Problems solved by technology

However, after the mica is calcined in the above scheme, the high-temperature mica heat is not collected, resulting in waste of heat energy; in addition, the above-mentioned calcining converter will generate a large amount of dust during operation, which not only pollutes the environment, but also endangers the health of the operators. And the purity of mica produced is low

Embodiment Construction

[0031] Such as Figure 1-5 Shown, a kind of mica calcining method comprises the following steps:

[0032] A, use the first mica conveying mechanism 102 to put the mica into the calciner 101 for calcination, and the calciner 101 is connected to the dedusting mechanism 5 for dedusting;

[0033] B, the mica in the calciner 101 is discharged in the second mica conveying mechanism 103, and the mica in the second mica conveying mechanism 103 is cooled with cooling jacket mechanism 1;

[0034] C. The cooled mica is sucked into the mica cooling tower 3 by negative pressure, sprayed and cooled, and rinsed to obtain pure mica.

[0035] Preferably, in step C, the mica after the cooling is sucked into the mica cooling tower 3 after passing through the sand and gravel settling mechanism 4; The settling box 41 connected, the bottom of the settling box 41 is provided with an openable and closed gravel discharge door 42, the side wall of the settling box 41 is located above the gravel disch...

Abstract

The invention provides mica and a calcining method thereof, belonging to the field of mica processing production technology. The calcining method comprises the following steps: A. conveying the mica into a calcining machine for calcining through a first mica conveying mechanism, and performing dust collection by connecting the calcining machine with a dust collection mechanism; B. discharging the mica in the calcining machine into a second mica conveying mechanism, and cooling the mica in the second mica conveying mechanism through a cooling jacket mechanism; and C. sucking the cooled mica into a mica cooling tower through negative pressure, so as to be spray-cooled, and rinsed to obtain clean mica. The calcining method has the advantages of being capable of recovering heat and improving a production environment, and the mica with higher purity can be obtained.

Description

technical field [0001] The invention belongs to the technical field of mica processing and production, and relates to a mica and a calcining method thereof. Background technique [0002] Usually, mica is calcined at high temperature to evaporate the crystallization water in the mica sandwich, so that the mica sheets expand between layers, so that the mica sheets are easy to peel off. In the process of calcining mica flakes with calcining equipment, mica flakes need to be heated to 920-950°C to evaporate the water of crystallization. [0003] The existing dust-free mica calcination production line is actually a calcination machine. The mica is fed from one end of the calcination machine and discharged from the other end. The crystal water in the mica is evaporated through high-temperature calcination. For example, the Chinese patent literature discloses an internal spiral mica calcining converter [Application No.: 200920199039.5], which includes a driven rotating drum, which...
