Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a fish tank water filtration and circulation device. Background Technology

[0002] Water quality is crucial when keeping fish in an aquarium. If the water isn't changed regularly, it will gradually deteriorate, producing insoluble particles and soluble toxins from the decomposition of organic matter, such as ammonia, nitrite, and even nitrates. Therefore, an aquarium water filtration and circulation system is needed to intercept insoluble particles and remove soluble toxins. Various filtration methods exist. Overflow filters typically use filter media for physical filtration, followed by a nitrification system composed of at least two types of filter media, such as bio-foam, bio-balls, ceramic rings, or volcanic rock, to decompose soluble toxins. Both the filter media and bio-foam require cleaning or replacement during use. However, replacing the filter media and bio-foam in existing overflow filters, especially when located at the back of the aquarium, can be difficult. Utility Model Content

[0003] This invention aims to address the shortcomings of existing technologies by providing a fish tank water filtration and circulation device.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A fish tank water filtration and circulation device includes a filter tank, an inlet pipe, a water pump, and an outlet pipe.

[0017] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-4 As shown, a fish tank water filtration and circulation device includes a filter tank 1, an inlet pipe 2, a water pump 3, and an outlet pipe 4. The filter tank 1 has a first water-discharging plate 10, a second water-discharging plate 11, and a third water-discharging plate 12 arranged sequentially from right to left. These plates divide the filter tank 1 into a physical filtration chamber 13, a first nitrification chamber 14, a second nitrification chamber 15, and a clear water chamber 16, arranged sequentially from right to left. Each of the physical filtration chambers 13, the first nitrification chamber 14, and the second nitrification chamber 15 has four sliding rails 5 and a filter media box 6, respectively. The sliding rails 5 are fixedly installed in pairs on the filter tank. On the inner sides of the front and rear walls of the filter tank 1, a row of pulleys 50 are rotatably installed inside the slide rails 5. The filter media box 6 has fixed locking blocks 60 on its front and rear walls, which are slidably connected to the corresponding slide rails 5 on both sides. The filter media box 6 includes a filter housing 61 and a filter cover 62. The filter housing 61 has an upper water passage hole 610 and a lower water passage hole 611 on its left and right side walls, respectively. The filter cover 62 has a top water passage hole 620. The lower end of the inlet pipe 2 leads into the physical filtration chamber 13. The water pump 3 is placed inside the clear water chamber 16 and is fixedly connected to the lower end of the outlet pipe 4. The filter media box 6 in the physical filtration chamber 13 is filled with filter cotton. The filter media boxes 6 in the first nitrification chamber 14 and the second nitrification chamber 15 are filled with at least two types of filter media, including biochemical cotton, bacterial houses, ceramic rings, or volcanic rock, respectively. When using the device, place the filter media box 6 into the corresponding compartment along the slide rail 5. When the filter media needs to be replaced or cleaned, remove the filter media box 6 along the slide rail 5. The water to be filtered enters the filter media box 6 through the upper water inlet 610 and the top water inlet 620, and flows out through the lower water inlet 611 after filtration.

[0020] The height of the left side of the first water-discharging plate 10 is greater than the height of the left side of the second water-discharging plate 11, and the height of the left side of the second water-discharging plate 11 is greater than the height of the left side of the third water-discharging plate 12. This achieves overflow filtration of the aquarium water.

[0021] The filter housing 61 has a sliding groove 612 on the inner side of its top, and the filter cover 62 has sliders 621 fixed on its front and rear sides. The sliders 621 are slidably connected to the corresponding sliding grooves 612. When replacing the filter media in the filter media box 6, the filter cover 62 can be pulled directly to the right to expose the inside of the filter housing 61.

[0022] A handle 622 is fixedly provided in the middle of the filter cover 62. This facilitates the removal of the filter media box 6 and can also be used to pull the filter cover 62.

[0023] A locking block 63 is fixedly installed at the bottom of the filter media box 6, and a spring-loaded ball lock 17 is provided at the bottom of the filter cylinder 1 corresponding to the position of the locking block 63. The locking block 63 and the spring-loaded ball lock 17 are engaged. This is used to fix the position of the filter media box 6 and prevent the filter media box 6 from floating.

[0024] It also includes: a float probe 160, a counterweight 161, and a controller 162. The float probe 160 is suspended inside the clear water tank 16, and the counterweight 161 is connected to the float probe 160. The output end of the float probe 160 is connected to the controller 162, which is electrically connected to the water pump 3 and controls the water pump 3. The controller 162 is a PLC, and a Siemens S7-200 series model can be selected. When the float probe 160 is submerged in water, the float rises, the clear water tank 16 has sufficient water, and the controller 162 will control the water pump 3 to continuously supply water to the aquarium. When the float probe 160 is not in contact with the water surface, the clear water tank 16 is in a water-deficient state, and the controller 162 will control the water pump 3 to shut down to prevent the water pump 3 from running dry.

[0025] The method of using this utility model is as follows: Fill the filter media box 6 with suitable filter cotton and filter media, and place it into the corresponding chamber along the slide rail 5. Water from the aquarium is introduced into the physical filtration chamber 13 through the inlet pipe 2 for physical filtration to remove insoluble particles. Then, the water enters the first nitrification chamber 14 through the first tipping plate 10, and the second nitrification chamber 15 through the second tipping plate 11 for nitrification to remove soluble toxins. Finally, the water enters the clear water chamber 16 through the third tipping plate 12. The filtered aquarium water is then reintroduced into the aquarium through the outlet pipe 4 by the water pump 3 for circulation. When it is necessary to clean the filter cotton and filter media, lift the handle 622 upwards, slide the filter media box 6 upwards along the slide rail 5 to remove it, and pull the filter cover 62 to the right for easy removal or insertion of filter cotton and filter media.

[0026] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
