Description
Technical field
The utility model relates to sanitation equipment technical field more particularly to a kind of sweeper sewage circulation units.
Background technique
Sweeper effluent cycle technology realizes sewage recycling by road surface sewage collecting and filtration, purification, thus
It saves sweeper to remove water station filling clear water repeatedly and go the trouble of refuse depot sewage effluent, is greatly improving sweeper operating efficiency
While, additionally it is possible to the sewage discharge for reducing sweeper operation improves the recycling rate of waterused of water, achievees the purpose that water conservation.
Therefore, effluent cycle technology is always the important directions of sweeper technical research, and domestic main production firm actively develops correlation

Sewage water filtration technology is that sweeper realizes that effluent cycle is always related-art technology research and development heat using key point
Point and difficult point.It is restricted by filtering material technology, for many years although sewage water filtration technology achieves many research achievements, but still
It does not make a breakthrough, the problems such as sewage water filtration low efficiency and filter of sweeper easily block is prominent.And practical application
Strainability reduces feedback after a period of use, and sustainability is poor (when just having begun to use effect fair, but having used one section
Between after filtering traffic and precision substantially decay), replacement filtering material is inconvenient and problem with high costs.
And it makes a general survey of sewage water filtration field such as sewage treatment plant, diafiltration liquid processing device etc. and can be generated long lasting for property and is good
Good filter effect.Comparison reason also has sweeper filtering operating condition different, and usually vehicle filters it in operation and requires filtering
The complete time is short (vibration is severe and sewage lacks " sedimentation " process), and the narrow limitation of filter space filters terminal (filter stick etc.)
Long period of soaking is in the medium reason of muddy sewage.
In addition, the clear water after having filtered is pumped to filtered water tank using sewage pump by existing sweeper sewage circulation unit,
In order to avoid suction pump is into air impact suction effect, when suction filtration, needs for filtering terminal to be fully immersed in (dirt) water,
Filter sewage open ended in this way is also by limitation (time for allowing to filter during continuous operation also just shortens).Therefore " interior
Set " technically in the presence of originating, filtered points are high, sewage available for filtration is less, filtration time requirement is short (filters and flows formula filter device
Amount requires big) defect.
