Description
Technical Field
[0001] This utility model belongs to the technical field of water electrolysis equipment, and specifically relates to a water electrolysis equipment for producing hydrogen and oxygen. Background Technology
[0002] Electrolytic water hydrogen and oxygen production equipment decomposes water molecules into hydrogen and oxygen through an electrolytic reaction. Due to the high purity of the products and the clean and pollution-free process, it is widely used in energy storage, medical oxygen supply, chemical synthesis and other fields. Its core principle is that under the action of direct current, water molecules undergo a reduction reaction at the cathode to produce hydrogen and an oxidation reaction at the anode to produce oxygen. The reaction process relies on a stable electrode structure, an efficient ion conduction medium and a reliable gas-liquid separation system.
[0003] The current announcement of Chinese utility model patent CN218710887U discloses an electrolysis water hydrogen production device, which is equipped with an electrolysis unit. The electrolysis unit includes an electrolysis tank, an anode, a proton exchange membrane, and a cathode. The anode, proton exchange membrane, and cathode are all located inside the electrolysis tank. The cathode has a cylindrical structure, while the anode and proton exchange membrane have cylindrical structures. The proton exchange membrane and anode are arranged sequentially around the outside of the cathode. This arrangement facilitates the storage and movement of the equipment, making the electrolysis water hydrogen production device more convenient to use.
[0004] The patent lacks a purification structure. During the electrolysis process, when the gas escapes from the electrolyte, it will carry a large number of electrolyte droplets, such as KOH droplets in alkaline electrolysis. At the same time, it will also mix in undecomposed water molecules. Relying solely on gravity sedimentation, it is difficult to completely separate the droplets and water vapor, resulting in excessive liquid impurities in the output gas. Utility Model Content
[0005] The purpose of this invention is to provide an electrolytic water hydrogen and oxygen production device, which solves the problem of existing electrolytic water hydrogen production devices lacking a purification structure. During the electrolysis process, when the gas escapes from the electrolyte, it carries a large number of electrolyte droplets and undecomposed water molecules. Relying solely on gravity sedimentation, the droplets and water vapor are difficult to separate completely, resulting in excessive liquid impurities in the output gas.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an electrolysis water hydrogen and oxygen production device, including an electrolysis tank, a sealing cover provided on the electrolysis tank, an anode and a cathode provided inside the electrolysis tank, a power connector provided on the anode and the cathode, a gathering mechanism provided on the anode and the cathode, a centrifugal purification mechanism provided on the gathering mechanism, and both the cathode and the anode having a conical spiral plate structure;
[0007] The focusing mechanism includes a focusing cover, a connecting cavity, and a conical cavity. The focusing cover is located inside the electrolysis tank. There are two focusing covers, which respectively cover the cathode and the anode. One end of the connecting cavity is fixedly connected to the focusing cover, and the other end of the conical cavity is fixedly connected to the connecting cavity. The conical cavity is fixedly connected to the sealing cover.
[0008] The above technical solution, by setting up an electrolysis tank, a sealing cover, an anode, a cathode, a power connector, a gathering mechanism, and a centrifugal purification mechanism, allows the sealing cover to seal the electrolysis tank during use, preventing the generated gas from escaping. Electrolyte is then added to the electrolysis tank, and the power connectors on the cathode and anode are connected to an external power source to electrolyze water. The cathode produces hydrogen, and the anode produces oxygen. The gathering mechanism collects the generated gas and directly transmits it to the centrifugal purification mechanism, where impurities are removed, increasing the concentration of the produced gas. The gathering mechanism includes a gathering hood, a connecting cavity, and a conical cavity. When gas is generated at the cathode and anode, it directly enters the gathering hood and is then connected to the centrifugal purification mechanism via the connecting cavity and the conical cavity, thus transporting the gas into the centrifugal purification mechanism.
[0009] Furthermore: the centrifugal purification mechanism includes a centrifuge hood, a centrifuge chamber, a connecting rod, a micro motor, a mounting groove, a through-hole, and a filter plate. The centrifuge hood is fixedly connected to the conical chamber, and the centrifuge chamber is rotatably disposed inside the centrifuge hood. The connecting rod is fixedly disposed on the centrifuge chamber, and the other end of the connecting rod extends to the outside of the centrifuge hood. The connecting rod and the centrifuge hood are rotatably connected through a sealed bearing. The micro motor is disposed on the connecting rod. The mounting groove is opened on the side wall of the centrifuge chamber, and the through-hole is opened on the mounting groove and penetrates the centrifuge chamber. The filter plate is fixedly disposed inside the mounting groove. The filter plate above the cathode is a palladium-silver membrane, and the filter plate above the anode is a molecular sieve membrane.
