Description

Technical Field

[0001] This invention relates to the field of dual-anode spraying technology, specifically to a pneumatic control device for a dual-anode support in aluminum electrolysis. Background Technology

[0002] Dual anodes have wide applications in aluminum electrolysis. In traditional aluminum electrolysis processes, single anodes are prone to instability and low efficiency in the electrolytic cell. Dual anodes effectively solve these problems, improving the production efficiency and quality of electrolytic aluminum. Dual anodes can be used not only in aluminum electrolysis but also in the electrolysis of other metals. For example, dual anodes have important applications in the electrolysis of copper, zinc, and nickel. Compared to the traditional single anode structure, dual anodes offer the following advantages in aluminum electrolysis: 1. Increased production efficiency: Dual anodes increase the stability and efficiency of the electrolytic cell, improving aluminum yield and purity. 2. Reduced energy consumption: Dual anodes reduce the resistance of the electrolytic cell, lowering energy consumption during electrolysis and saving energy. 3. Extended equipment lifespan: Dual anodes disperse current density, reducing corrosion and wear in the electrolytic cell and extending equipment lifespan. 4. Improved product quality: Dual anodes promote the transport and deposition rate of aluminum ions, improving the purity and quality of aluminum.

[0003] When spraying dual anode blocks, the assembled anodes need to be placed on a channel steel support frame that is 600mm high, 1700mm wide, and 1700mm long using a forklift. During the spraying of dual anode blocks, the bottom 15cm above the anode does not need to be sprayed because the anode is in direct contact with the aluminum electrolyte. However, during daily spraying, some paint splashing may occur. When spraying manually, some material may fall and spill onto the site. Because ordinary channel steel supports do not have protective plates to prevent material splashing and the welded channel steel supports are relatively high, it is inconvenient for personnel to carry out spraying operations. Summary of the Invention

[0004] To address the aforementioned issues, a pneumatic control device for an aluminum electrolysis dual anode support is provided. This device, through an adaptive pneumatic shielding seat, can effectively improve coating quality and efficiency.

[0005] To address the problems of existing technologies, this invention provides a pneumatic control device for an aluminum electrolysis double anode support, comprising an adaptive pneumatic shielding seat for limiting and shielding the double anode blocks, the adaptive pneumatic shielding seat including an adaptive limiting seat with adaptive adjustable size, multiple fixed enclosures mounted on the adaptive limiting seat, the fixed enclosures being spliced ​​together, a movable enclosure also mounted on the adaptive limiting seat, a pneumatic traction device being installed between the movable enclosure and the fixed enclosure, and a pneumatic shielding plate mounted on both the movable enclosure and the fixed enclosure; The adaptive limit seat includes an adjustable frame that adaptively adjusts its size. The bottom of the adjustable frame is equipped with fixed support legs, and multiple telescopic support frames are also installed inside the adjustable frame. The pneumatic traction device includes a fixed guide plate mounted on a fixed enclosure, several guide wheels mounted on the fixed guide plate, a long shaft cylinder mounted on the side of the fixed enclosure, a second connecting plate mounted on a movable enclosure, a connecting rope mounted on the second connecting plate, the end of the connecting rope away from the second connecting plate passing through the guide wheels and connecting to the output end of the long shaft cylinder, and an elastic booster mounted on the fixed guide plate. The pneumatic shielding plate includes several adjustable mounting guide posts, on which sliding adjustment blocks are mounted, on which splicing baffles are mounted, and at least one pneumatic flipping mechanism is mounted on the sliding adjustment block. The drive end of the pneumatic flipping mechanism is connected to the splicing baffle. The splicing baffle includes a first rotating mounting plate and a second rotating mounting plate symmetrically mounted on a sliding adjusting block. The side of the first rotating mounting plate is provided with a first splicing protrusion, and the side of the second rotating mounting plate is provided with a first splicing groove. Multiple splicing blocks are installed between the first rotating mounting plate and the second rotating mounting plate. One side of the splicing block is provided with a second splicing protrusion, and the end of the splicing block away from the second splicing protrusion is provided with a second splicing groove.

