Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and more specifically to a single-cone spiral vacuum drying device and method based on adaptive control. Background Technology

[0002] The single-cone ribbon vacuum dryer based on adaptive control is an intelligent drying device that integrates a single-cone ribbon drying structure, vacuum environment, and adaptive control system. Its core is to collect key parameters such as material moisture content, temperature, ribbon speed, and vacuum degree in real time through sensors. The adaptive control algorithm automatically adjusts operating parameters such as ribbon stirring speed, heating temperature, and vacuum pumping rate according to the changes in material characteristics during the drying process. This solves the problems of traditional single-cone ribbon vacuum dryers that rely on fixed parameters, are prone to uneven drying, excessive energy consumption, or over-drying.

[0003] Existing adaptive control-based single-cone ribbon vacuum drying devices, when using a single-cone ribbon for material transport, can lead to agglomeration during the drying process if the heating temperature remains constant. This, combined with the continuous material transport by the single-cone ribbon and the constant internal transport space, severely impacts the drying effect. This is because the fixed temperature during single-cone ribbon drying cannot adapt to the drying requirements of different transport stages: initially, the temperature meets the evaporation needs of materials with high moisture content, but in later stages, it causes a dense, hard shell to quickly form on the material surface, hindering the escape of internal moisture. Furthermore, the fixed transport space causes materials to compress each other, preventing the hard shell from dispersing, and the fixed temperature cannot be adjusted according to the real-time state of the material, further exacerbating uneven moisture distribution. Ultimately, this results in agglomeration, affecting the looseness and drying uniformity, and also causing incomplete drying due to moisture trapped in the agglomerates, thus reducing the drying effect. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a single-cone spiral vacuum drying device and method based on adaptive control, which can effectively solve the problem that the material agglomeration occurs during the drying process due to the fixed heating temperature in the prior art, thus seriously affecting the drying effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a single-cone ribbon vacuum drying device based on adaptive control, comprising: Base; A hot stirring mechanism includes a stirring assembly disposed on the upper end face of a base, a conical barrel disposed at the bottom of the stirring assembly, multiple deformation components disposed inside the stirring assembly, and a transmission component disposed on the side of the stirring assembly. A cold dispersion mechanism includes a connecting barrel fixedly connected to the top of a stirring assembly. A conduction assembly is provided inside the connecting barrel, and multiple resonance components are arranged in a ring array on the inner wall of the connecting barrel. Each resonance component has at least two collision components inside. A conical stirring mechanism includes a drive assembly disposed on top of a transmission assembly. On the side of the drive assembly facing the transmission assembly and the stirring assembly, a power rod, a buffer, and a rotating shaft are arranged sequentially. The power rod is located inside the transmission assembly and is positioned accordingly. The rotating shaft is located inside the stirring assembly and is positioned accordingly. The power rod has multiple collision vibration components arranged in a linear array on its shaft. The rotating shaft has single and double helical stirring blades arranged alternately on its shaft, with the single helical stirring blades being larger than the double helical stirring blades.

[0006] A method for a single-cone spiral vacuum drying device based on adaptive control, comprising: drying at different temperatures during stirring, cooling and dispersing during re-falling, and irregular spiral stirring. Drying at different temperatures during stirring: By supplying different amounts of ignition gas to each pressurization zone through a booster and changing the gas pressure in each pressurization zone, the heat transfer effect and the degree of deformation of the deformation components in each pressurization zone are changed. This results in different amounts of heat received by each pressurization zone due to the different amounts of ignition gas stored in the corresponding tubes of the quick-heater. Consequently, different temperatures appear at the corresponding positions in the inner barrel. This prevents the single and double spiral blades of the conical stirring mechanism from heating and drying the material at a constant temperature. At the same time, because the gas pressure in the pressurization zone changes the degree of deformation of the deformation components at the corresponding positions, different degrees of unevenness appear at the corresponding positions in the inner barrel, thus changing the spatial changes of the material during the transmission process. Cooling and dispersing during re-fall: After the conical stirring mechanism completes one material transfer, air is supplied to the resonance zone by the air booster and discharged from the pressure relief valve, thus realizing the flow of air in the resonance zone. This creates an airflow, which then collides with the resonance components in the resonance zone. As the resonance components are impacted by the airflow, they vibrate due to mutual collisions. Simultaneously, the thrust of the single and double helical blades on the rotating shaft of the conical stirring mechanism during material transfer pushes the material to the transmission component. Since the transmission component is connected to the collision vibration component, it applies vibration to the collision vibration component, thereby breaking and dispersing the material that has completed one transfer. At the same time, the airflow also cools the transmission component, thus cooling the material. Irregular spiral stirring: The drive motor drives the power rod to rotate, and the power rod drives the rotating shaft to rotate through the buffer, so that the rotation speed of the power rod is consistent with that of the drive motor. Because of the buffer, the vibration of the rotating shaft located in the collision vibration component of the power rod will not be transmitted to the power rod. The material is transferred through the single and double spiral stirring blades that rotate synchronously with the power rod.

