Description

Technical Field

[0001] This invention belongs to the technical field of tobacco processing equipment, specifically relating to a cleaning device for the cylinder of a tobacco drying machine and its assembly and cleaning method. Background Technology

[0002] A drum dryer is used to dry tobacco shreds. The inner wall of the drum dryer is equipped with cylindrical stir-frying plates, and the axis of the stir-frying plates coincides with the axis of the drum. Multiple vertical stir-frying plates are arranged around the inner wall of the drum dryer. The drum dryer uses the stir-frying plates and multiple vertical stir-frying plates to ensure that the tobacco shreds are evenly heated and dried as the drum rotates and tumbles. During the contact process between the stir-frying plates and the vertical stir-frying plates and the tobacco shreds, a large amount of tobacco powder and tar will adhere to them. In addition, the feed hood and discharge hood of the drum will also come into contact with the tobacco shreds. Over time, a layer of hardened tobacco grime will form on the stir-frying plates, vertical stir-frying plates, feed hood, and discharge hood. On the one hand, the soot adhering to the drum wall frying plate and the vertical frying plate will cause poor heat dissipation of the drum wall frying plate and the vertical frying plate. If it is not removed in time, it will seriously affect the uniform heating of the drum wall frying plate and the vertical frying plate, thereby reducing the quality of tobacco processing and affecting the quality of subsequent product processing. On the other hand, the soot adhering to the drum wall frying plate, the vertical frying plate, the feeding hood and the discharging hood are at risk of falling off. If the soot falls off and mixes into the tobacco, it will cause a quality accident of tobacco products.

[0003] Currently, the soot on the drum wall frying plates, vertical frying plates, feed hood, and discharge hood of the drum dryer is mainly cleaned manually. This means that after production stops, workers enter the drum and scrub with steel brushes. Sometimes, chemical solvents or sandblasting are used for thorough cleaning. Even so, due to the limitations of the space inside the drum and the structure of the frying plates, there are still dead corners on the soot on the drum wall frying plates, vertical frying plates, feed hood, and discharge hood, making it impossible to clean thoroughly. The soot is difficult to clean. In addition, the soot area on the drum wall frying plates, vertical frying plates, feed hood, and discharge hood is large, and manual cleaning has the disadvantages of low cleaning efficiency, high labor intensity, and high labor costs. Furthermore, chemical solvent descaling will release pollutants, and manual cleaning is constrained by costs and other factors, making it impossible to clean in a timely manner. Moreover, manual cleaning carries the risk of damaging the drum wall frying plates and vertical frying plates, which may lead to the leakage of heating steam inside the drum wall frying plates and vertical frying plates. Summary of the Invention

[0004] In view of the above-mentioned deficiencies of the prior art, the present invention provides a cleaning device for the cylinder of a shredder, as well as an assembly and cleaning method, which can effectively clean the soot on the cylinder wall frying plate and the vertical frying plate on the inner wall of the shredder cylinder, and can also effectively clean the soot on the feed hood and the discharge hood. It has high cleaning efficiency, low labor intensity, and low labor cost for cleaning.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A cleaning device for a filament drying machine includes a traveling base with a steel cable running through it and the device able to travel along the cable. One end of the steel cable is fixedly connected to the feed hood of the machine body, and the other end is fixedly connected to the discharge hood. A support frame is fixed on the traveling base, and an internal gear with its axis coinciding with the axis of the machine body is rotatably connected to the support frame. The internal gear is driven to rotate by a meshing drive gear. A nozzle component is provided on the outer circumference of the internal gear. The nozzle component includes a nozzle, which is connected to a dry ice cleaning machine via a dry ice delivery pipe. The dry ice cleaning machine is used to spray dry ice into the machine body and clean the soot on the drum wall, the vertical roasting plate, the feed hood, and the discharge hood.

[0007] Furthermore, the nozzle component includes a telescopic rotating member, which includes a cylinder and a telescopic rotating rod. The cylinder is fixedly connected to the outer circular surface of the internal gear. The axis of the telescopic rotating rod is located on one of the cross-sections of the cylinder. The telescopic rotating rod can extend and retract along the cylinder and can rotate around its axis. A first rotary motor is fixed to the end of the telescopic rotating rod. The output shaft of the first rotary motor is fixedly connected to one end of the nozzle connecting arm. A second rotary motor is fixed to the other end of the nozzle connecting arm. The output shaft of the second rotary motor is parallel to the conveying shaft of the first rotary motor. A nozzle rotating arm is fixed to the output shaft of the second rotary motor, and a nozzle is fixed on the nozzle rotating arm.