[0006] Preferably, the adjustment frame includes multiple right-angle frames, each with a first limiting slide rail at both ends, and a telescopic adjustment rod installed between the first limiting slide rails. Both the right-angle frames and the telescopic adjustment rods have multiple fixing holes, and each right-angle frame has multiple first positioning holes.

[0007] Preferably, the telescopic support frame includes multiple transverse telescopic rods extending to both ends. The bottom of the transverse telescopic rod is provided with a first support leg, one end of the transverse telescopic rod is provided with a second limiting slide rail, and the transverse telescopic rod is also provided with a second positioning mounting hole. The transverse telescopic rod is installed on the second limiting slide rail, a transverse connecting rod is installed on the second limiting slide rail, and a second support leg is installed below the transverse connecting rod.

[0008] Preferably, the fixed enclosure and the movable enclosure have the same structure. The fixed enclosure includes multiple limiting mounting plates installed on the right-angle frame. The limiting mounting plates are equipped with third positioning mounting holes. The side of the limiting mounting plates is provided with a third limiting slide rail. The third limiting slide rail is equipped with a first connecting plate.

[0009] Preferably, the elastic booster includes a mounting sleeve mounted on a fixed guide plate, a telescopic push rod installed inside the mounting sleeve, and a first return spring installed between the telescopic push rod and the mounting sleeve.

[0010] Preferably, the pneumatic flipping mechanism includes a pneumatic arc-shaped rail mounted on the second splicing protrusion. The side of the pneumatic arc-shaped rail is provided with an air inlet. A pneumatic slider is installed inside the pneumatic arc-shaped rail. An arc-shaped push rod is installed on the pneumatic slider. The end of the arc-shaped push rod away from the pneumatic slider is connected to the splicing baffle. A second return spring is also installed on the arc-shaped push rod. One end of the second return spring abuts against the pneumatic slider, and the end of the second return spring away from the pneumatic slider abuts against the pneumatic arc-shaped rail.

[0011] The advantages of this invention compared to the prior art are: The pneumatic shielding plates are fully opened using pneumatic technology. Then, the pneumatic traction device is driven to rotate and open the movable enclosure. Once both the movable enclosure and the pneumatic shielding plates are open, workers use forklifts or other lifting equipment to place the double anode blocks onto the adaptive limit seats. The fixed enclosure effectively guides the placement of the double anode blocks. After the double anode blocks are placed in the designated position on the adaptive limit seats, the forklift detaches from the double anode blocks. Workers then use the pneumatic traction device to reset the movable enclosure. After resetting, the movable enclosure, in conjunction with the fixed enclosure, wraps around the bottom edge of the double anode blocks. After the edges of the double anode blocks are wrapped, the pneumatic shielding plates reset. During reset, the pneumatic shielding plates rotate and retract, causing their edges to contact the outside of the double anode blocks, effectively shielding the surrounding sprayed surface and improving spraying quality and efficiency.

Detailed Implementation

[0024] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0025] See Figures 1 to 11As shown, a pneumatic control device for an aluminum electrolysis double anode support includes an adaptive pneumatic shielding seat for limiting and shielding the double anode blocks. The adaptive pneumatic shielding seat includes an adaptive limiting seat 1 with adaptive adjustable size. Multiple fixed enclosure plates 2 are installed on the adaptive limiting seat 1, and the fixed enclosure plates 2 are spliced ​​together. A movable enclosure plate 3 is also installed on the adaptive limiting seat 1. A pneumatic traction device 4 is installed between the movable enclosure plate 3 and the fixed enclosure plate 2. Pneumatic shielding plates 5 are installed on both the movable enclosure plate 3 and the fixed enclosure plate 2.

