Description

Spraying and blowing system roll-over pulsed dust collector
Technical field:
The utility model relates to a kind of cleaner, is specifically related to a kind of spraying and blowing system roll-over pulsed dust collector.
Background technology:
At present, fiber bag precipitator is widely used in purifying the dusty gases that industry produced such as metallurgy, mine, chemical industry, cement, generating, grain processing in industry.The operation principle of fiber bag precipitator is, dusty gas introduced deduster and make it see through the filter bag of being located in the deduster, and grit promptly is blocked and stays the filter bag surface, forms a dust layer.Pure air then flows out deduster by filter bag smoothly.The difference of the direction that flows through according to gas can be divided into fiber bag precipitator two kinds of outside filtering type and inward flow filtration-types, and when outer filter bag type deduster filtered, gas passed filter cloth by the filter bag outside and flows to filter bag inside, and grit is attached to the outer surface of filter bag; When the inward flow filtration-type sack cleaner filtered, gas passed filter cloth by the filter bag inboard and flows to the filter bag outside, on the inner surface of grit attached to filter bag.
After operation a period of time, the dust layer of meeting dirt surface accumulation of the filter bag of fiber bag precipitator is more and more thicker, and the drag losses of deduster is increased, and therefore, one section of fiber bag precipitator operation is after the time, need carry out deashing.
The purge mode of existing exterior sieve type bag-type dust remover mainly adopts pulse jetting deashing, it makes pressure-air is blown into filter bag at a high speed in the of short duration time, produce and the reverse blowback air-flow of filtered airflow, make and produce pulse expansion shake in the filter bag, the filter bag wall obtains very high outside acceleration, thereby shakes off dust.This mode belongs to dynamic deashing.This kind purge mode is that the variation by the filter bag profile comes off the dust layer attached to the filter bag surface.But, for a long time, this mode of employing repeatedly can accelerate the fatigue of filter bag, shortens the service life of filter bag significantly.With regard to needing frequent filter bag is overhauled, safeguard like this.But existing deduster in being installed in of its filter bag in the casing, enters in the casing in the manhole that the repair and maintenance of filter bag therefrom is provided with on the casing, maintenance, filter bag inconvenience is very changed in maintenance, and dust is more in the middle casing, the temperature height, and the maintenance environment is very abominable.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of spraying and blowing system roll-over pulsed dust collector, its upper box is provided with loam cake, loam cake can open, and filter bag therefrom takes out in the casing, like this, the maintainer can open loam cake, above deduster, filter bag is taken out, and then maintenance, filter bag changed, improved operating efficiency greatly, operation is also more easily simple.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of spraying and blowing system roll-over pulsed dust collector, it comprises upper box 1, middle casing 3, filter bag 8, lower box 4, ash discharge cone 5 and discharging wind stopping device 6, ash discharge cone 5 lower ends are provided with discharging wind stopping device 6, ash discharge cone 5 upper ends are provided with lower box 4, be provided with inner core 19 in the lower box 4, lower box 4 is provided with middle casing 3, in the middle casing 3 filter bag 8 is housed, middle casing 3 is provided with upper box 1, wherein: described upper box 1 is provided with loam cake 11, loam cake 11 passes through bolting with upper box 1, and loam cake 11 is connected by hinge 9 with upper box 1.
Further, described loam cake 11 comprises cover plate 13, lid 12, card 16 and anti-blow cleaning dust device, and cover plate 13 is contained on the lid 12, and lid 12 lower ends are provided with card 16, and card 16 is provided with the anti-blow cleaning dust device.
Further, described anti-blow cleaning dust device comprises impulse electromagnetic valve 14, air chamber 15, air jet pipe 17 and nozzle 18, impulse electromagnetic valve 14 is arranged on the card 16, air chamber 15 is arranged on card 16 times, impulse electromagnetic valve is connected with air jet pipe 17 14 times, air jet pipe is connected with nozzle 18 17 times, and nozzle 18 is suitable for reading corresponding with filter bag 8.
Further, described card 16 circumference are provided with bolt hole, and it is shaped as " n " shape.
Further, described filter bag 8 upper ends are provided with connecting plate 10, on the top board of casing 3, are provided with sealing gasket between the top board of connecting plate 10 and middle casing 3 during connecting plate 10 is contained in by bolt.
The beneficial effects of the utility model are:
The utility model is simple in structure, with low cost, its upper box is provided with loam cake, loam cake can open, filter bag therefrom takes out in the casing, like this, the maintainer can open loam cake, above deduster filter bag is taken out, and then maintenance, change filter bag, improved operating efficiency greatly, operation is also more easily simple, the bolt hole that is provided with on the card circumference be shaped as " n " shape, can be easy to open loam cake, so just reduce maintainer's labour intensity, also can prevent losing of bolt and nut.
