Description

Technical Field

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

[0002] In many fields of modern society, water tanks are widely used as key equipment for storing and supplying liquids. Whether it is the storage of domestic water, the demand for cooling and process water in industrial production processes, or the water supply system in agricultural irrigation and commercial buildings, water tanks play an indispensable role. However, with the continuous improvement of people's requirements for water quality and the increasingly complex environment in which water tanks are used, traditional water tanks have exposed many difficult-to-overcome problems.

[0003] In terms of water quality, the water in the water tank is susceptible to a variety of pollution sources. Dust, microorganisms, harmful gases in the air can enter the water through the vents or gaps in the water tank. The water itself may also contain impurities such as silt and rust. In addition, under suitable temperature and environment, bacteria, algae and other microorganisms can easily breed and multiply, causing the water quality to deteriorate, produce odors, discoloration, and may even contain substances that are harmful to human health or industrial production.

[0004] In addition, traditional water tanks usually lack effective self-purification mechanisms and often rely on regular manual cleaning and water quality treatment. This method not only consumes a lot of manpower, material resources and time, but also makes it difficult to achieve timely maintenance in some special scenarios. For example, in water supply tanks in remote areas, due to their remote geographical location and inconvenient transportation, it is difficult for professional maintenance personnel to arrive at the site regularly for cleaning and maintenance; in some large-scale industrial production facilities, the number of water tanks is large and widely distributed, and the workload of manual cleaning and maintenance is huge, which is prone to untimely or inadequate maintenance. In addition, the water in ordinary water tanks has poor fluidity and is prone to forming dead water areas, which further increases the risk of water quality deterioration. At the same time, insufficient dissolved oxygen in water will also affect the quality and use of water. For example, in aquaculture tanks, insufficient dissolved oxygen will cause fish to die of hypoxia, affecting the benefits of aquaculture.

[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 capable of realizing gas-liquid dual circulation self-purification function, so as to effectively solve the above-mentioned problems. Summary of the invention

[0007] The present invention is intended to provide a gas-liquid dual-circulation self-purification water tank to solve the problem that traditional water tanks in the prior art often lack effective self-purification and circulation systems, making it difficult to ensure the long-term stability and cleanliness of water quality.

The flow limiting device 9 includes a flow limiting groove 901 symmetrically provided at the water outlet of the circulating water pipe 402, a flow limiting rod 902 is movably embedded in the flow limiting groove 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, a return spring 905 is symmetrically provided above the flow limiting ring 906, the upper part of the return spring 905 is 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, and the lower end of the conical column 904 is connected to the inner wall of the box body 1. The inner wall of the circulating water pipe 402 is adapted in size. When the liquid flows out and generates pressure, it pushes the flow limiting plate 903 to move downward, stretching the reset spring 905, causing the flow limiting rod 902 to drop in the flow limiting groove 901, and the conical column 904 partially leaves the inner wall of the circulating water pipe 402. The greater the pressure, the greater the range of the conical column 904 to be separated, 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 automatic adjustment of the liquid circulation flow rate, and being able to seal the circulating water pipe 402 when not circulating;

[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 0.1-0.5mm. 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 also help maintain the stability of the water quality and avoid water pollution caused by 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 then is pressed into the filter box 303. In the filter box 303, the air passes through the filter plate 304 made of activated carbon fiber and HEPA filter material in turn, and 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 transmission fan 506, so that the transmission shaft 502 starts to rotate. The rotation of the transmission shaft 502 drives the rotation of the rotating shaft 601, and the two sets of rotating fans 602 on the rotating shaft 601 rotate accordingly. The rotating fans 602 stirs the liquid in the containing chamber 101 so that the liquid is fully in contact with the air discharged from the air outlet 305. In this process, the oxygen in the air gradually dissolves into the water, increasing the amount of dissolved oxygen in the water. At the same time, some volatile harmful substances in the water, such as chlorine and hydrogen sulfide, evaporate into the air and are discharged from the box body 1 through the air outlet 102. The rotation of the rotating shaft 601 drives the driven shaft 803 to rotate 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 inlet of the circulating water pipe 402. The water inlet rotates to generate suction. Under the action of suction, the liquid in the accommodating 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 layers of filter screens 404 with different precisions. Suspended particles in the water, such as silt, rust, etc., are intercepted and filtered out by the filter screens. The filtered liquid continues to flow in the circulating water pipe 402. When it reaches the water outlet, the flow limiting device 9 automatically adjusts the outflow speed of the liquid according to the pressure received, and the liquid pushes the flow limiting plate 903 downward. Move, stretch the reset spring 905, so that the flow limiting rod 902 moves 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 reset spring 905 returns to its original state, pushing 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, thereby realizing automatic adjustment of the liquid circulation flow rate. The liquid adjusted by the flow limiting device 9 returns to the containing chamber 101 from the water outlet.
