Abstract

The utility model discloses a raw coal bunker loosening and dredging device. The raw coal bunker loosening and dredging device comprises a raw coal bunker, a rotary loosening rod, a loosening rod connector, a steering coupler, a speed reducer, a seal device and an electric cabinet. The raw coal bunker loosening and dredging device loosens materials through the multi-azimuth combined rotary-cut movement of a scrapper which is arranged on the rotary loosening rod, avoids the phenomenon of coal blocking and arch-forming, enables raw coal in the raw coal bunker to keep a flowing state, throughout solves the blocking problem of the raw coal bunker, is low in cost, simple in structure, is convenient to install, wide in dredging range, and strong in practical utility, is mainly applied in anti-blocking of a boiler raw coal bunker of a thermal power plant and is suitable for various coal quality such as coal slime, blown coal and frozen coal.

Description

The run coal bin dredger that loosens
Technical field
The utility model relates to a kind of loose dredger, is specifically related to the loose dredger of a kind of run coal bin.
Background technology
It is the hard nut to crack of thermal powerplant that run coal bin stops up, generally occur in run coal bin bottom conical section, in order to address this problem, mainly be to adopt rotary coal scuttle dredging device to be installed or run coal bin is carried out structural transformation at present, but this kind equipment cost is high, huge structure, install complicated and when using the extremely strong coal of the agglomeration such as coal slime the dredging effect undesirable.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art provide a kind of cost low, simple in structure, anti-blocking loose effective, be applicable to coal slime, brown coal, freeze the loose dredger of run coal bin of the various atures of coal such as coal.
For achieving the above object, the technical solution of the utility model is:
A kind of run coal bin dredger that loosens comprises run coal bin, electric cabinet, characterized by further comprising the loose bar of rotation, loose rod connector, turns to coupler, reductor and sealing arrangement; The loose bar of described rotation is 3, is installed in the run coal bin, and is combined into taper, and the top interface point is connected by loose rod connector, and the bottom is by turning to coupler to be connected with the output shaft of reductor; Described reductor is 3, and reductor is captiveed joint with the outer wall of run coal bin by the flange seat of output flange, and is evenly arranged by 120 degree; Described run coal bin 1 position of opening of coupler and speed reducer output shaft junction that turns to is equipped with sealing arrangement; Described reductor is controlled by electric cabinet.
On the loose bar of described rotation the scraper that some layers of length differ is installed.
The utility model is installed in run coal bin bottom conical section, by such scheme as can be known, the utlity model has following beneficial effect: 1, by rotating the rotary-cut campaign of loose bar upper blade, bulk material, prevent canopy coal, knot arch, 3 bar aggregate motions make raw coal keep flow regime in run coal bin simultaneously, and enlarged loose scope, thereby effectively solve the run coal bin blockage problem.2, low, simple in structure, easy for installation, the dredging scope of cost is wide and practical, be mainly used in the block clearing of heat power plant boiler raw coal bin anti-blocking, be applicable to coal slime, brown coal, freeze the various atures of coal such as coal, also can be applicable to the anti-blocking of other industry feed bins such as iron and steel, chemical industry.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure, 1. run coal bin 2. rotates loose bar, and 3. loose rod connector 4. turns to coupler, 5. reductor, 6. output shaft, 7. output flange, 8. flange seat, 9. sealing arrangement, 10. scraper, 11. electric cabinet, 12. interface points, 13. position of opening, 14. outer walls, 15. access opening.
The specific embodiment
Such as Fig. 1, shown in 2, the utility model comprises run coal bin 1, the loose bar 2 of rotation, loose rod connector 3, turns to coupler 4, reductor 5, sealing arrangement 9 and electric cabinet 11.
The loose bar 2 of rotation is 3, and length is consistent, is installed in the run coal bin 1, and be combined into taper, top interface point 12 is connected by loose rod connector 3, and the loose bar 2 of each rotation can be rotated freely, and the bottom is by turning to coupler 4 to be connected with the output shaft 6 of reductor 5; At the loose bar 2 of rotation the scraper 10 that some layers of length differ is installed, and when guaranteeing that the loose bar 2 of rotation rotatablely moves, the scraper 10 on the loose bar 2 of adjacent rotation does not interfere with each other; And scraper 10 cutter heads down, prevents from hanging foreign matter.
At run coal bin 1 position of opening 13 that turns to coupler 4 with output shaft 6 junctions of reductor 5 sealing arrangement 9 is installed, prevents that raw coal from leaking.
Reductor 5 is 3, and reductor 5 is captiveed joint with the outer wall 14 of run coal bin 1 by the flange seat 8 of output flange 7, and is evenly arranged by 120 degree; Reductor 5 is by electric cabinet 11 controls.
Outer wall 14 at run coal bin 1 has access opening 15, easy access.
The utility model drives scraper 10 by 3 loose bars 2 of rotation and carries out multi-faceted combination rotary-cut campaign, prevents canopy coal, knot arch, and bulk material, makes former coal particle in run coal bin 1 interior maintenance flow regime; Simultaneously, the up and down height of the loose bar 2 of rotation can design according to the run coal bin structure with the position, guarantees loose height and the effect of the loose bar 2 of rotation, thereby thoroughly solves run coal bin 1 chute blockage problem.

Claims (2)

1. the loose dredger of run coal bin comprises run coal bin, electric cabinet, it is characterized in that: also comprise the loose bar of rotation, loose rod connector, turn to coupler, reductor and sealing arrangement; The loose bar of described rotation is 3, is installed in the run coal bin, and is combined into taper, and the top interface point is connected by loose rod connector, and the bottom is by turning to coupler to be connected with the output shaft of reductor; Described reductor is 3, and reductor is captiveed joint with the outer wall of run coal bin by the flange seat of output flange, and is evenly arranged by 120 degree; The described run coal bin position of opening of coupler and speed reducer output shaft junction that turns to is equipped with sealing arrangement; Described reductor is controlled by electric cabinet.
