Suspension type dish-shaped coupling vibrating screen classifier

Abstract

The invention discloses a vibrating screen classifier, and particularly relates to a suspension type disc-shaped coupling vibrating screen classifier which is characterized by comprising a fixed beamwith disc-shaped springs I at the two ends; a motor frame fixedly provided with a motor with a rotary eccentric block and a belleville spring II; and a screen box which is provided with a first hanging rod and a second hanging rod. The belleville spring II is connected with a belleville spring I aligned right above the belleville spring II through a steel wire lifting rope; the first hanging rod is fixedly connected with the belleville spring II aligned to the position over the first hanging rod, and the second hanging rod is fixedly connected with the belleville spring II aligned to the position over the second hanging rod; and the rotation frequency of the rotary eccentric block equals the inherent frequency of the screen box. The vibrating screen has the characteristics of high use reliability, high screening efficiency, energy conservation and the like.

Description

technical field [0001] The invention discloses a vibrating screening machine, in particular to a suspended disc-shaped coupling vibrating screening machine. Background technique [0002] The vibrating screen uses the principle of mechanical vibration to make the material be thrown up on the screen surface, and at the same time move forward in a straight line to make a reasonable matching screen to achieve the purpose of screening. Therefore, using a vibrating screen to classify the mixed large and small particle materials is a common classification method in industry. [0003] Working on the principle of vibration, in theory, the power consumption is smaller than other forms of material classification, and the production capacity is large. Therefore, vibrating screens are not only widely used in mine beneficiation and screening, but also in other industrial and agricultural production industries for screening materials of various sizes, or for dehydration, desliming and de-...

Problems solved by technology

There is also a kind of suspended vibrating screen (publication number: CN103639113A) similar to the structure of this kind of suspended sieving machine; the common shortcomings of these two structural forms are: (1) the vibrator and the screen box are fixed Working and vibrating together will increase the vibration load of the screen box, correspondingly increase energy consumption, and shorten the life of the vibrator; (2) When the motor drives the vibrator, it will generate traction force, which will make the screen box and the connection with the screen box The spring components are subjected to additional pulling force, which increases the load on the screen box and spring components

There is also a Chinese patent with a wide-width suspended vibrating screen (notification number: CN204638514U). Although the screen box of this kind of structure is also a suspended structure, this kind of vibrating screen is a swing type screening, and the screen box is in a vertical mode. no vibration
