[0002] The slurry conveying device used in PTA production is a specialized device for conveying slurry in the PTA production process. It mainly consists of conveying pipelines, power components, etc. Its core function is to transport the slurry generated during the production process from one process or equipment to another process or equipment, so as to realize the material transfer between various production links, ensure that PTA production can be carried out continuously and stably, and meet the basic needs of slurry conveying at different locations and different process stages in the production process.

[0003] Existing technologies often struggle to balance ease of operation and sealing reliability when adjusting conveying distance. Either the connection seals fail during adjustment, leading to slurry leakage and affecting the production environment and raw material utilization, or the structure is not stable enough after adjustment, making it difficult to maintain the adjusted distance for a long time and adapt to different production layouts or process requirements. This results in poor adaptability of the equipment when facing diverse conveying scenarios.

[0004] Therefore, a slurry conveying device for PTA production is proposed to address the above problems. Utility Model Content

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figure 1 - Figure 4This utility model provides a slurry conveying device for PTA production, including a conveying pipe 1 and a conveying pipe 2. One end of the conveying pipe 1 is fixedly connected to a hose 5, and the other end of the hose 5 is fixedly connected to the conveying pipe 2. A fixing ring 3 is fixedly connected to the outer wall of the conveying pipe 1, and a fixing ring 4 is fixedly connected to the outer wall of the conveying pipe 2. A bearing 12 is provided inside the fixing ring 4, and a threaded rod 6 is fixedly connected to the inner wall of the bearing 12. The outer wall of the threaded rod 6 is threadedly connected to the inside of the fixing ring 3. A guide rod 7 is fixedly connected to the inside of the fixing ring 4, and the outer wall of the guide rod 7 is slidably connected to the inside of the fixing ring 3. A bevel gear 8 is fixedly connected to the end of the threaded rod 6. A rotating assembly is provided on the outer wall of the conveying pipe 2. The rotating assembly includes a U-shaped block 9, the lower surface of which is fixedly connected to the outer wall of the conveying pipe 2. A rotating column 10 is rotatably connected inside the U-shaped block 9, and a bevel gear 11 is fixedly connected to the bottom end of the rotating column 10. The tooth end of 11 meshes with the tooth end of bevel gear 8. Specifically, conveying pipe 1 and conveying pipe 2 are connected by hose 5 to form a conveying channel. Fixed ring 3 and fixed ring 4 are fixed on the outer walls of conveying pipe 1 and conveying pipe 2, respectively. The bearing 12 inside fixed ring 4 is used to support the rotation of threaded rod 6. Threaded rod 6 is threadedly connected to fixed ring 3. At the same time, guide rod 7 on fixed ring 4 passes into fixed ring 3 to form a sliding fit, restricting fixed ring 3 to rotate synchronously with threaded rod 6. U-shaped block 9 in the rotating assembly is fixed on conveying pipe 2 and supports the rotation of rotating column 10. Bevel gear 11 at the bottom of rotating column 10 meshes with bevel gear 8 at the end of threaded rod 6 to form a transmission. When rotating column 10 is rotated, threaded rod 6 is driven to rotate through bevel gear transmission. Under the action of thread and the limitation of guide rod 7, fixed ring 3 moves axially along threaded rod 6, causing conveying pipe 1 and conveying pipe 2 to expand and contract relative to each other and hose 5 to adjust the conveying distance.

[0021] Furthermore, such as Figure 1 As shown, a conveying pump 14 is provided at the other end of the conveying pipe 1, and a support base 13 is fixedly connected to the outer wall of the conveying pipe 1. Specifically, the conveying pump 14 at the other end of the conveying pipe 1 provides power for slurry conveying. Its operation can push the slurry to enter the conveying pipe 1 stably, ensuring the continuous flow of the slurry in the entire conveying channel. The support base 13 is used to support and fix the pipe, stabilizing the position of the conveying pipe 1. After adjusting the conveying distance, the support base 13 can fix the position of the conveying pipe 1 through a stable connection with the installation foundation, preventing it from shifting due to external forces during subsequent slurry conveying and keeping the adjusted conveying distance unchanged.

