As shown in fig. 1, the conventional road pollution cleaning vehicle includes a vehicle chassis 1, a vacuum unit 3, a water tank 6 and a storage bin 2 are sequentially arranged in the horizontal direction of the vehicle chassis 1 from left to right, and since the water tank 6 is arranged between the vacuum unit 3 and the storage bin 2, an air inlet pipe is required to be arranged in the water tank 6, so that the vacuum unit 3 and the storage bin 2 can be conveniently butted. However, the air inlet pipeline occupies the space of the vehicle body, so that the volume of the road pollution cleaning vehicle is larger, the weight of the vehicle body is heavier, and the vehicle is inconvenient to turn, turn around or even cannot turn around on a street path; or the cleaning operation cannot be performed on a road which does not reach the bearing capacity.

To this end, the present embodiment relates to a road pollution cleaning vehicle, please refer to fig. 2, which includes a vehicle chassis 1, a storage bin 2, a vacuum unit 3, a cleaning device 5 and a water tank 6; the water tank 6, the vacuum unit 3 and the storage bin 2 are sequentially arranged on the vehicle chassis 1 from left to right, and the cleaning device 5 is arranged below the vehicle chassis 1; a vacuumizing device 31 is arranged in the vacuum unit 3, and the vacuumizing device 31 enables the storage bin 2 to generate negative pressure. The vehicle chassis 1 is a combination of four parts of a transmission system, a running system, a steering system and a braking system on an automobile, supports and installs an automobile engine and parts and assemblies thereof to form the integral shape of the automobile, bears the power of the engine and ensures normal running. The cleaning device 5 is used for spraying and cleaning the road surface, can loosen garbage adhered to the road surface and clean the road surface for dust fall, and can also perform vacuum suction cleaning on the road surface cleaned along with the movement of the cleaning vehicle. According to the technical scheme, the vacuum unit 3 is arranged between the water tank 6 and the storage bin 2, the storage bin 2 is directly butted with the vacuum unit 3, and the storage bin 2 generates negative pressure through the vacuumizing device 31 of the vacuum unit 3. Therefore, the space occupied by the air inlet duct 4 structure can be saved, and the weight of the whole road pollution cleaning vehicle is reduced.

Further, an air duct 4 is provided for facilitating the transportation of the air in the storage bin 2. The road pollution cleaning vehicle further comprises an air duct 4, one end of the air duct 4 is arranged on the storage bin 2, and the other end of the air duct 4 is connected with the vacuumizing device 31. One end of the air duct 4 is fixed in the storage bin 2 through a bracket, and the other end of the air duct 4 can be connected with a vacuumizing device 31 through a flange. Before the air duct 4 is not provided, an air inlet of the vacuum extractor 31 needs to be provided to be connected to the storage bin 2, as shown in fig. 2, the air inlet of the vacuum extractor 31 is provided on the front wall of the storage bin 2. After the air duct 4 is arranged, as long as it is ensured that the air inlet of the vacuumizing device 31 is connected with the air duct 4, the air duct 4 is connected with the storage bin 2 or the air duct 4 is arranged in the storage bin 2, so that the vacuumizing device 31 is connected with the storage bin 2 through the air duct 4, and the air in the storage bin 2 can be better discharged out of the atmosphere through the air duct 4 by the vacuumizing device 31.

Further, as shown in fig. 4, the vacuum extractor 31 includes a motor 32 and a fan 33, the motor 32 provides power for the fan 33, the other end of the air duct 4 is connected to the fan 33, and the fan 33 generates negative pressure in the storage bin 2. The fan 33 may be a single-stage impeller fan 33, and an air inlet of the fan 33 is disposed at the front end of the storage bin 2, so that when the fan 33 is in operation, air in the storage bin 2 can be exhausted out of the atmosphere through the air inlet of the fan 33. The fan 33 may be replaced by a vacuum pump as long as it can generate negative pressure in the storage bin 2. When the cleaning device 5 of the road pollution cleaning vehicle works, the fan 33 is started, air in the storage bin 2 is discharged into the atmosphere through the fan 33, partial vacuum is formed inside the storage bin 2, and under the action of pressure difference, sewage is carried by airflow and enters the storage bin 2 along the suction pipe. Most of the heavy objects fall into the storage bin 2 by gravity and finally the air flow is drawn into the atmosphere by the evacuation device 31.

In order to reduce the noise generated when the blower 33 is operated, the road pollution cleaning vehicle further includes a silencer connected to the vacuum extractor 31. The silencer is arranged at the air outlet of the fan 33 or the vacuum pump to reduce the working noise. Preferably, the box body of the vacuum unit 3 is also provided with noise reduction cotton made of special materials. When the cleaning device 5 of the road pollution cleaning vehicle works, the vacuumizing device 31 is started, air in the storage bin 2 is discharged into the atmosphere through the vacuumizing device 31 and the silencing device, partial vacuum is formed inside the storage bin 2, and under the action of pressure difference, sewage is carried by air flow and enters the storage bin 2 along the suction pipe. Most of the heavy objects fall into the storage bin 2 by gravity and finally the air flow enters the atmosphere through the vacuum extractor 31 and the silencer.

