Abstract

The invention discloses a floating frame driving type flip-flop screen. The flip-flop screen comprises a fixing screen frame, a floating screen frame, an elastic screen surface, a shearing spring and an eccentric vibration exciter, wherein screen surface cross beams of the fixing screen frame and screen surface cross beams of the floating screen frame are alternatively arranged, the number of the screen surface cross beam of the fixing screen frame is greater than that of the screen surface cross beam of the floating screen frame by one, one end of the elastic screen surface is fixed on the screen surface cross beams of the fixing screen frame, the other end of the elastic screen surface is fixed on the screen surface cross beams of the floating screen frame, the two screen frames are connected together through the shear spring, and the fixing screen frame is installed on the rack through a damper spring. The eccentric vibration exciter has an eccentric block or eccentric shaft structure, a rotary shaft or an eccentric shaft are installed on the screen surface cross beam nearby the centroid of the floating screen frame. The flip-flop screen has a simple structure, low energy consumption, low vibration exciter stress and low failure rate and is particularly suitable for dry deep screening of wet fine coals of a coal preparation plant and also suitable for dry deep screening of other types of materials.

Description

technical field [0001] The invention relates to a dry depth screening device, in particular to a floating frame driven relaxation screen, which is especially suitable for the dry depth screening of wet fine coal in coal preparation plants, and also suitable for the dry process of other types of materials. Depth screening. Background technique [0002] The use of vibrating screens to separate coal has become an indispensable equipment for coal preparation plants. Since wet fine-grained viscous materials are easy to agglomerate and block the sieve holes, their sieving has always been a difficult problem in dry sieving. The relaxation screen effectively solves the screening problem of wet fine-grained viscous materials, but the traditional relaxation screen has complex structure, high energy consumption, large vibration exciter force, and high failure rate. Contents of the invention [0003] The object of the present invention is to provide a floating frame-driven tension s...
