Description

Technical Field

[0001] This utility model relates to the field of vertical shaft mixing plant technology, and in particular to a mixing system for a vertical shaft mixing plant. Background Technology

[0002] Compared to traditional horizontal mixing plants, vertical shaft mixing plants have a more stable structure and a longer service life. However, existing vertical shaft mixing plants 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, the 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 slowly, resulting in poor mixing effect. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a mixing system for a vertical shaft mixing plant, which effectively solves the problem of slow rotation speed of the mixing rod itself.

[0004] The technical solution to the technical problem is as follows: a mixing system for a vertical shaft mixing plant, including a shell, a gear ring fixedly installed inside the shell, a sun gear and a planet carrier rotatably installed at the center of the gear ring, planet gears meshing with the sun gear rotatably installed on the planet carrier, the gear ring meshing with the planet gears, a first motor driving the sun gear installed at the top of the shell, a turntable rotatably installed at the bottom of the planet gears, multiple mixing rods extending from the bottom of the turntable, a first gear connected to the bottom of the multiple mixing rods, a second gear meshing with the first gear rotatably installed at the bottom of the shell, a second motor driving the second gear installed at the bottom of the shell, the speed of the first gear is controlled by the speed regulation of the second motor, that is, the speed of the multiple mixing rods on the turntable is controlled by the second motor.

[0005] Preferably, four planetary gears are evenly distributed on the outer side of the planet carrier.

[0006] Preferably, the bottom of the housing is provided with multiple support legs.

[0007] Preferably, four stirring rods are evenly distributed on the turntable.

[0008] This utility model has a simple and ingenious structure and is easy to use. By setting two sets of drive devices to control the rotation speed of the planetary gear and the stirring rod respectively, the revolution and rotation speed of the stirring rod can be adjusted separately, thereby quickly completing the stirring of materials.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 5 It is known that a mixing system for a vertical shaft mixing plant includes a housing 1. A gear ring 2 is fixedly installed inside the housing 1. A sun gear 3 and a planetary carrier 4 are rotatably installed at the center of the gear ring 2. Planetary gears 5 that mesh with the sun gear 3 are rotatably installed on the planetary carrier 4. The gear ring 2 meshes with the planetary gears 5. A first motor 6 that drives the sun gear 3 is installed at the top of the housing 1. A turntable 7 is rotatably installed at the bottom of the planetary gears 5. Multiple mixing rods 8 extend from the bottom of the turntable. The bottom of the multiple mixing rods 8 is connected to a first gear 9. A second gear 10 that meshes with the first gear 9 is rotatably installed at the bottom of the housing 1. A second motor 11 that drives the second gear 10 is installed at the bottom of the housing 1. The speed of the first gear 9 is controlled by the speed regulation of the second motor 11. That is, the speed of the multiple mixing rods 8 on the turntable 7 is controlled by the second motor 11.

[0016] In practical use, this utility model

[0017] When the material is put into the shell 1 and the equipment is started, the first motor 6 rotates, which drives the sun gear 3 to rotate. The sun gear 3 drives multiple planetary gears 5 to rotate around the sun gear 3, which in turn drives the stirring rods 8 on the turntable 7 to revolve. At the same time, the second gear 10 rotates under the action of the second motor 11. The first gear 9 meshes with the second gear 10, and the multiple stirring rods 8 on the first gear 9 rotate on their own axis, which increases the relative speed between the stirring rods 8 and the material, which helps to accelerate the mixing speed of the material and improve the mixing efficiency.

[0018] Four planetary gears 5 are evenly distributed on the outer side of the planetary carrier 4. The four planetary gears 5 make the force on the circumference of the sun gear 3 uniform and less prone to damage. At the same time, increasing the number of stirring rods 8 at the bottom of the planetary gears 5 helps to improve the stirring speed.

[0019] The bottom of the housing 1 is provided with multiple support legs 12, and the support legs 12 are equipped with shock-absorbing structures to prevent damage to the equipment, while also lifting the housing 1 off the ground to facilitate the placement of the second motor 11.

[0020] Four stirring rods 8 are evenly distributed on the turntable 7. The multiple stirring rods 8 enable the material to be stirred faster during rotation, thereby improving stirring efficiency.

[0021] The housing 1 has an inlet and an outlet on its side. The inlet is located below the turntable 7. The material height inside the housing 1 does not exceed the turntable 7 to avoid damage to the transmission structure above.

[0022] The first gear 9 and the second gear 10 can be fitted with covers to protect the gear transmission structure and prevent materials from entering and affecting the transmission.

[0023] Compared with the prior art, this invention has the following advantages: the stirring rod can simultaneously achieve revolution and rotation, which increases the relative speed difference between the stirring rod and the material, thereby improving the stirring efficiency.
