Description

Technical Field

[0001] The utility model relates to the technical field of acid dye production equipment, in particular to a water washing mechanism for acid dye slurry. Background Technique

[0002] Acid dyes refer to dyes containing acidic groups in the dye molecule, also known as anionic dyes, which can combine with amino groups in protein fiber molecules through ionic bonds and are applicable under acidic, weakly acidic or neutral conditions. They are mainly azo and anthraquinone structures, and a few are arylmethane structures. Dyes and colors generally have their own colors and can make other substances obtain bright and firm colors in molecular state or dispersed state.

[0003] When producing acid dyes, before the dehydration and drying steps, it is necessary to wash the acid dye slurry to remove impurities. However, the existing water washing simply adds the washing liquid directly into the slurry, which will cause the washing liquid and the slurry not to be fully mixed, thus affecting the quality of the dried dye.

[0004] To solve the above problems, this case was born. Content of the Utility Model

[0019] The present utility model will be further described in detail below with reference to the drawings and embodiments.

[0020] An embodiment of the present utility model provides an acidic dye slurry water washing mechanism, as Figure 1-2 shown, including a water washing tube. The water washing tube includes an inner tube 1 and an outer tube 2. The outer tube 2 is sleeved outside the inner tube 1. The bottom of the inner tube 1 is not closed, and the bottom of the outer tube 2 is closed. The inner tube 1 and the outer tube 2 are slidably connected. The inner tube 1 is fixed. In Figure 1 the attached Figure 2 drawings, the left sides are all in the state when the water outlet holes I 5 and II 6 overlap, that is, when the water washing operation is carried out, and the right sides are all in the state when the water washing operation is not carried out.

[0021] A plurality of first clamping rings 3 are fixedly arranged on the outer wall of the inner tube 1, and a plurality of second clamping rings 4 are fixedly arranged on the inner wall of the outer tube 2. The first clamping rings 3 and the second clamping rings 4 correspond to block and prevent the outer tube 2 and the inner tube 1 from slipping off. By introducing the washing liquid into the inner tube 1, the outer tube 2 is moved downward.

[0022] Reference appendix Figure 2 On the inner tube 1, a first water outlet hole 5 is provided. The first water outlet hole 5 is arranged between each group of first clamping rings 3. On the outer tube 2, a second water outlet hole 6 is provided. The second water outlet hole 6 is arranged between each group of second clamping rings 4. The first water outlet hole 5 and the second water outlet hole 6 correspond to each other one by one and have the same height. The height of the first water outlet hole 5 and the second water outlet hole 6 is less than the thickness of the first clamping ring 3. When the water washing operation is not carried out, the first clamping ring 3 completely blocks the second water outlet hole 6.

[0023] Reference appendix Figure 2 The inner tube 1 passes through the top of the outer tube 2. A fixing ring 7 is provided below the top of the outer tube 2. The fixing ring 7 is fixedly connected to the inner tube. Between the fixing ring 7 and the top of the outer tube 2, a plurality of springs 8 are provided. The plurality of springs 8 are equally spaced around the inner tube 1. When the washing liquid is pressurized and introduced into the inner tube 1, the bottom of the outer tube 2 is subjected to pressure, the springs 8 are stretched, the first water outlet hole 5 and the second water outlet hole 6 coincide, and the washing liquid rushes out from the second water outlet hole 6. When the introduction of the washing liquid stops, the bottom of the outer tube 2 is no longer pressured, and under the action of the springs 8, the outer tube 2 retracts, and the first clamping ring 3 completely blocks the second water outlet hole 6.

[0024] Reference appendix Figure 1-2 On the part of the inner tube 1 passing through the outer tube 2, a plurality of limiting blocks 9 are fixedly arranged at equal intervals around it. The top of the outer tube 2 is connected with a limiting ring 10. The limiting ring 10 is engaged with the limiting blocks 9 and can slide up and down. The engagement between the limiting ring 10 and the limiting blocks 9 prevents rotational sliding between the inner tube 1 and the outer tube 2.
