Definitions

  • the invention relates to a sieve drum washing machine with a sieve drum rotatably arranged in a housing about a horizontal axis, and guide devices through which a web of material is introduced in the upper housing region and is removed after the sieve drum has been rotated.
  • Sieve drum washing machines are used for washing web materials, for example, for low-tension washing of woven and knitted goods, in which the material is washed in a continuous process.
  • the washing liquor is sucked out of the container through the web of material which conforms to the sieve drum and the sieve drum by means of a pump into the interior of the sieve drum.
  • the fleet is filtered and pumped back into the trough.
  • the liquor is also continuously circulated, filtered and sprayed onto the material web with spray nozzles.
  • the circulation pump, the filter device, the spray nozzles and the associated line system require a relatively high level of design effort and represent a source of interference.
  • the energy requirement is relatively high.
  • the liquor volume in the trough is large, so that a large heating capacity is necessary.
  • the fleet exchange is low and there is a strong enrichment of the fleet.
  • the invention has for its object to provide a screen drum washing machine of the generic type, the manufacturing and operating costs are reduced compared to the conventional solutions.
  • This object is achieved in a sieve drum washing machine of the above type in that at least one rotatable vane roller, parallel to the sieve drum, is provided on the side of the sieve drum at the level of the liquor level in order to spin the liquor onto the web.
  • a wing roller of the type used here is a relatively simple component. It consists of a cylindrical core, which is arranged parallel to the screen drum, and a number of axially parallel blades on it Core, so roughly has the shape of a radial impeller.
  • the wing roller can be rotated using a simple drive mechanism with low energy consumption.
  • the sieve drum preferably comprises a cylinder closed on the lateral surface and on the end faces, on the circumferential surface of which axially parallel channels which are open at the ends are formed with the aid of axially parallel webs fastened to the cylinder and a cylindrical sieve enveloping them.
  • the liquor which is thrown onto the material web by the wing roller passes through it and through the sieve into the channels from which it flows back into the trough at the front ends.
  • the liquor does not penetrate the inside of the screen drum cylinder, so that it acts as a displacer in the liquor. This allows the amount of liquor to be reduced considerably, while on the other hand the liquor advantageously flows through the material and is thus effectively cleaned.
  • the fleet level is preferably kept essentially constant by an overflow.
  • several machines are set up in series and the fleet flows through them in succession.
  • the following machines are preferably gradually lowered, so that the fleet can flow through all the machines continuously via an inlet and an overflow without the need to use a pump.
  • Such a system is preferably traversed by a material web in countercurrent, so that the material is first prewashed with the most contaminated liquor and completely washed out step by step by the fleet, which becomes cleaner step by step.
  • spreader rollers can be provided to hold the material wide and pendulum rollers can be used to maintain a continuous web tension.
  • the space occupied by the fleet in the container also referred to in the present context as a trough, is kept relatively small according to the invention.
  • the bottom of the trough follows the underside of the sieve drum at a short distance in an arc, and only extensions to accommodate the wing rollers are provided on the sides, which expediently plunge into the liquor approximately up to the central axis.
  • the wing rollers preferably rotate on the upper side towards the screening drum and are shielded by baffles on the side facing away from the screening drum.
  • the washing machine has a housing 10, the lower region of which is designed as a trough 12.
  • a sieve drum 14 is arranged in the housing and can be rotated about a horizontal axis 16. This axis 16 lies approximately at the level of a wash liquor, designated 18, which is located within the trough 12.
  • the screening drum 14 consists of a cylinder 20, which is completely closed on the peripheral surface and on the end faces, not shown, and on the peripheral surface 16 webs 22 are fastened parallel to the axis of rotation 16, which have the form of radial lamellae.
  • the webs 22 are encased by a sieve 24, which can consist of sieve wire or perforated plate. In this way, axially parallel channels 26 are formed between the cylinder 20, the webs 22 and the screen 24, which are open at the axial ends. These channels will be discussed in more detail later.
  • the vane rollers 28, 30 consist of a rotatable cylinder 32 and a number of radial, lamellar vanes 34 on its circumference, that is to say they have approximately the shape of a radial impeller.
  • the two wing rollers are rotated with the upper side to the screen drum 14, so that the liquor is thrown onto the screen drum in accordance with the arrows not shown in the drawing.
  • the wing rollers 28, 30 are shielded by baffles 36, 38.
  • a web of material 40 enters through an inlet 42 in the upper region of the housing 10 and through an outlet 44 in the upper region of the housing, but on the opposite side.
  • the material web runs inside the housing over oscillating rollers 46, 48 or other devices for keeping the web tension constant and between these oscillating rollers 46, 48 over about three quarters of the circumference of the sieve drum around it at the bottom.
  • the wash liquor is flung onto the web 40 with the aid of the wing rollers 28, 30.
  • the washing liquor penetrates the web and the sieve 24 and flows through the channels 26 to the two axial ends of the sieve drum and exits here.
  • the web is therefore flowed through in the interest of good cleaning.
  • the washing liquor does not enter the inside of the screening drum as in conventional solutions, so that its cylinder 20 acts as a displacer and only a very small amount of liquor is required.
  • the trough 12 in turn follows the contour of the underside of the screen drum 14 and the side wing rollers 28 and 30 at a relatively small distance. This also means that only a relatively small amount of liquor is required.
  • a chamber 50 is provided which extends downwards and which also has the function of a liquor sump and receives a heating coil 52 for direct heating or a steam inflow pipe for direct heating of the liquor. Otherwise, 12 heating wires 54 or the like are provided as indirect heating on the underside of the trough.
  • two spreader rollers 64, 66 are shown, which are rotated in the opposite direction to the conveying movement of the material web and have a profile, known per se, on the circumference for holding the material wide. Downstream squeezing units and other devices for conveying the web are not shown.
