Description
Technical Field
[0001] The present invention relates to the technical field of viscose staple fiber production, and specifically to a defoaming device and production process for improving the defoaming efficiency in viscose staple fiber production. Background Art
[0002] Viscose staple fiber is an important chemical fiber variety formed by wet spinning after making viscose solution from natural cellulose through processes such as alkalization and sulfonation. During its production process, the rheological properties and purity of the spinning solution directly affect fiber quality and spinning continuity. In the viscose solution preparation stage, the solution is prone to entrain a large number of bubbles ranging from micrometers to millimeters during stirring, pipeline transportation, and chemical reactions. If such bubbles are not effectively removed, they will cause problems such as spinneret hole blockage, fiber cross-section distortion, and a significant increase in surface hairiness in the subsequent spinning process. In severe cases, it will lead to filament breakage or the formation of bubble hole defects, significantly reducing the fiber mechanical properties and product qualification rate. Therefore, efficient defoaming is a key pretreatment link to ensure fiber uniformity and spinning stability.
[0003] Currently, the industry generally uses a static defoaming barrel as the core defoaming equipment, and currently generally uses a defoaming barrel device to remove bubbles from viscose solution. The core of this device lies in the fixed packing barrel structure arranged inside the defoaming barrel, and the packing barrel is filled with shear-type packing with a special spiral configuration. When the viscose solution flows through the continuous flow channel of the spiral packing, due to the shearing action of the surface geometric structure of the packing, the liquid flow is divided into thin layer states, prompting large bubbles to break into microbubbles and increasing the gas-liquid contact area. At the same time, the extended path of the spiral flow channel significantly increases the fluid residence time. Combining with the turbulent effect induced by the packing, it accelerates the collision coalescence and floating out of bubbles, thereby achieving efficient defoaming. This technical solution effectively shortens the process cycle while ensuring defoaming efficiency, and has become an important guarantee for maintaining the stability of the spinning process and fiber quality.
[0004] The existing defoaming barrel adopts an integral packing barrel structure welded and fixed to the barrel body, which exposes significant defects in practical applications: on the one hand, after the spiral packing is taken out, due to structural limitations, a visual blind area and mechanical dead angle are formed at the junction of the bottom of the packing barrel and the inner wall of the defoaming barrel, and residual viscose solution is prone to deposit and harden here, gradually forming a hard scale layer that is difficult to remove. This not only reduces the cross-sectional area of the flow channel and affects the shearing effect, but also changes the hydrodynamic characteristics, resulting in a continuous decline in bubble cutting efficiency; on the other hand, the fixed structure makes the packing barrel unable to achieve modular maintenance. When the packing barrel is corroded or the flow channel is blocked, it is necessary to disassemble the entire defoaming barrel or even perform destructive cutting, resulting in a sharp increase in equipment maintenance costs and an extension of the shutdown and maintenance cycle. During long-term operation, the cumulative effect of residues will cause progressive blockage of the flow channel, resulting in a decrease in defoaming efficiency and ultimately affecting the continuous and stable operation of the production system. Summary of the Invention

One end of the connecting ear is rotatably connected with one end of a connecting plate through a limit pin. The other end of the connecting plate is threadedly sleeved with a pressing column. The bottom of the pressing column is slidably inserted into a pressing hole opened on the upper surface of the barrel cover.
[0008] Preferably, the fixing frames are symmetrically arranged on the upper surface of the barrel cover. A fixing rod is fixedly installed on the side of the fixing frame close to the limiting rod. The upper and lower ends of the moving plate are fixedly connected with support frames. Both ends of the support frames are rotatably connected with one end of a connecting frame through a connecting pin. The other end of the connecting frame is rotatably connected with the middle of the clamping plate through a connecting pin. The clamping plate is rotatably connected with the fixing frame through the fixing rod. The two fixing frames are fixedly connected through a stabilizing rod.
