Abstract

The invention discloses a wood drying furnace, which comprises a furnace body, a flue communicated with a combustion chamber and a smoke outlet of the furnace body, the flue is fixed on the outside of the furnace body, and the flue and The furnace body is provided with a connected heat-conducting oil interlayer, and the heat-conducting oil interlayer is provided with an expansion oil pipe connected to the atmosphere, which is used for a hydraulic pump for circulating the heat-conducting oil in the heat-conducting oil interlayer; using heat-conducting oil as a medium, it can Obtain a higher drying temperature, and the temperature is easy to control, which greatly saves the drying time. Since the heat transfer oil interlayer is equipped with an open water collection tank, the amount of water can be increased or decreased according to the need, so that the humidity of the hot air can be controlled. The dried wood will not be cracked, deformed, discolored, and dried evenly, which improves the quality of the product. When the heat passes through the flue, it can be fully absorbed by the heat conduction oil in the flue interlayer, so that the heat can be fully utilized and improved. Heating speed, high thermal efficiency, saving fuel.

Description

technical field

[0001] The invention relates to the technical field of drying equipment, in particular to a wood drying furnace. Background technique

[0002] At present, there are mainly two types of equipment for drying wood in the drying kiln, one is a hot blast stove and the other is a steam boiler.

[0003] The hot air stove first heats the air into hot air, and then circulates the hot air in the drying kiln through the air induction or blowing equipment, so as to achieve the effect of drying wood. However, when the hot air stove is used for wood drying, there are The following disadvantages: 1) If the heating of the hot blast stove is stopped, the temperature in the drying kiln will drop rapidly, and cracks will appear in the wood due to the large temperature difference in a short period of time, which will affect the drying quality; 2) The heat exchange medium of the hot blast stove is air, The thermal conductivity of the air is small, and the temperature of the hot ...
