Abstract

The invention relates to a jig dyeing machine heating system in the technical field of printing and dyeing machinery. A direct heating pipe, a heat insulation pipe, a heat insulation layer and the like are adopted in the current heating system to cause the defects that: because the steam contains water during heating, the dye solution absorbs moisture, the process parameter is not accurate, the dyeing is not uniform, the steam water is seriously wasted, and the heating system is not favorable for energy conservation and consumption reduction. By adopting the principle that the water is on the lower part and the steam is on the upper part in a vertical steam pocket 1, the water is downwards drained through a drain valve 5 for recycle 6; the steam is upwards heated from a steam inlet pipe 7and a heating pipe 8 by a pneumatic film valve 2 or a manual stop valve 3; the steam returned to a dye jar is pure steam so as not to affect dyeing; the temperature should be preserved during dyeing; a temperature control valve 2 automatically supplies and stops the steam so as to solve the problems of water carried in heating and moisture absorption of the dyeing solution and ensure the dyeing effect; if the heat insulation pipe or the heat insulation layer is adopted, the steam is wasted, and the manufacturing cost is increased; and the heating system has simple structure, reduces the maintenance, lowers the manufacturing cost, and saves the steam and the water.

Summary of the invention

To the problems referred to above, the present invention adopts novel transmission structure, improve heating and energy-conservation aspect following three characteristics are arranged: the one; Superheated steam is a principle from top to bottom to the source of dye jigger, and the present invention increases a three-dimensional steam and separates bag, and what heat to staining bath at the logical vapour of drum upper end perforate is pure steam; Anhydrous; What the steam trap outflow was loaded onto in perforate under drum is hot water, and this is a principle of utilizing vapour pressure, separates steam automatically; The staining bath temperature can be provided with back heating automatically according to technological requirement, has avoided the waste of steam, because anhydrous entering staining bath heating in the steam pipe need not be worried the dye liquor moisture absorption, has guaranteed Color, the purpose of practicing thrift steam.Aspect machine-building: reduced the input of insulating tube, cell body perforate welding, heat-insulation layer cost of manufacture, reduced production cost, improved economic benefit.The 2nd, steam separates on the height that bag is installed in 500mm overhead, and hot water can flow into recycling in the tank of insulation dye vat under naturally, utilizes circulating pump to squeeze in the cylinder during rinsing.This measure hot water is recycled, and has played the purpose of practicing thrift steam again.The 3rd, the heating in the staining bath since in the middle of adopting admission to both sides simultaneously multiple spot disperse superheated steam, impel no temperature dead angle in the groove, temperature even, solved a dyeing temperature difficult problem.

The course of work of the present invention is: at first, the operator opens total stop valve, and steam gets into and divides drum heating entering that state is set, according to technological requirement; Be provided with temperature requiredly, automatic temperature-controlled valve is opened, because gas from top to bottom, below being pressed in the hot water that contains in the superheated steam; The steam that returns up flows into the staining bath heating, owing to be temp autocontrolled, no matter when heats; Do not influence dyeing, Here it is, need how much steam just what to be used, not waste.The second, it is that 2 steam inlet pipes get into from the centre and disperse simultaneously to both sides that steam gets into staining bath, and the heating tube around impelling goes out vapour simultaneously, has guaranteed that staining bath does not have the uneven temperature dead angle.Or else need artificial excellent stirring of using, with the circulating pump circulating fluid, can practice thrift a large amount of steam, the 3rd, get into the water that divides drum and pass through drain valve inflow insulation recovery pond naturally, during rinsing, squeeze into staining bath with circulating pump and use.The present invention adopts water, vapour to separate, and evenly the heating compact has reduced the device fabrication cost, has reduced maintenance of equipment work amount, has thoroughly solved and can not directly heat the drawback of dyeing.

The present invention is described in further detail below in conjunction with accompanying drawing:
