[0002] During the papermaking process, waste paper needs to be placed in a water tank for stirring to fully disperse the fibers. Currently, the most commonly used stirring device is a fixed single-paddle stirring device, where the paddle is fixed in position within the stirring tank and cannot be moved. This is especially true when the stirring tank has a flat bottom. This can cause sediment to accumulate at the bottom and corners of the tank, resulting in uneven mixing of the paper pulp.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1The papermaking pulping agitator shown includes a stirring tank 1 having an arc-shaped bottom. A stirring plate 2 is provided in the stirring tank 1, the bottom curvature of which matches the curvature of the tank bottom. The bottom of the stirring plate 2 is close to the bottom of the stirring tank 1. The stirring plate 2 synchronously swings and rotates in the stirring tank 1, thereby breaking up and stirring the paper pulp and preventing sedimentation at the bottom of the tank.

[0018] The stirring plate 2 is suspended in the stirring tank 1 by the support rod 3. Figure 2 As shown, the upper end of the stirring plate 2 is fixedly connected to a rotating shaft 4, to which a first gear 5 is fixed. Rotation of the first gear 5 drives the stirring plate 2 to rotate about the line along which the rotating shaft 4 is located. The first gear 5 is rotatably mounted on a horizontal side of a swing frame 6. The swing frame 6 rotates forward and backward about its horizontal central axis, causing the first gear 5 to swing, thereby driving the rotating shaft 4 and the stirring plate 2 to swing.

[0019] Specifically, the first gear 5 is meshed with the second gear 7, and the first gear 5 and the second gear 7 intersect with each other. The first gear 5 and the second gear 7 are both located in the swing frame 6. The rotating shaft 4 connected to the first gear 5 is rotatably connected to the swing frame 6 via a bearing. The second gear 7 is fixedly connected to the fixed shaft 8, and the fixed shaft 8 is rotatably connected to the swing frame 6 via a bearing. During this process, the second gear 7 remains stationary. A drive shaft 9 is fixedly connected to the horizontal axis of the swing frame 6. The drive shaft 9 is transmission-connected to the motor 10. The motor 10 is connected to supporting components such as a reducer, so that the motor 10 generates a slow and alternating forward and reverse torque. The swing frame 6 is driven to rotate along its horizontal axis by the motor 10; the drive shaft 9 is collinear with the fixed shaft 8.

[0020] During operation, the motor 10 rotates the swing frame 6 via the drive shaft 9. Due to the presence of the rotating shaft 4, the first gear 5 is relatively fixed to a horizontal side of the swing frame 6. Therefore, the first gear 5 swings with the rotation of the swing frame 6. The swing frame 6 rotates within an angle of ±60°, causing the rotating shaft 4 and the stirring plate 2 to swing within ±60°. The second gear 7 remains stationary on the axis of the swing frame 6. Due to the meshing relationship between the first gear 5 and the second gear 7, the first gear 5 rotates during its swing, thereby driving the rotating shaft 4 to rotate, and transmitting the rotation to the stirring plate 2, causing it to rotate.

[0021] In order to ensure the smooth rotation of the driving shaft 9, an extension shaft 11 is connected between the driving shaft 9 and the fixed shaft 8. The extension shaft 11 is fixedly connected to the driving shaft 9, and the extension shaft 11 is rotatably connected to the fixed shaft 8 through a bearing.

[0022] There are multiple support rods 3, preferably four, which are symmetrically installed around the mixing tank 1; the support rods 3 are diagonal braces, and cross bars are fixed on the two support rods 3 on the same side to stabilize the support rods 3.

[0023] The upper end of the support rod 3 is integrally connected to a vertically extending vertical plate frame 12; the other ends of the drive shaft 9 and the fixed shaft 8 are both connected to the vertical plate frame 12, wherein the drive shaft 9 is rotatably connected to the vertical plate frame 12 through a bearing, and the fixed shaft 8 is fixedly connected to the opposite vertical plate frame 12.

[0024] A receiving plate frame 13 is also fixed to the vertical plate frame 12, and the motor 10 is mounted on this receiving plate frame 13. In this embodiment, the motor 10 is mounted parallel to the drive shaft 9 and is driven by a set of spur gears. A through hole 14 is formed in the receiving plate frame 13 corresponding to the rotating shaft 4. The shape of the through hole 14 is based on the swing range of the rotating shaft 4.

[0025] The surface of the stirring plate 2 is provided with a plurality of through-holes 15, which reduce the resistance of the stirring plate 2 in the pulp. A flat connecting rod 16 is fixedly connected between the stirring plate 2 and the rotating shaft 4. This connecting rod 16 connects the circular rotating shaft 4 and the flat stirring plate 2, further stabilizing the connection. Lightening holes 17 are provided in the connecting rod 16 to reduce its weight and energy consumption.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
