[0021] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0022] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0023] like Figures 1-4As shown, a drying chamber for ceramic tile production according to this application includes an inlet 1, a heating chamber 2, a ventilation guide plate 3, a temperature sensor 4, an exhaust fan 5, and an outlet 6. The inlet 1 is used to introduce undried ceramic tiles into the drying chamber and is connected to the inlet of the heating chamber 2 to ensure the ceramic tiles can smoothly enter the drying process. The heating chamber 2 is the main structural part of the drying chamber, with multiple independent temperature control zones to achieve temperature adjustment within different ranges, improving drying efficiency and product quality. The ventilation guide plate 3 is located inside the heating chamber 2. Through a reasonable plate distribution design, it can effectively guide the airflow direction, making the heat distribution more uniform and reducing the occurrence of local high or low temperature areas. The temperature sensor 4 is installed at different positions in the heating chamber 2, enabling real-time acquisition of temperature changes in each area and providing feedback information to the control system to ensure the temperature remains within the preset range. The exhaust fan 5 is connected to the heating chamber 2, and its main function is to exhaust the moisture generated during the drying process, maintaining the dryness of the indoor air and preventing humid air from affecting the drying effect. The discharge port 6 is located at the end of the heating chamber 2. The dried ceramic tiles are taken out through this outlet for subsequent processing or packaging.

[0024] The connection between the feed inlet 1 and the heating chamber 2 adopts a detachable or sealed interface design for easy maintenance and cleaning. The heating chamber 2 consists of three insulation layers: a first insulation layer 21, a second insulation layer 22, and a third insulation layer 23. The first insulation layer 21 is located on the outside of the heating chamber 2 to isolate heat exchange with the external environment, reduce energy consumption, and prevent external heat from interfering with the temperature control within the chamber. The second insulation layer 22 is located near the feed inlet 1 to help control the initial temperature rise of the material entering the drying chamber, preventing deformation or cracking of the ceramic tiles due to sudden temperature increases. The third insulation layer 23 is located near the discharge outlet 6 to buffer the heat distribution in the final stage, ensuring good physical stability of the dried product. A first heating tube assembly 24 is provided between the first insulation layer 21 and the second insulation layer 22. This heating tube assembly can be started and stopped individually or as a whole as needed to adapt to the temperature requirements of different process stages. A second heating tube assembly 25 is provided between the second insulation layer 22 and the third insulation layer 23. By zoning, different temperature gradients are achieved to meet the drying requirements of ceramic tiles with different thicknesses or water absorption rates. The first heating tube assembly 24 and the second heating tube assembly 25 are respectively arranged adjacent to their respective ventilation guide plates 3, thereby ensuring that the heat emitted by the heating elements can be quickly and evenly diffused to the entire drying area with the assistance of the guide plates.

[0025] This application effectively achieves precise zoned control of the temperature gradient within the drying chamber by dividing the heating cavity 2 into multiple segmented, independently temperature-controlled zones and incorporating a multi-layered insulation structure. By monitoring and receiving feedback data from temperature sensors 4 in each zone, the control system can automatically adjust the heating intensity and ventilation volume of each zone according to actual needs. Combined with the design of the ventilation guide plate 3, not only is airflow organization optimized, but heat transfer efficiency is further improved, ensuring that the temperature of each zone remains stable near the target value. Furthermore, the first heating tube group 24 and the second heating tube group 25 are used in conjunction with the corresponding guide plates, making heat delivery more precise, forming a reasonable temperature gradient, and avoiding heat accumulation or insufficient heat. This ensures that the ceramic tiles receive effective dehydration treatment at different drying stages, improving product quality and consistency.

[0026] like Figure 3 As shown, in one embodiment, the ventilation guide plate 3 of the drying chamber for ceramic tile production according to this application is composed of multiple adjustable-angle arc-shaped plates spliced ​​together. Each arc-shaped plate is connected to the inner wall of the heating chamber 2 via a hinge 31. This structure allows each arc-shaped plate to adjust its tilt angle according to actual needs, thereby changing the airflow path inside the heating chamber 2. By flexibly adjusting the angle of the arc-shaped plates, the uniformity of hot air distribution within the chamber can be effectively improved, drying efficiency can be increased, and problems of excessively high or low local temperatures can be avoided. This adjustable guide plate design helps to improve the equipment's adaptability to ceramic tiles of different specifications.

