Although the above device can fully stir the raw materials during use, the raw materials are prone to dust during the process of inputting and stirring. After the dust floats out of the equipment, it affects the on-site environmental quality and causes waste of the raw materials. Therefore, a material mixing device for preparing oseltamivir phosphate particles is proposed. Utility Model Content

[0007] The bottom of the mixing barrel is rotatably connected with a penetrating stirring shaft, the top of the stirring shaft is fixedly connected with a driving shaft, and the two ends of the driving shaft are respectively used in conjunction with two wedge blocks.

[0008] As a further solution of the utility model, a motor is fixedly connected to the bottom of the mixing barrel, one end of the motor output shaft is fixed to the stirring shaft, and the circumference of the stirring shaft is fixedly connected to a plurality of stirring blades for stirring the raw materials, and one side of the stirring blades is set as an inclined surface.

[0009] As a further solution of the utility model, two symmetrical guide boxes are fixedly connected to the circumference of the mixing barrel, and the guide boxes are both connected to the mixing barrel.

When the stirring shaft rotates, it also drives the drive shaft to rotate, and the drive shaft contacts the wedge block. As the drive shaft rotates, the filter screen is lifted up by the wedge block, and then the filter screen falls under the action of the spring and contacts the support block through the bottom ring to make the filter screen vibrate, which is convenient for shaking off impurities on the filter screen. When the filter screen does not need to be cleaned, the two-way threaded rod is rotated, and the two-way threaded rod drives the top block to move, thereby lifting the filter screen upward, so that the drive shaft and the wedge block are separated.
