Definitions
- Liquid separator especially for cleaning crankcase gases, with a separator cartridge
- the invention relates to a liquid separator, in particular for cleaning crankcase gases according to the preamble of claims 1 and 12.
- the invention relates to a separator cartridge which is suitable for installation in the above-mentioned liquid separator, according to the preamble of claim 11.
- An oil separator in which an exchangeable separating cartridge is used, is e.g. B. known from DE 196 45 666 A1.
- the separation cartridge is installed in a housing such that a seal between the raw and clean side, i.e. H. between oil-containing and almost oil-free air, so that the gas stream to be cleaned must flow through a separation area of the separation cartridge.
- the separated liquid can leave the housing through an outlet.
- the separating cartridge can be replaced if contaminants in the gas flow have added the separating material to the cartridge and the pressure loss generated by the cartridge thus increases too much. Since the separating cartridge is a replacement part, the economic efficiency of the liquid separator depends to a large extent on the costs for the replaced separating cartridges. Therefore, the separating cartridge, which is proposed in the above-mentioned document, is simply constructed. It consists of one cup-shaped carrier around which the separating material is wrapped. However, this simple structure also has disadvantages. The winding of the separating material on the carrier can lead to leaks in the front edge areas. In addition, the separating cartridge or the associated receptacles in the housing of the liquid separator must be provided with seals in order to ensure that the assembly functions properly. This reduces the economy, which is aimed for by the simple construction of the separating cartridge. Otherwise, the reliability of the separating cartridge must be compromised.
- the object of the invention is therefore to provide a separating cartridge of simple construction, which is inexpensive to manufacture and at the same time ensures high component reliability.
- This object is solved by claims 1 and 12.
- a separating insert is claimed according to claim 11, which is suitable for installation in the liquid separator according to the invention.
- the liquid separator according to the invention has, in a known manner, a housing which can be closed by a cover. Corresponding connections enable the gas to be cleaned to be passed through and the separated liquid to be discharged.
- a separating cartridge is used in the liquid separator, which has a separating means for separating the liquid and a supporting means for ensuring the dimensional stability of the cartridge.
- the separating cartridge is constructed in such a way that it has an end plate on at least one of its end faces, which corresponds to the associated receptacle in the housing in a sealing manner. It is also possible for the end disks to be fixedly attached to the support means, a seal being formed between the end disc and the support means. This saves seals for installing the cartridge in the housing.
- separating materials can be used as separating agents.
- Materials that can be wrapped around the support means, which is preferably tubular, are particularly suitable.
- the separating means can in particular consist of a yarn winding.
- the primary function of the separating agent is to separate a liquid phase from the gas phase. This is collected and discharged from the separator arrangement using a drain. However, the separating agent also serves to retain particles that are in the gas to be cleaned. These remain in the separator and are therefore the lifespan of the separator cartridge. In order to extend the service life, a further separation stage can be provided, which is primarily suitable for separating the particles.
- the fluid can also be separated in several stages.
- the support means can take on an additional separation function. This can e.g. B. from a porous material for separating the finest liquid droplets from the gas phase.
- the separating cartridge is designed to be metal-free. There are significant advantages for the disposal of disused cartridges, since they can be used for thermal recycling.
- Another possibility is to manufacture the end plate from a multi-component plastic.
- foams which expand similarly to the end plate made of nitrile rubber and thereby produce a connection with separating and supporting agents.
- Another possibility is to provide the end face regions of the separating and / or supporting means with a particularly liquid component and to bring them into connection with the other, preferably stronger, component, as a result of which the end disk is cured with a certain residual elasticity.
- Another possibility is the use of elastic end plates which are connected to the end faces of separating / supporting means, e.g. B. by gluing.
- the end plate can also be produced in one piece with the support means.
- the support means In this way, a basic body is created that is comparable to the construction of a spool of thread.
- the separating means can be wrapped around this.
- the bond between the end plate, support means and separating means can also be sealed by compressing the same in this area.
- the compression of the separating agent can by various means such.
- B. a Kabeibinder can be reached, which is wrapped around the separator and tightened. Instead of the cable tie, a thread can also be woven into the fleece.
- the proppant itself must be gas permeable.
- the cylindrical separation cartridges have two faces. It makes sense to provide both end faces with the same end plates. Depending on the application, a different design can also be selected.
- the receptacle in the housing of the liquid separator for the separating cartridge advantageously has detents which are suitable for fixing the separating cartridge. These can e.g. B. consist of locking lugs that are attached to a cylindrical neck. The separating cartridge is pushed onto this until the latches protrude below one of the end plates.
- the surface pressure generated by the inherent elasticity of the end disks, which achieves the sealing effect can also be used as a non-positive connection between the receptacle and the separating cartridge. Another possibility would be the arrangement of a bayonet lock.
- the receptacle for the separating cartridge is designed as a nozzle, this must be made gas-permeable in the area between the end plates of the separating cartridge in order to allow the gas to be cleaned to be passed through.
