Description

Technical Field

[0002] In the tobacco processing industry, when a batch of tobacco leaves is processed, a large amount of moist and sticky tobacco leaves often remain on the inner wall of the drum and in the bottom groove of the tobacco processing equipment. If these residual tobacco leaves are not thoroughly removed, it will lead to serious quality problems such as material mixing and inaccurate process parameters in subsequent batches of tobacco leaves.

[0003] In existing technologies, manual cleaning or high-pressure water washing is commonly used to remove residual tobacco leaves from the drum. Manual cleaning requires operators to enter the drum and scrape off the adhering tobacco leaves with scrapers, which is time-consuming, can easily damage the inner coating of the drum, and poses safety hazards for personnel entering the confined space. High-pressure water washing allows moisture to seep into the transmission mechanism of the tobacco processing equipment, causing corrosion, and requires an additional drying process after washing, making the operation complex and energy-intensive.

[0037] In the tobacco processing industry, when a batch of tobacco leaves is processed, a large amount of moist and sticky tobacco leaves often remain on the inner wall of the drum and in the bottom groove of the tobacco processing equipment. If these residual tobacco leaves are not thoroughly removed, it will lead to serious quality problems such as material mixing and inaccurate process parameters in subsequent batches of tobacco leaves.

[0038] In existing technologies, manual cleaning or high-pressure water washing is commonly used to remove residual tobacco leaves from the drum. Manual cleaning requires operators to enter the drum and scrape off the adhering tobacco leaves with scrapers, which is time-consuming, can easily damage the inner coating of the drum, and poses safety hazards for personnel entering the confined space. High-pressure water washing allows moisture to seep into the transmission mechanism of the tobacco processing equipment, causing corrosion, and requires an additional drying process after washing, making the operation complex and energy-intensive.

[0039] Therefore, to resolve the above issues, please refer to [link / reference needed]. Figure 1 , Figure 2 and Figure 3 This application provides a jet cleaning device 100 for tobacco processing equipment 200. The device uses a nozzle 12 to generate a high-pressure high-speed airflow to peel off the residue accumulated on the deposition area of ​​the inner wall of the processing chamber and blow the peeled residue out of the drum 20, so as to achieve efficient, safe and low-energy cleaning of residual tobacco leaves inside the drum 20 of the tobacco processing equipment 200.

[0040] Specifically, please see Figure 1 and Figure 3 The air jet cleaning device 100 includes a base 10, a connecting member 11, a nozzle 12, and an air path assembly. The base 10 is fitted onto the outer wall of the drum 20 of the tobacco processing equipment 200 along its own rotation axis, and a through-hole communicating with the processing chamber of the drum 20 is provided on the base 10. A first end of the connecting member 11 is sealed and fitted onto the base 10 and communicates with the through-hole. A second end of the connecting member 11, opposite to the first end, extends into the processing chamber of the drum 20. The nozzle 12 is sealed and fitted onto the second end. The air path assembly connects the connecting member 11 to an air source. The nozzle 12 is configured to pressurize and accelerate the airflow, and its nozzle is directed towards the deposition area on the inner wall of the processing chamber.

[0041] Understandably, the gas source delivers pressurized gas to the connecting member 11 via the gas path assembly. After reaching the nozzle 12 through the connecting member 11, the gas increases its pressure and velocity under the action of the flow channel structure inside the nozzle 12, forming a high-pressure, high-speed airflow. The high-pressure, high-speed airflow is ejected from the injection port of the nozzle 12 and acts directly on the deposition area on the inner wall of the processing chamber, using the impact force of the airflow to peel off the residual tobacco leaves accumulated in that area. The peeled tobacco leaf residue moves along the internal space of the processing chamber of the drum 20 under the continuous airflow, and is finally blown out of the drum 20 through its own opening or a pre-set discharge channel, thus completing the cleaning of the residual tobacco leaves inside the drum 20.

[0042] Thus, the jet cleaning device 100 provided in this embodiment utilizes the high-speed airflow generated by the nozzle 12 to efficiently, safely, and with low energy consumption clean the residual tobacco leaves inside the drum 20 of the tobacco processing equipment 200. No operator is required to enter the drum 20, avoiding the safety hazards and damage to the inner wall of the drum 20 caused by manual cleaning. Simultaneously, the jet cleaning device 100 does not involve the use of water during the actual cleaning process, avoiding problems such as rusting of the transmission mechanism due to moisture and the need for additional drying, effectively reducing energy consumption, simplifying the operation process, and significantly improving the efficiency of drum 20 cleaning and the stability of production quality in the tobacco processing process.

[0043] It should be noted that when the drum 20 rotates around its own axis, its two opposite sides along the axis remain fixed, while the circumferential sidewalls of the drum 20 rotate around its central axis. Thus, the deposition area on the inner wall of the processing chamber refers to the lowest point of the circumferential sidewalls of the drum 20 during its rotation around the central axis. Based on the principle of gravity deposition, this location will form a deposition area where residual material naturally accumulates when the drum 20 stops. In this application, when the drum 20 rotates around its central axis, all circumferential sidewalls of the drum 20 rotate to their lowest point and become deposition areas. Since the nozzle 12 is connected to one side of the drum 20 along its own axis, the nozzle 12 can always spray high-pressure, high-speed airflow towards the deposition area. Therefore, the nozzle 12 can effectively clean the entire sidewall of the drum 20.

