Single-cycle filtering system for washing and sweeping vehicle

Abstract

The invention discloses a single-cycle filtering system for a washing and sweeping vehicle. The single-cycle filtering system comprises a drain tank, a clear water tank, a water pump and connecting pipelines. The drain tank is connected with the water pump through the corresponding pipeline. The water pump is connected with one or more filters through the corresponding pipelines. The filters are connected with the drain tank through the corresponding pipelines. Clear water outlets of the filters are connected with the clear water tank through the corresponding pipelines. The filters are ceramic membrane filters. According to the ceramic membrane filters, ceramic membrane pipes are arranged in a sealed shell, the two ends of the sealed shell serve as a sewage inlet and a sewage outlet respectively, the sewage inlet and the sewage outlet are connected with the pipelines, and a clear water outlet is formed in the sealed shell. The single-cycle filtering system can be widely used for an environmental sanitation vehicle for cleaning urban streets, the effective washing and sweeping work time of the washing and sweeping vehicle can be greatly prolonged, the frequency at which the working vehicle goes to a water station for injecting clear water and the frequency at which the working vehicle goes to a garbage dump for discharging wastewater are decreased, the vehicle purchase and use cost within the unit working area can be reduced, the wastewater discharge volume can be decreased, and the water resource utilization rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of special sanitation vehicles, and in particular relates to a single-cycle filtering system applied to a cleaning vehicle, which is mainly used in the sewage filtration and recovery work of the cleaning vehicle. 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. Therefore, sanitation vehicles using...

AI Technical Summary

Problems solved by technology

The conventional filtration system currently used in the market is not only huge in size, which seriously occupies the limited space of the cleaning vehicle, but also has low sewage treatment efficiency, and the filtration device 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
