For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1-Figure 4 As shown, a novel structure powder and particle mixer includes a mixing bin 1, which is composed of an upper cylindrical silo 101 and a lower conical silo 102. The top surface of the upper cylindrical silo 101 is connected and fixed with a feed pipe 103, and the bottom surface of the lower conical silo 102 is provided with a discharge pipe 104. The interior and top surface of the upper cylindrical silo 101 are provided with mixing components, and the mixing component includes a first motor 2 fixed on the top surface of the upper cylindrical silo 101, and the output shaft of the first motor 2 extends to the interior of the mixing bin 1. The output shaft end of the first motor 2 is fixed with a main stirring blade 201, and the top surface of the upper cylindrical silo 101 is provided with a discharge vacuum tank 202.

[0024] like Figure 1-Figure 4 As shown, in this embodiment, the suction port of the unloading vacuum tank 202 is connected and fixed with a circulation pipe 203, and the circulation pipe 203 is a U-shaped structure. The end of the circulation pipe 203 away from the unloading vacuum tank 202 is connected and fixed to the outer wall of the lower conical silo 102. The main stirring blade 201 is used to mix and stir the materials inside the mixing bin 1, and then the unloading vacuum tank 202 is used to continuously transport the materials in the lower layer to the upper layer of the mixing bin 1, so that the materials can flow back and forth up and down in the mixing bin 1, removing the mixing dead corners, and can be evenly dispersed and mixed in the shortest time.

[0025] like Figure 1-Figure 4As shown, in this embodiment, the main stirring blade 201 is a spiral stirring blade, and the length of the spiral stirring blade is four-fifths of the total depth of the inner cavity of the mixing bin 1. By setting the main stirring blade 201 as a spiral stirring blade, the main stirring blade 201 can continuously transport the material in the upper layer of the mixing bin 1 to the lower layer while stirring the mixed material, thereby accelerating the speed of the material flowing back and forth in the mixing bin 1 and increasing the mixing efficiency.

[0026] like Figure 1-Figure 4 As shown, in this embodiment, the bottom discharge port of the unloading vacuum tank 202 is connected and fixed with a first flap valve 3, the first flap valve 3 is connected and fixed to the top surface of the upper cylindrical silo 101, and the bottom discharge port of the lower conical silo 102 is connected and fixed with a second flap valve 301, the bottom surface of the second flap valve 301 is connected and fixed to the top surface of the discharge pipe 104, and by arranging the first flap valve 3 and the second flap valve 301, the unloading vacuum tank 202 and the discharge pipe 104 can be opened and closed, so as to control the discharge and discharge of materials in an orderly manner.

[0027] like Figure 1-Figure 4 As shown, in this embodiment, two second motors 4 are fixed to the outer wall of the lower conical silo 102, and the two second motors 4 are arranged in mirror symmetry with the axis of the mixing silo 1 as the center line. The output shaft of the second motor 4 extends to the interior of the lower conical silo 102, and a flying knife stirring blade 401 is fixed to the output shaft end of the second motor 4. By arranging two flying knife stirring blades 401 on the outer wall of the lower conical silo 102, the two flying knife stirring blades 401 are used to perform secondary stirring and mixing on the material in the process of gathering and flowing toward the bottom surface of the lower conical silo 102, thereby increasing the mixing effect and speed of the material.

[0028] like Figure 1-Figure 4 As shown, in the present embodiment, when the axis of the flying knife stirring blade 401 is toward the bottom surface of the mixing bin 1, the included angle with the axis of the mixing bin 1 is forty-five degrees, and when the axis of the flying knife stirring blade 401 is toward the top surface of the mixing bin 1, the included angle with the axis of the mixing bin 1 is one hundred and thirty-five degrees. By setting the angle of the axis of the flying knife stirring blade 401 toward the bottom surface of the mixing bin 1 to be forty-five degrees, the two ends of the two flying knife stirring blades 401 are not parallel, so that the length of the two flying knife stirring blades 401 that can be set in the lower conical silo 102 is longer, thereby increasing the stirring effect on the material.

[0029] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: in use, the material to be stirred is input into the mixing bin 1 through the feed pipe 103, and then the main stirring blade 201 is driven to rotate by starting the first motor 2. Since the main stirring blade 201 adopts a spiral stirring blade, the main stirring blade 201 can continuously transport the material in the upper layer of the mixing bin 1 to the lower layer while stirring the mixed material. At this time, the material is dispersed and mixed in the mixing bin 1 and flows downward. By starting the unloading vacuum tank 202 and opening the first flap valve 3, the material in the lower layer is transported to the lower layer. The material is continuously conveyed to the upper layer of the mixing bin 1, so that the material can flow back and forth up and down in the mixing bin 1. When the material flows into the lower cone silo 102, it will gather and flow toward the bottom of the lower cone silo 102 due to its internal conical cavity. At this time, the second motor 4 is started to drive the flying knife stirring blade 401 to perform secondary stirring and mixing on the gathered material, thereby further increasing the mixing effect and speed. When the material is mixed, the discharge vacuum tank 202, the first motor 2, and the second motor 4 are closed, and the first flap valve 3 is started to close the discharge vacuum tank 202, and then the second flap valve 301 is opened to discharge the mixed material.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