[0009] Preferably, a connecting shaft is rotatably sleeved inside the stabilizer bar. The top end of the connecting shaft is fixedly connected to the handwheel, and the bottom end of the connecting shaft is fixedly connected to the driving gear. The driving gear meshes and drives with the upper side of the transmission gear, and the lower side of the transmission gear meshes with the driven gear. The driving assembly includes a first threaded rod. Both ends of the first threaded rod are rotatably sleeved on the fixed frame. Two sections of threads with opposite helix directions are provided on the first threaded rod. Moving blocks are threadedly sleeved on both sides of the first threaded rod. The lower surface of the moving block is fixedly connected to the top of the insertion rod. The bottom of the insertion rod is slidably inserted into the slot opened on the upper surface of the barrel cover. The upper surface of the moving block is fixedly connected to one side of the moving plate through a pushing frame. The pushing frame is slidably installed inside 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 end of the rotating shaft. The bottom end of the rotating shaft is rotatably sleeved inside the barrel cover. A driving meshing wheel is arranged below the driven gear. The driving meshing wheel meshes and drives with the driven meshing wheel through a meshing belt. The driven meshing wheel is fixedly connected to the top of the second threaded rod. The bottom of the second threaded rod is threadedly sleeved with a pressing ring. The second threaded rod is rotatably sleeved inside the limiting sleeve fixedly connected to the upper surface of the barrel cover.
[0011] Preferably, both sides of the inner circumferential surface of the pressing ring are slidably installed on the semi-cylinder. The semi-cylinder is fixedly connected to the outer wall of the first stuffing barrel. The top of the clamping rod is slidably connected to the inclined surface opened at the bottom of the sliding rod through the arc surface opened thereon. The bottom of the clamping rod is fixedly connected to the end of the return spring. The clamping rod is rotatably connected to the limiting block through a fixing pin. A plurality of through holes are opened at the bottoms of the first stuffing barrel and the second stuffing barrel.
[0012] A production process of a defoaming device for improving the defoaming efficiency of viscose staple fiber production includes the following steps: Pre-fill the fillers with a spiral structure inside the first filler barrel and the second filler barrel. Pass the top end of the limiting rod of the first filler barrel through and sleeved from the lower surface of the barrel cover, so that the limiting rod is between the two clamping blocks. At the same time, place the second filler barrel at the bottom of the first filler barrel, and the connecting column is between the two clamping rods. At this time, through the drive of the drive assembly, the moving plate moves away from the limiting rod. Thus, under the rotational connection between the moving plate and the clamping plate and the rotational connection between the clamping plate and the fixed frame, the two clamping plates drive the clamping blocks to move towards each other. Thus, under the clamping action of the two clamping blocks, the limiting rod is fixed and limited, and then the first filler barrel is limited and fixed. While the drive assembly is running, it will drive the pressure ring to slide down along the outer wall of the first filler barrel. The pressure ring will gradually contact the sliding rod and press down the top of the sliding rod. The bottom of the sliding rod is slidably connected to the top of the clamping rod. Since the clamping rod is rotatably installed in the limiting block, the two clamping rods will move towards each other, and then the clamping rod will clamp and fix the connecting column, and finally the second filler barrel is limited and fixed. Then, when the first filler barrel and the second filler barrel are placed in the degassing barrel, the barrel cover contacts the top of the degassing barrel. Finally, through the sealing assembly, the degassing barrel and the barrel cover are sealed. When in use, the adhesive liquid can be introduced into the degassing barrel. Through the spiral fillers inside the first filler barrel and the second filler barrel, the disturbance and shearing effects are enhanced, and the bubble separation efficiency is improved. When it is necessary to clean the degassing barrel, the first filler barrel and the second filler barrel, first release the sealing limit of the sealing assembly, then the barrel cover can be taken out first, and then by reversely controlling the movement of the drive assembly, the two clamping blocks and the two clamping rods can move away from each other, and finally the limitation of the limiting rod and the connecting column is released, and then the degassing barrel, the first filler barrel and the second filler barrel can be separated from each other, which is convenient for subsequent cleaning; Preferably, when the degassing barrel needs to be used, the degassing barrel is fixed to external equipment through the mounting ring frame fixedly sleeved on its outer circumferential surface. The degassed material is discharged through the discharge pipe communicated with the bottom of the degassing barrel. The top of the degassing barrel is communicated with a feed pipe, and a valve is installed on the feed pipe. Through the installed valve, on the one hand, it is convenient to connect with external management, and on the other hand, it is convenient to control the flow rate of the material. When the barrel cover is connected to the top of the degassing barrel, the first filler barrel and the second filler barrel filled with spiral structure fillers are inside the degassing barrel. In order to increase the connection tightness, the connecting plate can be rotated towards the barrel cover, and then by twisting the crimping column threadedly sleeved inside the connecting plate, the crimping column can slide into the pressing hole opened at the top of the barrel cover until the crimping column cannot be twisted. At this time, the barrel cover is tightly covered on the top of the degassing barrel. During the degassing process, the gas inside the degassing barrel is discharged outwards through the one-way valve to avoid excessive internal pressure.
