Description

Technical Field

[0001] The present application relates to the technical field of cigar curing barn equipment, and in particular to a temperature and humidity control system for a cigar curing barn. Background Art

[0002] The statements in this part only provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] In existing cigar curing barns, the control of temperature and humidity often depends on manual operation and simple mechanical equipment. These methods usually include using devices such as fans, heaters, and wet curtains, and through manual setting and adjustment to achieve a suitable environment. However, this method has many deficiencies: First, since temperature and humidity sensors cannot be set in every corner of the cigar curing barn, and the area of the cigar curing barn is often very large, local temperature and humidity detection cannot reflect the overall temperature and humidity in the cigar curing barn. In fact, even if the air supply and exhaust are always on, there are always some "dead corners" with poor air circulation in the cigar curing barn, and toxic gases and dirty air are likely to accumulate in this "dead corner" area, affecting the use. Second, considering the particularity of the cigar curing barn, in order to prevent the accumulation of toxic gases such as ammonia formed by rotten tobacco leaves, the cigar curing barn must be kept ventilated; but the cigar curing barn must also ensure a certain temperature and humidity. The existing technical means are basically to humidify when the humidity decreases and dehumidify when the humidity increases, and the same is true for temperature control, without considering whether the temperature and humidity in the external environment, the temperature and humidity of the air entering the cigar curing barn from the outside meet the standards or whether they will further affect the temperature and humidity in the cigar curing barn. Third, various temperature and humidity control devices are set in the cigar curing barn, which is itself a huge heat source, and some also have high radiation.

[0026] In this application, there are at least two air outlets. The purpose is that when initially supplying air to the cigar drying room 12, one air outlet is opened first. After an air circulation path from the air inlet to this air outlet is formed in the cigar drying room 12, the first air outlet is then closed and the second air outlet is opened. Then the air in the cigar drying room 12 will change the circulation path and flow from the air inlet to the second air outlet, thus forming a cyclic update of the air in the cigar drying room 12 to prevent the accumulation of toxic and dirty gases in individual areas of the cigar drying room 12 due to poor air circulation.

[0027] Among them, the data processing module establishes a space rectangular coordinate system, and the space rectangular coordinate system can be established with any plane in the cigar drying room 12 as the reference plane and any point in the reference plane as the origin.

[0028] Reference Figure 1, in one embodiment, the temperature and humidity control air inlet mechanism in the present application includes a second pipeline 15. One end of the second pipeline 15 is connected to one end of the fan 1 through a pipeline, and the other end of the second pipeline 15 is respectively connected to one end of a humidification pipeline, a dehumidification pipeline, and a normal pipeline through a pipeline; the other end of the fan 1 is communicated with the outside; the other ends of the humidification pipeline, the dehumidification pipeline, and the normal pipeline are respectively connected to one end of a third pipeline 16 through a pipeline; the other end of the third pipeline 16 is connected to the inside of the cigar tobacco drying room 12; a humidification valve 3, a one-way valve 4, a humidification mechanism 5, and a first check valve 6 are sequentially arranged on the humidification pipeline along the air inlet direction; the humidification pipeline is used to increase the humidity of the air entering the third pipeline 16; a dehumidification valve 7, a dehumidification mechanism 8, and a second check valve 9 are sequentially arranged on the dehumidification pipeline along the air inlet direction; the dehumidification pipeline is used to reduce the humidity of the air entering the third pipeline 16; a switch valve 10 and a pressure relief valve 11 are sequentially arranged on the normal pipeline along the air inlet direction; the fan 1, the humidification valve 3, the dehumidification valve 7, and the switch valve 10 are electrically connected to the control device.

