Description

Technical Field

[0001] The present invention relates to a fish tank electrolyzed water ozone sterilization water circulation control system. Background Art

[0002] After a fish tank has been used to raise fish for a period of time, residues, excrements, corpses and other impurities will accumulate in the fish tank. At the same time, the water quality in the fish tank will deteriorate, affecting the survival of the fish. For this reason, the Chinese invention patent with the publication number CN109699559B discloses "A self-purifying water circulation fish tank", and another Chinese invention patent with the publication number CN211185496U discloses "A water circulation fish tank LED ultraviolet sterilization device". However, the existing fish tanks have two obvious defects: First, although the existing fish tanks can achieve water circulation, this water circulation can only be carried out when the water pump is working. If the water pump is turned off, the water circulation will also stop. If it is always on, it will consume a lot of electricity. Second, although the existing fish tanks already have the functions of filtering and sterilizing water, they can only filter out some residues, excrements, corpses and other impurities. A large part of them will still accumulate at the bottom of the fish tank and need to be manually cleaned, and even the fish tank needs to be emptied to remove them. Summary of the Invention

The rollers are driven by a driving motor. A slider is respectively arranged on each of the two guide rails. An installation cavity is formed inside one of the sliders. A screw rod with one end extending out of the slider is rotatably arranged in the installation cavity. The screw rod is slidably arranged on the guide rail. A spiral groove is formed on the outer wall of the screw rod. A pull rope is arranged between the roller and the screw rod.

[0007] Further improvement: A conical cylinder is arranged at the suction inlet of the suction nozzle. The large end of the conical cylinder faces outward, and the small end of the conical cylinder is connected to the inner wall of the suction nozzle.

[0009] Further improvement: The impurity cleaning device includes a group of rotating rollers arranged at the bottom of the fish tank. A belt is arranged on the rotating rollers.

The ozone generator in the sterilization chamber generates ozone for sterilization and disinfection. Since both the sterilization chamber and the water storage tank are airtight, the increased water in the sterilization chamber increases the air pressure in the sterilization chamber. The increased air pressure enters the water storage tank through the connecting pipe, and the air pressure in the water storage tank also increases accordingly. Under the action of the air pressure, the water in the water storage tank is re-transported to the fish tank through the countercurrent pipe, realizing a water cycle. When the water in the water storage tank decreases to a certain extent, the water level detector obtains a signal and the return water pump works, and the water in the sterilization chamber is input into the water storage tank. When the pressure in the sterilization chamber becomes smaller, the water and gas in the fish tank are replenished through the filtration channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described in detail below with reference to the embodiments of the drawings.

[0021] Embodiment 1

[0022] In this embodiment, the electrolyzed water ozone sterilization water circulation control system of the fish tank includes a fish tank 1, a sterilization chamber 2, a filtration channel 4, a connecting pipe 5, a water storage tank 3, a countercurrent pipe 31, a return water pipe 211, a return water pump 21, an electrolytic ozone generator 22, a fine-pore material filtration layer 42, an ultra-porous material filtration layer 43, and an impurity cleaning device.

[0023] Among them, a sterilization chamber 2 is provided below the fish tank 1. A sealed water storage tank 3 and a filtration channel 4 are provided between the fish tank 1 and the sterilization chamber 2. The filtration channel 4 communicates with the bottom of the fish tank 1 and the sterilization chamber 2. A connecting pipe 5 is provided between the upper part of the sterilization chamber 2 and the water storage tank 3. A return water pump 21 is provided in the sterilization chamber 2. The return water pump 21 is communicated with the water storage tank 3 through a return water pipe 211. A countercurrent pipe 31 and a water level detector are provided in the water storage tank 3. The lower end of the countercurrent pipe 31 is located at the bottom of the water storage tank 3, and the upper end of the countercurrent pipe 31 is located above the fish tank 1. The water level detector is electrically connected to the return water pump 21. An electrolytic ozone generator 22 is provided in the sterilization chamber 2. A fine pore material filter layer 42 and a highly porous material filter layer 43 are provided in the filtration channel 4. The material used for the fine pore material filter layer 42, such as biochemical cotton and activated carbon, mainly physically filters some toxin-producing substances, such as filtering out residual baits, excrements, corpses and other impurities. The highly porous material filter layer 43 has a certain toxin decomposition ability. In the highly porous material filter layer 43, there are microorganisms with toxin decomposition ability such as photosynthetic bacteria and nitrifying bacteria, and the highly porous material filter layer provides an epiphytic environment for these microorganisms.

