Description
Technical Field
The invention relates to the technical field of sanitation trucks, in particular to a sanitation truck and a dust falling structure thereof.
Background
In sanitation car products, especially road sweeper, dust raising is serious during operation, the current adopted spray dust fall is difficult to control, and a large amount of dust is still injected into the air. Particularly, in an area with serious ground dust accumulation, once the sweeping machine is started to operate, the operation vehicle is instantly shielded by raised dust, so that the environment is seriously polluted or the sweeping machine cannot operate. At present, the spraying dust-settling measures of the sweeping machine mainly comprise the following two parts, wherein the first part is to spray at the sweeping brush of the sweeping machine to perform dust suppression control on the sweeping brush; secondly, an atomizing nozzle is arranged in the inner cavity of the suction pipe to spray water for dust reduction. If the water yield is too little, the dust suppression effect can't be reached in simple spraying dust fall, if increase the water yield, will need the very big water tank of design volume, must compress the volumetric space of other annex such as dustbin to limited on-vehicle space like this. And for the road section with serious dust deposition, the dust suppression effect is difficult to achieve by spraying and dust falling.
The existing market has a dust collection vehicle and a dust-free dry sweeping vehicle which adopt filter elements for dust removal, the road sweeping operation equipment with the filter elements does not need to arrange a large number of large-volume filter elements, the capacity of a dustbin is a little smaller than that of a spraying dust-reduction sweeping vehicle, and a specific operation road section is a pure dry road surface, so that once the dust collection vehicle hits the accumulated water or the wet road surface, the filter elements are irreversibly damaged.
For the sweeping machine for spraying and dust settling, the space of a dustbin and other accessories is inevitably compressed on the basis of the limited vehicle-mounted volume, and the effective volume of the dustbin is reduced after the volume of the dustbin is compressed, so that the sweeping machine is unfavorable; in addition, the road sweeper needs to be filled with a tank of water when going out for operation, and for a pure electric road sweeper, the increase of load can lead to the increase of power consumption, and the operation endurance mileage of the road sweeper is reduced.
Similarly, for dust collection vehicles and dust-free dry sweeping vehicles, the effective volume of the dustbin is also compressed due to the need of additionally arranging the filter cartridge, and the added filter cartridge increases the servicing quality and reduces the endurance mileage of the battery. In addition, the sweeping vehicle with the filter cartridge cannot work on wet pavements and water accumulation pavements, and the filter element cannot be cleaned once being stained with silt, so that the filter element is damaged; and owing to increased the filter core, in order to reach better filtering effect, the pressure loss that the air current passes through reaches more than 1KPa, has increased the centrifugal fan load of sweeping machine, the cleaning operation ability that reduces.
Therefore, how to realize effective dust removal of the sanitation vehicle is a problem to be solved urgently by technical personnel in the field at present.
