Single-engine washing and sweeping vehicle with ceramic membrane filter system

Abstract

The invention provides a single-engine washing and sweeping vehicle with a ceramic membrane filter system. The single-engine washing and sweeping vehicle comprises a drive system, the ceramic membrane filter system, a vehicle chassis, a suction draught fan, a suction air duct, a suction pipe, a suction disc, a brush disc, a high-pressure water pump and a water spray device. An engine is adopted in the drive system and connected with a full-power power takeoff. The full-power power takeoff is connected with a clutch through a connecting device. The clutch is connected with a gearbox. An output shaft of the gearbox is connected with a drive auxiliary device. A transmission is simultaneously arranged on the full-power power takeoff and drives a rear axle through a transmission shaft. The single-engine washing and sweeping vehicle can be widely applied to road washing and sweeping work of urban roads, the effective washing and sweeping operation time can be prolonged to a great extent, the frequency of the operating vehicle going to a water station for clean water injection and the frequency of the operating vehicle going to a dump for sewage drainage are reduced, the vehicle purchase and use cost in the unit operation area can be reduced, the drainage amount of sewage is reduced, and the use rate of water resources is increased; and the single engine is used so that not only can the limited space of the washing and sweeping vehicle be saved, but also the emission of tail gas can be reduced to a great extent.

Description

technical field [0001] The invention belongs to the technical field of special sanitation vehicles, and in particular relates to a single-engine washing and sweeping vehicle with a ceramic membrane filtration system, which is mainly used for sanitation and maintenance of road surfaces. Background technique [0002] With the wide application of road cleaning and sweeping vehicles in the sanitation industry, how to improve the efficiency of sanitation vehicles, reduce vehicle purchase costs and exhaust emissions has become a new research topic. Since the sanitation vehicle requires the fan to have a higher speed and a lower vehicle speed during work, the conventional sanitation vehicles currently on the market basically use dual engines, the chassis engine mainly drives the vehicle, and the auxiliary engine mainly drives the fan. The movement of working parts such as water pumps. The sanitation vehicle with a single engine can use one engine to drive the driving of the vehicl...

AI Technical Summary

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.

[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
