Definitions
- the invention relates to a cleaning device comprising a pressure container, at least one cleaning container arranged therein, in which the cleaning is carried out, and means for supplying the cleaning device with a cleaning fluid, the cleaning container or containers being arranged movably to the pressure container.
- the invention further relates to a method for cleaning substrates by means of liquefied and / or supercritical gases as cleaning fluid in at least one cleaning container arranged within a pressure container, the cleaning container or containers being or being moved at least temporarily relative to the pressure container during cleaning.
- Generic cleaning devices which are used as cleaning fluid for cleaning processes with liquid or supercritical carbon dioxide, but also with any other substances or components, are usually designed for operating pressures of over 60 bar. In order to improve the cleaning result, it is necessary that a relative movement between the items to be cleaned and the
- Cleaning fluid is generated. This relative movement can be generated by moving the items to be cleaned in a cleaning drum by means of appropriate nozzle systems without this cleaning drum itself being moved.
- the cleaning drum itself in a rotational movement, so that the cleaning result can be positively influenced by the objects to be dropped.
- the rotary movement of the cleaning drum can also be carried out with a changing direction of rotation and / or rotational speed.
- the cleaning drum located in the pressure recipient or cleaning pressure container is driven via an axis or shaft penetrating the recipient, as is the case, for example, in FIG DE-A 42 30 485 is disclosed.
- this requires complex sealing or stuffing box systems, since the drive motor is arranged outside the pressure container.
- a drive by means of a rotary movement via a cleaning drum magnetically coupled to a drive motor is known, for example, from WO-A 94/01613 in connection with the cleaning of substrates by means of liquefied and / or supercritical gases as cleaning fluid.
- the present invention is therefore based on the object of demonstrating a device and a method of the aforementioned which avoid the disadvantages mentioned and provide an improved cleaning system for cleaning at different pressures.
- moving axles or shafts penetrating the pressure vessel for driving the cleaning vessel should be dispensed with and an alternative for generating the movement of the cleaning vessel by means of a magnetic coupling should be specified.
- This object is achieved according to the invention in that means for moving the cleaning container are provided within the pressure container and with the aid of these means the cleaning container or containers is or are arranged to be movable with respect to the pressure container in rotational and / or translational movement.
- This object is achieved for the method in that with the aid of means arranged within the pressure vessel for moving the cleaning vessel or the cleaning vessel without the pressure vessel penetrating, moving axes and / or without magnetic coupling of the cleaning vessel or the cleaning vessel with respect to the pressure vessel in rotation - and / or translational movement is or will be moved.
- the invention is based on the idea, on the one hand, of not using a magnetic coupling of the cleaning container to drive means due to the disadvantages described, and, on the other hand, of arranging the movement means for moving the cleaning container within the pressure container and in this way to achieve moving axes which are expensive to seal and penetrate the pressure container (Axes of rotation) can be avoided.
- the drive means are arranged inside the pressure container and thereby inside and / or preferably outside the cleaning container.
- the means for moving the cleaning container can comprise all suitable drive devices, for example hydraulic motors or electric motors, but also nozzles in connection with an impeller.
- hydraulic motors When using hydraulic motors, additional advantages can result if the cleaning fluid is used as the drive medium for the motor.
- this results in only non-moving feedthroughs for example feedthroughs for hydraulic fluid in the case of a hydraulic motor as drive means for the cleaning container, electrical lines in the case of an electric motor as drive means for the cleaning container or one or more nozzles directed to an impeller.
- the cleaning container can be designed, for example, as a cleaning drum or cleaning basket.
- the at least one supply line for filling with cleaning fluid and / or for emptying can be decoupled before moving the cleaning container or wound up when moving the cleaning container.
- the container need not of course be designed to be pressure-resistant.
- Such an embodiment of the cleaning device according to the invention should in principle also be included in the invention.
- cleaning by means of a cleaning fluid which comprises liquefied and / or above all supercritical gases cannot be carried out without pressure.
- the rotary feedthroughs previously required for the cleaning container through the pressure container can thereby be dispensed with.
- the cleaning container arranged inside the pressure container is now moved, preferably rotated. This results in a relative movement between the items to be cleaned (substrate) and the cleaning fluid, which results in the desired improvement in the cleaning effect.
- liquefiable gases can be used in particular as cleaning fluids according to the invention, for example carbon dioxide, nitrous oxide, sulfur hexafluoride or hydrocarbons such as methane, ethane, propane, ethene, propene etc., and halogenated hydrocarbons such as trifluoromethane and mixtures of the substances mentioned.
- Carbon dioxide has proven to be a particularly suitable fluid in the context of the invention, since it has particular advantages. Carbon dioxide is not flammable or explosive; large quantities of carbon dioxide are a by-product of industrial use
- thermodynamic properties of carbon dioxide suit the application as a cleaning agent. Cleaning is preferably carried out using liquefied (subcritical) carbon dioxide. This applies in particular to the cleaning of textiles, carpets and the like.
- the cleaning can take place at all suitable pressures (also above 200 bar) and temperatures.
- Cleaning is advantageously carried out at a pressure below 100 bar, preferably between 25 and 80 bar, particularly preferably at a pressure between 30 and 70 bar.
