Cyclic heating device for cloth roller of beam dyeing machine

Abstract

The invention discloses a loop heating system for a cloth roller of a jig dyeing machine. The invention is characterized in that the heating system comprises a cloth roller ring-shaped water jacket inside the cloth roller body, water inlet jackets and rotatable backwater jackets are respectively at the two sides of the cloth roller body and the outer circumference of a roll shaft, a water inlet shaft head hole which is used for connecting the cloth roller ring-shaped water jacket and the water inlet jacket is arranged on the roll shaft of the cloth roller, a water inlet hole which is used forconnecting the cloth roller ring-shaped water jacket and the rotatable backwater jackets is also arranged on the roll shaft of the cloth roller, the water inlet jacket is connected with a water inlettube, the rotatable backwater jacket is connected with a backwater tube, the other end of the backwater tube is connected with a heat exchanger which is connected with a water pump, the outlet of thewater pump is connected with the water inlet tube. The heating system of the invention can heat the cloth roller, thus solving the problem of temperature difference between the cloth roller and the dye solution, eliminating color deviation between the initial dyeing of the cloth and the final dyeing of the cloth.

Description

technical field [0001] The invention relates to a circulation heating device for a cloth rolling roller of a dyeing jigger, which belongs to the textile printing and dyeing machinery industry. Background technique [0002] The printing and dyeing industry is an industry with high energy consumption and high pollution. Therefore, the development of dyeing machines with low energy consumption and low emissions is the goal of the printing and dyeing machinery manufacturing industry. The dyeing bath ratio of the commonly used overflow jet dyeing machine is about 1:20, that is, 1 kg of cloth (fabric) needs to be dyed with 20 kg of dye solution (most of which is water, and water accounts for about 99.98% of the dye solution). The dyeing bath ratio of the jigger is only about 1:3, and the lowest can be less than 1:2. Compared with the overflow jet dyeing machine, it can save a lot of energy consumption, mainly coal, electricity, and water consumption. At the same time Dyeing sewag...

Problems solved by technology

The dyeing bath ratio of the commonly used overflow jet dyeing machine is about 1:20, that is, 1 kg of cloth (fabric) needs to be dyed with 20 kg of dye solution (most of which is water, and water accounts for about 99.98% of the dye solution). The dyeing bath ratio of the jigger is only about 1:3, and the lowest can be less than 1:2. Compared with the overflow jet dyeing machine, it can save a lot of energy consumption, mainly coal, electricity, and water consumption. At the same time Dyeing sewage discharge is only about one-tenth of the overflow jet dyeing machine. It is an energy-saving and environmentally friendly dyeing machine. Part of the dyeing temperature is different, mainly because the two cloth rollers are above the dye liquor, which is always lower than the temperature of the dye liquor. The higher the dyeing temperature, the greater the temperature difference between the dye liquor and the cloth rollers, which makes the cloth on the rollers The temperature of the cloth close to the roll is lower than that of other places, so the color of the cloth close to the roll gradually becomes lighter, resulting in a situation where the entire dyed fabric is dark in the middle and light at both ends.
