[0032] In order to make the purpose, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to 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.

[0033] In the technical field of aluminum electrolysis industry, a full-automatic busbar lifting frame is correspondingly provided with equipment such as a clamping cylinder, a clamping cylinder and a booster pump. The above equipment needs to be lubricated by adding lubricating oil regularly to ensure the normal operation of the full-automatic busbar lifting frame.

[0034] In the prior art, an air source triple unit is installed to achieve the lubrication function. Specifically, the air source triple unit sequentially includes a water separator, a pressure reducing valve and an oil mist lubricator. Generally, in summer, a multi-functional overhead crane air compressor is used to provide compressed air for the air source triple unit. The compressed air contains a large amount of moisture, and through the existing air source triple unit, the filtration is not thorough, and it is easy for moisture and impurities to enter equipment such as the clamping cylinder, the clamping cylinder, the booster pump and the reversing solenoid valve, affecting the normal operation of the above equipment, and also affecting the service life and safety of the above equipment during use.

[0035] Please refer to Figures 1 to 8 To solve the above technical problems, the present application provides a compressed air filtration assembly 1000, which includes an air inlet pipe 11, an air outlet pipe 12, a main body 1, a flow blocking structure 2, a filtration structure 3 and a condensation structure 4. The main body 1 is connected to the air inlet pipe 11 and the air outlet pipe 12. An accommodation cavity 13 is formed inside the main body 1, and the accommodation cavity 13 communicates with the air inlet pipe 11 and the air outlet pipe 12. The air inlet pipe 11 has a cooling pipe section 111 extending into the accommodation cavity 13. The flow blocking structure 2 is detachably installed inside the cooling pipe section 111, and the flow blocking structure 2 is used to obstruct the flow of compressed air. The filtration structure 3 is movably installed inside the accommodation cavity 13, and the filtration structure 3 is arranged between the air inlet pipe 11 and the air outlet pipe 12 along the air flow transmission direction. And the condensation structure 4 is located inside the accommodation cavity 13, and the condensation structure 4 is arranged on the periphery of the cooling pipe section 111.

[0036] It can be understood that the accommodation cavity 13 inside the main body 1 communicates with the air inlet pipe 11 and the air outlet pipe 12, providing a path for the flow of compressed air. And the air inlet pipe 11 has a cooling pipe section 111 extending into the accommodation cavity 13. Correspondingly, the flow blocking structure 2 is detachably installed inside the cooling pipe section 111, and the condensation structure 4 is located on the periphery of the cooling pipe section 111. The flow blocking structure 2 is used to obstruct the flow of compressed air. Due to the cooling effect of the condensation structure 4, the compressed air slowly passing through the cooling pipe section 111 can fully exchange heat with the condensation structure 4, so that the moisture inside the high-temperature compressed air condenses into liquid, thereby reducing the moisture content in the compressed air. The compressed air after separating the moisture flows out from the cooling pipe section 111. Since the filtration structure 3 is movably installed inside the accommodation cavity 13 and the filtration structure 3 is arranged between the air inlet pipe 11 and the air outlet pipe 12 along the air flow transmission direction, the compressed air flowing out from the cooling pipe section 111 is filtered by the filtration structure 3 to remove solid impurities and then input into the air outlet pipe 12 and output. Therefore, the compressed air filtration assembly 1000 and the compressed air source pipeline in the embodiments of the present application can reduce the moisture content of the compressed air and improve the cleanliness of the compressed air. While ensuring the filtration effect, it is also convenient to cooperate with subsequent equipment to realize the maintenance of the equipment on the fully automatic bus lifting frame.

[0037] Furthermore, in the embodiments of the present application, the compressed air flows through the air inlet pipe 11, the condensation pipe section of the air inlet pipe 11, the flow blocking structure 2, the filtration structure 3 in sequence and reaches the air outlet pipe 12. During this process, the condensation structure 4 cools and condenses the condensation pipe section to separate the moisture inside the compressed air.

[0038] In some other embodiments, please refer to Figures 1 to 3, the main body 1 has a top and a bottom that are oppositely arranged. The air outlet pipe 12 is close to the top of the main body 1, and the air inlet pipe 11 is close to the bottom of the main body 1. Arranging the air outlet pipe 12 at the top helps to reduce the problem of incomplete moisture removal caused by liquid accumulation, because the liquid generated during the condensation process will flow to the bottom under the action of gravity, thereby reducing the possibility of liquid entering the air outlet pipe 12 and being discharged with the compressed air. Moreover, this vertical layout helps the compressed air to flow smoothly inside the main body 1, reducing the resistance and eddy current of the air flow, thereby improving the efficiency of the system.

