Problems solved by technology

[0004] Due to the special structure of the circular stacker and reclaimer, it cannot be used to store raw coal in the center and upper part of the circular coal yard, resulting in a relatively large footprint, and the actual stacking capacity is only 30% of the designed stacking capacity about
In addition, the circular stacker-reclaimer may generate relatively large dust during scraper reclaiming, reloading point and belt stacking, and corresponding measures need to be taken to prevent it
[0005] For the control of dust generated during scraper reclaiming, transfer and blanking, spraying is commonly used to reduce dust, but in the case of water spraying, the humidity of raw coal will be increased, which cannot meet the owner's requirements for coal humidity

Abstract

The invention discloses a novel round coal field unloader. By means of the round coal field unloader, the floor space can be saved, no dust flying occurs, and meanwhile, the comprehensive cost of a round coal field is reduced. According to the adopted technical scheme, one or more umbrella-shaped flow guide devices are disposed on the inner side of the bottom of a round storage silo; material feeding channels are formed between the umbrella-shaped flow guide devices and the side wall of the round storage silo and / or between every two adjacent umbrella-shaped flow guide devices; a plurality of unloader bodies are symmetrically distributed at the bottom end of the round storage silo; material inlets of the upper portions of the unloader bodies communicate with the material feeding channels; material outlets are formed in the lower ends of the unloader bodies; every two symmetrically arranged unloader bodies share one material outlet; and scraper blade material taking systems and belt material feeding systems of the unloader bodies are located in material feeding machine shells, the scraper blade material taking systems and the belt material feeding systems are arranged in a split mode, materials are taken away by the scraper blade material taking systems from the material inlets, and then the materials are scraped through scraper blades to be put on the belt material feeding systems and then delivered to the material outlets. The round coal field unloader is widely applied to the field of unloaders.

Description

technical field [0001] The invention relates to a circular coal yard unloader, which belongs to the technical field of unloader equipment. Background technique [0002] At present, the stacking and unloading of circular coal yards are all realized by circular stackers and reclaimers. The circular stacker-reclaimer consists of three parts: the stacker, the reclaimer and the central column. The stacking and reclaiming operations are realized through the relatively independent operation of the stacking rotary mechanism and the reclaiming rotary mechanism. [0003] The stacker is composed of a cantilever belt stacker and a feeding belt conveyor, and the reclaimer is composed of a scraper reclaimer, a central conical hopper, and a discharging belt conveyor. The cantilever stacker rotates around the center column through the stacking slewing mechanism; the reclaiming scraper is supported by a half-gantry structure that spans the circular stockyard, and the other end of the mast i...
