Heating circulating system of jig dyeing machine

Abstract

The invention discloses a design method of a heating circulating system of a jig dyeing machine and belongs to the technical field of dyeing machinery. According to the design method, the heating circulating system of the jig dyeing machine is composed of, as shown in figure 1, a vertical type steam separating drum (1), an automatic ventilation valve (2), a manual control valve (3), a master valve (4), a drainage valve (5), a circulating water recycling tank (6), a hydraulic pump (7), a heating tube (8), a dye vat (9) and a steam inlet pipe (10). The heating circulating system achieves accurate technological parameters, solves the problem of uneven dyeing due to moisture absorption of dye liquor, ensures the dyeing effects, makes full use of circulating water, saves steam water, is simple in structure, convenient to maintain and low in cost, improves the dyeing quality and efficiency, omits thermal preservation pipes, thermal preservation layers or the like, avoids pollution and achieves circulation of airflow.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing machinery, and relates to a dyeing jigger and a thermal cycle system thereof. In particular, it is a heating circulation system of a dyeing jigger. Background technique [0002] At present, some heating systems are used: direct heating tubes, heat preservation pipes, heat preservation layers, etc. The disadvantages: when heating, the steam contains water, causing the dyeing liquor to absorb moisture, the process parameters are not accurate, and the phenomenon of uneven dyeing occurs, which wastes steam water. Serious, unfavorable for energy saving and consumption reduction. Although some systems of Seagull avoid the above shortcomings, they cannot recycle water vapor. The common jiggers in the market include M125, DC jigger, AC jigger, etc., which are suitable for small batches.

Problems solved by technology

[0002] At present, some heating systems are used: direct heating tubes, heat preservation pipes, heat preservation layers, etc. The disadvantages: when heating, the steam contains water, causing the dyeing liquor to absorb moisture, the process parameters are not accurate, and the phenomenon of uneven dyeing occurs, which wastes steam water. Serious, unfavorable for energy saving and consumption reduction. Although some systems of Seagull avoid the above shortcomings, they cannot recycle water vapor. The common jiggers in the market include M125, DC jigger, AC jigger, etc., which are suitable for small batches. The trial production and production of various fabrics meet the current market demand and are welcomed by bleaching and dyeing manufacturers

But at present, the jiggers produced at home and abroad are seriously wasting steam and water. They all adopt the method of heating directly into the dye tank, which causes the following harms. The fabric is prone to uneven dyeing; 2. The waste of water vapor is serious with the heat preservation pipe, which is always in the state of steam. No matter what the operator does, the heat preservation pipe is turned on and the hot water flows into the sewer through the vegetable water valve; 3. Directly Heating, heating from one end of the dyeing tank to the other end, the size and pressure of the steam ejected from the steam pipe hole are different, making the surrounding temperature uneven, which will lead to uneven dyeing; 4. The most worrying about low temperature in dyeing, only rely on the heat preservation pipe It is not possible to ensure the temperature in the dyeing tank by temperature. You can only open the air valve to add steam, and there is no way to solve the problem if there is water.
