Abstract

The invention relates to a centrifugal sieving machine which comprises a machine base and a sieving box, wherein a central shaft is vertically mounted at two ends of an upper feed inlet and the lower machine base in the cylindrical sieving box by using a bearing seat, a multi-layer material distribution disc which is distributed like a tower is mounted in the sieving box on the central shaft from top to bottom, fan blades are respectively symmetrically mounted at an outer ring of the material distribution disc in the sieving box by using disc seats at the upper end and the lower end of the central shaft, a layer of filter mesh is mounted on the upper inner wall and the lower inner wall of the sieving box on the outer side of the fan blades by using a net frame, a coarse material outlet and a fine material outlet which are respectively communicated with the interior and the exterior of the filter mesh from the bottom parts are arranged on the machine base at the lower part of the sieving box, a driving motor is arranged on the machine base on one side of the sieving box, and a transmission mechanism is connected between an output shaft of the motor and the outer end of the lower part of the central shaft. The centrifugal sieving machine has the advantages of simple structure, high sieving efficiency, low cost and low noise, and can be applicable to sieving materials with various specific weights.

Description

Technical field: [0001] The invention relates to a screening machine, in particular to a centrifugal screening machine suitable for screening fibrous materials with light specific gravity, easy to generate static electricity and good filling performance. Background technique: [0002] There are many kinds of existing screening equipment, such as vibrating screens, airflow screens, rotary vibrating screens, etc., which mainly use vibrators to screen materials on screens of different specifications according to different classification requirements. This type of equipment is suitable for screening materials with large specific gravity, but not suitable for screening fibrous materials with light specific gravity, easy to generate static electricity and good filling performance. Invention content: [0003] The purpose of the present invention is to provide a centrifugal screening machine not only suitable for general materials, but also suitable for screening fibrous materials...
