Abstract

The invention discloses a catalytic combustion heating and drying process for domestic ceramic products, and aims to solve the problems that in the prior art, products are prone to cracking, and dried products need to be placed in a storage space; and the next drying operation can be carried out after the previous batch of products are dried and taken out. The catalytic combustion heating and drying process comprises the following steps: 1, feeding air into a filter and an activated carbon adsorption box under the action of attraction of a fan, and filtering the air by the filter to remove impurities in the air; foreign matter molecules in the gas are removed by the activated carbon adsorption box; secondly, an electric heater in the catalytic combustor is started, the temperature of the interior of the catalytic combustor is increased, and catalytic combustion and the like are carried out; according to the catalytic combustion heating and drying process, the catalytic combustion technology is utilized, ceramic products cannot be cracked, continuous production can be achieved, and the dried products directly enter the next procedure.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramic shaping, in particular to a catalytic combustion, heating and drying process for daily-use ceramic products. Background technique [0002] Daily-use ceramic products mainly refer to food-use ceramics, that is, ceramic products such as plates, bowls, cups, saucers, etc., which are produced to meet people's needs for daily life. Ceramic products have the advantages of being easy to wash and keep clean. Porcelain glaze is bright and delicate, and it is easy to wash off after being stained. [0003] The current drying methods of ceramic products mainly include hot air drying and natural air drying. When the natural air drying process is adopted, the products are formed by high-pressure molds and then placed on the storage rack in the workshop to dry naturally. This method has the following defects: 1) Long process drying time: easily affected by the uncertainty of season, temperature, humid...