[0039] Furthermore, please refer to Figure 4 , the flow blocking structure 2 includes a base 21 and a spoiler 22. The base 21 is installed at the end of the cooling pipe section 111. The base 21 is provided with air outlet holes 211. The spoiler 22 is connected to the base 21. The spoiler 22 extends along the length direction of the cooling pipe section 111 and is used to extend into the cooling pipe section 111. The spoiler 22 is bent in its extending direction to block the flow of the compressed air. It can be understood that the base 21 is provided with air outlet holes 211, and the air outlet holes 211 can allow the compressed air to pass through the base 21 after being blocked by the spoiler 22 and continue to flow to the filtering structure 3 and the air outlet pipe 12 to realize the subsequent filtering steps and form a complete gas flow path.

[0040] For the spoiler 22, the spoiler 22 is bent in its extending direction. With this setting, the compressed air is blocked when flowing through the spoiler 22, and the flow direction and flow rate are changed. This not only helps to reduce the flow rate of the compressed air, but also helps the compressed air to form eddies or backflows in the cooling pipe section 111, thereby increasing the contact time between the air and the inner wall of the cooling pipe section 111, and then improving the condensation effect.

[0041] Further, the spoiler 22 has a plurality of peak portions 221 that protrude toward the bottom of the main body 1, and liquid leakage holes 222 are respectively provided at each peak portion 221. On the one hand, the setting of the peak portions 221 on the spoiler 22 can increase the contact area between the spoiler 22 and the compressed air, thereby more effectively blocking and changing the flow direction of the air flow. Moreover, the protruding shape of the peak portions 221 can also introduce more turbulence and eddies during the flow blocking process, which helps to enhance the contact between the compressed air and the inner wall of the condensation pipe section, thereby improving the condensation effect. On the other hand, for the liquid leakage holes 222, the liquid leakage holes 222 provided at the peak portions 221 are mainly used to allow the condensed water generated during the condensation process to pass through. These liquid leakage holes 222 ensure that the condensed water can be discharged in time, preventing it from accumulating on the spoiler 22, thereby keeping the spoiler 22 clean and efficient.

[0042] Please refer to Figure 5, in some embodiments, the spoiler 22 includes a plurality of spoiler vanes 223, and the plurality of spoiler vanes 223 are connected by a rotating shaft 224. The spoiler structure 2 further includes a telescopic rod 23, and the telescopic rod 23 has a telescopic stroke along the length direction of the cooling pipe section 111. One end of the telescopic rod 23 is connected to the base 21, and the other end is connected to the spoiler vane 223 far from the base 21. The telescopic rod 23 moves to drive the angle change between the spoiler vanes 223. It can be understood that a cross-section is formed in the cooling pipe section 111 along the air flow direction, and the spoiler vane 223 has a projected area at the above cross-section. By driving the angle change between the spoiler vanes 223 through the telescopic movement of the telescopic rod 23, the change in the projected area of the spoiler vane 223 at the above cross-section can be realized. Specifically, when the telescopic rod 23 extends, the angle between the spoiler vanes 223 becomes larger, and the edge of the spoiler vane 223 is farther away from the inner wall of the cooling pipe section 111, and the projected area of the spoiler vane 223 on the cross-section decreases, so that the resistance received by the compressed air flowing through the spoiler vane 223 becomes smaller; on the contrary, when the telescopic rod 23 shortens, the angle between the spoiler vanes 223 becomes smaller, and the edge of the spoiler vane 223 is closer to the inner wall of the cooling pipe section 111, and the projected area of the spoiler vane 223 on the cross-section increases, so that the resistance received by the compressed air flowing through the spoiler vane 223 also becomes larger.

[0043] Therefore, by adjusting the length of the telescopic rod 23, the adjustment of the resistance of the compressed air can be realized. When it is necessary to increase the filtration speed, the telescopic rod 23 can be appropriately lengthened to reduce the resistance received by the compressed air, increase the flow rate of the compressed air, and achieve the effect of efficient filtration. When it is necessary to reduce the water content in the compressed air components, the length of the telescopic rod 23 can be appropriately shortened to increase the resistance received by the compressed air, ensure the sufficient condensation of the compressed air, and achieve a better condensation effect. With such a setting, the flow resistance structure 2 can be applied to different scenarios to meet diverse functional requirements.

