Background technology
Dyeing is high energy consumption, high pollution industry, and therefore, the dyeing machine of exploitation low energy consumption, low emission is the manufacturing target of dyeing machine.The dye bath ratio of overflow jet dyeing machine commonly used is about 1:20, promptly 1 kilogram of cloth (fabric) will (wherein the overwhelming majority be a water with 20 kilograms of dye liquors, water accounts for dye liquor and is about 99.98%) dye, and the dye bath ratio of dye jigger has only about 1:3, minimum reaching below the 1:2, compare with overflow jet dyeing machine, can save a large amount of energy consumptions, wherein be mainly coal,, the consumption of water. dyeing waste discharging simultaneously has only about 1/10th of overflow jet dyeing machine, it is a kind of dyeing machine of energy-conservation and environmental protection, but also there is deficiency in dye jigger, mainly is aberration problem end to end, and this is with different relevant with fabric each several part dyeing temperature in the dyeing once, mainly be that two cloth beams are above dye liquor, it is lower than dye liquor temperature all the time, and dyeing temperature is high more, and the temperature difference at dye liquor and cloth beam place is big more, it is lower than other place that it makes batching on the winding up roller press close to the cloth temperature of winding up roller part, the cloth color of pressing close to winding up roller so shoals gradually, causes whole dyed cloth middle dark, the situation that two is shallow.
Summary of the invention
Technical problem to be solved by this invention provides a kind of heater that can improve the cloth roller of beam dyeing machine temperature.
For solving the problems of the technologies described above, the invention provides a kind of steam heating device for cloth roller of beam dyeing machine, it is characterized in that: comprise the cloth beam ring-shaped heating cavity that is positioned at the cloth beam enclosure, be respectively arranged with steam admission swivel joint and steam back-steam swivel joint in the both sides of cloth beam shell, on the cloth beam inner core, have a steam admission opening that can connect cloth beam ring-shaped heating cavity and steam admission swivel joint, on the cloth beam inner core, have a steam exhaust hole that can connect cloth beam ring-shaped heating cavity and steam admission swivel joint, the steam admission passage links to each other with steam admission swivel joint, and steam back-steam pipeline and steam back-steam swivel joint join; Also comprise the control system that is used to measure the cloth beam skin temperature and controls the quantity of steam that enters the cloth beam ring-shaped heating cavity according to the cloth beam skin temperature.
Described control system is: be pressed on temperature sensor on the end face of cloth beam shell and be connected to by the temperature signal lead and be positioned at first copper ring and second copper ring that is enclosed within cloth beam inner core one end, between reaching, the both sides of first copper ring and second copper ring are respectively equipped with first insulating washer, second insulating washer and the 3rd insulating washer, the periphery that first copper ring and second copper ring are set at the cloth beam inner core is provided with insulating bushing, axle head at the cloth beam inner core is provided with the tight parts of retaining, first carbon brush slidably contacts with second copper ring with first copper ring respectively with second carbon brush, first carbon brush and second carbon brush by lead with temperature signal reach can control computer according to the temperature signal steam regulation throttle flow that is obtained in.
The beneficial effect that the present invention reached:
Steam heating device for cloth roller of beam dyeing machine of the present invention has the cloth beam ring-shaped heating cavity that is positioned at the cloth beam enclosure, the control computer enters the steam throttle flow of cloth beam ring-shaped heating cavity according to the temperature conditions control of measured cloth beam shell, the temperature that guarantees the cloth beam shell thus is consistent with dye liquor temperature, solved the problem that there are the temperature difference in cloth beam and dye liquor, the stub bar tail aberration of dying cloth is eliminated.
The specific embodiment
