Certain angle of inclination, be arranged vertically refer to purpose ceramic-film filter axis perpendicular to sweeper chassis plane.
Compared with the prior art the present invention has following distinguishing feature and good effect：The present invention is arranged under foul water tank
On the car body of side, the intrinsic space of environmental sanitation sweeper, rational deployment are taken full advantage of；The use of Two-way Cycle sewage filter system is big
The single of width raising sweeper is washed and sweeps the activity duration, is reduced sweeper backhaul and is added water and the sewage effluent time, is reduced unit and is made
Sweeper in industry area is purchased and use cost, the connecting line between I and II water pump and filter and pressure-regulating valve
Between connecting line connected by pipeline, form secondary cycle loop, secondary cycle loop can greatly improve and flow through filtering
The effluent flow rate of device, prevents contamination precipitation and blocking in sewage, while greatly improving the filter efficiency of sewage.Ceramic membrane filter
The use of device mainly utilizes its cross-flow filtration principle, and the impurity that high-velocity flow can be flowed through in ceramic membrane without being adhered to ceramic membrane
Surface, can for a long time keep preferable filter effect, and filter efficiency is high, and maintenance cost is low.
Liquid level sensor is set up in foul water tank and valve is set up on circulating and filtering system, can made in foul water tank
When sewage reaches liquid level sensor position, circulating and filtering system automatic is easy to operate, increased the automation of system
Degree, when sewage is less than liquid level sensor, circulating and filtering system is automatically switched off, and can protect water pump and filter.
Ceramic-film tube in purpose ceramic-film filter is vertically arranged can effectively prevent sewage by the heavy of ceramic-film tube with tilting
Form sediment and block, and the lateral arrangement of ceramic-film tube can better profit from the confined space of sweeper.
The purpose ceramic-film filter of segmented fixes composition one using between multiple segment filters section by attachment means, compared to
The monoblock type purpose ceramic-film filter of same length, while filtering requirement is met, can reduce whole breakage of ceramic-film tube and
Renewal cost during blocking, easy to disassemble and maintenance, reduces use cost.
Between ceramic-film tube in purpose ceramic-film filter and the seal shock-proof device that is provided with of two ends of fillter section can have
Effect prevents the Seepage of sewage during filtering, and the sealing device is rubber, silica gel elastomeric material, has the effect of damping concurrently, is subtracted
The breakage that few ceramic membrane is produced by vibrations.
Purpose ceramic-film filter is horizontal, oblique or is longitudinally arranged the tune that can be arranged according to the confined space of sweeper
Whole, its arrangement is not limited to above-mentioned three kinds, can also laterally, longitudinal direction, oblique three kinds simultaneously use, farthest exist
Effective active length of purpose ceramic-film filter is improved on the basis of intrinsic space, and it is longitudinal and diagonally disposed, can effectively prevent
The precipitation and blocking of rubbish in sewage in filter.
The transverse uniaxial of segmented ceramic membrane, laterally different axle, longitudinally coaxial, the different axle in longitudinal direction, oblique coaxial, oblique different axle are equal
Can be adjusted according to the confined space of sweeper, farthest improve effective active length of purpose ceramic-film filter.

Secondary pressurization, the sewage after pressurization reaches two grades of water pumps 39 by pipeline, and carries out secondary pressurized, and the sewage after secondary pressurized passes through
Pipeline reaches filter 3, and is filtered, and the clear water after filtering flows out from the clear water output 5 of filter 3, and by pipeline stream
Enter filtered water tank 2, a remaining sewage part flows back to foul water tank 1 by pipeline and pressure-regulating valve 26 after filtering, and another part is dirty
Water is back to two grades of water pumps 39 by pipeline, and carries out pressure filtration again；If purpose ceramic-film filter 3 is not used for a long time, pottery
The inner surface of porcelain membrane tube 6 easily grows the foreign organic matters such as liver moss, algae, is difficult to effectively removal using conventional cleaning way, now
Need to be cleaned by force, to strong base solution is injected in strong cleaning case 30, valve 32, valve 40, valve 28 are opened, remaining valve is closed
Close, strong base solution flows out from strong cleaning case 30, one-level water pump 4 and two grades of water pumps 39 are reached by valve 32, then highly basic is molten
Liquid reaches purpose ceramic-film filter 3 by pipeline and valve 28, highly basic cleaning is carried out subsequently into purpose ceramic-film filter 3, after filtering
Strong base solution flowed out from clear water output 5, flow back to strong cleaning case 30 by pipeline and valve 40, remaining strong base solution after filtering
Discharged from the outlet of sewer of purpose ceramic-film filter 3, foul water tank 1 flowed back to by valve 26 and pipeline, highly basic scavenging period is 30 seconds,
After the completion of highly basic cleaning, valve 29 is opened, and by remaining strong base solution discharge in strong cleaning case 30, and is held and special container
In, clear water flushing is then carried out, valve 27, valve 28, valve 25 and valve 26 are opened, remaining valve closing, and clear water is from clear water
Flowed out in case 2, water pump 4 is reached by valve 27, clear water reaches the wastewater inlet of purpose ceramic-film filter 3, Ran Houjin by pipeline
Entering purpose ceramic-film filter 3 carries out clear water cleaning, and the clear water after filtering flows out from clear water output 5, is flowed back to by pipeline and valve 25
Filtered water tank 2, remaining sewage is discharged from outlet of sewer and flows back to foul water tank 1 by valve 26 after filtering, and this process carries out 10 points
Clock.Then strong acid cleaning is carried out, to strong acid solution is injected in strong cleaning case 30, cleaning process is consistent with highly basic cleaning process, clearly
The time is washed for 30 seconds, is cleaned 10 minutes using clear water again after the completion of strong acid cleaning, complete strong cleaning process.
As Figure 20, circulating and filtering system are additionally provided with automatic vibration screen pack 35, described automatic vibration screen pack 35 is pacified
Mounted in the bottom of foul water tank 1, vibration pump 34, foul water tank 1 and one-level water are also provided with described automatic vibration screen pack 35
Pressure gauge 36 and pressure switch 37 are also equipped with the pipeline of the connection of pump 4, when the described normal work of circulating and filtering system
When making, sewage flows out from foul water tank 1, by screen pack coarse filtration, can be by leaf, the isometric larger rubbish filtering of refuse bag
Fall, the sewage after coarse filtration reaches one-level water pump 4 and two grades of water pumps 39 by the road, the sewage after secondary pressurized enters filter 3, mistake
Clear water after filter is flowed out from clear water output 5, and filtered water tank 2 is reached by pipeline, and a remaining sewage part passes through pipeline after filtering
Foul water tank 1 is flow to, another part again flows into two grades of water pumps 39 and carries out pressure filtration again by pipeline.When automatic vibration mistake
When the surface of filter screen 35 is covered by rubbish, there is negative pressure in the connecting line between foul water tank 1 and water pump 4, when in the pipeline
Negative pressure is reached when to a certain degree, and pressure switch 37 detects pressure signal, and feedback signal, starting shock pump 34, it is described from
Dynamic vibrations screen pack 35 can be one layer, two-layer, or the mesh aperture of multiple filtration net, two-layer and multiple filtration net can
With difference.
