Description

Technical Field

[0001] This utility model relates to the field of boron nitride production technology, and in particular to an emulsification device for boron nitride production. Background Technology

[0002] Boron nitride coatings are inert inorganic high-temperature lubricating materials that do not adhere to or wet molten metal. They can completely protect the surfaces of refractory materials or ceramic vessels that come into direct contact with molten aluminum, magnesium, zinc alloys, and slag, greatly extending the service life of such vessels. In the production of boron nitride coatings, boron nitride particles and aqueous solutions need to be emulsified with an emulsifier to form an emulsion for easy use. Currently, emulsification equipment for boron nitride production is widely used for the emulsification process of boron nitride.

[0003] Currently, Chinese utility model patent CN217473195U discloses an emulsification device for boron nitride production. This utility model discloses an emulsification device for boron nitride production, including a mounting bearing frame, a triangular box, and emulsification tanks. A rotating shaft is mounted on the mounting bearing frame, and a triangular box is fixedly mounted on the rotating shaft. Emulsification tanks are evenly fixedly mounted on three sides of the triangular box. A driving bevel gear is mounted on the rotating shaft within the triangular box. A stirring shaft is mounted inside each of the three emulsification tanks, and a driven bevel gear is mounted at one end of the stirring shaft within the triangular box. The driven bevel gear meshes with the driving bevel gear. Several homogenizing rods are evenly mounted on the stirring shaft. This utility model, with its triangular box and emulsification tanks, utilizes the driving bevel gear to drive the driven bevel gear, achieving the goal of simultaneously driving three emulsification tanks for emulsification operations using only one servo motor housing. This not only reduces the manufacturing cost of an emulsification device for boron nitride production but also reduces the electrical energy consumption required for boron nitride emulsification production.

[0004] Existing emulsification equipment for boron nitride production has the following drawbacks: its internal mixing structure generally uses either a stirring rod or a stirring blade, resulting in poor mixing efficiency due to the use of only one stirring method; and the material tends to stick to the walls during the emulsification process, which hardens and adheres after prolonged use, leading to material waste and making subsequent cleaning difficult. Therefore, improvements are proposed to address these issues. Utility Model Content

[0027] The wall scraping assembly 7 includes a connecting shaft 701, a scraper plate 702, and a scraper rod 703. The connecting shaft 701 is fixedly connected to the bottom of the double stirring assembly 6. The connecting shaft 701 is located on the bottom side inside the high-pressure emulsifying tank 1. The scraper plate 702 is bolted to both sides of the connecting shaft 701 and fixed. The scraper plate 702 is in contact with the bottom side inside the high-pressure emulsifying tank 1. The scraper rod 703 is bolted to the outer side of the top of the scraper plate 702. The outer side of the scraper rod 703 is in contact with the inner wall inside the high-pressure emulsifying tank 1.

[0028] In this embodiment: A high-pressure emulsifying tank 1, a sealing cap 2, a feed pipe 3, a water pipe 4, a vacuum extraction pipe 5, a double stirring assembly 6, and a wall scraping assembly 7 are installed. During use, the sealing cap 2 is sealed and fixed to the high-pressure emulsifying tank 1. Then, an appropriate amount of boron nitride microparticles are introduced into the high-pressure emulsifying tank 1 through the feed pipe located at the top of the sealing cap 2. The feed pipe 3 is then closed. Next, an appropriate amount of water and additives are injected into the high-pressure emulsifying tank 1 using the water pipe 4. Finally, the vacuum extraction pipe 5 is connected to an external vacuum pump to achieve vacuuming inside the high-pressure emulsifying tank 1.

At the same time, as the dual-stirring component 6 rotates, it also drives the connecting shaft 701 at its bottom to rotate. Then, the rotating connecting shaft 701 drives the bottom scraper 702 and the wall scraper 703 to continuously scrape the bottom and inner wall of the high-pressure emulsification tank 1, respectively.

