[0002] Ceramic blank drying trend analysis equipment is an indispensable key piece of equipment in ceramic production. During ceramic manufacturing, the formed blanks contain a large amount of moisture. If subsequent processes are carried out directly, it can easily lead to problems such as deformation and cracking, seriously affecting product quality. Therefore, the role of the drying equipment is to remove moisture from the blanks evenly and stably through scientific drying methods, bringing them to a suitable moisture content for firing. With the development of the ceramic industry, the requirements for drying efficiency and quality are constantly increasing, prompting the continuous optimization and upgrading of drying equipment to meet the needs of efficient, energy-saving, and environmentally friendly production.

[0003] In the existing ceramic blank drying process, the evaporation rate of moisture in different parts of the ceramic blank is often inconsistent, which leads to cracking or deformation of the ceramic blank, low drying efficiency, and waste of ceramic materials. Utility Model Content

Detailed Implementation

[0018] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] The embodiments provided by this utility model are as follows: Figures 1-3 As shown, a ceramic blank drying trend analysis device includes a housing 10, inside which a drying chamber 20 is fixedly installed. Several ventilation holes 30 are densely distributed on the side walls of the drying chamber 20. A variable-speed fan 40 and a heating air box 50 are fixedly installed on the top of the housing 10. The output end of the variable-speed fan 40 is connected to the input end of the heating air box 50. An air inlet pipe 60 is fixedly connected to the input end of the variable-speed fan 40. An air outlet pipe 70 is fixedly connected to the output end of the heating air box 50. The air inlet pipe 60 and the air outlet pipe 70 pass through the top of the housing 10. The air outlet duct 70 extends into the chamber 10 and is connected to the side wall of the drying chamber 20. Several branch air ducts 80 are fixedly connected to the air outlet duct 70. The branch air ducts 80 are arranged vertically and evenly. The branch air ducts 80 surround the drying chamber 20 in the horizontal direction and are connected to the side wall of the drying chamber 20. The air inlet duct 60 is set above the branch air ducts 80. A weighing component 90 and an atomizer 100 are fixedly installed on the lower surface of the inner wall of the chamber 10. Both are set below the drying chamber 20. The weighing component 90 is used to measure the mass of the ceramic blanks in the drying chamber 20.

[0020] During use, the operator places the ceramic blank in the drying chamber 20, starts the device, and the variable-speed fan 40 draws air from the drying chamber 20 into the air inlet duct 60, delivering the air to the heating air box 50. The heating air box 50 heats the air, and the heated air flows along the air outlet duct 70 through the various branch ducts 80 before flowing into the drying chamber 20. By setting up the branch ducts 80, the hot air in the air outlet duct 70 enters the drying chamber 20 evenly at different heights, ensuring a uniform temperature at different locations within the drying chamber 20 and a good drying effect on the ceramic blank. This process ensures a good drying effect. The gas temperature inside the drying chamber 20 continues to rise, and the hot air inside the drying chamber 20 exchanges heat with the ceramic blank, causing the moisture inside the ceramic blank to evaporate, thus realizing the drying process of the ceramic blank. During this process, the atomizer 100 is turned on, and the atomizer 100 introduces water vapor into the drying chamber 20 to prevent the ceramic blank from cracking due to over-drying inside the drying chamber 20. During the drying process of the ceramic blank, the weighing component 90 continuously measures and records the mass change of the ceramic blank. When the mass of the ceramic blank reaches the standard, the drying of the ceramic blank is completed, and the staff takes out the dried ceramic blank.

[0021] Preferably, the input end of the speed-regulating fan 40 is fixedly connected to a first reversing air valve 120. Two air inlet pipes 60 are provided, respectively located on the left and right sides of the first reversing air valve 120 and fixedly connected to it. The output end of the heating air box 50 is fixedly connected to a second reversing air valve 130. Two air outlet pipes 70 are provided, respectively located on the left and right sides of the second reversing air valve 130 and fixedly connected to it. In use, the ventilation paths of the first reversing air valve 120 and the second reversing air valve 130 are staggered. When air in the drying chamber 20 flows in from the left air inlet pipe 60, the air output from the heating air box 50 flows out from the right air outlet pipe 70. This arrangement causes the hot air in the drying chamber 20 to flow from bottom to top in a diagonal direction within the drying chamber 20, increasing the contact between the flowing hot air and the surface of the ceramic blank, improving the drying effect of the device, and resulting in high working efficiency.

