Description

Technical Field

[0001] The invention relates to the technical field of hydrogen centrifugal separation, in particular to a gas-liquid separator for hydrogen preparation. Background Art

[0002] The hydrogen gas-liquid separator is an important component in the water electrolysis hydrogen production equipment. Its main function is to separate hydrogen from liquid water. During the water electrolysis process, water is decomposed into hydrogen and oxygen, and enters the hydrogen gas-liquid separator together with the circulating electrolyte. Inside the separator, the gas and liquid are separated through specific physical or mechanical effects, and the separated hydrogen is further processed for use by users.

[0003] However, the existing hydrogen centrifugal separation equipment cannot adjust the air inlet angle according to different operating conditions and gas-liquid mixture characteristics during use, and cannot adjust the mixed liquid water inlet angle. It is also impossible to change the flow trajectory of the hydrogen mixed liquid entering the centrifuge, resulting in the liquid flowing too fast or too slow in the separation chamber. When the mixed liquid flows too fast, the residence time of the gas and liquid in the centrifuge may be insufficient, resulting in reduced separation effect. This is because the gas and liquid require sufficient time to be stratified and separated under the action of centrifugal force, and a speed that is too slow may cause the separation process to be too slow, thereby reducing the overall separation efficiency, and thus being unable to control the eddy currents and turbulence of the gas in the centrifuge, making it impossible to achieve more efficient separation of the gas and liquid.

[0004] In addition, during the hydrogen separation process, there are atomized water droplets in the separation chamber system. These tiny water droplets may move with the airflow and gather at the upper exhaust filter holes of the separation equipment. In the chemical production process, it is often necessary to separate the mixed gas to obtain the required gas components. When the mixed gas contains water vapor or other condensable liquids, these liquids may condense into water droplets during the separation process and adhere to the filter holes to form a water droplet film that affects the separation effect. In order to prevent the filter holes from being blocked and ensure the separation efficiency, these water droplet films need to be removed. The filter holes are usually designed to block larger particles of impurities or liquids, and the atomized water droplets are very small in size. It is easy to form a layer of water film on the surface of the filter holes or block the filter holes, resulting in an increase in the resistance of the gas passing through the filter holes. The blockage of the filter holes not only affects the collection of the gas, but may also increase the operating load of the equipment, such as requiring higher pressure or more energy to maintain the flow of the gas, thereby reducing the overall performance of the equipment.

[0005] Therefore, a gas-liquid separator for hydrogen preparation is proposed to solve the above problems. Summary of the invention

[0016] Compared with the prior art, the gas-liquid separator for hydrogen preparation provided by the present invention has the following beneficial effects: 1. By setting the adjustable angle tilt mechanism and adjusting the liquid outlet angle of the liquid outlet pipe, not only can the flow state of the liquid entering the centrifugal separator be optimized and the impact and disturbance of the liquid on the gas be reduced, but also the composition and flow rate of the mixture are different under different working conditions, and the adjustable liquid inlet angle and reasonable liquid inlet angle are conducive to the uniform distribution of the liquid in the centrifuge, reducing eddy and turbulent phenomena, thereby improving the separation efficiency of hydrogen, allowing users to make adjustments according to actual needs to adapt to different working conditions and ensure the separation effect. Compared with the existing technology, this design enhances the flexibility of the centrifugal separator, enables it to play a role in a wider range of applications, improves the versatility and adaptability of the equipment, and reduces the use phenomenon of poor separation efficiency of the equipment.

[0017] 2. Through the setting of the guide plate, the guide plate can guide the gas-liquid mixture to flow in the guide plate and form a high-speed rotating flow, and use the centrifugal force to effectively separate the liquid from the gas. This design can significantly improve the separation efficiency and reduce the amount of liquid entrained in the gas. Compared with the traditional separator, the spiral guide plate not only changes the flow direction of the fluid, but also optimizes the flow field structure through its special geometric shape. Moreover, this optimization makes the fluid more evenly distributed in the centrifugal separator, reduces the velocity gradient and pressure gradient between the fluids, thereby reducing the resistance loss caused by the interaction between the mixed liquids. Therefore, the centrifugal separator designed with the guide plate has smaller resistance loss during the separation process, which is not only conducive to reducing the energy consumption and operating cost of the equipment, but also the design of the guide plate is conducive to maintaining the stability of the swirl, so that the gas-liquid mixture maintains a laminar state during the separation process, reducing energy loss and the occurrence of back-mixing and entrainment.

