Description
Technical Field
[0001] The present invention relates to the technical field of electrolytic cells, and specifically to a rotating electrolytic cell with an internal hydrogen storage tank. Background Art
[0002] An electrolytic cell is a device used for electrolysis, which consists of a cell body, an anode, and a cathode. Most of them use a diaphragm to separate the anode chamber and the cathode chamber. It is widely used in many fields such as metal smelting, chemical synthesis, electroplating process, etc. By applying an external potential, the ions in the electrolyte solution undergo oxidation-reduction reactions to produce the required chemical substances. Among them, a rotating electrolytic cell is an electrolytic cell that promotes the electrolysis reaction by rotating the electrode. Its characteristic is that at least one electrode (usually the cathode) can rotate. This design can optimize the ion transport and bubble separation during the electrolysis process, thereby improving the electrolysis efficiency.
[0003] For example, the Chinese patent application with the publication number CN116815216A discloses a rotating electrolytic cell with an internal hydrogen storage tank, including: the top of the rotating electrolytic cell body is a water tank, and the water tank is connected to the reaction chamber through a one-way water guiding valve of the water tank. A number of partitions are arranged in the reaction chamber from top to bottom in sequence. The upper surface of each partition is provided with a positive electrode plate, and the lower surface of each partition is provided with a negative electrode plate. A slip ring is arranged in the conductive slip ring housing, and the slip ring is electrically connected to the positive electrode plate and the negative electrode plate to supply power to them; the reaction chamber is connected to the hydrogen storage tank through a one-way valve.
[0004] However, there are still some problems in the above patent. After the rotating electrolytic cell works for a period of time in the above patent, when the gas in the hydrogen storage tank reaches the maximum capacity, the hydrogen storage tank needs to be disassembled to replace it. During this process, the operator has to either stop the electrolysis work or continue the electrolysis. And there will be a large energy loss at the moment of starting and stopping the device. Therefore, it is generally not recommended to continuously start and stop the device. If the electrolysis continues, it will cause the pressure in the reaction chamber of the rotating electrolytic cell to increase, which is likely to cause damage to the rotating electrolytic cell.
[0005] Therefore, how to temporarily store the hydrogen exceeding the capacity of the hydrogen storage tank during the hydrogen generation process is a problem to be solved currently. Summary of the Invention

[0053] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0055] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0056] The present invention discloses a rotating electrolyzer with a built-in hydrogen storage tank, referring to Figures 1-9 ,include:
[0057] A rotating electrolytic cell 1 body is used to electrolyze the electrolyte placed in the electrolytic cell and generate corresponding gases; a collection device 3 is connected to the rotating electrolytic cell 1 through a first connecting pipe and is used to collect the gases generated by the electrolytic cell; a liquid injection device 4 is arranged at the top of the rotating electrolytic cell 1 body and is used to clamp the output end of the pipeline for transporting the electrolyte and isolate it from the outer wall of the rotating electrolytic cell 1 body; the collection device 3 includes a flow splitting unit 31, a gas storage tank 32, a second connecting pipe 33, a transfer unit 34 and a temporary storage tank 35; the flow splitting unit 31 is respectively connected to the gas storage tank 32, the second connecting pipe 33 and the first connecting pipe, changes the flow direction of the gas, and enables the gas to enter the gas storage tank 32 or enter the second connecting pipe 33; the transfer unit 34 is preset with a set prestress. When the pressure in the second connecting pipe 33 exceeds the set prestress, where the set prestress is determined by those skilled in the art according to specific application requirements, the gas passes through the transfer unit 34 and is collected by the temporary storage tank 35; the gas storage tank 32 can be built into the rotating electrolytic cell 1 or can be placed outside the rotating electrolytic cell 1. At the same time, through the arranged flow splitting unit 31, gas storage tank 32, second connecting pipe 33, transfer unit 34 and temporary storage tank 35, the flow direction of the gas in the support pipe 346 can be adjusted, so that it can enter the gas storage tank 32 or the temporary storage tank 35, and the gas storage work is completed. Through the arranged gas storage tank 32, the gases generated during electrolysis can be collected, avoiding damage to the rotating electrolytic cell 1 due to excessive air pressure in the reaction chamber of the electrolytic cell. By allowing the gas to flow into the temporary storage tank 35, the entire electrolysis process does not need to be stopped while replacing the new gas storage tank 32. The gases generated during the replacement process will cause an increase in the air pressure in the reaction chamber of the rotating electrolytic cell 1 according to the amount of gas generated. When it exceeds the preset pressure value, the gas can enter the temporary storage tank 35 along the transfer unit 34, which can not only collect the gas but also avoid damage to the device.
