Problems solved by technology

The conventional filtration system currently used in the market is not only huge in size, seriously occupying the limited space of the cleaning vehicle, but also has low sewage treatment efficiency, and the filter screen is easily blocked and difficult to clean. It has the characteristics of short working cycle and high maintenance cost.
[0003] The patent No. CN203899295U applied by Fujian Longma Environmental Sanitation Equipment Co., Ltd. is a "recycling device for reclaimed water for washing and sweeping vehicles". It uses PE sintered membrane as the filter membrane, which is easy to clog and needs to be cleaned manually after each use.
Zoomlion’s patent No. CN102561241A “Control method, device and system for washing and sweeping vehicles” adopts the method of pumping out the air and water in the filtration membrane for pressure filtration. The biggest disadvantage of this filtration method is The pressure difference inside and outside the membrane is small, the filtration efficiency is low, and the filter membrane is easy to clog, difficult to clean, and difficult to maintain
[0004] Although the ceramic membrane filter has been used in the field of liquid medicine purification, but its volume is very large, so it is the first time to apply it in the cleaning vehicle. How to maximize the inherent space of the cleaning vehicle is a problem that must be solved

Abstract

The invention discloses a sewage filtering system with transverse ceramic membrane filters. The sewage filtering system comprises the filters, a sewage tank, a clear water tank, a water pump and connecting pipelines; the sewage tank is connected with the water pump through the pipeline, the water pump is connected with one or more filters through the pipelines, the filters are connected with the sewage tank through the pipelines, each filter is provided with a clear water outlet, and the clear water outlets are connected with the clear water tank through the pipelines; the filters are the ceramic membrane filters and each comprises a ceramic membrane tube which is arranged in a sealed shell, the two ends of the sealed shell serve as a sewage inlet and a sewage outlet respectively to be connected with the pipelines, and the ceramic membrane filters are arranged transversely. The sewage filtering system with the transverse ceramic membrane filters can be widely applied to environmental sanitation vehicles for cleaning urban streets, the effective washing and sweeping operating time can be greatly reduced, the frequency of the operating vehicle for being filled with clear water to a water station and discharging the sewage to a garbage dump is decreased, the vehicle purchase and use cost in unit operating area can be reduced, the sewage discharge can be reduced, and the use ratio of water resource can be increased.

Description

technical field [0001] The invention belongs to the technical field of special sanitation vehicles, and in particular relates to a sewage filtration system with a horizontal ceramic membrane filter, which is mainly used for the sewage filtration and recovery work of sanitation cleaning and sweeping vehicles. Background technique [0002] With the wide application of road cleaning vehicles in the sanitation industry, how to improve the effective operating time of cleaning vehicles and reduce the purchase and use costs of cleaning vehicles per unit operating area has become a new research topic. At present, the sewage collected by conventional vehicles on the market after washing the road surface is generally discharged directly, which not only causes waste of water resources, but also needs to repeatedly go to the water station to fill with clean water and discharge sewage to the garbage station, which greatly limits cleaning. Effective operating time of the vehicle. Therefo...
