Description

Technical Field

[0001] This application relates to the field of dyeing and printing equipment technology, and more specifically, to a rinsing and boiling machine. Background Technology

[0002] Flax, with its breathable and moisture-wicking properties, is widely used in the textile industry. Flax is conventionally spun using wet spinning, a process that includes a scouring and bleaching step, typically performed using a scouring and bleaching machine. This machine improves the separation of flax fibers. Flax scouring and bleaching is an important textile process, its main purpose being to remove non-cellulose substances such as lignin, pectin, and hemicellulose from flax fibers, thereby increasing fiber splitting and spinnability. This process not only improves yarn quality but also enhances its whiteness and breaking strength.

[0003] In existing technologies, flax scouring and bleaching processes typically employ a large shell containing a yarn rack and flax yarn. A heating device is installed inside the shell to heat the liquid during the scouring and bleaching process. However, this equipment cannot effectively squeeze and degumm the flax during scouring and bleaching, resulting in poor degumming effects. Specifically, patent CN218345679U discloses a flax yarn scouring and bleaching device. By using a water storage tank and a scouring and bleaching tank, the device can rotate the liquid within the tank during scouring and bleaching, increasing the scouring and bleaching speed. After drainage, the increased rotation speed further dehydrates the flax yarn. Furthermore, the use of a mesh cover and a take-up plate allows for squeezing the flax yarn within the mesh cover during scouring and bleaching, maximizing the removal of gluten and improving the scouring and bleaching effect.

[0004] In practical applications, the flax yarn after boiling and bleaching is dehydrated directly without rinsing, which affects its internal cleanliness. At the same time, the centrifugal dehydration method has a complex structure and the entire device lacks a protective cover, which poses a potential danger. In addition, during the boiling and bleaching process, the bleaching water contains a large amount of non-cellulose substances such as lignin, pectin and hemicellulose, which cannot be discharged in time, affecting the efficiency of subsequent separation. Therefore, there is an urgent need for a boiling and bleaching machine to solve the above problems. Summary of the Invention

[0032] The agitation unit also includes a scraper 8, which cooperates with the inner wall of the scouring hood 2 to clean the inner wall of the scouring hood 2 and prevent scale buildup on the inner wall of the hood.

[0033] In use, the invention first uses a controller to control the second cylinder 4 to move the rinsing hood 2 upwards, adding flax from the top of the rinsing tank 1 into the inner telescopic box 10. Then, the second cylinder 4 moves the rinsing hood 2 downwards, sealing the top of the rinsing tank 1. Next, the heating box 21 is opened to add hot water into the inner telescopic box 10. The first cylinder 11 squeezes the inner telescopic box 10, increasing the separation speed. Simultaneously, the second rotary motor 18 separates the movable side plate 17. This process is repeated to continuously squeeze the flax. After squeezing, the controller controls the hydraulic cylinder 12 to operate, causing the lifting plate 15 to descend. The cleaning water is discharged into the rinsing tank 1 and discharged from the outlet pipe 3. Then, the hydraulic cylinder 12 controls the lifting plate 15 to rise. After the hydraulic cylinder 12 drives the inner telescopic box 10 to rise, the depth of the stirring rod 7 in the inner telescopic box 10 changes. The heating box 21 adds hot water to the inner telescopic box 10 again. The first rotary motor 5 drives the stirring rod 7 to rotate. After the stirring is completed, the hydraulic cylinder 12 drives the inner telescopic box 10 to move down. Then, the first air cylinder 11 squeezes the inner telescopic box 10 again. This process is repeated. At the same time, the first rotary motor 5 drives the scraper 8 to rotate, thereby cleaning the inner wall of the rinsing hood 2 and preventing scale buildup on the inner wall of the hood.
