Description

Technical Field

[0001] This application relates to the field of spray drying technology, and in particular to a multifunctional atomizing dryer. Background Technology

[0002] Currently, atomizing dryers are mainly used in the pharmaceutical industry to manufacture products such as antibiotics, microcapsules, fillers, and pigments. In the food industry, they are mainly used to manufacture products such as milk powder, protein powder, and fruit juice powder. They can also be used for drying pesticides and chemical raw materials.

[0003] In related technologies, an atomizing dryer includes a cylinder, nozzles, a feed pipe, a hot air pipe, and a discharge pipe. The hot air pipe is installed at one end of the cylinder, and the discharge pipe is installed at the end of the cylinder away from the hot air pipe. The nozzles are located inside the cylinder and close to the discharge pipe. The feed pipe passes through the side wall of the cylinder and connects to the nozzles. When it is necessary to dry materials to obtain powdered dried materials, liquid materials mixed with a liquid medium (such as water) are fed into the feed pipe. The liquid materials are sprayed into the cylinder in a mist form through the nozzles. The hot air pipe sprays hot air to dry the mist-like liquid materials, evaporating the liquid medium. The resulting dried materials are blown into the discharge pipe by the hot air for collection.

[0004] Regarding the aforementioned technologies, the high air velocity of the hot air in the drying chamber may blow some of the not-yet-fully-dried liquid material to the collector, reducing the drying effect on the material. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the drying effect of hot air on materials, this application provides a multi-functional atomizing dryer.

[0006] The multifunctional atomizing dryer provided in this application adopts the following technical solution: A multifunctional atomizing dryer includes a cylinder, a nozzle, a feed pipe, a hot air pipe, and a discharge pipe. The hot air pipe is located at one end of the cylinder, and the discharge pipe is located at the end of the cylinder away from the hot air pipe. The nozzle is located inside the cylinder and close to the discharge pipe. The feed pipe passes through the side wall of the cylinder and is connected to the nozzle. The cylinder contains a rotating basket with multiple holes on its side wall and multiple heat-conducting balls placed inside. The nozzle is located inside the rotating basket. The feed pipe is rotatably connected to the top wall of the rotating basket. One end of the hot air pipe has an intercepting net that extends into the cylinder and passes through the bottom wall of the rotating basket, rotatably connecting to the rotating basket. The rotating basket is equipped with a drive assembly for rotating the basket.

[0007] By adopting the above technical solution, the hot air blown out of the hot air pipe can be fully mixed and contacted with the tiny liquid particles sprayed from the nozzle after entering the rotating basket, thereby improving the drying effect of the hot air on the tiny liquid droplets. Under normal circumstances, the air velocity of the hot air is relatively high, and some of the hot air may be discharged from the discharge pipe without participating in the drying of the tiny liquid droplets, so the hot air may not be fully utilized. The rotating basket can reduce the heat loss when the hot air dries the tiny liquid droplets, further improving the drying effect of the hot air on the tiny liquid droplets.

[0008] Simultaneously, the hot air blown out by the hot air pipe can blow up the heat-conducting balls inside the rotating basket, allowing the heat-conducting balls to fully contact the tiny liquid particles sprayed from the nozzle, causing the tiny liquid particles to adhere to the heat-conducting balls. Since the hot air heats the heat-conducting balls, the heat-conducting balls can also heat and dry the adhered tiny liquid particles. Compared with the direct convection drying method of hot air and tiny liquid particles, the adhesion of tiny liquid particles to the heat-conducting balls increases the drying time of the tiny liquid particles in the hot air, thus improving the drying effect of tiny liquid droplets. The high-speed hot air can cause the heat-conducting balls to collide with the inner wall of the rotating basket, and when the drive component drives the rotating basket to rotate, it can further improve the collision effect between the heat-conducting balls and the inner wall of the rotating basket, so that the material adhering to the heat-conducting balls becomes dust and is then discharged from the holes.

