Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically to a melt filtration device for processing recycled polyester fibers. Background Technology

[0002] Recycled polyester fiber is a polyester fiber made by recycling waste plastic products (such as PET bottles, waste textiles, etc.). With environmental protection as its core, it transforms plastic waste that might otherwise end up in landfills or pollute the environment into reusable textile materials. It is an important material in sustainable fashion and the circular economy. After recycling, polyester fiber needs to be heated to a molten state, but unmelted particles will still exist in the molten state. These particles will affect the production and processing quality of recycled polyester fiber. Traditional filtration methods mostly use a single set of filter screens to filter out these unmelted particles. After long-term use, these screens will become clogged. When they need to be replaced, the machine needs to be shut down, which will delay production time. In order to improve this situation, a melt filtration device for recycled polyester fiber processing is proposed.

[0003] The filter device for polyester fiber processing disclosed in the authorization announcement number CN111893586B includes an upper guide tube, a lower guide tube, and a filter screen. The upper and lower guide tubes are both fixedly mounted on a screen changing box and are connected. The filter screen is placed inside the screen changing box. The screen changing box at the position where the upper and lower guide tubes are connected is provided with an arc-shaped sealing surface. A rotating shaft is rotatably mounted inside the screen changing box. Four supports are evenly and uniformly distributed on the rotating shaft. The outer support plate and the inner support plate of the supports are fixedly connected by a frame rod. The rotational contour surface of the outer support plate matches the outer contour of the arc-shaped sealing surface. A support block is provided at the position where the arc-shaped sealing surface is at the same horizontal line as the rotating shaft. One end of the rotating shaft passes through the screen changing box and is fixedly connected to a power component. A screen feeding device is fixedly mounted on the screen changing box wall plate corresponding to the other end of the rotating shaft.

[0004] While it has solved the technical problem of low efficiency due to the limited number of filter screens that can be replaced in traditional devices, it has not solved the problem that existing filtration devices are not convenient to use for easy linkage adjustment of different filter cartridges to filter plastic liquids, and are not easy to quickly disassemble and replace filter cartridges, thus affecting the filtration effect and the convenience of disassembling and replacing filter cartridges. Utility Model Content

[0005] The purpose of this invention is to provide a melt filtration device for processing recycled polyester fibers, in order to solve the problems mentioned in the background art, such as the inconvenience of convenient linkage adjustment of filtration devices to filter plastic liquid using different filter cartridges, the difficulty in quickly disassembling and replacing filter cartridges, and the impact on filtration effect and the convenience of disassembling and replacing filter cartridges.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a melt filter device for processing recycled polyester fibers, comprising a collection box and a filter frame. The filter frame is installed at the top of the collection box, and a melting furnace is installed at the top of the filter frame. Four sets of hydraulic cylinders are installed at equal intervals on the outer wall of the collection box. Each hydraulic cylinder has a push arm installed at its output end, and the push arm is connected to the filter frame. A placement plate is installed at the bottom of the filter frame. An X-axis frame is installed inside the filter frame, and an X-screw is movably installed inside the X-axis frame.

[0007] Preferably, the surface of the X-lead screw is fitted with an X-thread sleeve, and the X-thread sleeve is threadedly connected to the X-lead screw.

[0008] Preferably, an X-axis motor is mounted on the side wall of the X-axis frame, and the output end of the X-axis motor is connected to the X-lead screw.

[0009] Preferably, a Y-axis frame is installed at the bottom end of the X-threaded sleeve, and a Y-lead screw is movably installed inside the Y-axis frame.

[0010] Preferably, a Y-axis motor is installed on the side wall of the Y-axis frame, and the output end of the Y-axis motor is connected to the Y-lead screw.

[0011] Preferably, the surface of the Y-lead screw is fitted with a Y-threaded sleeve, and the Y-threaded sleeve is threadedly connected to the Y-lead screw.

[0012] Preferably, a discharge pipe is installed on the side wall of the Y-threaded sleeve, and the discharge pipe is connected to the melting furnace through a high-temperature resistant flexible hose.

[0013] Preferably, the top of the placement plate is equipped with multiple sets of feed pipes at equal intervals, and the feed pipes are fixedly connected to the placement plate.

[0014] Preferably, each feed pipe is equipped with a filter cylinder inside, and a sealing ring is installed at the port of each filter cylinder.

