Description

Technical Field

[0001] The invention belongs to the technical field of drying equipment, and in particular relates to a temperature and humidity automatic control type high-efficiency drying structure. Background Art

[0002] In a traditional drying kiln, the direction of the hot air outlet is fixed, the hot air flow direction is fixed, and there are some dead corners in the kiln, resulting in poor air flow, large temperature differences, and large humidity differences. As a result, the moisture content of different parts of the green body or different parts of each green body is different, which will cause defects such as cracking and deformation during the subsequent firing process.

[0003] When drying products with high moisture content or poor drainage, rapid drying can easily lead to problems such as rapid surface drainage and premature solidification of the surface layer, which closes the drainage channels of the capillary drainage holes in the blank, causing the product to crack and become scrapped. Traditional drying kilns reduce cracking defects by extending the drying cycle, but this is inefficient. Summary of the invention

[0004] The purpose of the present invention is to provide a temperature and humidity automatic control high-efficiency drying structure to solve the technical problems in the prior art that there are dead corners in the traditional drying kiln, resulting in different moisture contents of green bodies in different parts or different parts of each green body, and drying products with high moisture content or poor drainage easily leads to product cracking or low efficiency.

[0005] The technical solutions adopted to solve the above technical problems are: The invention discloses a temperature and humidity automatic control type high-efficiency drying structure, comprising: A drying chamber, wherein the drying chamber is connected to an exhaust pipe, the exhaust pipe is used to exhaust the humid air in the drying chamber, and a first valve is provided between the exhaust pipe and the drying chamber; A cyclone barrel, the cyclone barrel is located in the drying chamber, the cyclone barrel is provided with a first air inlet, a second air inlet and an air outlet, the first air inlet is connected to a hot air duct, the hot air duct is used to input hot air into the cyclone barrel, the second air inlet and the air outlet are respectively connected to the drying chamber, and the cyclone barrel is configured to mix the air in the first air inlet and the second air inlet and discharge it from the air outlet; A heating fan is located in the cyclone barrel and is configured to control the exhaust wind speed of the air outlet.

[0006] The present invention has at least the following beneficial effects: the first air inlet of the cyclone is connected to a hot air duct, the input hot air rotates through the cyclone, and is rotated and discharged from the air outlet into the drying chamber, so that products at various positions in the drying chamber are dried by the discharged drying medium, each product can be heated evenly, the drying degree of the same batch of products is the same, and the consistency of drying is improved.

[0007] When the drying medium is drying products with high moisture content or poor drainage, the first valve is closed. As the product is heated by the drying medium, the internal moisture evaporates in the drying chamber. The drying chamber is connected to the second air inlet, and the second air inlet inputs humid air in the drying chamber. The humid air is mixed with the hot air input from the first air inlet and the high-temperature and high-humidity drying medium is discharged to the drying chamber. The high humidity of the drying medium is used to inhibit the evaporation of moisture inside the product, so that the high temperature can be quickly transmitted to the interior of the entire product, so that the internal and external temperatures of the product reach a balanced state, thereby increasing the activity of water molecules inside the product.

[0008] Then open the first valve to discharge the wet air in the drying room into the exhaust duct, reduce the air humidity in the drying room, and make the drying medium discharged from the cyclone high temperature and low humidity, so that the moisture inside the product evaporates quickly without affecting the cracking of the product, thereby improving the drying efficiency of the product.

[0009] The heating fan can control the wind speed of the cyclone exhaust, which is convenient for adjusting the disturbance intensity of the drying medium according to different products or different drying stages, so as to achieve the appropriate convection intensity between the drying medium and the product.

[0010] As a further improvement of the above technical solution, a second valve is provided between the hot air duct and the drying chamber, and the second valve is used to control the air intake volume of the hot air duct.

[0011] Through the above arrangement, the second valve is adjusted to control the input amount of hot air from the hot air duct to adjust the discharge temperature of the drying medium.

