Efficient vibrating screen

Abstract

The invention discloses an efficient vibrating screen. The efficient vibrating screen comprises a shell, and a screening part and a vibrating part arranged in the shell, wherein a feed port is formed in the top of the shell; a first screening port, a second screening port and discharge ports are formed in the side of the shell; the vibrating part comprises a vibrating box, and a driving motor in driving connection with the vibrating box; the vibrating box and the driving motor are mounted on a base frame in the shell; a damping spring is additionally arranged on the base frame; the screening part is arranged on the upper surface of the vibrating part, and comprises a first rough screening net, a second rough screening net and a third fine screening net; all the screening nets are correspondingly connected with all the discharge ports in sequence; a height adjuster is additionally arranged on the screening part, and is arranged on the shell; and the inclined angles of the three screening nets can be adjusted through the height adjuster. Further, the apertures of the first rough screening net, the second rough screening net and the third fine screening net are reduced in sequence. Further, the driving motor adopts a variable frequency motor; and the vibrating amplitude of the vibrating screen can be adjusted through the variable frequency motor. Compared with the prior art, the efficient vibrating screen has the advantages of better screening effect and simple operation.

Description

technical field [0001] The invention relates to material screening equipment, in particular to a high-efficiency vibrating screen. Background technique [0002] In the existing vibrating sieve, two layers of screens are usually arranged, that is, a coarse screen located above and a fine screen located below, for screening materials layer by layer. However, for strip materials, although its length is greater than the aperture of the coarse screen, its cross-sectional size may be smaller than the aperture of the coarse screen, so it may fall through the aperture of the coarse screen to the fine screen, reducing the screening effect. .

Problems solved by technology

However, for strip materials, although its length is greater than the aperture of the coarse screen, its cross-sectional size may be smaller than the aperture of the coarse screen, so it may fall through the aperture of the coarse screen to the fine screen, reducing the screening effect.

For example, in the processing of modified plastics, two or more raw materials are usually melted, blended, extruded, and granulated. Qualified slices and plastic powder, when using the vibrating screen with the above two layers of screens to sieve granular materials, slices and plastic powder, unqualified long slices will relatively easily pass through the coarse screen and enter the silo for screening. Less efficient and ultimately affects the collection of particulate material and the quality of the final product