[0015] Preferably, four sets of L-shaped grooves with equal spacing are installed on the inner wall of the feed pipe, and four sets of limiting blocks with equal spacing are installed on the outer wall of the filter cylinder, and the limiting blocks are slidably connected to the L-shaped grooves.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the filtration device not only realizes the convenient linkage adjustment of using different filter cartridges to filter plastic liquid, and facilitates quick disassembly and replacement of filter cartridges, but also improves the filtration effect and the convenience of disassembly and replacement of filter cartridges.

[0017] Recycled waste plastic products are placed in a melting furnace, where they are heated into molten plastic. However, unmelted particles remain. The molten plastic flows through a high-temperature flexible hose into the discharge pipe and then into the inlet pipe. The molten plastic then enters the filter cartridge through the inlet pipe and seeps out through the pores on the surface of the cartridge. Unmelted particles remain inside the filter cartridge. When a set of filter cartridges reaches the end of its service life, the X-axis motor drives the X-screw to rotate. The X-screw, through the X-threaded sleeve, moves the Y-axis frame. The Y-axis motor drives the Y-screw to rotate, which, through the Y-threaded sleeve, moves the discharge pipe. This adjusts the output position of the discharge pipe, allowing it to move to the top of different inlet pipes to feed molten plastic into them for filtration. This prevents clogging caused by prolonged use of a single set of filter cartridges. The blockage affects the filtration effect. The collection box and filter frame are also designed with a high-temperature environment to prevent the plastic liquid from condensing. Convenient linkage adjustment is achieved to use different filter cartridges to filter the plastic liquid, which improves the filtration effect. The hydraulic cylinder drives the push arm to move upward, which in turn drives the filter frame and melting furnace to move upward. The filter frame drives the placement plate, feed pipe and filter cartridge to move upward, so that the filter cartridge moves to the outside of the collection box. Then the filter cartridge is rotated, which drives the limit block to rotate. The sealing ring ensures the sealing connection between the filter cartridge and the feed pipe. When the limit block rotates to the turning position of the L-shaped groove, the filter cartridge is pulled down to remove it from the feed pipe. Then, the filter cartridge is replaced by repeating the above operation in reverse. This achieves convenient disassembly and replacement of the filter cartridge and improves the convenience of disassembly and replacement of the filter cartridge. Attached Figure Description

[0027] Example 1

[0028] Please see Figure 1-5The present invention provides an embodiment of a melt filtration device for processing recycled polyester fibers, comprising a collection box 1 and a filter frame 2. The filter frame 2 is installed at the top of the collection box 1, and a melting furnace 3 is installed at the top of the filter frame 2. Four sets of hydraulic cylinders 4 are installed at equal intervals on the outer wall of the collection box 1. The hydraulic cylinders 4 serve as power drives. Push arms 5 are installed at the output ends of the hydraulic cylinders 4, and the push arms 5 are connected to the filter frame 2. A placement plate 7 is installed at the bottom end of the filter frame 2. An X-axis frame 6 is installed inside the filter frame 2. An X-screw 8 is movably installed inside the X-axis frame 6. An X-thread sleeve 9 is fitted on the surface of the X-screw 8, and the X-thread sleeve 9 is threadedly connected to the X-screw 8. An X-axis motor 10 is installed on the side wall of the X-axis frame 6. The X-axis motor 10 serves as power drives, and the output end of the X-axis motor 10 is connected to the X-screw 8.

[0029] The recycled waste plastic products are placed in the melting furnace 3, where they are heated into molten plastic liquid. However, unmelted particles are still present. The molten plastic liquid enters the discharge pipe 15 through a high-temperature resistant flexible hose and is discharged into the inlet pipe 17. The molten plastic liquid then enters the filter cylinder 16 through the inlet pipe 17 and seeps out through the holes on the surface of the filter cylinder 16. Unmelted particles remain inside the filter cylinder 16. When a set of filter cylinders 16 reaches the end of its service life, the X-axis motor 10 is turned on, which drives the X-screw 8 to rotate. With the X-screw 8 connected to the X-threaded sleeve 9, the X-screw 8 drives the Y-axis frame 11 to move through the X-threaded sleeve 9. When the Y-axis motor 12 is turned on, the Y-axis motor 12 drives the Y-screw 13 to rotate. With the Y-screw 13 and the Y-threaded sleeve 14 connected by threads, the Y-screw 13 drives the discharge pipe 15 to move through the Y-threaded sleeve 14, thereby moving and adjusting the output position of the discharge pipe 15 so that the discharge pipe 15 moves to the top of different feed pipes 17 to input plastic liquid into different feed pipes 17 for filtration. This avoids the problem of internal blockage caused by prolonged use of a single set of filter cartridges 16, which affects its filtration effect. The inside of the collection box 1 and the filter frame 2 is also a high-temperature environment to prevent the plastic liquid from condensing. This realizes convenient linkage adjustment to use different filter cartridges to filter plastic liquid, improving the filtration effect.

