Abstract
The invention discloses a kind of novel spiral classifier lower support device, comprise spindle nose, lower support pedestal, the vestibule on described lower support pedestal is square, and described spindle nose has installed axle sleeve, and axle sleeve and spindle nose are by fixture and together with being bolted to.Device of the present invention can avoid the mutual wearing and tearing of grader bottom spindle nose and lower support seat effectively, greatly reduces the generation of fault, and it is convenient that axle sleeve and wear resistant filler are changed, and can greatly reduce the spiral classifier downtime, reduce maintenance cost.
Description
Technical field
The present invention relates to a kind of spiral classifier, particularly a kind of spiral classifier bottom bracing structure.
Background technology
Spiral classifier is one of common equipment of the industries such as metallurgy, mine, and its proportion by solid particle is different, and the principle that the speed precipitated in a liquid is different, carries out a kind of equipment of mechanical classification.Due to the condition of work of spiral classifier and the restriction of structure, its underpart bracing or strutting arrangement is immersed in ore pulp for a long time and works, and traditional lower seat comprises pedestal, pedestal offers circular screwhole, bearing is had in screw, the connecting axle of spiral classifier hollow shaft end assigned by bearing, connecting axle rotates relative to screw, and the surfaces of revolution directly contacts with ore pulp, therefore ore pulp easily penetrates into screw from gap, bearing and axle is caused very easily to wear and tear, give design, operation and maintenance causes inconvenience, during grader is run, fault rate is high, keep in repair frequent and consuming time, great impact is caused to production.In order to reduce wearing and tearing, publication number is the lower seat that the Chinese patent of CN202733344U discloses a kind of spiral classifier, compression screw offered by this bearing on bearing body, screw internal fixtion has the rubber axle sleeve matched with the connecting axle of spiral classifier hollow shaft end, the Bearning mechanism in compression screw is instead of by rubber axle sleeve, ore pulp can be effectively avoided to enter in compression screw, also can produce friction with rubber axis inner room after but the connecting axle of hollow shaft end does long-time rotary motion, the damage of connecting axle and bearing can be caused equally.
Summary of the invention
The object of the present invention is to provide a kind of novel spiral classifier lower support device; this device is by axle sleeve and fill wear resistant filler protection; effectively can avoid the mutual wearing and tearing of grader bottom spindle nose and lower support seat; greatly reduce the generation of fault; it is convenient that axle sleeve and wear resistant filler are changed, and can greatly reduce the spiral classifier downtime, reduce maintenance cost.
For achieving the above object, the present invention realizes by the following technical solutions: a kind of novel spiral classifier lower support device, comprise spindle nose, lower support pedestal, it is characterized in that, vestibule on described lower support pedestal is square, described spindle nose has installed axle sleeve, and axle sleeve and spindle nose are by axle sleeve fixture and together with being bolted to.
Further, the vestibule on described lower support pedestal and axle sleeve is installed spindle nose between be filled with wear resistant filler.
Further, the wear resistant filler in described supporting seat body opening chamber is being fixed by porose gland and bolt close to spindle nose one end, is then fixed by blind hole gland and bolt in addition away from one end of spindle nose.
Further; described porose gland is provided with the hole for installing spindle nose and sleeve assembly; its shape is oval; can farthest avoid axle sleeve with spindle nose in running with the mutual wearing and tearing of porose gland, both can protect the damage of porose gland two service life extending axle sleeve.
Beneficial effect of the present invention: spiral classifier lower support device of the present invention adds the axle sleeve fixing with spindle nose, the damage that spindle nose causes because of friction can be greatly reduced, vestibule on lower support pedestal and axle sleeve is installed spindle nose between be filled with wear resistant filler, avoid the friction between spindle nose and base and greatly reduce the loss of equipment, this device structure is simple, it is convenient that axle sleeve and wear resistant filler are changed, therefore easy to maintenance, fast, the spiral classifier downtime can be greatly reduced, reduce maintenance cost, fast recovery equipment runs, reduce equipment to greatest extent because fault is on producing the impact caused.
Accompanying drawing explanation
Fig. 1 is the generalized section of spiral classifier lower support device of the present invention;
Fig. 2 is A-A portion cross-sectional schematic in Fig. 1;
In figure: 1, spindle nose, 2, axle sleeve, 3, bolt, 4, porose gland, 5, lower support pedestal, 6, wear resistant filler, 7, axle sleeve fixture, 8, blind hole gland, 9, bolt, 10, bolt.
Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with accompanying drawing:
A novel spiral classifier lower support device, comprises spindle nose 1, lower support pedestal 5, and the vestibule on described lower support pedestal is square, and described spindle nose 1 has installed axle sleeve 2, and axle sleeve 2 and spindle nose 1 are fixed together by axle sleeve fixture 7 and bolt 9.
As shown in the figure, bottom spindle nose 1 installs an axle sleeve 2 additional, and spindle nose 1 and axle sleeve 2 are fixed by axle sleeve fixture 7 and bolt 9 with axle sleeve 2 by spindle nose 1, the relative radial direction of restriction spindle nose 1 and axle sleeve 2 and axially-movable; The vestibule of lower support pedestal 5 and axle sleeve 2 is installed spindle nose 1 between be filled with wear resistant filler 6, bottom spindle nose 1 rotates relative to vestibule in wear resistant filler 6; Porose gland 4 is fixed on lower support seat 5 with blind hole gland 8 by the bolt 3 of porose gland and the bolt 10 of blind hole gland, to limit the axially-movable of wear resistant filler 6 in lower support seat 5, fixed by porose gland 4 and bolt 3 close to spindle nose one end, the one end in addition away from spindle nose is then fixed by blind hole gland 8 and bolt 10; Described porose gland 4 have for the hole of installation shaft 1 with the assembly of axle sleeve 2; its shape is oval; can farthest avoid axle sleeve with spindle nose in running with the mutual wearing and tearing of porose gland, both can protect the damage of porose gland two service life extending axle sleeve.
By above-mentioned embodiment, thus complete the bottom spindle nose of spiral classifier lower device and running without wearing and tearing of lower support seat.