The gas will pass through the air duct 4 and then enter the atmosphere through the vacuum device 31 and the silencer. The mist or other particles can be carried in the gas, the air can be polluted by directly discharging the gas out of the air, and in addition, the gas is easy to corrode equipment for a long time, so that the equipment using equipment is reduced. Therefore, the road pollution cleaning vehicle further comprises a filtering device 7, and the filtering device 7 is arranged at one end of the air duct 4 close to the storage bin 2. In a preferred embodiment, the filtering device 7 is a demister. When the mist-laden gas rises through the mesh at a certain speed, the mist collides with the mesh filaments and is attached to the filament surfaces due to the inertia of the rising mist. The dispersion of the mist on the surface of the filament and the gravity sedimentation of the mist enable the mist to form larger liquid drops and flow to the junction of the two filaments along the filament. The wettability of the filament, the surface tension of the liquid and the capillary action of the filament make the droplet larger and larger until the droplet is so large that the resultant force of the rising force of the gas and the surface tension of the liquid is exceeded by the gravity generated by the droplet itself, and the droplet separates from the filament and falls. After passing through the mist eliminator, the gas is substantially free of mist. After passing through the mist eliminator, the gas is substantially free of mist. The mist in the gas is separated to improve the operation condition, optimize the process index, reduce the corrosion of the equipment, prolong the service life of the equipment, increase the treatment capacity, recover valuable materials, protect the environment and reduce the atmospheric pollution.

In other embodiments, the filtering device 7 comprises a filter screen plate and a return filter, wherein the filter screen plate is arranged in front of the return filter and is positioned at one side close to the storage bin 2. The filter screen plate is used for filtering garbage particles in the airflow. The reentry path filter is an existing device and mainly comprises a filter element and a shell. The filter element adopts a unique rotary circuitous structure and is used for filtering solid particles in water mist. When the air passes through the filter element, solid particles in the air are gathered in the groove of the filter element under the action of centrifugal force, and the solid particles are discharged from the bottom sewage discharge hole under the action of gravity. In other preferred embodiments, the filtration system may consist solely of the filter cartridge.

As a preferred embodiment, as shown in fig. 3, a baffle 22 is disposed inside the storage bin 2, one end of the baffle 22 is fixed on the top wall of the storage bin 2, and the baffle 22 is disposed at the air inlet of the air duct 4. One end of the baffle 22 is connected with the upper inner wall of the storage bin 2, and the other end of the baffle 22 can be arranged towards the lower part of the storage bin 2. When the cleaning device 5 works, pollutants enter the sewage inlet pipe 21 along with the air flow through the hose under the action of the fan 33 and finally enter the storage bin 2, the baffle plate 22 is arranged in the storage bin 2, the pollutants are blocked by the baffle plate 22 after entering the storage bin 2, the advancing direction is changed, most of the heavy objects are blocked by the baffle plate 22 and fall into the storage bin 2, other light dust materials advance along with the air flow, and the sectional area of the storage bin 2 is far larger than that of the suction pipe and the cleaning device 5, so that the speed is reduced after the air flow enters the storage bin 2, and other light materials fall into the storage bin 2 under the action of gravity. By providing the baffle 22, the majority of the material falls within the storage bin 2 and by reducing the velocity of the air flow through the baffle 22, the lighter material also falls within the storage bin 2.

A cleaning device 5 is arranged below the vehicle chassis 1, and the cleaning device 5 comprises a spray rod and a rotary joint; the rotary joint is connected with the spray rod, a first nozzle and a second nozzle are respectively arranged at two ends of the spray rod, and the first nozzle and the second nozzle are opposite in direction and are obliquely downward; the high-pressure water pump passes through rotary joint, spray lance and nozzle in proper order. When the road pollution removing vehicle carries out deep cleaning work, the cleaning device 5 is put down, the high-pressure water pump is opened, under the work of the cleaning device 5, high-pressure water passes through the rotary joint and the spray rod and is finally sprayed out from the first nozzle in a high-pressure jet flow form, and the spray rod drives the rotary joint to rotate together under the reaction force of the high-pressure water jet flow because the first nozzle and the spray rod form a certain angle, so that the high-pressure water jet flow sprayed out by the rotary spray rod assembly forms rings related to each other on the ground. When the cleaning device 5 moves on the ground at a certain speed along with the vehicle, the rings sprayed by the high-pressure water jet can be distributed in a spiral line and overlapped with each other, so that the ground can be cleaned without dead angles. Pollutants such as scale and oil stains on the ground are peeled off from the ground under the action of the striking force of the high-pressure water jet, and because the periphery of the cover body of the cleaning device 5 is sealed by the elastic baffle 22, the pollutants enter the sewage inlet pipe 21 along with the air flow through the hose under the action of the fan 33 and finally enter the storage bin 2. Because, the inside baffle 22 that is provided with of storage silo 2, the pollutant receives stopping of baffle 22 after getting into storage silo 2, changes the direction of moving ahead, and most heavy object receives the stopping of baffle 22 and falls into storage silo 2, and remaining slight dust material is along with the velocity of air current gos forward, because of storage silo 2 cross sectional area is far away than the cross sectional area of suction tube and belt cleaning device 5, so the air current gets into behind the storage silo 2, and speed reduces, and remaining slight material falls into storage silo 2 because of the action of gravity. Finally, the air flow path filtering device 7 filters solid particles in the air flow, and then the filtered air flow enters the fan 33 and the silencer through the air duct 4 and is discharged into the atmosphere.

Different from the prior art, the above technical scheme directly butt-joints the storage bin 2 with the vacuum unit 3 by arranging the vacuum unit 3 between the water tank 6 and the storage bin 2, and the storage bin 2 generates negative pressure through the vacuumizing device 31 of the vacuum unit 3. Thus, the space occupied by the air inlet duct 4 structure can be saved, and the weight of the whole road pollution cleaning vehicle is reduced.
