Description

Fiberboard drying equipment

Technical Field

The utility model relates to a fibreboard drying technique field specifically is a fibreboard drying equipment.

Background

The artificial board is made of lignocellulose fiber through interweaving and shaping and utilizing the inherent adhesive property. During the manufacturing process, adhesives and/or additives may be applied, and the basic units constituting the fiberboard are separate wood fibers or fiber bundles. The raw materials for preparing the fiber mainly come from forest logging residues, such as branches, tips, small logs and the like; and wood processing residues such as board edges, shavings, sawdust, and the like. In addition, the waste of forest chemical processing (such as tannin extract and hydrolyzed residue) and other plant stems can be used for preparing fiber. The needle wood has high fiber content, and the fiber length is 30-50% longer than that of the broad-leaf wood. If broad-leaved wood is used, the treatment is carried out firstly: the method can be used for pulping by mixing needle and broad wood, or treating wood chips by chemical method, or using hot water and steam. Before the fiber separation, the raw material is sliced into thin slices with the length of 20-30 mm, the thickness of 3-5 mm and the width of 15-25 mm by a slicing machine. The wood chips are too large, and are difficult to soften or not softened uniformly in the preheating treatment and pulping processes, and the fiber separation degree is low; too short wood chips result in a large proportion of cut fibers and poor interlacing properties, resulting in a decrease in the strength of the fiberboard. The cut wood chips are sent into a storage bin after the processes of screening, crushing, washing and the like for fiber separation.

However, the fibers required by the existing fiberboard are processed by virgin wood, and the wood contains certain moisture which is shrunk in the wood fibers, so that the traditional air drying efficiency is long in time consumption and low in working efficiency; thus, the existing need is not met, for which we propose a fiberboard drying apparatus.
