Abstract
The utility model provides a suspension type centrifuge belt tensioning controlling means that does all can, the device utilize can be on the separating centrifuge fuselage horizontal slip's motor support and the resilience force behind the spring compression, realize the automatic tensioning of belt at the separating centrifuge working process, effectively prevent because belt lax and the phenomenon of skidding of production, the device can be through the instruction screw position who shows spring compression amount, and the size of accurate adjustment belt tensioning power still has limit function simultaneously, can restrict the radially volume of rocking the displacement of rotary drum top belt pulley, improves the operation stability of separating centrifuge.
Description
Technical field
This utility model belongs to centrifugation machinery technical field, is specifically related to a kind of suspension centrifugal separator belt tension force control device.
Background technology
Centrifugal separator utilizes the various compositions in the centrifugal force separate liquefied mixture that rotary drum high speed rotating produces, it it is widely used separation machinery, suspension centrifugal separator is one of which version, its rotary drum suspended fixing is in seperator frame, the belt transmission utilizing top is driven drum rotating by motor, operating is stablized, and working service is convenient.
Suspension centrifugal separator driving belt in use can produce to relax, and belt with reduced tensioning force causes that the frictional force between belt and belt wheel reduces, skidding even occurs.It is thus desirable to keep its transmission capacity by the method for tightening belt.All adopting the method adjusting centre-to-centre spacing to carry out tightening belt in existing suspension centrifugal separator, belt tension size controls inaccurate, and operating process is complicated；It is periodically subject to owing to adjusting, therefore can not keep stablizing of belt tension, adjustment process simultaneously also needs to shut down, seperator can be produced and bring adverse effect.
It addition, in the suspension centrifugal separator of prior art, rotary drum takes resiliency supported to be fixed in seperator frame, and the natural frequency of vibration of such rotor system is little, run up and be not easy to produce resonance, there is good center of gravity self-aligning ability simultaneously.But it is less in support stiffness by it, rotary drum high speed rotating in seperator work process, when the outer fluctuation such as belt tension or solid bowl centrifuges power occurs, belt pulley above rotary drum easily produces radially to rock, when radial displacement cross conference also time cause belt tension fluctuation, rotary drum operating instability, affects equipment safety operation.
Summary of the invention
This utility model is for problems of the prior art, a kind of suspension centrifugal separator belt tension force control device is provided, can the size of belt tension processed in seperator work process, automatically the tensile force of belt is adjusted, effectively prevent owing to lax generation of belt is skidded, also there is the radial direction of belt pulley above restriction rotary drum simultaneously and rock the function of displacement, improve seperator run stability.
The technical scheme is that seperator of this utility model drives motor to be fixed on the electric machine support with front wheel and rear roller of the side, and roller is positioned at the chute in seperator frame, and support of motor can thus move forward and backward；Columnar spring base is fixed in the middle part of support of motor, built-in spring, and tensioning screw is positioned at spring rear, and its axis overlaps with the centrage of spring；Spring pressuring ring holddown spring end face is passed through in one end of tensioning screw, the other end is fixed on the spiro rod support of seperator upper rack by nut, by adjusting the axial location of tensioning screw, it is possible to make spring be compressed, support of motor is produced outside thrust by the resilience force of spring, thus tightening belt.Spring base front end has a cannelure, and cannelure has scale, and instruction screw is arranged in groove, and its tail end is fixed on spring pressuring ring, by indicate screw position can the decrement of Accurate Determining spring, thus controlling the size of the tensile force of belt.After suspension centrifugal separator adopts said structure, in work process when belt generation relaxation, spring can extend automatically, electric machine support is made to be moved rearwards by, increase the centre-to-centre spacing of two belt pulleys, make the tensioning degree that belt maintenance is enough, it is to avoid produce skidding.
In the technical scheme that this utility model adopts, tapped spacing ring is arranged in the middle part of tensioning screw, it is positioned at outside spring base, and is adjusted by nut and lock its axial location on tensioning screw, make to keep between spring base and spacing ring suitable axial gap.When the belt pulley above rotary drum occurs radially to rock, the change in this gap can be caused, when belt pulley towards motor direction displacement excessive time, spacing ring will contact with spring base, make spring ineffective, pulley center is made not change with load, thus the radial direction limiting belt pulley rocks displacement, it is ensured that seperator safe operation.
Compared with prior art, this utility model can adjust the size of suspension centrifugal separator belt tension automatically, effectively prevent from work process occurs belt creep phenomenon, there is belt pulley above restriction rotary drum simultaneously and radially rock the function of displacement, be effectively improved the run stability of seperator.

Detailed description of the invention
Below in conjunction with accompanying drawing 2 embodiment, this utility model detailed description of the invention is described in detail.
The frame of suspension centrifugal separator is made up of column 16 and crossbeam 14, and crossbeam both sides have the chute of level, and the front wheel 13 and the rear roller 9 that are fixed on both sides on support of motor 7 are placed in chute, makes the support of motor can slide anteroposterior.Motor 20 is bolted on support of motor, and motor pulley 19 is fixed in the rotating shaft of motor by shaft coupling 18.Spring base 1 is welded on above support of motor, and spring 2 is placed in spring base.Tensioning screw 6 is positioned at spring rear, and its axis overlaps with the centrage of spring, and spring pressuring ring 3 holddown spring end face is passed through in one end of tensioning screw, and the other end is fixed on the spiro rod support above crossbeam 8 by nut.By adjusting the axial location of tensioning screw, it is possible to make spring be compressed, and support of motor being produced outside thrust, thus tightening belt, for ease of adjusting operation, the tail end of tensioning screw is processed to square.Spring base front end has a cannelure, instruction screw 4 is arranged in groove, and its tail end is threadedly secured on spring pressuring ring, when spring is compacted, instruction screw position in groove can produce change, thus the tensile force size of the decrement of control spring and belt.
Tapped spacing ring 5 is arranged on tensioning screw, is positioned at outside spring base, and is adjusted by nut and lock its axial location on tensioning screw, makes to keep between spring base and spacing ring suitable axial gap.When the belt pulley above separator drum occurs radially to rock due to reasons such as load fluctuations, the change in this gap can be caused, when belt pulley towards motor direction displacement excessive time, this gap is zero, spacing ring directly will contact with spring base, make that spring is ineffective no longer to be compressed, and make pulley center no longer change with the fluctuation of radial load, thus limiting the radial direction of belt pulley above rotary drum to rock displacement, it is ensured that seperator safe operation.
