Description
Technical field:
The utility model relates to a kind of coal pulverizers to enter the wind dust-proof air door structure.
Background technique:
Be currently installed in thermal power plant coal pulverizer air duct air door only one, coal pulverizer air duct is that one kind is easy to accumulate
The environment of ash, equipment works herein for a long time will cause bite, hinder stroke or even deformation, and air door is difficult after similar situation occurs
The either full intake for influencing coal pulverizer that closes of standard-sized sheet is to limit its working efficiency and economic benefit.
Utility model content:
The purpose of this utility model is to solve existing air door and work herein for a long time to will cause bite, hinders stroke, even
The problem of deformation, provides a kind of dust-proof air door structure of coal pulverizer air inlet for avoiding air door stuck.
Above-mentioned purpose is realized by following technical scheme:
A kind of dust-proof air door structure of coal pulverizer air inlet, composition includes: air duct, and bracket, institute is arranged in the air duct top
The air duct lower part setting pedestal stated, the pedestal are fixedly connected with the bracket, and slideway, institute are fixed in the air duct
Sliding rail is provided in the slideway stated, the sliding rail lower part is fixedly connected with plate, and the bracket side passes through with master cylinder
Bolt is fixedly connected, and the other side and the countercylinder of the bracket are bolted to connection, the master cylinder and described
Plate is fixedly connected, and the countercylinder and the plate are hinged.
The coal pulverizer enters the wind dust-proof air door structure, and the countercylinder is horizontal by 30-45 °.
The utility model has the advantages that
1. board plug structure is arranged in the utility model, it can prevent air door inlet side from accumulating a large amount of dust, plate is pull
Form the case where can preventing the bite of plate and air door, hindering stroke or even deformation.
The utility model stops the First air that can completely cut off tunnel inlet when mill or coal-grinding machine overhauling completely, can reach and stop
Desired effect when mill or maintenance.
The utility model can reduce abrasion of the dust stratification to air door, can be improved the service life of air door, reduce maintenance at
This.

Specific embodiment:
Embodiment 1:
A kind of dust-proof air door structure of coal pulverizer air inlet, composition includes: air duct 4, and bracket 2 is arranged in the air duct top,
Pedestal 6 is arranged in the air duct lower part, and the pedestal is fixedly connected with the bracket, is fixed with slideway in the air duct
12, slideway and air duct inside are the form welded, and sliding rail 14, the sliding rail lower part and plate 3 are provided in the slideway
It is fixedly connected, by rotation axis connection, pulley is in contact with slideway top for sliding rail top and pulley 13, it is ensured that plate movement
It is smooth, plate and sliding rail are similarly the form of welding, and the bracket side is bolted to connection with master cylinder 5, institute
The other side for the bracket stated is bolted to connection with countercylinder 7, and the master cylinder is fixedly connected with the plate, institute
The countercylinder stated and the plate are hinged, and master cylinder is that plate is pushed to carry out pull movement, and countercylinder is taken out to plate
Locking after drawing in place；
Air door drive mechanism are as follows: air door is arranged inside air duct, fixing axle is interspersed in the middle part of air door, fixing axle end is under
Rocker arm 9 is fixedly connected, and lower shake-changing arm and connecting rod 10 are hinged, and connecting rod and upper rocker arm 11 are hinged, and upper rocker arm is fixedly connected with actuator 1,
Actuator controls upper rocker arm rotation, drives connecting rod to move up and down, realizes the rotation of lower shake-changing arm, so that air door carries out rotation realization and opens
It closes.
Embodiment 2:
Enter the wind dust-proof air door structure according to coal pulverizer described in embodiment 1, the countercylinder horizontal by 30-45 °,
Countercylinder is closed in plate has upward and forward motive force to plate afterwards in place, while guaranteeing that plate is closed in place, avoids flashboard
Stress overturning and it is stuck.
