Vacuum pump, which extracts air from it, reducing the air inlet to the boiler, ujenn reached a predetermined temperature therein

is murder, the guide gradual diminution

of the air inlet while the inlet and

Outlet temperature is kept the same, reducing the pressure in the boiler to lower the boiling temperature of the water contained therein and that Maintaining this pressure until the outlet and inlet temperatures of the air are predetermined Remains constant for a period of time.

Description of further features of the innovation.

It shows:

Figure 1 is an elevation of the yarn dryer, the one

lYl machine illustrated with a drying boiler, Figure 2 is a plan view of the same,

Figure 3 is a schematic elevation showing a number of drying kettles.

A yarn drying boiler A of known construction is provided with a suction pipe 1 which is connected to a Vacuum pump 2 is connected and with a feed pipe 3 which opens into the open at 4 and a heating battery 5 zuiischen the inlet of the second tube 3 and the known boiler A has.

The drying is carried out in two stages: (

The bales of thread B on one or more frames J ^ are used in the known manner in the drying boiler. With the lock or lid open _a Air is sucked into the boiler, which is denser at ambient temperature, and therefore this is done the pad B absorbed UJasser by the force of the air drawn through it, rather than by removing it the air absorption of moisture.

The second stage comprises closing the closure or lid a_ of the drying kettle and exposing the bales B to heated air, which is sucked in through the second pipe 3 via the heating battery 5. A probe S is provided in the pipe 1, a second probe in the pipe 3 and a third probe B in the vessel A.

When the temperature of the unloaded from the boiler Air is equal to the inlet temperature, a valve 9 is gradually closed to the air inlet to throttle and a predetermined vacuum ujird created in the boiler, so that the in the bale remaining moisture evaporates and in this state is sucked off by the vacuum pump 2, uias uniform drying of all bales results.

The negative pressure in the drying vessel A is controlled according to the dried yarn.

For example, evaporation of moisture is a yarn that is to be dried at 93.3 ⁰ C (2oo F), a vacuum of 164.7 mm (6 1/2 inches) Hg effect that the with the heated air from Boiler is pulled. The yarn is dry when the outlet and inlet temperatures indicated by the probes 6 and 7 in the kettle remain constant.

Thus, if the outlet temperature increases with the inlet temperature matches, the yarn drying vessel A is subjected to a vacuum. This allows the Boiling point of water to the outlet temperature

(i.e. the higher the temperature, the lower the vacuum, the lower the temperature, the higher the vacuum), so that all remaining moisture evaporates and evaporates in this The mold is removed by the vacuum pump 2.

The vacuum pump 2 is driven by a motor 11 and the discharge from the pump continues ") a separator 12 to remove the moisture from it

the air being expelled from the separator through a muffler 21

In operation, this is the case with the lid open Yarn drying boiler A contaminated by the pump 2 withdrawn water by soap or other impurities and a valve 13 is opened to allow the water to drain. When the lid _a closed is murdered, the withdrawn water is fed to a storage container in which the valve 13 is switched to close the process.

The tubes 1 and 3 are each provided with a further valve 18 and 19, respectively.

lUeitare tubes 14 and 15 are provided, the
connect the pipe 1 with dam pipe 3 and each
are provided with a valve 16 and 17, so that by closing the valves 18 and 19 and
by opening the valves 16 and 17, the direction of flow of the air through the yarn drying kettle A can be reversed. The valves are operated by motor or manually.

The pump 2 operates a number of vessels A, - _;

as shown in Figure 3, or a number of pumps are used.