[0007] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By utilizing the stirring component, deformation component, and conveying component in the thermal stirring mechanism, the drying temperature and conveying space of the material are altered during the conveying process, thus preventing the material from maintaining a constant temperature during drying. The stirring component forms a pressurization zone, and the conveying component changes the heat transfer effect of the gas conveyed in each pressurization zone to regulate the temperature of each zone. Simultaneously, the gas pressure delivered to the pressurization zone changes the deformation effect of the deformation component, thereby creating different deformations in each pressurization zone and altering the material conveying space. The thermal stirring mechanism achieves this through the synergistic effect of stirring, deformation, and the conveying component. It can change the drying temperature and transmission space during material transfer, avoiding the drawbacks of maintaining a single temperature throughout the process. The stirring component forms a pressurization zone, and the transmission component can change the heat transfer effect of the gas transported in each pressurization zone to achieve regional temperature regulation, adapting to the drying needs of different material transfer stages, and preventing the formation of a hard shell on the material surface and the obstruction of internal moisture escape caused by a fixed temperature. At the same time, the gas pressure in the pressurization zone will change the deformation effect of the deformation component, forming a concave-convex transmission space in different pressurization zones. By using the change in the size of the space, the phenomenon of material agglomeration is avoided, thereby improving the uniformity of material drying and the overall drying effect.

[0008] 2. The cold dispersion mechanism utilizes the conduction, resonance, and collision components to disperse the material after one cycle of material transfer and drying in the conical stirring mechanism. This prevents clumping of material during subsequent transfers and drying cycles, which would hinder the drying process. Specifically, the resonance component utilizes the continuous impact of airflow generated as gas passes through the resonance zone, causing it to shake. This, in turn, causes the collision components inside the resonance component to continuously collide, generating vibration. The conduction component amplifies and converges this vibration, applying it to the conical stirring mechanism to achieve dispersion of the material after one cycle of material transfer. The cold dispersion mechanism, through the synergistic effect of conduction, resonance, and collision components, can effectively disperse the material dried by the conical stirring mechanism in one pass, preventing agglomerated material from entering the next drying process and affecting the drying effect. The resonance component is vibrated by the collision of gas flow. The resonance component at different positions will produce different vibrations. Combined with the continuous impact of the collision component, the vibration is amplified and converged by the conduction component and applied to the conical stirring mechanism. It can apply vibration force to the material from multiple dimensions and different intensities, more fully breaking up agglomerates, and further ensuring the smooth progress of the subsequent drying process and the drying quality.

[0009] 3. Through the collision vibration component, rotating shaft, single and double spiral stirring blades, and drive component in the conical stirring mechanism, the material is spirally transported in the hot stirring mechanism and vibrated and dispersed in the cold dispersion mechanism. The drive motor drives the power rod to rotate, and the power rod is connected to the rotating shaft via a buffer, which prevents the power rod from affecting the rotation of the rotating shaft. The single and double spiral stirring blades located in the power rod, due to their specifications and the number of spirals, result in inconsistent material speeds during transport. This is to accommodate the uneven transport space and varying temperatures in the pressurization zone. The conical stirring mechanism utilizes the collision vibration component, The coordinated operation of the rotating shaft, single and double stirring spiral blades, and drive components ensures the stability of material transfer and mixing by leveraging the linkage of the drive motor, power rod, and buffer, ensuring that the power rod does not affect the rotational speed output of the rotating shaft. Furthermore, the difference in material transfer speed between single and double stirring spiral blades due to their different specifications and number of spirals, combined with the uneven transfer space and varying temperatures within the pressurization zone of the hot stirring mechanism, adapts to the needs of different drying stages. Simultaneously, it can be combined with a collision vibration component to complete the spiral transfer of materials within the hot stirring mechanism and the vibration-breaking and dispersion within the cold dispersion mechanism, further preventing material agglomeration and improving drying uniformity and overall drying effect.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0014] The present invention will be further described below with reference to embodiments.

[0015] Example: Refer to Figures 1 to 16 The single-cone spiral vacuum drying device based on adaptive control includes: a base 1, a hot stirring mechanism 2 and a cold dispersion mechanism 3, and a conical stirring mechanism 4. The hot stirring mechanism 2 includes a stirring component 21 disposed on the upper end face of the base 1. A conical barrel 22 is disposed at the bottom of the stirring component 21. Multiple deformation components 23 are disposed inside the stirring component 21. A transmission component 25 is disposed on the side of the stirring component 21.

[0016] The cold dispersion mechanism 3 includes a connecting barrel 31 fixedly connected to the top of the stirring assembly 21. A conduction assembly 32 is provided inside the connecting barrel 31. Multiple resonance components 33 are arranged in a ring array on the inner wall of the connecting barrel 31. Each resonance component 33 is provided with at least two collision components 34 inside.

