Abstract

The invention relates to a fan muffling device and a road cleaning vehicle. The fan muffling device comprises a shell (1) and a dust reduction and noise reduction structure (2) arranged in the shell (1). The shell (1) is provided with an inlet (11) and an outlet (12). The dust reduction and noise reduction structure (2) is located on a flowing path between the inlet (11) and the outlet (12) and isinternally provided with a muffling cavity (A). At least part of airflow entering the shell (1) from the inlet (11) is discharged from the outlet (12) after passing through the muffling cavity (A). The dust reduction and noise reduction structure in the fan muffling device serves as an overall structure and has both dust reduction and noise reduction functions, dust carried in the airflow at thefan outlet can be separated out, noise of a fan can also be reduced, meanwhile with the structure, the structure of the fan muffling device can be more compact, and duct removal and noise reduction needs of the fan in the road cleaning vehicle can be met.

Description

technical field [0001] The invention relates to the technical field of sanitation machinery, in particular to a fan muffler and a road cleaning vehicle. Background technique [0002] During the operation of the road sweeper, due to the suction effect of the centrifugal fan, different types of garbage enter the suction nozzle, garbage bin and fan in sequence with the high-pressure airflow, and then are discharged into the atmosphere again. However, fan noise is the main sound source, and its working noise is discharged without treatment, which will inevitably cause some interference to the lives of operators and surrounding residents. At the same time, the airflow at the outlet of the fan is mixed with floating dust, fine sand and other small-quality garbage, which will cause secondary dust after being directly discharged into the atmosphere. [0003] The current road sweeper generally installs air ducts or pipe mufflers at the outlet of the fan to reduce the noise of the fa...
