SU9351A1 - Apparatus for drying, aging (oxidizing) or carbonizing fibrous woven material - Google Patents

Description

The proposed device for drying, aging (oxidation) or bonding maps of fibrous materials refers to known devices, which consist of a chamber where the material to be dried in the ribbon passes on air-permeable supports or rollers and where warm air is blown.

The proposed device consists in the fact that parallel to the flat plate of the material to be dried from above or below it, or both from above and below, have groups, or rows of blowers or fans mounted on a common drive shaft; these fans produce circular air streams directed either all in one direction along the line of their shafts, or in pairs in opposite directions to each other.

In the schematic drawing of FIG. 1 depicts a longitudinal section of the proposed device; Fig, 2 is a cross section; FIG. 3 is a longitudinal section of the device in another form; FIG. 4 - cross section; FIG. 5 is a longitudinal section in the third form c); FIG. b - cross section. In the drawing, numeral 1 denotes a tape of the material being dried, rolls a Q roller 2, and drags on a roller 3 after drying. Figure 4 denotes an endless conveyor belt that passes through the air on the rollers 5. Figure b indicates a tunnel-shaped drying room in which the blowers or fans 7 are arranged in rows on a common drive shaft and, moreover, in the direction of their common shafts parallel to the belt of the material being dried, they produce circular air streams 8 directed all in one direction or in pairs in opposite directions, which flows relate primarily to the outer surface of the strip of material being dried. Such an action of the fans 7 in the device shown in FIG. 1-4, is due to the fact that the fans are arranged in rows and that the wings of each adjacent pair of fans

They are planted in opposite directions, as well as the fact that the fans are surrounded on one side by a dense, air-tight wall, and on the other side by an air-permeable conveyor belt. In the drying device shown in phi 5 and 6, two air permeable endless conveyor belts 4 are placed one above the other, and the panel 1 of the dried material follows a path that has a serpentine shape. In this case, the fans 7 are located between the air-permeable transport tapes 4 and produce circular air streams 8 that hit the surface of the material being dried facing the fans, t; E. About the internal and external.

Since each of the two vertical rows of fans 7 is limited by an air-permeable conveyor belt 4 on both sides, and since the fans themselves, like the device of FIG. 1-4 are also arranged in rows, and the wings of two adjacent fans are mounted in opposite directions, two circular air streams are created, of which one is directed upwards and the other downwards.

Cross bars 9 serve in; this embodiment of the dryer only in order to protect the dried material from take-off under the action of ventilating air and to be guides to the cloth in those places, where the tape of the dried material does not pass between the two conveyor belts.

The subject of the patent.

A device for drying, aging (oxidation) or carbonization of a fibrous material, consisting of a chamber passed through a Drying Mat; 7 with a common drive shaft for each row located above or. under the tape of the material being dried, or on both sides of it, working so that each pair of adjacent fans blows air in parallel directions with respect to the axes of their drive shafts.