[0024] When the water pump 21 is not working, the water in the fish tank 1 will pass through the filtration channel 4, sequentially pass through the fine pore material filter layer 42 and the highly porous material filter layer 43 for filtration, and then enter the sterilization chamber 2. The ozone generator 22 in the sterilization chamber 2 generates ozone for sterilization and disinfection. Since both the sterilization chamber 2 and the water storage tank 3 are sealed, the increased water in the sterilization chamber 2 causes the air pressure in the sterilization chamber 2 to increase. The increased air pressure enters the water storage tank 3 through the connecting pipe 5, and the air pressure in the water storage tank 3 also increases accordingly. Under the action of the air pressure, the water in the water storage tank 3 is re-transported into the fish tank 1 through the countercurrent pipe 31, realizing a water circulation. When the water in the water storage tank 3 decreases to a certain extent, the water level detector obtains a signal, and the return water pump 21 works. The water in the sterilization chamber 2 is input into the water storage tank 3. When the pressure in the sterilization chamber 2 becomes smaller, the water and gas in the fish tank 1 are replenished through the filtration channel 4.

[0025] In addition, an impurity cleaning device is also designed in this embodiment. The impurity cleaning device is mainly used to clean most of the other toxin substances deposited at the bottom of the fish tank 1, such as residual baits, excrements, corpses and other impurities. Because the above-mentioned filtration channel 4 can only filter a part of the toxin substances, and most of the existing toxin substances need to be manually cleaned over time, and even the fish tank needs to be emptied for cleaning.

[0026] Therefore, the present invention also designs a special impurity cleaning device, aiming at the permanent use of the fish tank 1 without the need for manual cleaning of the fish tank. As Figure 2As shown in the figure, in this embodiment, the impurity cleaning device includes a set of cylindrical guide rails 61 arranged at the bottom of the fish tank 1, and a roller 64 arranged above the fish tank 1. The roller 64 is driven by a driving motor. A slider 62 is arranged on each of the two guide rails 61. An installation cavity 621 is formed inside one of the sliders 62. A screw rod 63 with one end extending out of the slider 62 is rotatably arranged in the installation cavity 621. The screw rod 63 is slidably arranged on the guide rail 61. A spiral groove 631 is formed on the outer wall of the screw rod 63. A pull rope 641 is arranged between the roller 64 and the screw rod 63. One end of the pull rope 641 bypasses the roller 64, and the other end of the pull rope 641 is wound around the spiral groove 631 of the screw rod 63 in multiple strands. A first bevel gear 651 is coaxially arranged at the other end of the screw rod 63. A second bevel gear 652 meshing with the first bevel gear 651 is arranged in the installation cavity 621. A hollow rotating shaft 66 is arranged between the two guide rails 61. One end of the rotating shaft 66 is coaxially connected to the second bevel gear 652, and the other end of the rotating shaft 66 is rotatably arranged on the other slider 62. A plurality of suction nozzles 67 communicating with the inner cavity of the rotating shaft 66 are arranged on the rotating shaft 66. The inner cavity of the rotating shaft 66 is connected to an external water suction pump.

[0027] Further, minor modifications can be made to the above-mentioned impurity cleaning device. Specifically, the cylindrical guide rail 61 is rotatably arranged at the bottom of the fish tank 1. A guiding strip is arranged on the outer side wall of the guide rail 61 along the length direction of the guide rail 61. The slider 62 is slidably arranged on the guide rail 61, and the screw rod 64 is rotatably arranged on the slider 62, and there is no connection relationship between the screw rod 64 and the guide rail 61.

[0028] Furthermore, the other slider 62 has the same structure as one of the sliders 62. Two pull ropes 641 are arranged on the roller 64, and the other pull rope 641 is arranged between the roller 64 and the screw rod 63 on the other slider 62.

[0029] When cleaning is required, the drive motor can drive the roller 64 to rotate. The roller 64 drives the screw rod 63 to move through the pull rope 641. During the process of the roller 64 driving the pull rope 641 to move, the pull rope 641 moves successively within the spiral groove 631 of the screw rod 63, causing the screw rod 63 to have two motions. On the one hand, the screw rod 63 will rotate, and the rotation of the screw rod 63 will drive the first bevel gear 651 to rotate. The first bevel gear 651 drives the rotating shaft 66 to rotate through the meshing second bevel gear 652. On the other hand, the screw rod 63 will also pull the slider 62 to move on the guide rail 61. When the drive motor rotates in the reverse direction, the rotation direction of the rotating shaft 66 and the sliding direction of the slider 62 both reverse. In this way, while each suction nozzle 67 on the rotating shaft 66 rotates around the rotating shaft 66, the suction nozzle 67 can also move along the bottom of the fish tank 1, and the suction nozzle 67 can suck away the impurities at the bottom of the fish tank 1. At the same time, the rotating suction nozzle 67 also has the function of a water turning wheel and can also adsorb the agitated impurities.

