Abstract
Description
Technical Field
[0001] This utility model relates to the field of evaporation equipment technology, specifically to a raw material evaporation device for boron nitride preparation. Background Technology
[0002] Boron nitride is an inorganic non-metallic material. In the preparation of boron nitride, it is necessary to evaporate the water in the boron nitride paste raw material through evaporation. In order to ensure that the evaporation plate on which the material is placed is heated evenly during the evaporation process, and to scrape the material during the evaporation process to accelerate the water evaporation efficiency, this utility model proposes a raw material evaporation device for boron nitride preparation. Summary of the Invention
[0003] The purpose of this invention is to provide a raw material evaporation device for boron nitride preparation, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an evaporation device for boron nitride preparation, comprising an evaporation cylinder with an inner cavity. An evaporation plate is rotatably mounted on the inner cavity. Multiple heating rods are positioned below the evaporation plate. The evaporation plate is annular, and an adjustment mechanism is fixedly mounted at its center. A slider is slidably mounted within the adjustment mechanism. Multiple mounting rods are fixedly connected to the outer side of the slider, and scrapers are mounted on the mounting rods. Multiple scraper blades are arranged at the bottom of the scrapers. A rack is arranged around the outer side of the evaporation plate. A gear that meshes with the rack on the outer side of the evaporation plate and a motor for driving the gear are rotatably mounted inside the evaporation cylinder. A top cover with an air vent is provided on the top of the evaporation cylinder. By arranging the heating rods in an evenly spaced annular pattern at the bottom of the inner cavity, the heating resistance wires inside the heating rods are energized and heated. The motor and gear drive the evaporation plate to rotate at a uniform speed, ensuring uniform heating of the bottom of the evaporation plate. The scrapers agitate the material on the evaporation plate during rotation, improving the evaporation effect.
[0005] Preferably, an annular limiting groove is formed at the bottom of the inner cavity, and a limiting wheel is rotatably provided at the bottom of the evaporating plate, the limiting wheel being slidably disposed within the limiting groove. By providing a wheel-shaped structure, the frictional force that the evaporating plate needs to overcome when rotating can be reduced.
[0006] Preferably, the adjusting mechanism is screwed with an adjusting screw, one end of which contacts the bottom of the slider, and the other end extends out of the bottom of the evaporator and is screwed with a locking nut. By rotating the adjusting nut, the height of the adjusting slider is increased, thereby adjusting the distance between the bottom scraper of the scraper and the top of the evaporator plate.
[0007] Preferably, the mounting rod has multiple elongated mounting holes, and the scraper has multiple studs that can pass through the mounting holes, with nuts screwed onto the studs. The elongated mounting holes allow for easy adjustment of the scraper's position in the horizontal direction of the mounting rod, ensuring that the movement trajectories of the scraper blades at the bottom of each scraper do not overlap.
[0008] Compared with the prior art, the beneficial effects of this utility model are: the rotating design of the evaporation plate allows the evaporation plate to be heated evenly, and the adjustable scraper design facilitates the stirring of the material on the evaporation plate, thereby improving the material moisture evaporation efficiency.

[0013] Referring to Figures (1-2), an evaporation apparatus for preparing boron nitride raw materials includes an evaporation cylinder 1. An inner cavity 11 is formed inside the evaporation cylinder 1. An evaporation plate 2 is rotatably mounted on the inner cavity 11. Multiple heating rods 12 are positioned below the evaporation plate 2. The evaporation plate 2 is annular, and an adjustment mechanism 3 is fixedly mounted at its center. A slider 31 is slidably mounted inside the adjustment mechanism 3. Multiple mounting rods 32 are fixedly connected to the outside of the slider 31. Scrapers 4 are mounted on the mounting rods 32. Multiple scraper strips 41 are arranged at the bottom of the scrapers 4. A ring of toothed teeth is arranged on the outside of the evaporation plate 2. A gear that meshes with the outer rack of the evaporation plate 2 and a motor for driving the gear are rotatably mounted inside the evaporation cylinder 1. A top cover 14 is provided on the top of the evaporation cylinder 2, and an air vent is provided on the top cover.
[0014] The bottom of the inner cavity 11 is provided with an annular limiting groove 13, and the bottom of the evaporation plate 2 is provided with a limiting wheel 21, which is slidably disposed in the limiting groove 13. An adjusting screw 35 is screwed onto the adjusting mechanism 3. One end of the adjusting screw 35 contacts the bottom of the slider 31, and the other end passes through the bottom of the evaporation cylinder 1 and is screwed with a locking nut. The mounting rod 32 is provided with multiple elongated mounting holes 33, and the scraper 4 is provided with multiple studs 42 that can pass through the mounting holes 33, and nuts are screwed onto the studs 42.
[0015] When using this device, the material is spread evenly on the top of the evaporation pan 2, and electricity is supplied to the heating resistance wire in the heating rod 12 to heat the evaporation pan 2. The motor drives the gear to rotate the evaporation pan 2, so that the bottom of the evaporation pan 2 is heated evenly. At the same time, the scraper 4 is installed on the mounting rod 32. By rotating the adjusting screw 35, the adjusting screw 35 pushes the slider 31 and the mounting rod 32 and scraper 4 connected to the slider upward to move upward, or the adjusting screw 35 moves downward to move the slider 31 downward under its own weight and the elastic force of the spring 34, so as to adjust the distance between the bottom of the scraper 4 and the top of the evaporation pan 2.
