[0002] A recycled polyester melt filter is a device used to process recycled polyester (such as polyethylene terephthalate, PET) solutions. This device is mainly used to remove impurities, particles, and other contaminants in the solution to ensure the smooth progress of subsequent processing.

[0003] After the melt filter in the prior art is used for a period of time, the filter screen in the filter will be blocked by excessive accumulated impurities, resulting in a significant reduction in the subsequent polyester melt filtration efficiency. Moreover, due to the high integrity of the filter, it is difficult to disassemble, clean, or replace the filter screen, thereby increasing the cleaning difficulty of the device and further reducing the service life of the filter. Summary of the Utility Model

[0004] In view of the above problems existing in the prior art, the present application provides a recycled polyester melt filtering device to solve the technical problems of the prior art.

[0005] To achieve the above object, in a first aspect, the present application provides a recycled polyester melt filtering device, including a tank body. One side of the top of the tank body is fixedly connected with a feed port. A filter rack is fixedly connected inside the tank body. A first filter screen is arranged inside the filter rack. A cleaning brush is provided on the top of the first filter screen. Hammering columns are slidably connected to both sides inside the tank body. A through groove is opened inside the filter rack and outside the first filter screen. A collection box is provided below the through groove. A transmission assembly is arranged on the top of the tank body.

[0006] As an implementation manner of the present utility model, the transmission assembly includes a motor and a linkage unit. The motor is fixedly connected to the top of the tank body through a limiting plate. The output end of the motor is fixedly connected with a rotating shaft. The bottom of the rotating shaft extends into the tank body and is fixedly connected with the cleaning brush. The rotating shaft is rotatably connected to the inner wall of the tank body. The hammering columns can perform reciprocating motion through the linkage unit.

[0007] As an implementation manner of the present utility model, the linkage unit includes a rotating column. The rotating column is fixedly connected to the outside of the output end of the motor. An arc-shaped groove is opened on the outside of the rotating column. Limiting frames are fixedly connected to both sides of the top of the tank body. Slide rods are slidably connected inside both limiting frames. One ends of the two slide rods are respectively slidably connected to both sides of the arc-shaped groove. The tops of the two hammering columns extend outside the tank body and are respectively fixedly connected to the corresponding slide rods.

[0008] As an implementation manner of the present utility model, an installation frame is fixedly connected inside the tank body and below the filter rack. The collection box is threadedly connected to the installation frame, and a second filter screen is arranged at the bottom of the collection box.

[0009] As an implementation manner of the present utility model, a base is hinged to the bottom of the tank body through a hinge, and sealing gaskets are fixedly connected to the top of the base and the bottom of the tank body respectively.

[0010] As an implementation manner of the present utility model, a discharge port is fixedly connected to the bottom of the base, and an electromagnetic valve is installed outside the discharge port.

[0011] As an implementation manner of the present utility model, mounting blocks are fixedly connected to one side of the bottom of the tank body and one side of the top of the base respectively, and bolts are threadedly connected inside the two mounting blocks.

[0012] As an implementation manner of the present utility model, support legs are fixedly connected to the bottom of the base at equal intervals, and both the motor and the electromagnetic valve are electrically connected to an external controller.

[0013] Different from the prior art, the technical solution of the present application can clean the impurities isolated on the top of the first filter screen through a rotating cleaning brush during the process of filtering the melt, so that the impurities fall into the interior of the collection box for easy cleaning, effectively avoiding the problem that the filtering effect is affected due to excessive isolated impurities after the first filter screen is used for a long time. At the same time, the reciprocating hammering columns on both sides can drive the filter rack to vibrate at a high frequency, so that the large-particle impurities on the top of the first filter screen continuously vibrate. This not only drives the impurities to quickly fall into the interior of the collection box, but also avoids the consequence that the large-particle impurities enter the interior of the first filter screen and cause blockage and difficult cleaning, thereby further improving the filtering effect.