[0012] As a further improvement of the above technical solution, the temperature and humidity automatic controlled high-efficiency drying structure also includes a temperature sensor and a controller. The temperature sensor is arranged in the drying chamber to obtain the temperature data in the drying chamber, and the controller is configured to control the switch of the second valve according to the temperature data of the drying chamber.

[0013] Through the above settings, the temperature sensor detects the temperature data in the drying chamber and transmits it to the controller. The controller compares the received temperature data with the drying temperature corresponding to the product or drying stage at this time, thereby increasing or decreasing the switch of the second valve and controlling the input amount of hot air, so that the temperature in the drying chamber can be accurately at the drying temperature of the corresponding product or drying stage.

[0014] As a further improvement of the above technical solution, the temperature and humidity automatic control high-efficiency drying structure also includes a dehumidification fan, which is connected to the exhaust duct and is used to drive the wet air to be discharged from the drying chamber.

[0015] Through the above arrangement, the dehumidification fan absorbs the moist air in the drying room under negative pressure.

[0016] As a further improvement of the above technical solution, the temperature and humidity automatic controlled high-efficiency drying structure also includes a humidity sensor and a controller. The humidity sensor is arranged in the drying chamber to obtain the relative humidity data of the drying chamber, and the controller is configured to control the rotation speed of the dehumidification fan according to the relative humidity data of the drying chamber.

[0017] Through the above settings, the humidity sensor detects the humidity data in the drying chamber and transmits it to the controller. The controller compares the received humidity data with the drying humidity corresponding to the product or drying stage at this time, thereby adjusting the speed of the dehumidification fan, and then adjusting the discharge amount of wet air in the drying chamber, so that the relative humidity in the drying chamber can accurately maintain the relative humidity of the corresponding product or drying stage.

[0018] As a further improvement of the above technical solution, the drying chamber is provided with an entrance and an exit, and both the entrance and the exit are provided with automatic doors, and the automatic doors are used to open or close the drying chamber.

[0019] Through the above arrangement, the product is input into the drying chamber through the entrance and output from the drying chamber through the exit. The automatic door can be opened and closed automatically. The closed automatic door seals the drying chamber to prevent external environmental factors from affecting the drying of the product.

[0020] As a further improvement of the above technical solution, the drying chamber is a cubic structure, the inlet and the outlet are respectively located at the two ends of the drying chamber along its length direction, the drying chamber is provided with multiple and connected in sequence along the length direction, and a partition is also provided between two adjacent drying chambers. The partition and the automatic door enable each drying chamber to be independently set.

[0021] Through the above arrangement, multiple drying chambers are interconnected, so that the temperature and humidity automatic controlled high-efficiency drying structure forms a continuous drying structure. The partitions and automatic doors can enable each drying chamber to be set independently, and the drying conditions of each drying chamber can be set separately, so that the product can complete a drying stage in a drying chamber, enter the next drying chamber through the automatic door, and complete the next drying stage.

[0022] As a further improvement of the above technical solution, the temperature and humidity automatic controlled efficient drying structure includes a track laid along the ground, the track is provided with a drying vehicle for placing products, and the drying vehicle moves into or out of the drying chamber along the track.

[0023] Through the above arrangement, the product is placed on the drying cart, and the drying cart slides precisely along the travel track to enter and exit the drying chamber.

[0024] As a further improvement of the above technical solution, a plurality of cyclone barrels are provided in the drying chamber, and the plurality of cyclone barrels are evenly arranged circumferentially with a vertical axis passing through the center point of the drying chamber as the array center.

[0025] Through the above arrangement, the number of cyclones can be adjusted according to the product requirements or the size of the drying chamber, ensuring that the drying medium discharged by the cyclone can disturb the airflow at various positions in the drying chamber, ensuring that the drying degree of each product is the same. The multiple cyclones are arranged uniformly in the circumference with the vertical axis passing through the center point of the drying chamber as the center of the array, so that each cyclone has the same airflow disturbance range in the drying chamber.

[0026] As a further improvement of the above technical solution, the air outlet is provided with a guide plate for adjusting the air outlet angle.

