[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a detachable filter for an extruder. A feed box 2 is fixedly connected to the top of the extruder body 1, which feeds raw materials into the extruder body 1 for extrusion processing. An extrusion device 3 is fixedly connected to the top of the extruder body 1, which performs high-temperature and high-pressure treatment on the material, extruding it from the extruder. A fixing block 5 is fixedly connected to the top of the extrusion device 3, which fixes and supports other components to ensure the stability of the entire system. A feed hopper 4 is fixedly connected to the top of the fixing block 5, which guides and distributes the raw materials, ensuring uniform entry of the raw materials into the extruder body 1. A filter box 6 is slidably connected inside the fixing block 5, which filters impurities in the material to ensure the purity of the material during extrusion processing. A quick-release assembly is provided inside the filter box 6, allowing for easy disassembly and cleaning, reducing maintenance time and costs.

[0034] The quick-release assembly includes a hollow column 7, which is slidably connected inside the filter box 6. The hollow column 7 provides support and guidance, allowing the filter assembly to move smoothly during disassembly. A fixing rod 8 is slidably connected inside the hollow column 7, controlling the disassembly action of the filter. A pressure roller 9 is fixedly connected to one end of the fixing rod 8, which engages with a retaining ball 12 to ensure rapid unlocking of the filter during disassembly, improving disassembly efficiency. A reset assembly is located on the outer wall of the fixing rod 8. After the filter is disassembled, the reset assembly helps the fixing rod 8 and pressure roller 9 return to their original positions, preparing for the next use. A retaining ball 12 is slidably connected to the inner wall of the fixing block 5 when the filter is in operation, securing the filter box 6. During disassembly, the pressure roller 9... The function of the retaining ball 12 is to allow it to quickly detach from the fixing block 5, thus enabling the filter to be disassembled. The inner wall of the filter box 6 is provided with a limiting component, which includes a limiting ring 11 and a spring 10. The limiting ring 11 is fixedly connected to the outer wall of the fixing rod 8 and slidably connected to the inner wall of the hollow column 7. The function of the limiting ring 11 is to limit the movement range of the fixing rod 8, ensuring that the fixing rod 8 will not exceed the predetermined position when it moves inside the hollow column 7, thereby ensuring the stability and safety of the overall device. The outer wall of the fixing rod 8 is fitted with a spring 10. One end of the spring 10 is fixedly connected to the side wall of the limiting ring 11, and the other end of the spring 10 is fixedly connected to the inside of the hollow column 7. The function of the spring 10 is to provide a restoring force, so that the limiting ring 11 can return to its original position after being subjected to external force, thus playing a role in buffering and resetting.

[0035] Specifically, when installing the filter box 6, first place the filter box 6 inside the fixing block 5. By gently pressing the pressure roller 9, the fixing rod 8 can slide smoothly inside the hollow column 7. As the fixing rod 8 slides, the retaining ball 12 also retracts and enters the hollow column 7. At this time, the hollow column 7 can be smoothly inserted between the filter box 6 and the fixing block 5, ensuring a firm connection between the two. After releasing the pressure roller 9, the spring 10 will quickly rebound, and the limiting ring 11 will play its role, securely limiting the spring 10 to ensure that it is not overstretched. When the system resets, the fixing rod 8 will continue to apply pressure to the retaining ball 12, so that the retaining ball 12 precisely engages with the groove inside the fixing block 5, achieving a firm fixation effect. When disassembling, simply press the pressure roller 9 again, and the retaining ball 12 will quickly retract back to the inner wall of the hollow column 7 as the fixing rod 8 slides, thus easily achieving quick disassembly of the filter box 6. The whole process is simple and efficient, ensuring that the installation and disassembly of the filter box 6 are both convenient and safe, reducing the difficulty and time cost of manual operation.

