Embodiment 1

[0037] An environmentally friendly and efficient veneer drying device, comprising a board inlet 101, a board outlet 102, a rack 10, a thermal insulation box 11, a top cover 12, a moisture outlet 13, a conveying mechanism 14, a blowing device 19, and a fire channel 20 , flue gas duct 22, flue 23; the frame 10 is mainly composed of channel steel, square steel, angle steel, I-beam, steel plate, and the frame 10 is used to carry the conveying mechanism 14, the blowing device 19, the fire channel 20, The flue gas duct 22 and the flue 23; the outer side of the frame 10 is provided with a thermal insulation box 11, the upper part of the thermal insulation box 11 is provided with a top cover 12, and a number of moisture outlets 13 are provided on the top cover 12 near the outlet 102 ;

[0038] The transmission mechanism 14 includes a transmission shaft 400, a clamping arm 401, a support pad 402, a chain 403, a sprocket 404, a roller 405, a motor 406, a reducer 407, and a motor fixing ...

Embodiment 2

[0041] The difference from Embodiment 1 is that a chain bracket 409 is provided at the bottom of the upper transmission chain 403 in the transmission group to prevent the chain 403 from bearing the veneer 9 from falling due to gravity, and the transmission resistance of the chain 403 is large, which affects the stable operation of the transmission mechanism 14; A chain hanger 410 is provided on one side of the transmission chain 403 in the middle and lower part of the transmission group to prevent the chain 403 from falling due to its own gravity during the transmission process, which affects the stable operation of the transmission mechanism 14 .

[0042] The ventilation pipe 4011 in the clamping arm 401 is a square pipe or a round pipe, the veneer is clamped by the ventilation pipe 4011, and the hot air can flow in the opposite direction through the ventilation pipe 4011 in the clamping arm 401, so that the veneer 9 effective drying.

Embodiment 3

[0044] The difference from Embodiment 1 is that a plurality of support bars 4014 are provided on the ventilation pipe 4011 in the clamping arm 401, so that the clamping arm 401 can dry multiple veneers on the same horizontal plane, and the supporting bars 4014 assist The clamping arm lifts a plurality of veneers to increase the number of veneers to be dried, thereby improving the efficiency of veneer drying.

Abstract

The invention provides an environment-friendly and high-efficiency veneer drying device, which includes a board inlet, a board outlet, a rack, a thermal insulation box, a top cover, a moisture outlet, a conveying mechanism, a blowing device, a fire duct, a flue gas duct, a flue; a thermal insulation box is arranged on the outside of the frame, a top cover is arranged on the upper part of the thermal insulation box, and a number of moisture outlets are arranged on the top cover near the outlet of the plate; the transmission mechanism includes a transmission shaft, a clamping arm, Support pads, chains, sprockets, idlers, motors, speed reducers, and motor fixing frames, the upper part of the chain is provided with a supporting pad, the upper part of the supporting pad is provided with a clamping arm, the fire channel, smoke The pipes and the flue are fixedly connected to the frame; the blowing device is arranged on both sides of the upper circulation part of the conveying mechanism and both sides of the fire channel, and the blowing device includes a baffle, a blowing fan and a fan support. The invention has low energy consumption, reduces the production cost of traditional large-scale drying equipment, has good veneer drying effect, and solves the problem of natural warpage of the veneer after drying.

Description

technical field [0001] The invention belongs to the technical field of wood drying equipment, in particular to an environment-friendly and efficient veneer drying device. Background technique [0002] Timber veneer, also known as veneer, veneer, its thickness is usually between 0.4-10mm, the main purpose is to produce plywood, blockboard, template, veneer and other artificial boards; veneer is divided into two kinds of rotary cutting and slicing , veneer drying or drying is a product that consumes a lot of labor. [0003] The traditional drying method is to dry the peeled or planed wood veneer one by one in the sun, and dry the wood veneer 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 weather conditions. [0004] At present, the drying equipment of many ve...
