Sewage Filtration Systems and Cleaning Carts

Abstract

The invention discloses a sewage filtering system, which comprises a sewage area, a clean water area, a first water pump and a filtering device which is arranged in the sewage area. The first water pump can be used for pumping clean water filtered by the filtering device to the clean water area. The first water pump is communicated with the clean water area through a first pipeline. A backwashing pipeline is arranged between the clean water area and the drain port of the filtering device. The backwashing pipeline is communicated with the clean water area through a water inlet which is formed in the side wall of the clean water area. The height of the water inlet in the vertical direction is larger than the height of the filtering device to form height difference. The invention additionally discloses a sanitation vehicle using the sewage filtering system. Since the sewage filtering system provided by the invention can respectively realize the goals of pumping the clean water to the clean water area and using the backwashing the filtering device with the clean water under the effect of water pressure difference through the opening and the closing of the backwashing pipeline, the service life of the filtering device can be prolonged, and the working durability of the filtering device can be improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage filtering system and a cleaning vehicle using the sewage filtering system. Background technique [0002] With the improvement of the urban living environment, cleaning vehicles such as road sweepers, sweepers, wall washers, and guardrail cleaners among sanitation vehicles are increasingly being used in road cleaning. At present, various cleaning vehicles are usually equipped with garbage bins for transferring and storing garbage, and conventional garbage bins only complete the work of storing or transferring. With the increasing scale of urban roads, cleaning vehicles such as cleaning vehicles need to clean the roads for a long time. In order to prolong the working time of the above-mentioned cleaning vehicle, it is necessary to effectively utilize the space of the vehicle body, especially to improve the dustbin to make full use of the dustbin, thereby improving the use ...
