Description

Technical Field

[0001] This invention belongs to the field of tobacco equipment cleaning technology, and specifically relates to a tobacco processing drum cleaning device. Background Technology

[0002] As a crucial step in modern high-quality tobacco processing, the drum process accurately and quickly increases the moisture content and temperature of tobacco leaves, softening them and maintaining their high quality and flavor. The introduction of drums has played a significant role in automating tobacco rehydration, performing indispensable functions in feeding, rehydration, and discharging. However, during the rehydration process, residual tobacco dust often accumulates inside the drums, easily forming lumps of debris mixed in with the tobacco. If left unchecked, this can lead to mixing of different grades of tobacco, affecting the homogenization of the production process.

[0003] In the tobacco leaf production process, the adhesion of tobacco leaves to the front and rear ends of the drum and the inner wall of the drum is an unavoidable problem in domestic cigarette factories. Existing cleaning systems on the production line cannot thoroughly clean the drums. At the end of the day's production or when switching from a lower-end to a higher-end brand, manual inspection and rinsing are still required inside the drum, resulting in low cleaning efficiency and impacting the overall effective operating rate of the equipment. This also poses safety hazards for cleaning personnel and leads to high labor costs. Therefore, designing a tobacco processing drum cleaning device to improve drum cleaning efficiency, avoid safety hazards for cleaning personnel, and reduce labor costs has become an urgent technical problem for those skilled in the art.

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the present solution will be further described in detail below with reference to specific embodiments.

[0043] like Figures 1 to 9 As shown in the figure, an embodiment of the present invention provides a tobacco processing drum cleaning device 1, which includes a frame, a compressed air ejector assembly 2, a drive assembly 3, and a nozzle assembly 4. The frame is disposed on the outer wall of the drum equipment, and the drive assembly 3 is disposed on the frame. The drive assembly includes a connecting pipe 33 for sliding connection with the frame and a drive mechanism for driving the connecting pipe to slide on the frame. The compressed air ejector assembly is connected to a first end of the connecting pipe, and the nozzle assembly is connected to a second end of the connecting pipe 33. The compressed air ejector assembly is used to supply gas or liquid into the connecting pipe, and the drive mechanism drives the nozzle assembly to enter or exit the drum body by driving the connecting pipe 33 to slide on the frame.

[0044] The tobacco processing drum cleaning device provided in this embodiment of the invention allows for easy cleaning of the drum. When cleaning is required, the drive mechanism operates, causing the connecting pipe to slide on the frame. This allows the nozzle assembly to be placed at any desired cleaning location within the drum. Then, the compressed air ejector assembly supplies gas or liquid into the connecting pipe 33, which is then sprayed onto the inner wall of the drum by the nozzle assembly, blowing away residual tobacco dust and achieving drum cleaning. Therefore, this invention provides a convenient and quick way to clean the drum without requiring cleaning personnel to enter, effectively improving cleaning efficiency, avoiding safety hazards for cleaning personnel, and reducing labor costs.

[0045] Furthermore, the frame includes a first mounting plate 11, a second mounting plate 12 parallel to the first mounting plate, and two connecting shafts 13. The second mounting plate 12 is connected to the outer wall of the roller device, and the first mounting plate 11 is connected to the conveyor 5. The two ends of the connecting shafts 13 are perpendicularly connected to the first mounting plate and the second mounting plate, respectively. The second mounting plate has a through hole for the connecting pipe to pass through, and the connecting pipe 33 is slidably fitted with the through hole. The two connecting shafts are symmetrically arranged on both sides of the connecting pipe, and both sides of the connecting pipe are slidably connected to the two connecting shafts. This design simplifies the frame structure, ensures a secure and reliable frame, facilitates easy installation and disassembly, minimizes space occupation, and enhances environmental adaptability. It is understood that the second mounting plate can be installed on the outer wall of the front end of the roller device. During installation, the installation direction of the frame can be adjusted according to the angle at which the second end of the connecting pipe enters the roller body to avoid interference between the nozzle assembly and the internal components of the roller.

