Road cleaning sweeper truck with sewage recovery and reutilization function

Abstract

The invention relates to a road cleaning sweeper truck with a sewage recovery and reutilization function. The sweeper truck comprises a truck body and a clean water tank, wherein the clean water tank and a sewage tank are separated by a retaining plate, and are respectively and fixedly arranged on a chassis, a suction pipe penetrates through the chassis and extends into the sewage tank, the bottom of the suction pipe is connected with a suction nozzle for cleaning, a polymer sintering membrane filter is arranged at the top end in the sewage tank, a sewage pump is arranged in the sewage tank, and is connected with the polymer sintering membrane filter through a pipeline, a filtering water outlet pipe extends to an opening at the top of the clean water tank along the outer edge of the sewage tank by passing through the polymer sintering membrane filter, a backwashing pipe is connected with the polymer sintering membrane filter, and the opening of the backwashing pipe is provided with a backwashing valve. The sweeper truck has the advantages that the space structure of the sewage tank of the sweeper truck is sufficiently utilized by the horizontal type polymer sintering membrane, the problem of overlarge occupation space when the polymer sintering membrane filter is vertically arranged is solved, the filtering flow quantity of the polymer sintering membrane is approximate to the constant flow quantity in the specific application, and the filtering pressure in the sewage cavity is increased; the problems of overhigh initial flow quantity and difficult control over constant flow quantity are solved.

Description

technical field [0001] The invention relates to the field of sewage purification and treatment, in particular to a road cleaning and sweeping vehicle capable of recycling and reusing sewage. Background technique [0002] The road cleaning and sweeping vehicle is a road cleaning machine with high cleaning efficiency and good cleaning effect. This product has been welcomed by sanitation users in various cities since it was first introduced to the market. [0003] However, the high operating cost of road cleaning and sweeping vehicles, especially the short operation time of adding water once, the large water consumption, and the large amount of sewage recovery seriously affect the further promotion and use of road cleaning and sweeping vehicles. Cleaning operations on the main roads of the city. [0004] Road cleaning and sweeping vehicle manufacturers have been looking for a way to recycle and recycle sewage to extend the interval between water additions, reduce the time to r...