- the cleaning is advantageously carried out at a temperature between -20 and +40 ° C, preferably at a temperature between -15 and +25 ° C, particularly preferably at a temperature between 0 and +15 ° C.
- Good cleaning results could be achieved with liquefied carbon dioxide, for example at a pressure between 25 and 75 bar and a temperature between -15 and +25 ° C, in particular at a pressure between 40 and 50 bar and a temperature between +5 and +10 ° C.
- cleaning enhancers such as chemical solvents are added to the cleaning fluid.
- Chemical solvents such as surfactants, HCl, alcohols, anhydrous soaps etc. increase the solvency of the liquefied gas used as a cleaning fluid.
- mechanical abrasives such as plastic granules, steel shot or slag sand is also conceivable, in order to additionally cause mechanical removal of the surface layers of the substance to be dissolved.
- Figure a cleaning device according to the invention.
- the cleaning device according to the invention shown in the figure comprises a container or pressure container 1 - hereinafter referred to only as a pressure container - and a cleaning container 2 arranged therein and designed to be movable in a rotational and / or translational movement.
- the material (substrate) to be cleaned is introduced into this .
- the goods to be cleaned can be both bulk goods, textiles, carpets or the like as well as industrial parts such as workpieces, machine components, assembly groups etc.
- the cleaning device according to the invention is filled and emptied via at least one access opening, not shown in the figure, which is to be provided with a corresponding seal for cleaning processes which run under pressure.
- the cleaning fluid is fed to the cleaning device according to the invention via a feed or supply line, not shown in the figure. It comes from a storage and / or storage container, for example.
- this feed line can have a coupling, in particular a quick-action coupling.
- the desired amount of cleaning fluid is supplied via the supply line.
- the feed line is then disconnected, for example.
- the feed line has a winding device.
- a winding mechanism enables the cleaning container 2 to make a certain number of revolutions - this is limited by the line length - in each direction without the supply line having to be uncoupled.
- the cleaning container 2 lies - according to a possible embodiment of the invention - with two rollers 4 and 4 'on corresponding roller conveyors 3 and 3'. These roller conveyors can now be moved or driven by means of a drive device, for example by means of a hydraulic motor 5, which results in a rotary movement of the cleaning container 2.
- the hydraulic motor 5 drives a gearwheel 8, which in turn sets the cleaning container 2 in a rotational movement via a toothed ring 9 arranged over the circumference of the cleaning container 2.
- a drive medium is supplied or discharged to the hydraulic motor 5 via the lines 6 and 7.
- the passages (leadthroughs) of these lines through the pressure vessel 1 are to be designed according to the use of the cleaning device according to the invention.
- Suitable drive media for such a hydraulic motor 5 are, for example, oil, water or corresponding special liquids.
- the direction of rotation of the hydraulic motor 5 is reversed by reversing the direction of flow of the drive medium.
- the rotational movement of the cleaning container 2 achieved in this way can also be maintained during the filling and emptying of the cleaning device according to the invention.
- the cleaning fluid can also be used as the drive medium for the hydraulic motor 5.
- the cleaning container 2 - preferably arranged over its circumference - can have at least one impeller 13 which is coupled to a drive device, such as, for example, at least one nozzle directed towards the impeller 13.
- the impeller 13 is preferably designed as a so-called pellet turbine.
- a drive medium is fed into the pressure vessel 1 via a line 11 and directed at the impeller 13 by means of at least one nozzle (not shown in the figure) such that the impeller 13 and thus the cleaning vessel 2 are set in motion.
- the direction of rotation can be reversed achieve that the orientation of the nozzle is changed or several nozzles with different orientations are provided
- the cleaning fluid can be withdrawn from the pressure vessel 1 via a relaxation device 14, which also drives the impeller 13, and a discharge line 15
- the cleaning container 2 can have internals which influence the movement of the items to be cleaned.
- Such internals can, in particular, whirl the cleaning fluid, thereby increasing its cleaning effect
- the cleaning container 2 is designed to be removable from the pressure container 1. This enables drafty emptying and refilling, particularly in industrial applications of the cleaning device according to the invention
- the possible types of movement of the cleaning container 2 can be multiplied by mounting the cleaning container 2 on cams and / or by means of corresponding, for example hydraulically operated lever mechanisms.
- cams and / or by means of corresponding, for example hydraulically operated lever mechanisms By means of such configurations, as with the superimposition of transverse and / or longitudinal movements, three-dimensional movement sequences of the cleaning container 2 and thus also of the items to be cleaned are possible.
- the pressure vessel 1 is preferably cylindrical, barrel-shaped or spherical.
- the last two options mentioned can be regarded as particularly low-voltage and allow minimal wall thicknesses for the container or recipient.
- the cleaning device enables cleaning processes to be carried out using a wide variety of pressurized cleaning fluids, such as, for example, liquid or supercritical carbon dioxide, with the required technical outlay being limited.
- a targeted and optimized movement of the items to be cleaned can now be achieved without a rotary feedthrough.
- the energy expenditure required for the rotary movement is reduced.
