Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sanitation equipment, and in particular to a dust removal and haze reduction cleaning vehicle with a circulating air inlet guide device. Background Art
[0002] The cleaning vehicle is a common sanitation vehicle for road cleaning. It uses the negative pressure generated by the fan to form a strong airflow through the dust collection system. The dust and particles on the ground are sucked into the cleaning vehicle under the action of the airflow. These dust and particles move with the airflow in the pipeline. The larger and heavier particles will settle in the negative pressure cabin and enter the garbage bin of the cleaning vehicle, while the lighter dust will enter the filter device with the air.
[0003] However, traditional cleaning vehicles use fans to directly introduce the air in the negative pressure cabin into the filter device, causing the filter device to directly bear the high wind pressure discharged by the negative pressure fan. This high-intensity wind pressure impact not only greatly shortens the service life of the filter device and increases the maintenance cost of the equipment, but also because of the uneven distribution of wind pressure, the filter area that is directly blown is subjected to excessive pressure and is easily damaged, while the filter area that is not directly blown cannot effectively perform its filtering function due to the lack of sufficient airflow. At the same time, since the fan of the dust collection and filtration system directly blows air to the filter device, it will generate a lot of noise, which not only poses a potential threat to the hearing health of the operator, but also may cause unnecessary noise pollution to the surrounding environment. Summary of the invention

They do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the scope of protection of the present application.
[0019] refer to Figures 1 to 3As shown, this embodiment discloses a dust removal and haze reduction cleaning vehicle with a circulating air inlet guiding device, comprising a chassis 1, and a dust collecting device 2, a garbage collecting device 3 and a dust collecting device 4 fixed on the chassis 1; The dust collecting device 2 includes a suction port assembly 21, a negative pressure cabin 22 and a fan 23. The suction port assembly 21 is connected to the negative pressure cabin 22 through a feed hose 24, and the fan 23 is fixed on the top of the negative pressure cabin 22. The garbage collection device 3 is connected to the bottom of the negative pressure cabin 22; The dust collecting device 4 includes a dust compartment 42 and a filtering device 41 connected to the top of the dust compartment 42. A circulating air guide device 421 connected to the fan 23 is provided on the top of the dust compartment 42, which is used to introduce dust-laden air from the fan 23 into the bottom of the dust compartment 42, and then blow it back upward from the bottom of the dust compartment 42 to the filtering device 41.
[0020] In the cleaning vehicle of this embodiment, the air containing dust outputted from the fan 23 first reaches the bottom of the dust chamber 42 through the circulating air inlet guide device 421, and then is blown upward to the filter device 41 under the reflection effect of the bottom plate of the dust chamber 42, so that the air containing dust can evenly contact the filter device 41. Thus, the filtering function of the filter device 41 is fully utilized, and the filtering effect is enhanced; and the filter device 41 is prevented from directly bearing the high-power wind pressure directly discharged by the fan 23, which not only reduces the noise, but also increases the service life of the filter device 41.
[0021] Specifically, the suction port assembly 21 is arranged below the chassis 1, and its left and right ends are connected to the chassis 1 through telescopic components. The telescopic component includes an electric push rod and a chain, wherein the electric push rod is fixed to the chassis 1 through bolts and a clamping ring, the output end of the electric push rod is fixedly connected to one end of the chain, and the other end of the chain is fixedly connected to the suction port assembly 21. During operation, the output end of the electric push rod extends downward, lowering the suction port assembly 21 to contact the ground, and under the action of the fan 23, a negative pressure area is formed around the suction port assembly 21, and dust and particulate matter on the ground are sucked into the suction port assembly 21. After the work is completed, the output end of the electric push rod retracts upward, and the suction port assembly 21 is raised to a predetermined height, thereby improving the passability of the vehicle.
[0022] Secondly, the negative pressure cabin 22 is a box-shaped structure in an inverted trapezoidal shape, with a feed port connected to the feed hose 24 on its inclined surface, a garbage outlet connected to the garbage collection device 3 at the bottom, and a dust outlet connected to the dust collection device 4 at the top. A guide plate 221 extending from the feed port to above the garbage outlet is provided in the negative pressure cabin 22, and the end of the guide plate 221 is a downwardly curved arc structure for introducing large particles in the dust into the garbage collection device 3. Through the guiding effect of the guide plate 221, larger and heavier particles are settled in the negative pressure cabin 22 and enter the garbage collection device 3 of the cleaning vehicle, thereby enhancing the garbage classification function of the vacuum system and reducing the filtering pressure of the filtering system.