[0013] Preferably, when the first filler bucket needs to be installed, first pass the top of the limiting rod fixedly connected to its top through the bucket lid so that the limiting rod is between the two clamping blocks. At this time, turn the handwheel. The handwheel drives the connecting shaft to rotate under the limitation of the stabilizing rod, thereby driving the driving gear to rotate. The driving gear drives the driven gear to rotate through the meshing transmission of the transmission gear. While the transmission gear rotates, it will drive the first threaded rod fixedly sleeved thereon to rotate. The first threaded rod is provided with two threads with opposite helix directions. Therefore, under the rotation of the first threaded rod, the two moving blocks move. The moving blocks are in sliding fit with the insertion slots through the insertion rods, and then the moving blocks move towards each other along the axis direction of the first threaded rod. The moving blocks drive the pushing frames fixedly connected to the upper sides thereof to move synchronously. The pushing frames are fixedly connected to the moving plates, and then the two moving plates move towards each other. The moving plates move away from the limiting rod. The moving plates are rotatably connected to the connecting frames through the support frames on the upper and lower sides thereof, so that the connecting frames pull the clamping plates to move. 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 direction close to the limiting rod, so that the two limiting rods drive the clamping blocks to clamp and fix the limiting rod, and then the first filler bucket is fixed and limited. When the first filler bucket needs to be disassembled, reverse the handwheel. The installation of the first filler bucket is carried out simultaneously with the installation of the second filler bucket.
[0014] Preferably, when the second filler bucket needs to be installed, first place the second filler bucket at the bottom of the first filler bucket and make the connecting column between the two clamping rods. When the driving assembly operates, the driven gear drives the driving meshing wheel to rotate through the connection of the rotating shaft. The driving meshing wheel drives the driven meshing wheel to rotate through 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 bucket lid. The bottom of the second threaded rod is threadedly connected to the pressure ring, so that the pressure ring can be driven to move. The pressure ring slides downward under the limitation of the semi-cylinder, and then the pressure ring presses the sliding rod to slide downward under the limitation of the limiting block. The sliding rod is slidably connected to the clamping rod through its bottom, so that the two clamping rods move towards each other while compressing the return spring, and then the clamping rods limit and fix the connecting column. The connecting column is fixedly connected to the inner wall of the second filler bucket, and finally the fixing of the second filler bucket is completed. When the handwheel rotates in the reverse direction, the limitation of the clamping rod on the connecting column can be indirectly released, which is convenient for the disassembly of the second filler bucket and subsequent cleaning.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By adopting a layered and detachable packing barrel design (the first packing barrel and the second packing barrel) and an interlocking drive assembly, modular and rapid disassembly and assembly of the packing are achieved. This structure completely solves the problem of cleaning dead corners formed by scale accumulation at the bottom of the traditional fixed packing barrel, avoiding the blockage of the flow channel and the attenuation of shear efficiency caused by the hardening of the residual adhesive liquid. At the same time, maintenance can be completed without overall disassembly or destructive cutting, significantly shortening the shutdown maintenance cycle, ensuring the long-term stable operation of the degassing equipment, and maintaining high-efficiency bubble separation ability.
[0016] 2. The layered packing barrel is filled with spiral configuration packing, which extends the residence time of the adhesive liquid through a two-stage flow channel and strengthens the turbulence effect. When the adhesive liquid flows through the first and second packing barrels in sequence, it is divided into thinner liquid layers under the continuous shearing action of the spiral packing, promoting the refinement of bubbles and accelerating the coalescence and floating. The two-stage structure further optimizes the hydrodynamic distribution, improves the bubble cutting efficiency and the escape speed, reduces the blockage of the spinneret holes and fiber defects from the root cause, and ensures the uniformity of the fiber cross-section and the mechanical properties.
[0017] 3. An integrated sealing component and a mechanical interlocking drive mechanism are combined. By driving the gear set with a handwheel to synchronously control the movement of the clamping block, the pressure ring and the slide rod, accurate positioning and sealing compression of the packing barrel are achieved. Combining a one-way valve with an exhaust gas condensation recovery system can avoid the leakage of harmful gases while achieving efficient degassing, ensuring the safety of the process environment. This design simplifies the operation process, reduces human operation errors, improves the controllability of the degassing process, and provides a reliable guarantee for continuous production.

