Description

Technical Field

[0001] The utility model belongs to the technical field of fish tank separation equipment, and specifically relates to a fish feces separation device for a fish tank and a fish tank. Background Art

[0002] In order to ensure the quality of the water in the fish tank, the tank needs to be equipped with a fish feces separation device, and the water in the fish tank needs to be filtered regularly or continuously to separate the fish feces, and then the water after the fish feces are separated is sent back into the tank for use. There are filtration systems on the market that are set inside the fish tank (back or side) to filter the fish feces in the water. This filtration system first uses physical methods such as filter cotton to filter, and then uses biological filter materials to filter, and the filtered water re-enters the tank. This method has defects: the water containing a large volume of fish feces is first filtered by physical methods such as filter cotton to filter the fish feces and impurities. This practice easily causes the filter cotton to be blocked, and the filter cotton needs to be cleaned or replaced frequently; at the same time, the fish feces are intercepted by the filter cotton and stay on the filter cotton. After the water body flushes the filter cotton for a long time, the fish feces will be dispersed into small particles, thereby blocking the biological filter material behind. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0027] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] It should be noted that in order to better display the internal structure of the functional area and the structure of the base box 10, Figure 2 and Figure 3 The back plate of the cylinder body 1 and the back plate of the base box body 10 are not shown in the figure, that is, the back plate of the cylinder body 1 and the back plate of the base box body 10 are removed. Figure 4 It is a schematic diagram with the top plate of cylinder body 1 removed.

[0029] like Figure 1-5As shown, the utility model discloses a fish excrement separation device for a fish tank, comprising a functional area arranged inside a tank body 1 and a fish excrement separator 18 arranged outside the tank body 1, wherein the functional area comprises a sewage area 16, a filter area 19 and a clean water area 17 arranged in sequence in a horizontal direction, a water outlet 6 is arranged at the bottom of the sewage area 16, a water inlet 7 is arranged at the bottom of the clean water area 17, and the liquid inlet end and the outlet end of the fish excrement separator 18 are respectively connected with the water outlet 6 and the water inlet 7 through pipelines; a filter material is arranged in the filter area 19, and the liquid in the sewage area 16 enters the filter area 19 from the upper part thereof, and enters the clean water area 17 after being filtered by the filter material. A water return component is arranged in the clean water area 17, and the water return component sends the clean water in the clean water area 17 to the viewing area 15.

[0030] The viewing area 15 is used as an area for aquatic animals and plants to move and grow, and aquatic animals produce feces when they move therein. The water containing fish feces in the viewing area 15 enters the functional area. Since the fish feces have a certain weight and the water inlet 7 is arranged at the bottom of the sewage area 16, the sewage containing heavy feces will gather at the bottom of the sewage area 16 and be discharged from the water outlet 6. After being filtered by the fish feces separator 18, it will enter the water purification area 17 through the water inlet 7. The clean water in the water purification area 17 will re-enter the viewing area 15 through the water return component. Light feces are located in the middle and upper part of the sewage area 16, enter the filter area 19 for filtration, and then enter the water purification area 17. By setting the filter area 19 for filtering small and light feces, and the fish feces separator 18 for filtering large and heavy feces, the problem of easy clogging of the filter cotton in the filter area 19 is solved. At the same time, the functional area is arranged inside the cylinder body 1 to save space, which is particularly suitable for the separation of fish feces in small-volume fish tanks.

A notch 20 is provided at the lower end of the first vertical partition 2 near the sewage area 16. Since fish feces have a certain weight, the fish feces in the ornamental area 15 enter the sewage area 16 through the notch 20. The water in the ornamental area 15 can only enter the sewage area 16 through the water hole 14 and the notch 20.

[0032] A preferred technical solution is that an upper water hole is provided on the upper part of the first vertical partition 2, and at least one lower water hole is provided on the lower part of the first vertical partition 2.
