Mica-paper drying system

Abstract

The invention discloses a mica-paper drying system. The mica-paper drying system comprises mica paper, a drying cylinder and a supporting frame. A pre-drying cover is arranged over the drying cylinder; the pre-drying cover is fixedly connected with the supporting frame; a first support and a second support are arranged on the left side and the right side of the supporting frame respectively; a first rolling wheel and a second rolling wheel are arranged on the first support and the second support respectively; a first transition plate and a second transition plate are connected to the lower left end and the lower right end of the pre-drying cover respectively; a pressing wheel is arranged above the first rolling wheel; a heat-dissipation fiber-taking-off device is arranged at the lower right portion of the drying cylinder; a plurality of evenly-arranged heating pipes are arranged in the pre-drying cover and fixed on an arc supporting rod; the mica paper is conveyed through the first rolling wheel, the pressing wheel, the upper surface of the pre-drying cover, the second rolling wheel, the drying cylinder and the heat-dissipation fiber-taking-off device in sequence. By means of the mica-paper drying system, the drying time can be shortened, rapid cooling is achieved, the production efficiency of the mica paper is improved, and the technical problems that the mica paper is crinkled, fractured, subjected to fiber exposure and the like in the drying process are solved.

Description

technical field [0001] The invention belongs to the technical field of mica processing, in particular to a mica paper drying system. Background technique [0002] Mica paper is made of mica minerals. It is made into rolls by chemical pulping or hydromechanical pulping at a slow speed of the cylinder paper machine, and then cut into roll paper or flat paper. Mica paper has excellent properties such as heat resistance, water resistance, chemical stability, high elasticity, high peelability, high shear resistance and tensile strength, and is currently widely used in the field of electrical insulation for de-wired motors. [0003] The production process of mica paper mainly includes seven steps, namely crushing, grading, pulping, papermaking, molding, pressing and drying, among which drying plays a crucial role as the last step. If the drying time is not long enough, the mica paper produced will have high humidity and low tensile strength, resulting in a low utilization rate wh...

Problems solved by technology

[0005] During the production and processing of mica paper, some animals, plants or chemical fibers are often added according to needs to improve the flexibility and strength of mica paper, and fiber mica paper is obtained; during the drying process of fiber mica paper, as the temperature increases, Elevation, evaporation of water, and transfer of rollers tend to produce fiber filaments, which makes the surface of the processed mica paper rough and lacks luster, which affects the quality of the mica paper
