Technical Field
[0001] This invention relates to the field of popping bead drop production technology, specifically to a dual-cavity linkage production and processing equipment for popping bead drops. Background Technology
[0002] As a preparation with specific sustained-release and immediate-release functions, the production process of popping droplets has extremely stringent requirements for drying technology. On the one hand, it is necessary to ensure drying efficiency to meet the needs of industrial production, and on the other hand, it is necessary to ensure drying uniformity to avoid local over-drying and cracking or under-drying and sticking. At the same time, it is also necessary to protect the integrity of the capsule structure of the popping droplets to prevent damage caused by collision or compression.
[0003] Existing equipment for producing and processing popping beads has several technical problems in the drying process. These problems are as follows: Existing popping bead drying equipment generally adopts a single-chamber drying structure. Its core defect is that the contradiction between efficient drying and uniform drying cannot be reconciled, and the material is easily damaged during the drying process. Specifically, in pursuit of efficiency, existing equipment often adopts strong agitation and high-temperature rapid drying modes. However, under this mode, materials tend to accumulate in localized areas of the chamber, and hot air cannot penetrate the accumulated layer, resulting in an over-dry outer layer and an under-dry inner layer, leading to extremely poor drying uniformity. In addition, when the chamber is turned over or materials are conveyed, the materials tend to move in a cascading manner, which can easily cause collisions and compression, leading to damage to the shell. At the same time, existing devices lack an effective dispersion mechanism, and materials are prone to sticking and clumping due to differences in surface moisture during the drying process. Based on this, the present invention provides a dual-cavity linkage production and processing equipment for popping droplets to solve the problems mentioned in the background art. Summary of the Invention
[0004] This invention addresses the technical problems existing in the prior art by providing a dual-chamber linkage production and processing equipment for popping droplets. This solves the problem that existing popping droplet drying equipment generally adopts a single-chamber drying structure, which cannot reconcile the contradiction between efficient drying and uniform drying.
[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A dual-cavity linkage production and processing equipment for popping droplets includes a frame on which an independently rotating tilting cylinder and a tube shaft are mounted. The two ends of the tilting cylinder are rotatably connected to a drying tank and a quick-drying tank, respectively. Both the drying tank and the quick-drying tank are driven by the tube shaft. The drying tank has a drying chamber, and the quick-drying tank has a quick-drying chamber. A reciprocating frame is slidably connected to the tilting cylinder. A reciprocating drive mechanism is mounted on the tube shaft to drive the reciprocating frame to cyclically change amplitude and reciprocate. A stirring shaft linked to the quick-drying tank and a main shaft linked to the drying tank are rotatably connected to the reciprocating frame. Stirring rods are mounted on the stirring shaft at positions corresponding to the inner side of the quick-drying tank.

The valve shaft rotates synchronously. A moving valve disc is installed at the bottom of the valve shaft, and a disturbance rod is arrayed on its upper part. Valve holes are arrayed on both the moving valve disc and the fixed valve seat. The axis of the valve holes is parallel to the axis of the tilting cylinder. A dispersing cylinder and a return cylinder are fixedly connected on the drying tank. A return pipe and a feeding branch pipe are connected between the dispersing cylinder and the return cylinder, respectively. A dispersing shaft coaxial with the dispersing cylinder and a material shaft coaxial with the return cylinder are rotatably connected on the reciprocating frame. A first synchronous belt is driven and connected to the main shaft. The dispersing shaft and the material shaft are both driven and connected to the first synchronous belt.

A third synchronous belt is drivingly connected between the top shaft and the stirring shaft, and a fourth synchronous belt is drivingly connected between the bottom shaft and the main shaft.
[0010] As a preferred technical solution of the present invention, a hexagonal segment is fixedly provided at the bottom of the stirring shaft, and a hexagonal hole with open ends and slidably connected to the hexagonal segment is provided inside the valve shaft. The cross-sectional shape of the hexagonal segment and the hexagonal hole are both regular hexagonal.