When the rotating shaft 602 rotates, it will synchronously drive the stirring sleeve 603 on its outer side to perform stirring and emulsification of boron nitride particles, water, and additives in the high-pressure emulsification tank 1. At the same time, while the stirring sleeve 603 is stirring, it will also drive the threaded blade 604 on its outer side to simultaneously mix and emulsify the boron nitride particles, water, and additives. This dual stirring structure improves the efficiency of mixing and emulsification.

[0032] In this embodiment, by setting the support rod 8 and the positioning plate 9, the high-pressure emulsifying tank 1 can be supported to maintain the stability of the high-pressure emulsifying tank 1 during use.

[0033] As a technical optimization of this utility model, through holes 10 are provided on both sides of the top of the positioning disk 9, and positioning bolts 11 are provided inside the through holes 10.

[0034] In this embodiment: by setting through hole 10 and positioning bolt 11, the positioning plate 9 can be fixed to the ground by passing the positioning bolt 11 through the through hole 10 of the positioning plate 9 and fixing it to the ground, thereby improving the strength of the support rod 8 at the bottom of the positioning plate 9 for the high pressure emulsifying tank 1.

[0035] As a technical optimization of this utility model, the bottom of the high-pressure emulsifying tank 1 is connected to a discharge pipe 12, and the front side of the discharge pipe 12 is connected to an electromagnetic liquid control valve 13.

[0036] In this embodiment, by setting up a discharge pipe 12 and an electromagnetic liquid control valve 13, it is possible to facilitate the discharge of the emulsified material inside the high-pressure emulsification tank 1.

[0037] As a technical optimization of this utility model, the front side of both the scraper rod 703 and the stirring sleeve rod 603 is provided with a resistance-reducing and flow-diverting hole 14, which is a circular groove.

[0038] In this embodiment, by setting the resistance-reducing flow-diverting hole 14, the resistance of the scraper rod 703 and the stirring sleeve rod 603 during the stirring process can be reduced, thereby improving the stirring efficiency.

[0039] As a technical optimization of this utility model, an anti-settling stirring column 15 is bolted to the top of the scraper plate 702. The anti-settling stirring column 15 is a long circular column.

[0040] In this embodiment, by setting an anti-sedimentation stirring column 15, the emulsified material at the bottom of the high-pressure emulsification tank 1 can be stirred to avoid sedimentation, thereby increasing practicality.

[0041] As a technical optimization of this utility model, solenoid valves are provided on the front side of both the feed pipe 3 and the water pipe 4, and the solenoid valves are equipped with flow display function.

[0043] Working principle: First, during use, the sealing cap 2 is sealed and fixed to the high-pressure emulsifying tank 1. Then, an appropriate amount of boron nitride particles are introduced into the high-pressure emulsifying tank 1 through the feed pipe located at the top of the sealing cap 2. Then, the feed pipe 3 is closed. Next, an appropriate amount of water and additives are injected into the high-pressure emulsifying tank 1 through the water pipe 4. Finally, the vacuum pipe 5 is connected to an external vacuum pump to achieve vacuuming inside the high-pressure emulsifying tank 1. After all this is completed, the variable frequency motor 601 located at the top of the sealing cap 2 is started, which drives the rotating shaft 602 located inside the high-pressure emulsifying tank 1 to rotate. When the rotating shaft 602 rotates, it synchronously drives the stirring sleeve 603 on its outer side to achieve vacuuming inside the high-pressure emulsifying tank 1. The boron nitride particles, water, and additives are mixed and emulsified. Simultaneously, while the stirring sleeve 603 is agitating, it also drives the threaded blades 604 on its outer side to mix and emulsify the boron nitride particles, water, and additives in a synchronized manner. This dual-stirring structure improves the efficiency of mixing and emulsification. At the same time, as the rotating shaft 602 rotates, it also drives the connecting shaft 701 at its bottom to rotate. The rotating connecting shaft 701 then drives the bottom scraper 702 and the wall scraper 703 to continuously scrape the bottom and inner wall of the high-pressure emulsification tank 1, respectively. This avoids the phenomenon of material sticking and hardening during the long-term stirring of the material emulsification process, thereby avoiding material waste and facilitating subsequent cleaning and use.
