Technical Field

[0001] The invention relates to the field of mixing equipment for producing high-purity gallium oxide powder, in particular to mixing equipment for producing high-purity gallium oxide powder and a mixing method thereof. Background Art

[0002] The main function of high-purity gallium oxide is to serve as a fourth-generation semiconductor material for the manufacture of power devices and radio frequency devices. As an ultra-wide bandgap semiconductor material, gallium oxide has the characteristics of heat resistance, high efficiency, low cost and a wide range of applications.

[0003] The current mixing equipment for the production of high-purity gallium oxide powder produces high-purity gallium oxide powder by pouring the materials into a mixing barrel for stirring and heating the materials through a heating component. Different batches of materials are different during the grinding process. If they are used directly without mixing, it will affect the next processing procedure. The existing mixing equipment cannot fully mix different batches of raw materials, affecting its use. Summary of the invention

[0004] The purpose of the present invention is to provide a mixing device and a mixing method for producing high-purity gallium oxide powder in order to solve the problem that the existing mixing equipment cannot fully mix raw materials from different batches, thus affecting its use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mixing device for producing high-purity gallium oxide powder and a mixing method thereof, comprising a mixing barrel, a first ring is fixedly connected to the bottom of the mixing barrel, a motor is installed below the mixing barrel, a turntable is fixedly connected to the output end of the motor, a first stirring blade is rotatably connected to the top of the turntable, a first gear is fixedly connected to the bottom of the first stirring blade, the outer surface of the first ring is provided with a first tooth meshing with the first gear, a second stirring blade is rotatably connected to the top of the turntable, and the upper surface of the second stirring blade is fixedly connected to the upper surface of the turntable. A No. 2 gear is fixedly connected to the side, a No. 2 ring is fixedly connected to the upper part of the interior of the mixing barrel, and a No. 2 tooth is provided on the inner surface of the No. 2 ring which meshes with the No. 2 gear. The starting motor drives the turntable to rotate, and the turntable drives the No. 1 stirring blade and the No. 2 stirring blade to rotate. When the No. 1 stirring blade rotates with the turntable, the No. 1 gear meshes with the No. 1 tooth to make the No. 1 stirring blade rotate. When the No. 2 stirring blade rotates with the turntable, the No. 2 gear meshes with the No. 2 tooth to make the No. 2 stirring blade rotate. The rotation direction of the No. 2 stirring blade is opposite to that of the No. 1 stirring blade, which can increase the stirring efficiency and enhance the mixing effect.

[0006] As a further solution of the present invention: a reciprocating screw is fixedly connected to the top of the turntable, and a lifting block is slidably connected to the outer surface of the reciprocating screw, and a limiting rod is fixedly connected to the bottom of the No. 2 ring. A limiting groove that cooperates with the limiting rod is opened above the lifting block. When the turntable rotates, it will drive the reciprocating screw to rotate. The rotation of the reciprocating screw causes the lifting block to slide back and forth along the outer surface of the reciprocating screw, so that the material under the mixing barrel can be pushed to the top of the mixing barrel. Since the outer surface of the lifting block has a certain curvature, the lifting block pushes the material in the middle of the mixing barrel to the edge position inside the mixing barrel when moving, which can increase the mixing efficiency.

[0007] As a further solution of the present invention: first, pour the first batch of materials into the mixing barrel through the feed port, pour the second batch of materials into the storage box, start the motor to drive the turntable to rotate, and the turntable drives the No. 1 stirring blade and the No. 2 stirring blade to rotate. When the No. 1 stirring blade rotates with the turntable, the No. 1 gear and the No. 1 tooth engage with each other, so that the No. 1 stirring blade rotates. When the No. 2 stirring blade rotates with the turntable, the No. 2 gear and the No. 2 tooth engage with each other, so that the No. 2 stirring blade rotates, and the rotation direction of the No. 2 stirring blade is opposite to that of the No. 1 stirring blade, which can increase the stirring efficiency and enhance the mixing effect.

[0008] As a further solution of the present invention: when the turntable rotates, it will drive the reciprocating screw to rotate, and the rotation of the reciprocating screw will cause the lifting block to slide back and forth along the outer surface of the reciprocating screw, so that the material under the mixing barrel can be pushed to the top of the mixing barrel. Since the outer surface of the lifting block has a certain curvature, the lifting block will push the material in the middle of the mixing barrel to the edge position inside the mixing barrel when moving, which can increase the mixing efficiency.

[0009] As a further solution of the present invention: when the lifting block slides upward with the rotation of the reciprocating screw, the fixed plate extends out from the groove, the No. 3 tooth engages with the No. 3 gear, and the No. 3 gear rotates to cause the baffle to slide inside the storage box, thereby opening the storage box, so that the second batch of materials can be automatically poured into the interior of the mixing barrel in batches, thereby improving the mixing efficiency.

[0010] As a further solution of the present invention: when the lifting block slides up and down, the protrusion inside the rotating frame cooperates with the slide groove opened on the outer surface of the reciprocating screw to rotate the No. 4 stirring blade, further enhancing the mixing effect, and can push the material in the middle to both sides without affecting the lifting of the lifting block.

