Definitions
- the invention relates to a cyclone Centrifugal separator for separating solid materials or of liquids from gases or from liquids, at the swirl chamber there is a tubular outflow channel connects.
- Cyclones of the aforementioned type occur in the swirl chamber and also in the adjoining tubular Abströmkanal a significant wear. This wear leads to very rapid destruction of the cyclone, so that within a relatively short Intervals of the vortex chamber or the entire cyclone need to be replaced. This results very much frequent downtimes for the systems concerned, which cause considerable costs.
- Cyclones are already known, with those that are special parts exposed to heavy wear from one abrasion-resistant material are made. Hereby the service life of the parts in question is somewhat extended and therefore downtimes are also increased of the facilities slightly reduced. But since the concerned Parts are still subject to wear and tear furthermore, the non-abrasion-resistant material manufactured parts replaced from time to time are still considerable downtimes of the plants.
- the invention is based, which in the known cyclones wear significantly reduce and thereby downtimes of the cyclones to largely exclude the contained systems.
- cyclone of the type mentioned at the beginning the inside surfaces of the swirl chamber and the inside surfaces of the tubular discharge channel of the cyclone from a powder metallurgy sintered hard material are formed.
- hard materials come for example titanium carbide, Titanium nitride, titanium diborite, zirconium carbide, zirconium imiboride, Niobium carbide, tantalum carbide, chromium carbide, chromium boride, Molybdenum silicide and tungsten carbide - with one Binder, for example nickel or cobalt - in Consideration.
- Binder for example nickel or cobalt - in Consideration.
- the Carbides too.
- Metallic or non-metallic hard materials of the aforementioned Kind indicate with regard to wear due to abrasion - as occurs with cyclones - very good Properties on and can be practically in any Form are made.
- inventive Cyclones are all affected by the swirl and thus protected parts exposed to high wear.
- a tight connection between the tubular Outflow channel and the molded part made of metallic or non-metallic hard material for example achieved that the tubular discharge channel, which is generally made of steel, on the molded part shrunk from metallic or non-metallic hard material.
- the inner surfaces of the Vortex chamber and the inner surfaces of the tubular outflow channel of the cyclone by hard phase diffusion hardened or by deposition of hard material phases coated.
- This will wear resistance Inner surfaces of the swirl chamber and the inner surfaces of the Outflow channel significantly increased.
- This configuration of the Cyclones according to the invention are particularly expedient if the wear occurs particularly large is, for example, if in the to be separated Mixture of sand is included.
- the entire Vortex chamber and / or the entire outflow channel from one metallic or non-metallic hard material.
- a higher proportion of hard material needed to manufacture such a swirl chamber and / or such an outflow channel is proportionate inexpensive. They can also completely turn off metallic or non-metallic hard material Parts have a considerably smaller wall thickness.
- the cyclone according to the invention can still be improved that the vortex chamber and the tubular outflow channel connected to one another by connecting elements are. This enables simple and quick installation and removal of the cyclone.
- the swirl chamber is expediently made of at least two sections formed by fasteners are interconnected. This can result in certain Cases - depending on the purpose of the cyclone - the Production of the swirl chamber can be facilitated.
- tubular outflow channel from at least two Parts formed by connecting elements with each other are connected.
- sections easier to manufacture than a complete outflow channel, on the other hand, they are easier to use and can therefore by hand without special aids brought and installed in the relevant place.
- connection elements Steel are formed.
- Such connecting elements are both inexpensive to manufacture and sufficient stable.
- connection elements are designed as screw connections are. Screw connections can be loosened easily and also easily reconnect.
- the connecting elements can be glued or soldered with the vortex chamber or its sections and the tubular discharge channel or its sections connected his.
- a preferred embodiment of the invention is that the fasteners on the vortex chamber or its sections and on the tubular drainage channel or its sections shrunk are.
- the connecting elements made of plastic.
- the connecting elements are designed as sleeves, the overlap the respective connection point, the For example, the sleeve is fastened with an adhesive can be.
- the connecting elements can also consist of a tape soaked in plastic, the before the plastic is crosslinked to the respective one Connection point is applied and that after curing of the plastic forms a firm association.
- At least the tubular one Drain channel provided with reinforcement.
- This reinforcement can from a on the tubular discharge channel pushed-on pipe made of metal, for example aluminum consist.
- a plastic layer is particularly useful formed reinforcement.
- Such reinforcement can be pushed onto the tubular discharge channel Plastic pipe consist of or with a Plastic-impregnated tape or one with plastic soaked mat.
- the tape or mat are in front of the Networking of the plastic on the tubular discharge channel applied and form after curing the Plastic a solid layer.
- Another useful reinforcement is through a rubber layer educated. This reinforcement can either be made one pushed onto the tubular outflow channel Rubber tube can be formed or it can be a rubber layer applied to the parts to be reinforced and then vulcanized.
- the cyclone shown in Fig. 1 consists of a Vortex chamber 1 and a tubular outflow channel 2, which are interconnected by connecting elements 3 are.
- the swirl chamber 1 has a cylindrical part 4 and a conical part 5.
- In the conical part 5 is one of a metallic or non-metallic Hard material formed funnel-shaped insert 6 used.
- the cylindrical part 4 of the swirl chamber 1 and the tubular outflow channel 2 consist entirely of a metallic or non-metallic hard material.
- the tubular outflow channel 2 consists of the two Parts 7 and 8, which are connected by connecting elements 9 are interconnected.
- a cyclone which consists of a Vortex chamber 11 and an outflow channel 12 exists.
- the tubular outflow channel 12 has the two sections 17 and 18 on, by connecting elements 19 together are connected.
- the vortex chambers can be very different be designed.