[0018] 3. The demisting and anti-clogging mechanism can not only effectively prevent the separation filter from being blocked by solid particles or impurities in the liquid, maintain the permeability of the separation filter, and ensure the continuity and efficiency of the separation process, but also scrape the surface of the separation filter through the scraper, which can not only keep the separation filter clean and unobstructed, but also enable more liquid to be separated through the separation filter, thereby improving the overall separation efficiency. The reciprocating sliding of the separation filter may also promote the redistribution of the liquid in the centrifugal field, further improving the separation effect. Compared with the prior art, this design can adapt to different types of liquid mixtures and different separation requirements. By adjusting the frequency and amplitude of knocking and sliding, the separation effect can be optimized to meet different production needs. Moreover, this design realizes automatic cleaning and maintenance of the filter, reducing the need for manual intervention. Since the need for manual cleaning of the filter is reduced, maintenance costs and time can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below based on the accompanying drawings and embodiments. Example 1

[0023] Please refer to Figures 1 to 9 As shown: In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a gas-liquid separator for hydrogen preparation, including a separation platform 1, a separation chamber 11 is fixedly connected to the separation platform 1, a demisting chamber 12 is fixedly connected to the outer surface of the upper end of the separation chamber 11, a separation filter 13 is slidably connected to the inner wall of the upper end of the separation chamber 11, a guide plate 14 is fixedly connected to the inner wall of the separation chamber 11 near the lower part of the separation filter 13, and also includes an adjustable angle tilting mechanism 2 and a demisting anti-blocking mechanism 3, the adjustable angle tilting mechanism 2 is arranged on the guide plate 14, and the demisting anti-blocking mechanism 3 is arranged on the separation filter 13; The adjustable angle tilting mechanism 2 is used to adjust the tilting angle of the outflowing water flow; The demisting and anti-clogging mechanism 3 is used to prevent the separated atomized water droplets from clogging the filter holes of the separation filter screen 13; The adjustable angle tilt mechanism 2 includes a threaded adjustment rod 21, the outer surface of one end of the threaded adjustment rod 21 is rotatably connected to the inner wall of the separation bin 11, and the other end of the threaded adjustment rod 21 is rotatably connected to a guide fixing plate 22, and the guide fixing plate 22 is fixedly connected to the upper end of the guide plate 14 at one end away from the threaded adjustment rod 21, and sliding grooves are provided on both sides of the guide fixing plate 22, and a multifunctional slider 23 is slidably connected to the bottom of the guide fixing plate 22, and the middle part of the multifunctional slider 23 is threadedly connected to the threaded adjustment rod 21, and both sides of the multifunctional slider 23 are slidably connected to the sliding grooves provided in the guide fixing plate 22; The outer surfaces of both sides of the multifunctional slider 23 are rotatably connected with swing arms 24, and one end of the swing arm 24 away from the multifunctional slider 23 is rotatably connected with an auxiliary inclined plate 25, and both sides of the auxiliary inclined plate 25 away from the end of the swing arm 24 are rotatably connected to the guide plate 14, and a liquid outlet pipe 26 is slidably connected to the auxiliary inclined plate 25; One end of the liquid outlet pipe 26 is fixedly connected to a hemispherical water guide plate 27, and the other end of the liquid outlet pipe 26 is fixedly connected to a water guide trough body. The outer surface of the hemispherical water guide plate 27 is slidably connected to a hemispherical cover 28. The side of the hemispherical cover 28 away from the liquid outlet pipe 26 is fixedly connected to a liquid inlet pipe 29, and the outer surface of the liquid inlet pipe 29 is fixedly connected to the separation chamber 11. in: Figure 3 and Figure 4 The dividing line in the middle of the middle liquid outlet pipe 26 indicates that the pipe is not the end point of the pipe here, but it is not fully drawn here due to the scale of the drawing, layout restrictions or other reasons. The guide plate 14 is evenly fixed on the inner wall of the separation chamber 11 in a spiral shape; In the prior art, when the hydrogen centrifugal separation device is in use, it is impossible to adjust the air inlet angle according to different operating conditions and gas-liquid mixture characteristics, and it is impossible to adjust the angle of the mixed liquid inlet, and it is impossible to change the flow trajectory of the hydrogen mixed liquid entering the centrifuge, so that the liquid flows too fast or too slow in the separation chamber. When the mixed liquid flows too fast, the residence time of the gas and liquid in the centrifuge may be insufficient, resulting in reduced separation effect. This is because the gas and liquid need enough time to be stratified and separated under the action of centrifugal force, and too slow a speed may cause the separation process to be too slow, thereby reducing the overall separation efficiency, and thus it is impossible to control the vortex and turbulence of the gas in the centrifuge, so that the gas and liquid cannot be separated more efficiently, which is different from the prior art. Compared with the prior art, through the implementation of this embodiment, by adjusting the liquid outlet angle of the liquid outlet pipe 26, not only can the flow state of the liquid when entering the centrifugal separator be optimized and the impact and disturbance of the liquid on the gas be reduced, but also under different working conditions, the composition and flow rate of the mixture may be different. A reasonable liquid inlet angle is conducive to the uniform distribution of the liquid in the centrifuge, reducing eddy and turbulent phenomena, thereby improving the separation efficiency of hydrogen, and the adjustable liquid inlet angle allows the user to adjust according to actual needs to adapt to different working conditions and ensure the separation effect. Compared with the prior art, this design enhances the flexibility of the centrifugal separator, enables it to play a role in a wider range of applications, improves the versatility and adaptability of the equipment, and reduces the use phenomenon of poor separation efficiency of the equipment.

