Description

Technical Field

[0001] This patent relates to the field of solid mixing technology, specifically a solid mixing and conveying device. Background Technology

[0002] Solid mixing primarily involves the mixing of solid polymers with each other and with other solid components, such as additives. At lower temperatures, polymers are typically in powder, granular, or flake form, while additives are usually also in powder or granular form. In polymer processing, this type of mixing is called dry mixing. In most cases, this mixing precedes melt mixing. Solid-to-solid mixing is usually a random, non-dispersed mixture; however, current solid mixing and conveying devices are all modular, resulting in large installation spaces, poor sealing, significant pollution, and cumbersome operation. Summary of the Invention

[0017] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] Please see Figure 1-3 This patent provides a technical solution: a solid mixing and conveying device, including a first motor reducer 1 and a frame 3. The first motor reducer 1 is fixed on the frame 3. A first coupling 2 is installed on the output shaft of the first motor reducer 1. The output shaft of the first motor reducer 1 is connected to a stirring rod 6 through the first coupling 2. The stirring rod 6 is rotatably connected to a crossbeam in the middle of the frame 3 through a bearing. A mechanical seal 4 is fitted on the stirring rod 6. The mechanical seal 4 and the frame 3 are fixed on the flange of a reaction tank 5. A linkage valve 7 is connected to the bottom discharge flange of the reaction tank 5. The feed flange of a conveying cylinder 12 is connected below the linkage valve 7. A first sealing support 10 is installed at one end of the conveying cylinder 12, and a second sealing support 13 is installed at the other end of the conveying cylinder 12. The first sealing support 10 and the second sealing support 13 are connected... A conveying screw 11 is rotatably installed between the sealing support base 13. The conveying screw 11 is driven to rotate by the second motor reducer 8 and the second coupling 9 to transport the material from the feed port of the conveying cylinder 12 to the discharge port of the conveying cylinder 12. This device is an integrated unit with a small installation space and simple operation. Moreover, it adopts a mechanical seal 4 to avoid droplets during the solid mixing process and avoid air pollution. During operation, external solid materials are discharged into the reaction tank 5 through the inlet. At this time, the first motor reducer 1 drives the first coupling 2 to rotate, causing the stirring rod 6 to rotate and stir the solid materials. After stirring is completed, the linkage valve 7 opens, and the material is discharged into the conveying cylinder 12. Meanwhile, the second motor reducer 8, in conjunction with the second coupling 9, drives the conveying screw 11 to rotate and transport the material from the feed port of the conveying cylinder 12 to the discharge port of the conveying cylinder 12 for discharge.

[0019] The reaction vessel 5 consists of a top cover 14 and a conical cylinder 15. The mechanical seal 4 and the frame 3 are fixed on the flange of the top cover 14. An inlet is reserved on the top cover 14. A linkage valve 7 is connected to the bottom discharge flange of the conical cylinder 15.

[0020] The top cover 14 and the conical cylinder 15 are connected by a snap-fit ​​structure 18. There are no fewer than eight snap-fit ​​structures 18, which are distributed in a ring at equal intervals between the top cover 14 and the conical cylinder 15. Each snap-fit ​​structure 18 includes a snap-fit ​​block 19 and a snap-fit ​​groove 20. The snap-fit ​​block 19 is installed on the conical cylinder 15, and the snap-fit ​​groove 20 is opened on the top cover 14. The snap-fit ​​block 19 snaps into the snap-fit ​​groove 20. The snap-fit ​​groove 20 on the top cover 14 is snapped into the snap-fit ​​block 19 on the conical cylinder 15, so that the top cover 14 and the conical cylinder 15 are quickly connected. Conversely, it is convenient to disassemble, clean or repair.

[0021] A spiral rod 22 is installed on the stirring rod 6. The spiral rod 22 is placed inside the linkage valve 7 and above the valve body inside the linkage valve 7. The spiral rod 22 has a threaded groove 24. A bolt 23 is installed on the stirring rod 6 and is fitted into the threaded groove 24. The threaded groove 24 on the spiral rod 22 is screwed onto the bolt 23 on the stirring rod 6. While the stirring rod 6 is rotating and mixing solid materials inside the conical cylinder 15, the spiral rod 22 is also rotating inside the linkage valve 7 to prevent blockage during material discharge.

[0022] An annular groove 16 is provided inside the conical cylinder 15, and a rubber ring 17 is placed inside the annular groove 16. When the top cover 14 is placed on the conical cylinder 15, the rubber ring 17 inside the annular groove 16 presses against the top cover 14, sealing the gap between the fixed rod 14 and the conical cylinder 15.

[0023] An elastic element 21 is installed inside the locking block 19. The elastic element 21 is correspondingly set to the locking block 19. The elastic element 21 is made of steel to enhance the elasticity of the locking block 19.

[0024] When using this solid mixing and conveying device, firstly, screw the threaded groove 24 on the screw rod 22 onto the bolt 23 on the stirring rod 6, and then engage the slot 20 on the top cover 14 with the locking block 19 on the conical cylinder 15, so that the top cover 14 and the conical cylinder 15 are quickly connected. When the top cover 14 is on the conical cylinder 15, the rubber ring 17 in the annular groove 16 presses against the top cover 14, sealing the gap between the fixed rod 14 and the conical cylinder 15. During operation, external solid materials are discharged through the inlet of the reaction tank 5. At this time, the first motor decelerates. Machine 1 drives the first coupling 2 to rotate, causing the stirring rod 6 to rotate and stir the solid material. After stirring, the linkage valve 7 opens, and the material is discharged into the conveying cylinder 12. Meanwhile, the second motor reducer 8, linked with the second coupling 9, drives the conveying screw 11 to rotate and transport the material from the feed port of the conveying cylinder 12 to the discharge port of the conveying cylinder 12 for discharge. During the mixing process of the stirring rod 6 in the conical cylinder 15, the screw rod 22 also rotates in the linkage valve 7 to prevent blockage during the material discharge process.
