DETAILED DESCRIPTION

[0026] The following will be combined with 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. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 to Figure 6 As shown, this embodiment proposes a double-layer circulation filtering fish tank, including a tank body 1 and a filter bin 6, the tank body 1 includes a fish farming area 2 and a water discharge area 3, the fish farming area 2 and the water discharge area 3 are separated by a water filter plate 4, the inner wall of the tank body 1 is provided with a slot, the water filter plate 4 is embedded in the slot and fixedly installed, and the end of the water filter plate 4 facing the bottom of the tank body 1 is provided with a plurality of filter holes 41, the filter holes 41 penetrate the water filter plate 4 to connect the fish farming area 2 and the water discharge area 3, and the filter holes 41 are distributed in an array along the edge of the water filter cup, and the more the number, the higher the water filtering efficiency. In addition, the filter holes 41 are to ensure that water and pollutants can pass normally, but fish cannot swim to the water discharge area 3 through the filter holes 41, so the size of the filter holes 41 needs to be smaller than the size of the fish to be raised. A sewage pipe 31 and a second water inlet pipe 33 are provided in the sewage area 3. One end of the sewage pipe 31 is located in the sewage area 3. The second water inlet pipe 33 is passed through the partition 61. One end of the second water inlet pipe 33 is connected to the fish farming area 2. The other ends of the second water inlet pipe 33 and the sewage pipe 31 are both connected to the sewage discharge component 5.

[0028] The sewage assembly 5 includes a filter 51 and a sewage pump 52. The sewage pump 52 provides power, and the filter 51 filters large particles of pollutants in the water. One end of the filter 51 is connected to the sewage pipe 31, and the other end of the filter 51 is connected to the water inlet of the sewage pump 52. The water outlet of the sewage pump 52 is connected to the second water inlet pipe 33. A switch valve 53 is also provided between the second water inlet pipe 33 and the filter 51. After the sewage pump 52 is turned off, a large amount of water remains in the sewage pipe 31. When cleaning the filter 51 or repairing the sewage pump 52, the switch valve 53 needs to be closed to empty the water in the sewage pipe 31. A drainage plate 32 is installed at one end of the sewage pipe 31 located in the water discharge area 3, and a suction cup 36 is installed on the side of the drainage plate 32 away from the sewage pipe 31. The suction cup 36 can fix the position of the drainage plate 32, and also indirectly fix the position of the sewage pipe 31. The projection surface of the drainage plate 32 is a right-angled triangle structure. The three sides of the drainage plate 32 are provided with drainage openings connected to the sewage pipe 31. The hypotenuse of the largest opening of the drainage plate 32 faces the filter hole 41. The hypotenuse opening is the largest and has a larger water flow rate, serving as the main suction port of the drainage plate 32. The opening of the right-angled side is smaller and serves as the auxiliary suction port of the drainage plate 32, which is used to absorb pollutants closer to the drainage plate 32.

[0029] When the sewage pump 52 is turned on, suction is generated at the drainage disc 32, thereby driving the water at the bottom of the cylinder body 1 to flow to the drainage disc 32, and at the same time, the feces and other pollutants at the bottom of the water flow to the drainage disc 32 together with the water flow, and the water with pollutants flows through the filter hole 41, passes through the drainage disc 32 and enters the sewage pipe 31, and after passing through the filter 51, the large particles of pollutants and water are separated, and the filtered water passes through the sewage pump 52 and then reaches the second water inlet pipe 33, and returns to the fish farming area 2. The filtration of large particles of pollutants reduces the burden of the filter chamber 6, and at the same time, because only large particles of pollutants are filtered, the filtration efficiency of the filter is high, the water flow of the second water inlet pipe 33 and the sewage pipe 31 is relatively large, and the sewage discharge effect of the pollutants at the bottom of the cylinder is good.

[0030] The lower layer of the double-layer circulation filtering fish tank is the filtering bin 6, and the lower water area 3 is provided with a first water inlet pipe 34 and a lower water pipe 35. The first water inlet pipe 34 is penetrated by the partition 61, and one end of the first water inlet pipe 34 is connected with the fish farming area 2. The lower water pipe 35 is penetrated by the fish tank and the filtering bin 6. The lower water pipe 35 is located at one end of the lower water area 3 which is lower than the highest point of the partition 61. The height of the lower water pipe 35 in the lower water area 3 determines the highest water level line of the fish farming area 2 of the cylinder body 1. When the first water inlet pipe 34 injects water into the cylinder body 1, the water level in the cylinder body 1 rises, and the overflowing water flows into the lower water pipe 35, and the lower water pipe 35 is connected with the filtering bin 6. In addition, the down pipe 35 has a height adjustable function. The down pipe 35 includes a main pipe 351 and a secondary pipe 352. The main pipe 351 is provided with an external thread on its outer circumferential surface at one end of the down pipe 3. The secondary pipe 352 is provided with an internal thread on its inner circumferential surface at one end thereof to be screwed to the main pipe 351. In addition, a step 353 is provided around the inner wall of the secondary pipe 352. The step 353 and the inner wall of the secondary pipe 352 are integrally formed. A sealing ring 354 is provided on the side of the step 353 facing the main pipe 351. One side of the sealing ring 354 abuts against the step 353, and the other side of the sealing ring 354 abuts against one end of the main pipe 351. The design of the step 353 and the sealing ring 354 increases the sealing effect between the main pipe 351 and the secondary pipe 352. When it is necessary to raise fish with low water level requirements, the secondary pipe 352 is rotated counterclockwise and the secondary pipe 352 is removed to lower the water level of the fish farming area 2. At this time, the height of the main pipe 351 is the new water level.

[0031] The filter chamber 6 is divided into several areas by a plurality of partitions 61 and baffles 62. An overflow port 63 is provided at one end of the partition 61 facing the bottom of the water. The partitions 61 and baffles 62 are staggered to form an S-shaped water passage. The height of the baffles 62 is successively reduced according to the order of water filtration. The staggered arrangement of the partitions 61 and baffles 62 allows water to flow only through overflow between the divided areas of the filter chamber 6. The height of the baffles 62 is successively reduced according to the order of water filtration, so that there is a water pressure difference between the various areas of the filter chamber 6, which increases the speed of water flow in the filter chamber 6. According to the function, the various areas of the filter chamber 6 can be divided into a physical area, a biochemical area, a submersible pump area and a sewage pump area. The sewage pump is used to place the sewage pump and is not connected to other areas. The water in the downpipe 35 first enters the physical area, then passes through the biochemical area, and finally flows to the submersible pump area. The submersible pump pumps the filtered water back to the cylinder 1 to form a cycle.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
