[0030] See also Figures 1 to 4 As shown, this embodiment is a pretreatment device for high-performance silicon nitride materials, comprising:

[0031] A stirring tank 11, a sealing cover 12 is fixed to the upper surface of the stirring tank 11, and a rotating shaft 25 passes through the sealing cover 12;

[0032] The mixing tank 11 is used to contain the raw materials to be mixed, ensuring that the raw materials can be fully mixed during the mixing process. At the same time, the sealing cover 12 can prevent the materials from splashing out or polluting the environment during the mixing process.

[0033] The adjusting assembly includes a rotating shaft 25, a stirring fan 26, a mounting groove 27, a spring 28, a connecting block 29, a connecting groove 291, a through hole 292, a connecting shaft 293, and a pressing roller 294. The rotating shaft 25 is rotatably installed inside the stirring tank 11, the stirring fan 26 is fixed on the outer surface of the rotating shaft 25, the mounting groove 27 is arranged on the lower surface of the stirring fan 26, the spring 28 is fixed inside the mounting groove 27, the connecting block 29 is fixed on the lower end of the spring 28, the connecting groove 291 is arranged on the lower surface of the connecting block 29, the through hole 292 is arranged on both sides of the outer surface of the connecting block 29, the connecting shaft 293 is rotatably penetrated in the through hole 292, and the pressing roller 294 is rotatably penetrated on the outer surface of the connecting shaft 293;

[0034] The rotating shaft 25 connects the motor 24 and the stirring fan 26, and transmits the rotational motion generated by the motor 24 to the stirring fan 26, so as to achieve stirring of the material. The stirring fan 26 is fixed on the rotating shaft 25, and rotates driven by the rotating shaft 25 to achieve stirring of the material. The stirring fan 26 ensures that the material can be fully mixed. The connecting block 29 is an intermediate component connecting the spring 28 and the pressure roller 294, and is connected to the stirring fan 26 through the spring 28. The pressure roller 294 rotates and passes through the outer surface of the connecting shaft 293, and contacts with the inner bottom surface of the stirring tank 11. When the electric push rod 22 pushes the rotating shaft 25 to move downward, the contact gap between the pressure roller 294 and the bottom of the stirring tank 11 becomes smaller, which makes it easier to crush large particles of raw materials and improve the uniformity of stirring.

[0035] A motor 24 is fixed to the upper end of the rotating shaft 25, a fixing plate 23 is fixed to the outer surface of the motor 24, and electric push rods 22 are fixed to both sides of the lower surface of the fixing plate 23, a side connecting plate 21 is fixed to the lower surface of the electric push rod 22, and the outer surface of the mixing tank 11 is fixed to one side of the side connecting plate 21, and the lower surface of the pressure roller 294 contacts the inner bottom surface of the mixing tank 11;

[0036] The fixing plate 23 is used to fix the motor 24 and connect the motor 24 to the electric push rod 22, thereby ensuring the stability and reliability of the motor 24. The side connecting plate 21 is used to connect the electric push rod 22 and the mixing tank 11, and fix the electric push rod 22 on the outer surface of the mixing tank 11, thereby ensuring the stability and reliability of the entire system.

[0037] Working principle:

[0038] When the silicon nitride is stirred, a variety of raw materials are added. When some large particles of raw materials are deposited at the bottom of the stirring tank 11, the staff controls the electric push rod 22 and the motor 24 through the external controller. The motor 24 drives the rotating shaft 25 to rotate, and the rotating shaft 25 synchronously drives the stirring fan 26 to rotate, and the stirring fan 26 synchronously drives the spring 28 to rotate, and the spring 28 synchronously drives the connecting block 29 to rotate, and the connecting block 29 synchronously drives the pressing roller 294 to rotate. The controller controls the electric push rod 22 to extend and retract, and drives the rotating shaft 25 to move downward, so that the contact gap between the pressing roller 294 and the bottom of the stirring tank 11 becomes smaller, which makes it easier to crush the large particles of raw materials and improves the uniformity of stirring.

[0039] In this step, the electric push rod 22 and the motor 24 work together to enable the stirring fan 26 and the pressure roller 294 to act more effectively on the large-particle raw materials, crush them and mix them with other raw materials, thereby improving the stirring efficiency.

[0040] See also Figures 1 to 4 As shown; this embodiment is based on the above embodiment and also includes:

[0041] A stirring assembly, the stirring assembly includes a rotating groove 31 and a rotating column 32. The rotating groove 31 is opened inside the stirring fan 26. The rotating column 32 rotates through the rotating groove 31. The outer surface of the rotating column 32 rotates through the rotating fan 33.

[0042] The rotating groove 31 is opened inside the stirring fan 26, and is designed to accommodate the rotating column 32. The rotation of the rotating fan 33 also helps to break up the agglomeration between the materials, so that the stirring is more thorough.

[0043] Working principle:

[0044] When stirring silicon nitride, the staff controls the motor 24 to rotate, the motor 24 drives the rotating shaft 25 to rotate, the rotating shaft 25 rotates synchronously to drive the stirring fan 26 to rotate, the stirring fan 26 rotates, and the rotating fan 33 is synchronously driven to rotate under the rotation of the silicon nitride raw material, and the rotating fan 33 drives the rotating column 32 to rotate, and the rotating fan 33 rotates during the rotation of the stirring fan 26, further driving the mixing of the silicon nitride powder;

[0045] In this step, the dual rotation of the stirring fan 26 and the rotating fan 33 can more effectively break up the agglomeration between the materials, so that the silicon nitride powder and other raw materials are more evenly mixed.
