Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of flax processing, and particularly relates to a rotating washing type flax yarn scouring and bleaching device and a scouring and bleaching method thereof. BACKGROUND

[0002] At present, flax fabrics are widely applied due to the characteristics of moisture absorption, good air permeability, quick heat dissipation, bacterium inhibition and no static electricity. Since the flax roving contains a large amount of gum components, the fiber separation degree is poor, and the spinnability is poor. In order to improve the spinnability, the roving is often chemically scoured and degummed in production to remove part of pectin, hemicellulose, lignin and other gums, so that the fiber bundle in the roving is broken into finer fibers, thereby improving the fiber splitting degree, so as to process high-count yarn and high-grade products. When the existing flax yarn is scoured and bleached, the scoured and bleached pith, pectin and attached matters are often suspended in the scouring and bleaching solution. After the scouring and bleaching are completed, when the flax yarn is directly taken out, the suspended impurities are attached to the surface of the flax yarn, or when the scouring and bleaching solution is first pumped out and then the yarn is taken out, the impurities are often also attached to the surface of the flax yarn. Therefore, subsequent treatment is still needed after the flax yarn is taken out, and the processing is very inconvenient. Therefore, the existing structure and process need to be upgraded and modified, so that the taken-out flax yarn is clean and neat. SUMMARY

A spray cylinder 6 is installed in the middle of the positioning plate 4, spraying liquid to both sides. A filter screen 31 is provided inside the replacement chamber 3. Plate 31 divides the interior of the replacement chamber 3 into an upper filtration chamber 32 and a liquid storage chamber 33. The filtration chamber 32 is connected to the lower side of the interior of the boiling chamber 21 via a suction pipe 321. The liquid storage chamber 33 is connected to the lower end of the spray cylinder 6 via a drain pipe 331. The control mechanism 7 is installed in the drive chamber 22. The control mechanism 7 drives the two sleeve posts 5 to rotate synchronously. The lower part of the sleeve post 5 is provided with a lower support ring 51. The upper end of the sleeve post 5 is provided with a screw thread cap 52. The lower support ring 51 and the screw thread cap 52 form a positioning interval. A suction space 23 is left between the lower side of the lower support ring 51 and the bottom of the boiling chamber 21.

[0022] like Figs. 1 to 4 As shown, to facilitate rotation control of the sleeve post 5, the control mechanism 7 further includes a rotating sprocket 71, a rotating motor 72, a drive sprocket 73, and a transmission chain 74; the lower end of the sleeve post 5 extends into the drive cavity 22, and the lower end of the sleeve post 5 is connected to the rotating sprocket 71 respectively; the rotating motor 72 is installed on one side below the drive cavity 22, and the upper end of the rotating motor 72 is connected to the drive sprocket 73, and the drive sprocket 73 is engaged with the two rotating sprockets 71 through the transmission chain 74.

[0023] like Figs. 1 to 4 As shown, in order to ensure the stable rotational connection of the sleeve post 5 to the positioning plate 4 and to guarantee the sealing, a rotational locking channel 41 is further provided on the positioning plate 4; a rotational locking ring 53 is provided around the lower part of the sleeve post 5; the sleeve post 5 and the rotational locking ring 53 are rotatably locked onto the rotational locking channel 41; a sealing ring 411 is provided inside the rotational locking channel 41; the outer sides of the sleeve post 5 are rotatably and sealingly connected to the sealing ring 411.

[0024] like Figs. 1 to 4 As shown, in order to facilitate the input of solution into the spray cylinder 6, the lower end of the spray cylinder 6 extends downward from the positioning plate 4 into the drive cavity 22. The lower end of the spray cylinder 6 is provided with a connecting pipe 61, and the lower end of the connecting pipe 61 passes through the transmission chain 74 and is connected to the end of the drain pipe 331.

[0025] like Figs. 1 to 4As shown, for drainage control, the drainage pipe 331 is further equipped with a drainage pump and a solenoid valve; the suction pipe 321 is equipped with a suction pump. For convenient spray cleaning, multiple spray heads 62 are evenly arranged from top to bottom on both sides of the spray cylinder 6. Furthermore, the upper end of the boiling / bleaching tank 2 is equipped with an opening / closing cover 24.

[0026] like Figs. 1 to 4 As shown, a bleaching method for a rotary rinsing flax yarn bleaching device includes the following steps: S1. Attach the flax yarn roll to the sleeve post 5, and lock it by rotating the screw cap 52. Then inject the bleaching solution into the bleaching chamber 21 for bleaching.

[0027] S2. After the rinsing is completed, the rinsing solution in the rinsing chamber 21 is drawn through the suction pipe 321, so that the rinsing solution enters the filter chamber 32 of the replacement box 3 for filtration. After filtration, the rinsing solution is stored in the storage chamber 33.

[0028] S3. When the solution level in the bleaching chamber 21 reaches the lower support ring 51, the solution in the storage chamber 33 is transported into the spray cylinder 6 through the drain pipe 331. At the same time, the control mechanism 7 drives the two connecting columns 5 and the flax yarn on them to rotate synchronously. In this way, the bleaching solution is sprayed out through both sides of the spray cylinder 6 and washes the flax yarn on the connecting columns 5 on both sides, so that the impurities on the flax yarn are washed off and then filtered by suction pipe 321.

[0029] S4. After rinsing is complete, the suction pipe 321 stops suctioning, and the solution in the storage chamber 33 is completely transferred into the scouring chamber 21 through the drain pipe 331. Finally, the flax yarn is taken out.