[0011] As a preferred technical solution of the present invention, the reciprocating drive mechanism includes a drive wheel fixedly mounted on a tube shaft. Along the circumferential direction, the drive wheel is alternately provided with three sector tooth segments and three toothless arc surfaces. A toothed plate is mounted on the side of the reciprocating frame. The three sector tooth segments alternately mesh with the toothed plate, and the transmission stroke of the three sector tooth segments to the toothed plate is different. A guide frame is fixedly mounted on the tilting cylinder. A guide groove that is slidably connected to the guide frame is opened on the reciprocating frame. A first spring is mounted on the tilting cylinder. The other end of the first spring is fixedly connected to the reciprocating frame. A second spring is connected between the reciprocating frame and the quick-drying can.
[0012] As a preferred technical solution of the present invention, the heating system includes a hot air blower installed at the bottom of the frame. The air outlet of the hot air blower is connected to a hot air pipe. The air outlet of the hot air pipe is rotatably connected to a diverter ring. The diverter ring is fixedly connected to a rotating shaft at an adjacent position. Two air supply ring pipes are fixedly connected to the diverter ring. The two air supply ring pipes are rotatably connected to a drying tank and a quick-drying tank, respectively. An air guide chamber is provided inside the quick-drying tank. Ventilation holes communicating with the air supply ring pipes are arrayed on the outer wall of the air guide chamber and on the drying tank. Hot spray holes communicating with the air guide chamber are arrayed on the inner wall of the quick-drying tank.
[0013] As a preferred technical solution of the present invention, a temperature and humidity probe and a ventilation valve are installed on the rotating cylinder, and the data terminal of the temperature and humidity probe and the electrical control terminal of the ventilation valve are both connected to the central control unit.
[0014] As a preferred embodiment of the present invention, the fixed valve seat is disposed between the quick-drying chamber and the fine-drying chamber.
[0015] The beneficial effects of this invention are: 1. Traditional popping bead drying equipment generally adopts single-chamber drying, which has the core technical problems of low drying efficiency and local over-drying or under-drying of materials. In addition, the material is prone to spillage and accumulation during material switching, damaging the particle structure. This invention achieves synergistic complementarity between the fast drying process and the fine drying process through a dual-chamber linkage design. The periodic 180° rotation of the rotating drum and the tube shaft driven fine drying tank and fast drying tank form a precise linkage, allowing the material to alternately circulate into the fast drying chamber and the fine drying chamber. The dual-chamber function can be seamlessly switched. At the same time, the fixed valve seat, moving valve disc and array valve holes between the fast drying chamber and the fine drying chamber constitute a fractional drying mechanism. With the synchronous rotation of the valve shaft and the stirring shaft, the disturbance rod effectively prevents material blockage and allows the material to be slowly and evenly distributed to the target chamber, avoiding the accumulation problem caused by material spillage in traditional equipment. This multi-component linkage mode of rotating drum, valve shaft and stirring shaft improves drying efficiency compared with the existing single drying chamber design, achieving a dual breakthrough in efficiency and uniformity, and protecting the structural integrity of popping bead drops throughout the process.
[0016] 2. Existing drying equipment mostly uses fixed-stroke stirring, which easily leads to material adhesion and clumping, and uneven force on particles. This invention constructs a synergistic mechanism of cyclic dispersion and variable-amplitude reciprocating stirring. The reciprocating drive mechanism driven by the tube shaft drives the reciprocating frame to perform cyclic variable-amplitude reciprocating motion through three sector tooth sections with different numbers of teeth. With the high tooth ratio meshing design of the upper gear ring and the upper gear, and the lower gear ring and the lower gear, the stirring shaft and the main shaft maintain stable rotation during reciprocating movement, forming a linkage effect of variable-amplitude reciprocating and continuous stirring. At the same time, the main shaft links the dispersion shaft and the material shaft through the synchronous belt. The dispersion rod in the dispersion cylinder efficiently disperses the material. The spiral conveying blade in the return cylinder, together with the return pipe and the feeding branch pipe, forms a closed-loop circulation channel, so that the material circulates up and down between the dispersion cylinder and the return cylinder, realizing the integrated operation of circulation, dispersion and drying. This design breaks the limitations of traditional fixed-stroke stirring. The variable-amplitude motion ensures no dead corners in stirring, and the circulating flow ensures that each bursting droplet is evenly contacted by the hot airflow.
