Abstract
Description
Technical Field
[0001] This invention relates to the field of pulp processing technology, and in particular to a high-speed mixing device for bio-based papermaking additives. Background Technology
[0002] The high-speed mixing device for bio-based papermaking additives is a core specialized equipment for green papermaking transformation using biomass conversion materials. It is specifically designed for bio-based additives such as starch, cellulose, lignin, and chitosan, which are prone to agglomeration. It can automatically produce working solutions for papermaking additives and is a prerequisite for the large-scale application of bio-based additives to replace petroleum-based synthetic additives. At present, when using the high-speed mixing device for bio-based papermaking additives, if the pulp concentration is too high or the pulping time is insufficient during pulping, a large number of incompletely dispersed dry pulp nuclei will be generated. In particular, high wet strength pulp and unbleached softwood pulp have strong hydrogen bonding between fibers, which easily form internally compact pulp clumps. These clumps will form raised hard lumps, spots, and translucent points on the paper surface, seriously affecting the appearance quality of the paper. Summary of the Invention
[0003] To overcome the shortcomings of the prior art, the present invention provides a high-speed mixing device for bio-based papermaking additives.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-speed mixing device for bio-based papermaking additives, comprising a processing cylinder, a processing shell fixedly connected to the top of the processing cylinder, a top plate fixedly connected to the top of the processing shell, a starting component for processing raw materials for high-speed mixing of bio-based papermaking additives inside the processing cylinder, the starting component comprising a sliding column and a pressure stirring frame, the cooperation of the sliding column and the pressure stirring frame providing power for high-speed mixing of bio-based papermaking additives, a support frame comprising a support frame disposed at the bottom of two support plates, two support columns fixedly connected to the bottom of the support frame, and a placement column fixedly connected between the two support columns. An extension bar, L-shaped, is fixedly connected to the outer side of the device. A servo motor is fixedly connected to the bottom of the extension bar. A second housing is fixedly connected to the outer side of the servo motor, and the servo motor is housed inside the second housing. A bearing plate is fixedly connected to the bottom of the extension bar, and a bearing is mounted on the bearing plate. A transmission column is fixedly connected to the inner ring of the bearing on the bearing plate, and the output shaft of the servo motor is fixedly connected to the transmission column. A sliding block is fixedly connected to the end of the transmission column away from the servo motor. The sliding column is movably connected to the sliding block. A track plate is inserted into the top of the sliding column, and a stirring plate is fixedly connected to the bottom of the sliding column. A first spring is sleeved on the outer side of the sliding column, and both ends of the first spring are respectively connected to the sliding block. The starting assembly, which is fixedly connected to the track plate, also includes a support block. The support block is movably connected to the outside of the placement column. A limit post is fixedly connected to the bottom of the support block, and a blocking plate is fixedly connected to the bottom of the limit post. A lifting block is movably connected to the outside of the limit post, and a positioning bolt is fixedly connected to the outside of the lifting block. The outside of the positioning bolt is movably connected to the track plate. A mixing frame is fixedly connected to the outside of the lifting block, and the mixing frame has two elongated holes for promoting high-speed mixing of raw materials. The interior of the processing cylinder contains a purification component that works in conjunction with the processing assembly. The purification component includes a filter plate and a moving frame. Through the cooperation of the filter plate and the moving frame, the pulp in the mixture of pulp and bio-based additives can be purified. The material is subjected to extrusion and grinding. The impurity removal component has a movable shell, which is fixedly connected to one end of the support block. A placement frame is fixedly connected to the bottom of the support frame. The filter sheet is fixedly connected to the placement frame, which is semi-open. One end of the placement frame is fixedly connected to two support columns. Several connecting columns are inserted into the inside of the movable shell. A connecting plate is fixedly connected to the top of each connecting column. Several second springs are provided inside the movable shell. The two ends of each second spring are fixedly connected to the corresponding connecting plate and the inner wall of the movable shell, respectively. The bottom of each connecting column is fixedly connected to the movable frame. The filter sheet has several small round holes for processing raw material clumps.
