Description
Technical Field
The invention relates to the technical field of sweeper trucks, in particular to an air duct system of a whole sweeper truck.
Background
In order to reduce the labor intensity of sanitation workers and improve the efficiency and quality of road cleaning, it has become a trend to use sweeper to clean the road instead of old manual cleaning. In many conventional cleaning vehicles, a rotating wheel brush is provided as a cleaning device, and bristles provided on the rotating wheel brush sweep over the ground in a state of being parallel or nearly parallel to the ground during operation. When the ground is broken or deformed to cause a pit or a gap exists on the brick laying ground, the brush bristles of the rotary wheel brush parallel to the ground or nearly parallel to the ground cannot sweep dust and dirt at the pit or the gap, so that the road cleaning quality is seriously affected.

Referring to fig. 1 to 5, the air duct system of the whole sweeping vehicle of the present invention includes: the cyclone dust collector comprises a sucker 1 with a cyclone generator, an inner wall cyclone conveying pipeline 2, a spiral sedimentation dustbin 3, a centrifugal fan 4 and a cyclone separation device 5, wherein the inner wall cyclone conveying pipeline 2 is respectively connected with the sucker 1 with the cyclone generator and the spiral sedimentation dustbin 3, the centrifugal fan 4 comprises an air inlet 402 and an air outlet 403, the air inlet 402 is connected with the spiral sedimentation dustbin 3, and the air outlet 403 is connected with the cyclone separation device 5; the front end of the sucker 1 with the cyclone generator is provided with a sucker opening 103, the rear end is provided with a conveying pipeline 106, and the side wall is uniformly provided with a plurality of backflow air nozzles 104; the suction cup 1 with the cyclone generator is also provided with an air inlet 105 which can form a spiral wind field with the plurality of air return nozzles 104; the spiral sedimentation dustbin 3 is internally provided with a suction pipe 301, a guide plate 303, a middle step mesh plate 304, a filter screen 305 and an air outlet 306, the tail end of the suction pipe 301 is aligned with the inlet of the guide plate 303, and the middle step mesh plate 304 is arranged above the suction pipe 301; the filter screen 305 is connected with the middle step mesh plate 304; the air outlet 306 is disposed above the middle step mesh plate 304.
Further, the suction cup 1 with the cyclone generator further comprises a suction cup upper sealing plate 101 and a suction cup side wall 102, and the suction cup upper sealing plate 101 is arranged above the suction cup side wall 102.
Preferably, the plurality of air inlets 105 are uniformly disposed on the front section of the upper sucker sealing plate 101, and the conveying pipeline 106 is disposed on the rear section of the upper sucker sealing plate 101.
Specifically, when the whole air duct system of the motor sweeper is in a working process, the centrifugal fan 4 is electrified to run, so that negative pressure is continuously generated at the air inlet 402 to enable the internal air of the box 302 to flow to the air outlet 306, and further a negative pressure environment is formed inside the box 302. Referring back to fig. 3, at this time, the air flow of the conveying pipeline 106 moves upward from the bottom of the conveying pipeline due to the negative pressure environment formed inside the box 302, and the air flow outside the conveying pipeline continuously flows into the suction cup from the front suction cup opening 103; the return air nozzle 104 provided on the chuck sidewall 102 continuously sucks the gas around the suction cup into the chuck. Because the air return nozzle 104 is disposed on one side of the suction cup sidewall 102, and the air intake 105 is disposed above the suction cup upper seal plate 101 with respect to the air return nozzle 104; therefore, when the air flows out from the air inducing opening 105, the air is attracted by the negative pressure at the air return nozzle 104 and is guided to the inside of the sucker, and finally, the air forms a disturbance jet; the air flow flowing in from the return air nozzle 104 moves along the inner wall surface of the suction cup, and a spiral air field is formed below the air intake 105. The spiral wind field increases the trend of airflow flowing from the bottom of the air inlet 105 to the upper side thereof, thereby enhancing the trend of airflow flowing from the air inlet 105 to the return air nozzle 104, and further enhancing the trend of disturbance jet. Further, a plurality of air return nozzles 104 may be uniformly disposed on two sides of the suction cup sidewall 102, and an air inlet 105 may be disposed corresponding to each air return nozzle 104 and connected to the upper portion of the suction cup upper sealing plate 101. Specifically, the two sides of the suction cup side wall 102 may be respectively provided with the air return nozzles 104, and two air outlets 105 are respectively disposed above the suction cup upper sealing plate 101 corresponding to the two air return nozzles 104. Therefore, the garbage to be cleaned can be pushed from different angles of the periphery of the sucker and introduced into the front section