Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Shown in Fig. 1-2, a kind of reciprocating deashing mechanism of waste heat boiler, including：
Mobile deashing frame 2 and the Pulley lift of the driving deashing frame reciprocal vertical lifting can be vertically moved up or down
Structure, the Pulley lift structure include the main shaft 4 of single motor driving, two output pulleys 3 being mounted on main shaft, each described
Pulley tool is exported there are two pulley body, two pulley bodies the steel cable 5 through connection and are arranged in 4 both sides of main shaft respectively
Four leading blocks 7 formed and be sequentially connected, one end of the steel wire rope connect with output pulley, and the other end pass through described in lead
It is fixed with deashing frame after to pulley；
It is located at number row's soot blower of boiler top layer, it includes multiple purging nozzles 1 often to arrange soot blower, for accessing outside
Compressed air can automatically open air intake valve when deashing frame reaches top and carry out pulsed to the steel brush of entire deashing frame
Purging, steel brush is clean, the elasticity of steel brush is kept, reduces the resistance between steel brush and heat-exchanging tube bundle, to ensure deashing mistake
Cheng Shunchang is efficient.
The deashing frame 2 realizes lifting by the Pulley lift structure under the driving of motor 8, carries out deashing operation,
When the deashing frame 2 rises to corresponding position, by the purging nozzle 1 being connect with the compressed air pipe line of compressed air source
Compressed air is introduced, carrying out spray to the steel brush on deashing frame clears away grey operation.Specific each leading block 7 is corresponding installation
Top in the position at four angles of deashing frame is moved synchronously respectively by the steel wire rope of connection 5 by the control of main shaft,
And realize moving synchronously for four angles for controlling deashing frame.
The purging nozzle 1 is setting boiler top layer, the steel brush for accessing external compression air to deashing frame
Dust stratification purging.When deashing frame movement reaches top, opens Air blowing valve and the steel brush of entire deashing frame is purged, by steel
It brushes clean, keeps the elasticity of steel brush, reduce the resistance between steel brush and heat-exchanging tube bundle, to ensure the smooth height of deashing process
Effect.
In the utility model, the Pulley lift structure uses single main shaft export structure, ensures drive coordination, uses
