A high-efficiency energy-saving veneer drying device

Abstract

The invention provides a high-efficiency and energy-saving single-plate dryer which mainly comprises a heat-preservation box body, a drying device, a transmission device and a power device. The high-efficiency and energy-saving single-plate dryer is characterized in that the heat-preservation box body is composed of a plurality of fireproof heat-preservation plates; the drying device comprises lateral drying ovens and a central drying oven, the lateral drying ovens are located on the two sides of the heat-preservation box body, small holes are formed in the upper portions of the lateral drying ovens, and large holes are formed in the lower portions of the lateral drying ovens; the central drying oven is located in the middle of the heat-preservation box body, and vent holes are formed in the upper portion of the central drying oven; the transmission device mainly comprises gears, transmission shafts, bearings, chains, steel bars and supporting plates, the gears at the two ends of the central drying oven form an upper-layer transmission loop, the central drying oven is located in the middle of the upper-layer transmission loop, and the chains move on the corresponding gears cyclically; the power device comprises a motor, a speed reducer I, a belt wheel and a belt, and the motor provides power by converting belt transmission into chain transmission. The high-efficiency and energy-saving single-plate dryer is simple in structure, low in production cost, low in energy consumption and good in drying effect.

Description

technical field [0001] The invention belongs to the technical field of wood drying equipment, in particular to a high-efficiency and energy-saving veneer drying device. Background technique [0002] Wood veneer, also known as veneer, veneer, its thickness is usually between 0.4-10mm, the main purpose is to produce artificial wood boards such as plywood, blockboard, formwork, veneer; veneer is divided into two types: rotary cutting and planing , veneer drying or drying is a product that consumes a lot of labor. [0003] The traditional drying method is to dry the wood veneers that are rotary cut or sliced ​​one by one in the sun, and dry the wood veneers through water evaporation, but the disadvantage of this drying method is that it takes up a lot of space , the production efficiency is low, and the wood veneer after drying is easy to roll and deform, the quality is difficult to guarantee, and it is also restricted by the weather conditions. [0004] At present, the drying...

[0003] The traditional drying method is to dry the wood veneers that are rotary cut or sliced ​​one by one in the sun, and dry the wood veneers through water evaporation, but the disadvantage of this drying method is that it takes up a lot of space , the production efficiency is low, the wood veneer after drying is easy to roll and deform, the quality is difficult to guarantee, and it is also restricted by the weather conditions

[0004] At present, the drying equipment of many veneer manufacturers is earth kiln drying, that is, baking with fire. In this way, the dough can also be dried, but the water content is very uneven; in view of this, large-scale factories now use Advanced drying equipment is used to dry with heat-conducting oil. With such a production line, the veneers baked out not only have good flatness, but also have relatively uniform moisture content, but the initial investment is large, energy consumption is large, and production costs are high.

[0005] Chinese Invention Patent (Patent No.: 201120161205.X) discloses a wood veneer dryer, which mainly uses a plurality of roller groups arranged horizontally in the oven, and each roller group includes a corresponding upper roller and a The lower roller, the lower roller is the active roller driven by the power device, and the upper and lower parts of the multiple roller groups are respectively equipped with heat dissipation devices, and the roller groups clamp the wood veneer during the forward process, and the wood that is peeled out The veneer becomes smooth and dry due to being clamped and squeezed by the upper roller and the lower roller, but the wood veneer dryer has a small amount of dried veneer due to the design of multiple roller groups. , takes up a large area, the number of veneer skins to be dried per unit time is small, the production efficiency is relatively low, and the production cost is high
