Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation.
Waste incineration is passed sequentially through by fire grate driving structure in the regional on fire grate 4, burning process, drives fire grate
Motion, rubbish vibrates and moved forward on fire grate, can obtain abundant burning.When rubbish enters another area by an area, rise
To the one big effect stood up and broken up, until burning discharge burner hearth.SUN types fire grate is by drying fire grate 41, combustion grate 42, burning
Fire grate 43 is constituted, the 1st section of dry fire grate 41 be mainly used in dry, the 2nd section of combustion grate 42 be mainly used in burning, the 3rd section burn
Fire grate 43 is used to burn completely.Sufficient drop is provided between each section, rubbish is broken up using the drop, stirred.
In the utility model, fire grate driving structure 44 is hydraulic-driven or pneumatic driving structure, including driving cylinder 441 drives
Dynamic cylinder 441 connects the push rod 443 for promoting fire grate to move forward and backward by connecting rod 442.Provided with control on the entrance point pipeline of driving cylinder
The proportional flow control valve of hydraulic oil processed, or the air valve of air pressure is controlled, the actuating speed of fire grate is burned by proportional flow control valve or gas
Valve is adjusted.
It is preferred that, connecting rod 442 has two connection ends, for the V-structure bar with certain angle, V-structure bar middle part
It is rotatably coupled to by rotating shaft on bearing, one end connection driving cylinder 441 of V-structure bar, other end connection push rod 443.
As shown in Figure 2, driving cylinder 441, connecting rod 442 and push rod 443 are in M type link positions, during driving, with rotating shaft position on bearing
For center of rotation, it is push rod 443 towards fire grate direction that the tailpiece of the piston rod of driving cylinder 441, which protrudes through the bearing change of connecting rod 442,
It is mobile, so as to promote fire grate to move.
In the utility model, it is preferred that provided with connection shield 444 on push rod 443, back and forth promoted with mitigating fire grate
Vibration in journey.
In the utility model, it is further preferred that drying fire grate 41, combustion grate 42 and the row face of burn-out grate 43 are downward
It is in tilted layout, by the inclined mode in row face of fire grate, makes rubbish under gravity, by the drying fire grate of eminence through combustion furnace
Arrange and transported to burn-out grate, effectively realize the course of conveying of rubbish on fire grate from the front to the back, from top to bottom, can be achieved with compared with
The fire grate driving structure of small driving force, drives the motion of whole fire grate, plays a part of reducing energy consumption.And rubbish can be realized simultaneously
Drying on fire grate, burning and fully burn.
Support swing rod 45 is equipped with below each fire grate.Support swing rod 45, support pendulum are respectively connected with the both sides of fire grate 4
One end of bar 45 is hingedly connected to the other end on fire-grating seat and is hingedly connected to fire grate side, to obtain preferable supporting role, protects
Demonstrate,prove the stable shake process of fire grate.
Independent inlet air plenum is provided with below per one-level fire grate.Control air mass flow is equipped with the pipeline of each inlet air plenum connection
Flow air door.Fire grate bottom is not alter wind between several independent air compartments, each air compartment mutually, and each air compartment is provided with independent flow wind
Door.Flow air door can individually be adjusted individually individually with a control actuator according to each fire grate institute to the combustion case in region
The aperture of air door, to realize optimal combustion efficiency.
Inlet air plenum is connected with grey blower fan, and the fine particle of air compartment is fallen into by fire grate gap, is introduced by deashing blower fan
High-pressure blast is blown into slag releasing channel by putting grey passage.
In fire grate design, by controlling thickness of feed layer, reduction fire grate is exposed, improves durability；Each fire grate has independent
Inlet air plenum, air, which is evenly distributed, improves flammability；Grey reduction is fallen in fire grate gap, and clinker ignition loss is improved, less than≤
3%, generally 1-2%.Using the utility model drive mechanism, fire grate jam can be avoided, come off, fire grate each other without friction,
Reduce abrasion, drive it is bad.Flameholding, the activity time of fire grate is automatically adjusted by automatic combustion control system.
The utility model fire grate drive control step, is driven using fire grate driving structure, comprised the following steps：
1) during the normal use of fire grate, driving cylinder is started, control fire grate travels forward TM1=8~10 second and backward
TM2=8~10 second are moved, travels forward and is spaced TM3=1 seconds between moving backward；
2) fire grate stops, and dwell time TS, fire grate does shake action in dwell time；So operate and be advantageous in that：
The rubbish bed of material can be made more uniform；All burnt is more fixed.And then improve incineration firing effect, quantity of steam is tended towards stability.
Times N is shaken in trial operation no less than once.Controlled to shake times N according to the combustion case in stove.If N
It is too small then meaningless or to no effect, really shaken too frequently as N is excessive, then rubbish excessively will fully burn, and make
The all burnt for obtaining rubbish moves up and (deviates after-flame section fire grate), influences integral combustion effect.It is preferred that N be 3 to 10 times.
Shake action is made up of shake advance time tm1, shake interval time tm3 and shake backoff time tm2, is passed through and is driven
The dynamic cylinder control shake time, it is 1 second to shake interval time tm3.
Between each shake action, fire grate interval stops, and shakes dwell time t s, shakes dwell time ts=(TS-
(tm1+tm2+tm3)×N)/(N+1)。
Fig. 3 is the sequential that shake is acted, wherein TM1：The advance time；TM2：Backoff time；TM3：Interval time=1sec；
TS：Dwell time (variable)；tm1：Shake the advance time；tm2：Shake backoff time；tm3：Shake interval time=1sec；
ts：Shake dwell time=(TS- (tm1+tm2+tm3) × N)/(N+1)；N：Number of times (variable) is shaken, it is dynamic when Fig. 3 is N=3
Make.
The utility model fire grate driving structure and fire grate drive control step, simple in construction, convenient operation and control can be effective
Waste incineration efficiency is improved, with stronger practicality and preferable application prospect.
The utility model is exemplarily described above in conjunction with accompanying drawing, but the utility model be not limited to it is above-mentioned
Mode, as long as conceiving the improvement of the various unsubstantialities carried out with technical scheme using method of the present utility model or directly applying
In other occasions, all fall within protection domain of the present utility model.