[0044] Please refer to Figure 3 or Figure 7, It can be understood that the compressed air filtering assembly 1000 in the present application further includes a liquid drainage structure 5. The liquid drainage structure 5 is located at the bottom of the main body 1 and is communicated with the cooling pipe section 111. The liquid drainage structure 5 includes a connecting pipe 51, a liquid accumulation tank 52 and a valve body 53. An installation hole 1111 is provided on one side of the cooling pipe section 111 close to the bottom of the main body 1. The connecting pipe 51 is inserted into the installation hole 1111. The liquid accumulation tank 52 is communicated with the connecting pipe 51. A liquid outlet pipe is connected to the bottom of the liquid accumulation tank 52. The valve body 53 is installed at the liquid outlet pipe. The valve body 53 has a closed state and an open state. The valve body 53 switches between the closed state and the open state to turn off or conduct the liquid outlet pipe. Among them, the liquid drainage structure 5 is mainly connected to the cooling pipe section 111 through the connecting pipe 51 to conduct the condensed water accumulated in the cooling pipe section 111 to the liquid accumulation tank 52, and discharge the condensed water when the condensed water reaches a certain level. The valve body 53 can ensure that when liquid drainage is not required, the liquid outlet pipe can be effectively turned off to prevent liquid backflow or leakage.

[0045] In some embodiments, the valve body 53 can be controlled by an electric control scheme. For example, when it is detected that the water level in the liquid accumulation tank 52 reaches a certain condition, the valve body 53 is automatically opened to drain the condensed water, and when the water level in the liquid accumulation tank 52 drops to a certain level, the valve body 53 is closed to avoid leakage of compressed air. On the one hand, it can realize the automation of the overall process, and on the other hand, it can ensure that the compressed air flows out from the air outlet pipe 12.

[0046] In some of these embodiments, reference can be made to Figures 6 to 8 , the filtering structure 3 includes a bracket 31 and a filter screen 32. The bracket 31 has a stroke of reciprocating movement from the inside of the main body 1 to the outside of the main body 1. The bracket 31 and the main body 1 are slidably connected. The bracket 31 has a locking portion 311. The locking portion 311 is used to cooperate with the main body 1 to fix the bracket 31. The filter screen 32 is installed at the bracket 31. Among them, the bracket 31 is used to carry the filter screen 32 and has a stroke of reciprocating movement from the inside of the main body 1 to the outside, thereby driving the filter screen 32 to move, facilitating the staff to quickly clean, replace or maintain the filter screen 32. The bracket 31 and the main body 1 are slidably connected, enabling smooth movement between the two. In addition, the bracket 31 is also provided with a locking portion 311. The locking portion 311 can realize the fixation between the main body 1 and the bracket 31. The locking portion 311 also has an unlocked state. By releasing the fixation of the locking portion 311, the relative movement between the main body 1 and the bracket 31 can be realized. In some other embodiments, the locking portion 311 includes a magnetic attraction assembly. The magnetic attraction assembly includes two magnets. The two magnets are respectively located on the bracket 31 and the main body 1. The fixation between the bracket 31 and the main body 1 is realized through magnetic attraction. When the external force on the bracket 31 is greater than the magnetic force, the relative movement between the bracket 31 and the main body 1 can be realized.

[0047] Furthermore, the number of the filtering structures 3 is at least two. Among them, the filter screen 32 close to the bottom of the main body 1 is a screen with a mesh size of more than 200 meshes, and the filter screen far from the bottom of the main body 1 is a screen with a mesh size of more than 400 meshes. The compressed air is preliminarily screened and re-screened through the filter screens 32 with different aperture sizes, so as to more effectively achieve the filtering effect of the compressed air, avoid impurities from entering the subsequent components, and ensure the safety of the system operation.

[0048] Among them, one of the bracket 31 and the main body 1 is provided with a slide rail, and the other is provided with a slider. The slide rail and the slider cooperate to enable the bracket 31 to reciprocate along the inside of the main body 1 to the outside of the main body 1. By realizing the movable connection between the bracket 31 and the main body 1 in a sliding manner, on the one hand, it can prevent impurities from entering the air outlet pipe 12 through the gap without being screened by the filter screen 32 due to the clamping between the slide rail and the slider. On the other hand, the connection mode of the slide rail and the slider makes the movement of the bracket 31 smoother and more reliable, facilitating the installation, disassembly and replacement of the filter screen 32.

