Description
Technical Field
[0001] The utility model belongs to the technical field of hydrogen-rich water, and in particular relates to a water and gas mixing device. Background Art
[0002] Water-gas mixing is the mixing of water with a certain type of gas, such as oxygen, ozone, hydrogen, etc.; water-gas mixing will form micro-nano bubbles in the water. Water-gas mixing is generally achieved by pressurizing the gas and water to mix the gas with the liquid.
[0003] A Chinese patent document with publication number CN107459156B discloses a micro-nano bubble generating device and a water flow purification system, comprising a shell, in which a vortex-nano pump is arranged; the vortex-nano pump sucks water flow and air and preliminarily mixes them to obtain a primary water-gas mixture, and then transports the primary water-gas mixture to a water vapor vortex cutter, and then to a diverter; the water vapor vortex cutter is used to spirally mix the water-gas mixture generated by the vortex-nano pump; the diverter is used to disperse the primary water-gas mixture into a gas-water mixing accumulator; the gas-water mixing accumulator is used to further mix the primary water-gas mixture and then transport it to a micro-nano aeration nozzle; the micro-nano aeration nozzle is used to spray the high-pressure water-gas mixture into micro-nano-level water-gas liquid; the vortex-nano pump comprises a pump body and a motor, at least one side of the lower part of the pump body is provided with a water inlet port, the upper end of the pump body is provided with a water outlet port, the pump body is provided with an impeller assembly, and the motor is installed at the lower end of the pump body. The motor shaft extends into the pump body and drives the impeller assembly, which can transport the fluid from the water inlet port to the water outlet port. An air inlet port is provided on the pump body on one side of the water inlet port, and the inner ends of the air inlet port and the water inlet port are both connected to the inner cavity of the pump body; an inlet pipe is installed at the water inlet port, and a filter device is connected to the outer end of the inlet pipe, and a water inlet hole for filtering the fluid is provided on the filter device; the water vapor vortex cutter further spirally divides the primary water-gas mixture generated by the vortex nano pump; the gas-water mixing accumulator includes an upright gas-water mixing cylinder, and a plurality of inclined sieve plates are provided at the upper end of the mixing cylinder, and an accumulator water inlet connected to the diverter pipe is provided at the upper end of the sieve plate; 3 / 5 of the space in the upper part of the mixing cylinder is occupied by air, and when gas and water enter the gas-water mixing accumulator, the water is in a jetting state, and the water in the jetting state hits the wall of the gas-water mixing accumulator to become a waterfall, and falls in nearly 3 / 5 of the space, and the gas and water are further mixed to become a gas-water mixture and store energy. By rationally proportioning each functional component, the function of each component is fully utilized, thereby reducing unnecessary components and reducing production costs. The vortex nano pump 1 can inhale and preliminarily mix water and air to obtain a primary water-gas mixture. The gas-water mixing accumulator 4 can further mix the primary mixture and further increase the mixing ratio. The micro-nano aeration nozzle 5 can process the gas into micro-nano bubbles, and such a mixture can further increase the effect of sewage removal when it enters the sewage.
