Description

Technical Field

[0001] The utility model relates to the technical field of baking furnaces, in particular to a baking furnace with a stable combustion device. Background Art

[0002] A baking furnace (or called baking oven, drying furnace) is a device used for heating, drying or curing materials. It is mainly used in industrial and manufacturing processes to heat materials to a specific temperature to achieve the required physical or chemical properties. The publication number CN2735260Y discloses a hot flue gas baking furnace, which consists of a flue gas generator, an induced draft fan, a control box, etc. The feature is that the outlet of the induced draft fan is connected to one end of the flue gas generator, and an oil inlet pipe, a compressed air pipe and an electronic ignition device are arranged on the closed end. The oil inlet pipe, the air inlet pipe and the electronic ignition device are connected to the control box. The other end of the flue gas generator is connected with an extended conveying pipeline. This utility model uses a hot flue gas baking furnace to replace traditional wood for baking. It not only has a short time and low cost, but also has high baking quality. The hot flue gas baking furnace can dry each part in the furnace simultaneously, with a relatively uniform temperature rise, and the furnace wall after drying has no cracks and does not peel off. However, during the actual working process of this kind of baking furnace, the amount of oxygen entering the combustion chamber and the temperature cannot be controlled, so oxygen injection cannot be carried out as needed, and it is difficult to maintain the stability of the flame, which will cause the flame to fluctuate and go out. And the uncontrollable addition of oxygen may cause the leakage of harmful gases, such as carbon monoxide and nitrogen oxides, so it needs to be improved. Summary of the Utility Model

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a baking furnace machine with a stable combustion device, including a baking furnace machine body 1. An air inlet 2 is provided inside the baking furnace machine body 1. An air inlet cylinder 3 is fixedly installed on the surface of the air inlet 2. A trachea 4 is communicated with the top end of the air inlet cylinder 3. A check valve A5 is arranged on the surface of the trachea 4. A limiting plate 6 is provided inside the air inlet 2. A limiting block 7 is arranged inside the limiting plate 6. A silica gel pad 8 is fixedly installed on the back of the limiting block 7. When the push rod 16 slides inward along the air inlet cylinder 3, it will push the oxygen inside the air inlet cylinder 3. At this time, under the action of pressure, the oxygen will force the soft silica gel pad 8 to deform and generate a gap between it and the limiting plate 6. An installation plate 9 is fixedly installed at the bottom end of the baking furnace machine body 1. A motor 10 is fixedly installed inside the installation plate 9. A gear A11 is fixedly installed at the output end of the motor 10. The gear A11 meshes with a gear B12. The gear B12 is rotatably connected to the bottom end of the baking furnace machine body 1. A rotating plate 13 is fixedly installed at the bottom end of the gear B12. A connecting plate 14 is hinged to the bottom end of the rotating plate 13 through a rotating shaft. Start the motor 10 and drive the gear A11 to rotate. Under the meshing action, it will drive the gear B12 and the rotating plate 13 to rotate. Then, under the action of the connecting plate 14, it will drive the connecting plate 15 and the push rod 16 to slide reciprocally along the air inlet cylinder 3. The connecting plate 14 is hinged to the connecting plate 15 through a rotating shaft. The connecting plate 15 is slidably connected to the air inlet cylinder 3. A push rod 16 is fixedly installed at the top end of the connecting plate 15. The push rod 16 is slidably connected to the air inlet cylinder 3. A sealing ring 17 is arranged inside the push rod 16. During the process of the push rod 16 sliding outward along the air inlet cylinder 3, at this time, under the action of air pressure, the air pressure inside the air inlet cylinder 3 is less than the external air pressure. Immediately, oxygen will be extracted outward through the trachea 4 and the check valve A5. The sealing ring 17 is made of natural rubber. A gas tank 18 is arranged at the bottom end of the baking furnace machine body 1. The gas tank 18 is communicated with the baking furnace machine body 1. A flame monitor 19 is arranged inside the baking furnace machine body 1. A temperature monitor 20 is arranged inside the baking furnace machine body 1.

[0025] Embodiment 2

[0026] Please refer toFigure 2 , 3 , on the side of the baking furnace body 1, a placement plate 21 is fixedly installed. At the top of the placement plate 21, an exhaust fan 22 is fixedly installed. The air extraction end of the exhaust fan 22 is communicated with the baking furnace body 1. The air outlet end of the exhaust fan 22 is communicated with the air collection chamber 24 through a connecting pipe A23. The exhaust fan 22 is started to extract the remaining gas inside. Then the gas will be injected into the air collection chamber 24 through the connecting pipe A23. At the bottom of the baking furnace body 1, an air collection chamber 24 is fixedly installed. The air collection chamber 24 is communicated with the gas tank 18 through a connecting pipe B25. Inside the air collection chamber 24, a connecting pipe A23 is communicated. Inside the air collection chamber 24, a connecting pipe B25 is communicated. A check valve B26 is arranged on the surface of the connecting pipe B25. During the operation of the exhaust fan 22, under the action of air pressure, the gas inside the air collection chamber 24 will be recollected into the gas tank 18 through the check valve B26, avoiding the waste of gas.

[0027] Working principle: Before starting the ignition of the baking furnace body 1, first start the exhaust fan 22 to extract the remaining gas inside. Then the gas will be injected into the air collection chamber 24 through the connecting pipe A23. Then, under the action of air pressure, the gas inside the air collection chamber 24 will be recollected into the gas tank 18 through the check valve B26. Then start the motor 10 to drive the gear A11 to rotate. Under the meshing action, the gear B12 and the rotating plate 13 will be driven to rotate. Then, under the action of the connecting plate 14, the connecting plate 15 and the push rod 16 will be driven to slide reciprocally along the air inlet cylinder 3. During the process of the push rod 16 sliding outward along the air inlet cylinder 3, at this time, under the action of air pressure, the air pressure inside the air inlet cylinder 3 is less than the external air pressure. Immediately, oxygen will be extracted outward through the air pipe 4 and the check valve A5. Then when the push rod 16 slides inward along the air inlet cylinder 3, it will push the oxygen inside the air inlet cylinder 3. At this time, under the action of pressure, the oxygen will force the soft silica gel pad 8 to deform and generate a gap between it and the limiting plate 6, so that oxygen can be injected into the baking furnace body 1 from the inside of the air inlet 2, so that the remaining gas inside the baking furnace body 1 can be replaced, so that the phenomenon of deflagration can be avoided during the ignition process, reducing the safety hazard. During the gas combustion process, at this time, the flame monitor 19 will monitor the combustion fire and ensure that the fire size remains within a suitable range. At the same time, the temperature monitor 20 will also monitor the temperature of the flame. Thus, the input efficiency of oxygen can be controlled by controlling the output frequency of the motor 10, so as to effectively ensure the stability during the gas combustion process, effectively control the generation of harmful gases, and effectively avoid the leakage of harmful gases during the oxygen addition process.

Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
