Miscanthus floridulus stalk leaf removing and surface layer processing device and method

Abstract

The invention discloses a miscanthus floridulus stalk leaf removing and surface layer processing device, which comprise a motor, a transmission part of the motor, a machine frame and working rollers symmetric up and down, wherein the working rollers consist of delivering rollers (1, 2, 6 and 9) and at least three pairs of steel brush rollers (4, 5 and 7); the roller diameter is 150 to 400 millimeters; the steel wires in two adjacent circles on the same steel brush roller are alternately arranged; the steel brush rollers comprise a pair of roughly leaf removing steel brush rollers (4), a pair of finely leaf removing steel brush rollers (5) and 1 to 3 pairs of waxing and silicon removing steel brush rollers (7) in turn in the advancing direction of the raw material; and the two ends of the roller shaft (11) of each roller are provided with elastic devices which are arranged on the machine frame together, and a pneumatic dust hood (8) is arranged on the rear side of each steel brush roller. The miscanthus floridulus stalk leaf removing and surface layer processing carried out by the device are implemented by the productions steps of material selecting and drying, raw material selecting and wax and silicon removing, and defibering the surface layer. The device provides an important production process technical support for reducing the ecological damages of the miscanthus floridulus stalks and partially relieving artificial board raw material shortage.

Description

technical field [0001] The invention relates to a device and a method for pretreating the surface layer of the raw material before making glued materials by using the stem of the perennial Gramineae herbaceous plant Pentaphyllum as raw material. Background technique [0002] Miscanthus floridulu (Labnll) Warb is a perennial herbaceous plant of Gramineae. Its stem is more than 2m high and 0.5-1.5cm thick. The surface layer is rich in wax and silicon. The leaves are lanceolate and alternate. The length is 25-80cm, and the leaf width is 1.5-4cm. The surface layer of the five-section mans stem (hereinafter referred to as the mans stem) is mainly composed of lignin. Substances, mango stems contain a certain amount of sugar, starch and protein. Due to the above-mentioned structural characteristics of awns stalks that are different from those of wood, bamboo, wheat straw, straw, cotton stalks, bean stalks, and flower stalks, it is necessary to use unique devices and methods to rem...
