Description

Technical Field

[0001] The present invention relates to the technical field of spray-washing separation equipment, and particularly relates to a malodorous waste gas treatment equipment with an ultrasonic atomization gas-liquid mixing structure. Background Art

[0002] In the treatment of malodorous waste gas, generally, a deodorizing liquid is used as the atomized liquid to disperse it into a large number of tiny droplets, creating good conditions for the full mixing and reaction with the malodorous waste gas. The ultrasonic atomizer uses high-frequency oscillation to cause the liquid to generate high-frequency vibration under the action of ultrasonic waves, breaking the surface tension of the liquid and crushing the liquid into tiny droplets. By utilizing the solubility difference of some components in the malodorous gas in the liquid absorbent, the easily soluble malodorous gas components are dissolved in the liquid, thereby realizing the transfer from the gas phase to the liquid phase and achieving the purpose of separation and removal. The active components in the liquid absorbent chemically react with the malodorous gas to convert the malodorous gas into harmless or easily treatable substances. The reaction is usually irreversible and can remove the malodorous gas more thoroughly.

[0003] During the waste gas treatment process, the packing is in a relatively static state, the waste gas flows from bottom to top, and the spraying liquid is sprayed from top to bottom. When the waste gas passes through the packing layer, the pollutants in it come into full contact with the liquid film and are removed through physical absorption, chemical reaction and other processes. However, the malodorous waste gas may carry some solid particles, such as dust, particulate matter and other impurities. As the treatment process continues, these impurities will continuously accumulate on the surface and in the voids of the packing, resulting in blockage. The resistance of the packing in this area increases due to the blockage. The gas will bypass these areas in search of a channel with less resistance, forming a gas short circuit. This makes the waste gas unable to come into full contact and react with the liquid on the surface of the packing, and it is difficult to effectively remove the malodorous substances. At the same time, when treating malodorous waste gas containing organic matter, microorganisms will grow using the organic matter in the waste gas and form a thick biofilm on the surface of the packing. The microorganisms, their metabolites, dead bacteria, etc. will interact with the impurities in the waste gas and the components in the spraying liquid to form biofouling. The biofouling will not only block the pores of the packing, but may also change the surface properties of the packing, affecting gas-liquid mass transfer. At the same time, the biofouling may produce odors, having a negative impact on the treatment effect. Summary of the Invention

[0007] The present invention provides a malodorous waste gas treatment device with an ultrasonic atomization gas-liquid mixing structure, comprising: a spray tower, a driving part is arranged in the middle of the top end of the spray tower, and a limiting ring is arranged on the side of the spray tower;

[0008] A packing part, the packing part is located on the inner wall of the spray tower, and the outer wall of the packing part is embedded inside the limiting ring.

A positioning part is arranged on the upper surface of the packing part, and an atomization part is arranged on the upper surface of the positioning part;

[0009] The interior of the spray tower is divided into a strengthened spray area and an initial spray area from top to bottom. The driving part in the strengthened spray area includes a first main shaft connected to the upper surface of the atomization part and a second main shaft connected to the upper surface of the packing part. When the first main shaft and the second main shaft rotate synchronously and in opposite directions, the packing part carrying the packing rotates synchronously with the second main shaft, so that the packing moves inside the packing part. The first main shaft drives the atomization part to rotate, and the rotating atomization part sprays the moving packing evenly. In the primary spray area, the atomization part is fixed on the inner wall of the limiting ring, and the middle part of the packing part is connected to the second main shaft. The fixed atomization part sprays the moving packing;

[0010] Wherein, a rotating block for vertically adjusting the rotation of the packing part is arranged on the inner wall of the limiting ring;

[0011] A limiting groove is opened at the bottom end of the inner wall of the limiting ring, a fixing block is fixedly connected to the inner wall of the limiting groove, and the outer surface of the fixing block is rotationally connected to the middle part of the rotating block in a damping manner;

[0012] Wherein, the atomization part includes a fixing plate fixedly connected to the bottom end of the first main shaft. Spray rods are evenly arranged on the side of the fixing plate. The other end of the spray rod is hermetically slid with an irrigation water pipe. A water storage device for filling liquid is arranged on the inner wall of the irrigation water pipe, and a sliding groove is opened at the bottom end of the irrigation water pipe;

[0013] Wherein, the packing part includes a blocking block embedded in and slidably connected to the inner wall of the limiting ring. The other end of the blocking block is fixedly connected with a leakage net. The central position of the leakage net is ball-joint connected to the second main shaft. Wave plates are symmetrically fixed on the upper surface of the leakage net, and a leakage ring is fixedly connected to the edge position of the upper surface of the leakage net.

