Driven voller opposite side at vacuum filter is provided with bearing block A1, has guide groove on the bearing block A1, has guide rail 2 on the bearing block A1, and bearing block A1 can slide on guide rail 2 freely.Connect by hold-down nut 3 between trapezoidal screw 4 and the bearing block A1, by bolting, be fixed between trapezoidal screw 4 and the bearing block A1 between trapezoidal screw 4 and the hold-down nut 3, trapezoidal screw 4 can't rotate.Open a through hole on the vacuum filtration machine support, trapezoidal screw 4 be able to pass this through hole.Bearing base plate 5 is welded on the filter support, pass through bolting between bearing block B6 and the bearing base plate 5, be provided with radial thrust bearing 7 in bearing block B6 inside, on trapezoidal screw 4, be provided with screw drive axle sleeve B19, screw drive axle sleeve B19 one end is fixed on ring in the radial thrust bearing 7, and screw drive axle sleeve B19 is pressed on the radial thrust bearing 7, and screw drive axle sleeve A8 can only rotate on trapezoidal screw 4 like this.Be provided with manual wrench 20 on screw drive axle sleeve B19, the people can drive screw drive axle sleeve B19 by manual wrench 20 and rotate.
Not sideslip is adjusted to substantially with the belt of vacuum filter in the position by manual wrench 20 regulating shaft bearing A at first.The position of travel switch A14, travel switch B15, travel switch C16 and travel switch D17 is set then.The installation site of travel switch A14 and travel switch B15 will guarantee that bearing block A1 can slide freely, is not stuck on guide rail.The installation site of travel switch C16 and travel switch D17 will guarantee that the vacuum filtration function is extracted into vacuum.
When vacuum filter belt deviation, belt is to travel switch C16 one side sideslip.Belt edge is met travel switch C16, travel switch C16 closure, and motor 13 main storys, motor 13 slows down through reductor 11, and speed reduces, and it is big that moment of torsion becomes.Reductor 11 passes to pinion 10 with kinetic energy, and pinion 10 passes to kinetic energy gear wheel 9 again, and through gear reduction, speed reduces once more, and it is big that moment of torsion becomes once more.Gear wheel 9 drives screw drive axle sleeve A8 and rotates, and screw drive axle sleeve A8 is pressed on the radial thrust bearing 7, and screw drive axle sleeve A8 drives bearing inner ring and rotates, and by the effect of radial thrust bearing 7, rotary resistance reduces.Because trapezoidal screw 4 can not rotate, screw drive axle sleeve A8 rotates, so that trapezoidal screw 4 under the effect of screw drive axle sleeve A8, is drawn forward is moving, trapezoidal screw 4 also is drawn forward moving, and trapezoidal screw 4 drives bearing block A1 again and moves forward.When the position that moves to setting, bearing block A1 touches travel switch A14, and motor 13 power supplys are disconnected, and motor 13 stops operating.Become big near the belt tension of travel switch C16 one side, belt is to travel switch D17 one side sideslip slowly.
When vacuum filter belt deviation, belt is to travel switch D17 one side sideslip.Belt edge is met travel switch D17, travel switch D17 closure, and motor 13 anti-pass, motor 13 slows down through reductor 11, and speed reduces, and it is big that moment of torsion becomes.Reductor 11 passes to pinion 10 with kinetic energy, and pinion 10 passes to kinetic energy gear wheel 9 again, and through gear reduction, speed reduces once more, and it is big that moment of torsion becomes once more.Gear wheel 9 drives screw drive axle sleeve A8 and rotates, and screw drive axle sleeve A8 is pressed on the radial thrust bearing 7, and screw drive axle sleeve A8 drives bearing inner ring and rotates, and by the effect of radial thrust bearing 7, rotary resistance reduces.Because the vacuum filter belt is tensioned, so bearing block A1 is subjected to all the time along the pulling force of belt shrinkage direction.Because bearing block A1 is subjected to all the time along the pulling force of belt shrinkage direction, trapezoidal screw 4 can not rotate, screw drive axle sleeve A8 backward rotation, so trapezoidal screw 4 moves backward, bearing block A1 also moves backward.When the position that moves to setting, bearing block A1 touches travel switch B15, and motor 13 power supplys are disconnected, and motor 13 stops operating.Diminish near the belt tension of travel switch C16 one side, belt is to travel switch C16 one side sideslip slowly.
The belt of vacuum filter just can only move in the scope of setting, and promptly moves back and forth between travel switch C16 and travel switch D17.The belt of vacuum filter moves back and forth between travel switch C16 and travel switch D17, just satisfies the service requirement of vacuum filter, guarantees that vacuum filter normally vacuumizes, thereby can guarantee well that vacuum filter normally moves.
The utility model vacuum filter automatic deviation-correcting device for belt, not only simple and reliable for structure, and do not need manually-operated, the automatic controlling level height can be realized the real-time automatic deviation correction of vacuum filter belt, guarantees that vacuum filter normally moves.
