Description

Technical Field

[0001] This utility model relates to the field of sweeper technology, specifically to a water-circulating filter self-unloading sweeper. Background Technology

[0002] Currently, dust filtration in sweepers mainly uses dry and wet filtration systems. Dry filtration systems are prone to clogging by dust and malfunction. Wet filtration requires a large amount of water, leading to excessive water accumulation in the garbage collection bin and wastewater overflowing during subsequent garbage transfer. Insufficient water spray results in incomplete dust filtration and severe dust generation during sweeping operations. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is:

[0004] I. A water-circulating filter self-unloading sweeper is provided, which reduces dust through a zoned filtration method.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-circulating filter self-unloading sweeper, comprising a vehicle body, a sweeping assembly, and a waste collection assembly. The sweeping assembly includes a sweeping brush and a suction pipe. The waste collection assembly includes a waste collection bin, a suction fan, and a centrifugal separator. The sweeping brush and the suction pipe are both mounted on the vehicle body. One end of the suction pipe is a suction cup, positioned corresponding to the ground surface. The waste collection bin includes a spray dust removal area and a waste collection area. The other end of the suction pipe is connected to the waste collection area. The waste collection area and the spray dust removal area are separated by a filter screen. The centrifugal separator is connected to the spray dust removal area. The suction fan is positioned between the centrifugal separator and the spray dust removal area. The waste collection bin is rotatably connected to the vehicle body. The vehicle body is also equipped with a telescopic push rod for driving the waste collection bin to rotate. The waste collection area of ​​the waste collection bin is provided with an openable and closable waste unloading port.

[0006] The vacuum cleaner fan draws air from the spray dust removal area, lowering the air pressure compared to the garbage collection area and the suction pipe. Suction is generated at the suction cups in the suction pipe, drawing garbage and dust into the garbage collection area. Lighter, larger pieces of garbage are caught by the filter and fall to the bottom of the garbage collection area. Smaller dust particles are drawn into the spray dust removal area and combine with the water mist there to form a mixed gas, which is then guided by the vacuum cleaner fan to a centrifugal separator for water-air separation. The separated clean air is discharged through the exhaust vent in the centrifugal separator, while the separated wastewater is discharged through the drain vent. After cleaning is complete, the garbage unloading mechanism is opened. The loading port and telescopic push rod drive the garbage collection bin to lift, causing the garbage in the garbage collection area to be dumped out of the garbage unloading port due to gravity.

[0007] Optionally, the centrifuge is connected to a drain pipe, one end of which is connected to the centrifuge, and the outlet of the other end of the drain pipe is located in front of the suction cup.

[0008] The drain pipe collects the wastewater separated from the drain outlet. The drain pipe guides the wastewater to the suction cup, where it is immediately sucked into the waste collection area. As the wastewater passes through the suction pipe, it mixes with the waste and dust inside, achieving a certain dust removal effect.

[0009] Optionally, a first extension pipe is also provided in the garbage collection area, and the first extension pipe is connected to the vacuum pipe.

[0010] When the garbage collection bin adopts a design that allows it to be lifted as a whole, it will inevitably have an opening connected to the suction pipe. The main function of the first extension pipe is to prevent dirt remaining in the garbage collection bin from flowing out through the opening when the bin is lifted. Especially in this design, the opening is located in the spray dust removal area, where dirt is prone to accumulate on its inner wall.

[0011] Optionally, the connection between the spray dust removal area and the dust extraction fan is an air outlet, and a cover plate is rotatably connected to the air outlet. A protrusion is provided on the dust extraction fan at a position corresponding to the air outlet, and the protrusion corresponds to the position of the cover plate.

[0012] Both the vacuum cleaner fan and the centrifugal separator are fixedly mounted on the vehicle body. The garbage collection bin separates from the inlet of the vacuum cleaner fan when it is raised, so a cover is designed at the air outlet. This cover automatically closes when the garbage collection bin is raised and is pushed open by a protrusion when the garbage collection bin is lowered, allowing the vacuum cleaner fan to connect with the garbage collection bin.

[0013] Optionally, a first sealing ring is also provided between the first extension tube and the suction tube. Optionally, a second sealing ring is also provided at the air outlet of the waste collection bin.

[0014] Both the first and second sealing rings are designed to ensure the airtightness of the space between the inside of the trash can and the suction pipe and vacuum fan when the trash can is lowered, preventing dirt from overflowing from the gaps between the trash can and the suction pipe, and between the trash can and the vacuum fan.

[0015] The beneficial technical effects of this utility model are: it uses a dust extraction fan to provide air circulation power, combined with spray dust removal, filters, and centrifugal separators to classify garbage, reduce dust, and recycle wastewater. Furthermore, a special design for the sewage pipe enables the secondary utilization of wastewater. Attached Figure Description

It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] Reference Figure 1-3 As shown, a water-circulating filter self-unloading sweeper includes a vehicle body 1, a sweeping assembly, and a waste collection assembly. The arrows in the figure indicate the flow paths of waste or gas.

