Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to air conditioning units and their temperature and humidity control devices. Background Technology

[0002] Traditional tobacco production workshops require storage cabinets to process and store tobacco from various tobacco processing lines. Tobacco factories need a constant temperature and humidity environment when storing materials, and often use centralized air conditioning systems, setting up large combined air conditioning units to handle the temperature and humidity load of the entire space.

[0003] However, existing technologies have the following problems:

[0004] 1. The actual space required for constant temperature and humidity is only the storage tank section, and the storage space of the storage tank is much smaller than the total space. The existing technology is for cooling the large space, which cannot provide precise local cooling. Maintaining constant temperature and humidity in the entire space will result in energy waste.

[0005] 2. Different types of tobacco have different requirements for temperature and humidity, requiring precise control of temperature and humidity in the storage tank. However, the existing constant temperature and humidity storage tanks are open designs with poor sealing, and cannot quickly reach the required temperature and humidity within a certain time.

[0006] 3. The tobacco particles are small, and the air ducts inside the storage tank can easily draw the tobacco into the air handling unit, blocking the air vents. Summary of the Invention

[0007] To address the technical problems of energy waste, poor sealing, and easy clogging of air vents in existing technologies, this invention provides an air conditioning unit and its temperature and humidity control device.

[0008] The present invention adopts the following technical solution.

[0009] A first aspect of the present invention provides a temperature and humidity control device, comprising:

[0010] Storage cabinets are used for storing materials;

[0011] A sealing assembly, connected to the storage tank, is used to seal the storage tank;

[0012] A temperature and humidity control component, connected to the storage tank, is used to control the temperature and humidity of the material.

[0013] An orifice plate, connected to the storage tank, is used to intercept materials;

[0014] The controller is connected to the temperature and humidity control component and controls the temperature and humidity of the material by adjusting the working state of the temperature and humidity control component.

[0015] Preferably, the number of storage tanks is several, and the several storage tanks are spliced ​​together.

[0016] Preferably, the sealing assembly includes a first telescopic door and a second telescopic door connected to the controller, with the first telescopic door and the second telescopic door respectively located at the upper and lower ends of the storage tank.

[0017] Preferably, the temperature and humidity control component includes an air supply duct, a return air duct, and a mixing section, a filtering section, a cooling section, a humidifying section, and an air supply section connected in sequence. The air supply duct extends into the storage tank and is connected to the air supply section. The return air duct extends into the storage tank and is connected to the mixing section. The mixing section is used to mix fresh air with the air supplied by the return air duct. The filtering section is used to filter impurities in the air. The cooling section is used to cool the air. The humidifying section is used to humidify the air. The air supply section includes a fan and is used to supply air into the air supply duct.

[0018] Preferably, the surface cooling section is connected to a cold source, which is used to provide low-temperature cold water to the surface cooling section.

[0019] Preferably, one end of the return air duct is provided with a return air inlet, and the perforated plate is disposed above the return air inlet.

[0020] Preferably, the storage tank is equipped with a material detection module and several temperature sensors, humidity sensors, air supply pipes and return air pipes, and an air valve is installed on the air supply pipe.

[0021] Preferably, the material detection module detects the thickness and position of the material stack in real time during the process of the material entering the storage tank, opens the air valve of the air supply pipe at the material stack position, and increases the air supply volume of the air supply section based on the material stack thickness.

[0022] Preferably, when the material detection module detects that the storage tank is full of material, the temperature sensor detects the real-time temperature T1 of the air inside the storage tank, the humidity sensor detects the real-time humidity W1 of the air inside the storage tank, the controller compares T1 with the set temperature T, compares W1 with the set humidity W, and adjusts the working state of the cooling section and the humidification section based on the comparison results.

[0023] Preferably, if the controller determines that T1 > T and W1 > W, the controller reduces the air temperature and humidity by increasing the cooling capacity of the surface cooling section and decreasing the humidification capacity of the humidification section.

[0024] If the controller determines that T1 > T and W1 = W, the controller will increase the cooling capacity of the surface cooling section and increase the humidification capacity of the humidification section to reduce the air temperature and maintain the air humidity.