[0014] Further, the driving part includes a protection frame fixed in the middle of the top end of the spray tower. A motor is fixedly connected to the middle of the protection frame. The output end of the motor is fixedly connected with a first gear. The middle part of the first gear is fixedly connected to the top end of the second main shaft. A second gear is meshed and connected to the side of the first gear. A third gear is meshed and connected to the lower surface of the second gear. The bottom end of the third gear is fixedly connected to the middle part of the top end of the first main shaft. The second main shaft is embedded inside the first main shaft.

[0015] Further, the positioning member includes a slider slidably connected to the chute. A connecting rod is fixedly connected to the bottom end of the slider, and a limiting ball is fixedly connected to the bottom end of the connecting rod.

[0016] A fixing groove is formed at the top end of the leakage ring. The size of the fixing groove matches the size of the limiting ball. The limiting ball is embedded in the matching fixing groove, and the limiting ball can rotate in multiple directions within the fixing groove.

[0017] Further, the second main shaft includes a positioning shaft fixedly connected to the bottom end of the first gear at the top end. A spherical shaft is fixedly connected to the side of the bottom end of the positioning shaft. A positioning block ball-jointed to the center position of the strainer is fixedly connected to the bottom end of the spherical shaft. Another positioning shaft is fixedly connected to the bottom end of the positioning block. One end of the other positioning shaft penetrates through the atomizing part of the primary spraying area, and another positioning block ball-jointed to the center of the strainer in the primary spraying area is fixedly connected to the bottom end of the other positioning shaft.

[0018] The technical solution provided by the present invention has the following beneficial effects compared with the prior art:

[0019] The present invention is provided with a packing part capable of rotating. When the packing part rotates, fluctuations will be generated. The rotation of the strainer makes the surface of the packing constantly change. The rotation and fluctuations of the packing make it difficult for impurities attached to its surface to stay and accumulate. During the rotation process, centrifugal force will throw out some impurities; the fluctuations make the surface of the packing constantly change, reducing the chance of impurity attachment.

[0020] The present invention is provided with a driving part, which drives the packing part and the atomizing part to rotate in the opposite direction. The rising gas and the spray are further mixed during the waste gas treatment process. The spraying liquid is ejected during the rotation process, disturbing the surrounding gas. This disturbance makes the gas flow more disordered, increasing the contact opportunity and collision frequency between the gas and the spraying liquid droplets, and strengthening the mass transfer process between the gas and the liquid. During the rotation process, under the combined action of centrifugal force and air flow, the spraying liquid droplets can be more evenly distributed in the treatment space, avoiding the over-concentration or sparseness of the liquid droplets in a local area, making the gas-liquid mixing more uniform, and further improving the waste gas treatment effect.

[0021] In the present invention, the spraying area in the spray tower is divided into a strengthened spraying area and an initial spraying area from top to bottom. The atomizing part in the primary spraying area is fixed on the inner wall of the limiting ring. The middle part of the packing part is connected to the second main shaft. The fixed atomizing part sprays the moving packing to complete the primary waste gas treatment. In the strengthened spraying area, the first main shaft and the second main shaft rotate synchronously in opposite directions. The packing part carrying the packing rotates synchronously with the second main shaft, so that the packing moves within the packing part. The first main shaft drives the atomizing part to rotate. The rotating atomizing part uniformly sprays the moving packing. In a dynamic environment, the gas-liquid two-phase can carry out mass exchange more efficiently, accelerating the transfer speed of pollutants in the waste gas to the liquid phase.

[0022] The present invention is provided with a positioning member. The packing part and the atomizing part are connected through the positioning member. When the packing fluctuates, the positioning member, as a connecting structure, can evenly disperse the impact force generated by the shaking, impact, etc. of the packing, avoiding local deformation during the movement of the packing part and affecting the stability of the overall structure.

