Description

TECHNICAL FIELD

[0001] The present application relates to the field of padding equipment, in particular to a dye liquor recovery device of a padding machine. BACKGROUND

[0002] In the traditional padding process of cotton textiles with reactive dyes, there are problems such as low dyeing rate and fixation rate of reactive dyes. In actual production, the accuracy of the sample is low, the sample time is long, the operation is complicated, a large amount of steam is used, and the sewage discharge is large. The semi-finished product has high requirements. The fixation rate of early X-type reactive dyes is only 50% to 60%. In the 1990s, multi-active reactive dyes were developed, and the fixation rate was only about 80%. Not only the amount of dyes is increased, but also the cost is large. Therefore, in the traditional reactive dyeing padding process, a large amount of inorganic salt (salt or sodium sulfate, the amount is generally 150g / L to 200g / L) must be added. The discharge of high-salt printing and dyeing wastewater destroys the ecological environment of water. The high permeability of salt leads to salinization of the soil around rivers and lakes, reducing the yield of crops. Therefore, how to improve the dyeing rate of reactive dyes and reduce or not use salt during dyeing is a subject that people have been studying.

The discharging mechanism includes a squeeze roller group rotatably connected to the rack, a driving motor, and an adjusting assembly. The squeeze roller group includes a first squeeze roller and a second squeeze roller. The recovery mechanism includes a recovery tank installed on the rack along the direction of fabric transportation and a filter plate installed on the recovery tank along the width direction of the fabric. During use, the dye liquor squeezed out by the squeeze roller group drops into the recovery tank, and the dye liquor passes through the filter plate to reduce impurities in the dye liquor.

[0004] According to the related technology, impurities are easy to accumulate on one side of the filter plate, which may block the filter plate and affect the filtering efficiency. Practical new type content
