[0042] Example 1

[0043] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes an electrolytic cell liquid level regulating device, including: an outer sleeve 1 and an inner sleeve 2 rotatably arranged in the outer sleeve 1, the outer sleeve 1 is provided with a leakage port 101, the inner sleeve 2 is provided with an adjustment port 201, and after the inner sleeve 2 rotates, the adjustment port 201 is connected to the leakage port 101; there are a plurality of leakage ports 101, and the plurality of leakage ports 101 are spirally arranged on the outer sleeve 1, and there is a height difference between two adjacent leakage ports 101.

[0044] In this embodiment, the outer sleeve 1 serves as the main structure of the entire device, and the outer sleeve 1 plays a supporting and fixing role. Its material is usually a corrosion-resistant material with excellent insulation performance to adapt to the chemical environment in the electrolytic cell. The outer sleeve 1 is provided with a spirally distributed leakage port 101. The inner sleeve 2 is rotatably arranged in the outer sleeve 1, and forms a sealing fit with the outer sleeve 1 to reduce electrolyte leakage. An adjustment port 201 is provided on the inner sleeve 2. By rotating the inner sleeve 2, the relative position of the adjustment port 201 and the leakage port 101 on the outer sleeve 1 can be changed to achieve the discharge and control of the electrolyte. Several leakage ports 101 are spirally arranged on the outer sleeve 1, and there is a height difference between two adjacent leakage ports 101, which means that by rotating the inner sleeve 2, the connection state between the adjustment port 201 and the leakage ports 101 at different heights can be changed, thereby achieving precise control of the electrolyte discharge amount. The working principle and use process are as follows: the regulating port 201 on the inner sleeve 2 is connected to the leakage port 101 at a certain height on the outer sleeve 1, and the electrolyte flows into the leakage port 101 from the regulating port 201 and is discharged from the electrolytic cell through the leakage port 101 to maintain the liquid level in the electrolytic cell.

[0045] In this embodiment, when the liquid level of the electrolytic cell needs to be adjusted, the inner sleeve 2 is rotated to change the relative position of the regulating port 201 and the liquid leakage port 101. If it is desired to lower the liquid level, the regulating port 201 is aligned with the liquid leakage port 101 at a lower height to increase the amount of electrolyte discharged; conversely, if it is desired to increase the liquid level, the regulating port 201 is aligned with the liquid leakage port 101 at a higher height to reduce the amount of electrolyte discharged. Through the above design, the device has the characteristics of simple structure, intuitive operation, and precise liquid level control, which is conducive to improving the working efficiency and stability of the electrolytic cell, reducing maintenance costs, and is suitable for electrolytic cell systems of various sizes and types.

[0046] Example 2

[0047] Reference Figure 4~Figure 6 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the outer sleeve 1 also has a locking groove 102, and the locking groove 102 is arranged at the end of the outer sleeve 1; it also includes: a locking block 3 is slidably arranged on the outer wall of the inner sleeve 2, and after the inner sleeve 2 rotates, the locking block 3 and the locking groove 102 are engaged or canceled.

[0048] Optionally, the outer sleeve 1 also has a positioning groove 103, which is arranged at the end of the outer sleeve 1, below the locking groove 102, and connected to the locking groove 102; it also includes: a positioning block 4 is arranged at one end of the locking block 3, and after the locking block 3 is engaged with the locking groove 102, the positioning block 4 is engaged with the positioning groove 103.

[0049] Optionally, the positioning groove 102 is conical, the positioning block 3 is a frustum, the positioning groove 103 is a spherical groove, the positioning block 4 is a sphere, and the positioning block 4 is arranged at the end of the positioning block 3 with the smallest cross-section.