For those skilled in the art to which the present application pertains, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0033] According to some embodiments of the present application, refer to Figures 1-5 , a regenerated polyester melt filtration device, comprising a tank body 1, a feed inlet 2 is fixedly connected to one side of the top of the tank body 1, a filter rack 3 is fixedly connected inside the tank body 1, a first filter screen 4 is arranged inside the filter rack 3, a cleaning brush 6 is provided at the top of the first filter screen 4, hammering columns 7 are slidably connected to both sides inside the tank body 1, a through groove 8 is formed inside the filter rack 3 and outside the first filter screen 4, a collection box 9 is arranged below the through groove 8, and a transmission assembly is arranged at the top of the tank body 1.

[0034] Specifically, the transmission assembly includes a motor 10 and a linkage unit. The motor 10 is fixedly connected to the top of the tank body 1 through a limit plate. The output end of the motor 10 is fixedly connected to a rotating shaft 5. The bottom of the rotating shaft 5 extends into the tank body 1 and is fixedly connected to the cleaning brush 6. The rotating shaft 5 is rotatably connected to the inner wall of the tank body 1. The hammering columns 7 can reciprocate through the linkage unit. The linkage unit includes a rotating column 11. The rotating column 11 is fixedly connected to the outside of the output end of the motor 10. An arc-shaped groove is formed on the outside of the rotating column 11. Limit frames 12 are fixedly connected to both sides of the top of the tank body 1. Slide rods 13 are slidably connected inside the two limit frames 12. One ends of the two slide rods 13 are respectively slidably connected to both sides of the arc-shaped groove. The tops of the two hammering columns 7 extend outside the tank body 1 and are respectively fixedly connected to the corresponding slide rods 13.

[0035] Through the above technical solution, feeding can be carried out through the feed inlet 2, and then impurities in the melt can be filtered through the first filter screen 4 inside the filter rack 3. The motor 10 is started by an external controller, and the output end of the motor 10 drives the rotating column 11 and the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the cleaning brush 6 at the bottom to clean the impurities on the top of the first filter screen 4, making the impurities separate from the first filter screen 4 and then fall into the interior of the collection box 9 through the through groove 8, and are isolated by the second filter screen 15 in the collection box 9. The melt following the impurities can pass through the second filter screen 15 and drip downward, so that the collection of impurities can be completed through the collection box 9. The filtered melt can be discharged through the discharge port 17 after the solenoid valve 18 is opened. At the same time, while the rotating column 11 rotates, the slide rods 13 on both sides can be driven to reciprocate in the corresponding limit frames 12 through the external arc-shaped grooves, and the slide rods 13 drive the corresponding hammering columns 7 to reciprocate, so as to realize the staggered reciprocating undulating motion of the two hammering columns 7. Then, the filter rack 3 is subjected to high-frequency knocking through the hammering columns 7, making the first filter screen 4 vibrate, causing the large-particle impurities on the top of the first filter screen 4 to continuously vibrate, which can effectively prevent the large-particle impurities from being difficult to clean after entering the interior of the first filter screen 4 and causing blockage, thereby affecting the filtering effect of the first filter screen 4. During the filtering process of the melt, the cleaning brush 6 that rotates can clean the impurities isolated on the top of the first filter screen 4, making the impurities fall into the interior of the collection box 9 for easy cleaning, effectively avoiding the problem that the filtering effect is affected due to excessive isolated impurities after the first filter screen 4 is used for a long time. At the same time, the hammering columns 7 that reciprocate undulating on both sides can drive the filter rack 3 to vibrate at high frequency, resulting in continuous vibration of the large-particle impurities on the top of the first filter screen 4. This not only drives the impurities to quickly fall into the interior of the collection box 9, but also avoids the consequence that large-particle impurities enter the interior of the first filter screen 4 and cause blockage and difficulty in cleaning, thereby further improving the filtering effect.