[0058] The shunt unit 31 includes a shunt valve 311 body, a communication cavity formed in the shunt valve 311 body, a first intake end 313, a first outlet end 312, and a second outlet end 314 respectively connected to the communication cavity, a shunt cylinder 315 provided on the shunt valve 311, a driving rod 316 connected to the output end of the shunt cylinder 315, a frustum-shaped pushing block 317 provided at one end of the driving rod 316 and located in the communication cavity, and a seal 318 connected to the pushing block 317. The communication cavity includes a first communication cavity and a second communication cavity, a partition plate provided between the first communication cavity and the second communication cavity, and a through hole formed in the partition plate. The first intake end 313 is connected to a first connecting pipe, the first outlet end 312 is communicated with a gas storage tank 32, and the second outlet end 314 is communicated with a second connecting pipe 33. When the gas storage tank 32 reaches its predetermined storage capacity, the shunt unit 31 starts to work at this time. The shunt cylinder 315 in the shunt unit 31 starts to work. The moving shunt cylinder 315 can drive the driving rod 316 to move, so as to adjust the movement of the pushing block 317 in the first communication cavity, so that the pushing block 317 can block the first outlet end 312. At this time, the gas moving from the original first intake end 313 to the first outlet end 312 changes to moving from the first intake end 313 to the second outlet end 314, and then can enter the second connecting pipe 33. By providing the shunt unit 31, the gas can move from the first connecting pipe into the gas storage tank 32, or through the movement of the shunt unit 31, the gas passes through the shunt valve 311 body and enters the second connecting pipe 33 and is transported to a temporary storage tank 35. During this process, the outlet end connected to the gas storage tank 32 is blocked, so that the gas storage tank 32 is in an independent state, so that the gas storage tank 32 can be replaced, and then the next gas storage work can be carried out.
[0059] In a further embodiment, the first communication cavity is respectively connected to the first intake end 313 and the first outlet end 312, and the second communication cavity is respectively communicated with the second outlet end 314 and the first communication cavity. The bottom diameter of the frustum-shaped pushing block 317 is larger than the diameter of the through hole, so that the pushing block 317 can only move in the first communication cavity, and the diameter of the seal 318 is greater than or equal to the diameter of the first outlet end 312. When the driving rod 316 pushes the seal 318 to move in the first communication cavity, the seal 318 can block the first outlet end 312, that is, move in the direction away from the shunt cylinder 315, changing the flow direction of the gas in the shunt valve 311, so that the gas can be transported into the second connecting pipe 33 or enter the temporary storage tank 35, enabling the replacement of the full gas storage tank 32 without stopping the electrolysis process, thus not interrupting the electrolysis process, and also avoiding the gas staying in the reaction chamber of the rotary electrolyzer 1 and preventing its pressure from being too high, which may cause damage to the rotary electrolyzer 1.
[0060] The transfer unit 34 includes a transfer sleeve 341 for connecting the second connecting pipe 33 and the temporary storage tank 35. An air duct for gas flow is provided in the transfer sleeve 341. An adjusting component 342 is arranged on one side of the transfer sleeve 341. A support pipe 346 is in contact with the inner wall of the air duct. A movable seat 343 is connected to the adjusting component 342 and is located in the support pipe 346. A plurality of special-shaped plates 345 are evenly arranged on the inner wall of the support pipe 346 and are movably connected to the support pipe 346. And a sealing block 347 is used for connecting the special-shaped plates 345. Wherein a contact spring 344 is further arranged between the movable seat 343 and the special-shaped plate 345. The air duct is of a T-shaped structure. The adjusting component 342 is located at the shoulder of the air duct. The other shoulder of the air duct is communicated with the second connecting pipe 33. The vertical direction of the air duct is communicated with the temporary storage tank 35. By changing the position of the sealing block 347 in the air duct, the flow direction of the gas is changed, and the storage work of the gas is completed. When the gas enters the second connecting pipe 33, at this time, the operator can replace the gas storage tank 32. During this process, the electrolysis speed is not affected. At the same time, if the installation work of the gas storage tank 32 is completed before the air pressure in the second connecting pipe 33 reaches the preset air pressure, the gas can move from the first air inlet end 313 to the first air outlet end 312 and enter the gas storage tank 32 through the work of the shunt cylinder 315. On the contrary, the gas exceeding the preset air pressure can make the sealing block 347 move towards the movable seat 343 direction, so that the gas can move along the transfer sleeve 341 to the temporary storage tank 35, thereby avoiding excessive pressure on the second connecting pipe 33 and the rotating electrolysis cell 1 body, resulting in damage to both, and thus ensuring the smooth progress of the entire electrolysis process.
