Description

Technical Field

[0001] The present application relates to the technical field of polymer material production, and in particular to a stirring paddle and a stirring device for high-viscosity rubber. Background Art

[0002] In the production process of some resins, stirring is an essential step, through which the homogeneous and heterogeneous systems are fully mixed or dispersed for reaction.

[0003] Some resins have high viscosity. When they are stirred with traditional stirring mechanisms, due to the small shear force and poor mixing ability in the axial direction, it is easy to cause serious stratification of the rubber and increase the molecular weight difference in the axial direction. In addition, when adding some preparations for mixing, if the uniformity of stirring cannot be guaranteed, it will lead to excessive local concentration and rapid local reaction, resulting in an increase in by-products. Therefore, both the uniformity of stirring and the efficiency of stirring will affect the quality of the rubber. Utility Model Content

[0004] The purpose of the present application is to provide a stirring paddle and a stirring device for high-viscosity rubber to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a stirring paddle and a stirring device for high-viscosity rubber. In a first aspect, the present application provides a stirring paddle for high-viscosity rubber, comprising a V-shaped main body and a first folded edge portion and a second folded edge portion extending toward two ends of the V-shape;

[0006] A plurality of first through holes penetrating along the thickness direction of the first folded edge portion and the second folded edge portion are provided;

[0007] The V-shaped angle of the main body is 100°-135°, and the angles between the first folded edge, the second folded edge and the main body are 90°-150°;

[0008] In the above-mentioned implementation process, the stirring paddle main body, the first folded edge part and the second folded edge part provided by the present scheme constitute a structure that is approximately C-shaped, and the structure itself has a certain blocking surface, so that the slurry can be stirred when it rotates in coordination; wherein, the first folded edge part and the second folded edge part provided by the present scheme are formed with a first through hole, and when the stirring paddle of the present application is used for stirring, as the stirring paddle moves, part of the slurry will pass through the first through hole at a certain speed. Since there is a certain angle between the first folded edge and the second folded edge and the main body, the slurry passing through the first through hole at this time can form an impact force in the longitudinal direction or at a certain angle with the longitudinal direction, thereby achieving mixing of the slurry in the longitudinal direction; it can be understood that the present scheme can simultaneously achieve mixing of the slurry in the transverse and longitudinal directions, effectively alleviating the problem of poor longitudinal mixing ability of traditional stirring paddles.

[0009] Preferably, a plurality of second through holes are provided on both sides of the V-shape of the main body along their respective thickness directions;

[0010] In the above implementation process, the present solution further provides a second through hole on the main body, which can form a material-dividing and cutting effect during the stirring process, and helps to further promote the full mixing of the rubber material, especially the rubber material with higher viscosity.

[0011] Preferably, a plurality of the first through holes are arranged along a first direction;

[0012] A plurality of the second through holes are arranged along a first direction; the first direction is parallel to the axial direction of the main body.

[0013] Preferably, the thickness of the first folded edge portion and the second folded edge portion gradually decreases in a direction away from the main body portion.

[0014] In the above implementation process, this solution can effectively enhance the structural strength by further optimizing the thickness distribution relationship between the first folded edge portion and the second folded edge portion, ensuring that it has a strong colloid cutting ability while also taking into account the structural strength of the stirring paddle itself and extending its service life.

[0015] Preferably, the longitudinal sections of the first folded edge portion and the second folded edge portion are triangular;

[0016] In the above implementation process, the longitudinal sections of the first folded edge portion and the second folded edge portion in this solution are triangular, which can be understood as having relatively sharp edges. This can effectively improve the cutting strength of the colloid during the coordinated rotation and promote the colloid to quickly enter a uniformly mixed state.

[0017] Preferably, V-shaped notches are provided on the first folded edge portion and the second folded edge portion.

[0018] Preferably, the main body has a symmetrical structure, and the first folded edge portion and the second folded edge portion are symmetrical to each other about the symmetry axis of the main body.

