A horizontal frying board kiln for mica ore microwave calcination

Abstract

The invention discloses a mica mine microwave calcination horizontal parching plate kiln. A microwave heating drying zone furnace body (5), a microwave heating warming zone furnace body (6) and a microwave heating holding zone furnace body (7) are installed on a machine frame (12) according to the principle of high feed ends and lower discharge ends; a furnace tube (16) is installed in each furnace body; microwave generators (18) are installed on the left and right sides of each furnace body; a feed section (4) is installed on the front end of the microwave heating drying zone furnace body (5), and a slow cooling section (9) and a discharge section (10) are installed on the back end of the microwave heating holding zone furnace body (7); a stirring shaft (8) penetrates through the feed section (4), microwave heating drying zone furnace body (5), microwave heating warming zone furnace body (6), microwave heating holding zone furnace body (7), slow cooling section (9) and discharge section (10); the machine frame (12) is provided with a transmission system (1) which is connected with the stirring shaft (8) in a transmission mode; and the stirring shaft (8) is provided with a parching plate. On the basis of the characteristics of the microwave heating, the kiln has the advantages of high heating speed, high production efficiency, high product quality and no environmental pollution, and is more energy-saving than the conventional kiln.

Description

technical field [0001] The invention relates to a frying board kiln, in particular to a horizontal frying board kiln for microwave calcination of mica ore. Background technique [0002] Mica calcination is to heat mica to a certain temperature and keep it warm for a period of time to remove the crystal water in the mica crystals, so that the mica will undergo significant expansion and stratification along the vertical direction of the cleavage plane during the dehydration process, becoming Loose and soft. The traditional mica calcination method is to use an electric kiln to heat the mica. The mica is heated unevenly, and the heating time is long, which is not conducive to the stratification of the mica, and the energy consumption is high. [0003] Microwave energy is known as "the second flame of mankind", and microwave energy application technology has been defined as "new generation technology in the 21st century", "advanced preparation technology of new materials" and "f...
