Description

A self-cleaning dust-free material water tank device

Technical field

The utility model relates to a material water tank device used for garbage settlement collection and airflow water washing and dust removal of various road sweepers. The road sweeper is a special vehicle for sanitation cleaning and cleaning operations.

Background technique

When the road sweeper is working, the fan installation system operates to provide the vacuum negative pressure airflow required for the absorption and lifting of ground garbage. This device is located between the fan installation system and the suction nozzle device, and is used for garbage settlement collection and airflow dust removal. After the work is completed, the device is tipped over, and the garbage and sewage contained in it are poured into the specified place. The conventional method is that the negative pressure airflow carries garbage and dust into the material box device, and the airflow in the larger cavity of the material box device decelerates to make the garbage settle at the bottom of the material box. The water mist removes the dust in the airflow, and then discharges to the outside of the vehicle through the fan system. At this time, a special water tank is used to store water, and the water is supplied to the water nozzle through the water pump to continuously spray and remove dust. However, the dust removal effect of water spray is limited, which often causes secondary pollution of the air discharge. At the same time, part of the water mist enters the fan with the air flow, causing stagnant water and corrosion. Therefore, it is necessary to completely remove the dust in the airflow in the hopper to improve the performance of the road sweeper.

Utility model content

In order to meet the requirements of the background technology and overcome the shortcomings and deficiencies of the background technology, the utility model provides a self-cleaning dust-free material water tank device.