[0017] The conical stirring mechanism 4 includes a drive assembly 48 disposed on the top of the transmission assembly 32. On the side of the drive assembly 48 facing the transmission assembly 32 and the stirring assembly 21, a power rod 41, a buffer 47 and a rotating shaft 43 are arranged in sequence. The power rod 41 is located inside the transmission assembly 32 and is in a corresponding position. The rotating shaft 43 is located inside the stirring assembly 21 and is in a corresponding position. The rod of the power rod 41 is arranged in a linear array with multiple collision vibration components 42. The rod of the rotating shaft 43 is arranged with single stirring spiral blades 45 and double spiral stirring blades 46 alternately. The single stirring spiral blade 45 is larger than the double spiral stirring blade 46.

[0018] In this process, the stirring component 21 in the hot stirring mechanism 2 provides different temperatures to the materials conveyed in the conical stirring mechanism 4, and the deformation component 23 located inside the stirring component 21 changes the space in which the materials are conveyed within the stirring component 21. When the conical stirring mechanism 4 completes one pass of materials through the stirring component 21, it will further convey the materials to the position of the conduction component 32 inside the connecting barrel 31 of the cold dispersion mechanism 3. The conduction component 32 is vibrated by the airflow through the resonance component 33 inside it, thereby using vibration to break and disperse the materials after one drying cycle, so as to avoid the material conveyed by the conical stirring mechanism 4 from agglomerating during the drying process under the action of the stirring component 21 and the deformation component 23, which would affect the drying effect of the next cycle. Since the drive component 48 drives the power rod 41 to rotate, and the power rod 41 drives the rotating shaft 43 to rotate through the buffer 47, the rotating shaft 43 synchronously drives the single stirring spiral blade 45 and the double spiral stirring blade 46 to rotate, so as to realize the material transmission.

[0019] Reference Figures 1 to 4 , Figure 9 A controller is provided on the side of the base 1; The stirring assembly 21 includes an outer barrel 211 and an inner barrel 212 fixedly connected to the upper end face of the base 1, with the inner barrel 212 sleeved inside the outer barrel 211. A plurality of sealing rings 213 are linearly arrayed and fixedly connected between the outer barrel 211 and the inner barrel 212, and two adjacent sealing rings 213 form a pressurization zone between the outer barrel 211 and the inner barrel 212.

[0020] The number and position of the deformation components 23 correspond one-to-one with the pressurization zones. Each deformation component 23 includes a fixing ring 231 fixedly connected to the inner wall of the inner barrel 212 located in the pressurization zone. An elastic ring 232 is fixedly connected to the center of the fixing ring 231.

[0021] Multiple sealing rings 213 are used to achieve multi-layer separation between the outer barrel 211 and the inner barrel 212, and multiple independent pressurization zones are formed between the outer barrel 211 and the inner barrel 212. By delivering different amounts of gas to the pressurization zones at different locations, the gas pressure in the different pressurization zones is changed, thereby adjusting the deformation of the elastic ring 232 of the deformation component 23.

[0022] Reference Figures 6 to 8 Each pressurization zone has a spiral tube 24 wound inside. The transmission component 25 includes multiple inlet valves 251 and multiple outlet valves 252 fixedly connected to the side of the outer barrel 211. The positions and descriptions of the inlet valves 251, outlet valves 252 and spiral tubes 24 are one-to-one. The input end of the spiral tube 24 passes through the outer barrel 211 and is connected to the output end of the inlet valve 251. The output end of the spiral tube 24 passes through the outer barrel 211 and is connected to the input end of the outlet valve 252. The input ends of each inlet valve 251 are connected to a multi-inlet pipe 253. The output ends of each outlet valve 252 are connected to a multi-outlet pipe 254.

[0023] Heating liquid is used to flow in the loop pipe 24 in each pressurization zone to heat each pressurization zone. The inlet-outlet pipe 253 delivers the heating liquid to the loop pipe 24 through the inlet valve 251. After the heating liquid is connected in the loop pipe 24, it is discharged through the outlet valve 252 and the outlet-outlet pipe 254.

[0024] Reference Figures 3 to 5 Multiple pressure detectors 26 are fixedly connected to the side of the outer barrel 211 in a linear array. The number and position of each pressure detector 26 correspond to the number of pressurization zones. The pressure detectors 26 are electrically connected to the controller. The output end of each pressure detector 26 is connected to the interior of the corresponding pressurization zone. The input end of each pressure detector 26 is fixedly connected to a gas control valve 27. The input ends of each gas control valve 27 are connected to a multi-port pipe 28.

[0025] The conical barrel 22 and the inner barrel 212 are in corresponding positions and connected to each other. The other end of the conical barrel 22 is fixedly connected to the discharge valve 221, and the discharge valve 221 is electrically connected to the controller. The output end of the discharge valve 221 is fixedly connected to the conveying pipe 222.