[0023] The present invention is provided with an atomizing part. When the spray rod rotates to the position of the water storage device, the water storage device fills a certain amount of liquid into the spray rod. As the fixed plate rotates, liquid can be continuously added to the spray rod. There is no need for the spray rod to carry a large amount of liquid during the rotating spraying process, avoiding interference with the spraying process due to changes in the liquid weight. At the same time, only a certain amount of liquid is stored in the spray rod, avoiding the situation of crystallization and pipeline blockage caused by long-term liquid storage, and improving the service life of the device.

Detailed implementation manners

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Embodiment:

[0037] Please refer to Figures 1-8 , the present invention provides a technical solution for a malodorous waste gas treatment device with an ultrasonic atomization gas-liquid mixing structure: The device includes a spray tower 1. The interior of the spray tower 1 is sequentially provided with a demisting layer, a spraying area, and a circulating water area from top to bottom, as Figure 2As shown in the figure, the spraying area is divided into an enhanced spraying area and a primary spraying area. Both spraying areas are composed of a packing part 3, an atomizing part 4, and a positioning part 5. The atomizing part 4 is used for atomizing the liquid, the packing part 3 is used for carrying the packing, the positioning part 5 is located between the packing part 3 and the atomizing part 4. At the top of the spraying tower 1, a driving part 6 is arranged directly above the demister. At the top of the spraying tower 1, an air outlet for discharging the treated gas is arranged around the driving part 6. The packing part 3 is located on the inner wall of the spraying tower 1, and the outer wall of the packing part 3 is embedded inside the limiting ring 2. The packing part 3 is used for carrying the packing with the mixed gas-liquid. The upper surface of the packing part 3 is provided with the positioning part 5, and the upper surface of the positioning part 5 is provided with the atomizing part 4.

[0038] In the prior art, the packing is in a relatively static state. When the waste gas passes through the packing layer, the pollutants in it are in full contact with the liquid film. The malodorous waste gas may carry some solid particles, such as dust, particulate matter and other impurities. As the treatment process continues, these impurities will continuously accumulate on the surface and in the gaps of the packing, resulting in blockage. The resistance of the packing in this area increases due to the blockage. Therefore, the packing part 3 provided in the present invention is set to be in a movable state.

[0039] Reference Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , the driving part 6 includes a protection frame 67 fixed in the middle of the top of the spraying tower 1. A motor 61 is fixedly connected to the middle of the protection frame 67. The output end of the motor 61 is fixedly connected to a first gear 62. The middle of the first gear 62 is fixedly connected to the top end of the second main shaft 66. A second gear 63 is meshed and connected to the side of the first gear 62. A third gear 64 is meshed and connected to the lower surface of the second gear 63. The bottom end of the third gear 64 is fixedly connected to the middle of the top end of the first main shaft 65. The second main shaft 66 is embedded inside the first main shaft 65. The atomizing part 4 in the primary spraying area is fixed on the inner wall of the limiting ring 2. The middle of the packing part 3 is connected to the second main shaft 66. The fixed atomizing part 4 sprays the movable packing. The packing part 3 includes a blocking block 32 embedded in and slidably connected to the inner wall of the limiting ring 2. The other end of the blocking block 32 is fixedly connected to a leakage net 31. The central position of the leakage net 31 is ball-joint connected to the second main shaft 66. Wave plates 33 are symmetrically fixed on the upper surface of the leakage net 31. A leakage ring 34 is fixedly connected to the edge position of the upper surface of the leakage net 31.

[0040] The motor 61 starts to drive the rotation of gear one 62. The rotation of gear one 62 drives the rotation of main shaft two 66. At the same time, the rotation of gear one 62 is transmitted to gear three 64 through the meshing gear two 63. Gear three 64 rotates in the opposite direction to gear one 62. Gear three 64 drives the rotation of main shaft one 65. The rotation of main shaft one 65 drives the movement of the atomizing part 4 in the intensive spraying area. The rotation of main shaft two 66 drives the rotation of the packing part 3. The overall rotation of the packing part 3 causes the packing carried inside to change its position inside the packing part 3 under the action of centrifugal force and friction. The surface of the corrugated plate 33 is designed with an arc shape that is large at one end and small at the other end. When the corrugated plate 33 rotates with the sieve 31, the corrugated plate 33 will push the packing, causing differences in speed and direction of the packing at different positions. This irregular movement of the packing further avoids the occurrence of blockage.

