Description

Technical Field

[0001] This invention relates to the field of viscose staple fiber production technology, specifically to a degassing device and degassing process for improving degassing efficiency in viscose staple fiber production. Background Technology

[0002] Viscose staple fiber is an important type of chemical fiber made from natural cellulose through processes such as alkalization and sulfonation to produce a viscose solution, which is then spun into fibers using a wet spinning process. During its production, the rheological properties and purity of the spinning solution directly affect fiber quality and spinning continuity. In the viscose solution preparation stage, the solution easily carries a large number of micron- to millimeter-sized air bubbles during stirring, pipeline transportation, and chemical reactions. If these bubbles are not effectively removed, they will cause problems such as spinneret blockage, fiber cross-section distortion, and increased surface hairiness in subsequent spinning processes. In severe cases, this can lead to fiber breakage or the formation of bubble pores, significantly reducing fiber mechanical properties and product yield. Therefore, efficient debubbling is a crucial pretreatment step to ensure fiber uniformity and spinning stability.

[0003] Currently, the industry generally uses static degassing tanks as the core degassing equipment, and these tanks are commonly used to remove bubbles from viscous liquids. The core of this device lies in the fixed packing tank structure inside the degassing tank, filled with shear-type packing material with a special spiral configuration. When the viscous liquid flows through the continuous flow channel of the spiral packing, the shearing effect of the packing surface geometry divides the liquid flow into thin layers, causing large bubbles to break down into microbubbles and increasing the gas-liquid contact area. Simultaneously, the extended path of the spiral flow channel significantly increases the fluid residence time, and combined with the turbulence effect induced by the packing, accelerates the collision, coalescence, and upward escape of bubbles, thus achieving highly efficient degassing. This technical solution effectively shortens the process cycle while ensuring degassing efficiency, and has become an important guarantee for maintaining the stability of the spinning process and fiber quality.

[0004] Existing degassing tanks employ an integral packing tank structure welded to the tank body. This design reveals significant drawbacks in practical applications: Firstly, after the spiral packing is removed, the junction between the bottom of the packing tank and the inner wall of the degassing tank creates a blind spot and mechanical dead zone due to structural limitations. Residual adhesive easily deposits and hardens here, gradually forming a difficult-to-remove hard scale layer. This not only reduces the flow channel cross-sectional area, affecting the shearing effect, but also alters the fluid dynamics, leading to a continuous decline in bubble cutting efficiency. Secondly, the fixed structure prevents modular maintenance of the packing tank. When corrosion or flow channel blockage occurs, the entire degassing tank must be disassembled or even destructively cut, resulting in a sharp increase in equipment maintenance costs and extended downtime for repairs. Over long-term operation, the cumulative effect of residues can cause progressive blockage of the flow channel, leading to a decrease in degassing efficiency and ultimately affecting the continuous and stable operation of the production system. Summary of the Invention

[0005] The purpose of this invention is to provide a degassing device and degassing process to improve the degassing efficiency in viscose staple fiber production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a degassing device for improving the degassing efficiency in viscose staple fiber production, comprising: a degassing barrel, a barrel cover detachably connected to the top of the degassing barrel, and a sealing component provided on the upper surface of the barrel cover at the top of the degassing barrel; The top of the degassing tank is detachably installed with a first packing tank. The two sides of the top inner wall of the first packing tank are fixedly connected to the bottom of the limiting rod. The top of the limiting rod passes through the tank cover. The two sides of the top of the limiting rod are provided with relatively movable clamping blocks. One side of the clamping block is provided with anti-slip texture. The other side of the clamping block is fixedly connected to one end of the clamping plate. The other end of the clamping plate is rotatably connected to the top of the fixing frame. The bottom of the fixing frame is fixedly connected to the upper surface of the tank cover. The middle of the clamping plate is rotatably connected to the moving plate. The side of the moving plate away from the limiting rod is connected to a drive component for driving the moving plate to move laterally. A second packing barrel is detachably connected to the lower side of the first packing barrel. A connecting assembly is provided between the top of the second packing barrel and the top of the first packing barrel to facilitate the installation and disassembly of the first and second packing barrels. The connecting assembly includes a connecting block. One side of the connecting block is fixedly connected to the outer ring surface of the bottom of the second packing barrel, and the other side of the connecting block is fixedly connected to a limiting block. A sliding rod is slidably sleeved on the top of the limiting block. Clamping rods are rotatably installed on both sides of the bottom of the limiting block. The bottom of the sliding rod is slidably connected to the top of the clamping rod. A connecting post is provided between the two clamping rods. One end of the connecting post is fixedly connected to the inner wall of the top of the second packing barrel. A pressure ring that can slide up and down is provided on the top of the sliding rod. The pressure ring is slidably installed on the outer ring surface of the bottom of the first packing barrel. One side of the upper surface of the pressure ring is connected to the driving assembly.