[0019] Preferably, the V-shaped notches of the first folded edge portion are respectively connected to two outer corners of the first folded edge portion;

[0020] The V-shaped notches of the second folded edge portion are respectively connected to two outer corners of the second folded edge portion; the V-shaped notches are symmetrical in structure;

[0021] In the above implementation process, the present solution further provides a V-shaped notch on the first folded edge portion and the second folded edge portion, so as to make the two corners thereof sharper, thereby further improving the ability to cut the rubber and improve the ability to mix the high-viscosity rubber.

[0022] In a second aspect, the present application provides a stirring device, comprising a stirring barrel, a rotating drive member, a rotating shaft, a mounting disc, and a stirring paddle as described above;

[0023] The mixing barrel is formed with a containing space, the rotating driving member is arranged on the mixing barrel and its driving end is connected to the rotating shaft, and the mounting disc is arranged coaxially with the rotating shaft;

[0024] The stirring paddles are provided in plurality and are arranged around the mounting disc, and the main body is connected to the mounting disc;

[0025] In the above implementation process, the rotating drive member drives the rotating shaft to rotate, the mounting disc is coaxially arranged with the rotating shaft, and the stirring paddle is circumferentially arranged around the disc. When the rotating shaft rotates, the stirring paddle can be driven to rotate around the rotating shaft, thereby achieving stirring of the slurry.

[0026] Preferably, a U-shaped stirring mechanism connected to the rotating shaft is provided below the mounting disc and the stirring paddle;

[0027] In the above implementation process, the present solution further sets a U-shaped stirring mechanism under the mounting disc to form double-layer stirring, which can further improve the stirring efficiency and accelerate the rubber material to reach a homogeneous state.

[0028] Compared with the prior art, the beneficial effects of the present application are: the stirring paddle main body, the first folded edge part and the second folded edge part provided in the present solution constitute a structure that is approximately C-shaped, and the structure itself has a certain blocking surface, so that the slurry can be stirred when it rotates in coordination; wherein, the first folded edge part and the second folded edge part provided in the present solution are formed with a first through hole, and when the stirring paddle of the present application is used for stirring, as the stirring paddle moves, part of the slurry will pass through the first through hole at a certain speed, and since there is a certain angle between the first folded edge and the second folded edge and the main body, the slurry passing through the first through hole at this time can form an impact force in the longitudinal direction or at a certain angle with the longitudinal direction, thereby achieving mixing of the slurry in the longitudinal direction; it can be understood that the present solution can simultaneously achieve mixing of the slurry in the transverse and longitudinal directions, effectively alleviating the problem of poor longitudinal mixing ability of traditional stirring paddles.

[0043] Example

[0044] Some resins have high viscosity. When using traditional stirring mechanisms for stirring, due to the small shear force and poor mixing ability in the axial direction, it is easy to cause serious stratification of the rubber material and increase the molecular weight difference in the axial direction. In addition, when adding some preparations for mixing, if the stirring uniformity cannot be guaranteed, it will lead to excessive local concentration, rapid local reaction, and increase of by-products. Therefore, both the stirring uniformity and stirring efficiency will affect the quality of the rubber material. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0045] For details, see Figure 1-3 , this embodiment provides a stirring paddle for high-viscosity rubber, which includes a V-shaped main body 10 and a first folded edge portion 21 and a second folded edge portion 22 extending toward two ends of the V-shape;

[0046] Specifically, a plurality of first through holes 23 penetrating along the thickness direction of the first folded edge portion 21 and the second folded edge portion 22 are provided;

[0047] The V-shaped angle of the main body 10 is 100°-135°, and the angles between the first folded edge 21 and the second folded edge 22 and the main body 10 are 90°-150°;

[0048] In the above scheme, the stirring paddle main body 10, the first folded edge 21 and the second folded edge 22 provided in the present scheme constitute a structure that is approximately C-shaped, and the structure itself has a certain blocking surface, so that the slurry can be stirred when it rotates in coordination; wherein, the first folded edge 21 and the second folded edge 22 provided in the present scheme are formed with a first through hole 23. When the stirring paddle of the present application is used for stirring, as the stirring paddle moves, part of the slurry will pass through the first through hole 23 at a certain speed. Since there is a certain angle between the first folded edge and the second folded edge and the main body 10, the slurry passing through the first through hole 23 at this time can form an impact force in the longitudinal direction or at a certain angle with the longitudinal direction, thereby achieving mixing of the slurry in the longitudinal direction; it can be understood that the present scheme can simultaneously achieve mixing of the slurry in the transverse and longitudinal directions, effectively alleviating the problem of poor longitudinal mixing ability of traditional stirring paddles.

