Description

Technical Field

[0001] This invention relates to the field of chemical production equipment technology, specifically to a continuous thermal polymerization reactor for preparing asphalt with high mesophase content. Background Technology

[0002] High mesophase pitch is an intermediate product in the preparation of graphitized foamed carbon. It is produced by the polymerization reaction of pitch materials at high temperatures. In the preparation of high mesophase pitch, a heating kettle is needed to slowly heat the material to the polymerization reaction temperature and maintain it. Then, the product that meets the parameter indicators is obtained through the polymerization reaction of the material. Most of the existing equipment suitable for small-scale production is a reactor structure, which processes the raw materials required for the reaction in one go.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1-8 As shown, the specific implementation adopts the following technical solution: This specific embodiment includes a reaction vessel 1, a top cover 2, a stirring mechanism 4, and a homogenizing mechanism 5. The top cover 2 covers the upper port of the reaction vessel 1. A support shaft 6 is screwed onto the top cover 2 via bearings. A rotating frame 3 is fixedly mounted on the lower end of the support shaft 6 and is located inside the top cover 2. The stirring mechanism 4 and the homogenizing mechanism 5 are both mounted on the rotating frame 3, and their lower ends extend into the reaction vessel 1. A rotary motor 7 is fixedly mounted on the upper side wall of the top cover 2, and the output shaft of the rotary motor 7 is connected to the upper end of the support shaft 6 for transmission. The stirring mechanism 4 includes a stepper motor screw 4-1, a mounting frame 4-2, a stirring frame 4-4, and a stirring shaft 4-3. The stepper motor screw 4-1 is fixedly mounted on the lower side wall of the rotating frame 3. The mounting frame 4-2 is fixedly mounted on the movable end of the stepper motor screw 4-1. The stirring shaft 4-3 is spun onto the mounting frame 4-2 via bearings. The stirring frame 4-4 is fixedly mounted on the lower end of the stirring shaft 4-3. Two stirring rollers 4-5 are fixedly mounted at both ends of the stirring frame 4-4. The stirring shaft 4-3 rotates, causing the stirring frame 4-4 to rotate, which in turn causes the stirring rollers 4-5 to rotate, thus stirring the material in the reactor 1. The stepper motor screw 4-1 moves the mounting frame 4-2, thereby moving the mounting frame 4-2 and adjusting the position of the stirring frame 4-4 relative to the center line of the reactor 1, achieving stirring of the raw materials in different areas within the reactor 1. A connecting frame 8 is fixedly installed on the lower side wall of the rotating frame 3, and the connecting frame 8 is located on the side of the mounting frame 4-2 facing the support shaft 6. A drive shaft 9 is screwed through the connecting frame 8 via a bearing. A stirring motor 10 is fixedly installed on the rotating frame 3. The output shaft of the stirring motor 10 is connected to the drive shaft 9 via a coupling unit. A transmission spline sleeve 11 is screwed through the mounting frame 4-2 via a bearing, and the transmission spline sleeve 11 is connected to the stirring shaft 4-3 via a bevel gear set. A transmission spline rod 12 is movably inserted inside the transmission spline sleeve 11, and the transmission spline rod 12 is connected to the drive shaft 9 via a jaw clutch. A spring 13 is sleeved on the end of the transmission spline rod 12 facing the drive shaft 9, and the spring 13... One end of the spring 13 is fixedly mounted on the transmission spline rod 12, and the other end of the spring 13 is fixedly mounted on the transmission spline sleeve 11. The stepper electric lead screw 4-1 drives the mounting bracket 4-2 to move, and the mounting bracket 4-2 drives the transmission spline sleeve 11 to move. The spring 13 abuts against the transmission