[0046] Specifically, a rectangular sliding frame 34 is provided on at least one side of the first end of the connecting tube 33, and the rectangular sliding frame 34 is sleeved on the connecting shaft 13; rollers 341 are rotatably arranged in the upper and lower parts of the rectangular sliding frame, the two rollers are parallel, and the connecting shaft is clamped between the two rollers. With this scheme, when the driving mechanism moves the connecting tube, both rollers roll on the connecting shaft. Preferably, both sides of the first end of the connecting tube are slidably connected to the two connecting shafts through the above structure; the connecting shaft is a chrome-plated shaft.

[0047] Furthermore, the compressed air ejector assembly includes a venturi tube 24, a tap water supply line 21, a compressed air supply line 22, and a steam supply line 23. One end of the venturi tube 24 is connected to the first end of the connecting pipe, and the tap water supply line, the compressed air supply line, and the steam supply line are respectively connected to the other end of the venturi tube. Each of the tap water supply line, the compressed air supply line, and the steam supply line is equipped with a shut-off valve for controlling the flow of the pipeline and a check valve for preventing backflow. This design allows compressed air, high-pressure steam, and a high-pressure water mist formed by tap water and compressed air to be supplied to the connecting pipe, thereby enabling the device to clean and dry the drum.

[0048] Specifically, the tap water delivery pipeline and the steam delivery pipeline are equipped with ball valves for adjusting the flow rate, and the compressed air delivery pipeline is equipped with a pulse valve for adjusting the flow rate, thereby enabling better control of each delivery pipeline.

[0049] like Figure 3 As shown, the on / off state of the tap water supply pipeline is controlled by the tap water pipeline shut-off valve 271, supplying tap water to the tap water supply pipeline. The tap water flow rate in the tap water supply pipeline is regulated by the tap water pipeline ball valve 281. A tap water pipeline check valve 291 prevents tap water backflow. The tap water supply pipeline 21 is connected to the Venturi tube 24, allowing tap water to mix into the Venturi tube. The on / off state of the compressed air supply pipeline is controlled by the compressed air pipeline shut-off valve 272, supplying compressed air to the compressed air supply pipeline 22. The pressure is regulated by the pulse valve 282. The flow rate of compressed air in the compressed air delivery pipeline is controlled by a one-way valve 292 to prevent backflow of compressed air. The compressed air delivery pipeline 22 is connected to the venturi tube 24 to mix compressed air into the venturi tube. The on / off state of the steam delivery pipeline is controlled by a steam pipeline shut-off valve 273. Steam is supplied to the steam delivery pipeline 23. The flow rate of steam in the steam delivery pipeline is regulated by a steam pipeline ball valve 283. The steam pipeline one-way valve 293 is used to prevent backflow of steam. The steam delivery pipeline 23 is connected to the venturi tube 24 to mix steam into the venturi tube.

[0050] Preferably, the Venturi tube 24 is connected to the first end of the connecting tube 33 via the positioning end body 25 and the actuator mounting body 26.

[0051] It is understandable that the pipeline ejection principle is the same as the ejection principle in the existing technology. Specifically, the Venturi tube is the key device to achieve good mixing of compressed air and tap water. When the compressed air enters the constricted section of the Venturi tube, according to the following formula (1) continuity law, the air velocity increases further, and the water flow of tap water is also accelerated due to the reduction of the cross-section of the Venturi tube.

[0052] A1×V1=A2×V2(1);

[0053] Where A1 is the cross-sectional area of ​​the flared section of the venturi tube, V1 is the velocity of the fluid in the flared section of the venturi tube, A2 is the cross-sectional area of ​​the constricted section of the venturi tube, and V2 is the velocity of the fluid in the constricted section of the venturi tube.

[0054] When the two-phase high-speed fluids, namely tap water and compressed air, enter the flared section, according to Bernoulli's law, the pressure drops sharply, causing air bubbles to form. At this point, according to the momentum theorem, the high-speed airflow transfers momentum to the low-speed water flow, giving the water additional kinetic energy. This momentum transfer process promotes bubble formation and the relative motion of the two-phase fluids. Ultimately, under the combined action of pressure and velocity, sufficient contact and mixing of the gas and liquid are achieved. By adjusting the inlet pressure parameters and geometric parameters, the mixing enhancement effect of the venturi tube can be optimized. It can be seen that after the compressed air flows into the venturi tube at a high velocity from its delivery pipe, it forms a jet, generating entrainment flow, mixing with the tap water, and exchanging momentum. During the flow, the velocity field gradually becomes uniform. The venturi tube is connected to the connecting pipe, and the high-pressure water flow is transmitted through the venturi tube to the connecting pipe and then ejected through the nozzle assembly.

