Detailed implementation manners
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0026] The present invention provides a novel turbine stirrer for polymerization reaction as Figure 1 shown, including a container member, a cavity for accommodating materials is formed inside the container member, and a stirring member for stirring the materials is rotatably connected inside the cavity.
[0027] Further, two flow guiding members are symmetrically arranged inside the cavity. A flow guiding cavity for guiding the flow of materials is formed between the two flow guiding members. The stirring member is located between the two flow guiding members, and the two flow guiding members are symmetrically distributed along the length direction of the stirring member. The diameter of the flow guiding member gradually decreases from both ends to the middle position.
[0028] As can be seen from the above, during use, the container member is placed at the position where it is needed. After the container member is placed, the materials to be reacted are added into the cavity inside the container member. After the materials are added, the stirring member works, so that the stirring member stirs the materials inside the cavity, thereby assisting the materials to carry out the polymerization reaction. When the stirring member stirs the materials, through the cooperation of the two flow guiding members inside the air, the flow of the materials is guided. And when the materials are flowing, through the cooperation of the two flow guiding members, and since the diameter of the flow guiding member gradually decreases from both ends to the middle position, the stirring flow rates of the flow guiding member at different positions inside the cavity are different, so that the materials inside the cavity are stirred more thoroughly, thereby improving the material mixing efficiency.
[0029] Reference Figures 4 - 6 As shown, regarding the above-mentioned flow guiding member, the flow guiding member includes a first flow guiding cover 8 and a second flow guiding cover 9 which are symmetrically arranged. The diameters of the first flow guiding cover 8 and the second flow guiding cover 9 decrease from both ends to the middle position. And first flow guiding cavities 15 and second flow guiding cavities 16 are respectively formed inside the first flow guiding cover 8 and the second flow guiding cover 9. A communicating hole 17 which is communicated is formed between the first flow guiding cavity 15 and the second flow guiding cavity 16.
[0030] Through the above technical solution:
[0031] During use, the cavity supports the first flow guiding cover 8 and the second flow guiding cover 9. When the stirring member rotates, when the stirring member stirs the materials, through the cooperation of the first flow guiding cavity 15 and the second flow guiding cavity 16 on the first flow guiding cover 8 and the second flow guiding cover 9, the materials are mixed more efficiently.
[0032] Further, as Figures 1 - 3 shown, the container member includes a barrel body 1. A hollow inner cavity 7 is formed inside the barrel body 1. And a feed pipe 4 for adding materials is fixedly connected to the top of the barrel body 1. A discharge pipe 3 for discharging materials is fixedly connected to the bottom of the barrel body 1. A valve 6 is installed on the discharge pipe 3. Based on this, when the materials need to be discharged after the reaction, the valve 6 on the discharge pipe 3 is opened, and the reacted product is guided by the discharge pipe 3, so that the reacted product is discharged through the discharge pipe 3, thereby facilitating the discharge of the reacted product.
[0033] Moreover, in the present utility model, in order to improve the material discharge efficiency, a liquid guiding slope which inclines downward from the inner wall to the middle position is formed at the bottom end inside the inner cavity 7. When the device discharges the reacted product, through the cooperation of the liquid guiding slope, the product can be discharged faster.
[0034] To enable the barrel body 1 to work stably, a plurality of support rods 2 for supporting itself are fixedly connected to the peripheral surface of the barrel body 1 in an annular array. When the barrel body 1 is in use, the barrel body 1 is supported by the support rods 2, making the barrel body 1 more stable during use.
[0035] In addition, referring to Figures 1 - 4 As shown, regarding the above-mentioned stirring member, the stirring member includes a rotating shaft 10, the rotating shaft 10 is rotatably connected to the inside of the inner cavity 7, and three connecting plates 11 are fixedly connected to the rotating shaft 10 in sequence along its own length direction. A plurality of first spoiler plates 12 are fixedly connected to the connecting plates 11 in an annular array. The first flow guide cover 8 and the second flow guide cover 9 are arranged between two adjacent connecting plates 11.
[0036] Through the above technical solution:
[0037] During use, when the material is added to the inside of the inner cavity 7, the rotating shaft 10 rotates, so that the rotating shaft 10 rotates inside the inner cavity 7, and then drives the connecting plate 11 to rotate. The first spoiler plate 12 is driven to rotate by the connecting plate 11, and the material is stirred by the first spoiler plate 12, thereby accelerating the reaction of the material.
[0038] Furthermore, a plurality of second spoiler plates 13 are fixedly connected to the inside of the first flow guide cover 8 in an annular array, and a plurality of third spoiler plates 14 are fixedly connected to the inside of the second flow guide cover 9 in an annular array. The inclination angles of the second spoiler plates 13 and the third spoiler plates 14 are the same, and the inclination angles of the second spoiler plates 13 and the third spoiler plates 14 are opposite to those of the first spoiler plates 12. Based on this, when the first spoiler plates 12 stir the material, the third spoiler plates 14 are supported by the second flow guide cover 9. When the material enters the first flow guide cover 8 and the second flow guide cover 9, the flow direction of the material is changed by the cooperation of the second spoiler plates 13 and the third spoiler plates 14, thereby further improving the efficiency of material mixing.
[0039] Furthermore, a motor 5 is fixedly connected to the top of the barrel body 1, and the output end of the motor 5 is connected to the rotating shaft 10. Based on this, when it is necessary to drive the motor 5 to rotate, the motor 5 works, thereby driving the rotating shaft 10 to rotate. The connecting plate 11 and the first spoiler plate 12 can be driven to rotate by the rotating shaft 10, thereby stirring and mixing the material.
[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