[0026] When workers need to spray paint the surface of the double anode blocks, they first adjust the size of the adaptive limit seat 1 according to the size of the double anode blocks. During the adjustment, the fixed enclosure 2, movable enclosure 3, and pneumatic shielding plate 5 will adjust and move accordingly to facilitate the adaptation of the size of each component to the size of the double anode blocks. After the size of each component is adjusted, workers can affix spraying stickers to the outside of the pneumatic shielding plate 5. The pneumatic shielding plate 5 is then fully opened pneumatically. The pneumatic traction device 4 is then driven pneumatically to rotate and open the movable enclosure 3. After both the movable enclosure 3 and the pneumatic shielding plate 5 are open, workers can then spray paint onto the surface of the double anode blocks. Using forklifts or other lifting equipment, the double anode blocks are placed onto the adaptive limit seat 1. The fixed enclosure 2 effectively guides the placement of the double anode blocks. After the double anode blocks are placed in the designated position on the adaptive limit seat 1, the forklift will detach from the double anode blocks. The operator then uses the pneumatic traction device 4 to reset the movable enclosure 3. After the movable enclosure 3 is reset, it will work with the fixed enclosure 2 to wrap around the bottom edge of the double anode blocks. After the edges of the double anode blocks are wrapped, the pneumatic shielding plate 5 is reset. When the pneumatic shielding plate 5 is reset, it will rotate and retract, so that the edge of the pneumatic shielding plate 5 contacts the outside of the double anode blocks, effectively shielding the sprayed surface around the double anode blocks, which can effectively improve the spraying quality and spraying efficiency.

[0027] See Figures 1 to 2 As shown, the adaptive limit seat 1 includes an adjustment frame 11 that adaptively adjusts its size. A fixed support leg 12 is installed at the bottom of the adjustment frame 11, and multiple telescopic support frames 13 are also installed inside the adjustment frame 11.

[0028] The fixed support leg 12 is used to limit the support adjustment frame 11. During the spraying production, different sizes of double anode blocks are encountered. Therefore, when it is necessary to change to spray different models of double anode blocks, the size will also change accordingly. Therefore, whenever it is necessary to produce double anode blocks of different sizes, multiple workers can stretch the adjustment frame 11 laterally and longitudinally. When stretching the adjustment frame 11 laterally and longitudinally, the size of the adjustment frame 11 will be matched with the adjustment frame 11. During the adjustment of the adjustment frame 11, the telescopic support frame 13 will stretch and adjust accordingly, which can effectively improve the applicability of use.

[0029] See Figure 2 and Figure 5 As shown, the adjustment frame 11 includes multiple right-angle frames 111. Both ends of the right-angle frames 111 are provided with first limiting slide rails. Telescopic adjustment rods 112 are installed between the first limiting slide rails. Multiple fixing mounting holes 113 are provided on the right-angle frames 111 and the telescopic adjustment rods 112. Multiple first positioning mounting holes 114 are provided on the right-angle frames 111.

[0030] When the size of the adjustment frame 11 needs to be adjusted, the operator can first stretch the right-angle frame 111 laterally. When the right-angle frame 111 is stretched laterally, it will drive the telescopic adjustment rod 112 to move synchronously. After the right-angle frame 111 is adjusted laterally, the operator can then fix the telescopic adjustment rod 112 by passing bolts through the first positioning mounting hole 114. After the telescopic adjustment rod 112 is fixed, the operator can then stretch the right-angle frame 111 longitudinally. When the right-angle frame 111 is adjusted longitudinally, the telescopic adjustment rod 112 will stretch. After the right-angle frame 111 is adjusted longitudinally, the operator can then fix the telescopic adjustment rod 112 by passing bolts through the first positioning mounting hole 114. The fixing mounting holes 113 on the right-angle frame 111 and the telescopic adjustment rod 112 are used to install the telescopic support frame 13.