[0050] Compared with Example 1, further, a positioning groove 102, a positioning block 3, a positioning groove 103 and a positioning block 4 are additionally provided on the basis of Example 1 to achieve accurate positioning and locking of the inner sleeve 2 relative to the outer sleeve 1, thereby ensuring the accuracy and stability of liquid level adjustment. Specific improvements are as follows:

[0051] A positioning groove 102 is provided at the top of the outer sleeve 1, and a positioning block 3 is slidably provided on the outer wall of the inner sleeve 2. The positioning groove 102 is in a frustum state, and the positioning block 3 is a frustum. The positioning groove 102 is adapted to the shape of the positioning block 3, and the end of the positioning groove 102 with the smallest cross section points to the bottom of the outer sleeve 1, so as to realize the snap fit between the positioning block 3 and the positioning groove 102. The setting of the positioning groove 102 enables the positioning of the inner sleeve 2 when the inner sleeve 2 is rotated to a specific position through the cooperation between the positioning block 3 and the positioning groove 102, thereby reducing the rotation of the inner sleeve 2 due to vibration, pressure and other factors in a non-operating state. When the inner sleeve 2 is rotated to the position of the leakage port 101 corresponding to the required liquid level, the positioning block 3 is slid to align it with the positioning groove 102, so as to realize the snap fit between the inner sleeve 2 and the outer sleeve 1.

[0052] A positioning groove 103 connected to the positioning groove 102 is arranged at the top of the outer sleeve 1, and a positioning block 4 is arranged at one end of the positioning block 3. The positioning groove 103 is spherical, and the positioning block 4 is a sphere. The positioning block 4 is arranged at the end of the positioning block 3 with the smallest cross section. The shape and size of the positioning groove 103 should be precisely matched with the positioning block 4 to achieve the clamping fit between the positioning block 4 and the positioning groove 103. The arrangement of the positioning groove 103 and the positioning block 4 further enhances the positioning accuracy of the inner sleeve 2 and the outer sleeve 1, and reduces the misalignment or loosening of the positioning block 3 and the positioning groove 102 during the clamping process. When the positioning block 3 is clamped and matched with the positioning groove 102, the positioning block 4 can be inserted into the positioning groove 103 to achieve accurate locking of the inner sleeve 2 and the outer sleeve 1. The design of the positioning block 4 makes the inner sleeve 2 more stable in the locked state, and reduces the change in the relative position of the inner sleeve 2 and the outer sleeve 1 due to unexpected factors, which affects the accuracy of the liquid level adjustment. By adding the positioning groove 102, the positioning block 3, the positioning groove 103 and the positioning block 4, the electrolytic cell liquid level regulating device proposed in this embodiment further improves the positioning accuracy and locking stability of the inner sleeve 2 and the outer sleeve 1 on the basis of the original liquid level regulating function, thereby ensuring the accuracy and stability of liquid level regulation. This design is particularly suitable for electrolytic cell systems that have high requirements for liquid level control, need to frequently adjust the liquid level, or need to prevent liquid level changes in non-operating states.

[0053] Example 3

[0054] Reference Figure 4~Figure 6 , which is the third embodiment of the utility model. This embodiment is different from the second embodiment in that: there are a plurality of positioning grooves 102 and positioning grooves 103, and the plurality of positioning grooves 102 and the plurality of positioning grooves 103 are circumferentially distributed at the end of the outer sleeve 1, and the positioning grooves 102 correspond to the positioning grooves 103 one by one.

[0055] Compared with Example 2, the positioning groove 102 and the positioning groove 103 are further improved, and several positioning grooves 102 and positioning grooves 103 are added, and the circumference is distributed at the end of the outer sleeve 1, forming a multi-point positioning and locking mechanism, further improving the positioning accuracy and locking stability of the inner sleeve 2 and the outer sleeve 1. The specific improvements are as follows: there are several positioning grooves 102 and positioning grooves 103, and the several positioning grooves 102 and the several positioning grooves 103 are all distributed circumferentially at the end of the outer sleeve 1, and the positioning grooves 102 and the positioning grooves 103 correspond one to one. This means that when the inner sleeve 2 is rotated to the position of the leakage port 101 corresponding to any liquid level, the positioning and locking of the inner sleeve 2 can be achieved through the cooperation of the positioning block 3 and the positioning groove 102, and the positioning block 4 and the positioning groove 103. The setting of multiple positioning grooves 102 and positioning grooves 103 forms a multi-point positioning and locking mechanism for the inner sleeve 2. When the inner sleeve 2 rotates to the position of the leakage port 101 corresponding to the required liquid level, the inner sleeve 2 is aligned with any of the positioning grooves 102 by sliding the positioning block 3, and then the positioning block 4 is engaged with the corresponding positioning groove 103 to achieve precise locking of the inner sleeve 2 and the outer sleeve 1. This multi-point positioning and locking mechanism makes the inner sleeve 2 more stable and more resistant to interference in the locked state, preventing the relative position of the inner sleeve 2 and the outer sleeve 1 from changing due to unexpected factors, thereby affecting the accuracy of the liquid level adjustment. On the basis of the original liquid level adjustment function, the positioning accuracy and locking stability of the inner sleeve 2 and the outer sleeve 1 are further improved, forming a multi-point positioning and locking mechanism to ensure the accuracy and stability of the liquid level adjustment. This design is particularly suitable for electrolytic cell systems that have high requirements for liquid level control, need to frequently adjust the liquid level, or need to prevent liquid level changes in non-operating states.

