Abstract
An energy-saving dyeing machine includes a body, a liquid dyes supply device, a liquid dyes heating device having a direct-heating heat exchanger, and a cooling unit connecting to the direct-heating heat exchanger by a series connection. When heating up the liquid dyes, the liquid dyes enters the direct-heating heat exchanger from the liquid dyes supply device via a supply tube, saving several heating procedures and unnecessary energy wastes. Additionally, an outer wall is surrounding the body to form a surrounding space for the heated exhaust gas from the direct-heating heat exchanger to enter and reheat the liquid dyes in the body again, making a better use of the heat energy.
Claims3
An energy-saving dyeing machine, comprising:
- a body having an entering port for liquid dyes arranged aside, connecting to an entering tube, and an exiting port for liquid dyes arranged at the other side, connecting to an exiting tube for liquid dyes circulation;
- a liquid dyes supply device arranged outside said body, including a pump for pressuring, an outlet connecting to a supply tube, and an inlet connecting to said exiting tube;
- a liquid dyes heating device arranged outside said body near the liquid dyes supply device, including a direct-heating heat exchanger to heat up liquid dyes, said direct-heating heat exchanger including an inner room having a heating room therein and an inner entry arranged aside, an intermediate room surrounding said inner room, defining a heat exchanging room with a first entry connecting to said supply tube and a first exit connecting to a series connected pipeline for discharging heated liquid dyes, an outer room surrounding said intermediate room, defining a discharging room with a exhaust gas outlet and including a plurality of connecting holes connecting through said heating room and an outer entry arranged corresponding to said inner entry, and a heating unit arranged at said outer entry to send in fuels into the heating room;
- and
- a cooling unit arranged outside said body near said liquid dyes heating device, including a heat exchanger to cool down liquid dyes, said heat exchanger having an entering port for liquid dyes connecting to an entry valve and a cooled water supply tube, an exiting port for liquid dyes connecting to an exit valve for discharging cooled water, a second entry connecting to said series connected pipeline, and a second exit connecting to said entering tube;
- whereby when heating up liquid dyes, the exit valve is closed and liquid dyes enter the direct-heating heat exchanger from the liquid dyes supply device via the supply tube for heating, then flow through the series connected pipeline and the cooling unit without cooling and flow into the body via the entering tube;
- while cooling down liquid dyes, the exit valve is opened and liquid dyes enter the direct-heating heat exchanger from the liquid dyes supply device via the supply tube without heating, then flow through the series connected pipeline into the heat exchanger for cooling, and flow into the body via the entering tube.
