Problems solved by technology

At present, most powder screening machines are vibrating machines, which generate serious dust floating, which affects the production environment and sanitation conditions of enterprises, and the output is low and the operation is complicated.
In addition, there are generally two technical defects in various agricultural and forestry waste crushing and screening machines: 1. The traditional screening machine uses the mechanical principle of the brush, and the brush will squeeze and rub the screen. Standards affect product quality, and are likely to cause friction damage to brushes and screens, requiring frequen

Abstract

The invention discloses a plant fiber sizing screen powder machine, and belongs to the technical field of sifting machines. The plant fiber sizing screen powder machine comprises a rack and a machine shell, wherein the machine shell is formed by a front standing plate, a rear standing plate, a top shell and a bottom plate, and the machine shell is provided with a screen door; a screen drum is fixed between the front standing plate and the rear standing plate, the screen drum comprises front and rear end drums, a screen mesh frame and a screen mesh, the screen mesh comprises a first order screen mesh and a second order screen mesh, and the screen holes of the second order screen mesh are greater than that of the first order screen mesh; and the screen drum is internally provided with a pneumatic conveying device, the upper part of the machine shell is provided with a feeding bin, the lower part of the machine shell is provided with a first order discharge hopper and a second order discharge hopper, and the rear part of the machine shell is provided with a rear discharge port. The plant fiber sizing screen powder machine provided by the invention is used for screening plant fiber power, the structure that a screen drum is fixed and screen mesh is sectionalized is adopted, and the pneumatic conveying device is utilized to deliver powder; and the screening thing uniformly passes in a screening process, the liquidity is strong, the fractionation effect is good, and the output and the quality of the products are notably improved.

Description

technical field [0001] The invention relates to a fiber powder screening machine, which belongs to the technical field of powder screening machines. Background technique [0002] Agricultural and forestry wastes include farmland wastes (such as straws), garden wastes (such as branches) and forest product wastes. The use of these wastes through crushing and milling has good economic and environmental benefits. At present, most powder screening machines are vibrating machines, which generate serious dust floating, which affects the production environment and sanitation conditions of the enterprise, and the output is low and the operation is complicated. In addition, there are generally two technical defects in various agricultural and forestry waste crushing and screening machines: 1. The traditional screening machine uses the mechanical principle of the brush, and the brush will squeeze and rub the screen. Standards affect product quality, and are likely to cause friction da...