All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0021] Embodiment 1: Please refer to Figures 1-9, the present invention provides a technical solution: a kind of A, including: a defoaming device and production process for improving the defoaming efficiency of viscose staple fiber production, including: a defoaming barrel 1, the top of the defoaming barrel 1 is detachably connected with a barrel cover 2, so that the inside of the defoaming barrel 1 can be operated through the detachable barrel cover 2. A sealing component is arranged on the upper surface of the barrel cover 2 at the top of the defoaming barrel 1. The setting of the sealing component can seal the defoaming barrel 1 during use. A first filler barrel 3 is detachably installed at the inner top of the defoaming barrel 1. Both sides of the inner wall at the top of the first filler barrel 3 are fixedly connected with the bottom ends of the limiting rods 4. The top ends of the limiting rods 4 penetrate through the barrel cover 2, and through holes corresponding to the limiting rods 4 are opened on the barrel cover 2 to limit the limiting rods 4. Clamping blocks 5 that can move relatively are arranged on both sides of the top of the limiting rods 4. Anti-slip patterns are arranged on one side surface of the clamping blocks 5 to improve the stability during the clamping process between the clamping blocks 5 and the limiting rods 4. The other side surface of the clamping blocks 5 is fixedly connected with one end of a clamping plate 6. The other end of the clamping plate 6 is rotatably connected with the top of a fixed frame 7. The bottom of the fixed frame 7 is fixedly connected with the upper surface of the barrel cover 2. The middle of the clamping plate 6 is rotatably connected with a moving plate 8. A driving component for driving the moving plate 8 to move horizontally is connected to the side of the moving plate 8 away from the limiting rod 4. The lower side of the first filler barrel 3 is detachably connected with a second filler barrel 9. By setting the first filler barrel 3 and the second filler barrel 9, the defoaming effect is further improved. A connection component for facilitating the installation and disassembly between the first filler barrel 3 and the second filler barrel 9 is arranged between the top of the second filler barrel 9 and the top of the first filler barrel 3. By setting the connection component, the installation and disassembly efficiency of the first filler barrel 3 and the second filler barrel 9 is improved. The connection component includes a connection block 10. One side of the connection block 10 is fixedly connected with the outer circumferential surface at the bottom of the first filler barrel 3. The other side of the connection block 10 is fixedly connected with a limiting block 11. A sliding rod 12 is slidably sleeved on the top of the limiting block 11. 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 with the top of the clamping rods 13. A connection column 14 is arranged between the two clamping rods 13. One end of the connection column 14 is fixedly connected with the inner wall at the top of the second filler barrel 9, so as to limit the connection column 14 through the clamping rods 13 and thus fix and limit the second filler barrel 9. A pressing ring 15 that can slide up and down is arranged on the top of the sliding rod 12. The pressing ring 15 is slidably installed on the outer circumferential surface at the bottom of the first filler barrel 3. One side of the upper surface of the pressing ring 15 is connected with the driving component.First, fill the fillers with a spiral structure inside the first filler bucket 3 and the second filler bucket 9. Pass the top end of the limiting rod 4 of the first filler bucket 3 through and sleeve it from the lower surface of the bucket lid 2, so that the limiting rod 4 is between the two clamping blocks 5. At this time, the first filler bucket 3 is below the bucket lid 2. At the same time, place the second filler bucket 9 at the bottom of the first filler bucket 3, and the connecting column 14 is between the two clamping rods 13. At this time, through the drive of the drive assembly, the moving plate 8 moves away from the limiting rod 4. Thus, under the rotational connection between the moving plate 8 and the clamping plate 6 and the rotational connection between the clamping plate 6 and the 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, and then the first filler bucket 3 is limited and fixed. While the drive assembly is running, it will drive the pressure ring 15 to slide down along the outer wall of the first filler bucket 3. The pressure ring 15 will gradually contact the slide rod 12 and press down the top of the slide rod 12. 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 limit block 11, the two clamping rods 13 will move towards each other, and then the clamping rod 13 will clamp and fix the connecting column 14, and finally the second filler bucket 9 is limited and fixed. Then, place the first filler bucket 3 and the second filler bucket 9 into the degassing bucket 1, and the bucket lid 2 contacts the top of the degassing bucket 1. Finally, through the sealing assembly, seal the degassing bucket 1 and the bucket lid 2. When in use, the adhesive liquid can be passed into the degassing bucket 1. Through the spiral fillers inside the first filler bucket 3 and the second filler bucket 9, the disturbance and shearing effects are enhanced, and the bubble separation efficiency is improved. When it is necessary to clean the degassing bucket 1, the first filler bucket 3, and the second filler bucket 9, first release the sealing limit of the sealing assembly, and then the bucket lid 2 can be taken out first. Then, by controlling the drive assembly to move in the reverse direction, the two clamping blocks 5 and the two clamping rods 13 can move away from each other. Finally, the limit on the limiting rod 4 and the connecting column 14 is released, and then the degassing bucket 1, the first filler bucket 3, and the second filler bucket 9 can be separated from each other, which is convenient for subsequent cleaning, avoiding cleaning dead corners, and there is no need to disassemble the entire degassing bucket 1 or even perform destructive cutting, resulting in a sharp increase in the equipment maintenance cost and an extension of the shutdown maintenance period.
