Wood chip drying device

Abstract

The invention discloses a wood chip drying device which comprises a boiler (1), a tail gas pipe (1a) is arranged on the boiler (1), and a water dust scrubber (2) is arranged on the tail end of tail gas pipe (1a). The wood chip drying device further comprises a dirt catcher (3) which is communicated with the tail gas pipe (1a). The wood chip drying device further comprises an air heating chamber (5) which is provided with an air heat exchanger (6) communicated with the dirt catcher (3) inside. A draught fan (9) is arranged outside the air heating chamber (5), and an air outlet pipe (9a) extends into the air heating chamber (5). The wood chip drying device further comprises a drying channel (10), wherein the drying channel (10) is communicated with the air heating chamber (5), and a through pipe line (11) above the drying channel (10) is communicated with the air heating chamber (5). The air heat exchanger (6) is also communicated with the steam outlet of the boiler (1), an electrically operated valve (16a) is arranged on a communicating pipe (16), and the electrically operated valve (16a) is in communication with a temperature sensor (15). The wood chip drying device is energy-saving and environment-friendly, and reduces producing cost greatly, and meanwhile drying effect is good.

Description

technical field [0001] The invention belongs to the field of wood processing devices, in particular to a device for drying veneer chips. Background technique [0002] Wooden boards are usually formed by compacting multiple layers of veneer through a press. There are strict control requirements for the moisture content of the veneer used, and during the production process, the veneer needs to be dried and dehydrated. The traditional way is natural drying and dehydration, although this dehydration method is more economical and convenient. However, it is not easy to grasp the degree of drying, which often leads to excessive dehydration of the wood chips, resulting in brittleness and bending of the wood chips, which seriously affects the quality of the final product; at the same time, natural drying is subject to weather factors; if it is raining, the wood chips cannot be treated. Drying and dehydration will affect the overall production progress. Although most enterprises ha...

However, it is not easy to grasp the degree of drying, which often leads to excessive dehydration of the wood chips, resulting in brittleness and bending of the wood chips, which seriously affects the quality of the final product; at the same time, natural drying is subject to weather factors; if it is raining, the wood chips cannot be treated. Drying and dehydration will affect the overall production progress

Although most enterprises have widely used boiler equipment to dry wood chips, most of the existing equipment consumes a lot of energy, and it is difficult to control the degree of drying
