Stagewise purpose ceramic-film filter described in the utility model can be horizontal, oblique or be longitudinally arranged, lateral arrangement refers to that the axis of purpose ceramic-film filter is parallel to sweeper chassis plane, the diagonally disposed axis referring to purpose ceramic-film filter becomes certain angle of inclination with sweeper chassis plane, is arranged vertically and refers to that the axis of purpose ceramic-film filter is perpendicular to sweeper chassis plane.
Compared with the prior art this utility model has following distinguishing feature and good effect: on the car body of the lower section that this utility model is arranged on sweeper foul water tank, take full advantage of the intrinsic space of environmental sanitation sweeper, rational deployment, the single of sweeper is greatly improved with the employing of the sewage disposal system of stagewise purpose ceramic-film filter to wash and sweep the activity duration, reducing 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, gather on earthenware pore, during filtration, diameter can pass through pore less than partial impurities and the part clear water in pore aperture, remaining major part impurity is then flushed to outside purpose ceramic-film filter by high-velocity flow, the impurity that can flow through in ceramic membrane without being adhered to ceramic membrane surface, keeping preferable filter effect for a long time, filter efficiency is high, and maintenance cost is low.
The purpose ceramic-film filter of stagewise uses between multiple segment filters section by attachment means fixing composition one, monoblock type purpose ceramic-film filter compared to same length, while meeting filtering requirement, renewal cost when whole breakage of ceramic-film tube and blocking can be reduced, readily accessible and maintenance, reduce use cost.
In foul water tank, set up liquid level sensor and in sewage disposal system, set up valve; when the sewage in foul water tank can be made to reach liquid level sensor position; sewage disposal system starts automatically; easy to operate;, add the automaticity of system, when sewage is less than liquid level sensor; sewage disposal system is automatically switched off, and can protect water pump and defecator.
Ceramic-film tube in purpose ceramic-film filter is vertically arranged and can effectively prevent sewage through the precipitation of ceramic-film tube and blocking with tilting, and the lateral arrangement of ceramic-film tube can better profit from the confined space of sweeper.
The Seepage of sewage when the seal shock-proof device that between ceramic-film tube in the purpose ceramic-film filter of stagewise and the two ends of fillter section are provided with can effectively prevent from filtering, this sealing device is rubber, silica gel elastomeric material, have the effect of damping concurrently, reduce the breakage that ceramic membrane produces because of vibrations.
Stagewise purpose ceramic-film filter is horizontal, oblique or is longitudinally arranged the adjustment can being arranged according to the confined space of sweeper, its arrangement is not limited to above-mentioned three kinds, can also laterally, longitudinally, oblique three kinds use simultaneously, on the basis of intrinsic space, farthest improve effective active length of purpose ceramic-film filter, longitudinally with diagonally disposed, can effectively prevent the precipitation in filter of the rubbish in sewage and blocking.
The transverse uniaxial of stagewise ceramic membrane, horizontal different axle, different axle longitudinally coaxial, longitudinal, oblique different axle coaxial, oblique all can be adjusted according to the confined space of sweeper, farthest improve effective active length of purpose ceramic-film filter.
Stagewise purpose ceramic-film filter shell uses the resistant material such as rustless steel, macromolecular material and composite can effectively prevent purpose ceramic-film filter corrosion in use and oxidation, improves the service life of purpose ceramic-film filter.
It is respectively provided with backwash mouth on every section of fillter section of stagewise purpose ceramic-film filter, it is easy to utilize compressed air and current that purpose ceramic-film filter is carried out back flush, can more effectively remove the impurity being blocked in ceramic-film tube inner surface pore, use pressure-air, by backwash mouth, purpose ceramic-film filter is carried out backwash, flush efficiency is high, and the water yield needed for saving cleaning；Using High-Pressure Water, by backwash mouth, purpose ceramic-film filter is carried out backwash, flush efficiency is high, cleans the persistent period more for a long time, and cleaning performance is good.
Sewage disposal system with stagewise ceramic membrane 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 can be removed because of not using for a long time, organic impurities is usually lichen and algae, and conventional cleaning method is very difficult to remove.
Sewage disposal system with stagewise ceramic membrane is also provided with automatic vibration drainage screen, the sewage being pumped in foul water tank due to suction disc comprises leaves, the bulky refuses such as plastic bag, if not carrying out coarse filtration, it is easy to block ceramic membrane filter system, therefore automatic vibration drainage screen can be 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 on drainage screen, the rubbish of attachment is more, water pump can be because suction produces negative pressure cause pipeline less than enough water in, and when the pressure switch in pipeline detects the negative pressure signal of setting, feedback signal starting shock pump, will be attached to rubbish on drainage screen shake off, drainage screen is made to remain good filtration condition.