[0027] Through the above arrangement, the guide plate adjusts the air outlet angle of the drying medium, so that the humid air in the drying chamber can be better discharged into the second air inlet or the exhaust duct. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Reference Figures 1 to 7 , several embodiments of a temperature and humidity automatic control high-efficiency drying structure of the present invention are given below.

[0036] like Figures 1 to 7 As shown, a temperature and humidity automatic control high-efficiency drying structure according to an embodiment of the present invention includes a drying chamber 100, a cyclone 400 and a heating fan 500.

[0037] It is understood that the drying chamber 100 is connected to an exhaust duct 200, and the exhaust duct 200 is used to exhaust the humid air in the drying chamber 100. Figures 1 to 6 When the product is heated and dried, the moisture inside the product evaporates and escapes, thereby increasing the air humidity in the drying chamber 100 . The humid air can be discharged from the drying chamber 100 through the connected exhaust duct 200 to reduce the humidity in the drying chamber 100 .

[0038] It is understandable that a first valve 210 is provided between the exhaust duct 200 and the drying chamber 100, and the first valve 210 is used to control the exhaust amount of the humid air in the drying chamber 100. Figures 1 to 5 When the first valve 210 is in an open state, the humid air in the drying chamber 100 is discharged through the exhaust duct 200, reducing the air humidity in the drying chamber 100. When the first valve 210 is in a closed state, the water evaporated by heating cannot be discharged, and the humidity in the drying chamber 100 remains unchanged.

[0039] It is understood that the cyclone 400 is located in the drying chamber 100. Figure 2 , Figure 4 and Figure 5 The cyclone 400 is a common structure in the art. The cyclone 400 includes a motor and blades. The motor drives the blades to rotate around the central axis of the cyclone 400, so that the air entering the cyclone 400 rotates and is continuously discharged. The drying medium discharged by rotation forms a strong air flow disturbance in the drying chamber 100, so that the products at various positions in the drying chamber 100 can fully contact the drying medium, be evenly heated and dried, and improve the drying consistency of the same batch of products.

[0040] It is understandable that the cyclone 400 is provided with a first air inlet 410, a second air inlet 420 and an air outlet 430. Figure 6 shown.

[0041] It is understandable that the first air inlet 410 is connected to a hot air duct 300, and the hot air duct 300 is used to input hot air into the cyclone 400. The hot air can be supplied by hot smoke discharged from a firing kiln, hot air extracted from other kilns, or hot air generated by a hot air furnace.

[0042] It is understood that the second air inlet 420 is connected to the drying chamber 100 to input the humid air in the drying chamber 100 into the cyclone 400. The humid air generated by the evaporation of the product in the drying chamber 100 humidifies the hot air, so that the humid air in the drying chamber 100 is circulated and utilized as circulating air without the need for additional humidification equipment.

[0043] It can be understood that the air outlet 430 is connected to the drying chamber 100, and the hot air from the first air inlet 410 and the circulating air from the second air inlet 420 are simultaneously input into the cyclone 400, and the cyclone 400 drives the hot air and the wet air to rotate and mix, and the mixed drying medium is discharged into the drying chamber 100 through the air outlet 430 to dry the products in the drying chamber 100.

[0044] It is understandable that the heating fan 500 is located in the cyclone 400. Figure 5 As shown, the heating fan 500 is used to suck the humid air in the drying chamber 100 into the cyclone 400, and can independently control the exhaust wind speed of the mixed drying medium, so as to provide the disturbance intensity of the drying medium according to different products or different drying stages, so as to achieve a suitable convection intensity between the discharged drying medium and the product in the drying chamber 100.

