Description

Technical Field

[0001] The present application relates to the technical field of electrolytic aluminum equipment manufacturing, and in particular to a pressurized gas supply system. Background Art

[0002] The busbar lifting frame is one of the key equipment in the electrolytic aluminum production workshop. During the electrolytic aluminum production process, as the anode carbon blocks continue to burn out, the height of several groups of anode guide rods (connected to the anode carbon blocks) fixed on the busbar with small box clamps continues to decrease as the busbar moves downward. This adjustment is completed by the anode lifting mechanism. When the busbar moves to the process downline position, the busbar lifting frame is required to clamp and fix the anode guide rods, and then the anode lifting mechanism is used to lift the busbar to the process upline. When adjusting the relative position of the anode guide rod on the busbar, firstly, the corresponding anode guide rod is clamped by several groups of anode clamp mechanisms on the busbar lifting frame to prevent the anode carbon block from falling; then, the several groups of small box clamps clamped on the busbar are successively loosened by the pneumatic actuator (small box clamp tensioning device) arranged on the sliding frame of the busbar lifting frame, and the anode guide rod and the anode carbon block can be hung there intact; at this time, the busbar is lifted to the process line by the anode lifting mechanism, and then the small box clamp tensioning device is used to tighten the small box clamps in turn, and the anode guide rod is fixed to the busbar again; finally, the anode guide rod clamp mechanism is loosened, and the busbar lifting frame can be moved to the next electrolytic cell to accept a new task.

[0003] The traditional busbar lifting frame drives the anode guide rod clamp mechanism to perform clamping and releasing actions through the clamping cylinder. Specifically, when the clamping cylinder is inflated, the anode guide rod clamp mechanism performs the releasing action; when the clamping cylinder is de-aired, the anode guide rod clamp mechanism performs the clamping action. Since there will be a certain pressure fluctuation when the air compressor supplies air to the clamping cylinder, the anode guide rod clamp mechanism takes a long time to perform the releasing action or even fails to perform the releasing action, causing the busbar lifting frame to stay on the electrolytic cell for a long time and unable to move to the next electrolytic cell operation, affecting the busbar lifting operation.

[0025] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] The traditional busbar lifting frame drives the anode guide rod clamp mechanism to perform clamping and releasing actions through the clamping cylinder. Specifically, when the clamping cylinder is inflated, the anode guide rod clamp mechanism performs the releasing action; when the clamping cylinder is de-aired, the anode guide rod clamp mechanism performs the clamping action. Since there will be a certain pressure fluctuation when the air compressor supplies air to the clamping cylinder, the anode guide rod clamp mechanism takes a long time to perform the releasing action or even fails to perform the releasing action, causing the busbar lifting frame to stay on the electrolytic cell for a long time and unable to move to the next electrolytic cell operation, affecting the busbar lifting operation.

[0028] In view of this, the present application proposes a pressurized air supply system. Figures 1 to 6 This is a schematic diagram of the structure of the pressurized air supply system of the present application.

[0029] See also Figure 1The present application proposes a pressurized air supply system 100, which includes an air compressor 1, a first air storage tank 2, a three-way pipe, a first main control valve 4121, a second main control valve 4124 and a control module. The three-way pipe has an air outlet end 412, a first air inlet end 23 and a second air inlet end 21. The air outlet end 412 is connected to a cylinder 3 that drives and connects an anode guide rod clamp mechanism. The first air inlet end 23 is connected to the air compressor 1, and the second air inlet end 21 is connected to the first air storage tank 2. The first main control valve 4121 is provided at the second air inlet end 21 for controlling the disconnection of the second air inlet end 21. The second main control valve 4124 is provided at the air outlet end 412. The air end 412 is used to control the disconnection and connection of the air outlet end 412. The control module is respectively connected to the first main control valve 4121 and the second main control valve 4124 by signals, wherein the control module is used to send a first working signal to the first main control valve 4121 to open the second air inlet end 21, so that the air compressor 1 can inflate and pressurize the first air storage tank 2. The control module is also used to simultaneously send a first working signal to the first main control valve 4121 and a second working signal to the second main control valve 4124 to open the second air inlet end 21 and the air outlet end 412, so that the air compressor 1 and the first air storage tank 2 can synchronously supply air to the cylinder 3.

