Description

Tension-free overflow washing tank

(1) Technical field

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

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 situation of energy saving and emission reduction. At the same time, there are also knitting cylinder and open-width double-drum washing machines that can be combined with multiple units to form a combined machine for continuous production, high washing efficiency, and low energy consumption that have been popularized in recent years. However, in this washing process, the fabric is in direct contact with the surface of the drum and is easily scratched, 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.

(3) Contents of the invention

The object of the present invention is to overcome the above disadvantages and provide a tension-free overflow water washing box which is not easy to scratch the fabric surface, does not produce wear marks, cleans thoroughly and consumes less water.

The purpose of the present invention is achieved in this way: a tension-free overflow water washing box, including a box body and a drum, the drum has two pieces, and the two drums are arranged in parallel in the box body, one on the left and one on the right. The body is provided with a water inlet, a water outlet and an overflow port. The drum is placed in the lower half of the box, and a cloth passing roller is arranged in the box above the two drums. A spraying device is arranged in the box; the drum includes an outer net cylinder and an inner drum, the inner drum and the outer net drum are coaxially arranged inside and outside, and the outer edge of the inner drum is axially arranged with a plurality of ribs , the rotation direction of the outer net drum and the inner drum is opposite.

The tension-free overflow water washing box of the present invention, the cloth passing roller includes a cylinder body, the cylinder body includes rubber strips and connecting strips, and there are multiple rubber strips and connecting strips, and the circumferential direction of the multiple rubber strips and the multiple connecting strips is Arranged at intervals, two adjacent rubber strips are connected by connecting strips.

In the tension-free overflow washing tank of the present invention, the cross-section of the convex rib is an inverted "V" structure.

The beneficial effects of the present invention are:

The outer screen cylinder and the inner cylinder of the drum of the present invention rotate in opposite directions, and a spray device is arranged above the cloth passing roller to form an external spray and internal pressure drum structure; the outer edge of the inner drum is designed with ribs to ensure water cleaning effect. At the same time, the reverse rotation of the outer mesh drum and the inner drum will form a turbulent water film on the front and back sides of the washed fabric and the drum surface, which will accelerate the thinning and rupture of the impurity interface layer between the washed fabric surface and the washing liquid. , Finally, the impurities are replaced into the cleaning solution and washed away, which improves the washing efficiency. At the same time, the surface of the washed fabric in operation is not in direct contact with the surface of the drum, eliminating possible scratches and wear marks, and ensuring that the surface of the washed fabric is smooth and free of scratches. The rubber-strip-type cloth-passing roller can minimize the friction between the cloth and the cloth-passing roller surface, so that the cloth surface has no scratches and wear marks, and at the same time, the rubber-strip-type cloth-passing roller can cooperate to improve the washing effect. The cleaning liquid circulation filtration system formed by the water inlet on the box body, other water inlets, water outlets and overflow ports, etc., accelerates the circulation and filtration of the cleaning liquid in the box, eliminating the need to clean the lint in the box and ensuring smooth circulation, which greatly reduces The water consumption improves the cleaning effect. The cleaning liquid sprays the washed fabrics, and the cleaning effect is very good. The water in the box can also be heated to accelerate the molecular movement of water and impurities during washing, shortening the cleaning time.
