A kind of anti-blocking ash bucket of refuse incineration exhaust-heating boiler and method of operating thereof
Technical field
The present invention relates to environmental protection cogeneration technology field, be specially a kind of anti-blocking ash bucket of refuse incineration exhaust-heating boiler.
Background technology
China's house refuse is of a great variety, in component of refuse ash content and moisture in the majority, the ash rate fire coal ash content produced in flue gas contained in the flue gas that therefore rubbish produces when burning wants many, and flue gas is through waste heat boiler, wash away waste heat boiler heating surface, cause ash to be accumulated on heating surface.
At present, in existing ash-clearing technology, all adopt and simple deashing is carried out to heating surface as purge modes such as mechanical vibrator, impulse soot blowing, steam soot blowings, when soot cleaning system breaks down, the ash in ash bucket is cumulative, is difficult to remove, ash bucket temperature finally can be caused too high, affect its normal function to use, cause blowing out, thus bring unnecessary economic loss.
Summary of the invention
The object of this invention is to provide the anti-blocking ash bucket that a kind of structure is simple, easy to operate, prevent ash bucket high temperature, avoid a kind of refuse incineration exhaust-heating boiler blocked.
The technical scheme realizing above-mentioned purpose is: a kind of anti-blocking ash bucket of refuse incineration exhaust-heating boiler, comprise ash bucket, access door is provided with in the side of ash bucket, ash bucket bottom is provided with gray moving hole, gray moving bar is connected with in gray moving hole, gray moving bar retractable enters in ash bucket, by gray moving hole during ash bucket blocking, gray moving bar carries out manual gray moving, fall into conveyer from ash bucket ash out, it is characterized in that: gray moving bar can rotate in gray moving hole, telescopic moving, the end face of gray moving bar in ash bucket is hinged with several claw bar, claw bar is connected with pre-pressing spring between any two.
Preferably when needs use gray moving bar, gray moving bar inwardly advances, and claw bar outwards opens due to the effect of pre-pressing spring, carries out manual gray moving, can outwards extract gray moving bar when finishing the work, the extruding and shrinking that claw bar is subject to gray moving bore ends edge is in gray moving hole.
Preferably the length of claw bar is the half of the length in gray moving hole.
The present invention also provides a kind of method of operating according to anti-blocking ash bucket of the present invention, comprise the steps: that the degree high according to temperature in the whether automatic ruuning situation of deashing in a period of time or ash bucket judges whether ash bucket blocks, as blocking, then stop the operation of automatic ash removing system, and then manually dust moving device carries out manual gray moving; Inside propelling gray moving bar, claw bar opens under the effect of pre-pressing spring, rotates gray moving bar and carries out gray moving work; Outwards extract gray moving bar after completing, the extruding and shrinking that claw bar is subject to gray moving bore ends edge is in gray moving hole.
The present invention can overcome the shortcoming that prior art exists, ash bucket is provided with manual dust moving device, we the degree high according to temperature in the whether automatic ruuning situation of deashing in a period of time or ash bucket can probably judge whether ash bucket blocks, as blocking, now we can take corresponding measure, as stopped the operation of automatic ash removing system, and then manually dust moving device carries out manual gray moving, manual gray moving does not need power consumption to consume gas, both blocking and the high temperature of ash bucket had been avoided, turn avoid the situation that flying dust that strength blowback causes flies upward, in turn save power consumption, simple to operate, convenient.And gray moving bar used in the present invention has multiple claw bar, drastically increase the gray moving efficiency of gray moving bar, and multi-angle, large-scale manual gray moving work can be realized.

Detailed description of the invention
As shown in Figure 1, 2, the present invention includes ash bucket 1, access door 2 is provided with in the side of ash bucket 1, entered in ash bucket 1 by access door 2 when ash bucket 1 fault and overhaul, ash bucket 1 bottom is provided with gray moving hole 3, is connected with gray moving bar 5 in gray moving hole 3, and gray moving bar 5 retractable enters in ash bucket 1, carry out manual gray moving by gray moving hole 3, gray moving bar 5 when ash bucket 1 blocks, fall into conveyer 4 from ash bucket 1 ash out.
See Fig. 3, that schematically illustrates the structural representation according to gray moving bar 5 of the present invention, gray moving bar 5 can rotate in gray moving hole 3, telescopic moving, and the end face of gray moving bar 5 in ash bucket 1 is hinged with several claw bar 6, and claw bar 6 is connected with pre-pressing spring between any two.When needs use gray moving bar 5, gray moving bar 5 inwardly advances, and claw bar 6 outwards opens due to the effect of pre-pressing spring, carries out manual gray moving, can outwards extract gray moving bar 5 when finishing the work, the extruding and shrinking that claw bar 6 is subject to gray moving hole 3 end edge is in gray moving hole 3.Preferably, the length of claw bar 6 is half of the length in gray moving hole 3.Due to the existence of claw bar 6, drastically increase the gray moving efficiency of gray moving bar 5, and multi-angle, large-scale manual gray moving work can be realized.
As follows according to the method for operating of anti-blocking ash bucket of the present invention: the degree (such as more than 450 degree Celsius) high according to temperature in the whether automatic ruuning situation of deashing in a period of time or ash bucket judges whether ash bucket blocks, as blocking, then stop the operation of automatic ash removing system, and then manually dust moving device carries out manual gray moving; Inside propelling gray moving bar, claw bar opens under the effect of pre-pressing spring, rotates gray moving bar and carries out gray moving work; Outwards extract gray moving bar after completing, the extruding and shrinking that claw bar is subject to gray moving bore ends edge is in gray moving hole.
