Description

Technical Field

[0001] This utility model relates to the field of coated asphalt production technology, specifically a reaction vessel for heating high-soft-point coated asphalt. Background Technology

[0002] Lithium-ion batteries, as a new generation of energy storage power sources, possess numerous advantages such as high energy density, long cycle life, low self-discharge, wide operating temperature range, and environmental friendliness. They have been widely used in portable electronic products and power tools, and are gradually expanding into high-tech fields such as electric vehicles, mobile communications, military equipment, and aerospace. The negative electrode material is one of the key factors in evaluating the overall performance of lithium-ion batteries. Currently, the main negative electrode material used in lithium-ion batteries is graphite-based carbon material that has undergone coating modification. This involves using high-soft-point asphalt coating to reduce the specific surface area of ​​the graphite-based carbon material, thereby improving the charge-discharge efficiency and cycle performance of the lithium-ion battery. The production process of lithium-ion battery negative electrode materials requires the use of an asphalt reactor. An asphalt reactor is a pressure vessel used to heat and mix asphalt, ensuring that the additives and asphalt in the reactor are mixed evenly.

[0003] Chinese patent document CN216458815U discloses a lithium battery-grade asphalt polymerization reactor, which includes a reactor tank, a feed pipe, and a mounting cover. The top of the reactor tank is fixed with the mounting cover and two feed pipes. A mounting plate is movably arranged inside the mounting cover, and a bidirectional motor is fixedly installed inside the mounting plate. A vertical shaft is fixedly installed at the bottom of the bidirectional motor, and multiple stirring rods are fixedly installed on both sides of the vertical shaft. By rotating and raising the stirring rods, the stirring area is increased, and the stirring effect is improved. Although this reactor can be used for asphalt coating production, the following problems exist in actual use: 1. Due to the strong adhesion of asphalt, it easily adheres to the end of the cleaning brush and the inner wall of the reactor, making the cleaning effect of the cleaning brush on the inner wall of the reactor relatively limited; 2. The stirring rods are driven by a worm gear mechanism, which has a slow rotation speed, resulting in a long time for the stirring rods to rise and then fall again. This leads to insufficient stirring of the asphalt at the bottom of the reactor, causing asphalt to accumulate at the bottom of the reactor and affecting the production quality of the coated asphalt. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a high soft point coated asphalt heating reactor, which overcomes the shortcomings of the above-mentioned prior art.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1:

[0019] As attached Figure 1-2As shown, this utility model provides a reactor for heating high-soft-point coated asphalt, including a reactor lid 1, a reactor body 2, an intermediate stirring shaft 3 and an auxiliary stirring frame 4 installed in the reactor body 2. A planetary gear drive device 5 is provided at the upper end of the reactor lid 1, and a drive motor 6 is provided at the upper end of the planetary gear drive device 5. The drive motor 6 is connected to the intermediate stirring shaft 3 and can drive it to rotate. The planetary gear drive device 5 includes a sun gear 503 and a planet carrier 504. The sun gear 503 is connected to the drive motor 6 and can drive it to rotate. The planetary carrier 504 rotates, and its lower end is connected to the auxiliary stirring frame 4, which can drive the planetary carrier 504 to rotate. The vessel cover 1 is provided with a feed inlet 7 and an exhaust outlet 8. The reactor body 2 is provided with a reactor cavity inside. The side wall of the reactor body 2 is provided with a heating device 9. The lower end of the reactor body 2 is provided with a discharge port 10. Several central shaft stirring blades 301 are provided axially at intervals on the outer side of the central stirring shaft 3. The lower end of the central stirring shaft 3 is provided with a lower scraper 302. The auxiliary stirring frame 4 includes an auxiliary frame base 401, radial support rods 402, axial support rods 403, and side scrapers. The auxiliary frame 404 and auxiliary frame stirring blade 405 are provided. The auxiliary frame base 401 is cup-shaped and is mounted on the vessel cover 1 through a base bearing 406. The upper end of the auxiliary frame base 401 is fixedly connected to the lower end of the planetary carrier 504. The bottom of the cup body of the auxiliary frame base 401 is provided with an auxiliary frame seat hole and a stirring bearing 407 is installed. The upper part of the intermediate stirring shaft 3 is installed in the auxiliary frame base 401 through the stirring bearing 407. The lower part of the intermediate stirring shaft 3 is located in the reaction vessel cavity below the auxiliary frame base 401. The lower outer side of the auxiliary frame base 401 is provided with not less than two radial blades at intervals. The radial support rods 402 are evenly and symmetrically arranged around the outer circumference of the auxiliary support base 401. The lower end of each radial support rod 402 is fixedly connected to an axial support rod 403. A side scraper 404 is provided on the side of the axial support rod 403 near the side wall of the reactor cavity. The side scraper 404 movably abuts against the side wall of the reactor cavity. An auxiliary frame stirring blade 405 is provided on the side of the axial support rod 403 away from the side wall of the reactor cavity. The auxiliary frame stirring blade 405 is interspersed between two adjacent central axis stirring blades 301. The auxiliary stirring frame 4 is driven to rotate by the planetary gear drive device 5. The side scraper 404 on the outer side of the auxiliary stirring frame 4 continuously scrapes the inner wall of the reactor body 2 to prevent the coated asphalt from adhering to the inner wall of the reactor body 2, thus improving the working effect. The auxiliary frame stirring blades 405 are interspersed between two adjacent central shaft stirring blades 301, and the central stirring shaft 3 and the auxiliary stirring frame 4 rotate at different speeds, which effectively improves the stirring effect. Due to the high viscosity of the coated asphalt, the resistance of the auxiliary stirring frame 4 during rotation is large. The planetary gear drive device 5 can reduce the speed, effectively increasing the torque output of the auxiliary stirring frame 4 and ensuring the normal operation of the equipment.The side scraper 404 on the auxiliary stirring frame 4 scrapes off the asphalt coating adhering to the side wall of the reactor body 2, while also pushing the mixture in the reactor cavity. Due to the speed difference between the intermediate stirring shaft 3 and the auxiliary stirring frame 4, the central shaft stirring blade 301 on the intermediate stirring shaft 3 stirs in the reactor cavity, and together with the auxiliary frame stirring blade 405 on the auxiliary stirring frame 4, forces the mixture in the reactor body 2 to collide and rub, thereby improving the stirring efficiency. The auxiliary frame base 401 not only supports the planetary frame 504 and transmits the driving force of the planetary frame 504 to the auxiliary stirring frame 4, but also effectively prevents asphalt splashing from contaminating the planetary frame 504. The lower scraper 302 at the lower end of the intermediate stirring shaft 3 can stir the mixture at the bottom of the reactor body 2, improving the stirring effect and avoiding the bottoming phenomenon. It has the characteristics of high stirring efficiency, good stirring effect, simplicity, reliability and high efficiency.