spline rod 12, so that the clutch unit between the transmission spline rod 12 and the drive shaft 9 is closed. As the mounting bracket 4-2 continues to move, it drives the transmission spline sleeve 11 to slide on the transmission spline rod 12 and presses the spring 13. The stirring motor 10 drives the drive shaft 9 to rotate. The drive shaft 9 drives the transmission spline rod 12 to rotate through the dog clutch. The transmission spline rod 12 drives the transmission spline sleeve 11 to rotate. The transmission spline sleeve 11 drives the stirring shaft 4-3 to rotate through the bevel gear set. The homogenization mechanism 5 includes a lifting frame 5-1, a main homogenizing disk 5-3, and a secondary homogenizing disk 5-5. The lifting frame 5-1 is fixedly mounted on the rotating frame 3 at one end away from the stepper electric screw 4-1. A lifting electric screw 5-2 is fixedly mounted on the lifting frame 5-1. The main homogenizing disk 5-3 is fixedly mounted on the movable end of the lifting electric screw 5-2. A drive shaft 5-4 is spun onto the lower side wall of the main homogenizing disk 5-3 via a bearing. The secondary homogenizing disk 5-5 is fixedly mounted at the lower end of the drive shaft 5-4. The lifting electric screw 5-2 drives the main homogenizing disk 5-3 to move up and down, thereby driving the secondary homogenizing disk 5-5 to move. This adjusts the vertical height of the main homogenizing disk 5-3 and the secondary homogenizing disk 5-5 within the reactor 1. The rotation of the secondary homogenizing disk 5-5 allows it to cooperate with the main homogenizing disk 5-3 to shear and stir the material, thereby accelerating the contact and fusion of microcrystalline spheres in the material. A main guide groove 14 is formed on the main homogenizing disk 5-3 below the stepper electric lead screw 4-1. Several secondary guide grooves 15 are formed on the secondary homogenizing disk 5-5 at equal angles, with one of the secondary guide grooves 15 located below the main guide groove 14. When the secondary homogenizing disk 5-5 is stopped, one of its secondary guide grooves 15 is aligned below the main guide groove 14. During stirring by the stirring roller 4-5, the main homogenizing disk 5-3 is raised, causing the stirring frame 4-4 to be positioned below the secondary homogenizing disk. Below the main homogenizing disk 5-5, the mounting bracket 4-2 is moved by the stepper screw 4-1, which in turn moves the stirring shaft 4-3 within the main guide groove 14 and the secondary guide groove 15. When the main homogenizing disk 5-3 and the secondary homogenizing disk 5-5 are working, the mounting bracket 4-2 is moved by the stepper screw 4-1, which moves the stirring shaft 4-3 and the stirring bracket 4-4 to the outer side of the outer ring edge of the main homogenizing disk 5-3 and the secondary homogenizing disk 5-5, thereby causing the secondary homogenizing disk 5-5 to rotate. A lifting spline rod 17 is screwed onto the lifting frame 5-1 via bearings, and the lifting spline rod 17 is arranged parallel to the lifting electric lead screw 5-2. A homogenizing motor 19 is fixedly mounted on the rotating frame 3, and the output shaft of the homogenizing motor 19 is connected to the upper shaft of the lifting spline rod 17 via a coupling unit. A lifting spline sleeve 18 is movably sleeved on the lifting spline rod 17, and the lifting spline sleeve 18 is screwed onto the main homogenizing disk 5-3 via bearings. A driven motor is screwed onto the main homogenizing disk 5-3 via bearings. Shaft 16 is connected to drive shaft 5-4 via a spur gear set, and driven shaft 16 is connected to lifting spline sleeve 18 via a coupling unit. The lifting spline rod 17 is driven to rotate by homogenizing motor 19, which in turn drives lifting spline sleeve 18 to rotate. Lifting spline sleeve 18 drives driven shaft 16 to rotate via coupling unit, and driven shaft 16 drives drive shaft 5-4 to rotate via spur gear set. Drive shaft 5-4 drives secondary homogenizing disk 5-5 to rotate.