[0007] Preferably, the outer ring of the degassing tank is fixedly fitted with an installation ring, the bottom of the degassing tank is fixedly fitted with a discharge pipe, a feed pipe is fixedly installed on one side of the top of the degassing tank, a valve is fixedly fitted on the feed pipe, and a one-way valve is fixedly installed on the other side of the top of the degassing tank. The sealing assembly includes a connecting ear, which is arranged in a ring around the outer ring of the degassing tank and fixedly connected to the degassing tank. The connecting ear is rotatably connected to one end of the connecting plate through a limit pin, and the other end of the connecting plate is threadedly fitted with a pressing post. The bottom of the pressing post is slidably inserted into the pressing hole opened on the upper surface of the tank cover.

[0008] Preferably, the fixing frames are symmetrically arranged about the upper surface of the bucket lid. A fixing rod is fixedly installed on the side of the fixing frame near the limiting rod. Support frames are fixedly connected to the upper and lower ends of the moving plate. Both ends of the support frames are rotatably connected to one end of the connecting frame through connecting pins. The other end of the connecting frame is rotatably connected to the middle of the clamping plate through connecting pins. The clamping plate and the fixing frames are rotatably connected through fixing rods. The two fixing frames are fixedly connected through stabilizing rods.

[0009] Preferably, a connecting shaft is rotatably sleeved inside the stabilizer bar. The top end of the connecting shaft is fixedly connected to a handwheel, and the bottom end of the connecting shaft is fixedly connected to a drive gear. The drive gear meshes with the upper side of the transmission gear, and the lower side of the transmission gear meshes with the driven gear. The drive assembly includes a first threaded rod, both ends of which are rotatably sleeved on a fixed frame. The first threaded rod has two threads with opposite directions. Movable blocks are threaded onto both sides of the first threaded rod. The lower surface of the movable blocks is fixedly connected to the top of the insertion rod. The bottom of the insertion rod is slidably inserted into a slot on the upper surface of the bucket lid. The upper surface of the movable blocks is fixedly connected to one side of the movable plate through a pusher frame. The pusher frame is slidably installed in the fixed frame. The transmission gear is fixedly sleeved on the first threaded rod.

[0010] Preferably, the driven gear is fixedly sleeved on the top of the rotating shaft, and the bottom of the rotating shaft is rotatably sleeved inside the barrel cover. A drive meshing wheel is provided on the lower side of the driven gear. The drive meshing wheel engages with the driven meshing wheel through a meshing belt. The driven meshing wheel is fixedly connected to the top of the second threaded rod, and the bottom of the second threaded rod is threadedly sleeved with the pressure ring. The second threaded rod is rotatably sleeved inside the limiting sleeve fixedly connected to the upper surface of the barrel cover.

[0011] Preferably, the inner ring of the pressure ring is slidably mounted on the semi-cylinder on both sides, the semi-cylinder is fixedly connected to the outer wall of the first packing barrel, the top of the clamping rod is slidably connected to the inclined surface at the bottom of the slide rod through the arc surface opened on it, the bottom of the clamping rod is fixedly connected to the end of the reset spring, and the clamping rod is rotatably connected to the limiting block through a fixing pin. The bottom of both the first packing barrel and the second packing barrel are provided with several through holes.

