Veneer drying system

Abstract

The invention relates to the technical field of wood drying, in particular to a veneer drying system. A veneer drying system, the furnace body includes top, bottom and two front and rear side walls, the top of the furnace body is equipped with a circulation fan, the circulation fan includes an air inlet, a circulating air inlet and outlet, the air inlet is connected to an external air supply pipe, and the circulating air inlet and outlet Through the corresponding interface on the top of the furnace body to communicate with the interior of the furnace body, a circulating air duct is formed in the furnace body to dry the plates passing through it. The top of the furnace body is equipped with a non-powered exhaust air duct, and the side wall of the furnace body is a sandwich structure. After connecting the circulating air inlet and outlet, the air supply duct and the return air duct are formed. The inner wall of any one of the front and rear side walls of the furnace body is provided with a tuyere for air circulation, and any tuyere is a through-hole structure. , Unicom furnace body and air supply duct or Unicom furnace body and return air duct. Due to the adoption of the above technical scheme, the present invention saves energy and reduces emissions, and has high production efficiency, and the qualified rate of finished products is greatly improved compared with the natural drying method.

Description

technical field [0001] The invention relates to the technical field of wood drying, in particular to a veneer drying system. Background technique [0002] Among the wooden boards currently on the domestic market, multi-layer boards have the advantages of small deformation, high structural strength, and high environmental protection level, and the production of multi-layer boards has low requirements for raw materials, sufficient supply of raw materials, low production costs and cheap prices, so many The market share of laminates is quite large. [0003] At present, when domestic wood processing enterprises produce multi-layer boards, in order to save costs, the wood sheets planed from the logs generally adopt the natural dehydration method, that is, the sheets are dried in the sun, and the water is evaporated by sunlight. The moisture content of the sheet is reduced from about 40% to about 18%, which meets the moisture content requirement of the sheet when pressing the mult...

AI Technical Summary

Problems solved by technology

[0004] 1. Production activities are greatly affected by climate, and changes in climate conditions will seriously affect production tasks

[0005] 2. The labor intensity of the workers is high. During the drying process, the workers need to move and turn the wood to ensure that the moisture content is consistent.

[0006] 3. The production efficiency is low. Under normal circumstances, the drying time of wood is about 30 days.

[0007] 4. The production site is required to be large enough to dry in batches

[0008] 5. Areas with high air humidity are not suitable for production by drying

Due to the excessive heat energy in most factories, there is no need for more use of 300-degree hot air, which is discharged into the atmosphere through the flue, causing waste and a certain degree of heat pollution, which is contrary to the international development direction of energy conservation and environmental protection
