Description
Technical field
The utility model belongs to mining machinery applied technical field, is specifically related to a kind of cleaning type concrete sprayer.
Background technology
Along with the increase of present various pollutions and noxious emission, the improvement of atmosphere pollution is become to social development major issue, wherein concrete ejection supporting technique is also to cause one of pollution sources that atmosphere pollutes. Concrete ejection supporting technique, through the development of decades, is generally applied in the Rock Workings Support of building foundation pit, subway, bank protection, highway, high ferro tunnel and mine engineering. At present, concrete support technological development is dry spray and two kinds of processes of wet shot. Concrete spraying technique is substantially without dust emission, also less on environment and human body impact, but because wet spraying process complexity, fed distance is short, plant maintenance cleaning is loaded down with trivial details, and need to be equipped with large-scale concrete-agitating, transporting equipment, mainly in the construction of high ferro, freeway tunnel, applies at present more, but in the Rock Workings Support of building foundation pit, subway, bank protection and mine engineering, cannot apply, what during the concrete of these occasions sprays, also mainly adopt is dry pressure spray process.
