Description

BASIC Auth. St. No. 120833 describes a dryer for fabrics, where the generator of the drying medium is located under the drying chamber.

The proposed dryer differs from that known in that the generator is straight-flowd and placed inside the chamber, and the gas burners have manifolds with loose-fitting perforated plates for the drying medium AND a pipeline to supply air to the burners after cooling the heated fabric in the outlet of the dryer .

In addition, in the nozzle-blowing zones, additional rollers are installed for the return movement of the fabric in the drying chamber.

These differences create a positive effect, since they intensify the drying process, reduce the size, “increase the processing time of the fabric.

FIG. 1 schematically shows a dryer in longitudinal section; in fig. 2-pelvic burner in cross section.

In the dryer (see Fig. 1), the fabric passes through the drying zones /, //, ///, then, returning by the rollers, passes over the collector 2 along the partition 3 into the exit zone IV to the self-storage unit 4. External air enters the dryer through the adjustable louvered grill 5, cooling the fabric in zone JV, then through duct 6. passes between gas burners 7, located under zone 8 rollers /, into the generator of the drying medium 9. In the generator, the outside air mixes with the combustion products and enters the zone / then through the partition 10 into the zone // for heating her drying environment from the zone / through the window 11.

Part of the drying medium from the /// zone through window 12 also enters the // zone for recycling.

No. 151289-2. From the zone, the drying medium through the filter 18 is sucked into a common duct (not shown in the drawing). The recirculation fans 14 inject the drying medium into the collector 2, from where it enters the nozzle chambers 15 with calibrated nozzles and 16, of which the fabric is blown over the entire width.

Through the opening 17, a portion of the spent drying medium is removed from the dryer. Each of the burners 7 (see Fig. 2) is a collector 18 with combined gas-air mixture openings, some of which are made in the form of slots 19, and some are circular holes 20. In the burner, a copper grid 21 is installed to protect it from proskoka flame in the collector / 5 and removable plate 22.

Claims (3)

1. Drying cloth for fabrics containing a drying chamber with zones of nozzle blowing and an ejector generator of a drying medium with gas burners, according to the author. St. No. 120833, characterized in that, in order to intensify the drying process and reduce the size, the generator is straight-through and placed inside the drying chamber. 2. Dryer according to claim 1, characterized in that the gas burners have manifolds with perforated strips for passing through the drying medium and a pipeline for supplying air to the burners after cooling the heated fabric in the outlet zone of the dryer. 3. Dryer according to claim 1, characterized in that, in order to increase the processing time of the fabric, additional rollers are installed in the zones of nozzle blowing for returning the fabric in the drying chamber. tvo 18 20
