A mechanical screening device

Abstract

The invention discloses a mechanical screening device. The mechanical screening device comprises a base. An equipment box is mounted on the base. A rotating shaft and rotating racks are mounted on the lower portion inside the equipment box. A rotating block is mounted on the rotating shaft. The cross section of the rotating block is in a regular-polygon shape. A poke rod is mounted on each face of the side rim of the rotating block. A rotating wheel is mounted at the end of each poke rod. A first rotating disc is mounted at the end of the rotating shaft. Multiple first mounting plates are mounted on the first rotating disc and uniformly distributed around a central shaft of the first rotating disc. First magnet blocks are fixedly mounted at the two sides of each first mounting plate correspondingly, wherein the cross section of each first magnet block is triangular. The two rotating racks are located on the side portions of the rotating shaft. A rotating barrel is mounted between the two rotating racks. A first motor is mounted on one of the rotating racks. A rotating shaft of the rotating barrel is connected with an output shaft of the first motor. A spiral protruding strip is arranged at the periphery of the rotating barrel. The rotating wheels on the poke rods are located among the spiral protruding strip. According to the mechanical screening device, screening is conducted in a swinging manner; the process is gentle; and the mechanical screening device is more suitable for materials which cannot be subjected to strenuous vibration.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, in particular to a mechanical screening device. Background technique [0002] At present, the existing screening machines often use high-intensity vibration in order to increase the efficiency of discovery. This method is too strong for some materials to contact with the filter screen, resulting in a high frequency of replacement of the filter screen and a short service life. There are more collisions between materials, and the contact frequency and surface area of ​​some materials with air will increase, and the oxidation rate will increase, which will affect the quality of materials. Contents of the invention [0003] The invention provides a mechanical screening device to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A mechanical screening device, including a base, on which an equipment box is install...