[0049] Specifically, a plurality of second through holes 11 are provided on both sides of the V-shape of the main body 10 along their respective thickness directions;

[0050] In the above scheme, the present scheme further provides a second through hole 11 on the main body, which can form a similar material dividing and cutting effect during the stirring process, and is helpful to further promote the full mixing of the rubber material, especially the rubber material with higher viscosity.

[0052] Furthermore, the plurality of second through holes 11 are arranged along a first direction; the first direction is parallel to the axial direction of the main body 10 .

[0053] Specifically, the thickness of the first folded edge portion 21 and the second folded edge portion 22 gradually decreases in a direction away from the main body portion 10 .

[0054] In the above scheme, this scheme can effectively enhance the structural strength by further optimizing the thickness distribution relationship between the first folded edge portion 21 and the second folded edge portion 22, ensuring that it has a strong colloid cutting ability while also taking into account the structural strength of the stirring paddle itself and extending its service life.

[0055] Specifically, the longitudinal sections of the first folded edge portion 21 and the second folded edge portion 22 are triangular;

[0056] In the above scheme, the longitudinal sections of the first folded edge portion 21 and the second folded edge portion 22 in this scheme are triangular, which can be understood as having relatively sharp edges, so that the cutting strength of the colloid can be effectively improved during the coordinated rotation, and the colloid can be promoted to quickly enter a uniformly mixed state.

[0057] Specifically, a V-shaped notch 24 is formed on the first folded edge portion 21 and the second folded edge portion 22 .

[0058] Preferably, the main body 10 has a symmetrical structure, and the first folded edge portion 21 and the second folded edge portion 22 are symmetrical to each other about the symmetry axis of the main body 10 .

[0059] Furthermore, the V-shaped notch 24 of the first folded edge portion 21 connects two outer corners of the first folded edge portion 21 respectively;

[0060] Specifically, the V-shaped notches 24 of the second folded edge portion 22 are respectively connected to two outer corners of the second folded edge portion 22; the V-shaped notches 24 are symmetrical in structure;

[0061] In the above scheme, this scheme further opens a V-shaped notch 24 on the first folding edge portion 21 and the second folding edge portion 22 to make the two corners sharper, which can further improve its ability to cut the rubber and improve its ability to mix high-viscosity rubber.

[0062] See also Figure 4 , this embodiment also provides a stirring device, which includes a stirring barrel 31, a rotating driving member 32, a rotating shaft 33, a mounting disc 34 and any stirring paddle as described above;

[0063] Furthermore, the mixing barrel 31 is formed with a containing space, the rotating driving member 32 is arranged on the mixing barrel 31 and its driving end is connected to the rotating shaft 33, and the mounting disc 34 is arranged coaxially with the rotating shaft;

[0064] Specifically, a plurality of stirring paddles are provided and arranged around the mounting disc 34, and the main body 10 is connected to the mounting disc 34;

[0065] In some embodiments, the stirring paddle can be integrally provided with the mounting disc 34; in other embodiments, a fixing method such as a buckle plus a locking screw can also be used to achieve a detachable connection.

[0066] In the above scheme, the rotating drive member 32 drives the rotating shaft 33 to rotate, the mounting disc 34 is coaxially arranged with the rotating shaft 33, and the stirring paddle is circumferentially arranged around the disc. When the rotating shaft 33 rotates, the stirring paddle can be driven to rotate around the rotating shaft 33, thereby achieving stirring of the slurry.

[0067] It should be noted that the specific structure and working principle of the stirring device are relatively mature technologies in the prior art, so this solution will not be further elaborated on.

[0068] Furthermore, a U-shaped stirring mechanism 35 connected to the rotating shaft is provided below the mounting disc 34 and the stirring paddle;
