Fritted porcelain forming baking oven

Abstract

A fritted porcelain forming baking oven comprises an oven body made of heat insulating materials, an air heating device arranged on the outer top surface of the oven body, two heat radiation cavities symmetrically distributed on a bottom plate inside the oven body, and a recycling cavity arranged in the middle of a top plate inside the oven body. Heat radiation holes are formed in the surfaces of the heat radiation cavities. Recycling holes are formed in the surface of the recycling cavity. The air heating device comprises a primary heating cavity, a heating electric wire arranged in a wall of the primary heating cavity, an exhaust fan and a secondary heating cavity, wherein the exhaust fan is communicated with the primary heating cavity through the secondary heating cavity; the heat radiation cavities are communicated with the exhaust fan through heat radiation pipes; the recycling cavity is communicated with the primary heating cavity through a recycling pipe; a plurality of metal rods are embedded in the wall of a cavity body of the secondary heating cavity; one end of each of the metal rods extends into the secondary heating cavity, and the other end of each of the metal rods is located outside the secondary heating cavity; the diameter of the heat radiation pipes is larger than that of the recycling pipe. The fritted porcelain forming baking oven has the advantages of being simple in structure, carrying out baking in a hot air circulating heating mode, and being high in baking efficiency.

Description

technical field [0001] The invention relates to soft porcelain production equipment, in particular to a soft porcelain molding and baking box. Background technique [0002] Soft porcelain is not real porcelain, nor tiles, it is a new type of building decoration material. According to the "Technical Regulations for Soft Porcelain Architectural Decoration Engineering" formulated by Guangdong Province: Modified clay (MCM) is used as the main raw material, and a special temperature-controlled molding system is used to form, bake, and irradiate cross-linked. architectural decorative surface materials. [0003] The production method of soft porcelain includes first preparing soft porcelain particles, then spreading the prepared soft porcelain particles in the mold, and then heating and drying to make it. The baking volume of the traditional baking box is not large, and each time only The amount of baking is not large, which seriously affects the production efficiency. Simply inc...

Problems solved by technology

[0003] The production method of soft porcelain includes first preparing soft porcelain particles, then spreading the prepared soft porcelain particles in the mold, and then heating and drying to make it. The baking volume of the traditional baking box is not large, and each time only The amount of baking is not large, which seriously affects the production efficiency. Simply increasing the volume of the baking box can greatly improve the production efficiency, but the temperature field distribution in the baking box is difficult to arrange evenly. In order to ensure the same batch of baking process Consistent, the energy consumption per unit area will be greatly increased