[0045] With such a configuration, the temperature and humidity self-controlled high-efficiency drying structure can dry products with high water content in stages. In the front drying process, close the first valve 210, start the cyclone 400 and the heating fan 500, mix the hot air input from the first air inlet 410 and the humid air from the second air inlet 420, reduce the speed of the heating fan 500, and discharge the drying medium with low wind speed, high temperature and high humidity from the air outlet 430. The high humidity in the drying medium is used to suppress the evaporation of the moisture in the product, so that the high temperature is quickly transmitted to the interior of the entire product, so that the temperature inside and outside the product quickly reaches a uniform state, and the activity of water molecules in the product is increased. Then open the first valve 210, the high-temperature and high-humidity drying medium in the drying chamber 100 is discharged, the air humidity in the drying chamber 100 is reduced, the humidity of the drying medium mixed by the cyclone 400 is reduced, and the moisture in the drying chamber 100 is quickly discharged.

[0046] In the latter drying process, the humidity of the mixed air used for drying gradually decreases, and the rotation speed of the heating fan 500 is increased, so that the air outlet 430 discharges a drying medium with high wind speed, high temperature and low humidity, so that the moisture in the product evaporates quickly, thereby greatly accelerating the evaporation of moisture in high-water content products without affecting the cracking of the dried products, thereby improving the drying efficiency.

[0047] It will be appreciated that staged drying is also suitable for drying products that are difficult to drain.

[0048] It is understandable that a second valve 310 is provided between the hot air duct 300 and the drying chamber 100. Figures 1 to 5 As shown, the hot air input amount of the hot air duct 300 is controlled by the second valve 310. In the front drying process, since the first valve 210 is closed, the high temperature and high humidity air in the drying chamber 100 is circulated, so the opening degree of the second valve 310 is reduced to reduce the input amount of hot air and save heat energy resources.

[0049] In the latter drying process, since the first valve 210 is open, most of the high-temperature and high-humidity air in the drying chamber 100 is discharged through the exhaust duct 200. Therefore, the opening degree of the second valve 310 is increased to increase the input amount of hot air to ensure that the drying medium input into the drying chamber 100 has a high temperature.

[0050] In some embodiments, the second valve 310 is a manually controlled valve, and the opening and closing of the second valve 310 is controlled manually.

[0051] In this embodiment, the second valve 310 is an electric control valve such as a solenoid valve or an electric ball valve. The opening degree of the second valve 310 is adjusted by controlling the motor, making the control of the input amount of hot air more intelligent and simple.

[0052] Furthermore, the temperature and humidity automatic control type efficient drying structure also includes a temperature sensor 710 and a controller that are electrically connected. Specifically, the probe of the temperature sensor 710 is located in the drying chamber 100 to detect the temperature data in the drying chamber 100 and send the acquired temperature data to the controller, such as Figure 1 , Figure 3 , Figure 4 and Figure 7 Different products or different drying stages have different drying temperatures. The controller is electrically connected to the second valve 310. The controller compares the acquired temperature data with the drying temperature corresponding to the product or drying stage, thereby increasing or decreasing the opening degree of the second valve 310 and adjusting the input amount of hot air, so that the temperature in the drying chamber 100 always maintains the drying temperature corresponding to the product or drying stage.

[0053] It is understandable that the temperature sensor 710 may be a thermal resistance sensor, an ultrasonic sensor, etc. In this embodiment, the temperature sensor 710 is a thermocouple sensor.

[0054] In some embodiments, the high-temperature and high-humidity air in the drying chamber 100 automatically flows out along the exhaust duct 200 through the opened first valve 210 , but the outflow speed and efficiency are slow.

[0055] In this embodiment, the temperature and humidity automatic control type high-efficiency drying structure further includes a dehumidification fan 600, which is connected to the exhaust duct 200. The dehumidification fan 600 absorbs the humid air in the drying chamber 100 through negative pressure, thereby accelerating the discharge of moisture in the drying chamber 100. Figure 1 , Figure 3 , Figure 4 and Figure 7 shown.

[0056] It is understandable that the temperature and humidity automatic control type efficient drying structure also includes a humidity sensor 720, such as Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown. Specifically, the humidity sensor 720 is electrically connected to the controller, and the probe of the humidity sensor 720 is located in the drying chamber 100 to detect the relative humidity data in the drying chamber 100 and send the acquired relative humidity data to the controller. Different products or different drying stages correspond to different relative humidity. The controller is electrically connected to the dehumidification fan 600. The controller compares the acquired relative humidity data with the relative humidity corresponding to the product or drying stage, thereby increasing or decreasing the rotation speed of the dehumidification fan 600, adjusting the exhaust volume of the humid air in the drying chamber 100, so that the relative humidity in the drying chamber 100 always maintains the relative humidity corresponding to the product or drying stage.

