Description

Technical Field

[0001] This utility model relates to the field of vertical shaft mixing plant technology, and in particular to an ultra-high speed variable speed vertical shaft planetary mixer. Background Technology

[0002] Compared to traditional horizontal mixers, vertical shaft mixers have a more stable structure and a longer service life. However, existing vertical shaft mixers have the following drawbacks: the mixing rod is fixedly connected to the planetary gears. When the planetary gears rotate, they drive the mixing rods to rotate and achieve mixing. Due to the limitations of the planetary gear structure, a sun gear is generally used as the driving component to drive the planetary gears to rotate around the center of rotation of the sun gear. However, the mixing rods themselves rotate at a relatively slow speed, resulting in poor mixing effect. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides an ultra-high speed variable speed vertical shaft planetary mixer, which effectively solves the problem of slow rotation speed of the mixing rod itself.

[0004] The technical solution to the technical problem is: an ultra-high speed variable speed vertical shaft planetary mixer, including a shell, a rotating ring rotatably arranged inside the shell, the rotating ring having an "H" shaped structure, a sun gear and a planet carrier rotatably arranged at the center of the rotating ring, planet gears meshing with the sun gear rotatably arranged on the planet carrier, a stirring shaft rotatably arranged at the bottom of the rotating ring and the planet gears, multiple stirring rods extending out of the stirring shaft, a first gear ring extending out of the shell and meshing with the stirring shaft, a first gear meshing with the first gear ring on the stirring shaft, and the first gear meshing with the first gear ring when the planet gears rotate, causing the stirring shaft to rotate.

[0005] Preferably, the bottom of the rotating ring is provided with a second gear ring that meshes with the planetary gear, the upper part of the rotating ring is provided with a third gear ring, the upper end of the sun gear is provided with a second gear, and a third gear is slidably arranged on the housing. The third gear is driven by a motor. After the third gear slides, the pump meshes with the second gear or the third gear ring, forming a structure in which the motor drives the sun gear or the rotating ring to rotate.

[0006] Preferably, the inner side of the housing has a protrusion, and the outer side of the rotating ring has a groove. The protrusion and the groove cooperate to form a structure in which the housing and the rotating ring are rotatably connected.

[0007] Preferably, four planetary gears are evenly distributed on the outer side of the planet carrier.

[0008] Preferably, a groove is provided on the upper part of the housing, the rotating shaft of the third gear slides in the groove, a bracket is slidably provided on the upper part of the housing, the motor is fixed on the upper part of the bracket, and a hydraulic cylinder connected to the motor is provided on the upper part of the housing.

[0009] Preferably, the housing is provided with a first limiting rod that cooperates with the second gear and a second limiting rod that cooperates with the third gear ring. Connecting plates extend from both sides of the bracket, and inclined grooves are provided on the connecting plates. The upper end of the first limiting rod or the second limiting rod is provided with a pin inserted into the inclined groove, thus forming a structure in which the movement of the bracket drives the first limiting rod and the second limiting rod to rise and fall.

[0010] This utility model has a simple and ingenious structure and is easy to use. It meshes the stirring shaft with the housing for transmission, which increases the rotational speed of the stirring shaft when the planetary gear drives the stirring shaft to rotate, thereby improving the stirring speed. Furthermore, by changing the drive components, the output speed of the stirring shaft is increased, achieving ultra-high-speed variable-speed stirring. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 4 It is known that an ultra-high speed variable speed vertical shaft planetary mixer includes a shell 1, a rotating ring 2 rotatably arranged inside the shell 1, the rotating ring 2 having an "H" shaped structure, a sun gear 3 and a planet carrier 4 rotatably arranged at the center of the rotating ring 2, planet gears 5 meshing with the sun gear 3 rotatably arranged on the planet carrier 4, four planet gears 5 evenly distributed on the outer side of the planet carrier 4, the bottom of the rotating ring 2 meshing with the planet gears 5, a stirring shaft 6 rotatably arranged at the bottom of the planet gears 5, multiple stirring rods 7 extending out from the outer side of the stirring shaft 6, a first gear ring 8 meshing with the stirring shaft 6 extending out from the shell 1, and a first gear 9 meshing with the first gear ring 8 on the stirring shaft 6. When the planet gears 5 rotate, the first gear 9 meshes with the first gear ring 8, causing the stirring shaft 6 to rotate.

