Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tile processing, and particularly relates to a ceramic tile drying device. Background Art

[0002] The drying of green ceramic tiles is one of the important links in their manufacturing process. A green tile refers to a tile blank that has been formed but not yet fired and contains a high moisture content. To ensure the quality of subsequent firing and the stability of the finished product, most of the moisture must be removed through drying before firing. Drying can not only reduce the moisture content but also enhance the mechanical strength of the green tile and reduce the breakage rate during handling. In addition, uniform drying can avoid firing defects caused by uneven moisture, such as deformation or cracking. In modern ceramic industry, tunnel-type, chain-type or mesh-belt dryers are usually used for efficient artificial drying. These devices can accelerate the drying process by controlling temperature, humidity and air flow, and can adjust the drying parameters according to specific requirements to ensure product quality.

[0003] The structure of the existing green ceramic tile drying device is relatively simple. The water vapor generated during use quickly condenses after drying is completed, resulting in water droplets remaining on the surface of the ceramic tile, making the drying effect of the ceramic tile poor and easily leading to unqualified quality of the produced ceramic tiles. Summary of the Utility Model

[0004] The utility model aims to provide a ceramic tile drying device to solve the problem that water droplets remain on the surface of the existing green ceramic tiles after drying.

[0005] A ceramic tile drying device in this solution includes a conveyor belt. A drying box is arranged outside the conveyor belt. The drying box is provided with a feeding end and a discharging end. Strip-shaped air inlets are evenly distributed at a position close to the feeding end inside the drying box. The air inlets are communicated with a hot air dryer. A plurality of air outlets are evenly distributed at the top of the drying box. The air outlets are connected with an exhaust fan. Hot air generators are evenly distributed at a position close to the discharging end of the drying box.

[0006] Working principle and beneficial effects of this solution: During use, the pressed tiles enter from the feed end of the drying oven along with the transportation of the conveyor belt. Hot air is blown out from the hot air dryer, and the hot air blows to the bottom surface of the tiles along the air inlet, promoting the rapid evaporation of moisture. The water vapor generated by drying moves upward and is discharged by the exhaust fan along with the air outlet after moving upward, enabling the rapid discharge of moisture and promoting drying. It can prevent the condensation of water vapor to form water droplets and remain on the surface of the tiles. As the conveyor belt moves, the tiles move to the position of the hot air generator. Common hot air generators include heating elements, blowers, temperature control systems, and air filters. The heating element heats the air, and the blower is used to push the air through the heating element and then convey the heated air to the designated position. The temperature control system is used to adjust the temperature of the output air. At this time, the green embryo is no longer dried, and the hot air generator continuously blows air on the tiles to gradually reduce the temperature of the green embryo, preventing the green embryo from suddenly being exposed to the normal temperature environment after exiting the drying oven, where the temperature difference is large, resulting in the rapid condensation of water vapor on the surface into water droplets. In this solution, an air supply port is provided at the bottom of the drying oven to convey hot air to the green embryo. During the upward movement of the hot air, it can evenly contact the green embryo and carry away moisture. A top exhaust port is provided inside the drying oven. Utilizing the upward trend of the hot gas, the humid hot gas is extracted from above to promote the drying process. Finally, the drying is stopped, and the hot air generator continuously cools the green embryo, enabling the green embryo to gradually cool down, preventing the green embryo from suddenly being exposed to the normal temperature state, where the temperature drops rapidly, causing the condensation of water vapor into water droplets and remaining on the green embryo. Before the green embryo is exposed to the normal temperature environment, the green embryo is gradually cooled down, which can reduce the formation of water droplets.

[0007] Further, the inner wall of the drying oven is annularly provided with threaded grooves. The threaded grooves can distribute the hot air more evenly and play a role in guiding the hot air.

[0008] Further, a plurality of the air outlets are connected with a centralized exhaust pipe. The centralized exhaust pipe connects each air outlet, and the centralized exhaust pipe is communicated with the air inlet of the exhaust fan. This setting can exhaust air centrally.

[0009] Further, a plurality of the hot air generators are horizontally distributed and surround the conveyor belt. The temperature of the hot air generators gradually decreases from the end close to the feed end to the discharge end. By adjusting the temperature of each hot air generator through the temperature control system in the hot air generator, the temperature of the hot air generators gradually decreases from the end close to the feed end to the discharge end. In this way, the temperature of the green embryo can be gradually reduced, preventing the formation of water droplets due to sudden temperature drop.

