Abstract

The invention discloses a front dust suppression mechanism of a coal conveying belt tensioning device. The front dust suppression mechanism comprises a cleaning device and a spraying device, wherein the cleaning device comprises a driving wheel, bevel gears and a cleaning belt, the driving wheel is contacted with a lower coal conveying belt and fixedly connected with one end of a horizontal drive shaft, the other end of the horizontal drive shaft is fixedly connected with a first bevel gear, the first bevel gear is meshed with a second bevel gear which is fixedly connected with one end of a vertical drive shaft, the other end of the vertical drive shaft is fixedly connected with a first driving wheel, and a second driving wheel and the first driving wheel are connected through the cleaning belt; and the spraying device comprises a water pipe and a plurality of spraying nozzles which are mounted in front of the cleaning device. The front dust suppression mechanism of the coal conveying belt tensioning device has the characteristics of simplicity, low cost and effective dust suppression, effectively reduces dust produced by the coal conveying belt at the tensioning device, does not require additional power, and is energy-saving.

Description

technical field [0001] The invention relates to the field of dust removal for coal conveyor belts, in particular to a pre-dust suppression mechanism for a coal conveyor tensioning device. Background technique [0002] At present, the most common tensioning devices of belt conveyors in China are: spiral tensioning device, vertical type, heavy hammer car type and steel rope winch type. Among them, the most commonly used is the vertical tensioning device. When the coal conveyor belt runs to the tensioning device, the belt will run vertically downward for a section. , will inevitably break away from the coal conveyor belt, and a large amount of coal dust will be generated in the process. The dust on the coal conveying belt of a coal-fired power plant seriously affects the working environment and is extremely harmful to the health of the workers. [0003] During the design and construction of the coal conveying system, the dust at the head and tail of the belt is generally noti...
