Vibrating type bar screening equipment

Abstract

Vibrating type bar screening equipment comprises a frame; two side plates and a rear baffle are arranged at the upper end of the frame; the front ends of the two side plates are large material discharging ends; a vibrating frame is arranged at the peripheries of the two side plates and the rear baffle, and is supported by a vibrating support frame in a floating manner through a plurality of damping springs; vibrating motors, a first shaft and a second shaft are mounted on the vibrating frame; the first shaft and the second shaft penetrate the two side plates and are arranged up and down; a plurality of short bars are mounted on the first shaft to form an upper bar screen; a plurality of long bars are mounted on the second shaft to form a lower bar screen; a kick-off drum comprising a drum body and groups of kick-off teeth is arranged at the positions of the large material discharging ends; striker plates are respectively arranged at two ends of the kick-off drum; the kick-off drum is supported by the frame; a driving mechanism is arranged outside the side plate on one side; and the long bars are suspended and inserted one by one between the kick-off teeth arranged axially on the kick-off drum. The vibrating type bar screening equipment has the advantages that the service lives of the bar screens are prolonged, the excitation force, the vibration frequency and the power of the vibrating motors are reduced, and the discharging speed of large materials on the bar screens is increased.

Description

technical field [0001] The invention relates to classification treatment equipment for blocky and medium and small particle materials, in particular to a vibrating bar screening equipment. Background technique [0002] In the field of material classification and processing, the existing vibrating bar screening equipment has a single-layer bar sieve structure, and the whole machine vibrates with the material during operation. In this way, the exciting force and power of the vibrating motor are required to be large. , and in order to speed up the discharge of the large material on the bar screen, it is necessary to increase the angle of the bar and the vibration frequency of the motor. The increase in the angle of the bar will lead to an increase in the potential energy of the blanking, which will cause more damage to the bar screen. Large impact will reduce the service life of the bar screen. Contents of the invention [0003] In order to solve the technical problems exist...
