Dryer for uniformly drying solid wood board raw materials

Abstract

The invention discloses a dryer for uniformly drying solid wood board raw materials. The dryer comprises a bracket and a conveying belt matched with the bracket, wherein a plurality of drying cavities which are arranged side by side and are communicated with one another are fixedly formed on the upper part of the conveying belt; inlet ends and outlet ends are formed at two sides of the drying cavities; upper and lower rows of magnetrons which are parallel with one another are fixedly arranged on the inner walls of the drying cavities; small rollers and big rollers are fixedly arranged at the inlet ends and the outlet ends of the drying cavities by virtue of connecting rods A and connecting rods B, and the bottom ends of the small rollers and the big rollers are located on a same linear line; after logs enter the drying cavities, the upper surfaces of the logs are directly contacted with the outer circumferences of the small rollers, and after the logs move by a distance, the upper surfaces of the logs are contacted with the outer circumferences of the big rollers; under the squeezing of the big and small rollers, the logs are dried and dewatered, and meanwhile the logs are prevented from becoming twisted or deforming integrally; and the moving track of the logs is not affected even if the conveying belt shakes or jumps with a certain degree during conveying, so that the uniform drying of the logs is guaranteed.

Description

technical field [0001] The invention relates to a dryer, in particular to a dryer used for uniform drying of solid wood board raw materials. Background technique [0002] Solid wood boards are durable and have natural textures. Most of them have the unique aroma of natural wood. They have good hygroscopicity and air permeability. However, due to its complex processing technology and high level of operation requirements, the drying of logs is not satisfactory, which can easily cause problems such as poor product quality stability, cracking, deformation, and weak paint adhesion. Traditional wood drying methods generally use steam. , heat transfer oil, charcoal, etc. to dry the wood, it usually takes several months to complete the drying, the drying time is long, time-consuming and laborious, a lot of energy is wasted, the environment is polluted, the drying effect is not good, and the moisture distribution in the wood will be uneven , affecting product quality and causing was...
