Multi-layer and multi-stage pipe tunnel slide type veneer drying device

Abstract

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.

Description

technical field [0001] The invention relates to the field of heat energy application, in particular to a multi-layer and multi-stage pipe hole slide type veneer drying device which uses heat conduction oil for heat supply. technical background [0002] There is a process in wood processing: cutting the felled logs into certain specifications of raw wet wood chips, that is, veneers, and these veneers need to be dried for transportation, storage or further processing. Drying methods generally include sun drying and equipment drying. Existing drying equipment for drying veneers can be roughly divided into two categories: one is to transfer heat to the veneer through air flow, and the veneer obtains heat energy and evaporates water to dry. The other is to use heat conduction to transfer heat energy to the veneer through the contact between solids, and the veneer obtains heat energy, the temperature rises, and the water evaporates and dries. The former, such as drying room and ...

AI Technical Summary

Problems solved by technology

The former, such as drying room, tunnel drying line, etc., belong to this category. The disadvantages are large space occupation, high heat dissipation, slow speed and low efficiency.

The latter, such as multi-layer hot-press dryers, roller-type veneer dryers, etc., belong to this category. The advantage is that the drying speed of the monomer is fast, and the disadvantage is that the energy consumption is high, and the equipment manufacturing cost and use cost are high.

No matter whether the former or the latter is used, it will consume a lot of labor, and it is impossible to save energy and labor, and it is impossible to reduce the cost of equipment manufacturing.
