Description

Technical Field

[0001] This utility model relates to the field of hydrogen-rich water preparation technology, specifically to a hydrogen-rich water preparation device. Background Technology

[0002] Hydrogen-rich water, also known as "hydrogen water", is essentially water in which trace amounts of hydrogen gas are dissolved.

[0003] Chinese Patent No. CN117303547A discloses a hydrogen-rich water preparation device, including a hydrogen production component, a by-product treatment component, a hydrogen-rich water preparation component, and a control component. The hydrogen production component includes a storage component, a water supply component, and a reaction chamber component. The storage component stores the hydrolysis hydrogen-producing materials, and the reaction chamber component is connected to both the storage component and the water supply component. The by-product treatment component is connected to the reaction chamber component. The hydrogen-rich water preparation component is connected to the hydrogen outlet of the reaction chamber component. The control component is connected to the hydrogen production component, the hydrogen-rich water preparation component, and the by-product treatment component. The hydrogen-rich water preparation device provided in this application connects the by-product treatment component to the reaction chamber component. After the hydrogen inside the reaction chamber component is output through the hydrogen outlet, the residual wastewater, water-insoluble aluminum hydroxide colloidal precipitate, and unreacted waste inside the reaction chamber component can all be collected and treated in the by-product treatment component.

[0004] When in use, the device produces hydrogen by reacting the hydrogen-producing material with the reaction water. However, the output hydrogen contains some water vapor and impurities from the reaction water, which reduces the purity of the hydrogen and thus affects the quality of the hydrogen-rich water.

Detailed Implementation

[0022] The following will be for reference. Figures 1 to 5 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0023] A hydrogen-rich water preparation device, such as Figures 1-3 As shown, the system includes a reaction vessel 1, a filter plate 2 inside the reaction vessel 1, and a filter pad 3 on top of the filter plate 2. The filter pad 3 is made of nano-sponge. A cylinder 5 is installed on top of the reaction vessel 1, with its free end extending into the reaction vessel 1 and a connecting block 6 at its end. A pressure plate 8 is installed above the filter pad 3, and a spring 7 is installed between the connecting block 6 and the pressure plate 8. A limiting mechanism is provided on the pressure plate 8, and a limiting groove 9 is opened on the inner wall of the reaction vessel 1. The limiting part of the limiting mechanism is fitted into the limiting groove 9. After the hydrolysis hydrogen-producing material reacts with the reaction water in the reaction vessel 1, hydrogen gas and impurities (such as aluminum hydroxide gel) are produced. The hydrogen gas rises and is discharged from the gas outlet pipe at the top of the reaction vessel 1 to the subsequent hydrogen dissolving equipment. It should be noted that during the rising process of the hydrogen gas, a certain amount of water vapor and impurities from the reaction water will be mixed in, resulting in a low purity of hydrogen gas. The filter pad 3 can improve the purity of hydrogen gas, thereby ensuring the quality of hydrogen-rich water.

[0024] like Figure 3 and Figure 5 As shown, the limiting mechanism includes a blind hole 10 formed on the outer surface of the pressure plate 8. A limiting rod 11 is slidably fitted inside the blind hole 10. One end of the limiting rod 11 extends out of the blind hole 10 and is inserted into the inside of the limiting groove 9. An electric spring device 12 is installed between the limiting rod 11 and the bottom wall of the blind hole 10. When the electric spring device 12 is energized, the electric spring device 12 retracts and pulls the limiting rod 11 to retract into the blind hole 10.

[0025] like Figure 2As shown, the bottom of the connecting block 6 is provided with a drive rod 13, which passes through the pressure plate 8, filter pad 3 and filter plate 2 in sequence. The bottom of the outer surface of the drive rod 13 is provided with a ball bearing (not shown). The inner bottom wall of the reaction vessel 1 is rotatably connected to an internal threaded cylinder 14. The spiral groove of the internal threaded cylinder 14 slides with the ball bearing. The outer surface of the internal threaded cylinder 14 is provided with a fan blade 15. Through the cooperation between the ball bearing and the internal threaded cylinder 14, when the drive rod 13 moves up and down, it drives the internal threaded cylinder 14 to rotate in both directions. The fan blade 15 rotates in both directions and stirs the material in the reaction vessel 1 in both directions.

[0026] like Figure 3 As shown, the top of the filter plate 2 is provided with a guide key bar 16, and the pressure plate 8 is provided with a keyway that matches the guide key bar 16. The stability of the lifting and lowering movement of the pressure plate 8 is improved by the cooperation of the guide key bar 16 and the keyway.

[0027] like Figure 2 and Figure 4 As shown, a groove 17 is provided on the inner wall of the reaction vessel 1, and a slider 19 is slidably fitted on the groove 17. An annular plate 18 is provided at the bottom of the slider 19, and the annular plate 18 is located above the filter pad 3. The reaction vessel 1 is composed of a top end cap and a reaction cylinder. The top end cap and the reaction cylinder are detachably connected. In this embodiment, the top end cap and the reaction cylinder are connected by bolts. A protrusion 4 is provided on the inner wall of the top end cap, and the protrusion 4 is located above the slider 19.

[0028] When the device is in use, the cylinder 5 is activated to repeatedly extend and retract the free end of the cylinder 5. The connecting block 6 drives the drive rod 13 to move up and down continuously. It should be noted that in the initial state, the electric spring device 12 is de-energized, that is, the limit rod 11 is inserted into the limit groove 9. When the connecting block 6 moves up and down, the spring 7 moves in a contracting and expanding motion. At this time, the pressure plate 8 will not move.

[0029] When the drive rod 13 moves up and down, it drives the internal threaded cylinder 14 to rotate in both directions, and the fan blade 15 rotates in both directions to stir the material in the reaction vessel 1 in both directions, thereby improving the mixing efficiency of the hydrolysis hydrogen production material and the reaction water, that is, improving the hydrogen production efficiency.

[0030] By setting the filter pad 3, water vapor and impurities mixed in the hydrogen can be filtered. After the device has been working for a period of time, the electric spring device 12 is energized, the electric spring device 12 retracts and pulls the limit rod 11 to retract into the blind hole 10, thereby releasing the limit on the pressure plate 8. At this time, when the connecting block 6 rises and falls again, the pressure plate 8 rises and falls and repeatedly squeezes the filter pad 3 to squeeze out the water from the filter pad 3, so as to avoid the filter pad 3 having too much water content and affecting the filtration effect.

[0031] When the top end cap and the reaction cylinder are in a closed state, the protrusion 4 abuts against the slider 19, causing the annular plate 18 to press against the edge of the filter pad 3, thereby positioning the filter pad 3. When the filter pad 3 needs to be replaced, the top end cap is separated from the reaction cylinder, and the protrusion 4 no longer abuts against the slider 19. The slider 19 can slide along the groove 17 to move the annular plate 18 upward, thus facilitating the replacement of the filter pad 3.

[0032] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