[0030] Furthermore, in order to improve the adsorption capacity, a conical cylinder 671 is provided at the suction inlet of the suction nozzle 67. The large end of the conical cylinder 671 faces outward, and the small end of the conical cylinder 671 is connected to the inner wall of the suction nozzle 67, forming a negative pressure channel between the outer wall of the conical cylinder 671 and the suction inlet of the suction nozzle 67. By designing a conical cylinder 671 structure at the suction inlet of the suction nozzle 67, during the process of water flow passing through the conical cylinder 671 of the suction nozzle 67, the water flow changes from thick to thin, accelerating the flow rate of the water flow, causing a negative pressure area to form outside the suction inlet of the suction nozzle 67. This negative pressure area can cause impurities to gather and be sucked into the suction nozzle 67 under the action of negative pressure, thereby improving the adsorption capacity of the impurities.

[0031] Embodiment 2

[0032] The difference technical feature of Embodiment 2 compared with Embodiment 1 lies in the different impurity cleaning device. In this embodiment, as Figure 3 and 4 shown, the impurity cleaning device includes a group of rotating rollers 71 arranged at the bottom of the fish tank 1. A belt 72 is provided on the rotating rollers 71. One of the rotating rollers 71 extends outside the fish tank 1 and is connected to a cleaning motor 73. A cleaning brush 721 is provided on the belt 72.

[0033] Furthermore, the bottom of the fish tank 1 is a concave semi-cylindrical shape, and the cleaning brush 721 is semi-cylindrical, facilitating the cleaning of the fish tank 1.

[0034] At the same time, a filter basket 41 is provided at the top of the filter channel 4. Filter holes with primary filtering functions are provided on the outer side wall of the filter basket 41. A sealed door for taking out the filter basket 41 is provided on the side wall of the filter channel 4. First valves 81 are provided on the filter channel 4 above and below the filter basket 41. A discharge pipe 414 is connected to the lower side of the filter basket 41 on the filter channel 4, and a second valve 82 is provided on the discharge pipe 414.

[0035] In this embodiment, the impurity cleaning method is to use the belt 72 to drive the cleaning brush 721 to clean the bottom of the fish tank 1. When the cleaning brush 721 moves to the bottom of the belt 72, the cleaning brush 721 can just sweep the impurities at the bottom of the fish tank 1 into the filter basket 41 at the top of the filter channel 4 in one direction. When the cleaning brush 721 moves above the belt 72, the cleaning brush 721 will not sweep the impurities back to the other side of the bottom of the fish tank 1 in the reverse direction. In this way, after the cleaning is completed, open the sealed door on the filter channel 4, take out the filter basket 41, and pour out the impurities.

[0036] Embodiment 3

[0037] As Figure 5 shown, the difference technical feature of Embodiment 3 compared with Embodiment 2 is that an outer frame 411 with an inverted trapezoidal cross-section is provided at the top of the filter channel 4. Filter holes are opened on the outer frame 411. The filter basket 41 is rotatably arranged in the outer frame 411. The bottom of the outer frame 411 is connected with a sealing box 412. A stirring motor 413 is arranged in the sealing box 412. The stirring motor 413 is connected with the bottom of the filter basket 41. A shear channel is formed between the outside of the filter basket 41 and the inner wall of the outer frame 411. First valves 81 are arranged on the filter channel 4 on the upper and lower sides of the filter basket 41. A drain pipe 414 is communicated with the filter channel 4 below the filter basket 41. A second valve 82 is arranged on the drain pipe 414. Further, the top of the filter basket 41 can extend into the fish tank 1, and a rotating vane is arranged at the top of the filter basket 41. In this embodiment, the stirring motor 413 can be used to drive the filter basket 41 to rotate. A vortex is formed during the rotation of the filter basket 41, and the impurities are disturbed. When the filter basket 41 stops, the impurities float into the filter basket 41 to realize the negative pressure adsorption function.
