Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and more specifically, to a resin raw material mixing tank. Background Technology

[0002] In existing resin raw material mixing tanks, the stirring device typically uses an axial stirring paddle. This method results in a very unidirectional flow of raw materials within the mixing tank, leading to uneven mixing, especially during the mixing of different materials, which may cause stratification and thus affect the quality and stability of the final product.

[0003] Furthermore, the mixing area of ​​the agitator is relatively small, failing to cover the inner edges of the vessel, especially the material near the inner wall, which is more prone to stratification or clumping due to low mixing efficiency. This mixing method not only affects the mixing effect but may also lead to the final product's quality and uniformity failing to meet expected standards.

[0004] In summary, the current resin raw material mixing tank has shortcomings in its stirring method. The stirring paddle rotating in one direction makes the flow direction of the raw materials very singular, resulting in insufficient mixing of the materials in the tank. Utility Model Content

[0005] The purpose of this invention is to provide a resin raw material mixing vessel that can provide multi-directional stirring in both axial and radial directions, and achieve stirring coverage of the inner edge area of ​​the vessel body through the combined motion of rotation and revolution, thereby preventing the formation of stirring dead zones.

[0010] In some embodiments, the auxiliary stirring mechanism includes a secondary stirring shaft, one end of which is coaxially fixed in the middle of the planetary gear; a plurality of second stirring blades are arranged vertically on the outer side of the secondary stirring shaft.

[0027] Please see Figures 1-2 As shown, the resin raw material mixing tank provided in this embodiment includes a tank body 1. The tank body 1 is provided with a spiral turbine composite stirring mechanism inside, which is driven to rotate by a driving mechanism at the top of the tank body 1. The tank body 1 is also provided with a plurality of auxiliary stirring mechanisms, which are sleeved around the outside of the spiral turbine composite stirring mechanism by a planetary transmission mechanism.

[0028] Furthermore, the spiral turbine composite stirring mechanism includes a main stirring shaft 2 connected to the drive mechanism. A spiral first stirring blade 3 is coaxially sleeved on the outer side of the main stirring shaft 2. The inner side of the first stirring blade 3 is fixedly connected to the outer side of the main stirring shaft 2 through a support rod 4. A trumpet-shaped impeller 5 with its expansion opening facing downward is also fixedly sleeved on the outer side of the main stirring shaft 2. A plurality of guide plates 6 are evenly distributed around the surface of the trumpet-shaped impeller 5. The trumpet-shaped impeller 5 is located below the first stirring blade 3.

[0029] Furthermore, the planetary transmission mechanism includes a sun gear coaxially fixedly sleeved on the outside of the main stirring shaft 2 and a gear ring 8 coaxially fixedly sleeved on the inner side wall of the vessel body 1. Multiple planetary teeth 9 are evenly distributed and meshed around the gear ring 8 and the sun gear 7. The auxiliary stirring mechanism is coaxially fixedly arranged in the middle of the planetary teeth 9.

[0030] Furthermore, the auxiliary stirring mechanism includes a secondary stirring shaft 10, one end of which is coaxially fixed in the middle of the planetary gear 9; a plurality of second stirring blades 11 are arranged vertically on the outer side of the secondary stirring shaft 10.

[0031] Furthermore, the auxiliary stirring shaft 10 is rotatably mounted on the stabilizing ring 12, and the stabilizing ring 12 is coaxially arranged with the main stirring shaft 2.

[0032] Furthermore, a stirring paddle 13 is fixedly and coaxially disposed at the bottom end of the auxiliary stirring shaft 10, and the stirring paddle 13 is disposed below the stabilizing ring 12.

[0033] The main stirring shaft 2 is driven to rotate by the drive mechanism, causing the spiral first stirring blade 3 on the main stirring shaft 2 to rotate. This creates an axial thrust stirring of the material inside the vessel body 1, lifting the material from the bottom to the top. Simultaneously, the trumpet-shaped impeller 5 begins to rotate, and the guide plate 6 on the surface of the trumpet-shaped impeller 5 rotates around the main stirring shaft 2, diffusing the material towards the vessel wall and forming three-dimensional turbulence, thereby stirring the material inside the vessel body 1 in multiple directions. In addition, the rotation of the main stirring shaft 2 drives the sun gear 7 to rotate, and under the synergistic action of the gear ring 8, the planetary gear 9 revolves around the sun gear 7 in the same direction as the main stirring shaft 2, thus driving the revolution of the auxiliary stirring shaft 10. Furthermore, the planetary gear 9 rotates under the action of gear transmission, thereby causing the auxiliary stirring shaft 10 to rotate around its own axis, driving the second stirring blade 11 to stir the material. The combined motion of rotation and revolution achieves stirring coverage of the inner edge area of ​​the vessel body 1, preventing the formation of stirring dead zones. The agitator 13 at the bottom of the auxiliary agitator shaft 10 agitates the material at the lowest point inside the vessel body 1 to prevent accumulation.

[0034] Furthermore, the drive mechanism includes a frame 14 sealed on the top of the vessel body 1, a reducer 15 is provided above the frame 14, a motor 16 is connected above the reducer 15, and the top end of the main stirring shaft 2 passes through the frame 14 and is connected to the reducer 15.

[0035] The main stirring shaft 2 is driven to rotate and stir through the coordinated action of the motor 16 and the reducer 15.

[0036] Furthermore, temperature regulating pipes 17 are arranged around the inside of the side wall of the vessel body 1.

[0037] The temperature control pipeline 17 is connected to an external cooling water or heating water pump station through interfaces at both ends, thereby regulating the temperature of the material inside the vessel 1 to meet production needs.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
