Description

The invention relates to devices for drying roll materials in suspension and can be used in the chemical, photochemical, paper industry for the manufacture of polymeric materials and paper.

The purpose of the invention is to reduce energy costs by intensifying the drying process.

In FIG. 1 shows a General view of the device; in FIG. 2 is a view A in FIG. 1.

The device for drying coil materials in suspension contains an air distribution box 1, an upper wall 2 and a side wall 3 with visors 4 and 5 bent inside the box 1, forming the front 6 and rear 7 forming walls of the slot nozzle 8. At the edge 9 of the rear recesses 10 are uniformly located on the forming wall 7. The air distribution duct 1 comprises a pipe 11 for supplying air supporting the web material 12 in suspension.

A device for drying coil materials in suspension is as follows. Air is supplied under pressure through the pipe 11 to the air distribution box 1. From the duct 1, air flows out through the slotted nozzle 8 between the front 6 and rear 7 forming walls, while the upper part of the air stream is subjected to the perturbation of the recesses 10. Next, the turbulent air stream flows in the gap between the upper wall 2 and the material 12, keeping the material 12 suspended condition and at the same time dries the material 12.

The location of the turbulizing element on the rear forming wall 7 of the slit nozzle 8 and its execution in the form of a series of recesses 10, evenly spaced on the edge 9 of the rear forming wall 7, allows to increase the turbulence of the upper part of the air stream, directly

in contact with the material 12. This helps to increase the heat transfer from the air flow to the dried material 12, the intensification of the drying process and reduce energy costs.
