Abstract

The invention provides an energy-saving, highly-efficient and microvibration-type fine linear sieving machine, which solves the technical problems of low sieving efficiency, short life of a screen, higher consumption on electricity required by sieving, and the like in the traditional sieving machine. The linear sieving machine comprises a stander, a feeding port, a coarse powder outlet, a screen, a screen frame for fixing the screen and a vibrating screen bottom, wherein the vibrating screen bottom is fixed below the stander and is provided with a fine powder outlet; the feeding port is formed above the stander; the coarse powder outlet is formed at one side of the stander; the screen frame is provided with shock-absorption spokes capable of reducing the screen surface amplitude of the screen; and a high-frequency micro-amplitude microvibration device is arranged on the vibrating screen bottom. Compared with the traditional linear screen, the traditional rotary vibration screen and the traditional rotary vibration screen having the ultrasonic cleaning function as well, the energy-saving, highly-efficient and microvibration-type fine linear sieving machine disclosed by the invention has the advantages that: on the premise of same powder sieving flow (such as 80Kg / h), the Newton efficiency of sieving can be increased to be above 90 percent from the original 30-70 percent, the service life of the screen is prolonged by more than 10 times, and the energy consumption of electric power required by sieving is only 7-15 percent of the original electric power consumption.

Description

technical field [0001] The invention relates to a device for separating powders of various granular materials according to their sizes, and belongs to the field of fine powder screening. Background technique [0002] Sieve screening is a technology or equipment that disperses powder particles of different sizes with mechanical energy, and then uses a screen to separate coarse and fine particles. This technology and related equipment are widely used in powder processing industry, such as food, chemical industry, mineral processing, powder metallurgy, pharmaceutical and other industries. Generally, there are two types of screening equipment for large-scale industrial applications, namely linear screens and rotary vibrating screens, summarized as follows: [0003] 1. Linear vibrating screen [0004] The existing linear vibrating screen is applied to the screening of coarse grain materials, which is driven by double vibrating motors on both sides of the screening machine. Wh...