[0044] In some embodiments, see Figure 1 and Figure 3 The nozzle 12 includes a diffuser section and an acceleration section connected to each other along the direction of the jet flow. The diffuser section and the acceleration section each have interconnected diffuser channels and acceleration channels. The diffuser channel is configured to increase the pressure of the airflow within it. The acceleration channel is configured to increase the velocity of the airflow within it.

[0045] Understandably, the gas from the gas source is input to the connecting member 11 through the gas path assembly, and then flows into the nozzle 12 via the connecting member 11. The airflow entering the nozzle 12 first flows through the diffuser section, where its pressure increases under the action of the diffuser channel to form a high-pressure airflow. Subsequently, the high-pressure airflow after diffusion enters the acceleration section, where its velocity is increased under the action of the acceleration channel to form a high-pressure super-speed airflow that is ejected from the injection port. Thus, through the synergistic effect of the diffuser section and the acceleration section, the nozzle 12 can convert the gas input from the gas source into a high-pressure super-speed airflow with higher kinetic energy, thereby utilizing the high-pressure super-speed airflow to generate a strong impact force on the residual tobacco leaves on the inner wall of the drum 20, effectively improving the stripping effect.

[0046] Specifically, please see Figure 1 and Figure 3 The diffuser channel is constructed in a funnel shape, with the space gradually narrowing along the direction of the jet flow.

[0047] It is understandable that when airflow enters a funnel-shaped, gradually narrowing diffuser, the flow space within the diffuser is compressed as the cross-sectional area decreases, effectively increasing the airflow pressure. Furthermore, by making the diffuser funnel-shaped, the airflow can transition smoothly within the diffuser section, reducing energy loss caused by eddies.

[0048] In some embodiments, see Figure 1 and Figure 3 The acceleration channel is constructed as a Laval tube.

[0049] Understandably, the Laval tube's structural feature is that its flow channel space first contracts and then expands. As the airflow passes through the contraction section, the cross-sectional area gradually decreases, and the airflow velocity continuously increases until it reaches the speed of sound. Upon entering the expansion section, the cross-sectional area gradually increases, and the airflow velocity further exceeds the speed of sound, forming a supersonic airflow. Thus, the supersonic airflow ejected from nozzle 12 possesses extremely high kinetic energy, capable of generating a sufficiently strong impact force on the residual tobacco leaves on the inner wall of drum 20, effectively removing stubborn residues adhering to the inner wall of drum 20. Furthermore, the Laval tube's accelerating flow channel design reduces energy loss during the acceleration process, ensuring the stability and continuity of the high-pressure, supersonic airflow, further improving the cleaning effect.

[0050] In some embodiments, see Figure 1 and Figure 3 The nozzle 12 also includes a flow stabilizing section, which is connected to the end of the acceleration section away from the diffuser section, and a flow stabilizing channel is formed within the flow stabilizing section that communicates with the acceleration channel. The flow stabilizing channel is configured to maintain the flow velocity and pressure of the airflow within it.

[0051] Understandably, after the high-pressure, high-speed airflow is accelerated through the acceleration channel, it enters the stabilizing channel. The stabilizing channel regulates the airflow, reducing turbulence and eddies before injection, allowing the airflow to exit from the nozzle at a more uniform and stable speed and pressure. Thus, by setting a stabilizing section, this application helps ensure a more uniform impact force distribution when the high-pressure, high-speed airflow ejected from nozzle 12 acts on the deposition area on the inner wall of roller 20, avoiding poor cleaning results due to local airflow speed or pressure fluctuations, and ensuring stable operation of the jet cleaning device 100.

[0052] Further, please see Figure 1 and Figure 3 The steady flow channel is constructed as a cylinder extending in the direction of the jet flow.

[0053] Understandably, the cylindrical flow channel structure can provide a stable flow space for airflow, reduce friction and disturbance between the airflow and the channel wall, and thus better maintain the stability of airflow velocity and pressure.

[0054] Furthermore, compared to other flow channel shapes, cylindrical flow channels are simpler to manufacture, which helps reduce production costs. The smoothness of the inner wall of a cylindrical flow channel is also easier to ensure, reducing energy loss during airflow and ensuring that the high-pressure, high-speed airflow is ejected from the nozzle at its optimal state, thus improving the cleaning effect on residual tobacco leaves on the inner wall of the drum 20.

[0055] In some embodiments, see Figure 1 and Figure 3 The supersonic airflow also includes a protective element 13, which is disposed at the nozzle orifice of the nozzle 12 and is configured as a honeycomb structure.

[0056] Understandably, during the cleaning process of the drum 20, when the high-pressure, high-speed airflow is ejected from the nozzle 12, it will peel off and blow out the residual tobacco leaves on the inner wall of the drum 20. During this process, some of the peeled fine tobacco leaf fragments or dust may flow in the opposite direction. If they directly contact the nozzle 12, they can easily enter the flow channel inside the nozzle 12, causing blockage and affecting the normal ejection of subsequent airflow.