[0025] If the controller determines that T1 > T and W1 < W, the controller will increase the cooling capacity of the surface cooling section and the humidification capacity of the humidification section to reduce the air temperature and increase the air humidity.

[0026] Preferably, if the controller determines that T1 = T and W1 > W, the controller maintains the cooling capacity of the surface cooling section and reduces the humidification capacity of the humidification section to maintain the air temperature and reduce the air humidity.

[0027] If the controller determines that T1 = T and W1 = W, the controller maintains the air temperature and humidity by maintaining the cooling capacity of the surface cooling section and the humidification capacity of the humidification section.

[0028] If the controller determines that T1 = T and W1 < W, the controller maintains the cooling capacity of the surface cooling section and increases the humidification capacity of the humidification section to maintain the air temperature and increase the air humidity.

[0029] Preferably, if the controller determines that T1 < T and W1 > W, the controller increases the air temperature and decreases the air humidity by reducing the cooling capacity of the surface cooling section and the humidification capacity of the humidification section.

[0030] If the controller determines that T1 < T and W1 = W, the controller increases the air temperature and maintains the air humidity by reducing the cooling capacity of the surface cooling section and the humidification capacity of the humidification section.

[0031] If the controller determines that T1 < T and W1 < W, the controller increases the air temperature and humidity by reducing the cooling capacity of the surface cooling section and increasing the humidification capacity of the humidification section.

[0032] Preferably, the temperature and humidity control device further includes:

[0033] The first conveying module is located above the storage tank and is used to send the material processed in the previous process into the storage tank;

[0034] The second conveying module is located below the storage tank and is used to convey the material in the storage tank into the processing area of ​​the next process.

[0035] Both the first conveying module and the second conveying module are connected to the controller.

[0036] A second aspect of the present invention provides an air conditioning unit, including the temperature and humidity control device provided in the first aspect of the present invention.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] This invention, by setting a temperature and humidity control component connected to the storage tank, can independently supply cooling and humidity control, only responsible for the constant temperature and humidity requirements of the storage tank, eliminating the problem of large-space cooling and humidity control, thus avoiding energy waste. By setting a sealing component connected to the storage tank, the storage tank can be sealed to ensure its airtightness. By setting a perforated plate to intercept materials, it prevents materials from being sucked into the air handling unit and does not block the air vents.

[0039] In addition, by connecting several storage tanks together as needed, the material processing capacity can be increased and the utilization effect can be improved.

[0040] The upper part of the storage tank is sealed by the first telescopic door and the lower part of the storage tank is sealed by the second telescopic door, which separates the internal space of the storage tank from the external space and improves the airtightness of the storage tank.

[0041] The return air duct delivers air from the storage tank to the mixing section, where fresh air is mixed with the air delivered by the return air duct. The air then enters the filtration section, where impurities in the air are filtered out. The controller controls the surface cooling section and the humidification section to regulate the temperature and humidity of the air. Finally, the air supply section delivers the air to the storage tank through the air supply duct, thereby regulating the temperature and humidity of the material.

[0042] Low-temperature chilled water is supplied to the surface cooling section by a cold source to humidify the air in the surface cooling section and improve the effect of regulating air humidity.

[0043] The perforated plate is placed above the return air inlet to prevent materials from entering the return air duct through the return air inlet, thereby preventing the air inlet from being blocked and ensuring the normal operation of the temperature and humidity control components.

[0044] The material detection module, along with several temperature and humidity sensors, air supply ducts, and return air ducts, are all located inside the storage cabinet, without affecting the material production process. The material detection module can detect the thickness and position of the material stack, and the temperature and humidity of the air at different locations can be detected by several temperature and humidity sensors. In conjunction with the air valves, air supply ducts, and return air ducts, the temperature and humidity of the material can be precisely adjusted.

[0045] The material detection module detects that the thicker the material stack, the higher the power of the air supply section fan and the greater the air volume, ensuring that the air volume matches the material volume. Based on the material stack position, the air valve in the air supply duct at the material stack position is opened to achieve precise air supply and reduce overall energy consumption while ensuring the temperature and humidity regulation effect.