[0022] Furthermore, such as Figure 4 and Figure 5As shown, a cooling water tank 15 is fixedly connected to the outer wall of the second conveying pipe 2. A water inlet 19 is provided on the upper surface of the cooling water tank 15, and a water baffle 23 is provided inside the cooling water tank 15. A motor 16 is fixedly connected to the outer wall of the cooling water tank 15, and a spur gear 17 is fixedly connected to the output end of the motor 16. A gear ring 18 is meshed with the tooth end of the spur gear 17, and the inner wall of the gear ring 18 is rotatably connected to the outer wall of the second conveying pipe 2. A second spur gear 20 is meshed with the tooth end of the gear ring 18, and a rotating rod 21 is fixedly connected inside the second spur gear 20. The outer wall of the rotating rod 21 is rotatably connected to the inside of the cooling water tank 15. There is a stirring rod 22; specifically, the cooling water tank 15 is used to contain cooling water to provide a cooling environment for the slurry in the pipe, the water inlet 19 is used to replenish the cooling water tank 15, the water baffle 23 can prevent cooling water leakage, and when it is necessary to replace the cooling water or clean the water tank, the waste water in the water tank can be discharged by removing or opening the water baffle 23. When the first spur gear 17 rotates, it drives the meshing gear ring 18, and the gear ring 18 drives the meshing second spur gear 20 to rotate, so that the rotating rod 21 inside the second spur gear 20 rotates in the cooling water tank 15, which in turn drives the stirring rod 22 on the outer wall of the rotating rod 21 to rotate, thereby accelerating the flow speed of the cooling water by stirring.

[0023] Working principle: When using this device, start the delivery pump 14. The delivery pump 14 causes the slurry to pass through delivery pipe 1 and hose 5 and then enter delivery pipe 2. When it is necessary to adjust the delivery distance of the delivery device, rotate the rotating column 10. The rotating column 10 rotates inside the U-shaped block 9 and drives the bevel gear 11 to rotate. When the bevel gear 11 rotates, it causes the bevel gear 8 that is meshed with it to rotate. When the bevel gear 8 rotates, it drives the threaded rod 6 to rotate inside the fixed ring 3. During the rotation inside the fixed ring 3, since the threaded rod 6 is threadedly connected to the fixed ring 3 and the guide rod 7 restricts the rotation of the fixed ring 3, the fixed ring 3 is moved axially along the threaded rod 6, causing the hose 5 to fold. This achieves the effect of adjusting the delivery distance. Because the hose 5 is fixedly and sealed at both ends to delivery pipe 1 and fixed ring 3, it always maintains a sealed state during the distance adjustment process to avoid slurry leakage. Under the premise of ensuring sealing, the delivery distance between delivery pipe 1 and delivery pipe 2 can be flexibly adjusted, which can flexibly adapt to different delivery scenarios.

[0024] When it is necessary to cool the slurry entering the second conveying pipe 2, cooling water is added to the cooling water tank 15 through the water inlet 19. Then, the motor 16 is started. The start of the motor 16 causes the first spur gear 17 to rotate. When the first spur gear 17 rotates, it causes the gear ring 18 to rotate. When the gear ring 18 rotates, it causes the second spur gear 20, which is meshed with it, to rotate. When the second spur gear 20 rotates, it drives the stirring rod 22 to rotate inside the cooling water tank 15 through the rotation of the rotating rod 21. The rotation of the stirring rod 22 can stir the cooling water inside the cooling water tank 15, which can accelerate the flow rate of the cooling water, improve the heat exchange efficiency with the second conveying pipe 2, enhance the cooling effect, and effectively prevent the slurry from deteriorating or clogging due to high temperature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
