In the related art, it takes a longer time to swing and dry the materials to achieve an ideal uniformity, with higher energy consumption, resulting in a reduction in the production efficiency of the sterilizing oxygen absorber. Summary of the Invention

[0006] In order to solve the problem that it takes a longer time to swing and dry the materials to achieve an ideal uniformity, with higher energy consumption, resulting in a reduction in the production efficiency of the sterilizing oxygen absorber, this application provides a sterilizing type oxygen absorber drying device.

[0007] The sterilizing type oxygen absorber drying device provided by this application adopts the following technical solutions:

[0008] A sterilizing oxygen absorber drying device, comprising a rotary drum, an oil bath circulation system, a vacuum generating system and a nitrogen supply system. The axis of the rotary drum forms an acute angle with the horizontal plane. The rotary drum includes an inner cylinder and an outer cylinder. The outer cylinder is rotatably connected to a frame body. A drying chamber is formed inside the inner cylinder. A heating chamber for the flow of dielectric oil is formed between the outer cylinder and the inner cylinder. The oil bath circulation system is connected to the heating chamber to drive the circulation of the dielectric oil. The vacuum generating system is connected to the drying chamber to form a vacuum environment. The nitrogen supply system is connected to the drying chamber to introduce nitrogen into the drying chamber. A swing driving assembly connected to the outer cylinder is provided on the frame body, and the swing driving assembly can drive the rotary drum to perform a reciprocating swing motion;

[0009] The inner cylinder is rotatably connected to the outer cylinder. A rotation driving assembly connected to the inner cylinder is provided on the outer cylinder, and the rotation driving assembly can drive the inner cylinder to perform a rotary motion. A first discharge assembly is provided on the inner cylinder, and a second discharge assembly is provided at the lowest position of the outer cylinder. The inner cylinder can rotate the first discharge assembly to the lowest position so that the first discharge assembly and the second discharge assembly are opposite to each other. An opening and closing assembly is provided on the second discharge assembly, and the opening and closing assembly can control the communication between the first discharge assembly and the second discharge assembly so that the material is discharged from the second discharge assembly.

[0010] By adopting the above technical solution, when drying the material (component A or component B), the material is added into the drying chamber, and then the drying chamber is evacuated by the vacuum generating system. The oil bath circulation system introduces high-temperature dielectric oil into the heating chamber to heat the material in the drying chamber. The swing driving assembly drives the rotary drum to swing to perform the drying operation on the material. During the swinging of the rotary drum, the rotation driving assembly drives the inner cylinder to rotate to perform the drying operation on the material. After the material is dried, the vacuum generating system is closed, and the nitrogen supply system fills nitrogen into the drying chamber to make the air pressure in the drying chamber equal to the atmospheric pressure. Then the first discharge assembly and the second discharge assembly are aligned, and then the first discharge assembly and the second discharge assembly are communicated through the opening and closing assembly. The dried material flows out from the second discharge assembly under the action of gravity, completing the discharging of the material. When drying the material, through the combination of rotation and swing, a compound motion is formed, increasing the uniformity of the contact between the material and the inner cylinder, thereby shortening the time for the material to reach the ideal degree, reducing energy consumption, and improving the production efficiency of the sterilizing oxygen absorber.

[0011] Preferably, the rotary axis of the inner cylinder is collinear with the rotation axis, and both ends of the inner cylinder are rotatably connected to the outer cylinder through rotating seats;

[0012] The rotary drive assembly includes a driving motor, a driving gear and a driven gear, wherein the driven gear is coaxially fixed on the inner cylinder, the driving motor is fixed on the outer cylinder, and the driving gear is coaxially fixed on the output shaft of the driving motor and meshes with the driven gear.

[0013] By adopting the above technical solution, when the inner cylinder is rotated, the driving motor drives the inner cylinder to rotate through the meshing of the driving gear and the driven gear, thereby driving the inner cylinder to rotate, and utilizing the gear meshing transmission to improve the transmission accuracy and stability.

[0014] Preferably, the first discharging assembly includes a first discharging barrel and a first sealing plate. The first discharging barrel is fixedly arranged on the outer wall of the inner barrel and is connected to the drying chamber. The first sealing plate can be threadedly connected in the first discharging barrel and can be rotated in or out of the first discharging barrel to close or open the first discharging barrel.

