The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of board plug type partition door and coal-burning boiler are provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of board plug type partition door, comprise the closure plate framework be located in passage, be inserted into this closure plate framework in the closure plate of isolated passage, and the closure plate be inserted in this closure plate framework for intercepting closure plate is sealed up a door, and described closure plate is sealed up a door and is located on closure plate framework.
Described closure plate is sealed up a door and closure plate frame articulation, and
Parallel with closure plate frame plane when opening, crossing with closure plate frame plane during closedown.
Described closure plate is sealed up a door vertical with closure plate frame plane when closing.
Described closure plate is sealed up a door and the pivot joint of closure plate framework.
Described closure plate and closure plate framework apart,
And in described closure plate framework, offering the groove inserted for closure plate, this groove is parallel with closure plate frame plane.
A kind of coal-burning boiler, described wind pushing mechanism is connected with body of heater for the wind pushing mechanism for body of heater air feed to comprise body of heater and at least two, is provided with described board plug type partition door between described wind pushing mechanism and body of heater.
Described wind pushing mechanism comprises interconnective inlet box and primary air fan, and described primary air fan is connected with body of heater by board plug type partition door.
Described wind pushing mechanism is provided with two altogether.
Compared with prior art, the utility model has the following advantages:
1) the simple input cost of the structure of board plug type partition door is low, adopts closure plate to seal up a door to intercept closure plate to be inserted into mode in closure plate framework, implements flexibly, and when dividing plate does not insert, can keep good air-tightness in the side direction intercepting framework.
2) closure plate is sealed up a door employing cementation method, can open closedown neatly, facilitate closure plate to insert.
3) closure plate and closure plate framework are separation design, can reduce taking up room of the application Ge door, and closure plate is antirust for subsequent usely just can afterwards.
4) the application's coal-burning boiler is provided with board plug type partition door between wind pushing mechanism and body of heater, inserts closure plate, guarantee tightly not leak, improve safety in utilization and reliability after single blower fan is stopped transport.
