Abstract
Description
Technical Field
[0001] The present application relates to the technical field of tobacco processing equipment, and in particular to a tobacco drying machine processing environment control device. Background Art
[0002] In the process of making tobacco, cigarette factories need to dry the tobacco to remove some of the moisture in the tobacco so that the moisture in the tobacco reaches the range required by the production process. The tobacco drying process is completed in a tobacco drying machine, and hot air is introduced into the tobacco drying machine to dry the tobacco. During the process, the drying effect is mostly controlled by controlling the humidity level of the hot air blown into the tobacco drying machine, or by controlling the humidity level of the tobacco itself when entering the tobacco drying machine. Both methods control the conditions before entering the tobacco drying machine. During the process of drying the tobacco, the actual drying effect of the tobacco changes dynamically, which makes the actual drying effect different from the expected one. Moreover, the above-mentioned control methods all require the installation of humidification equipment to humidify the hot air or tobacco, and the production cost is relatively high. Utility Model Content
[0003] The purpose of the present application is to provide a tobacco drying machine processing environment control device, which can more conveniently control the tobacco drying process, thereby effectively solving the deficiencies existing in the prior art.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0024] like Figure 1-Figure 2 As shown, the embodiment of the present application provides a tobacco cutter 100 processing technology environment control device, which is applied to the tobacco cutter 100 to dry tobacco cutters. In the past, when the tobacco cutters 100 were used to dry tobacco cutters, the tobacco cutters were mostly dried by controlling the moisture content of the tobacco cutters themselves when entering the tobacco cutters 100, or by controlling the humidity level of the hot air blown into the tobacco cutters 100. Both methods are achieved by controlling the factors and conditions before entering the tobacco cutters 100. In the actual drying process, the actual drying effect of the tobacco cutters is dynamically variable. Controlling the conditions before entering the tobacco cutters 100 cannot cope with the changes in the drying process, resulting in a difference between the actual drying effect and the expected drying effect, which affects the quality of the tobacco cutters. In addition, in the above two control methods, since the moisture content of the tobacco cutters and the hot air needs to be controlled, a humidifying device needs to be set up and a corresponding humidifying process needs to be formulated, and the production cost also increases accordingly. The tobacco cutters 100 processing technology environment control device of the present application is intended to improve the control accuracy of the tobacco cutters drying effect, so that the actual drying effect reaches the expected drying effect, and the production cost is reduced as much as possible.
[0025] The processing environment control device of the wire drying machine 100 includes a wire drying machine 100, which is used to dry the tobacco, and is provided with a dehumidification port, which is communicated with the inside of the wire drying machine 100, and also includes a hot air blower 200. The wire drying machine 100 has a tobacco feed port 101 and a discharge port 102. The tobacco is fed into the wire drying machine 100 through the feed port 101, and the dried tobacco is discharged from the discharge port 102. The hot air blower 200 blows hot air into the wire drying machine 100 through a pipeline, and the hot air dries the tobacco. The humid air generated by the drying machine 100 is discharged from the dehumidification port, and the first sensor 21 is also included. The first sensor 21 is arranged at the dehumidification port. The first sensor 21 is used to detect the humidity level of the humid airflow discharged from the dehumidification port. The humidity level of the humid airflow discharged here can reflect the drying effect of the tobacco. The controller 300 is also included. The controller 300 is electrically connected to the hot air blower 200. The controller 300 is electrically connected to the first sensor 21. When the tobacco is being dried by the dryer 100, if the first sensor 21 detects that the humidity of the airflow discharged from the dehumidification port is higher than a preset value, it indicates that there is too much moisture discharged from the dehumidification port. The first sensor 21 converts the detection result into an electrical signal and transmits it to the controller 300. After receiving the signal, the controller 300 controls the hot air blower 200 to reduce the wind speed to reduce the amount of hot air sent into the dryer 100, reduce the temperature inside the dryer 100, and reduce the drying effect on the tobacco, so that the tobacco can maintain appropriate moisture when the dryer 100 discharges the tobacco, so as to avoid the tobacco being over-dried and not meeting the production requirements. When the first sensor 21 detects When it is detected that the humidity of the air flow discharged from the dehumidification port is lower than the preset value, it indicates that the moisture discharged from the dehumidification port is too little. The first sensor 21 converts the detection result into an electrical signal and transmits it to the controller 300. After receiving the signal, the controller 300 controls the hot air blower 200 to increase the wind speed, increase the amount of hot air sent into the wire drying machine 100, increase the internal temperature of the wire drying machine 100, and improve the drying effect of the tobacco to avoid the tobacco still containing moisture exceeding the production requirements after drying. In this embodiment, the preset value can be set according to actual production needs.
