Title: Spiral wire element filter - having perforated metal sleeve with spiral groove onto which wire is wound
Inventor: BENTZ WALTER
IPC: B01D29/15
Filed: 1974-02-05
Abstract: Gas type filter consists of a wire spirally wound onto perforated metal sleeve or cylinder in which a spiral groove is cut. The gaps between the wire form filtration gaps for the liquid. The pitch of the groove can be varied and thus the degree of filtration adjusted. The wire can be in the form of a spiral spring and this can be threaded on. The groove for holding the wire or spring is cut into the upper surface of the sleeve. The filter is e.g. for filtering beer, with or without filter aid. The use of a machined groove on the cylinder means that the wire spiral can be musch more accurately and immovably located and does not have to be wound on under tension. A uniform filtration aperture is thus obtained giving more uniform filtration quality.