[0049] Correspondingly, specifically, reference can be made to Figures 7 to 8 , an installation groove 131 is provided inside the main body 1. The installation groove 131 and the locking portion 311 are assembled in cooperation. The locking portion 311 includes a plurality of bumps 3111. Each bump 3111 has a limit protrusion 3111a and an avoidance groove 3111b. The limit protrusion 3111a can be pressed into the avoidance groove 3111b under the action of an external force. In order to install the bracket 31 inside the main body 1, first push the bracket 31 along the slide rail until the bump 3111 abuts against the installation groove 131, and then apply an external force (such as pressing or pushing with the hand) to the bracket 31, so that the limit protrusion 3111a on the bump 3111 enters the avoidance groove 3111b, so that the bump 3111 enters the installation groove 131. When the bump 3111 moves to the bottom of the installation groove 131, the limit protrusion 3111a will automatically reset, locking the component in a fixed position. When it is necessary to release the locking, also apply an external force (such as pressing or pushing with the hand) to the bracket 31, so that the limit protrusion 3111a on the bump 3111 enters the avoidance groove 3111b, so that the bump 3111 moves outside the installation groove 131, releasing the locking between the two.

[0050] Through the limit protrusion 3111a and the avoidance groove 3111b on the bump 3111, the flexibility and convenience of the installation of the filtering structure 3 are improved. On the one hand, the limit protrusion 3111a cooperates with the corresponding part of the installation groove 131, which can ensure that the bracket 31 can remain stable without being affected by external forces, prevent it from moving or falling off accidentally, and ensure the filtering effect. In addition, the fixing and disassembly of the bracket 31 can be realized through simple pressing and pulling operations, without the need to use additional tools or adopt complex operation steps, making the overall operation simple and easy.

[0051] In addition, it can be understood that in order to enable the bracket 31 to extend outside the main body 1, the main body 1 is provided with an opening corresponding to the bracket 31. To ensure the sealing performance of the main body 1, a mating seal is provided at the opening. When the bracket 31 and the main body 1 are fixedly engaged, the mating seal and the bracket 31 and the main body 1 are in interference fit to achieve the sealing performance.

[0052] In another embodiment, an installation seal is also provided at the notch of the installation groove 131. Since both the bracket 31 and the main body 1 are made of hard materials, the flexible installation seal can protect the limiting protrusion 3111a, preventing the limiting protrusion 3111a from losing elasticity or being damaged during repeated movements, and can extend the service life of the protrusion 3111. In addition, the installation seal can also be in interference fit with the installation groove 131 and the protrusion 3111, so as to ensure that the compressed air can reach the subsequent components through the filter screen 32, preventing the problem of poor compressed air quality caused by gas leakage and further optimizing the filtering effect of the compressed air.

[0053] Please refer to Figure 3 , the condensation structure 4 includes a water inlet pipe 41, a water outlet pipe 42 and a plurality of condensation pipes 43 communicating therewith. In the embodiment of the present application, the condensation structure 4 is located inside the main body 1 and is arranged close to the cooling pipe section 111, which can better dissipate heat for the cooling pipe, and the main body 1 can play a certain heat preservation and heat insulation effect, making the condensation effect of the condensation structure 4 better. In addition, the number of the condensation pipes 43 is set to be multiple, which can maximize the contact area between the condensation structure 4 and the inside of the main body 1, achieve a better condensation and cooling effect, and thus accelerate the condensation effect of the moisture in the compressed air. In the embodiment of the present application, the cooling medium in the condensation structure 4 flows through a plurality of condensation pipes 43 from the water inlet pipe 41 and converges to the water outlet pipe 42. Generally, the water inlet pipe 41 and the water outlet pipe 42 are also connected to an external cooling source, which is not limited in this application, and the cooling source can be a cooling tower, a refrigerant supply device or a water tank, etc.

[0054] The present invention also provides a compressed air source pipeline, including: a main pipeline, a compressed air filtering assembly 1000 and an oil mist separator. The specific structure of the above-mentioned compressed air filtering assembly 1000 refers to the above-mentioned embodiments. Since the compressed air source pipeline adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated herein one by one.

[0055] Further, in the embodiments of the present application, the compressed air filtration assembly 1000 is connected to the main pipeline; the oil mist lubricator is connected to the main pipeline and is located downstream of the compressed air filtration assembly 1000 along the flow direction of the compressed air. Therefore, one end of the main pipeline is connected to a multi-functional overhead crane air compressor, which provides the initial compressed air. The compressed air flows through the main pipeline to the compressed air filtration assembly 1000. After filtering the compressed air, the filtered compressed air is input into the oil mist lubricator, and then each device on the fully automatic busbar lifting frame is lubricated. After filtration, the water content in the compressed air is reduced, and solid impurities are filtered out, which can extend the service life of the device and the safety during the use of the device.

[0056] In some other embodiments, in order to further enhance the filtration effect of the compressed air source pipeline, the number of the compressed air filtration assemblies 1000 is set to two, and the two groups of compressed air filtration assemblies 1000 are connected in sequence, so as to perform secondary filtration on the compressed air and can more effectively improve the quality of the compressed air.