[0023] refer to Figure 4 , Figure 6 As shown, a strip brush assembly 223 and a filter 222 are also provided in the negative pressure cabin 22. Preferably, the strip brush assembly 223 and the filter 222 are made of aluminum alloy to enhance their rigidity and wear resistance and increase their service life. The filter 222 is fixed at the dust outlet by a fastener to filter the particles escaping from the guide plate 221. The strip brush assembly 223 is fixed below the filter 222, the top of the strip brush assembly 223 abuts against the bottom of the filter 222, and the two ends of the strip brush assembly 223 are slidably connected to the negative pressure cabin 22 through a guide rail, wherein the strip brush assembly 223 is also connected to a driving device for driving it to move, preferably, the driving device is an electric push rod. The driving device can brush off the particles adsorbed on the filter 222 when driving the strip brush assembly 223 to slide. Avoid particles from clogging the filter 222 to ensure the unobstructed dust outlet of the negative pressure cabin 22.
[0024] In some embodiments, the fan 23 is fixed above the negative pressure cabin 22 via a fan bracket 25 , and an air inlet of the fan 23 is sealedly connected to a dust outlet of the negative pressure cabin 22 via a sealing gasket 224 .
[0025] In some embodiments, reference Figure 3 , Figure 5As shown, the dust chamber 42 is a V-shaped structure, and the circulating flow guiding air inlet device 421 is a hollow arc-shaped cylindrical structure, the upper end opening of which is sealed and connected to the air outlet of the fan 23, and the lower end opening is connected to the dust chamber 42, and the caliber of the circulating flow guiding air inlet device 421 gradually expands and increases from top to bottom. The air with dust reaches the dust chamber 42 through the circulating flow guiding air inlet device 421, and then blows back upward to the filter device 41 under the reflection effect of the V-shaped bottom plate of the dust chamber 42, so that the air with dust can evenly contact the filter device 41. The circulating flow guiding air inlet device 421 of this embodiment adopts an arc design, which helps to reduce the turbulence and eddy current of the air flow in the channel, making the air flow more stable and uniform. At the same time, the caliber of the circulating flow guiding air inlet device 421 gradually expands and increases from top to bottom, which can increase the air intake area and reduce the air flow speed entering the dust chamber 42, thereby increasing the uniformity of the air flow distribution in the dust chamber 42, increasing the contact area between the air flow and the filter device 41, and improving the dust filtering effect.
[0026] Furthermore, the circulating flow guiding air inlet device 421 is provided with a plurality of partitions arranged at intervals along the radial direction thereof, wherein the partition is an arc-shaped plate with the same curvature as the circulating flow guiding air inlet device 421, and the left and right sides of the partition are fixed on the inner wall of the circulating flow guiding air inlet device 421. The partition divides the circulating flow guiding air inlet device 421 into a plurality of evenly spaced feed channels. The plurality of feed channels makes the airflow more evenly distributed in the dust chamber 42, further improving the dust collection efficiency.
[0027] In some embodiments, the filter device 41 includes cloth bags disposed on both sides of the circulating air inlet device 421, and the cloth bags are folded in a serpentine structure and extend along the length direction of the dust compartment 42. When the dusty air passes through the cloth bags, the dust therein will be adsorbed on the cloth bags, and the clean air will be discharged to the external environment through the cloth bags. The filter device 41 also includes a vibration component, which is used to shake the dust adsorbed on the cloth bags after the cleaning vehicle finishes working. The dust compartment 42 is a V-shaped structure, and a discharge port 423 is provided on one side of its bottom. The bottom of the dust compartment 42 is also provided with an auger assembly 422 extending along its length direction and rotatably connected thereto. When the auger assembly 422 rotates, the dust at the bottom of the dust compartment 42 is driven to be discharged from the discharge port 423.
[0028] In some embodiments, the garbage collection device 3 includes a garbage bin 31 and a lifting device 32 for supporting and driving the garbage bin 31 to rise and fall. The lifting device 32 is fixed on the chassis 1. The lifting device 32 drives the garbage bin 31 to rise to a predetermined position and then is sealed and connected to the negative pressure cabin 22. After the lifting device 32 drives the garbage bin 31 to descend to the predetermined position, the operator can take out the garbage bin 31 to facilitate cleaning of the garbage therein.

Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present application.