[0015] By adopting the above technical solution, when the material is dried, the sealing plate blocks the first discharge barrel to prevent the outflow of the material, and the inner barrel drives the first discharge barrel to rotate; when the material is dried, the sealing plate is rotated out of the first discharge barrel, so that the first discharge barrel is opened and the material flows out of the inner barrel, making it more convenient to control the discharge of the material.

[0016] Preferably, a sealing gasket is provided on the side of the first sealing plate facing the drying chamber, and the side of the sealing gasket facing away from the first sealing plate is a spherical surface. A sealing ring is provided on the inner wall of the first discharge barrel, and the sealing ring is provided with a spherical surface fitting with the sealing gasket. The first sealing plate can squeeze the sealing gasket to fit with the sealing ring.

[0017] By adopting the above technical solution, when the sealing plate seals the first discharge barrel, the first sealing plate presses the sealing gasket against the sealing ring, and utilizes the spherical contact between the sealing gasket and the sealing ring to increase the sealing area and improve the sealing effect of the sealing plate on the first discharge barrel.

[0018] Preferably, the second discharging assembly includes a second discharging barrel, a second sealing plate and a guide installation mechanism. The second discharging barrel is slidably inserted into the outer barrel and can be opposite to the first discharging barrel. The guide installation mechanism is arranged on the outer barrel and connected to the second discharging barrel to drive the second discharging barrel to dock with the first discharging barrel. The second sealing plate is threadedly connected in the second discharging barrel to be able to seal the second discharging barrel. By adopting the above technical solution, initially, the second plugging plate is located inside the second discharge cylinder, plugging the second discharge cylinder to prevent the medium oil from flowing out. When the material drying is completed and the first discharge cylinder is aligned with the second discharge cylinder, the guiding and installing mechanism drives the second discharge cylinder to dock with the first discharge cylinder, preventing the medium oil from flowing out of the drum through the discharge of the material, effectively avoiding the pollution of the material by the medium oil.

[0019] Preferably, the opening and closing assembly includes a driving ring and a driving rod. The driving ring is slidably sleeved on the second discharge cylinder. A driving seat located inside the second discharge cylinder is fixedly provided on the driving ring. The cross-section of the driving rod is polygonal. The driving rod is fixedly arranged along the axial direction of the second discharge cylinder on the second plugging plate and is slidably inserted into the driving seat, so that the driving ring can drive the driving rod to rotate. A connecting column with a polygonal cross-section is provided on the second plugging plate, and a connecting groove for inserting the connecting column is provided on the first plugging plate. The connecting groove is adapted to the connecting column, so that the second plugging plate can drive the first plugging plate to rotate. The driving rod can drive the first plugging plate and the second plugging plate to rotate into or out of the second discharge cylinder to close or open the second discharge cylinder.

[0020] By adopting the above technical solution, when the first discharge cylinder is docked with the second discharge cylinder, the connecting column is inserted into the connecting groove, and then the driving ring is rotated. The driving ring drives the second plugging plate and the first plugging plate to rotate through the driving rod. The first plugging plate moves down as the plugging plate. When the first plugging plate and the second plugging plate move out of the second discharge cylinder, the second discharge cylinder is opened, and the material discharges from the second discharge cylinder under the action of gravity, improving the convenience of simultaneous opening and closing control of the first discharge cylinder and the second discharge cylinder.

[0021] Preferably, the second discharge cylinder includes a straight cylinder part and an expanding cylinder part. The straight cylinder part is inserted into the expanding cylinder part. Threads are provided on the inner side wall of the straight cylinder part that are threadedly connected to the second plugging plate. A blanking space is formed between the straight cylinder part and the expanding cylinder part. A blanking port communicating with the blanking space is opened on the straight cylinder part, so that the material can flow out along the blanking port and the blanking space.

[0022] By adopting the above technical solution, when the driving rod drives the first plugging plate and the second plugging plate to slide out of the second discharge cylinder, the first plugging plate slides to the blanking port, enabling the material above the first plugging plate to slide into the blanking space through the blanking port, and then the material slides out of the blanking space to achieve the discharge of the material, effectively preventing the second plugging plate from sliding out of the second discharge cylinder and improving the stability of the opening and closing control of the second plugging plate for the second discharge cylinder.

[0023] Preferably, the inner diameter of the first discharge cylinder is smaller than the inner diameter of the second discharge cylinder and smaller than the outer diameter of the first discharge cylinder.

