The scattered dust is sucked through the dust suction port 21, and enters the dust box 31 through the connecting cavity 22 and the dust suction main pipe 32. The dust in the dust collecting hood 113 enters the dust box 31 through the dust branch pipe 33 and the dust suction main pipe 32.

[0067] Reference Figure 1 and Figure 2 In the present embodiment, the height of the dust shield frame 2 is higher than the height when the upper feeding seat 11 and the lower feeding seat 12 are separated, so that during the feeding process, the dust shield frame 2 can effectively block the dust, further effectively absorb the dust, and optimize the working environment of the staff; when feeding materials, the overhead crane can be controlled by the PLC system, and the bag opening for placing the materials can be aligned with the upper feeding port 111 to complete continuous feeding.

[0068] The structures of the upper feeding seat 11 and the lower feeding seat 12 can be appropriately adjusted according to the position of the feed port of the reactor, so that the upper feeding seat 11 and the lower feeding seat 12 are finally arranged vertically for easy use.

[0069] Working principle: When in use, first connect the upper feeding seat 11 and the lower feeding seat 12 through the telescopic member 13, and the upper feeding seat 11 and the lower feeding seat 12 are sealed by the groove 114 and the convex strip 124. When the telescopic member 13 drives the upper feeding seat 11 to descend, the first connecting rod 143 and the second connecting rod 144 drive the closing plate 142 to move, thereby opening the inside of the lower guide pipe 122, and then the material is put in through the upper feeding port 111. The dust generated during feeding is blocked by the arc baffle 115, and the dispersion of the dust is slowed down, and then The dust is then dispersed from the arc baffle 115, and the dust collecting hood 113 can effectively prevent the dust from rebounding into the air, and prevent the dust from floating out from the upper guide pipe 112 as much as possible. At the same time, the fan 34 is started, and the dispersed dust is sucked through the dust suction port 21, and enters the dust suction box 31 through the connecting cavity 22 and the dust suction main pipe 32. The dust in the dust collecting hood 113 enters the dust suction box 31 through the dust suction branch pipe 33 and the dust suction main pipe 32. Then, the material enters the reactor from the dust collecting hood 113 through the lower feeding port 121, the lower guide pipe 122 and the base 123;

[0070] When the feeding is completed, in order to prevent the dust in the reactor from rebounding back to the upper feeding port 111 and drifting out from under the cover of the arc baffle 115, the upper feeding seat 11 is separated from the lower feeding seat 12 by the telescopic member 13. In the process of the telescopic member 13 driving the upper feeding seat 11 to rise, the first connecting rod 143 and the second connecting rod 144 drive the closing plate 142 to move, thereby closing the inside of the lower feed guide pipe 122, so that the dust cannot rebound. When the upper feeding seat 11 is separated from the lower feeding seat 12, the dust drifting out from between the upper feeding seat 11 and the lower feeding seat 12 is blocked by the dust shield frame 2 and sucked out by the fan 34, thereby reducing the dispersion of dust and optimizing the working environment of the staff.
