Apparatus, and related method, for the recovering and the pneumatic transportation of dust coming from a filtration system

[0020] exist figure 1 In , an innovative pneumatic dust removal device for an overhead filter system 10 is designated as a whole by reference 100 .

[0021] In conventional manner, the filter system 10 comprises a filter (not shown) mounted on the upper flange 11 of a funnel 12 for collecting dust from said filter.

[0022] Such as figure 1 As shown, the funnel 12 has the shape of an inverted frustum, ie the smaller base 12A of the frustum is positioned below the larger base 12B of the frustum.

[0023] At the location of the smaller base 12A there is provided an opening (AP1) through which the dust is discharged from the funnel 12 towards the discharge means (described below).

[0024] Similarly, the upper base features an opening (AP2) which connects the filter and funnel 12.

[0025] Advantageously, said smaller base envisages a cylindrical collar 13 .

[0026] Below and around said funnel 12 there is provided an intermediate chamber 14 which also advantageously but not...