[0008] Furthermore, the dry ice delivery pipe is wound around an electric reel, and the drive source of the walking base is linked to the drive source of the electric reel.

[0009] Furthermore, a camera is fixed on the nozzle rotating arm, and the camera's shooting direction is parallel to the nozzle's spray direction. The camera is used to capture images of the nozzle's spray position. The cleaning device also includes a control system, which includes a controller. The camera is connected to the controller's signal input terminal, and the controller's signal output terminal is connected to the dry ice cleaner. The controller is used to control the dry ice spray flow rate of the dry ice cleaner.

[0010] Furthermore, a third rotary motor is fixed on the walking base, and the drive gear is sleeved and fixed on the output shaft of the third rotary motor.

[0011] Furthermore, the steel cable consists of two parallel cables, which are arranged symmetrically to each other on the left and right sides of the central axis of the traveling base in the direction of travel, and also symmetrically to each other on the left and right sides of the cylinder axis.

[0012] A method for assembling a cleaning device for a wire drying machine cylinder includes the following steps:

[0013] S1. First, assemble the walking base, support frame and internal gear. Then, assemble the walking base with the steel cable. Next, fix one end of the steel cable to the feed hood of the cylinder and the other end to the discharge hood.

[0014] S2. Then, assemble the nozzle component with the internal gear, and connect one end of the dry ice delivery pipe to the dry ice cleaning machine and the other end to the nozzle.

[0015] A method for cleaning the cylinder of a wire drying machine, using the aforementioned wire drying machine cylinder cleaning device, includes the following steps:

[0016] (1) Rotate the telescopic rotating rod by a certain angle so that when the nozzle connecting arm and the nozzle rotating arm rotate, the nozzle orifice axis is always on one of the cross sections of the cylinder.

[0017] (2) The internal gear rotates at a certain angle to rotate the nozzle orifice to align with the area between two vertical frying plates in one group. The dry ice cleaning machine delivers dry ice to the nozzle and, through the combined motion formed by the rotation of the nozzle connecting arm and the nozzle rotating arm, realizes the movement of the nozzle in different positions in the area between the two vertical frying plates, thus completing the cleaning of the soot in the area between the two vertical frying plates.

[0018] (3) The internal gear rotates at a certain angle to rotate the nozzle orifice to align with the area between the two vertical stir-fry plates in the next set, and completes the cleaning of the soot in the area between the two vertical stir-fry plates in that set. This process is repeated to complete the cleaning of soot on the vertical stir-fry plates and the stir-fry plates on the cylinder wall along a certain length of the cylinder axis. Then the traveling base travels a certain distance so that the cleaning device travels the distance of one nozzle spray width along the cylinder axis, and repeats the above cleaning action until the soot on the stir-fry plates on the cylinder wall and the vertical stir-fry plates in the entire cylinder is cleaned.

[0019] Furthermore, it also includes step (4), rotating the telescopic rotating rod at a certain angle to rotate the nozzle axis from the cross-section of the cylinder to the longitudinal section. During the rotation of the telescopic rotating rod, the dry ice cleaning machine delivers dry ice to the nozzle and cleans the soot on the feed hood or discharge hood through the coordinated movement of the internal gear, the nozzle connecting arm and the nozzle rotating arm.

[0020] Furthermore,

[0021] Step (1) specifically involves the telescopic rotating rod initially being in a retracted state and rotating it at a certain angle so that when the nozzle connecting arm and the nozzle rotating arm rotate, the nozzle's nozzle axis is always on one of the cross-sections of the cylinder. The first rotating motor is controlled to drive the nozzle connecting arm to rotate at a certain angle, thereby rotating the nozzle connecting arm to a suitable position. The second rotating motor is then controlled to drive the nozzle rotating arm to rotate at a certain angle, thereby rotating the nozzle rotating arm to a suitable position, and thus rotating the nozzle to a suitable position, ensuring that the nozzle does not interfere with or collide with the vertical stir-frying plate when the internal gear rotates.

