Tension-free overflow water washing tank

Abstract

The invention relates to a tension-free overflow water washing tank, which is mainly applicable to water washing and dyeing of pure cotton and cotton and polyester blended fabric after cold pad-batch pretreatment, stacking and steaming, and water washing after printing. The tension-free overflow water washing tank comprises a tank body (1) and rotary drums (2), the number of the rotary drums (2) is two, the two rotary drums (2) are arranged at the left and the right in the tank body (1) in parallel, and the tension-free overflow water washing tank is characterized in that a water inlet (1.2), a water outlet (1.7) and an overflow port (1.3) are arranged on the tank body, the rotary drums (2) are arranged at the lower half part in the tank body (1), a cloth-crossing roller (3) is arranged in the tank body (1) above the two rotary drums (2), and a spraying device (5) is arranged above the cloth-crossing roller (3) and the right rotary drum (2) in the tank body (1); and each rotary drum (2) comprises an outer mesh cylinder (2.2) and inner mesh cylinder (2.3) which are coaxially arranged at the interior and the exterior, a plurality of convex edges (2.5) are axially arranged on the outer edge of each inner rotary cylinder (2.3), and the rotation directions of the outer mesh cylinders (2.2) and the inner rotary cylinders (2.3) are reverse. The adoption of the water washing tank has the advantages of being difficult to scratch the surface of the fabric, not producing grinding marks and having thorough and good cleaning effect.

Description

(1) Technical field [0001] The invention relates to a washing box. It is mainly suitable for washing, dyeing, and washing after printing of pure cotton and polyester-cotton blended fabrics before cold pad batching and steaming. It belongs to the technical field of textile printing and dyeing machinery. (2) Background technology [0002] At present, most of the washing water treatment of textile printing and dyeing adopts the traditional intermittent production mode, that is, it is carried out step by step on the rope overflow dyeing machine. The washing process of the rope dyeing machine adopts a tank-by-tank washing method, that is, one tank is washed one tank at a time, and the water is in a circulating state and meets at the nozzle during washing. The cleaning process takes a long time, the efficiency is not high, and the water consumption is large. This washing method can no longer meet the needs of printing and dyeing plants for washing equipment under the new situat...

AI Technical Summary

Problems solved by technology

However, in this washing treatment method, the direct contact between the fabric and the surface of the drum is easy to be scratched during the washing process, and the fabric is cleaned on one side during the washing process. The washing effect of the fabric is poor, the cleaning is not thorough, and the water consumption is also large.
