Abstract

The invention provides a log high-pressure vacuum treatment device and a log high-pressure vacuum treatment method. The device comprises a gas suction disc device, a first stainless steel pipe, a second stainless steel pipe, a first rubber pipe, a second rubber pipe, a first valve, a second valve, a temperature sensor, a first barometer, a second barometer, a data measurement recorder, a vacuum pump, a vacuum buffering tank, and a steam generator. The gas suction disc device is composed of a first conical stainless steel tank, a second conical stainless steel tank, a first larger small head rubber sleeve, a smaller small head rubber sleeve, and a hoop device. The invention also provides a log high-pressure vacuum treatment method which is a method for carrying out high-pressure vacuum treatment upon log by using the log high-pressure vacuum treatment device. According to the device, the conical suction disc device can be adapted to wood diameter grade change. Devices on two ends of a log are not integral, such that the device can be adapted to requirements of logs with different lengths. With the device, logs with different sizes can be treated, such that a problem of the limitation of processible log size is solved.

Description

technical field [0001] The invention relates to a log high-pressure vacuum treatment equipment and method, belonging to the technical field of wood treatment. Background technique [0002] Logs are raw materials for the production of the timber industry. Cut down the growing trees in the forest, remove the branches and form the trunk part of the original bar, and then cut it into a certain type of wood according to the length direction of the original bar, according to the size, shape, quality and national timber standards or plans made by the enterprise The wood segments become logs. When the wood is just felled, the ratio of its water weight to its absolute dry weight, that is, the wood moisture content (absolute moisture content) commonly used in the wood industry, generally reaches 70-140%, and the sapwood is generally higher than the average of the whole wood in its parts. The moisture content is also high. However, the moisture content of wood soaked in water for a ...
