Abstract

A pneumatic dust collection system includes a housing which defines a dust-air chamber portion, a flushing air chamber portion and a clean air portion arranged one above the other. A separating wall between the flushing air chamber and the dust-air chamber is penetrated by fittings for suspending filter hoses in the dust-air chamber portions which communicate through the fittings into the flushing air chamber. A connecting tube extends from the clean air chamber into the interior of each filter hose fitting and the filter hose which is carried thereby and defines an annular flow space between the interior of the hose and the flushing air chamber. This annular flow space may be closed off by an inflatable member which is disposed at the connection of the fitting to the separating wall. At this annular space the connecting tube includes a widened portion around which the flow is diverted and which is located opposite to the inflatable membrane. The interior of the inflatable membrane is connected to an air pressure line and it is inflated to close the annular flow passage between the interior of the filter hoses and the flushing air chamber. The apparatus includes a control system for controlling flushing air to the flushing air chamber and for filling this chamber before the membrane is deflated. An over and underpressure control is connected between the clean air chamber and the dust-air chamber to maintain a selected pressure difference between the clean air chamber portion and the dust-air chamber portion during operation. The flushing air chamber and the control line for supplying the air to the chamber is closed by a rapid depressurizer member which is closed by a signal from a preferred output of a monostable fluid mechanism element. An overpressure in he flushing air chamber causes the depressurizer to open rapidly.
