Method for producing large-size thin ceramic bricks by microwave and hot air composite drying

Abstract

The invention relates to a method for producing large-size thin ceramic bricks by microwave and hot air composite drying, and belongs to the technical field of ceramic brick body dehydration production process. The method has the main technical characteristic that: the ceramic brick body is dried by using microwave and hot air respectively. The method comprises the following steps of: putting theceramic brick body with moisture content of 16 to 18 percent into a microwave drying room to perform drying treatment; and allowing the ceramic brick body to enter a hot air drying room to perform microwave forming drying and hot air dying. The method has the advantages of high drying speed, uniform heating and drying, high forming quality of products, high thermal efficiency, balanced thermal stress, time conservation, and capability of making the ceramic brick body uniformly changed during dehydrating and drying by microwave dehydrating and drying at first, and the method also has the advantage of reducing the dehydrating cost of the ceramic brick body by dehydrating and drying the ceramic brick body with the hot air.

Description

1. Technical field [0001] The invention relates to a production method for dehydration and drying of a ceramic brick body, in particular to a production method for drying large-size thin ceramic bricks by combining microwaves and hot air, and belongs to the technical field of dehydration production methods for a ceramic brick body. 2. Background technology [0002] The dehydration and drying of the ceramic tile body before firing is a very important production link, which is very important for improving the quality of the finished ceramic tile, because the ambient temperature and the methods and equipment used for the dehydration and drying of the ceramic tile body are not well mastered. It is easy to produce waste products, which affects the quality and cost of ceramic tile products. At present, the drying methods of ceramic tile body mainly include hot air drying and natural drying. [0003] When making ceramic tiles, a certain amount of water should be added to the clay ...

AI Technical Summary

Problems solved by technology

[0023] The purpose of the present invention is to solve the problem that the existing hot air drying and natural drying methods are dehydration of the ceramic tile body. Since the ceramic tile body is not in the same heating range as the heat source and direction, the thermal stress easily generated by uneven heating will cause the body to crack and deform.
