In the present embodiment, a stirring apparatus further includes a plurality of legs 11 and a driving motor. The mixing tank 1 is mounted on top of a plurality of legs 11. The driving motor is installed in agitator 1 for drive shaft 2 rotates, specifically, sets up fixed cover on shaft 2 and has connect gasket 23, and gasket 23 contacts with the bottom of agitator 1. The bottom of the stirring barrel 1 is also provided with a discharge outlet 12, so that the stirred paper pulp can be discharged conveniently and enter the next treatment process.
When using foretell a kind of agitated vessel to stir the body paper thick liquid on producing domestic paper, drop into the body paper thick liquid that needs the mixing stirring in the agitator 1, start driving motor, driving motor drive pivot 2 is around self axis along the overlooking anticlockwise rotation of from the top down looking to drive side shaft 3 through a plurality of support horizontal poles 21 and square pole 22 and rotate, side shaft 3 drives rabbling mechanism and begins to rotate along with pivot 2, body paper thick liquid by intensive mixing.
When the density of the raw paper pulp on the upper side in the stirring barrel 1 is larger, the resistance force on the upper side sensing plate 4 is larger than the resistance force on the lower side sensing plate 4, the upper side sensing plate 4 moves upwards under the action of the resistance force of the raw paper pulp, and the outer rod of the third telescopic rod 41 drives the driving ring 71 to move upwards, the driving ring 71 drives the top pillar 9 to slide upwards along the vertical groove 35, so that the upper second telescopic rod 8 compresses when the top pillar 9 slides upwards along the vertical groove 35, the second telescopic rod 8 close to the upper side of the rotating shaft 2 drives the cross rod 84 connected with the top pillar to move towards one side close to the rotating shaft 2, the second telescopic rod 8 far away from the upper side of the rotating shaft 2 drives the cross rod 84 connected with the top pillar to move towards one side close to the rotating shaft 2, the second telescopic rod 8 close to the lower side of the rotating shaft 2 drives the cross rod 84 connected with the top pillar to move towards one side far away from the rotating shaft 2, the lower telescopic rod far away from the rotating shaft 2 drives the cross rod 84 connected with the top pillar to move towards one side far away from the rotating shaft 2, therefore, the four rotating shafts 2 of each stirring mechanism drive the two guide plates 5 to become that the upper sides are close to the rotating shafts 2, and the lower sides are far away from the rotating shafts 2. (as shown in FIG. 12)
When the rotating speed of the rotating shaft 2 reaches a constant value and the driving ring 71 drives the top pillar 9 to come to the notch of the annular groove 34, because the guiding plate 5 always has a tendency of rotating clockwise in a overlooking direction under the resistance of the raw paper pulp, the guiding plate 5 drives the top pillar 9 to enter the corresponding annular groove 34 through the second telescopic rod 8, the hinge block 711 and the top pillar cylinder 712 and rotate clockwise along the annular groove 34, because the top pillar 9 contacts the friction surface of the first limit bulge 36 when rotating clockwise along the annular groove 34, and the top pillar 9 moves outwards to compress the compression spring 91, the rotating speed of the guiding plate 5 and the sensing plate 4 is slow, so that the time for the guiding plate 5 to keep in an original state is long, the raw paper pulp with high density on the upper side is conveniently guided downwards when the guiding plate 5 rotates with the rotating shaft 2, the rotating speed of the top pillar 9 is fast when the guiding plate 5 is driven to rotate continuously after the friction surface of the top pillar 9 slides out, therefore, the guide plate 5 rotates around the side shaft 3 to a state that the upper end is far away from the rotating shaft 2 and the lower end is close to the rotating shaft 2, the time is short, and the time for guiding the base paper pulp upwards is shortened.
If the density of the raw paper pulp on the upper and lower sides is the same after the guide plate 5 rotates for a circle, the acting force of the raw paper pulp on the sensing plates 4 on the upper and lower sides is balanced, and the top pillar 9 moves downwards under the action of the gravity of the guide plate 5, the sensing plates 4 and the drive ring 71, so that the drive ring 71, the guide plate 5 and the sensing plates 4 are driven to return to the initial positions.
If the density of the upper raw pulp is still higher than that of the lower raw pulp after the top pillar 9 rotates one circle, the top pillar 9 will rotate around the corresponding ring groove 34 again.
If the density of the lower raw paper pulp is greater than that of the upper raw paper pulp after the top pillar 9 rotates for a circle, the acting force of the lower raw paper pulp on the lower sensing plate 4 is greater than the upward acting force on the upper sensing plate 4, so the lower sensing plate 4 moves downward and drives the driving ring 71 to move downward through the outer rod, the driving ring 71 drives the top pillar 9 to slide downward along the vertical groove 35, the lower second telescopic rod 8 compresses when the top pillar 9 slides downward along the vertical groove 35, the lower second telescopic rod 8 close to the rotating shaft 2 drives the cross rod 84 connected with the same to move to the side close to the rotating shaft 2, the lower second telescopic rod 8 far away from the rotating shaft 2 compresses and drives the cross rod 84 connected with the same to move to the side close to the rotating shaft 2, the upper second telescopic rod 8 extends, the upper second telescopic rod 5 close to the rotating shaft 2 drives the cross rod 84 connected with the same to move to the side far away from the rotating shaft 2, keep away from the second telescopic link 5 of the upside of pivot 2 and drive the horizontal pole 84 rather than being connected and remove to the one side of keeping away from pivot 2, so four pivots 2 of every rabbling mechanism drive two guide boards 5 and become the upside and keep away from pivot 2, and the downside is close to pivot 2.
When the driving ring 71 drives the top pillar 9 to slide downwards to the notch of the corresponding one of the ring grooves 34, the guide plate 5 starts to rotate around the side shaft 3 in the clockwise direction in the plan view under the resistance of the raw paper pulp, the top pillar 9 enters the corresponding ring groove 34 and rotates clockwise along the ring groove 34, since the top post 9 is contacted to the frictional surface of the second limit projection 37 when rotating clockwise along the ring groove 34, and the ejection pillars 9 move outward to compress the compression springs 91, so that the guide plates 5 and the induction plates 4 rotate at a slower speed, the time for the guide plate 5 to be kept in the original state is longer, the guide plate 5 is convenient to guide the raw paper pulp with higher density on the lower side upwards when rotating around the rotating shaft 2, and the rotating speed of the top column 9 is faster when the top column 9 slides out of the friction surface and continues to rotate, so that the time for the guide plate 5 to rotate around the side shaft 3 until the upper end is close to the rotating shaft 2 and the lower end is far away from the rotating shaft 2 is shorter, and the time for guiding the raw paper pulp downwards is shortened.
That is, the inclination direction of the guide plate 5 is continuously adjusted according to the density of the raw paper pulp in the process of stirring the raw paper pulp, so that the raw paper pulp is stirred uniformly, and the raw paper pulp is prevented from precipitating in the stirring process.