[0026] Multiple pressure detectors 26 are used to detect the pressure in the corresponding pressurization zone, while multi-port pipe 28 is used to deliver pressurized gas to each pressurization zone. The corresponding gas control valve 27 in each pressurization zone is used to control the amount of gas delivered to the corresponding pressurization zone by multi-port pipe 28. Conical barrel 22 is used to collect the dried material and further transfer the dried material through discharge valve 221 and conveying pipe 222.

[0027] Reference Figures 10 to 13The conducting component 32 includes a vibrating barrel 321 fitted inside the connecting barrel 31, and the vibrating barrel 321 is connected to the inner barrel 212. The top and bottom of the vibrating barrel 321 and the connecting barrel 31 are sealed, and a resonance zone is formed between the vibrating barrel 321 and the connecting barrel 31. Multiple first resonant plates 322 are fixedly connected to the outer peripheral surface of the vibrating barrel 321 in a ring array, and multiple guide blocks 323 are fixedly connected to the inner peripheral surface of the vibrating barrel 321 in a ring array.

[0028] Each resonant component 33 includes an elastic connecting plate 331 fixedly connected to the inner circumferential surface of the connecting barrel 31 facing the resonant region. A hollow plate 332 is fixedly connected to the other side of the elastic connecting plate 331. Multiple second resonant plates 333 are fixedly connected in a linear array along the length direction on the other side of the hollow plate 332.

[0029] The collision assembly 34 includes an elastic rod 341 fixedly connected in the length direction inside the hollow plate 332, and at least two impact balls 342 are fixedly connected to the rod body of the elastic rod 341 in a linear array.

[0030] The vibration barrel 321 and the connecting barrel 31 in the transmission component 32 together form a resonance zone. The first resonance plate 322 located in the resonance zone is used to generate a resonant vibration effect with the resonance component 33 in the resonance zone and transmit the vibration force to the vibration barrel 321. The vibration barrel 321 uses the guide block 323 to converge the transmitted vibration force. The hollow plate 332 and the second resonance plate 333 in the collision component 34 are blocked by the impact collision of the flowing gas in the resonance zone.

[0031] Reference Figure 4 , Figure 10 A connecting pipe 36 is fixedly connected to the side of the connecting barrel 31 located in the resonance zone, and the input end of the connecting pipe 36 is connected to the interior of the resonance zone. A pressure relief valve 35 is fixedly connected to the top of the connecting barrel 31 located in the resonance zone, and the input end of the pressure relief valve 35 is connected to the interior of the resonance zone. The pressure relief valve 35 is also electrically connected to the controller. The drive assembly 48 includes a sealing cover 481 fixedly connected to the upper end face of the vibrating barrel 321. A drive motor 482 is fixedly connected to the center of the upper end face of the sealing cover 481. A vacuum device 483 is fixedly connected to the upper end face of the sealing cover 481, and the input end of the vacuum device 483 passes through the sealing cover 481 and communicates with the interior of the vibrating barrel 321. A feeding port 484 is fixedly connected to the upper end face of the sealing cover 481, and the output end of the feeding port 484 communicates with the interior of the vibrating barrel 321. The drive motor 482 and the vacuum device 483 are both electrically connected to the controller.

[0032] Gas is transported to the resonance zone using the connecting pipe 36, and when the gas reaches the pressure relief valve 35, the gas in the resonance zone is released, thereby forming a continuous airflow generated by the transport and release of gas in the resonance zone. The airflow is then used to vibrate the resonance component 33 in the resonance zone. At the same time, the airflow is also used to cool the resonance zone, thereby cooling the material entering the vibrating barrel 321.

[0033] Reference Figures 14 to 16 The power rod 41 is rotatably connected to the sealing cover 481 located at the bottom of the drive motor 482, and the output end of the drive motor 482 is fixedly connected to the power rod 41. The collision vibration assembly 42 includes a bearing 421 rotatably connected to the body of the power rod 41. Multiple pairs of vibration rods 422 corresponding to the number of guide blocks 323 are fixedly connected to the outer circumferential surface of the bearing 421 in an annular array. The other side of each pair of vibration rods 422 is fixedly connected to the side of the guide block 323. The end of the power rod 41 away from the drive motor 482 is fixedly connected to one end of the buffer 47, and the other end of the buffer 47 is fixedly connected to the rotating shaft 43.

[0034] The drive motor 482 drives the power rod 41 to rotate. As the power rod 41 rotates, it drives the rotating shaft 43 to rotate synchronously through the buffer 47. The collision vibration assembly 42 is connected to the power rod 41 through the bearing 421, so that the vibration rod 422 is fixed to the bearing 421 and the guide block 323. The guide block 323 then applies the concentrated vibration to the vibration rod 422. After the single stirring spiral blade 45 and the double spiral stirring blade 46 have completed one drying of the material, the material will enter the vibrating drum 321 by the inertial force during the transmission.