[0024] By adopting the above technical solution, since the diameter of the second plugging plate is larger than that of the first plugging plate, it can effectively avoid the screw engagement between the first plugging plate and the second discharge cylinder when the first plugging plate slides in the second discharge cylinder, thereby improving the convenience of the first plugging plate sliding in the second discharge cylinder.

[0025] Preferably, a first conical surface is provided on one side of the first discharge cylinder facing the second discharge cylinder, and a second conical surface matching the first conical surface is provided at the end of the second discharge cylinder.

[0026] By adopting the above technical solution, when the second discharge cylinder is butted with the first discharge cylinder, by the cooperation of the first conical surface and the second conical surface, the contact area between the first discharge cylinder and the second discharge cylinder can be increased, and the sealing performance of the butt joint between the first discharge cylinder and the second discharge cylinder can be improved.

[0027] Preferably, the second plugging plate includes a connecting portion and a sealing portion. The connecting portion is in threaded connection with the second discharge cylinder. A third conical surface fitting the first conical surface is provided on the sealing portion. When the first conical surface fits the third conical surface, the end face of the sealing portion can fit the end face of the first plugging plate.

[0028] By adopting the above technical solution, when the first discharge cylinder is butted with the second discharge cylinder, while the first conical surface fits the second conical surface, the first conical surface fits the third conical surface, and the end face of the sealing portion fits the end face of the first plugging plate, the dielectric oil between the first plugging plate and the second plugging plate can be extruded, and the pollution of the dielectric oil to the material can be effectively avoided.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. When drying the material, through the combination of rotation and oscillation, a compound motion is formed, increasing the uniformity of the contact between the material and the inner cylinder, thereby shortening the time for the material to reach the ideal degree, reducing energy consumption, and improving the production efficiency of the sterilizing oxygen absorbent;

[0031] 2. When discharging the dried material, rotate the first discharge cylinder to the lowest position, align it with the second discharge cylinder, then drive the second discharge cylinder to be butted with the first discharge cylinder, and then rotate the drive ring. The drive ring drives the first plugging plate and the second plugging plate to rotate and move downward. When the first plugging plate moves downward to the material discharge port, under the action of gravity, the material enters the discharge space along the material discharge port and flows out, completing the discharge of the material, enabling the material to be discharged from the first discharge cylinder at the lowest position under the action of its own gravity, and making the discharge of the material in the drying cavity more thorough;

[0032] 3. When the first discharge cylinder is docked with the second discharge cylinder, while the first conical surface fits with the second conical surface, the first conical surface also fits with the third conical surface, and the end face of the sealing part fits with the end face of the first sealing plate, the dielectric oil between the first sealing plate and the second sealing plate can be extruded, effectively avoiding the pollution of the material by the dielectric oil.

Detailed Description of the Embodiment

[0041] The following further elaborates on this application in conjunction with the appended Figures 1 - 7 drawings.

[0042] An embodiment of this application discloses a sterilizing oxygen absorber drying device.

[0043] The inventors of this application found that when drying the material (component A or component B), the drum only swings reciprocally to shake the material in the drying chamber 24, making it difficult to quickly break up agglomeration and layering. The material takes a longer time to reach the desired uniformity, resulting in higher energy consumption and reduced production efficiency of the sterilizing oxygen absorber. Therefore, this application mainly adopts a design scheme combining rotation and swinging to increase the uniformity of contact between the material and the inner cylinder 21, shorten the time for the material to reach the ideal state, reduce energy consumption, and improve the production efficiency of the sterilizing oxygen absorber.

[0044] Referring to Figure 1 、 Figure 2 and Figure 3 , a sterilizing oxygen absorber drying device includes a drum cylinder 2, an oil bath circulation system 3, a vacuum generation system, and a nitrogen supply system. The axis of the drum cylinder 2 forms an acute angle with the horizontal plane. The drum cylinder 2 includes an inner cylinder 21 and an outer cylinder 22. The outer cylinder 22 is rotatably connected to the frame 1. A rotating shaft 23 is fixedly provided on the outer cylinder 22. The two rotating shafts 23 are arranged oppositely. Each rotating shaft 23 is inserted into the frame 1 on the same side and is rotatably connected.

