Definitions

  • the invention relates to a device according to the preamble of patent claim 1.
  • the treatment bowl is denoted by 1 and the intermediate floor by 2.
  • the intermediate floor 2 stands with vertical end plates 4 or similar elements in the treatment bowl 1 and is supported in the middle part by spacers 5 on the bowl bottom 10.
  • the spacers 5 are preferably firmly connected on the one hand to the intermediate floor 2 or form an integral part of the intermediate floor.
  • At least one of the spacers is preferably anchored to the shell base 10 by means of a snap or screw connection 6.
  • the intermediate base 2 is securely fixed against undesired lifting from the shell base even in the case of strong flow.
  • the leaves to be treated are transported by means of transport and nip roller pairs 71-72 and 73-74.
  • the respective upper roller 71 or 73 can be driven directly by a motor and the lower one is connected to the drive in a free-running manner or via an elastic member.
  • a gap 31 or 32 is left free between the shell side walls 11 and 12 running transversely to the transport direction T and the edges 21 and 22 of the intermediate floor 2.
  • the side wall 12 on the outlet side in the transport direction T is designed in the manner of a hollow profile as a liquid distributor 121 and underneath the intermediate floor 2 with a horizontal row of e.g. Provide 20 to 25 feed nozzles 120 with a width of 250 mm for the treatment liquid.
  • the side wall 11 on the sheet inlet side is designed as an overflow for the liquid into a collecting channel 8. Also connected to the sheet outlet side shell side wall 12 is a collecting channel 9, which receives the liquid squeezed out of the continuous leaves by the pair of rollers 73/74 and liquid that reaches the side wall 12.
  • the overall device comprises several, in particular three or four such stations connected in series.
  • Example For the silver color bleaching process first a development station and then one or two bleaching stations and finally a fixing station. All stations are constructed identically. From the second treatment station (B), therefore, only the “beginning” of the treatment tray 1B with the front tray side wall 11B and the associated collecting channel 8B is shown.
  • all stations are built on a common base plate 1000, which continuously forms all floors 10, 10B etc. of the treatment trays 1, 1B etc. and all floors 80, 90, 80B etc. of the collecting channels 8, 9 and 8B etc.
  • roller pairs 71/72, 73/74 etc. each (73/74) except the first (71/72) and last (not shown) is assigned to two stations together.
  • a storage and buffer vessel 7 is arranged on the base plate 1000 below the shell 1 and the collecting channels 8 and 9, which is open at the top and is firmly connected to the base plate by its upper edges, in particular by gluing or welding.
  • the volume ratio between the storage and buffer vessel 7 and the treatment bowl 1 is approximately 1.5 to 2.5, preferably approximately 1.8.
  • the collecting channels 8 and 9 have floor drains 81 and 91 through which the liquid can flow into the vessel 7.
  • 70 is a vent hole for the vessel 7 and 100 are drain holes for the treatment bowl 1.
  • the storage and buffer vessel 7 has side walls that converge in the shape of a funnel.
  • a line 60 leads from the lowest point of the vessel 7 to the suction side of a circulation pump 601, the pressure side of which is connected to the liquid distributor 121 via a thermostatically controllable heater 602 and a line 63.
  • a lockable floor outlet 700 is provided at the lowest point.
  • the stations following in the transport direction T each have the same arrangement, each with a buffer and storage vessel and a circulation pump, etc. Of these, only one wall of the vessel and its vent hole and one of the emptying holes of the treatment bowl are visible in FIG. 1 and are designated with 7B, 70B and -100 B, respectively.
  • the buffer and storage vessels 7, 7B etc. of all stations are formed by a single, connected component which is glued or welded to the base plate 1000 with its upper edge surfaces.
  • the liquid is pressed into the treatment bowl 1 by means of the circulation pump 601 via the thermostatted heater 602 via the distributor 121 through the feed nozzles 120.
  • the liquid overflowing through the shell side walls 11 and 12 reaches the storage and buffer vessel 7 via the collecting channels 8, 9 and from there back to the pump 601.
