Description

Technical Field

[0001] The utility model relates to a tobacco leaf baking room, in particular to an automatic balanced heat tobacco leaf baking room based on clean energy such as water hydrogen fuel. Background Art

[0002] The most important factor affecting the quality of tobacco leaf baking is the baking temperature. Different baking temperatures need to be provided for tobacco leaves at different baking stages. However, the traditional scheme can only control the temperature of the heat source, the position of the heat source, and other factors that affect the temperature. In fact, the temperature control effect on the surface of the tobacco leaves is not precise enough, and it cannot ensure that all tobacco leaves obtain the optimal baking temperature, resulting in low quality of some tobacco leaves.

[0035] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more specific.

[0036] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0037] According to the utility model, an automatic balanced heat tobacco leaf curing room based on water hydrogen fuel clean energy is provided. Figure 1 , Figure 2 and Figure 3 As shown in FIG. , the plant includes a combustion chamber 1 and a baking chamber 2.

[0038] An axial flow fan 3 is arranged above the combustion chamber 1, and the axial flow fan 3 carries the heat generated by the combustion of the fuel in the combustion chamber 1 into the heating pipeline through hot air. The heating pipeline includes a vertically arranged main pipeline 41 and a plurality of horizontally arranged branch pipelines 42 connected to the main pipeline 41. The branch pipelines 42 all pass through the baking chamber 2 to supply heat to the baking chamber 2.

[0039] A multi-layer tobacco leaf support plate 5 is arranged in the baking chamber 2 to support the tobacco leaves to be baked.

[0040] In the present application, the fuel in the combustion chamber 1 is a clean energy fuel, such as alcohol, methane, natural gas, etc., and can also be water hydrogen fuel.

[0041] The axial flow fan 3 can directly introduce the smoke generated by combustion into the heating pipe, especially when the fuel is a clean energy source and the combustion products are pollution-free, the heat products obtained by combustion are directly input into the heating pipe, which can improve the utilization efficiency of heat and reduce energy consumption. When the combustion products may be polluted, air can be introduced from the outside, and the air is heated by the combustion of fuel in the pipeline, thereby bringing the heat produced by combustion into the heating pipe, and also preventing the harmful substances produced by combustion from contaminating the tobacco leaves.

[0042] There are multiple branch pipes 42, and multiple branch pipes 42 connected in parallel are arranged on each plane. Figure 1 Because it is a plan view, only one branch pipeline 42 is shown on one plane. Preferably, a valve is provided on each branch pipeline 42 to control the amount of hot air entering the branch pipeline 42 from the source.

[0043] Preferably, a fan 6 is further provided in the baking chamber 2 to adjust the heat distribution in the baking chamber 2 so that the temperature in each place of the baking chamber 2 is balanced. Specifically, the rotation speed and direction of the fan 6 can be adjusted automatically, so that the air flow speed and flow direction in different areas of the factory building can be controlled as needed, so as to transfer the hotter air to the area where the temperature needs to be increased, and transfer the cooler air to the area where the temperature needs to be reduced.

[0044] Preferably, ventilation holes 7 are provided on the branch pipes 42 to transport the hot air in the branch pipes 42 to the baking chamber 2. A plurality of ventilation holes 7 are provided on each branch pipe 42, and a predetermined spacing is reserved between the ventilation holes 7.

[0045] Preferably, a baffle 8 is provided outside the branch pipe 42 near the vent 7, and the baffle 8 can move horizontally to block the vent 7. The size of the vent 7 blocked is adjusted by controlling the moving position of the baffle 8, thereby adjusting the air output of the vent 7. The area size of the baffle 8 can completely cover one vent 7, so that the vent is closed. Preferably, the side of the branch pipe 42 where the vent is opened is a flat plate, and accordingly, the baffle 8 is also a flat plate, so that the vent 7 can be closed by sticking the flat plates together.

[0046] Preferably, a slide rail is provided on the outer side of the branch pipe 42 , and the baffle 8 slides on the slide rail. The slide rail can not only limit the baffle 8 , but also support and fix the baffle 8 .

[0047] Preferably, the baffles 8 near each vent hole 7 can be controlled independently of each other, so that the hot air supply at various locations in the baking chamber 2 can be set as needed. That is, according to actual needs, the opening size of each vent hole 7 can be different, so as to provide different hot air supply.

[0048] Preferably, a driving connecting rod 9 and a driving motor 10 are provided on the baffle 8, and the horizontal movement direction of the connecting rod 9 is controlled by controlling the motor speed and direction, thereby controlling the reciprocating movement of the baffle 8. A worm is provided on the connecting rod 9, and a turbine is provided on the motor 10, so that the reciprocating movement of the connecting rod is controlled by the rotation of the motor.

[0049] In a preferred embodiment, a temperature sensor is provided on the tobacco leaf support plate 5 . Preferably, a plurality of temperature sensors are provided on each tobacco leaf support plate 5 , with one temperature sensor provided at a certain interval, so as to fully grasp the temperature information at different positions on the tobacco leaf support plate 5 .

[0050] The plant also includes a control system, which can be connected to each temperature sensor and each fan and motor.

[0051] The control system stores the position of each temperature sensor.

[0052] The control system controls the air flow rate of the vent 7 and the rotation speed of the fan 6 according to the temperature information measured by the temperature sensor.

[0053] In the present application, during the process of baking tobacco leaves, as the baking progresses, the optimal temperature required at each moment is different. A temperature one degree lower than the optimal temperature is a low temperature warning value, and a temperature one degree higher than the optimal temperature is a high temperature warning value.

[0054] When the temperature value obtained by a temperature sensor reaches the low temperature warning value, the vent 7 near it opens wider, and the fan blows hot air toward the location of the temperature sensor. When the temperature value obtained by a temperature sensor reaches the high temperature warning value, the vent 7 near it closes smaller, and the fan blows hot air from the location of the temperature sensor to other directions.

[0055] The present invention has been described above in conjunction with preferred embodiments, but these embodiments are only exemplary and serve only as an illustration. On this basis, the present invention may be subjected to a variety of substitutions and improvements, all of which fall within the scope of protection of the present invention.
