Description

Technical Field

[0001] This utility model relates to the technical field of water replenishment devices for water electrolysis hydrogen production equipment, and particularly to water replenishment devices for water electrolysis hydrogen production equipment. Background Technology

[0002] Hydrogen production equipment using water electrolysis generates hydrogen and oxygen during operation, while also consuming electrolyte. To maintain stable electrolyte concentration and conductivity, a water replenishment device is needed to periodically replenish water to the electrolytic cell.

[0003] Staff often find that the water replenishment device used in current water electrolysis hydrogen production equipment does not include a filtration function. When impurities in the water enter the electrolysis cell, they will deposit inside the cell, forming a film that hinders the contact between the electrodes and the electrolyte, thus reducing the electrolysis efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water replenishment device for hydrogen production equipment via water electrolysis.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water replenishment device for a water electrolysis hydrogen production equipment, comprising an electrolytic cell, a water replenishment pipe fixedly connected to the electrolytic cell, a water storage tank fixedly connected to the water replenishment pipe, a cover hinged to the water storage tank, a filter structure provided on the water storage tank, the filter structure mainly consisting of a filter cylinder, the filter cylinder being disposed in the water storage tank, a placement groove being provided on the filter cylinder, and a cover plate being provided on the placement groove.

[0006] The effect achieved by the above components is as follows: when the filter cartridge is installed in the water storage tank, water is injected into the hollow part in the middle of the filter cartridge when water is added to the water storage tank. The filter holes on the filter cartridge can filter out larger impurities. The filter element placed in the placement tank can further filter the water and facilitate the replacement of the filter element. The water flows to the outside of the filter cartridge after filtration and then flows into the electrolytic cell through the water supply pipe. This avoids the situation where impurities in the water enter the electrolytic cell and deposit inside the electrolytic cell, forming a film layer, which hinders the contact between the electrode and the electrolyte and thus reduces the electrolysis efficiency, because the current water supply device usually does not include a filtration function.

[0007] Preferably, the inner bottom wall of the water storage tank is provided with several connecting grooves, and several connecting rods are fixedly connected to the filter cylinder.

[0008] The effect achieved by the above components is that by inserting several connecting rods into the corresponding connecting slots, the filter cartridge can be quickly installed and disassembled, and the filter cartridge can be easily cleaned.

[0009] Preferably, three round rods are fixedly connected to the cover plate, and round rods are provided with round grooves. A sliding rod is slidably connected in the round grooves, and three round holes are provided on the inner wall of the water storage tank.

[0010] The effect achieved by the above components is as follows: the cover plate is locked in the placement groove, and the three sliding rods are slid so that the sliding rods are locked into the corresponding round holes, which makes the position of the filter cylinder more stable. When the cover plate needs to be removed, simply push the sliding rods inward through the round holes from the outside of the water storage tank so that they slide into the round groove.

[0011] Preferably, a first spring is fixedly connected to the inner wall of the circular groove, and one end of the first spring is fixedly connected to the slide rod.

[0012] The effect achieved by the above components is that when the slide rod is in the circular groove, it will compress the first spring into a contracted state. Therefore, when the slide rod comes into contact with the circular hole, the slide rod will be inserted into the circular hole under the action of the spring rebound force of the first spring, making the installation operation more convenient.

[0013] Preferably, the electrolytic cell is provided with a water replenishment structure, which is mainly composed of a sliding column. The sliding column is slidably inserted into the electrolytic cell, and a pipe plug is fixedly connected to the sliding column.

[0014] The effect achieved by the above components is as follows: sliding the sliding column upwards allows the pipe plug to be inserted into the water supply pipe, blocking the water supply pipe. When water needs to be replenished, simply slide the sliding column downwards to move the pipe plug away from the water supply pipe.

[0015] Preferably, an electromagnetic block is fixedly connected to the electrolytic cell, a fixing block is fixedly connected to the sliding column, and a metal block is fixedly connected to the fixing block.

[0016] The effect achieved by the above components is as follows: when water needs to be injected, the electromagnetic block can be energized, and the electromagnetic block will generate magnetism, which will attract the metal block and drive the fixed block to slide down, making the operation more convenient.

[0017] Preferably, a second spring is fixedly connected to the fixing block, and one end of the second spring is fixedly connected to the electrolytic cell.

[0018] The effect achieved by the above components is as follows: when the sliding column slides down, it will compress the second spring to contract. Therefore, after the water is filled, the power to the electromagnetic block is cut off, causing it to lose its magnetism. The fixed block then slides upward under the action of the rebound force of the second spring, further improving the convenience of operation.

