Abstract

The double filtration system is a variable apparatus which permits fractionated filtration for the first time by means of the direct successive connection of a fixed and an exchangeable plate. Apart from glass, other materials having pore channels, such as for example teflon or steel, are also used.

Description

Doppel-Filtrations-Sys em Double filtration sys em

Bisher bekannt sind Glasgeräte zum Filtern wie beispielsweise Filtertiegel, Filtertrichter und Filternutschen. Dabei besteht das eigentliche Filterelement aus einem gesinterten Glaskörper, meistens aus einer runden, eingeschmolzenen Glasscheibe in den Porositäten oo bis 5. Weiterhin bekannt sind Xunststofffiltriergeräte mit wechselbarer Filterplatte solrie Glas/Kunststoff Filter mit wechselbarer Filterplatte au. Metall oder Glasgries.So far, glass devices for filtering such as filter crucibles, Filter funnels and suction filters. The actual filter element consists of a sintered glass body, usually made of a round, melted glass pane in the porosities oo to 5. Also known are plastic filter devices with exchangeable filter plate solrie glass / plastic filter with exchangeable filter plate ouch Metal or glass grit.

Bei manchen chemischen Trennungsvorgängen ist es erwünscht, zuerst grobe Kristalle von dem feinen N ederschlag abzutrennen.In some chemical separation operations, it is desirable to go first to separate coarse crystals from the fine deposit.

Dazu benötigte man bisher zwei Filtrationsvorgänge mit zwei Filterelementen wie beispielsweise zwei Nutschen mit den Porositäten o und 4 oder beispielsseise ein Wechselplattensystem mit zwei Wechselplatten in den Porositäten o und 4.Previously, this required two filtration processes with two filter elements such as two nutsches with porosities o and 4 or for example an exchangeable plate system with two exchangeable plates in porosities o and 4.

Bisher fehlt die Möglichkeit, in einem Arbeitsgang fraktioniert zu filtrieren. Die nur n@u eniwickelte Toppelfilterserie stellt in der rpat einen entscheidenden technischen Fortschritt dar. Das hier vorgestellte System verbindet Wechselplatte, Schraubfilter system und die Wahl, sowohl mit alten Saugflaschen und Gukko zu arbeiten als auch mit modernen Saugflaschen mit IS0-Gevinde.So far there has been no possibility of fractionating in one operation filter. The newly developed canister filter series represents a decisive factor in the rpat technical progress. The system presented here combines removable disk, Screw filter system and the option to work with both old feeding bottles and gukko as well as with modern feeding bottles with IS0-Gevinde.

Claims

P a t e n t a n s p r ü c h e 1. Double filtration system by means of sintered special glass, preferably ROBU glass, which is specially designed for fractionated Filtration of two filter elements, particularly preferably round filter plates in one contains certain porosity sequence.

2. Double filtration system according to claim 1.), d a d u r c h g e k e n n shows that the upper filter plate is firmly melted down while the second plate, a plate that can be changed, offers the possibility of directly after coarse filtration in the upper filter carry out a fine filtration in the second filter, wherein the The second plate has to work as a removable plate with porosities from oo to 5.

Double filtration system according to claims 1.) and 2.), characterized in that you can use both plates separately that the filter plates both as sintered glass grit made from borosilicate 3.3 and from an alternative material can be made, the materials Teflon and steel on top.
