Description

Technical Field

[0001] The present invention relates to the technical field of water tanks, in particular to a gas-liquid dual-circulation self-purification water tank. Background Art

[0002] Water tanks are widely used in many areas of modern society as key equipment for storing and supplying liquids. Whether storing domestic water, meeting cooling and process water needs in industrial production processes, or supplying water to agricultural irrigation and commercial buildings, water tanks play an indispensable role. However, with increasing demands for water quality and the increasingly complex environments in which water tanks are used, traditional water tanks are facing numerous challenges.

[0003] Regarding water quality, the water in the tank is susceptible to a variety of contaminants. Dust, microorganisms, and harmful gases from the air can enter the water through the tank's vents or gaps. The water itself may also contain impurities such as silt and rust. Furthermore, under suitable temperatures and conditions, microorganisms such as bacteria and algae can easily thrive and multiply, causing the water to deteriorate, produce odors, discolor, and even contain substances that are harmful to human health or industrial production.

[0004] Furthermore, traditional water tanks typically lack effective self-purification mechanisms and often rely on regular manual cleaning and water treatment. This approach not only consumes significant manpower, material resources, and time, but also makes timely maintenance difficult in some special scenarios. For example, water supply tanks in remote areas are geographically isolated and difficult to access, making it difficult for professional maintenance personnel to regularly arrive on-site for cleaning and maintenance. In some large-scale industrial production facilities, water tanks are numerous and widely distributed, creating a significant workload for manual cleaning and maintenance, making it easy for maintenance to be delayed or inadequate. Furthermore, the water in ordinary water tanks has poor fluidity, making it easy for stagnant water areas to form, further exacerbating the risk of water quality deterioration. Furthermore, insufficient dissolved oxygen in water can also affect its quality and effectiveness. For example, in aquaculture tanks, insufficient dissolved oxygen can cause fish to die from lack of oxygen, impacting aquaculture profitability.

[0005] In view of the many problems existing in the above-mentioned traditional water tanks, it has become an urgent need to develop a water tank with efficient self-purification function, capable of realizing gas-liquid dual circulation and automatic adjustment. This water tank can effectively solve the problem of water pollution, reduce manual maintenance costs and workload, and improve the fluidity and dissolved oxygen content of the water in the water tank, thereby ensuring that a stable, clean and compliant water source can be provided in various application scenarios.

[0006] Therefore, the present invention aims to provide a water tank that can realize the gas-liquid dual circulation self-purification function, so as to effectively solve the above problems. Summary of the Invention

The flow-limiting device 9 includes flow-limiting grooves 901 symmetrically opened at the water outlet of the circulating water pipe 402. A flow-limiting rod 902 is movably clamped in the flow-limiting grooves 901. A flow-limiting ring 906 is fixedly provided above the flow-limiting rod 902. The flow-limiting ring 906 is movably adapted to the surface of the circulating water pipe 402. Reset springs 905 are symmetrically provided above the flow-limiting ring 906. The upper parts of the reset springs 905 are fixedly connected to the upper part of the inner wall of the box body 1. A flow-limiting plate 903 is fixedly provided below the flow-limiting rod 902. A conical column 904 is fixedly provided above the flow-limiting plate 903. The lowermost end of the conical column 904 is adapted to the inner wall of the circulating water pipe 402 in size. When pressure is generated by the outflow of the liquid, it will push the flow-limiting plate 903 to move downward, stretch the reset spring 905, and cause the flow-limiting rod 902 to descend in the flow-limiting groove 901, and a part of the conical column 904 leaves the inner wall of the circulating water pipe 402. The greater the pressure, the greater the range of separation of the conical column 904 and the greater the flow rate. When the liquid pressure decreases, the reset spring 905 returns to its original state, pulling the flow-limiting plate 903 to move upward, and the conical column 904 fits tightly with the inner wall of the circulating water pipe 402 again, reducing the liquid outflow speed, realizing the automatic adjustment of the liquid circulation flow rate, and being able to seal the circulating water pipe 402 when not in circulation;

[0054] The inner wall of the box body 1 is coated with an anti-corrosion coating, which is an epoxy resin coating with a coating thickness of 0.1 - 0.5 mm. This anti-corrosion coating can effectively prevent the inner wall of the box body 1 from being corroded by water and impurities in the water, extend the service life of the water tank, and at the same time help maintain the stability of the water quality and avoid water quality pollution caused by the corrosion of the inner wall of the water tank.

[0055] Working principle: Start the air pump 301. The outside air enters the air pump 301 through the air inlet 302 and is then pressed into the filter box 303. Inside the filter box 303, the air successively passes through the filter plates 304 made of activated carbon fiber and HEPA filter material. Impurities such as dust, pollen, and harmful gases are effectively filtered out. The purified air is discharged from the air outlet 305 and blows the drive fan 506, causing the drive shaft 502 to start rotating. The rotation of the drive shaft 502 drives the rotation of the rotating shaft 601. The two groups of rotating fans 602 on the rotating shaft 601 rotate accordingly. The rotating fans 602 stir the liquid in the accommodation chamber 101, enabling the liquid to fully contact the air discharged from the air outlet 305. During this process, the oxygen in the air gradually dissolves into the water, increasing the dissolved oxygen in the water. At the same time, some volatile harmful substances in the water, such as chlorine and hydrogen sulfide, volatilize into the air and are discharged from the box body 1 through the exhaust port 102. The rotation of the rotating shaft 601 drives the rotation of the driven shaft 803 through the transmission of the first gear 701, the power belt 702, and the second gear 703. The driven fan 805 below the driven shaft 803 rotates at the water inlet of the circulating water pipe 402, generating suction. Under the action of the suction, the liquid in the accommodation chamber 101 enters the circulating water pipe 402 through the water inlet of the circulating water pipe 402. When the liquid flows in the circulating water pipe 402, it first passes through multiple filter meshes 404 with different precisions. Suspended particles in the water, such as sediment and rust, are intercepted and filtered out by the filter meshes. The filtered liquid continues to flow in the circulating water pipe 402. When it reaches the water outlet, according to the magnitude of the liquid pressure, the flow-limiting device 9 automatically adjusts the outflow speed of the liquid according to the pressure it receives. The liquid pushes the flow-limiting plate 903 downward, stretching the return spring 905, causing the flow-limiting rod 902 to move downward in the flow-limiting groove 901, and the conical column 904 partially leaves the inner wall of the circulating water pipe 402, thereby increasing the outflow channel of the liquid and increasing the liquid outflow speed. When the liquid pressure decreases, the return spring 905 returns to its original state, pushing the flow-limiting plate 903 upward, and the conical column 904 closely fits the inner wall of the circulating water pipe 402 again, reducing the liquid outflow speed, realizing the automatic adjustment of the circulating flow rate of the liquid. The liquid adjusted by the flow-limiting device 9 returns to the accommodation chamber 101 from the water outlet.