[0022] Embodiment 2: On the basis of embodiment 1, a mounting ring frame 16 is fixedly provided on the outer ring surface of the degassing barrel 1, and the mounting ring frame 16 is convenient for fixing the degassing barrel 1 to external equipment, a discharge pipe 17 is fixedly provided on the bottom of the degassing barrel 1, a feed pipe 18 is fixedly installed on one side of the top of the degassing barrel 1, a valve 19 is fixedly provided on the feed pipe 18, a one-way valve 20 is fixedly installed on the other side of the top of the degassing barrel 1, and the one-way valve 20 is used for exhausting the inside of the degassing barrel 1, and the sealing component includes a connecting ear 21, which is arranged in a ring about the outer ring surface of the degassing barrel 1 and is fixedly connected to the degassing barrel 1, the connecting ear 21 is rotatably connected to one end of the connecting plate 22 through a limit pin, and the other end of the connecting plate 22 is threadedly sleeved with a crimping column 23, and the bottom of the crimping column 23 is slidably plugged into the pressure hole opened on the upper surface of the barrel cover 2. When the degassing barrel 1 needs to be used, the degassing barrel 1 is fixed to the external equipment through the mounting ring frame 16 fixedly sleeved on the outer ring surface thereof, and the degassing material is discharged through the discharge pipe 17 connected to the bottom of the degassing barrel 1.

The installed valve 19 is convenient for docking with an external pipeline on the one hand, and convenient for controlling the flow rate of the material on the other hand. When the barrel cover 2 is connected to the top of the degassing barrel 1, the first filling barrel 3 and the second filling barrel 9 filled with spiral structure fillers are inside the degassing barrel 1. In order to increase the sealing of the connection, the connecting plate 22 can be rotated toward the barrel cover 2, and then the crimping column 23 with the internal thread sleeve of the connecting plate 22 can be twisted to make the crimping column 23 close to the top of the barrel cover 2. Slide in the pressure hole opened until the connecting column 23 cannot be twisted by pressing. At this time, the barrel cover 2 is tightly covered on the top of the degassing barrel 1. During the degassing process, the gas inside the degassing barrel 1 is discharged outward through the one-way valve 20 to avoid excessive internal pressure. At the same time, the one-way valve 20 is connected to the external condenser input end, the condenser output end is connected to the gas-liquid separator input end, and the gas-liquid separator output end is connected to the atmospheric ejector output end. After the waste gas and water vapor generated by degassing flow away from the top of the degassing barrel 1 through the sealed pipeline, they first enter the condenser and cool down by cold water to condense the harmful gas and water vapor in the degassing into liquid, and then enter the gas-liquid separator to separate the liquid and the remaining gas by gravity. Finally, the remaining waste gas is sucked in by the atmospheric ejector with the help of high-speed water flow negative pressure and mixed with air to be diluted to a safe concentration for discharge. The whole process is processed by condensation liquefaction, physical separation and dynamic dilution to ensure that the harmful gas is discharged in compliance with the standard and realize resource recovery at the same time.