[0005] Through the above technical solution, when it is necessary to mix the raw materials, the servo motor is started, which drives the transmission column to rotate. As the transmission column rotates, it drives the sliding block to rotate. When the sliding block rotates to a vertical position, the first spring is compressed due to the obstruction of the sliding block and the track plate. When the transmission column begins to rotate clockwise, the sliding block drives the sliding column to rotate, which in turn drives the track plate to rotate. The track plate then rotates along the positioning bolt. As the track plate rotates, the distance between the track plate and the sliding block begins to widen, causing the compressed first spring to gradually rebound. This rebound pushes the track plate and the sliding column to move, and the tilt angle of the track plate causes the lifting block on the positioning bolt to move. The lifting block, in turn, drives the limiting post to move, and the limiting post, in turn, drives the bearing block to translate along the placement column. When the bearing block moves to the farthest end of the placement column, the compressed first spring is released, and the track plate, through the positioning bolt, pushes the lifting block to slide down along the outside of the limiting post. As the lifting block moves, it drives the stirring frame to rotate and squeeze the raw materials inside the processing cylinder. When the track plate rotates to the position at the bottom of the servo motor and continues to rotate, the distance between the track plate and the sliding block begins to decrease, and the first spring is compressed. When the track plate begins to rotate and rise, the compressed first spring begins to rebound. Then, the lifting block drives the bearing block to move along the placement column to the other farthest end through the limiting column. Then, as the track plate continues to rotate and rise, it drives the first spring to continue to compress and return to its initial state. During the continuous rotation of the sliding column, it drives the stirring plate to rotate and mix the raw materials on the inner wall of the processing cylinder. When the raw materials processed by the filter plate fall to the top of the filter plate, the lifting block moves back and forth along the placement column, and then the lifting block drives the moving shell to move. When the moving shell moves, it drives the moving frame to move through the connecting column. When the moving frame moves, it squeezes the raw materials on the top of the filter plate along its small round holes and drops them. During the movement of the moving frame, the slurry formed in the raw materials is squeezed and ground up by the round holes of the filter plate.
[0006] In a preferred embodiment of the present invention, two support plates are fixedly connected inside the processing shell. A processing component for cooperating with the starting assembly is located between the two support plates. The processing component contains a threaded block and a compaction cylinder. The cooperation of the threaded block and the compaction cylinder allows for the removal of impurities from the bio-based papermaking additives. A filter plate is located inside the processing component and is fixedly connected to the top of the support frame. The filter plate has several large mesh holes for blocking fibers. A support platform is fixedly connected to each end of the support frame. A first housing is fixedly connected to the outer side of one of the support platforms. A stepper motor is located inside the first housing. Each support platform has a bearing, and the inner ring of each bearing is fixedly connected to a double-threaded post. The output shaft of the stepper motor is fixedly connected to the double-threaded post. There are two threaded blocks, threadedly connected to the positive and negative thread sections of the double-threaded post, respectively. A support strip is fixedly connected to each end of each threaded block. Each support strip is L-shaped, and each support plate has an L-groove for placing the support strip. Each support bar is movably connected to the L-groove of the corresponding support plate. A movable column is fixedly connected to the top of each support bar. The processing assembly has two racks, each fixedly connected to the top of the corresponding support plate. A movable column is movably connected between every two corresponding movable columns. A gear is fixedly connected to both ends of each movable column, and each gear meshes with the corresponding rack. A compaction cylinder is fixedly connected to the outside of each movable column. An actuation frame is fixedly connected to the top of the two corresponding movable columns. A scraper is fixedly connected to the actuation frame. A discharge pipe is fixedly connected to the bottom of the processing cylinder. Two feed cylinders are fixedly connected to the top of the top plate. A vibrating shell is fixedly connected inside the top plate. Several actuation blocks are inserted into the vibrating shell. A support ring is fixedly connected to the outside of each actuation block. Each extension bar is C-shaped. Each extension bar has a semi-circular chamfer at the top. Each actuation block has a semi-arc at the bottom. When the extension bar moves to the position of the corresponding actuation block, the extension bar fits into the actuation block.
