Definitions

  • the invention relates to a device for flowing, continuous Heat treatment of web-shaped textile goods, nonwovens or paper with one gaseous treatment agent circulated in the device, with a below Suction-type, permeable drum with bottoms on the front as Transport element, which on its circumference with a sieve-shaped or perforated Covering is covered, being firmly connected to the floors between the bottoms of the drum Sheet metal strips extend from floor to floor, the width of which extends extends in the radial direction.
  • a device of this type is known from DE 38 21 330 A1. It has the advantage that it is optimally permeable to air without reducing the stability of the drum is. Another advantage is the screw construction realized on this device. Without having to resort to the previously known welded construction, In this way, all drum casing elements are screwed on the bridge connections through the connecting webs running in the circumferential direction the sheet metal strip extending longitudinally over the drum all over the drum firmly connected. The disadvantageous structural changes in the metal in the Manufacturing of otherwise necessary weld seams are with this screw construction avoided.
  • the connection of the metal strips with the bottoms of the Drum once with a bottom and once with the nozzle star through which the Fan sets the interior of the drum under suction when in use exposed to greater thermal loads in practice.
  • the floors have a larger one Heat capacity than the metal strips. If when a cold good comes in the heated drum housing shocked the metal strips when they came into contact with the goods cool down, this initially does not apply to the floors, so that there are greater tensions in the material that cause cracks or dents on the drum. This is regardless of the drum construction, i.e. whether it is welded or screwed.
  • the invention is based on the tasks, a connection between the metal strips or their associated fastener and the adjacent one Bottom of the drum to create the constant balance of the due to the changes in material dimensions due to temperature changes in allows this area so that there is no increased material stress on the Drum bottoms, especially in the area of the connection points to the metal strips is coming.
  • the invention provides for solving the problem, for Fastening the metal strips with the bottoms each a separate, both with the Sheet metal strips as well as firmly connected to the assigned floor and yet provide articulated connecting element.
  • connecting element itself and / or the connection with the floors or the sheet metal strips using permanently tightened screws to enable. It is essential, however, that the connecting element also operate is movable and elastic in relation to the respective movements of the drum shell can allow onto the drum bottoms, permanently and without material fatigue all parts involved.
  • a screen drum device basically consists of an approximately rectangular housing 1, through an intermediate wall 2 into a treatment room 3 and Fan room 4 is divided.
  • the screening drum 5 is concentric to this a fan 6 rotatably mounted in the fan chamber 4.
  • the fan space can also be separated from the screen drum housing 1, separate fan housing, not shown here.
  • the fan draws the inside of the drum 5. That too is Drum construction on a wet treatment device that is also only for suction of liquid can be the subject of the patent. The overall construction is then adjust accordingly.
  • heating units 7 above and below the fan 6 which consist of pipes through which heating medium flows.
  • the sieve drum is in the area not covered by the textile material 10 on the inside of a not shown Inner cover covered against the induced draft.
  • the carrying the textile 10 Sheath structure of the screen drum is due to the sheet metal strip structure described below educated. This is surrounded on the outside by a fine-mesh sieve 9, that with the front of the drum on the bottom 12 and on the bottom 11 the nozzle star 11 'is kept tense.
  • the sheet metal strip structure consists of axially aligned sheet metal strips 13, the radial of which aligned height emerges from Figures 2-4. So that's it sieve-shaped covering 9 only on the radially outer edges of the metal strips 13 on.
  • the metal strips 13 are next to each other at a defined distance both floors 11, 12 by the connecting element 17 shown in FIGS. 3 and 4 attached. So that this distance is fixed over the circumference of the drum, are used as spacers serving connecting webs, generally designated 14, which by means of screws 15 and 16 extending over the circumference with the Sheet metal strips 13 are connected.
  • the metal strips 13 must be connected to the floors 11, 12, because they carry by the suction against the drum shell formed by the parts 13, 14 pressed textile goods 10. On the other hand arise during operation Temperature changes especially in the area of the connection of the drum jacket with the drum bottoms material tensions that destroy a rigid connection being able to lead. So it is advantageous to go there for a mobile connection to care.
  • This is shown in principle in Fig. 2.
  • the sheet metal strip 13 is said to Bottom 11, 12 be movably attached. This is done via a connecting element 17, that is articulated on the one hand on the bottom 11, 12 and on the other hand on the sheet metal strip 13 is attached. Since additionally between the end face of the metal strip 13 and the associated wall of the floor 11, 12, an air gap 13 'is left free, can now a shift of the sheet metal strip 13 upwards or - as dashed shown - can also be carried out downwards during operation.
  • the connecting element 17 consists of two connecting arms 18, 19 which are connected to one another by a Screw 20 are movably connected and the free ends of the one hand with the Sheet metal strip 13 movable by a screw 21 and with the respective floor 11, 12 by means of a mandrel 22 extending through the base 11, 12 over a fixed tightened mother are firmly connected here.
  • the connecting arm 19 in the area of the base 11, 12 consists of a block 24, which has a central bore through which the screw 20 can be pushed.
  • This block 24 has an axially parallel contact surface that on the adjacent inner surface of the floor 11, 12 is present. From the contact surface extends from the block 24 through a Bore in the bottom 11, 12 of the mandrel 22, at the end of which a thread is provided is to which the nut 23 can be turned. This connection is rigid.
  • the bolt of the screw 20 or the screw 21 has on its opposite the nut End of a flat piece 25, which is the head of the screw. This head is supposed to Do not apply in height and only make the tight screw connection. To the Tightening the nut during assembly is a cut in the flat piece 25 25 'intended for the use of a wrench.
  • the block 24 or the connecting arm 19 is the other connecting arm 18 rotatably attached. It consists of a parallel to the sheet metal strip 13 Lever, at the ends of which a hole for the screws 20, 21 is made.
  • the Bolt of the screw 20 is initially surrounded by a spacer cylinder 26, which is both about the height of the connecting arm 18 and the height of the immediate overlying trestle 24 extends and is fitted into these holes.
  • the distance cylinder 26 is a small amount (about 0.1 mm) longer than the height of the Block 24 with the height of the connecting arm 18 so that after tightening the Screw 20 of the connecting arm 18 is pivotable about the block 24.
  • the movable connection is now created between the centering ring 29 and the associated one Bottom 11, 12.
  • the hinge ring 32 consists of a large number of connecting elements, 6 and 7 resulting connecting arms 18, which are not radial are aligned, but along a secant, i.e. opposite the radial in an angle less than 180 °.
  • the connecting arms 18 are each of two diameters articulated, the radially inner is in the embodiment on the floor 11, 12 and the radially outer one on the centering ring 29 a change in diameter of the drum a movable compensation to the drum base 11, 12 adjust, e.g. B. straighten the diameter of the drum the connecting arms 18 on, so that the angle of the connecting arms 18 to Radials enlarged.
  • the connecting arms 18 each have a bore at their ends, through which a screw 22, 23 or 21 is pushed and either with the Centering ring 29 or the associated base 11, 12 is screwed.
  • a spacer ring 28 slid onto the screw bolts 21, 22, which in turn increased in height by one measure is thicker than the flat piece 25 of the head of the screw 21, 23 in order to rub the Avoid head 25 on the bottom 11, 12 or the centering ring.
