Vibration non-mesh screening machine

Abstract

The invention discloses a screenless vibration sieving machine, which comprises a vibration motor (1), a vibration sieve body (2), a screenless feeding plate (3) and screenless sieving plates (4), wherein a right part and a left part of the vibration sieve body are provided with a feeding port and a discharging port respectively; the feeding port end of the inside of the vibration sieve body is provided with the screenless feeding plate, the other part of the inside of the vibration sieve is provided with a plurality of screenless sieving plates upwards in an inclined direction; and the bottom of the vibration sieve body is provided with a plurality of vibration isolation devices (8); and a lower part of the screenless sieving plate is provided with a graded discharging port (10). The sieving machine applies composite rectilinear vibration produced by two vibration motors to the vibration sieve body so that materials of different weights are separated into different piling areas according to the throwing distance under the working condition of composite rectilinear vibration so as to realize material grading and sieving of fine and ultra-fine materials. The sieving machine comprises various innovative technologies, provides an absolutely novel design for sieving equipment, and makes outstanding contribution to the technological promotion of sieving equipment.

Description

technical field [0001] The invention relates to screening and grading equipment for materials, in particular to a vibrating screenless screening machine for screening and grading fine and extra-fine materials. Background technique [0002] Screening operation is to screen materials into different particle sizes to meet the requirements of different industries for materials. In industries such as metallurgy, iron and steel, chemical industry, energy, mining, coal, light industry and grain processing, a large number of screening equipment with different structures are needed to complete the screening of materials, which is also to meet the needs of all walks of life. important equipment. [0003] In the material screening operation, the traditional screening machinery does not separate from the mesh (such as square hole mesh, round hole mesh, strip hole mesh, special-shaped hole mesh, etc.) to complete the material screening. Screening equipment with mesh is limited by the m...

AI Technical Summary

Problems solved by technology

Screening equipment with mesh is limited by the manufacturing of sieve apertures, and it is impossible to make a screen with a particularly small aperture; even if the aperture of the screen is small, it is easy to cause material blockage and material failure when screening fine or ultra-fine materials. Through the sieve holes, it is difficult to sieve the material, and even the sieving operation of the material cannot be realized.

For the multi-layer screen device with different apertures required for material classification, the defects of this device are: first, it causes the complexity and bulky structure of the screening mechanical equipment, second, it has high cost and energy consumption; During the process, the screen needs to be replaced and repaired frequently, thus increasing the cost of equipment use and the difficulty of maintenance
