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

Abstract

The invention discloses a washing and sweeping vehicle with a double-circulation filter system. The washing and sweeping vehicle comprises a vehicle chassis, a draught fan, a suction air duct, a suction pipe, a suction plate, a brush plate and a water spraying device. According to the double-circulation filter system, a sewage box is connected with a first-stage water pump through a pipeline, the first-stage water pump is connected with a second-stage water pump through a pipeline, the second-stage water pump is connected with one or more filters. The filter is connected with the sewage box through a pipeline. A pressure regulation valve is arranged on the connection pipeline between the filter and the sewage box. The connection pipeline between the first-stage water pump and the second-stage water pump is connected with the connection pipeline between the filter and the pressure regulation valve through a pipeline. The clear water outlet of the filter is connected with a clear water box through a pipeline. The filter is a ceramic membrane filter which comprises a ceramic membrane pipe arranged in a sealed shell. The two ends of the sealed shell are used as a sewage inlet and a sewage outlet respectively to be connected with pipelines. A clear water outlet is formed in the sealed shell. By means of the washing and sweeping vehicle, the effective working time of environmental sanitation devices can be greatly prolonged, the sewage discharge amount can be decreased, and the utilization rate of water resources is increased.

Description

technical field [0001] The invention belongs to the technical field of special sanitation vehicles, and in particular relates to a washing and sweeping vehicle with a double-circulation filtering system, which is mainly used for sanitation and maintenance of road surfaces. 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. The effective working time of the vehicle. Therefore, sanitation vehicles using sewa...