sucker opening 103, and then is guided into the inner wall cyclone conveying pipeline 2 by the conveying pipeline 106. Meanwhile, in the circulating process of the air flow, the air flow around the centrifugal fan 4 is reintroduced into the sucker 1 of the to-be-cyclone generator, so that the dust emission phenomenon of the sweeper in the sweeping process is reduced. Further, the external garbage continues to enter the suction pipe 301 from the inner wall cyclone conveying pipeline 2 along the airflow, and rises from the suction pipe 301 to enter the interior of the box 302. The garbage sucked into the inside is first ejected from the end of the suction pipe 301, then the air flow carries the garbage into the inlet of the baffle 303, and then the garbage is separated along both sides of the baffle 303. At this time, a rotating flow field is formed inside the box 302, and garbage with different mass is gradually settled and separated, the garbage with larger mass is firstly settled to the bottom of the box 302, and then the garbage with smaller mass like dust continuously flows along with the gas in a rotating way. Because the centrifugal fan 2 is continuously operated to maintain the flow of the air in the interior of the case 302, the air outlet 306 is completely blocked by the two filter screens 305 and the middle stepped mesh plate 304 which are disposed side by side. That is, the middle step mesh plate 304 and the two filter screens 305 are arranged between the suction pipe 301 and the air outlet 306 side by side, so that when the rotating flow field inside the box 302 carries dust with small mass and the like to collide with the middle step mesh plate 304 and the filter screens 305, the dust and the like with the volume larger than the holes of the middle step mesh plate 304 and the filter screens 305 can be blocked by the middle step mesh plate 304 and the filter screens 305 and cannot enter the air outlet 306. However, in this process, some of the particulate garbage such as dust can pass through the middle step mesh plate 304 and the filter screen 305, and at this time, the particulate garbage of this portion will continue to follow the airflow to enter from the air inlet 402 of the centrifugal fan 4 and then leave from the air outlet 403. The air flow then carries this portion of the particulate waste into the cyclone separation device 5. The above-mentioned air flow mixes the granular garbage to form a gas-solid mixture, and the gas-solid mixture is introduced into the cyclone separation device 5 from a tangential direction, and the gas-solid mixture forms a rotating motion in the cyclone separation device 5, and the rotating motion can make solid particles or liquid drops with a large inertial centrifugal force be thrown to the inner wall surface of the cyclone separation device 5, so that the gas-solid mixture is separated from the air flow. Therefore, the granular garbage carried in the air flow can be separated and purified again after being treated by the cyclone separation device 5, so that the air duct system of the whole sweeper can discharge clean air, and the surrounding environment is prevented from being polluted.
Further, referring to fig. 6, the cyclone separation device 5 has an airflow inlet 501, a plurality of conical barrels 502, a settling box 503, and a plurality of purge outlets 504. The air inlet 501 is disposed above the conical cylinder 502, and the air inlet 501 is connected to the exhaust port 403. The settling box 503 is connected to the bottom of the conical cylinder 502, and one end of the settling box 503 is connected to the case 302. Each purge outlet 504 is disposed at the top of each conical barrel 502. Specifically, the granular garbage is mixed with the airflow to form a gas-solid mixture, and the gas-solid mixture leaves the centrifugal fan 4 from the air outlet 403 and enters the cyclone separation device 5 from the air inlet 501. The gas-solid mixture is divided into several parts, each part of the gas-solid mixture enters tangentially from the upper part of each conical cylinder 502, at the moment, the gas-solid mixture changes from linear motion to circular motion, and most of the rotating airflow can flow downwards spirally from the cylinder towards the bottom of the conical cylinder along the inner wall of the conical cylinder; at this time, the particles in the gas-solid mixture are thrown against the inner wall of the conical cylinder 502 by centrifugal force, and the particles lose their inertial force immediately after contacting with the inner wall, and then the particles fall down along the inner wall surface along the momentum of the downward axial velocity near the collision point, and then fall into the settling box 503, and then they can also enter the inside of the case 302 from the settling box 503. In addition, the descending outer gas stream of the gas-solid mixture continuously flows into the central portion of the cone 502 during its descent, thereby creating a centripetal radial gas stream that constitutes the upward rotating inner stream. The rotation directions of the internal rotation and the external rotation are the same. Accordingly, the finally purified air can be discharged to the outside environment from the purification outlets 504 correspondingly provided at the top of the conical cylinder 502.