[0022] In step (2), the nozzle moves to different positions in the area between the two vertical stir-frying plates through the combined motion formed by the extension of the telescopic rotating rod, the rotation of the nozzle connecting arm and the nozzle rotating arm;

[0023] In step (4), the internal gear, telescopic rotating rod, nozzle connecting arm and nozzle rotating arm coordinate with each other, and the combined motion formed by the extension of the telescopic rotating rod and the rotation of the internal gear, nozzle connecting arm and nozzle rotating arm is used to clean the soot on the feed hood or discharge hood. Before cleaning the feed hood, the walking base moves to a position close to the feed hood, and before cleaning the discharge hood, the walking base moves to a position close to the discharge hood.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] In this invention, the internal gear rotates at a certain angle to align the nozzle orifice with the area between two sets of vertical stir-frying plates. The dry ice cleaning machine sprays dry ice through the nozzle onto the opposite sides between the two sets of vertical stir-frying plates and onto the cylinder wall stir-frying plate between the two sets of vertical stir-frying plates to clean the soot on the opposite sides between the two sets of vertical stir-frying plates and the soot on the cylinder wall stir-frying plate between the two sets of vertical stir-frying plates. Then, the internal gear rotates at a certain angle to align the nozzle orifice with the area between the next set of two vertical stir-frying plates, and the soot cleaning of the area between the two sets of two vertical stir-frying plates is completed. This process is repeated to clean the soot on the vertical stir-frying plates and cylinder wall stir-frying plates around the cylinder along a certain length of the cylinder's axial direction. Then, the traveling base travels a certain distance, and the distance traveled by the traveling base is the axial length covered by the nozzle spray pattern, so that the cleaning device travels the distance of one nozzle spray pattern along the cylinder's axial direction. The above cleaning action is repeated until the soot on the cylinder wall stir-frying plates and vertical stir-frying plates throughout the entire cylinder is cleaned. Before cleaning the feed hood, the traveling base moves to a position close to the feed hood. The dry ice cleaning machine supplies dry ice to the nozzles, and through the cooperation of internal gears and nozzle components, cleans the soot on the feed hood. Similarly, it can clean the soot on the discharge hood. Therefore, this cleaning device can effectively clean the soot on the inner wall of the drying machine's drum and the vertical roasting plate, and can also effectively clean the soot on the feed hood and discharge hood. There is no need for workers to enter the drum for cleaning. It has high cleaning efficiency, low labor intensity, and low labor costs. Moreover, since workers do not need to enter the drum, there is no risk of damaging the vertical roasting plate and drum wall roasting plate and causing leakage of heating steam inside them. Furthermore, the dry ice spray cleaning does not emit pollutants.

[0026] In this invention, when cleaning the vertical stir-frying plate and the cylinder wall stir-frying plate, before the internal gear rotates, the telescopic rotating rod is in a retracted state and rotates at a certain angle so that when the nozzle connecting arm and the nozzle rotating arm rotate, the nozzle's nozzle axis is always on one of the cross-sections of the cylinder. The first rotary motor drives the nozzle connecting arm to rotate at a certain angle to rotate the nozzle connecting arm to a suitable position. The second rotary motor drives the nozzle rotating arm to rotate at a certain angle to rotate the nozzle rotating arm to a suitable position, thereby rotating the nozzle to a suitable position. This ensures that the nozzle does not interfere with or collide with the vertical stir-frying plate when the internal gear rotates. After the internal gear rotates at a certain angle and rotates the nozzle nozzle to align with the area between two sets of vertical stir-frying plates, the combined motion formed by the extension of the telescopic rotating rod and the rotation of the nozzle connecting arm and the nozzle rotating arm enables the nozzle to move to different positions in the area between the two vertical stir-frying plates, ensuring thorough cleaning.

[0027] In this invention, when cleaning the soot on the feed hood or discharge hood, the telescopic rotating rod is rotated at a certain angle to rotate the nozzle axis from the cross-section of the cylinder to the longitudinal section. During the rotation of the telescopic rotating rod, the dry ice cleaning machine supplies dry ice to the nozzle. The internal gear, telescopic rotating rod, nozzle connecting arm, and nozzle rotating arm coordinate with each other. Through the extension of the telescopic rotating rod and the combined motion formed by the rotation of the internal gear, nozzle connecting arm, and nozzle rotating arm, the soot at any position on the feed hood or discharge hood is fully covered and cleaned, ensuring that there are no dead corners in the cleaning.