[0035] Reference Figures 14 to 15 The double helical stirring blade 46 is wound in a ring around the body of the rotating shaft 43 by a support rod. Multiple connecting rods 44 are wound and fixedly connected to the body of the rotating shaft 43. The single stirring helical blade 45 is fixedly connected to the other end of the connecting rod 44. A conical dispersion barrel 5 is fixedly connected to the upper end face of the base 1. The other end of the conveying pipe 222 is connected to the input end of the conical dispersion barrel 5. A booster 6 is fixedly connected to the side of the base 1, and the booster 6 is electrically connected to the controller. The booster 6 stores heat-insulating gas inside. The output end of the booster 6 is fixedly connected to a booster pipe 61, and the other end of the booster pipe 61 is connected to the input end of the multi-port pipe 28.

[0036] The rotating shaft 43 drives the single stirring spiral blade 45 and the double spiral stirring blade 46 to rotate. Since the single stirring spiral blade 45 is larger than the double spiral stirring blade 46, the single stirring spiral blade 45 can transport more material. The double spiral stirring blade 46 is smaller than the single stirring spiral blade 45, but it has two spiral stirring blades 46, so it can flip the material during transport.

[0037] Reference Figures 1 to 2 An air booster 8 is fixedly connected to the other side of the base 1. The other end of the air booster 8 is connected to the output end of the connecting pipe 36. A accelerator 7 is fixedly connected to one side of the base 1 in the width direction. An input pump 71 and an output pump 73 are fixedly connected side by side to the upper end face of the accelerator 7. The input end of the input pump 71 is fixedly connected to the liquid outlet pipe 72, and the other end of the liquid outlet pipe 72 is connected to the heating end of the accelerator 7. The output end of the input pump 71 is connected to the input end of the one-in-multiple-outlet pipe 253. The output end of the output pump 73 is fixedly connected to the liquid inlet pipe 74. The other end of the liquid inlet pipe 74 is connected to the return end of the accelerator 7. The input end of the output pump 73 is connected to the input end of the one-outlet-multiple-inlet pipe 254.

[0038] The air booster 8, the accelerator 7, the input pump 71, and the output pump 73 are all electrically connected to the controller; The air booster 8 draws in outside air and then delivers it to the resonance zone through the connecting pipe 36. This creates an airflow within the resonance zone, which in turn heats the liquid inside the accelerator 7 and controls the heating temperature. The heated liquid is drawn in through the outlet pipe 72 of the input pump 71. The heated liquid drawn in by the input pump 71 is then delivered through the one-in-multiple-outlet pipe 253 to the inlet valve 251 in the corresponding temperature boosting zone. The inlet valve 251 then delivers the heated liquid into the loop pipe 24.

[0039] The working principle of this invention is as follows: Step 1: First, the operator opens the feeding port 484 and slowly pours the material to be dried into the feeding port 484. At this time, the material slides down the inner wall of the vibrating drum 321 to the bottom of the inner drum 212 (the feeding amount is controlled within 80% of the rated processing capacity of the equipment to avoid excessive material clogging the transmission channel). After the material is poured in, the feeding port 484 is closed again. Then, the operator starts the vacuum device 483 through the controller. After starting, the vacuum device 483 continuously extracts the air inside the vibrating drum 321 and the connected inner drum 212 to maintain the vacuum environment required for material drying and help the moisture escape quickly.

[0040] Then, the operator starts the drive motor 482 via the controller. As the drive motor 482 starts, it drives the power rod 41 to rotate. The power rod 41 transmits power to the rotating shaft 43 through the buffer 47 at the end. This allows the rotating shaft 43 to synchronously drive the single stirring spiral blade 45 and the double spiral stirring blade 46, which are installed alternately on the shaft, to rotate. Since the single stirring spiral blade 45 is fixed to the shaft of the rotating shaft 43 by the connecting rod 44, and the double spiral stirring blade 46 is wrapped around the shaft of the rotating shaft 43 by the support rod, the two are staggered and the single stirring spiral blade 45 is larger than the double spiral stirring blade 46. Therefore, when the single stirring spiral blade 45 and the double spiral stirring blade 46 rotate synchronously with the rotating shaft 43, the single stirring spiral blade 45 is responsible for the stable conveying of a large amount of material, and the double spiral stirring blade 46 improves the uniformity of material transmission with its double spiral structure. Together, they push the material upward along the inner wall of the inner barrel 212.

[0041] Then, the staff sets the target heating temperature of the accelerator 7 through the controller. At this time, the heating element inside the accelerator 7 is activated to heat the heat transfer liquid inside. The temperature sensor inside the accelerator 7 provides real-time temperature data. After reaching the set temperature, it automatically maintains a constant temperature. Subsequently, the input pump 71 is activated and draws the heating liquid inside the accelerator 7 through the liquid outlet pipe 72. After being diverted through the one-inlet-multiple-outlet pipe 253, it is delivered to the loop pipe 24 of each pressurization zone through the multiple liquid inlet valves 251 on the side of the outer tank 211. The liquid flows in a serpentine manner in the loop pipe 24. After fully releasing the heat, the output pump 73 draws the cooled liquid through the one-outlet-multiple-inlet pipe 254 and the liquid outlet valve 252. The liquid flows back to the accelerator 7 through the liquid inlet pipe 74 for reheating, forming a closed loop.

