Definitions

  • the invention relates to a method and an arrangement for the spot-free removal of liquid adhering to the material to be treated by means of compressed air jets.
  • the task is to carry away as little treatment liquid as possible when transporting the material from one treatment bath to the next.
  • the liquid that adheres to the surface of the material to be treated must be removed from the bath after removal.
  • the material to be treated must be completely dry.
  • this drying must also take place without stains.
  • the adhering drops have a particularly disadvantageous effect if, for technical or decorative reasons, a completely stain-free good is to be produced, because an evaporating water drop always leaves a visible stain on the surface of the treatment good.
  • DE-AS 24 05 870 proposes a dryer for ceramic moldings, in which the moldings which are guided in a meandering manner through the dryer space are dried with heated air from air distributors arranged one behind the other in the conveying direction and rotating or oscillating about their axis.
  • the moisture must not only be removed from the surface of the moldings, but in particular from the interior thereof. Therefore, the parts must be dried gently and slowly. This will include also causes the heated air from the air distributors to be blown into the dryer room as evenly as possible and only intermittently sweeping over the moldings in order to give further moisture inside the moldings the opportunity to reach the mold surface.
  • the evaporation of the adhering moisture requires considerable energy expenditure.
  • Blow-off devices such as, for. B. nozzle sticks, which are arranged on the baths.
  • the material to be treated is guided past the nozzle sticks and blown on.
  • motor-driven blowing devices are guided past the material there several times.
  • EP 0 205 819 A1 describes a method and a device for the spot-free drying of objects with surfaces wetted by liquid, the object being introduced directly and quickly into a gaseous treatment medium after immersion in the bath and simultaneously or subsequently with is blown onto the gaseous treatment medium in order to blow off the treatment liquid wetting the surface.
  • the process is only suitable for small quantities of parts to be treated, since these are removed from the treatment bath in successive process steps, blow-off nozzles are then brought into the position aligned with the part to be dried and the adhering liquid is removed.
  • different constructions of the otherwise complex treatment device are required.
  • EP 0 486 711 A1 describes a method and a device for blowing off a liquid from an object, wherein a large number of high-frequency pulsating, sudden impacts of at least approximately parallel pressure jets against the object directed to drive the liquid away.
  • the process should also be suitable for spot-free drying without the use of solvents.
  • the nozzle sticks used for air blowing are guided past the goods.
  • a microprocessor controls solenoid valves that interrupt the air flow in quick succession. This creates pulsating air blasts that crush or destroy the adhering drops on the material to be dried.
  • the disadvantage of this method is that the air blasts on each side of the product carrier always hit the material to be dried from only one direction.
  • the goods would therefore have to be plate-shaped in order to be able to reach all surface areas.
  • the parallel jets from the nozzle sticks only reach a part of the surfaces to be treated, but not undercuts and depressions, so that spot-free drying in these surface areas is not possible. Therefore, the drying times in such cases become uneconomically long and the air consumption becomes too high.
  • the valve control used in such a device is complex and expensive.
  • DE 39 20 955 C1 discloses a method for ventilating dry material passing through a dryer by means of an air circulation device with fans which can be rotated about their vertical axis and are arranged one behind the other, in which all fans rotate at a coordinated rotational position and corresponding speed.
  • the liquid adhering to the material to be treated is blown from one side of the parts to the other as it passes through the drying installation, so that a very sharp jet of air is required in order to be able to achieve reasonably satisfactory drying results.
  • the compressed air jets only drive the liquid drops on the surface of the item to be treated, so that the blowing of the drops only temporarily displaces the drops to a place of the item to be treated which is protected from the air jet, but does not remove the drops as quickly as possible. It also becomes one of the air jets facing side of the material to be treated only caught by the air jets during half the treatment time. During the second half, the air jets are not directed towards this side and therefore do not cause the intended drying on this side.
  • the present invention is therefore based on the problem of avoiding the disadvantages of the prior art and of finding a suitable method and an arrangement for the spot-free removal of liquid adhering to surfaces of the material to be treated and of enabling a technically simple implementation.
  • the method according to the invention consists in that compressed air jets are constantly directed from openings in at least one air jet device onto a plane in which the material to be treated is located, a relative movement between the air jet device and the material to be treated being provided and that the air jet device is moved in an oscillating manner in at least one plane .
  • At least one of the oscillating movements is a torsional vibration movement about its own axis. Linear oscillating movements in the direction of the axis about which the rotational oscillating movement of the air jet device takes place are also considered as oscillating movements.
  • the openings in the air jet device can also be designed as movable nozzles, the nozzles executing torsional vibratory movements about axes which are in turn offset by an angle of approximately 90 ° with respect to the axis of the air jet device around which the torsional vibratory movements or in the direction of which the linear vibratory movements occur respectively.