[0025] When using this device, the material is put into the reactor 1 and the top cover 2 is fastened, so that the stirring roller 4-5 and the lifting frame 5-1 are inserted into the reactor 1. When the material is heated from a low temperature, it is stirred by the stirring roller 4-5. First, the position of the secondary homogenizing disk 5-5 is adjusted by the homogenizing motor 19 so that one of the secondary guide grooves 15 is aligned and placed below the main guide groove 14. The main homogenizing disk 5-3 is raised by the lifting electric screw 5-2 so that the secondary homogenizing disk 5-5 is set higher than the stirring frame 4-4. Then, the mounting frame 4-2 is moved by the stepper electric screw 4-1 so that the mounting frame 4-2 drives the stirring shaft 4-3 to slide into the main guide groove 14 and the secondary guide groove 15. The mounting frame 4-2 drives the transmission spline sleeve 11 to move. The spring 13 abuts against the transmission spline rod 12, so that the jaw clutch between the transmission spline rod 12 and the drive shaft 9 is engaged. As the mounting frame 4-2 continues to move, it causes the transmission spline sleeve 11 to slide on the transmission spline rod 12 and press the spring 13. The stirring motor 10 drives the drive shaft 9 to rotate through the coupling unit. The drive shaft 9 drives the transmission spline rod 12 to rotate through the jaw clutch. The transmission spline rod 12 drives the transmission spline sleeve 11 to rotate. In turn, the transmission spline sleeve 11 drives the stirring shaft 4-3 to rotate through the bevel gear set. The stirring shaft 4-3 drives the stirring frame 4-4 and the stirring roller 4-5 to rotate. The rotating motor 7 drives the support shaft 6 to rotate. The support shaft 6 drives the rotating frame 3 to rotate. Thus, the rotating frame 3 drives the stirring frame 4-4 and the stirring roller 4-5 to rotate. Thus, the stirring of the material in the reactor 1 is achieved through the rotation of the stirring roller 4-5 and the revolution driven by the rotating frame 3, and by adjusting the revolution radius of the stirring roller 4-5 through the stepper electric screw 4-1.When the material reaches the required temperature and begins the polymerization reaction, the main homogenizing disk 5-3 and the secondary homogenizing disk 5-5 homogenize the material, causing the microcrystalline particles to contact each other and accelerating polymerization. The stepper motor screw 4-1 drives the mounting frame 4-2 to move away from the support shaft 6, causing the mounting frame 4-2 to move the stirring shaft 4-3 out of the main guide groove 14. This moves the stirring shaft 4-3 and the stirring frame 4-4 to the outer side of the outer ring of the main homogenizing disk 5-3, and the two stirring rollers 4-5 to press against the inner wall of the reactor 1. At this time, the spring 13 opens, and the jaw clutch between the transmission spline rod 12 and the drive shaft 9 disengages. Then, the lifting motor... Screw 5-2 drives the main homogenizing disk 5-3 to move up and down, thereby adjusting the height of the main homogenizing disk 5-3 and the secondary homogenizing disk 5-5 within the reactor 1. The homogenizing motor 19 drives the lifting spline rod 17 to rotate, which in turn drives the lifting spline sleeve 18 to rotate. The lifting spline sleeve 18, through a coupling unit, drives the driven shaft 16 to rotate. The driven shaft 16, through a spur gear set, drives the drive shaft 5-4 to rotate, which in turn drives the secondary homogenizing disk 5-5 to rotate. The cooperation between the main homogenizing disk 5-3 and the secondary homogenizing disk 5-5 achieves shearing and stirring of the material, improving the contact efficiency of the microcrystalline particles and accelerating the polymerization reaction.

[0026] Compared with the prior art, the beneficial effects of the present invention are: 1. This device, by setting up a stirring mechanism 4 and a homogenizing mechanism 5, achieves the following: during the material polymerization reaction, the material is stirred when it is heated to ensure uniform heating, and the material is homogenized and stirred during polymerization and crystallization to accelerate the polymerization rate of the microcrystalline spheres. 2. This device uses a rotating frame 3 to set a stepper electric screw 4-1, and a stirring shaft 4-3 is set on the stepper electric screw 4-1. The stirring frame 4-4 and the stirring roller 4-5 are set on the stirring shaft 4-3. Thus, through the rotation of the rotating frame 3, the movement of the mounting base and the rotation of the stirring shaft 4-3, the stirring roller 4-5 can fully and evenly stir the material in the reaction vessel 1, so that the material is heated evenly. 3. This device sets the main homogenizing disk 5-3 through the lifting electric screw 5-2, and rotates the secondary homogenizing disk 5-5 onto the main homogenizing disk 5-3 through the drive shaft 5-4. Thus, the rotation of the secondary homogenizing disk 5-5 realizes the shearing and stirring of the material, accelerating the polymerization of the material.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
