The circular stacker and reclaimer is a continuous stacker and reclaimer that is installed in a spherical shed and uses a cantilever stacker and a scraper reclaimer that can rotate along a fixed central column for bulk material stacking and reclaiming operations respectively. Machinery is one of the key large-scale equipment in the cement plant. It can simultaneously or separately complete the limestone stacking, mixing and reclaiming operations, and plays a vital role in the pre-homogenization of limestone, stabilizing kiln conditions and clinker quality. .
The working place of this kind of machinery is in a closed spherical shed, which can solve the problems of loss and scattering of materials affected by wind and rain during the stacking and reclaiming process. It consists of three parts: a stacker, a reclaimer and a central column. The stacker and the reclaimer are two independent and non-interfering systems, which can carry out the stacking and reclaiming operations at the same time.
The stacker is mainly composed of a cantilever frame, a cantilever conveyor, a slewing bearing, a counterweight box, a driving device, etc. For the boom frame with pitching requirements, a hydraulic luffing mechanism needs to be added; the reclaimer is composed of scraper arm, chain scraper It is composed of plate, tower, hoisting mechanism, driving device and other parts. For the reclaimer that needs to mix materials evenly, a loosening rake mechanism needs to be added.
When designing and manufacturing the reclaimer, the strength, stiffness and stability of the whole machine under normal working conditions should be considered. Regardless of the working state or non-working state, the stacker and reclaimer should be in a stable state at various positions within the specified pitch range; the cantilever is not allowed to affect the stability of the whole machine within the specified pitch range. shock.
Under normal working conditions, the inclination of the conveyor and the structure of the carrier must prevent the material being conveyed from slipping or accidentally falling; the high-voltage electrical appliances should have a specified safety distance; Take dust-proof measures in the place where the dust is raised.
