In use, the catalyst powder of the PIR material is added into the storage frame box 11, and the speed regulating motor 13 is started to drive The blanking roller 12 rotates in the material storage frame 11. When the blanking trough 14 on the blanking roller 12 rotates to the upper part, the PIR material catalyst powder falls into the blanking trough 14 of the blanking roller 12. When the blanking roller 12 rotates, the blanking trough 14 on the blanking roller 12 rotates to the lower part, and the blanking trough 14 in the blanking roller 12 is tilted downward and falls into the blanking frame 15. Then, the PIR material catalyst powder is guided to the transport pipe 22 through the collecting hopper 21. The high-pressure gas is introduced into the air inlet pipe 25 on the transport pipe 22. The high-pressure gas blows the PIR material catalyst powder in the transport pipe 22 to flow and transport it to In the microchamber high-pressure mixer, the speed regulating motor 13 is used to adjust the speed to control the speed of the blanking roller 12, thereby controlling the falling rate and amount of the PIR material catalyst powder.

The baffle 284 blocks the through-slot plate 282 to prevent the air from carrying the PIR material catalyst powder back to the collecting hopper 21. When the air pressure in the transport pipe 22 is reduced, the upward slide bar 283 is affected by the deformation pressure of the spring 285, thereby pushing the baffle 284 downward, thereby facilitating the PIR material catalyst powder to fall through the through-slot plate 282 and enter the transport pipe 22.
[0027] Working principle: During use, PIR material catalyst powder is added into the storage frame box 11, and the speed regulating motor 13 is started to drive the blanking roller 12 to rotate in the storage frame box 11. When the blanking trough 14 on the blanking roller 12 rotates to the upper part, the PIR material catalyst powder falls into the blanking trough 14 of the blanking roller 12. When the blanking roller 12 rotates, the blanking trough 14 on the blanking roller 12 rotates to the lower part, and the blanking trough 14 in the blanking roller 12 is dumped downward and falls into the blanking frame 15. Then, the PIR material catalyst powder is guided to the transport pipe 22 through the collecting hopper 21, and high-pressure gas is introduced into the air inlet pipe 25 on the transport pipe 22.