[0057] It is understandable that the humidity sensor 720 may be a capacitive humidity sensor 720, a resistive humidity sensor 720, an electrolytic humidity sensor 720, etc. In the present embodiment, the humidity sensor 720 is a hygrometer.

[0058] In this embodiment, the drying chamber 100 is a cubic structure, the length direction of the drying chamber 100 is the front-to-back direction, and the width direction of the drying chamber 100 is the left-to-right direction. Figure 1 and Figure 3 The drying chamber 100 may be a drying kiln.

[0059] In this embodiment, the exhaust duct 200 and the hot air duct 300 are both arranged above the drying chamber 100, and the connecting position between the exhaust duct 200 and the drying chamber 100 is arranged at the upper end of the drying chamber 100. Figure 1 and Figure 3 The cyclone 400 is vertically mounted in the drying chamber 100 , the first air inlet 410 is disposed at the upper end of the cyclone 400 , the communicating position of the second air inlet 420 is disposed at the arc surface of the cyclone 400 , and the air outlet 430 is located at the lower end of the second air inlet 420 and disposed at the conical surface of the cyclone 400 .

[0060] It is understood that the drying chamber 100 is provided with a plurality of dehumidification ports 150 for communicating with the exhaust duct 200, such as Figure 6 Each dehumidification port 150 is provided with a first valve 210, and the opening amplitude of the dehumidification port 150 is adjusted by the first valve 210, so as to control the amount of humid air extracted by each dehumidification port 150, so that the amount of humid air extracted by each dehumidification port 150 reaches a balanced state.

[0061] In this embodiment, two dehumidification ports 150 are arranged at intervals on the two long end edges of the upper end of the drying chamber 100, and two exhaust ducts 200 are provided, and one end of each of the two dehumidification ports 150 is extended in the front-to-back direction, so that the two dehumidification ports 150 arranged in the front and back of the drying chamber 100 are connected to one exhaust duct 200, and the dehumidification fan 600 is connected to the two exhaust ducts 200. Therefore, the dehumidification fan 600 can quickly and evenly extract the humid air in various places of the drying chamber 100 through the multiple dehumidification ports 150 connected by the multiple exhaust ducts 200.

[0062] In some embodiments, the first valve 210 is a manually controlled valve, and the opening degree of the first valve 210 is manually adjusted.

[0063] In other embodiments, the first valve 210 is an electric control valve. The plurality of first valves 210 are electrically connected to a controller, and the controller uniformly adjusts the opening degree of the plurality of first valves 210, making the opening and closing of the first valves 210 more convenient and intelligent.

[0064] It is understandable that the controller can be a single chip microcomputer or a PCL controller, which can simply realize the control of the second valve 310 and the dehumidification fan 600. It should be noted that the control method of the controller does not belong to the protection scope of the present invention and belongs to the prior art. The present invention mainly protects the connection method of the controller.

[0065] It is understandable that the drying chamber 100 is provided with an entrance 110 and an exit 120. Specifically, both the entrance 110 and the exit 120 are provided with automatic doors 130, and the automatic doors 130 are electrically connected to the controller. When the product enters the drying chamber 100, the controller automatically closes the automatic door 130, so that the drying chamber 100 is sealed, isolating the internal space of the drying chamber 100 from the external environment, and preventing external environmental factors (such as humidity, temperature, etc.) from affecting the product.

[0066] In some embodiments, the temperature and humidity automatic control type high-efficiency drying structure is used as an intermittent drying room. Specifically, the entrance 110 is the exit 120, the entrance 110 is located at the front end of the drying room 100, the rear end of the drying room 100 is closed, the product enters and exits from the front end of the drying room 100, and the automatic door 130 is located at the front end of the drying room 100. Figure 1 and Figure 2 shown.

