A Material Sorting Mechanism Used in Man-made Panel Production

Abstract

The invention provides a material separating mechanism used for artificial panel production. The material separating mechanism at least comprises a draught fan, air flues, a stock bin and a feeding device; the feeding device is connected with the draught fan through the air flue A, and the draught fan is connected with the stock bin through the air flue B; the air flue A is sequentially composed of a straight flowing area, a separating area and a telescopic area, wherein the straight flowing area is connected with the feeding device, the telescopic area is connected with the draught fan, the diameter of the separating area is larger than that of the straight flowing area and the telescopic area, and the bottom face of the separating area is a slope; impurities separated out of materials and unqualified materials slide into the bottom of the separating area in a concentrated manner along the slope, a waste material opening is formed in the bottom, and the impurities and the unqualified materials are discharged through the waste material opening; the telescopic area is formed through sleeved combination of an inner layer pipeline and an outer layer pipeline, and the length of the telescopic area is adjustable; and according to the material separating mechanism, existing equipment and power can be fully used, energy consumption is reduced, and the separating effect of the materials is improved.

Description

technical field [0001] The invention relates to a device for sorting impurities or unqualified coarse materials for materials such as shavings or fibers in the wood-based panel industry. Background technique [0002] Due to the wide application of wood-based panels, impurities such as iron and stones in the materials not only affect the quality and safe production of the panels, but also affect the safe operation of production staff and equipment, and even cause fire and explosion accidents. [0003] At present, the separation of shavings or fiber particle materials in the wood-based panel industry generally adopts special airflow separators, vibrating screens, rolling screens and other forms. Vibrating sieves and rolling sieves are mainly used to sort shavings or fibers through mechanical vibration or rotation. Due to the light weight of shavings or fibers, they form agglomerates, which affects the separation effect and efficiency of materials. Although the airflow separat...
