Abstract

The invention discloses a high-efficiency dust-removing and dust-filtering device for a sweeping-suction type sweeper, which is characterized in that it is composed of a sweeping-suction system, a three-stage filtering system and a dust-removing device outlet system; the sweeping-suction system consists of a main brush (1) and a collector A dust box (2) is formed; the three-stage filtration system is composed of a filter screen (8), a cyclone pre-filtering air duct (3) and a filter element filter (4); the outlet system of the dust removal device includes a lower air duct (6). ), the outlet of the dust removal device (7) and the vacuum fan (5); by setting up a three-stage filtration system and improving the shape of the filter air duct, the swirl flow and centrifugal force during the filtration of dust-laden gas are increased, and the dust removal efficiency of the dust removal device of the sweeper is improved. and service life; test and simulation analysis show that the dust-laden gas entering the cyclone pre-filter air duct captures and settles 98% of the gravel with a particle size of 0.1 to 1.5 mm.

Description

Technical field: [0001] The invention relates to the technical field of cleaning and sanitation vehicles, in particular to a high-efficiency dust-removing and dust-filtering device for a sweeping-suction cleaning vehicle; it is used for road cleaning of urban roads, airports, parks, shopping malls and workshops. Background technique: [0002] Road sweeper is a new type of high-efficiency cleaning equipment that integrates road cleaning, garbage recovery and transportation. It can be used for road cleaning such as urban roads, airports, parks, shopping malls and workshops. The dust removal and dust filtration device of the traditional sanitation sweeper has low dust removal efficiency and low garbage recovery rate, and the garbage of different particle sizes cannot be well classified, and it is easy for larger particles to block the filter system, and smaller particles of dust cannot be filtered. Unfiltered dust is easy to adhere when passing through dust removal devices such...