[0007] Through the above technical solution, when high-speed mixing of bio-based papermaking additives is required, the raw materials and chemical additives are poured in separately along two feed cylinders. The raw materials and chemical additives then fall to the top of the filter plate. Immediately, a stepper motor is activated, driving a double-headed threaded column to rotate. As the double-headed threaded column rotates, it causes two threaded blocks to contract and move towards the center of the filter plate. The moving threaded blocks move the corresponding support strips along the support plate, which in turn moves the moving column. The moving column, in turn, moves the movable column, which in turn moves the gear. Because the gear meshes with a rack, the gear rotates as it moves along the rack, driven by the rack's influence. This rotation of the gear drives the movable column to rotate, which in turn rotates the compaction cylinder. The compaction cylinder, in turn, moves and crushes the raw materials accumulated on top of the filter plate. In the raw material crushed by the compaction cylinder, evenly dispersed fine fibers can fall through the large mesh of the filter plate to the next process. Unbroken large-sized dry pulp nuclei and fiber clumps are intercepted on the top of the filter plate and continue to be crushed. When the compaction cylinder rotates, it is affected by the scraper, and the raw material attached to the compaction cylinder is scraped off by the scraper. When the trigger frame moves to the position of the trigger block, the trigger frame pushes the corresponding trigger block to move towards the inside of the vibrating shell. When the trigger block moves, it drives the bearing ring to move. When the trigger frame leaves the position of the corresponding trigger block, the trigger block falls vertically under the influence of gravity. Then, several bearing rings hit the inner wall of the vibrating shell to produce intermittent vibration. When the two compaction cylinders move to the close position, the stepper motor is started to make the double-headed threaded column rotate in the opposite direction. Then, the two threaded blocks drive the corresponding compaction cylinder to reset and move. The raw material on the top of the filter plate falls to the top of the filter plate under the repeated crushing of the compaction cylinder.
[0008] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention, through the coordinated use of the starting component, the processing component, and the impurity removal component, utilizes a double-compression cylinder composite rolling structure with synchronously driven positive and negative thread sections of a double-headed threaded column, combined with a graded interception and pre-screening mechanism of the filter plate. This allows for the step-by-step crushing and dispersion of dry pulp nuclei and large fiber clusters formed from high-wet-strength pulp and unbleached softwood pulp, which have tightly cross-linked internal fibers and high hardness. This improves the appearance quality and printability of the product.
[0009] 2. The present invention utilizes the reciprocating compression between the moving frame and the filter with small round holes in the impurity removal component, and the adaptive clamping force provided by the second spring, to thoroughly crush the small pulp clumps that have passed through the first process into single fibers, while ensuring that the pulp passes smoothly through the filter holes, thus avoiding the problems of pulp clumps clogging the flow channel and subsequent adsorption aids forming composite agglomerates.
[0010] 3. This invention achieves three-dimensional composite motion of horizontal reciprocating translation, vertical lifting and rotating by a pressure stirring frame driven by a trajectory plate in the start-up component. This creates a strong shearing and extrusion mixing effect on the raw materials in the processing cylinder, which can quickly break up the hydrogen-bonded aggregates of bio-based polymers, avoid the formation of fish-eye gels, and improve the dispersion uniformity and mixing efficiency of the additives.
[0011] 4. The present invention uses a stirring plate structure that rotates at the bottom of the sliding column to continuously scrape the inner wall of the treatment cylinder during the mixing process, preventing the raw materials from depositing on the cylinder wall and forming secondary pulp clumps. This ensures the consistency of pulp concentration and composition throughout the cylinder and avoids paper performance fluctuations caused by uneven mixing.
[0012] 5. This invention, through the coordinated use of the starting component, processing component, and impurity removal component, and the self-cleaning design of the touch frame and scraper above the compaction cylinder, can scrape off the raw material fibers adhering to the surface of the compaction cylinder in real time, preventing material accumulation from affecting the compaction effect. At the same time, the intermittent vibration generated by the collision between the touch block driven by the scraper and the bearing ring can effectively prevent the filter plate mesh from clogging, ensuring the stability of continuous operation.