[0031] See Figure 2 and Figure 6 As shown, the telescopic support frame 13 includes multiple transverse telescopic rods 131 extending to both ends. The bottom of the transverse telescopic rod 131 is provided with a first support leg 132. One end of the transverse telescopic rod 131 is provided with a second limiting slide rail. The transverse telescopic rod 131 is also provided with a second positioning mounting hole 133. The transverse telescopic rod 131 is mounted on the second limiting slide rail. A transverse connecting rod 134 is mounted on the second limiting slide rail. A second support leg 135 is mounted below the transverse connecting rod 134.

[0032] When the adjustment frame 11 is stretched and adjusted, the transverse telescopic rod 131 of the telescopic support frame 13 will stretch and move accordingly. When the transverse telescopic rod 131 is stretched and moved, the transverse connecting rod 134 will slide in the second limit slide rail. The transverse connecting rod 134 is used to connect the transverse telescopic rod 131 stretched to both ends. After the transverse telescopic rod 131 is stretched and adjusted, the staff will fix the transverse connecting rod 134 by passing the fixing bolt through the second positioning mounting hole 133. The first support leg 132 is used to support the transverse telescopic rod 131, and the second support leg 135 is used to support the transverse connecting rod 134. The transverse telescopic rod 131 and the transverse connecting rod 134 are used to support the double anode block.

[0033] See Figure 2 and Figure 7As shown, the fixed enclosure 2 and the movable enclosure 3 have the same structure. The fixed enclosure 2 includes multiple limiting mounting plates 21 installed on the right angle frame 111. The limiting mounting plates 21 are equipped with third positioning mounting holes 211. The side of the limiting mounting plates 21 is provided with a third limiting slide rail. The third limiting slide rail is equipped with a first connecting plate 22.

[0034] When the right-angle bracket 111 of the adaptive limit seat 1 is pulled and moved, it will drive the limit mounting plate 21 to move synchronously. When the movable enclosure 3 moves, it will drive the first connecting plate 22 to slide synchronously in the third limit slide rail. After the right-angle bracket 111 is adjusted, the staff will fix the first connecting plate 22 by passing bolts through the third positioning mounting hole 211. After the limit mounting plate 21 and the first connecting plate 22 are installed, when the double anode block is placed on the adaptive limit seat 1 by a forklift, the limit mounting plate 21 and the first connecting plate 22 can effectively guide the placement of the double anode block, improving the placement speed and accuracy of the double anode block.

[0035] See Figure 1 , Figure 2 and Figure 3 As shown, the pneumatic traction device 4 includes a fixed guide plate 41 mounted on the fixed enclosure 2, several guide wheels 411 mounted on the fixed guide plate 41, a long shaft cylinder 43 mounted on the side of the fixed enclosure 2, the pneumatic traction device 4 also includes a second connecting plate 42 mounted on the movable enclosure 3, a connecting rope 45 mounted on the second connecting plate 42, the end of the connecting rope 45 away from the second connecting plate 42 passes through the guide wheels 411 and connects to the output end of the long shaft cylinder 43, and an elastic booster 44 is also mounted on the fixed guide plate 41.

[0036] When the movable enclosure 3 needs to be opened, the long-shaft cylinder 43 drives the connecting rope 45 to extend outward. When the connecting rope 45 extends outward, the guide wheel 411 of the fixed guide plate 41 can effectively reduce the friction. When the connecting rope 45 extends outward, the elastic booster 44 will push the movable enclosure 3 to reverse downward. When the movable enclosure 3 flips downward, the fixed enclosure 2 and the movable enclosure 3 can be separated. When the long-shaft cylinder 43 retracts and moves, it will drive the movable enclosure 3 to reset.

[0037] See Figure 3 and Figure 4 As shown, the elastic booster 44 includes a mounting sleeve 441 mounted on a fixed guide plate 41. A telescopic pusher 442 is installed inside the mounting sleeve 441, and a first return spring 443 is installed between the telescopic pusher 442 and the mounting sleeve 441.