[0061] A plurality of stepped members are further arranged on the special-shaped plate 345. One end of the contact spring 344 abuts against the stepped member on the side away from the movable seat 343. The other side of the contact spring 344 is connected to the bottom of the movable seat 343. The contact spring 344 is in a compressed state. The diameter of the sealing block 347 is larger than the diameter of the support pipe 346. By moving the adjusting component 342, the insertion amount of the movable seat 343 in the support pipe 346 is controlled, the deformation amount of the contact spring 344 is changed, and the pressure applied by the contact spring 344 to the special-shaped plate 345 and the sealing block 347 is adjusted, so as to change the prestress of the sealing block 347 on the transfer sleeve 341, that is, change the air pressure when the gas pushes the sealing block 347 to move towards the adjusting component 342 direction. By arranging the stepped members on the special-shaped plate to form an area for placing the contact spring 344 between the stepped members and the movable seat 343, the sealing block 347 can be pushed through the deformation of the contact spring 344, and the sealing or the guiding work of the air flow can be completed.
[0062] The adjusting assembly 342 includes a housing 3421 connected to the adapter sleeve 341, an adjusting seat 34210 disposed within the housing 3421, a lead screw linear motion mechanism 3422 provided on the adjusting seat 34210, a driven part connected to the lead screw linear motion mechanism 3422, vertical slide rails 3427 symmetrically arranged on the driven part, and a slider 3428 disposed on the inner wall of the adjusting seat 34210 and slidably connected to the vertical slide rails 3427; the driven part includes a driving seat 3423 connected to the lead screw linear motion mechanism 3422, first slide rails 3424 symmetrically arranged on the driving seat 3423, second slide rails 3425 slidably connected to the first slide rails 3424, a driven seat 3426 for connecting the second slide rails 3425, and a driving ring 3429 provided on the driven seat 3426; the driving seat 3423 and the driven seat 3426 have the same right trapezoidal structure, and the inclined surfaces of the two right trapezoids are placed opposite to each other; wherein the length and width surfaces of the first slide rails 3424 and the second slide rails 3425 are parallel to the inclined surface of the right trapezoid; the driving ring 3429 is connected to the movable seat 343; the first slide rails 3424 are provided with elongated protrusions, and the second slide rails 3425 are provided with sliding grooves adapted to the protrusions;
[0063] Before the electrolytic hydrogen production work is required, the lead screw linear motion mechanism 3422 starts to work. The moving lead screw linear motion mechanism 3422 can drive the driving seat 3423 to start working. The moving driving seat 3423 can apply a thrust to the driven seat 3426, thereby causing a relative displacement between the first slide rails 3424 and the second slide rails 3425. Then, the driven seat 3426 can vertically lift under the cooperation of the second slide rails 3425 and the vertical slide rails 3427, thereby adjusting the position of the driving ring 3429, and further adjusting the position of the movable seat 343, so that the movable seat 343 can limit the moving distance of the special-shaped plate 345, thereby changing the deformation amount of the abutting spring 344 between the movable seat 343 and the special-shaped plate 345, and thereby applying a set prestress to the sealing block 347. That is, when the air pressure in the second connecting pipe 33 is greater than this prestress, the gas can enter the temporary storage tank 35 along the adapter sleeve 341. At the same time, the device can also be self-adjusted during the electrolysis process, so that the gas can be located in the temporary storage tank 35, reducing the pressure on the second connecting pipe 33 and the rotating electrolytic cell 1 body, and avoiding damage to both.