[0013] 6. This invention constructs a two-stage graded impurity removal system by using the start-up component, processing component and impurity removal component in combination. This system consists of large-mesh pre-filtration, compaction cylinder coarse crushing and small round hole fine grinding. It can specifically treat slurry clumps and fiber aggregates of different particle sizes. The impurity removal efficiency is significantly higher than that of a single filtration device. At the same time, it avoids the wear of subsequent mixing components by large particles of impurities and extends the service life of the equipment. Attached Figure Description

[0017] Example: Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a high-speed mixing device for bio-based papermaking additives includes a processing cylinder 1. A processing shell 2 is fixedly connected to the top of the processing cylinder 1, and a top plate 3 is fixedly connected to the top of the processing shell 2. The processing cylinder 1 contains a starting assembly for processing the raw materials for high-speed mixing of bio-based papermaking additives. The starting assembly includes a sliding column 32 and a pressure stirring frame 41. The cooperation of the sliding column 32 and the pressure stirring frame 41 provides power for high-speed mixing of bio-based papermaking additives. The starting assembly also includes a support frame 11, which is located at the bottom of two support plates 6. Two support columns 21 are fixedly connected to the bottom of the support frame 11, and a placement column 22 is fixedly connected between the two support columns 21. An extension strip 25 is fixedly connected to the outer side of the support frame 11. The extension strip 25 is L-shaped. The extension bar 25 has a servo motor 28 fixedly connected to its bottom. A second housing 26 is fixedly connected to the outside of the servo motor 28, and the servo motor 28 is housed inside the second housing 26. A bearing plate 27 is fixedly connected to the bottom of the extension bar 25, and a bearing is mounted on the bearing plate 27. A transmission column 29 is fixedly connected to the inner ring of the bearing on the bearing plate 27, and the output shaft of the servo motor 28 is fixedly connected to the transmission column 29. A sliding block 31 is fixedly connected to the end of the transmission column 29 away from the servo motor 28. A sliding column 32 is movably connected to the sliding block 31. A track plate 40 is inserted into the top of the sliding column 32, and a stirring plate 39 is fixedly connected to the bottom of the sliding column 32. A first spring 33 is sleeved on the outside of the sliding column 32, and the two ends of the first spring 33 are respectively connected to the sliding block 31. Block 31 and track plate 40 are fixedly connected. The starting assembly also includes a support block 30, which is movably connected to the outside of the placement column 22. A limit post 37 is fixedly connected to the bottom of the support block 30, and a blocking plate 38 is fixedly connected to the bottom of the limit post 37. A lifting block 35 is movably connected to the outside of the limit post 37, and a positioning bolt 34 is fixedly connected to the outside of the lifting block 35. The outside of the positioning bolt 34 is movably connected to the track plate 40. A stirring frame 41 is fixedly connected to the outside of the lifting block 35, and the stirring frame 41 is provided with two elongated holes for promoting high-speed mixing of raw materials. The inside of the processing cylinder 1 is provided with a purification component for cooperating with the processing assembly. The purification component is provided with a filter plate 24 and a moving frame 43. Through the cooperation of the filter plate 24 and the moving frame 43, the impurity can be removed from the filter plate 24 and the moving frame 43. The pulp lumps in the pulp and bio-based additive mixture are extruded and ground. A movable shell 42 is provided within the impurity removal component, fixedly connected to one end of the support block 30. A placement frame 23 is fixedly connected to the bottom of the support frame 11, and a filter sheet 24 is fixedly connected within the placement frame 23, which is semi-open. One end of the placement frame 23 is fixedly connected to two support columns 21. Several connecting columns 44 are inserted inside the movable shell 42, and a connecting plate 46 is