[0012] A degassing process for a degassing device to improve degassing efficiency in viscose staple fiber production includes the following steps: Spiral packing is pre-filled inside the first and second packing barrels. The top of the limiting rod of the first packing barrel is inserted through the lower surface of the barrel cover, positioning the limiting rod between the two clamping blocks. Simultaneously, the second packing barrel is placed at the bottom of the first packing barrel, with the connecting column positioned between the two clamping rods. Driven by the drive assembly, the moving plate moves away from the limiting rod. The rotational connection between the moving plate and the clamping plate, and between the clamping plate and the fixed frame, causes the two clamping plates to move the clamping blocks towards each other. Under the clamping action of the two clamping blocks, the limiting rod is fixed in place, thus limiting and fixing the first packing barrel. Simultaneously, the drive assembly causes the pressure ring to slide downwards along the outer wall of the first packing barrel. The pressure ring gradually contacts the sliding rod, pressing the top of the sliding rod downwards. The bottom of the sliding rod slides into contact with the top of the clamping rod. Because the clamping rod is rotatably mounted on the limiting rod... Within the block, the two clamping rods move towards each other, thereby clamping and fixing the connecting column, and finally limiting and fixing the second packing barrel. Then, when the first and second packing barrels are placed into the degassing barrel, the barrel lid contacts the top of the degassing barrel. Finally, the sealing component seals the degassing barrel and the barrel lid. When in use, the adhesive liquid can be introduced into the degassing barrel. Through the spiral packing inside the first and second packing barrels, the disturbance and shearing effect are enhanced, improving the bubble separation efficiency. When the degassing barrel, the first packing barrel, and the second packing barrel need to be cleaned, first contact the sealing limit of the sealing component, and the barrel lid can be removed. Then, by controlling the drive component to move in the reverse direction, the two clamping blocks and the two clamping rods move in opposite directions, finally releasing the limit rods and the connecting column, and then the degassing barrel, the first packing barrel, and the second packing barrel can be separated for subsequent cleaning. Preferably, when the degassing tank needs to be used, the degassing tank is fixed to the external equipment by the mounting ring fixedly fitted on its outer ring surface. The degassed material is discharged through the discharge pipe connected to the bottom of the degassing tank. The top of the degassing tank is connected to the feed pipe, and a valve is installed on the feed pipe. The installed valve facilitates connection with external management and control of material flow. When the tank lid is attached to the top of the degassing tank, the first and second packing tanks filled with spiral structure packing are inside the degassing tank. To increase the sealing of the connection, the connecting plate can be rotated towards the tank lid, and then the pressing post connected to the internal thread of the connecting plate can be twisted to make the pressing post slide into the pressing hole opened near the top of the tank lid until the pressing post cannot be twisted. At this time, the tank lid is tightly closed on the top of the degassing tank. During the degassing process, the gas inside the degassing tank is discharged to the outside through the one-way valve to avoid excessive internal pressure.

[0013] Preferably, when the first filling tank needs to be installed, the top of the limiting rod fixedly connected to its top is first passed through the tank cover, so that the limiting rod is positioned between the two clamping blocks. At this time, by turning the handwheel, the handwheel drives the connecting shaft to rotate under the limitation of the stabilizing rod, thereby driving the drive gear to rotate. The drive gear drives the driven gear to rotate through the meshing of the transmission gear. At the same time, the rotation of the transmission gear will drive the first threaded rod fixedly sleeved on it to rotate. The first threaded rod has two threads with opposite directions of rotation, so that the rotation of the first threaded rod causes the two moving blocks to move. The moving blocks slide with the insertion rod and the slot, thereby causing the moving blocks to move along the axis of the first threaded rod. The moving blocks move in opposite directions, causing the pusher frame fixedly connected to their upper side to move synchronously. The pusher frame is fixedly connected to the moving plate, which in turn causes the two moving plates to move in opposite directions. The moving plates move away from the limit rods. The moving plates are rotatably connected to the connecting frame through the support frames on their upper and lower sides, causing the connecting frame to pull the clamping plate. One end of the clamping plate is rotatably connected to the fixed rod on the fixed frame, and the other end of the clamping plate moves towards the limit rods, causing the two limit rods to drive the clamping blocks to clamp and fix the limit rods, thereby fixing and limiting the first packing barrel. When it is necessary to disassemble the first packing barrel, the handwheel can be turned in the opposite direction. The second packing barrel is installed at the same time as the first packing barrel is installed.