  • the individual vibratory movements can also be carried out simultaneously.
  • the air jet device is elongated, for example in the form of a tube, then the torsional vibratory movements about the longitudinal axis of the air jet device and the linear vibratory movements in the direction of this axis can take place.
  • Movable nozzles in this case preferably execute an oscillatory movement about an axis transverse to the longitudinal axis.
  • the openings can be arranged on at least one surface line of the air jet device. Both holes in the air jet device and nozzles can be provided as openings.
  • the frequencies of the oscillating movements of the air jet device and the pressure of the compressed air jets should be chosen so high that the liquid which adheres to the material to be treated is essentially atomized.
  • the compressed air is directed not only from one direction onto the surface to be dried, but from various constantly changing directions. This ensures that all surface areas, including perforations and undercuts, are grasped and that all liquid drops adhering to them are removed, even when the material to be treated is strongly shaped.
  • the complete removal of the drops and not only their instantaneous displacement is achieved by working with high oscillation speeds. The comparatively sluggish drops cannot evade quickly enough and atomize in the air jet sweeping over them.
  • the compressed air jets are also directed specifically at the material to be treated during the entire treatment time and not only during a half turn when the air jet device rotates. This results in a significantly reduced drying time compared to arrangements with rotating air jet devices.
  • the frequencies and amplitudes of the oscillating movements of the air jet devices and / or the nozzles can be fixed or, depending on the type of material to be treated, set automatically or manually to specific values. This ensures that all surface areas of the material to be treated are detected.
  • the relative movement between the air jet device and the material to be treated serves to sweep the entire surface of the material to be treated with the compressed air jets.
  • the material to be treated can be moved past one or more stationary air jet devices.
  • the air jet devices are moved past the stationary items to be treated. In both cases, the oscillating movements of the air jet devices and possibly the nozzles of the relative movement between the air jet devices and the material to be treated are superimposed.
  • the air jet devices are arranged, for example, on the sides of a bath or dryer in order to be able to blow off all surfaces of the items to be dried at the same time.
  • the material to be treated is hung on product carriers with known fastening means, such as clamps or racks, and transported from transport trolleys from one treatment bath to the next.
  • the length of the goods carriers is in the range up to a few meters.
  • the items to be treated on the goods carrier thus form two large levels, namely a front and a back.
  • the adhering liquid must be removed from both sides.
  • the air jet devices can, for example, be arranged in a horizontal position stationary on at least one side and laterally above the bath level on the treatment container in order to blow off any liquid adhering to the surfaces when the material to be treated is lifted out of the container or when it is lowered into the container.
  • This arrangement is particularly advantageous for recovering valuable materials and for avoiding carryover losses.
  • the relative movement is achieved here when the material to be treated is lifted out of the bath.
  • the lifting speed must be selected so slowly that the adhering liquid is effectively removed from the surfaces when the material to be treated is lifted out of the bath once.
  • a common swivel drive can be provided for their oscillating movements, for example by moving a lifting rod connected to the nozzles for all nozzles up and down, so that the nozzles are set in torsional vibratory movements. If the nozzles have an asymmetrical blow-out opening, this results in pressure jets oscillating on a cone jacket, the axes of which are, for example, transverse to the longitudinal axis of the air jet device.
  • a plurality of stationary air jet devices arranged parallel to one another can also be used. These perform the oscillating movements in at least one direction.
  • the relative movement In this case, the goods for the stationary air jet device are taken over by a hoist that moves it up and down.
  • Transport vehicles are also known in electroplating technology, which are equipped with a cabin for spraying and draining the material while driving.
  • the oscillating air jet devices according to the invention can also be provided in such transport carriages and be arranged such that the items to be treated lifted out of the bath or lowered into the bath are guided past these air jet devices, so that adhering liquid is blown off by compressed air jets as they pass. It is advantageous in this case that an improvement in the quality of drying and a time saving can be achieved at given travel times from one treatment station to the next by effectively removing the liquid from the surfaces.
  • At least one oscillating air jet device is moved past at least one side of the stationary items to be treated.
  • the air jet device can be moved horizontally, vertically or in another direction relative to the product carrier, but preferably parallel to the plane of the material to be treated.
  • a plurality of air jet devices can also be provided only on one side or on each side of the material to be treated. If several air jet devices are used, their movements (torsional vibrations and linear movements) are preferably synchronized with one another.
  • these can also be arranged at an angle to one another, their axial directions being essentially parallel to the plane in which the material to be treated is located.
  • two air jet devices are used on the front and rear, offset by approximately 90 °. These move independently from each other in the horizontal or vertical direction in the dryer arrangement along the material to be treated. This has the advantage that the parts to be dried are blown from further directions. Doubling the air jet devices therefore reduces the drying time for molded goods to less than half.
