A method for sizing granular materials and a sizing device

Abstract

A glue sizing method and device for granular materials, the materials are bundled downward at an initial speed, clustered into a column and continuously unloaded towards the cone top of the cone, the materials slide down along the cone surface, and the materials in the process of falling are covered by diameter The gradually increasing cone surface thins and covers the cone surface dynamically in the form of a film until the material slides to the bottom of the cone and continues to fall in the shape of a circular curtain waterfall along the outer edge of the cone bottom. The curtain waterfall-shaped material falls through a negative pressure area and is subjected to Negative pressure suction, the material particles move laterally to the lower space inside the outer edge of the cone bottom, where they are mixed with the glue that is sucked down there by negative pressure and output. , and at the same time realize the sizing of material particles; the output port of the glue solution is located above the space. In the method and device, the mixing, sizing and material process of the material and the glue are carried out simultaneously, which is not only beneficial to continuous production, but also the material and the glue are fully mixed, the sizing is sufficient, and the material particles will not block the glue during the sizing process. liquid outlet.

Description

technical field [0001] The invention relates to the field of surface sizing and spraying of granules, in particular to a sizing method and device for wood-based panel material granules. Background technique [0002] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various small particle unit materials by certain mechanical processing, and glued with or without adhesives and other additives. [0003] In order to make the unit materials of small particles (such as shavings and straw) glue well, the limited adhesive must be evenly distributed to the surface of the material particles. This process is called sizing. [0004] A foreign spray sizing process uses multiple parallel clamping conveyor rollers arranged up and down to spread the material repeatedly on the conveyor belt, and then unloads the material in a straight curtain waterfall from the output end of the conveyor belt, and then discharges it from the curtai...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a sizing method for granular materials and a sizing device for granular materials. The method and device have a simple diluting structure and good diluting effect. The material process is carried out at the same time, which is not only conducive to continuous production, but also the material and glue are fully mixed, the glue is fully applied, and the material particles will not block the glue outlet during the glue application process.
