[0048] The present embodiment provides a SIROX temperature and humidity increasing device for increasing the temperature and humidity of tobacco shreds to meet the moisture requirement of the tobacco shred drying process. As shown in Figures 1-6 , the SIROX temperature and humidity increasing device includes a discharge vibrating trough 1000, a heating trough cover plate unit 100, a temperature detection unit, a heating control unit, a central control unit, a power supply protection unit, and a human-computer interaction unit. As shown in Figure 1 , the heating control unit is electrically connected with the heating trough cover plate unit 100, the temperature detection unit is used to detect the temperature of the first steam contact surface 101, and the central control unit is electrically connected with the heating control unit, the temperature detection unit, the power supply protection unit, and the human-computer interaction unit.

[0049] Further, as shown in Figures 2-5 , the discharge vibrating trough 1000 is provided with a discharge channel 1001 for tobacco shred discharge, the heating trough cover plate unit 100 is installed on the top of the discharge vibrating trough 1000, the bottom surface of the heating trough cover plate unit 100 is located on the top of the discharge channel 1001, the bottom surface of the heating trough cover plate unit 100 is provided as the first steam contact surface 101, the heating trough cover plate unit 100 can heat the first steam contact surface 101 to a preset temperature, and the heating control unit is used to adjust the heating power of the heating trough cover plate unit 100. The central control unit can adjust the control signal output by the heating control unit to the heating trough cover plate unit 100 according to the measured temperature of the temperature detection unit, so as to adjust the heating power of the heating trough cover plate unit 100.

[0050] Specifically, the SIROX temperature and humidity increasing device provided in the embodiment increases the temperature of the first steam contact surface 101 and maintains the temperature at a preset temperature, prevents the water vapor blown along the discharge channel 1001 of the discharge vibrating trough 1000 from being liquefied on the first steam contact surface 101, avoids the generation of condensed water on the top of the discharge channel 1001, and further avoids the condensed water from mixing with the cut tobacco in the discharge vibrating trough 1000 under the action of gravity to form a wet mass, thereby ensuring the normal flow of the airflow and the cut tobacco, avoiding the formation of yellow spot tobacco, ensuring the product quality, reducing downtime and labor consumption, and reducing the production cost.

[0051] For example, the heating groove cover plate unit 100 is provided with a plurality of heating groove cover plate units 100 along the discharge direction of the discharge vibrating trough 1000. The discharge vibrating trough 1000 is sequentially provided with a discharging area 1100, an intermediate area 1200 and a discharge area 1300. At least one heating groove cover plate unit 100 is arranged in each of the discharging area 1100, the intermediate area 1200 and the discharge area 1300. The heating power and the preset temperature value of each heating groove cover plate unit 100 can be independently adjusted to cope with different areas in the discharge vibrating trough 1000, the difficulty of temperature maintenance and the concentration of water vapor.

[0052] The preset temperature of the heating groove cover plate unit 100 in the discharging area 1100 is a first temperature value, the preset temperature of the heating groove cover plate unit 100 in the intermediate area 1200 is a second temperature value, and the preset temperature of the heating groove cover plate unit 100 in the discharge area 1300 is a third temperature value. The first temperature value and / or the third temperature value is higher than the second temperature value. In the embodiment, the first temperature value and the third temperature value are both higher than the second temperature value. The reason is that, on the one hand, the closer to the outlet end of the discharge vibrating trough, the higher the difficulty of temperature maintenance, so the heating power and the preset temperature value of the heating groove cover plate unit 100 in the discharge area are moderately increased. On the other hand, the closer to the inlet end of the discharge vibrating trough, the more concentrated the water vapor, so the heating power and the preset temperature value of the heating groove cover plate unit 100 in the discharging area are also moderately increased.

[0053] For example, the preset temperature value of the heating groove cover plate unit 100 can be selected from 75℃-105℃, and preferably 80℃, 85℃, 90℃, 95℃, 100℃, 105℃. In the embodiment, the first temperature value and the third temperature value are both 105℃, and the second temperature value is 100℃.

[0054] Exemplarily, the temperature detecting units are provided in plurality, and each heat groove cover plate unit 100 is provided in correspondence with at least two temperature detecting units. Specifically, the temperature detecting units are arranged in a redundant manner to prevent the temperature detecting units from failing and causing the heat groove cover plate unit 100 to heat abnormally, thereby improving the reliability.

[0055] In the present embodiment, each heat groove cover plate unit 100 is provided in correspondence with three temperature detecting units.

[0056] Exemplarily, the temperature detecting units comprise PT100 thermal resistance temperature sensors, which are accurate and efficient. In other embodiments of the present application, the temperature detecting units can also detect the temperature of the first steam contact surface 101 by using other types of temperature sensors such as thermocouple sensors, thermistor sensors, etc.