[0030] In the technical solution provided in the present application, before supplying air to the cylinder 3, compressed air can be transported to the first air tank 2 through the air compressor 1. The amount of compressed air stored in the first air tank 2 must at least be enough to provide the cylinder 3 with a sufficient air pressure to open the clamp together with the air compressor 1. Of course, the volume of the first air tank 2 must be large enough to store enough compressed air. When supplying air to the cylinder 3, the first main control valve 4121 and the second main control valve 4124 open the second air inlet end 21 and the air outlet end 412 together. The compressed air generated by the air compressor 1 and the compressed air in the first air tank 2 pass through the air outlet end 412 together. Since the air pressure is caused by the impact force of gas molecules on the container wall, when more gas molecules are compressed into the same space, the number of impacts on the container wall will increase, thereby increasing the air pressure. The compressed air generated by the air compressor 1 and the compressed air in the first air tank 2 enter the air outlet end 412, that is, more compressed air enters the air outlet end 412, thereby increasing the air supply pressure.

[0031] It should be noted that the first main control valve 4121 and the second main control valve 4124 can be replaced by a connecting valve, the cylinder 3 can be a clamping cylinder, the anode guide rod clamp mechanism can include a clamp, the clamping cylinder can open and close the clamp, the clamp can be used to clamp the anode guide rod, and the clamping cylinder needs to be provided with gas with sufficient air pressure to enable the clamp to loosen the anode guide rod, wherein the control module can control the start and stop of the air compressor 1.

[0032] In order to speed up the opening speed of the clamp, shorten the time of opening the clamp, make the clamp open faster, and improve work efficiency, a large amount of compressed air can be stored in a first air storage tank 2 with a large volume, so as to provide sufficient compressed air to the cylinder 3 together with the air compressor 1. Of course, in order to further save the occupied space of the site, the clamp can also be quickly opened with a first air storage tank 2 with a small volume. In an embodiment of the present application, the booster air supply system 100 also includes a pressurizing part, which includes a first connecting pipe 41, a second connecting pipe 52 and a booster pump 4. The first connecting pipe 41 is connected to the air outlet end 412, and the second connecting pipe 52 is connected to the cylinder 3. The booster pump 4 is connected to the first connecting pipe 41 and the second connecting pipe 52 and is integrally arranged. The booster pump 4 includes a gas booster pump 4 or an air booster pump 4, which can be used to increase the pressure of the gas. The control module can control the start and stop of the booster pump 4, and the compressed air flowing out of the air outlet end 412 will pass through the first connecting pipe 41, the second connecting pipe 52 and the booster pump 4. The pipe 41 enters the booster pump 4, and the control module can control the start of the booster pump 4. The booster pump 4 pressurizes the compressed air to make the compressed air have a higher pressure, and then transmits the compressed air to the cylinder 3 through the second connecting pipe 52 to open the clamp more quickly. Among them, the first main control valve 4121 can be closed, and the second main control valve 4124 can be opened. The compressed air is only generated by the air compressor 1 and transmitted to the booster pump 4. Of course, the first main control valve 4121 and the second main control valve 4124 can also be opened at the same time, so that the air in the first air storage tank 2 and the compressed air generated by the air compressor 1 enter the booster pump 4 for pressurization together, which can reduce the working pressure of the booster pump 4. The first connecting pipe 41 and the second connecting pipe 52 are both integrated with the booster pump 4, which can reduce the probability of gas leakage due to poor sealing due to the use of external pipes, thereby improving the sealing between the first connecting pipe 41 and the second connecting pipe 52 and the booster pump 4.

