Abstract

The invention discloses a mine ventilation device with a dust removal function. The mine ventilation device comprises a shell, a motor, fan blades and an exhaust port. An air inlet is formed below theleft end of the shell, a rotating shaft is arranged above the air inlet, the rotating shaft is hollow, a nozzle is fixedly connected to the lower end of the rotating shaft, the motor is arranged inside the shell, a driving shaft is fixedly connected to the left shaft stretching end of the motor, the fan blades are distributed on the driving shaft, a crankshaft is arranged at the right side of themotor, a cloth bag support is arranged at the right side of the crankshaft, a cloth bag assembly is installed inside the cloth bag support, a connecting rod sleeves the shaft neck of the crankshaft,the right end of the connecting rod is hinged to the cloth bag assembly, water inside a water tank is conveyed to the nozzle through a water pump, the nozzle rotates while spraying is performed, the spraying range is enlarged, the spraying process is more uniform, preliminary dust removal is performed on air entering the shell, the air is filtered by means of the cloth bag assembly, meanwhile, thecloth bag assembly moves left and right, dust attached to the cloth bag assembly is shaken off, and the trouble caused by manual cleaning of the cloth bag assembly is omitted.

Description

technical field [0001] The invention relates to a fan, in particular to a mine ventilation device with dust removal function. Background technique [0002] Fans have a long history. More than 2,000 years ago, China, Babylon, Persia and other countries used ancient windmills to raise water for irrigation and to grind grain. After the 12th century, windmills developed rapidly in Europe. China had already produced a simple wooden hulling windmill before BC, and its working principle is basically the same as that of a modern centrifugal fan. [0003] Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Grain drying and selection, wind tunnel wind source and inflation and propulsion of hovercraft, etc. Mine fan is a kind of axial flow fan. Because of ...