[0038] When the movable enclosure 3 and the fixed enclosure 2 are in contact, the telescopic push column 442 will be compressed and retracted inside the mounting sleeve 441. The first return spring 443 will be compressed, and the connecting pull rope 45 will be extended outward through the long shaft cylinder 43. The connecting pull rope 45 will then cancel the pulling force of the movable enclosure 3. After the movable enclosure 3 loses its pulling force, the first return spring 443 will push the telescopic push column 442 to extend outward. When the telescopic push column 442 extends outward, it will push the movable enclosure 3 to flip open quickly, effectively preventing the connecting pull rope 45 from failing to rotate and open automatically after the pulling force of the movable enclosure 3 is canceled, thus effectively improving the smoothness of opening.

[0039] See Figure 7 and Figure 8 As shown, the pneumatic shielding plate 5 includes several adjustable mounting guide posts 52, a sliding adjusting block 53 is mounted on the adjustable mounting guide post 52, a splicing baffle 51 is mounted on the sliding adjusting block 53, and at least one pneumatic flipping mechanism 54 is mounted on the sliding adjusting block 53. The driving end of the pneumatic flipping mechanism 54 is connected to the splicing baffle 51.

[0040] When the fixed enclosure 2 and the movable enclosure 3 are adjusted in size, the adjusting mounting guide column 52 will move synchronously. The adjusting mounting guide column 52 will then move the sliding adjusting block 53, the pneumatic tilting mechanism 54, and the splicing baffle 51 synchronously. After the splicing baffle 51 is adjusted, workers can apply a layer of sprayed sticker to its outer wall. When double anode blocks need to be placed, workers use an erecting device to supply air pressure to the pneumatic tilting mechanism 54, causing the pneumatic tilting mechanism 54 to adjust the angle of the splicing baffle 51. Then, the pneumatic traction device 4 is driven pneumatically, rotating and opening the movable enclosure 3. After both the movable enclosure 3 and the pneumatic shielding plate 5 are opened, workers can then... The double anode blocks are placed onto the adaptive limit seat 1 using lifting equipment such as forklifts. The fixed enclosure 2 effectively guides the placement of the double anode blocks. After the double anode blocks are placed in the designated position on the adaptive limit seat 1, the forklift will detach from the double anode blocks. The operator then uses the pneumatic traction device 4 to reset the movable enclosure 3. After the movable enclosure 3 is reset, it will work with the fixed enclosure 2 to wrap around the bottom edge of the double anode blocks. After the edges of the double anode blocks are wrapped, the air pressure supplied to the pneumatic tilting mechanism 54 will stop. The pneumatic tilting mechanism 54 will then drive the splicing baffle 51 to reset and move. When the splicing baffle 51 is reset, it will come into contact with the outside of the double anode blocks, effectively shielding the sprayed surface around the double anode blocks and effectively improving the spraying quality.

[0041] See Figure 8 and Figure 9As shown, the splicing baffle 51 includes a first rotating mounting plate 511 and a second rotating mounting plate 513 symmetrically mounted on the sliding adjusting block 53. The side of the first rotating mounting plate 511 is provided with a first splicing protrusion 512, and the side of the second rotating mounting plate 513 is provided with a first splicing groove 514. A plurality of splicing blocks 515 are installed between the first rotating mounting plate 511 and the second rotating mounting plate 513. A second splicing protrusion 516 is provided on one side of the splicing block 515, and a second splicing groove 517 is provided at the end of the splicing block 515 away from the second splicing protrusion 516.