[0046] The controller compares the real-time temperature detected by the temperature sensor with the set temperature, and the real-time humidity detected by the humidity sensor with the set humidity. Based on the comparison results, it adjusts the working status of the cooling section and the humidification section to regulate the temperature and humidity of the air so that the temperature and humidity of the material meet the requirements.

[0047] The first conveying module can send the material processed by the previous process into the storage tank, and the second conveying module can send the material in the storage tank into the processing area of ​​the next process, which facilitates material transportation.

[0055] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. The embodiments described in this application are merely some embodiments of this invention, and not all embodiments. Based on the spirit of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this invention.

[0056] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention.

[0057] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0058] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0059] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0060] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0061] like Figure 1 As shown, Embodiment 1 of the present invention provides a temperature and humidity control device, comprising:

[0062] Storage cabinet 1 is used for storing materials;

[0063] A sealing assembly, connected to the storage tank 1, is used to seal the storage tank 1;

[0064] A temperature and humidity control component, connected to storage tank 1, is used to control the temperature and humidity of the material.

[0065] Perforated plate 2, connected to the storage tank 1, is used to intercept materials;

[0066] The controller is connected to the temperature and humidity control component and controls the temperature and humidity of the material by adjusting the working state of the temperature and humidity control component.

[0067] This invention, by setting a temperature and humidity control component connected to the storage tank 1, can process it independently, changing from temperature and humidity control of the entire space to temperature and humidity control of the storage tank 1. This eliminates the problem of large-space cooling and humidity control, avoiding energy waste. By setting a sealing component connected to the storage tank 1, the storage tank 1 can be sealed, separating the storage tank 1 from the large space and ensuring the airtightness of the storage tank 1. By setting a perforated plate 2 to intercept materials, it prevents materials from being sucked into the air handling unit and does not block the air vents.

[0068] Embodiment 2 of the present invention provides a temperature and humidity control device, specifically a modularly assembled temperature and humidity control device with top-supply and bottom-return configuration. The material is tobacco shreds, and the temperature and humidity requirements for tobacco shred storage vary. The storage cabinet 1 and temperature and humidity control components are integrated into a single design. The supply air duct 3 and return air duct 4 are located inside the storage cabinet 1, forming an top-supply and bottom-return air circulation pattern, optimizing the airflow and improving air circulation efficiency. The air valve 14, located closest to the tobacco shreds, is adjusted according to their stacking position to quickly bring the air inside the storage cabinet 1 to the required temperature and humidity, thus enabling precise control of the tobacco shreds. A perforated plate 2 is installed inside the storage cabinet 1 to prevent the return air from drawing in tobacco shreds. The storage cabinet 1 is also expandable; multiple storage cabinets 1 can be modularly assembled to improve usability. The temperature and humidity control device includes:

[0069] Storage cabinet 1 is used for storing tobacco shreds;

[0070] A sealing assembly, connected to the storage tank 1, is used to seal the storage tank 1;

[0071] A temperature and humidity control component, connected to the storage tank 1, is used to control the temperature and humidity of the tobacco shreds;

[0072] Perforated plate 2, connected to the storage tank 1, is used to intercept tobacco shreds;

[0073] The controller is connected to the temperature and humidity control component and controls the temperature and humidity of the tobacco by adjusting the working state of the temperature and humidity control component.

[0074] It can provide cooling and humidity control independently, eliminating the problem of large-space cooling and humidity control and avoiding energy waste. It can also seal the storage tank 1 to ensure its airtightness, preventing the tobacco from being drawn into the air handling unit and avoiding clogging the air vents.

[0075] Preferably, but not restrictively, the number of storage tanks 1 is several, and several storage tanks 1 are modularly spliced ​​together.

[0076] Several storage tanks 1 can be spliced ​​together as needed. The temperature and humidity of the several storage tanks 1 are controlled by a temperature and humidity control component, which can increase the processing capacity of tobacco and improve the effect of use.

