Description
TECHNICAL FIELD
[0001] The present application relates to a kind of electrolytic cell shell heat dissipation hole opening and closing equipment, belong to aluminum electrolysis equipment technical field. BACKGROUND
[0002] At present, the heat dissipation of aluminum electrolytic cell mainly relies on the natural convection and radiation of the cell shell surface. The design of the cell shell, including its size, material and the arrangement of the heat dissipation ribs, is based on a preset thermal equilibrium point. However, in the actual production process, the thermal state of the electrolytic cell will be dynamically disturbed by various factors, such as:
[0003] 1. Series current fluctuation: peak-valley electricity price flexible production leads to current fluctuation, which directly affects the heat generation in the cell.
[0004] 2. Ambient temperature change: seasonal change, such as winter and summer, causes the temperature of the workshop environment to change, significantly changing the heat dissipation rate of the cell body.
[0005] 3. Cell age change: as the running time of the electrolytic cell increases, the lining material in the cell will change, and the thickness and shape of the side furnace wall will also change, affecting the thermal resistance and heat dissipation.
[0006] The existing cell shell structure is static and passive. Its heat dissipation capacity is fixed after design and construction, and it cannot respond to the above dynamic thermal disturbance. When the heat income in the cell is greater than the heat expenditure, the cell temperature will rise, which may melt the side furnace wall, erode the lining in the cell, and even cause serious safety accidents such as cell leakage; on the contrary, when the heat income is insufficient, the furnace wall will thicken excessively, causing the furnace to shrink, the current distribution to be uneven, and ultimately affecting the current efficiency and energy consumption.
[0007] The industry focuses more on adjusting the process parameters such as cell distance, aluminum level and electrolyte level to adjust the heat income in the aspect of thermal balance control, and there are very few active adjustment methods for heat expenditure (i.e. heat dissipation). Most attempts involve manual intervention, such as manually closing some ventilation openings or adding insulation boards in winter, but this method is slow in response, low in precision and cannot achieve precise closed-loop control.
[0008] Therefore, it is of great significance to develop a device that can actively and timely respond to changes in the temperature of the electrolytic cell and adjust the heat dissipation intensity in time to realize "precise thermal management" of the aluminum electrolytic cell. SUMMARY

DETAILED DESCRIPTION
[0035] The application will be further described below in conjunction with the drawings and examples, but not as the basis for limiting the application.
[0036] The embodiment of the application: a kind of pot shell heat dissipation hole opening and closing equipment, including outer shell 4, outer shell 4 is movably installed with slid 1, the upper end of slid 1 from outer shell 4 extends, reset spring 2 and pull rod 3 are also provided in outer shell 4, the two ends of reset spring 2 are fixedly connected with slid 1 and outer shell 4, pull rod 3 bottom is connected with outer shell 4, and its upper end is clamped into the guide slot 5 of the similar back type of slid 1.
[0037] Slid 1 includes extended block 11 and slid main body 12 respectively located at the left and right sides of outer shell 4, and left bottom oblique block 13, middle V-shaped block 14 and top conical block 15 are dispersedly arranged on the surface of extended block 11, guide slot 5 is arranged on the surface of extended block 11, guide slot 5 is composed of left oblique guide slot 16, top V-shaped guide slot 17 and right vertical guide slot 18, the bottom of left oblique guide slot 16 is communicated with the bottom of right vertical guide slot 18, the top is communicated with the left end of top V-shaped guide slot 17, and the right end of top V-shaped guide slot 17 is communicated with the top of right vertical guide slot 18. The left oblique guide slot 16 is formed between the left oblique edge of left bottom oblique block 13 and middle V-shaped block 14, the top V-shaped guide slot 17 is formed between the top of middle V-shaped block 14 and the bottom of top conical block 15, and the right vertical guide slot 18 is formed between the right side of middle V-shaped block 14 and slid main body 12. When reset spring 2 is not stretched, the head end of pull rod 3 is clamped into left oblique guide slot 16.
