Technical field
The utility model relates to one kind suitable for reading to dragveyer can carry out closed detachable device, belong to dragveyer equipment
Technical field.
Background technique
Dragveyer is the Important Auxiliary equipment of Coal-fired group, and dragveyer will lead to unit and be forced to reduce once breaking down
Load, or even shut down.In unit operation, water is filled in dragveyer, water level will not cross the water sealing skirt 400mm of slag well, by water seal
The closing of skirt base opening in order to avoid air is leak into furnace from water sealing skirt base opening, and then maintains the negative pressure in burner hearth.And when dragveyer failure,
Dragveyer manhole door need to be opened on the spot to dragveyer slagging, and the water at the water sealing skirt base opening of slag well must be destroyed during slagging
Envelope, once combustion chamber draft will directly be destroyed by destroying water seal, causes unit steam temperature to be difficult to maintain, eventually leads to boiler extinguishment, machine
Group unplanned outage.Therefore, it is necessary to take technical measures, enable boiler in the continuous running of dragveyer maintenance period.
Utility model content
It is this technical problem to be solved by the utility model is to provide a kind of dragveyer locking device of fast demountable
Locking device can be quickly suitable for reading to dragveyer to carry out reliably before water seal at the water sealing skirt base opening that ring slag well is broken in dragveyer slagging
Closing avoids dragveyer from causing since slagging on the spot destroys water seal to maintain the negative pressure in boiler furnace in necessary range
Boiler extinguishment event.
The technical solution for solving above-mentioned technical problem is:
A kind of dragveyer locking device of fast demountable, it is made of track, cover board, seal closure, multiple groups track welding
The edge on dragveyer shell, multiple groups track is located between the water sealing skirt of adjacent slag well at neutral gear and the water sealing skirt of outer end slag well
At the neutral gear of dragveyer shell both ends, track is perpendicular to dragveyer length direction, and every group of track is by two parallel steel tubes or fashioned iron
Composition, cover board is rectangle steel plate, is laid with muti-piece cover board, cover board and track along the length direction sequence of track on every group of track
To be slidably matched, cover board is by the neutral gear and water sealing skirt of outer end slag well and dragveyer shell both ends between the water sealing skirt of adjacent slag well
It is covered at neutral gear, the gap welded seal cover between two side body of water sealing skirt and dragveyer of each slag well, seal closure will
Gap covering.
There are flanging vertically downward in the dragveyer locking device of above-mentioned fast demountable, the plate face two sides of the cover board, folding
Side is located at the outside of track, and the width of flanging is less than the height of track, and flanging inside is to be slidably matched with track lateral wall.
The dragveyer locking device of above-mentioned fast demountable, there is push-and-pull orifice plate in the plate face of the cover board, and push-and-pull orifice plate is
Rectangle steel plate, push-and-pull orifice plate are vertically welded in the plate face of cover board, and pushing and pulling in the plate face of orifice plate has push-and-pull hole.
The beneficial effects of the utility model are:
The utility model is along track is laid on dragveyer shell, and cover board can slide in orbit, the adjacent slag of quick closure
The water sealing skirt of neutral gear and outer end slag well and dragveyer shell both ends neutral gear between the water sealing skirt of well reach and close most of fishing slag
The purpose of machine；Seal closure can close the gap between two side body of water sealing skirt and dragveyer of each slag well, avoid air from
Gap between two side body of water sealing skirt and dragveyer is leak into burner hearth.
The utility model structure is simple and convenient to operate, and can realize the dragveyer major part suitable for reading before slagging with rapid-assembling/disassembling
Closing, to maintain the negative pressure in boiler furnace in necessary range, pot caused by avoiding due to dragveyer slagging destruction water seal
Furnace fire extinguishing event, guarantees that boiler continues to run after slagging.After dragveyer is repaired, cover board can be quickly removed, restores fishing
Slag machine normal operating conditions.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the connection schematic diagram of track and cover board；
Fig. 4 is the side view of Fig. 3.
It is marked in figure as follows: track 1, cover board 2, seal closure 3, flanging 4, push-and-pull orifice plate 5, push-and-pull hole 6, dragveyer 7, slag well
8, water sealing skirt 9, chain 10, dragveyer scraper plate 11.
Specific embodiment
The utility model is made of track 1, cover board 2, seal closure 3.
Fig. 1,2 displays, multiple groups track 1 are welded on edge on 7 shell of dragveyer, and multiple groups track 1 is located at adjacent slag well 8
The water sealing skirt 9 of at neutral gear and outer end slag well 8 is at 7 shell both ends neutral gear of dragveyer between water sealing skirt 9, and track 1 is perpendicular to fishing slag