[0014] Preferably, when the second packing barrel needs to be installed, it is placed at the bottom of the first packing barrel beforehand, with the connecting column positioned between the two clamping rods. When the drive assembly is running, the driven gear drives the drive meshing wheel to rotate through the shaft connection. The drive meshing wheel drives the driven meshing wheel to rotate under the meshing transmission of the meshing belt. The driven meshing wheel is fixedly sleeved on the top of the second threaded rod. The second threaded rod is rotatably installed on the top of the barrel cover. The bottom of the second threaded rod is threadedly connected to the pressure ring, thereby driving the pressure ring to move. The pressure ring slides downward under the limit of the semi-cylinder, which in turn causes the pressure ring to press the sliding rod to slide downward under the limit of the limiting block. The sliding rod is slidably connected to the clamping rod through its bottom, thereby causing the two clamping rods to move towards each other while compressing the return spring. This causes the clamping rod to limit and fix the connecting column, and the connecting column is fixedly connected to the inner wall of the second packing barrel, thus completing the fixation of the second packing barrel. When the handwheel is rotated in the reverse direction, the limit of the clamping rod on the connecting column can be indirectly released, facilitating the disassembly and subsequent cleaning of the second packing barrel.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By adopting a layered, detachable packing tank design (first and second packing tanks) and a linkage drive assembly, modular and rapid assembly and disassembly of the packing is achieved. This structure completely solves the problem of cleaning dead zones caused by scale buildup at the bottom of traditional fixed packing tanks, and avoids flow channel blockage and shear efficiency reduction caused by residual adhesive caking. Simultaneously, maintenance can be completed without overall disassembly or destructive cutting, significantly shortening downtime for maintenance and ensuring long-term stable operation of the degassing equipment and maintaining high-efficiency bubble separation capabilities.

[0016] 2. The layered packing tanks are filled with helical packing material, which extends the residence time of the viscous liquid and enhances the turbulence effect through a two-stage flow channel. As the viscous liquid flows sequentially through the first and second packing tanks, it is divided into thinner liquid layers by the continuous shearing action of the helical packing material, promoting bubble refinement and accelerating coalescence and buoyancy. The two-stage structure further optimizes the fluid dynamics distribution, improves bubble cutting efficiency and escape velocity, reduces spinneret blockage and fiber defects at the source, and ensures fiber cross-sectional uniformity and mechanical properties.

[0017] 3. The integrated sealing assembly and mechanical linkage drive mechanism, via a handwheel-driven gear set, synchronously control the movement of the clamping block, pressure ring, and slide bar, achieving precise positioning and sealing of the packing barrel. Combined with a one-way valve and waste gas condensation and recovery system, it avoids harmful gas leakage while efficiently degassing, ensuring a safe process environment. This design simplifies the operation process, reduces human error, improves the controllability of the degassing process, and provides a reliable guarantee for continuous production.