[0038] As Figure 1 , 6and 8, at this time the reset spring 2 is in the non-stretching state, the closed end cap 6 of the head end of the slider 1 just extends into the heat dissipation hole, when the heat dissipation hole needs to be opened, the slider 1 is pressed downward, so that the slider 1 slides vertically downward in the shell 4, the slider 1 slides downward, which drives the reset spring 2 to stretch, at this time the head end of the pull rod 3 slides upward along the left inclined guide groove 16, the pull rod 3 is extruded and rotated by a certain angle during the sliding process, when the pull rod 3 enters the top V-shaped guide groove 17 from the left inclined guide groove 16 and contacts the top wall, at this time the slider 1 cannot continue to go down, the slider 1 is released, and the slider 1 is driven to go upward under the elastic force of the reset spring 2, at this time the head end of the pull rod 3 slides along the top V-shaped guide groove 17, when the head end of the pull rod 3 moves to the lowest point (point A) of the top V-shaped guide groove 17, the head end of the pull rod 3 blocks the middle V-shaped block 14, the slider 1 cannot continue to go upward under the elastic force of the reset spring 2, at this time the slider 1 is just in the state shown in Figure 7 、 Figure 9 , at this time the heat dissipation hole remains in the open state. When the heat dissipation hole needs to be closed, the slider 1 is pressed again, at this time the pull rod 3 slides upward along the right guide groove of the top V-shaped guide groove 17, when the pull rod 3 enters the right vertical guide groove 18 and contacts the top wall, the slider 1 cannot continue to go down, the slider 1 is released, and the slider 1 is driven to go upward under the elastic force of the reset spring 2, during the process, the pull rod 3 slides along the right vertical guide groove 18, as the slider 1 goes upward, the pull rod 3 finally moves from the top of the right vertical guide groove 18 to the head end position of the left inclined guide groove 16, that is, the position shown in Figure 1 , at this time the heat dissipation hole is in the closed state.
[0039] The pull rod 3 is provided with downward bent heads 19 at both ends, the upper bent head 19 is clamped into the guide groove 5, and the lower bent head 19 is clamped into the limiting hole 20 at the bottom of the shell 4, the limiting hole 20 fixes the pull rod 3 and does not limit the rotation of the pull rod 3.
[0040] The top end bottom surface height of the left inclined guide slot 16 is higher than the left end bottom surface height of the top V-shaped guide slot 17, the top V-shaped guide slot 17 is divided into left and right parts, the left bottom surface height is higher than the right bottom surface height, the right end bottom surface height of the top V-shaped guide slot 17 is higher than the top end bottom surface height of the right vertical guide slot 18, the bottom end bottom surface height of the right vertical guide slot 18 is higher than the bottom end bottom surface height of the right vertical guide slot 18, and the bottom surface of each guide slot is smooth. The structure forms a step 22 at the joint of each guide slot, that is, the bottom surface of the tail end of the previous guide slot is higher than the bottom surface of the head end of the next guide slot. The pull rod 3 has a elastic structure, so that the head end of the pull rod 3 is always in contact with the bottom surface of the guide slot during movement. Due to the step 22, it is ensured that the pull rod 3 will not be accidentally pulled out from the locking position under vibration or external force interference, and reverse movement will not occur. Moreover, during the process of loosening the sliding block 1, when the reset spring 2 drives the sliding block 1 to slide upward, the bottom of the pull rod 3 will be in contact with the step 22 at the joint of the adjacent guide slot, and will be blocked by the step 22, so that the pull rod 3 can only slide in the next guide slot. For example, when the heat dissipation hole needs to be opened, the sliding block 1 vertically slides downward in the shell 4, at this time the head end of the pull rod 3 slides upward along the left inclined guide slot 16, when the pull rod 3 enters the top V-shaped guide slot 17 from the left inclined guide slot 16 and contacts the top wall, at this time the sliding block 1 cannot continue to slide downward, the sliding block 1 is loosened, and the reset spring 2 drives the sliding block 1 to slide upward. Since the head end of the pull rod 3 is always in contact with the bottom surface of the guide slot, and the pull rod 3 has entered the top V-shaped guide slot 17, the bottom surface of the top V-shaped guide slot 17 is lower than the bottom surface of the left inclined guide slot 16, when the sliding block 1 slides upward, the head end of the pull rod 3 will be blocked by the step 22 at the joint of the left inclined guide slot 16 and the top V-shaped guide slot 17, so that the pull rod 3 cannot enter the left inclined guide slot 16, and can only slide along the top V-shaped guide slot 17. After the step 22 is arranged, the pull rod 3 can only enter the left guide slot of the top V-shaped guide slot 17 from the left inclined guide slot 16, then enter the right guide slot of the top V-shaped guide slot 17, then enter the right vertical guide slot 18 from the right guide slot, and finally enter the left inclined guide slot 16 from the right vertical guide slot 18, so as to ensure that the pull rod 3 will not reverse.
