Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, specifically a high-temperature and high-pressure homogenizer for flash spinning. Background Technology

[0002] A homogenizer, also known simply as a grinding homogenizer, operates through the precise coordination of its rotor and stator. Homogenizers are used for the ultrafine particle grinding and homogenization of fillers in chemical raw materials, paints, and coatings. In flash spinning, polymers are typically dissolved in volatile solvents; the homogenizer uses high shear force to fully disperse the polymer chains, avoiding localized concentration inconsistencies and ensuring consistent rheological properties of the solution. Polymers or additives may agglomerate due to electrostatics or van der Waals forces; the homogenizer can physically break up these agglomerates, preventing spinneret clogging or fiber diameter fluctuations.

[0003] Most existing homogenizers use a motor to drive a rotating shaft, which in turn drives a stator and a rotor to rotate and homogenize. Most of them only have a single-stage shearing structure and a fixed speed, resulting in limited homogenization effect and low mixing efficiency. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a motor to drive the upper and lower gears to rotate, thereby achieving the opposite rotation of the drum and shaft. This, in turn, causes the rotor plate and stator plate one to rotate in opposite directions, enhancing the shearing force generated by rotor rod one and achieving initial crushing. The material enters the interior of stator plate two through the guide ring and guide plate. The shaft causes the main gear to drive the two side slave gears to rotate, which in turn causes the rotor frame to drive rotor rod two to rotate, achieving a multi-stage shearing effect. In addition, the different rotation speeds of rotor rod one and rotor rod two further improve the homogenization effect of the homogenizer.

[0013] 2. This utility model also provides a pressure balance hole on the stator plate to balance the axial pressure and radial pressure difference in the shearing chamber inside the homogenizing cylinder. This eliminates the high-pressure eddy current formed in the edge area due to centrifugal force when the rotor rotates at high speed. Balancing the pressure in the shearing chamber can prevent the formation of microbubbles in the material solution caused by the cavitation effect caused by local pressure changes.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a high-temperature and high-pressure homogenizer for flash spinning, comprising a shell 1, the inner wall of which is welded to a fixing plate 2, the fixing plate 2 being welded to the outer side of a homogenizing cylinder 3, the bottom of which is funnel-shaped, the bottom of which is welded to one end of a discharge pipe, and the bottom of which is welded to one end of a feed pipe 4. Control valves are installed in both the feed pipe 4 and the discharge pipe. A funnel-shaped material plate is installed inside the homogenizing cylinder 3, with one end of the feed pipe 4 positioned above the funnel-shaped material plate, ensuring that the solution material entering through the feed pipe 4 can pass through the funnel-shaped material plate into the space between the rotor plate 11 and the stator plate 13 at the center, and further enters the shearing chamber between the rotor rod 12 and the stator rod 14 for shearing and crushing.

[0021] The homogenizing cylinder 3 is rotatably connected to the outside of the rotating cylinder 5 via a bearing sleeve. The top of the rotating cylinder 5 extends above the homogenizing cylinder 3 and is welded and fixed to the lower gear 6. The inside of the rotating cylinder 5 is rotatably connected to the rotating shaft 7 via a bearing sleeve. The top of the rotating shaft 7 extends above the rotating cylinder 5 and is welded and fixed to the upper gear 8. The lower gear 6 and the upper gear 8 are located on the upper and lower sides of the drive gear 10, respectively. The lower gear 6, the upper gear 8, and the drive gear 10 are all bevel gears. The drive gear 10 meshes with both the lower gear 6 and the upper gear 8. The side of the housing 1 is connected and fixed to the motor 9 via bolts. The output end of the motor 9 is fixedly connected to the drive shaft via a coupling. One end of the drive shaft is connected to... The drive gear 10 is fixedly connected. Since the motor 9 is located outside the housing 1, the impact of high temperature and high pressure on the motor 9 is reduced, extending its service life. The motor 9 causes the drive gear 10 to drive the lower gear 6 and the upper gear 8 to rotate in opposite directions, further causing the rotor plate 11 and stator plate 13 to rotate in opposite directions, which in turn causes the rotor rod 12 and stator rod 14 to rotate in opposite directions. This enhances the shear force on the solution in the shear chamber between the rotor rod 12 and stator rod 14. The outer side of the rotor rod 12 is fixedly connected to several obtuse-angled trapezoidal tooth blocks. The obtuse-angled trapezoidal tooth blocks have a high impact force when rotating, thereby enhancing the gap shear force.