[0064] The liquid injection device 4 includes a tubular limit seat 41 fixedly installed on the rotary electrolytic cell 1. A plurality of extension rods extending towards the center of the limit seat 41 are provided on the inner wall of the limit seat 41, a clamping cylinder 42 provided on the extension rods, a driving frame 43 for connecting the output end of the clamping cylinder 42, and a clamping portion provided on the driving frame 43. The axis of the driving frame 43 coincides with the axis of the limit seat 41. The limit seat 41 includes a limit tube 48 and a driving base 44 connected to the limit tube 48. A frustum-shaped groove is provided on the driving base 44. The clamping portion includes at least three connecting rods 45 movably connected to the driving frame 43, and two limit wheels 46 respectively provided at both ends of the connecting rods 45. One of the limit wheels 46 abuts against the inner wall of the limit seat 41, and the other limit wheel 46 abuts against the inner wall of the groove on the driving base 44. By the operation of the clamping cylinder 42, the position of the driving frame 43 in the axial direction of the limit seat 41 is adjusted, the position of the limit wheel 46 in the groove is changed, so as to change the distance between the limit wheels 46 at the other end of the connecting rod 45, and the clamping work of the electrolyte delivery pipe is completed.
[0065] When electrolytic hydrogen production work needs to be carried out, at this time, the operator or the manipulator can hold one end of the delivery pipe for delivering the electrolyte, and make it pass smoothly through the placement hole on the limit tube 48 and extend to the established electrolyte injection position in the electrolytic cell. At this time, the elastic piece 47 abuts against the outer wall of the delivery pipe. One end of the delivery pipe is located in the water tank in the electrolytic cell. Then the clamping cylinder 42 starts to work. The moving clamping cylinder 42 can drive the driving frame 43 to start working, adjust the position of the driving frame 43 in the axial direction of the limit seat 41. Furthermore, the moving driving frame 43 can drive the connecting rod 45 to move, so that the limit wheel 46 at one end of the connecting rod 45 slides on the inner wall of the groove on the driving base 44, thereby changing the distance between the limit wheels 46 at the other end of the connecting rod 45. The adjustment methods of the limit wheels 46 at both ends are opposite, that is, when the limit wheels 46 at one end approach each other, the limit wheels 46 at the other end will move away from each other, and vice versa. Furthermore, the limit wheel 46 away from the driving base 44 can abut against the outer wall of the delivery pipe to complete the clamping and limiting work of the delivery pipe.
[0066] A limiting tube 48 is further provided on the driving frame 43, a protruding end 49 respectively arranged on the connecting rod 45 and the limiting tube 48, and a return spring 410 for connecting the two protruding ends 49; an internal thread is provided on the driving frame 43, and an external thread is provided on the limiting tube 48, and the limiting tube 48 is installed on the driving frame 43 through the set internal and external threads; the limiting tube 48 is of a tubular structure, a placing hole is opened in its axial direction, a plurality of elastic pieces 47 arranged at one end of the placing hole and connected to the limiting tube 48, and an elastic member arranged on the inner wall of the limiting tube 48; through the set return spring 410, during the process of the driving frame 43 reciprocating in the circumferential direction of the limiting seat 41, one of the limiting wheels 46 is in contact with the inner wall of the limiting seat 41, thereby ensuring the stability of the driving frame 43, avoiding the deviation of the output end of the conveying pipe, resulting in the deviation of the injection angle of the electrolyte, and further causing contact with the device, resulting in the damage of the device.
[0067] In a further embodiment, when the conveying pipe is inserted into the water tank, in order to ensure that the electrolyte can enter the water tank, the insertion depth is greater than the established depth. When the conveying pipe is clamped later, the device can not only complete the clamping work of the conveying pipe, but also improve its position in the axial direction of the limiting seat 41, thereby adjusting the insertion depth of the conveying pipe, avoiding the conveying pipe being inserted too deep and located below the established liquid level of the water tank. The elastic piece 47 is a plastic elastic piece. After the liquid injection work is completed, through the set elastic member and elastic piece 47, the electrolyte attached to the end of the conveying pipe can be intercepted, so that it can be located in the limiting tube 48, avoiding the leakage of the electrolyte. At the same time, the limiting tube 48 can be replaced to complete the interception of the electrolyte and avoid the dripping of the electrolyte.