[0010] Using the above technical solution, by setting up a centrifuge hood, centrifuge chamber, connecting rod, micro motor, mounting slot, through port, and filter plate, after the gas is transported to the centrifuge chamber, the micro motor is turned on. The micro motor drives the centrifuge chamber to rotate through the connecting rod. Then, the rotation of the centrifuge chamber causes the gas to rotate, resulting in centrifugal force. The gas impacts the side wall of the centrifuge chamber, and the liquid in the gas flows back into the electrolysis tank along the side wall of the centrifuge chamber. The mounting slot can install the filter plate to filter the gas. The palladium-silver membrane only allows hydrogen to pass through, and the molecular sieve membrane can prevent water molecules from passing through, thus achieving gas purification.
[0011] Furthermore: a hydrogen collection bottle is provided on one side of the electrolysis tank, and an oxygen collection bottle is provided on the other side of the electrolysis tank. Fixing frames are provided on the hydrogen collection bottle and the oxygen collection bottle. The hydrogen collection bottle is located on the side closer to the cathode, and the oxygen collection bottle is located on the side closer to the anode.
[0012] Using the above technical solution, by setting up a hydrogen collection bottle, an oxygen collection bottle, and a fixing frame, the two fixing frames respectively fix the hydrogen collection bottle and the oxygen collection bottle during use. Then, the purified hydrogen enters the hydrogen collection bottle, and the purified oxygen enters the oxygen collection bottle.
[0013] Furthermore: the centrifuge hood above the cathode is connected to a hydrogen collection bottle via a first connecting pipe, and the centrifuge hood above the anode is connected to an oxygen collection bottle via a second connecting pipe. A delivery pump is installed on the first connecting pipe and the second connecting pipe.
[0014] By adopting the above technical solution, and by setting up a first connecting pipe, a second connecting pipe, and a delivery pump, the first connecting pipe can deliver hydrogen, the second connecting pipe can deliver oxygen, and the delivery pump can adjust the gas delivery rate.
[0015] Furthermore: a limiting groove is provided on the side wall of the centrifuge shroud, and a limiting ring is provided on the side wall of the centrifuge chamber. The limiting ring is rotatably connected in the limiting groove, and the contact surface between the limiting groove and the limiting ring is smoothly provided.
[0016] By adopting the above technical solution, and by setting a limiting groove and a limiting ring, when the centrifuge chamber rotates, the limiting ring can rotate in the limiting groove. Through the cooperation of the limiting ring and the limiting groove, the rotation of the centrifuge chamber can be limited, so that the centrifuge chamber can be stably limited.
[0017] Furthermore: the electrolysis tank is provided with an observation window, which is made of transparent material, and a scale line is provided on one side of the observation window.
[0018] By adopting the above technical solution, and by setting up an observation window and scale lines, the observation window allows for observation of the water level inside the electrolysis tank during use, and the scale lines provide an intuitive sense of the water level.
[0019] Furthermore: a sealing groove is provided at the upper end of the electrolysis tank, and a sealing gasket is provided on the sealing cover, with the sealing gasket corresponding to the sealing groove.
[0020] By adopting the above technical solution, by setting a sealing groove and a sealing gasket, when the sealing cover is on the electrolysis tank, the sealing gasket enters the sealing groove and is squeezed by the sealing groove, thereby making the sealing cover and the electrolysis tank completely sealed.
[0021] Furthermore: a water inlet pipe is fixedly installed on the sealing cover, the water inlet pipe extends into the interior of the electrolysis tank, and a sealing plug is installed on the water inlet pipe.
[0022] By adopting the above technical solution, and by setting up a water inlet pipe and a sealing plug, the water inlet pipe can easily add electrolyzed water into the electrolysis tank during use, and the sealing plug can seal the water inlet pipe to prevent gas from escaping.
[0023] In summary, this utility model has the following beneficial effects:
[0024] By setting up a gathering mechanism, when the cathode and anode generate gas, the gas directly enters the gathering hood, and then is connected to the centrifugal purification mechanism through the connecting cavity and the conical cavity, so that the gas is transported into the centrifugal purification mechanism.
