Description

Technical Field

[0001] The utility model relates to the technical field of magnesia carbon brick drying equipment, in particular to a drying equipment for producing magnesia carbon bricks. Background Art

[0002] Magnesia carbon bricks are a kind of refractory materials. Because of their strong slag resistance, good thermal shock resistance, low high temperature creep and other characteristics, they are often used in the lining of converters, AC arc furnaces, DC arc furnaces, slag lines of ladles and other parts. Magnesia carbon bricks need to be dried during processing to ensure the structural strength of the finished product. The usual drying method is to use high temperature in a drying kiln. In the prior art, after the drying of magnesia carbon bricks is completed, the kiln cooling method is usually used for cooling, which is inefficient and affects the processing and subsequent transportation of magnesia carbon bricks.

[0003] The patent with announcement number CN217585108U discloses a ladle magnesia carbon brick rapid drying device, which includes a drying kiln body, which is arranged in a transverse direction and has open designs on both sides. The application is provided with a cooling bin body at the rear part of the drying kiln body. After the heated and dried magnesia carbon bricks are pushed out of the drying kiln body, the magnesia carbon bricks can be quickly cooled to room temperature through the air cooling component of the cooling bin body, thereby shortening the cooling and cooling cycle of the magnesia carbon bricks, which is beneficial to shortening the drying cycle of the magnesia carbon bricks. The above scheme solves the cooling problem of the magnesia carbon bricks to a certain extent. However, since the cooling gas is blown vertically from bottom to top, the cooling gas will encounter resistance from multiple layers of magnesia carbon bricks during the rising process, resulting in a significant reduction in the airflow of the cooling airflow reaching the upper part, and there is still a problem of reduced overall cooling efficiency. In addition, the scheme cannot adjust the outlet angle of the cooling airflow according to different temperature conditions in the drying kiln. If the temperature of the magnesia carbon bricks is high and is not below the downshift threshold, direct blowing with a large air volume for cooling can easily lead to cracks in the magnesia carbon brick body, which has an adverse effect on product quality.