[0009] Optionally, a turbine fan is provided on the top wall of the rotating basket.

[0010] By adopting the above technical solution, the turbofan can generate an upward airflow inside the cylinder, accelerating the flow of gas from the cylinder out of the discharge pipe.

[0011] Optionally, the cylinder includes a cylindrical section, the rotating basket is located in the cylindrical section and is arranged coaxially with the cylindrical section, the rotating basket is frustum-shaped, and the diameter of the top wall of the rotating basket is larger than the diameter of the bottom wall.

[0012] By adopting the above technical solution, the rotating basket is shaped like a frustum, and the diameter of the top wall of the rotating basket is larger than the diameter of the bottom wall. This allows the distance between the side wall of the rotating basket and the side wall of the cylindrical end in the cylinder to gradually decrease. Therefore, the gas flow velocity between the cylinder and the rotating basket will gradually increase due to the decrease in distance, thereby achieving an upward airflow. The gas discharged from the holes can be captured by the turbine fan along with the upward airflow, reducing the amount of material accumulated in the cylinder.

[0013] Optionally, the feed pipe is fitted with a second bearing, the inner ring of the second bearing is connected to the feed pipe, the second bearing is fitted with a sleeve, the sleeve is connected to the outer ring of the second bearing, and at least one of the turbine fan and the rotating basket is coaxially connected to the sleeve.

[0014] By adopting the above technical solution, the inner ring of the second bearing is connected to the feed pipe and the outer ring is connected to the sleeve, which can realize the rotational connection between the turbofan and the feed pipe. Since the turbofan is set on the rotating basket, the second bearing reduces the load on the hot air pipe in the height direction while realizing the rotation of the turbofan, thereby improving the stability and service life of the hot air pipe, and making the turbofan and the rotating basket operate more stably.

[0015] Optionally, the sleeve extends out of the turbofan, and a third bearing is provided on one end of the sleeve extending out of the turbofan. The inner ring of the third bearing is connected to the sleeve. A first support rod and a second support rod are provided on the inner wall of the cylinder. One end of the first support rod is connected to the inner wall of the cylinder, and the other end is connected to the hot air pipe. One end of the second support rod is connected to the inner wall of the cylinder, and the other end is connected to the outer ring of the third bearing.

[0016] By adopting the above technical solution, the first support rod can improve the vertical stability of the hot air pipe and prevent the hot air pipe from shifting after long-term use of the atomizing dryer, thus affecting the operation of the atomizing dryer. The second support rod can transfer part of the load generated by the turbine fan and the rotating basket to the inner wall of the cylinder through the third bearing, thereby further distributing the load borne by the hot air pipe and the second bearing. This prevents the feed pipe and the sleeve from shifting after long-term use of the atomizing dryer, which would cause the hot air pipe and the second bearing to deform and be damaged.

[0017] Optionally, a cleaning assembly is also included, which includes a brush plate and a connecting rod. One end of the connecting rod is connected to the outer wall of the rotating basket, and the other end is connected to the brush plate. The bristles of the brush plate are arranged to fit against the inner wall of the cylinder.

[0018] By adopting the above technical solution, since the brush plate is connected to the outer wall of the rotating basket through the connecting rod, when the drive motor drives the rotating basket to rotate, it can also drive the brush plate to rotate synchronously, brushing and cleaning the inner wall of the cylinder, sweeping off the material attached to the inner wall of the cylinder in the form of dust, and then discharging it from the discharge pipe, thereby reducing material waste and improving the material recovery rate.

[0019] Optionally, the brush plate includes a first brush plate and a second brush plate, which are spaced apart along the inner wall of the cylinder. The first brush plate is provided with a movable rod, one end of which is movably connected to the first brush plate, and the other end is provided with a roller. An elastic element is provided between the roller and the first brush plate. A moving groove for moving the roller is formed on the inner wall of the cylinder, and vibration protrusions are spaced apart on the inner bottom wall of the moving groove.

