Description

Technical Field

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

[0002] In modern industrial production, refractory bricks, as an important industrial material, are widely used in high-temperature fields such as metallurgy, building materials, and chemicals. The drying process is crucial in the production of refractory bricks. Refractory bricks are key materials in high-temperature industrial environments, with significant functions. In metallurgical furnaces, their excellent high-temperature resistance prevents high-temperature erosion, ensures the stability of the furnace structure, and maintains the continuous operation of smelting. In high-temperature kilns in building materials production, refractory bricks can effectively insulate heat, reduce heat loss, and lower energy consumption, while also withstanding material impact and high-temperature airflow, ensuring the long-term stable operation of the kiln. In the chemical industry, facing complex chemical substances and high-temperature environments, refractory bricks can resist chemical erosion, providing reliable protection for reaction equipment and facilitating the smooth operation of various chemical production processes.

[0003] Traditional refractory brick drying methods mainly rely on natural air drying or simple drying kilns. Natural air drying is greatly restricted by weather and other natural factors. In rainy weather, the drying cycle will be greatly extended, which will seriously affect the production progress. Simple drying kilns are not only energy-intensive, but also have low drying efficiency, making it difficult to meet the needs of large-scale industrial production. At the same time, due to uneven drying, the internal moisture content of refractory bricks is often inconsistent, which can easily lead to quality problems such as cracking and deformation during subsequent use, reducing the service life and performance stability of refractory bricks. To address these issues, we have proposed a rapid refractory brick drying device. Utility Model Content

[0015] 1. This rapid refractory brick drying equipment greatly improves drying efficiency. Four drying devices work in symmetrical arrangement in two groups to dry the refractory bricks on the roller conveyor from all directions. Hot air is rapidly blown onto the refractory bricks by fans, accelerating moisture evaporation. Simultaneously, the roller conveyor continuously and rapidly feeds the refractory bricks into and out of the drying chamber, achieving continuous production. Compared to natural air drying and simple drying kilns, it significantly shortens the drying cycle, meets the drying efficiency requirements of large-scale industrial production, and effectively improves production progress.

[0016] 2. This rapid refractory brick drying equipment ensures the drying quality of refractory bricks. The hot air blown out by the drying device acts evenly on the refractory bricks, avoiding uneven drying and reducing inconsistent internal moisture content. This lowers the probability of cracking, deformation, and other quality problems during subsequent use. The air filter promptly filters and discharges humid air, ensuring a good drying environment. The funnel and slag outlet are cleaned of debris to prevent it from affecting the drying effect of the refractory bricks. Furthermore, the protective curtain reduces heat loss and stabilizes the drying temperature, allowing the refractory bricks to dry in a stable and suitable environment, thereby improving the quality stability and service life of the refractory bricks.

[0050] Working Principle: Install the refractory brick rapid drying equipment correctly according to the diagram. During operation, first connect the equipment to an external power source. The motor and sprocket of the roller conveyor device 5 drive the conveyor roller 6 to rotate. The refractory bricks pass through the roller conveyor device 5 and enter the drying chamber 1 through the brick inlet / outlet 16 equipped with a protective curtain 4. At this time, the drying devices 2 located on the two opposite side walls of the drying chamber 1 begin to operate. The main body of the drying device 2 is placed inside the chamber 9. The heating element 10 is powered on and heats up. The fan 11 blows the hot air generated by the heating element 10 into the drying chamber 1, ensuring the hot air is evenly distributed. The air is blown onto the surface of the refractory bricks, causing the moisture inside the refractory bricks to quickly vaporize and evaporate. During the drying process, the humid air generated rises and is filtered by the air filter 3 at the center of the top of the drying chamber 1 before being discharged, ensuring the air quality inside the drying chamber 1. At the same time, the funnel 7 at the bottom of the drying chamber 1 collects the debris generated during the drying process. The debris is connected to the external collection equipment through the slag outlet 8 to prevent debris from polluting the environment. Throughout the drying process, the protective curtain 4 effectively reduces heat loss, and together with the frame 13 and the grid 14, ensures the safety of the equipment operation.
