Wood continuous rolling and impregnating device

Abstract

The invention discloses a wood continuous rolling and impregnating device. The device comprises an efficient and practical impregnating mechanism, a vacuum pump, a rail bracket, an U-shaped frame, a closing plate, a pressure sensor, a connecting pipe and rails; the rail bracket is welded with the efficient and practical impregnating mechanism, and the two form an integral molding structure; the bottoms of the rails are fixedly welded on the two sides of the top end of the rail bracket, and the two form an integral molding structure; and the back end of the vacuum pump is fixedly welded at thebottom of the front end of the efficient and practical impregnating mechanism, and the two are in reinforced connection through a screw. Rolled and impregnated woods are extruded and cleaned to removemodifier solution remained on the surfaces of the woods, so that the woods uniformly impregnated with modifiers and with clean surfaces are obtained, and the waste of the modifiers can be reduced; and then, a water extrusion roller performs water extrusion on the woods to realize impregnation of the woods with high water content, so that the requested impregnation quantity is reached, and meanwhile, the influence on the concentration of the modifiers and the impregnation effect by feeding of water in the woods into the modifier solution is prevented.

Description

technical field [0001] The invention relates to a continuous rolling impregnation device for wood, which belongs to the field of continuous rolling impregnation of wood. Background technique [0002] As a natural organic polymer material, wood has problems such as flammability, perishability, insect infestation, unstable size, and low physical and mechanical properties. For artificial fast-growing timber, the problems referred to above are particularly serious. These problems have greatly restricted the application of wood. In order to overcome the above-mentioned shortcomings of wood, people implement functional improvements to wood, such as using flame retardants to improve the fire resistance of wood, using preservatives to improve the corrosion resistance of wood, and using anti-mold agents to improve the mildew resistance of wood. Impregnating resin improves its mechanical properties and dimensional stability, etc. However, in the existing technology, for wood with h...

Problems solved by technology

[0003] In view of this, the embodiment of the present invention provides a wood continuous roll impregnation device to improve the existing technology. For wood with high moisture content, the amount of impregnation each time is lower, and the extruded moisture will enter In the modifier solution, dilute the modifier solution, affect the impregnation effect, and cause adverse effects