[0028] In this invention, a camera is also fixed on the nozzle rotating arm. The camera's shooting direction is parallel to the nozzle's spraying direction. The camera is used to capture images of the nozzle's spraying position. The cleaning device also includes a control system, which includes a controller. The camera is connected to the controller's signal input terminal, and the controller's signal output terminal is connected to the dry ice cleaner. Thus, during the dry ice spraying cleaning process, the camera captures images of the nozzle's spraying position in real time and feeds them back to the controller. The controller adjusts the dry ice spraying flow rate of the dry ice cleaner in real time based on the severity of the soot in the feedback images to achieve efficient and precise cleaning.

[0034] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] like Figure 1-4 As shown, a cleaning device for a filament drying machine cylinder 9 is provided. The cylinder 9 of the filament drying machine is supported on rollers 23. The cleaning device includes a traveling base 1, along which a steel cable 2 is threaded and can travel. One end of the steel cable 2 is fixedly connected to the feed hood of the cylinder 9, and the other end is fixedly connected to the discharge hood. A support frame 3 is fixed on the traveling base 1. An internal gear 4 with its axis coinciding with the axis of the cylinder 9 is rotatably connected to the support frame 3 via bearings. The internal gear 4 is driven to rotate by a meshing drive gear 5. A nozzle 6 component is provided on the outer circumference of the internal gear 4. The nozzle 6 component includes a nozzle 6 and is connected to a dry ice cleaning machine 8 via a dry ice conveying pipe 7. The dry ice cleaning machine 8 is used to spray dry ice into the cylinder 9 and clean the soot on the cylinder wall roasting plate 10, the vertical roasting plate 11, the feed hood, and the discharge hood. The technology of the traveling base 1 traveling along the steel cable 2 is prior art and will not be described in detail here.

[0038] By rotating the internal gear 4 at a certain angle, the nozzle 6 is rotated to align with the area between two sets of vertical stir-frying plates 11. The dry ice cleaning machine 8 sprays dry ice through the nozzle 6 onto the opposite sides between the two sets of vertical stir-frying plates 11, and onto the cylinder wall stir-frying plate 10 between the two sets of vertical stir-frying plates 11, to clean the soot on the opposite sides between the two sets of vertical stir-frying plates 11 and the soot on the cylinder wall stir-frying plate 10 between the two sets of vertical stir-frying plates 11. Afterwards, by rotating the internal gear 4 at a certain angle, the nozzle 6 is rotated to align with the lower... The cleaning device first cleans the area between two vertical stir-fry plates 11, completing the cleaning of the soot in that area. This process is repeated until the soot on the vertical stir-fry plates 11 and the cylinder wall stir-fry plates 10 along a certain length of the cylinder 9's axial direction is cleaned. Then, the traveling base 1 travels a certain distance equal to the axial length covered by the nozzle 6's spray pattern, allowing the cleaning device to travel the distance of one nozzle 6's spray pattern along the cylinder 9's axial direction. This cleaning action is repeated until all the soot on the cylinder wall stir-fry plates 10 and vertical stir-fry plates 11 within the entire cylinder 9 is cleaned. Before cleaning the feed hood, the traveling base 1 moves to a position close to the feed hood. The dry ice cleaner 8 delivers dry ice to the nozzle 6, and through the cooperation of the internal gear 4 and the nozzle 6 components, cleans the soot on the feed hood. Similarly, it can clean the soot on the discharge hood.

[0039] Therefore, this cleaning device can effectively clean the soot on the inner wall of the drum of the filth drying machine, on the drum wall frying plate 10 and the vertical frying plate 11, and can also effectively clean the soot on the feed hood and the discharge hood. There is no need for workers to enter the drum 9 for cleaning. The cleaning efficiency is high, the labor intensity is low, and the labor cost of cleaning is low. Moreover, since workers do not need to enter the drum 9, there is no risk of damaging the vertical frying plate 11 and the drum wall frying plate 10 and causing the heating steam inside the vertical frying plate 11 and the drum wall frying plate 10 to leak. Furthermore, the dry ice spray cleaning does not emit pollutants.