[0077] like Figure 2 , 3 As shown in Figure 4, preferably but not limitingly, the sealing assembly includes a first telescopic door 18 and a second telescopic door 19 connected to the controller, with the first telescopic door 18 and the second telescopic door 19 respectively located at the upper and lower ends of the storage tank 1.

[0078] Both the first telescopic door 18 and the second telescopic door 19 have heat preservation functions to prevent the outside environment from affecting the internal temperature of the storage tank 1. The first telescopic door 18 closes the upper end of the storage tank 1, and the second telescopic door 19 closes the lower end of the storage tank 1, so that the internal space of the storage tank 1 is separated from the external space, thereby improving the airtightness of the storage tank 1.

[0079] like Figure 5 As shown, preferably but not limitingly, the temperature and humidity control assembly includes an air supply duct 3, a return air duct 4, and a mixing section 5, a filtering section 6, a cooling section 7, a humidifying section 8, and an air supply section 9 connected in sequence. The air supply duct 3 extends into the storage tank 1 and is connected to the air supply section 9. The return air duct 4 extends into the storage tank 1 and is connected to the mixing section 5. The mixing section 5 is used to mix fresh air with the air supplied by the return air duct 4. The filtering section 6 is used to filter impurities in the air. The cooling section 7 is used to cool the air. The humidifying section 8 is used to humidify the air. The air supply section 9 includes a fan and is used to supply air into the air supply duct 3.

[0080] The return air duct 4 delivers the air in the storage tank 1 to the mixing section 5. The mixing section 5 mixes the fresh air with the air delivered by the return air duct 4, and then the air enters the filter section 6. The filter section 6 filters out impurities in the air. The controller controls the cooling section 7 and the humidification section 8 to adjust the temperature and humidity of the air. Then the air supply section 9 delivers the air to the storage tank 1 through the air supply duct 3, thereby adjusting the temperature and humidity of the tobacco.

[0081] Further preferred, but not limiting, is that the surface cooling section 7 is connected to a cold source 10, which is used to provide low-temperature cold water to the surface cooling section 7.

[0082] Low-temperature cold water is supplied to the surface cooling section 7 through the cold source 10 to humidify the air in the surface cooling section 7 and improve the effect of regulating air humidity.

[0083] Further preferred but not limiting, the storage tank 1 is equipped with a material detection module and several temperature sensors 12, humidity sensors 13, air supply pipes 3 and return air pipes 4, and an air valve 14 is installed on the air supply pipes 3.

[0084] Several temperature sensors 12 and humidity sensors 13 are arranged along the depth of the storage tank 1. The material detection module, along with the temperature sensors 12 and humidity sensors 13, the air supply duct 3, and the return air duct 4, are all located inside the storage tank 1, without affecting the tobacco production process. The material detection module is preferably a 3D vision imaging system, which generates three-dimensional point cloud data of the tobacco surface through multi-angle cameras or structured light scanning, and then analyzes the thickness and position of the tobacco stack. The temperature and humidity of the air at different locations can be detected by the temperature sensors 12 and humidity sensors 13. In conjunction with the air valve 14, the air supply duct 3, and the return air duct 4, the temperature and humidity of the tobacco can be precisely adjusted. This solves the problem of existing storage tanks with temperature and humidity control, where the storage tank is separated from the air conditioning unit and connected by air ducts. The air ducts are usually located on the upper and lower sides of the storage tank. The air supply and return air ducts of the air conditioning unit occupy a lot of space, and the pipeline installation is difficult, making later operation, maintenance, and upkeep difficult.

[0085] Further preferred, but not limiting, the material detection module detects the thickness and position of the tobacco stack in real time during the process of tobacco entering the storage tank 1, opens the air valve 14 of the air supply pipe 3 at the tobacco stack position, and increases the air supply volume of the air supply section 9 based on the tobacco stack thickness.

[0086] The material detection module detects that the thicker the tobacco stack, the higher the power of the fan in the air supply section 9 and the greater the air volume, ensuring that the air volume matches the amount of tobacco. Based on the position of the tobacco stack, the air valve 14 at the position of the air supply pipe 3 is opened to achieve precise air supply, reducing overall energy consumption while ensuring the temperature and humidity regulation effect.

