The ceramic membrane filter described in the utility model can be arranged horizontally, obliquely or vertically. The horizontal arrangement means that the axis of the ceramic membrane filter is parallel to the plane of the chassis of the cleaning vehicle. The plane of the chassis of the car is inclined at a certain angle, and the vertical arrangement means that the axis of the ceramic membrane filter is perpendicular to the plane of the chassis of the washing machine.

Compared with the prior art, the utility model has the following remarkable features and positive effects: the utility model is arranged on the car body below the sewage tank, fully utilizes the inherent space of the sanitation cleaning and sweeping vehicle, and has a reasonable layout and integral ceramic membrane filtration The adoption of the sewage treatment system of the sweeper greatly improves the single cleaning operation time of the sweeper, reduces the return time of the sweeper to add water and discharge sewage, and reduces the purchase and use cost of the sweeper per unit operating area. The ceramic membrane filter is mainly based on the cross-flow filtration principle of the ceramic membrane. The ceramic tube is densely covered with capillary pores. When filtering, some impurities and part of the clean water with a diameter smaller than the capillary pore diameter can pass through the capillary pores, and most of the remaining impurities are absorbed by the high-speed water flow. Flushing out of the ceramic membrane filter can prevent impurities flowing through the ceramic membrane from adhering to the surface of the ceramic membrane, maintaining a good filtration effect for a long time, high filtration efficiency, and low maintenance costs.

Adding a liquid level sensor in the sewage tank and adding a valve to the sewage treatment system can make the sewage treatment system automatically start when the sewage in the sewage tank reaches the position of the liquid level sensor, which is easy to operate and increases the automation of the system. When it is lower than the liquid level sensor, the sewage treatment system is automatically shut down, which can protect the water pump and filter device.

The vertical and oblique placement of the ceramic membrane tubes in the ceramic membrane filter can effectively prevent the sedimentation and clogging of sewage passing through the ceramic membrane tubes, and the horizontal arrangement of the ceramic membrane tubes can make better use of the limited space of the washing machine.

Under the conditions of shock absorption, the integral ceramic membrane filter can be built with the largest length of ceramic membrane tube, so that its filtration efficiency is the highest.

The sealing device between the ceramic membrane tubes and at both ends of the ceramic membrane filter can effectively prevent the leakage of sewage during filtration. The sealing device is made of elastic materials such as rubber and silica gel, which has the effect of shock absorption and reduces the amount of ceramic Membrane damage due to vibration.

The ceramic membrane filter shell is made of corrosion-resistant materials such as stainless steel, polymer materials and composite materials, which can effectively prevent the corrosion and oxidation of the ceramic membrane filter during use, and improve the service life of the ceramic membrane filter.

The backwash port set by the ceramic membrane filter is convenient for backwashing the ceramic membrane filter with compressed air and water flow, and can more effectively remove impurities blocked in the capillary pores on the inner surface of the ceramic membrane tube.

The compressed air backwash function of the sewage treatment system of the integral ceramic membrane filter can use high-pressure air to backwash the ceramic membrane filter through the backwash port, which has high flushing efficiency and saves the amount of water required for cleaning.

The sewage treatment system of the integral ceramic membrane filter can also have the function of backwashing with clear water. This function can use high-pressure water to backwash the ceramic membrane filter through the backwash port, with high flushing efficiency, longer cleaning duration and good cleaning effect. .

The sewage treatment system of the integral ceramic membrane filter can also have a strong cleaning function. By adding strong acid solution and strong alkali solution to the strong cleaning tank, the organic impurities and organic impurities that have grown on the inner surface of the ceramic membrane due to long-term non-use can be removed. Usually moss and algae, difficult to remove with conventional cleaning methods.

The utility model can also be provided with an automatic vibrating filter net. Since the sewage sucked into the sewage tank by the suction plate contains large garbage such as leaves and plastic bags, if the coarse filtration is not performed, the ceramic membrane filter system is easily blocked, so the automatic vibration The filter screen can classify large garbage, medium garbage and small garbage in the sewage, thereby avoiding the clogging of the ceramic membrane filter. When there are many garbage attached to the filter, the water pump will not suck enough water. Negative pressure is generated in the pipeline, and when the pressure switch in the pipeline detects the set negative pressure signal, the feedback signal starts the vibrating pump to shake off the garbage attached to the filter net, so that the filter net always maintains a good filtering state.
