Drying kiln for ceramic products

Abstract

The invention discloses a drying kiln for ceramic products. The drying kiln comprises a drying chamber, a drying preparation chamber, a conveying device and a control device; the conveying device penetrates through the drying chamber and the drying preparation chamber; a separating plate is arranged in the drying chamber; a first heating box is arranged above the separating plate; a first exhaustfan is arranged on the right side of the separating plate; a first placing rack is located below the separating plate; a second heating box is arranged below the first placing rack; an air blower is arranged on the left side of the first placing rack; a temperature sensor is arranged in the drying chamber; a communicating pipe is arranged at the upper end of the drying chamber; the other end of the communicating pipe communicates with the upper end of the drying preparation chamber; a second exhaust fan is arranged at the end opening of the communicating pipe; and a valve is arranged on the communicating pipe. Preliminary heat can be discharged into a drying preparation box by the aid of the communicating pipe after a drying procedure is completed, so that the drying time of the drying chamber is effectively shortened; the temperature of the drying chamber can be monitored by the aid of the temperature sensor, and the temperature of the drying chamber can be closest to the optimal drying temperature through adjustment and control by the aid of the control device.

Description

technical field

[0001] The invention belongs to the technical field of drying equipment, and in particular relates to a drying kiln for ceramic products. Background technique

[0002] Ceramic drying technology generally adopts hot air drying technology. There are three ways of energy sources: natural gas combustion, coal combustion and electric furnace. Sintering, heat preservation, cooling, and final molding, the traditional ceramic drying equipment has a long drying time and low efficiency, and the yield of finished products is not high, so most of them now use electric furnaces for drying. However, the current electric furnace kiln produces heat and cools down too fast, and it is easy to have dead angles in the drying process, so that the yield is not high, and the heat in the drying kiln body is difficult to circulate, which will cause color difference in ceramics; in addition , the temperature required for ceramic drying is about 1300 degrees, and the temperature of th...
