[0017] To make the technical problem solved by this utility model clearer, the present utility model is further described below with reference to embodiments and accompanying drawings. The specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0018] like Figures 1 to 2 The image shows an embodiment of the multi-plate convection dispersion device of this utility model. The convection dispersion device includes a rotating shaft 1, a first grid bar 3, a second grid bar 4, a third grid bar 5, a first connecting piece 6, and a second connecting piece 7. The rotating shaft 1 is arranged with the first grid bar 3, the second grid bar 4, and the third grid bar 5 sequentially from top to bottom. Figure 2As shown, the first grid bar 3, the second grid bar 4, and the third grid bar 5 are not parallel to each other. In this embodiment, the angle between any two of the first grid bar 3, the second grid bar 4, and the third grid bar 5 is 30 degrees.

[0020] like Figure 1 As shown, the second grid bar 4 has a shorter length than the third grid bar 5. The upper ends of the first connecting piece 6 and the second connecting piece 7 are connected to the first grid bar 3. The lower end of the first connecting piece 6 is connected to the third grid bar 5. The lower end of the second connecting piece 7 is connected to the second grid bar 4.

[0021] In this embodiment, the convection dispersion device includes a pair of first connecting plates 6 and a pair of second connecting plates 7. The upper and lower ends of each first connecting plate 6 are located on the same side of the rotating shaft 1, and the upper and lower ends of each second connecting plate 7 are also located on the same side of the rotating shaft 1. The pair of first connecting plates 6 and the pair of second connecting plates 7 are arranged in a centrally symmetrical manner.

The convection dispersion device is driven to rotate by an external motor, and the fan blade surface can have pre-reserved flow grooves to facilitate material circulation.

However, it will be apparent that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, the specification and drawings should be considered illustrative rather than restrictive.
