Screen tower and screening building distribution structure

Abstract

The invention relates to bulk material conveying, in particular to a screen tower and a screen tower distribution structure. The screen tower comprises a supply device, a distribution device, screening devices and conveying device, wherein the supply device comprises a belt conveyor; the distribution device comprises a plurality of plow discharger matched with the belt conveyor to unload materials. The coulter lifting height of the multiple plow dischargers is sequentially decreased in the conveying direction of the belt conveyor so that the materials at different height positions can be unloaded. The screening devices are connected to the lower portions of the plow dischargers and used for receiving materials. The conveying devices are connected with the screening devices and each comprise a coarse material conveying device for conveying coarse materials and a fine material conveying device for conveying fine materials. By means of the technical scheme, the requirement for screening and conveying a large amount of coal at the same time is met, and the requirement of a screening and conveying system of a multivariate coal chemical industry device is met.

Description

technical field [0001] The invention relates to bulk material transportation, in particular to a screening building and a material distribution structure of the screening building. Background technique [0002] At present, in the coal chemical industry, when the existing coal conveying system is used to transport materials for coal chemical equipment, the granularity of coal required by different equipment is different. The gasification unit only accepts coal with a particle size of less than 6mm. In this case, it is necessary to screen the incoming coal, and then transport the coal with different particle sizes through multiple independent conveying systems. For the coal of the multi-component coal chemical plant The chemical system, the material screening and conveying system has a large space and requires a large number of equipment. At present, there is no coal screening building that can realize unified screening and conveying for multiple coal chemical plants. Conten...