[0057] This application utilizes a honeycomb-structured protective component 13. Its dense honeycomb structure physically blocks the reverse-flowing residue, effectively preventing larger particles from entering the nozzle 12. Furthermore, the honeycomb-like perforated structure provides excellent air permeability, allowing high-pressure, high-speed airflow to pass smoothly through the honeycomb holes without significantly reducing the airflow velocity and pressure, thus ensuring the impact force of the airflow on the residual tobacco leaves.

[0058] In addition, the honeycomb structure of the protective component 13 can also straighten the ejected airflow, making the airflow spray more concentrated and stable, which is conducive to further improving the cleaning effect.

[0059] In some embodiments, see Figure 1 and Figure 3 The gas path assembly includes a pipe, a filter, and a switching valve. The outlet end of the pipe is connected to the connecting member 11, and the shortest section of the pipe is connected to the gas source. The filter is fitted to the pipe and is used to filter the airflow passing through the pipe. The switching valve is connected between the pipe and the connecting member 11 and is used to control whether the pipe and the connecting member 11 are connected or disconnected.

[0060] Understandably, the gas output from the gas source first enters the pipe through the inlet end of the pipe. The gas in the pipe flows through the filter element, which can filter out impurities such as moisture, oil, and solid particles contained in the airflow, preventing impurities from entering the nozzle 12 with the airflow and causing blockage or wear of the flow channel, thus ensuring the purity of the airflow to maintain the long-term stable operation of the nozzle 12.

[0061] The filtered clean airflow is delivered to the switch valve through the pipeline. When it is necessary to clean the inside of the drum 20, the switch valve is opened to open the air passage between the pipeline and the connecting part 11. The high-pressure gas can then pass through the connecting part 11 and the flow channels of the nozzle 12 in sequence to form a high-pressure high-speed airflow that is ejected.

[0062] Correspondingly, when the cleaning operation is completed or needs to be paused, the air path between the pipeline and the connecting part 11 can be cut off by closing the switch valve. The operation is convenient and facilitates flexible control of the working status of the jet cleaning device 100.

[0063] Further, please see Figure 1 and Figure 3 The gas circuit assembly also includes a pressure reducing valve, which is connected to the end of the pipeline near the gas source and is used to reduce the pressure of the gas flow in the pipeline.

[0064] It is understandable that the gas output from the gas source usually has a high initial pressure. If it is directly delivered into the pipeline, the pressure may be too high, causing the internal flow channels and intermediate components such as filters to bear excessive load, which will affect the service life of the pipeline and filters.

[0065] This application utilizes a pressure-reducing valve to regulate the high-pressure gas input from the gas source to a set safe pressure range, ensuring a stable and moderate airflow pressure within the pipeline. This prevents damage to equipment components due to excessive pressure and improves the controllability of the airflow pressure.

[0066] In some embodiments, see Figure 1 and Figure 3The jet cleaning device 100 also includes a sealing assembly 14, which includes a seal and a fastener. The seal is sealed between the inner wall of the roller 20 and the connecting member 11, and the fastener is fixed between the seal and the connecting member 11.

[0067] Understandably, the seal effectively fills the gap between the inner wall of the roller 20 and the connecting member 11, preventing airflow leakage from the gap. Fasteners securely fix the seal between the connecting member 11 and the inner wall of the roller 20, preventing the seal from loosening or shifting due to airflow impact or equipment vibration during long-term use, thus avoiding any impact on the sealing effect.

[0068] Specifically, the seal is constructed as a high-temperature fluororubber sealing ring, and the fastener is constructed as a metal spiral wound gasket.

[0069] Understandably, high-temperature fluororubber seals refer to specially formulated "high-temperature fluororubber" (such as peroxide vulcanization systems and perfluoroether rubber FFKM) that can withstand short-term temperatures of 250°C to 300°C. Thus, high-temperature fluororubber seals possess excellent high-temperature resistance, enabling them to adapt to the high-temperature environments that may occur during the production process of tobacco processing equipment 200. This prevents seal aging and failure due to excessively high temperatures, thus ensuring the durability and reliability of the seal.

[0070] The metal spiral wound gasket is made by alternating spiral winding of pre-formed "V"-shaped metal strips and non-metallic filler strips (such as graphite, PTFE, ceramic fiber, etc.). The metal spiral wound gasket has good elasticity and plasticity, and it can be compressed under pressure and rebound when pressure fluctuates, thereby maintaining the effective seal of the high-temperature fluororubber sealing ring on the gap between the inner wall of the roller 20 and the connecting member 11.

[0071] Please see Figure 1 and Figure 2 This application provides a tobacco processing apparatus 200 in one or more embodiments. The tobacco processing apparatus 200 includes an air jet cleaning device 100 and a roller 20 as described in the foregoing embodiments. A processing cavity is formed inside the roller 20. A base 10 is fitted onto the outer wall of the roller 20 of the tobacco processing apparatus 200, and a connecting member 11 and a nozzle 12 extend into the processing cavity.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
