Three-machine-driving double-mass-body subresonance self-synchronizing probability constant thickness screen and parameter determining method

Abstract

The invention discloses a three-machine-driving double-mass-body subresonance self-synchronizing probability constant thickness screen which is mainly applied to industrial and mining enterprises. Double mass bodies of the three-machine-driving double-mass-body subresonance self-synchronizing probability constant thickness screen are of a novel structure, one mass body drives the other mass body, so that a sensitive subresonance system is formed, and the overall mechanical performance is affected by variation of loading capacity. Compared with a single-mass-body system, a double-mass-body system can achieve the same effect by smaller power. Compared with a traditional single-stage system and a double-stage system, the driving frequency is improved, screening is more complete, and the working efficiency is further improved. Three different coupling vibration exciters have the same rotating direction, so that self-synchronous driving is achieved, and energy saving is achieved. Through application of a probability constant thickness screen theory, probability quick layering, screen blockage preventing and constant thickness high-efficiency screening of materials on a machine body are achieved, the screening efficiency and the yield are improved, and large-scale screening machines are achieved. Three-machine self-synchronizing driving is adopted to improve the uniform distribution of exciting force on a screening machine.

Description

technical field [0001] The invention belongs to a modern vibrating screening device, and relates to a three-machine-driven two-mass sub-resonance self-synchronizing probability equal thickness screen. Background technique [0002] In the field of modern screening machinery technology, vibrating screens are widely used in industrial and mining enterprises, and are used for screening, grading, washing, de-intermediation and dehydration of materials. The level of screening technology and the quality are related to the quality of the process, the level of production efficiency and the degree of energy saving, which directly affects the economic benefits of the enterprise. Generally, vibrating screens have low screening efficiency and long screening time, and the vibrating screen mechanism is too traditional to realize large-scale equipment. As a new concept of current screening machinery, vibrating screens are required to be structurally different from the original screening mac...

AI Technical Summary

Problems solved by technology

[0004] 1. Traditional vibrating screens generally use single-machine drive or double-machine synchronous drive. The motor power required is large, and energy consumption increases. The volume of the motor itself is also large, and the technical requirements for the motor are also increased.

[0005] 2. The traditional vibrating screen usually adopts a single body, which is very difficult to realize large-scale equipment. The dynamic load transmitted to the foundation is relatively large, and the strength requirements for the vibrating screen itself are particularly high.

[0006] 3. The traditional vibrating screen generally adopts a gear-driven forced-contact vibrator. Although the structure is compact and the cost is low, due to the high vibration frequency and large amplitude of the vibrating screen, the machining accuracy and lubrication requirements of the gear are particularly high.
