Definitions
- the invention relates to a device with a rotatably mounted drum through which a fluid flows from the outside inwards, the stable casing of which is provided with a sieve-shaped hole structure or the like over the circumference, and furthermore also a permeable outer covering that covers the casing radially on the outside , between the and the sieve drum jacket is preferably a beam such as screen fabric to increase the distance between the sieve drum jacket and the outer covering.
- a device of this type is known from DE-U-1 886 883 or DE-A-1 806 220. It has the advantage of distributing the air or water flow evenly across the width through the textile material lying on the drum. There is no columnar fluid flow depending on the perforation of the sieve drum shell carrying the textile material, but the fluid is distributed evenly over the surface, the suction from the inside of the drum has an even effect on the surface of the textile material.
- the tubular outer covering from sheet metal or foil as precisely as possible and then to pull it over the drum during assembly. Not only do major problems arise as a result of the friction of the lining on the outer surface of the drum, but - since there must be a certain play, a certain distance between the covering and drum during assembly - the covering will become permanent due to the remaining play warp the drum as a result of the longitudinal pull in the direction of the circumference of the drum, which can lead to folds, warping in the covering.
- the invention has for its object to find a solution to the problem set out.
- a rigid film or a fine sieve plate which is produced in the form of a tube and is provided with the desired perforation all around the circumference, should also be able to be firmly clamped onto the supporting sieve drum jacket.
- an axially displaceable clamping element which extends in the axial direction and is enlarged at least once in the radial direction over the working width of the sieve drum is axially displaceably mounted.
- the rigid outer covering is still manufactured to fit exactly. Now, however, the outdoor air that is absolutely necessary for installation is rendered ineffective by a radially outward tensioning of the outer covering. This will then lay firmly around the sieve drum, lie there under friction, while the clamping line only slightly increases in diameter at the height of the clamping element which extends over the working width.
- the tensioning element is inserted with the same width and height with play.
- the retracted clamping element thus closes with the surface of the screen drum when the outer covering is in place.
- the groove has a recess at least once over its length, in which the radial enlargement of the clamping element lies radially inward. If the tensioning element is now shifted, i.e.
- the radial enlargement of the tensioning element shifts into the area of the air gap between the inner surface of the outer covering and the outer surface of the screening drum and thus clamps the outer covering to rest on the surface of the sieve drum.
- the clamping element can be made of spring steel and the radial enlargement causes a bend in the direction of the dent in the groove of the sieve drum. After the tensioning element has been moved out of the dent, two support areas of the tensioning element for the outer covering will result on both sides of the radial enlargement over the length of the tensioning element.
- this type of bracing can be generated several times over the length of the working width of the drum and / or over the circumference of the drum.
- a device of the type according to the invention is shown as an example in the drawing. Show it:
- FIG. 1 shows a section longitudinally through a conventional sieve drum device for drying, the sheet metal jacket of which consists of a perforated drum jacket with the sheet metal jacket drawn on the outside,
- FIG. 2 shows in cross section a permeable screen drum, which is under suction, for transporting a fleece to be consolidated with water jets, with the nozzle bar assigned to the outside of the screen drum to generate the hard water jets,
- a screening drum device for drying basically consists of an approximately rectangular housing 1, which is divided into a treatment room 3 and a fan room 4 by an intermediate wall 2.
- the screening drum 5 and a fan 6 is rotatably mounted concentrically to this in the fan room 4 behind the nozzle star.
- the fan space can also be arranged in a separate fan housing, not shown here, which is separated from the sieve drum housing 1.
- the fan draws the inside of the drum 5.
- heating units 7 are arranged above and below the fan 6, which consist of pipes through which heating medium flows. The heated air is blown into the storage space above and below the sieve drum, which is bounded by the storage ceiling 10 in the direction of the sieve drum. This ensures an even air distribution over the working width.
- the inside of the sieve drum is covered against the suction draft by an inner cover 8 supported on the axis.
- the jacket structure of the sieve drum carrying the textile material is here characterized by the drum described below with reference to FIGS. B. sheet-shaped outer surface 9 is formed.
- the type of tensioning of the outer covering with the screen drum according to FIGS. 4-6 can be used both when drying material webs with a device according to FIG. 1 and when hydrodynamically needling nonwovens according to FIGS. 2-3.
- the screen drum 5 * shown in FIG. 2 also includes other peripheral parts, which are omitted here for the sake of clarity.
- the fleece 13 to be loaded directly overflows the sieve drum 5 ', to which one or more nozzle bars 14 are directly assigned outside.
- the respective nozzle bar 14 is arranged axially parallel to the sieve drum 5 'and provided on its underside associated with the sieve drum 5' with a nozzle strip (not shown here) for forming the water jets 15.
- the sieve drum 5 "for suctioning the sprayed-on water is placed under suction, for which purpose a suction pipe 8 'is arranged centrally in the interior of the sieve drum 5' and has suction slits 16 which extend to the sieve drum 5 'and in turn the nozzle bars 14 are assigned to them are.
- the screen drum 5 ' consists of a seamless screen drum wall 5, which serves as a support element for the outer covering 9, which is mounted on the outside.
- a fine sieve fabric, a spunlace belt 17, is first stretched onto the sieve drum casing 5, onto which this outer covering 9 is then applied as a sheet or foil.
- the outer covering 9 has to be manufactured as a tube, as a tube with the desired perforation and without a recognizable seam and drawn onto the drum with the jacket plate 5 in the axial direction.
- the outer covering 9 is certainly to be secured against slipping on the end faces of the drum, but torques occur continuously in the circumferential direction on the outer covering during use, which, depending on the sensitivity of the outer covering, can lead to folds or even kinks in the covering. There is no sufficient full-surface friction connection between the sieve drum casing 5 and the covering 9.
- a groove 19 is introduced radially from the outside into the sieve drum jacket 5 over the entire length of the working width, and a clamping element 20 is inserted into the groove 19 in the height and width of the groove 19.
- a dent 21 according to FIGS. 4, 5 is incorporated into the bottom of the groove 19, that is to say into the material thickness of the casing 5 of the screening drum, into which the clamping element 20 is bent in a radially increasing manner.
- the tensioning element 20 can be made of spring steel and, over its length at the level of the dent 21, experience an arc 20 ′ which corresponds to the dent 21.
- the tensioning element 20 fitted into the groove 19 does not interfere.
- the tensioning element 20 is displaced in the direction of arrow 23 according to FIG. 5 relative to the dent 21, specifically into the situation according to this FIG. 5.
- the arch 20 ′ of the tensioning element 20 is jammed in the free space the outer covering 9 with the sieve drum jacket 5 and brings the outer covering 9 around the sieve drum 5 into frictional connection.
- the clamping device according to FIGS. 4-6 can be carried out several times over the working width of the screening drum along a tensioning element 20 and / or several times over the circumference.
- the radial enlargement 20 'of the clamping element 20 can be realized as shown by an arc or else, for. B. by a thickening of the material, such as a weld seam or the like.
- the tensioning element can be provided over its length at the level of the perforation of the sieve drum casing 5 with a suitable perforation 25 according to FIG. 6, in order to ensure the uniform flow also in this area of the drum ,
- a spunlace is also placed on the outside of the screen drum jacket 5 to increase the distance between the outer covering 9 and the screen drum jacket 5.
- band 24 which can be doubled, but can also be omitted depending on the application.
