Abstract

The invention discloses a rotary screening machine which is used for grading materials according to particle sizes. The rotary screening machine mainly comprises a machine frame, a screen frame, a screen net, a feeding pipe, a gear motor and a central shaft, wherein the screen net can rotate with the central shaft. The rotary screening machine is mainly characterized in that a feeding screw is placed inside the feeding pipe, screen barrel spoilers are placed on a section, locating inside the screen net, of the central shaft, and both the feeding screw and the central shaft are driven by the gear motor. The screen barrel spoilers face towards the direction of the feeding pipe and are slantly and sequentially installed on the central shaft from top to bottom in a stagger mode. When the feeding screw rotates, the materials are continuously delivered into the screen net along the direction of screwing, and the materials do axial motion and at the same time rotate around the central shaft inside the screen net with the screen barrel spoilers. The rotary screening machine is large in screening energy and screened materials are even. The rotary screening machine is simple and compact in structure and small in floor space.

Description

technical field [0001] The invention relates to a solid material screening machine, in particular to a rotary screening machine. Background technique [0002] The screening machine uses the relative movement between the granular material and the screen surface to make some particles pass through the sieve holes, and the sand, [0003] Gravel, crushed stone and other materials are divided into different grades of mechanical equipment according to particle size, and are widely used in pharmaceutical, food, chemical and other industries. Currently commonly used screening machines include vibrating screening machines, reciprocating screening machines, and spiral drum screening machines. The screening machine for processing materials in the prior art has the following defects: 1) there is no seal, and the dust in the screening process is too large, causing environmental pollution; 2) the equipment occupies a large area and the manufacturing cost is high; 3) the screening energy ...