[0036] Reference Figures 4-5The limiting component includes a hollow block 15, which is fixedly connected to the inner wall of the filter box 6. The hollow block 15 serves as part of the limiting structure, providing stable support and positioning to ensure that the sliding column 16 and the locking block 19 can operate smoothly within a predetermined position. The sliding column 16 is slidably connected inside the hollow block 15. One end of the sliding column 16 is fixedly connected to a limiting block 17, and the other end is fixedly connected to a locking block 19. The sliding column 16 supports the limiting block 17 and the locking block 19, allowing them to slide freely along the axial direction inside the hollow block 15. The limiting block 17 restricts the movement range of the sliding column 16, preventing excessive movement. The locking block 19 is slidably connected to the inner wall of the hollow block 15. The locking block 19 cooperates with other components within the filter box 6, using sliding connections to achieve component positioning and restriction, ensuring the normal operation of the device. A second spring 18 is sleeved on the outer wall of the sliding column 16, with one end of the second spring 18 fixedly connected to the hollow block 15. The inner wall of the filter box 6 has a spring 18 fixedly connected to the side wall of the block 19 at one end. The function of the spring 18 is to provide additional pressure to ensure that the block 19 can always fit tightly against the inner wall of the hollow block 15, thereby enhancing the stability and working efficiency of the block 19 and preventing loosening. The filter box 6 is equipped with a filter screen 14. The function of the filter screen 14 is to filter the substances entering the box, ensuring that only filtered liquids or gases can pass through, thereby improving filtration efficiency and cleanliness. The upper surface of the filter box 6 is equipped with a sealing strip 13. The function of the sealing strip 13 is to seal the upper surface of the filter box 6 to prevent material leakage, improve the overall sealing performance, and ensure that no leakage occurs during the filtration process. The inner wall of the filter box 6 is fixedly connected to a fixing frame 20. The top of the fixing frame 20 fits against the bottom of the block 19. The function of the fixing frame 20 is to provide support and fixation for other components inside the filter box 6, ensuring the stable connection between the block 19 and the fixing frame 20, and ensuring the structural integrity and reliability of the overall device.

[0037] Specifically, when replacing the filter screen 14, first, by pulling the limiting block 17, the sliding column 16 drives the locking block 19 to slide smoothly inside the hollow block 15, carefully placing the filter screen 14 at the top of the fixed frame 20 to ensure a stable and reliable connection between the filter screen 14 and the frame. Then, the limiting block 17 is released, at which point the spring 18 will drive the locking block 19 to automatically reset through elastic force. The locking block 19 firmly fixes the filter screen 14 to the surface of the fixed frame 20, ensuring that the filter screen 14 will not be displaced due to the pressure of the material flow. This effectively avoids the problem of the filter screen 14 shifting due to external pressure during use, thus affecting the filtration effect. This design effectively improves the stability and reliability of the equipment in actual use, while making the replacement of the filter screen 14 more convenient and efficient, minimizing the risk of equipment failure, ensuring a stable filtration effect of the fluid during production, and further improving the performance and service life of the equipment.

[0038] Working principle: When installing the filter box 6, place the filter box 6 inside the fixing block 5. By pressing the pressure roller 9, the fixing rod 8 slides inside the hollow column 7. The retaining ball 12 retracts into the hollow column 7 as the fixing rod 8 slides. Insert the hollow column 7 into the filter box 6 and the fixing block 5. Release the pressure roller 9, and the spring 10 returns. The limiting ring 11 limits the spring 10. During reset, the fixing rod 8 squeezes the retaining ball 12, engaging the retaining ball 12 with the groove inside the fixing block 5. When removing, press the pressure roller 9, and the retaining ball 12 retracts into the inner wall of the hollow column 7 as the fixing rod 8 slides. This achieves the effect of quickly installing and removing the filter box 6.

[0039] When replacing the filter screen 14, by pulling the limiting block 17, the sliding column 16 drives the locking block 19 to slide inside the hollow block 15, placing the filter screen 14 on top of the fixed frame 20. Releasing the limiting block 17, the spring 18 drives the locking block 19 to reset, and the locking block 19 engages the filter screen 14 on the surface of the fixed frame 20. This achieves the effect of conveniently replacing the filter screen 14 and limiting the position of the filter screen 14, preventing the filter screen 14 from shifting due to pressure from material flow during use, thus improving the stability of the equipment.
