Problems solved by technology

Although such a filter device is simple to manufacture and facilitates flow, the clamping and fastening of the filter hose on the sleeve is time-consuming.
[0007] Filter devices of this type consisting of filter sleeves with pre-produced adapter flanges for finished filter elements have also been unsuitable up to now

Embodiment Construction

[0019] From figure 1 It can be seen that the filter device has a plate-shaped filter holder 12, the size of the filter holder 12 can be any, and it has at least one through hole 11, the edge of the through hole 11 is formed by a neck-shaped protrusion 13 is formed, and the protrusion 13 is configured in the embodiment shown as a substantially cylindrical flange (Kragen) that can be molded upwardly. Other flange forms and implementations consisting of multiple parts such as protrusions that can be welded to each other and filter retention are practical within the framework of the present invention without limitation.

[0020] The filter element 14 suitable for the type and shape of the material is closely connected with the adapter flange 15 on the mouth edge of the adapter flange 15. Viewed in cross section, the adapter flange 15 has two branches in the illustrated embodiment, namely a branch 15A parallel to the plate and a branch 15B parallel to the protrusion. The two branches...

Abstract

The invention relates to a filter arrangement comprising a plate-shaped filter holder (12) provided with at least one stem-type protruberance (13) having an opening (11), said filter holder (12) being used to receive a filter element (14) in a sealed manner for each protuberance on the raw gas side of the filter holder. In order to ensure that the filter is changed easily with sufficient filtering safety, each filter element (14) is provided with an adapter collar (15) comprising at least one limb (15B; 15D) parallel to the protruberances. Said limb can be placed, from the raw gas side, inside or over the protruberance. A sealing arrangement (16) provided comprises sealing elements (16A, 16B) which are parallel to both the plates and to the protruberances and are used for the at least partial join between the protruberance and the adapter collar.

Description

Technical field [0001] The present invention relates to a filter device according to the preamble of claim 1, that is, the following filter device in which a plate-shaped filter holder is released in each through hole There is at least one neck-shaped protrusion underneath, and a filter sleeve (Filterkerze) is allocated to the through hole. Background technique [0002] The filter elements that can be assembled as parts in the required number or into the filter device are usually sealed and screwed to a plate-shaped filter holder, for example according to DE203 12074 U1 figure 1 . [0003] A typical application of this type of filter device is so-called vacuum conveying equipment, as they are disclosed by DE 203 12 074 U1 and they have a collection container for conveying goods sucked in under vacuum. There is the negative pressure of the vacuum pump at the collection container and the conveyed goods are deposited on the bottom of the collection container under the action of gravi...