[0029] The air inlet temperature and humidity sensor group includes a plurality of first temperature and humidity sensors 13 located on the pipe wall of the third pipeline 16 inside the cigar tobacco drying room 12; the air outlet temperature and humidity sensor group includes a plurality of second temperature and humidity sensors located at the air outlet inside the cigar tobacco drying room 12. The control module controls the temperature and humidity control air inlet mechanism to supply air to the cigar tobacco drying room, including the following steps: Step 1: Set the humidity threshold Td inside the cigar tobacco drying room 12 set ; Step 2: Obtain the humidity value Td measured by each first temperature and humidity sensor 13 k ; where k is the Kth air inlet; Step 3: Compare Td set and Td k values. When |Td set - Td k | ≤ M, the control module controls the fan 1 to start, opens the switch valve 10, and closes the humidification valve 3 and the dehumidification valve 7; When Td set - Td k > M, the control module controls the fan 1 to start, opens the humidification valve 3, and closes the switch valve 10 and the dehumidification valve 7; When Td k - Td set > M, the control module controls the fan 1 to start, opens the dehumidification valve 7, and closes the switch valve 10 and the humidification valve 3; where M is a set value, representing the allowable change range of the humidity inside the cigar tobacco drying room 12; Step 4: Control the air outlet mechanism to open the air outlet that is farthest from all the air inlets; when the humidity value measured by the second temperature and humidity sensor at this air outlet is greater than Td set -M and less than Td set +M, control the air outlet mechanism to close this air outlet and open the remaining air outlets; Step 5: When the humidity value measured by each second temperature and humidity sensor at all the air outlets is greater than Td set -M and less than Td set +M, the control module controls the fan 1 to start, opens the switch valve 10, and closes the humidifying valve 3 and the dehumidifying valve 7; Then return to Step 2.

[0030] The above control module controls the temperature and humidity regulated air inlet mechanism to supply air to the cigar drying room 12, and different air supply measures are taken according to the humidity situation in the cigar drying room 12. When the humidity in the cigar drying room 12 is in the range of [Td set -M, Td set +M], no humidifying and dehumidifying operations are performed on the supplied air; when the humidity in the cigar drying room 12 is below Td set -M, air humidifying operation is performed; when the humidity in the cigar drying room 12 is above Td set -M, air dehumidifying operation is performed.

[0031] In Step 4 of the above control module controlling the temperature and humidity regulated air inlet mechanism to supply air to the cigar drying room, the determination method for the air outlet that is farthest from all the air inlets is as follows: Step 1: Assume the number of air inlets is Q, the number of air outlets is H, let k = 1, and calculate the distance between the first air inlet and each air outlet: D 11 , D 12 , ···, D 1n , ···, D 1H ; and obtain the maximum value D 1max ; Step 2: Let k = k + 1; calculate the distance between the kth air inlet and each air outlet: D 11 , D k2 , ···, D kn , ···, D kH ; and obtain the maximum value D kmax ; where D kn represents the distance between the kth air inlet and the nth air outlet; n ∈ [1, H] and n is a positive integer; If k < Q, return to this step; If k = Q, enter Step 3; Step 3: Obtain the maximum value among D in Steps 1 and 2 kmax where k ∈ [1, Q] and k is a positive integer; the maximum value in D kmax The air outlet corresponding to the maximum value in D is the air outlet farthest from all the air inlets.

[0032] In Step 4 where the above control module controls the temperature and humidity regulating air inlet mechanism to supply air to the cigar drying room: The control module controls the air outlet mechanism to open the air outlet farthest from all the air inlets; when the humidity value measured by the second temperature and humidity sensor at this air outlet is greater than Td set - M and less than Td set + M, perform the following steps: S1: The control module controls the air outlet mechanism to close this air outlet; H = H - 1; where H is the number of air outlets; If H ≥ 1, enter Step S2, otherwise the process is completed; S2: Obtain the air outlet farthest from all the air inlets except all the above-mentioned air outlets, and open this air outlet; S3: Obtain the humidity value measured by the second temperature and humidity sensor at the air outlet opened in Step S2. When this humidity value is greater than Td set - M and less than Td set + M, return to Step S1.

[0033] In another embodiment, a heating mechanism 2 is provided between the second pipeline 15 and the fan 1; the heating mechanism 2 is electrically connected to the control device; the heating mechanism 2 is used to start the heating function when the temperature detected by any one of the second temperature and humidity sensors in the air outlet temperature and humidity sensor group is less than the set temperature value in the cigar drying room 12; It should be noted that the temperature control in the cigar drying room 12 is independent of the humidity control in the above-mentioned cigar drying room 12. As long as the temperature detected by any one of the second temperature and humidity sensors in the cigar drying room 12 is less than the set temperature value in the cigar drying room 12, no matter which one of the switching valve 10, the humidifying valve 3, and the dehumidifying valve 7 is opened at this time, as long as the heating function of the heating mechanism 2 is started, the air entering the cigar drying room 12 can be heated, so as to increase the temperature in the cigar drying room 12 and realize the temperature control in the cigar drying room 12.