[0033] In order to prevent the clamp from being damaged by being too open when the boost pump 4 over-pressurizes the compressed gas received by the cylinder 3 so that the pressure is too high, in the embodiment of the present application, the boost air supply system 100 also includes a pressure relief part, which includes a pressure relief pipe 22, an air pressure sensor 522 and a two-position two-way valve 521. The pressure relief pipe 22 is provided with a first one-way valve 221. The pressure relief pipe 22 has a recovery end and an air supply end. The recovery end is connected to the first air storage tank 2, and the air supply end is connected to the second connecting pipe 52. The air pressure sensor 522 is arranged in the second connecting pipe 52. The air pressure sensor 522 is located between the boost pump 4 and the air supply end. The two-position two-way valve 521 is arranged in the second connecting pipe 52, wherein the control module is electrically connected to the air pressure sensor 522 and the two-position two-way valve 521, and the air pressure sensor 52 2 is used to send a pressure signal to the control module, and the control module sends a third working signal to the two-position two-way valve 521 according to the pressure signal, so that the two-position two-way valve 521 switches the boost pump 4 to be connected with one of the pressure relief pipe 22 and the cylinder 3 according to the third working signal. When the air pressure sensor 522 detects that the air pressure of the compressed air output from the boost pump 4 exceeds the preset air pressure, it will send a pressure signal to the control module. The control module will analyze whether the air pressure of the compressed air output from the boost pump 4 exceeds the preset air pressure through the pressure signal, and send a third working signal when the preset air pressure is exceeded to the two-position two-way valve 521, thereby making the two-position two-way valve 521 block the connection between the boost pump 4 and the cylinder 3 according to the third working signal, so that the boost pump 4 is connected with the air supply end, and the air supply in the boost pump 4 is A part of the compressed air discharged will enter the first air storage tank 2 through the pressure relief pipe 22 for recycling, which can not only reduce the pressure of the compressed air entering the cylinder 3, but also recycle the discharged compressed air. When the pressure of the compressed air output by the boost pump 4 drops to a preset pressure value, the pressure sensor 522 transmits a pressure signal to the control module. The control module will analyze whether the pressure of the compressed air output from the boost pump 4 exceeds the preset pressure through the pressure signal, and send a third working signal when the preset pressure is reached to the two-position two-way valve 521, thereby making the two-position two-way valve 521 block the connection between the boost pump 4 and the pressure relief pipe 22 according to the third working signal, and restore the connection between the boost pump 4 and the cylinder 3. It should be pointed out that the third working signal can make the two-position two-way valve 521 performs two actions, namely, blocking the connection between the boosting pump 4 and the cylinder 3 and blocking the connection between the boosting pump 4 and the pressure relief pipe 22, wherein the preset air pressure is the lowest air pressure that does not damage the fixture, and the first one-way valve 221 only allows the compressed air output by the boosting pump 4 to enter the first air tank 2 through the pressure relief pipe 22, and does not allow the compressed air in the first air tank 2 to enter the second connecting pipe 52 through the hydraulic pipe. The two-position two-way valve 521 can open one channel when one channel is closed, or close another channel while one channel is opened. In another embodiment, two pressure relief ball valves can be used instead of the two-position two-way valve 521, and one pressure relief ball valve can be closed and the other pressure relief ball valve can be opened to achieve the pressure relief of the compressed air output by the boosting pump 4.

[0034] Since the booster pump 4 will generate a large shake when working, the booster pump 4 will also cause the first connecting pipe 41 and the second connecting pipe 52 connected thereto to shake when shaking, while the second connecting pipe 52 is directly connected to the booster pump 4 and the cylinder 3, and the possibility of affecting the sealing due to shaking is small. The first connecting pipe 41 is also connected to the air outlet end 412 connected to the three-way pipe. When the booster pump 4 is working, the connection between the first connecting pipe 41 and the air outlet end 412 will also shake, which will increase the possibility of loosening the connection and causing a gap. In order to reduce the influence of shaking on the sealing of the first connecting pipe 41 and the air outlet end 412, in the embodiment of the present application, please refer to Figure 5 The outer peripheral wall of the three-way pipe near the gas outlet end 412 is protruding outwardly with an annular groove 4123 surrounding the gas outlet end 412, and a sealant 4122 is provided in the annular groove 4123. The inner diameter of the first connecting pipe 41 is larger than the inner diameter of the gas outlet end 412, and the first connecting pipe 41 is threadedly connected with the gas outlet end 412. When the first connecting pipe 41 is connected to the gas outlet end 412, the internal thread of the first connecting pipe 41 can be screwed into the corresponding external thread of the three-way pipe at the gas outlet end 412, and the first connecting pipe 41 and the gas outlet end 412 can be meshed by the internal and external threads. 12 is sealed, and after the first connecting pipe 41 enters the annular groove 4123, the sealant 4122 will be immersed in the sealant 4122, and the sealant 4122 will further increase the sealing effect of the connection between the first connecting pipe 41 and the air outlet end 412, wherein the sealant 4122 is a viscous liquid with low fluidity, so the air outlet end 412 and the first connecting pipe 41 can be placed in a horizontal direction first and then threadedly connected. Of course, the air outlet end 412 of the tee can also be placed in a vertical direction with the notch of the annular groove 4123 facing upwards, and then threadedly connected.

