Description
Technical field
The invention belongs to lateral deviation device technique field, especially relate to a kind of central cooler revolution body examination deflection device and measuring method thereof.
Background technology
Domestic current chain grate-rotary kiln acidic oxidation pellet production line, all taking drying grate, rotary kiln, central cooler as main equipment.150m
2central cooler is one of visual plant of acidic oxidation pellet production line, by gearing, solid of revolution, backing roll, pressure rail, side blocking roller, frame, bellows, feed hopper and unload ore bucket etc. and form, its effect is that rotary kiln is discharged to pellet (approximately 1200 DEG C of the temperature after gravity flow screen sifts out, FeO content is lower than 8%), by the even cloth of hopper (thickness of feed layer 800mm) on solid of revolution chassis, pellet is cooled on chassis, and (FeO is further oxidized, content is down to below 1%), temperature drops to below 150 DEG C.
The running of central cooler solid of revolution is to drive chain on fixing solid of revolution to complete by the hinge wheel of central cooler two final drive gears, and solid of revolution is placed on the backing roll of interior ring and outer shroud, backing roll contacts with solid of revolution upper support track, and supporting track and siding track are installed on solid of revolution.In solid of revolution operation process, radial location is completed by 18 side blocking rollers of interior ring, is provided with standard clearance L between siding track and side blocking roller.When solid of revolution running radial deflection is greater than while being provided with standard clearance L, side blocking roller contacts with siding track, side blocking roller rotation.When solid of revolution is during because of cloth inequality, backing roll unbalance stress, solid of revolution skew is overproof excessive, and the extruding force that side blocking roller is subject to increases, and side blocking roller will damage, and causes central cooler to stop.
The side-play amount of solid of revolution in the past, can only check the gap between siding track and side blocking roller, rule of thumb judges the stressing conditions of side blocking roller, can not effectively detect solid of revolution real offset problem.
