Total amplitude supporting high-frequency linear vibrating screen

Abstract

A total amplitude supporting high-frequency linear vibrating screen belongs to the field of vibrating screening machinery and mainly solves the problem that the existing high-frequency vibrating screen is insufficient in vibration frequency and can not meet production requirements. A plurality of sections of screen cloth are arranged on a screen cloth bracket transversely in a tightening mode in an arc shape, two vibrating devices or vibrating motors are arranged on horizontal and vertical vibrating device base plates in the middle of a vibrating beam, and a vibrating resultant action line passes through the gravity center of a screen box. The screen box is connected with a total amplitude elastic supporting base on a base support through four square trunnions. The total amplitude elastic supporting base is composed of an upper support, a lower support and rubber springs, and the square trunnions are arranged between an upper rubber spring and a lower rubber spring. The base support is connected with a base through a secondary damping device. A sealed slurry material box is arranged at the feeding end of the screen box on the base support. The total amplitude supporting high-frequency linear vibrating screen has the advantages of being high in vibrating frequency and large in vibrating strength and material screening productivity and the like, can be widely applied to precise screening of milled powder of an iron mine ball mill, fine-mesh-level wet materials like petroleum drilling slurry, coal and chemical-mesh-level materials.

Description

technical field [0001] The invention belongs to the field of vibrating screening machinery, and mainly relates to a full-amplitude supporting high-frequency linear vibrating screen with linear vibration track, high-frequency vibration and screening fine-meshed viscous materials. Background technique [0002] The high-frequency vibrating screen is the main equipment for screening viscous materials. Due to the limitation of the structure and vibration mode of the existing high-frequency vibrating screen, it is difficult to increase the vibration frequency and cannot achieve real high-frequency vibration. It is difficult to improve the screening efficiency and production capacity of the thick material vibrating screen. The Chinese patent "Vibrating Beam Type High Frequency Vibrating Screen", the patent number is ZL200720015951.1, has the characteristics of high screening efficiency and large processing capacity. Due to the shortcomings of large occupied space and the inability...

Problems solved by technology

Due to the shortcomings of large space occupation and the inability of the vibration motor to achieve linear vibration track screening in the vibrating beam, its development in the field of screening is limited.

The Chinese patent "Linear Vibration Vibrating Beam Type High Frequency Vibrating Screen", the patent number is ZL201020010257.2, the screen machine has multiple vibrating beams, in the implementation, it is necessary to work on the amplitude, vibration frequency and vibration direction angle of each vibrating beam in the horizontal state. The parameters are adjusted, and it is difficult for the vibrating screen to realize the synchronous vibration state of multiple vibrating beams under the condition of high-frequency vibration
