Detailed implementation manner

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] The present invention provides a vertical hydrofoil paddle mixer as shown in Figures 1-12 Figure 10, which includes a mixing barrel 1. Both the front and rear sides of the upper end of the mixing barrel 1 are connected with feeding pipes 2. The center of the lower end of the mixing barrel 1 is communicated with a discharging pipe 3. A plurality of support legs 4 are fixedly connected to the outer side of the lower end of the mixing barrel 1. The center of the upper end of the mixing barrel 1 is fixedly connected with a mixing motor 5. The lower end inside the mixing motor 5 is rotatably connected with a mixing shaft 6, and the lower end of the mixing shaft 6 penetrates downward through the inside of the center of the upper end of the mixing barrel 1. A connecting collar 7 is sleeved outside the mixing shaft 6. Both the left and right ends of the connecting collar 7 are fixedly connected with connecting swivel bases 8. Both the left and right ends of the connecting collar 7 are rotatably connected with connecting turntables 9 through the connecting swivel bases 8. A plurality of main mixing paddles 10 are arranged on the outer sides of the centers of the ends of the two connecting turntables 9 away from the connecting swivel bases 8. The mixer imports materials through the two feeding pipes 2 at the upper end and exports the mixed materials through the discharging pipe 3 at the lower end. And the mixing barrel 1 is supported at the bottom by a plurality of support legs 4 on the outer side of the lower end. During the working process of the mixer, the mixing power is provided by the mixing motor 5 at the upper end of the mixing barrel 1. And the mixing motor 5 drives the connecting collar 7 and the connecting swivel base 8 to rotate inside the mixing barrel 1 through the mixing shaft 6, and drives the connecting turntable 9 and a plurality of main mixing paddles 10 to mix and stir the materials through the connecting collar 7 and the connecting swivel base 8. The plurality of main mixing paddles 10 arranged on the outside of the connecting turntable 9 can be increased or decreased according to the mixing needs of the materials to ensure the uniform mixing of the materials.

[0037] Preferably, a limiting ring 11 is fixedly connected to the lower side of the inner wall of the cylindrical stirring barrel 1. A rotating inner sleeve 12 is arranged above the limiting ring 11, and the rotating inner sleeve 12 is rotatably connected between the outer wall of the upper end of the limiting ring 11 and the inner wall of the upper end of the stirring barrel 1. A plurality of rolling balls 13 are rotatably connected to the upper and lower sides and the upper and lower ends of the inner wall of the cylindrical outer wall of the rotating inner sleeve 12.

Limiting rolling grooves 14 are provided inside the outer wall of the upper end of the limiting ring 11 and inside the outer side of the inner wall of the upper end of the stirring barrel 1. And a plurality of rolling balls 13 located inside the upper and lower ends of the rotating inner sleeve 12 are respectively rotatably connected to the two limiting rolling grooves 14. During the process of stirring the materials, the materials will rotate and mix inside the stirring barrel 1 under the stirring of a plurality of main stirring paddles 10. And during the rotation process of the materials, the materials will generate friction with the inner wall of the stirring barrel 1, resulting in a slow increase in the rotation speed of the materials. At this time, a rotating inner sleeve 12 is arranged inside the stirring barrel 1, so that when the materials rotate inside the stirring barrel 1, they will contact the inside of the rotating inner sleeve 12 and generate friction with the inner wall of the rotating inner sleeve 12. Since the rotating inner sleeve 12 is rotatably connected inside the stirring barrel 1 through a plurality of rolling balls 13 arranged on the upper and lower sides, and the upper and lower ends of the rotating inner sleeve 12 are restricted in position by the limiting ring 11 and the inner wall of the upper end of the stirring barrel 1, during the process of the materials generating friction with the rotating inner sleeve 12, the rotating inner sleeve 12 will rotate together with the materials, thereby reducing the friction between the materials and the rotating inner sleeve 12, enabling the materials to quickly increase the rotation speed inside the stirring barrel 1, enabling the materials to be quickly and evenly mixed, improving the material mixing efficiency, and improving the mixing work efficiency of the mixer.

[0038] Preferably, a plurality of communication holes 15 penetrate through the upper and lower parts of the connection between the limiting ring 11 and the stirring barrel 1, and a plurality of communication holes 15 are all located outside the limiting rolling grooves 14.

[0039] Preferably, a plurality of limiting clamping holes 16 are provided inside the front and rear ends of the stirring shaft 6. The central parts of the front and rear ends of the connecting sleeve ring 7 are internally threadedly connected with limiting bolts 17, and the two limiting bolts 17 are clamped inside the stirring shaft 6 through the limiting clamping holes 16 at the front and rear ends, enabling the connecting sleeve ring 7 to adjust the position outside the stirring shaft 6 by the limiting bolts 17 to switch positions between the plurality of limiting clamping holes 16, so that the connecting sleeve ring 7 can adjust the stirring height outside the stirring shaft 6 according to the stirring conditions.

