Description

Technical Field

[0001] The invention belongs to the technical field of polyester fiber spinning, and particularly relates to a polyester fiber spinning device and a processing method thereof. Background Technique

[0002] The polyester fiber spinning device is a core device in chemical fiber production, which is used to extrude molten polyester (PET) through precision spinneret holes, and form continuous fibers after cooling and stretching. The working principle of the polyester fiber spinning device is to extrude the molten PET raw material through the micropores of the spinneret plate to form a fiber stream, and then make continuous fibers through cooling and solidification and stretching orientation. The whole process realizes the transformation from polymer melt to high-performance fiber by precisely controlling temperature, pressure and draw ratio.

[0003] In the existing polyester fiber spinning device, during use, due to solid impurities in the material and carbonization factors at high temperature, the spinneret holes of the spinneret plate are blocked inside after long-term use. At present, for the blockage treatment inside the spinneret holes, it is usually necessary to disassemble and clean each mesh hole one by one. And because some blockages are nested tightly in the inner wall of the spinneret holes, when directly flushing and unblocking from the upper and lower parts, there are still problems that some blockages cannot be completely cleaned. The comprehensive unblocking is difficult and the effect is poor. And affected by the blockage of the spinneret holes, the size of the limit wire obtained by spinning does not meet the requirements, the product quality declines, and the comprehensive use effect is not good.

[0014] A processing method of a polyester fiber spinning device includes the following processing steps: First step: The metering pump quantitatively pumps the molten material into the conveying assembly, and introduces it into the upper half spinneret plate through the distribution assembly, and sprays downward along the lower half spinneret plate to complete spinning. At the same time, the bottom air-cooling and heat-dissipating part is started to complete rapid spinning and cooling; Second step: When clogging needs to be cleared, external flushing water is input into the inlet pipe and injected into the conduction chamber surrounded by the distribution assembly, the distribution connection part, the support plate and the upper half spinneret plate. The flushing liquid in this chamber enters the distribution connection part. The power part is started to control the deflection of the lower half spinneret plate, and the upper holes and the lower holes are staggered.

[0016] (2) By using the dynamically filtering part that is properly fitted between the power part and the distribution component, after the spinning process for a period of time, the power part drives the dynamically filtering part to rotate, and relative scraping occurs in the distribution component, scraping the impurities filtered at the top of the dynamically filtering part to a unified place, avoiding large-scale blockage of the filter net and causing unstable spinning, and improving the spinning effect.

[0017] (3) By using the power part and the sealing control component, when flushing water is introduced, the sealing control component opens the top port, and at the same time, the distribution connection part seals the interior, enabling the flushing water to conduct to the lower part of the dynamically filtering part and performing backwashing on the dynamically filtering part upward in a narrow space.

10. A processing method of a polyester fiber spinning device according to any one of claims 1-9, characterized in that: It includes the following processing steps: The first step: The metering pump (2) quantitatively pumps the molten material into the conveying assembly (3), and introduces it into the upper half spinneret plate (4) through the distribution assembly (6), and sprays downward along the lower half spinneret plate (5) to complete spinning. At the same time, the bottom air-cooling and heat-dissipating part is started to complete rapid spinning and cooling; Step 2: When clogging removal is required, input the external flushing water into the inlet pipe (10), and inject it into the conduction chamber formed by the distribution component (6), the distribution connection part (8), the support plate (9), and the upper spinneret plate (4). The flushing liquid in this chamber enters the distribution connection part (8). Start the power part (7), control the deflection of the lower spinneret plate (5), and make the upper holes (42) and the lower holes (52) stagger. The flushing water introduced into the spinneret assembly enters the first annular cavity (45) and the second annular cavity (55), and then enters the first fitting groove (43) and the second fitting groove (53). Then, it sprays outwards from the inside of the spinneret assembly through the upper holes (42) and the lower holes (52) respectively, and the clogging removal is completed from the inside to the outside. Step 3: After a period of spinning, pause the spinning, and start the power part (7) to drive the rotation of the dynamically fixed dynamic filtration part (11) on the outside. The dynamic filtration part (11) rotates in the distribution component (6), and the top filter is scraped, and the filter is concentrated and piled up at one place on the top of the dynamic filtration part (11). Step 4: When cleaning water is introduced into the inlet pipe (10), keep the inside of the distribution connection part (8) closed, and start the seal control component (12) to move downwards to open the top port (63) inside the distribution component (6), so that the flushing water enters the top port (63). Start the power part (7) again to drive the rotation of the dynamic filtration part (11), and automatically backflush the dynamic filtration part (11) from the bottom.