[0024] For further examples, please refer to Figures 1 to 9 As shown: The demisting and anti-blocking mechanism 3 includes a driving gear 31, which is rotatably connected in the demisting chamber 12, and a multifunctional slide rail gear ring 32 is meshed on the tooth surface of the driving gear 31, and the bottom of the multifunctional slide rail gear ring 32 is slidably connected to the upper end of the separation chamber 11, and a scraper 33 is fixedly connected to the upper surface of the multifunctional slide rail gear ring 32, and the bottom of the end of the scraper 33 away from the multifunctional slide rail gear ring 32 is in contact with the upper surface of the separation filter 13; The demisting and anti-blocking mechanism 3 also includes a gear shaft 34, one end of which is rotatably connected to the inner wall of the separation chamber 11, and the other end of the gear shaft 34 is fixedly connected to a convex extrusion block 35, and a gear ring is fixedly connected to the outer surface of the middle part of the gear shaft 34, and the multifunctional slide rail gear ring 32 is evenly provided with sliding teeth near the lower surface of the gear shaft 34, and the tooth surface of the sliding teeth is meshed with the gear ring; A support plate 39 is fixedly connected to the inner wall of the separation bin 11 near the gear shaft 34, and an extrusion rod 36 is slidably connected in the support plate 39. A compression spring 37 is sleeved on the outer surface of the extrusion rod 36. One end of the compression spring 37 is fixedly connected to the support plate 39, and the other end of the compression spring 37 is fixedly connected to the extrusion rod 36. A collision rod is fixedly connected to the outer surface of the extrusion rod 36, and a vibration transmission block 38 is fixedly connected to the upper surface of the separation filter 13 near the collision rod side of the extrusion rod 36.

[0025] A vibration spring 301 is fixedly connected to the circumference of the lower surface of the separation filter 13, and one end of the vibration spring 301 away from the separation filter 13 is fixedly connected to the separation bin 11. A water filter plate 302 is provided at the bottom of the separation bin 11, and the bottom of the water filter plate 302 is fixedly connected to the inner wall of the separation bin 11; Among them: the driving gear 31 is fixedly connected to the motor driving shaft, the vibration spring 301 is circumferentially fixedly connected to the bottom of the separation filter screen 13, and the gear shaft 34 to the support plate 39 are circumferentially arranged on the upper surface of the separation filter screen 13.

[0026] In the prior art, during the hydrogen separation process, atomized water droplets exist in the separation chamber 11 system. These tiny water droplets may move with the air flow and gather at the upper exhaust filter holes of the separation device. Since the filter holes are usually designed to block larger particles of impurities or liquids, and the atomized water droplets are very small in size, they are easy to form a layer of water film on the surface of the filter holes or block the filter holes, resulting in increased resistance to gas passing through the filter holes. The blockage of the filter holes not only affects the collection of gas, but also may increase the operating load of the equipment, such as requiring higher pressure or more energy to maintain the flow of gas, thereby reducing the overall performance of the equipment. Compared with the prior art, through the implementation of this embodiment, not only can the separation filter 13 be effectively prevented from being blocked by solid particles or impurities in the liquid, the permeability of the separation filter 13 is maintained, and the continuity and efficiency of the separation process are ensured, but also the scraper 33 is used to scrape the upper surface of the separation filter 13, so that the separation filter 13 can be kept clean and unobstructed, and more liquid is separated through the separation filter 13, thereby improving the overall separation efficiency. The reciprocating sliding of the separation filter 13 may also promote the redistribution of the liquid in the centrifugal field, further improving the separation effect.