[0020] By adopting the above technical solution, when the first brush plate rotates, the rollers on the first brush plate can move in the moving groove. When the drive starts at a relatively high speed, since the movable rod is movably mounted on the first brush plate and an elastic element is installed between the rollers and the first brush plate, when the rollers move past the vibrating protrusions in the moving groove, the rollers will cause the inner wall of the cylinder and the rotating basket to vibrate. The vibration of the inner wall of the cylinder can cause the dust-like material adhering to the inner wall of the cylinder that has not been swept by the first and second brush plates to be dispersed in the gas inside the cylinder and then discharged from the discharge pipe. The vibration of the rotating basket can further improve the collision effect between the heat-conducting balls in the rotating basket, thereby accelerating the pulverization of the material adhering to the heat-conducting balls and improving the collection efficiency of the material.

[0021] Optionally, the drive assembly includes a drive motor, a transmission rod, a first bearing, a drive gear, and a driven gear ring. The transmission rod extends through the bottom wall of the cylinder and into the cylinder body. The drive motor is disposed on the bottom wall of the outer side of the cylinder body, and its output shaft is disposed on the end of the transmission rod that protrudes from the cylinder body. The drive gear is disposed on the end of the transmission rod away from the drive motor. The inner ring of the first bearing is sleeved on the outer wall of the hot air pipe, and the outer ring of the first bearing is connected to the lower surface of the rotating basket. The driven gear ring is disposed on the outer peripheral wall of the first bearing. The drive gear and the driven gear ring mesh with each other.

[0022] By adopting the above technical solution, since the inner ring of the first bearing is sleeved on the outer wall of the hot air pipe and the outer ring is connected to the lower surface of the rotating basket, the rotating basket and the hot air pipe can be rotatably connected at the same time, while reducing the friction between the hot air pipe and the rotating basket. This reduces the load on the drive motor when it is running. When the drive motor is started, it can drive the drive gear at the end of the transmission rod to rotate. Since the driven gear ring is provided on the outer peripheral wall of the first bearing, the driven gear ring meshes with the drive gear. Therefore, when the drive gear rotates, it can drive the rotating basket to rotate, thereby amplifying the collision effect of the heat-conducting balls in the rotating basket and further accelerating the pulverization of the material attached to the heat-conducting balls.

[0023] Optionally, the hot air duct is provided with multiple hot air branch pipes, and the hot air duct is connected to the multiple hot air branch pipes, with the air outlets of the multiple hot air branch pipes facing downwards.

[0024] By adopting the above technical solution, multiple hot air branch pipes can blow air into the lower part of the cylinder, which can blow up the dust-like material inside the lower part of the cylinder. Combined with the upward airflow generated by the turbofan, this reduces the material accumulated in the lower part of the cylinder and improves the material recovery rate.

[0025] Optionally, an insulation component for heat preservation of the cylinder is provided on the outside of the cylinder.

