Product Description Bridge type stacking and reclaiming system for coal handling in circular stockyard Circular gantry scraper stacker and reclaimer is mainly used in building materials, coal, metallurgy, electric power, port, and other industries, and is mostly used to stack limestone or coal and other bulk materials. The cantilever of the stacker is equipped with a belt conveyor, which passes through the steel structure grid roof of the circular stockyard from the belt conveyor on the trestle, and the input materials complete the ring conical stacking through the belt conveyor on the cantilever of the stacker; The reclaimer completes the reclaiming work via three linking processes: traveling system, luffing system, and scraper system. The scraper reclaimer scrapes the materials into the conical hopper under the central column along the slope of the pile and outputs the materials through the vibrating feeder and underground belt conveyor.

Stacking steel structure, cantilever belt conveyorThe cantilever stacker takes the central column as the center, one end is the belt conveyor with cantilever steel structure, and the other end is the counterweight box. The middle stacking slewing part is connected with the central column by slewing bearing, and the stacker can rotate by meshing the pinion on the slewing driver with the gear on the central column. The materials entering the circular stockyard are unloaded at the head of the cantilever belt conveyor and directly stacked to the stockyard. The stacker rotates at a certain angle for slope stacking until it is stacked into an annular pile. There are two main structural types of cantilever stacker, cantilever fixed type and cantilever luffing type.Comparison of the two types of stackers:(1)The advantages of the fixed stacker are simple structure and low cost. The disadvantage is that when the lower part of the stacker is not stacked or the material pile is low, the difference is huge, and the dust in the stockyard is more serious (even with a spray system).(2)The luffing stacker uses the hydraulic cylinder to raise or lower the cantilever. Its advantage is cantilever can raise up and down according to the stacking height to reduce the material drop and avoid dust flying. As well, it can reduce the height of the central column and reduce the cost. The disadvantage is that the structure is more complex. 2. Gantry stackerThe gantry scraper reclaimer is mainly composed of gantry, traveling mechanism, reclaiming luffing mechanism, and scraper reclaimer. The gantry is the main component of the rotation, luffing, and load support of the scraper reclaimer. The scraper reclaimer is set under the gantry. The luffing mechanism adopts mechanical winch-type, and one end of the gantry is connected with the central column by a roller bearing, The other end is supported on the circular track on the upper part of the stockyard retaining wall, and the rotation of the reclaimer is driven by the traveling wheel on the circular track. The gantry reclaimer has a robust structure, and most of the weight of the gantry is borne by the retaining wall, which significantly improves the stress state of the central column and makes the operation more reliable.The traveling mechanism is composed of a driving wheel group, traveling electrical detection and control system, and lubrication system. Considering the requirements of two-way movement of the swing gantry under the most unfavorable conditions, two traveling wheels are used as the driving wheels. The wheelset is mechanically driven by variable frequency speed regulation. Stepless speed regulation of working travel speed and nonworking travel speed (to ensure the normal and safe operation of circular stacker reclaimer, set slow and fast speeds respectively according to the on-site operation conditions, i.e. working travel speed and nonworking travel speed). To ensure that the stress of the gantry is reasonable and the wheel pressure of each wheel group under the gantry is the same, the gantry is hinged with the two-wheel groups, and each hinge point adopts through shaft type. In addition, the joint bearing is used at the connection between the gantry and the walking structure to ensure that the gantry can automatically adapt to the change of track. The lubrication of each supporting bearing and hinge shaft of the traveling mechanism adopts grease centralized lubrication. 3. Scraper (1) The scraper reclaimer adopts a sprocket to drive the roller chain, and then the roller chain drives the scraper to reclaim. This method has large traction, small linear resistance, and durability. It is a reclaiming method integrating reclaiming and transportation.(2)The scraper is fixed on the double chain mechanism, and the sprocket is driven by the motor at the rear for circular movement. The scraper scrapes the materials at the lower part of the stacker into the conical hopper at the lower part of the king column.(3) The scraper adopts the folded plate structure with forwarding inclination on both sides, which is welded by steel plate and has sufficient strength and stiffness. There are scraping teeth on both sides of the scraper. This structure can cut the material laterally most effectively, and the scraper does not stick to the material and has no return. The scraper body and roller chain are connected by high-strength bolts, which are convenient for maintenance and disassembly. The chain can be divided into the built-in chain and an external chain according to the placement position of the roller. Compared with the built-in chain, the external chain has the advantages of low noise and maintenance-free(4)The scraper driving device is composed of a motor, reducer, hydraulic coupling, etc. The driving device is impact-resistant and convenient for maintenance. The driving device is equipped with electrical double safety and overload protection and is equipped with a good shock absorption device.(5) The tensioning device of the scraper reclaimer is set at the head sprocket. The tensioning device is hydraulic tensioning, with constant tension and easy operation and adjustment.
