Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, illustrated embodiment is served only for explaining this reality
With novel, it is not intended to limit the scope of the utility model.
Embodiment
As shown in Figure 1-3, it includes: self-cleaning filter 1 that sweeper back-purge system, which includes:, self-cleaning filter 1 is intake
Mouth is sequentially connected the first backwash inlet valve 13, intake pump 12, the first solenoid valve 11 and Primary filter system 10 by water pipe, just
Grade filtration system is used to filter the sewage of sweeper dirt sucking tube sucking, and 1 water outlet of self-cleaning filter is connected by water pipe and is pressurized
Water tank 2, pressure tank 2 are sequentially connected second solenoid valve 3, booster pump 4, bag filter 5, accurate filter 6, by water pipe
Two backwash inlet valves 7, third solenoid valve 8 and filtered water tank 9, wherein after booster water pump starting, on the water level in pressure tank
It rises, the air in pressure tank is compressed, and air pressure is generated, and because of gas pressure, the water in pressure tank can flow out at a high speed, pressurization
After water level decreasing in water tank, air pressure is reduced, when reaching setting pressure, water pump automatic starting again, and automatic cycle operation.
It is understood that sewage water filtration circulating treating system and back-purge system are the set of system of sweeper, respectively
The work and pause that two systems are controlled with different switches, at the first backwash inlet valve and the second backwash inlet valve 7
In closed state, the sewage treatment circulatory system is in running order, when the first backwash inlet valve 13 and the second backwash water inlet
Valve 7 is in the open state, and back-purge system is started to work.
Further, 1 sewage draining exit of self-cleaning filter is sequentially connected the 4th solenoid valve and sweeper upper left side by water pipe
Dirt sucking tube described in 5 sewage draining exit of bag filter the soil pick-up of the 5th solenoid valve and sweeper upper left side is sequentially connected by water pipe
Pipe；6 sewage draining exit of accurate filter is sequentially connected the dirt sucking tube 14 on right side on the 6th solenoid valve and sweeper by water pipe.
Optionally, the sewage outfalls setting of filter is in filter bottom or side wall.
Optionally, pressure sensor is installed at the top of self-cleaning filter 1, bag filter 5 and accurate filter 6, works as pressure
Force snesor senses hypertonia in filter, to start back-purge system, wherein self-cleaning filter 1, bag type filtering
The filtering accuracy of device 5 and accurate filter 6 successively improves.
Further, the first backwash inlet valve 13 is connected clearly with the second backwash inlet valve 7 by high-pressure hydraulic pump
Water tank 9, high-pressure hydraulic pump provide the impact force of hydraulic pressure to back-purge system.
Optionally, the first backwash inlet valve 13 and the second backwash inlet valve 7 can be electrically connected sweeper
Automatic control panel carry out automatically controlling, it is easy to operate, hand-operated valve can also be installed and carry out manually controlling save the cost.
Optionally, filtered water tank 9 and Primary filter system 10 can be set in the same compartment of sweeper.
Working principle:
Back-purge system is used cooperatively with sweeper effluent cycle filtration system, when sweeper sucking sewage is filtered
When, the first backwash valve and the second backwash valve are closed, and the sewage water filtration circulatory system is opened, and sewage is flowed from Primary filter system 10
It enters from the inlet in self-cleaning filter 1 through water pipe, and is flowed out from the water outlet of self-cleaning filter 1, flow through pressure tank
2, water is pumped into bag filter 5 by booster pump 4, then water passes through accurate filter 6, finally enters the completion of filtered water tank 9
Primary filtering.
When sewage impurity is more in back-purge system, pressure sensor induction, back-purge system is automatically opened, sewage water filtration
The circulatory system is closed or break-off, and the first backwash inlet valve 13 or/and the second backwash inlet valve 7 are opened, third electromagnetism
Valve 3 closes (prevent from being formed straight-through, influence backwash effect), and the clear water in filtered water tank 9 is pumped into filter by high-pressure hydraulic pump
In filter is rinsed, the sewage after flushing is inhaled into foul water tank along water pipe by solenoid valve, dirt sucking tube.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
