A washing and sweeping vehicle with a single circulation filter system

Abstract

The invention relates to a sweeping car with a single-cycle filtering system. The sweeping car comprises a car chassis, a draught fan, a pumping air flue, a pumping pipe, a pumping disc, a sweeping disc and a water spraying device, wherein the single-cycle filtering system is arranged on the car chassis; the single-cycle filtering system comprises a filter, a sewage tank, a clean water tank, a water pump and a connection pipeline; the sewage tank is connected with the water pump through a pipeline; the water pump is connected with one or more than one filters through a pipeline; the filter is connected with the sewage tank through a pipeline; the filter is provided with a clean water outlet; the clean water outlet is connected with the clean water tank through a pipeline; the filter is a ceramic film filter; the ceramic film filter is formed by arranging a ceramic film pipe in a sealed shell; the two ends of the sealed shell are respectively used as a sewage inlet and a sewage outlet which are connected with a pipeline; the sealed shell is provided with a clean water outlet. The sweeping car with the single-cycle filtering system, provided by the invention, can be widely used for environmental sanitation cars cleaning urban streets; the effective sweeping working time of the sweeping car can be greatly improved, the number of times of filling clean water into the working car at a water station and discharging sewage in a refuse dump is reduced; the purchasing and using cost of cars in a unit working area can be reduced, the emission amount of the sewage is reduced and the utilization rate of water resources is improved.

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 single-cycle 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. Effective operating time of the vehicle. Therefore, sanitation vehicles using sewage filte...

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
