Problems solved by technology

However, the conventional filtration system is only carried out through multi-stage filter screens. Not only is the sewage treatment efficiency low, but also the filter screens are easily blocked, the working cycle is short, and the maintenance cost is extremely high.
[0003] However, for urban streets with complex road conditions, the garbage sucked by the sweeper includes leaves, branches, garbage bags, etc. If no effective measures are taken, these garbage will easily block the filtration system, thus affecting the use of the sewage filtration system efficiency
[0004] 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

Abstract

The invention discloses a ceramic membrane sewage filter system with automatically-vibrating filter screens. The ceramic membrane sewage filter system comprises a sewage tank, a clean water tank, a water pump and connecting pipelines. The sewage tank is connected with the water pump through the corresponding pipeline, the water pump is connected with one or more ceramic membrane filters through the corresponding pipelines, the ceramic membrane filters are connected with the sewage tank through the corresponding pipelines, and clean water outlets of the ceramic membrane filters are connected with the clean water tank through the corresponding pipelines. The ceramic membrane filters are formed by arranging ceramic membrane pipes in sealed shells, the sealed shells are provided with clean water outlets, and the two ends of each sealed shell serve as a sewage inlet and a sewage outlet respectively and are connected with the corresponding pipelines. The automatically-vibrating filter screens are installed in the sewage tank, and vibrating pumps are installed on the automatically-vibrating filter screens. A pressure gage and a pressure switch are installed on the pipeline through which the sewage tank and the water pump are connected. The ceramic membrane sewage filter system can be widely applied to sewage treatment under harsh road conditions, and the sewage circulating filter system can be effectively prevented from being blocked. A cleaning and sweeping vehicle with the ceramic membrane sewage filter system can greatly prolong effective operating time, reduce vehicle purchase and use cost per unit operating area, reduce the emission of sewage and increase the utilization rate of water resources.

Description

technical field [0001] The invention belongs to the technical field of special sanitation vehicles, and in particular relates to a ceramic membrane sewage filtration system with an automatic vibrating filter net, 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 veh...
