Description

Technical Field

[0001] This invention relates to the field of tobacco curing machine technology, and in particular to a tobacco curing machine for promoting continuous and efficient combustion of materials. Background Technology

[0002] A flue-curing barn is a facility or building used to dry tobacco leaves. In tobacco cultivation, flue-curing barns are commonly used to dry harvested tobacco leaves for processing into tobacco products. These facilities are typically equipped with specific control systems to ensure that the temperature and humidity during the drying process are within suitable ranges, thereby preserving the quality and flavor characteristics of the tobacco leaves.

[0003] Tobacco curing barns typically supply heat by burning fuels such as wood, natural gas, or oil. The heat generated from the combustion of these fuels is transferred to the drying chamber of the tobacco leaves through pipes or air circulation systems, thus completing the drying process. Some modern tobacco curing barns may also use electric heating systems to provide heat. The heating methods and equipment vary depending on the specific design and technological level of the tobacco curing barn.

[0004] In summary, the existing devices still have the following technical problems: existing tobacco curing machines require a large amount of burning material to be accumulated before ignition. This method causes the internal temperature of the device to rise sharply, making it impossible to achieve high-efficiency combustion. At the same time, too much material is not completely burned before being cleaned up, which leads to a decrease in the thermal efficiency of material combustion. Therefore, it is necessary to propose a tobacco curing machine that promotes continuous and efficient combustion of materials, and to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Invention

[0005] Based on this, it is necessary to provide a tobacco curing machine for promoting continuous and efficient combustion of materials, addressing the aforementioned technical problems. By setting up a combustion heating mechanism and lowering the ignition angle of the igniter, ignition can be achieved even with a small amount of material to be burned. Simultaneously, the air supply from the circulating fan is delivered from the cavity in the middle of the combustion inner tube and the combustion outer tube through the vent to the middle of the combustion inner tube, which can blow away the ash that has already burned on the surface of the material. At the same time, the pushing inner tube can quantitatively push the burning material into the interior of the combustion inner tube for combustion, thereby effectively improving the combustion efficiency of the material.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The tobacco curing machine provided by this invention promotes continuous and efficient combustion of materials. By setting a combustion heating mechanism, the ignition angle of the igniter is set downward, which can ignite the material even when there is a small amount of material to be burned.

[0018] The tobacco curing machine provided by this invention promotes continuous and efficient combustion of materials. By setting up a material supply mechanism in conjunction with a combustion heating mechanism, the material can be conveyed into the inner part of the outer material pushing tube by a conveying winch. At the same time, a pressure sensor monitors the weight of the material inside the storage box in real time, which can accurately record the amount of mechanical combustion and added material.

[0019] The present invention provides a tobacco curing machine for promoting continuous and efficient combustion of materials. By setting up a PLC controller in conjunction with a temperature sensor and an infrared sensor, the internal structure of the device is closed, which avoids material conveying jams. The infrared sensor can monitor the material falling in real time, while the temperature sensor can monitor the combustion temperature inside the combustion tube. When the temperature is too low, the igniter can be controlled to re-ignite the material inside the combustion tube, thereby effectively reducing the number of ignitions and thus effectively improving the service life of the igniter.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] As described in the background art, existing tobacco curing machines require a large amount of burning material to be accumulated before ignition. This method causes the internal temperature of the device to rise sharply, making it impossible to achieve high-efficiency combustion. At the same time, during combustion, too much material is left unburned and is cleared away, which in turn reduces the thermal efficiency of the material during combustion.

[0033] To address this technical problem, the present invention provides a tobacco curing machine for promoting continuous and efficient combustion of materials, which improves the combustion efficiency of the tobacco curing machine.

[0034] For details, please refer to Figures 1-3 The tobacco curing machine used to promote the continuous and efficient combustion of materials specifically includes a tobacco curing machine support 1, a combustion heating mechanism 2, and a material supply mechanism 3.

[0035] The combustion heating mechanism 2 includes an outer combustion tube 4, an inner combustion tube 5, vents 6, a combustion ventilation component, and a material pushing component. The outer combustion tube 4 is fixedly connected to the surface of the tobacco curing machine bracket 1. The inner combustion tube 5 is fixedly connected to the middle of the outer combustion tube 4. Multiple vents 6 are opened in the middle of the inner combustion tube 5, and ventilation is formed between the middle of the outer combustion tube 4 and the inner combustion tube 5.

[0036] The tobacco curing machine provided by this invention for promoting continuous and efficient combustion of materials, by setting a combustion heating mechanism 2, the ignition angle of the igniter 16 is set downward, which can ignite when there is a small amount of material to be burned. At the same time, in conjunction with the outer pipe air outlet 10, the air outlet connecting pipe 11 and the inner pipe air outlet 15, the air supplied by the circulating fan 8 is delivered from the cavity in the middle of the combustion inner pipe 5 and the combustion outer pipe 4 through the vent hole 6 to the middle of the combustion inner pipe 5, which can blow away the ash that has been burned on the surface of the material. At the same time, in conjunction with the pushing inner pipe 14, the burning material can be quantitatively pushed into the interior of the combustion inner pipe 5 for combustion, thereby effectively improving the combustion efficiency of the material.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] Example 1:

[0039] Please refer to Figures 2-4 A tobacco curing machine for promoting continuous and efficient combustion of materials includes a tobacco curing machine support 1, a combustion heating mechanism 2 and a material supply mechanism 3. The combustion heating mechanism 2 is connected to the middle of the tobacco curing machine support 1, and the material supply mechanism 3 is connected to the upper end of the combustion heating mechanism 2.

