Abstract

The utility model relates to a dust collector for a road construction drier, which comprises a drier, a bag type dust collector, and a pipeline. The air inlet of the bag type dust collector is connected with the drier through the pipeline. The air outlet of the bag type dust collector is connected with a fume exhaust pipe. A cyclone dust collector is additionally arranged between the bag type dust collector and the drier through the pipeline. Balance type discharge valves are additionally arranged on the bottom of the cyclone dust collector and the bottom of the bag type dust collector. The lower parts of the discharge valves are connected with a conveyor. The utility model can adapt to most of the driers of a mixing machine set in China to eliminate smoke and dust and to reclaim valuable materials without a special storehouse, and has the advantages of compact structure, easy maintenance, small ground occupation, and obvious dust collection effect.

Description

The dryer dust collecter of building the road

The utility model belongs to the highway supporting dryer dust arrester installation of mixing machine of building the road, and specifically is a kind of dryer dust collecter of building the road.

The present domestic highway employed dust arrester installation of the supporting dryer of mixing machine of building the road, two kinds of forms are only arranged, the one, wet method, even the dust that dryer produces makes its proportion increase behind spray and falls in the dust hopper, form with mud enters sedimentation basin then, water is reuse after filtering, mud then falls by manually digging out to topple over, and there has been waste water resource in this method, easily causes secondary pollution, there is the value material not recycle, floor space is big, and the 2nd, dry type is about to dusty gas drying machine stove tail and directly enters the dry dust collection device by pipeline, dusty gas after making purification under the filtration operation of filter bag is discharged through flue, dust falls in the ash bucket and discharges, and the equipment that this dry method adopted relies on external import substantially, so existed investment big, the use cost height, safeguard, inconvenient operation, the defective that need establish special-purpose storehouse.

The purpose of this utility model is to provide a kind of advantage that fully utilizes the device that above-mentioned dual mode adopts, do not need special-purpose storehouse, can adapt to China's most of mix unit dryer smoke abatement and dust control and the recovery of value material be arranged, compact conformation, the dryer dust collecter of building the road that floor space is little.

The utility model is realized by some technical schemes:

It is a kind of dryer dust collecter of building the road, comprise dryer, bag filter and pipeline, the air inlet of bag filter connects dryer by pipeline, air outlet connects smoke exhaust pipe by blower fan, between bag filter and dryer, install rotoclone collector additional by pipeline, and installing the balanced type discharge valve additional in the bottom of rotoclone collector and bag filter, the bottom of discharge valve connects conveyer.

On the upper body of described rotoclone collector explosion-protection equipment is installed.

By-pass line is installed on the top of described bag filter, and by-pass line connects little screen-wall formula blowback machine that shakes.

The utility model compared with prior art, owing to being designs at homemade a large amount of 60～30T/H mixer assembly cover, have and the homemade same special-purpose storehouse that do not need, used for reference the principle of equipment component of the dry dust collection method of external inlet device again, so have the following advantages:

1, do not need special-purpose storehouse, can adapt to China's most of mix unit dryer smoke abatement and dust control and the recovery of value material is arranged.

2, compact conformation, be easy to safeguard, floor space is little.

3, dust collection effect is obvious.

Describe in further detail below in conjunction with accompanying drawing.

Fig. 1: the utility model embodiment draw bail schematic diagram.

The left view of Fig. 2: Fig. 1.

Among the figure: 1 smoke exhaust pipe, 2 bag filters, 3 pipelines, 4 rotoclone collectors, 5 explosion-protection equipments, 6 mix unit elevators, 7 balanced type discharge valves, 8,11 conveying worms, 9 dryers, 10 main intake stacks, the reverse hair-dryer of 12 little screen-walls that shake

Elder generation is connected as one the matched dryer 9 of highway road machine mixing machine, rotoclone collector 4 and bag filter 2 usefulness pipelines 3 as shown in the figure and fixedly mounts before use, enter rotoclone collector 4 with the high temperature dust gas in the dryer 9 by main intake stack 10 tangent lines by mixing machine, under the effect of rotoclone collector 4 inner filtration nets, the dust of contained larger particles just falls into ash bucket along inwall in the gas, under the control action of balanced type discharge valve, fall on the conveying worm 8 again; The dusty gas that contains small dust after rotoclone collector 4 purifies enters bag filter 2 through pipeline 3 again, within it under the effect of portion's filter bag, the dust of larger particles is filtered to the outside of filter in the small dust, the reverse hair-dryer 12 every interval certain hours of little screen-wall formula of shaking are by by-pass line oppositely blowing in bag filter 2, meanwhile little device work of shaking, the dust that adsorbs on the filter bag is shaken, by wind in the ash bucket of bottom, fall on the conveying worm 8 along the balanced type discharge valve 7 of ash bucket bottom, by conveying worm 8,11 deliver to mix unit elevator 6 with dust, dust is reclaimed use, after gathering dust of bag filter 2 handled, the comparatively pure gas that meets national standard was discharged in the atmosphere through smoke exhaust pipe 1 and goes; Because explosion-protection equipment 5 is installed on rotoclone collector 4, when excessive the or temperature of the pressure in rotoclone collector 4 is too high, explosion-protection equipment 5 promptly opens step-down automatically, with temperature, so can because of the pressure in the rotoclone collector 4 or temperature is not too high do not blast, guaranteed operator's personal safety, bag filter 2, rotoclone collector 4 and the reverse hair-dryer of little screen-wall that shakes that adopts in this device is all the equipment of prior art.

Claims
