Description

The Environmental-protection dust removal device of asphalt equipment
Technical field
The present invention relates to a kind of Environmental-protection dust removal device of asphalt equipment, specifically be used for removing the bitumen flue gas of pitch clout.
Background technology
Asphalt mixing plant began existing more than 20 year from introducing China, the no matter equipment of import or domestic equipment, and all have a common problem: the dust of main facilities of mix storied building body and the discharging of the bitumen flue gas in the production process are difficult to control.When particularly giving out light clout in the storehouse behind the end-of-job, contain following high temperature (140 ℃ ~ 160 ℃) dried particles of a large amount of diameter 0.075mm in the clout, therefore can produce a large amount of dust when discharging, dust is quite large to the pollution of equipment and environment.
Three kinds of methods of the general employing of present asphalt mixing plant are processed the dust in the clout: the one, and atomized water spray in the time of the discharging clout, this kind method poor effect, water smoke is difficult to cover dust; The 2nd, discharge after in clout, adding a small amount of asphalt mixing, reduced although do like this Dust Capacity, asphalt price is expensive, and the clout that has added pitch can not recycle, and can cause secondary pollution to environment; The 3rd, bitumen flue gas is introduced rotary drum drying machine remove bitumen flue gas, because the tumble drying machine negative pressure is too little, so effect is also bad.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of Environmental-protection dust removal device of asphalt equipment is provided, can remove the bitumen flue gas in the pitch clout, prevent that bitumen flue gas from polluting external environment condition, reaches the purpose of dedusting environment friendly.
According to technical scheme provided by the invention, the Environmental-protection dust removal device of asphalt equipment comprises a mixing bowl, spiral dust separater, dedusting air door, rotary drum drying machine, sack cleaner, main induced draft fan and motor, rotary drum drying machine one end connects spiral dust separater by dust removing tube, is provided with the dedusting air door in the dust removing tube.Connect sack cleaner on the described spiral dust separater, sack cleaner connects main induced draft fan by main induced duct.Described main induced draft fan connects drive by motor, it is characterized in that: also comprise draught hood, lifting draught hood, control air door, a mixing bowl lower end connects draught hood by vomit pipe, connects the lifting draught hood on the draught hood.Described draught hood one end connects spiral dust separater by taking out the dirt pipe, takes out and is provided with the control air door in the dirt pipe.
Described control air door comprises a plurality of blades, and blade is controlled by air door executer, can freely adjust the angle that blade is opened.
Described lifting draught hood comprises that skeleton is connected with connection, and weaving cotton cloth by connection between a plurality of skeletons links into an integrated entity.
Be provided with journey controller in the described lifting draught hood, by the lifting travel of journey controller control lifting draught hood.
Described dedusting air door comprises a plurality of blades, and blade is controlled by air door executer, and blade can only standard-sized sheet or full cut-off.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Can remove the bitumen flue gas in the pitch clout, prevent that bitumen flue gas from polluting external environment condition; Cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-a mixing bowl, 2-vomit pipe, 3-draught hood, 4-liftable draught hood, 5-take out dirt pipe, 6-control air door, 7-spiral dust separater, 8-dust removing tube, 9-dedusting air door, 10-rotary drum drying machine, 11-sack cleaner, 12-main induced draft fan, 13-master's induced duct, 14-motor.
The specific embodiment
Following the present invention is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1, the present invention mainly comprises a mixing bowl 1, draught hood 3, lifting draught hood 4, control air door 6, spiral dust separater 7, dedusting air door 9, rotary drum drying machine 10, sack cleaner 11, main induced draft fan 12 and motor 14.
A mixing bowl 1 lower end connects draught hood 3 by vomit pipe 2, connects lifting draught hood 4 on the draught hood 3.Described draught hood 3 one ends connect spiral dust separater 7 by taking out dirt pipe 5, take out and are provided with control air door 6 in the dirt pipe 5.Described control air door 6 comprises a plurality of blades, and blade is controlled by air door executer, can freely adjust the angle that blade is opened.Connect sack cleaner 11 on the described spiral dust separater 7, sack cleaner 11 connects main induced draft fan 12 by main induced duct 13.Described main induced draft fan 12 connects drive by motor 14.
Described lifting draught hood 4 comprises that skeleton is connected with connection, and weaving cotton cloth by connection between a plurality of skeletons links into an integrated entity.Described skeleton is weaved cotton cloth by connection and is realized flexible up and down function.Be provided with journey controller in the described lifting draught hood 4, by the lifting travel of journey controller control lifting draught hood 4.
Rotary drum drying machine 10 1 ends connect spiral dust separater 7 by dust removing tube 8, are provided with dedusting air door 9 in the dust removing tube 8.Described dedusting air door 9 comprises a plurality of blades, and blade is controlled by air door executer, and blade can only standard-sized sheet or full cut-off.
