Plate drying machine with preheating function

Abstract

The invention discloses a plate drying machine with the preheating function. The plate drying machine comprises a drying cabinet; the right side surface of the drying cabinet is provided with an exhaust pipe which communicates with an inner cavity of the drying cabinet; cabinet doors are arranged on two sides of the front surface and the back surface of the drying cabinet through hinges respectively; a partition plate which is vertically arranged and is welded to the inner wall of the drying cabinet is arranged in the middle of the inner cavity of the drying cabinet and divides the inner cavity of the drying cabinet into a drying cavity body and a preheating cavity body; and a first through groove communicating with the drying cavity body and the preheating cavity body is formed in the drying cabinet. The plate drying machine with the preheating function has the advantages that waste heat of hot air in the drying cavity body is discharged into the preheating cavity body for preheating plates, and therefore the waste heat can be fully utilized; due to the preheating effect of the exhaust pipe, the drying efficiency is high when the plates in the exhaust pipe are placed into the drying cavity body; and the shunting effect of second through grooves and the first through groove is utilized so that the bottom surfaces and the upper surfaces of the plates placed on rotating shafts can be heated, and therefore the drying efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a plate dryer with a preheating function. Background technique [0002] Wood is the lignified tissue of plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome becomes active, developing bast outward and wood inward. Wood is the general term for plant tissues that develop inwardly from the vascular cambium, including xylem and parenchyma rays. Wood plays a great supporting role in human life. According to the different properties and characteristics of wood, people use them in different ways. The board is processed from wood, such as plywood and so on. These boards need to be dried after processing to prevent the boards from going mildew or being corroded by insects and fungi during storage, transportation and use, as well as splitting and deformation of the boards. The current b...
