[0002] Silicon nitride is an inorganic compound with the chemical formula Si3N4. It is an important structural ceramic material, characterized by high hardness, inherent lubricity, and wear resistance; it is an atomic crystal. The production of silicon nitride requires mixing high-purity silicon powder and a silicon nitride diluent, necessitating the use of a mixing device.

[0003] Existing mixing devices typically use stirring rods to mix the internal materials when processing silicon nitride. However, due to the gap between the stirring rods and the accumulation of some materials in the discharge pipe at the bottom of the device, the mixing effect is poor, requiring a long mixing time and resulting in low mixing efficiency.

[0004] Therefore, it is necessary to provide a mixing device for silicon nitride production and processing to solve the above-mentioned technical problems. Utility Model Content

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a mixing device for silicon nitride production and processing, such as... Figure 1-3 As shown, the mixing device for silicon nitride production and processing includes: a base plate 1, a support plate 2 fixedly installed on the top of the base plate 1, a support block 3 fixedly installed on the support plate 2, a box 4 fixedly installed on the support block 3, and a discharge pipe 5 fixedly installed at the bottom of the box 4; and a deep mixing mechanism for processing silicon nitride assembled on the support plate 2 and the box 4.

[0022] In this embodiment, when processing silicon nitride, the device pours the materials to be mixed, such as high-purity silicon powder and silicon nitride diluent, into the box 4. After the materials are poured in, the deep mixing mechanism is activated to mix the materials in the box 4. During the mixing process, the multiple stirring racks 13 and spiral blades 15 on the deep mixing mechanism move up and down while rotating. Compared with traditional mixing devices, this can greatly improve the mixing effect, shorten the mixing time, and improve the mixing efficiency. The rotation of the spiral blades 15 can not only stir the materials in the discharge pipe 5, but also transport the materials in the discharge pipe 5 upward, which can further improve the mixing effect.

[0023] In a further preferred embodiment of this utility model, the deep mixing mechanism includes: a top plate 6 fixedly installed on the top of the support plate 2, a plurality of support rods 7 fixedly installed on the top plate 6, the bottom ends of the plurality of support rods 7 being fixedly connected to the top of the housing 4; a plurality of springs 8 respectively slidably sleeved on the plurality of support rods 7; a push plate 9 slidably installed on the plurality of support rods 7, a housing 10 fixedly installed on the push plate 9, a servo motor 11 fixedly installed on the top inner wall of the housing 10; and a rotating shaft 12 rotatably installed on the housing 10, the top end of the rotating shaft 12 being fixedly connected to the output shaft of the servo motor 11, and the rotating shaft 12 slidingly with the housing 4. The shaft 12 is connected to a plurality of stirring racks 13, all of which are located inside the housing 4. A connecting rod 14 is fixedly installed at the bottom end of the shaft 12, and a spiral blade 15 is fixedly sleeved on the connecting rod 14. The spiral blade 15 is located inside the discharge pipe 5. A rotating rod 16 is rotatably installed on the support plate 2. One end of the rotating rod 16 is rotatably connected to one side of the housing 4. A cam 17 is fixedly sleeved on the rotating rod 16 and contacts the push plate 9. A drive motor 18 is fixedly installed on the support plate 2, and the output shaft of the drive motor 18 is fixedly connected to one end of the rotating rod 16.