[0020] The cleaning assembly includes a sweeping brush 2 and a suction pipe 3. Both the sweeping brush 2 and the suction pipe 3 are mounted on the vehicle body 1. One end of the suction pipe 3 is a suction cup 9, and the position of the suction cup 9 corresponds to the ground surface.

[0021] The waste recycling assembly includes a waste collection bin, a vacuum blower 4, and a centrifugal separator 18. The waste collection bin includes a spray dust removal zone 5 and a waste collection zone 6. The other end of the vacuum pipe 3 is connected to the waste collection zone 6. The waste collection zone 6 and the spray dust removal zone are separated by a filter screen 7. The centrifugal separator 18 is connected to the spray dust removal zone. The vacuum blower 4 is located between the centrifugal separator 18 and the spray dust removal zone. A drain pipe 8 is connected to the centrifugal separator 18. One end of the drain pipe 8 is connected to the centrifugal separator 18, and the outlet of the other end of the drain pipe 8 is located in front of the suction cup 9.

[0022] The garbage collection bin is rotatably connected to the vehicle body 1 at the garbage bin's movable fulcrum 17. The vehicle body 1 is equipped with a telescopic push rod 10 that drives the garbage collection bin to rotate. The garbage collection area 6 of the garbage collection bin is equipped with an openable and closable garbage unloading port 11. The telescopic push rod 10 is hydraulically driven. A first extension pipe 19 is also provided in the garbage collection area 6, and the first extension pipe 19 is connected to the vacuum pipe 3.

[0023] The connection between the spray dust removal area and the vacuum fan 4 is the air outlet 20. A cover plate 12 is rotatably connected to the air outlet 20. A protrusion 13 is provided on the vacuum fan 4 at the position corresponding to the air outlet 20. The protrusion 13 corresponds to the position of the cover plate 12.

[0024] A first sealing ring 14 is also provided between the first extension pipe 19 and the suction pipe 3. A second sealing ring 15 is also provided at the air outlet 20 of the garbage collection bin.

[0025] The vacuum cleaner 4 draws air from the spray dust removal area, reducing its air pressure to lower than that of the garbage collection area 6 and the suction pipe 3. Suction is generated at the suction cup 9 of the suction pipe 3, drawing garbage and dust into the garbage collection area 6. Lighter and larger garbage is caught by the filter screen 7 and falls to the bottom of the garbage collection area 6. Smaller dust particles are drawn into the spray dust removal area and combine with the water mist there to form a mixed gas, which is then guided by the vacuum cleaner 4 to the centrifugal separator 18 for water-air separation. The separated clean air is discharged through the exhaust port 16 in the centrifugal separator, and the separated wastewater is discharged through the drain port in the centrifugal separator. After cleaning, the garbage unloading port 11 is opened, and the telescopic push rod 10 drives the garbage collection box to lift, causing the garbage in the garbage collection area 6 to be dumped out of the garbage unloading port 11 under gravity.

[0026] The sewage pipe 8 is used to collect the sewage separated from the sewage outlet. The sewage pipe 8 guides the sewage to the suction cup 9, and the sewage entering the suction cup 9 is immediately sucked into the garbage collection area 6. When the sewage passes through the suction pipe 3, it mixes with the garbage and dust in the suction pipe 3, which has a certain dust removal effect.

[0027] When the garbage collection bin adopts a design that allows it to be lifted as a whole, it will inevitably have an opening connected to the suction pipe 3. The main function of the first extension pipe 19 is to prevent dirt remaining in the garbage collection bin from flowing out through the opening when the bin is lifted. Especially in this design, the opening is located in the spray dust removal area, where dirt is easily absorbed onto its inner wall.

[0028] Both the vacuum cleaner fan 4 and the centrifugal separator 18 are fixedly mounted on the vehicle body 1. The garbage collection bin separates from the inlet of the vacuum cleaner fan 4 when it is lifted, so a cover plate 12 is designed at the air outlet 20. This allows the cover plate 12 to close automatically when the garbage collection bin is lifted and to be opened by the protrusion 13 when the garbage collection bin is lowered, so as to connect the vacuum cleaner fan 4 and the garbage collection bin without affecting the airflow speed generated by the vacuum cleaner fan as much as possible.

[0029] Both the first sealing ring 14 and the second sealing ring 15 are designed to ensure the airtightness of the space between the inside of the garbage collection bin and the vacuum pipe 3 and the vacuum fan 4 when the garbage collection bin is lowered, so as to prevent dirt from overflowing from the gaps between the garbage collection bin and the vacuum pipe 3 and between the garbage collection bin and the vacuum fan 4.