[0040] In one embodiment, such as Figure 1-4 As shown, the nozzle assembly includes a telescopic rotating component, which comprises a cylinder 12 and a telescopic rotating rod 13. The cylinder 12 is fixedly connected to the outer circumference of the internal gear 4. The axis of the telescopic rotating rod 13 lies on one of the cross-sections of the cylinder 9. The telescopic rotating rod 13 can extend and retract along the cylinder 12 and can rotate around its axis. A first rotary motor 14 is fixed to the end of the telescopic rotating rod 13. The output shaft of the first rotary motor 14 is fixedly connected to one end of the nozzle connecting arm 15. A second rotary motor 16 is fixed to the other end of the nozzle connecting arm 15. The output shaft of the second rotary motor 16 is parallel to the conveying shaft of the first rotary motor 14. A nozzle rotating arm 17 is fixed to the end of the output shaft of the second rotary motor 16, and a nozzle 6 is fixed on the nozzle rotating arm 17. The telescopic rotating component can be a cylinder with a motor.

[0041] In this way, when cleaning the vertical stir-fry plate 11 and the cylinder wall stir-fry plate 10, before the internal gear 4 rotates, the telescopic rotating rod 13 is in a retracted state and rotates a certain angle so that when the nozzle connecting arm 15 and the nozzle rotating arm 17 rotate, the nozzle axis of the nozzle 6 is always on one of the cross sections of the cylinder 9. The first rotary motor 14 drives the nozzle connecting arm 15 to rotate a certain angle to rotate the nozzle connecting arm 15 to a suitable position. The second rotary motor 16 drives the nozzle rotating arm 17 to rotate a certain angle to rotate the nozzle rotating arm 17 to a suitable position, thereby rotating the nozzle 6 to a suitable position. This ensures that the nozzle 6 does not interfere with or collide with the vertical stir-fry plate 11 when the internal gear 4 rotates. When the internal gear 4 rotates a certain angle and rotates the nozzle 6 to align with the area between two sets of vertical stir-fry plates 11, the nozzle 6 is aligned with the area between them. After the area is filled, the combined motion formed by the extension of the telescopic rotating rod 13 and the rotation of the nozzle connecting arm 15 and the nozzle rotating arm 17 enables the nozzle 6 to move to different positions in the area between the two vertical stir-frying plates 11. Specifically, the nozzle 6 is adjusted to a direction with a large angle to the vertical stir-frying plate 11, and the nozzle 6 is adjusted to a position 50-100mm away from the cleaning surface. Dry ice spray cleaning is performed from the end of one of the vertical stir-frying plates 11 near the axis of the cylinder 9, and then the cleaning continues along the arc-shaped surface of the cylinder wall stir-frying plate 10 between the two vertical stir-frying plates 11. Then, dry ice spray cleaning is performed from the end of the other vertical stir-frying plate 11 near the inner wall of the cylinder 9, and so on. This completes the cleaning of the axial length covered by the nozzle 6 spray pattern in the area between the two vertical stir-frying plates 11, ensuring that there are no dead corners in the cleaning.

[0042] In one embodiment, such as Figure 1 As shown, the dry ice delivery tube 7 is wound around the electric reel 18, and the drive source of the traveling base 1 is linked to the drive source of the electric reel 18. Thus, when the traveling base 1 drives the cleaning device to travel along the axial length of the cylinder 9 by the length of the spray pattern covered by the nozzle 6, the electric reel 18 rotates and releases a certain length of the dry ice delivery tube 7.

[0043] In one embodiment, such as Figure 1-4As shown, a camera 19 is also fixed on the nozzle rotating arm 17. The shooting direction of the camera 19 is parallel to the spraying direction of the nozzle 6. The camera 19 is used to capture images of the spraying position of the nozzle 6. The cleaning device also includes a control system, which includes a controller 20. The camera 19 is connected to the signal input terminal of the controller 20, and the signal output terminal of the controller 20 is connected to the dry ice cleaner 8. The controller 20 is used to control the dry ice spraying flow rate of the dry ice cleaner 8. In this way, during the dry ice spraying cleaning process, the camera 19 captures images of the spraying position of the nozzle 6 in real time and feeds them back to the controller 20. The controller 20 adjusts the dry ice spraying flow rate of the dry ice cleaner 8 in real time according to the severity of the soot in the feedback image to achieve efficient and precise cleaning.

[0044] In one embodiment, such as Figure 1 As shown, a motor bracket 22 is fixed on the walking base 1, and a third rotary motor 21 is fixed on the motor bracket 22. A drive gear 5 is sleeved and fixed on the output shaft of the third rotary motor 21. In this way, the third rotary motor 21 rotates and drives the drive gear 5 to rotate, and the drive gear 5 drives the internal gear 4 to rotate relative to the support frame 3. Among them, the first rotary motor 14, the second rotary motor 16 and the third rotary motor 21 are all servo motors.

