Description
Technical field
The present invention relates to a kind of bag-turning pattern filtering centrifuge, relate in particular to the improvement of bag overturning machine structure.
Background technology
In bag-turning pattern filtering centrifuge, be typically German glycolylurea Cole centrifuge Co., Ltd and turn over bag filtration centrifuge (patent No. 91101702.X).In this centrifuge, comprise a rotary drum that is rotatably supported in the casing, turning filter bag is arranged in the rotary drum, rotary drum is by a hollow spindle driven rotary, be equipped with in the hollow spindle one with main shaft axial restraint and can axially movable shifting axle, shifting axle one end with turn over a bag base plate and fixedly connected, the other end is connected with helical axis and is provided with one and helical axis nut engaged, helical axis is driven by another motor, the rotating speed of control helical axis moves axially shifting axle with respect to the relation between the hollow spindle rotating speed in hollow spindle.The bag overturning machine structure of this patent adopts shifting axle and helical axis integrative-structure, realizes that by the hollow spindle of different motors drivings and the speed discrepancy of helical axis moving axially of shifting axle makes the filter bag upset, and operating mode control difficulty is bigger.Chinese patent 012224219 discloses a kind of transmission mechanism of bag-turning pattern filtering centrifuge, this transmission mechanism comprises a hollow driving shaft that is driven by active motor, and rotate synchronously with driving shaft and can axially movable shifting axle, this shifting axle and screw rod adopt the split docking structure, shifting axle one end docks with screw shaft by a thrust bearing, be combined with nut on the screw rod, nut is erected in another bearing of frame and by motor and drives rotation, driving screw rod moves axially, pass to shifting axle by thrust bearing and move axially, axial motion mechanism is separated with axial motion mechanism.Do not need to utilize speed discrepancy to realize axially-movable, reduced operating mode control difficulty.To drive the axial dimension of bag overturning machine structure of screw motion longer but this mechanism's shifting axle docks and establish in addition a rotating nut on frame with screw rod, causes the centrifuge overall structure not compact.
The technical problem to be solved in the present invention is, when axially-movable separates with circumferential movement when realizing turning over bag, dwindles the axial dimension of bag overturning machine structure, thereby makes centrifuge structure reasonable, overall compact.
Technical solution of the present invention, bag-turning pattern filtering centrifuge comprises a rotary drum that is rotatably supported in the casing, be fixedly connected by hollow spindle one end of Electric Machine Control and the bottom of rotary drum, a shifting axle rigidity is passed main shaft, rotate with speed with main shaft is circumferentially fixing, and can move axially with respect to main shaft, the shifting axle right-hand member is fixedlyed connected with the base plate of upset filter bag, when moving axially with respect to main shaft, shifting axle can and take or take back rotary drum out of with the filter bag upset, turning over pkt. flap can seal rotary drum: the shifting axle right-hand member is made male splined shaft, the matching spline cover is fixed on the right-hand member of hollow spindle, the left end periphery of shifting axle screws in the fairlead of a levogyrate inner thread, this fairlead slidably cooperates with the main shaft endoporus, shifting axle left end endoporus screws in the externally threaded nut of a dextrorotation and cooperates with the fairlead of levogyrate inner thread, and it is fastening with hexagon socket head cap screw, thread spindle is installed in the left end endoporus of shifting axle and is meshed with nut, the spline that the thread spindle left end is made in spline and the bearing cap matches, and bearing is positioned at the hollow spindle left end to thread spindle.
By a clutch is arranged, this clutch drives shift fork by cylinder separates or combination clutch friction plate by thrust disc between above-mentioned bearing and frame.
Effect of the present invention: adopt the engagement of nut and fairlead, nut drives shifting axle and makes axially movable structure, has shortened the centrifuge axial dimension widely, makes the centrifuge overall compact, and is rational in infrastructure
