Description

Drying machines for drying fibrous materials are known, including a drying chamber with two tape mesh transnorters arranged inside it for clamping and transporting the fibrous material formed into the canvas, two rows of rollers to support and clamp the mesh conveyors to one another and a number of nozzles for blowing hot air through the material.

The described drying machine differs from the known ones in that the drying chamber is made in the form of a cylindrical drum, inside which the working branches of the mesh conveyors and supporting rollers are arranged in concentric circles, and the non-operating branches of the conveyors are located outside the drying chamber, deflecting several directional rollers; blow nozzles are located but ok | 5izhiosti, concentric working branches m mesh conveyors. This feature of the dryer allows to intensify the drying process and reduce the size of the machine.

To enter the drying chamber and exit the layer of fibrous material from it, the upper part of the drying chamber is provided with nozzles arranged at an angle to the vertical pipe installed in the upper part of the chamber for partial removal of gas with water vapor.

The drawing shows a drying machine.

The machine is a drying chamber /, made in a) 5 kind of a cylindrical drum, inside of which the working branches of two mesh conveyors 2 and 3 and two rows of rollers 4 and 5 supporting them holding are mounted on concentric circles. The non-working branches of conveyors. 2 and 5 are located outside the drying chamber 7. Inside No. 127989-- 2 -

Measures on the outer surface of the conveyor 3 are arranged nozzles 6 through which hot gas is supplied to the material being dried.

The mesh conveyors 2 and 3, together with the fibrous material sandwiched between them, divide chamber 1 into two parts: the outer annular part 7 and the inner cylindrical part 8. In part 7 of the chamber there is an outlet 9 for supplying hot gas, and part 8 of the chamber communicates a pipe 10 for partial removal of exhaust gas saturated with water vapor. Two nozzles 11 and 12 are arranged at an angle to the pipe 10, through which the mesh conveyors 2 and 3 with the Yulochny material pass at the entrance to the chamber / and exit from it.

The layer of fibrous material pressed by the rollers 13 and sandwiched between the mesh conveyors 2 and 3 is last fed into the chamber /. Conveyors are driven by rooms 14 and supported by two rows of rollers 4 and 5. When passing inside the chamber, the fibrous material is blown with hot gas supplied to part 7 of the chamber through nozzle 9 and exiting nozzles 6. When blown with hot gas, the fibrous material is dried, and the exhaust gas, saturated with water vapor, is discharged through pipe 10.

Songs of such mangins can be installed in one unit.

Claims (2)

1. Drying machine for drying fibrous materials, incorporating a drying camera with two double-sided wire mesh conveyors inside it for clamping and transporting the fibrous material formed into a canvas, two rows of rollers to support and clamp one wire conveyor to another, and a series of nozzles for blowing hot air through a material, characterized in that, in order to intensify the process, to reduce the dimensions of the map, the chamber is made in the form of a cylindrical drum, inside which The working branches of the mesh conveyors and their supporting rollers are located on coherent centric circles, and the non-operating branches of the conveyors are located outside the drying chamber, bending around several guide rollers, etc.) than the blowing nozzles are arranged in a circle concentric with the mesh conveyors. 2. The machine according to claim 1, wherein it is necessary that in order to enter the drying chamber and exit the layer of fibrous material from it, the upper part of the nesting chamber is provided with nozzles angled to the mounted in the upper part chambers vertical pipe for partial removal of gas saturated with water vapor.