[0041] The rotation speeds up the renewal of the liquid film on the surface of the packing, shortening the residence time of the liquid on the surface of the packing. This is beneficial to improving the mass transfer rate between gas and liquid. At the same time, the tumbling and collision of the packing make the diffusion path of gas and liquid inside the packing more complex and tortuous, increasing the contact time and contact area between gas and liquid, and further strengthening the gas-liquid mass transfer effect.

[0042] The rotation of the sieve 31 drives the movement of the packing, making the flow of gas and liquid in the packing layer more disordered and sufficient, avoiding local short-circuit or channeling phenomena of gas and liquid in the packing layer, thus promoting the uniform contact of gas and liquid and improving the stability of the mass transfer efficiency.

[0043] During the rotation of the packing, the impurities on its surface are more easily thrown off the surface of the packing due to the action of centrifugal force. At the same time, the tumbling and collision of the packing will also make the impurities already attached to the surface of the packing more likely to fall off, thereby reducing the attachment and accumulation of impurities on the packing and reducing the risk of blockage.

[0044] Due to the movement of the packing, its position in the sieve 31 is constantly changing, making the gaps between the packings not easily blocked by impurities or sediments, able to maintain a good gap structure, ensuring the smooth flow of gas and liquid, and extending the service life of the packing and the stable operation time of the equipment.

[0045] The driving part 6 in the enhanced spraying area includes a first main shaft 65 connected to the upper surface of the atomizing part 4 and a second main shaft 66 connected to the upper surface of the packing part 3. When the first main shaft 65 and the second main shaft 66 rotate synchronously and in opposite directions, the packing part 3 carrying the packing rotates synchronously with the second main shaft 66, causing the packing to move within the packing part 3. The first main shaft 65 drives the atomizing part 4 to rotate, and the rotating atomizing part 4 sprays the moving packing evenly. At the bottom end of the inner wall of the limiting ring 2, a limiting groove 21 is provided. A fixing block 22 is fixedly connected to the inner wall of the limiting groove 21. A knob spring is sleeved on the outer surface of the fixing block 22, and the knob spring is connected to the middle of one end of the rotating block 23. When the rotating block 23 rotates around the fixing block 22, it needs to overcome the elastic force of the knob spring. The inner wall size of the limiting groove 21 is slightly larger than the diameter size of the blocking block 32, and there is a moving space for the blocking block 32 on the inner wall of the limiting groove 21.

[0046] Reference Figure 8 , the second main shaft 66 includes a positioning shaft 661 with its top fixedly connected to the bottom end of the first gear 62. A ball shaft 662 is fixedly connected to the side of the bottom end of the positioning shaft 661. A positioning block 663 is fixedly connected to the bottom end of the ball shaft 662 and is ball-joint connected to the center position of the sieve 31. A positioning block 663 is fixedly connected to the bottom end of the positioning block 663, and the other positioning shaft 661 penetrates through the atomizing part 4 in the primary spraying area at one end. A positioning block 663 is fixedly connected to the bottom end of the other positioning shaft 661 and is ball-joint connected to the center of the sieve 31 in the primary spraying area. A positioning groove is provided at the middle position of the sieve 31. The bottom end of the positioning groove is designed in a spherical shape, and the size of the spherical part at the bottom end is slightly larger than the size of the positioning block 663. An arc-shaped groove for clamping and limiting the ball shaft 662 is provided on the side of the inner wall of the positioning groove.

[0047] The rotation of the positioning shaft 661 drives the rotation of the ball shaft 662. The rotation of the ball shaft 662 drives the rotation of the sieve 31. The rotation of the sieve 31 drives the rotation of the blocking block 32. The rotation of the blocking block 32 contacts the protruding part of the uniformly arranged rotating block 23. The blocking block 32 can pass through the area of the limiting groove 21 only after gradually overcoming the elastic force of the rotating block 23 when contacting the rotating block 23. Due to the interference of this acting force during the rotation process, the sieve 31 will have a certain fluctuation when jointly acted upon by the rotating block 23 and the blocking block 32.

