[0041] Next, in combination with the specific embodiments of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0042] As Figure 1-7 shown, the kraft paper pulp stirring device of the present utility model includes a tank body 1, a support frame 2, a rotating shaft 3, a stirring blade 4, a speed reducer 5, a heating tank 6 and a heating rod 7.

[0043] Among them, the tank body 1 is used to provide a stirring environment for the kraft paper pulp. The tank body 1 is provided with a feed inlet 101, and the pulp is added into the tank body 1 through the feed inlet 101 for stirring.

[0044] The support frame 2 is used to support the rotating shaft 3, and the support frame 2 is fixedly arranged on the bottom side inside the tank body 1.

[0045] The rotating shaft 3 is used to carry the stirring blade 4. The rotating shaft 3 includes a fixed shaft 31, a fixed cylinder 32, and a detachable shaft 33. Among them, the fixed shaft 31 is rotatably arranged on the tank body 1 and penetrates through its top side; the fixed cylinder 32 is fixedly arranged at the lower end of the fixed shaft 31, and a perforation 301 is provided on its circumferential side; the bottom end of the detachable shaft 33 is abutted against the support frame 2, and its top end is detachably fixed in the fixed cylinder 32 and can move to the outside of the fixed cylinder 32 along the perforation 301; after the stirring device is used up, separate the top end of the detachable shaft 33 from the fixed cylinder 32 and let it move to the outside of the fixed cylinder 32 along the perforation 301, then the detachable shaft 33 can be disassembled.

[0046] The stirring blade 4 is used to stir the slurry. The stirring blade 4 is fixedly arranged on the detachable shaft 33, so that the stirring blade 4 can be removed together with the detachable shaft 33. The length of the stirring blade 4 is less than the inner diameter of the feed inlet 101. Therefore, it is convenient to take out the stirring blade 4 and the detachable shaft 33 from the feed inlet 101, so as to clean the inside of the device, as well as the stirring blade 4 and the detachable shaft 33, which is beneficial to ensuring the cleanliness of the device.

[0047] The fixed shaft 31 is used to connect with the driving device that rotates the rotating shaft 3. It is rotatably arranged on the tank body 1 and will not move with the disassembly of the detachable shaft 33 and the stirring blade 4. Therefore, it can also ensure that the connection relationship between the rotating shaft 3 and the rotating shaft 3 driving structure will not be damaged.

[0048] As Figure 2 and Figure 4 shown, the detachable shaft 33 includes a shaft body 331, a sliding column 332, a sliding cylinder 333, and a reinforcing block 334. Among them, the lower end of the shaft body 331 is abutted against the support frame 2; the sliding column 332 is fixedly arranged at the upper end of the shaft body 331, and its upper end is located inside the fixed cylinder 32; the sliding cylinder 333 is arranged outside the sliding column 332 and can slide along its axial direction with the sliding column 332, and the sliding cylinder 333 is detachably fixed in the fixed cylinder 32, preferably fixed by bolts; as Figure 3 shown, when the sliding cylinder 333 is slid downward to separate the sliding cylinder 333 from the fixed cylinder 32, the sliding column 332 can move to the outside of the fixed cylinder 32 along the perforation 301, so as to remove the detachable shaft 33 from the fixed cylinder 32 by tilting the detachable shaft 33.

[0049] As Figure 2 and Figure 4 shown, the reinforcing block 334 is fixedly arranged on the sliding cylinder 333 and slidably arranged in the perforation 301, so as to reinforce the sliding cylinder 333 and the fixed cylinder 32 and prevent relative rotation between the two.

[0050] As Figure 4As shown, in order to prevent relative rotation between the sliding column 332 and the sliding cylinder 333, it is preferable that the cross-section of the sliding column 332 and the cross-section inside the sliding cylinder 333 are both oblong. Of course, they can also be set to other non-circular shapes.