[0057] Exemplarily, as shown in Figures 4-6 The heat groove cover plate unit 100 comprises a cover plate body 1, a heating element 2, and a pressing plate 3. The cover plate body 1 is internally provided with a heating cavity 11, the upper end of the heating cavity 11 is provided with an opening, the cover plate body 1 is made of a good thermal conductor material, and the bottom surface of the cover plate body 1 is provided as the first steam contact surface 101; the heating element 2 is installed in the heating cavity 11, the heating element 2 is used to heat the cover plate body 1, and the heating element 2 is electrically connected with the heating control unit; the pressing plate 3 is sealingly installed on the upper surface of the cover plate body 1, and the pressing plate 3 can seal the opening.

[0058] Specifically, the cover plate body 1 of the heat groove cover plate unit 100 can efficiently conduct heat, and the heating element 2 is sealingly installed in the heating cavity 11 of the cover plate body 1 through the pressing plate 3. When working, the heating element 2 rapidly heats the cover plate body 1, so that the temperature of the cover plate body 1 is raised to a preset temperature, preventing the water vapor blown out of the discharge vibrating chute 1000 from being liquefied below the cover plate body 1, avoiding the formation of condensed water on the lower surface of the cover plate body 1, and further avoiding the condensed water from mixing with the cut tobacco in the discharge vibrating chute 1000 under the action of gravity to form a wet mass.

[0059] Exemplarily, as shown in Figure 5 and Figure 6 The heat groove cover plate unit 100 further comprises a heat preservation layer 4, which is arranged between the heating element 2 and the pressing plate 3. The heat preservation layer 4 can hinder the heating element 2 from transferring heat to the pressing plate 3, so that the heat generated by the heating element 2 is concentrated to be transferred downward to the cover plate body 1, thereby improving the heating efficiency of the heating element 2.

[0060] Exemplarily, the heat preservation layer 4 is made of aluminum silicate heat preservation cotton, which has the advantages of good heat insulation performance, high temperature resistance, light weight, good stability, environmental protection, etc. Of course, in other embodiments of the present application, the heat preservation layer 4 can also be made of other heat insulation materials such as mineral wool board, rock wool board, glass fiber cotton board, etc.

[0061] Exemplarily, the heating element 2 adopts a track-type heating blanket, which has the advantages of foldability and long service life. The track-type heating blanket in the embodiment adopts the prior art, which mainly comprises a heating sheet, a controller, a power cord and an outer cover, and the specific structure is well known, which will not be described here.

[0062] Of course, in other embodiments of the present application, the heating element 2 can also adopt other heating elements such as graphene heating sheet and electric heating wire.

[0063] Exemplarily, the cover body 1 is made of stainless steel, preferably a 1.2 mm thick 304 stainless steel plate, which has good heat conduction performance and excellent corrosion resistance. Of course, in other embodiments of the present application, the cover body 1 can also be made of copper alloy, etc.

[0064] Exemplarily, the pressing plate 3 is made of stainless steel, preferably a 2 mm thick 304 stainless steel plate, which has excellent corrosion resistance. Of course, in other embodiments of the present application, the cover body 1 can also be made of copper alloy, etc.

[0065] Exemplarily, as shown in Figure 5 and Figure 6 , the heating groove cover plate unit 100 further comprises a first sealing ring 5, which is fixed to the upper surface of the cover body 1 and is arranged around the peripheral portion of the opening. The first sealing ring 5 is used to block the gap between the cover body 1 and the pressing plate 3. Specifically, the peripheral portion of the pressing plate 3 is provided with a folded portion 31, which is bent downward and wraps the first sealing ring 5 and the cover body 1 on the inner side. The folded portion 31 can play a role of shielding the first sealing ring 5 from the outside, thereby improving the service life of the first sealing ring 5.

[0066] Exemplarily, as shown in Figures 4-6 , the heating groove cover plate unit 100 further comprises a mounting pad 7, a second sealing ring 6 and a locking buckle 8. The mounting pad 7 is arranged around the peripheral portion of the cover body 1. The peripheral portion of the cover body 1 is provided with a sealing flange 13, the lower side of which is provided with a sealing groove 12. The second sealing ring 6 is fixed in the sealing groove 12 and is arranged around the peripheral portion of the cover body 1. The second sealing ring 6 can press against the upper surface of the mounting pad 7 to block the gap between the cover body 1 and the mounting pad 7. The sealing flange 13 can play a role of shielding the second sealing ring 6 from the outside, thereby improving the service life of the second sealing ring 6. The locking buckle 8 is installed on the mounting pad 7 and can press against the upper surface of the pressing plate 3 to press the cover body 1 tightly against the mounting pad 7. The locking buckle 8 adopts the prior art quick buckle, one end of which is rotatably connected to the mounting pad 7, and the other end can selectively press against the upper surface of the pressing plate 3 to lock the pressing plate 3 and the cover body 1. The specific structure of the locking buckle 8 is well known and will not be described here.

[0067] Specifically, the cover plate body 1 is installed on the top of the discharge vibration trough 1000 via the mounting pad 7. The gap between the cover plate body 1 and the mounting pad 7 is the gap between the cover plate body 1 and the discharge channel 1001 of the discharge vibration trough 1000. The second sealing ring 6 can prevent the tobacco and water vapor in the discharge vibration trough 1000 from leaking out through this gap. It can also prevent the leaked water vapor from condensing on the outside of the discharge vibration trough 1000 and then flowing back into the discharge vibration trough 1000 through the gap between the cover plate body 1 and the mounting pad 7, thereby further ensuring product quality.

