The invention discloses a multi-layer and multi-stage
pipe tunnel slide type
veneer drying device. The multi-layer and multi-stage
pipe tunnel slide type
veneer drying device comprises a
drying box, a conduction oil boiler, a conduction oil circulating pipeline and a
circulating pump, wherein the conduction oil circulating pipeline is connected with the drying box and the conduction oil boiler, and the
circulating pump is arranged on the conduction oil circulating pipeline. A drying frame is arranged in the drying box, and a heat
insulation layer is arranged on the periphery of the drying box. Being different from the prior art, the drying frame is formed by heating plates and bearing and supporting partition plates, wherein the heating plates are arranged in parallel in the quasi-horizontal direction,
heating oil pipelines are buried in the heating plates, and the bearing and supporting partition plates are arranged in parallel in the vertical direction; a plurality of
layers and a plurality of columns of flat rectangular
pipe-tunnel-shaped spaces of the same specification are formed in the drying frame at equal intervals and in parallel and serve as pipe tunnel type drying chambers, and material enters or exits from the drying chambers in a sliding mode. The multi-layer and multi-stage pipe tunnel slide type
veneer drying device has the advantages that the manpower and the
electric energy are saved, the
heat energy is reasonably recycled, the heat dissipation rate is low, it is difficult to catch fire but easy to extinguish fire, the structure is simple, the manufacturing cost is low, the investment is small, and use and popularization are convenient.
