Four supporting plates are fixedly connected to the top face of the bottom plate, the same microwave heating box is fixedly connected to the top faces of the supporting plates, and a steam injection heater is installed at the position, close to the left side, of the top face of the bottom plate.

Description

technical field [0001] The invention relates to the field of medium density fiberboard processing, and more particularly, to an environment-friendly medium fiberboard fiber preheating combined process and its production equipment. Background technique [0002] Medium density fiberboard is a kind of artificial board made of wood fiber or other plant fiber as raw material, after crushing, fiber separation, drying, applying urea-formaldehyde resin or other suitable adhesive, and then hot pressing, because of its excellent performance, It is widely used in various fields. [0003] Among them, in the process of processing fiberboard, it is necessary to preheat the slab to ensure the quality of the finished board, while the preheating equipment in the prior art generally uses drying pipes or cyclones for drying. When pressing, the internal humidity is prone to errors, and when preheating, the slab can only be heated on one side. Since the slab cannot move, there are problems such...

Problems solved by technology

[0003] Among them, in the process of processing fiberboard, it is necessary to preheat the slab to ensure the quality of the finished board. However, the preheating equipment in the prior art generally uses drying pipes or cyclone separators for drying. When pressing, the internal humidity is prone to errors, and when preheating, the slab can only be heated on one side. Since the slab cannot be moved, there are problems such as uneven heating, and traditional heating equipment is not convenient for multi-layer heating of the slab. , the internal and surface properties of the slab are not optimal, and the service life of the slab is easily reduced