[0068] For example, such as Figure 5 As shown, the mounting plate 7 is a hollow structure, filled with thermal insulation material to improve its thermal insulation performance. The mounting plate 7 is made of square steel tubing, and the thermal insulation material filled in the mounting plate 7 is preferably aluminum silicate insulation cotton, but can be other thermal insulation materials such as mineral wool board, rock wool board, and glass fiber wool board.

[0069] For example, such as Figure 4 and Figure 5 As shown, there are multiple locking buckles 8, which are distributed at intervals along the circumference of the mounting pad 7 to improve the retraction reliability of the pressure plate 3.

[0070] For example, the pressure plate 3 is fixed to the cover plate body 1 by locking screws.

[0071] For example, such as Figure 4 As shown, one end of the pressure plate 3 and / or the cover plate body 1 is rotatably connected to the mounting pad 7 via a hinge 9 around a horizontal axis. Gas spring struts 10 are provided on both the left and right sides of the cover plate body 1. One end of the gas spring strut 10 is rotatably connected to the mounting pad 7, and the other end is rotatably connected to the pressure plate 3. The gas spring strut 10 can, through its own telescopic movement, drive the pressure plate 3 and the cover plate body 1 to rotate together around the hinge 9, thereby opening the discharge channel 1001 of the discharge vibrating trough 1000 from the top, facilitating the inspection and cleaning of residual tobacco shreds within the discharge channel 1001 by staff.

[0072] For example, such as Figure 4 As shown, the pressure plate 3 is also equipped with a handle 14 so that the staff can pull up the cover plate body 1 and the pressure plate 3.

[0073] For example, such as Figure 2 and Figure 3 As shown, adjacent heating groove cover plate units 100 are spaced apart, and a crossbeam 200 is provided between adjacent heating groove cover plate units 100. The crossbeam 200 is a hollow structure and is filled with heat insulation material to improve heat insulation performance.

[0074] Exemplarily, the crossbeam 200 is made of square steel tube, and the heat insulation material filled in the crossbeam 200 is preferably aluminum silicate insulation cotton, and can be selected from other heat insulation materials such as mineral wool board, rock wool board, glass fiber cotton board, etc.

[0075] Specifically, the bottom surface of the mounting pad 7 serves as the second steam contact surface, and the bottom surface of the crossbeam 200 serves as the third steam contact surface. By utilizing the intermetallic heat exchange characteristics, the heat of the cover plate body 1 can be transferred to the mounting pad 7 and the crossbeam 200 in sequence, so that the temperature of the second steam contact surface and the third steam contact surface also rises to above the highest temperature (80℃) at which steam can condense, thereby avoiding the formation of condensed water on the second steam contact surface and the third steam contact surface, and further reducing or avoiding the formation of wet tobacco.

[0076] Exemplarily, as shown in Figure 1 The central control unit includes a programmable logic controller, an auxiliary analog module, a digital module, and a communication module. The auxiliary analog module is electrically connected to the input end of the programmable logic controller and the temperature detection unit, respectively. The digital module is electrically connected to the output end of the programmable logic controller and the heating control unit, respectively. The auxiliary analog module is electrically connected to the temperature detection unit through the communication module, and the digital module is electrically connected to the heating control unit through the communication module.

[0077] Exemplarily, the programmable logic controller adopts a PID control mode. It collects the electrical signals returned by the temperature detection unit (processed by the auxiliary analog module), calculates through proportional-integral-derivative, outputs an adjustment signal to the heating control unit through the digital module, and adjusts the output of the heating control unit in a negative feedback control mode. The programmable logic controller can save the adjustment history of controlling the heating control unit to record the heating curve.

[0078] Exemplarily, the programmable logic controller, the auxiliary analog module, the digital module, and the communication module are all conventional elements in the prior art, and their specific structures will not be described here.

[0079] Exemplarily, the heating control unit includes a three-phase full-isolation AC voltage regulation module, which is electrically connected to the power supply end of the heating groove cover plate unit 100 to control the input voltage of the heating groove cover plate unit 100.

[0080] Exemplarily, the power supply protection unit includes a circuit breaker with leakage protection, which is arranged on the power supply line of the heating groove cover plate unit 100. Specifically, the power supply protection unit is arranged between the heating groove cover plate unit 100 and the heating control unit to protect the heating groove cover plate unit 100 and the line from adverse voltages such as overcurrent, overvoltage, undervoltage, and surge, thereby ensuring the safe operation of the heating groove cover plate unit 100.

[0081] For example, the human-computer interaction unit comprises a touch display screen, which is used to display device information, process information and set temperature control parameters. A user can obtain process information and alarm information through the touch display screen, and can also set process parameters and control a flow through the touch display screen.

[0082] It should be noted that the above only describes the preferred embodiments of the present application and the principles of the applied technology. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and that various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the scope of the present application.