[0022] The outer side of the rotating cylinder 5 is welded and fixed to the rotor plate 11, and the bottom of the rotor plate 11 is welded and fixed to the rotor rod 12. The inner wall of the homogenizing cylinder 3 is welded and fixed to the guide ring 16. The edges of the top and bottom surfaces of the guide ring 16 extend inward at an inward angle. The guide ring 16 divides the interior of the homogenizing cylinder 3 into two large and connected shearing chambers. The inclined surface of the guide ring 16 facilitates the flow of the solution.

[0023] The outer side of the rotating shaft 7 is welded and fixed to the stator plate 13. The upper surface of the stator plate 13 is welded and fixed to the stator rod 14. Pressure balance holes 15 are formed on the surface of the stator plate 13. The pressure balance holes 15 are evenly distributed in a circumferential array at the edge of the stator plate 13. The pressure balance holes 15 can balance the axial pressure and radial pressure difference in the shear chamber of the homogenizing cylinder 3, thereby eliminating the high-pressure eddies formed in the edge area due to centrifugal force when the rotor rotates at high speed, and greatly reducing microbubbles in the solution.

[0024] The bottom end of the rotating shaft 7 extends below the guide ring 16 and is welded and fixed to the guide plate 17. The guide plate 17 is welded and fixed to the inner wall of the stator plate 22 via a mounting plate. The stator plate 22 is welded and fixed to the inner wall of the homogenizing cylinder 3 via a side plate. The connecting shaft 19 and the driven gear 20 are symmetrically distributed on both sides of the main gear 18. The main gear 18 is a large gear, and the driven gear 20 is a small gear. The driven gear 20 meshes with the main gear 18. The bottom end of the connecting shaft 19 is welded and fixed to the rotor frame 21. The rotor frame 21 is welded and fixed to the top of the rotor rod 2. Several triangular tooth blocks are fixedly connected to the outer side of the rotor rod 2. Turbulence is generated by the tips of the triangular tooth blocks during rotation, thereby improving the shearing effect of the solution.

[0025] Working principle: During operation, the material solution enters the homogenizing cylinder 3 through the feed pipe 4. It then flows through the guide funnel on the inner wall of the homogenizing cylinder 3 to the shearing chamber between rotor rod 12 and stator rod 14. The motor 9 drives the drive gear 10, which in turn drives the lower gear 6 and upper gear 8 to rotate. Since the lower gear 6 and upper gear 8 are located at the upper and lower ends of the drive gear 10, the rotating cylinder 5 and rotating shaft 7 rotate in opposite directions. This further causes the rotor rod 12 and stator rod 14 to rotate in opposite directions. Large particles or agglomerates in the solution are broken down by the trapezoidal teeth on the outer side of the rotor rod 12. The obtuse-angled trapezoidal teeth have a high impact force during rotation, thus enhancing the interstitial shearing force. To improve crushing efficiency, the solution then flows under the guidance of the guide ring 16 and the guide plate 17 to the shearing gap between the rotor rod 2 and the stator rod 2 below the rotor frame 21. The main gear 18 rotates through the rotating shaft 7, which drives the connecting shaft 19 and the driven gear 20 on both sides to rotate, thereby causing the rotor rod 2 to rotate for shearing. Several triangular tooth blocks are set on the outer side of the rotor rod 2. The high-frequency shearing area is formed by the tips of the triangular tooth blocks, thereby improving the dispersion efficiency. Then the solution is squeezed out from the conical micro-holes on the outer side of the stator plate 22 to further enhance the shearing and dispersion effect. Finally, the solution inside the homogenizing cylinder 3 is discharged from the discharge pipe at the bottom of the shell 1.
