Cyclic heating device for cloth roller of beam dyeing machine

Abstract

The present invention discloses a loop heating device for a cloth roller of a jig dyeing machine. The invention is characterized in that the device comprises a cloth roller ring-shaped water jacket inside a cloth roller body, water inlet jackets and revolving back water jackets are respectively arranged at the two sides of the cloth roller body and at the outer circumference of a roll shaft, a water inlet shaft head hole which is used to connect the cloth roller ring-shaped water jacket and water inlet jacket is arranged on the roll shaft of the cloth roller, the water inlet jacket is connected with a water inlet tube, the revolving back water jacket is connected with a back water tube, the water inlet tube and the back water tube are connected with a tank which can contain circulating water, a pump is arranged on the water inlet tube, a steam inlet tube enters the tank, a steam inlet control valve is arranged on the steam inlet tube, a temperature sensor is arranged inside the tank and is connected with a computer by a lead. The loop heating device for the cloth roller of the jig dyeing machine solves the problem that temperature difference exists between the cloth roller and the dyeing solution, thus 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 circulating heating device for a cloth roll of a jig dyeing machine, 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 20 kg of dye liquor (most of which is water, and water accounts for about 99.98% of the dye liquor) to dye. The dyeing bath ratio of the jig dyeing machine is only about 1:3, and the lowest is less than 1:2. Compared with the overflow jet dyeing machine, it can save a lot of energy consumption, which mainly consists of the consumption of coal, electricity and water. The dyeing wastewate...

AI Technical Summary

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 below 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.
