Problems solved by technology

The reason for the comparison is that the cleaning and sweeping vehicles have different filtering conditions. Generally, the time required for the vehicle to filter while working is short (the vibration is severe and the sewage lacks a "sedimentation" process), the filtering space is narrow and limited, and the filtering terminal (filter rod, etc.) lasts for a long time. Soaked in turbid sewage, etc.
[0005] In addition, the existing sewage circulation device for cleaning and sweeping vehicles uses a sewage pump to suck the filtered clean water to the clean water tank. In order to avoid the suction effect being affected by the air entering the suction pump, the filter terminal needs to be completely soaked in ( Sewage) water, so the capacity of filtered sewage is also limited (the time allowed for filtration is also shortened during continuous operation)
Therefore, the "built-in" filter device technically has the defects of high initial filtration point, less sewage available for filtration, and short filtration time requirements (large filtration flow requirements).

Abstract

The invention relates to a sewage circulating device of a washing and cleaning vehicle. The sewage circulating device of a washing and cleaning vehicle includes a clean water tank, a trash can, a first-stage solid-liquid separation mechanism and a second-stage solid-liquid separation mechanism. The clean water tank, the trash can and the filter can are detachably mounted on the vehicle chassis ofthe washing and cleaning vehicle, and a garbage bin is separated into a dirt suction bin and a treatment bin by a first partition plate, a first-stage solid-liquid separating mechanism is detachably installed on the inside of a rear door provided at the rear end of the garbage can; a primary solid-liquid separation mechanism comprises the upper filter screen and a lower filter screen, the upper filter screen, a lower filter screen and an inner side wall of a rear door are enclosed to form a filter screen bin, a mesh filter bin is communicated with that dirt suction bin through the upper mesh filter, a secondary solid-liquid separation mechanism can be detachably installed in the treatment chamber, a secondary solid-liquid separation mechanism is provided with a circuitous waterway structure, which is communicated with a filter screen cabin through a lower filter screen, and communicated with a lower part of a filter box through an outlet pipe, wherein a plurality of filter elements aredetachably installed in the filter box, suspended on the upper part of the filter box respectively, the plurality of filter elements are communicated with a clean water tank, and the clean water tankis communicated with a working nozzle of a washing and sweeping vehicle.

Description

technical field [0001] The invention relates to the technical field of sanitation equipment, in particular to a sewage recycling device for a washing and sweeping vehicle and a sewage treatment method thereof. Background technique [0002] Sewage recycling technology for sweeper vehicles collects, filters and purifies sewage on the road surface to realize sewage recycling, thereby saving the trouble of repeatedly going to the water station for refilling clean water and discharging sewage at the garbage station for the sweeper, and greatly improving the operation efficiency of the sweeper At the same time, it can also reduce the sewage discharge of car washing and sweeping operations, improve the reuse rate of water, and achieve the purpose of saving water. Therefore, sewage recycling technology has always been an important direction for the research and development of car washing and sweeping technology, and major domestic manufacturers are actively carrying out related tech...