[0026] By adopting the above technical solution, the heat insulation component can reduce heat loss inside the cylinder and prevent moisture inside the cylinder from condensing on the cooler side wall of the cylinder, thereby improving the drying effect on the material inside the cylinder.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The hot air blown out of the hot air pipe can be fully mixed and contacted with the tiny liquid particles sprayed from the nozzle after entering the rotating basket, thereby improving the drying effect of the hot air on the tiny liquid droplets. When the hot air in the rotating basket dries the tiny liquid droplets, the heat loss of the hot air can be reduced, further improving the drying effect of the hot air on the tiny liquid droplets. 2. The hot air blown out by the hot air duct can blow up the heat-conducting ball inside the rotating basket, so that the heat-conducting ball can fully contact the tiny liquid particles sprayed from the nozzle, causing the tiny liquid particles to adhere to the heat-conducting ball. Since the hot air heats the heat-conducting ball, the heat-conducting ball can also heat and dry the attached tiny liquid particles. Compared with the drying method of directly using hot air and tiny liquid particles to convect, the adhesion of tiny liquid particles to the heat-conducting ball increases the drying time of tiny liquid particles in the hot air, thus improving the drying effect of tiny liquid droplets. 3. The brush plate is connected to the outer wall of the rotating basket via a connecting rod. When the drive motor drives the rotating basket to rotate, it can also drive the brush plate to rotate synchronously, brushing and cleaning the inner wall of the cylinder. The material attached to the inner wall of the cylinder is swept off in the form of dust and then discharged from the discharge pipe, thereby reducing material waste and improving the material recovery rate.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a multifunctional atomizing dryer. (Refer to...) Figure 1 and Figure 2 The atomizing dryer includes a cylinder 1, a nozzle 11, a feed pipe 12, a hot air pipe 13, and a discharge pipe 14. The hot air pipe 13 is located at one end of the cylinder 1, and the discharge pipe 14 is located at the end of the cylinder 1 away from the hot air pipe 13. The nozzle 11 is located inside the cylinder 1 and close to the discharge pipe 14. The feed pipe 12 passes through the side wall of the cylinder 1 and is connected to the nozzle 11.

[0033] A rotating basket 15 is installed inside the cylinder 1. Multiple holes are opened on the side wall of the rotating basket 15, and multiple heat-conducting balls are placed inside. The nozzle 11 is installed inside the rotating basket 15. The feed pipe 12 is rotatably connected to the top wall of the rotating basket 15. One end of the hot air pipe 13 is equipped with an intercepting net and extends into the cylinder 1. It passes through the bottom wall of the rotating basket 15 and is rotatably connected to the rotating basket 15. The end is covered with an intercepting net. A drive assembly 2 is installed on the rotating basket 15.

[0034] The hot air blown out of the hot air pipe 13 enters the rotating basket 15 and can fully mix and contact with the tiny liquid particles sprayed from the nozzle, thereby improving the drying effect of the hot air on the tiny liquid droplets. Normally, the hot air has a high wind speed, and after drying the tiny liquid droplets, the hot air will be directly discharged from the discharge pipe 14, so the hot air may not be fully utilized. When the hot air in the rotating basket 15 dries the tiny liquid droplets, it can reduce the heat loss of the hot air and further improve the drying effect of the hot air on the tiny liquid droplets.

[0035] Meanwhile, the hot air blown out of the hot air pipe 13 can blow up the heat-conducting ball inside the rotating basket 15, so that the heat-conducting ball can fully contact the tiny liquid particles sprayed from the nozzle, causing the tiny liquid particles to adhere to the heat-conducting ball. Since the hot air heats the heat-conducting ball, the heat-conducting ball can also heat and dry the attached tiny liquid particles. Compared with the drying method of directly using hot air and tiny liquid particles to convect, the adhesion of the tiny liquid particles to the heat-conducting ball increases the drying time of the tiny liquid particles in the hot air, thus improving the drying effect of the tiny liquid droplets.

[0036] High-speed hot air can cause the heat-conducting balls to collide with the inner wall of the rotating basket 15. When the drive component 2 drives the rotating basket 15 to rotate, it can further improve the collision effect between the heat-conducting balls and the inner wall of the rotating basket 15, so that the material attached to the heat-conducting balls becomes dust and is then discharged from the holes.

[0037] In this embodiment, the heat-conducting ball can be an aluminum heat-conducting ball, and the interior of the aluminum heat-conducting ball can be made hollow according to actual needs. The aluminum heat-conducting ball is a preferred embodiment. In other embodiments, the heat-conducting ball can be made of other metal materials, etc. The interception mesh is a steel wire mesh, which is a preferred embodiment. In other embodiments, the interception mesh can be a copper wire mesh, etc.

