Description

[0002] As an important inorganic non-metallic material, boron nitride has a wide range of applications in many fields due to its excellent physical and chemical properties. In the preparation process of boron nitride, an evaporation device is needed to evaporate the water vapor in the boron nitride paste raw material to obtain dry boron nitride.

[0003] When the existing evaporation device for boron nitride paste raw materials is in use, the boron nitride paste raw material is only filled in the evaporation tray, and then the evaporation tray containing the boron nitride paste raw material is placed inside the evaporation device for evaporation and drying. Although the purpose of evaporation and drying is achieved in this way, the evaporation process is carried out in a static manner, resulting in a relatively slow evaporation efficiency. Therefore, we propose an evaporation device for boron nitride paste raw materials to solve the above problems. Content of the Utility Model

[0029] Specifically, when in use, pull the handle 3 to open the box door 2, then add the boron nitride paste raw material to be evaporated into the evaporation pan 9. Then, the heating plate 6 works, and at this time, the inside of the evaporation box 1 can be heated, so that the boron nitride paste raw material in the evaporation pan 9 can be evaporated. When evaporating the boron nitride paste raw material, the power mechanism 4 works, and at this time, power can be provided to the stirring assembly 8. Then, with the cooperation of the stirring assembly 8, the boron nitride paste raw material in the evaporation pan 9 can be stirred, which is beneficial to the steam at the bottom of the evaporation pan 9 to dissipate outward, thereby accelerating the evaporation of the boron nitride paste raw material and improving the production efficiency of boron nitride. When it is necessary to discharge the evaporated boron nitride raw material after evaporation, the scraping assembly 7 can be used to scrape off the boron nitride raw material in the evaporation pan 9, so that when discharging the boron nitride raw material, it is not necessary for workers to manually clean the boron nitride raw material in the evaporation pan 9, thereby reducing the labor intensity of workers.

[0030] The power mechanism 4 includes a motor 401, a rotating shaft 402, a first gear 403, and a second gear 404. The rotating shaft 402 is rotatably connected to the inside of the rear end of the evaporation box 1, and the circumferential surface of the rotating shaft 402 is fixedly connected with the first gear 403. The circumferential surface of the support column 10 is rotatably connected with the second gear 404, and the second gear 404 meshes with the first gear 403. There are two first gears 403 and two second gears 404. When working, the motor 401 works, and at this time, the first gear 403 can be driven with the cooperation of the rotating shaft 402, and then the second gear 404 can be driven to rotate, so as to provide power for the stirring assembly 8.

The lower end of the support plate 802 is fixedly connected with the stirring rod 803, and the stirring rod 803 is located inside the evaporation pan 9. When working, as the second gear 404 rotates, the frame 801 can be driven to rotate, and then the stirring rod 803 can be driven to rotate with the cooperation of the support plate 802. As the stirring rod 803 rotates, the boron nitride paste raw material in the evaporation pan 9 can be stirred, which is beneficial to the steam at the bottom of the evaporation pan 9 to dissipate outward, thereby accelerating the evaporation of the boron nitride paste raw material and improving the production efficiency of boron nitride.

The lower end of the moving plate 705 is fixedly connected with the scraper 706. Both the moving plate 705 and the scraper 706 are slidably connected with the stirring rod 803. During operation, when it is necessary to discharge the evaporated boron nitride raw material, rotate the first handle 703. At this time, with the cooperation of the lead screw 702, the slider 704 can be driven to move, and then the moving plate 705 can be driven to move. When the moving plate 705 moves downward, the scraper 706 can be driven to extend into the evaporation pan 9. After the scraper 706 extends into the evaporation pan 9, the boron nitride raw material inside the evaporation pan 9 can be scraped off as the scraper 706 rotates. The scraped boron nitride raw material is convenient for subsequent discharge, so that when discharging the boron nitride raw material, it is not necessary to manually clean the boron nitride raw material inside the evaporation pan 9, thereby reducing the labor intensity of workers.
