[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0024] The utility model provides Figure 1-4The pharmaceutical intermediate purification device shown includes a processing barrel 1, a feed port 2 is provided at the top of the processing barrel 1, a discharge port 3 is provided at the bottom of the processing barrel 1, a filter screen 4 is fixedly connected to the inside of the discharge port 3, and a discharge pipe 5 is fixedly connected to the bottom of the discharge port 3, a motor 6 is fixedly connected to the top wall of the processing barrel 1, and the output shaft of the motor 6 is transmission-connected to the drive shaft 7, and the outer ring of the drive shaft 7 is sleeved with a stirring blade 9, and further includes:
[0025] The linkage assembly 8, the inner wall of the processing barrel 1 is fixedly connected to the sealing frame 801 through the connecting rod 802, the driving shaft 7 is connected to the linkage shaft 805 through the bevel gear set 803, and the outer wall of the linkage shaft 805 is fixedly connected to the stirring blade 2 10, so as to ensure that the two groups of stirring blades rotate back and forth in different directions to stir the material inside the processing barrel 1.
[0026] The motor 6 can rotate forward and reverse, and the rotation angle of the motor 6 is 0-170 degrees. In this way, the angles of the two sets of stirring blades are controllable as the drive shaft 7 and the linkage shaft 805 rotate. During the rotation of the two sets of stirring blades, they will not collide with the connecting rod 802 to affect the subsequent work of the processing barrel 1.
[0027] The outer diameters of the drive shaft 7 and the linkage shaft 805 are equal, and the drive shaft 7 and the linkage shaft 805 are coaxially distributed. The lower end of the linkage shaft 805 is connected to the filter screen 4 through a bearing to ensure that the drive shaft 7 drives the linkage shaft 805 to rotate steadily.
[0028] The drive shaft 7 and the linkage shaft 805 pass through the top and bottom of the sealing frame 801 respectively, and the drive shaft 7 and the linkage shaft 805 are rotatably connected to the through-port through bearings, so that the bevel gear set 803 is located inside the sealing frame 801, ensuring the stability of the bevel gear set 803 during rotation.
[0029] The bevel gear set 803 consists of three meshing bevel gears, and the upper and lower bevel gears are fixedly sleeved on the lower end of the drive shaft 7 and the upper end of the linkage shaft 805 respectively, and the inner ring of the bevel gear in the middle position meshing with the upper and lower bevel gears is sleeved with an auxiliary shaft 804. The auxiliary shaft 804 is rotatably connected to the inner wall of the sealing frame 801 through a bearing, and the rotation of the drive shaft 7 drives the linkage shaft 805 to rotate. Since the gears rotate in different directions due to the meshing of the gears, the drive shaft 7 and the linkage shaft 805 ultimately rotate in different directions.
[0030] The stirring blade 1 9 is in an "N" shape, and the stirring blade 2 10 is in a "U" shape. The stirring blade 1 9 and the stirring blade 2 10 do not contact the sealing frame 801, and the stirring blade 1 9 is mounted on the outer ring of the stirring blade 2 10, which facilitates the driving shaft 7 and the linkage shaft 805 to realize different direction rotation and simultaneously mobilize the two groups of stirring blades to rotate in different directions without interference.
[0031] Working principle: When using a pharmaceutical intermediate purification device, first start the motor 6 to make the motor 6 rotate forward and reverse, and the rotation angle of the motor 6 is controlled at 0-160 degrees. The rotation of the motor 6 mobilizes the rotation of the drive shaft 7 connected to the output shaft of the motor 6, and then mobilizes the rotation of the "N"-shaped stirring blade 9 fixedly connected to the outer wall of the drive shaft 7. The rotation of the stirring blade 9 stirs the material inside the processing barrel 1 evenly, ensuring the efficiency of subsequent purification processing. At the same time, during the rotation of the drive shaft 7, the outer ring of the drive shaft 7 is sleeved with a bevel gear in the bevel gear set 803, and then under the transmission action of the bevel gear set 803, it drives the rotation of the linkage shaft 805 connected to the inner ring of another bevel gear, thereby driving the rotation of the "U"-shaped stirring blade 2 10 on the outer ring of the linkage shaft 805 to stir the material. The gear meshing connector has different rotation angles, so that the stirring blade 1 9 and the stirring blade 2 10 rotate in different directions to stir the material in multiple directions, thereby ensuring its processing efficiency.
[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