[0017] 3. In traditional drying equipment, the hot air delivery and chamber rotation are prone to interference, leading to interruptions in heat delivery and uneven temperature distribution within the chamber, affecting drying quality. This invention solves this problem through the linkage design of the heating system and moving parts. The hot air blower constructs a linkage heat delivery channel through hot air pipes, a distribution ring, and an air supply ring pipe. The distribution ring is fixedly connected to the rotation shaft, and the air supply ring pipe is rotatably connected to the finishing and quick-drying tanks, ensuring uninterrupted hot air delivery during the rotation of the rotating drum. This achieves dynamic coordination between the rotation movement and the heat delivery channel. At the same time, the air guide chamber in the quick-drying tank and the array of hot spray holes, as well as the array of ventilation holes in the finishing tank, form an all-round heat delivery structure. The hot airflow evenly covers the quick-drying chamber, the finishing chamber, the dispersion cylinder, and the return cylinder, avoiding local temperature differences. Compared with the fixed heat delivery design of the existing technology, this linkage mode of motion adaptation and uniform heat delivery improves the temperature uniformity within the chamber, achieving stable and uniform heat supply during the dynamic drying process and ensuring the continuity of the drying environment when switching between the two chambers.

[0020] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0021] The present invention provides the following preferred embodiments, such as Figure 1-10 As shown, the dual-cavity linkage production and processing equipment for popping droplets includes a frame 1, on which an independently rotating tilting cylinder 2 and a tube shaft 3 are mounted. The two ends of the rotating cylinder 2 are respectively connected to the drying tank 4 and the quick-drying tank 5. Both the drying tank 4 and the quick-drying tank 5 are driven by the tube shaft 3. The drying tank 4 is provided with a drying chamber, and the quick-drying tank 5 is provided with a quick-drying chamber. Both the drying tank 4 and the quick-drying tank 5 are made of 304 stainless steel. Two motors 23 are mounted on the frame 1. The output shafts of the two motors 23 are connected to a second synchronous belt. Two rotating shafts 24 are mounted on the rotating drum 2. One rotating shaft 24 is rotatably connected to the tube shaft 3 through a bearing. The other rotating shaft 24 and the tube shaft 3 are rotatably connected to the frame 1. The two second synchronous belts are respectively connected to the tube shaft 3 and one rotating shaft 24. The dual-motor 23 independent drive design allows for separate adjustment of the rotation speed of the tilting drum 2 and the tube shaft 3, adapting to the drying requirements of different materials and enhancing the versatility of the equipment. A drive bevel gear is installed on the tube shaft 3, and driven bevel gear rings are installed on both the fine drying tank 4 and the quick drying tank 5. Both driven bevel gear rings are connected to the drive bevel gear for transmission. Specifically, the quick-drying chamber uses the stirring principle to achieve rapid drying of the raw materials for the bursting droplets, while the fine-drying chamber uses the principles of circulation and reflux to achieve fine drying of the raw materials for the bursting droplets and ensure their uniformity of drying. In a preferred embodiment, the tilting cylinder 2 rotates periodically, with each rotation angle set to 180° and the rotation cycle set to 5 minutes. Through the periodic rotation of the tilting cylinder 2, the finishing drying chamber 4 and the quick drying chamber 5 are arranged vertically downwards in a cycle, and the material is eventually allowed to enter the quick drying chamber and the finishing drying chamber in turn for drying treatment. A central control unit 25 is fixedly installed on the frame 1, and the end of the quick-drying tank 5 is connected to a material valve 26; The central control unit 25 is a PLC controller, model Siemens S7-1200; The feed valve 