Description
(a) TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to an assisting heat exchanger
and a direct temperature rise/lowering device for use with an
ultra-low liquor ratio dyeing machine, and in particular to an
assisting heat exchanger that is additionally installed in a dyeing
machine without increase of liquid or water consumption (liquor
ratio) such that the assisting heat exchanger that is structured to
use a pumping pipe as a heat exchange pipe serve as an auxiliary or
secondary heat exchanger of the dyeing machine. In addition, the
present invention also provides a direct temperature rise/lowing
device that is mounted to a predetermined location in the dyeing
machine so that in conducting a washing operation of a dyeing bath
of the dyeing machine, steam may be fast introduced therein to fast
increase the temperature of water used to wash a dying bath and in
an attempt to lower down the temperature of the dyeing bath, cold
water is fast introduced to cause a quick drop of the temperature
of the dyeing bath so as to provide an assisting temperature
rise/lowering device for washing the dyeing bath of the dyeing
machine.
(b) DESCRIPTION OF THE PRIOR ART
[0002] A conventional ultra-low liquor ratio dyeing machine is
often installed with a small-sized heat exchanger due to low liquor
ratio and small liquid amount used, in order to reduce the amount
of water consumed. However, temperature rise or lowering is often
slow when fast increase or decrease of temperature (such as for
washing a dyeing bath) is needed and this would affect the
efficiency of operation.
SUMMARY OF THE INVENTION
[0003] The primary objective of the present invention is to provide
an assisting heat exchanger that helps increases the rate of
increasing/decreasing a temperature of a dyeing machine and
improves operation efficiency but does not requires an increase of
the amount of water (liquor ratio) used. Another objective of the
present invention is to provide a direct temperature rise/lowering
device that assists the performance of a heat exchanger to achieve
fast increase or decrease of a temperature of water that is used to
wash a dyeing bath of a dyeing machine in order to shorten the time
period required for washing the dyeing bath.
[0004] The feature of the present invention is that an external
pipe is additionally mounted to an inlet port or an outlet port or
both inlet and outlet ports of a pump of an ultra-low liquid ratio
dyeing machine and is mounted with inlet and outlet openings for
seam and cooling water so that additionally mounted external pipe
may be structured as a housing of a heat exchanger to function as a
typical heat exchanger to increase the rate of increasing or
decreasing a temperature but without increasing the amount of water
(liquor) used in the dyeing machine.
[0005] In this way, an existing pump pipe can be used as a heat
exchange pipe of a heat changer to form a typical heat exchanger
that might serve as an auxiliary or secondary heat exchanger, and
additionally, a direct temperature rise/lowering device may be
mounted in a dyeing bath of a dyeing machine at a predetermined
location so that steam may be directly introduced into a dyeing
bath in washing the dyeing bath in order to directly heat washing
water so that the cleaning liquid can be quickly increased of the
temperature thereof to improve washing performance and shorten
washing time, and cold water may be alternatively introduced in an
attempt to lower down the temperature of the dyeing bath so that
quick lowering of temperature of the dyeing bath may be
achieved.
[0006] The foregoing objectives and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention
itself, all of which will become apparent to those skilled in the
art, the following detailed description of the invention and the
claims should be read in conjunction with the accompanying
drawings. Throughout the specification and drawings identical
reference numerals refer to identical or similar parts.
[0007] Many other advantages and features of the present invention
will become manifest to those versed in the art upon making
reference to the detailed description and the accompanying sheets
of drawings in which a preferred structural embodiment
incorporating the principles of the present invention is shown by
way of illustrative example.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 is a schematic view showing a structure of a dyeing
machine according to an embodiment the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] The following descriptions are exemplary embodiments only,
and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0010] As shown in FIG. 1, the present invention provides an
assisting heat exchanger and a direct temperature rise/lowering
device for an ultra-low liquor ratio dyeing machine that comprises
a machine body 1 and a dyeing tube 8 arranged above the machine
body 1 to allow fabric to move therethrough. The dyeing tube 8 is
provided therein with a fabric seam detectors 5 that is set at a
predetermined location to detect a leading edger or seam of the
fabric. The machine body 1 is provided, in an interior space
thereof, with a nozzle 4 and a fabric guide roller 3 arranged at an
upper portion of a front end thereof. The machine body 1 is
provided with a liquid storage tank 6 that is mounted to a bottom
of the machine body at a rear end thereof. The liquid storage tank
6 is provided with a primary heat exchanger 12 arranged therein. In
an alternative arrangement, the primary heat exchanger 12 may be
mounted to a pipe 9 for circulation of dye. The liquid storage tank
6 is connected, at a bottom thereof, through a pipe 13 to a pump 7.
The pump 7 has an inlet port and an outlet port and an external
pipe 101 is additionally mounted to encompass the pipe 9 at the
inlet port or the outlet port of the pump and comprises a steam
inlet opening 113, a cooling water inlet opening 114, and a cooling
water outlet opening 115 mounted thereto. The additionally mounted
external pipe 101 may serve as a housing or external casing of a
heat exchanger to help increase the rate of increasing or
decreasing a temperature but does not require an increase of the
amount of water (liquor ratio) consumed by or involved in the
operation of the dyeing machine. In this way, the pipe 9 of the
pump 7 may serve as a heat exchange pipe of the heat exchanger to
thereby form a typical heat exchanger, which functions as an
assisting heat exchanger 10. Preferably, valves for controlling
ingress and egress of steam and cooling water for the assisting
heat exchanger 10 are shared with the primary heat exchanger 12 of
the dyeing machine in order to simplify the overall structure and
save cost. Further, the present invention also involves a direct
temperature rise/lowering device 11 that is mounted in a dyeing
bath 1-1 inside the machine body 1 at a predetermined location.
When washing the dyeing bath 1-1 is required, steam may be
introduced through a steam pipe 111 to cause a direct temperature
rise of washing water so that the temperature of the washing water
may be quickly increased thereby shortening the washing time. When
temperature drop is required form the dyeing bath 1-1, cold water
may be introduced through a cold water pipe 112 so that the
temperature the dyeing bath 1-1 can be lowered down quickly.
[0011] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0012] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the claims of the present invention.