[0019] Preferably, a lower liquid level sensor is fixedly connected to the electrolytic cell, and an upper liquid level sensor is fixedly connected to the electrolytic cell.

[0020] The effect achieved by the above components is as follows: when the liquid level in the electrolytic cell is lower than the lower liquid level sensor, the lower liquid level sensor will collect a signal and feed it back to the controller. The controller will then control the electromagnetic block to be energized. When the liquid level in the electrolytic cell is higher than the upper liquid level sensor, the upper liquid level sensor will collect a signal and feed it back to the controller. The controller will then control the electromagnetic block to be de-energized. Water can be automatically replenished without the need for staff to constantly monitor the liquid level in the electrolytic cell.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a filtration structure, the filter cartridge is installed in a water storage tank. When water is added to the storage tank, water is injected into the hollow part of the filter cartridge. The filter holes on the filter cartridge can filter larger impurities. Placing the filter element in the placement slot further filters the water and facilitates filter element replacement. Water flows through the filter to the outside of the filter cartridge and then flows into the electrolysis cell through the water supply pipe. Inserting several connecting rods into the corresponding connecting slots allows for quick installation and disassembly of the filter cartridge, facilitating cleaning. The cover plate is secured in the placement slot, and three... The sliding rod engages with the corresponding circular hole, making the filter cartridge more stable. When the cover needs to be removed, simply push the sliding rod inward through the circular hole from the outside of the water tank, allowing it to slide into the circular groove. When the sliding rod is in the circular groove, it compresses the first spring, putting it in a contracted state. Therefore, when the sliding rod contacts the circular hole, it engages with the circular hole under the rebound force of the first spring, making installation and operation more convenient. This avoids the situation where impurities in the water, which usually do not include filtration, deposit in the electrolytic cell after entering the electrolytic cell, forming a film layer that hinders the contact between the electrode and the electrolyte, thus reducing electrolysis efficiency.

[0027] Example 1, as Figure 1 As shown, the water replenishment device for the water electrolysis hydrogen production equipment includes an electrolytic cell 1, a water replenishment pipe 3 fixedly connected to the electrolytic cell 1, a water storage tank 2 fixedly connected to the water replenishment pipe 3, and a cover 4 hinged to the water storage tank 2.

[0028] Reference Figures 1 to 3 The water storage tank 2 is equipped with a filter structure 5, which mainly consists of a filter cylinder 51. The filter cylinder 51 is placed in the water storage tank 2 and has a placement groove 52. The placement groove 52 is covered with a cover plate 53. When the filter cylinder 51 is installed in the water storage tank 2, water is injected into the hollow part in the middle of the filter cylinder 51. The filter holes on the filter cylinder 51 can filter out larger impurities. Placing a filter element in the placement groove 52 can further filter the water and facilitate the replacement of the filter element. Water flows through the filter to the outside of the filter cylinder 51, and then flows into the electrolytic cell 1 through the water supply pipe 3. This avoids the situation where impurities in the water, which usually do not include filtration, deposit in the electrolytic cell 1, forming a film that hinders the contact between the electrodes and the electrolyte, thus reducing electrolysis efficiency. Several connecting grooves 55 are provided on the inner bottom wall of the water storage tank 2, and several connecting rods 54 are fixedly connected to the filter cylinder 51. The connecting rods 54 are inserted into their corresponding... The filter cartridge 51 can be quickly installed and removed in the connecting groove 55, facilitating cleaning. Three round rods 56 are fixedly connected to the cover plate 53. Round rods 56 have round grooves 57, and sliding rods 58 are slidably connected in the grooves 57. Three round holes 59 are provided on the inner wall of the water storage tank 2. By securing the cover plate 53 to the placement groove 52 and sliding the three sliding rods 58, the rods 58 are engaged in the corresponding round holes 59, ensuring a more stable position for the filter cartridge 51. When the cover plate 53 needs to be removed... Simply push the slide rod 58 inward through the round hole 59 from the outside of the water tank 2, so that it slides into the round groove 57. A first spring 510 is fixedly connected to the inner wall of the round groove 57. One end of the first spring 510 is fixedly connected to the slide rod 58. When the slide rod 58 is in the round groove 57, it will compress the first spring 510 and put it in a contracted state. Therefore, when the slide rod 58 contacts the round hole 59, the slide rod 58 will be inserted into the round hole 59 under the action of the spring force of the first spring 510, making the installation operation more convenient.