[0038] To achieve rotation of the rotating basket 15, refer to... Figure 1 and Figure 3 The drive assembly 2 in this application includes a drive motor 21, a transmission rod 22, a first bearing 23, a drive gear 24, and a driven gear ring 25. The transmission rod 22 extends through the bottom wall of the cylinder 1 and into the cylinder 1. The drive motor 21 is fixedly installed on the outer bottom wall of the cylinder 1, and its output shaft is connected to the end of the transmission rod 22 that protrudes from the cylinder 1. The drive gear 24 is welded to the end of the transmission rod 22 that is away from the drive motor 21.

[0039] The inner ring of the first bearing 23 is welded and sleeved on the outer wall of the hot air duct 13, and the outer ring of the first bearing 23 is welded to the lower surface of the rotating basket 15. The driven gear ring 25 is welded and installed on the outer peripheral wall of the first bearing 23, and the driving gear 24 and the driven gear ring 25 mesh with each other. In this embodiment, a stabilizing block 16 is also welded on the inner bottom wall of the cylinder 1. The transmission rod 22 passes through the stabilizing block 16 and is rotatably connected to the stabilizing block 16. The stabilizing block 16 can increase the vertical stability of the transmission rod 22.

[0040] Since the inner ring of the first bearing 23 is sleeved on the outer wall of the hot air pipe 13 and the outer ring is connected to the lower surface of the rotating basket 15, the rotating basket 15 and the hot air pipe 13 can be rotatably connected at the same time, while reducing the friction between the hot air pipe 13 and the rotating basket 15, thereby reducing the load on the drive motor 21 when it is running. When the drive motor 21 is started, the drive motor 21 can drive the drive gear 24 at the end of the transmission rod 22 to rotate.

[0041] Since the driven gear ring 25 is provided on the outer peripheral wall of the first bearing 23, and the driven gear ring 25 meshes with the driving gear 24, the driving gear 24 can drive the rotating basket 15 to rotate when it rotates, thereby amplifying the collision effect of the heat-conducting balls in the rotating basket 15 and further accelerating the pulverization of the material attached to the heat-conducting balls.

[0042] After prolonged use of the atomizing dryer, some material will adhere to the inner wall of cylinder 1. To improve the material recovery rate, refer to... Figure 1 and Figure 4 This application also includes a cleaning component 3, which includes a brush plate 31 and a connecting rod 32. One end of the connecting rod 32 is welded to the outer wall of the rotating basket 15, and the other end is welded to the brush plate 31. The bristles of the brush plate 31 are fitted into the inner wall of the cylinder 1. When the rotating basket 15 rotates, it can drive the brush plate 31 to rotate synchronously, thereby cleaning the inner wall of the cylinder 1. Brush plate 31 may not be able to clean all the material, and some material may remain on the bristles. (Refer to...) Figure 3 and Figure 5 Therefore, there are two types of brush plates 31 in this application, namely a first brush plate 311 and a second brush plate 312. The first brush plate 311 and the second brush plate 312 are arranged at intervals along the inner wall of the cylinder 1. A plurality of movable rods 33 are installed on the first brush plate 311. One end of the movable rod 33 is movably connected to the first brush plate 311. A roller 34 is installed on the end of the movable rod 33 away from the first brush plate 311. An elastic element 35 is installed between the roller 34 and the first brush plate 311. A moving groove 36 is opened on the inner wall of the cylinder 1. A vibration groove is opened at intervals on the inner bottom wall of the moving groove 36.

[0043] When the first brush plate 311 rotates, the roller 34 on the first brush plate 311 can move within the moving groove 36. When the drive starts at a relatively high speed, when the roller 34 moves past the position of the vibrating protrusion 37 in the moving groove 36, the roller 34 will cause the inner wall of the cylinder 1 and the rotating basket 15 to vibrate. The vibration of the inner wall of the cylinder 1 can cause the dust-like material attached to the inner wall of the cylinder 1 that has not been swept by the first brush plate 311 and the second brush plate 312 to be dispersed in the gas inside the cylinder 1 and then discharged from the discharge pipe 14. The vibration of the rotating basket 15 can further improve the collision effect between the heat-conducting balls inside the rotating basket 15, thereby accelerating the pulverization of the material attached to the heat-conducting balls and improving the collection efficiency of the material.

