Abstract

The invention relates to an ash dropping device, in particular to an ash dropping device for a flue gas reversing chamber of a chain-grate boiler, and aims to solve the problem that the heat efficiency of the boiler is affected by accumulated ash in the flue gas reversing chamber of the chain-grate boiler. The ash dropping device comprises pull rods, a wall bushing and ash dropping doors, wherein through holes are formed in one end, close to a rear surrounding wall of the flue gas reversing chamber, of a rear water cooling wall of the flue gas reversing chamber and located above a slag dropping port of the boiler, the ash dropping doors are arranged at upper ends of rear through holes, the wall bushing is mounted on the rear surrounding wall of the flue gas reversing chamber in an inserted manner, one end of each pull rod penetrates through the wall bushing to be exposed, and the other end of each pull rod is connected with the corresponding ash dropping door. The ash dropping device is applied to the boiler field.

Description

A kind of chain grate boiler gas reversal chamber ash dropped unit
Technical field
The present invention relates to a kind of ash dropped unit, be specifically related to a kind of chain grate boiler gas reversal chamber ash dropped unit, belong to field of boilers.
Background technology
When coal-burning boiler runs, some imperfect combustion solid granule and ashes in the heat smoke formed after coal combustion, can be carried.Due to chain grate boiler structural factor, flue gas is caused easily to form a dust stratification region at the rear water-cooling wall surface bottom in reversal chamber region.When boiler operation time is shorter, granule and ashes are little on boiler operatiopn impact, but if things go on like this dust stratification is crossed and impacted boiler thermal output at most, can result in blockage time serious to flue.Therefore must clear up by the dust stratification of regularly blowing out to this region.
Summary of the invention
The present invention solves the problem that in traveling-grate stoker boiler smoke reversal chamber, dust stratification impacts boiler thermal output, and then proposes a kind of chain grate boiler gas reversal chamber ash dropped unit.
The present invention is the technical scheme taked that solves the problem: the present invention includes pull bar, wall bushing and ash-dropping door, after gas reversal chamber, one end of water-cooling wall bag wall after gas reversal chamber has through hole, and through hole is positioned at boiler falls the top of cinder notch, ash-dropping door is arranged on the upper end of rear through hole, wall bushing to be inserted into after gas reversal chamber on bag wall, one end of pull bar leaks outside through wall bushing, and the other end of pull bar is connected with ash-dropping door.
The present invention includes pull bar, wall bushing and multiple ash-dropping door, after gas reversal chamber, water-cooling wall has multiple through hole successively, the upper end of each through hole is respectively equipped with an ash-dropping door, wall bushing to be inserted into after gas reversal chamber on bag wall, one end of pull bar leaks outside through wall bushing, and multiple ash-dropping door is all connected with the other end of pull bar.
The invention has the beneficial effects as follows: 1, the present invention offers through hole by lowest part in gas reversal chamber, and a rod-pulling type ash-dropping door is set, pull bar is pulled to open ash-dropping door, the dust stratification in gas reversal chamber is made to fall in cinder notch, finally discharge with slag, effectively solve the dust stratification problem in gas reversal chamber, avoid the impact that in gas reversal chamber, dust stratification causes boiler thermal output; 2, the present invention adopts drawer-type structure, succinctly easy to operate; 3, pull bar of the present invention extends to outside flue, can be cleaned out by the dust stratification in gas reversal chamber when boiler not blowing out.

Fig. 1 is overall structure schematic diagram of the present invention.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 illustrates present embodiment, described in present embodiment, a kind of chain grate boiler gas reversal chamber ash dropped unit comprises pull bar 1, wall bushing 2 and ash-dropping door 4, after gas reversal chamber, one end of water-cooling wall 5 bag wall 6 after gas reversal chamber has through hole 7, and through hole 7 is positioned at boiler falls the top of cinder notch 3, ash-dropping door 4 is arranged on the upper end of rear through hole 7, wall bushing 2 to be inserted into after gas reversal chamber on bag wall 6, one end of pull bar 1 leaks outside through wall bushing 2, and the other end of pull bar 1 is connected with ash-dropping door 4.
When boiler flue is wider, after gas reversal chamber, water-cooling wall 5 can be offered side by side multiple through hole 7, each through hole 7 is arranged respectively an ash-dropping door 4, each ash-dropping door 4 is connected with one end of a pull bar 1 respectively, the other end of each pull bar 1 all leaks outside through bag wall 6 after gas reversal chamber, so arranges, and can carry out local cleaning to flue, ash-dropping door 4 that will be not all is opened, and avoids gas reversal chamber to leak out and flue gas heat loss.
Detailed description of the invention two: composition graphs 1 illustrates present embodiment, described in present embodiment, a kind of chain grate boiler gas reversal chamber ash dropped unit comprises pull bar 1, wall bushing 2 and multiple ash-dropping door 4, water-cooling wall 5 has successively multiple through hole 3 after gas reversal chamber, the upper end of each through hole 3 is respectively equipped with an ash-dropping door 4, wall bushing 2 to be inserted into after gas reversal chamber on bag wall 6, one end of pull bar 1 leaks outside through wall bushing 2, and multiple ash-dropping door 4 is all connected with the other end of pull bar 1.