- the nozzle can also perform certain separation functions. This is particularly possible if the gas to be cleaned is to be passed through from the inside to the outside. The latter then first passes through the nozzle, whereby the fluid to be separated can be pre-separated, and then passes through the separating material of the separating cartridge.
- the connecting piece used can have a return valve for separated liquid.
- the return valve is closed while the separator is operating. This avoids bypassing the separator due to unpurified gas.
- the return valve opens so that the separated fluid can be discharged from the nozzle.
- the nozzle can advantageously be made in one piece with the cover of the housing. In order to facilitate the casting of the individual parts, they can be manufactured individually and afterwards, in particular by a The welded connection must be firmly connected.
- the advantage of the one-piece design is the saving of a seal.
- a separating cartridge according to claim 11 is characterized in that it is suitable for installation in a liquid separator according to the invention.
- this separating cartridge can also be used without a housing at installation locations where liquid separation from a gas phase is required in a closed system. This is e.g. B. required in the oil circuit of an internal combustion engine. The resulting crankcase gases must be discharged from this system, whereby the most complete possible oil removal is necessary.
- a cover-socket combination can be used according to claim 10.
- the separating cartridge can also be integrated in an oil filter module.
- FIG 1 shows the arrangement of the separation cartridge according to the invention
- Figure 2 shows the arrangement of a separating cartridge in a crankcase in the
- the liquid separator shown in FIG. 1 has a housing 10, into which a cover 11 is inserted using O-rings 12.
- a receptacle 13, designed as a socket, for a separating cartridge 14 is welded to the cover 11.
- the dash-dotted arrows indicate the direction of flow of the gas to be cleaned. These flow through an inlet 15 into the housing 10. They pass through the separating cartridge 14 and the receptacle provided with passages 16 and thus reach a clean side 17 of the liquid separator. Then leave the liquid separator through an outlet 18.
- the outlet 18 is provided with a vacuum valve 19. This is necessary when using the liquid separator as an oil separator for crankcase gases if these are fed to the intake tract of the internal combustion engine. If the negative pressure prevailing in this area becomes too large, the valve closes, thereby preventing excessive production of biow-by gases in the crankcase.
- the liquid is mainly separated in a fleece 20 of the separation cartridge 14. From there it drips back into the housing 10 and leaves it through an outlet 21, which leads back into a crankcase, not shown. However, certain amounts of liquid can also be separated in a support means 22 and in an area 23 of the receptacle provided with the passages 16. These collect on the clean side 17, which is formed by the nozzle.
- a return valve 25 is therefore arranged in a nozzle base 24. This consists of a valve seat 26 and a valve plate 27 which has cutouts 28 at the edge.
- the return valve 25 opens, so that the oil can flow past the valve seat 26 through the recesses 28. This is e.g. B. when the engine is stopped and is indicated by dashed arrows. If the pressure equilibrium is reversed when the engine is operating, the valve plate 27 presses against the valve seat 26, as a result of which a bypass flow of gas to be cleaned is avoided by the return valve (cf. illustration according to FIG. 2).
- the separating cartridge 14 consists of the cylindrical and gas-permeable support means 22, on which the fleece 20 is wound. End faces 32 of these two components dip into end plates 33, which, for. B. can be produced in two-component technology and assemble the separating cartridge 14 to form a firm bond.
- the end disks 33 are designed to be elastic in the radial direction. If the separating cartridge 14 is pushed onto the receptacle 13, a sealing, tight fit results between these components due to the radial widening of the end disks. The separating cartridge is fixed in its assembly position by this non-positive connection.
- FIG. 2 shows an oil separator which is installed in an installation opening 34.
- the installation opening belongs to a crankcase 35 of an internal combustion engine, not shown.
- the raw side 29 is thus formed by the interior of the crankcase 35. Accordingly, the arrangement of a drain 21 and an inlet 15 is omitted.
- the lid 11 is constructed except for the receptacle 13 in accordance with FIG. 1. However, the receptacle 13 is adapted to the different design of the separator according to FIG. 2.
- the separating cartridge 14 has support means 22a and end plates 33a which are made in one piece from plastic, in particular by injection molding.
- the fleece 20 is wound onto the resulting unit and additionally fixed or compacted by gluing 36 in the area of the end plates 33a. Compression of the fleece is also sufficient to prevent a bypass flow of the air to be de-oiled, bypassing the fleece.
- the compaction of the fleece can also be done mechanically, e.g. B. done by a cable tie 41.
- the connecting piece base 24 adjoins the lower end disk, and the upper end disk carries an extension 37 which corresponds to the receptacle 13. The approach and the top End disks have the same outside diameter.
- the separating cartridge 14 is inserted with the upper end plate into the receptacle 13 until latching lugs 38 snap into the underside of the upper end plate. As a result, the separating cartridge 14 is axially fixed in cooperation with a shoulder 39.
- the radial seal between the receptacle 13 and the end plate is brought about by a fit and can be supported by an additional seal 40, which can be accommodated in the cover 11 or in the extension 37, as the detail in FIG. 2 shows.