[0026] Therefore, by detecting the humidity of the humid air flow discharged from the moisture outlet of the tobacco drying machine 100, the drying level of the tobacco inside the tobacco drying machine 100 can be reflected in real time and truly, and the amount of hot air sent into the tobacco drying machine 100 by the hot air blower 200 can be controlled in real time according to the humidity to achieve the adjustment of the drying level of the tobacco. The control is more convenient, and the actual drying effect of the tobacco can meet the expected standards. In addition, the structure of the entire device is simple, which is conducive to reducing production costs.
[0027] Preferably, a moisture discharge pipe 400 is provided at the moisture discharge outlet, one end of the moisture discharge pipe 400 is connected to the moisture discharge outlet, and the other end extends outward, and the first sensor 21 is provided on the moisture discharge pipe 400 to detect the humidity of the air flow flowing in the moisture discharge pipe 400. In this way, the installation and setting of the first sensor 21 is more convenient, and the layout of the equipment space is facilitated.
[0028] In one embodiment, a connecting pipe 500 is provided between the hot air blower 200 and the dehumidification pipe 400, one end of the connecting pipe 500 is connected to the hot air blower 200, and the other end of the connecting pipe 500 is connected to the dehumidification pipe 400, and in the flow direction of the airflow in the dehumidification pipe 400, the connection point of the connecting pipe 500 and the dehumidification pipe 400 is located in the downstream area of the first sensor 21, and a second sensor 22 is also provided on the dehumidification pipe 400, and the second sensor 22 is electrically connected to the controller 300, and the second sensor 22 is located between the connecting pipe 500 and Downstream of the connection point of the dehumidification pipeline 400, the second sensor 22 detects the humidity of the air flow in the corresponding area of the dehumidification pipeline 400. A part of the hot air provided by the hot air blower 200 flows to the dehumidification pipeline 400 through the connecting pipeline 500, and then mixes with the humid air flow discharged from the wire drying machine 100 before being discharged outward. The second sensor 22 detects the mixed humidity of the hot air provided by the hot air blower 200 and the humid air in the wire drying machine 100. In this embodiment, if the humidity detected by the second sensor 22 is less than the humidity detected by the first sensor 21, normal drying can be performed.
[0029] If the humidity detected by the second sensor 22 is greater than the humidity detected by the first sensor 21, it indicates that the air in the tobacco drying machine 100 is too dry. The wind speed of the hot air blower 200 should be reduced to avoid the tobacco being over-dried. In this case, there is also a probability of failure of the hot air blower 200, which facilitates the discovery and elimination of equipment failures.
[0030] In this embodiment, a third sensor 23 can also be set on the connecting pipe 500. The third sensor 23 is electrically connected to the controller 300. The third sensor 23 is used to detect the humidity level of the airflow in the connecting pipe 500, that is, the third sensor 23 can detect the humidity of the hot air provided by the hot air blower 200. By comparing the humidity detected by the third sensor 23 with the humidity detected by the first sensor 21, if the humidity detected by the first sensor 21 is greater than the humidity detected by the third sensor 23, normal drying can be performed.
[0031] If the humidity detected by the first sensor 21 is lower than the humidity detected by the third sensor 23, it indicates that the air in the tobacco drying machine 100 is too dry. The wind speed of the hot air blower 200 should be reduced to prevent the tobacco from being over-dried. In this case, there is also a probability of failure of the hot air blower 200, which facilitates the discovery and elimination of equipment failures.
[0032] The first sensor 21, the second sensor 22 and the third sensor 23 are all temperature and humidity sensors, and can also monitor the temperature during the drying process to meet the production requirements for the temperature of the tobacco in the process.
[0033] On the wire dryer 100, along the flow direction of the tobacco, the dehumidification port is located at the downstream end of the wire dryer 100, where the humidity of the airflow around the fully dried tobacco can be detected, and the data detection is more accurate. More preferably, the dehumidification port is located above the wire dryer 100, and the hot and humid airflow in the wire dryer 100 rises, which makes it easier to discharge the airflow and more accurate data detection.