[0027] Everything in the above example works like this: In the initial state: the motor is not started, the vibration spring 301 is not compressed, and the compression spring 37 is not stretched.

[0028] The following is the working process of the adjustable angle tilting mechanism 2 for adjusting the tilting angle of the outflow water flow: When in use, because the end of the liquid inlet pipe 29 close to the outer side of the separation chamber 11 is connected to the liquid inlet of the hydrogen mixed liquid, the hydrogen mixed liquid is then transported through the liquid inlet pipe 29 and flows from the liquid outlet pipe 26 to the guide plate 14 through the connection between the hemispherical water guide plate 27 and the hemispherical cover 28. At the same time, because the guide plate 14 is spirally fixed evenly on the inner wall of the separation chamber 11, when the water flows under the guidance of the guide plate 14 and the spiral guidance of the guide plate 14, the liquid rotates along the separation chamber 11. During the rotation, due to the action of centrifugal force, different components in the mixture begin to separate. Due to the density difference between the lighter molecular weight of gas, especially hydrogen, and the liquid or heavier gas component, they will be subjected to different degrees of centrifugal force. The liquid or heavier gas component is subjected to a larger centrifugal force. As a result, they will be thrown to the wall of the drum and flow downward along the guide plate 14, while lighter gas components such as hydrogen are subject to a smaller centrifugal force and tend to remain in the central area of ​​the middle of the separation chamber 11 or a position closer to the rotation axis. As the liquid mixture flows downward along the guide plate 14, due to the effect of gravity, the liquid tends to gather downward along the wall of the guide plate 14. This gravity effect is conducive to the separation of gas (such as dissolved gas or bubbles) in the liquid from the liquid. As the liquid continues to flow downward, the gravity separation effect on the gas is gradually enhanced, which makes the separation effect between gas and liquid more obvious. Finally, the liquid will further flow downward to the water filter plate 302 under the action of gravity, and flow into the discharge port at the bottom of the separation chamber 11 through the water filter plate 302 to be discharged and collected; At the same time, lighter gases such as hydrogen float upward through the outlet in the center area of ​​the separation chamber 11 or near the rotation axis to the separation filter 13 for filtration and then discharged and collected through the exhaust port above the demisting chamber 12. Due to the centrifugal force, most of the impurities in these gases are separated. In order to prevent the liquid from flowing too fast or too slow in the guide plate 14 and causing low separation efficiency during the purification process, the operator starts to rotate the threaded adjustment rod 21. When the water flow rate needs to be increased accordingly, Figure 4As shown, the operator manually rotates the threaded adjustment rod 21 clockwise. Because the threaded adjustment rod 21 is rotatably connected to the guide fixing plate 22, and the threaded adjustment rod 21 is threadedly connected to the multi-functional slider 23, and the multi-functional slider 23 slides on the guide fixing plate 22, the clockwise rotation of the threaded adjustment rod 21 will drive the multi-functional slider 23 to start sliding to the right along the guide fixing plate 22. At the same time, because the multi-functional slider 23 is rotatably connected to the swing arm 24 on both sides, and the swing arm 24 is rotatably connected to the auxiliary inclined plate 25, and the auxiliary inclined plate 25 is rotatably connected to the guide plate 14 on both sides away from the swing arm 24, the swing arm 24 is pushed to the right by the multi-functional slider 23 sliding to the right. The auxiliary inclined plate 25 starts to rotate clockwise on the guide plate 14 when pushed by the swing arm 24. At this time, the auxiliary inclined plate 25 starts to tilt upward. At