Abstract
Description
Technical Field
[0001] This utility model is a graphite stirring vessel, belonging to the field of stirring vessel technology. Background Technology
[0002] Graphite is widely used in battery materials, lubricants, and composite materials due to its excellent electrical conductivity, high temperature resistance, and chemical stability. However, graphite processing requires mixing raw materials in a stirred tank.
[0003] Chinese patent CN119236826A discloses a stirring mechanism for a graphite reactor. This mechanism uses a drive control component to add catalyst from the stirring assembly into the reactant material, and a driving lifting component to slide the stirring assembly within the reactor, distributing the catalyst to different depths within the vessel. This stirring increases the collision frequency between the catalyst and material molecules, preventing the catalyst from failing to penetrate all layers of the material and causing varying reaction rates. However, this device uses a multi-axis stirring and lifting assembly, resulting in an overly complex structure and dead zones in the stirring, making it difficult to completely remove residual material and affecting the quality of subsequent batches. Therefore, a graphite stirred reactor is urgently needed to address these problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a graphite stirring vessel to solve the problems mentioned in the background technology. The composite vessel body of this utility model can improve its wear resistance during stirring. At the same time, the magnetic adjustable scraper structure can be used to scrape off the adhering residual materials by adhering to the inner wall of the vessel.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A graphite stirring vessel includes an outer vessel body and an inner vessel body. The inner vessel body is fixed inside the outer vessel body by brazing. A vessel cover is horizontally installed on the upper end of the inner and outer vessel bodies by bolts. A stirring motor is installed in the middle of the upper end of the vessel cover. A stirring shaft is longitudinally arranged inside the inner vessel body. A spur gear is fixed to the upper end of the stirring shaft. Multiple sheet-like stirring blades are welded to the left and right sides of the outside of the stirring shaft. Two spiral stirring blades are welded intersectingly between the multiple sheet-like stirring blades. A metal fixing ring is horizontally welded to the lower end of the vessel cover. Multiple electromagnet blocks are adhered inside the metal fixing ring. The lower end of the metal fixing ring is attracted and fixed to a magnetic ring by magnetism. A rotating disk is adhered to the lower end of the magnetic ring by epoxy resin. Arc-shaped scrapers are symmetrically welded to the left and right sides of the lower end of the rotating disk. A stepped ring is welded in the middle of the rotating disk. The inner edge of the stepped ring is provided with inner annular teeth. The stepped ring slides through the outside of the stirring shaft. The inner annular teeth are located directly above the spur gear.
[0006] Furthermore, the two arc-shaped scrapers slide against the left and right sides of the inner wall of the inner vessel, respectively.
[0007] Furthermore, the multiple electromagnet blocks and the stirring motor are connected to an external PLC controller via wires, and all of the multiple electromagnet blocks are in a de-energized state.
[0008] Furthermore, the end of the stirring motor shaft is connected to the stirring shaft via a drive connection.
[0009] Furthermore, a discharge pipe is installed through the lower ends of the inner and outer vessels, and a feeding pipe is installed through the right front end of the inner and outer vessels.
[0010] Furthermore, the outer vessel body is made of Q345R carbon steel, and the inner vessel body is made of silicon carbide ceramic.
[0011] The beneficial effects of this utility model are as follows: This utility model is a graphite stirring vessel. Because it adds an outer vessel body, an inner vessel body, spiral stirring blades, sheet-shaped stirring blades, spur gears, stepped rings, inner annular teeth, a rotating disk, a magnetic ring, a metal fixing ring, an electromagnet block, and an arc-shaped scraper, the structure is reasonable. The use of a composite vessel body can improve its wear resistance during stirring. At the same time, the magnetic adjustable scraper structure can adhere to the inner wall of the vessel to scrape away the adhering residual materials. The structure is simple and highly practical.

Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] Please see Figures 1-3 This utility model provides a technical solution: a graphite stirring vessel, including an outer vessel body 3 and an inner vessel body 4. The inner vessel body 4 is fixed inside the outer vessel body 3 by brazing. A vessel cover 2 is horizontally installed on the upper end of the inner vessel body 4 and the outer vessel body 3 by bolts. A stirring motor 1 is installed in the middle of the upper end of the vessel cover 2. A stirring shaft 6 is longitudinally arranged inside the inner vessel body 4. A spur gear 9 is fixed on the upper end of the outside of the stirring shaft 6. Multiple sheet-like stirring blades 8 are welded on the left and right sides of the outside of the stirring shaft 6. Two spiral stirring blades 7 are welded intersectingly between the multiple sheet-like stirring blades 8. A metal fixing ring 14 is horizontally welded to the lower end of the vessel cover 2. Multiple electromagnet blocks 1 are adhered inside the metal fixing ring 14. 5. The lower end of the metal fixing ring 14 is magnetically attracted and fixed to the magnetic suction ring 13 by a magnet. The lower end of the magnetic suction ring 13 is glued to the rotating disk 12 with epoxy resin. The lower end of the rotating disk 12 is symmetrically welded with arc-shaped scrapers 16 on the left and right sides. The middle of the rotating disk 12 is welded with a stepped ring 10. The inner edge of the stepped ring 10 is provided with inner annular teeth 11. The stepped ring 10 slides through the outside of the stirring shaft 6. The inner annular teeth 11 are located directly above the spur gear 9. This design solves the problem that the original graphite reactor stirring mechanism uses multi-axis stirring and lifting components, which has a complex structure and has stirring dead corners, making it difficult to completely remove residual materials and affecting the quality of subsequent batches.
[0019] As the first embodiment of this utility model: two arc-shaped scrapers 16 slide and adhere to the left and right sides of the inner wall of the inner vessel 4 respectively. By adding two arc-shaped scrapers 16 that slide and adhere to the left and right sides of the inner wall of the inner vessel 4 respectively, the residual graphite material on the inner wall of the inner vessel 4 can be scraped off when the two arc-shaped scrapers 16 rotate.
[0020] Multiple electromagnet blocks 15 and a stirring motor 1 are connected to an external PLC controller via wires. All electromagnet blocks 15 are in a de-energized state. The added electromagnet blocks 15, stirring motor 1, and external PLC controller are all existing mature technologies, and their control principles will not be elaborated upon. The shaft end of stirring motor 1 is connected to stirring shaft 6 via a drive connection. When the shaft end of stirring motor 1 rotates, it drives stirring shaft 6 to rotate as well. A discharge pipe is installed through the lower ends of the inner vessel 4 and the outer vessel 3. A feeding pipe 5 is installed through the front right side of the inner vessel 4 and the outer vessel 3. The outer vessel 3 is made of Q345R carbon steel, and the inner vessel 4 is made of silicon carbide ceramic. The addition of the Q345R carbon steel outer vessel 3 provides shielding and protection for the inner vessel 4. The inner vessel 4 is made of silicon carbide ceramic, which is 2mm thick, has a wear resistance coefficient ≤0.01mm / thousand batches, and a surface roughness Ra≤0.4μm, effectively reducing the adhesion of graphite materials.
[0021] As a second embodiment of this utility model: when graphite raw material is added into the inner vessel 4, the stirring motor 1 is started. The stirring motor 1 drives the stirring shaft 6 to rotate, thereby causing multiple stirring shafts 6 and two spiral stirring blades 7 to rotate, thus achieving stirring of the graphite raw material. When it is necessary to remove residual graphite material from the inner wall of the inner vessel 4, multiple electromagnet blocks 15 are energized, causing a repulsive magnetic field to appear between the lower end of the electromagnet block 15 and the upper surface of the magnetic ring 13, thereby pushing the magnetic ring 13 to separate from the metal fixing ring 14. This causes the rotating disk 12 to move downwards within the inner vessel 4 until the inner annular teeth 11 are fitted onto the outside of the spur gear 9 and mesh with the outer side of the spur gear 9. At this time, the two arc-shaped scrapers 16 slide against the inner wall of the inner vessel 4. When the stirring shaft 6 is driven to rotate, it can drive the spur gear 9 to rotate. The inner annular teeth 11 mesh with it, driving the stepped ring 10, the rotating disk 12, and the magnetic ring 13 to rotate. This allows the two arc-shaped scrapers 16 to be driven to rotate as well, thereby achieving the removal of residual graphite material from the inner wall of the inner vessel 4 by rotary scraping.
