Compared with the prior art the present invention has following distinguishing feature and good effect: the present invention is arranged on the car body of the below of foul water tank, takes full advantage of the intrinsic space of environmental sanitation sweeper, rational deployment; The single that the employing of Two-way Cycle sewage filter system significantly improves sweeper is washed and is swept the activity duration, reduce sweeper backhaul to add water and the sewage effluent time, the sweeper reduced in fundamental operation area is purchased and use cost, connecting line between I and II water pump is connected by pipeline with the connecting line between strainer and pressure-regulating valve, form secondary cycle loop, the effluent flow rate flowing through filter can significantly be improved in secondary cycle loop, prevent contamination precipitation and blocking in sewage, significantly improve the filter efficiency of sewage simultaneously.The employing of purpose ceramic-film filter mainly utilizes its cross-flow filtration principle, and high-velocity flow can make the impurity flowed through in ceramic membrane be attached to ceramic membrane surface, and can keep good filter effect for a long time, filter efficiency is high, and maintenance cost is low.
In foul water tank, set up liquid level sensor and set up valve on circulating and filtering system; when the sewage in foul water tank can be made to reach liquid level sensor position; circulating and filtering system starts automatically; easy to operate;, add the automaticity of system, when sewage is lower than liquid level sensor; circulating and filtering system is closed automatically, can protect water pump and filter.
Ceramic-film tube in purpose ceramic-film filter erects to be put with the tilting sewage that can effectively prevent through the precipitation of ceramic-film tube and blocking, and the lateral arrangement of ceramic-film tube can utilize the confined space of sweeper better.
The purpose ceramic-film filter of segmented adopts between multiple segment filters section by the fixing composition one of linkage, compared to the monolithic purpose ceramic-film filter of same length, while meeting filtering requirement, replacement cost when ceramic-film tube whole breakage and blocking can be reduced, be convenient to dismounting and maintenance, reduce use cost.
The Seepage of sewage when the seal shock-proof device that between ceramic-film tube in purpose ceramic-film filter and the two ends of fillter section are provided with can effectively prevent from filtering, sealing device is rubber, silica gel elastomeric material, have the effect of damping concurrently, reduce the breakage that ceramic membrane produces because of vibrations.
Purpose ceramic-film filter is horizontal, oblique or longitudinally arrange and can carry out according to the confined space of sweeper the adjustment that cloth is set up, its arrangement is not limited to above-mentioned three kinds, can also laterally, longitudinally, oblique three kinds use simultaneously, on the basis in intrinsic space, farthest improve effective active length of purpose ceramic-film filter, longitudinally and oblique layout then effectively can prevent precipitation in strainer of rubbish in sewage and blocking.
The transverse uniaxial of segmented ceramic membrane, laterally different axle, longitudinally coaxial, longitudinal different axle, oblique coaxial, oblique different axle all can adjust according to the confined space of sweeper, farthest improve effective active length of purpose ceramic-film filter.
Purpose ceramic-film filter shell adopts the resistant material such as stainless steel, macromolecular material and composite material effectively can prevent purpose ceramic-film filter corrosion in use and oxidation, improves the application life of purpose ceramic-film filter.
Sweeper of the present invention comprises automobile chassis, blower fan, pumping air channel, suction tube, suction disc, brush plate, water injector, can realize the cleaning of road pavement, cleaning and maintenance, prevents from producing reentrainment of dust during clean road surface.
The backwash mouth that purpose ceramic-film filter is arranged, is convenient to utilize compressed air and current to carry out back flush to purpose ceramic-film filter, more effectively can removes the impurity be blocked in ceramic-film tube inner surface pore.
The compressed air back-washing function that circulating and filtering system has can use pressure-air to carry out backwash by backwash mouth to purpose ceramic-film filter, and flush efficiency is high, and saves the water yield needed for cleaning.
Circulating and filtering system can also have clear water backwashing function, and this function can use High-Pressure Water to carry out backwash by backwash mouth to purpose ceramic-film filter, and flush efficiency is high, and the cleaning duration is more permanent, and cleaning performance is good.
Circulating and filtering system can also have strong cleaning function, by adding strong acid solution and strong base solution in strong cleaning case, the organic impurities that ceramic membrane inner surface grows because of not using for a long time can be removed, organic impurities is generally liver moss and algae, and conventional cleaning method is difficult to remove.
The present invention can also be provided with automatic vibration screen pack, the sewage be pumped in foul water tank due to suction disc comprises leaf, the bulky refuses such as polybag, if do not carry out coarse filtration, be easy to blocking ceramic membrane filter system, therefore automatic vibration screen pack can by the bulky refuse in sewage, medium-sized rubbish and small-sized rubbish classified filtering, thus avoid the blocking of purpose ceramic-film filter, when the rubbish that screen pack adheres to is more, water pump can because suction causes producing negative pressure in pipeline less than enough water, and when the pressure switch in pipeline detects the negative pressure signal of setting, feedback signal starting shock pump, rubbish on screen pack will be attached to shake off, make the filtration condition that screen pack remains good.