26 is used to feed and discharge the raw materials for drying the popping droplets; A reciprocating frame 6 is slidably connected to the tilting cylinder 2, and a guide frame 37 is fixedly installed on the tilting cylinder 2. A guide groove is provided on the reciprocating frame 6 that is slidably connected to the guide frame 37. The tube shaft 3 is equipped with a reciprocating drive mechanism that drives the reciprocating frame 6 to perform cyclic amplitude reciprocating motion; The reciprocating drive mechanism includes a drive wheel 34 fixedly mounted on the tube shaft 3. Along the circumferential direction, the drive wheel 34 is alternately provided with three sector tooth segments 35 and three toothless arc surfaces. A toothed plate 36 is mounted on the side of the reciprocating frame 6. The three sector tooth segments 35 are alternately meshed with the toothed plate 36, and the transmission stroke of the three sector tooth segments 35 to the toothed plate 36 is different. A first spring 38 is mounted on the tilting cylinder 2. The other end of the first spring 38 is fixedly connected to the reciprocating frame 6. A second spring 39 is connected between the reciprocating frame 6 and the quick-drying can 5. In a preferred embodiment, the number of teeth of the three sector tooth segments 35 in the clockwise direction are 4, 5 and 6 teeth respectively, and the tooth pitch of each sector tooth segment 35 is the same. By setting the number of teeth of the three sector tooth segments 35 differently, the transmission stroke of the three sector tooth segments 35 to the tooth plate 36 is different. Specifically, because the three sector tooth segments have different numbers of 35 teeth, the driving strokes are 8mm, 10mm, and 12mm respectively, thus achieving variable amplitude reciprocating motion; By designing three sector segments 35 with different numbers of teeth on the drive wheel 34, the reciprocating stroke of the reciprocating frame 6 changes periodically and dynamically, breaking the limitations of traditional fixed-stroke reciprocating motion. The reciprocating frame 6 is rotatably connected to the stirring shaft 7, which is linked to the quick-drying tank 5, and the main shaft 8, which is linked to the fine-drying tank 4; The quick-drying can 5 is fixedly equipped with an upper gear ring 27, the fine-drying can 4 is fixedly equipped with a lower gear ring 28, and the reciprocating frame 6 is rotatably connected with a top shaft 29 and a bottom shaft 30 respectively. The top shaft 29 is equipped with an upper gear 31 that meshes with the upper gear ring 27, and the bottom shaft 30 is equipped with a lower gear 32 that meshes with the lower gear ring 28. In a preferred embodiment, the tooth height of the upper gear ring 27 is 8 times the tooth height of the upper gear 31, the tooth height of the lower gear ring 28 is 8 times the tooth height of the lower gear 32, a third synchronous belt is drivingly connected between the top shaft 29 and the stirring shaft 7, and a fourth synchronous belt is drivingly connected between the bottom shaft 30 and the main shaft 8. By setting the tooth height ratio between the upper gear ring 27 and the upper gear 31 and the tooth height ratio between the lower gear ring 28 and the lower gear 32, the stirring shaft 7 and the main shaft 8 can maintain rotation during the reciprocating movement of the reciprocating frame 6. Specifically, the transmission ratio of the upper gear ring 27 to the upper gear 31 is 10:1, and the transmission ratio of the lower gear ring 28 to the lower gear 32 is 8:1. By setting a specific transmission ratio, the stirring rod 9 of the quick-drying chamber and the main shaft 8 of the fine-drying chamber can obtain appropriate stirring speeds. The quick-drying stage achieves efficient material dispersion, and the fine-drying stage achieves fine circulating drying. Compared with the traditional fixed transmission ratio design, it significantly improves the adaptability of different drying stages and achieves the optimal balance between drying efficiency and drying quality. A stirring rod 9 is installed on the stirring shaft 7 at a position corresponding to the inside of the quick-drying tank 5. A fixed valve seat 10 is