[0068] In a further embodiment, two gas storage tanks 32 are provided in the device, which can be used alternately or separately. When used alternately, the gas in the gas storage tank 32 can be a mixed gas. The gas storage tank 32 can also collect the corresponding hydrogen and oxygen through existing collection equipment. At the same time, when used separately, the positions of the first connecting pipes connected to the two gas storage tanks 32 on the rotary electrolytic cell 1 are different, and according to the different gases, the connection positions of the first connecting pipes are different.
[0069] Principle description: Before the electrolytic hydrogen production work is required, the lead screw linear motion mechanism 3422 starts to work. The moving lead screw linear motion mechanism 3422 can drive the driving seat 3423 to start working. The moving driving seat 3423 can apply a thrust to the driven seat 3426, so that a relative displacement occurs between the first slide rail 3424 and the second slide rail 3425. Then, the driven seat 3426 can vertically lift under the cooperation of the second slide rail 3425 and the vertical slide rail 3427, so as to adjust the position of the driving ring 3429, and then adjust the position of the movable seat 343, so that the movable seat 343 can limit the moving distance of the special-shaped plate 345, thereby changing the deformation amount of the abutting spring 344 between the movable seat 343 and the special-shaped plate 345, and applying a set prestress to the sealing block 347. That is, when the air pressure in the second connecting pipe 33 is greater than this prestress, the gas can enter the temporary storage tank 35 along the adapter sleeve 341;
[0070] When electrolytic hydrogen production work is required, at this time, the operator or the manipulator can hold one end of the delivery pipe for delivering the electrolyte, and make it pass smoothly through the placement hole on the limit pipe 48 and extend to the established electrolyte injection position in the electrolytic cell. At this time, the elastic piece 47 abuts against the outer wall of the delivery pipe. One end of the delivery pipe is located in the water tank in the electrolytic cell. Then, the clamping cylinder 42 starts to work. The moving clamping cylinder 42 can drive the driving frame 43 to start working, adjust the position of the driving frame 43 in the axial direction of the limit seat 41. Then, the moving driving frame 43 can drive the connecting rod 45 to move, so that the limit wheel 46 at one end of the connecting rod 45 slides on the inner wall of the groove of the driving base 44, thereby changing the distance between the limit wheels 46 at the other end of the connecting rod 45. The adjustment methods of the limit wheels 46 at both ends are opposite, that is, when the limit wheels 46 at one end approach each other, the limit wheels 46 at the other end will move away from each other, and vice versa. Then, the limit wheel 46 away from the driving base 44 can abut against the outer wall of the delivery pipe to complete the clamping and limiting work of the delivery pipe, avoiding the offset of the liquid injection end of the delivery pipe due to the too high flow rate of the electrolyte in the delivery pipe, thereby causing the leakage of the electrolyte;
[0071] After completing the work of delivering the electrolyte in the water tank, the rotary electrolyzer 1 starts to work at this time, and then corresponding gases can be generated. At this time, the gases can flow along the first connecting pipe and enter the gas storage tank 32 through the flow dividing unit 31. The gas storage tank 32 can be used to store hydrogen or oxygen or a mixture of both. Then, when the gas storage tank 32 reaches its predetermined storage capacity, the flow dividing unit 31 starts to work at this time. The flow dividing cylinder 315 in the flow dividing unit 31 starts to work. The moving flow dividing cylinder 315 can drive the driving rod 316 to move, so as to adjust the movement of the pushing block 317 in the first communication cavity, so that the pushing block 317 can block the first air outlet end 312. At this time, the gas moving from the original first air inlet end 313 to the first air outlet end 312 changes to moving from the first air inlet end 313 to the second air outlet end 314, and then can enter the second connecting pipe 33;
[0072] When the gas enters the second connecting pipe 33, the operator can replace the gas storage tank 32 at this time. During this process, the electrolysis speed is not affected. At the same time, if the installation work of the gas storage tank 32 is completed before the air pressure in the second connecting pipe 33 reaches the preset air pressure, the gas can be made to move from the first air inlet end 313 to the first air outlet end 312 and enter the gas storage tank 32 through the work of the flow dividing cylinder 315. On the contrary, the gas exceeding the preset air pressure can make the sealing block 347 move towards the movable seat 343, so that the gas can flow along the adapter sleeve 341 to the temporary storage tank 35, thereby avoiding excessive pressure on the second connecting pipe 33 and the body of the rotary electrolyzer 1, which may cause damage to both, and thus ensuring the smooth progress of the entire electrolysis process.
