Description

Technical Field

[0001] This utility model relates to the technical field of ethylene bis-stearamide production equipment, specifically a stirring tank for the production of low-viscosity ethylene bis-stearamide. Background Technology

[0002] In the production process of low-viscosity ethylene bis-stearamide, the stirred tank is a key piece of equipment for mixing and reacting raw materials. The quality of its mixing directly affects the quality and performance of the final product. Currently, the stirred tanks commonly used in existing technologies typically employ fixed agitator blades. This structure, when dealing with low-viscosity materials, easily creates flow "dead zones" at the bottom and walls of the tank, leading to uneven mixing and even localized deposition and scaling, severely affecting the uniformity of product quality and batch stability.

[0003] Furthermore, to address these issues, some improved stirred tanks have attempted to introduce movable scraper bars. However, these scraper bars are prone to generating severe vibrations and harsh noises during high-speed rotation and friction with the wall surface. This not only affects the comfort of the entire production environment, but in the long run, the continuous impact loads can also damage core transmission components such as drive motors and bearings, leading to decreased equipment reliability, increased maintenance costs, and even a shortened lifespan of the entire machine.

[0004] Therefore, there is an urgent need in the field for a stirred tank for the production of low-viscosity ethylene bis-stearamide that can simultaneously achieve efficient and uniform stirring and effectively suppress vibration and noise, in order to overcome the shortcomings of the prior art.

[0014] (III) Beneficial Effects

[0015] This invention provides a stirred tank for the production of low-viscosity ethylene bis-stearamide. It has the following features:

[0016] Beneficial effects:

[0017] 1. This solution uses a secondary stirring rod consisting of a horizontal section, a vertical section, and a wall-scraping section, combined with a sliding first sliding rod and a pressure stabilizing component.

This achieves the purpose of significantly reducing vibration and noise, protecting transmission components, ensuring a smooth and reliable stirring process, and extending the service life of the equipment.

[0024] This utility model provides a stirred tank for the production of low-viscosity ethylene bis-stearamide, such as... Figure 1-4 As shown, the vessel includes a mixing tank body 11, support legs 12, mixing chamber 13, feed inlet 14, feed cylinder 15, drive shaft 16, main stirring rod 17, auxiliary stirring rod 18, drive motor 19, first sliding groove 20, first sliding rod 21, second sliding groove 22, flow limiting plate 23, pressure stabilizing plate 24, flow limiting hole 25, first damping cavity 26, second damping cavity 27, and oil bath pipe 28.

[0025] like Figure 1-4 As shown, the support leg 12 is fixedly connected to the mixing vessel body 11. The mixing vessel body 11 has a mixing chamber 13. The mixing chamber 13 has a feed inlet 14 on the side away from the support leg 12. The feed inlet 14 is fixedly connected to the feed cylinder 15. A drive shaft 16 is rotatably arranged in the mixing chamber 13. Several main stirring rods 17 are fixedly connected to the outer circumference of the drive shaft 16. A secondary stirring rod 18 is slidably arranged at the end of the drive shaft 16 away from the feed inlet 14. A pressure stabilizing component is arranged in the drive shaft 16.

[0026] It is worth noting that the auxiliary stirring rod 18 is divided into three sections: a horizontal section, a vertical section, and a wall scraping section. The section near the bottom of the stirring chamber 13 is the wall scraping section, which is adapted to the shape and size of the bottom of the stirring chamber 13. The wall scraping section can scrape off the deposits at the bottom of the stirring chamber 13 to prevent material from settling. The other two sections are fixedly connected to the first sliding rod 21, and the horizontal section is slidably connected to the second sliding groove 22.

[0027] The mixing vessel body 11 has a discharge port at one end near the support leg 12. A solenoid valve is installed in the discharge port. A drive motor 19 is fixedly connected to one end of the drive shaft 16 near the inlet 14. The base of the drive motor 19 is fixedly connected to the mixing vessel body 11. The output shaft of the drive motor 19 passes through the mixing vessel body 11 and is fixedly connected to the drive shaft 16. An oil bath pipe 28 is installed inside the mixing vessel body 11. The oil bath pipe 28 is used to regulate the temperature of the mixing vessel body 11.

[0028] A first sliding groove 20 is provided at one end of the drive shaft 16 near the auxiliary stirring rod 18. A first sliding rod 21 is slidably connected in the first sliding groove 20. The first sliding rod 21 is fixedly connected to the auxiliary stirring rod 18. A second sliding groove 22 is provided on the outer circumference of the first sliding rod 21. A voltage stabilizing component is provided at the end of the first sliding rod 21 away from the auxiliary stirring rod 18.

[0029] The pressure stabilizing assembly includes a flow limiting plate 23 and a pressure stabilizing plate 24. The flow limiting plate 23 has two flow limiting holes 25. The end of the first sliding groove 20 away from the auxiliary stirring rod 18 has a pressure stabilizing cavity. The flow limiting plate 23 is fixedly connected to the pressure stabilizing cavity, and the pressure stabilizing plate 24 is slidably connected to the pressure stabilizing cavity. The pressure stabilizing plate 24 is disposed between the flow limiting plate 23 and the first sliding groove 20.

[0030] The first sliding groove 20 divides the pressure stabilizing chamber into a first damping chamber 26 and a second damping chamber 27. The flow limiting plate 23 is disposed in the first damping chamber 26, which is filled with damping oil, and the second damping chamber 27 is filled with inert gas.

[0031] First, the operator checks the connection status of each component of the mixing vessel, ensuring that the support leg 12 is stable and the drive motor 19 is wired correctly. Then, the low-viscosity ethylene bis-stearamide raw material is fed into the mixing chamber 13 through the feed cylinder 15. At the same time, the external circulation system of the oil bath pipeline 28 is started to introduce preheated oil medium and adjust the temperature of the mixing chamber 13 to the set range, creating suitable conditions for the mixing process.

[0032] Then, the drive motor 19 is started, driving the rotating shaft 16 to begin rotating, which in turn drives the main stirring rod 17 to perform preliminary shearing and mixing of the raw materials. As the rotation speed increases, the auxiliary stirring rod 18 slides along the first sliding groove 20 via the first sliding rod 21 under the action of centrifugal force. Its scraping section moves closely against the bottom of the stirring chamber 13 to prevent the material from sticking to the wall. During this period, the pressure stabilizing component works automatically: the movement of the first sliding rod 21 causes the pressure stabilizing plate 24 to move within the pressure stabilizing chamber, and the damping oil flows through the flow limiting hole 25 between the first damping chamber 26 and the second damping chamber 27. The inert gas is compressed or expanded, generating a damping effect, stabilizing the sliding of the auxiliary stirring rod 18, reducing vibration and noise, and ensuring uniform mixing.

[0033] Finally, after the predetermined stirring time, the drive motor 19 stops running, and the stirring process ends. The operator opens the solenoid valve at the discharge port via the control system to discharge the uniformly mixed low-viscosity ethylene bis-stearamide product for further processing. Simultaneously, the oil bath circulation pipe 28 is shut off, and the mixing vessel is cleaned and maintained in preparation for the next use. The entire process is efficient and stable, effectively improving product quality and production efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
