Description

Technical Field

[0001] This utility model relates to the field of ceramics technology, specifically to a drying device. Background Technology

[0002] Pottery is a type of vessel made by shaping clay or earthenware and then firing it. Pottery has a long history, with simple and rough pottery appearing as early as the Neolithic Age. While pottery was used as a daily necessity in ancient times, it is now generally collected as art pieces. The production process of pottery involves making and processing the clay blanks.

[0003] Currently, in the process of processing ceramic blanks, they need to be dried to set their shape. During the drying process, the ceramic blanks are transported and dried via conveyor belts. However, when the ceramic blanks are first transported from the production line to the top of the conveyor belt, they have a certain level of humidity and temperature. If the heating temperature is too low, the ceramic blanks may develop internal stress in subsequent stages due to uneven evaporation of moisture. At the same time, if the heating temperature is too high, the surface of the ceramic blanks may dry and harden rapidly due to rapid evaporation of moisture, while the internal moisture remains, which may lead to the ceramic blanks cracking. Utility Model Content

[0004] The purpose of this invention is to provide a drying device to solve the problem that ceramic blanks may crack during the initial drying stage when they are at a certain temperature and humidity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device, including a conveyor belt, and further comprising:

[0006] An internal through-hole is provided; a first drying box and a second drying box are provided on the outside; and a heating box is provided on the top of the second drying box.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a drying device includes a conveyor belt 1, which transports ceramic blanks that need to be dried under the action of the conveyor belt 1. The device also includes:

[0023] The through-hole 2 inside allows the ceramic blanks inside the first drying box 3 and the second drying box 4 to receive uniform heat. The first drying box 3 and the second drying box 4 on the outside allow the ceramic blanks to be preheated and thoroughly dried. The heating box 5 on the top of the second drying box 4 allows the ceramic blanks inside the second drying box 4 to receive uniform heat.

[0024] The preheating component 6, located at the top of the first drying chamber 3, preheats the ceramic blanks, preventing them from absorbing excessive heat and cracking or breaking. The preheating component 6 includes a preheating box 61 at the top of the first drying chamber 3. Through the PLC controller, the temperature of the heating plate 62 within the preheating box 61 can be controlled. The inner wall of the preheating box 61 is equipped with the heating plate 62. Under the action of the preheating box 61, the air inside the preheating box 61 can be heated. The first drying box 3 is provided with an air outlet plate 63. By setting the air outlet plate 63, the heated air can be transported under the action of the air outlet plate 63. The front surface of the first drying box 3 is fixedly connected with a liquid storage box 64. The first drying box 3 is provided with a conveying pipe 65. The outside of the conveying pipe 65 is connected to an atomizing nozzle 66. By setting the liquid storage box 64, moisture can be stored. Under the action of the conveying pipe 65, the moisture can be atomized at the atomizing nozzle 66 through the conveying pipe 65.

[0025] refer to Figure 2 and Figure 3 As shown, a fan 7 is fixedly connected to the top of the first drying box 3. By setting the fan 7, hot air inside the preheating box 61 can be extracted under the action of the fan 7. A base plate 8 is fixedly connected to the bottom of the fan 7, and the air inlet of the fan 7 is connected to the inside of the preheating box 61.

[0026] The first drying chamber 3 is equipped with a first screw mechanism 9. By setting the first screw mechanism 9, the height of the air outlet plate 63 can be adjusted, thereby adjusting the distance between the ventilation head 10 and the ceramic blank, thus allowing for a small-range adjustment of the heat absorbed by the ceramic blank. The bottom of the air outlet plate 63 is connected to the ventilation head 10, and the air outlet plate 63 is connected to the air outlet of the fan 7. By setting the ventilation head 10, the fan 7 draws air from the preheating box 61 and releases it through the ventilation head 10. The top of the liquid storage box 64 is connected to the delivery pump 11.

[0027] An infrared detector 12 is installed on one side of the first drying oven 3. A temperature sensor 13 and a humidity sensor 14 are respectively installed on the inner wall of the first drying oven 3. By installing the temperature sensor 13 and the humidity sensor 14, the temperature and humidity data inside the first drying oven 3 can be detected and transmitted.

[0028] The inner wall of the second drying chamber 4 is fixedly connected to a gathering box 26. By setting the gathering box 26, the heated air can be concentrated and transported to form high-speed hot air. The bottom of the gathering box 26 is connected to a connecting pipe 15. By setting the connecting pipe 15 and the sliding pipe 16, the sliding pipe 16 and the connecting pipe 15 can remain connected when the first drying plate 17 moves. The bottom of the connecting pipe 15 is connected to the sliding pipe 16, and the inner wall of the sliding pipe 16 is slidably connected to the outer side of the connecting pipe 15.

[0029] refer to Figure 1 and Figure 4 As shown, the bottom of the sliding tube 16 is connected to the first drying plate 17. By setting the first drying plate 17, the ceramic blank can be dried by hot air from top to bottom under the action of the air outlet 21 inside the first drying plate 17. The second drying box 4 is equipped with a second screw mechanism 18. By setting the second screw mechanism 18, the distance between the first drying plate 17 and the ceramic blank can be adjusted. The bottom of the first drying plate 17 is connected to the connecting pipe 19. The end of the connecting pipe 19 away from the first drying plate 17 is connected to the second drying plate 20. By setting the second drying plate 20, the ceramic blank can be dried by hot air from bottom to top under the action of the second drying plate 20. The first drying plate 17 and the second drying plate 20 are provided with air outlet 21 inside.

[0030] The heating box 5 has an air inlet 22 inside and is equipped with electric heating tubes 23. By setting multiple electric heating tubes 23, the air inside the heating box 5 can be heated quickly. A fixing plate 24 is fixedly connected to the bottom of the heating box 5. A rotating fan 25 is set at the bottom of the fixing plate 24. By setting the rotating fan 25, the hot air inside the heating box 5 can flow quickly.

[0031] Working principle: When the operator needs to dry the ceramic blanks, the blanks are first placed on top of the conveyor belt 1. The conveyor belt 1 moves the blanks into the first drying chamber 3. The infrared detector 12 detects the temperature of the blanks and transmits the data to the PLC controller. The PLC controller then activates the heating plate 62, which heats the air inside the preheating box 61. The hot air, driven by the fan 7, enters the exhaust plate 63 and is then ejected through the vent 10, thus performing a top-down preliminary drying process on the ceramic blanks. The humidity sensor 14 and temperature sensor 15 also play a role in this process. Under the action of device 13, the temperature and humidity inside the first drying chamber 3 are detected. When the humidity of the ceramic blank is low and cracking may occur, the conveyor pump 11 is started. Under the action of the conveyor pump 11, the water inside the liquid storage box 64 is extracted and then sprayed out through the atomizing nozzle 66, thereby increasing the humidity of the ceramic blank and preventing it from cracking. After the preheating of the ceramic blank is completed, under the action of the conveyor belt 1, the ceramic blank enters the interior of the second drying chamber 4 for thorough drying. At the same time, the interior of the second drying chamber 4 is also equipped with a humidity sensor 14 and a temperature sensor 13 to facilitate real-time monitoring of the humidity and temperature inside the second drying chamber 4.
