A drying structure for reducing the moisture content of log planks

Abstract

The invention discloses a drying structure for reducing log board water content. The drying structure comprises a tank body and an end cover; a liquid collecting tank is formed in the inner wall of the bottom of the tank body along the axis of the tank body; guide rails are arranged at the two ends of the liquid collecting tank; chutes are formed in the upper surfaces of the two guide rails; multiple suction holes are formed in the inner wall of the top of the tank body along the axis of the tank body, and communicate with suction pipes arranged on the outer wall of the tank body; clamping grooves are formed in the upper surfaces of all longitudinal plates; and multiple slide blocks are arranged at the middle parts of the lower surfaces of all transverse plates. The drying structure heatslogs under vacuum environment, and timely exhausts steam in the tank body to guarantee uniform heating of the logs in the tank body, so that the drying degrees of the logs in different placing positions are the same, meanwhile, the drying efficiency and the drying cost of the logs are in positive correlation, and the maximum heat efficiency of the drying tank in log drying is achieved.

Description

technical field [0001] The invention relates to the field of log processing, in particular to a drying structure for reducing the moisture content of log boards. 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, ...

AI Technical Summary

Problems solved by technology

The reason is that when drying wood, ordinary drying tanks cannot effectively use its limited space, and the drying efficiency is low, and secondary drying treatment is required, which increases the processing energy consumption again.