[0087] Further preferred, but not limiting, when the material detection module detects that the storage tank 1 is full of tobacco, the temperature sensor 12 detects the real-time temperature T1 of the air inside the storage tank 1, and the humidity sensor 13 detects the real-time humidity W1 of the air inside the storage tank 1. The controller compares T1 with the set temperature T and W1 with the set humidity W, and adjusts the working state of the cooling section 7 and the humidification section 8 based on the comparison results.

[0088] The controller compares the real-time temperature detected by the temperature sensor 12 with the set temperature, and the real-time humidity detected by the humidity sensor 13 with the set humidity. Based on the comparison results, it adjusts the working state of the cooling section 7 and the humidification section 8 to regulate the temperature and humidity of the air so that the temperature and humidity of the tobacco meet the requirements.

[0089] Further preferred, but not limiting, if the controller determines that T1 > T and W1 > W, the controller reduces the air temperature and humidity by increasing the cooling capacity of the surface cooling section 7 and decreasing the humidification capacity of the humidification section 8;

[0090] If the controller determines that T1 > T and W1 = W, the controller will increase the cooling capacity of the surface cooling section 7 and increase the humidification capacity of the humidification section 8 to reduce the air temperature and maintain the air humidity.

[0091] If the controller determines that T1 > T and W1 < W, the controller will increase the cooling capacity of the surface cooling section 7 and the humidification capacity of the humidification section 8 to reduce the air temperature and increase the air humidity.

[0092] Further preferred, but not limiting, if the controller determines that T1 = T and W1 > W, the controller maintains the cooling capacity of the surface cooling section 7 and reduces the humidification capacity of the humidification section 8 to maintain the air temperature and reduce the air humidity.

[0093] If the controller determines that T1 = T and W1 = W, the controller maintains the air temperature and humidity by maintaining the cooling capacity of the surface cooling section 7 and the humidification capacity of the humidification section 8.

[0094] If the controller determines that T1 = T and W1 < W, the controller maintains the cooling capacity of the surface cooling section 7 and increases the humidification capacity of the humidification section 8 to maintain the air temperature and increase the air humidity.

[0095] Further preferred, but not limiting, if the controller determines that T1 < T and W1 > W, the controller increases the air temperature and decreases the air humidity by reducing the cooling capacity of the surface cooling section 7 and the humidification capacity of the humidification section 8.

[0096] If the controller determines that T1 < T and W1 = W, the controller increases the air temperature and maintains the air humidity by reducing the cooling capacity of the surface cooling section 7 and the humidification capacity of the humidification section 8.

[0097] If the controller determines that T1 < T and W1 < W, the controller increases the air temperature and humidity by reducing the cooling capacity of the surface cooling section 7 and increasing the humidification capacity of the humidification section 8.

[0098] Further preferred, but not restrictive, is that if the humidification section 8 is already in the off state, the humidification amount of the humidification section 8 will not be further reduced.

[0099] In view of the different temperature and humidity corresponding to different types of tobacco, the present invention can adjust the temperature and humidity in the storage tank 1 by adjusting the operating mode of the temperature and humidity control component, and control the temperature and humidity by increasing the cooling capacity of the surface cooling section 7 and the humidification capacity of the humidification section 8.

[0100] like Figure 6As shown, in a further preferred but not limiting manner, one end of the return air duct 4 is provided with a return air inlet 11, and the perforated plate 2 is provided above the return air inlet 11. The perforated plate 2 is preferably a porous medium base plate.

[0101] The perforated plate 2 is positioned above the return air inlet 11 to prevent tobacco from entering the return air duct 4 through the return air inlet 11, thereby preventing the air inlet from being blocked and ensuring the normal operation of the temperature and humidity control components.

[0102] As a further preferred but not limiting option, one end of the air supply pipe 3 is provided with an air supply port 17, which is located above the perforated plate 2.