[0042] Step 2: Simultaneously with the start-up of the accelerator 7, the booster 6 also starts. The booster 6 contains insulating gas. The high-pressure insulating gas (e.g., 0.1-0.6 MPa) generated upon startup is transported via the booster pipe 61 to the multi-port pipe 28. The multi-port pipe 28 then distributes the high-pressure insulating gas to gas control valves 27 corresponding to each booster zone (e.g., three booster zones from top to bottom: zone 1, zone 2, and zone 3). Based on the principle in heat transfer that "the amount of insulating medium filling is positively correlated with thermal resistance," the insulating gas flows through the loop pipe 2... 4. A heat insulation layer is formed around the perimeter. The more filling, the greater the thermal resistance, and the weaker the heat transfer from the U-shaped tube 24 to the pressurization zone, or even the complete blockage of heat transfer. The operator presets the target air pressure according to the material drying requirements through the controller on the side of the base 1, such as: 0.1MPa for zone 1, 0.2MPa for zone 2, and 0.3MPa for zone 3. Meanwhile, the air pressure detectors 26 on the side of the outer barrel 211, corresponding to each pressurization zone, detect the air pressure data in real time and transmit it synchronously to the controller. Thus, the controller automatically adjusts the air pressure according to the difference between the real-time air pressure and the preset value. The opening of control valve 27 delivers a small amount of insulating gas to zone 1 (approximately 30% of the pressurization zone volume), a medium amount of insulating gas to zone 2 (approximately 50%), and a large amount of insulating gas to zone 3 (approximately 80%). Ultimately, due to the limited amount of insulating gas in zone 1, heat transfer through the U-shaped pipe 24 is weakly obstructed, maintaining the temperature at position 212 of the inner drum at 75-80℃, suitable for the rapid evaporation of moisture during the high moisture content stage of the material. In zone 2, the amount of insulating gas is moderate, and heat transfer is partially obstructed, maintaining the temperature at 65-70℃, suitable for the medium-term slow evaporation of moisture. The internal moisture needs to be released slowly; Zone 3 has a lot of insulating gas, which greatly hinders heat transfer and lowers the temperature to 60-65℃, preventing the material from forming a hard shell due to high temperature later; at the same time, according to the principle of hydrostatic pressure transmission, the air pressure in each pressurization zone vertically squeezes the elastic ring 232 of the inner wall deformation component 23 of the inner barrel 212. Zone 1 has low air pressure and the elastic ring 232 bulges slightly; Zone 2 has medium air pressure and the bulge is moderate; Zone 3 has high air pressure and the bulge is obvious, so that the inner wall of the inner barrel 212 forms a dynamic transmission space with different concave and convex shapes, reducing the material from being squeezed and agglomerated.

[0043] In this process, the material enters the inner tank 212 under the coordinated push of a single stirring spiral blade 45 and a double spiral stirring blade 46. Based on the principle that "the thrust of the spiral blade is positively correlated with its size, and the transmission efficiency is related to the spiral structure," the single stirring spiral blade 45, due to its larger size, provides stronger conveying force, while the double spiral stirring blade 46, with its annular winding double spiral structure, improves the uniformity of material distribution. The alternating rotation of the two blades allows the material to flow through three pressurization zones in sequence. Combining the principle of heat transfer that "the amount of insulating medium filling is positively correlated with thermal resistance," the first pressurization zone only conveys 30% of the volume of insulating gas, and the heat transfer through the U-shaped tube 24 is weakly hindered. The high temperature of 75-80℃ causes the surface moisture of the material (in the high moisture content stage) to vaporize rapidly, and the vacuum environment accelerates the escape of water vapor. The material then enters the second pressurization zone, where 50% of the volume of insulating gas is conveyed. The insulating gas creates moderate thermal resistance, and the mild temperature of 65-70℃ allows the internal moisture of the material to slowly diffuse to the surface, avoiding uneven moisture distribution. When it reaches the third pressurization zone, the 80% volume of insulating gas significantly blocks heat, and the low temperature of 60-65℃ prevents the formation of a hard shell on the material surface. At the same time, according to the principle of hydrostatic pressure, the air pressure of 0.1MPa, 0.2MPa, and 0.3MPa in the three pressurization zones causes the elastic ring 232 to bulge slightly, moderately, and significantly, respectively. The inner wall of the inner barrel 212 forms a differentiated concave-convex space, and the material is continuously squeezed and loosened during transportation. In addition, the difference in transportation speed brought about by the single and double spiral stirring blades disrupts the material agglomeration conditions and avoids clumping. Ultimately, the material is dried uniformly from the outside to the inside, maintaining good looseness.