[0067] In other embodiments, the temperature and humidity automatic control type high-efficiency drying structure is used as a channel type drying room. Specifically, the entrance 110 and the exit 120 are respectively arranged at the two ends of the drying room 100 along the length direction, that is, the entrance 110 is arranged at the front end of the drying room 100, and the exit 120 is arranged at the rear end of the drying room 100. The product enters the drying room 100 from the front end along the front-to-back direction and is output from the rear end. The automatic door 130 is respectively arranged at the front end and the rear end of the drying room 100.

[0068] It can be understood that when the width of the drying chamber 100 is large, the entrance 110 and the exit 120 of the drying chamber 100 are both provided with multiple automatic doors 130, and the multiple automatic doors 130 at the entrance 110 and the multiple automatic doors 130 at the exit 120 correspond to each other in the front-to-back direction to provide multiple channels for products to enter the drying chamber 100, thereby facilitating the rapid input or output of products.

[0069] In this embodiment, the entrance 110 and the exit 120 are respectively provided with three automatic doors 130 spaced apart in the left-right direction, and the wall of the drying chamber 100 is used to separate two adjacent automatic doors 130 on the left and right.

[0070] Furthermore, the temperature and humidity automatic control type high-efficiency drying structure is used as a channel-type continuous drying room. Specifically, the drying chamber 100 is provided with a plurality of drying chambers 100 and connected in sequence along the length direction to form a continuous drying channel. The product can enter from the entrance 110 located at the front end of the drying chamber 100 and exit from the exit 120 located at the rear end of the drying chamber 100. Figure 3 and Figure 4 shown.

[0071] It is understandable that a partition 140 is provided between two adjacent drying chambers 100. Figure 4 As shown, the closed automatic door 130 and partition 140 enable each drying chamber 100 to be independently set without interfering with each other. Each drying chamber 100 has an independent controller to independently control the temperature, humidity, wind speed, etc. required for the drying stage.

[0072] In some embodiments, multiple controllers corresponding to multiple drying chambers 100 are set in linkage, so that the multiple drying chambers 100 are interconnected and have the same drying progress, and the temperature and humidity automatic control high-efficiency drying structure dries the products in the multiple drying chambers 100 at the same time.

[0073] In this embodiment, multiple controllers corresponding to multiple drying chambers 100 respectively set the temperature, humidity and other conditions required for different drying stages in the front-to-back direction, and each drying chamber 100 is independently set through the automatic door 130 and the partition 140, so that two adjacent drying chambers 100 do not interfere with each other. When drying products, the products pass through different drying chambers 100 from front to back in sequence, and undergo different drying stages respectively.

[0074] For example, when drying products with high water content in stages, the drying chamber 100 located at the front end can be in the front drying process, so that the air outlet 430 discharges the drying medium with low wind speed, high temperature and high humidity; the drying chamber 100 located at the rear end can be in the rear drying process, so that the air outlet 430 discharges the drying medium with high wind speed, high temperature and low humidity. When the product needs to switch the drying stage, the automatic door 130 automatically opens to allow the product to move to the next drying chamber 100. The automatic door 130 automatically closes after the product moves to reduce the mutual influence of the drying media in the two drying chambers 100.

[0075] It is understandable that the number of drying chambers 100 actually required is determined according to factors such as the actual required output of different products and different sites, so as to improve the applicability of the temperature and humidity automatic control type efficient drying structure. In this embodiment, the temperature and humidity automatic control type efficient drying structure includes three drying chambers 100, such as Figure 3 and Figure 4 shown.

[0076] It is understandable that each drying chamber 100 is respectively connected to a hot air duct 300 and an exhaust duct 200. Since the hot air duct 300 is used to supply hot air, the hot air ducts 300 of multiple drying chambers 100 are connected front to back. Since the exhaust duct 200 is connected to the dehumidification fan 600, the controller controls the rotation speed of the dehumidification fan 600, and therefore, the exhaust duct 200 and the dehumidification fan 600 of each drying chamber 100 are independently set.