[0029] Reference Figure 2 and Figure 4 The electrolytic cell 1 is equipped with a water replenishment structure 6, which mainly consists of a sliding column 61. The sliding column 61 is slidably inserted into the electrolytic cell 1, and a pipe plug 62 is fixedly connected to the sliding column 61. Sliding the sliding column 61 upwards allows the pipe plug 62 to be inserted into the water replenishment pipe 3, blocking the water replenishment pipe 3. When water needs to be replenished, simply slide the sliding column 61 downwards to move the pipe plug 62 away from the water replenishment pipe 3. An electromagnetic block 64 is fixedly connected to the electrolytic cell 1, and a fixing block 63 is fixedly connected to the sliding column 61. A metal block 65 is fixedly connected to the fixing block 63. When water needs to be added, the electromagnetic block 64 can be energized, and the electromagnetic block 64 will generate magnetism, thereby attracting the metal block 65 and causing the fixing block 63 to slide down, making the operation more convenient. A second spring 66 is fixedly connected to the fixing block 63, and one end of the second spring 66 is fixedly connected to... Connected to the electrolytic cell 1, when the sliding column 61 slides down, it will compress the second spring 66 to contract. Therefore, after the water is filled, the power to the electromagnetic block 64 is turned off, causing it to lose its magnetism. The fixed block 63 then slides upward under the action of the rebound force of the second spring 66, further improving the convenience of operation. A lower liquid level sensor 67 and an upper liquid level sensor 68 are fixedly connected in the electrolytic cell 1. When the liquid level in the electrolytic cell 1 is lower than that of the lower liquid level sensor 67, the lower liquid level sensor 67 will send a signal to the controller, which will then control the electromagnetic block 64 to be energized. When the liquid level in the electrolytic cell 1 is higher than that of the upper liquid level sensor 68, the upper liquid level sensor 68 will send a signal to the controller, which will then control the electromagnetic block 64 to be de-energized. This allows for automatic water replenishment without the need for staff to constantly monitor the liquid level in the electrolytic cell 1.

[0030] Working principle: The filter cartridge 51 is installed in the water storage tank 2. When water is added to the water storage tank 2, water is injected into the hollow part of the filter cartridge 51. The filter holes on the filter cartridge 51 can filter out larger impurities. Placing a filter element in the placement slot 52 can further filter the water and facilitate filter element replacement. The water flows to the outside of the filter cartridge 51 after filtration, and then flows into the electrolytic cell 1 through the water supply pipe 3. This avoids the situation where impurities in the water, which usually do not include filtration function, enter the electrolytic cell 1 and deposit there, forming a film layer that hinders the contact between the electrode and the electrolyte, thus preventing... To reduce electrolysis efficiency, several connecting rods 54 are inserted into corresponding connecting slots 55, allowing for quick installation and removal of the filter cartridge 51 and facilitating cleaning. The cover plate 53 is secured to the placement slot 52, and the three sliding rods 58 are slid into their corresponding round holes 59, making the filter cartridge 51 more stable. To remove the cover plate 53, simply push the sliding rod 58 inward through the round hole 59 from the outside of the water tank 2, causing it to slide into the round groove 57. When the sliding rod 58 is in the round groove 57, it compresses the first spring 510, putting it in a contracted state. Therefore, when... When the sliding rod 58 contacts the round hole 59, it is engaged in the round hole 59 under the elastic force of the first spring 510, making installation easier. Sliding the sliding column 61 upwards allows the pipe plug 62 to be inserted into the water supply pipe 3, blocking it. When water needs to be added, simply slide the sliding column 61 downwards, moving the pipe plug 62 away from the water supply pipe 3. When water needs to be added, the electromagnetic block 64 can be energized, generating magnetism that attracts the metal block 65, causing the fixing block 63 to slide down, making operation more convenient. As the sliding column 61 slides down, it compresses the second spring 66, causing it to contract. After water filling is completed, the electromagnetic block 64 is de-energized, causing it to lose its magnetism. The fixed block 63 then slides upward under the elastic force of the second spring 66, further improving the ease of operation. When the liquid level in the electrolytic cell 1 is lower than the lower liquid level sensor 67, the lower liquid level sensor 67 will send a signal to the controller, which will then energize the electromagnetic block 64. When the liquid level in the electrolytic cell 1 is higher than the upper liquid level sensor 68, the upper liquid level sensor 68 will send a signal to the controller, which will then de-energize the electromagnetic block 64. This allows for automatic water replenishment without requiring staff to constantly monitor the liquid level in the electrolytic cell 1.
