Description

Technical Field

[0001] The utility model belongs to the technical field of dyeing, in particular to an energy-saving device for dyeing cotton fabrics. Background Art

[0002] The process of changing the color of textiles is called dyeing, which is achieved by physical adsorption or chemical reaction of dyes with fibers, or by the formation of insoluble coloring substances directly on the fibers, giving the textiles the desired color.

[0003] The current dyeing system relies on directly heating the dye bath to increase the temperature. However, this method encounters several challenges: first, due to the poor flow properties of the dye bath, the heat distribution is uneven. When applied to cotton fabrics, it will cause inconsistent color penetration, which will affect the color uniformity of the final product and lower the quality standard. Second, this heating mode consumes extremely high energy, which correspondingly increases production costs.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with specific implementation methods.

[0020] In the following description, all concepts related to directionality (or orientation) such as up, down, left, right, front and back are with reference to the position state of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be understood as special limitations on the technical solution provided by the utility model.

[0021] like Figure 1 and Figure 2 As shown, a cotton fabric dyeing energy-saving device comprises a dyeing kettle 1, a first liquid inlet pipe 2 and a first liquid outlet pipe are arranged on the side wall of the dyeing kettle 1, a nozzle 21 is arranged on one end of the first liquid inlet pipe 2 extending into the dyeing kettle 1, a first valve 22 is arranged on the first liquid inlet pipe 2, and a second valve is arranged on the first liquid outlet pipe.

[0022] An opening 3 is provided on the top of the dyeing kettle 1; a stirring motor 4 is also provided on the top of the dyeing kettle 1, a rotating rod 5 is provided on one side of the stirring motor 4, the rotating rod 5 is arranged throughout the dyeing kettle 1, and a stirring member 6 is provided on the rotating rod 5 arranged in the dyeing kettle 1; a circulation pipe 7 and a heat exchange mechanism 8 communicated with the circulation pipe 7 are provided on the dyeing kettle 1.

[0023] The heat exchange mechanism 8 includes a heat exchange space 81 and a plurality of branch pipes 82 arranged in the heat exchange space 81, the plurality of branch pipes 82 are connected to the circulation pipe 7, and the heat exchange mechanism 8 is provided with a second liquid inlet pipe 83 and a second liquid outlet pipe 84, both of which are connected to the heat exchange space 81. The second liquid inlet pipe 83 is provided with a third valve 85, and the second liquid outlet pipe 84 is provided with a fourth valve 86. The circulation pipe 7 is provided with a circulation pump 71.

[0024] The stirring member 6 includes a plurality of first stirring members 61 and a plurality of second stirring members 62, and the first stirring members 61 and the second stirring members 62 are both frame-shaped structures. The first stirring members 61 and the second stirring members 62 are arranged at intervals, and the frame shape of the first stirring member 61 is larger than the frame shape of the second stirring member 62. The stirring members 6 arranged in this way can stir the cotton fabric and the dyeing liquid in the dyeing kettle 1 more fully, and the dyeing effect is better.

[0025] Here’s how it works:

[0026] First, put the cotton fabric through the opening 3, then open the first valve 22, input the dye liquid through the first liquid inlet pipe 2, and then drive the stirring motor 4 to drive the first stirring member 61 and the second stirring member 62 to rotate. Since the cotton fabric will rotate with the stirring member 6 in the dyeing kettle 1, and the nozzle 21 on the first liquid inlet pipe 2 is facing the stirring member 6, the cotton fabric on the stirring member 6 can be preliminarily sprayed.

[0027] After a certain amount of dye liquid is input, the first valve 22 is closed, the circulation pump 71, the third valve 85 and the fourth valve 86 are opened, and steam (or other heating liquid) is transported to the heat exchange space 81 in the heat exchange mechanism 8 through the second liquid inlet pipe 83 to exchange heat with the dye liquid in the plurality of branch pipes 82 in the heat exchange space 81, that is, the dye liquid is circulated and heated to reduce the color difference caused by uneven heating of the dye liquid. The steam after heat exchange will become water and be discharged through the second liquid outlet pipe 84 (the same applies to other heated dye liquids).

[0028] After a period of stirring and dyeing, the stirring motor 4, the first valve 22, the third valve 85, the fourth valve 86 and the circulation pump 71 are turned off, and the cotton fabric is taken out from the opening 3. If the dyeing liquid needs to be replaced, the second valve on the first liquid outlet pipe is opened to discharge the dyeing liquid in the dyeing kettle 1, and the replaced dyeing liquid is re-input through the first liquid inlet pipe 2, and the above steps are repeated; if the dyeing liquid does not need to be replaced, the dyeing liquid can be continuously circulated and heated.

[0029] The present application provides a heat exchange mechanism 8 and a stirring element 6 to improve the fluidity of the dye solution and uniformly heat it, so that the color penetration of the cotton fabric in the reaction kettle is consistent, thereby ensuring product quality. At the same time, it achieves the purposes of energy saving (no need to use a heating device to directly heat the dye solution in the dyeing kettle 1) and reducing production costs.

[0030] The above content is a further detailed description of the technical solution provided in combination with the preferred implementation methods of this patent. It cannot be determined that the specific implementation of the utility model is limited to the above descriptions. For ordinary technicians in the technical field to which this patent belongs, without departing from the concept of this patent, they can also make several simple deductions or substitutions, which should be deemed to fall within the scope of protection of this patent.