fixedly installed inside the tilting cylinder 2, and the fixed valve seat 10 is located between the quick-drying chamber and the fine-drying chamber. A valve shaft 11 is rotatably connected to the fixed valve seat 10, and the valve shaft 11 rotates synchronously with the stirring shaft 7. A hexagonal segment 33 is fixedly provided at the bottom of the stirring shaft 7. A hexagonal hole with open ends and slidably connected to the hexagonal segment 33 is provided inside the valve shaft 11. The cross-sectional shape of the hexagonal segment 33 and the hexagonal hole is a regular hexagon. A movable valve disc 49 is installed at the bottom of the valve shaft 11, and a disturbance rod 12 is arranged on its upper part. Valve holes 13 are arranged on both the movable valve disc 49 and the fixed valve seat 10. The axis of the valve hole 13 is parallel to the axis of the tilting cylinder 2. When the rotating drum 2 performs a rotating action, that is, when the material is transferred between the fast drying chamber and the fine drying chamber, due to the setting of the fixed valve seat 10 and the valve hole 13, after the rotating drum 2 completes the rotating action, the material in the fast drying chamber can slowly flow to the fine drying chamber or the material in the fine drying chamber can slowly flow to the fast drying chamber. Through the slow transfer of the material position, after the angle position of the rotating drum 2 is transferred, the fast drying chamber or the fine drying chamber can achieve fractional drying of the raw material to be dried for the popping droplets. By fractional drying, the drying efficiency is improved. Furthermore, the array design of the fixed valve seat 10 and the valve hole 13 enables the material to transition slowly between the fast drying chamber and the fine drying chamber, avoiding the accumulation and collision damage caused by the spillage of material during the turning process, and effectively protecting the structural integrity of the popping droplets. When the valve shaft 11 rotates synchronously with the stirring shaft 7, the disturbance rod 12 agitates the slow-flowing material a second time to prevent the material from clogging at the valve hole 13 and ensure that the material is evenly distributed to the target chamber. The fractional drying mode significantly improves the drying uniformity compared with the overall drying mode, and solves the technical problem of local over-drying or under-drying of materials in traditional equipment. The sliding fit between the hexagonal segment 33 and the hexagonal hole ensures the synchronous rotation of the valve shaft 11 and the stirring shaft 7, without affecting the reciprocating movement of the stirring shaft 7 driven by the reciprocating frame 6. This cleverly achieves the coordinated linkage between rotational motion and reciprocating motion, resulting in a compact structure and efficient function. A dispersion cylinder 14 and a reflux cylinder 15 are fixedly connected on the drying tank 4. A reflux pipe 16 and a discharge branch pipe 17 are connected between the dispersion cylinder 14 and the reflux cylinder 15 respectively. The axes of the dispersion cylinder 14 and the reflux cylinder 15 are parallel to the axis of the tilting cylinder 2. A dispersion shaft 18 coaxially arranged with the dispersion cylinder 14 and a material shaft 19 coaxially arranged with the return cylinder 15 are rotatably connected to the reciprocating frame 6. A first synchronous belt is driven to the main shaft 8. Both the dispersion shaft 18 and the material shaft 19 are driven to the first synchronous belt. Dispersion rods 20 are arrayed on the dispersion shaft 18 at positions corresponding to the inner side of the dispersion cylinder 14. Spiral conveying blades 21 are fixed on the material shaft 19 at positions corresponding to the inner side of the return cylinder 15. Both the dispersion cylinder 14 and the return cylinder 15 are arrayed with inner mesh holes 22. When the fine drying tank 4 is directly below the quick drying tank 5, the conveying direction of the spiral conveyor blade 21 is upward, which allows the raw material to be dried, the popping drop pellets, to circulate up and down in the dispersion cylinder 