Description
Technical Field
The invention relates to the field of mobile cleaning equipment, in particular to a cleaning vehicle.
Background
The conventional movable dust removing equipment often causes the blockage of the filtering equipment in the dust removing equipment after being used for a period of time, and the filtering material needs to be cleaned or replaced regularly to ensure that the dust removing equipment can effectively operate for a long time. The cleaning vehicle in the mobile dust removing device can absorb dust on the cleaned road surface after the road surface is cleaned for a period of time, so that the filter cylinder in the cleaning vehicle is blocked, the filter cylinder needs to be cleaned regularly, and even the filter cylinder needs to be replaced. The existing sweeper adopts the direct suction type dust removal principle, the dust removal device adopts a filter cartridge, as shown in fig. 1, the external structure of the filter cartridge 400 is a polygonal pleat structure 410, the gas before filtration passes through the polygonal pleat structure 410 and enters the filter cartridge 400 (the direction of arrow direction is seen in the gas flowing direction), and the gas is filtered through the polygonal pleat structure 410, so that dust removal is realized. However, after long-term use, a large amount of dust is often accumulated outside the polygonal pleated structure 410, and regular cleaning is required, and the conventional cleaning method adopts a regular back-blowing method, as shown in fig. 2, an air valve 500, an air tank 600 and an air pump 700 are often additionally provided on the sweeper, which are sequentially connected, the air outlet end of the air valve 500 is connected with the air outlet end of the filter cartridge 400, and when cleaning is required, the air valve 500 is opened, and high-pressure pulse air is filled inside the filter cartridge 400, so that the accumulated dust outside the polygonal pleated structure 410 is blown off. However, in the actual use process, the soot blowing method for the filter cartridge has many problems, such as incomplete soot blowing, short service life of the filter cartridge, and the like, which will be described below.
Since adjacent pleat blades 411 in the outer polygonal pleat structure 410 of the filter cartridge 400 form an acute angle structure 412 with a smaller angle, dust often accumulates at the acute angle structure 412, and moisture is often inevitably sucked during cleaning, at this time, the fine moisture will fix the dust at the acute angle structure 412 on the polygonal pleat structure 410, and pulse gas with high pressure is difficult to blow down, causing long-term blockage, so that the filtration efficiency of the filter cartridge 400 is reduced, on one hand, the suction power is increased, and on the other hand, the dust removal efficiency is reduced. In addition, the arrangement of the filter cartridge 400 also causes the failure of the soot blowing part, as shown in fig. 3 and 4, the arrangement of the filter cartridge 400 in the motor sweeper can be horizontal, as shown in fig. 3, or vertical, as shown in fig. 4, when the filter cartridge 400 is horizontally arranged, the pulse gas of back blowing enters the filter cartridge 400 from one end of the filter cartridge 400 due to the longer length, the part of the filter cartridge 400 away from the air inlet end of the pulse gas of back blowing receives weaker aerodynamic force, and the soot blowing efficiency is reduced; on the other hand, as shown in fig. 1, when the horizontally arranged filter cartridge 400 performs soot blowing, dust located in the lower half 420 of the filter cartridge is separated from the polygonal pleat structure 410 under the action of the pulse gas, but after the dust located in the upper half 430 of the filter cartridge is separated from the polygonal pleat structure 410 under the action of the pulse gas, the dust is reattached to the polygonal pleat structure 410 under the action of gravity, so that the soot blowing fails, and as a result, the filtering efficiency of the filter cartridge is generally reduced, and as a result, the soot deposition attaching effect attached to the filter cartridge 400 is improved, and finally, the dust is difficult to separate from the filter cartridge, so that the filter cartridge 400 fails and needs to be replaced.
Moreover, when the sweeper runs on the road surface, the sweeper always inevitably passes through the accumulated water road surface, at this time, water on the ground is contacted with the surface of the filter cartridge 400 to infiltrate the filter cartridge 400, the meshes of the filter cartridge 400 are blocked after the water is mixed with dust on the surface of the filter cartridge 400, and the filter cartridge is difficult to clean by using pulse gas, so that the filter cartridge is invalid and is scrapped, and the use cost is high; in order to solve the problem, in the prior art, a design of switching the air sucked by the suction cup is adopted, when the air enters the water-bearing ground, the sucked air is directly discharged from the fan, the air sucked from the dry ground is filtered through the filter cartridge, the switching is performed through manual observation operation, the requirement on an operator is high, when the operator does not switch on the wet ground, the filter cartridge 400 is scrapped when the operator is in water feeding, and conversely, if the air is erroneously switched on the dry ground, the air containing a large amount of dust sucked from the ground is discharged into the surrounding environment at high pressure after passing through the fan, and dust is caused.
