Description
Technical field
This utility model relates to a kind of stiffening ring cold slewing frame.
Background technology
Central cooler is key equipment widely used in sintering process flow process.After central cooler is arranged in sintering machine in technological process, for sintering the cooling of heat material.Sintering hot mineral aggregate coolant mechanism in central cooler rely primarily on cold wind blast bed of material heat exchange on chassis realize hot mineral aggregate cooling.
Some chassis it are disposed with annular frame circular flow on the annular horizontal track of central cooler.In material feeding position, feed chute, sintering heat material falls into chassis continuously, forms the bed of material that certain thickness is evenly distributed.Chassis bottom is provided with bellows, and ventilating system is sent into cold air and entered bellows, and cold air overcomes materialbeds comminution under pressure, penetrates the sintering heat material on chassis and carries out heat exchange therewith and take away heat；Heat sinter on chassis runs through certain time on circular orbit with chassis, sintering heat material is cooled to the discharge temp of technological requirement, after arriving unloading part, the bearing material mesa structure of chassis rotates around the fixing hinge of chassis, implement tumble action and the mineral aggregate after cooling on table top is discharged into lower panel ore deposit machine chute during advancing along the bend track below horizontal rail, by plate ore deposit machine, sintering deposit is transported to finished belt machine again, is delivered to finished product clearing system by finished belt machine further.Chassis after discharging rises along bend track and implements restoring action, then continues to move ahead；Empty wagons prepares to accept sintering heat material again.Chassis on annular frame has constantly circulated the task that technological process specifies along track.
In central cooler, chassis is in the horizontal rail circular flow of annular, tumbles action at unloading part simultaneously, therefore, has rubber sealing structure, commonly referred to as static seal between chassis itself and chassis；Motion seal between chassis group side building enclosure and air, commonly referred to as movable sealing.
In tradition central cooler, major part uses rubber movable sealing structure.Come into operation after a period of time, general rubber movable sealing structure can cause the problems such as the chassis tear in caulking gum excessive wear, rubber weather strip meeting passive movement due to factors such as chassis sideslip, too high, the mineral aggregate granule mounting boards of operating ambient temperature, make central cooler lateral movement seal failure, considerably increase energy dissipation.Tradition central cooler air leak rate of air curtain is relatively big, and generally 30%～about 40%, energy utilization rate is the highest, there is bigger energy waste.Meanwhile, leak out the mineral aggregate granule severe contamination site environment that place blows out with positive pressure air；And owing to hot blast spills so that central cooler peripheral temperature raises, cause the deterioration of working environment.
For a long time, professional and technical personnel is devoted to exploitation always and solves the key technology of movable sealing, solves central cooler Air Leakage.Central cooler evolution occurs in that multiple lateral movement Sealing Technology, such as: " water-stop ", " labyrinth seal structure ", " soft magnetic seal technology " etc..Although these improve effectively raise Sealing Technology, improve waste heat recovery usefulness, reduce mineral aggregate granule pollution on the environment deteriorate, but the most fundamentally solve central cooler there is sealing the essence of the best problem.
Central cooler sideslip during gyration is the key factor affecting its movable sealing effect, and sideslip depends primarily on the bulk deformation degree of central cooler revolving body.Existing general central cooler revolving body framework the relatively low central cooler revolving body that do not reaches of rigidity in motor process, occur without the requirement of sideslip, and be spliced owing to existing central cooler revolving body uses tens pieces of straight line templates, owing to link position is more, further result in revolving body bulk deformation degree to increase, thus occur that central cooler revolving body deforms, cause the problem that central cooler sideslip occurs in gyration process.
