Description

Technical Field

[0001] The utility model relates to a temperature and humidity sensor device for tobacco-loading rooms in intensive curing rooms, belonging to the technical field of tobacco leaf curing equipment. Background Art

[0002] In tobacco leaf baking, it is usually necessary to adjust the baking process according to the temperature and humidity in the tobacco loading room. The current tool for detecting temperature and humidity is a temperature and humidity sensor, which consists of a sensor base, a kettle, a dry-bulb temperature sensor probe and a wet-bulb temperature sensor probe. When in use, the sensor is placed at different heights in the tobacco loading room to detect the temperature and humidity of different parts. However, the applicant found that the existing temperature and humidity sensors have at least the following problems during the baking process: First, the kettle often needs to be replenished with water before baking, otherwise it is easy to cause a lack of kettle during the baking process. At this time, the wet-bulb temperature sensor probe also detects the dry-bulb temperature instead of the wet-bulb temperature, and the lack of kettles is easy to cause the baking room to be ventilated and dehumidified for a long time, which will affect the execution of the baking process and the waste of baking energy; second, the sensor device needs to be placed in the internal position of the top and bottom layers of tobacco leaves during the tobacco loading process, which often interferes with the tobacco loading operation, and sometimes the water in the kettle is squeezed out by accident, thereby affecting the normal use of the temperature and humidity sensor device. Utility Model Content

[0003] Based on the above, the utility model provides a temperature and humidity sensor device for a smoke chamber in a dense flue-curing room to overcome the deficiencies of the prior art.

[0004] The technical solution of the utility model is: a temperature and humidity sensor device for smoke chamber in a dense curing room, comprising:

[0005] A sensing unit, comprising a sensor base, a kettle, a dry-bulb temperature sensor probe and a wet-bulb temperature sensor probe, wherein the kettle is mounted on the sensor base, and the dry-bulb temperature sensor probe and the wet-bulb temperature sensor probe are respectively mounted on both sides of the sensor base;

[0006] The liquid replenishment unit includes a liquid level sensor, a liquid replenishment tank, a liquid pump, a liquid replenishment tube and a controller. The liquid level sensor is arranged in the kettle, one end of the liquid replenishment tube is connected to the kettle, and the other end is connected to the liquid replenishment tank through the liquid pump. The liquid level sensor and the liquid pump are both electrically connected to the controller.

[0007] In one example, it also includes a lifting unit, which includes a pulley, a pull rope and a winding disk. A plurality of pulleys are arranged at intervals on the inner top surface and the side surface of the smoking chamber. The winding disk is arranged on the side surface of the smoking chamber. One end of the pull rope is connected to the top of the kettle, and the other end is connected to the winding disk after a plurality of pulleys in sequence.

[0008] In one example, the sensor base is provided with stop bars at intervals around the periphery of the kettle.

[0009] In one example, the controller is a temperature and humidity automatic controller for a concentrated baking room.

[0010] The beneficial effects of the utility model are as follows: by setting a liquid level sensor, a liquid replenishing tank and a liquid pump, the kettle can be automatically replenished with water, avoiding the trouble of the kettle being short of water during the baking process, thereby ensuring the accurate measurement of the wet-bulb temperature sensor probe, and improving the reliability and execution efficiency of the baking process. Through the pulley, the pull rope and the winding disk, the sensor unit can be moved down (or up) before loading the cigarette, and then moved up (or down) to a predetermined position after loading the cigarette, avoiding interference with the sensor device during the cigarette loading process. At the same time, the setting of the baffle rod also effectively prevents the water in the kettle from overflowing due to accidental contact, thereby ensuring the stability and reliability of the sensor.

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0019] See also Figures 1 to 3 The present embodiment provides a smoke chamber temperature and humidity sensor device for a densely-cured room, including a sensor unit and a liquid replenishment unit.

[0020] The sensing unit includes a sensor base 11, a kettle 12, a dry-bulb temperature sensor probe 13 and a wet-bulb temperature sensor probe 14. The kettle 12 is installed on the sensor base 11. The dry-bulb temperature sensor probe 13 and the wet-bulb temperature sensor probe 14 are respectively installed on both sides of the sensor base 11. The dry-bulb temperature sensor probe 13 is used to detect the air temperature of the baking room. The wet-bulb temperature sensor probe 14 is used to detect the air temperature when the water vapor in the air reaches saturation under the air state of the same enthalpy value in the baking room.

[0021] The liquid replenishment unit includes a liquid level sensor 21, a liquid replenishment tank 22, a liquid pump, a liquid replenishment tube 23 and a controller. The liquid level sensor 21 is vertically installed in the kettle 12 for sensing the water level in the kettle 12. One end of the liquid replenishment tube 23 is connected to the kettle 12, and the other end is connected to the liquid replenishment tank 22 through the liquid pump. The liquid level sensor 21 and the liquid pump are both electrically connected to the controller. The controller is a temperature and humidity automatic controller for the intensive baking room, which is convenient for viewing and control, so that the kettle 12 can be automatically replenished with water to avoid water shortage in the kettle 12.

[0022] In order to avoid water leakage, barrier rods 15 are provided at intervals around the outer periphery of the kettle 12 on the sensor base 11. The limiting effect of the barrier rods 15 can prevent the kettle 12 from being squeezed during operation and causing overflow from the socket corresponding to the wet bulb probe.

[0023] In order to facilitate operation, the device also includes a lifting unit, which includes a pulley 31, a pull rope 32 and a winding disk 33. Multiple pulleys 31 are installed at intervals on the inner top surface and side of the cigarette loading chamber, and the winding disk 33 is installed on the side of the cigarette loading chamber. One end of the pull rope 32 is connected to the top of the kettle 12, and the other end is connected to the winding disk 33 after passing through multiple pulleys 31 in sequence. The sensor unit can be raised and lowered through the winding disk 33. The advantage of this structure is that the sensor unit can be moved down (or up) through the winding disk 33 before loading cigarettes, and the sensor unit can be moved up (or down) to a predetermined position after loading cigarettes, thereby avoiding interference with the sensor device during the cigarette loading process.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
