Description

Heat Shrinkable Clothes Dryer {A CLOTHES DRYER TO HEAT SHRINK}

The present invention is a heat to minimize the decrease in tensile strength by easily adjusting the overfeed of the fabric paper on the screen belt conveyor by arranging the nozzle to form a continuous air flow at the same time on the upper and lower surfaces of the fabric paper moved by the screen belt conveyor Shrink type clothes dryer.

In general, in the various processes performed during the production of the fiber, the fibers that are dyed and printed are wetted by the dye solution, so that the fibers are quickly dried and shrunk using a hot air drying apparatus, and then transferred to the next process.

As a device for carrying out the drying process, a tenter is mainly used to perform a drying process and a shrinkage process by heat treatment. The inner temperature of the tenter during processing of the fiber fabric is 180 In the state maintained at 220 degrees in the state, high-speed and high-temperature hot air has been supplied to the fiber fabric through the nozzle, and the fiber fabric has been processed as desired.

In connection with the above technique, a dryer is disclosed in Korean Patent Publication No. 94-6246. The configuration of the driving motor M is provided on one side of the lower side of the rectangular chamber 1 having a substantially rectangular parallelepiped shape, as shown in FIGS. 1A and 1B. The blower fan 3 is fixed to the motor shaft 2 of this drive motor M. As shown in FIG.

Here, the blowing fan 3 is a fan (Fan) is formed so as to be blown in a direction perpendicular to the suction direction of the air.

In addition, a radiator R or a gas burner may be provided at a lower side of the rectangular chamber 1 corresponding to the opposite side on which the driving motor M is installed, as a radiator for performing heat exchange with the flowed air.

Between the radiator R and the blowing fan 3 of the driving motor M, a duct member 4 through which air flows is fixed, and one end thereof is installed to surround the entire blowing fan 3. When the blowing fan 3 is rotated by the driving motor M, the heat passing through the radiator R serves to guide suction flow to the blowing fan 3 in the direction of the arrow.
