Description

Technical Field

[0001] This utility model relates to the field of nozzle assembly technology, and more specifically, it relates to a filtration device for a spinneret assembly. Background Technology

[0002] The spinneret is the core component of the melt spinning machine. It consists of filter material, distribution plate, spinneret, and assembly sleeve. The spinning melt enters the assembly through the central feed hole, is filtered by the filter screen, and is evenly distributed to the spinneret by the distribution plate. The melt is then extruded into fibers through the spinneret holes. The assembly is fixed by a tight ring and sealed with an aluminum gasket to prevent leakage. Its core functions include filtering impurities, homogenizing melt viscosity, and evenly distributing melt.

[0003] When the spinning melt of the spinneret passes through the filter screen, it tends to flow into the assembly from the central feed hole, resulting in more melt flowing through the center and less along the edges. This uneven distribution of the spinning melt after passing through the filter screen makes the center of the screen prone to clogging. Furthermore, during the filtration of the spinning melt, metal sand or sea sand is often placed on the filter screen for preliminary filtration. When replacing the filter screen, all the metal sand and sea sand must be emptied and replaced with new filler, making replacement and cleaning very troublesome. Moreover, if the density of the metal sand and sea sand filler is different, it may affect the filtration effect of the filter screen.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In one possible embodiment, please refer to Figure 1 and Figure 2 As shown, a filtration device for a spinneret assembly includes a housing 1. A distribution head 2 connected to a discharge port is installed on the housing 1. The distribution head 2 is conical, and a flow equalization plate 3 is fixedly connected to the lower surface of the distribution head 2. By installing the distribution head 2 connected to the discharge port inside the housing 1, the spinning melt flows into the distribution head 2 after exiting the discharge port. Since the distribution head 2 is conical and the lower end of the distribution head 2 is fixedly connected to the flow equalization plate 3, the spinning melt entering the distribution head 2 will achieve the purpose of flow equalization under the action of the distribution head 2 and the flow equalization plate 3, so that the flow rate of the spinning melt from the middle and the outside is the same, and the distribution of the spinning melt is more uniform.

[0020] For further details, please refer to Figure 1 and Figure 2 As shown, the flow equalization plate 3 is provided with a plurality of perforations 301 arranged in a circular array, and the diameter of the perforations 301 increases sequentially from the center of the flow equalization plate 3 outwards, so that the spinning melt can more easily flow out from the larger diameter perforations 301 on the periphery, thereby increasing the flow rate of the spinning melt on the periphery and thus achieving the purpose of flow equalization.

[0021] For further details, please refer to Figure 1 and Figure 2As shown, a standardized first filter assembly 4, a second filter assembly 5, and a third filter assembly 6 are sequentially installed in the housing 1 below the feed head 2. A limiting device 7 for limiting the first filter assembly 4, the second filter assembly 5, and the third filter assembly 6 is fixedly connected inside the housing 1. The flow equalization plate 3 abuts against the first filter assembly 4. By installing the standardized first filter assembly 4, the second filter assembly 5, and the third filter assembly 6 inside the housing 1, the disassembly and installation of the filter assembly is more convenient and easier to clean. The standardized filter assembly makes the filter assembly pre-processed, which can ensure the filtration effect of the filter assembly and reduce the influence of human factors. At the same time, through multi-stage filtration, the filtration effect of the spinning melt is improved, the spinning is more uniform, and better quality fibers are generated.

[0022] For further details, please refer to Figure 1 and Figure 2 As shown, the limiting device 7 includes a first sliding groove 701, a circular groove 702, and a second sliding groove 703 disposed within the housing 1. The first sliding groove 701 and the second sliding groove 703 are both connected to the circular groove 702. The first sliding groove 701 and the second sliding groove 703 are arranged perpendicularly. The flow equalization plate 3, the first filter assembly 4, the second filter assembly 5, and the third filter assembly 6 are all provided with sliders 8. The sliders 8 are slidably engaged with the first sliding groove 701 and the second sliding groove 703, and are rotatably engaged with the circular groove 702. The housing 1 is rotatably connected above the circular groove 702 with symmetrically distributed limiting blocks 704. The limiting blocks 704 and the second sliding groove 703 are on the same straight line. The lower end of the first filter assembly 4 is provided with a limiting groove 401 that engages with the limiting block 704.

[0023] For details, please refer to Figure 1 and Figure 2 As shown, during installation, the third filter assembly 6 is installed first. The slider 8 of the third filter assembly 6 is aligned with the first slide groove 701 and slid into the housing 1. When the third filter assembly 6 slides to the circular groove 702, the slider 8 is rotated to align with the second slide groove 703 and then slide into the second slide groove 703, completing the installation of the third filter assembly 6. Next, the slider 8 of the second filter assembly 5 is aligned with the first slide groove and slid in until the slider 8 abuts against the circular groove 702, completing the installation of the second filter assembly 5. The limiting block 704 is flipped outward, and the slider 8 of the first filter assembly 4 is aligned with the first slide groove 701 and slid in until the limiting block 704 abuts against the limiting groove 401, completing the installation of the first filter assembly 4. Finally, the slider 8 of the flow equalization plate 3 is aligned with the first slide groove 701 and slid in until it abuts against the first filter assembly 4, thus completing the entire installation process of the filter assembly and the flow divider of the housing 1. The installation is simple and convenient.

[0024] For further details, please refer to Figure 1 and Figure 2As shown, the lower ends of the first filter assembly 4, the second filter assembly 5, and the third filter assembly 6 are all fixedly connected with sealing rings that abut against the inner wall of the housing 1, thereby ensuring the sealing between the first filter assembly 4, the second filter assembly 5, and the third filter assembly 6 and the housing 1. The first filter assembly 4 is filled with sea sand, the second filter assembly 5 is filled with metal sand, and the third filter assembly 6 is a high-mesh stainless steel woven mesh. The filtration effects of sea sand, metal sand, and high-mesh stainless steel woven mesh are superimposed in sequence, thereby achieving a better filtration effect. Moreover, the first filter assembly 4 filters out a large number of impurities, so when replacing it, usually only the first filter assembly 4 needs to be replaced, allowing the filter device to be replaced in a short time and speeding up production efficiency.