[0045] Referring to Figure 2 、 Figure 3 , a drying chamber 24 is formed inside the inner cylinder 21, and a heating chamber 25 for the flow of dielectric oil is formed between the outer cylinder 22 and the inner cylinder 21. The oil bath circulation system 3 in this embodiment includes a circulation pipeline 31, an oil tank 32, and an oil pump 33. An oil passage communicating with the heating chamber 25 is provided at the center of each rotating shaft 23. The two ends of the circulation pipeline 31 are respectively connected to the oil passage through a rotary joint. The oil tank 32 is connected in series on the circulation pipeline 31. A certain amount of dielectric oil is stored in the oil tank 32, and the dielectric oil is heated by a self - contained heater. The oil pump 33 is connected in series on the circulation pipeline 31 to pump the dielectric oil in the oil tank 32 into the heating chamber 25. The circulation process of the dielectric oil: The oil pump 33 pumps the heated dielectric oil into the heating chamber 25, and the heat - exchanged dielectric oil flows back into the oil tank through another oil passage, completing the circulating flow of the dielectric oil.

[0046] Referring to Figure 1 , a swing driving assembly 4 for driving the drum cylinder 2 to swing is provided on the frame 1. The swing driving assembly 4 includes a reciprocating swing motor, and the reciprocating swing motor drives the rotating shaft 23 to swing reciprocally through a belt drive structure, thereby realizing the reciprocating swing movement of the drum cylinder 2.

[0047] Referring toFigure 3 , Figure 4 , the rotation axes of the inner cylinder 21 and the outer cylinder 22 are collinear. One end of the inner cylinder 21 is provided with a feed cylinder 211, and the other end is fixedly provided with a rotating shaft. The axes of the rotating shaft and the feed cylinder 211 are collinear with the axis of the inner cylinder 21. The feed cylinder 211 is inserted into the outer cylinder 22 and is rotatably connected to the outer cylinder 22 through a bearing. A rotating seat 212 opposite to the rotating shaft is fixedly provided on the inner side wall of the outer cylinder 22. The rotating shaft is inserted into the rotating seat 212 and rotatably connected, so that the inner cylinder 21 and the outer cylinder 22 are rotatably arranged. A sealing cover 213 is provided at one end of the feed cylinder 211 passing through the outer cylinder 22. The sealing cover 213 is threadedly connected to the feed cylinder 211 to realize the blocking of the feed cylinder 211. A rotary joint 214 is connected and installed on the sealing cover 213. A rubber hose 215 is connected to the rotary joint 214. One end of the rubber hose 215 is respectively connected to the vacuum generating system and the nitrogen supply system through a three-way solenoid valve joint 216. The rubber hose 215 is bent to adapt to the swing of the drum 2. The vacuum generating system forms a vacuum environment in the drying chamber 24 to prevent the materials in the drying chamber 24 from being oxidized during drying. When the drying of the materials is completed, the nitrogen supply system supplies nitrogen into the drying chamber 24, so that the pressure in the drying chamber 24 is equal to the atmospheric pressure, which is convenient for the discharging of the materials.

[0048] Refer to Figure 1 , Figure 5 , a rotation driving assembly 26 for connecting with the inner cylinder 21 is provided on the outer cylinder 22. In this embodiment, the rotation driving assembly 26 includes a driving motor 261, a driving gear 262 and a driven gear 263. The driven gear 263 is coaxially and fixedly arranged on the inner cylinder 21. The driving motor 261 is fixedly arranged on the outer cylinder 22. The driving gear 262 is coaxially and fixedly arranged on the output shaft of the driving motor 261 and meshes with the driven gear 263.

[0049] Refer to Figure 2 , Figure 3 , a first discharging assembly 5 is provided on the inner cylinder 21, and a second discharging assembly 6 is provided at the lowest part of the outer cylinder 22. When discharging materials, the inner cylinder 21 drives the first discharging assembly 5 to rotate to the lowest part, and the first discharging assembly 5 is opposite to the second discharging assembly 6. An opening and closing assembly 7 is provided on the second discharging assembly 6. The opening and closing assembly 7 controls the communication between the first discharging assembly 5 and the second discharging assembly 6, so that the materials are discharged from the second discharging assembly 6.

[0050] When drying the material (component A or component B), the material is added to the drying chamber 24, and then the drying chamber 24 is evacuated through the vacuum generating system. The oil bath circulation system 3 passes the high-temperature medium oil into the heating chamber 25 to heat the material in the drying chamber 24. The reciprocating swing motor drives the drum 2 to swing back and forth through the belt transmission structure to dry the material. During the swinging of the drum 2, the driving motor 261 drives the inner cylinder 21 to rotate to dry the material. Through the combination of rotation and swinging, a composite motion is formed to increase the uniformity of the contact between the material and the inner cylinder 21, thereby shortening the time for the material to reach the ideal level, reducing energy consumption, and improving the production efficiency of the sterilizing oxygen absorber.