[0022] Preferably, a support frame 190 is horizontally fixed inside the chamber 10, and the drying chamber 20 is fixedly mounted on the support frame 190. The support frame 190 can improve the stability of the drying chamber 20 and prevent the drying chamber 20 from shaking, which would affect the monitoring effect of various measurement parameters of the ceramic blank.

[0023] Preferably, a plurality of air inlets 200 are evenly provided on the left and right side walls of the housing 10. The air inlets 200 are located below the support frame 190. Providing air inlets 200 can increase the airflow inside and outside the housing 10, facilitate the atomizer 100 to absorb gas, and ensure the balance of air pressure inside and outside the housing 10.

[0024] Preferably, several distance sensors 110 are fixedly installed on the left and right side walls of the chamber 10. The distance sensors 110 are used to measure the deformation of the ceramic blank before and after drying in the drying chamber 20. A temperature and humidity sensor is fixedly installed in the chamber 10. During the drying process of the ceramic blank, the distance sensors 110 are used to continuously measure and record the deformation of the outer surface of the ceramic blank, and the temperature and humidity sensor is used to continuously monitor the temperature and humidity in the drying chamber 20, thereby controlling the opening and closing of the speed-regulating fan 40, the heating air box 50 and the atomizer 100.

[0025] Preferably, rolling wheels 210 are fixedly installed at the four corners of the bottom of the chamber 10 to facilitate the movement of the drying device by the staff and make the operation more labor-saving.

[0026] The working principle of this embodiment, and its more specific process, are as follows:

[0027] The operator places the ceramic blanks into the drying chamber 20 and starts the device. The variable-speed fan 40 draws air from the drying chamber 20 into the air inlet duct 60 and delivers it to the heating air box 50. The heating air box 50 heats the air, and the heated air flows through the outlet duct 70 and then through the branch ducts 80 before flowing into the drying chamber 20. By setting up the branch ducts 80, the hot air in the outlet duct 70 enters the drying chamber 20 at different heights, ensuring a uniform temperature at different locations within the drying chamber 20 and good drying effect for the ceramic blanks. Through this method, the gas temperature inside the drying chamber 20 continuously rises. During this process, the ventilation paths of the first reversing air valve 120 and the second reversing air valve 130 are opened alternately. When air enters the drying chamber 20 from the left air inlet duct 60, the air output from the heating air box 50 flows out from the right air outlet duct 70, and vice versa. Through this method, the hot air inside the drying chamber 20 continuously flows and exchanges heat with the ceramic blanks. The process of drying ceramic blanks involves evaporating moisture from the blanks. During this process, the atomizer 100 is activated, introducing water vapor into the drying chamber 20 to prevent over-drying and cracking of the ceramic blanks. During the drying process, the weighing component 90 continuously measures and records the mass change of the ceramic blanks, the distance sensor 110 continuously measures and records the deformation of the outer surface of the ceramic blanks, and the temperature and humidity sensor continuously monitors the temperature and humidity inside the drying chamber 20. Based on this, the speed-regulating fan 40, the heating box 50, and the atomizer 100 are controlled to open and close. When the mass of the ceramic blanks reaches the standard, the drying process is complete, and the dried ceramic blanks are removed. Furthermore, the operator can plot a data change curve based on the data continuously recorded by the weighing component 90, the distance sensor 110, and the temperature and humidity sensor, and then adjust the working status of each component accordingly to improve the drying efficiency of the ceramic blanks.

[0028] This utility model's ceramic blank drying trend analysis device has a speed-regulating fan 40 and a heating air box 50 fixedly installed on the top of the box 10. The input end of the speed-regulating fan 40 is fixedly connected to an air inlet pipe 60, and the output end of the heating air box 50 is fixedly connected to an air outlet pipe 70. Several branch air pipes 80 are fixedly connected to the air outlet pipe 70. The branch air pipes 80 are vertically and evenly arranged and surround the drying box 20 in the horizontal direction and are connected to the side wall of the drying box 20. The air inlet pipe 60 is located above the branch air pipes 80, so that the temperature at different heights in the drying box 20 of the ceramic blank drying trend analysis device is uniform. This avoids defects such as cracking and deformation of the ceramic blank due to inconsistent moisture evaporation rates at different positions of the ceramic blank, improves the drying efficiency of the device, and saves material costs.
