Definitions

  • the invention relates to a device for treating hides with liquids in the so-called wet processes, for example liming, pickling, tanning, dyeing or the like, consisting of a liquid-permeable base which absorbs the skin relentlessly and a treatment device which can be placed essentially tightly on the top of the skin , by means of which the treatment liquid is penetrated into the skin under high pressure.
  • those wet treatment processes are those treatment stages in which the skin is treated with dissolved chemicals with a high fluid requirement.
  • Dyeing processes could already be improved somewhat (DE-PS 822 060) in that the skins lie on a belt and are guided past a paint spraying device, which at least reduced the difficulties in manipulating the skin.
  • the need for coloring liquid is considerable, since it is sprayed onto the skin at a distance, a large amount of coloring liquid does not come into contact with the skin and, furthermore, a considerable exposure time must be provided in order to penetrate the coloring liquid into the skin to enable. Coloring through is not possible in this way or only with great expenditure of time.
  • the treatment liquid In the other aforementioned wet processes, the treatment liquid must penetrate the skin intensively and completely, which is why it must be in constant contact with the treatment liquid over a long period of time. In order to enable targeted working with the lowest possible fluid requirement even in these wet processes, it has been proposed (EP-OS 0 009 081) to introduce the treatment fluid into the skin under high pressure in a kind of inoculation process.
  • the invention has for its object to improve the aforementioned and aforementioned device in such a way that a uniform penetration of the treatment fluids into the skin is ensured at reduced working pressure.
  • the treatment device has a plurality of liquid supply channels arranged approximately perpendicular to the base, which expand over a large area on the underside of the device facing the skin and are arranged to fill the area, and that between the underside of the device and the Skin arranged a net-like pad and the space between the pad, skin, pad and treatment device is essentially sealed off from the outside.
  • the feed channels have a comparatively large-area expansion of, for example, several cm 2 in the region of their mouth, these extensions having such a geometric outline and such an arrangement that they connect closely to one another, that is to say they cover a large area overall.
  • the mesh-like support is provided on the skin, which on the one hand levels the skin somewhat in this area, and on the other hand for a punctual penetration of the treatment liquid over a larger one Cross section ensures.
  • the space between the base, the skin, the support and the treatment device can be sealed off from the outside. This is usually possible in that the parts are moved together in a correspondingly tight manner without the need for separate edge seals.
  • the large-area extensions of the feed channels on the underside of the treatment device can have a polygonal or round outline, at the center of which at least one feed channel opens.
  • the extensions can, for example, have an outline in the form of equilateral triangles, squares, polygons or circles.
  • a likewise mesh-like intermediate layer can also be arranged between the skin and the base in the device according to the invention, in order to allow the treatment liquids which penetrate the skin to run off. Since such an intermediate layer would, however, be too flexible to absorb the treatment pressure present on the other side, an unyielding underlay must also be provided, which then has a plurality of processes arranged next to one another for the treatment liquid penetrating the skin. The excess treatment liquid penetrating the skin thus penetrates through the fine-meshed intermediate layer to the unyielding base, where it is carried away by the processes.
  • the mesh-like support and intermediate layer consists of a fine-mesh plastic or metal mesh, which on the one hand has the necessary flexibility to adapt to unevenness in the skin, and on the other hand has the necessary resistance to the working pressure without the mesh size changing under the influence of the working pressure .
  • metal mesh fulfills another task, namely to form a support for the skin, which distributes the treatment liquid supplied from the outside uniformly and allows it to penetrate into the skin at points.
  • the underside of the treatment device or the extensions arranged there to fill the area can have an extent corresponding to the width or length of the skin, at least in one direction of extension.
  • the treatment liquids are introduced into the skin in strips, which in turn is then moved batchwise through the device.
  • the skin between the support and the intermediate layer are designed as conveyor belts.
  • the skin can therefore be placed between the two conveyor belts and transported between them into the device, so that the manual tasks required for the entire treatment are limited to the task of the skin at the inlet of the conveyor belts and the removal of the skin at the outlet of the conveyor belts. If necessary, the skin can also be thrown off at the conveyor belt outlet.
  • the base is designed as a table and can be raised against the treatment device.
  • the skin is introduced between the support and the treatment device by means of the metal nets designed as conveyor belts, then the table is raised against the treatment device with simultaneous pressing of the intermediate layer, skin and support against the treatment device and with a tight seal to the outside, whereupon the treatment liquid is passed over the feed channels can be fed.
  • the base is designed as a circumferential link belt, between the links of which the treatment liquid can run off.
  • the link belt forms a sufficiently rigid support for the skin, which is also transported here between a fine-meshed intermediate layer and a support.
  • the link belt can be trough-shaped in the area of the treatment device and the underside of the treatment device can be curved to fill the trough.
  • the skin between the support and the intermediate layer is conveyed into the trough between the treatment device and the link belt and can in turn be treated batchwise, but advantageously also in a continuous flow.
  • the treatment device is designed as a rotating cylinder, on the circumference of which the extensions of the feed channels are arranged, the feed channels being controllable into their open position only in the region of the trough.
  • the extensions on the underside of the treatment device always remain in the same position relative to the skin, so that the exposure time of the treatment liquid can only be controlled by the transport speed through the trough gap. In this way, skin to skin can be moved through the treatment device.
  • the fine-meshed support and intermediate layer outside the treatment device is at least one cleaning device, e.g. a spray device is assigned, by means of which impurities, which stuck between the meshes and originate from the skin, can be removed.
  • the spray device can be operated with pressurized water or compressed air. In this way it is ensured that, above all, the fine-meshed support has free mesh cross-sections before each entry into the device, in order to enable the treatment fluids to be distributed correctly.
  • the device according to the invention is further characterized by a collecting container which holds the excess treatment liquid penetrating the skin and from which the liquid can be recirculated.
  • the device according to the invention makes it possible to work with highly concentrated treatment liquids and these treatment liquids do not or only minimally change their composition during the treatment, the excess of the treatment liquid can be reused.
  • a purely mechanical preparation e.g. filtering out the treatment liquid so that it can be fed back to the treatment device. Only the losses caused by penetration into the skin can be compensated for in terms of quantity. Waste water does not occur in large quantities, at least, since only treatment liquid that can no longer be used for chemical and / or physical reasons must be removed. These are extremely small quantities with well-known ingredients that are easy to control in waste disposal.
