlet pipe 3. To facilitate the removal of waste from the feces collection trough 5, a drain outlet is provided on the side of the trough, extending to the exterior of the first filter cartridge 1. A drain valve 7 is installed on the drain outlet. At the same time, in order to prevent the filter material from clogging and causing water to overflow from the upper part of the filter box, an overflow port 8 can be further provided on the side of the first filter box 1. The overflow port 8 is located between the filter screen 4 and the filter cotton 6. Preferably, a top cover 10 can also be installed on the upper part of the first filter box 1.

[0019] In this embodiment, by obliquely installing the filter screen 4 inside the first filter box 1, after the water in the fish tank enters the first filter box 1 through the water inlet pipe 2, larger impurities remain on the filter screen 4 and slide into the feces collection trough 5 along the inclined direction of the filter screen 4 for storage. The water passing through the filter screen 4 is then filtered for the second time by the filter cotton 6 at the bottom, which not only improves the water filtration effect, but also facilitates the cleaning of impurities such as fish feces that are circulated and filtered.

[0020] As Figure 1 and Figure 2 As shown, in order to facilitate the integration of more filter materials in the filtering and sewage discharge device, a second filter box 20 and a third filter box 30 can be added therein, and the first filter box 1 is connected to the second filter box 20, the second filter box 20 is connected to the third filter box 30, and the outlet pipe 3 is connected to the third filter box 30, so that a variety of filter materials can be placed in the second filter box 20 and the third filter box 30. Water passing through a variety of filter materials in turn can help cultivate digestive bacteria and further purify the water quality.

[0021] The water in the fish tank enters the filter screen 4 in the first filter box 1 through the water inlet pipe and can be extracted by a water pump. Therefore, in this embodiment, the aforementioned water pump 9 is installed in the third filter box 30, and the water inlet end of the water pump 9 is connected to the water inlet of the water inlet pipe 2, and the water outlet end of the water pump 9 is connected to the water outlet 21 of the water inlet pipe 2.

[0022] On the other hand, Figure 3As shown, in another embodiment of the present invention, the water pump 9 can also be directly installed on the water inlet of the water inlet pipe 2, that is, the water pump is placed inside the fish tank when the device is in use.

[0023] refer to Figure 1-3 As shown, in actual use of the preferred embodiment of the present invention, the water in the fish tank is pumped into the first filter box 1 by starting the water pump 9. First, the fish feces and dirt in the water are screened out by the filter 4, and gradually roll into the feces collection tank 5 under the flushing effect of the water out of the water inlet pipe; then the water is further filtered by the filter cotton 6, and finally the clean water enters the second filter box 20 and the third filter box 30 filter box 2 for auxiliary consideration, and then returns to the fish tank through the outlet pipe 3. When the device is in use, the above process is continuously circulated. When it is necessary to discharge sewage, it is only necessary to open the sewage switch valve 7 on the sewage outlet to discharge the debris accumulated in the feces collection tank 5, which is convenient for cleaning.

[0024] In addition to the above, it should be noted that references to "one embodiment," "another embodiment," "an embodiment," and the like in this specification refer to specific features, structures, or characteristics described in conjunction with that embodiment as being included in at least one embodiment generally described in this application.
