The following describes a specific working procedure of a stirring device for processing impregnated paper pulp according to the present application in combination with the above embodiments:
Feeding:
Water and pulp stock are fed into the housing 100 from the feed port 120.
Starting:
the first driving motor 220 and the second driving motor 320 are started, the first driving motor 220 directly drives the first stirring shaft 200 to rotate, the second driving motor 320 drives the rotating ring 301 to rotate, the rotating ring 301 drives the plurality of second stirring shafts 300 to revolve around the first stirring shaft 200, the first stirring blades 210 on the first stirring shaft 200 and the second stirring blades 310 on the second stirring shaft 300 push the pulp at the bottom upwards, and as the inclination directions of the first stirring blades 210 on the first stirring shaft 200 and the second stirring blades 310 on the second stirring shaft 300 are opposite, the stirring and mixing effects of the pulp are better, and the rotation directions of the first stirring shaft 200 and the second stirring shaft 300 are opposite, so that the flow speed of the pulp is larger than the rotation speed difference between the first stirring shaft 200 and the second stirring shaft 300, the pulp is scattered by the first stirring blades 210 and the second stirring blades 310, and the mixing degree of the pulp is more uniform.
The rotational speeds of the first driving motor 220 and the second driving motor 320 are adjusted at regular time, so that the rotation speed of the first stirring shaft 200 and the revolution speed of the second stirring shaft 300 are changed, and the critical point of the pulp driven by the first stirring shaft 200 and the critical point of the pulp driven by the second stirring shaft 300 are continuously moved in the radial direction of the shell 100, so that the stirring mixing degree of the pulp is further improved, and if the pulp is mixed unevenly, the pressure sensors on the first stirring blade 210 and the second stirring blade 310 can sense the uneven mixing condition in the stirring mixing process.
When the pulp concentration at the edge of the housing 100 is greater than the pulp concentration at the center of the housing 100:
The increase of the acting force of the pulp received by the pressure sensor on the second stirring blade 310 indicates that the pulp concentration at the edge of the shell 100 is greater than the pulp concentration at the center of the shell 100, the second telescopic piece 330 starts to stretch, the second telescopic piece 330 stretches to drive the connecting ring 341 to move downwards in the shell 100, the connecting ring 341 drives the plurality of second tapered rods 340 to move downwards in the second stirring shaft 300 along the axial direction of the connecting ring, the conical surface of the second tapered rods 340 is contacted with the connection of the plurality of second stirring blades 310 to push the plurality of second stirring blades 310, the plurality of second stirring blades 310 move along the radial direction of the second stirring shaft 300, the axial distance from bottom to top of the second stirring blades 310 gradually increases, a similar conical shape is formed, and the small end faces downwards, so that when the second stirring shaft 300 revolves, the pulp with larger concentration at the edge of the shell 100 is pushed upwards in an inclined direction, the pulp with larger concentration at the edge of the shell 100 gradually flows towards the center of the shell 100, the pulp concentration distribution in the shell 100 is gradually and uniform, and the stirring mixing efficiency of the pulp concentration in the shell 100 is gradually improved. After the pulp concentration distribution is uniform, the second telescopic piece 330 resets to drive the plurality of second tapered rods 340 to reset, after the second tapered rods 340 reset, the connecting shafts 410 of the plurality of second stirring blades 310 are separated from the tapered surfaces of the second tapered rods 340, and the plurality of second stirring blades 310 reset under the action of the elastic piece 430.
When the pulp concentration at the edge of the housing 100 is smaller than the pulp concentration at the center of the housing 100:
The force of the pulp received by the pressure sensor on the first stirring blade 210 increases, which means that the pulp concentration at the center of the shell 100 is greater than that at the edge of the shell 100, the first telescopic member 230 starts to stretch, and the first telescopic member 230 drives the first tapered rod 240 to move downwards along the axial direction of the first stirring shaft 200, so that the tapered surfaces of the first tapered rod 240 are in contact with the connecting shafts 410 of the plurality of first stirring blades 210, the plurality of first stirring blades 210 move along the radial direction of the first stirring shaft 200, the distance between the plurality of first stirring blades 210 and the axis of the first stirring shaft 200 is gradually increased from bottom to top, a similar tapered shape is formed, the small end faces downwards, and when the first stirring shaft 200 rotates, the first stirring blades 210 push the pulp at the center of the shell 100 upwards in an inclined manner, and gradually flow towards the direction close to the edge of the shell 100, so that the pulp concentration inside the shell 100 is uniformly distributed, and the stirring and mixing efficiency of the pulp is improved. After the pulp concentration distribution is uniform, the first telescopic piece 230 resets to drive the first tapered rod 240 to reset, after the first tapered rod 240 resets, the connecting shafts 410 of the plurality of first stirring blades 210 are separated from the conical surfaces of the first tapered rod 240, and the plurality of first stirring blades 210 reset under the action of the elastic piece 430.
Discharging:
After the pulp is uniformly mixed, the discharge port 130 is opened, and the pulp is discharged from the discharge port 130 to the outside of the casing 100.
