Abstract
A supporting structure for vertical-disk filter main shaft, relates to the vertical-disk filter in a kind of aluminum oxide production process, particularly the improvement of filter main shaft supporting structure.It is characterized in that the axle head of vertical-disk filter main shaft adopts bearing shell to prop up structure; Its structure comprises bush seat, is arranged at the bearing shell between bush seat main shaft, coordinates, the locking nut be pressed abd fixed on by bearing shell on main shaft with main shaft threads.Eaves tile shoulder is respectively provided with in bearing shell both sides.The utility model can ensure bearing load carrying capacity, eliminates bearing frequent breakage phenomenon, thus increases the service life, reduce spare part expense simultaneously.
Description
Technical field
A supporting structure for vertical-disk filter main shaft, relates to the vertical-disk filter in a kind of aluminum oxide production process, particularly the improvement of filter main shaft supporting structure.
Background technique
In alumina producing, vertical-disk filter bears slurries to be separated conventional capital equipment, and the support end of vertical-disk filter main shaft adopts bearings.Because spring bearing will bear the deadweight of whole vertical plate and material weight, also bear distribution switchboard in end and inhale the axial force of blowing generation, in running, often occur the support end bearing damage on filter, damaged location is all bearing outer ring force part, and bearing outer ring crackle causes damage.Forint vertical-disk filter is obtained so that the France of the specification FD-37 F=152 ㎡ of import (four dishes) is high.Because bearing intensity is inadequate, under the responsive to axial force that distribution switchboard produces, cause bearing outer ring to rupture, frequent breakage, Inspection and maintenance difficulty is large, causes maintenance cost high, also have impact on equipment stable operation.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for above-mentioned prior art, provides one effectively can ensure bearing load carrying capacity, eliminates bearing frequent breakage phenomenon, increases the service life, reduce the supporting structure of the vertical-disk filter main shaft of maintenance and repair parts expense.
The purpose of this utility model is achieved through the following technical solutions.
A supporting structure for vertical-disk filter main shaft, is characterized in that the axle head of vertical-disk filter main shaft adopts bearing shell to prop up structure; Its structure comprises bush seat, is arranged at the bearing shell between bush seat main shaft, coordinates, the locking nut be pressed abd fixed on by bearing shell on main shaft with main shaft threads.
The supporting structure of a kind of vertical-disk filter main shaft of the present utility model, is characterized in that respectively being provided with bearing shell shoulder block in bearing shell both sides.
The supporting structure of a kind of vertical-disk filter main shaft of the present utility model, by carefully analyzing the Operation Conditions of existing equipment, precision mapping is carried out to the original size of equipment, meet install and use the prerequisite of condition under, bearing original structure is changed, transform bearing shell as to support, and the shaft shoulder of axial force is born in the design of bearing shell end, increase effectively radial direction, axial force that bearing shell bears, the bearing capacity of bearing is increased with this, eliminate bearing frequent breakage phenomenon, extend service life of equipment, effectively reduce spare part expense.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the supporting structure of a kind of vertical-disk filter main shaft of the present utility model;
Fig. 2 is the supporting structure signal of a kind of vertical-disk filter main shaft of prior art.
In figure, 6 is bearing, and 7 is bearing support.
Embodiment
As shown in Figure 1, a kind of supporting structure of vertical-disk filter main shaft, the axle head of its vertical-disk filter main shaft 1 adopts bearing shell to prop up structure; Its structure comprises bush seat 2, is arranged at the bearing shell 3 between bush seat main shaft, coordinates with main shaft threads, the locking nut 4 be pressed abd fixed on by bearing shell on main shaft, and is respectively provided with bearing shell shoulder block 5 in bearing shell both sides.
During operation, according to bearing support and major axis size design bearing shell, bush seat, bearing shell shoulder block, the locking nut of machine spindle, luggage of going forward side by side is joined; Bearing shell shoulder block is to the axially locating of back shaft, and bearing shell is to the radial location of back shaft, and bearing shell tip-clearance is designed to 2 millimeters, and after transformation, vertical plate support end exterior contour size and location dimension can remain unchanged, and can be that bearing shell supports by Reform of Bearing.By transformation roller bearings be bearing shell support, effectively ensure that bearing load carrying capacity, eliminate bearing frequent breakage phenomenon, thus increase the service life, reduce spare part expense simultaneously, eliminate the weak link of existing equipment.
Claims (2)
1. a supporting structure for vertical-disk filter main shaft, is characterized in that the axle head of vertical-disk filter main shaft adopts bearing shell to prop up structure; Its structure comprises bush seat, is arranged at the bearing shell between bush seat main shaft, coordinates, the locking nut be pressed abd fixed on by bearing shell on main shaft with main shaft threads.
2. the supporting structure of a kind of vertical-disk filter main shaft according to claim 1, is characterized in that respectively being provided with bearing shell shoulder block in bearing shell both sides.