[0017] In practical use, this utility model

[0018] The planetary gear 5 rotates around the sun gear 3 under the drive of the drive device. When the planetary gear 5 rotates, the stirring shaft 6 at the bottom of the planetary gear 5 drives the first gear 9 to rotate within the first gear ring 8, thereby realizing the rotation of the stirring shaft 6. During the high-speed rotation of the planetary gear 5, the stirring shaft 6 itself rotates even faster, realizing ultra-high-speed stirring of materials, accelerating the stirring speed of materials, and improving stirring efficiency.

[0019] The shell 1 has a feed inlet on its side, which is located at the bottom of the first gear ring 8. The shell 1 has a discharge outlet at its bottom for discharging the mixed material.

[0020] The bottom of the rotating ring 2 is provided with a second gear ring 10 that meshes with the planetary gear 5, the upper part of the rotating ring 2 is provided with a third gear ring 11, the upper end of the sun gear 3 is provided with a second gear 12, and a third gear 13 is slidably arranged on the housing 1. The third gear 13 is driven by the motor 14. After the third gear 13 slides, the pump meshes with the second gear 12 or the third gear ring 11, forming a structure in which the motor 14 drives the sun gear 3 or the rotating ring 2 to rotate.

[0021] Before starting the equipment, move the third gear 13 to mesh with the second gear 12 or the third gear ring 11. The motor 14 drives the third gear 13 to rotate, causing the second gear 12 or the third gear ring 11 to rotate. That is, the sun gear 3 or the rotating ring 2 acts as the active component, driving the planetary gear 5 to rotate. The stirring rod 7 is set below the planetary gear 5 to achieve stirring of the material. The stirring speed can be controlled by changing the speed of the motor 14.

[0022] Since the transmission ratio of the planetary gear structure is different when using the sun gear 3 or the rotating ring 2 as the driving component, the transmission ratio between the planetary gear 5 and the motor 14 can be expanded, increasing the range between the maximum and minimum stirring speeds, thereby expanding the application range.

[0023] A protrusion 15 extends from the inner side of the housing 1, and a groove 16 is provided on the outer side of the rotating ring 2. The protrusion 15 and the groove 16 cooperate to form a structure in which the housing 1 and the rotating ring 2 are rotatably connected.

[0024] A slide groove 17 is provided on the top of the housing 1. The rotating shaft of the third gear 13 slides in the slide groove 17. A bracket 18 is slidably provided on the top of the housing 1. The motor 14 is fixed on the top of the bracket 18. A hydraulic cylinder 19 is provided on the top of the housing 1 and connected to it. The hydraulic cylinder 19 drives the bracket 18 to move to realize the meshing of the third gear 13 with the second gear 12 or the third gear ring 11.

[0025] The housing 1 is provided with a first limiting rod 20 that engages with the second gear 12 and a second limiting rod 21 that engages with the third gear ring 11. The bracket 18 has connecting plates 22 extending from both sides. The connecting plates 22 have inclined grooves 23. The upper end of the first limiting rod 20 or the second limiting rod 21 is provided with a pin that is inserted into the inclined groove 23. This forms a structure in which the bracket 18 moves to drive the first limiting rod 20 and the second limiting rod 21 to rise and fall. After the first limiting rod 20 descends, it is inserted into the tooth gap of the second gear 12 to limit the second gear 12. Similarly, after the second limiting rod 21 descends, it can limit the third gear ring 11. That is, when the sun gear 3 is the driving component, the rotating ring 2 is fixed. Similarly, when the rotating ring 2 is the driving component, the sun gear 3 is fixed, thereby fixing the transmission ratio. This allows the planetary gear 5 to rotate under the drive of the motor 14, thereby achieving the mixing of materials.

[0026] The lifting and lowering of the first limiting rod 20 and the second limiting rod 21 are controlled by the inclined groove 23 on the connecting plate 22, which cooperates with the movement of the third gear 13. When the third gear 13 approaches the second gear 12, the first limiting rod 20 moves upward to disengage from the second gear 12, while the second limiting rod 21 moves downward to limit the third gear ring 11. Conversely, when the third gear 13 approaches the third gear ring 11, the first limiting rod 20 moves downward to limit the second gear 12, and the second limiting rod 21 moves upward to disengage from the third gear ring 11, ensuring smooth power transmission and stability of the planetary gear structure.

[0027] Compared with the prior art, this utility model has the following advantages: the motor can drive the sun gear or the rotating ring, thereby changing the transmission ratio of the planetary gear structure, realizing variable speed adjustment, increasing the output speed of the planetary gear, expanding the application range of the mixer, and enabling it to be applied to the mixing of more materials; the mixing shaft rotates with the shell during the rotation of the planetary gear to achieve self-rotation, accelerate the rotation speed of the mixing rod, and improve the mixing efficiency.