[0045] In one embodiment, the electrical cables of the walking base 1, the telescopic rotating component, the first rotating motor 14, the second rotating motor 16, and the third rotating motor 21 are all tied to the dry ice delivery pipe 7 and connected to the controller 20. The drive source of the walking base 1 is controlled to open and close by the controller 20. The telescopic rotating rod 13 of the telescopic rotating component is controlled to extend, retract, and rotate by the controller 20. The first rotating motor 14, the second rotating motor 16, and the third rotating motor 21 are all controlled to open and close by the controller 20.

[0046] In one embodiment, such as Figure 1-4 As shown, there are two steel cables 2, which are parallel to each other. The two steel cables 2 are arranged symmetrically to the left and right of the central axis of the walking base 1 in the walking direction, and are also arranged symmetrically to the left and right of the axis of the cylinder 9.

[0047] A method for assembling a cleaning device for a wire drying machine cylinder includes the following steps:

[0048] S1. First, assemble the walking base 1, support frame 3 and internal gear 4. Then, assemble the walking base 1 with the steel cable 2. Then, fix one end of the steel cable 2 to the feed hood of the cylinder 9 and fix the other end to the discharge hood. After that, assemble the third rotary motor 21, drive gear 5 and internal gear 4, and assemble the third rotary motor 21 with the motor bracket 22.

[0049] S2. Assemble the telescopic rotating component, the first rotary motor 14, the nozzle connecting arm 15, the second rotary motor 16, the nozzle rotating arm 17, the nozzle 6, and the camera 19. Fix the cylinder 12 of the telescopic rotating component to the outer surface of the internal gear 4. Then lay the electrical cables of the walking base 1, the telescopic rotating component, the first rotary motor 14, the second rotary motor 16, and the third rotary motor 21. Tie the electrical cables to the dry ice delivery pipe 7. Then wind the dry ice delivery pipe 7 around the electric reel 18. Connect one end of the dry ice delivery pipe 7 to the dry ice cleaning machine 8 and the other end to the nozzle 6. Connect the electrical cables to the controller 20.

[0050] A method for cleaning the cylinder of a wire drying machine, using the aforementioned wire drying machine cylinder cleaning device, includes the following steps:

[0051] (1) The telescopic rotating rod 13 is initially in a retracted state and rotates at a certain angle so that when the nozzle connecting arm 15 and the nozzle rotating arm 17 rotate, the nozzle orifice axis of the nozzle 6 is always on one of the cross-sections of the cylinder 9, see Figure 1 , 2 And 4, the controller 20 controls the first rotary motor 14 to drive the nozzle connecting arm 15 to rotate a certain angle, and rotates the nozzle connecting arm 15 to a suitable position. The controller 20 controls the second rotary motor 16 to drive the nozzle rotating arm 17 to rotate a certain angle, and rotates the nozzle rotating arm 17 to a suitable position, and then rotates the nozzle 6 to a suitable position, so as to ensure that the nozzle 6 and the vertical stir-fry plate 11 do not interfere or collide when the internal gear 4 rotates.

[0052] (2) The controller 20 controls the third rotary motor 21, which drives the internal gear 4 to rotate at a certain angle via the drive gear 5, so as to rotate the nozzle 6 to align with the area between two vertical frying plates 11. The dry ice cleaning machine 8 is started, and 3mm dry ice particles are delivered to the nozzle 6 at ultra-high speed through the dry ice delivery pipe 7. The combined motion formed by the extension of the telescopic rotating rod 13 and the rotation of the nozzle connecting arm 15 and the nozzle rotating arm 17 realizes the movement of the nozzle 6 in different positions in the area between the two vertical frying plates 11. Specifically, the nozzle 6 is adjusted to align with the vertical frying plates 11. The plate 11 is positioned at a large angle, and the nozzle 6 is adjusted to a distance of 50-100mm from the cleaning surface. Dry ice spraying begins from one end of the vertical stir-frying plate 11 closest to the axis of the cylinder 9, proceeding from near to far. Cleaning then continues along the curved surface of the stir-frying plate 10 on the cylinder wall between the two vertical stir-frying plates 11. Dry ice spraying then begins again from the other end of the vertical stir-frying plate 11 closest to the inner wall of the cylinder 9, proceeding from far to near. This completes the cleaning of the axial length covered by the nozzle 6 spray pattern in the area between the two vertical stir-frying plates 11. The travel path of the nozzle 6 in this area between the two vertical stir-frying plates 11 is shown in [reference needed]. Figure 4The dotted line A in the middle;

