Description

Technical Field

[0001] This utility model relates to the field of PET production technology, and more specifically, to a filtration device for high-temperature resistant PET production and processing. Background Technology

[0002] The filtration device used in the production and processing of high-temperature resistant PET works by using the synergistic effect of physical barrier, inertial separation, structural optimization and automated design to efficiently filter impurities in high-temperature resistant PET raw materials, while improving ease of operation and production stability.

[0003] In existing published literature, patent publication number CN221734252U discloses a processing device for PET production. This technology requires the PET on top of the filter plate to be moved and cleaned through a filter plate cleaning structure. However, in actual use, the horizontal plate on the filter plate cleaning mechanism is prone to scraping against the filter holes on the filter plate during cleaning, resulting in damage to the filter plate. This makes it inconvenient for users to remove the cleaned PET from the processing device, reducing the convenience of using it in PET processing. However, this technology also has the following drawbacks.

[0004] In the production process of high-temperature resistant PET, it is necessary to first select PET particles of qualified size and separate PET particles with larger diameters to avoid clogging the processing area. However, during filtration, due to the large amount of PET particles, it is difficult to achieve simultaneous internal and external filtration, resulting in a small filtration area and low filtration efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a filtration device for high-temperature resistant PET production and processing, comprising a mounting plate, a drive shaft rotatably mounted on the inner wall of the mounting plate, a motor mounted at the top of the drive shaft for driving the drive shaft to rotate, and an inner and outer filtration assembly at the bottom of the drive shaft for synchronous filtration of PET particles, the inner and outer filtration assembly comprising: An inner filter barrel is fixed to the bottom end of the drive shaft.

The spacer cylinder is fixed on the outer wall of the top of the inner filter barrel; Multiple linkage bars are fixed to the top of the spacer cylinder, and an outer polygonal cylinder is fixedly connected to the outer wall of the spacer cylinder; Multiple outer holes are all located on the inner wall of the outer polygonal cylinder. Multiple bottom holes are all located at the bottom of the inner wall of the outer polygonal cylinder.

[0006] In a preferred embodiment, the center point of the drive shaft and the center point of the inner filter barrel are on the same vertical line, and the bottom cross-sectional shape of the inner filter barrel is circular.

[0007] In a preferred embodiment, the bottom cross-sectional shape of the outer polygonal cylinder is polygonal, and the top of the inner filter barrel is rounded.

[0008] In a preferred embodiment, the plurality of linkage bars are fixedly connected to the outer polygonal cylinder, and the plurality of linkage bars are arranged in a circumferential distribution.

[0009] In a preferred embodiment, a support frame is provided on one side of the motor, and both the motor and the mounting plate are fixedly connected to the support frame.

[0010] In a preferred embodiment, a dispersion strip is fixed to the outer wall of the drive shaft and below the mounting sleeve plate, and a plurality of linkage blocks are fixedly connected to the lower surface of the dispersion strip, and the linkage blocks are fixedly connected to the linkage strip. Each of the linkage bars has a movable bar fixedly connected to one end, and a slider is fixedly attached to the top of the movable bar. A slide rail is installed on the outer wall of the slider, and the slide rail is fixedly connected to the mounting plate. The slide rail is used to guide the slider to slide.

[0011] In a preferred embodiment, a plurality of the linkage blocks are arranged in a circular distribution, and the linkage blocks are perpendicular to the linkage bar.

[0012] In a preferred embodiment, the lower surface of the slider has a circular arc cross-sectional shape, and the slide rail has a circular arc cross-sectional shape.

[0013] The technical effects and advantages of this utility model are as follows: This invention utilizes internal and external filtration components to place high-temperature resistant PET particles inside an outer polygonal cylinder and an inner filter barrel.

A linkage bar rotates the outer polygonal cylinder, achieving large-area rotational filtration through multiple outer side holes and outer bottom holes inside the outer polygonal cylinder. This allows for large-area filtration of the high-temperature resistant PET particles both internally and externally, resulting in a wider filtration area and higher filtration efficiency.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figure 1 - Figure 4 The present invention relates to a filtration device for the production and processing of high-temperature resistant PET. The filtration device is provided with internal and external filtration components. The internal and external filtration components enable the high-temperature resistant PET particles to be filtered over a large area, resulting in a wider filtration area and higher filtration efficiency. The specific structural configuration of the internal and external filtration components is as follows.