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 bottom of the inserting rod 43 is slidably inserted into a slot opened on the upper surface of the barrel cover 2. The slot limits the inserting rod 43. The upper surface of the moving block 29 is fixedly connected with a pushing frame 30 to one side of the moving plate 8. The pushing frame 30 is slidably installed inside the fixing frame 7. The transmission gear 34 is fixedly sleeved on the first threaded rod 28. When the first packing barrel 3 needs to be installed, first, the top of the limiting rod 4 fixedly connected to its top penetrates through the barrel cover 2, so that the limiting rod 4 is located 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 limitation of the stabilizing rod 27, thereby driving the driving gear 33 to rotate. The driving gear 33 drives the driven gear 35 to rotate through the meshing transmission of the transmission gear 34. When the transmission gear 34 rotates, it will drive the first threaded rod 28 fixedly sleeved on it to rotate. Two sections of threads with opposite helix directions are provided on the first threaded rod 28. Thus, under the rotation of the first threaded rod 28, the two moving blocks 29 move. The moving block 29 and the slot of the inserting rod 43 are in sliding fit, and then the moving block 29 moves towards each other along the axis direction of the first threaded rod 28. The moving block 29 drives the pushing frame 30 fixedly connected to its upper side to move synchronously. One end of the pushing frame 30 is fixedly connected with the moving plate 8. Thus, the two moving plates 8 move towards each other, and the moving plate 8 moves in a direction away from the limiting rod 4. The moving plate 8 drives the connecting frame 26 to pull the clamping plate 6 to move through the rotational connection between the support frames 25 on its upper and lower sides and the connecting frame 26. One end of the clamping plate 6 is rotatably connected to the fixing rod 24 on the fixing frame 7, and the other end of the clamping plate 6 moves towards the direction close to the limiting rod 4, so that the two limiting rods 4 drive the clamping blocks 5 to clamp and fix the limiting rod 4, and then the first packing barrel 3 is fixedly limited, and the first packing barrel 3 is installed below the barrel cover 2. When the first packing barrel 3 needs to be disassembled,Just turn the handwheel 32 in the reverse direction. When the first packing bucket 3 is installed, the second packing bucket 9 is installed synchronously at the same time, realizing the synchronous installation and disassembly of the first packing bucket 3 and the second packing bucket 9, improving the maintenance efficiency, and further enhancing the subsequent defoaming efficiency.
[0024] Embodiment 4: On the basis of Embodiment 3, the driven gear 35 is fixedly sleeved on the top end of the rotating shaft 36, the bottom end of the rotating shaft 36 is rotatably sleeved in the bucket cover 2, and the bucket cover 2 limits the rotating shaft 36. A driving meshing wheel 37 is arranged below the driven gear 35. The driving meshing wheel 37 is meshed and driven with the driven meshing wheel 39 through a 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 a pressing ring 15. The second threaded rod 40 is rotatably sleeved in a limiting sleeve fixedly connected to the upper surface of the bucket cover 2. Both sides of the inner circumferential surface of the pressing ring 15 are slidably installed on the semi-cylinder 41. The semi-cylinder 41 is fixedly connected to the outer wall of the first packing bucket 3. The top of the clamping rod 13 is slidably connected to the bottom of the sliding rod 12 through an arc surface formed thereon and an inclined surface formed at the bottom of the sliding rod 12. The bottom of the clamping rod 13 is fixedly connected to the end of a return spring 42. The clamping rod 13 is rotatably connected to the limiting block 11 through a fixing pin. A plurality of through holes are formed at the bottoms of the first packing bucket 3 and the second packing bucket 9 to facilitate the flow of materials. When the second packing bucket 9 needs to be installed, the second packing bucket 9 is placed at the bottom of the first packing bucket 3 in advance, and the connecting column 14 is located between the two clamping rods 13. When the driving assembly operates, the driven gear 35 drives the driving meshing wheel 37 to rotate through the connection of the rotating shaft 36. The driving meshing wheel 37 drives the driven meshing wheel 39 to rotate under the meshing drive of the meshing belt 38. The driven meshing wheel 39 is fixedly sleeved on the top of the second threaded rod 40. The second threaded rod 40 is rotatably installed on the top of the bucket cover 2. The bottom of the second threaded rod 40 is threadedly connected to the pressing ring 15, so that the pressing ring 15 can be driven to move. The pressing ring 15 slides downward under the limitation of the semi-cylinder 41, and then the pressing ring 15 presses the sliding rod 12 to slide downward under the limitation of the limiting block 11. The sliding rod 12 is slidably connected to the top of the clamping rod 13 through the inclined surface at its bottom and the arc surface at the top of the clamping rod 13, so that the two clamping rods 13 move towards each other and compress the return spring 42 at the same time. Under the limitation of the fixing pin, the two clamping rods 13 move towards each other, limit and fix the connecting column 14. The connecting column 14 is fixedly connected to the inner wall of the second packing bucket 9, and finally the fixing of the second packing bucket 9 is completed. When the handwheel 32 rotates in the reverse direction, the sliding 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, facilitating the disassembly of the second packing bucket 9 and subsequent cleaning.