the same time, because the liquid outlet pipe 26 is arranged on the auxiliary inclined plate 25, the auxiliary inclined plate 25 tilts and drives the auxiliary inclined plate 25 to start moving upward. Because the hemispherical water guide plate 27 is provided with a semi-arc spherical shape and is slidably connected to the inner wall of the hemispherical cover 28, the liquid outlet pipe 26 drives the hemispherical water guide plate 27 to rotate counterclockwise on the inner wall of the hemispherical cover 28 when pushed upward by the auxiliary inclined plate 25. At this time, the mixed liquid in the liquid inlet pipe 29 is guided by the liquid outlet pipe 26 to make the water flow in the liquid outlet pipe 26 flow more slowly. On the contrary, when the operator rotates the threaded adjustment rod 21 counterclockwise, as shown in FIG. Figure 3 and Figure 4 As shown, the dividing line in the middle of the liquid outlet pipe 26 indicates that the pipe is not the end point of the pipe here, but due to the proportion of the drawing, layout restrictions or other reasons, the following pipe content is not drawn here. At this time, the liquid outlet pipe 26 will start to drive the hemispherical water guide plate 27 to rotate clockwise on the inner wall of the hemispherical cover 28. At this time, because the inclination angle between the liquid outlet pipe 26 and the bottom of the guide plate 14 increases, the flow speed of the mixed liquid begins to accelerate under the guidance of the liquid outlet pipe 26. The change in the inclination angle of the liquid outlet pipe 26 will change the component size of the gravity along the direction of the pipe, thereby affecting the speed at which the liquid is pushed, resulting in a change in the water flow speed. By setting the adjustable angle tilting mechanism 2, by adjusting the outlet of the liquid outlet pipe 26 The liquid inlet angle can not only optimize the flow state of the liquid when it enters the centrifugal separator and reduce the impact and disturbance of the liquid on the gas, but also the composition and flow rate of the mixture may be different under different working conditions. A reasonable liquid inlet angle is conducive to the uniform distribution of the liquid in the centrifuge, reducing eddy currents and turbulence, thereby improving the separation efficiency of hydrogen. The adjustable liquid inlet angle allows the user to adjust it according to actual needs to adapt to different working conditions and ensure the separation effect. Compared with the existing technology, this design enhances the flexibility of the centrifugal separator, enables it to play a role in a wider range of applications, improves the versatility and adaptability of the equipment, and reduces the use of the equipment with poor separation efficiency. Through the setting of the guide plate 14, the guide plate 14 can guide the gas-liquid mixture to form a high-speed rotating flow, and use the centrifugal force to effectively separate the liquid and the gas. This design can significantly improve the separation efficiency and reduce the amount of liquid entrained in the gas. Compared with the traditional separator, the spiral guide plate 14 not only changes the flow direction of the fluid, but also optimizes the flow field structure through its special geometric shape. Moreover, this optimization makes the fluid more evenly distributed in the centrifugal separator, reduces the velocity gradient and pressure gradient between the fluids, thereby reducing the resistance loss caused by the interaction between the mixed liquids. Therefore, the centrifugal separator designed with the guide plate 14 has smaller resistance loss during the separation process. The centrifugal separator designed with the spiral guide plate 14 can have smaller resistance loss during the separation process, which is conducive to reducing the energy consumption and operating cost of the equipment. At the same time, the design of the guide plate 14 is conducive to maintaining the stability of the swirl, so that the gas-liquid mixture maintains a laminar state during the separation process, reducing energy loss and the occurrence of back-mixing and entrainment.