Further, a top cover 307 is further provided on the top of the box 302, the top cover 307 is rotatably connected with the box 302, and the deflector 303 is connected below the top cover 307. Specifically, a side edge of the top cover 307 may be turned to open and close along the top of the box 302, so that a user may open the top cover 307 to dump dust and other garbage collected inside the box 302.
In particular, two hydraulic rods 308 are connected to one side of the top cover 307, and the hydraulic rods 308 are beneficial to increase the damping of the top cover 307 when being opened, so as to facilitate the operation of a user.
Further, a suction cup door 107 is further disposed in front of the suction cup upper sealing plate 101, and the suction cup door 107 is movably connected with the suction cup upper sealing plate 101. Specifically, the suction cup door 107 may rotate along its connection with the suction cup upper sealing plate 101 and close the front suction cup opening 103.
Preferably, the return air nozzle 104 and the air guiding opening 105 may be configured in a circular tube shape, and the circular tube-shaped return air nozzle 104 and the circular tube-shaped air guiding opening 105 are beneficial to circulating air flow and form a spiral air field at the bottom of the air guiding opening 105.
Furthermore, the centrifugal fan 4 can be replaced by a common fan, and the common fan can also realize the working effect of the whole air duct system of the sweeper.
In summary, the whole air duct system of the sweeper is provided with the sucker 1 with the cyclone generator, the inner wall cyclone conveying pipeline 2, the spiral sedimentation dustbin 3, the centrifugal fan 4 and the cyclone separation device 5. The suction cup 1 with the cyclone generator is generally arranged parallel or approximately parallel to the bottom surface to be cleaned, and the inner wall cyclone conveying pipeline 2 is respectively connected with the suction cup 1 with the cyclone generator and the spiral sedimentation dustbin 3. Each return air nozzle 104 and each air inducing opening 105 arranged on the cyclone generator can be mutually matched in the sucker to form a spiral air field, the spiral air field can increase the trend of airflow flowing along the air inducing opening 105, and meanwhile, the trend of the return air nozzles 104 for attracting peripheral airflow into the sucker can also be increased, so that the whole air duct system of the sweeper can push garbage to be cleaned from different angles around the air duct system of the sweeper, and the garbage to be cleaned is attracted into the conveying pipeline 106. In addition, the air flow around the centrifugal fan 4 can be reintroduced into the sucker with the cyclone generator through the air return nozzle 104, so that the repeated circulation of the air flow is realized, the phenomenon that dust is discharged by the sweeper in the sweeping process is reduced, and the condition of secondary environmental pollution when the sweeper is cleaned is effectively reduced. In addition, the centrifugal fan 4 is disposed at the front side of the spiral settling dustbin 3, and the cyclone 5 is disposed at the side of the centrifugal fan 4. The spiral sedimentation dustbin 3 makes the garbage sucked by the suction cup 1 with the cyclone generator enter the inside of the dustbin 302 through the suction pipe 301, wherein most of the sucked garbage is settled at the bottom of the dustbin 302 step by step after a plurality of spiral movements are carried out in the dustbin 302, and the non-settled part of the garbage is blocked again by the middle step mesh plate 304 and the filter screen 305, the rest of the finer granular garbage can enter the centrifugal fan 4 from the air inlet 402 along with the air flow, and then the air-solid mixture composed of the air flow and the granular garbage is transported into the cyclone separation device 5 from the centrifugal fan 4. The gas-solid mixture enters from the tangential direction of the conical cylinder 502 and forms a spiral motion therein, and the solid particles in the gas-solid mixture lose inertia force after hitting the inner wall of the conical cylinder 502 and settle into the settling box 503. Therefore, after the multistage separation, the air duct system of the whole motor sweeper can discharge clean air flow, so that the environmental pollution of the periphery in the working process is avoided. Therefore, the whole air duct system of the sweeper generates a spiral flow field in the sucking and sweeping process by introducing the sucking disc 1 with the cyclone generator, so that the working efficiency of the sweeper is improved; meanwhile, the sucker 1 with the cyclone generator can introduce the air flow around the centrifugal fan 4 into the internal circulation of the sucker, so that the secondary dust raising condition of the sweeper during working is greatly reduced. In addition, the tangential nozzles are added to the inner wall cyclone conveying pipeline 2, so that garbage forms cyclone in the inner wall cyclone conveying pipeline, and the possibility that the inner wall cyclone conveying pipeline 2 is blocked is reduced. And moreover, the spiral sedimentation dustbin 3, the centrifugal fan 4 and the cyclone separation device 5 are mutually matched, so that the dust content in the exhaust of the sweeper is effectively reduced, and the pollution of the dust in the exhaust to the environment is avoided.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