[0040] Preferably, a plurality of connection jacks 18 are provided inside the cylinder of the connection turntable 9.

An auxiliary stirring paddle 22 is rotatably connected to the outside of each of the plurality of connection rotating shafts 21. While the connection turntable 9 drives the plurality of main stirring paddles 10 to rotate, it can drive the plurality of connecting rod sleeves 19 and the plurality of telescopic rods 20 inserted inside the outer wall of the cylinder to rotate, and drive the plurality of connection rotating shafts 21 and the auxiliary stirring paddles 22 to rotate around the stirring shaft 6 inside the stirring barrel 1 through the connecting rod sleeves 19 and the telescopic rods 20, so that the mixer can not only stir the material through the plurality of main stirring paddles 10, but also stir the material through the plurality of auxiliary stirring paddles 22 arranged outside the connection turntable 9.

[0041] Preferably, since an arc-shaped stirring blade is provided outside the auxiliary stirring paddle 22 and is rotatably connected to the outside of the connection rotating shaft 21, and at the same time the connection turntable 9 is rotatably connected to the outside of the connection sleeve ring 7 through the connection base 8, the auxiliary stirring paddle 22 can not only rotate on the outside of the connection rotating shaft 21 under the reaction force of the material, but also rotate around the central axis of the connection turntable 9, and at the same time can rotate around the stirring shaft 6, so that the mixer can not only perform overall stirring of the material by rotating the plurality of main stirring paddles 10 and the plurality of auxiliary stirring paddles 22 around the stirring shaft 6, but also perform local stirring of the material by rotating the plurality of auxiliary stirring paddles 22 around the connection turntable 9 and rotating the auxiliary stirring paddle 22 around the connection rotating shaft 21, thereby improving the efficiency of uniform mixing of the material and further improving the working efficiency of the mixer.

[0042] Preferably, a limit sliding groove 23 is provided inside one end of the telescopic rod 20 away from the connection base 8, and the limit sliding groove 23 is located on the side of the connection rotating shaft 21 close to the connecting rod sleeve 19.

[0043] Preferably, the main stirring paddle 10 is connected to the connecting turntable 9 through a connecting bushing 25 and a limit clamping block 26. The main stirring paddle 10 is fixedly connected to the cylindrical outer wall of the connecting bushing 25. The limit clamping block 26 is fixedly connected to one end of the connecting bushing 25 close to the connecting turntable 9 and is located at one end of the main stirring paddle 10 close to the connecting turntable 9. A plurality of limit slots 27 are formed inside the outer side of the end of the connecting turntable 9 far from the connecting seat 8, and the plurality of limit slots 27 are respectively located on the side of the plurality of connecting jacks 18 far from the connecting seat 8. The limit clamping block 26 is connected to the connecting turntable 9 by being clamped inside the limit slot 27. The connecting bushing 25 and the limit clamping block 26 are both penetrated by a fixing bolt 28 from front to back. One end of the fixing bolt 28 close to the connecting turntable 9 is threadedly connected to the center of the inner side of one end of the limit slot 27 close to the connecting jack 18 and penetrates through the connecting jack 18 and the connecting rod sleeve 19. Since the main stirring paddle 10 is arc-shaped and is fixedly connected to one end of the connecting bushing 25 close to the center of the connecting turntable 9, and the connecting bushing 25 can limit the arc direction of the main stirring paddle 10 through the limit clamping block 26 and the limit slot 27 and fix the position through the fixing bolt 28, the plurality of main stirring paddles 10 can be fixed to and removed from the connecting turntable 9 through the connecting bushing 25 and the limit clamping block 26, so that the plurality of main stirring paddles 10 can be added and reduced more conveniently. Moreover, the arc-shaped main stirring paddle 10 can rotate around the central axis of the connecting turntable 9 through the reaction force of the material, thereby driving the connecting turntable 9 to rotate and simultaneously locally stirring the material. At the same time, the plurality of main stirring paddles 10 and the plurality of connecting rod sleeves 19 can be fixed and removed simultaneously, so that the main stirring paddles 10 and the connecting rod sleeves 19 can be added and reduced simultaneously, making the installation and removal of the main stirring paddles 10 and the connecting rod sleeves 19 more convenient and improving the installation and removal efficiency.

[0044] Preferably, a limit rotating hole 29 is formed inside the center of the end of the connecting seat 8 far from the connecting collar 7.