[0029] Please refer to the above working process Figures 1 to 9 .

[0030] The following is the working process of the demisting anti-clogging mechanism 3 for preventing the separated atomized water droplets from clogging the filter holes of the separation filter screen 13: As described above, when hydrogen is separated by the spiral of the guide plate 14, lighter gases such as hydrogen float upward to the separation filter 13 through the outlet in the center area of ​​the separation chamber 11 or near the rotation axis for filtration. During the hydrogen separation process, there are atomized water droplets in the separation chamber 11 system. These tiny water droplets will move with the air flow and gather at the upper exhaust filter holes of the separation device. Since the filter holes are usually designed to block larger particles of impurities, the atomized water droplets are easy to form a layer of water film on the surface of the filter holes or block the filter holes due to their extremely small size, resulting in an increase in the resistance of the gas to pass through the filter holes. At this time, the motor connected to the driving gear 31 is started, as shown in FIG. Figure 6The bottom of the multifunctional slide rail gear ring 32 is slidably connected to the upper end of the separation chamber 11, and the driving gear 31 is driven by the counterclockwise rotation of the motor drive shaft to drive the multifunctional slide rail gear ring 32 to start sliding clockwise on the upper surface of the separation chamber 11. At this time, because the guide fixing plate 22 is fixedly connected to the upper surface of the multifunctional slide rail gear ring 32, and because the scraper plate 33 is away from the bottom of one end of the multifunctional slide rail gear ring 32 and fits the upper surface of the separation filter screen 13, the scraper plate 33 is driven to clean the upper surface of the separation filter screen 13 by the multifunctional slide rail gear ring 32 sliding clockwise on the separation chamber 11. At this time, the water drop film on the upper surface of the separation filter screen 13 begins to be cleaned, and the scraper plate 33 is used to clean the upper surface of the separation filter screen 13, which can not only keep the separation filter screen 13 clean and unobstructed, but also allow more liquid to be separated through the separation filter screen 13, thereby improving the overall separation efficiency. At the same time Figure 8 As shown, because the multifunctional slide rail toothed ring 32 is provided with a sliding tooth near the bottom of the gear shaft 34, and the sliding tooth is meshed with the sliding toothed ring fixed in the gear shaft 34, and because the gear shaft 34 is rotatably connected to the inner wall of the separation bin 11, the multifunctional slide rail toothed ring 32 slides clockwise under the upper surface of the separation bin 11, which drives the gear shaft 34 to start rotating clockwise. At this time, because the circumference of the gear shaft 34 to the support plate 39 is arranged on the separation filter screen 13, because the working principle is the same, only one group is described. Furthermore, because the gear shaft 34 is away from the driving gear 31, The end is fixedly connected to the convex extrusion block 35, and the clockwise rotation of the gear shaft 34 will drive the convex extrusion block 35 to start rotating in the clockwise direction. At this time, when the convex block 35 is pressed onto the upper surface of the separation filter 13, because the separation filter 13 slides on the inner wall of the separation bin 11, the convex extrusion block 35 will cause the separation filter 13 to slide downward on the inner wall of the separation bin 11, and the vibration spring 301 will begin to be compressed. At the same time, the extrusion rod 36 slides on the support plate 39 because of the extrusion, and the support plate 39 is fixedly connected to the inner wall of the separation bin 11; Because the compression spring 37 is sleeved on the extrusion ram 36, and one end of the compression spring 37 is fixedly connected to the support plate 39, and the other end is fixedly connected to the extrusion ram 36, at this time, the convex extrusion block 35 convex block extrudes the extrusion ram 36 synchronously, causing the extrusion ram 36 to start sliding to the right. Fig. 9As shown, the compression spring 37 begins to be stretched, and because a collision rod is provided on the side of the extrusion striker 36 close to the vibration transmission block 38, when the convex extrusion block 35 rotates clockwise to the non-convex block, the convex block no longer squeezes the extrusion striker 36, and the extrusion striker 36 begins to move rapidly to the left under the elastic action of the compression spring 37. At this time, the collision rod on the extrusion striker 36 will quickly hit the vibration transmission block 38. At this time, the vibration of the vibration transmission block 38 will cause the small water droplets in the separation filter 13 to fall off, thereby preventing the water drop film from clogging the filter holes of the separation filter 13. In the chemical production process, it is often necessary to separate the mixed gas to obtain the required gas components. When the mixed gas contains water vapor or other condensable liquids, these liquids may condense into water droplets and form a water drop film during the separation process to affect the separation effect. In order to prevent the filter holes of the separation filter 13 from being blocked and to ensure the separation efficiency, it is necessary to remove these water drop films, and the demisting and anti-clogging mechanism 3 is used. The setting can not only effectively prevent the separation filter 13 from being blocked by solid particles or impurities in the liquid, maintain the permeability of the separation filter 13, and ensure the continuity and efficiency of the separation process, but also scrape the upper surface of the separation filter 13 through the scraper 33, which can not only keep the separation filter 13 clean and unobstructed, but also allow more liquid to be separated through the separation filter 13, thereby improving the overall separation efficiency. The reciprocating sliding of the separation filter 13 may also promote the redistribution of the liquid in the centrifugal field, further improving the separation effect. Compared with the prior art, this design can adapt to different types of liquid mixtures and different separation requirements. By adjusting the frequency and amplitude of knocking and sliding, the separation effect can be optimized to meet different production needs. Moreover, this design realizes automatic cleaning and maintenance of the filter, reduces the need for manual intervention, and reduces maintenance costs and time due to the reduced need for manual cleaning of the filter.