[0051] To ensure the stable rotation of the rotating shaft 3, the detachable shaft 33 abuts against and is rotatably connected to the top side of the support frame 2, as Figure 5 shown. A limiting groove 201 is formed on the top side of the support frame 2. The limiting groove 201 is in a tapered shape that is wider at the top and narrower at the bottom. The bottom end of the detachable shaft 33 abuts and is arranged in the limiting groove 201. The limiting groove 201 can not only provide good support for the bottom end of the detachable shaft 33, but also allow the detachable shaft 33 to tilt in the limiting groove 201 to facilitate the disassembly of the detachable shaft 33.

[0052] To improve the stirring performance of this stirring device, a plurality of stirring blades 4 are provided, and the plurality of stirring blades 4 are spirally arranged along the axial direction of the rotating shaft 3.

[0053] The stirring blade 4 includes a hoop 41 and a stirring plate 42. Among them, the hoop 41 is fixedly arranged on the rotating shaft 3 in a rotatable manner, as Figure 6 shown. The hoop 41 includes a cylindrical structure arranged outside the rotating shaft 3 and capable of rotating with the rotating shaft 3 and a bolt; a stirring plate 42 is fixedly arranged on each hoop 41. After the stirring plate 42 rotates to the designated position, the bolt can be tightened to fix the position of the stirring plate 42. When it is necessary to take out the stirring blade 4 and the detachable shaft 33 from the tank body 1, the space occupied by the plurality of stirring plates 42 arranged along the spiral path is relatively large and it is not easy to pass through the feed inlet 101. Therefore, the above bolt can be loosened to make the plurality of stirring blades 4 arranged parallel to the axial direction of the rotating shaft 3, so that the combined structure of the stirring blade 4 and the detachable shaft 33 can easily pass through the feed inlet 101 and improve its disassembly efficiency.

[0054] The speed reducer 5 is used to drive the rotation of the rotating shaft 3. The speed reducer 5 is fixedly arranged on the tank body 1, and its output end is coaxially and fixedly connected to the fixed shaft 31.

[0055] As Figure 7 shown, the speed reducer 5 is arranged at the middle position on the top side of the tank body 1; two feed inlets 101 are arranged on the top side of the tank body 1, and the two feed inlets 101 are oppositely arranged on both sides of the tank body 1 to increase the cross-sectional area of the feed inlet 101 and accelerate the feeding efficiency of the material; the feed inlet 101 is in an arc shape, which is in a slender structure, and the maximum value of the inner diameter of the feed inlet 101 is greater than the maximum value of the outer diameter of the stirring blade 4, so as to facilitate the passage of the stirring blade 4 and the detachable shaft 33 through the feed inlet 101.

[0056] The heating tank 6 and the heating rod 7 are used to provide an appropriate temperature for the material being stirred, as Figure 1As shown, the tank body 1 is fixedly arranged in the heating tank 6, and there is a gap between the two, which is used to fill the heating medium; the heating rod 7 is fixedly penetrated on the heating tank 6 to heat the heating medium, so as to transfer the heat in the heating medium to the slurry in the tank body 1.

[0057] The usage method of the kraft paper pulp stirring device of the present utility model is as follows:

[0058] When the rotating shaft 3 is in normal use, it is in the state as Figure 2 shown. When the stirring device needs to be cleaned, as Figure 3 shown, first loosen the connection structure between the sliding cylinder 333 and the fixed cylinder 32, and slide the sliding cylinder 333 downward to move the sliding column 332 through the through hole 301 to the outside of the fixed cylinder 32, so that the detachable shaft 33 is separated from the fixed cylinder 32, and then loosen the Figure 6 bolts shown in, rotate the stirring plate 42 to make multiple stirring plates 42 arranged in parallel, and finally take out the combined structure of the detachable shaft 33 and the stirring blade 4 from the feed port 101 to clean the combined structure of the detachable shaft 33 and the stirring blade 4 and the inside of the tank body 1. After the cleaning is completed, reverse the above steps and assemble the device in the manner as Figure 1 shown.