[0025] By setting up a centrifugal purification mechanism, after the gas is transported to the centrifuge chamber, the micro motor is turned on. The micro motor drives the centrifuge chamber to rotate through the connecting rod. Then, the rotation of the centrifuge chamber causes the gas to rotate, resulting in centrifugal force. The gas impacts the side wall of the centrifuge chamber, and the liquid in the gas flows back into the electrolysis tank along the side wall of the centrifuge chamber. The installation slot can install the filter plate to filter the gas. The palladium-silver membrane only allows hydrogen to pass through, and the molecular sieve membrane can prevent water molecules from passing through, thus achieving gas purification.
[0026] Based on the above improvements, the overall technical effect achieved by this device is that it can collect the generated hydrogen and oxygen separately through a gathering mechanism, and then purify the generated hydrogen and oxygen through a centrifugal purification mechanism, so that the resulting gas has higher purity.

One end of the connecting cavity 602 is fixedly connected to the focusing cover 601, and the conical cavity 603 is fixedly connected to the other end of the connecting cavity 602. The conical cavity 603 is fixedly connected to the sealing cover 2.
[0038] By setting up an electrolysis tank 1, a sealing cover 2, an anode 3, a cathode 4, a power connector 5, a gathering mechanism 6, and a centrifugal purification mechanism 7, the sealing cover 2 can seal the electrolysis tank 1 during use to prevent the generated gas from escaping. Then, an electrolyte is added to the electrolysis tank 1, and the power connectors 5 on the cathode 4 and anode 3 are connected to an external power source to electrolyze the water. The cathode 4 produces hydrogen gas, and the anode 3 produces oxygen gas. The gathering mechanism 6 can then collect the generated gas and directly transmit it to the centrifugal purification mechanism 7. The centrifugal purification mechanism 7 removes impurities from the gas to increase the concentration of the produced gas. The gathering mechanism 6 includes a gathering cover 601, a connecting cavity 602, and a conical cavity 603. When the cathode 4 and anode 3 generate gas, the gas directly enters the gathering cover 601, and then is connected to the centrifugal purification mechanism 7 through the connecting cavity 602 and the conical cavity 603 to transport the gas into the centrifugal purification mechanism 7.

The micro motor 704 is then turned on, and the micro motor 704 drives the centrifuge chamber 702 to rotate via the connecting rod 703. The rotation of the centrifuge chamber 702 causes the gas to rotate, generating centrifugal force. This causes the gas to impact the side wall of the centrifuge chamber 702, and the liquid carried in the gas flows back into the electrolysis tank 1 along the side wall of the centrifuge chamber 702. The mounting slot 705 allows the filter plate 707 to be installed, enabling gas filtration.

Then, the sealing plug 20 can seal the water inlet pipe 19 to prevent gas from escaping.
[0047] Brief description of usage:
[0048] In use, the sealing cover 2 first seals the electrolysis tank 1 to prevent the gas from escaping. Then, the electrolytic liquid is added to the electrolysis tank 1. The power connectors 5 on the cathode 4 and anode 3 are connected to an external power source to electrolyze the water. The cathode 4 produces hydrogen gas, and the anode 3 produces oxygen gas. The water inlet pipe 19 facilitates the addition of electrolyzed water to the electrolysis tank 1. Then, the sealing plug 20 seals the water inlet pipe 19 to prevent the gas from escaping.

Through the limiting ring 14 and the limiting groove 13 The combined action of the centrifuge chamber 702 can limit the rotation of the centrifuge chamber 702, so that the centrifuge chamber 702 can be stably limited. Then, the rotation of the centrifuge chamber 702 drives the gas to rotate and generate centrifugal force, so that the gas impacts the side wall of the centrifuge chamber 702. The liquid in the gas flows back into the electrolysis tank 1 along the side wall of the centrifuge chamber 702. The mounting slot 705 can install the filter plate 707 to filter the gas. The palladium-silver membrane only allows hydrogen to pass through, and the molecular sieve membrane can prevent water molecules from passing through, thereby purifying the gas.
[0050] Finally, the two fixing brackets 10 fix the hydrogen collection bottle 8 and the oxygen collection bottle 9 respectively. Then, the purified hydrogen enters the hydrogen collection bottle 8 and the purified oxygen enters the oxygen collection bottle 9. The first connecting pipe 11 can transport hydrogen and the second connecting pipe 12 can transport oxygen. The delivery pump can adjust the gas delivery rate. The observation window 15 can observe the water level inside the electrolysis tank 1. The scale line 16 can provide a direct sense of the water level. When the sealing cap 2 is on the electrolysis tank 1, the sealing gasket 18 enters the sealing groove 17 and is squeezed by the sealing groove 17, thereby making the sealing cap 2 and the electrolysis tank 1 completely sealed.
