The driving plugging assembly 6 is mounted on the material lifting mixing mechanism 5 by a spring, and the driving plugging assembly 6 is provided with a sealing block 62 that is matched with the slurry inlet groove 50. There are several fixed stirring mechanisms 7 evenly distributed on the outer circumference. The lifting mixing mechanism 5 further includes a lifting cylinder body 51, a connecting frame 52 and a stirring wing 53, the shape of the lifting cylinder body 51 is a hemispherical shell, and the lifting cylinder body 51 is provided with a slurry inlet Through groove 50, the two sides of the slurry inlet through groove 50 are symmetrically provided with sliding grooves 511, the driving plugging assembly 6 penetrates through the sliding groove 511, and the lifting cylinder body 51 is connected to the lifting driving mechanism 4 through the connecting frame 52 The lifting frames 47 are connected, the connecting frames 52 are uniformly distributed around the circumference, and the outer wall of the lifting cylinder body 51 is provided with stirring wings 53 along the direction of its generatrix. The number of the stirring wings 53 is two, and the stirring wings 53 The angle between them is 90 degrees. The driving plugging assembly 6 further includes a mounting plate 61, a sliding rod 63 and an adjusting nut 64. The lower end surface of the mounting plate 61 is provided with a sealing block 62, and the lower end surface of the sealing block 62 is an arc surface. A sliding rod 63 is symmetrically provided below the mounting plate 61, the sliding rod 63 is mounted on the lifting and mixing mechanism 5 by a spring, the lower part of the sliding rod 63 is a threaded part, and the lower part of the sliding rod 63 is installed with an adjusting nut 64. The lifting driving mechanism 4 includes a driving box 40, a mounting box 41, a bevel gear driving shaft 42, a bevel gear driven shaft 43, a driving gear 44, a guide frame 45, a driving frame 46 and a lifting frame 47. A drive box 40 is provided above, and a mounting box 41 is provided below the drive plate 33. The mounting box 41 is provided with a bevel gear drive shaft 42. The drive box 40 drives the bevel gear follower through the bevel gear drive shaft 42 The shaft 43 rotates, the bevel gear driving shaft 42 is perpendicular to the axis of the bevel gear driven shaft 43, the end of the bevel gear driven shaft 43 is connected with a drive gear 44, and the outer wall of the drive frame 46 is provided with teeth The driving gear 44 controls the lifting movement of the driving frame 46 through the rack 461, the driving frame 46 is mounted on the guide frame 45, and a lifting frame 47 is connected below the driving frame 46. The axis coincides with the axis of the drive disc 33. The fixed stirring mechanism 7 includes a connecting rod 71 and a stirring rod 72. The upper end of the connecting rod 71 is connected to the drive plate 33, the lower end of the connecting rod 71 is connected with an annular chassis 73, and the connecting rods 71 ​​are connected with each other. There are several stirring rods 72, and the stirring rods 72 are installed obliquely. The drive base 3 also includes a drive motor 31 and a transmission mechanism 32. The drive motor 31 controls the rotation of the drive disk 33 through the transmission mechanism 32. A control box 11 is provided on one side of the base 1, and the control box 11 is A speed regulating device and a lifting switch are provided, and the control box 11 is matched with the transmission mechanism 32.

[0018] Working process of the present invention:

[0019] The working principle of a pulp stirring device for papermaking of the present invention is as follows: the drive base 3 controls the drive disk 33 to rotate, the fixed stirring mechanism 7, the stirring blade assembly 411 rotates to stir the material, and the drive box 40 controls the lifting frame 47 through a gear transmission mechanism. During the reciprocating movement, when the lifting cylinder body 51 moves downwards, the material exerts an upward impulse on the drive sealing assembly 6 to open the slurry inlet passage 50, and the material located below can enter through the slurry inlet passage 50 In the barrel, the material can drive the plugging assembly 6 to reset when the lifting cylinder body 51 rises, and the slurry inlet channel 50 is closed to transport the material upward. In addition, the stirring wings 53 and the sliding rod 63 that extend out of the lifting cylinder body 51 can Auxiliary mixing can make material mixing more uniform, improve production efficiency and shorten production cycle.

[0020] The above-mentioned embodiment is an illustration of the present invention, but not a limitation of the present invention. Any solution that simply changes the present invention belongs to the protection scope of the present invention.