[0040] The combustion heating mechanism 2 includes an outer combustion tube 4, an inner combustion tube 5, vents 6, a combustion ventilation component, and a material pushing component. The outer combustion tube 4 is fixedly connected to the surface of the tobacco curing machine bracket 1. The inner combustion tube 5 is fixedly connected to the middle of the outer combustion tube 4. Multiple vents 6 are opened in the middle of the inner combustion tube 5, and ventilation is formed between the middle of the outer combustion tube 4 and the inner combustion tube 5.

[0041] Specifically, the material supply mechanism 3 includes a material conveying pipe 18, a feed pipe 21, a discharge pipe 22, an infrared sensor 23, a conveying assembly, and a material storage assembly. The top surface of the pusher pipe 7 is fixedly connected to the material conveying pipe 18, the upper end of the material conveying pipe 18 is fixedly connected to the feed pipe 21, one end of the material conveying pipe 18 is fixedly connected to the discharge pipe 22, the middle part of the discharge pipe 22 is fixedly connected to the infrared sensor 23, and the end of the discharge pipe 22 away from the material conveying pipe 18 is fixedly connected to the feed inlet 9.

[0042] Specifically, the conveying assembly includes a servo motor 19 and a conveying winch 20. The servo motor 19 is fixedly connected to one end of the material conveying pipe 18 away from the discharge pipe 22. The servo motor 19 is fixedly connected to the top surface of the pusher outer pipe 7. The transmission end of the servo motor 19 is rotatably connected to the conveying winch 20. The conveying winch 20 is rotatably connected to the middle part of the material conveying pipe 18.

[0043] Specifically, the material storage component includes pressure sensors 24 and storage bins 25. Four pressure sensors 24 are fixedly connected to the inner wall of the tobacco curing machine support 1. The upper end of the pressure sensors 24 is fixedly connected to the storage bins 25, and the bottom end of the storage bins 25 is movably inserted into the middle of the feed pipe 21.

[0044] Specifically, the igniter 16 is located below the electric telescopic pump 13, and a certain distance is reserved between the igniter 16 and the inner wall of the combustion inner tube 5. The temperature sensor 17 is located above the electric telescopic pump 13.

[0045] With the above structural design, when the device is in use, the combustible material is first added into the storage tank 25. After the material is stored in the storage tank 25, the pressure sensor 24 senses the amount of combustible material added into the storage tank 25 and transmits the pressure received to the PLC controller 26 in real time. When the material is conveyed, the servo motor 19 is turned on. The servo motor 19 drives the conveying winch 20 to rotate inside the material conveying pipe 18. The rotating conveying winch 20 conveys the combustible material to the side closer to the discharge pipe 22. During the process of the material falling into the discharge pipe 22, the infrared sensor 23 can sense the material falling in real time. If no material falls, the infrared sensor 23 detects no obstruction. At this time, it proves that there is a blockage inside the device, and then manual clearing of the blockage is required.

[0046] Example 2:

[0047] The tobacco curing machine for promoting continuous and efficient combustion of materials provided in Example 1 is further optimized, specifically, as follows: Figures 3-8 As shown, it includes a tobacco curing machine support 1, a combustion heating mechanism 2, and a material supply mechanism 3. The combustion heating mechanism 2 is connected to the middle of the tobacco curing machine support 1, and the material supply mechanism 3 is connected to the upper end of the combustion heating mechanism 2.

[0048] The combustion heating mechanism 2 includes an outer combustion tube 4, an inner combustion tube 5, vents 6, a combustion ventilation component, and a material pushing component. The outer combustion tube 4 is fixedly connected to the surface of the tobacco curing machine bracket 1. The inner combustion tube 5 is fixedly connected to the middle of the outer combustion tube 4. Multiple vents 6 are opened in the middle of the inner combustion tube 5, and ventilation is formed between the middle of the outer combustion tube 4 and the inner combustion tube 5.

[0049] Specifically, the combustion ventilation assembly includes a pusher pipe 7, a circulating fan 8, a feed inlet 9, an outer pipe outlet 10, and an air outlet connecting pipe 11. The pusher pipe 7 is fixedly connected to the middle of the tobacco curing machine bracket 1. The end of the pusher pipe 7 near the combustion inner pipe 5 is fixedly connected to the combustion inner pipe 5. The end of the pusher pipe 7 away from the combustion inner pipe 5 is fixedly connected to the circulating fan 8. The upper surface of the pusher pipe 7 near the combustion inner pipe 5 has a feed inlet 9. The bottom surface of the pusher pipe 7 has an outer pipe outlet 10. The bottom of the outer pipe outlet 10 is fixedly connected to the air outlet connecting pipe 11. The end of the air outlet connecting pipe 11 away from the outer pipe outlet 10 is connected to the chamber in the middle of the combustion outer pipe 4 and the combustion inner pipe 5.

