Description
Technical field
The present invention relates to pitch processing technique fields, more particularly, to a kind of dust pelletizing system of asphalt concrete mixer.
Background technique
It is well known that concrete mixing plant can generate a large amount of dust in production, the running environment of mixing plant is extremely disliked
Bad, often dust gathers.Bituminous concrete is commonly called as bitumen concrete, and artificial selection has a mineral aggregate of certain gradation composition, rubble or
Grating gravel, aggregate chips or sand, miberal powder etc., and a certain proportion of bitumen for road use material, under the conditions of strict control made of mixing
Mixture.
Asphalt concrete mixer is being stirred using the work station for making pitch after aggregate and mixture stirring
And a large amount of dust is easy to produce during discharging, so can be generally dusted using exhaust dust device with bag to air.And
The working principle of existing sack cleaner is that dusty gas is introduced into deduster and passes it through the filter bag in deduster,
Grit i.e. intercepted stay in outside filter bag is located in deduster, forms a dust layer.Pure air is then thereafter let out by filter bag
Deduster.
Prior art among the above have the following deficiencies: bag filter mainly to the environment around mixing plant into
Row dedusting, and a mixing bowl of mixing plant is the major sources of dust, bag filter can to the environment where mixing plant into
Row dedusting, and cannot be handled from the source of dust.Therefore, the densely covered problem of the dust of mixing plant is urgently broken off relations.
Summary of the invention
The object of the present invention is to provide a kind of dust pelletizing system of asphalt concrete mixer, the source to a mixing bowl is reached
The effect being dusted prevents mixing plant dust from gathering.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of dust pelletizing system of asphalt concrete mixer, including a mixing bowl are connected with finished product hopper, finished product hopper on a mixing bowl
On be connected with main bag filter, dust gathering arrester is connected on a mixing bowl, is connected with flue dust surge bunker on dust gathering arrester, flue dust is slow
It rushes in storehouse and is provided with the dust-extraction unit of dust and flue gas separation, be connected on flue dust surge bunker and flue gas is passed into main cloth bag removes
Snorkel in dirt device.
By using above scheme, rubble or grating gravel, aggregate chips, sand and miberal powder etc. are added in a mixing bowl,
Rubble or grating gravel, aggregate chips, sand and miberal powder etc. will be stirred evenly in a mixing bowl, a mixing bowl stirs rubble or grating gravel
The flue dust of the generations such as stone, aggregate chips, sand and miberal powder is inhaled into flue dust surge bunker through material passing tube, the dedusting in flue dust surge bunker
Device can separate travel fatigue and flue gas, and the flue gas after separation is passed into main bag filter and filters again, after mixing evenly
Rubble or grating gravel, aggregate chips, sand and miberal powder etc. be delivered in finished product hopper, main bag filter can generate blanking
Dust etc. be drawn into main bag filter and be filtered again, the source that can generate flue dust to a mixing bowl be handled, from
And it can prevent mixing plant dust from gathering.
The present invention is further arranged to: passage, passage and collection are connected between the dust gathering arrester and flue dust surge bunker
The junction of dust hood is provided with strainer.
By using above scheme, due to being in negative pressure state in flue dust collecting storehouse, the dust etc. in dust gathering arrester can be inhaled
Entering into flue dust collecting storehouse, strainer can prevent flue dust collecting storehouse that material of larger particles etc. is drawn into flue dust collecting storehouse,
It can also prevent the feed blocking passage of bulky grain.
The present invention is further arranged to: the dust-extraction unit is backpulsing bag filter.
By using above scheme, the cloth bag of backpulsing bag filter can separate dust and flue gas, and flue gas is through anti-
Flush bag-type dust collector is passed through outside flue dust surge bunker, and a large amount of dust is adsorbed on the outside of cloth bag, to make Bag filter effect
Dust on cloth bag can be blown into flue dust surge bunker by decline, backpulsing bag filter, not influence the filtering effect of cloth bag
Fruit.
The present invention is further arranged to: the bottom of the flue dust surge bunker is connected with feeder pipe, and feeder pipe and discharge nozzle connect
It is logical.
By using above scheme, filtering can be passed into discharge nozzle by feeder pipe in the dust in flue dust collecting storehouse,
Then quiet discharge nozzle, which enters in main bag filter, carries out secondary filter to it.
The present invention is further arranged to: being connected with ash-valve on the feeder pipe.
By using above scheme, ash-valve can be turned off when not working convenient for artificial control, prevent from discharging
Dust in pipe is drawn into flue dust surge bunker by counter.
The present invention is further arranged to: the taste device of dispelling handled flue gas is connected on the snorkel.
By using above scheme, since a large amount of odor gas can be mixed in the flue gas that filters out, directly flue gas is arranged
Enter and will cause air pollution into atmosphere, taste device of dispelling can purify flue gas, prevent flue gas from causing air pollution.
The present invention is further arranged to: the taste device of dispelling includes plasma deodorizing device and activated-carbon device.
By using above scheme, it can aoxidize in a very short period of time, decompose methyl mercaptan, ammonia, hydrogen sulfide, ethers, amine
Deng the pollution foul smell factor, open the chemical bond of volatile organic compounds, ultimately generate carbon dioxide and water etc. stablize it is harmless small
Molecule, to reach purification air；Active carbon has stronger adsorptivity, and the adsorptivity of active carbon is to utilize porous activity
Charcoal can absorb nocuousness in air, especially gas, and then achieve the effect that, deodorization and air cleaning, carry out to air secondary
Purification.
The present invention is further arranged to: be connected with dust collection storehouse on the main bag filter, dust collection storehouse with stir
It mixes and is connected with feed pipe between cylinder.
By using above scheme, dust collection storehouse can be collected the dust filtered in main bag filter, send
Expects pipe returns to the dust of collection in a mixing bowl, and dust is enable to utilize again, avoids the waste of dust.
In conclusion the invention has the following advantages:
1. being connected with flue dust surge bunker on dust gathering arrester by being connected with dust gathering arrester on a mixing bowl, being provided in flue dust surge bunker
The separator that dust and flue gas are separated is connected with the ventilation being passed into flue gas in main bag filter on flue dust surge bunker
Pipe, the source that can generate flue dust to a mixing bowl are handled, so as to prevent mixing plant dust from gathering；
2. by being provided with taste device of dispelling on snorkel, since a large amount of odor gas can be mixed in the flue gas that filters out, directly