[0044] In this embodiment, there are two first brush plates 311 and two second brush plates 312. Having two first brush plates 311 and two second brush plates 312 is a preferred embodiment. In other embodiments, the number can be any number that can clean the side wall of the cylinder 1 and cause the atomizing dryer to vibrate significantly.

[0045] Relying solely on the air pressure inside cylinder 1 to discharge the powdery material from the discharge pipe 14 is inefficient; therefore, it is necessary to increase the gas flow rate inside cylinder 1, referring to... Figure 1 and Figure 4 Therefore, in this application, a turbofan 4 is fixedly installed on the side of the rotating basket 15 near the discharge pipe 14. When the rotating basket 15 drives the turbofan 4 to rotate, it can generate an upward airflow, thereby accelerating the gas flow rate in the cylinder 1 and preventing the dust-like material from partially settling due to the slow gas flow rate in the cylinder 1.

[0046] The weight of the turbofan 4, the rotating basket 15, and the heat-conducting balls inside the rotating basket 15 may cause structural damage to the first bearing 23. (Refer to...) Figure 2 Therefore, it is necessary to reduce the load on the hot air duct 13 and the first bearing 23. Thus, this application provides a second bearing 6 on the outer sleeve of the feed pipe 12. The inner ring of the second bearing 6 is welded to the feed pipe 12. A sleeve 5 is provided on the outer sleeve of the second bearing 6. The sleeve 5 is welded to the outer ring of the second bearing 6. At least one of the turbine fan 4 and the rotating basket 15 is coaxially welded to the sleeve 5.

[0047] The second bearing 6 enables the rotational connection between the turbofan 4 and the feed pipe 12, and utilizes the feed pipe 12 and the second bearing 6 to share the load borne by the hot air pipe 13 and the first bearing 23. In this embodiment, both the turbofan 4 and the rotating basket 15 are welded to the sleeve 5. Welding both the turbofan 4 and the rotating basket 15 to the sleeve 5 is a preferred embodiment. In other embodiments, the sleeve 5 may be welded to either the turbofan 4 or the rotating basket 15.

[0048] The hot air duct 13 and the feed pipe 12 serve as two support points. After prolonged use of the atomizing dryer, the hot air duct 13 and the feed pipe 12 may deform, thus affecting the normal operation of the atomizing dryer. (Refer to...) Figure 1 and Figure 4 Therefore, the hot air pipe 13 and the feed pipe 12 need to be reinforced. Therefore, this application welds a first support rod 8 and a second support rod 9 to the inner wall of the cylinder 1. The sleeve 5 extends out of the turbine fan 4. A third bearing 7 is installed on one end of the sleeve 5 extending out of the turbine fan 4. The inner ring of the third bearing 7 is fixedly connected to the sleeve 5 by a welding machine. One end of the first support rod 8 is welded to the inner wall of the cylinder 1, and the other end is welded to the hot air pipe 13. One section of the second support rod 9 is welded to the inner wall of the cylinder 1, and the other end is welded to the outer ring of the third bearing 7.

[0049] The first support rod 8 can vertically reinforce the hot air duct 13 to prevent it from tilting. The second support rod 9 and the third bearing 7 can limit the position of the feed pipe 12 inside the cylinder 1 to prevent deformation of the feed pipe 12 due to long-term load. The third bearing 7 and the second support rod 9 can transfer part of the load generated by the turbine fan 4 and the rotating basket 15 to the inner wall of the cylinder 1, thereby reducing the load on the hot air duct 13, the first bearing 23, the feed pipe 12, and the second bearing 6, and improving their service life.

[0050] Furthermore, to ensure the normal operation of the brush plate 31, the distance between the first support rod 8 and the second support rod 9 in this application is greater than the length of the first brush plate 311 and the second brush plate 312. In this embodiment, there are four first support rods 8 and four second support rods 9. Four is a preferred embodiment, but in other embodiments, any number can be used to effectively improve the stability of the hot air pipe 13 and the second bearing 6.

[0051] Because this application uses a hot air pipe 13 extending into the cylinder 1 to provide hot air, some powdery material may accumulate at the bottom of the cylinder 1. (Refer to...) Figure 1 and Figure 4 Therefore, hot air is needed to blow up the material in this part and discharge it from the cylinder 1 in conjunction with the turbofan 4. Thus, multiple hot air branch pipes 131 are welded on this application. The hot air pipe 13 is connected to the multiple hot air branch pipes 131, and the air outlets of the multiple hot air branch pipes 131 are set downwards. The downward setting of the air outlets can effectively blow up the material at the bottom of the cylinder 1 and keep the gas flowing upwards at the bottom of the cylinder 1 at all times, reducing the accumulation of material.

[0052] In this embodiment, there are four hot air branch pipes 131. Four hot air branch pipes 131 are a preferred embodiment. In other embodiments, any number of hot air branch pipes 131 can be used to blow the material at the bottom of the cylinder 1 and to create a stable airflow at the bottom of the cylinder 1.

[0053] To further reduce material movement at the bottom of cylinder 1, refer to... Figure 1 and Figure 4 The cylinder 1 in this application includes a cylindrical section, and a rotating basket 15 is located in the cylindrical section and arranged coaxially with the cylindrical section. The rotating basket 15 is frustum-shaped, and the diameter of the top wall of the rotating basket 15 is larger than the diameter of the bottom wall. The frustum-shaped arrangement of the rotating basket 15 allows the distance between the side wall of the rotating basket 15 and the side wall of the cylinder 1 to gradually decrease. Therefore, the gas flow velocity between the cylinder 1 and the rotating basket 15 will gradually increase due to the decrease in distance, thereby achieving an upward airflow. This allows the gas discharged from the holes to be captured by the turbofan 4 along with the upward airflow, reducing the amount of material accumulated in the cylinder 1. In this embodiment, the rotating basket 15 is frustum-shaped, which is a preferred embodiment. In other embodiments, the rotating basket 15 may be frustum-shaped.

[0054] When the temperature difference between the inside and outside of cylinder 1 is large, water vapor inside cylinder 1 may condense and adhere to the inner wall of cylinder 1, as shown in the reference. Figure 3 Therefore, this application attaches a heat insulation layer 10 to the outside of the cylinder 1. In this embodiment, the heat insulation layer 10 is a high-temperature resistant rubber layer. The high-temperature resistant rubber layer is a preferred embodiment. In the gas embodiment, the heat insulation layer 10 can be a sandwich of heat insulation cotton.

[0055] The implementation principle of a multifunctional atomizing dryer according to an embodiment of this application is as follows: Hot air duct 13 introduces hot air into the rotating basket 15 to heat the rotating basket 15 and the heat-conducting balls inside the rotating basket 15. When the temperature is reached, nozzle 11 sprays liquid material evenly into the rotating basket 15 and onto the heat-conducting balls. The heated heat-conducting balls and the hot air in the rotating basket 15 can dry the liquid material. The heat-conducting balls collide with each other in the rotating basket 15 under the blowing of hot air, thereby pulverizing the material attached to the heat-conducting balls. The drive motor 21 drives the rotating basket 15 to rotate, and the rollers 34 on the first brush plate 311 can intensify the collision force of the heat-conducting balls when they pass the vibration protrusions 37, thereby improving the effect of pulverizing the material.
