Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It is it should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
Referring to shown in Fig. 1-3, a kind of boiler synchronization lifting deashing mechanism, including：
Lift drive mechanism including deashing frame 12 and the driving deashing frame reciprocal vertical lifting, the lifting are driven
Motivation structure includes four drive chains 7 being synchronized with the movement and four drive sprockets being sequentially connected respectively with the drive chain
6, drive sprocket described in each two is connected by a drive shaft with a commutator 5 respectively, the other end of each drive shaft with
One band base bearing 4 connects, and each commutator is connected by a transmission shaft 3 with a shaft coupling 2, the shaft coupling 2 with together
One motor reducer 1 connects；One end of the every drive chain, which is connected to, to be cleaned on frame 12, and one is formed with cleaning frame
A entirety, drive chain and cleaning frame are synchronized with the movement together.
The soot blower being located at boiler tip position 13 is further included, soot blower includes multiple purging nozzles 11, access
External compression air, for automatically opening up air intake valve when deashing frame 12 is reached apart from boiler 13 a distance of tip position
To carry out pulsed purging to the steel brush on whole deashing frame.
Wherein, motor reducer 1 provides power by shaft coupling 2, transmission shaft 3 and commutator 5, while drives each driving
Drive sprocket 6 on axis synchronously rotates, totally four groups of sprocket wheel-link chain mechanisms, and the rotation of drive sprocket 6 drives vertical hard-drive chain
The up and down motion of bar 7, one end (can such as pass through axis pin and stent or other fixed forms) of drive chain are connected to cleaning frame
On frame 12, the two, which is formed, is hinged, and forms an entirety with cleaning frame 12, drive chain 7 is transported with 12 1 lifting of frame is cleaned
It is dynamic.
When running up a high position for boiler due to deashing frame, 7 device of drive chain stretch out boiler outside it is longer (boiler
The stroke of height or clearing apparatus determines chain length), so setting one to stablize branch with what is be oriented in the exterior of boiler
Support frame frame 8, ensures the stabilization of drive chain and accurate operation.
The support frame 8 is rectangular frame, including two risers 82, is oppositely arranged, has multiple between two risers
Have two opposite installing plates 86 between transverse slat 81 setting up and down, described two risers, each installing plate with it is corresponding
Riser between two groups of type leading wheel frameworks 83 are installed, the type leading wheel framework includes two directive wheels 84, is oppositely arranged, leads to respectively
Wheel carrier is crossed on the riser and installing plate, drive chain between described two directive wheels by carrying out oscilaltion shifting
It is dynamic.
Multiple purging nozzles, for accessing external compression air, can beat automatically when deashing frame reaches top
Drive air valve into and pulsed purging is carried out to the steel brush of whole deashing frame, steel brush is clean, the elasticity of steel brush is kept, is subtracted
Resistance between small steel brush and heat-exchanging tube bundle, so as to ensure that deashing process is smooth efficiently.
Wherein, the compressed air valve of the soot blower and motor reducer respectively with control system or controller phase
Connection, is automatically controlled by the control system or controller and is turned on and off.
The top that boiler is up in boiler tube bundle deashing frame limits a high position, (can limit and be set at the position 9 of a high position
High-order limit switch, is connected with control system or controller, after high-order limit switch is touched) motor reducer stopping fortune
OK, while the Air blowing valve of controller or control system (such as microcontroller) control high pressure air is opened, and begins through purging
Nozzle purging cleans the steel brush on frame, cleans up the dust stratification above steel brush.After steel brush dust stratification purging, it is anti-that controller starts motor
Turn, deashing frame is run down to by vertical chain-sprocket mechanism low level is limited in boiler, (position of low level can be limited
Setting low level limit switch at 10 is put, is connected with control system or controller, after low level limit switch is touched) controller
Or control system, start motor reversal, and drive cleaning frame to move upwards, it is high-order to the limitation of boiler top, complete one
Impulse stroke.Meanwhile the time of whole stroke and the frequency can be set according to different operating modes.
The purging nozzle is provided at the top of boiler, for accessing steel brush of the external compression air to deashing frame
Dust stratification purging.When deashing frame movement reaches top, open Air blowing valve and the steel brush of whole deashing frame is purged, by steel
Brush clean, keep the elasticity of steel brush, reduce the resistance between steel brush and heat-exchanging tube bundle, so as to ensure the smooth height of deashing process
Effect.
The present invention, can by using elevating drive mechanism of the synchro-lift system of sprocket wheel-chain as cleaning frame
Enough ensure to clean the synchronous operation during frame movement, also ensure that and clean frame when upwardly or downwardly running all without going out
Existing bite situation occurs.
In addition, adding the purge system of intelligent control in systems, when cleaning frame arrival highest is spacing, open automatically
Dynamic purge system, purges to cleaning the steel brush in frame, ensures steel brush elasticity, extends the service life of steel brush, improves steel
Brush cleaning efficiency.
