Processing equipment and processing method for improving wood breathability

Abstract

The invention discloses pre-processing equipment and a processing method for improving wood breathability. The device comprises a wood processing chamber in which a hollow cavity is arranged, an ultrasonic processing device, a wood holding assembly used for holding the wood to be processed, and a detecting device used for detecting the wood temperature, and the ultrasonic processing device is used for performing ultrasonic processing on the wood to be processed, wherein the wood to be processed is stacked on the wood holding assembly. The method disclosed by the invention is used for performing ultrasonic processing on the wood under a vacuum state so as to improve the wood breathability, get through the moisture passages in the wood to guarantee the smoothness of the passages when the moisture in the wood volatilizes during the drying process, improve the drying quality of the wood, reduce the drying defects during the drying process and shorten the drying period, and furthermore, the pre-processing equipment is simple, the operation is convenient, the processing technique conditions (pressure, ultrasonic power and frequency) are controllable, so that the equipment and the method are suitable for processing various types of wood.

Description

technical field [0001] The invention relates to a wood pretreatment device and a pretreatment method, in particular to a pretreatment device and a prediction method for improving the air permeability of hard-to-dry wood, and belongs to the technical field of wood pretreatment. Background technique [0002] Wood drying is the most important process in the production process of wood products. Under the action of heat, the moisture in the wood is discharged from the wood by evaporation or boiling vaporization, reducing the moisture content in the wood. The energy consumption of the wood drying process accounts for about 40% to 70% of the total energy consumption of wood product production. Correct and reasonable drying treatment of wood is not only the key to ensure the quality of wood products, but also an important means of rational utilization and saving of wood. However, for most woods with poor air permeability (such as catalpa, eucalyptus, catalpa, etc.), the traditional...

Problems solved by technology

Although this method has the following advantages and effects: (1) it is suitable for all wood as raw materials; (2) it has the advantages of simple method, strong operability, and safety and reliability; (3) it can better realize the improvement of the permeability of wood (4) Improve the permeability of wood by using the internal micro-explosion method of wood, and provide technical support for the functional modification of wood; (5) It is non-polluting and is a green and environmentally friendly production method; (6) Can manufacture Produce wood with good permeability, increase the specific surface area of ​​wood, and improve the environmental protection effect of wood, but this method is limited to processing wood with a thickness of 0.5-200mm, and a pressure vessel is used in the processing process, which is more dangerous. When the internal micro blasting treatment of wood, the moisture inside the wood moves slowly, the internal treatment is uneven, and drying defects are prone to appear, which affects the drying quality of the dried wood, and the drying cycle is long and the drying efficiency is low