  • the drainage openings 100 are dimensioned so narrow that only a small fraction is caused by them during operation of the amount fed through the nozzles 120.
  • the circulation system in particular its pump 601 and the cross sections of the feed nozzles 120 are dimensioned such that the liquid flows into the treatment bowl at a flow rate of at least 0.5 m / sec., Preferably about 1 to 3 m / sec.
  • the feed nozzles 120 preferably have a diameter of approximately 1-2 mm, in particular 1.5 mm, and are arranged at a mutual spacing of 10-30 mm, in particular approximately 20 mm, in the lower quarter of the container wall.
  • the pump output and thus the inflow speed can preferably be regulated.
  • the side wall 11 of the treatment dish 1 on the sheet inlet side is shaped in such a way that liquid flowing to its lower part is deflected upwards and in the opposite direction.
  • the wall 11 as a whole could be shaped accordingly, that is to say it could be curved outwards.
  • a flat wall is provided and this is equipped with a horizontal deflection strip 110 above the level of the intermediate floor 2.
  • This bar can be glued or welded to the container wall or integrally formed with it.
  • the ledge 110 projects so far into the shell that its longitudinal edge lies at a vertical distance just before or even behind the intermediate floor edge.
  • the upper surface of the intermediate floor 2 is formed by an asymmetrically gabled roof-like profile running transversely to the sheet passage direction.
  • the surfaces FF of this profile on the blade run side are relatively flat and lie at an angle a of at most 60 °, preferably 5-30 °, to the horizontal.
  • the height h of the profiling is approximately 1-10 mm, preferably 2-5 mm.
  • This arrangement forms, together with the shell cover 3, the passage gap D. Due to the effect of the profile described, a homogeneous flow through the flow gap D is achieved and, at the same time, a perfect sheet passage is ensured.
  • the gap width D is approximately 3-10 mm, preferably approximately 7 mm and can also be adjustable or optionally adjustable.
  • a horizontal surface area FH with a preferably polished surface is interposed between the gently rising run-up profile surface part FF and the steeply falling run-off surface part FS.
  • the length of this surface part is approximately 1/4 to 1/2, preferably approximately 1/3 of the length of the flat rising part FF.
  • the sheet outlet side shell side wall 12 extend. This leadership, which extend beyond the edge 21 of the mezzanine floor 2 up to close to the sheet outlet side shell side wall 12.
  • these guide elements FU are very narrow, so that they do not hinder the flow (SO / SU). They have approximately the same slope as the profile surface parts FF on the run-in side and improve the sheet guidance in the run-out area.
  • the entrance and the exit of the passage gap D are by the corresponding upper edges of the side walls 11 and 12 and the opposite overlying guide surfaces of the cover 3 are formed.
  • the sheet edge 111 on the sheet inlet side is chamfered at an angle of 20 to 40 °, preferably approximately 30 °, rising inwards.
  • the cover 3 has a guide surface 311 which is inclined downwards in the transport direction, which lies exactly opposite the oblique shell edge surface 111 and forms an angle of approximately 30 to 60 ° therewith and has a visible transition 312 (flat edge ) having.
  • a wetting line that is as straight as possible and perpendicular to the transport direction T is achieved.
  • the sheet-edge-side shell edge 122 is bevelled with an angle of approximately 20 to 60 °, preferably approximately 45 °, with rounded edges, increasing in the direction of the sheet outlet (r).
  • the cover 3 has in the sheet outlet area a guide surface 322 which rises gently to the outside and ends in a recessed step 323. This step 323 lies between the outlet-side end of the intermediate floor 2 and the contact surface 122 of the shell wall 12. This arrangement terminates the contact between the bath and the sheet in a precisely defined straight line running perpendicular to the direction of transport and entrains liquid and air bubbles at least greatly reduced.
  • the asymmetrical gable roof-like design of the lower guide surface of the passage gap could also be referred to as "sawtooth".
  • the transitions (edges) between the different profile surface parts can be rounded off and the surface parts themselves do not necessarily have to be flat.
  • the profiling could be a kind of corrugation with flat tarnishes and steep waste.
