Description

Technical Field

[0001] This utility model relates to the field of drying equipment, and in particular to a dryer for transparent aluminum oxynitride ceramic semi-finished products. Background Technology

[0002] Alumina oxynitride transparent ceramic is a type of special ceramic, a polycrystalline ceramic material with excellent optical, physical, and chemical properties. It is synthesized from aluminum oxide and nitrogen and has the advantages of high transparency, high hardness, high strength, high temperature resistance, and wide application. In the preparation process, a dryer is needed to dry the semi-finished product after molding. Existing dryers are prone to uneven drying during the drying process, which can cause the alumina oxynitride transparent ceramic semi-finished product to crack. Therefore, it is particularly necessary to design a dryer for alumina oxynitride transparent ceramic semi-finished product that can dry evenly and reduce cracking caused by uneven drying. Summary of the Invention

[0003] The purpose of this invention is to provide a dryer for transparent aluminum oxynitride ceramic semi-finished products, which has the advantage of uniform drying and reduces cracking caused by uneven drying.

[0004] The technical solution adopted is as follows:

[0005] A semi-finished aluminum oxynitride transparent ceramic dryer includes an insulated box with multiple heating units on its inner wall. A support tube is vertically rotatably installed inside the insulated box, with its upper end extending to the outside of the insulated box. A drive shaft is coaxially rotatably installed inside the support tube. Multiple dehumidification holes are opened on the support tube inside the insulated box. A drive mechanism connected to both the support tube and the drive shaft is installed at the upper end of the insulated box. Multiple support boxes are arranged from top to bottom on the side of the support tube. Multiple discs are rotatably installed at the upper end of the support boxes. The lower end of each disc inside the support box is connected to a driven gear. The drive shaft is equipped with a drive gear meshing with the driven gear.

[0006] Preferably, the heating unit is an electric heating tube.

[0007] Preferably, the driving mechanism includes a drive motor, the drive motor includes an output shaft, the output shaft extends vertically and is provided with a first gear and a first sprocket from bottom to top, a second gear meshing with the first gear is provided on the support tube, a second sprocket is provided at the upper end of the drive shaft, and a chain is provided between the first sprocket and the second sprocket.

[0008] Preferably, the drive motor is a variable frequency speed control motor.

[0009] Preferably, there are six disks.

[0010] Compared to existing technologies, the advantages are:

[0011] This invention utilizes a drive mechanism to drive the support tube and drive shaft to rotate. The support tube drives each support box to rotate, and the drive shaft drives each disc to rotate. The discs are used to place the alumina oxynitride transparent ceramic semi-finished product. This allows the alumina oxynitride transparent ceramic semi-finished product to rotate in the center of the heat preservation box while also rotating itself, ensuring uniform contact with the heating unit and uniform heating, thus reducing cracking caused by uneven heating.

The support tube 4 inside the insulation box 1 has multiple dehumidification holes 7, which facilitate the entry of humid air from the insulation box 1 into the support tube 4 and its discharge from the upper end of the support tube 4.

[0020] The upper end of the insulation box 1 is provided with a drive mechanism that is connected to both the support tube 4 and the drive shaft 5. The drive mechanism drives the drive shaft 5 and the support tube 4 to rotate. Multiple support boxes 15 are provided on the side of the support tube 4 from top to bottom. The multiple support boxes 15 divide the support tube 4 into multiple parts connected end to end. Multiple discs 16 are rotatably provided on the upper end of the support box 15. Each disc 16 is coaxially provided with a rotating shaft 17 extending into the support box 15. The lower end of each disc 16 inside the support box 15 is connected to a driven gear 18. Each driven gear 18 is fixedly connected to the corresponding rotating shaft 17. The drive shaft 5 is provided with a drive gear 19 that meshes with the driven gear 18.

[0021] The support tube 4 drives each support box 15 to rotate, and the drive shaft 5 drives each disc 16 to rotate. The disc 16 is used to place the aluminum oxynitride transparent ceramic semi-finished product, so that the aluminum oxynitride transparent ceramic semi-finished product rotates in the center of the heat preservation box 1 while also rotating itself, making uniform contact with the heating unit 2 and receiving uniform heating.

[0022] Example 2: A semi-finished dryer for transparent aluminum oxynitride ceramics includes an insulated box 1. The inner wall of the insulated box 1 is provided with multiple heating units 2.