[0041] The end of the sliding block 1 extending out of the shell 4 is provided with a closed end cover 6, the shape and size of the closed end cover 6 are adapted to the heat dissipation hole, and the closed end cover 6 extends into the heat dissipation hole when the sliding block 1 slides upward to reset, so as to realize the closure of the heat dissipation hole.
[0042] The housing 4 is internally provided with a protruding rib 7 and a groove 8 adjacent to the length direction, and the slider 1 is provided with a protrusion 9 and a clamping groove 10 adjacent to the bottom, the protrusion 9 is clamped into the groove 8, and the protruding rib 7 is clamped into the clamping groove 10, so that the slider 1 is stably up and down sliding, and the closed end cover 6 at the top of the slider 1 is just extended into the heat dissipation hole after the upward reset.
[0043] The left upper part of the housing 4 is a reset spring 2 mounting area, and a reset spring limiting column 21 is arranged on the top of the housing 4 and the top of the reset spring 2 mounting area, so that the two ends of the reset spring 2 are hung on the reset spring limiting column 21, and the reset spring 2 is quickly mounted.
[0044] The bottom surface of the extension block 11 is inwardly recessed, so that the contact area of the bottom surface of the extension block 11 and the inner bottom surface of the housing 1 is reduced, the friction force suffered by the slider 1 during sliding is reduced, and the smooth sliding of the slider 1 is ensured.
[0045] The bottom of the slider 1 on the right side of the protrusion 9 is spaced apart from the inner surface of the housing 4, so that the contact area of the bottom of the slider 1 and the inner bottom surface of the housing 1 is reduced, the friction force suffered by the slider 1 during sliding is reduced, and the smooth sliding of the slider 1 is ensured.
[0046] The electrolytic cell shell heat dissipation hole opening and closing device based on temperature regulation mainly comprises a slider 1, a reset spring 2, a pull rod 3 and a housing 4.
[0047] The pressing locking process is as follows: when the slider 1 is pressed downward, the pull rod 3 automatically moves along the guide groove 5, and after stopping pressing, the pull rod 3 moves to the A point position, and the slider 1 should reset to the initial position under the action of the reset spring 2, but the slider 1 cannot reset due to being hooked at the A point position by the pull rod 3, and is locked at this position, which is also the position of the opening of the heat dissipation hole.
[0048] The pop-up process is as follows: when the slider 1 is pressed again, the pull rod 3 automatically moves along the guide groove 5, and after the hand is released, the pull rod 3 returns to the initial position, and the slider 1 resets to the initial position under the action of the reset spring 3, which is also the position of the closing of the heat dissipation hole.
[0049] The guide groove 5 is designed with a step 22 at the turning position, so that the pull rod 3 can only move along a specific track and cannot reverse, effectively preventing accidental unhooking or reverse movement caused by vibration, spring force or other external forces during locking or resetting, thereby ensuring the stability and reliability of the locking and closing states.
[0050] The electrolytic cell shell heat dissipation hole opening and closing device of the application is composed of only four core components, i.e., a sliding block 1, a reset spring 2, a pull rod 3 and a shell 4, has a small number of components and a simple structure, means that there are few failure points, has more advantages in production, installation and maintenance and has higher working reliability.
[0051] The electrolytic cell shell heat dissipation hole opening and closing device of the application has a compact structure, can be conveniently welded below the heat dissipation hole, does not occupy too much extra space and is very suitable for the environment of electrolytic cells with limited space.
[0052] The electrolytic cell shell heat dissipation hole opening and closing device of the application is directly corresponding to the "closed" and "open" states of the heat dissipation hole when the sliding block 1 is in different physical positions and pops up or is pressed down, and an operator can very intuitively judge the current state.
[0053] The above is only a specific embodiment of the application, but the protection scope of the application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the application, which should be covered in the protection scope of the application, therefore, the protection scope of the application should be subject to the protection scope of the claims.
