Abstract
The utility model provides a traveling grate boiler flue gas turns to room with grey device that falls, it relates to the grey device that falls, concretely relates to traveling grate boiler flue gas turns to room with grey device that falls. The utility model discloses an it turns to indoor deposition caused the influence to boiler efficiency problem to solve the traveling grate boiler flue gas. The utility model discloses a pull rod, wall bushing and the ash door of falling, flue gas turn to behind the room water -cooling wall and are close to the flue gas and turn to behind the room one end of package wall and open and have the through -hole, and the through -hole lies in the fall top of cinder notch of boiler, and the ash door that falls sets up in rear through -hole's upper end, and the wall bushing cartridge turns to room hou bao on the wall at the flue gas, and the one end of pull rod is passed the wall bushing and is leaked outward, and the other end of pull rod is connected with the ash that falls. The utility model is used for the boiler field.
Description
Technical field
The utility model relates to a kind of ash dropped unit, is specifically related to a kind of chain grate boiler gas reversal chamber ash dropped unit, belongs 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.
Utility model content
The utility model is solve 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 utility model is the technical scheme taked that solves the problem: the utility model comprises 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 utility model comprises 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 beneficial effects of the utility model are: 1, the utility model 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 utility model adopts drawer-type structure, succinctly easy to operate; 3, pull bar of the present utility model extends to outside flue, can be cleaned out by the dust stratification in gas reversal chamber when boiler not blowing out.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
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.
