Commodity tree with perforated jacket for the treatment of thread-like or web-shaped material with liquids, steam or gases

The invention relates to a tree with perforated Coat for the treatment of thread-like or web-like material with Liquids, steam or gases, the interior of which is traversed by the treatment medium.

The treatment medium is conveyed through a hollow peg of the tree into the interior and passes through the openings in the tree shell and ends up in the roll of goods carried by the tree. The treatment medium then flows into the container surrounding the tree, is drawn off from there by a pump and fed back into the interior of the tree.

It is also known for closed and open treatment devices, perform the forced circulation in the reverse direction. In this case, the treatment medium flows through from the container the roll of goods into the interior of the tree and is drawn off by a pump through a hollow pin and back into the container promoted.

To ensure proper handling, e.g. coloring of the rolled up To achieve l'extilware, the diameter of the The tree and the roll of goods must be coordinated with one another. The diameter of the tree must not be too small. From this it follows the use of a large amount of treatment medium which, among other things, has to fill the entire interior of the tree.

Except for the special costs caused by the large fleet volume disfigure, burdened the weight of the fleet located in the interior of the tree or the like. after the liquor has been withdrawn the container the roll of goods. In addition, the large amount of air located in the interior of the tree when the Compressed liquor in the interior and must be pressed through the roll of goods.

The invention is based on the object of the flow space in the fe to reduce the interior of the tree so that the system with a smaller amount of treatment medium than before can be operated.

This object is achieved according to the invention in that a flow space in the cylindrical interior of the tree is arranged for the treatment medium reducing displacement body.

This measure also ensures that, when chemicals or dye liquors are added, those that maintain the liquor cycle Pump a dilution of these additives is significantly reduced.

"In an advantageous embodiment of the invention, the "Displacement body attached coaxially to the tree and connected to the shell of the tree via spacers.

It is advantageous to streamline the displacement body shape so that the treatment medium from the interior of the tree into the roll of goods over the entire working width of the tree is fed at the same speed as possible. This promotes an even treatment of the roll of goods.

It is also conceivable to arrange the displacement body in a floating manner in the interior of the tree so that the displacement body floats upwards in the container surrounding the tree as the level of the liquor rises.

The reduction in the flow space within the goods tree also brings about a considerable reduction in the amount of air that must be pressed by the roll of goods when the treatment medium flows into the tree.

To keep this greatly reduced amount of air away from the roll of goods, In a further embodiment of the invention, an angled, angled, mounted in the longitudinal axis in the interior of the tree Eohr extending to the vicinity of the mantle is provided, which is in the upward position for drawing off the air and in the downward position can be used to draw off the liquor when emptying the treatment tank.

Further characteristics and features of the invention emerge from the following description of two exemplary embodiments, which are shown in FIG are shown in the drawing. Show it:

1 shows a tree treatment apparatus in longitudinal section, FIG. 2 shows a section along the line II - II in FIG. 1,

5 shows a second exemplary embodiment of a tree treatment apparatus in longitudinal section,

Fig. 4- a section along the line IV - IV in Fig. 3

In the construction according to FIG. 1, the tree 1 with its hollow pins 2, 3 is rotatably supported in a stationary container 4. It is also common not to rotate the tree in the retention tank or autoclave. The tree 1 has a perforated outer jacket 5, which carries the roll 6 of goods. The perforations in the edge areas of the roll are depending on the given working width by cuffs 6a or the like. covered.

In the interior of the tree 1 there is a displacement body 7 in the form of a Hollow cylinder is provided, which is stiffened by disks 8, 9 and 10. In the plane of these disks are spacers'11,

109822/1 6? 9

which fix the displacement body 7 relative to the outer jacket 5 of the tree. The flow space in the interior of the tree 1 is determined by the end disks 12, 13 of the displacement body and by its cylindrical jacket.

The treatment liquor is introduced into the interior of the tree 1 via the hollow pin 2 and flows over the chamber 14 and the input space 15 in the roll of goods 6. "From there, the Treatment flofcte in the container 4-, is via a pipe 16 withdrawn from the container and fed back to the interior of the tree 1 by means of a pump via the hollow pin 2-.

In the chamber 17, which is opposite the chamber 14 of the tree, an angled pipe 18 is pivotably mounted, which is in the position shown in full lines for venting the flow space of the goods tree. In the dashed position, the angle tube 18 is used to draw off the liquor from the flow space of the tree.

In a modification of this construction, it is also possible to do what has been described to arrange angled pipe in the chamber 14 or to provide separate pipes for extracting the air and the liquor.

In the embodiment according to FIG. 3, the displacement body is 19 'designed in a flow-favorable manner, so that the treatment medium entering the interior of the tree 1 via the hollow pin almost at the same speed over the entire Tree width can enter the roll 6 of goods through the perforated outer jacket of the tree 1.
