Description

A kind of lifting gear for electrolytic bath anode and method

Technical field

The invention belongs to the aluminum electrolysis industry, be used for electrolyzer, relate to a kind of cathode lifting device and method, particularly a kind of cathode lifting device and method that need not the bus motion.

Background technology

On aluminium industry electrolyzer, anode large bus bar is hung on the electrolyzer by the bus drive unit at present, and the guide rod of anode block is pressed to by the spiral jig and makes it on the bus and the bus relative fixed.Along with the scaling loss of anode block, the bus drive unit will carry anode and descend, and when drive unit drops to ram bolster, just can't descend again, and need with other a kind of support equipment " positive bar switching framework ", hereinafter to be referred as anode superstructure this moment.With multifunction crane anode superstructure is sling, run to the electrolyzer top that needs to promote big bus, pressurized air is fed the anchor clamps cylinder anchor clamps jaw is opened; Aim at anode and be placed on the electrolyzer crossbeam, the back, location cuts off source of the gas and bleeds off the pressurized air in the cylinder, utilizes spring force to tighten up the anchor clamps jaw; Anode is hung, unclamp the spiral jig that is pressed on the anode then, make big bus and the anode can relatively sliding; Running bus drive unit is lifted to upper dead point with big bus; Again anode is pressed on the big bus with the spiral jig, makes it and big bus relative fixed, connect the source of the gas of anode superstructure anchor clamps cylinder then; Anode superstructure is opened and removed to the jaw of anode superstructure, and the bus drive unit just can carry anode to be continued to descend.This production technique and this bus drive unit continue use and have century-old history in whole electrolysis industry; All the time do not get rid of the constraint of anode superstructure; And switching process can produce various drawbacks: excessive like anode rod cross-sectional dimension deviation, cylinder leakage tester or potroom bleed pressure deficiency can cause anode superstructure can't be placed on the electrolyzer or be stuck in electrolyzer hanging oneself to get off; Spring failure or fracture can cause anode to be fallen into causing industrial accident in the electrolyzer; Processing parameter can change before and after the switching, need readjust processing parameter, and the electrolyzer technology stability is reduced; Lifting process causes easily between anode and bus and produces electric arc, can damage both contact surfaces, causes contact resistance to increase, and current efficiency is reduced; Need a plurality of workmans to operate simultaneously at every turn when promoting bus, take a multifunction crane simultaneously, very inconvenient.

Or described working mechanism comprises bracket III, steel hook, slideway III, arrangement of clutch III, tooth bar, gear unit, sprocket wheel and spiral jig, and the sprocket wheel in the working mechanism is connected through the sprocket wheel on the transmission shaft of chain and transmission rig, the pinion(gear) in the sprocket wheel in the working mechanism and the gear unit and handle is coaxial and relative fixed; Pinion(gear) in the gear unit and master wheel interlock, the tooth bar interlock on master wheel and the bracket III, bracket III slides in slideway III; Bracket III goes up the steel hook is installed; The spiral jig is pressed on anode on the bracket III, and bracket III is connected with big bus through the soft band of conduction, and arrangement of clutch III comprises that chimeric sliding sleeve, elastic force removes handle and shift fork; The transmission shaft of transmission rig drives chimeric sliding sleeve and rotates; Under the condition of arrangement of clutch III closure, chimeric sliding sleeve drives the sprocket rotation on the transmission shaft, starts building to do the sprocket rotation in the mechanism through the transmission belt of chain; Driving master wheel with the pinion(gear) of sprocket coaxiality in the working mechanism rotates; Master wheel drives tooth bar and does the motion that rises or fall together with bracket III, and anode is fixed on the bracket III, does the motion that promotes or descend thereby drive anode; Or described working mechanism comprises chain, sprocket wheel, bearing, bracket IV, axle, tubular shaft, steel hook, arrangement of clutch III and spiral jig; In the both sides of every transmission shaft two sprocket wheels are installed, two sprocket wheels connect into one-piece construction through tubular shaft and can on transmission shaft, freely rotate, and arrangement of clutch III is installed on the transmission shaft to be connected with chimeric sliding sleeve with sprocket wheel and transmits torque; Tubular shaft together with two sprocket wheels respectively with chain be installed in lateral two sprocket wheels of electrolyzer crossbeam and be connected; Be installed in the shared axle of lateral two sprocket wheels of electrolyzer crossbeam, the two ends of axle are connected fixing with the electrolyzer crossbeam through bearing, and bracket IV is installed on the chain; The steel hook is installed on the bracket IV; Anode is pressed on the bracket IV with the spiral jig, and bracket IV is connected to anode supply with big bus through conducting electricity soft band, and transmission shaft drives chimeric sliding sleeve and rotates; Under the condition of arrangement of clutch III closure; Chimeric sliding sleeve drives two sprocket rotation on the transmission shaft, and the transmission through two chains drives and is installed in lateral two sprocket rotation of electrolyzer crossbeam, does the motion that rises or fall so chain drives bracket IV; Anode is fixed on the bracket IV, does the motion that promotes or descend thereby drive anode.

2. method that adopts lifting gear for electrolytic bath anode as claimed in claim 1; It is characterized in that: the motor drives step-down gear of actuating unit rotates; Step-down gear drives transmission shaft and rotates, and transmission shaft is passed to working mechanism with power, and working mechanism drives anode lifting.
