Abstract

The utility model provides a former coal bunker center batcher, there is the barrel -type casing, the lower extreme of casing has circular bottom plate, there is circular feed opening the centre of bottom plate, the inner cone of axis on same straight line that has axis and casing in the casing, even there is the support arm between the inner wall of inner cone and casing, there is the blanking clearance between the lower extreme of inner cone and the bottom plate of casing, there is the roating seat centre of bottom plate, there is the radial unloading arm of the different curved in a ghent on the roating seat, the outer end and the shells inner wall of unloading arm offset, there is wear resistant material layer the outer end top of unloading arm, it has the unloading arm spacing ring along the circumference to have in the casing, the wear resistant material layer of the outer end top of unloading arm supports the below at the unloading arm spacing ring. The utility model discloses there is wear resistant material layer the outer end of unloading arm top, has in the casing along the circumference and has the unloading arm spacing ring, and the unloading arm is equivalent to the simple beam structure, when the unloading arm changes at circular bottom plate top spin, can not take place the unloading arm warping phenomenon that makes progress, can guarantee to let material follow bottom plate the circular feed opening in centre lastingly, discharge uniformly.

Description

A kind of run coal bin center feeder
Technical field
This utility model is related to a kind of boiler of power plant run coal bin central coal feeder, in particularly a kind of boiler of power plant run coal bin The unloading arm of heart feeder.
Background technology
Heat power plant boiler coal supply system has vertical coal storehouse, and raw coal needed for boiler combustion is fine grained loose unpacked material. Feeder is arranged at the bottom in vertical coal storehouse.Feeder is used for the requirement for pressing boiler equably to boiler coal supply.Feeder has and shakes Dynamic feeder, disk feeder, reciprocating coal feeder, center feeder etc., wherein center feeder are that raw coal can be obtained First in first out, persistently, the preferable feeder that is evenly supplied.
Center feeder has barrel-type casing, and there are circular feed opening, housing in the centre that there is circular bottom plate, base plate the lower end of housing Inside there is the axis of axis and housing inner cone on the same line, between inner cone and the inwall of housing, be connected with support arm, it is interior There is rotating seat the centre for having blanking clearance, base plate between the lower end of cone and the base plate of housing, has a Gent very bent on rotating seat Linear radial direction unloading arm, outer end and the inner walls of unloading arm offset.
Center feeder is arranged on vertical coal storehouse bottom, between the barrel-type casing and inner cone of raw coal Jing center feeders Annular gap fall on base plate.
During use, the rotating seat rotation of center feeder is driven with driving means, drive unloading arm is on circular bottom plate Rotation, unloading arm stir the material of substrate to central motion, and circle feed opening is discharged from the middle of base plate.Unloading arm Outer end is offseted with inner walls, can prevent material from adhering in inner walls during rotation.
The unloading arm of this center feeder is cantilever beam structure, and the inner of unloading arm is integrally fixed on rotating seat, discharging The outer end of arm does not constrain, and when in use, because the outer end of unloading arm does not constrain, unloading arm occurs because material stops sometimes The upturned phenomenon in outer end, after the outer end of unloading arm is upturned, it is impossible to effectively stir the material of substrate constantly To central motion, it is impossible to allow material circle feed opening from the middle of base plate persistently, equably to discharge.
The content of the invention
The purpose of this utility model is, in order to overcome above-mentioned deficiency, to propose that a kind of outer end that can prevent unloading arm is upturned Run coal bin center feeder.
This utility model is realized with the following method.
Run coal bin center feeder has barrel-type casing, and there is circular blanking the centre that there is circular bottom plate, base plate the lower end of housing Mouthful, there is the axis of axis and housing inner cone on the same line in housing, be connected between inner cone and the inwall of housing Brace, the centre for having blanking clearance, base plate between the lower end of inner cone and the base plate of housing have rotating seat, have one on rotating seat The radial direction unloading arm of particular curve shape, outer end and the inner walls of unloading arm offset, and have high-abrasive material above the outer end of unloading arm Layer, having in housing circumferentially has unloading arm spacing ring, and the wear-resistant material layer above the outer end of unloading arm is against unloading arm spacing ring Lower section.
This utility model in use, because there is wear-resistant material layer above the outer end of unloading arm, has in housing along circle There is unloading arm spacing ring week, the wear-resistant material layer above the outer end of unloading arm is against the lower section of unloading arm spacing ring, and unloading arm exists When rotating above circular bottom plate, the outer end of unloading arm has constraint equivalent to simple beam structure, and the outer end of unloading arm will not occur Upturned phenomenon, can guarantee that and allow material circle feed opening from the middle of base plate persistently, equably to discharge.
Below in conjunction with the accompanying drawings, the utility model is further described.
Description of the drawings
Fig. 1 is that signal is cutd open by a kind of main view office of the run coal bin center feeder proposed according to scheme of the invention of the present utility model Figure;
Fig. 2 is enlarged diagram at the I of Fig. 1;
Fig. 3 is the A-A generalized sections of Fig. 1.
Specific embodiment
In Fig. 1, Fig. 2, there is circular bottom plate 2 lower end that run coal bin center feeder has barrel-type casing 1, housing, in base plate Between have circular feed opening 3, have the axis of axis and housing inner cone 4 on the same line, inner cone and housing in housing Support arm 5 is connected between inwall, there is rotation the centre for having blanking clearance h, base plate between the lower end of inner cone and the base plate of housing Seat 6, has the different curved radial direction unloading arm 7 of a Gent on rotating seat, outer end and the inner walls of unloading arm offset, unloading arm There is wear-resistant material layer 8 above outer end, having in housing, wear-resisting above the outer end of unloading arm Material layer is against the lower section of unloading arm spacing ring.

Claims (1)

1. a kind of run coal bin center feeder, has barrel-type casing, and the centre that there is circular bottom plate, base plate the lower end of housing has under circle Material mouth, has the axis of axis and housing inner cone on the same line, is connected between inner cone and the inwall of housing in housing Support arm, the centre for having blanking clearance, base plate between the lower end of inner cone and the base plate of housing have rotating seat, have one on rotating seat The different curved radial direction unloading arm of Gent, outer end and the inner walls of unloading arm offset, it is characterised in that:
