Embodiment Construction

[0012] The dust separator shown in the figures comprises a cyclone 1 having an upper substantially cylindrical part 1.1 and a lower substantially conical part 1.2 with a lower opening 1.3. Furthermore, the cyclone 1 has a horizontal partition wall 1.4, which is arranged slightly lower in the substantially cylindrical part 1.1, forming an upper chamber 1.5 and a lower chamber 1.6 in the cyclone 1 .

[0013] Two conical filters 2 are arranged in each opening of the partition wall 1 . 4 and are held in this opening by means of each cover 3 . Each cover 3 in turn has an opening 3.1 which can be closed or opened by means of a valve disc 3.2 which remains coupled via a rod 3.3 to a compressed air cylinder 3.4 arranged to descend to the respective filter device 2. exist figure 1 In , it is shown that the left valve disc 3.2 is in the closed state, while the right valve disc 3.2 is in the open state. Also shown in dashed lines is the left valve disc 3.2 in the open state and also i...

Abstract

The present invention relates to a dust separator, comprising a cyclone (1), which supports at least one fan (5), by means of which dust- mixed air is sucked into the cyclone (1) through at least one suction opening (7) and is brought to pass one or more shell-shaped filters (2) before the cleaned air is blown out through at least one exhaust opening (5.4), the cyclone (1) being divided into an upper room (1.5) and a lower room (1.6) by a partition wall (1.4), in which the respective filter (2) is arranged, projecting down into the lower room, at least one clean blowing device being arranged to blow compressed air from behind through the respective filter (2) when the same has become clogged by dust. The filters (2) are covered by at least one lid (3), which has at least one opening (3.1)for the respective filter (2), in which at least one valve device (3.2, 3.3, 3.4) for cleaned air is arranged. Said at least one lid (3) supports at least one clean blowing nozzle (6), which mouths on the underside of the lid (3), and the clean blowing nozzle (6) stands in communication with at least one source of compressed air via at least one pilot valve (6.2).

Description

technical field [0001] The present invention relates to a dust separator, preferably for cleaning air from dust during rock drilling and similar activities and comprising a cyclone supporting at least one fan, the dust-laden air being blown by means of The at least one fan is drawn into the cyclone through at least one suction opening and causes dust-laden air to pass through one or more shell-shaped filters before the cleaned air is blown out through at least one discharge opening, said The cyclone is divided into an upper chamber and a lower chamber by a partition wall in which the individual filters are arranged extending downwards into the lower chamber, at least one cleaning blowing device being arranged for when the respective filter has started to become clogged with dust Blow compressed air from the rear through the corresponding filter. Background technique [0002] Dust separators of the above-mentioned type are known from European patent specification 0841095, wh...