14 and the return cylinder 15. Through the realization of the up and down circulation effect, the raw material to be dried, the popping drop pellets, can be clearly separated when processed in the dispersion cylinder 14 and the return cylinder 15, thereby improving the fine drying effect of the raw material and significantly improving the drying uniformity of the raw material. When the tilting cylinder 2 is tilted 180°, that is, when the quick-drying tank 5 is directly below the fine-drying tank 4, the material flows to the quick-drying tank 5 under the action of gravity due to the connection between the dispersing cylinder 14 and the return cylinder 15 and the fine-drying tank 4. By cooperating with the spiral conveyor blade 21, the return pipe 16, and the discharge branch pipe 17, a closed-loop channel for the material to circulate up and down is constructed. The dispersing rod 20 efficiently disperses the material during the circulation process, effectively preventing the popping droplets from sticking together and clumping. The inner mesh holes 22 on the dispersion cylinder 14 and the return cylinder 15 not only ensure the smooth flow of hot air but also prevent material leakage, realizing the integrated operation of circulation, dispersion and drying. When the drying tank 4 is at the bottom, the material circulation allows each popping droplet to come into uniform contact with the hot airflow, improving the fine drying effect. When the material flows by gravity to the quick-drying tank 5 after being flipped, the loose state formed by the previous circulation and dispersion makes the agitation and drying of the quick-drying chamber more efficient. Compared with traditional static drying or single-direction conveying drying, this structure ensures both drying uniformity and drying efficiency, while protecting the particle integrity of the popping droplets. It also includes a heating system for the synchronous heating of the inner cavities of the drying tank 4 and the quick-drying tank 5.
[0022] The heating system includes a hot air blower 40 installed at the bottom of the frame 1, and the outlet port of the hot air blower 40 is connected to a hot air pipe 41. The outlet temperature of the hot air blower 40 is 75℃, the air volume is 150m³ / h, and the air inlet port of the hot air blower 40 is equipped with a filter. The outlet port of the hot air duct 41 is rotatably connected to a diversion ring 42. The diversion ring 42 is fixedly connected to a rotating shaft 24 at an adjacent position. Two air supply ring pipes 43 are fixedly connected to the diversion ring 42. The two air supply ring pipes 43 are rotatably connected to the drying can 4 and the quick-drying can 5, respectively. The quick-drying can 5 has an air guide chamber 44 inside. The outer wall of the air guide chamber 44 and the drying can 4 are both provided with arrays of ventilation holes 45 that communicate with the air supply ring pipes 43. The inner wall of the quick-drying can 5 is provided with arrays of hot spray holes 46 that communicate with the air guide chamber 44.
[0023] The heating system achieves synchronous heat delivery to the dispersion cylinder 14, return cylinder 15, quick-drying chamber, and fine-drying chamber through the linkage design of the diversion ring 42 and the air supply ring pipe 43. The structure of the diversion ring 42 being fixedly connected to the tilting shaft 24 and the air supply ring pipe 43 being rotatably connected to the fine-drying tank 4 and the quick-drying tank 5 ensures that the hot air delivery is uninterrupted during the rotation of the tilting cylinder 2, thus solving the problem of coordination between moving parts and fixed heat delivery parts. The array distribution of hot spray holes 46 and ventilation holes 45 allows hot air to evenly cover the entire drying chamber, forming a comprehensive and dead-angle-free thermal environment, avoiding uneven drying caused by local temperature differences. Temperature and humidity probe 47 and ventilation valve 48 are installed on the rotating cylinder 2. The data terminal of temperature and humidity probe 47 and the electrical control terminal of ventilation valve 48 are both connected to the central control unit 25.