[0051] After the material is dried, the vacuum generating system is turned off, and the nitrogen supply system fills nitrogen into the drying chamber 24 so that the air pressure in the drying chamber 24 is equal to the atmospheric pressure. Then, the first discharging assembly 5 is aligned with the second discharging assembly 6, and then the first discharging assembly 5 is connected with the second discharging assembly 6 through the opening and closing assembly 7. The dried material flows out of the second discharging assembly 6 under the action of gravity, completing the unloading of the material.

When the first discharging barrel 51 is at the lowest point, the first discharging barrel 51 is arranged along the vertical direction, and the length of the first discharging barrel 51 is less than the length of the heating chamber 25 in this direction, so as to ensure that the inner barrel 21 rotates in the outer barrel 22. The first blocking plate 52 is adapted to the first discharging barrel 51, and the first blocking plate 52 is inserted in the first discharging barrel 51 and is threadedly connected with the first discharging barrel 51, so that the first blocking plate 52 blocks the opening of the first discharging barrel 51. Prevent medium oil from entering the inner barrel 21 and material from flowing out.

[0053] Reference Figure 3 , Figure 6 A sealing gasket 53 is fixedly arranged on the side of the first blocking plate 52 facing the drying chamber 24. The sealing gasket 53 is made of rubber. The side of the sealing gasket 53 facing away from the first blocking plate 52 is a spherical surface. A sealing ring 54 is fixedly arranged on the inner wall of the first discharging barrel 51. The sealing ring 54 is located on the side of the sealing gasket 53 facing away from the first blocking plate 52. The sealing ring 54 is provided with a spherical surface that fits with the sealing gasket 53. When the first blocking plate 52 blocks the first discharging barrel 51, the sealing gasket 53 is squeezed to fit with the sealing ring 54. By using the spherical contact between the sealing gasket 53 and the sealing ring 54, the sealing fitting area is increased, and the sealing effect of the first blocking plate 52 blocking the first discharging barrel 51 is improved.

[0054] Reference Figure 3 , Figure 6The second discharge assembly 6 includes a second discharge barrel 61, a second blocking plate 62 and a guide installation mechanism 63. The second discharge barrel 61 is slidably inserted into the outer barrel 22 along the vertical direction. When the material is discharged, the inner barrel 21 drives the first discharge barrel 51 to rotate to the lowest point. At this time, the first discharge barrel 51 is opposite to the second discharge barrel 61. The second discharge barrel 61 includes a straight barrel portion 611 and an expanded barrel portion 612. The inner diameter of the expanded barrel portion 612 is larger than the outer diameter of the straight barrel portion 611, so that a material drop space 613 is formed between the straight barrel portion 611 and the expanded barrel portion 612. The expanded tube portion 612 is slidably connected to the outer tube 22. A fixing ring 64 is fixedly provided on the portion of the expanded tube portion 612 located below the outer tube 22. A sealing bellows 65 is sleeved on the expanded tube portion 612. The sealing bellows 65 is located between the fixing ring 64 and the outer tube 22. One end of the sealing bellows 65 is sealed and fixedly connected to the outer tube 22, and the other end is sealed and fixedly connected to the fixing ring 64. The sealing bellows 65 adapts to the sliding of the expanded tube portion 612, so that the expanded tube portion 612 and the outer tube 22 can be sealed. A blanking port 66 is provided on the portion of the straight tube portion 611 located in the blanking space 613, and the blanking port 66 is arranged along the axial direction of the straight tube portion 611.

[0055] Reference Figure 6 , Figure 7 The guide installation mechanism 63 in this embodiment includes a fixed screw 631 and a fixed nut 632. There are two fixed screws 631, which are arranged on both sides of the expansion barrel portion 612. The fixed screw 631 is passed through the fixed ring 64 and is slidably connected with the fixed ring 64. The fixed nut 632 is screwed on the fixed screw 631 and is located on the side of the fixed ring 64 away from the outer barrel 22. When the first discharge barrel 51 is aligned with the second discharge barrel 61, the second discharge barrel 61 is driven to dock with the first discharge barrel 51, and then the fixing nut 632 is screwed to fix the second discharge barrel 61, thereby improving the firmness of the docking between the second discharge barrel 61 and the first discharge barrel 51.