[0034] Reference Figure 2, the heating mechanism 2 includes a heating box 20 with two ends respectively connected to one end of the first pipeline 14 and one end of the second pipeline 15 through pipelines. The other end of the first pipeline 14 is connected to the fan 1 through a pipeline; a heating cover 21 is detachably arranged on the top of the heating box 20, and a heating wire 22 is fixedly arranged in the heating box 20 below the heating cover 21; the heating wire 22 is electrically connected to the control device.

[0035] Reference Figure 5 and Figure 6 , the humidifying mechanism 5 includes a humidifying box 51, and pipeline interfaces are respectively arranged above and below the humidifying box 51; pure water is contained in the humidifying box 51; a humidifying plate 52 is fixedly arranged below the surface of the pure water, and a plurality of through holes are fixedly formed in the humidifying plate 52, and the sum of the cross-sectional areas of all the through holes is smaller than the planar area of the pipe orifice of the humidifying pipeline; a water filling port 55 is arranged on the top of the humidifying box 51, and a buckle cover is detachably connected to the water filling port 55; a heating rod 53 is arranged below the humidifying plate 52, the heating rod 53 is fixedly arranged on a mounting plate 54, and the mounting plate 54 is fixedly connected to the humidifying box 51; the heating rod 53 is electrically connected to the control device and is used to start the heating function when the temperature detected by any one of the second temperature and humidity sensors in the air outlet temperature and humidity sensor group is lower than the set temperature value in the cigar drying room 12. The purpose of the design of the heating rod 53 here: one is to increase the evaporation of the water in the humidifying box 51 and improve the humidifying effect; the other is to consider that when the heating mechanism 2 is heating, part of the heat of the air after heating will be lost when it enters the cigar drying room 12, and the design of the heating rod 53 can maintain the heating effect of the air.

[0036] Reference Figure 3 and Figure 4 , the dehumidifying mechanism 8 includes an upper cover plate 80 and a lower cover plate 81, and two connecting plates 83 located between the two and used for connecting to the dehumidifying pipeline through pipelines. A front cover plate 85 is detachably arranged in front of the dehumidifying mechanism 8, and a rear cover plate is arranged at the back; a filter screen 84 is arranged between the upper cover plate 80 and the lower cover plate 81, and a desiccant for moisture absorption is fixedly arranged on the filter screen 84; slide rails 82 are arranged in a matching manner below the upper cover plate 80 and above the lower cover plate 81, and the filter screen 84 is slidably arranged between the two slide rails 82.

[0037] In this application, it is considered that the cigar drying room 12 is in use, rather than the state when the cigar drying room is not put into use. Since the cigar drying room needs to maintain ventilation at all times, the air inlet remains in the air inlet state in this application, that is, the fan 1 remains in the running state.

[0038] A temperature and humidity control device applicable to a cigar drying room according to the present application can uniquely identify the positions of each air outlet through a data processing module. When sending air to the cigar drying room 12 through the temperature and humidity control air inlet mechanism, the air outlet mechanism is first controlled to open the air outlet farthest from all air inlets. When the temperature and humidity at this air outlet reach the set temperature and humidity range of the cigar drying room, the air outlet mechanism is controlled to close this air outlet and open the remaining air outlets. This operation ensures the air circulation quality in the cigar drying room 12 to a certain extent. The temperature and humidity control air inlet mechanism is arranged outside the cigar drying room 12, and its own heat generation and radiation have no impact on the internal environment of the cigar drying room 12. On the other hand, during the process of adjusting the humidity in the cigar drying room 12, the air inlet is heated by the heating mechanism 2 according to the detection result of the second temperature and humidity sensor, and the temperature adjustment is diffused to the inside of the cigar drying room by air circulation, and the temperature adjustment and humidity adjustment effects are obvious.

[0039] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.

Those skilled in the art should understand that various modifications or deformations that can be made without creative labor on the basis of the technical solution of the present application are still within the protection scope of the present application.