[0027] Specifically, each arc-shaped plate of the ventilation guide plate 3 is connected to the inner wall of the heating cavity 2 via a hinge 31, and the hinge 31 is located at the bottom edge of the arc-shaped plate, allowing the arc-shaped plate to be rotated and adjusted around this axis. The arc-shaped plates are assembled in a splicing manner to form a continuous airflow guiding channel, ensuring that the gas can flow smoothly in the set direction, while also facilitating the maintenance and replacement of some components.

[0028] like Figure 3 As shown, in one embodiment, the temperature sensor 4 for a drying chamber in ceramic tile production according to this application includes multiple uniformly distributed infrared temperature probes 41. Each infrared temperature probe 41 is installed in the middle of different segmented independent temperature control zones within the heating chamber 2. By arranging multiple infrared temperature probes 41 in their respective independent temperature control zones, accurate acquisition and real-time monitoring of the temperature in each zone can be achieved. This arrangement avoids blind spots in temperature monitoring and improves the accuracy and response speed of temperature control during the drying process. Simultaneously, the infrared temperature probes 41, installed in the middle of the zone, can effectively reflect the average temperature state within the zone, ensuring the stability of the drying process.

[0029] Specifically, multiple infrared temperature probes 41 of the temperature sensor 4 are fixed on the inner wall of the heating cavity 2. The installation position of each probe corresponds to the partition structure of its area and they are evenly arranged along the length of the heating cavity 2. The detection end of the probe faces the internal airflow channel to ensure sensitive capture of hot air temperature, while its signal output end is connected to the control system for easy data acquisition and feedback adjustment.

[0030] like Figures 1-3 As shown, in one embodiment, the dehumidification fan 5 of the drying chamber for ceramic tile production according to this application is equipped with an adjustable fan speed module 51. This module is connected to a temperature sensor 4 and dynamically adjusts the fan speed by monitoring humidity changes. This structure can flexibly control the dehumidification rate under different humidity conditions, improving drying efficiency and energy consumption control accuracy. The temperature sensor 4 is installed at multiple locations within the heating chamber 2 to collect air humidity data in real time and transmit the signal to the adjustable fan speed module 51 to adjust the working intensity of the dehumidification fan 5, thereby maintaining stable humidity in the drying chamber and improving product quality and production consistency.

[0031] For example, the adjustable fan speed module 51 is located at the motor drive end of the dehumidifying fan 5. It receives feedback signals from the temperature sensor 4 through the motor controller and adjusts the motor speed according to the humidity value. The air inlet of the dehumidifying fan 5 is connected to the ventilation channel at the top of the heating chamber 2, and its air outlet is connected to the external exhaust system to ensure that humid air can be efficiently discharged. The temperature sensor 4 is embedded inside the side wall of the heating chamber 2, close to the ventilation guide plate 3, to ensure accurate capture of local humidity changes, enabling the system to achieve rapid response and stable control.

[0032] like Figure 2 As shown, in one embodiment, the first insulation layer 21 of the drying chamber for ceramic tile production according to this application is a vacuum insulation board structure with an internal support frame 211 to enhance structural strength and maintain the integrity of the vacuum insulation board. This structure can effectively reduce heat conduction and prevent heat loss, thereby improving the energy utilization efficiency of the drying chamber. Simultaneously, the first insulation layer 21 is covered with an anti-rust coating 212 to prevent corrosion of metal components due to long-term exposure to humid or high-temperature environments, extending the service life of the equipment. This structure is located outside the heating chamber 2, and a first heating tube assembly 24 is disposed between it and the second insulation layer 22.

[0033] For example, the first insulation layer 21 is connected to the outer shell of the heating chamber 2 by welding or bolting. Its internal support frame 211 is made of metal and is evenly distributed inside the vacuum insulation plate to ensure its mechanical stability. The external anti-rust coating 212 is applied to the surface of the insulation plate by spraying or electroplating to give it good corrosion resistance. This structure is installed on the outer wall of the heating chamber 2 to isolate heat exchange with the external environment.

[0034] In one embodiment, a second insulation layer 22 of the drying chamber for ceramic tile production is disposed inside the heating cavity 2 near the feed inlet 1 to achieve good heat retention. The second insulation layer 22 is made of high-density rock wool, which effectively reduces the rate of heat conduction outwards. The thickness of this layer is designed to be five times that of the third insulation layer 23. By adjusting the thickness ratio of the insulation structure in each area, the uniformity and stability of the temperature field during the drying process are improved. The second insulation layer 22, together with the first insulation layer 21 and the third insulation layer 23, constitute the overall insulation system of the heating cavity 2, ensuring the energy efficiency and safety of the equipment under different operating conditions.

