Description

Technical Field

[0001] The invention relates to the technical field of electrolyzers, in particular to a rotating electrolyzer with a built-in hydrogen storage tank. Background Art

[0002] An electrolyzer is a device for electrolysis, consisting of a cell body, an anode and a cathode, and most of them use a diaphragm to separate the anode chamber from the cathode chamber. It is widely used in many fields such as metal smelting, chemical synthesis, and electroplating processes. It causes the ions in the electrolyte solution to undergo redox reactions through an applied potential to produce the desired chemical substances. Among them, a rotating electrolyzer is an electrolyzer that promotes the electrolysis reaction by rotating electrodes. Its characteristic is that at least one electrode (usually the cathode) can rotate. This design can optimize ion transmission and bubble separation during the electrolysis process, thereby improving the electrolysis efficiency.

[0003] For example, a Chinese patent application with publication number CN116815216A discloses a rotating electrolyzer with a built-in hydrogen storage tank, comprising: a water tank is provided on the top of the rotating electrolyzer body, the bottom of the water tank is connected to a reaction chamber through a water tank water guide one-way valve, a plurality of partitions are arranged in sequence from top to bottom in the reaction chamber, a positive electrode sheet is provided on the upper surface of each partition, a negative electrode sheet is provided on the lower surface of each partition, a slip ring is provided in a conductive slip ring housing, the slip ring electrically connects the positive electrode sheet and the negative electrode sheet to supply power thereto; and the reaction chamber is connected to the hydrogen storage tank through a one-way valve.

[0004] However, there are still some problems with the above patent. In the above patent, when the rotating electrolyzer has been working for a period of time and the gas in the hydrogen storage tank reaches the maximum capacity, the hydrogen storage tank needs to be disassembled and replaced. During this process, the operator either chooses to stop the electrolysis or continue the electrolysis. The start and stop of the device will cause a large energy loss.

[0031] In a further embodiment, when the delivery 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 a predetermined depth. When the delivery pipe is clamped at a later stage, the device can not only complete the clamping of the delivery pipe, but also lift its position in the axial direction of the limit seat 41, thereby adjusting the insertion depth of the delivery pipe to prevent the delivery pipe from being inserted too deeply and being below the predetermined liquid level in the water tank. The spring clip 47 is a plastic spring clip. After the injection work is completed, the electrolyte attached to the end of the delivery pipe can be retained by the elastic member and the spring clip 47, so that it can be located in the limit tube 48 to avoid leakage of the electrolyte. At the same time, the limit tube 48 can be replaced to complete the retention of the electrolyte and avoid dripping of the electrolyte.

[0032] In a further embodiment, two gas tanks 32 are provided in the device, which can be used alternately or separately. When used alternately, the gas in the gas tank 32 can be a mixed gas, and the gas tank 32 can also collect corresponding hydrogen and oxygen through existing collection equipment. At the same time, when used separately, the first connecting pipe connected to the two gas tanks 32 has a different position on the rotating electrolyzer 1, and the connection position of the first connecting pipe is different depending on the gas.

[0033] Working principle description: before the electrolysis hydrogen production work is required, the screw linear motion mechanism 3422 starts to work, the moving screw linear motion mechanism 3422 can drive the driving seat 3423 to start working, and the moving driving seat 3423 can apply a thrust to the driven seat 3426, thereby causing a relative displacement between the first slide rail 3424 and the second slide rail 3425, and then the driven seat 3426 can be vertically lifted and lowered under the cooperation of the second slide rail 3425 and the vertical slide rail 3427, thereby adjusting the position of the driving ring 3429, and then 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, 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 the prestress, the gas can enter the temporary storage tank 35 along the adapter sleeve 341; When it is necessary to carry out electrolytic hydrogen production, 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 go deep into the predetermined electrolyte injection position of the electrolytic cell. At this time, the spring piece 47 abuts against the outer wall of the delivery pipe, and one end of the delivery pipe is located in the water tank in the electrolytic cell. Then the clamping cylinder 42 starts to work, and 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, and then the moving driving frame 43 can drive the connecting rod 45 to move. The limiting 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 limiting wheels 46 at the other end of the connecting rod 45. The limiting wheels 46 at both ends are adjusted in opposite ways, that is, when the limiting wheels 46 at one end are close to each other, the limiting wheels 46 at the other end will move away from each other, and vice versa. Then, the limiting wheel 46 away from the driving base 44 can abut against the outer wall of the delivery tube to complete the clamping and limiting work of the delivery tube, thereby preventing the infusion end of the delivery tube from being offset due to excessive electrolyte flow rate in the delivery tube, thereby causing electrolyte leakage; After completing the work of transporting the electrolyte in the water tank, the rotating electrolyzer 1 starts to work, and then can generate corresponding gas. At this time, the gas can go along the first connecting pipe and pass through the shunt unit 31 into the gas storage tank 32. The gas storage tank 32 can be used to store hydrogen or oxygen or a mixture of the two. Then, when the gas storage tank 32 reaches the predetermined capacity that it can store, the shunt unit 31 starts to work, and 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, thereby adjusting the propulsion block 317 to move in the first connecting cavity, so that the propulsion block 317 can block the first gas outlet 312. At this time, the gas moves from the original first gas inlet end 313 to the first gas outlet end 312, and then changes from the first gas inlet end 313 to the second gas outlet end 314, and then can enter the second connecting pipe 33; When the gas enters the second connecting pipe 33, the operator can replace the gas tank 32 at this time. During this process, the electrolysis speed will not be affected. At the same time, if the installation of the gas tank 32 is completed before the air pressure in the second connecting pipe 33 reaches the preset air pressure, the gas can be moved from the first air inlet end 313 to the first air outlet end 312 and enter the gas tank 32 through the operation of the diverter cylinder 315. On the contrary, the gas exceeding the preset air pressure can make the sealing block 347 move toward the movable seat 343, so that the gas can move along the adapter sleeve 341 to the temporary storage tank 35, thereby avoiding excessive pressure on the second connecting pipe 33 and the main body of the rotating electrolytic cell 1, which may cause damage to both, thereby ensuring the smooth progress of the entire electrolysis process.