[0004] In the technical solution of the above patent document, the device for increasing the oxygen content in water is realized by continuously impacting the vortex cutting rod. The impact and cutting of the water flow by the vortex cutting rod does not actually change the direction of the water flow. If the direction of the water flow is not changed, part of the water flow will not impact the vortex cutting rod, resulting in a relatively poor water-gas mixing effect. In addition, the structure of the above patent technical solution is relatively complex and the cost is high. Utility Model Content

[0024] In one embodiment of the water and gas mixing device of the utility model, please refer to Figure 1 to Figure 4; The water and gas mixing device of this embodiment is used for mixing hydrogen and water. Specifically, it includes a mixing tank body 100 and an inner sleeve 200. A mixing chamber is provided inside the mixing tank body 100, and an input port 101 and an output port 102 are respectively provided at both ends of the mixing chamber. The inner sleeve 200 is arranged in the mixing chamber, and an annular water flow channel 201 is formed between the outer wall of the inner sleeve 200 and the inner wall of the mixing chamber. An air inlet pipe 210 is provided at the top end of the inner sleeve 200, and the air inlet pipe 210 extends into the input port 101, and a connecting portion 211 is provided between the outer wall of the air inlet pipe 210 and the inner wall of the input port 101, so that the inner sleeve 200 is fixed in the mixing tank body 100. In this embodiment, the input water pipe can be connected to the input port 101, and the air pipe for transporting hydrogen is connected to the air inlet pipe 210; therefore, water can be injected into the water flow channel 201 through the input water pipe, and hydrogen can be injected into the inner sleeve 200 through the air pipe for transporting hydrogen at the same time; therefore, in the process of water being transported from the water flow channel 201 to the output port position, an annular water flow surrounding the hydrogen is formed, and when the water flow is output from the mouth position of the water flow channel 201, the water flow is mixed in the form of wrapping the hydrogen; the mixing degree of hydrogen and water can be improved, thereby increasing the hydrogen content in the water.
[0025] For further information, please refer to Figure 1 to Figure 4 The mixing tank body 100 includes a head 110 and a tail 120, and both the head 110 and the tail 120 are conical structures, so that the water flow channel 201 is also a conical structure. When the water flow is transported in the water flow channel 201, the diameter of the annular water flow will gradually decrease, and the pressure of the water flow will gradually increase. Therefore, the effect of the water flow locking the hydrogen is more obvious. More specifically, the large end of the head 110 is connected to the large end of the tail 120, the input port 101 is arranged at the small end of the head 110, and the output port 102 is arranged at the small end of the tail 120.
[0026] For further information, please refer to Figure 1 to Figure 4 The output port 102 is extended with an output pipe 130, and the output pipe 130 is used to connect a water pipe, so as to conveniently output the hydrogen-mixed water to the water receiving position.
[0027] For further information, please refer to Figure 1 to Figure 4The output pipe 130 is provided with a spiral shaft 140, the outer diameter of the spiral shaft 140 is consistent with the inner diameter of the output pipe 130, and the outer surface of the spiral shaft 140 is provided with a spiral groove 141. The spiral shaft 140 is clamped in the output pipe 130, and the spiral shaft 140 and the inner wall of the output pipe 130 form a spiral flow channel. Specifically, when the water flow and gas enter the output pipe 140, they will hit the side wall of the spiral groove 141 of the spiral shaft 140 and be transported along the spiral groove 141. When the water flow and gas are transported in the spiral groove 141, the direction of the water flow will be constantly changed, and the water flow and the side wall of the spiral groove 141 will be mutually collided, so that the water is cut into a number of independent water molecules. After the water flow hits, the water molecules will recombine again. During the process of combining, the gas will be wrapped in the water, thereby achieving water-gas mixing.
[0028] For further information, please refer to Figure 1 to Figure 4 The output tube 130 is provided with a step 103, the end surface of the step 103 is provided with a slot 104, and one side of the spiral shaft 140 is provided with a key 142, and the key 142 is clamped in the slot 104. The spiral shaft 140 is fixed in the output tube 130.
[0029] Furthermore, the key 142 is inserted into the slot 104, and the end of the key 142 abuts against the end surface of the slot 104, so that a gap is formed between the end of the spiral shaft 140 and the outlet 102. Therefore, the mixed water can smoothly enter the spiral groove 140, avoiding the end surface of the spiral shaft 140 from causing excessive obstruction to the water flow.
[0030] For further information, please refer to Figure 1 to Figure 4 The outer end of the spiral shaft 140 is flush with the end surface of the output pipe 130, and a support portion 143 is further provided on the side of the spiral shaft 140 close to the outer end, and the support portion 143 supports the inner wall of the output pipe 130. In this embodiment, when the output pipe 130 is connected to the water pipe, the spiral shaft 140 can be limited by the step surface inside the water pipe to prevent the spiral shaft 140 from axial movement in the output pipe 130.
[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
