Description

The automobile-used dust exhaust apparatus of road-cleaning
Technical field
The utility model relates to a kind of dust exhaust apparatus, relates in particular to a kind of dust exhaust apparatus that is exclusively used in road sweeper.
Background technology
At present, domestic road sweeper commonly used has rotating disc type road-sweeper, rolling disc type road-sweeper and gold to blot formula air-flow vacuum sweeper, the following shortcoming of these device ubiquities:
1, fan life is short partially.Blower fan in the automobile-used dust exhaust apparatus of existing road-cleaning is positioned at the mid portion of breezeway mostly, although before the import of blower fan, taked some separating measure, but still can't effectively avoid the graininess dust through blower fan inside, so just must increase fan blade and inner wearing and tearing, reduce fan efficiency and application life greatly.
2, the reentrainment of dust problem is difficult to solve.Obviously, just have the airborne dust generation as long as carry out brush work.Settle the matter once and for all, just must adjust relation between ground pressure, working speed and the spray flow of brush, and other relative measures according to ground refuse kind and dust concentration, but apparent this difficulty relatively.Even present dust-absorption sweeping type sweeping machine on the market, at dust for a long time, reentrainment of dust is still serious mostly, is difficult to fundamentally eliminate, and particularly in the bigger area of northern dust storm, this phenomenon is more outstanding.
3, the road-sweeper uninterrupted working time is shorter.Just because the existence of airborne dust problem, the cleaning process dust suppression of need sprinkling water, so, the dust-absorption sweeping type sweeping machine except more than the dust pelletizing system cover retaining mechanism, comprise water tank, discharging valve, water filling port, water pump, shower nozzle, electromagnetic valve etc., so just when increasing manufacturing cost, also strengthened fault rate; Simultaneously, the size of water tank is the length of decision road-sweeper uninterrupted working time directly: water tank is excessive, removes and takies the car load space, increases the body structure complexity, also reduces the space in rubbish sedimentation storehouse relatively, influences effect of settling and refuse collection amount; Water tank is too small, and continuous midway waterside number increases, and reduces operating efficiency.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, efficiency of dust collection is high, the automobile-used dust exhaust apparatus of the road-cleaning of blower fan long service life.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The automobile-used dust exhaust apparatus of a kind of road-cleaning, comprise dust shield, blower fan, sack cleaner, air draught road and breezeway, wherein an end in air draught road communicates with the inlet scoop of dust shield, one end of breezeway links to each other with the blowing mouth of dust shield, the other end links to each other with the outlet of sack cleaner, blower fan is located in the breezeway, the automobile-used dust exhaust apparatus of this road-cleaning also comprises gravitational precipitator, the other end in air draught road links to each other with the inlet of gravitational precipitator, the outlet of gravitational precipitator links to each other with the inlet of sack cleaner by intermediate conduit, is equipped with unloading valve in the bottom of sack cleaner and gravitational precipitator.
Top at sack cleaner is provided with cloth envelop collector and vibrator from bottom to top successively.
The cross section of described dust shield is trapezoidal, and the space that the blowing mouth of feasible dust shield in use and ground form is less than the space of inlet scoop and ground formation.
Being provided with rubber strip in the bottom of dust shield is flexible coupling with formation.
Compared with prior art, the utility model technology has the following advantages:
1, the utility model is simple in structure, efficiency of dust collection is high, the blower fan long service life.The utility model is by having set up gravitational precipitator between dust shield and sack cleaner, therefore, graininess dust on the ground in the dust is just at first absorbed by gravitational precipitator, be deposited on the bottom of gravitational precipitator, dust after gravitational precipitator is handled just enters sack cleaner and carries out secondary and absorb and handle then, so just form the working method of twice filtration, fractional precipitation, improved efficiency of dust collection; Simultaneously, because the graininess dust is absorbed by gravitational precipitator, because of entering fan blade and the inner wearing and tearing that cause in the blower fan, the graininess dust prolonged the application life of blower fan with regard to effectively having avoided like this.
2, the utility model can effectively be avoided reentrainment of dust.In the utility model, by bottom rubber strip is set and has formed being flexible coupling between dust shield and the ground at dust shield, strengthened the sealing effectiveness of dust shield like this, the utility model is trapezoidal dust shield by adopting the cross section simultaneously, the space that the blowing mouth of feasible dust shield in use and ground form is less than the space of inlet scoop and ground formation, making the object that blows afloat have time enough to focus on the inlet scoop is so all siphoned away, by carrying out the improvement of above-mentioned two measures, strengthened the pick-up performance of dust shield, effectively avoided the reentrainment of dust problem, therefore, when using the utility model, road sweeper just do not need to dispose in addition water-storing device, therefore saved investment, reduced running cost, reduce maintenance cost, and prolonged the uninterrupted working time of road-sweeper.
3, the utility model is convenient to focusing on of dust.Owing to be equipped with unloading valve in the bottom of sack cleaner and gravitational precipitator, simultaneously be provided with vibrator and cloth envelop collector on sack cleaner top, like this under the vibration of the vibrator at cloth envelop collector top, dust splits away off bottom at cloth envelop collector from the filter bag of cloth envelop collector, like this, when detecting two dusts in the deduster, open unloading valve to predetermined height, just the dust in the two can be focused on, saved the processing time of dust.