[0053] (3) The controller 20 controls the third rotary motor 21. The third rotary motor 21 drives the internal gear 4 to rotate a certain angle through the drive gear 5, so as to rotate the nozzle 6 to align with the area between the next set of two vertical stir-fry plates 11, and complete the cleaning of the soot in the area between the two vertical stir-fry plates 11. This process is repeated to complete the cleaning of soot on the vertical stir-fry plates 11 and the cylinder wall stir-fry plates 10 along a certain length of the cylinder 9 axis. Then, the controller 20 controls the drive source of the walking base 1 to make the walking base 1 travel a certain distance, where the distance traveled by the walking base 1 is the distance of the axial length covered by the nozzle 6 spray pattern, so that the cleaning device travels the distance of one nozzle 6 spray pattern along the cylinder 9 axis, and repeats the above cleaning action until the soot on the cylinder wall stir-fry plates 10 and vertical stir-fry plates 11 in the entire cylinder 9 is cleaned.

[0054] (4) Before cleaning the feed hood, control the drive source of the walking base 1 through the controller 20 to move the walking base 1 to a position close to the feed hood. Then, control the telescopic rotating rod 13 to rotate 90° through the controller 20 to rotate the nozzle axis of the nozzle 6 from the cross-section of the cylinder 9 to the longitudinal section. See Figure 3 During the rotation of the telescopic rotating rod 13, the dry ice cleaning machine 8 delivers dry ice to the nozzle 6 at ultra-high speed. At the same time, the controller 20 controls the third rotating motor 21, the telescopic rotating rod 13, the first rotating motor 14, and the second rotating motor 16 to coordinate the internal gear 4, the telescopic rotating rod 13, the nozzle connecting arm 15, and the nozzle rotating arm 17. The combined motion formed by the extension of the telescopic rotating rod 13 and the rotation of the internal gear 4, the nozzle connecting arm 15, and the nozzle rotating arm 17 cleans the soot on the feed hood. Similarly, before cleaning the discharge hood, the controller 20 controls the drive source of the walking base 1 to move the walking base 1 to a position close to the discharge hood and complete the cleaning of the soot on the discharge hood.

[0055] This invention utilizes environmentally friendly dry ice cleaning technology, which does not release pollutants into the environment during the cleaning process. The working principle involves spraying dry ice at ultra-high speed onto the surfaces of the vertical roasting plate 11 and the cylindrical roasting plate 10 that need cleaning. The dry ice sublimates instantly, generating a micro-explosion impact effect. The soot on the surfaces of the vertical roasting plate 11, the cylindrical roasting plate 10, the feed hood, and the discharge hood contracts upon contact with the dry ice, and simultaneously, under the impact of the high-speed airflow, the soot falls off the surfaces of these components, achieving cleaning. Dry ice cleaning technology is safe, effective, environmentally friendly, and harmless. Dry ice is made from recycled CO2 produced in other industrial processes, making it an environmentally friendly cleaning medium. Furthermore, dry ice is safe and non-toxic, and will not cause toxic side effects to operators. Dry ice cleaning can quickly and efficiently clean the soot on the surfaces of the vertical roasting plate 11, the cylindrical roasting plate 10, the feed hood, and the discharge hood, effectively shortening cleaning time and improving cleaning efficiency.

[0056] In summary, this cleaning device can effectively clean the soot on the inner wall of the drying machine cylinder, including the cylinder wall roasting plate 10 and the vertical roasting plate 11, as well as the soot on the feed hood and discharge hood. It eliminates the need for workers to enter the cylinder 9 for cleaning, resulting in high cleaning efficiency, low labor intensity, and low labor costs. Furthermore, since workers do not need to enter the cylinder 9, there is no risk of damage to the vertical roasting plate 11 and cylinder wall roasting plate 10, leading to steam leakage. This cleaning device can also promptly clean the soot inside the drying machine cylinder. After cleaning the cylinder wall roasting plate 10, vertical roasting plate 11, feed hood, and discharge hood, the heat exchange efficiency of the cylinder wall roasting plate 10 and vertical roasting plate 11 is effectively improved, thereby enhancing the quality of the dried tobacco. Moreover, there is no risk of soot falling off after cleaning, preventing quality accidents caused by soot.

[0057] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
