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.
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.
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.
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.
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.
