Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A blast dust removal device is shown in figure 1 and comprises a blast device 2, a dust filtering barrel 5, a baffle 6, a flange 12 and the like; the dust filtering barrel 5 is cylindrical, and the top of the dust filtering barrel 5 is provided with a baffle 6; the baffle 6 is fixed with the flange plate 12 through bolts; the flange plate 12 is provided with the air blowing device 2, the baffle 6 is provided with a C-shaped hole, and the diameter of the excircle of the C-shaped hole is equal to that of the inner circle of the dust filtering barrel 5; and a rubber sealing ring is also arranged between the baffle 6 and the flange plate 12.

As shown in fig. 1 and fig. 2, the blower 2 further includes an air inlet 7, an air outlet 3, a motor 1, an impeller 9, an exhaust cavity 8, an air inlet cavity 4, an air inlet barrel 11, a partition plate 10, and the like; the air inlet cavity 4 is connected with a flange plate 12, and an air inlet 7 is arranged on the side surface of the air inlet cavity 4; the exhaust cavity 8 is positioned at the upper end of the air inlet cavity 4, and the side surface of the exhaust cavity 8 is provided with an exhaust port 3; the impeller 9 is positioned in the exhaust cavity 8; the partition plate 10 is arranged between the air inlet cavity 4 and the air exhaust cavity 8; the motor 1 is arranged on the exhaust cavity 8, and the motor 1 is axially connected with the impeller 9.