[0030] The bottom end of the X-thread sleeve 9 is equipped with a Y-axis frame 11, and the Y-axis screw 13 is movably installed inside the Y-axis frame 11.

[0031] A Y-axis motor 12 is installed on the side wall of the Y-axis frame 11. The Y-axis motor 12 plays the role of power drive, and the output end of the Y-axis motor 12 is connected to the Y lead screw 13. A Y threaded sleeve 14 is fitted on the surface of the Y lead screw 13, and the Y threaded sleeve 14 is threadedly connected to the Y lead screw 13.

[0032] A discharge pipe 15 is installed on the side wall of the Y-threaded sleeve 14, and the discharge pipe 15 is connected to the melting furnace 3 through a high-temperature resistant flexible hose.

[0033] The top of the placement plate 7 is equipped with multiple sets of feed pipes 17 at equal intervals, and the feed pipes 17 are fixedly connected to the placement plate 7. Each feed pipe 17 is equipped with a filter cylinder 16, and a sealing ring 19 is installed at the port of each filter cylinder 16.

[0034] The inner wall of the feed pipe 17 is equipped with four sets of L-shaped grooves 20 at equal intervals, and the outer wall of the filter cylinder 16 is equipped with four sets of limiting blocks 18 at equal intervals, and the limiting blocks 18 are slidably connected to the L-shaped grooves 20.

[0035] When the filter cartridge 16 needs to be replaced, the hydraulic cylinder 4 is opened, which drives the push arm 5 to move upward. The push arm 5 then drives the filter frame 2 and the melting furnace 3 to move upward. The filter frame 2 then drives the placement plate 7, the feed pipe 17, and the filter cartridge 16 to move upward, so that the filter cartridge 16 is moved to the outside of the collection box 1. Then, the filter cartridge 16 is rotated, which drives the limiting block 18 to rotate. The sealing ring 19 ensures the sealed connection between the filter cartridge 16 and the feed pipe 17. When the limiting block 18 rotates to the turning position of the L-shaped groove 20, the filter cartridge 16 is pulled down to remove it from the feed pipe 17. After that, a new filter cartridge 16 is replaced, and the above operation is repeated in reverse to complete the replacement of the filter cartridge 16. This achieves convenient disassembly and replacement of the filter cartridge and improves the convenience of disassembly and replacement of the filter cartridge.

[0036] Work steps

[0037] Recycled waste plastic products are placed in a melting furnace 3, where they are heated into molten plastic liquid. However, unmelted particles are still present. The molten plastic liquid enters the discharge pipe 15 through a high-temperature resistant flexible hose and is discharged into the inlet pipe 17. The molten plastic liquid then enters the filter cartridge 16 through the inlet pipe 17 and seeps out through the holes on the surface of the filter cartridge 16. Unmelted particles remain inside the filter cartridge 16. When a set of filter cartridges 16 reaches the end of its service life, the X-axis motor 10 drives the X-screw 8 to rotate. The X-screw 8 drives the Y-axis frame 11 to move through the X-thread sleeve 9. The Y-axis motor 12 drives the Y-screw 13 to rotate. The Y-screw 13 drives the discharge pipe 15 to move through the Y-thread sleeve 14, thereby adjusting the output position of the discharge pipe 15 so that it moves to the top of different inlet pipes 17 to feed molten plastic liquid into different inlet pipes 17 for filtration, thus avoiding prolonged use. A single filter cartridge 16 can become clogged, affecting its filtration efficiency. The collection box 1 and filter frame 2 are kept in a high-temperature environment to prevent the molten plastic from solidifying. When the filter cartridge 16 needs replacement, the hydraulic cylinder 4 drives the push arm 5 upwards, which in turn moves the filter frame 2 and melting furnace 3 upwards. The filter frame 2 then moves the placement plate 7, feed pipe 17, and filter cartridge 16 upwards, moving the filter cartridge 16 to the outside of the collection box 1. The filter cartridge 16 is then rotated, causing the limiting block 18 to rotate. The sealing ring 19 ensures a sealed connection between the filter cartridge 16 and the feed pipe 17. When the limiting block 18 rotates to the turning position of the L-shaped groove 20, the filter cartridge 16 is pulled downwards to remove it from the feed pipe 17. A new filter cartridge 16 is then replaced, and the above operation is repeated to complete the replacement. This concludes the usage instructions for the melt filtration device for recycled polyester fiber processing.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
