Multi-layer integrated type series-connection vertical telescopic dry-process vibration medium drainage screen

Abstract

The invention discloses a multi-layer integrated type series-connection vertical telescopic dry-process vibration medium drainage screen. The medium drainage screen comprises a whole machine frame fixed on a support base, a left front-back movement track and a right front-back movement track; vertical supporting moving hydraulic cylinders are installed at the two ends of the upper portion of the left front-back movement rail and the two ends of the upper portion of the right front-back movement rail respectively, and a plurality of layers of screen frames and outer covers provided with screenmeshes are sequentially mounted on the inner side of the whole machine frame from bottom to top; the screen frame and outer cover of each layer comprises four damping devices, a screen frame and outercover body, a dense medium discharging channel and a clean coal and gangue outlet, wherein the screen frame and outer cover body is installed above cross beams arranged in the front-back direction and the left-right direction in the whole machine frame, four corners of the screen frame and outer cover body are located on the four damping devices correspondingly, and the dense medium discharging channel and the clean coal and gangue outlet are arranged at corresponding positions below the screen frame and outer cover body; and vibration motors are fixedly connected to the front sides and the rear sides of the screen frame and outer cover bodies, a screen telescopic power device and rotating shaft is arranged at a reserved position at the upper portion of one end of the screen frame and outer cover body of each layer, and a screen fixing device and rotating shaft is arranged at the reserved position at the upper portion of the other end of the screen frame and outer cover of each layer.

Description

technical field [0001] The patent of the invention relates to a vibrating sieve for heavy material recovery in the process of dry heavy medium separation, specifically, it is especially suitable for the multi-layer integrated series vertical telescopic dry method vibration of wet coal adhesion and heavy material removal and recovery Detachment sieve. Background technique [0002] my country's coal resources are mainly distributed in arid or semi-arid areas in the central and western regions, and the application of traditional wet separation technology is limited. For this reason, the National Development and Reform Commission, the Energy Bureau and other departments have clearly proposed in the "Energy Technology Revolution Innovation Action Plan (2016-2030)" to develop efficient dry coal preparation technology, and the air dense medium fluidized bed separation technology as The theoretically ideal high-efficiency dry separation technology has become a hot research topic at...

AI Technical Summary

Problems solved by technology

Some of the existing dry disengagement screens are also improved on the basis of the wet disengagement screen in the wet heavy medium separation process, which has the disadvantages of large floor area, high cost, high requirements for the plant, and poor separation effect. Ideal and other issues