fixedly connected to the top of each connecting column 44. Several second springs 45 are provided inside the movable shell 42, with both ends of each second spring 45 fixedly connected to the corresponding connecting plate 46 and the inner wall of the movable shell 42, respectively. The bottom of each connecting column 44 is fixedly connected to the movable frame 43.The filter plate 24 is provided with a plurality of small round holes for processing raw material clumps; like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, when the raw materials need to be mixed, the servo motor 28 is started. The servo motor 28 drives the transmission column 29 to rotate. When the transmission column 29 rotates, it drives the sliding block 31 to rotate. When the sliding block 31 rotates to the vertical position, the first spring 33 is compressed under the obstruction of the sliding block 31 and the track plate 40. When the transmission column 29 starts to rotate clockwise, the sliding block 31 drives the sliding column 32 to rotate. When the sliding column 32 rotates, it drives the track plate 40 to rotate. Then the track plate 40 rotates along the positioning pin 34. When the track plate 40 rotates, it causes the track plate 40 and the sliding block to rotate. The gap between points 31 begins to widen, causing the compressed first spring 33 to gradually rebound. As the first spring 33 rebounds, it pushes the track plate 40 and the sliding post 32 to move. The tilt angle of the track plate 40 causes the lifting block 35 on the positioning bolt 34 to move. The lifting block 35, in turn, moves the limiting post 37. The limiting post 37, in turn, moves the bearing block 30 along the placement post 22. When the bearing block 30 reaches the farthest end of the placement post 22, the compressed first spring 33 rebounds and releases. The track plate 40, through the positioning bolt 34, pushes the lifting block 35 along the outside of the limiting post 37. As the sliding block 35 moves downwards, it drives the pressure and mixing frame 41 to rotate and squeeze the raw materials inside the processing cylinder 1. When the track plate 40 rotates to the position at the bottom of the servo motor 28 and continues to rotate, the distance between the track plate 40 and the sliding block 31 begins to decrease, and the first spring 33 is compressed. When the track plate 40 begins to rotate and rise, the compressed first spring 33 begins to rebound. Then, the lifting block 35 drives the bearing block 30 to move along the placement column 22 to the other farthest end through the limiting column 37. Then, as the track plate 40 continues to rotate and rise, it drives the first spring 33 to continue to compress and recover. Initially, as the sliding column 32 rotates continuously, it drives the stirring plate 39 to rotate and mix the raw material on the inner wall of the processing cylinder 1. When the raw material processed by the filter plate 20 falls to the top of the filter plate 24, the lifting block 35 moves back and forth along the placement column 22, thereby driving the moving shell 42 to move. When the moving shell 42 moves, it drives the moving frame 43 to move through the connecting column 44. When the moving frame 43 moves, it squeezes the raw material on the top of the filter plate 24 through its small round hole and drops it. During the movement of the moving frame 43, the slurry formed in the raw material is squeezed and ground by the round hole of the filter plate 24.
[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, two support plates 6 are fixedly connected inside the processing shell 2. A processing component for cooperating with the starting component is provided between the two support plates 6. The processing component contains a threaded block 12 and a compaction cylinder 19. The cooperation of the threaded block 12 and the compaction cylinder 19 can process impurities in the bio-based papermaking additives. A filter plate 20 is provided inside the processing component. The filter plate 20 is fixedly connected to the top of the support frame 11. The filter plate 20 has several large mesh holes for blocking fibers. A support platform 7 is fixedly connected to each end of the support frame 11. The outer side of one of the support platforms 7 is fixed. A first housing 8 is connected to the first housing 8, and a stepper motor 9 is installed inside the first housing 8. Each support platform 7 is equipped with a bearing, and the inner ring of