[0011] As a further solution of the present invention: when the reciprocating screw rotates, it will drive the No. 3 stirring blade to rotate, so as to stir the material in the storage box. When the turntable rotates, it can drive the scraper to rotate. The scraper can scrape off the material attached to the inner wall of the mixing barrel, thereby reducing material waste and enhancing the stirring effect.

When the lifting block slides upward with the rotation of the reciprocating screw, the fixed plate extends out of the groove, and the No. 3 tooth meshes with the No. 3 gear. The rotation of the gear causes the baffle to slide inside the storage box, thereby opening the storage box, so that the second batch of materials can be automatically poured into the interior of the mixing barrel in batches, thereby improving the mixing efficiency.

[0013] As a further solution of the present invention: a rotating frame is rotatably connected to the top of the lifting block, and a No. 4 stirring blade is fixedly connected to one side of the rotating frame. The rotating frame is slidably connected to the outer surface of the reciprocating screw, and a protrusion that cooperates with the sliding groove on the surface of the reciprocating screw is arranged inside the rotating frame. When the lifting block slides up and down, the protrusion inside the rotating frame cooperates with the sliding groove provided on the outer surface of the reciprocating screw to make the No. 4 stirring blade rotate, further enhancing the mixing effect, and can push the material in the middle to both sides without affecting the lifting of the lifting block.

[0035] Please refer to Figure 6 A rotating frame 25 is rotatably connected to the top of the lifting block 27, and a No. 4 stirring blade 26 is fixedly connected to one side of the rotating frame 25. The rotating frame 25 is slidably connected to the outer surface of the reciprocating screw 15, and a protrusion that cooperates with the slide groove on the surface of the reciprocating screw 15 is arranged inside the rotating frame 25. When the lifting block 27 slides up and down, the protrusion inside the rotating frame 25 cooperates with the slide groove provided on the outer surface of the reciprocating screw 15 to make the No. 4 stirring blade 26 rotate, further enhancing the mixing effect, and can push the material in the middle to both sides without affecting the lifting of the lifting block 27.

[0036] Please refer to Figures 1 to 4 A connecting rod 24 is fixedly connected to the top of the reciprocating screw 15, and a No. 3 stirring blade 16 is fixedly connected to the top of the connecting rod 24. The No. 3 stirring blade 16 is located inside the storage box 5.

[0037] Please refer to Figures 1 to 4 A feed port 4 is provided above the barrel cover 3, and the first batch of materials is poured into the mixing barrel 1 through the feed port 4. A discharge port 8 is provided below the mixing barrel 1, and a valve is provided inside the discharge port 8.

[0038] The working principle of the above device is:

[0039] When in use, firstly, the first batch of materials is poured into the mixing barrel 1 through the feed port 4, and the second batch of materials is poured into the storage box 5, and the motor 10 is started to drive the turntable 11 to rotate, and the turntable 11 drives the first stirring blade 13 and the second stirring blade 14 to rotate. When the first stirring blade 13 rotates with the turntable 11, the first gear 20 and the first tooth 18 are meshed with each other, so that the first stirring blade 13 rotates, and when the second stirring blade 14 rotates with the turntable 11, the second gear 23 and the second tooth 22 are meshed with each other. , so that the second stirring blade 14 rotates, and the second stirring blade 14 rotates in the opposite direction to the first stirring blade 13, which can increase the stirring efficiency and enhance the mixing effect. When the turntable 11 rotates, it will drive the reciprocating screw rod 15 to rotate. The rotation of the reciprocating screw rod 15 causes the lifting block 27 to slide back and forth along the outer surface of the reciprocating screw rod 15, and the material under the mixing barrel 1 can be pushed to the top of the mixing barrel 1. Because the outer surface of the lifting block 27 has a certain curvature, the lifting block 27 pushes the material in the middle of the mixing barrel 1 to the mixing barrel when it moves. The edge position inside the barrel 1 can increase the stirring efficiency. When the lifting block 27 slides upward with the rotation of the reciprocating screw 15, the fixed plate 28 extends from the groove 6, and the No. 3 tooth 29 is meshed with the No. 3 gear 31. The No. 3 gear 31 rotates to make the baffle 7 slide inside the storage box 5, thereby opening the storage box 5, so that the second batch of materials can be automatically poured into the mixing barrel 1 in batches, thereby improving the stirring efficiency. When the lifting block 27 slides up and down, the protrusion inside the rotating frame 25 cooperates with the slide groove opened on the outer surface of the reciprocating screw 15 to rotate the No. 4 stirring blade 26, further enhancing the mixing effect, and can push the middle material to both sides without affecting the lifting of the lifting block 27. When the reciprocating screw 15 rotates, it will drive the No. 3 stirring blade 16 to rotate to stir the material in the storage box 5. When the turntable 11 rotates, it can drive the scraper 12 to rotate. The scraper 12 can scrape off the material attached to the inner wall of the mixing barrel 1, which can reduce material waste and enhance the stirring effect.
