Description

Technical Field

[0001] The utility model relates to the technical field of calcium silicate board production equipment, in particular to a drying device for calcium silicate boards. Background Art

[0002] Calcium silicate board is a board made of loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials, and silicon and calcium materials as the main bonding materials. It is made of calcium silicate gel through pulping, molding, and accelerating the curing reaction in high temperature and high pressure saturated air. During the processing of calcium silicate board, the molded calcium silicate board needs to be dried to facilitate the subsequent demoulding of the calcium silicate board.

[0003] In actual use, the existing calcium silicate board drying device needs to turn over the calcium silicate board during the drying process to improve the drying uniformity and drying efficiency of the calcium silicate board. The Chinese utility model patent "A dryer for producing calcium silicate boards" with patent number 202321309195.9 discloses a method of using a sealed door to close the box to avoid heat loss to improve the drying efficiency of the calcium silicate board, as well as a technical solution of using a movable clamp to adapt to the fixation of calcium silicate boards of different sizes. Although it can achieve the technical effect of improving the drying efficiency to a certain extent, there is still a defect that it is inevitable that the bottom of the calcium silicate board cannot be dried during use, resulting in uneven drying and affecting the drying quality.