[0036] Specifically, an installation rack 14 is fixedly connected inside the tank body 1 and below the filter rack 3. The collection box 9 is threadedly connected to the installation rack 14. A second filter screen 15 is arranged at the bottom of the collection box 9. The bottom of the tank body 1 is hinged to a base 16 through a hinge. Sealing gaskets are fixedly connected to the top of the base 16 and the bottom of the tank body 1. The bottom of the base 16 is fixedly connected to a discharge port 17. A solenoid valve 18 is installed outside the discharge port 17. Installation blocks 19 are fixedly connected to one side of the bottom of the tank body 1 and one side of the top of the base 16. Bolts 20 are threadedly connected inside the two installation blocks 19.

[0037] Through the above technical solution, when it is necessary to centrally clean the impurities inside the collection box 9, the bolts 20 are unscrewed, and the tank body 1 is opened. Then, the collection box 9 is screwed out from the interior of the installation rack 14 through the threaded connection relationship, and the impurities can be cleaned. The sealing gaskets provided can improve the sealing performance between the tank body 1 and the base 16.

[0038] Specifically, support legs are fixedly connected to the bottom of the base 16 at equal intervals, and both the motor 10 and the solenoid valve 18 are electrically connected to an external controller.

[0039] Through the above technical solution, the external controller facilitates the staff to quickly control the motor 10 and the solenoid valve 18.

[0040] During use, feeding can be carried out through the feeding port 2. Then, the impurities in the melt can be filtered by the first filter screen 4 inside the filter rack 3. The external controller is used to start the motor 10. The output end of the motor 10 drives the rotating column 11 and the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the cleaning brush 6 at the bottom to clean the impurities on the top of the first filter screen 4, causing the impurities to separate from the first filter screen 4 and then fall into the interior of the collection box 9 through the through groove 8, and being isolated by the second filter screen 15 in the collection box 9. The melt following the impurities can pass through the second filter screen 15 and drip downward. Thus, the collection of impurities can be completed through the collection box 9. The filtered melt can be discharged through the discharge port 17 after the solenoid valve 18 is opened. Meanwhile, while the rotating column 11 is rotating, the external arc-shaped groove drives the sliding rods 13 on both sides to reciprocate in the corresponding limiting frames 12, and the sliding rods 13 drive the corresponding hammering columns 7 to reciprocate, so as to realize the staggered reciprocating undulating movement of the two hammering columns 7. Then, the filter rack 3 is subjected to high-frequency knocking by the hammering columns 7, causing the first filter screen 4 to vibrate, resulting in continuous vibration of the large-particle impurities on the top of the first filter screen 4. This can effectively prevent large-particle impurities from being difficult to clean after entering the interior of the first filter screen 4 and causing blockage, thereby affecting the filtering effect of the first filter screen 4. In this device, during the filtration of the melt, the cleaning brush 6 rotates to clean the impurities isolated on the top of the first filter screen 4, causing the impurities to fall into the interior of the collection box 9 for easy cleaning, effectively avoiding the problem that the filtering effect is affected due to excessive isolated impurities after the first filter screen 4 is used for a long time. At the same time, the reciprocating undulating hammering columns 7 on both sides can drive the filter rack 3 to vibrate at high frequency, resulting in continuous vibration of the large-particle impurities on the top of the first filter screen 4. This not only drives the impurities to quickly fall into the interior of the collection box 9, but also avoids the consequence that large-particle impurities enter the interior of the first filter screen 4 and cause blockage and difficulty in cleaning, thereby further improving the filtering effect. When it is necessary to centrally clean the impurities inside the collection box 9, unscrew the bolt 20, open the tank body 1, and then screw out the collection box 9 from the interior of the mounting rack 14 through the threaded connection relationship, and then the impurities can be cleaned. The sealing gasket provided can improve the sealing performance between the tank body 1 and the base 16. The external controller facilitates the staff to quickly control the motor 10 and the solenoid valve 18.
