Ein Filter 1, ausgebildet und eingerichtet zum Einfügen in eine Absaugeinrichtung, umfasst ein Filtergewebe 15 und einen Filterkörper zur Aufnahme des Filtergewebes 15, wobei der Filterkörper ein als Hohlkörper mit mindestens zwei Öffnungen ausgebildetes Filtergehäuse 2 mit einem Schlauchanschlussabschnitt 3 an einer ersten Gehäuseöffnung und mit einem Eingangsabschnitt 5 an einer zweiten Gehäuseöffnung umfasst. Ferner ist das Filtergewebe 15 sackförmig ausgebildet, die offene Fläche des Filtergewebes 15 beträgt mindestens das Doppelte der Fläche des Querschnitts des äußeren Endes des Schlauchanschlussabschnitts 3 beträgt, das Filtergewebe 15 umfasst Abschnitte mit einer Maschenweite w von 10 bis 80 µm umfasst und der Fadendurchmesser d der Fäden dieser Abschnitte des Filtergewebes 15 beträgt von 10 bis 80 µm.
摘要:
The invention relates to a cyclone (10) having a simple construction and nevertheless good efficiency for separating non-gaseous constituents and gaseous constituents of a mixture. Said cyclone has an upper separating section (18, 20) and a lower collecting section (22) for non-gaseous components. A separating plate (62) is arranged between said two sections such as to be inclined obliquely and is spaced apart from the open end of an air discharge pipe (38) but overlaps said air discharge pipe in the radial direction.

The invention relates to a device (10) for precipitating suspended materials from a liquid, in particular for precipitating gypsum from water, having a vessel (12) comprising a liquid inlet (22) and a liquid outlet (26), and subdivided into chambers (40, 42, 44, 46) that are in sequence in the flow direction by means of partitions (32, 34, 36, 38), wherein the liquid inlet (22) opens into a first of the chambers (40) and wherein the liquid outlet (26) opens into a last of the chambers (46). According to the invention, at least one part of the chambers (40, 42, 44, 46) and preferably every chamber (40, 42, 44, 46) communicates with the chamber (42, 44, 46) downstream thereof in the flow direction by means of an opening (54) in the partition (34, 36, 38) disposed between the chambers (40, 42, 44, 46), wherein the opening (54) extends at a distance from and parallel to an upper edge (48) of the partition (34, 36, 38), and each of the openings (54) is disposed at a greater distance from the vessel floor (15) than the opening (54) in the partition (36, 38) downstream thereof in the flow direction.
摘要:
A filter cartridge (10), which is suitable in particular for cleaning dental wastewater, has a housing (32) with three different chamber regions which accommodate three different filter materials (52; 44; 80), which have different filter properties. A sedimentation chamber (48, 50) is arranged upstream of the first filter material (52).
摘要:
A strainer / filter unit for effectively collecting solid, liquid or gaseous substances at the source and the method of using the strainer / filter unit. The strainer / filter unit includes a housing, a one-way valve at one end of the housing, and a filter having a certain depth and thickness within the housing. The filter is formed from a plurality of layers of material with pores such that pores of one layer partially overlap pores of subsequent adjacent layers. Matters entering the strainer / filter unit are collected in the filter while travelling through filter via a tortuous path.
摘要:
Water separator for continuous separation of water, air and particles, said separator comprising an inlet pipe (18) for receipt of a mixture of water, air and particles simultaneously from several sources such as dental surgeons etc. an outlet pipe (22) being connected to a suction motor (23), an upper chamber (2) being connected with a lower chamber (3) by a valve (17) in the bottom of the upper chamber (2), the lower chamber (3) normally being closed by a check valve (8) in the bottom, a three- way valve (24) located in an air connection pipe (20) being adapted to establish a connection between the upper (2) and lower (3) chambers in a first position and closing said connection to the upper chamber and allowing atmospheric air to enter into the lower chamber (3) in a second position, and the upper chamber (2) comprising a coarse filter (4) capturing particles from the liquid flow to the lower chamber (3), where the water separator comprises two tanks, a main tank (1) and a safety tank (11), which are connected through a connection pipe (19) from the upper chamber (2) in the main tank (1) to the safety tank (11) and through the air connection pipe (20) from the lower chamber (3) in the main tank to the safety tank (11), that the inlet pipe (18) is through the lid of the main tank (1), that the outlet pipe (22) is through the lid of the safety tank (11), and the safety tank (11) normally being closed by a check valve (15) in the bottom.
