[0003] In existing technologies, aluminum hydroxide samples are typically placed on a rack in a furnace. The heating temperature and heating rate are set by a temperature control system. The heating element is energized and heats up, raising the temperature inside the furnace to perform heat treatment on the aluminum hydroxide.

[0004] However, when the rack is placed inside the furnace, it remains relatively stationary, which makes the position of the aluminum hydroxide material relatively fixed during the heat treatment process. This results in different degrees of contact between different parts of the material and the heat source. The material near the heating element or furnace wall is prone to overheating, while the material inside or far from the heat source is underheated, leading to local overheating or undercooling, which in turn affects the quality and performance of the product.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] Please see Figures 1 to 2 This utility model provides a technical solution: a heat treatment device for aluminum hydroxide, including a heating furnace 1, a furnace chamber 19 on the surface of the heating furnace 1, a shaft 6 rotatably connected to the surface of the heating furnace 1, a support rod 3 inserted into the surface of the shaft 6, two elastic buckles 16 fixedly connected to the surface of the support rod 3, the elastic buckles 16 being embedded in the surface of the shaft 6, multiple sets of adjusting blocks 7 inserted into the surface of the support rod 3, and two shelves 4 mounted on the surface of the support rod 3, with the adjusting blocks 7 attached to the bottom end of the shelves 4;

[0025] Through the cooperation of motor 5, shaft 6 and support rod 3, the shelf 4 can rotate, thereby enabling aluminum hydroxide to be heated more evenly during heat treatment and improving product performance.

[0026] By adjusting the block 7 within the adjusting groove 10, and in conjunction with the spring 12 and guide rod 11, the height of the shelf 4 can be easily adjusted to meet the placement requirements of aluminum hydroxide for different batches and processing needs, thus improving the applicability of the device.

[0027] Example 2

[0028] Please see Figures 1 to 4 Based on Embodiment 1, in order to install the support rod 3, a heating plate 2 is provided on the surface of the heating furnace 1. By passing current through the resistance wire in the heating plate 2, electrical energy is converted into heat energy, thereby heating the furnace chamber 19. A motor 5 is provided inside the heating furnace 1. One end of the shaft 6 is connected to the output end of the motor 5, and the other end of the shaft 6 extends through to the surface of the furnace chamber 19.

[0029] The shaft 6 has a T-shaped cylindrical structure. A limiting groove 17 is provided on the surface of the end of the shaft 6 away from the motor 5. A buckle groove 15 is provided on the surface of the shaft 6. An elastic buckle plate 16 is fastened in the buckle groove 15. The elastic buckle plate 16 has an L-shaped plate structure and one end of the elastic buckle plate 16 is provided with a bevel. Utilizing the guiding effect of the bevel and its own elasticity, it can automatically snap into the buckle groove 15 on the surface of the shaft 6, and firmly fix the support rod 3 to the shaft 6.

[0030] The bottom end of the support rod 3 is fixedly connected to a limiting block 8. The limiting block 8 has a cross-shaped plate structure and is inserted into the surface of the limiting groove 17. Through the cross-shaped structure, the limiting block 8 is embedded in the limiting groove 17, thereby causing the shaft 6 to drive the support rod 3 to rotate synchronously. The surface of the support rod 3 has two sliding grooves 18. The sliding grooves 18 are rectangular grooves. Two sets of sliding blocks 14 are slidably connected to the surface of the sliding grooves 18. By setting the sliding grooves 18 and the sliding blocks 14, the fixed ring 13 and the support rod 3 maintain a relatively stable rotation, while facilitating the horizontal adjustment of the shelf 4.

[0031] Example 3

[0032] Please see Figures 1 to 5 Based on Embodiment 2, in order to adjust the height of the shelf 4, there are two sliding blocks 14. Each set of sliding blocks 14 has a fixed ring 13 fixedly connected to its surface. The shelf 4 is fixedly connected to the surface of the fixed ring 13. The shelf 4 is made of high temperature resistant metal mesh, and the mesh diameter can ensure that the hot airflow passes through evenly.

[0033] The surface of the support rod 3 has multiple sets of adjustment grooves 10, with two in each set. The adjustment block 7 is slidably connected to the surface of the adjustment groove 10. The adjustment groove 10 provides a sliding track for the adjustment block 7. One end of the adjustment block 7 is provided with an arc surface. When the fixing ring 13 moves upward, pressure can be applied to the adjustment block 7 along the arc surface of the adjustment block 7, thereby causing the adjustment block 7 to extend and retract, which facilitates the adjustment of the position of the fixing ring 13 and the shelf 4.

[0034] One end of the adjusting groove 10 has a guide groove 9, which is a T-shaped circular groove. A guide rod 11 is inserted into the surface of the guide groove 9, which is a T-shaped circular plate structure.

[0035] A spring 12 is fitted onto the surface of the guide rod 11. The spring 12 is made of high carbon steel and provides sufficient elastic force to fix the adjusting block 7. One end of the guide rod 11 is fixedly connected to the surface of the adjusting block 7. When the adjusting block 7 moves into the adjusting groove 10, the spring 12 will be compressed to provide elastic force. After the adjusting block 7 stops moving, the elastic force of the spring 12 can keep the adjusting block 7 in the current position, thus fixing the adjusting block 7.

[0036] In actual use, firstly, align the limiting block 8 at the bottom of the support rod 3 with the limiting groove 17 on the shaft 6 and insert it. During the insertion process, the elastic buckle 16 on the surface of the support rod 3 undergoes elastic deformation due to the pressure of the shaft 6 surface on one end of the inclined surface. When the limiting block 8 is fully inserted into the limiting groove 17, the elastic buckle 16 recovers its deformation under its own elastic force and springs into the buckle groove 15 on the surface of the shaft 6, thereby firmly fixing the support rod 3 to the shaft 6. Then, place the container containing aluminum hydroxide on the shelf 4, start the heating plate 2 on the surface of the heating furnace 1 to heat the furnace chamber 19, and at the same time, start the motor 5. The output shaft of the motor 5 drives the shaft 6 to rotate, and the shaft 6 in turn drives the support rod 3 and the shelf 4 fixed on it to rotate. During the rotation process, the aluminum hydroxide is heated evenly in all directions in the furnace chamber 19, ensuring the heat treatment effect and the stability of product quality.

[0037] When the shelf 4 needs to be adjusted downwards along the support rod 3, with the shelf 4 in an unloaded state, first press the set of adjusting blocks 7 that are in contact with the fixing ring 13 towards the opposite end, so that the adjusting blocks 7 overcome the elastic force of the spring 12 and drive the guide rod 11 to slide in the guide groove 9, so that the adjusting blocks 7 are completely retracted in the adjusting groove 10. Then, after adjusting the adjusting blocks 7 to the required height, release the adjusting blocks 7, the spring 12 returns to its original position, push the adjusting blocks 7 to fix them, so that the adjusting blocks 7 fit against the bottom of the shelf 4, realizing convenient adjustment of the height of the shelf 4. When the shelf 4 needs to be adjusted upwards along the support rod 3, the fixing ring 13 squeezes along one end of the arc surface of the adjusting block 7, so that the adjusting blocks 7 overcome the elastic force of the spring 12 and retract in the adjusting groove 10. The upward adjustment can be realized without manually pressing the adjusting blocks 7.

[0038] When disassembling the support rod 3, press the elastic buckle plate 16 to disengage it from the buckle groove 15, and at the same time pull out the limiting block 8 from the limiting groove 17. The support rod 3 can then be removed from the shaft rod 6. The operation is simple and quick, and it is convenient for the device to be maintained or for parts to be replaced.

[0039] 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.