[0077] It can be understood that the partition member 140 is a partition plate extending up and down.

[0078] It is understandable that the temperature and humidity automatic control type efficient drying structure includes a driving track 800 laid along the ground, such as Figures 1 to 4 The driving track 800 extends along the length direction of the drying chamber 100, that is, the driving track 800 extends along the front-back direction and passes through the drying chamber 100. A drying vehicle 900 for placing products is slidably connected to the driving track 800, and the drying vehicle 900 can enter and exit the drying chamber 100 along the driving track 800.

[0079] In some embodiments, the drying vehicle 900 is pushed and pulled manually so that the drying vehicle 900 can slide accurately along the vehicle track 800 in and out of the drying chamber 100 .

[0080] In other embodiments, the drying vehicle 900 or the vehicle track 800 has a power system (such as electricity, fuel, electromagnetic energy, etc.), which can enable the drying vehicle 900 to automatically move along the vehicle track 800, and the drying vehicle 900 can accurately enter and exit the drying chamber 100 through the limiting effect of the vehicle track 800.

[0081] With such arrangement, it is not necessary for the staff to manually push the drying cart 900 into the drying chamber 100 , thus reducing the labor cost, and the drying cart 900 can automatically enter or exit the drying chamber 100 .

[0082] It can be understood that the drying cart 900 extends in the up and down direction and is provided with a limiting structure for placing multiple products, so that multiple products can be laid on the drying cart 900 at intervals, and the upper and lower spaces are utilized to increase the number of products that can be dried in the drying chamber 100 at a time, thereby improving the drying efficiency of the products.

[0083] It is understandable that the number of driving tracks 800 corresponds to the number of automatic doors 130 at the entrance 110 of the drying chamber 100. That is, each drying chamber 100 is provided with three driving tracks 800 spaced apart in the left and right directions, thereby increasing the drying capacity of the drying chamber 100 and the efficiency of multiple products entering and exiting the drying chamber 100.

[0084] It is understandable that, for a drying chamber 100 with a smaller space, each drying chamber 100 is provided with a cyclone barrel 400 , and one cyclone barrel 400 can satisfy the contact between multiple products in the drying chamber 100 and the drying medium.

[0085] It is understandable that for a drying chamber 100 with a larger space, each drying chamber 100 is provided with a plurality of cyclone drums 400, such as Figures 1 to 5 As shown, the drying media discharged from the plurality of cyclones 400 are fully in contact with the plurality of products in the drying chamber 100, ensuring that each product is dried to the same degree.

[0086] It is understandable that when the drying chamber 100 is provided with a plurality of cyclone barrels 400, the plurality of cyclone barrels 400 are evenly arranged in the drying chamber 100. Specifically, the plurality of cyclone barrels 400 are evenly arranged circumferentially with the vertical axis passing through the center point of the drying chamber 100 as the array center, ensuring that the drying medium discharged from each cyclone barrel 400 has the same airflow disturbance range.

[0087] In this embodiment, two cyclone drums 400 are provided in each drying chamber 100. Figure 2 and Figure 5 The connecting line of the two cyclones 400 is arranged obliquely with respect to the length direction of the drying chamber 100, so that the drying medium discharged from each cyclone 400 has a larger air flow disturbance range in the drying chamber 100.

[0088] It can be understood that the hot air duct 300 is connected to a plurality of cyclone cylinders 400 in a branched manner.

[0089] It is understandable that the air outlet 430 is provided with a guide plate along the conical surface of the cyclone cylinder 400 for adjusting the air outlet angle.

[0090] It can be understood that the temperature and humidity automatic control high-efficiency drying structure can independently, accurately and automatically adjust the temperature and humidity of the drying medium. The circulating air volume and wind speed can also be independently controlled without affecting each other, so that each drying stage of the drying product can be accurately and independently controlled, thereby improving the drying efficiency of bricks and other products and reducing product cracking.

[0091] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