[0048] During the rotation of the packing section 3, there is also a vertical movement. In addition to rotating with the sieve 31, the packing will move irregularly up and down and left and right within the sieve 31 under the action of fluctuations, forming a complex three-dimensional movement trajectory. This complex movement causes the relative positions of the packing to change continuously, increasing the contact opportunities and contact area between the packing and the gas-liquid. The fluctuations will intensify the collision and friction between the packing and between the packing and the sieve 31. Under the combined action of rotation and fluctuations, the collision frequency and intensity between the packing particles both increase. This helps to remove dirt and impurities on the surface of the packing, prevent the packing from being blocked, and at the same time can continuously update the surface of the packing, improving the gas-liquid mass transfer efficiency; during the rotation, the centrifugal force will throw out some impurities, and the fluctuations make the surface of the packing constantly change, reducing the chance of impurity attachment. When treating malodorous waste gas containing dust, dust and other impurities are not easy to accumulate on the packing, reducing the blockage risk and extending the operation cycle of the equipment.

[0049] The synergistic effect of rotation and fluctuations makes the distribution of the packing in the sieve 31 more uniform. The centrifugal force generated by rotation will make the packing tend to move outwards, while the fluctuations will disrupt this single centrifugal distribution trend, making the packing more evenly distributed at different positions and heights in the sieve 31, avoiding excessive accumulation or sparseness of the packing in local areas, thereby improving the overall mass transfer efficiency of the packing layer. During the rotation and fluctuation of the sieve 31, the distribution of the packing is not fixed, but will be dynamically adjusted according to changes in conditions such as gas-liquid flow rate and pressure. When the gas-liquid flow rate is large or the pressure is high, the packing may be arranged more closely under the action of fluctuations to adapt to the larger load; when the gas-liquid flow rate is small or the pressure is low, the packing may be relatively looser to ensure sufficient contact and mass transfer between the gas and liquid. The complex movement and uniform distribution of the packing make the mass transfer process of the gas-liquid in the packing layer more sufficient and efficient. When the gas-liquid passes through the packing layer, it will fully contact the continuously moving and updated surface of the packing, increasing the diffusion and reaction opportunities between the gas and liquid, thereby improving the mass transfer efficiency and treatment effect. The rotation and fluctuation of the sieve 31 will transfer mechanical energy to the packing, enabling the packing to obtain kinetic energy and move. This energy transfer not only promotes the movement and mass transfer process of the packing, but also changes the flow direction and velocity distribution of the gas-liquid, further optimizing the gas-liquid mass transfer effect.

[0050] Reference Figure 2 and Figure 4 As shown in FIGS. 6 and 7, the atomizing section 4 includes a fixing plate 41 fixedly connected to the bottom end of the main shaft 65. Spray rods 42 are uniformly arranged on the side of the fixing plate 41. The other end of the spray rod 42 is hermetically slid with an irrigation pipe 43. A water storage device 44 for filling liquid is arranged on the inner wall of the irrigation pipe 43. A chute 45 is opened at the bottom end of the irrigation pipe 43.

[0051] The rotation of the main shaft 65 drives the rotation of the fixed plate 41, and the rotation of the fixed plate 41 drives the rotation of the spray rod 42. When the spray rod 42 rotates to the position of the water storage device 44, the water storage device 44 fills a fixed amount of liquid into the spray rod 42. As the fixed plate 41 rotates, the liquid can be continuously added to the spray rod 42 without the spray rod 42 having to carry a large amount of liquid during the rotation and spraying process. This avoids interference with the spraying process due to changes in the liquid weight. At the same time, only a fixed amount of liquid is stored in the spray rod 42, preventing the crystallization and blockage of the pipeline caused by long-term liquid storage and improving the service life of the device.

[0052] During the rotation of the atomization part 4, under the combined action of centrifugal force and air flow, the sprayed liquid droplets can be more evenly distributed in the treatment space, avoiding the over-concentration or sparseness of droplets in local areas. In the spraying area of the atomization part 4 rotating and spraying liquid, under the action of centrifugal force, the liquid is more widely scattered on the surface of the packing, forming a thinner and larger-area liquid film. At the same time, the packing fluctuates with the packing part 3, causing irregular undulations and folds in the liquid film, further increasing the gas-liquid contact area. The larger contact area increases the contact opportunities between organic molecules and the absorption liquid, improving the absorption efficiency. The rotation and fluctuation make the relative movement between the gas and the liquid more complex and intense. Under the action of the rotation and fluctuation of the packing, the gas continuously changes its flow direction and collides and contacts with the liquid more frequently. In a dynamic environment, both the gas and the liquid can carry out mass exchange more efficiently, accelerating the transfer rate of pollutants in the waste gas to the liquid phase.

