The air outlet pipe 2 is used to discharge the gas in the storage tank 1 to maintain the internal air pressure stable.

The sealing block 14 gradually breaks away from the resistance sealing state with the inner ring of the sealing tube 15 and the inner ring of the buffer tube 18, so that the sealing tube 15 and the buffer tube 18 are internally connected, preparing for material discharge. When the sealing block 14 moves into place and the material channel is opened, the magnesium hydroxide flame retardant in the storage tank 1 will enter the sealing tube 15 through the first discharge port 11 at the bottom under the action of its own gravity, and then flow into The buffer tube 18, after being buffered in the buffer tube 18, enters the discharge pipe 9 from the second discharge port 17 opened on its circumferential surface, and is finally discharged to the external collection device through the discharge pipe 9 to complete the discharge operation.