[0022] Example 1: In this embodiment, as Figure 1 - Figure 3As shown, the assembly includes a mounting plate 1, with a drive shaft 2 rotatably mounted on the inner wall of the mounting plate 1. A motor 3 is mounted on the top of the drive shaft 2, driving the drive shaft 2 to rotate. The bottom of the drive shaft 2 is equipped with inner and outer filter components for synchronous filtration of PET particles. The inner and outer filter components include: an inner filter barrel 4, fixed to the bottom of the drive shaft 2, with multiple inner bottom holes 5 on its inner wall and multiple inner side holes 6 at its bottom; a spacer cylinder 17, fixed to the top outer wall of the inner filter barrel 4; multiple linkage bars 7, all fixed to the top of the spacer cylinder 17, with an outer polygonal cylinder 8 fixedly connected to the outer wall of the spacer cylinder 17; multiple outer side holes 9, all on the inner wall of the outer polygonal cylinder 8; and multiple outer bottom holes 10, all at the bottom of the inner wall of the outer polygonal cylinder 8. The center point of the drive shaft 2 and the center point of the inner filter barrel 4 are on the same vertical line, and the bottom cross-section of the inner filter barrel 4 is circular. The bottom cross-section of the outer polygonal cylinder 8 is polygonal, and the top of the inner filter barrel 4 is rounded. Multiple linkage bars 7 are fixedly connected to the outer polygonal cylinder 8, and the multiple linkage bars 7 are arranged in a circumferential distribution.

[0023] In this embodiment, as Figure 1 As shown, a support frame 11 is provided on one side of the motor 3, and both the motor 3 and the mounting plate 1 are fixedly connected to the support frame 11. The mounting plate 1 provides support force to the support frame 11, which supports the motor 3 and improves the stability of the motor 3.

[0024] In this embodiment, a filtration device for high-temperature resistant PET production and processing is used. The mounting plate 1 is fixed to the base with bolts. High-temperature resistant PET particles are placed inside the outer polygonal cylinder 8 and inside the inner filter barrel 4. The mounting plate 1 provides support to the support frame 11, which in turn supports the motor 3. The motor 3 drives the transmission shaft 2 to rotate. The transmission shaft 2 rotates inside the mounting plate 1, simultaneously causing the inner filter barrel 4 to rotate. The high-temperature resistant PET particles inside the inner filter barrel 4 are filtered over a large area through multiple inner bottom holes 5 and multiple inner side holes 6. Simultaneously, the inner filter barrel 4 drives the spacer cylinder 17 to rotate, which in turn drives multiple linkage bars 7 to rotate. The linkage bars 7 drive the outer polygonal cylinder 8 to rotate, causing the high-temperature resistant PET particles inside the outer polygonal cylinder 8 to rotate and separate, achieving large-area rotational filtration through multiple outer side holes 9 and outer bottom holes 10 inside the outer polygonal cylinder 8.

[0025] Example 2: In this embodiment, as Figure 3 - Figure 4As shown, a dispersion bar 12 is fixed to the outer wall of the drive shaft 2, below the mounting sleeve 1. Multiple linkage blocks 13 are fixedly connected to the lower surface of the dispersion bar 12, and the linkage blocks 13 are fixedly connected to the linkage bar 7. A movable bar 14 is fixedly connected to one end of each linkage bar 7, and a slider 15 is fixed to the top of the movable bar 14. A slide rail 16 is installed on the outer wall of the slider 15, and the slide rail 16 is fixedly connected to the mounting sleeve 1. The slide rail 16 guides the slider 15 to slide. The multiple linkage blocks 13 are arranged in a circumferential distribution, and the linkage blocks 13 are perpendicular to the linkage bar 7. The lower surface of the slider 15 has an arc-shaped cross-section, and the slide rail 16 also has an arc-shaped cross-section.

[0026] In this embodiment, the filter device used in the production and processing of high-temperature resistant PET is used such that when the drive shaft 2 rotates, it simultaneously drives the dispersing strip 12 to rotate. The dispersing strip 12 drives multiple linkage blocks 13 to rotate, which in turn drives the linkage strip 7 to rotate. At the same time, the linkage strip 7 drives the moving strip 14 to rotate, which in turn causes the slider 15 to rotate. Thus, the slider 15 rotates stably along the inner wall of the slide rail 16. Meanwhile, the mounting plate 1 supports the slide rail 16, ensuring that the drive shaft 2 can rotate stably during the filtration process, and ensuring that the inner filter barrel 4 can rotate stably during the filtration process.
