Description

Passing devices for dyeing fibrous materials in the form of a canvas, including sequentially installed dyeing and washing baths, in which fibrous material passes sandwiched between two mesh conveyors, squeezing devices and liquid circulation devices are known.

The peculiarity of the described passage apparatus is that, in order to improve the quality of material processing, the dyeing and washing baths are made in the form of boxes provided inside with a hollow cylinder, the surface of which is formed by roller rollers, which are guides for mesh conveyors with fibrous material , and in the hollow cylinder of the washing bath, radial partitions are installed for separate removal of polluted water from the bath. For continuous transfer of fibrous material from the dyeing bath to the wash bath, the mesh conveyor is common to both baths.

The drawing shows a diagram of a throughput apparatus for cutting fibrous materials.

The flow apparatus consists of two baths installed in series: dye bath 1 and wash bath 2. Dye bath /. It is a cast-iron box, provided inside with a hollow cylinder 5, the surface of which consists of rollers 4, which form roller conveyors. The rollers 4, mounted in the full width of the box, rotate freely in the support plates (not shown in the drawing) attached to its side walls.

Mesh conveyors move along the rollers 4 with an endless belt — the lower conveyor 5 envelopes a series of guide rollers, including the drive roller 6, and the upper conveyor 7, also envelopes a series of guide rollers, including tension rollers 8. For continuous transmission fibrous material 9 from the dye bath /

No. 118485

the wash bath 2, the lower screen conveyor 5, is common to both baths. The conveyor edge slides along the guides 10, cast together with the side covers of the boxes, under the influence of the upper pressure rollers 11. In the upper part, the guides 10 are covered with a blind cover 12.1,

The work of the passage apparatus is as follows.

The fibrous material 9 in the form of a canvas, sandwiched between the belts of the lower mesh conveyor 5 and the upper conveyor 7, enters the dyebath 1 and moves with them along the rollers 4 of the roller table. In the bath 1, a solution is poured, which after introducing the fibrous material 9 into it, is divided into two zones: the inner zone 13 and the outer zone 14. The interface is a layer of fibrous material 9, side guides 10 and a cover 12. The solution is pumped ( the drawing is not shown) is sucked from the inner zone 13 through the pipe 15 and fed to the outer zone 14. Thus, the solution is continuously circulated from zone 14 to zone 13 through a layer of fibrous material 9, painting the latter.

From the dyebath 1, the fibrous material 9 enters the washbath 2, in a hollow cylinder 16, which has radially three baffles 17, which divide the internal cavity of the cylinder 16 into three zones. Water is aspirated from each zone by an independent pump through pipes 18, with the most contaminated wash water from the first zone along the bed of fibrous material 9 being removed from wash bath 2 to the outside, and water from the other two zones returning to wash pool 2 and again passes through the fibrous material 9, washing the latter.

After the dye bath / and the wash bath 2, the fibrous material passes between the squeezing devices 19.

Subject invention

Claims (2)

1. A dyeing apparatus for dyeing fibrous materials in the form of a canvas, including successively installed dyeing and washing baths, in which the fibrous material passes sandwiched between two mesh conveyors, squeezing devices and a device for circulating a liquid, characterized in that the quality of the material processing, the dyeing and washing baths are made in the form of boxes supplied inside with a hollow cylinder, the surface of which is formed by rollers of the roller table, which are guides for etchatyh conveyors with a fibrous material, wherein the washing bath in a hollow cylinder mounted radial partitions for separate removal from the bath contaminated waters. 2. The passage apparatus according to claim 1, characterized in that, in order to continuously transfer the fibrous material from the dyeing bath to the wash bath, the lower mesh conveyor is common to both baths.
