Description
Technical field
A kind of pure-suction type dust suction box body is the utility model is related to, belongs to road sanitation equipment technical field.
Background technology
Pavement garbage is collected into dustbin by vacuum sweeper by negative-pressure air-flow entirely, the pavement garbage in the section that works mostly with
Based on dust particles, therefore whole work process vehicle cannot sprinkle water, and thus be easy to cause the dustbin front end when rubbish unloads
Easy residual garbage and discharging be easy to cause reentrainment of dust pollution.Simultaneously because vacuum sweeper must have two kinds of operation moulds of dry and wet
Formula, to adapt to all weather operations ability of overcast and rainy fine day, air passage has to meet both of which for this, this also causes air passage to be arranged
It is restricted, it is excessive to be easy to cause local pressure loss, produces unnecessary energy consumption.
The content of the invention
The purpose of this utility model is that：It is proposed a kind of can effectively suppress to unload two during ash in vacuum sweeper discharging

Air-out passage switches to wet type air passage, and the air-flow of airintake wind-tunnel enters inside wet type air passage directly through main dustbin, in wet type
The refluence effect in air passage is lower to enter air inlet, is discharged into by wind turbine in air.
In the utility model, airintake wind-tunnel enters dustbin inner section sudden enlargement after main dustbin, and air velocity is dashed forward
Drop, is separated, under rubbish guide plate and airflow function, most of sanitary fill is in babinet in effect of inertia lower part rubbish
Second half section, easy to refuse-unloading.In addition, the utility model carries out atomizing de-dusting in discharging, by dust-settling nozzle, it also avoid
Reentrainment of dust problem.
Further improve of above-mentioned technical proposal be：The wet type air passage at the air inlet along airflow direction by
Small gradually taper up is arrived greatly.Since wet type air passage is indirectly connected with wind turbine, the utility model by make the angle of throat in wet type air passage by
Small seamlessly transit is arrived greatly, it is ensured that wind speed occurs without mutation, so as to reduce the pressure loss by air passage.
Preferably, the wet type air passage, dry type are separated by partition between air passage.
Preferably, the dust-settling nozzle is conical atomization nozzle, is separately mounted at the top of the doorframe of dustbin Dump gate
And sidepiece.
Preferably, the airintake wind-tunnel has multiple, respectively positioned at the middle part of main dustbin and sidepiece, the airintake wind-tunnel with
Angle between the bottom plate of box-like body is 60 °~90 °.
Preferably, the top plate of the filtered water tank doubles as rubbish guide plate.