[0056] Example 4

[0057] Reference Figure 4~Figure 6 , which is the fourth embodiment of the utility model. This embodiment is different from the second and third embodiments in that: the first sleeve 5 is arranged on the inner sleeve 2; the first slide bar 6 is slidably arranged in the first sleeve 5, and the end of the blocking block 3 with a larger cross-section is arranged at the end of the first slide bar 6, and the first slide bar 6 is used to drive the blocking block 3 to slide; the first handle 7 is arranged at the end of the first slide bar 6 away from the blocking block 3; the first elastic member 8 is sleeved on the first slide bar 6, and the two ends act on the first sleeve 5 and the first slide bar 6 respectively, and the first elastic member 8 is used to provide a force for the blocking block 3 to approach the blocking groove 102.

[0058] Compared with Embodiment 2 and Embodiment 3, a first sleeve 5, a first slide bar 6, a first handle 7 and a first elastic member 8 are further provided to realize convenient operation and automatic reset of the positioning block 3, and further improve the convenience and stability of liquid level adjustment. The specific improvements are as follows: a first sleeve 5 is provided on the inner sleeve 2, and a sliding space is provided inside the first sleeve 5 for accommodating the first slide bar 6. The first slide bar 6 is slidably arranged in the first sleeve 5, and one end thereof is connected to the end with a larger cross-section of the positioning block 3. By sliding the first slide bar 6, the positioning block 3 can be driven to slide, so that the positioning block 3 is close to or away from the positioning groove 102, so as to adjust the relative position of the inner sleeve 2 and the outer sleeve 1. A first handle 7 is provided at the other end of the first slide bar 6, and by operating the first handle 7, the sliding of the first slide bar 6 can be conveniently controlled. The shape and size of the first handle 7 should be convenient for the operator to hold and apply force. By operating the first handle 7, the sliding of the first slide bar 6 can be easily controlled, and then the position of the positioning block 3 can be adjusted to realize liquid level adjustment. The first elastic member 8 is sleeved on the first slide bar 6 , and two ends of the first elastic member 8 act on the first sleeve 5 and the first slide bar 6 respectively to provide restoring force for the first slide bar 6 .

[0059] The specific working process is as follows: when the operator needs to adjust the liquid level, the operator first rotates the inner sleeve 2 to rotate the adjustment port 201 on the inner sleeve 2 to communicate with the leakage port 101 on the outer sleeve 1. During this process, the top of the outer sleeve 1 squeezes the positioning block 4 to compress the first elastic member 8. When the adjustment port 201 is connected with the appropriate leakage port 101, the positioning block 4 points to the corresponding positioning groove 103, and the positioning block 3 points to the corresponding positioning groove 102. At this time, the first elastic member 8 loses pressure, so that the positioning platform is engaged with the corresponding positioning groove 102, and the positioning block 4 is engaged with the corresponding positioning groove 103, so that the inner sleeve 2 and the outer sleeve 1 are locked. The operator can pull the first handle 7 upwards. At this time, the first elastic member 8 is subjected to an upward pulling force and deformed, so that the positioning block 4 is separated from the positioning groove 103, and the positioning block 3 is separated from the positioning groove 102. At this time, the inner sleeve 2 and the outer sleeve 1 are unlocked, and the operator can continue to rotate the inner sleeve 2 to adjust the liquid level. By adding the first sleeve 5, the first slide bar 6, the first handle 7 and the first elastic member 8 on the basis of the original liquid level adjustment function, the convenience and stability of the liquid level adjustment are improved.