[0044] Step 3: Simultaneously with the activation of booster 6, the operator also activates air booster 8 via the controller. Air booster 8 draws in outside air and continuously delivers it through connecting pipe 36 to the resonance zone between connecting tank 31 and vibrating tank 321. The operator sets the pressure relief valve 35 to a pressure of 0.2 MPa via the controller. When the internal air pressure in the resonance zone reaches the set value, the pressure relief valve 35 automatically opens to release air, creating a continuous airflow within the resonance zone. This airflow then impacts the resonant... The second resonant plate 333 of the vibration assembly 33 causes the hollow plate 332 to swing left and right along the elastic connecting plate 331, which in turn causes the impact balls 342 on the elastic rod 341 inside the hollow plate 332 to collide with each other as they swing, and to impact the inner wall of the hollow plate 332 to generate high-frequency vibration. The vibration is transmitted through the second resonant plate 333 to the first resonant plate 322 on the outer periphery of the vibration barrel 321, and the vibration intensity is amplified through the resonance effect. Finally, it is converged and transmitted through the guide block 323 to the vibration rod 422 of the collision vibration assembly 42, so that the vibration rod 422 vibrates at high frequency.

[0045] In this process, the material is pushed upwards along the inner barrel 212 to the top by the combined action of a single stirring spiral blade 45 (fixed to the rotating shaft 43 by a connecting rod 44) ​​and a double spiral stirring blade 46 (wound around the rotating shaft 43 by a support rod). Based on the mechanical principle of "spiral transmission thrust superimposed on material inertia", the material gains continuous kinetic energy and smoothly enters the vibrating barrel 321 connected to the inner barrel 212. At this time, when the material collides with the high-frequency vibrating rod 422, based on the principle of "vibration energy breaking agglomerates", the vibration force overcomes the cohesive force of the material agglomerates, breaking up any possible agglomerates into dispersed particles. At the same time, according to the heat exchange principle of "airflow carrying away heat", the continuously flowing airflow in the resonance zone exchanges heat with the vibrating barrel 321, quickly carrying away the heat from the vibrating barrel 321 and the material inside, reducing the material temperature from 60-80℃ to 40-50℃, thus preventing the material particles from agglomerating again due to the high temperature environment.

[0046] Special Note: The buffer 47 is fixedly connected at one end to the power rod 41 and at the other end to the rotating shaft 43. Based on the principle of "elastic damping vibration isolation", its internal elastic components can efficiently transmit power, so that the rotating shaft 43 and the power rod 41 rotate synchronously, ensuring that the single stirring spiral blade 45 and the double spiral stirring blade 46 stably transmit materials. At the same time, the elastic components can absorb and dissipate the high-frequency vibration energy of the collision vibration assembly 42 through deformation and damping characteristics, blocking the transmission path of vibration from the power rod 41 to the rotating shaft 43, and avoiding vibration affecting the smooth operation of the rotating shaft 43. The collision vibration assembly 42 is rotatably connected to the power rod 41 through the bearing 421 and is fixed only to the guide block 323 of the vibrating barrel 321 through the vibrating rod 422. It only receives the vibration transmitted by the guide block 323 for material crushing and will not rotate synchronously with the rotation of the power rod 41, further isolating the transmission of vibration to the rotating shaft 43 and ensuring the stability of material transmission and drying.

[0047] In this process, the cooled and dispersed material falls back to the bottom of the inner barrel 212 under gravity from the bottom of the vibrating barrel 321. It is then picked up again by the single stirring spiral blade 45 and the double spiral stirring blade 46 and continues to be transported upwards, repeating the above drying and dispersion process. Meanwhile, the staff monitors the feedback data of the moisture content sensor (which is existing technology and is not shown in the figure) in the inner barrel 212 in real time through the controller. Based on the change in moisture content, the staff dynamically adjusts the gas input of each pressurization zone and the heating temperature of the accelerator 7. When the moisture content of the material drops below 5%, the drying is considered complete. When the controller shows that the material has been dried, the staff issues a discharge command through the controller, and the discharge valve 221 opens automatically. The dried material is collected in the conical barrel 22 and transported to the conical dispersion barrel 5 through the conveying pipe 222. After being buffered and dispersed twice in the conical dispersion barrel 5, the material is discharged from the bottom discharge end. The staff places a clean collection container at the discharge end to receive the dried material and randomly selects some material during the collection process.