[0055] Preferably, the nozzle assembly 4 is an automatic rotating nozzle.

[0056] like Figure 8 As shown, the nozzle assembly 4 includes a mounting portion 41 connected to the second end of the connecting pipe, and a plurality of nozzles 42 rotatably disposed on the outer circumferential surface of the mounting portion. Each nozzle is connected to the inner cavity of the second end of the connecting pipe through the mounting portion. With this design, under the impact of fluid in the connecting pipe, the nozzles automatically rotate due to the pressure of the fluid impact, while high-pressure fluid is ejected from the nozzles of the nozzles, thus enabling better cleaning of the roller. It can be understood that the nozzle can rotate one full revolution on the mounting portion, i.e., the nozzle is a 360-degree nozzle.

[0057] like Figure 4 and Figure 5As shown, the driving mechanism further includes a rectangular clamping frame 32 and a driving member 31. Clamping wheels 321 are rotatably mounted on both the upper and lower parts of the rectangular clamping frame, with the rotation axes of the two clamping wheels parallel to each other. The connecting pipe 33 is clamped between the two clamping wheels. The driving member is mounted on the rectangular clamping frame and is used to drive the rotation axes 322 of the clamping wheels to rotate. The frame also includes a third mounting plate 14, which is located on both sides of the second mounting plate, respectively. The third mounting plate 14 has a through hole for the connecting pipe to pass through, the through hole being opposite to the via hole and slidingly engaging with the connecting pipe. The third mounting plate is positioned close to the second mounting plate, and the rectangular clamping frame is mounted on the third mounting plate. In this design, during use, the driving component drives the rotating shaft to rotate, causing the clamping wheels to rotate accordingly. The friction between the clamping wheels and the outer wall of the connecting pipe moves the connecting pipe, moving it closer to or away from the first mounting plate. This allows the nozzle assembly to enter or exit the roller body along with the second end of the connecting pipe. It is understood that the connecting pipe also moves the rectangular sliding frame, causing the rollers to roll or slide on the connecting shaft. The compressed air ejector assembly, such as the venturi tube and various delivery pipes, moves with the connecting pipe. In one specific embodiment, the maximum linear movement distance of the connecting pipe can be 6 meters, ensuring it does not interfere with the frame while avoiding deformation due to excessive distance. In this design, two driving components are preferred, each driving one of the two clamping wheels to rotate synchronously.

[0058] Specifically, the driving mechanism further includes an adjusting frame 324 and at least two adjusting bolts 323. The adjusting frame has a U-shaped structure, and the adjusting frame 324 is fitted over the lower end of the rectangular clamping frame 32. The lower part of the rectangular clamping frame has an elongated vertical hole through which the shaft of the clamping wheel passes. The side plate of the adjusting frame is provided with a connecting hole opposite to the elongated vertical hole 326. The bottom plate of the adjusting frame is provided with at least two threaded holes for engaging with the threaded sections of the adjusting bolts 323, and the lower side plate of the rectangular clamping frame is provided with at least two threaded holes 325 for engaging with the threaded sections of the adjusting bolts. Each threaded hole corresponds to each screw hole. With this scheme, by rotating the adjusting bolts, the adjusting frame moves up and down, thereby driving the clamping wheel located in the lower part of the rectangular clamping frame to move closer to or away from the clamping wheel located above it through the shaft located in the connecting hole of the adjusting frame. This allows adjustment of the clamping force of the two clamping wheels on the connecting tube, so as to better drive the connecting tube to move through the clamping wheels. Understandably, the clamping wheel located in the lower part of the rectangular clamping frame rotates in coordination with its pivot, i.e., the pivot does not rotate. When the connecting tube moves, the clamping wheel rotates around its pivot. No driving component is provided to drive the clamping wheel; only a driving component is provided to drive the clamping wheel in the upper part of the rectangular clamping frame. The same structure can also be provided on the rectangular sliding frame to adjust the clamping force of the two rollers on the connecting tube.

[0059] Preferably, the clamping wheel is a rubber wheel; the driving component is a motor. The roller can also be a rubber wheel; the structure of the roller can be the same as that of the clamping wheel; for example... Figure 5 As shown, both the roller and the clamping wheel can be grooved wheels with an arc-shaped groove in the middle.