[0035] For example, the second insulation layer 22 is installed by directly laying it on the inner wall of the heating cavity 2. Its internal structure is made of high-density rock wool boards stacked together, and it maintains a certain distance from the first heating tube group 24 and the ventilation guide plate 3 to ensure effective heat transfer. The lower surface of the second insulation layer 22 is tightly attached to the inner side of the first insulation layer 21, while the upper surface is adjacent to the second heating tube group 25, thereby forming an effective heat conduction path and avoiding local structural damage caused by overheating.

[0036] like Figure 2 As shown, in one embodiment, the third insulation layer 23 of the drying chamber for ceramic tile production of this application is provided with ventilation channels 231. The ventilation channels 231 and the discharge port 6 form a local circulation channel, improving the heat utilization rate of the discharge area. This design optimizes the structure of the third insulation layer 23 by setting a through ventilation channel 231 near the discharge area, allowing some hot air to circulate in the discharge area, improving the heat utilization efficiency of this area and reducing heat waste. The arrangement of the ventilation channels 231 not only effectively guides the direction of hot air flow but also maintains the stability of temperature distribution, thereby improving the quality consistency of ceramic tiles during the drying process.

[0037] Specifically, the third insulation layer 23 is made of a porous material, with multiple longitudinal or transverse ventilation channels 231 evenly distributed inside. One end of these channels is connected to the discharge port 6, and the other end is connected to the airflow channel inside the heating chamber 2, so that hot air can be recirculated through a fan or natural convection. The ventilation channels and the discharge port 6 can be connected by an embedded or spliced ​​connection to ensure unobstructed airflow.

[0038] like Figure 2 and Figure 4As shown, in one embodiment, the first heating tube group 24 and the second heating tube group 25 of the drying chamber for ceramic tile production of this application are both serpentine-arranged resistance heating tubes, respectively embedded between corresponding insulation layers and fixed by a fixing bracket 241. This structure effectively achieves concentrated heat distribution by arranging the heating tubes between the insulation layers, while ensuring the uniformity and stability of the heating process. The serpentine arrangement helps to increase the contact area between the heating tubes and the airflow, improving heat transfer efficiency. The first heating tube group 24 is located between the first insulation layer 21 and the second insulation layer 22, while the second heating tube group 25 is located between the second insulation layer 22 and the third insulation layer 23, allowing the heating power of each area to be independently controlled as needed, thus improving the drying effect.

[0039] For example, the serpentine heating tubes of the first heating tube group 24 and the second heating tube group 25 are first laid in the cavity between the insulation layers according to the design requirements. Then, the heating tubes are firmly fixed between the insulation layers by the fixing bracket 241 to ensure that their position is stable and does not shift, while avoiding direct contact with the insulation material to prevent local overheating or damage. The two ends of the heating tubes are connected to power lines and work in conjunction with the temperature sensor 4 to realize the coordinated operation of the temperature control system.

[0040] like Figure 2 and Figure 4 As shown, in one embodiment, a heat exchange fin 242 is provided between the first heating tube assembly 24 and the ventilation guide plate 3 in the drying chamber for ceramic tile production according to this application. The heat exchange fin 242 is installed in the space between the heating tube assembly and the ventilation guide plate 3 to improve heat conduction efficiency. The heat exchange fin 242 is connected to the surface of the heating tube assembly by a fixed structure and maintains a certain distance from the ventilation guide plate 3, thereby optimizing the heat diffusion path in the air and improving heat transfer efficiency. The heat exchange fin 242 can be made of a metal material with good thermal conductivity, which can effectively enhance the heat exchange effect between the heating tube assembly and the airflow and avoid heat waste.

[0041] Specifically, heat exchange fins 242 are disposed between the first heating tube assembly 24 and the adjacent ventilation guide plate 3. The installation method involves fixing one end of the fin to the surface of the heating tube assembly and extending the other end close to the ventilation guide plate 3, forming an angle or parallel arrangement with the ventilation guide plate 3 to increase the contact area and improve heat exchange efficiency. This structure makes it easier for the heat emitted by the heating tube assembly to be carried away by the airflow, improving the overall heating efficiency of the drying chamber.

[0042] like Figure 2 and Figure 4As shown, in one embodiment, a baffle plate 251 is provided between the second heating tube assembly 25 and the ventilation guide plate 3 in the drying chamber for ceramic tile production, to prevent high-temperature airflow from directly impacting the surface of the ceramic tile. The baffle plate 251 is installed in the area between the second heating tube assembly 25 and the ventilation guide plate 3, positioned between the side of the heating chamber 2 closest to the inlet 1 and the side closest to the outlet 6. The baffle plate 251 acts as a barrier, allowing the heated airflow to be mixed and buffered before entering the ventilation guide plate 3, preventing localized overheating that could cause cracks or deformation on the ceramic tile surface. Through a reasonable installation method, this structure can effectively improve the stability of the drying process and the yield rate.

[0043] Specifically, the baffle plate 251 is fixed horizontally inside the heating cavity 2, with one end connected to the outer wall of the second heating tube group 25 and the other end close to the edge area of ​​the ventilation guide plate 3, forming an arc-shaped or inclined shielding structure to ensure that the airflow is evenly distributed above the baffle plate 251 before entering the ventilation guide plate 3, thereby achieving effective guidance and control of the airflow path.

[0044] like Figure 4 As shown, in one embodiment, the heating chamber 2 of a drying chamber for ceramic tile production according to this application is equipped with a sliding partition 7 to adjust the size of each segmented, independently temperature-controlled zone. The sliding partition 7, by moving along the length of the heating chamber 2, can flexibly divide the internal space of the heating chamber 2, thereby meeting the temperature control requirements during different stages of ceramic tile drying. An adjustable enclosed space is formed between the sliding partition 7 and the wall of the heating chamber 2, allowing the heating and ventilation systems of each zone to operate independently. This structural design helps to improve drying efficiency and temperature uniformity.

[0045] Specifically, the sliding partition 7 is positioned and moved by a guide rail mechanism. The guide rail is installed on the inner surface of the heating chamber 2, and the bottom of the partition has a groove that mates with the guide rail, allowing the partition to slide smoothly within the heating chamber 2. Sealing strips 71 are installed between the two ends of the partition and the side walls of the heating chamber 2 to reduce airflow leakage and ensure the independence of each temperature control zone. The sliding partition 7 is position-adjusted via a manual or electric drive device. The drive device is fixed to the outside of the heating chamber 2 and connected to the partition via a transmission rod.

[0046] like Figure 4As shown, in one embodiment, the sliding partition 7 of the drying chamber for ceramic tile production of this application is provided with sealing strips 71 on both sides to prevent leakage of high-temperature airflow between different drying zones, thereby improving the accuracy of zone control. The sealing strips 71 are located on the side of the sliding partition 7, forming a tight fit with the sliding partition 7. Through this design, the flow path of high-temperature airflow can be effectively blocked, avoiding heat loss and temperature cross-interference between zones, ensuring the functional realization of each segment's independent temperature control zone, and improving the overall drying efficiency and product quality consistency.

[0047] Specifically, the sealing strip 71 is made of high-temperature resistant elastic material, installed on the longitudinal edge of the sliding partition 7, and fixed to the partition by adhesive or snap-fit, so that when the sliding partition 7 moves, the sealing strip 71 can move synchronously with it and maintain close contact with the adjacent wall surface, ensuring a stable and reliable sealing effect of the airflow channel.

[0048] In actual operation, when this device is used, ceramic tiles are fed into the heating chamber 2 through the feed inlet 1. The heating chamber 2 is equipped with multiple segmented independent temperature control zones. The ventilation guide plate 3 guides the airflow to optimize the temperature distribution. The temperature sensor 4 monitors the temperature of each zone in real time. The dehumidifying fan 5 discharges humid air. The dried ceramic tiles are output from the discharge port 6. The heating chamber 2 is equipped with a first heat insulation layer 21 on the outside, a second heat insulation layer 22 on the side near the feed inlet 1, and a third heat insulation layer 23 on the side near the discharge port 6. A first heating tube group 24 is set between the first heat insulation layer 21 and the second heat insulation layer 22, and a second heating tube group 25 is set between the second heat insulation layer 22 and the third heat insulation layer 23. The heating tube groups cooperate with the adjacent ventilation guide plates 3 to achieve efficient and uniform drying of the ceramic tiles.

[0049] The specific embodiments described above further illustrate the purpose, technical solutions, and beneficial effects of the embodiments of this disclosure. It should be understood that the above descriptions are merely specific embodiments of the embodiments of this disclosure and are not intended to limit the scope of protection of the embodiments of this disclosure.
