Equipment with automatic novel cooling mode for low-temperature glaze firing product

Abstract

The invention discloses equipment with an automatic novel cooling mode for a low-temperature glaze firing product. The equipment with the automatic novel cooling mode for the low-temperature glaze firing product comprises a shuttle-type electric cubic kiln, a kiln car and a heat extraction windmill, wherein a cooling air chamber is arranged in the side wall of the shuttle-type electric cubic kiln;a cooling air inlet is formed in the bottom part of the cooling air chamber; a wall air inlet pipe is arranged on the inner side wall of the cooling air chamber; an air outlet and a hot air channel are arranged on the bottom part of the kiln car; a hot air channel of the shuttle-type electric cubic kiln communicates with the hot air channel of the kiln car; and a hot air pipeline of a windmill isarranged between the shuttle-type electric cubic kiln and the heat extraction windmill so as to be used for connecting the shuttle-type electric cubic kiln and the heat extraction windmill. After theshuttle-type electric cubic kiln is cooled to reach the preset temperature below 1200 DEG C, a cooling system is started, and cooling air enters the kiln through an optimized channel through a reasonable design of an inner structure of a kiln furnace, so that automatic cooling is realized without the need for opening a kiln door. The cooling time is 220 minutes in the whole process, and the speedis faster than before, so that the aim of quickly cooling is achieved, slags cannot fall, and the glaze brightness is bright and uniform.

Description

technical field [0001] The invention relates to the field of low-temperature glaze firing, in particular to a device for automatic cooling of low-temperature glaze firing products. Background technique [0002] Traditional kilns are cooled by slowly opening the kiln door and cooling down slowly. It takes more than 90 minutes for the traditional kiln to drop from 1200 degrees to 900 degrees, and more than 270 minutes for 900 degrees to 200 degrees. A large amount of cold air is in direct contact with the glaze surface, and when it enters the kiln, it will bring out slag points during the gyration process. The temperature will drop for more than 360 minutes in the whole process, and the slag will fall, and the brightness of the glaze surface will be poor and uneven. [0003] There is a need for a device that does not need to open the kiln door, has its own cooling system, changes the internal structure of the kiln and the design of the cooling method, and uses gate control to...