[0048] A method for a single-cone spiral vacuum drying device based on adaptive control, comprising: drying at different temperatures during stirring, cooling and dispersing during re-falling, and irregular spiral stirring. Drying at different temperatures during stirring: Different amounts of ignition gas are supplied to each pressurization zone by the intensifier 6, and the air pressure in each pressurization zone is changed to change the heat transfer effect of different pressurization zones and the degree of deformation of the deformation component 23 in each pressurization zone. As a result, when the heat exchanger 7 delivers heat to the loop tube 24 in each pressurization zone, the loop tube 24 in the corresponding pressurization zone will receive different amounts of heat due to the different amounts of ignition gas stored. This will cause different temperatures in the inner barrel 212 corresponding to the pressurization zone. When the single stirring spiral blade 45 and double spiral stirring blade 46 of the conical stirring mechanism 4 transfer the material, the heating and drying temperature of the material will not remain constant. At the same time, since the air pressure in the pressurization zone will change the degree of deformation of the deformation component 23 at the corresponding position, different degrees of unevenness will also appear in the inner barrel 212 corresponding to the pressurization zone, thereby changing the spatial changes of the material during the transfer process.

[0049] Cooling and dispersing during re-fall: After the conical stirring mechanism 4 completes one material transfer, air is supplied to the resonance zone by the air booster 8 and discharged from the pressure relief valve 35, thereby realizing the flow of air in the resonance zone and forming an airflow. The airflow then collides with the resonance component 33 in the resonance zone. As the resonance component 33 is colliding with the airflow, the collision component 34 vibrates due to the collision between the resonance components 33. At the same time, the thrust of the single stirring spiral blade 45 and the double spiral stirring blade 46 of the rotating shaft 43 in the conical stirring mechanism 4 when transferring the material pushes the material to the position of the transmission component 32. Since the transmission component 32 is connected to the collision vibration component 42, the transmission component 32 applies vibration to the collision vibration component 42, thereby realizing the collision vibration component 42 breaking and dispersing the material that has completed one transfer. At the same time, the flow of air also cools the transmission component 32, thereby cooling the material.

[0050] Irregular spiral stirring: The drive motor 482 drives the power rod 41 to rotate, and the power rod 41 drives the rotating shaft 43 to rotate through the buffer 47, so that the rotation speed of the power rod 41 is consistent with that of the drive motor 482. Because of the buffer 47, the vibration of the rotating shaft 43 located in the collision vibration component 42 of the power rod 41 will not be transmitted to the power rod 41. The material is transferred through the single stirring spiral blade 45 and the double spiral stirring blade 46 that rotate synchronously with the power rod 41.

10. A method for an adaptive control-based single-cone spiral ribbon vacuum drying apparatus, used in the adaptive control-based single-cone spiral ribbon vacuum drying apparatus according to any one of claims 1-9, characterized in that, This method includes: drying at different temperatures during stirring, cooling and dispersing during re-falling, and irregular spiral stirring. Drying at different temperatures during stirring: By supplying different amounts of heat-inducing gas to each pressurization zone through the pressurizer (6) and changing the air pressure in each pressurization zone, the heat transfer effect of different pressurization zones and the degree of deformation of the deformation component (23) in each pressurization zone are changed. This allows the heat received by each pressurization zone to be different due to the storage of different amounts of heat-inducing gas in the corresponding spiral tube (24) of the pressurization zone. Consequently, different temperatures appear in the inner barrel (212) at the position corresponding to the pressurization zone. This prevents the heating and drying temperature of the material from remaining constant when the single stirring spiral blade (45) and double spiral stirring blade (46) of the conical stirring mechanism (4) transfer the material. At the same time, since the air pressure in the pressurization zone changes the degree of deformation of the deformation component (23) at the corresponding position, different degrees of concavity and convexity appear in the inner barrel (212) at the position corresponding to the pressurization zone, thereby changing the spatial changes of the material during the transfer process. Cooling and dispersing during re-fall: After the conical stirring mechanism (4) completes one material transfer, air is transferred into the resonance zone by the air booster (8) and discharged from the pressure relief valve (35), thereby realizing the flow of air in the resonance zone, which will form an airflow in the resonance zone, and then use the airflow to achieve collision with the resonance component (33) in the resonance zone. As the resonance component (33) is hit by the airflow, the collision component (34) will vibrate due to the collision between the resonance components (33). At the same time, the conical stirring mechanism (4) The thrust of the single stirring spiral blade (45) and the double spiral stirring blade (46) of the rotating shaft (43) when transmitting materials pushes the materials to the position of the transmission component (32). Since the transmission component (32) is connected to the collision vibration component (42), the transmission component (32) applies vibration to the collision vibration component (42), thereby enabling the collision vibration component (42) to break and disperse the materials that have completed one transmission. At the same time, the airflow also cools the transmission component (32), thereby cooling the materials. Irregular spiral stirring: The drive motor (482) drives the power rod (41) to rotate, and the power rod (41) drives the rotating shaft (43) to rotate through the buffer (47), so that the rotation speed of the power rod (41) is consistent with that of the drive motor (482). Because of the buffer (47), the vibration of the rotating shaft (43) in the collision vibration component (42) located in the power rod (41) will not be transmitted to the power rod (41). The material is transferred through the single stirring spiral blade (45) and the double spiral stirring blade (46) that rotate synchronously with the power rod (41).
