Abstract

Boiler slag storehouse row slag door structure. Because the pneumatic picture peg door needs to bear certain pressure, this makes the frictional force between picture peg door bottom gyro wheel and the picture peg door increase, simultaneously along with the frequent switching action of the pneumatic picture peg door in slag storehouse, the gyro wheel diminishes because of wearing and tearing very easily, can't play the effect of supporting the picture peg. The utility model discloses the constitution includes: the air cylinder comprises a frame (3), an air cylinder (1) and an inserting plate (2), wherein the upper end and the lower end of each of two sides in the frame are respectively fixed with a sliding rail (7), the inserting plate is inserted into the frame, air cavities (6) are respectively formed in the two sides of the inserting plate, opposite to the sliding rails on the corresponding sides, and the end parts of the air cavities are communicated with an air pipe (5); and the push rod of the air cylinder is fixed with the inserting plate through a bolt. The utility model is used for boiler slag bin slag discharging door.

Description

Slag discharging door structure of boiler slag bin

The technical field is as follows:

the utility model relates to a slag discharge door structure of a boiler slag bin.

The background art comprises the following steps:

during the operation of the dry-type slag extractor, ash and slag are conveyed to the interior of the slag bin through the conveying belt to be temporarily stored, the pneumatic inserting plate door is horizontally arranged at the bottom of the slag bin, the pneumatic inserting plate door is generally in a closed state, the ash and slag are accumulated on the upper part of the inserting plate door, and the pneumatic inserting plate door is opened to discharge the ash and slag when the ash and slag are cleared.

Because the pneumatic picture peg door needs to bear certain pressure, this makes the frictional force between picture peg door bottom gyro wheel and the picture peg door increase, simultaneously along with the frequent switching action of the pneumatic picture peg door in slag storehouse, the gyro wheel diminishes because of wearing and tearing very easily, can't play the effect of supporting the picture peg.

The utility model has the following contents:

the utility model aims at providing a boiler slag bin slag discharging door structure.

The above purpose is realized by the following technical scheme:

a boiler slag bin slag discharge door structure comprises a frame, an air cylinder and an inserting plate, wherein the upper end and the lower end of two sides in the frame are respectively fixed with a sliding rail, the inserting plate is inserted into the frame, air cavities are respectively formed in the two sides of the inserting plate opposite to the sliding rails on the corresponding sides, and the end parts of the air cavities are communicated with an air pipe;

and the push rod of the air cylinder is fixed with the inserting plate through a bolt.

The boiler slag bin slag discharge door structure is characterized in that a gap is formed between the end part of the sliding track and the side surface of the frame.

The boiler slag bin slag discharge door structure is characterized in that the air outlet end of the air cavity is conical.

Has the advantages that:

1. the utility model discloses the picture peg adopts the orbital mode of sliding to slide, and increase support area and holding power prevent that picture peg door-trip in-process from taking place the skew, and the orbital structure of double track about the slip track adopts can reduce the lime-ash to a certain extent and drop to the lower part track on, reduces the orbital wearing and tearing in lower part, extension track life.

2. The utility model discloses an offer the air cavity on the picture peg, let in compressed air in to the air cavity through the trachea for compressed air blows off the lime-ash on the slip track and blows off, prevents that the picture peg from in the motion and mix with the lime-ash between the slip track and lead to wearing and tearing, influences its switch, has the clearance between orbital tip of sliding and the frame simultaneously, can guarantee like this that the part lime-ash on the slip track drops it is whole along with the promotion of picture peg.

Description of the drawings:

FIG. 1 is a front view of the present invention;

fig. 2 is a bottom view of the present invention;

FIG. 3 is a schematic view of the internal structure of the present invention;

FIG. 4 is a schematic structural view of the board;

in the figure: 1. a cylinder; 2. inserting plates; 3. a frame; 4. a boiler slag bin; 5. an air tube; 6. an air cavity; 7. a sliding track; 8. a gap.

The specific implementation mode is as follows:

example 1:

the utility model provides a boiler slag bin arranges slag door structure, its constitution includes frame 3, cylinder 1 and picture peg 2, the frame in the upper and lower both ends of both sides be fixed with slip track 7 respectively, the picture peg insert the frame in, the structure of double track way about the slip track adoption can reduce the lime-ash to a certain extent and drop to the lower part track on, reduce the orbital wearing and tearing of lower part, extension track life, the both sides of picture peg in with the slip track punishment relatively of corresponding side do not seted up air cavity 6, the tip and the trachea 5 intercommunication of air cavity, trachea in-connection compressed air, compressed air passes through the trachea and enters into the air cavity, discharges through the air cavity and blows off some lime-ash that falls on the slip track.

Example 2:

in order to enable ash on the sliding rail to be blown and the inserting plate to act together, a gap 8 is formed between the end part of the sliding rail and the side surface of the frame, so that the ash is blown by compressed air when the inserting plate slides, most of the ash drops after being blown, and a small amount of the ash is pushed along with the pushing of the inserting plate so as to drop through the gap after being pushed to the end part of the sliding rail.

Example 3:

in order to enable the air blown out after the air cavity is exhausted to be smoothly blown to the sliding rail, the air outlet end of the air cavity is conical.

Claims

1.