[0010] Further, the air outlet of the hot air generator is inclined towards the middle of the drying oven. This setting can make the blown air face the inside of the drying oven, gradually reduce the temperature of the green embryo, and is conducive to blowing the hot air towards the middle of the drying oven, facilitating the exhaust fan to discharge the hot air.

[0012] Figure 2 is Figure 1 the top view of the centralized exhaust pipe in Specific embodiments

[0013] The following is a more detailed description through specific embodiments:

[0014] The reference numerals in the attached drawings of the specification include: drying box 1, feeding end 2, discharging end 3, conveyor belt 4, hot air dryer 5, air inlet 6, air outlet 7, centralized exhaust pipe 8, exhaust fan 9, thread groove 10, hot air generator 11.

[0015] The embodiment is basically as shown in the attached Figure 1 and Figure 2 figures: A tile drying device includes a conveyor belt 4. A drying box 1 is provided outside the conveyor belt 4. The drying box 1 includes a drying section and a cooling section. A thread groove 10 is annularly provided on the inner wall of the drying section in the drying box 1. The drying box 1 is provided with a feeding end 2 and a discharging end 3. Strip-shaped air inlets 6 are evenly distributed at the bottom of the inner wall of the drying section in the drying box 1. The air inlets 6 are communicated with a hot air dryer 5. A plurality of air outlets 7 are evenly distributed at the top of the inner wall of the drying section in the drying box 1. The plurality of air outlets 7 are connected to a centralized exhaust pipe 8. The centralized exhaust pipe 8 is connected to each air outlet 7. The centralized exhaust pipe 8 is communicated with an exhaust fan 9. Hot air generators 11 are evenly distributed on the inner wall of the cooling section in the drying box 1. The plurality of hot air generators 11 are horizontally distributed and surround the conveyor belt 4. The temperature of the hot air generators 11 gradually decreases from the end close to the feeding end 2 to the discharging end 3. The air outlets 7 of the hot air generators 11 are inclined towards the middle of the drying box 1.

[0016] During use, the pressed tiles enter from the feeding end 2 of the drying oven 1 along with the transportation of the conveyor belt 4. Hot air is blown out from the hot air dryer 5. The hot air is blown onto the bottom surface of the tiles through the air inlet 6, promoting the rapid evaporation of moisture. The water vapor generated by drying moves upward. The threaded grooves 10 can distribute the hot air more evenly and play a role in guiding the hot air. After moving upward, it is discharged by the exhaust fan 9 through the air outlet 7. The centralized exhaust pipe 8 realizes centralized exhaust, enabling the rapid discharge of moisture and promoting drying. It can prevent the condensation of water vapor to form water droplets and remain on the surface of the tiles. As the conveyor belt 4 moves, the tiles move to the position of the hot air generator 11. A common hot air generator 11 includes a heating element, a blower, a temperature control system, and an air filter. The heating element heats the air, and the blower is used to push the air through the heating element and then convey the heated air to the designated position. The temperature of each hot air generator 11 is adjusted through the temperature control system in the hot air generator 11, so that the temperature of the hot air generator 11 gradually decreases from near the feeding end 2 to the discharging end 3. At this time, the green embryo is no longer dried, so that the temperature of the green embryo can be gradually reduced, avoiding the formation of water droplets due to a sudden drop in temperature. By continuously blowing air on the tiles with the hot air generator 11, the temperature of the green embryo is gradually reduced, preventing the green embryo from suddenly being exposed to the normal temperature environment after exiting the drying oven 1, where the temperature difference is large, resulting in the rapid condensation of water vapor on the surface into water droplets. In addition, the air blown out by the hot air generator 11 is directed towards the inside of the drying oven 1, gradually reducing the temperature of the green embryo and facilitating the exhaust fan 9 to discharge the hot air towards the middle of the drying oven 1. In the device of this solution, an air supply port is arranged at the bottom of the drying oven 1 to convey hot air to the green embryo. During the upward movement of the hot air, it can evenly contact the green embryo and carry away moisture. A top exhaust port is arranged inside the drying oven 1. Utilizing the upward trend of the hot gas, the humid hot gas is extracted from above to promote the drying process. Finally, the drying is stopped, and the hot air generator 11 is used to continuously cool the green embryo, enabling the green embryo to gradually cool down, preventing the green embryo from suddenly being exposed to the normal temperature state and the temperature dropping sharply, resulting in the condensation of water vapor into water droplets and remaining on the green embryo. Before the green embryo is exposed to the normal temperature environment, the temperature of the green embryo is gradually reduced, which can reduce the formation of water droplets.