[0053] In traditional static packings, there is often a situation of uneven gas-liquid distribution with more liquid near the tower wall and less liquid in the central area. However, with the packing that rotates and fluctuates with the strainer 31, the liquid can be more evenly distributed on the surface of the packing and flow in all directions under the combined action of rotation and fluctuation. At the same time, the gas will also be more evenly dispersed in the liquid due to the dynamic changes of the packing, avoiding the phenomenon of gas short-circuit and ensuring that the entire packing area can fully participate in the gas-liquid mass transfer process. For the fluctuations in the flow rates of the waste gas and the absorption liquid, this dynamic packing movement mode has better adaptability. When the flow rate increases, rotation and fluctuation can promote the faster mixing and dispersion of the gas and the liquid, avoiding insufficient gas-liquid contact caused by excessive flow rate; when the flow rate decreases, it can also maintain a certain gas-liquid mixing intensity through dynamic action, ensuring the stability of the treatment effect.

[0054] The above structure divides the spraying area into two regions, with alternating spraying of different intensities, making the distribution of the absorption liquid more uniform, avoiding local corrosion, maintaining the integrity and stability of the equipment structure. The design of the packing section 3 and the atomization section 4 in the spraying area realizes the advantages of strengthening gas-liquid mass transfer, improving gas-liquid distribution, and preventing blockage, significantly improving the waste gas treatment efficiency. Under the same treatment time and equipment volume, it can more effectively remove pollutants in the waste gas, making the discharged gas more easily meet the environmental protection standards. In actual use, this dynamic packing operation mode can flexibly adapt to the waste gas treatment requirements of different compositions, concentrations, and flow rates by adjusting the rotation speed and fluctuation amplitude. For waste gas with a higher concentration, the rotation speed and fluctuation amplitude can be appropriately increased to strengthen the mass transfer process; for waste gas with a simple composition and a lower concentration, the operation intensity can be reduced to save energy consumption.

[0055] The packing consumes a certain amount of energy during rotation and fluctuation, and this part of the energy mainly comes from the rotation power of the sieve 31. Therefore, the present invention is provided with a positioning member 5 to ensure the operation economy and energy saving of the equipment.

[0056] Reference Figure 2 and Figure 7 As shown in FIGS. and, the positioning member 5 includes a slider 51 slidably connected to the chute 45. The bottom end of the slider 51 is fixedly connected with a connecting rod 52, and the bottom end of the connecting rod 52 is fixedly connected with a limiting ball 53. When the sieve 31 rotates and fluctuates, it drives the leakage ring 34 to move synchronously. The limiting ball 53 can change the angle between the two with the slight vertical change of the fixed groove 341. However, due to the slider 51 embedded in the inner wall of the chute 45 at the top, the positioning member 5 will not have a vertical displacement. In the spraying area, the slider 51 and the chute 45 move relatively, and the slider 51 with a beveled side can also remove a small amount of impurities attached to the inner wall of the chute 45.

[0057] The packing section 3 and the atomization section 4 are connected by the positioning member 5. When the blocking block 32 contacts the rotating block 23, under the multiple influences of collision resistance, etc., the sieve 31 has a vertical fluctuation. The change range of the fluctuation close to the center of the circle is smaller than that of the outer wall. Therefore, the function of the positioning member 5 provided at the leakage ring 34 is to share the sieve 31 with a larger gravity during the fluctuation to ensure stability. When the packing fluctuates, the positioning member 5 as a connecting structure can evenly disperse the impact force generated by the shaking and impact of the packing, avoiding local deformation during the movement of the packing section 3 and affecting the stability of the overall structure. When the packing section 3 rotates, it will drive the entire positioning member 5 to rotate. A cleaning strip is provided on the outer wall of the connecting rod 52. The relative movement between the cleaning strip and the inner wall of the equipment will produce an effect similar to "wiping", which can remove a small amount of impurities that have adhered to the surface of the packing and achieve self-cleaning.