the bearing of each support platform 7 is fixedly connected to a double-threaded post 10. The output shaft of the stepper motor 9 is fixedly connected to the double-threaded post 10. There are two threaded blocks 12, which are threadedly connected to the positive and negative thread sections of the double-threaded post 10, respectively. Each end of each threaded block 12 is fixedly connected to a support bar 13. Each support bar 13 is L-shaped, and each support plate 6 is provided with an L-groove for placing the support bar 13. Each support bar 13 is movably connected to the opposite end of the support plate 6. In the L-groove of the bearing plate 6, a movable column 14 is fixedly connected to the top of each bearing bar 13. The processing assembly contains two racks 49, each fixedly connected to the top of its corresponding bearing plate 6. A movable column 15 is movably connected between every two corresponding movable columns 14. A gear 16 is fixedly connected to both ends of each movable column 15, and each gear 16 meshes with its corresponding rack 49. A compaction cylinder 19 is fixedly connected to the outer side of each movable column 15. An actuating frame 18 is fixedly connected to the top of the two corresponding movable columns 14. A scraper 17 is fixedly connected to the top, a discharge pipe 5 is fixedly connected to the bottom of the processing cylinder 1, two feed cylinders 4 are fixedly connected to the top of the top plate 3, a vibrating shell 47 is fixedly connected inside the top plate 3, several actuating blocks 48 are inserted into the vibrating shell 47, a bearing ring 36 is fixedly connected to the outside of each actuating block 48, each extension bar 25 is C-shaped, the top of each extension bar 25 is provided with a semi-circular chamfer, and the bottom of each actuating block 48 is semi-arc. When the extension bar 25 moves to the position of the corresponding actuating block 48, the extension bar 25 and the actuating block 48 are in contact. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, when high-speed mixing of bio-based papermaking additives is required, the raw materials and chemical additives are poured in separately along the two feed cylinders 4, and then the raw materials and chemical additives fall to the top of the filter plate 20. Immediately, the stepper motor 9 is started, driving the double-headed threaded column 10 to rotate. As the double-headed threaded column 10 rotates, it causes the two threaded blocks 12 to retract and move towards the center of the filter plate 20. As the threaded blocks 12 move, they cause the corresponding support strips 13 to move along the support plate 6. As the support strips 13 move, they... The movable column 14 moves, which in turn moves the movable column 15. The movable column 15, in turn, moves the gear 16. Because the gear 16 meshes with the rack 49, it rotates along the rack 49. This rotation of the gear 16 causes the movable column 15 to rotate, which in turn causes the compaction cylinder 19 to rotate. As the compaction cylinder 19 rotates, it moves and crushes the raw material accumulated on top of the filter plate 20. In the crushed raw material 19, evenly dispersed fine fibers can fall through the large mesh of the filter plate 20 to the next process, while large, unbroken dry pulp nuclei and fiber clumps are intercepted at the top of the filter plate 20 and continue to be crushed. As the compaction cylinder 19 rotates, it is affected by the scraper 17, causing the raw material adhering to the compaction cylinder 19 to be scraped off. When the trigger frame 18 moves to the corresponding position of the trigger block 48, the trigger frame 18 pushes the corresponding trigger block 48 towards the inside of the vibrating shell 47. The trigger block 48 moves... The bearing ring 36 moves when the trigger frame 18 leaves the position of the corresponding trigger block 48. The trigger block 48 falls vertically due to gravity. Then, several bearing rings 36 hit the inner wall of the vibrating shell 47 and produce intermittent vibration. When the two compaction cylinders 19 move to the fit position, the stepper motor 9 is started to make the double-headed threaded column 10 rotate in the opposite direction. Then, the two threaded blocks 12 drive the corresponding compaction cylinders 19 to reset and move. The raw material on the top of the filter plate 20 falls to the top of the filter disc 24 under the repeated crushing of the compaction cylinders 19.
