[0026] In the embodiment, preferably, a dredging member 200 for dredging the scattering hole 103 is arranged in the scattering plate body 100, so that the material is not clamped in the scattering hole 103 on the premise of further scattering of the material, the dredging member 200 comprises a wedge-shaped plate 201 horizontally installed in the retention cavity 102, and a dredging rod 202 is arranged on the upper surface of the wedge-shaped plate 201 and corresponds to the position of the scattering hole 103.

[0027] In the embodiment, preferably, a plurality of groups of mounting members are arranged between the lower surface of the wedge-shaped plate 201 and the inner wall of the retention cavity 102, each group of mounting members comprises two circular plates 203, and a reset member 204 is arranged between the two circular plates 203, the reset member 204 can be elastically deformed after the wedge-shaped plate 201 is impacted by the gas, so as to drive the wedge-shaped plate 201 and the dredging rod 202 to move up and down and push the material clamped in the scattering hole 103 outward.

[0028] In the embodiment, preferably, the peripheral surface of the wedge-shaped plate 201 is attached to the inner wall of the retention cavity 102, and the two cooperate to guide the up-and-down movement of the wedge-shaped plate 201.

[0029] In the embodiment, preferably, the upper surface of the wedge-shaped plate 201 is an inclined surface, and the left end of the wedge-shaped plate 201 is lower than the right end, so as to facilitate the cooperation with the air inlet 101, the wedge-shaped plate 201 is a right trapezoid in the main view, the upper surface is an inclined surface, and the lower surface is flat, facilitating the installation of the circular plate 203 and the reset member 204.

[0030] In this embodiment, preferably, the left end of the wedge-shaped plate 201 is flush with the lowermost part of the air inlet 101, so that the gas entering from the air inlet 101 can flow along the inclined surface of the wedge-shaped plate 201 in the space above, and the circulation of the gas in the space above can press the wedge-shaped plate 201 to move.

[0031] In this embodiment, preferably, the upper ends of the plurality of dredging rods 202 are flush, and the dredging rods 202 are located at the center of the dispersing hole 103, so that the large material particles can not be stuck in the dispersing hole 103, and the continuous flow of the material is ensured.

[0032] In this embodiment, preferably, a space is left between the dredging rod 202 and the inner wall of the dispersing hole 103, and the diameter of the dredging rod 202 can be set according to the size of the diameter of the dispersing hole 103, so that the dredging rod 202 can dredge the material in the dispersing hole 103 without blocking the dispersing hole 103, and the flow of the material is facilitated.

[0033] In summary, in use, the dispersing plate body 100 is installed in the V-type powder concentrator, the fan outside the V-type powder concentrator introduces the gas into the air inlet 101, and the gas is circulated and retained in the retention cavity 102, and part of the gas passes through the dispersing hole 103 to form high-speed gas jet, which can quickly disperse the agglomerated material, and the dispersing plate body 100 has increased the ability to disperse the material. Since the high-speed gas jet from the small hole is very fine and has limited carrying capacity, the high-speed gas jet only affects the small particle size material, and does not affect the falling of the large particles. Part of the material is retained in the retention cavity 102 for sufficient dispersion, and is discharged along the space between the dispersing hole 103 and the dredging rod 202, thereby prolonging the retention time of the material and fully dispersing the material. At the same time, the gas entering the retention cavity 102 impacts on the wedge-shaped plate 201, and the force applied by the gas makes the wedge-shaped plate 201 move downward, so that the reset member 204 is in a compressed state, and an opposite compression force is generated. Since the gas enters discontinuously, the wedge-shaped plate 201 moves up and down in cooperation with the reset member 204, thereby driving the dredging rod 202 to move upward, and pushing the particles stuck in the dispersing hole 103 outward, so that the dispersing hole 103 is not easily blocked, the continuous dispersion of the material is ensured, and the gas introduced into the retention cavity 102 can be at a constant rate or an irregular rate. The irregular gas rate passing through the dispersing hole 103 can form irregular dispersion of the agglomerated material, thereby increasing the convenience and fullness of the material dispersion.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical method of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical method of the present application.
