Abstract

The invention discloses a cloth dyeing machine. The cloth dyeing machine comprises a dye vat, a cloth lifting device and a dye liquor circulating system, the dye liquor circulating system comprises a water return pipe, a charge pump, a heat exchanger and a dye liquor feed cylinder, the dye liquor feed cylinder is connected with the water return pipe, a liquor inlet of the water return pipe is connected with a dye liquor outlet in the lower part of the dye vat, a liquor outlet of the water return pipe is connected with a dye liquor inlet in the upper part of the dye vat through the charge pump, a heat exchange pipe of the heat exchanger is mounted in the water return pipe, and both a steam inlet and a water outlet of the heat exchanger are formed on the same side of the heat exchanger and are fixed on one side of the water return pipe through flanges. Through mounting the heat exchanger in the water return pipe, the temperature difference is reduced, the dyeing water ratio is lowered, the cloth can be dyed uniformly in the dye liquor at uniform temperature so as to avoid dyeing defects and stripes, and the dyeing quality is improved; in the whole process of dyeing, the heat exchanger is always soaked in the dye liquor, the heat loss is reduced, and the expansion and contraction mechanical stress of the heat exchanger due to the temperature change is lowered.

Description

A kind of textile dyeing machinery

Technical field

The present invention relates to field of printing and dyeing, relate in particular to a kind of textile dyeing machinery.

Background technology

Along with the fast development in textile dyeing machinery market, associated core production technology application will become the focus of enterprises pay attention in the industry with research and development, understand research and development trend, process equipment, technology application and the trend of domestic and international textile dyeing machinery production core technology for enterprise's improving product technical specification, improve the market competitiveness very crucial.

Please refer to shown in Fig. 1, the dye liquor circulatory system of textile dyeing machinery in the market generally comprises return pipe 12, charge pump 13, heat exchanger 14 and dye liquor barrel, the inlet of return pipe 12 is connected with the dye liquor outlet of dye vat 11 bottoms, the liquid outlet of return pipe 12 is connected with heat exchanger 14, dye liquor barrel is connected with charge pump 13, charge pump 13 is connected with heat exchanger, this kind of structural configuration, dye liquor in dye liquor in return pipe 12 and dye liquor barrel is after charge pump 13 pumps to heat exchanger 14 heats, the dye liquor temperature of the dye liquor temperature of heat exchanger 14 liquid outlets and dye vat 11 bottoms differs greatly, easily produce look flower and striped, dyeing quality can not be guaranteed, and heat exchanger 14 is exposed in air, heat runs off larger.

Summary of the invention

The object of the invention is to for the problems referred to above, a kind of textile dyeing machinery is provided, differ greatly with the heat exchanger liquid outlet dye liquor temperature of the textile dyeing machinery on solution existing market and the dye liquor temperature of dye vat bottom, easily produce look flower and striped, the problem that dyeing quality can not be guaranteed, and heat exchanger is exposed in air, the heat larger problem that runs off.

The object of the invention is to be achieved through the following technical solutions:

A kind of textile dyeing machinery, comprise dye vat, put forward cloth apparatus and the dye liquor circulatory system, the described dye liquor circulatory system comprises return pipe, charge pump, heat exchanger and dye liquor barrel, described dye liquor barrel is connected with return pipe, the inlet of described return pipe is connected with the dye liquor outlet of dye vat bottom, the liquid outlet of return pipe is connected with the dye liquor import on dye vat top by charge pump, the heat exchanger tube of described heat exchanger is built in return pipe, and the air intake of heat exchanger, delivery port are all arranged at a side of heat exchanger, and be fixed on a side of return pipe by flange.

As preferred version of the present invention, described heat exchanger is tubular heat exchanger or U-shaped pipe heat exchanger.

As preferred version of the present invention, the opposite side of described heat exchanger is movably connected in return pipe.

As preferred version of the present invention, in described return pipe, be fixed with orifice plate, on described orifice plate, have pin-and-hole, in described pin-and-hole, be movably provided with removable pin, one end of described removable pin is connected with heat exchanger.

As preferred version of the present invention, described removable pin is connected with Welding of Heat-exchanger.

Beneficial effect of the present invention is, described textile dyeing machinery is by being built in heat exchanger in return pipe, thereby reduce the temperature difference, reduce dyeing water ratio, cloth can evenly be painted in the uniform dye liquor of temperature, thereby avoid look flower, the generation of striped, improve dyeing quality, and in whole dyeing course, heat exchanger is all immersed in dye liquor, reduce heat loss, reduce the mechanical stress of expanding with heat and contract with cold that heat exchanger answers variations in temperature to bring, in addition, one end of heat exchanger is flexibly connected with return pipe, make at high temperature retractable of heat exchanger, having solved original heat exchanger is subject to the pipeline restriction cannot free-extension, flimsy problem after the mechanical stress of being expanded with heat and contract with cold.