[0056] Reference Figure 6 , Figure 7 The inner diameter of the straight tube 611 is larger than the inner diameter of the first discharge tube 51 and smaller than the outer diameter of the first discharge tube 51. The first discharge tube 51 is provided with a first tapered surface 671 at one end facing the second discharge tube 61, and the straight tube 61 is provided with a second tapered surface 672 at one end facing the first discharge tube 51. When the first discharge tube 51 and the second discharge tube 61 are docked, the second tapered surface 672 abuts against and fits the first tapered surface 671. By using the cooperation of the first tapered surface 671 and the second tapered surface 672, the contact area between the first discharge tube 51 and the second discharge tube 61 can be increased, and the sealing performance of the docking between the first discharge tube 51 and the second discharge tube 61 can be improved.

The connecting part 621 is threadedly connected to the straight cylinder part 611. The thread on the connecting part 621 has the same thread parameters as the thread on the first sealing plate 52 to ensure that the two can rotate simultaneously. The top wall surface of the sealing part 622 is a plane that fits the first sealing plate 52, and the edge of the sealing part 622 is a third conical surface 673 that fits the first conical surface 671.

[0058] Refer to Figure 6 , Figure 7 , in this embodiment, the opening and closing assembly 7 includes a driving ring 71 and a driving rod 72. The bottom end of the expanding cylinder part 612 extends laterally to form a flange.

The connecting groove 76 is adapted to the connecting column 75, so that the second sealing plate 62 drives the first sealing plate 52 to rotate.

[0059] When the first discharge cylinder 51 is docked with the second discharge cylinder 61, drive the second discharge cylinder 61 to move upward so that the second conical surface 672 fits the first conical surface 671. At this time, the connecting column 75 is inserted into the connecting groove 76, and then rotate the driving ring 71. The driving ring 71 drives both the second sealing plate 62 and the first sealing plate 52 to rotate through the driving rod 72. The first sealing plate 52 moves downward along with the second sealing plate 62. When the second sealing plate 62 moves to the material falling opening 66 position, the second discharge cylinder 61 opens, and the material moves along the material falling opening 66 to the material falling space 613 under the action of gravity and discharges from the material falling space 613, improving the convenience of opening both the first discharge cylinder 51 and the second discharge cylinder 61.

[0060] By making the diameter of the second sealing plate 62 larger than that of the first sealing plate 52, it can effectively prevent the thread engagement between the first sealing plate 52 and the second discharge cylinder 61 when the first sealing plate 52 slides in the second discharge cylinder 61, thereby improving the convenience of the first sealing plate 52 sliding in the second discharge cylinder 61.

[0061] The implementation principle of the sterilizing oxygen absorber drying device according to the embodiment of the present application is as follows: when drying the material (component A or component B), the material is added into the drying chamber 24, and then the drying chamber 24 is evacuated by the vacuum generating system. The oil bath circulation system 3 passes the high-temperature dielectric oil into the heating chamber 25 to heat the material in the drying chamber 24. The reciprocating swing motor drives the drum 2 to swing reciprocally through the belt drive structure to perform the drying operation on the material. During the swinging process of the drum 2, the driving motor 261 drives the inner cylinder 21 to rotate to perform the drying operation on the material. Through the combination of rotation and swinging, a compound motion is formed, increasing the uniformity of the contact between the material and the inner cylinder 21, thereby shortening the time for the material to reach the ideal state, reducing energy consumption, and improving the production efficiency of the sterilizing oxygen absorber.

[0062] After the material is dried, the vacuum generating system is turned off, and the nitrogen supply system fills nitrogen into the drying chamber 24 so that the air pressure in the drying chamber 24 is equal to the atmospheric pressure. Align the first discharge cylinder 51 with the second discharge cylinder 61, and then align the first discharge assembly 5 with the second discharge assembly 6. Drive the second discharge cylinder 61 to move upward so that the second conical surface 672 fits with the first conical surface 671. At this time, the connecting column 75 is inserted into the connecting groove 76, and then rotate the driving ring 71. The driving ring 71 drives the second sealing plate 62 and the first sealing plate 52 to rotate through the driving rod 72. The first sealing plate 52 moves downward along with the second sealing plate 62. When the second sealing plate 62 moves to the material falling opening 66 position, the second discharge cylinder 61 opens, and the material moves along the material falling opening 66 to the material falling space 613 under the action of gravity and discharges from the material falling space 613 to complete the discharging of the material.

[0063] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
