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 single-plate drying unit.
Background technology
Recombinant Wood is that to take common wood (fast growing wood) be raw material, utilizes bionics principle, by common wood, fast growing wood being carried out to the more superior complete wooden new decorative material of a kind of performance of various modification materialization process for producing.With natural material, compare, hardly crooked, do not ftracture, non-warping.But its density manual control, product stability can be good, and in process, it does not exist natural timber to add waste and the Value Loss in man-hour, can bring up to the timber comprehensive utilization ratio 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 the finished product utilization rate is high, and finishing is more saved, and is to the excellent replacement of day by day rare wildwood resource, and the precious forest reserves are continued.In the manufacture process of Recombinant Wood, the Recombinant Wood veneer need to pass through the operations such as dyeing, oven dry, gluing, pressing, cutting just can be processed into flitch.At present, wood-working factory's dryer used is all generally to improve to make the wood single-plate that is positioned at baking oven to be dried the temperature in baking oven by radiator, so that follow-up processing and manufacturing.But directly by radiator, will in whole baking oven, be increased to uniform temperature, the required time is longer, and the heat loss of radiator is large, utilization rate is lower; And the drying effect of wood single-plate is poor.The patent No. is the patent that 201120161205.X, patent name are " lignum veneer drying-machine ", is respectively equipped with radiator in the both sides up and down of wood single-plate, can improve the drying efficiency of wood single-plate; But owing to having used two radiators, energy consumption is relatively high, because radiator is to integral heat sink in baking oven, can cause a large amount of heat-energy losses in addition, has further increased energy consumption; And this patent does not effectively reduce warm-up period.
