Compared with the prior art the present invention has following distinguishing feature and positively effect: the present invention is arranged on the car body of the below of foul water tank, take full advantage of the intrinsic space of environmental sanitation sweeper, rational deployment, the single that the employing of single loop filtering 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.The employing of purpose ceramic-film filter mainly utilizes the cross flow filter principle of ceramic membrane, vitrified pipe gathers pore, during filtration, diameter is less than the partial impurities in pore aperture and part clear water can pass through pore, remaining most of impurity is then flushed to outside purpose ceramic-film filter by high velocity flow, the impurity flowed through in ceramic membrane can be made to be attached to ceramic membrane surface, keep good filter effect for a long time, filtration efficiency is high, and maintenance cost is low.
In foul water tank, set up liquid level sensor and set up valve in ceramic membrane filter system; when the sewage in foul water tank can be made to reach liquid level sensor position; ceramic membrane filter system starts automatically; easy to operate;, add the level of automation of system, when sewage is lower than liquid level sensor; ceramic membrane filter system is closed automatically, can protect water pump and strainer.
Ceramic-film tube in purpose ceramic-film filter erects the precipitation and blocking of putting and can effectively prevent sewage when flowing through ceramic-film tube with tilting, and the lateral arrangement of ceramic-film tube can utilize the finite space of sweeper better.
The purpose ceramic-film filter of sectional type adopts between multiple segment filters section by the fixing composition one of coupling device, compared to the monoblock type purpose ceramic-film filter of same length, while meeting filtering requirement, replacement charge 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 tightness system that between ceramic-film tube in purpose ceramic-film filter and the two ends of purpose ceramic-film filter 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 adjust according to the finite space of sweeper, effective working length of maximum raising 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 sectional type ceramic membrane, laterally different axle, longitudinally coaxial, longitudinal different axle, oblique coaxial, oblique different axle all can adjust according to the finite space of sweeper, farthest improve effective working length of purpose ceramic-film filter.
Purpose ceramic-film filter shell adopts the corrosion resistant material such as stainless steel, macromolecular material and matrix material effectively can prevent purpose ceramic-film filter corrosion in use and oxidation, improves the work-ing life of purpose ceramic-film filter.
The back flushing mouth that purpose ceramic-film filter is arranged, is convenient to utilize pressurized air and current to carry out counterflush to purpose ceramic-film filter, more effectively can removes the impurity be blocked in ceramic-film tube internal surface pore.
The compressed air back-washing function that ceramic membrane filter system has can use high-pressure air to carry out back flushing by back flushing mouth to purpose ceramic-film filter, and flush efficiency is high, and saves the water yield needed for cleaning.
Ceramic membrane filter system can also have clear water backwashing function, and this function can use High-Pressure Water to carry out back flushing by back flushing mouth to purpose ceramic-film filter, and flush efficiency is high, and the cleaning time length is more permanent, and cleaning performance is good.
Ceramic membrane filter system can also have strong cleaning function, by adding strong acid solution and strong base solution in strong cleaning case, the organic impurity that ceramic membrane internal surface grows because of not using for a long time can be removed, organic impurity is generally liver moss and phycophyta, and conventional purging method is difficult to remove.
The present invention can also be provided with automatic vibration filtering net, the sewage be pumped in foul water tank due to suction disc comprises leaf, the bulky refuses such as plastics bag, if do not carry out coarse filtration, be easy to blocking ceramic membrane filter system, therefore automatic vibration filtering net 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 filtering net 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 filtering net will be attached to shake off, make the filtration condition that filtering net remains good.
