Embodiment

[0048] Material selection: southern masson pine, thickness 20mm

[0049] The high temperature and high pressure steam degreasing and deoiling process steps of pine wood include:

[0050] 1) Loading: Put the semi-finished wood products and wood trims on the track-type loading trolley 16;

[0051] 2), material into the tank: push the track-type charging trolley 16 into the wood degreasing and deoiling drying container tank 15, and close the tank door;

[0052] 3) Start work: Turn on the automatic control device 18 to make the whole set of devices enter the working state, turn on the bio-wood residue fuel boiler with steam superheating device 10 to transport the superheated steam to the wood degreasing and deoiling drying container tank 15;

[0053] 4), heat up and discharge the air in the container: open the sub-cylinder and the automatic steam distribution valve device 9 to heat up and steam the wood, open the emptying valve on the top of the wood degreasing and deoiling dryin...

Abstract

The invention relates to an integrated process for degreasing, deoiling and drying woods. The integrated process is characterized in that two processes including a high-temperature high-pressure steaming degreasing and deoiling process and a wood vacuum drying process are finished through one set of devices. The high-temperature high-pressure steaming degreasing and deoiling process comprises the following steps of: (1) performing truck loading; (2) putting materials in to a tank; (3) starting processing; (4) heating and discharging air in a container; (5) performing steaming; (6) utilizing heat energy; (7) liquefying grease; (8) collecting the grease; and (9) performing cyclic steaming. The vacuum drying process comprises the following steps of: (1) performing process conversion; (2) balancing the air humidity in the tank; (3) uniformly heating; (4) performing vacuum drying; (5) performing cyclic drying; and (6) slowly releasing internal stress of the woods. The integrated process is simple and reasonable and high in production efficiency, and can meet requirements for energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a wood processing method, in particular to an integrated process of wood degreasing, deoiling and drying. Background technique [0002] In recent years, with the continuous improvement of the economic level and the improvement of people's living standards, people's requirements for furniture range from simple practicability, wider design to technology, health, environmental protection and other requirements, and the base material of furniture is the most basic Factors, various manufactured products based on wood-based panels have been gradually replaced by natural wood products due to their shortcomings such as environmental protection, economy, and defects of non-natural products. [0003] Natural wood products are more and more favored by consumers. However, if the oil, moisture and impurities of natural wood are not removed, they will slowly leach out of the surface of the material during the use of the finished product, mak...