[0024] The central control unit 25, together with the servo motor 23, hot air blower 40, temperature and humidity probe 47, and ventilation valve 48, constitutes a closed-loop control system. Temperature and humidity probe 47 collects temperature and humidity data inside the rotating cylinder 2 in real time and transmits the data to the central control unit 25. When the temperature is higher than the set 75℃, the central control unit 25 controls the hot air blower 40 to reduce the heating power and opens the ventilation valve 48 to ventilate and cool down. When the temperature is below the set lower limit of 60℃, control the hot air blower 40 to increase the heating power and close the ventilation valve 48; When the humidity is higher than 50%RH, control the ventilation valve 48 to increase the opening degree and increase the air speed of the hot air blower 40 to ensure that the chamber always maintains the optimal dry environment. Compared to the traditional manual monitoring and adjustment mode, this design improves the accuracy and timeliness of parameter control, reduces human error, and provides a stable environment for dual-chamber linkage drying. It enables seamless and precise switching of environmental parameters between the fast drying and fine drying stages, further enhancing the controllability and stability of the drying process and ensuring the consistency of product quality.
[0025] The specific steps for using this invention are as follows: When the dual-cavity linkage production and processing equipment for popping droplets of the present invention is working, the raw materials to be dried are first put into the material valve 26 at the end of the quick-drying tank 5. After the central control unit 25 is started, the two motors 23 drive the tube shaft 3 and the tilting drum 2 to rotate independently through the second synchronous belt. The active bevel gear on the tube shaft 3 meshes and drives the driven bevel gear ring of the fine drying tank 4 and the quick-drying tank 5 to rotate. At the same time, the tilting drum 2 rotates 180° periodically with a cycle of 5 minutes, so that the fine drying tank 4 and the quick-drying tank 5 switch vertically downward in a cycle, allowing the material to enter the fine drying chamber in the fine drying tank 4 and the quick drying chamber in the quick drying tank 5 in turn. When the tube shaft 3 rotates, the drive wheel 34 on it alternately meshes with the toothed plate 36 on the side of the reciprocating frame 6 through three sector tooth segments 35 with different numbers of teeth. With the guidance of the first spring 38, the second spring 39 and the guide frame 37, the reciprocating frame 6 is driven to perform cyclic amplitude reciprocating motion. During the movement of the reciprocating frame 6, the upper gear 31 on the top shaft 29 meshes with the upper gear ring 27 of the quick-drying tank 5, and the lower gear 32 on the bottom shaft 30 meshes with the lower gear ring 28 of the fine-drying tank 4. The third and fourth synchronous belts drive the stirring shaft 7 and the main shaft 8 to rotate respectively. The stirring rod 9 on the stirring shaft 7 efficiently disperses the material in the quick-drying chamber. The main shaft 8 drives the dispersing shaft 18 and the material shaft 19 to rotate through the first synchronous belt. The dispersing rod 20 on the dispersing shaft 18 disperses the material in the dispersing cylinder 14. The spiral conveying blade 21 on the material shaft 19, together with the return pipe 16 and the discharge branch pipe 17, realizes the material to circulate up and down between the dispersing cylinder 14 and the return cylinder 15, ensuring the uniformity of fine drying. When the rotating drum 2 is rotated, the fixed valve seat 10 between the fast drying chamber and the fine drying chamber realizes the slow material conversion through the array valve hole 13. The valve shaft 11 rotates with the stirring shaft 7, and the disturbance rod 12 on it prevents material blockage and ensures the drying of the quantity. Meanwhile, the hot air blower 40 of the heating system delivers air to the air guide chamber 44 of the quick-drying tank 5 and the fine-drying tank 4 through the hot air pipe 41, the diversion ring 42, and the air supply ring pipe 43. The hot air is evenly sprayed into the chamber through the hot spray hole 46 and the ventilation hole 45. The temperature and humidity probe 47 on the rotating drum 2 collects environmental parameters in real time and feeds them back to the central control unit 25. The central control unit 25 adjusts the ventilation valve 48 to maintain the optimal drying environment, and finally completes the dual-chamber linkage quick-drying and fine-drying integrated processing of the material.