[0042] The splicing baffle 51 is formed by splicing together a first rotating mounting plate 511, a second rotating mounting plate 513, and multiple splicing blocks 515. When adjusting the size of the fixed enclosure 2 and the movable enclosure 3, the workers will remove multiple splicing blocks 515 in advance to allow the first rotating mounting plate 511 and the second rotating mounting plate 513 to move and adjust. After the fixed enclosure 2 and the movable enclosure 3 are adjusted, the workers will select an appropriate number of splicing blocks 515 according to the distance between the first rotating mounting plate 511 and the second rotating mounting plate 513, and then install the splicing blocks 515 between the first rotating mounting plate 511 and the second rotating mounting plate 513. The first splicing groove 514 and the first splicing protrusion 512 fit together. The first splicing groove 514 and the second splicing groove 517 are the same size. The first splicing protrusion 512 and the second splicing protrusion 516 are the same size. The first rotating mounting plate 511, the second rotating mounting plate 513, and the multiple splicing blocks 515 are then spliced ​​together.

[0043] See Figure 8 , Figure 10 and Figure 11 As shown, the pneumatic tilting mechanism 54 includes a pneumatic arc-shaped rail 541 mounted on the second splicing protrusion 516. The side of the pneumatic arc-shaped rail 541 is provided with an air inlet 542. A pneumatic slider 543 is installed inside the pneumatic arc-shaped rail 541. An arc-shaped push rod 544 is installed on the pneumatic slider 543. The end of the arc-shaped push rod 544 away from the pneumatic slider 543 is connected to the splicing baffle 51. A second return spring 545 is also installed on the arc-shaped push rod 544. One end of the second return spring 545 abuts against the pneumatic slider 543, and the end of the second return spring 545 away from the pneumatic slider 543 abuts against the pneumatic arc-shaped rail 541.

[0044] When the splicing baffle 51 needs to be rotated and adjusted, air pressure is supplied to the air inlet 542 of the pneumatic arc-shaped rail 541 through the air supply pipe. When the air pressure enters the pneumatic arc-shaped rail 541, it pushes the pneumatic slider 543 to move along the pneumatic arc-shaped rail 541. When the pneumatic slider 543 moves in an arc, it squeezes the second return spring 545. When the pneumatic slider 543 moves, it also drives the arc-shaped push rod 544 to move in an arc. When the arc-shaped push rod 544 moves, it pushes the splicing baffle 51 to rotate. When the air supply pipe stops supplying air, the second return spring 545 pushes and squeezes the pneumatic slider 543 to reset. When the pneumatic slider 543 resets, it drives the splicing baffle 51 to reset, effectively realizing the driving flipping motion.

[0045] Specific working principle: When workers need to spray paint the surface of the double anode blocks, they first adjust the size of the adaptive limit seat 1 according to the size of the double anode blocks. During the adjustment, the fixed enclosure 2, the movable enclosure 3, and the pneumatic shielding plate 5 will adjust and move accordingly to facilitate the adaptation of the size of each component to the size of the double anode blocks. After the size of each component is adjusted, workers can affix spraying stickers to the outside of the pneumatic shielding plate 5. The pneumatic shielding plate 5 is then fully opened using pneumatic technology. Then, the pneumatic traction device 4 is driven pneumatically, which rotates and opens the movable enclosure 3, thus opening both the movable enclosure 3 and the pneumatic shielding plate 5. Afterwards, the staff will use a forklift or other lifting equipment to place the double anode block onto the adaptive limit seat 1. The fixed enclosure 2 can effectively guide the placement of the double anode block. After the double anode block is placed in the designated position on the adaptive limit seat 1, the forklift will detach from the double anode block. The staff will then use the pneumatic traction device 4 to reset the movable enclosure 3. After the movable enclosure 3 is reset, it will cooperate with the fixed enclosure 2 to wrap around the bottom edge of the double anode block. After the edge of the double anode block is wrapped, the pneumatic shielding plate 5 is reset. When the pneumatic shielding plate 5 is reset, it will rotate and retract, so that the edge of the pneumatic shielding plate 5 is in contact with the outside of the double anode block, effectively shielding the sprayed surface around the double anode block.