[0103] The air circulation forms an upward supply and downward return pattern, which optimizes the airflow pattern and improves the air circulation effect.

[0104] In a further preferred but not limiting manner, the return air duct 4 and the supply air duct 3 are both located on the inner edge of the storage tank 1.

[0105] Avoid interfering with the stacking of tobacco.

[0106] Preferably, but not limitingly, the temperature and humidity control device further includes:

[0107] The first conveying module 15 is located above the storage tank 1 and is used to feed the tobacco shreds processed in the previous process into the storage tank 1;

[0108] The second conveying module 16 is located below the storage tank 1 and is used to convey the tobacco in the storage tank 1 into the processing area of ​​the next process.

[0109] Both the first conveying module 15 and the second conveying module 16 are connected to the controller.

[0110] The first conveying module 15 can send the tobacco shreds processed in the previous process into the storage tank 1 for fermentation. After fermentation is completed, the second conveying module 16 can send the tobacco shreds in the storage tank 1 into the processing area of ​​the next process, which facilitates the transportation of tobacco shreds.

[0111] Embodiment 2 of the present invention provides an air conditioning unit, including the temperature and humidity control device provided in Embodiment 1.

[0112] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0113] This invention, by setting a temperature and humidity control component connected to the storage tank, can independently supply cooling and humidity control for it, only responsible for the constant temperature and humidity requirements of the storage tank, eliminating the problem of large-space cooling and humidity control, thus avoiding energy waste. By setting a sealing component connected to the storage tank, the storage tank can be sealed to ensure its airtightness. By setting a perforated plate to intercept tobacco, the tobacco is prevented from being sucked into the air handling unit and will not block the air vents.

[0114] In addition, by splicing together several storage tanks as needed, the amount of tobacco that can be processed can be increased, thus improving the efficiency of use.

[0115] The upper part of the storage tank is sealed by the first telescopic door and the lower part of the storage tank is sealed by the second telescopic door, which separates the internal space of the storage tank from the external space and improves the airtightness of the storage tank.

[0116] The return air duct delivers air from the storage tank to the mixing section, where fresh air is mixed with the air delivered by the return air duct. The air then enters the filtration section, where impurities in the air are filtered out. The controller controls the cooling and humidification sections to regulate the temperature and humidity of the air. Finally, the supply air section delivers air through the supply air duct to the storage tank, thereby regulating the temperature and humidity of the tobacco.

[0117] Low-temperature chilled water is supplied to the surface cooling section by a cold source to humidify the air in the surface cooling section and improve the effect of regulating air humidity.

[0118] The perforated plate is placed above the return air inlet to prevent tobacco from entering the return air duct through the return air inlet, thereby preventing the air inlet from being blocked and ensuring the normal operation of the temperature and humidity control components.

[0119] The material detection module, along with several temperature and humidity sensors, air supply ducts, and return air ducts, are all located inside the storage cabinet, without affecting the tobacco production process. The material detection module can detect the thickness and position of the tobacco stack, and the temperature and humidity of the air at different locations can be detected by several temperature and humidity sensors. In conjunction with the air valve, air supply duct, and return air duct, the temperature and humidity of the tobacco can be precisely adjusted.

[0120] The material detection module detects that the thicker the tobacco stack, the higher the power of the air supply section fan and the greater the air volume, ensuring that the air volume matches the amount of tobacco. Based on the position of the tobacco stack, the air valve in the air supply duct at the tobacco stack position is opened to achieve precise air supply and reduce overall energy consumption while ensuring the temperature and humidity regulation effect.

[0121] The controller compares the real-time temperature detected by the temperature sensor with the set temperature, and the real-time humidity detected by the humidity sensor with the set humidity. Based on the comparison results, it adjusts the working status of the cooling section and the humidification section to regulate the temperature and humidity of the air so that the temperature and humidity of the tobacco meet the requirements.

[0122] The first conveying module can send the tobacco shreds processed in the previous process into the storage tank, and the second conveying module can send the tobacco shreds in the storage tank into the processing area of ​​the next process, which facilitates the transportation of tobacco shreds.
