Abstract
The invention discloses a wood veneer dryer comprising a drying oven. A feed inlet and a discharge outlet are formed at two ends of the drying oven respectively, the drying oven is internally divided into an upper dying bin and a lower heat storage bin through an insulation board, two layers of feed rollers are arrayed in the upper drying bin, and wood veneers pass through from positions between the two layers of feed rollers. An hot air pipe is arranged between every two adjacent feed rollers in the same layer, all the hot air pipes are communicated with a fan A, and a radiator is arranged in the lower heat storage bin which is communicated with the upper drying bin through a fan B. The fan A and the fan B are arranged in the upper dying bin or the lower heat storage bin. According to the structure, the wood veneer dryer can dry the wood veneers and is high in drying efficiency, drying time for single wood veneers is shortened, and drying efficiency is improved. Since the radiator is arranged in the lower heat storage bin independently, the wood veneer dryer has the advantages of quickness in warming and low heat loss, energy consumption needed for drying is reduced, and production cost of enterprises is lowered.
Description
Technical field
The present invention relates to wood processing field, be specifically related to a kind of wood veneer dryer.
Background technology
Recombinant Wood be with common wood (fast growing wood) for raw material, utilize bionics principle, by the entirely wooden new decorative material that a kind of performance of common wood, fast growing wood being carried out to various modification materialization process for producing is more superior.Compared with natural material, bend hardly, do not ftracture, non-warping.Its density can manual control, and product stability can be good, and in process, it does not exist waste and the Value Loss that natural timber adds man-hour, wood comprehensive utilization rate can be brought up to more than 85%.And compare with natural wood, Recombinant Wood has following characteristics: rich color, and texture is various, and properties of product are more superior, and finished product utilization rate is high, and finishing is more saved, and is the excellent replacement to day by day rare wildwood resource, and the precious forest reserves are continued.In the manufacture process of Recombinant Wood, Recombinant Wood veneer needs just can be processed into flitch through operations such as dyeing, oven dry, gluing, pressing, cuttings.At present, the dryer that wood-working factory is used is all generally the wood single-plate being positioned at baking oven is dried, so that follow-up processing and manufacturing the temperature raising in baking oven by radiator.But be directly increased to uniform temperature by radiator by whole baking oven, the required time is longer, and the heat loss of radiator is comparatively large, utilization rate is lower; And the drying effect of wood single-plate is poor.The patent that the patent No. is 201120161205.X, patent name is " lignum veneer drying-machine ", is respectively equipped with radiator in the both sides up and down of wood single-plate, can improves the drying efficiency of wood single-plate; But owing to employing two radiators, energy consumption is relatively high, in addition because radiator is to integral heat sink in baking oven, a large amount of heat-energy losses can be caused, further increase energy consumption; And warm-up period does not effectively reduce by this patent.
