Dyeing liquid heating arrangement for dyeing machine

Abstract

The invention discloses a device for heating dyeing liquid of a dyeing machine by a heat conductive oil. The heating device includes a heat exchanger and a dyeing crock. Wherein the heat exchanger is composed of a cylindric housing, a tube plate, and several heat exchanging pipes. Structure characteristics of the heating device are that an oil boiler, an oil outlet of the oil boiler is communicated with an inlet on the cylindric housing of the heat exchanger via an oil pump, an oil inlet valve and an oil pipe, an outlet on the cylindric housing is communicated with an oil inlet of the oil boiler via an oil outlet valve and the oil pipe, thereby a closed circular oil path is formed betwee the oil boiler and the cylindric housing. The dyeing liquid passing through the heat exchanging pipes are heated by the heat conductive oil entered into the cylindric housing. The dyeing liquid is heated by the dyeing liquid heating device for a dyeing machine, thereby energy sources can be saved, using cost is reduced, and lift time of the device can be prolonged.

Description

(1) Technical field [0001] The invention relates to a heating device. Specifically, it is a heating device that uses heat transfer oil to heat the dyeing liquid used on the dyeing machine. It is suitable for heating the dyeing solution in the printing and dyeing industry. (2) Background technology [0002] At present, in the printing and dyeing industry, the heaters used to heat the dyeing solution are steam heaters. This steam heater contains a heat exchanger, which is composed of a cylindrical shell, a tube sheet and several heat exchange tubes. The two ends of the cylindrical shell have a medium inlet and a medium outlet respectively. Said tube sheet and heat exchange tubes are located in the cylindrical shell. Among them, there are two tube plates, and they respectively leave a space between the two ends of the inner cavity of the cylindrical shell, and their surroundings are sealed with the inner wall of the cylindrical shell, and a number of through holes are corre...

AI Technical Summary

Problems solved by technology

The large temperature difference will cause destructive factors such as impact on the equipment, thereby shortening the service life of the equipment;

[0004] The 2nd, because the steam that enters cylindrical casing is directly discharged from the outlet of cylindrical casing in vain after heating the heat exchange tube, it can only be used once, not only the utilization rate of heat is low (usually only about 35%) , and a serious waste of water resources;

[0005] The third is waste of energy and high cost of use
