[0002] Aluminum nitride is a ceramic insulator, which gives it a high heat transfer capacity, causing it to be widely used in microelectronics. Aluminum nitride reacts slowly with water at room temperature, so aluminum nitride is usually sealed and placed under a dry protective gas. The commonly used dry protective gas is nitrogen. Due to the large output of aluminum nitride, storage silos are required for storage and turnover.

[0003] In the prior art, when used, aluminum nitride powder is placed in a reactor, and nitrogen is pumped into the reactor using an air pump, so that the nitrogen and the aluminum nitride powder are contacted and reacted in the reactor to form aluminum nitride, making the storage of the aluminum nitride powder more stable.

[0004] However, in actual use, nitrogen needs to be added to the silo to protect the aluminum nitride powder during storage. However, since the aluminum nitride powder accumulates in the silo, the nitrogen floats on the top of the silo after entering the silo and contacts the aluminum nitride powder on the surface, causing the aluminum nitride powder at the bottom of the silo to not contact the nitrogen, resulting in instability during storage. Utility Model Content

However, since the aluminum nitride powder is accumulated in the silo, the nitrogen floats on the top of the silo after entering the silo and contacts the aluminum nitride powder on the surface, causing the aluminum nitride powder at the bottom of the silo to not contact the nitrogen, resulting in instability during storage.

[0006] To achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: an aluminum nitride powder storage silo, including a silo, a feed pipe is installed on the top of the silo, a discharge pipe is connected to the bottom of the silo, a valve is installed at one end of the discharge pipe, vibrators are installed on both sides of the outer wall of the discharge pipe, a bracket is installed on the outer wall of the silo, a nitrogen filling nozzle is installed at the bottom of the silo, a flip structure is installed inside the silo, the flip structure includes a servo motor, a drive rod and a stirring blade, the outer wall of the servo motor is fixedly connected to the outer wall of the silo, the output end of the servo motor extends to one end of the silo fixedly connected to the drive rod, the outer wall of the drive rod is rotatably connected to the inner wall of the silo through a bearing, and the outer wall of the drive rod is fixedly connected to the stirring blade.

[0007] Preferably, a sealing cover is installed on the top of the feed pipe, and the outer wall of the feed pipe is connected to a pressure gauge.

[0008] Preferably, a vacuum exhaust pipe is connected to one side of the top of the silo.

[0009] Preferably, the inner wall of the feed pipe is rotatably connected to a baffle, the bottom of the baffle is fixedly connected to a torsion spring, and the outer wall of the torsion spring is fixedly connected to the inner wall of the feed pipe.

[0010] Preferably, a connection box is fixedly connected to the bottom of the silo, an outer wall of the connection box is connected to a nitrogen filling nozzle, and an outer wall of the connection box is connected to a connection pipe.

[0011] The utility model has the following beneficial effects: the aluminum nitride powder storage silo is equipped with a servo motor, a driving rod and a stirring blade, and after the aluminum nitride powder is placed in the silo, nitrogen is added to the interior of the silo. After the filling is completed, the servo motor is used to drive the driving rod to rotate, and the stirring blade is used to stir the aluminum nitride powder, so that the aluminum nitride powder inside the silo is in contact with the nitrogen, making it more stable during storage, and solving the problem of the prior art that the nitrogen cannot contact the aluminum nitride powder at the bottom of the silo during use, resulting in unstable storage.

[0012] Through the cooperation of the torsion spring, the baffle and the connecting pipe, when the baffle powder enters the silo through the feed pipe, it will squeeze the baffle, causing the baffle to squeeze the torsion spring to open the feed pipe, and after feeding, under the action of the torsion spring, the baffle will close the feed pipe, which can better seal the silo.
