Abstract

The invention discloses a high-frequency vacuum drying tank for logs, which includes a tank body and an end cover, and a liquid collection tank is opened on the inner wall of the bottom along the axis of the tank body, and guide rails are respectively arranged at both ends of the liquid collection tank, and each guide rail There is a chute on the upper surface, and a plurality of suction holes are opened on the inner wall of the top along the axis of the tank body. The plurality of suction holes communicate with the suction pipes arranged on the outer wall of the tank body. A heating assembly is arranged on the outer wall; a card slot is opened on the upper surface of each longitudinal plate, and a plurality of sliding blocks are arranged in the middle of the lower surface of each transverse plate. The invention heats the log in a vacuum environment, and discharges the steam inside the tank in time to ensure that the wood inside the tank is heated evenly, the drying degree of the wood in different positions is consistent, and at the same time, the drying heat efficiency of the wood is guaranteed to be the same as that of drying The cost is positively correlated and the thermal efficiency of the drying tank is maximized while drying the wood.

Description

technical field [0001] The invention relates to the field of log processing, in particular to a high-frequency vacuum drying tank for logs. Background technique [0002] Timber needs to go through many processes from log to final product. Wood drying is to ensure the quality of wood and wood products and prolong the service life. Appropriate measures must be taken to reduce the moisture (moisture content) in the wood to a certain extent. . As a large energy consumer in the wood processing industry, wood drying accounts for 40-70% of wood processing energy consumption, and the thermal efficiency of drying is generally low, usually only between 30-40%; in addition, the pollution caused by the drying process is often It is an important source of environmental pollution in China. Taking the steam drying workshop with an annual drying capacity of 10,000 cubic meters as an example, the harmful substances discharged per hour are about 40Kg of smoke and dust, 1900 cubic meters of c...