[0019] Working principle: Step 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, when high-speed mixing of bio-based papermaking additives is required, the raw materials and chemical additives are poured in separately along the two feed cylinders 4, and then the raw materials and chemical additives fall to the top of the filter plate 20. Immediately, the stepper motor 9 is started, driving the double-headed threaded column 10 to rotate. As the double-headed threaded column 10 rotates, it causes the two threaded blocks 12 to retract and move towards the center of the filter plate 20. As the threaded blocks 12 move, they cause the corresponding support strips 13 to move along the support plate 6. As the support strips 13 move, they... The movable column 14 moves, which in turn moves the movable column 15. The movable column 15, in turn, moves the gear 16. Because the gear 16 meshes with the rack 49, it rotates along the rack 49. This rotation of the gear 16 causes the movable column 15 to rotate, which in turn causes the compaction cylinder 19 to rotate. As the compaction cylinder 19 rotates, it moves and crushes the raw material accumulated on top of the filter plate 20. In the crushed raw material 19, evenly dispersed fine fibers can fall through the large mesh of the filter plate 20 to the next process, while large, unbroken dry pulp nuclei and fiber clumps are intercepted at the top of the filter plate 20 and continue to be crushed. As the compaction cylinder 19 rotates, it is affected by the scraper 17, causing the raw material adhering to the compaction cylinder 19 to be scraped off. When the trigger frame 18 moves to the corresponding position of the trigger block 48, the trigger frame 18 pushes the corresponding trigger block 48 towards the inside of the vibrating shell 47. The trigger block 48 moves... The bearing ring 36 moves when the trigger frame 18 leaves the position of the corresponding trigger block 48. The trigger block 48 falls vertically due to gravity. Then, several bearing rings 36 hit the inner wall of the vibrating shell 47 and produce intermittent vibration. When the two compaction cylinders 19 move to the fit position, the stepper motor 9 is started to make the double-headed threaded column 10 rotate in the opposite direction. Then, the two threaded blocks 12 drive the corresponding compaction cylinders 19 to reset and move. The raw material on the top of the filter plate 20 falls to the top of the filter sheet 24 under the repeated crushing of the compaction cylinders 19. Step 2, as follows Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, when the raw materials need to be mixed, the servo motor 28 is started. The servo motor 28 drives the transmission column 29 to rotate. When the transmission column 29 rotates, it drives the sliding block 31 to rotate. When the sliding block 31 rotates to a vertical position, the first spring 33 is compressed under the obstruction of the sliding block 31 and the track plate 40. When the transmission column 29 starts to rotate clockwise, the sliding block 31 drives the sliding column 32 to rotate. When the sliding column 32 rotates, it drives the track plate 40 to rotate. Then, the track plate 40 rotates along the positioning bolt 34. When the track plate 40 rotates, it makes the distance between the track plate 40 and the sliding block 31... As the distance begins to expand, the compressed first spring 33 gradually rebounds. During this rebound, the first spring 33 pushes the track plate 40 and the sliding post 32 to move. The tilt angle of the track plate 40 causes the lifting block 35 on the positioning bolt 34 to move. The lifting block 35, in turn, moves the limiting post 37. The limiting post 37, in turn, moves the bearing block 30 along the placement post 22. When the bearing block 30 reaches the farthest end of the placement post 22, the compressed first spring 33 has fully rebounded and released. The track plate 40, through the positioning bolt 34, pushes the lifting block 35 to slide and descend along the outside of the limiting post 37, and then rises... As the lifting block 35 moves, it drives the pressure and stirring frame 41 to rotate and squeeze the raw materials inside the processing cylinder 1. When the track plate 40 rotates to the position at the bottom of the servo motor 28 and continues to rotate, the distance between the track plate 40 and the sliding block 31 begins to decrease, and the first spring 33 is compressed. When the track plate 40 begins to rotate and rise, the compressed first spring 33 begins to rebound. Then, the lifting block 35 drives the bearing block 30 to move along the placement column 22 to the other farthest end through the limiting column 37. Then, as the track plate 40 continues to rotate and rise, it drives the first spring 33 to continue to compress and return to its initial state. The sliding column 32 rotates continuously. During the rotation, the stirring plate 39 drives the raw material on the inner wall of the processing cylinder 1 to rotate and mix. When the raw material processed by the filter plate 20 falls to the top of the filter plate 24, the lifting block 35 moves back and forth along the placement column 22, thereby driving the moving shell 42 to move. When the moving shell 42 moves, it drives the moving frame 43 to move through the connecting column 44. When the moving frame 43 moves, it squeezes the raw material on the top of the filter plate 24 through its small round hole and drops it. During the movement of the moving frame 43, the slurry formed in the raw material is squeezed and ground by the round hole of the filter plate 24, and the raw material that has been mixed at high speed is discharged from the discharge pipe 5.