  • the parts of the material to be treated are moved through a horizontal continuous system for treatment.
  • the air jet devices can be arranged above and below the transport plane of the material to be treated, so that the material to be treated is moved in a horizontal direction between the air jet devices.
  • the air jet devices are preferably stationary and only perform the oscillating movements. However, it is also possible that they perform an additional movement with and against the transport direction of the parts to be dried.
  • the oscillating movements of the air jet devices take place in the same manner and at the same speeds as when the material is treated in diving systems.
  • Complete drying by removing the residual moisture from the surface of the material to be treated is achieved by adding additional heat to the dryer arrangement.
  • the last rinsing bath can be equipped with a heater before drying.
  • the material to be treated absorbs so much heat that the evaporation on the surface is promoted from the inside during the subsequent drying in the circulating air dryer. This is intended to compensate for the evaporation cold that counteracts the drying process.
  • the material to be dried, whether previously heated or not blown by cold air this would prolong the evaporation process.
  • Another serious factor is that compressed air relaxes when it flows out of nozzles and thus cools down.
  • a heater in the compressed air line can be switched on during the final phase of drying.
  • the heated compressed air contributes to the faster evaporation of the residual moisture without having to use the large thermal energy customary in dryers, because the moisture on the material is heated locally and with comparatively small amounts of air. If a treatment item to be dried without stains contains threaded holes or blind holes, small drops of liquid may remain in these holes even when the air jet device according to the invention is used. These are evaporated by a downstream circulating air dryer. The resulting drying spots at these points cannot be objected to for technical or decorative reasons.
  • Clean and dried compressed air is preferably used to generate the compressed air jets. Satisfactory drying results are achieved with just a slight overpressure; for example, with a pressure of 2 bar and three times over the areas to be dried Stain-free drying is achieved in every direction at a speed of 4 meters per minute. The relatively low pressure in the compressed air jet results in low air consumption.
  • the method according to the invention is optimal to the Adaptable treatment items to be dried.
  • FIG. 1 shows a goods carrier 1 on which the items to be treated, here parts 2, are located.
  • the parts are wetted by immersing them in an aqueous bath or spraying them with treatment liquid. After being lifted out of the treatment bath, this liquid adheres to the surface of the parts 2. Individual, non-falling drops form on the surface. These are blown off using the method according to the invention.
  • the elongated air jet devices 3 in the form of tubes 12, which are arranged perpendicular to the plane of the figure and parallel to the material to be treated, are used for this purpose.
  • a plurality of air jet devices can be provided on each side of the item to be treated, either in parallel or at an angle to one another.
  • the air jet devices 3 have openings 6 in the form of bores or nozzles on a surface line or alternately offset on a plurality of surface lines.
  • the spacing of the openings can be arranged either regularly or irregularly in accordance with the geometric dimensions and the surface shape of the material to be treated.
  • the arrows 7 indicate the compressed air flowing into the air jet devices. This flows out of the openings 6 onto the parts to be dried.
  • the air jet devices are each pivoted about their axes by a drive, not shown, as indicated by the double arrows 8.
  • Several air jet devices can be swiveled by a common drive. This ensures perfect synchronization of the swivel movements. In the example of FIG. 1, about nine parts of the air flow are successively caught by the pivoting.
  • the double arrow 9 indicates the swivel range, ie the amplitude of the torsional vibrations.
  • Each part is blown at a different angle, the drops adhering to the surfaces being caught and atomized by the compressed air jets in one direction or the other, depending on the pivoting direction.
  • the air jet devices are set at a relatively high frequency in torsional movements, for example with two to five complete torsional movements per second. However, frequencies that deviate widely from this can also be selected, provided that a sufficiently high frequency is selected to atomize the adhering drops by blowing them off.
  • the air jet devices oscillating in this way are moved slowly and approximately parallel to the parts to be dried by a linear drive.
  • This linear relative movement is represented by arrows 10 in one direction and 11 in the opposite direction.
  • the fast torsional vibration movement and the slow linear movement of the Air jet devices overlap in such a way that each part to be dried is blown at a different angle at any time during a linear movement of the air jet device from one end of the product carrier to the other.
  • the drops are captured by the compressed air jets in rapid succession from different directions and at different angles.
  • An additional linear oscillatory movement of the air jet device perpendicular to the plane of the drawing is identified in FIG. 1 by reference number 13.
  • the amplitudes and the frequencies of the oscillating movements 9 and 13 as well as the path and the speed of the linear movement can be individually adjusted to the material to be dried. However, these parameters can also be set automatically by an external control depending on the material to be treated. Manual adjustments of the amplitudes and frequencies are also possible.
