Roller kiln of double-layer microcrystalline foamed sheet

Abstract

The invention discloses a roller kiln of a double-layer microcrystalline foamed sheet. The roller kiln comprises a roller kiln body, wherein the roller kiln body is divided into a smoke exhaust area,a preheating area, a burning area, a rapid cooling area, a slow cooling area and a final cooling area in sequence in a transverse direction, the middle of the interior of the roller kiln body is divided into two upper and lower independent kiln spaces by a high-temperature backing plate and an interlayer square beam, and a first conveying roller way and a second conveying roller way are respectively installed in the roller kiln body up and down. According to the roller kiln of the double-layer microcrystalline foamed sheet, the structure mode that the middle of the kiln body is separated by the high-temperature backing plate is adopted to form the two upper and lower independent kiln spaces to produce products, compared with a single-layer roller kiln, the production yield of the double-layer roller kiln is increased by one time, the workshop occupied area is greatly reduced by the double-layer roller kiln equipment in the condition of the same yield, the number of employees of a double-layer roller kiln production line is the same as that of the single-layer roller kiln, and compared with two single-layer roller kilns, the number of workers of the double-layer roller kiln is reduced by half.

Description

technical field [0001] The invention relates to the technical field of roller kilns for microcrystalline foamed boards, in particular to a roller kiln for double-layer microcrystalline foamed boards. Background technique [0002] The existing production of microcrystalline foam boards is produced by single-layer roller kiln, the product output is very low, the energy consumption is high, and the production cost is relatively high. At the same time, when the factory expands production and needs to add new production equipment, it must At the same time, the production workshop will be expanded, and the production site will be increased, resulting in an increase in the construction of land and factory buildings. At the same time, under the condition of achieving the same production capacity, the double-layer roller kiln employs half the number of workers compared with the two single-layer roller kilns, which greatly alleviates the current problem of labor difficulties in domest...
