Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a centrifugal mixing device for materials. Background Technology

[0002] The working principle of a centrifugal mixer is mainly based on the centrifugal force generated by high-speed rotation. This force causes the material to move at high speed along the inner wall of the container or on specific mixing components, thus achieving uniform mixing. The specific process mainly includes mixing and mass transfer: In the centrifugal mixer, the material enters the high-speed rotating drum or impeller area and is sheared and dispersed into tiny particles or droplets, allowing different phases to come into full contact, thereby achieving mass transfer. Factors such as mixing intensity, contact time, temperature, and concentration difference affect the mass transfer effect.

[0003] Chinese utility model patent CN216935703U discloses a centrifugal mixer, including a support base, a material hopper mounted on the support base, and a mixing mechanism. The mixing mechanism includes a drive shaft rotatably mounted on the support base and a mixing shaft disposed within the material hopper; the mixing shaft is located on one side of the drive shaft. The mixing mechanism also includes a transmission unit for driving the mixing shaft to move around the drive shaft, with the input end of the transmission unit connected to the drive shaft and the output end of the transmission unit connected to the mixing shaft. The drive shaft drives the mixing shaft to revolve along the axis of the drive shaft through the transmission unit.

[0004] Based on the above technical features, the problem is that the stirring rods in existing centrifugal mixers are generally only located within their respective stirring layers to stir the materials. As a result, the materials between two adjacent stirring rod layers are difficult for the stirring rods to reach, leading to poor mixing quality and low efficiency.

[0005] Therefore, it is necessary to solve the above problems by using a centrifugal mixing device for materials. Utility Model Content

[0024] A first linkage is provided between the rotating plate 6 and the inner wall of the mixing tank 1. The first linkage is in transmission cooperation with two rotating shafts 9. The first linkage is used to drive the rotating shafts 9 to rotate.

[0025] Specifically, the first linkage includes a gear 12 and an internal gear ring 13. The internal gear ring 13 is sleeved on the outside of the connecting shaft 5 and fixedly connected to the inner wall of the mixing tank 1. A gear 12 is sleeved on the outside of each rotating shaft 9, and the gear 12 is rotatably connected to the rotating plate 6. A transmission ring 7 is slidably sleeved on each rotating shaft 9, and the transmission ring 7 and the gear 12 located on the same rotating shaft 9 are fixedly connected.

[0026] Two through holes are made vertically on the rotating plate 6, and the two through holes correspond one-to-one with two rotating shafts 9. Both rotating shafts 9 pass through the corresponding through holes. A connecting ring is fitted on each rotating shaft 9, and each connecting ring is rotatably installed in the through hole through which the corresponding rotating shaft 9 passes.

[0027] The connecting ring is located between the transmission ring 7 and the gear 12 on the corresponding rotating shaft 9, and the connecting ring is fixedly connected to the transmission ring 7 and the gear 12 on the corresponding rotating shaft 9.

[0028] A transmission block 8 is fixedly installed on the inner wall of each transmission ring 7, and a transmission groove 10 is opened along the axial direction on each rotating shaft 9. The transmission block 8 is located in the corresponding transmission groove 10 and is in a limiting sliding fit with the transmission groove 10.

Both the feed inlet 2 and the discharge outlet 3 are equipped with matching control valves. This technology is existing technology and will not be described in detail here.

[0034] Next, motor 4 is started. The output shaft of motor 4 drives the connecting shaft 5 to rotate, and the connecting shaft 5 drives the rotating plate 6 to rotate. The rotating plate 6 drives the two rotating shafts 9 to revolve around the connecting shaft 5, and at the same time, the rotating plate 6 drives the two gears 12 to revolve around the connecting shaft 5. Since the two gears 12 are meshed with the internal gear ring 13, both gears 12 drive the transmission ring 7 to rotate through the corresponding connecting ring, and the two transmission rings 7 drive the rotating shaft 9 to rotate through the corresponding transmission block 8.

[0035] When the two rotating shafts 9 rotate, they drive the two transmission shafts 14 to rotate. When the two transmission shafts 14 rotate, the two push rods 17 push the two transmission shafts 14 to move up and down through the corresponding wave grooves 15, and the two transmission shafts 14 drive the corresponding rotating shafts 9 to move up and down.

[0036] In summary, the two rotating shafts 9 revolve around the connecting shaft 5 while simultaneously rotating on their own axes, and also reciprocate up-and-down movement while rotating on their own axes. Thus, the stirring rods 11 on the two rotating shafts 9 act as impellers in this centrifugal mixing device, shearing and dispersing the material into tiny particles or droplets. During this process, the stirring rods 11 can mix and stir materials in different layers.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