[0060] The tobacco processing drum cleaning device of the present invention can adjust the working mode according to the working conditions, specifically as follows:

[0061] During the purging phase:

[0062] The compressed air ejector assembly 2 is connected to the tap water, steam, and compressed air in the production site through various shut-off valves and is controlled by the corresponding control circuits.

[0063] When the same brand of product is changed or a high-end brand is replaced with a low-end brand, the shut-off valve on the compressed air delivery pipeline is opened to introduce compressed air. The compressed air is then transmitted to the connecting pipe through the Venturi tube and then sprayed out as high-pressure gas through the nozzle.

[0064] At the same time, according to the preset purging mode, the motor drives the clamping wheel to rotate, so as to drive the connecting pipe to move linearly into the drum body. Then, the nozzle sprays compressed air to clean the inner wall of the drum body, thereby blowing away the tobacco leaves adhering to it.

[0065] At this stage, after one purging, the image detection module can be used to detect whether there are still tobacco leaves adhering to the inner wall of the cylinder. If so, the part of the inner wall of the cylinder with tobacco leaves adhering to it can be purged again.

[0066] During the cleaning phase:

[0067] The compressed air ejector assembly is connected to the tap water, steam, and compressed air in the production site through various shut-off valves and is controlled by the matching control circuit.

[0068] When switching from a high-end product to a low-end product or when production ends, open the shut-off valves on the tap water supply pipeline and the compressed air supply pipeline to introduce compressed air and tap water. The compressed air is then injected through the Venturi tube to pressurize the tap water, which is then sprayed out as a high-pressure water mist through the nozzle.

[0069] Meanwhile, according to the preset cleaning mode, the motor drives the clamping wheel to rotate, thereby driving the connecting pipe to move linearly into the drum body. Then, the nozzle sprays high-pressure water mist to clean the inner wall of the drum body, thereby cleaning away the tobacco leaves adhering to it.

[0070] At this stage, after one cleaning, the image detection module can be used to detect whether there are still tobacco leaves adhering to the inner wall of the cylinder. If so, the part of the inner wall of the cylinder with tobacco leaves adhering to it can be cleaned again.

[0071] During the drying stage:

[0072] The compressed air ejector assembly is connected to the tap water, steam, and compressed air in the production site through various shut-off valves and is controlled by the matching control circuit.

[0073] When the cleaning process is complete, open the shut-off valves on the compressed air delivery line and the steam delivery line to introduce compressed air and steam. The steam is then injected through the venturi tube to pressurize it and then spray high-pressure steam through the nozzle.

[0074] Meanwhile, according to the preset drying mode, the motor drives the clamping wheel to rotate, which drives the connecting pipe to move linearly into the drum. Then, the nozzle sprays high-pressure steam to dry the inner wall of the drum, thus enabling the inner wall of the drum to be dried quickly and improving work efficiency.

[0075] This invention features a compressed air ejector assembly, which is integrated and installed without visible piping on the production site. It can drive high-pressure air for individual injection or drive tap water or steam for ejection, thus replacing a high-pressure water pump and achieving better energy savings. Furthermore, the invention includes a drive assembly with rubber clamping wheels, giving it flexibility. The drive component and the rubber wheel with a central arc-shaped groove drive the connecting pipe, increasing the support contact area between the rubber wheel and the connecting pipe, reducing single-point bending, improving the stability of the connecting pipe, and enhancing the overall stability of the device. Simultaneously, the drive assembly can drive the connecting pipe forward and backward within a certain stroke range. Combined with the frame mounted on the drum equipment, this allows the nozzle assembly to move freely inside the drum without affecting its internal structure or causing dirt accumulation on the nozzle. Moreover, the invention features an automatically rotating nozzle assembly that can spray fluid in different directions as needed. The spray range can cover different areas of the same interface within the drum, and the rotating nozzle can cover the entire three-dimensional space, cleaning the feed end face, etc., achieving a thorough cleaning process without blind spots. This invention has the advantages of being energy-saving and environmentally friendly, having high operational stability, high cleaning efficiency, and good cleaning effect.

It should be noted that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Moreover, after reading the contents of the present invention, those skilled in the art can make various modifications or alterations to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