[0035] Since the pressure of the compressed air output by the boost pump 4 will fluctuate to a certain extent, it will affect the opening speed of the clamp. In order to reduce the impact on the opening speed of the clamp and make the clamp open more stably, in the embodiment of the present application, the boost air supply system 100 also includes a voltage stabilizing part, which includes a second air tank 5, an air supply pipe 31 and a second one-way valve 51. The second air tank 5 is connected to the second connecting pipe 52 and is located between the air supply end and the cylinder 3. The air supply pipe 31 is provided with a third main control valve 32 electrically connected to the control module. The two ends of the air supply pipe 31 are respectively connected to the second air tank 5 and the cylinder 3. The second one-way valve 51 is provided in the second connecting pipe 52 and is located between the air supply end and the second air tank 5. Among them, the third main control valve 32 is used to control the disconnection of the air supply pipe 31, and the control module The block is electrically connected to the third main control valve 32, which is used to send the first signal and the second signal to the third main control valve 32 to close and open the air pipe 31, so as to inflate and pressurize the cylinder 3. The compressed air output from the boost pump 4 will enter the second air tank 5 through the second one-way valve 51. The control module sends the first signal to the third main control valve 32 to close the third main control valve 32 and store the pressurized compressed air in the second air tank 5. When it is necessary to supply air to the cylinder 3, the control module sends the second signal to the third main control valve 32 to open the third main control valve 32. The pressurized compressed air in the second air tank 5 will enter the cylinder 3 through the air pipe 31. In this way, the pressure fluctuation of the compressed air can be reduced, so that the clamp can be opened stably and quickly.

[0036] Since the booster pump 4 will generate a large shake when working, in order to reduce the shake of the booster pump 4 and keep the booster pump 4 stable when working, in the embodiment of the present application, please refer to Figures 2 to 4The boost air supply system 100 also includes an anti-sway structure, which includes a fixed seat 7, a limiting frame, a mounting seat 72, a movable block 8, a movable rod 712 and an interlaced portion 73. The limiting frame includes an abutment plate 711 and two limiting plates 71. The two ends of the abutment plate 711 are respectively connected to the two limiting plates 71. The two limiting plates 71 are rotatably installed on the fixed seat 7. The mounting seat 72 is fixedly connected to the fixed seat 7 and is arranged away from the boost pump 4. The mounting seat 72 is provided with a groove 721 and a plurality of limiting holes 74 arranged at intervals along the direction in which the groove 721 extends. The movable block 8 is movably arranged in the groove 721. The movable block 8 is provided with a through hole. The two ends of the movable rod 712 are respectively hinged to one of the two limiting plates 71. The locking cam 720 is fixed to the locking cam 721 and the locking cam 730 is fixed to the locking cam 721. The locking cam 720 is fixed to the locking cam 721 and the locking cam 730 is fixed to the locking cam 721. When the abutment plate 711 abuts against the top of the booster pump 4, the insertion portion 73 is successively inserted into the limiting hole 74 and the through hole, and the movable block 8 can be fixed in the groove 721. When the booster pump 4 is about to shake, since its top is pressed by the abutment plate 711, the movable block 8 is also stationary, and the booster pump 4 cannot move in the up and down directions, and the abutment plate 711 will apply friction resistance in the horizontal direction to the top of the booster pump 4, further reducing the horizontal range of movement of the booster pump 4, thereby reducing the shaking of the first connecting pipe 41 and the second connecting pipe 52 connected thereto, wherein a plurality of limiting holes 74 can fix the abutment plate 711 at different heights to adapt to booster pumps 4 of different heights, and the insertion portion 73 can It includes a latch and may also include a bolt. The bolt passes through the limiting hole 74 and is threadedly connected to the mounting seat 72, so that the movable block 8 can be more firmly positioned in the groove 721. The mounting seat 72 is set away from the boost pump 4. Specifically, when the fixed seat 7 is standing, the mounting seat 72 is below the rotation center of the limiting plate 71, which can prevent the mounting seat 72 from being in the rotation stroke of the limiting plate 71 and blocking the rotation of the limiting plate 71, so that the abutment plate 711 can smoothly abut against the top of the boost pump 4 at different heights. It can be understood that two mounting seats 72, movable blocks 8 and movable rods 712 can be set, and they are respectively arranged on both sides of the fixed seat 7 to make the rotation of the limiting frame more stable.

