The utility model can clear dust on the inner surface of the dust hopper in time so as to avoid dust explosion accidents.

Description

Explosion-proof sack cleaner

Technical field

The utility model relates to a kind of exhaust dust device with bag, especially a kind of explosion-proof sack cleaner.

Background technology

Existing a kind of sack cleaner, it mainly is made of housing, filter bag, ash bucket, anti-blow cleaning dust device.The both sides, inside of housing are dirt pocket, and its top is provided with upper face plate, and the upper end of filter bag is arranged on the upper face plate, and the top of upper face plate is an air-purifying chamber.Part between the dirt pocket of enclosure interior both sides makes this part become upper and lower two Room by the swash plate that is positioned at the middle part.For the air inlet of inlet plenum, this chamber and housing front end face links, upward be discharge chamber down, the air outlet of this chamber and housing rear end face links.Ash bucket is arranged on housing bottom.After dusty gas enters inlet plenum from air inlet during work, dusty gas moves downward and enters the back that collides with it, ash bucket bottom from inlet plenum and change the direction of motion and enter in the dirt pocket of enclosure interior both sides, dust detention in the dusty gas that moves upward is purified dusty gas in the filter bag outside.Purified gas enters air-purifying chamber through upper face plate in filter bag, discharged from air outlet by exhaust blower from discharge chamber again.After the running resistance of deduster was increased to certain value, the pulse valve of anti-blow cleaning dust device was opened, and blowback wind enters in the filter bag, and the filter bag that shriveled originally expands distortion, removed the dust that the filter bag outer surface adheres to, and the dust under falls in the ash bucket clearly.After deduster work a period of time, the thicker dust of one deck is always arranged on the ash bucket inner surface.Because the existence of this layer dust, when colliding with it in the dust on the filter bag outer surface falls into this awl, the dust concentration in the ash bucket heightens, and this causes the generation of dust explosion accident easily.

The utility model content

The technical problems to be solved in the utility model provides a kind of explosion-proof sack cleaner, and this deduster can in time be removed the dust on the ash bucket inner surface, effectively prevents the generation of dust explosion accident.

For solving the problems of the technologies described above, the explosion-proof sack cleaner of the utility model, it contains housing, filter bag, ash bucket, the anti-blow cleaning dust device, the both sides, inside of housing are dirt pocket, its top is provided with upper face plate, the upper end of filter bag is arranged on the upper face plate, the top of upper face plate is an air-purifying chamber, part between the dirt pocket of enclosure interior both sides, make on this part one-tenth by the swash plate that is positioned at the middle part, two Room are inlet plenum down down, the air inlet of this chamber and housing front end face links, and upward is discharge chamber, the air outlet of this chamber and housing rear end face links, ash bucket is arranged on housing bottom, and the bottom of ash bucket is provided with ash-valve, also contains air bubble, this air bubble is arranged on the outside of described ash bucket, and the jet pipe of this air bubble is positioned at described ash bucket.

Owing on ash bucket, set up air bubble, the high velocity air of the jet pipe ejection of air bubble dashes the bottom that blows to ash bucket with the dust of ash bucket inner surface, discharge through ash-valve, the timely like this dust of having removed on the ash bucket inner surface has effectively prevented the generation of the dust explosion accident that prior art causes easily because of the thicker dust of ash bucket inner surface.

Description of drawings

Accompanying drawing is the structural representation of the explosion-proof sack cleaner of the utility model.

1. housings among the figure, 2. discharge chamber, 3. ash-valve, 4. ash bucket, 5. inlet plenum, 6. air-purifying chamber, 7. dirt pocket, 7. filter bag, 9. air accumulator, 10. pulse valve, 11. blast tubes, 12. nozzles, 13. air bubbles.

The specific embodiment

In the accompanying drawing, explosion-proof sack cleaner contains housing 1, filter bag 8, ash bucket 4 and anti-blow cleaning dust device.The both sides, inside of housing 1 are dirt pocket 7, its top is provided with upper face plate, the upper end of filter bag 8 is arranged on the upper face plate, and the top of upper face plate is an air-purifying chamber 6, the part between the housing 1 inner both sides dirt pocket, make this part become upper and lower two Room by the swash plate that is positioned at the middle part, for the air inlet of inlet plenum 5, this chamber and housing front end face links, upward be discharge chamber 2 down, the air outlet of this chamber and housing 1 rear end face links, ash bucket 4 is arranged on the bottom of housing 1, and the bottom of ash bucket 4 is provided with ash-valve 3.The anti-blow cleaning dust device is made of pulse valve 10, air accumulator 9, blast tube 11 and nozzle 12.Nozzle 12 is arranged on the blast tube 11, air accumulator 9 is arranged on the top of housing 1, one end of blast tube 11 be arranged in the air accumulator 9 and be arranged on that pulse valve 10 on this jar links, the other end of blast tube 11 is positioned at air-purifying chamber 6, nozzle 12 on it is positioned at filter bag 8 top suitable for reading, nozzle 12 quantity equate with filter bag 8 quantity.Explosion-proof sack cleaner also contains air bubble 13, and this air bubble 13 is arranged on the outside of ash bucket 4, and the jet pipe of this air bubble 13 is positioned at ash bucket 4.During work, dusty gas enters in the inlet plenum 5 from air inlet, dusty gas moves downward the back that collides with it from the bottom that inlet plenum 5 enters ash bucket 4 and changes the direction of motion, dusty gas moves upward and enters in the dirt pocket 7 of housing 1 inner both sides, dust detention in the dusty gas that moves upward is in the outside of filter bag 8, and dusty gas is purified.Purified gas enters air-purifying chamber 6 from the inner face of filter bag 8 through upper face plate and is discharged from air outlet by exhaust blower from discharge chamber 2.After the running resistance of deduster is increased to certain value, the pulse valve 10 of anti-blow cleaning dust device is opened, and compressed air makes the filter bag 8 that shriveled originally expand distortion in nozzle 12 spirt filter bags 8, dispose the dust that filter bag 8 outer surfaces adhere to, the dust under falls in the ash bucket 4 clearly.After deashing finished, pulse valve 10 cut out, and can recover the dedusting state.Owing on ash bucket 4, set up air bubble 13, the high velocity air of the jet pipe ejection of air bubble 13 dashes the bottom that blows to ash bucket 4 with the dust of ash bucket 4 inner surfaces, discharge through ash-valve 3, the timely like this dust of having removed on ash bucket 4 inner surfaces has effectively prevented the generation of the dust explosion accident that prior art causes easily because of the thicker dust of ash bucket 4 inner surfaces.
