Solid multi-layer type single-plate dryer

Abstract

The invention provides a solid multi-layer type single-plate dryer, which comprises a baseframe, two lifting frame units, a hydraulic system, a heat conducting pipe coil assembly and positioning bolt mechanisms, wherein the baseframe is placed with the heat conducting coil pipe assembly; the two lifting units laterally stand at both ends of the baseframe; and the hydraulic system is arranged below a top lifting beam of the lifting units, provided with four two-way oil cylinders, and controlled by a hydraulic station to lift and fall back. Heat conducting coil pipe units are independent components, form the heat conducting coil pipe assembly by overlapping a plurality of layers, and are devices for inputting a heat source, radiating and drying. Both ends of the heat conducting coil pipe unit are fixedly connected with a set of the positioning bolt mechanisms respectively, and bolt rods of the positioning bolt mechanisms are closed or exculpated with positioning holes on the lifting frames so as to control the heat conducting coil pipe units to lift, and carry out material filling and discharging operation. The solid multi-layer type single-plate dryer has the advantages of three dimensions, small size, small occupation area, direct heating of wood plate surfaces, quick drying, high heat efficiency, energy conservation and low consumption. A single plate is not easy to warp and deform, so that the solid multi-layer type single-plate dryer also has the advantages of high finished product rate and simple operation, and is universal drying equipment.

Description

technical field [0001] The patent of the present invention relates to a three-dimensional multi-layer veneer dryer. Background technique [0002] The known drying of wood veneers is generally carried out by roller-type veneer dryers or mesh-belt veneer dryers at home and abroad, and even the latest veneer drying equipment such as continuous contact heating, which consumes a relatively large amount of steel. Large, large operating load, high operating cost, and these dryers are huge heavy equipment, occupy a large area, and have a large one-time investment. Many small and medium-sized enterprises who want to equip the plywood industry can only look forward to it. For this common problem in the plywood industry, the three-dimensional multi-layer veneer dryer is a popular drying equipment, and this equipment is also suitable for batch drying of other sheet materials. Contents of the invention [0003] The purpose of the patent of the present invention is to provide a three-d...