[0050] Specifically, the feeding assembly includes an inner tube support 12, an electric telescopic pump 13, a feeding inner tube 14, an inner tube air outlet 15, an igniter 16, a temperature sensor 17, and a wind speed sensor 27. The inner tube support 12 is fixedly connected to the inner wall of the feeding outer tube 7. The electric telescopic pump 13 is fixedly connected to the surface of the inner tube support 12. The wind speed sensor 27 is fixedly connected to the side of the inner tube support 12 away from the electric telescopic pump 13. The wind speed sensor 27 is located at the air outlet of the circulating fan 8. The feeding inner tube 14 is fixedly connected to the extension end of the electric telescopic pump 13 away from the inner tube support 12. The feeding inner tube 14 is slidably connected to the inner wall of the feeding outer tube 7. The bottom surface of the feeding inner tube 14 has an inner tube air outlet 15. The igniter 16 is fixedly connected to the side of the feeding inner tube 14 connected to the output end of the electric telescopic pump 13. The temperature sensor 17 is fixedly connected to the middle of the tobacco curing machine support 1. The sensing end of the temperature sensor 17 is located in the middle of the combustion inner tube 5.

[0051] Through the above structural design, during initial ignition, the electric telescopic pump 13 is activated, driving the inner pusher tube 14 to move to the side of the inlet 9 away from the combustion inner tube 5. At this time, the inlet 9 is open, and the material falling from the outlet pipe 22 falls to the middle of the outer pusher tube 7. Then, the electric telescopic pump 13 is activated in reverse, pushing the material through the inner pusher tube 14 to push the burning material into the combustion inner tube 5. After the burning material is pushed into the combustion inner tube 5, the airflow from the circulating fan 8 supplies air to the igniter 16. The igniter 16 is activated to ignite the burning material inside the combustion inner tube 5. During the combustion process, the temperature sensor 17 monitors the temperature inside the combustion inner tube 5 in real time. During the combustion process, the electric telescopic pump 13 is activated, driving the inner pusher tube 14 to move away from the combustion inner tube 5. As the circulating fan 8 moves to one side, the air supply from the circulating fan 8 is delivered through the outlet pipe 11 to the cavity formed by the combustion outer pipe 4 and the combustion inner pipe 5 after the inner pipe outlet 15 and the outer pipe outlet 10 intersect. A wind speed sensor 27 is installed at the outlet of the circulating fan 8. The wind speed sensor 27 can monitor the wind pressure output by the circulating fan 8 in real time and transmit the wind speed data to the PLC controller 26 in real time. The PLC controller 26 can adjust the wind pressure in real time. At the same time, the air force can be used to deliver fuel to the combustion outer pipe 4 through the vent holes 6 on the surface of the combustion inner pipe 5 to assist in the combustion of fuel inside the combustion inner pipe 5. The pushing inner pipe 14 continues to move to one side of the circulating fan 8 so that the inner pipe outlet 15 and the outer pipe outlet 10 intersect. When the pushing inner pipe 14... 4. After the end away from the circulating fan 8 moves to the side of the feed inlet 9 away from the outer combustion pipe 4, it automatically closes. At this time, the servo motor 19 automatically starts and drives the conveying winch 20 to rotate. The conveying winch 20 rotates and conveys the combustible material to the discharge pipe 22. During the process of the combustible material falling into the discharge pipe 22, the infrared sensor 23 can monitor the falling material in real time. At the same time, the pressure sensor 24 monitors the amount of material inside the storage box 25 in real time. When the weight decreases to the predetermined value, the servo motor 19 automatically closes. At this time, the electric telescopic pump 13 automatically starts and pushes the combustible material inside the outer pusher pipe 7 into the inner combustion pipe 5 through the inner pusher pipe 14. At the same time, during the movement of the inner pusher pipe 14, the air outlet 10 of the outer pipe and the air outlet 15 of the inner pipe cross again, and the air force is transmitted through the air outlet. After being blown out through pipe 11 and vent 6, the top layer of ash is dispersed, exposing the unburned material at the bottom to the middle of the combustion inner tube 5. Simultaneously, the unburned material re-ignites inside the combustion inner tube 5. If the temperature sensor 17 detects a decrease in the internal temperature of the combustion inner tube 5, the PLC controller 26 controls the igniter 16 to re-ignite the material. This process repeats ten times. Then, the output of the electric telescopic pump 13 continuously pushes the pushing inner tube 14 to one side of the combustion inner tube 5, thus pushing the remaining ash inside the combustion inner tube 5 to the outside. During the movement of the pushing inner tube 14, the air outlet 15 connects to the middle of the combustion inner tube 5, and the air supplied by the circulating fan 8 is directed into the combustion inner tube 5.This allows the residual ash inside the combustion inner tube 5 to be blown outwards.