[0024] In this embodiment, during mixing, the servo motor 11 and drive motor 18 are activated. The servo motor 11 drives the rotating shaft 12 to rotate, which in turn drives the connecting rod 14 and multiple mixing racks 13 to rotate. The connecting rod 14 drives the spiral blades 15 to rotate. Simultaneously, the drive motor 18 drives the cam 17 to rotate via the rotating rod 16. The cam 17 presses against the push plate 9, causing it to slide vertically on multiple support rods 7 and compress multiple springs 8. As the cam 17 continues to rotate, the multiple springs 8 immediately push the push plate 9 back to its original position, thus allowing the drive motor 18 to continue operating. The push plate 9 will move up and down repeatedly, which in turn drives the housing 10 to move up and down. The housing 10 will drive the servo motor 11, the rotating shaft 12, multiple mixing racks 13, the connecting rod 14 and the spiral blades 15 to move up and down, so that the multiple mixing racks 13 and the spiral blades 15 can move up and down while rotating. Compared with traditional mixing devices, this can greatly improve the mixing effect, shorten the mixing time and improve the mixing efficiency. The rotation of the spiral blades 15 can not only stir the material in the discharge pipe 5, but also transport the material in the discharge pipe 5 upward, which can further improve the mixing effect.

[0025] In a further preferred embodiment of the present invention, a hopper 19 is fixedly installed on the top of the box 4, and a cover is threaded onto the hopper 19.

[0026] In this embodiment, the use of the hopper 19 makes it convenient for people to put the materials to be mixed into the box 4. The use of the cover can cover the top of the hopper 19 to prevent impurities from entering the box 4 from the hopper 19.

[0027] In a further preferred embodiment of the present invention, the mixing device for silicon nitride production and processing further includes a blocking mechanism installed on the housing 4 for blocking the discharge pipe 5.

[0028] In this embodiment, the material blocking mechanism can both block and unblock the discharge pipe 5.

[0029] In a further preferred embodiment of this utility model, the material blocking mechanism includes: an electric push rod 20 fixedly installed at the bottom of the box 4, a fixing block 21 fixedly installed on the output rod of the electric push rod 20, a baffle 22 fixedly installed on the fixing block 21, a sealing layer fixedly installed on the baffle 22, and the sealing layer being adapted to the sliding groove on the discharge pipe 5.

[0030] In this embodiment, when the materials are mixed and need to be discharged, the electric push rod 20 is activated. The electric push rod 20 will drive the fixed block 21 to move horizontally, and the fixed block 21 will drive the baffle 22 to move horizontally, so that the sealing layer on the baffle 22 slides on the sliding groove of the discharge pipe 5. When the baffle 22 and the sealing layer move towards the outer wall of the discharge pipe 5, the materials in the box 4 will be discharged from the discharge pipe 5. At the same time as the discharge, the servo motor 11 can be activated to drive the rotating shaft 12 to reverse. The rotating shaft 12 will drive the connecting rod 14 and the spiral blade 15 to reverse. The spiral blade 15 will push the materials to move into the discharge pipe 5, which can help with the discharge and effectively prevent the materials from blocking the discharge pipe 5, making the material discharge smoother.

[0031] In a further preferred embodiment of the present invention, the sealing layer is made of rubber material, and a plurality of heat dissipation holes are provided on one side of the housing 10.

[0032] In this embodiment, the use of multiple heat dissipation holes can help dissipate heat from the servo motor 11.

[0033] In a further preferred embodiment of the present invention, a triangular block is fixedly installed on the top of the base plate 1, and one side of the triangular block is fixedly connected to the support plate 2.

[0034] In this embodiment, the use of triangular blocks can enhance the connection strength between the base plate 1 and the support plate 2.

[0035] In summary, compared with related technologies, this solution, through the use of hopper 19, can feed silicon nitride production materials into the box 4. Through the use of deep mixing mechanism, the materials can be mixed more deeply. Multiple mixing racks 13 and spiral blades 15 can move up and down while rotating, allowing the multiple mixing racks 13 to mix the materials in the box 4 more thoroughly, and the spiral blades 15 to mix the materials in the discharge pipe 5 and convey the materials in the discharge pipe 5 upwards. This can greatly improve the mixing effect, shorten the mixing time, and effectively solve the technical problems of poor mixing effect and low mixing efficiency in existing mixing devices when processing silicon nitride, due to the certain gap between the mixing rods and the accumulation of some materials in the discharge pipe at the bottom of the device.