[0021] As attached Figure 1-2 As shown, the difference between this embodiment and Embodiment 1 is that the planetary gear drive device 5 further includes a transmission housing 500, a gear ring 501, a drive shaft 502, and planetary gears 505. The transmission housing 500 is fixedly installed in the middle of the upper end of the vessel lid 1, and the drive motor 6 is fixedly installed in the middle of the upper end of the transmission housing 500. The gear ring 501, drive shaft 502, sun gear 503, planet carrier 504, and planetary gears 505 are all located inside the transmission housing 500. The lower end of the gear ring 501 is fixedly installed in the upper end of the vessel lid 1. The drive shaft 502 is mounted on the upper end of the transmission housing 500 via bearings and is concentric with the axis of the gear ring 501. The upper end of the drive shaft 502 extends above the transmission housing 500 and is connected to the output shaft of the drive motor 6. A sun gear 503 is fixedly mounted in the middle of the drive shaft 502, and the lower end of the drive shaft 502 is connected to the upper end of the intermediate stirring shaft 3. The planetary carrier 504 is triangular, and planetary gears 505 are provided at each of its three corners. The planetary gears 505 mesh with the gear ring 501 and the sun gear 503 and can drive the planetary carrier 504 to rotate.

The lower end of the planetary carrier 504 is welded and fixed to the upper end of the auxiliary frame base 401. The drive motor 6 with a reducer can achieve speed reduction, thereby effectively increasing the torque output of the intermediate mixing shaft 3, achieving uniform mixing of the relatively viscous coated asphalt, and resulting in better mixing effect.

[0024] Example 4:

[0025] As attached Figure 1 As shown, the difference between this embodiment and embodiments 1-3 is that the heating device 9 includes an insulation layer 901 and a heating coil 902. The insulation layer 901 is provided inside the side wall of the reactor body 2, and the heating coil 902 is spirally wound inside the insulation layer 901.

The heating coil 902, wound inside the insulation layer 901, can uniformly heat the reactor body 2. The insulation layer 901 further improves the insulation effect of the reactor body 2. High-temperature oil is introduced into the heating coil 902 through the thermal oil heater to heat the interior of the reactor cavity of the reactor body 2, achieving uniform heating of the mixture inside the reactor cavity, thereby effectively ensuring the quality of the resulting coated asphalt.

[0026] Example 5:

[0027] As attached Figure 1 As shown, the difference between this embodiment and embodiments 1-4 is that the bottom of the reactor cavity is an inverted cone shape, wider at the top and narrower at the bottom. The discharge port 10 is located at the apex of the inverted cone, and the lower side of the lower scraper 302 is an inclined surface adapted to the bottom of the reactor cavity. Designing the bottom of the reactor cavity as an inverted cone shape facilitates the complete discharge of the coated asphalt inside the reactor cavity. The inclined surface of the lower scraper 302 can better scrape off the coated asphalt adhering to the bottom of the reactor cavity, resulting in better performance.

[0028] Example 6:

[0029] As attached Figure 1As shown, the difference between this embodiment and embodiments 1-5 is that a discharge device 11 is provided at the discharge port 10 corresponding to the reactor body 2. The discharge device 11 includes a discharge cylinder 1101, a discharge horizontal pipe 1102, a discharge valve 1103, a discharge shaft 1104, an auger blade 1105, and a discharge motor 1106. The discharge cylinder 1101 is integrally connected to the lower end of the reactor body 2 at the discharge port 10. The discharge cylinder 1101 has an inner cavity with its upper end connected to the discharge port 10. The lower outer sides of the discharge cylinder 1101 are on the left and right sides. The discharge horizontal pipe 1102 with discharge valve 1103 is provided on both sides.

The lower end of the discharge shaft 1104 is connected to the upper end of the output shaft of the discharge motor 1106. After opening the discharge valve 1103, start the discharge motor 1106. The discharge motor 1106 drives the discharge shaft 1104 and the auger blades 1105 to rotate, which can evenly transfer the coated asphalt in the reactor cavity from the discharge port 10 to the discharge horizontal pipe 1102. The auger blades 1105 can effectively prevent material jamming and ensure smooth discharge. By setting two discharge horizontal pipes 1102, material can be discharged from both sides at the same time or from one side, making discharge more convenient.

[0031] As attached Figure 1 As shown, the difference between this embodiment and embodiments 1-6 is that the lower end of the reactor body 2 is provided with support legs, and the lower end of the support legs is provided with leveling feet (not shown in the attached drawings). There are three or four support legs, which are evenly spaced at the lower part of the reactor body 2, making the reactor body 2 more stable.