[0037] Since only a small part of the abutment plate 711 will directly contact the top of the boost pump 4 when it abuts against the top of the boost pump 4, the edge of the abutment plate 711 may abut against the top of the boost pump 4, forming a linear contact with the boost pump 4, and the contact area is small and cannot be adjusted. In order to increase the abutment area between the abutment plate 711 and the boost pump 4, in an embodiment of the present application, the two ends of the abutment plate 711 are respectively rotatably installed on the two limiting plates 71, so that when the abutment plate 711 is about to contact the top of the boost pump 4, the abutment plate 711 can be rotated and the outer surface of the abutment plate 711 with the largest area can contact the top of the boost pump 4, thereby increasing the limiting effect of the abutment plate 711 on the boost pump 4.

[0038] In order to increase the limiting effect of the abutment plate 711 on the boost pump 4 in the horizontal direction, in an embodiment of the present application, a friction pad is provided on the outer surface of the abutment plate 711, and the material of the friction pad is natural rubber material. By providing the friction pad, the friction resistance of the abutment plate 711 to the top of the boost pump 4 in the horizontal direction can be increased when the boost pump 4 shakes, thereby further reducing the shaking range of the boost pump 4 in the horizontal direction. The friction pad is made of natural rubber, and can have a larger friction coefficient when it contacts the metal boost pump 4, thereby further enhancing the limiting effect of the abutment plate 711.

The placement seat 6 is arranged on the top of the support seat 62 and is provided with a receiving groove 63. The placement seat 6 is made of elastic material. There are two support structures to reduce the shaking of the first connecting pipe 41 and the second connecting pipe 52 respectively. When installing the first connecting pipe 41 and the second connecting pipe 52, the first connecting pipe 41 and the second connecting pipe 52 can be placed in the corresponding receiving groove 63 respectively. Since the material of the placement seat 6 is elastic material, when the notch of the receiving groove 63 is small, the first connecting pipe 41 or the second connecting pipe When inserted, 52 will push the two side walls of the accommodating groove 63, and the two side walls of the accommodating groove 63 will undergo elastic deformation and bend in the direction away from each other, so that the first connecting tube 41 or the second connecting tube 52 enters the corresponding accommodating groove 63, and then the two side walls of the accommodating groove 63 restore to their original state under the action of their own elastic force and squeeze the first connecting tube 41 and the second connecting tube 52 to limit the first connecting tube 41 and the second connecting tube 52 in the horizontal direction, wherein the accommodating groove 63 can be an arc groove adapted to the first connecting tube 41 and the second connecting tube 52, or it can be a groove of other shapes.

[0040] In order to limit the first connecting tube 41 and the second connecting tube 52 in the up and down directions, in the embodiment of the present application, please refer to Figure 6The supporting structure also includes a cover plate 61 and a fixing bolt. The cover plate 61 is rotatably installed on the placement seat 6. The cover plate 61 is provided with a positioning hole. The fixing bolt is passed through the positioning hole so that when the cover plate 61 blocks the notch of the receiving groove 63, the cover plate 61 can be fixed to the placement seat 6. When the first connecting tube 41 and the second connecting tube 52 are placed in the corresponding receiving groove 63, the cover plate 61 is rotated so that the cover plate 61 blocks the notch of the first connecting tube 41 and the receiving groove 63 or blocks the notch of the second connecting tube 52 and the receiving groove 63, and the cover plate 61 is fixed to the placement seat 6 by the fixing bolt to limit the first connecting tube 41 and the second connecting tube 52 in the up and down directions, further reduce the shaking of the first connecting tube 41 and the second connecting tube 52, and avoid the first connecting tube 41 and the second connecting tube 52 from destroying the sealing of the connection with other components due to shaking, wherein the cover plate 61 can also be arranged in an arc shape to adapt to the first connecting tube 41 and the second connecting tube 52, and the cover plate 61 can also be hinged to the placement seat 6.