[0020] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-9This invention provides a technical solution: A, comprising: a degassing device and degassing process for improving degassing efficiency in viscose staple fiber production, comprising: a degassing tank 1, a tank cover 2 detachably connected to the top of the degassing tank 1, thereby allowing operation inside the degassing tank 1 through the detachable tank cover 2, a sealing component provided on the upper surface of the tank cover 2, the sealing component being provided to seal the degassing tank 1 during use, a first packing tank 3 detachably installed at the top of the degassing tank 1, the two sides of the top inner wall of the first packing tank 3 being fixedly connected to the bottom end of a limiting rod 4, the top end of the limiting rod 4 penetrating the tank cover 2, and an opening on the tank cover 2 corresponding to the limiting rod 4. The corresponding through hole limits the positioning rod 4. The top two sides of the positioning rod 4 are equipped with relatively movable clamping blocks 5. One side surface of the clamping block 5 has anti-slip texture to improve the stability of the clamping block 5 during clamping with the positioning rod 4. The other side surface of the clamping block 5 is fixedly connected to one end of the clamping plate 6. The other end of the clamping plate 6 is rotatably connected to the top of the fixing frame 7. The bottom of the fixing frame 7 is fixedly connected to the upper surface of the bucket lid 2. The middle part of the clamping plate 6 is rotatably connected to the moving plate 8. A drive assembly for driving the lateral movement of the moving plate 8 is connected to the side of the moving plate 8 away from the positioning rod 4. The first filling... A second packing tank 9 is detachably connected to the lower side of the material tank 3. By setting the first packing tank 3 and the second packing tank 9, the degassing effect is further improved. A connecting component is provided between the top of the second packing tank 9 and the top of the first packing tank 3 to facilitate the installation and disassembly of the first packing tank 3 and the second packing tank 9. The connecting component improves the installation and disassembly efficiency of the first packing tank 3 and the second packing tank 9. The connecting component includes a connecting block 10. One side of the connecting block 10 is fixedly connected to the outer ring surface of the bottom of the first packing tank 3, and the other side of the connecting block 10 is fixedly connected to a limiting block 11. A sliding rod 12 is slidably sleeved on the top. Clamping rods 13 are rotatably installed on both sides of the bottom of the limiting block 11. The bottom of the sliding rod 12 is slidably connected to the top of the clamping rods 13. A connecting post 14 is provided between the two clamping rods 13. One end of the connecting post 14 is fixedly connected to the inner wall of the top of the second packing barrel 9, so that the clamping rods 13 limit the connecting post 14, thereby fixing and limiting the second packing barrel 9. A pressure ring 15 that can slide up and down is provided on the top of the sliding rod 12. The pressure ring 15 is slidably installed on the outer ring surface of the bottom of the first packing barrel 3. One side of the upper surface of the pressure ring 15 is connected to the drive assembly.Spiral packing is pre-filled inside the first packing barrel 3 and the second packing barrel 9. The top of the limiting rod 4 of the first packing barrel 3 is inserted through the lower surface of the barrel cover 2, so that the limiting rod 4 is between the two clamping blocks 5. At this time, the first packing barrel 3 is below the barrel cover 2. At the same time, the second packing barrel 9 is placed at the bottom of the first packing barrel 3, and the connecting column 14 is between the two clamping rods 13. Then, driven by the drive assembly, the moving plate 8 moves away from the limiting rod 4, thereby achieving rotational connection between the moving plate 8 and the clamping plate 6 and the clamping plate. Under the rotational connection of clamping plate 6 and fixed frame 7, the two clamping plates 6 drive the clamping blocks 5 to move towards each other. Thus, under the clamping action of the two clamping blocks 5, the limiting rod 4 is fixed and limited, thereby limiting and fixing the first packing barrel 3. While the drive assembly is running, it will drive the pressure ring 15 to slide downward along the outer wall of the first packing barrel 3. The pressure ring 15 will gradually contact the slide rod 12 and press the top of the slide rod 12 downward. The bottom of the slide rod 12 is slidably connected to the top of the clamping rod 13. Since the clamping rod 13 is rotatably installed in the limiting block 11, the two clamping rods will... 13 move towards each other, causing the clamping rod 13 to clamp and fix the connecting column 14, ultimately limiting and fixing the second packing barrel 9. Then, the first packing barrel 3 and the second packing barrel 9 are placed into the degassing barrel 1, with the barrel cover 2 contacting the top of the degassing barrel 1. Finally, the sealing assembly seals the degassing barrel 1 and the barrel cover 2. In use, the adhesive liquid can be introduced into the degassing barrel 1. Through the spiral packing inside the first packing barrel 3 and the second packing barrel 9, the disturbance and shearing effects are enhanced, improving the bubble separation efficiency. When it is necessary to degas the first packing barrel 1, the first packing barrel 3, and the second packing barrel 9, the first packing barrel 3 and the second packing barrel 9 can be used to further degas the degassing barrel 1. When cleaning the second packing tank 9, firstly release the sealing limit of the sealing component, then remove the tank cover 2. Then, by controlling the drive component in reverse, the two clamping blocks 5 and the two clamping rods 13 can move in opposite directions, finally releasing the limit rod 4 and the connecting column 14. This allows the degassing tank 1, the first packing tank 3, and the second packing tank 9 to be separated, facilitating subsequent cleaning, avoiding cleaning dead corners, and eliminating the need to completely disassemble or even destructively cut the degassing tank 1, which would otherwise lead to a significant increase in equipment maintenance costs and a longer downtime maintenance cycle.

