Embodiment 1

[0031] Such as Figure 1-3 As shown, a closed coal yard includes a closed network frame, a feeding mechanism, a blanking mechanism and a reclaiming mechanism.

[0032] The closed network frame 6 is a strip arched sealing structure with a semicircular cross section. This closed structure solves the environmental pollution problem of the coal yard to the outside world. The cross-section is a semicircular structure, and the coal piles are symmetrically arranged on both sides with the center line as the symmetry line. From the perspective of the formation shape of the coal piles in the present invention, the coal piles formed in the semicircular space have the highest utilization rate and large reserves. The elongated arched structure can be extended freely in the length direction, so as to facilitate the expansion of the factory building and meet the requirements of the expansion of the site. It is especially suitable for large-scale coal storage and distribution base projects ...

Abstract

The invention discloses a closed coal yard comprising a closed net rack, a feed mechanism, a discharge mechanism and a reclaiming mechanism. The feed mechanism comprises a feed belt conveyor. The discharge mechanism comprises a stacker, a cantilever belt conveyor and a column. The reclaiming mechanism comprises a reclaiming belt conveyor and a scraper reclaimer. A feed yard belt conveyor and a stacking travel rail are arranged on the upper portion of the column. A reclaiming travel rail is arranged in the middle of the column. The stacker vertically moving along a coal pile is arranged above the feed belt conveyor; the feed belt conveyor conveys coal to the cantilever belt conveyor of the stacker. The scraper reclaimer regulates pitching angle thereof through a cable hosting mechanism according to the shape of the coal pile. The scraper reclaimer vertically moves along the coal pile through the reclaiming travel rail. The closed coal yard is high in storing capacity, convenient to continuously expand, high in automation level, small in floor area, and economical and energy saving; the closed coal yard is applicable to large storage and distribution coal bases and power plants continuously expanded.

Description

technical field [0001] The invention relates to a closed coal yard, belonging to the technical field of storage yards, which can be used in the electric power industry as a coal-fired power plant to store or transfer coal, and can also be used in mining industries with similar coal particle sizes. [0002] Background technique [0003] At present, there are mainly four types of fully enclosed coal yards that are common in China: 1. Closed bucket wheel coal yard, 2. Closed circular coal yard, 3. Closed spherical thin-shell coal yard, and 4. Large silos. [0004] Among them, 1. The closed bucket wheel coal yard occupies a large area, requires professional personnel to operate, and has a low degree of automation; therefore, it requires high-quality personnel, and the coal pusher has many auxiliary operations, which leads to high costs. [0005] 2. Closed circular coal yards are mature in application and have extensive performance, but the reserves of a single block are limited...
