The beneficial effects of the invention are that:
1, the atomization in dust removal and filtration mechanism using ante-chamber carries out humidifying poly- dirt, reaches dust removing effects, and atomization covering is closeer
Collection, poly- dirt effect is good, can save water resource, while cooperating the filter at low temperature of back cavity, low temperature while filter screen and floating dust
Grain is used as carrier, and the steam (air script humidity and atomized steam) be conducive in air is gathered into drop (dew), reduces steam
It is outer to dissipate, water utilization rate, while the absorption using water droplet to floating dust are improved, the filter capacity of filter screen, filter effect are improved
More preferably, and cleaning effect is carried.It can control gas flowing by air guide solenoid valve and exhaust solenoid valve, the setting of elastomeric bladder can be swollen
Swollen cooperation air guide solenoid valve uses, and increases the space of ante-chamber, can control the processing time, while providing time interval for refrigeration.
Ground dedusting mechanism is (basic for opposed flattened construction road surface, the more coarse cement surface tentatively constructed etc.
Dirt road, the biggish ground of hollow etc. are not used) dust collection processing is carried out, the viscosity for being watered dilution stirring is placed in storage mud box
Soil (forms thicker mud), and dust, the little particle rubble etc. on ground are collected using the attaching property of sticky soil, repeats benefit
With, can save water resource (be watered with mud can long-time large area use, largely sprinkling water compared to traditional large area can play
Significant water-saving result).Sticky soil itself is not easy to form floating particle simultaneously, and integraty is good after dehydration consolidation, can fill and lead up coarse
Surface, the part on stand-down not will form fugitive dust, while be capable of the floating dust in continued adhesion absorption later period, while to coarse
Surface forms and fills and leads up protection, makes coarse surface is not easily damaged to fall off, is further reduced the generation of floating dust particle.And it constructs for a long time
After sticky soil collection it is also more convenient, and be not likely to produce a large amount of fugitive dusts.The setting of rear side rubber flap can scrape flat-pushing
Move extra sticky soil；
The storage mud box of ground dedusting mechanism is opposite with the exhaust pipe of dust removal and filtration mechanism, can be in the gas being finally discharged
The floating dust missed carries out absorption dedusting again, while exhaust passage further extends in installs case, thereby increases and it is possible to pass through rotary broom
Dedusting is adsorbed again；
2, the setting of cleaning shoe can by rotary broom part mud and the small crushed stone attached etc. scrape off, and flow to
It stores up in mud box；
3, biggish power work can be used in atomizing module, and the setting of water supply pipe is convenient to moisturizing；
4, rubber flap can scrape extra mud, and rubber flap can be triangle, using slope lifting mud, and by
Collecting box is collected.

Be gathered into dew, and be attached on 5 inner wall of back cavity, strainer up or down is sink to bottom, reduce steam directly drift, aggregation utilize
Absorption depositing dust is carried out, elastic membrane 8 bounces back therewith, closes air guide solenoid valve 7 and exhaust solenoid valve 18 after handling a period of time, carries out
The repetition of operating procedure.Dew, which is attached on filter screen 16, can be improved filter effect, and biggish filter screen 16 can utilize water
The raisings such as covering filter rank, and water droplet not will cause direct closure.Finally by the air of dust removal and filtration by being vented
Pipe 17 is discharged, and blows to the mud in storage mud box 22.The utilization of water resource is improved for aggregation steam, refrigeration equipment 14 needs biggish function
Rate refrigeration, in order to meet the air-flow of flowing, therefore the rate of exhaust fan 12 should control according to the actual situation relatively low
Working condition.Air guide solenoid valve 7 and exhaust solenoid valve 18 can carry out the cooperation of switch control according to practical operation situation.
When carrying out absorption dedusting to ground using ground dedusting mechanism, the mud of sticky soil is stored in storage mud box 22,
It opens slush pump 24 and extracts mud out of storage mud box 22, and be more uniformly sprayed at the table of rotary broom 23 by cement spray head 26
Face, when being moved, rotary broom 23 is then formed with ground face contact and is rolled, and is continuously added new mud, extra mud in the middle part of front
Slurry can then fall in storage mud box 22 and (mud amount can be effectively controlled using rotary broom 23, and be convenient for dust, powder collection),
Rotary broom 23 carries mud when being contacted with ground, adsorbs ground dust using mud, ground can also attach mud, the rubber of rear side
Scraper plate 27 can the deformation of certain adaptability adapt to ground and carry out scraping mud collect or persistently push mud.Remain in ground little groove
Mud can continue to realize and fall the collection of the position dust, avoid the formation of fugitive dust.
The slurry content of top can be struck off when rotary broom 23 rolls, be convenient to update, and scrape by the setting of cleaning shoe 28
28 front end of mud plate storage mud box 22 above, carry dust, small crushed stone particle mud then fall to store up mud box 22 in, mud can be followed
Slurry is utilized together.Small crushed stone particle should not influence the work of slush pump 24, big rubble should be removed in advance by other way or
It is mobile, or can be on cleaning shoe 28 or setting sieve in storage 22 upper end of mud box is filtered protection.
Subplate can be increased in the left and right sides of rubber flap 27 and carry out baffle, when so that the mud struck off is more, along slope
It moves up and collecting box 31 is entered by mud discharging mouth 30.
