Water vapor separator and uniform heating pipe of jig dyeing machine heating system

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 7 and 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.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing machinery, and is suitable for the heating system of the jigger in the textile bleaching and dyeing industry. Background technique [0002] At present, the common dyeing jiggers in the market are M125, DC dyeing machine, and AC dyeing machine. The machine occupies a small area and is suitable for small batches and multi-variety fabric trial production and production. It meets the current market demand and is welcomed by bleaching and dyeing manufacturers. However, the heating systems of jiggers currently produced at home and abroad are complicated, and the waste of steam and water is serious. There are four disadvantages when heating directly into the dyeing tank: First, the steam contains a large amount of water and is absorbed by the dye solution, making the fabric easy to dry.

However, at present, the heating system of dyeing jiggers produced at home and abroad is complicated, and the waste of steam and water is serious. There are four disadvantages when heating directly into the dyeing tank: First, the steam contains a large amount of water and is absorbed by the dyeing liquid, making the fabric easy to dry. Inhomogeneous dyeing occurs; the second is that the waste of water vapor with the insulation pipe is serious, it is always in the state of steam, no matter what the operator does, the insulation pipe is turned on, and the hot water flows into the sewer through the vegetable water valve; the third is direct heating , when heating from one end of the dyeing tank to the other, the size and pressure of the steam ejected from the steam pipe holes are different, resulting in uneven temperature around the dyeing tank, which will inevitably lead to uneven dyeing; It is impossible to ensure the temperature in the dyeing tank by using the temperature of the pipe. You can only open the air valve to add steam, and there is no way to solve the problem if there is water.