[0022] Example 2: Based on Example 1, a mounting ring 16 is fixedly fitted on the outer ring surface of the degassing tank 1. The mounting ring 16 facilitates the fixing of the degassing tank 1 to external equipment. A discharge pipe 17 is fixedly fitted on the bottom of the degassing tank 1. A feed pipe 18 is fixedly installed on one side of the top of the degassing tank 1. A valve 19 is fixedly fitted on the feed pipe 18. A one-way valve 20 is fixedly installed on the other side of the top of the degassing tank 1. The one-way valve 20 is used for venting air inside the degassing tank 1. The sealing assembly includes a connecting ear 21. The connecting ear 21 is arranged in a ring around the outer ring surface of the degassing tank 1 and is fixedly connected to the degassing tank 1. The connecting ear 21 is rotatably connected to one end of the connecting plate 22 through a limiting pin. The other end of the connecting plate 22 is threadedly fitted with a pressing post 23. The bottom of the pressing post 23 is slidably inserted into the pressing hole opened on the upper surface of the tank cover 2. When the degassing tank 1 is to be used, it is fixed to the external equipment by the mounting ring 16 fixedly fitted on its outer ring surface. The degassed material is discharged through the discharge pipe 17 connected to the bottom of the degassing tank 1. The top of the degassing tank 1 is connected to the feed pipe 18, and a valve 19 is installed on the feed pipe 18. The installed valve 19 facilitates connection with external pipelines and controls the flow rate of the material. When the tank cover 2 is placed on the top of the degassing tank 1, the first packing tank 3 and the second packing tank 9, which are filled with spiral structure packing, are inside the degassing tank 1. In order to increase the sealing of the connection, the connecting plate 22 can be rotated towards the tank cover 2, and the crimping post 23 connected to the internal thread of the connecting plate 22 can be twisted to bring the crimping post 23 closer to the top of the tank cover 2. Slide the cylinder through the pressure hole until the pressing post 23 cannot be turned. At this point, tighten the lid 2 onto the top of the degassing tank 1. During the degassing process, the gas inside the degassing tank 1 is discharged outward through the one-way valve 20 to prevent excessive internal pressure. Simultaneously, the one-way valve 20 is connected to the input of the external condenser, the output of the condenser is connected to the input of the gas-liquid separator, and the output of the gas-liquid separator is connected to the output of the atmospheric jet. The waste gas and water vapor generated during degassing flow away from the top of the degassing tank 1 through a sealed pipe, first entering the condenser where cold water cools them, causing the harmful gases and water vapor to condense into liquid. Then, they enter the gas-liquid separator where gravity separates the liquid from the remaining gas. Finally, the remaining waste gas is drawn in by the atmospheric jet with high-speed water flow and negative pressure, mixed with air, and diluted to a safe concentration before being discharged. The entire process involves triple treatment—condensation and liquefaction, physical separation, and dynamic dilution—to ensure that harmful gases are discharged in compliance with standards while simultaneously achieving resource recovery.

[0023] Example 3: Based on Example 2, the fixing frame 7 is symmetrically arranged about the upper surface of the bucket lid 2. A fixing rod 24 is fixedly installed on the side of the fixing frame 7 near the limiting rod 4. Support frames 25 are fixedly connected to the upper and lower ends of the moving plate 8. Both ends of the support frame 25 are rotatably connected to one end of the connecting frame 26 through connecting pins. The other end of the connecting frame 26 is rotatably connected to the middle of the clamping plate 6 through connecting pins. The clamping plate 6 and the fixing frame 7 are rotatably connected through the fixing rod 24. The two fixing frames 7 are fixedly connected through the stabilizing rod 27. A connecting shaft 31 is rotatably sleeved inside the stabilizing rod 27. The stabilizing rod 27 limits the connecting shaft 31, thereby improving its stability during rotation. The top end of the connecting shaft 31 is fixedly connected to the handwheel 32, and the bottom end of the connecting shaft 31 is fixedly connected to the drive gear 33. The drive gear 33 meshes with the upper side of the transmission gear 34, and the lower side of the transmission gear 34 meshes with the driven gear 35. The drive assembly includes a first threaded rod 28, both ends of which are rotatably sleeved on the fixed frame 7. The fixed frame 7 provides stable support for the first threaded rod 28. The first threaded rod 28 has two threads with opposite directions of rotation. Movable blocks 29 are threadedly sleeved on both sides of the first threaded rod 28. The lower surface of the movable block 29 is fixedly connected to the top of the insertion rod 43. The bottom of the insertion rod 43 is slidably inserted into a slot on the upper surface of the bucket lid 2. The slot limits the insertion rod 43. The upper surface of the movable block 29 is fixedly connected to one side of the movable plate 8 through a pusher 30. The pusher 30 is slidably installed in the fixed frame 7. The transmission gear 34 is fixedly sleeved on the first threaded rod. When the first filling barrel 3 needs to be installed, the top of the limiting rod 4, which is fixedly connected to its top, passes through the barrel cover 2, so that the limiting rod 4 is between the two clamping blocks 5. At this time, by turning the handwheel 32, the handwheel 32 drives the connecting shaft 31 to rotate under the limit of the stabilizing rod 27, thereby driving the drive gear 33 to rotate. The drive gear 33 drives the driven gear 35 to rotate through the meshing transmission gear 34. At the same time, the rotation of the transmission gear 34 will drive the first threaded rod 28 fixedly sleeved on it to rotate. The first threaded rod 28 has two threads with opposite directions of rotation, so that the rotation of the first threaded rod 28 causes the two moving blocks 29 to move. The moving blocks 29 slide with the slot through the insertion rod 43, and then the moving blocks 29 move along the first threaded rod 28. The threads 28 move in opposite directions along their axes, causing the moving block 29 to move synchronously with the push frame 30 fixedly connected to its upper side. One end of the push frame 30 is fixedly connected to the moving plate 8, causing the two moving plates 8 to move towards each other. The moving plates 8 move away from the limiting rod 4. The moving plates 8 are rotatably connected to the connecting frame 26 via the support frames 25 on their upper and lower sides, causing the connecting frame 26 to pull the clamping plate 6. One end of the clamping plate 6 is rotatably connected to the fixing rod 24 on the fixing frame 7, while the other end of the clamping plate 6 moves towards the limiting rod 4, causing the two limiting rods 4 to drive the clamping block 5 to tighten and fix the limiting rods 4, thereby fixing and limiting the first packing barrel 3, so that the first packing barrel 3 is installed below the barrel cover 2. When it is necessary to disassemble the first packing barrel 3...Simply turn the handwheel 32 in the opposite direction. The second packing tank 9 is installed simultaneously with the first packing tank 3, achieving synchronized installation and removal of both, improving maintenance efficiency and consequently enhancing subsequent degassing efficiency.

[0024] Example 4: Based on Example 3, the driven gear 35 is fixedly sleeved on the top of the rotating shaft 36, and the bottom of the rotating shaft 36 is rotatably sleeved inside the bucket cover 2. The bucket cover 2 limits the rotation of the rotating shaft 36. A drive meshing wheel 37 is provided on the lower side of the driven gear 35. The drive meshing wheel 37 meshes with the driven meshing wheel 39 through the meshing belt 38. The driven meshing wheel 39 is fixedly connected to the top of the second threaded rod 40. The bottom of the second threaded rod 40 is threadedly sleeved with the pressure ring 15. The second threaded rod 40 is rotatably sleeved in the limiting sleeve fixedly connected to the upper surface of the bucket cover 2. The inner ring surface of the pressure ring 15 is slidably mounted on both sides. The semi-cylinder 41 is fixedly connected to the outer wall of the first packing barrel 3. The top of the clamping rod 13 is slidably connected to the inclined surface at the bottom of the slide rod 12 through the arc surface opened on it. The bottom of the clamping rod 13 is fixedly connected to the end of the return spring 42. The clamping rod 13 is rotatably connected to the limiting block 11 through a fixing pin. The bottom of both the first packing barrel 3 and the second packing barrel 9 are provided with several through holes to facilitate the flow of materials. When the second packing barrel 9 needs to be installed, it is placed at the bottom of the first packing barrel 3 beforehand, and the connecting column 14 is positioned between the two clamping rods 13. During operation of the drive assembly, the driven gear 35 drives the drive engagement wheel 37 to rotate via the connection of the rotating shaft 36. The drive engagement wheel 37 drives the driven engagement wheel 39 to rotate under the meshing transmission of the engagement belt 38. The driven engagement wheel 39 is fixedly sleeved on the top of the second threaded rod 40. The second threaded rod 40 is rotatably mounted on the top of the bucket cover 2. The bottom of the second threaded rod 40 is threadedly connected to the pressure ring 15, thereby driving the pressure ring 15 to move. The pressure ring 15 slides downward under the limitation of the semi-cylinder 41, which in turn causes the pressure ring 15 to press the slide rod 12 to slide downward under the limitation of the limiting block 11. 2. Through the sliding connection between the bottom inclined surface and the top arc surface of the clamping rod 13, the two clamping rods 13 move towards each other while compressing the return spring 42. Under the limitation of the fixed pin, the two clamping rods 13 move towards each other, limiting and fixing the connecting column 14. The connecting column 14 is fixedly connected to the inner wall of the second packing barrel 9, thus completing the fixation of the second packing barrel 9. When the handwheel 32 rotates in the opposite direction, the slide rod 12 slides upward, and the return spring 42 generates a reverse elastic force, which can indirectly release the limitation of the clamping rod 13 on the connecting column 14, making it easier to disassemble the second packing barrel 9 and clean it later.
