Under cover acid mist outlet, while will also spring back seat 344 and squeezing into the inside of rebound device main body 341, put aside screen resilience, draw having replaced
After conduit 4, the gas in airtube 310 is also emptied, and frizzen 39 resets, and electromagnet 36 is re-energised, and push button 342 is pushed to exist
Seat 344 is sprung back under the promotion of air pressure to pop up, and isolation board 35 is bounced, and being magnetically attracted for isolation board 35 is fitted in connection again
On the tube wall of pipeline 32, acid mist can be inhibited to continue to spread, and carry out mentioning for piping foundation effectively when acid mist is revealed
It wakes up, the environment that surrounding is effectively protected is not destroyed by acid mist.
A kind of acid mist of the present invention reveals the rare earth extraction equipment remedied in time, and during molten using acid, hydrochloric acid is generated
Acid mist it is upward on wave, enter guiding tube 4 in device 3 from anti-let out, be finally discharged into deacidification device from guiding tube 4 from carrying out
Reason, while acid mist also can constantly corrode 41 inner wall of tube body, so that acid mist will spread system out of interior air flue of the tube body 41
The inside of gas chamber 42 erodes the packing box of citric acid band 43, contacts citric acid outflow with sodium bicarbonate 45, generates a large amount of gas
Body, gas enter in airtube 310, will push frizzen 39 having put aside certain pressure, and gas, which can then be blowed, blows a whistle 33, together
When also power off electromagnet 36, allow isolation board 35 to block the acid mist outlet of the molten tank of acid, guiding tube 4 can be carried out more during this period
It changes, the acid mist avoided is largely revealed, and the environment of surrounding is protected.
A kind of acid mist of the present invention reveals the rare earth extraction equipment remedied in time, downward under change after frizzen 39 is pushed
Mobile triggering normally closed switch 37, powers off electromagnet 36, isolation board 35 can then fall to the right with the influence of center of gravity, acid mist is gone out
Mouth blocks, while rebound seat 344 also being squeezed into the inside of rebound device main body 341.
A kind of acid mist of the present invention reveals the rare earth extraction equipment remedied in time, is driven into rebound device main body in rebound seat 344
Behind 341 inside, card ball 343 is caught in card slot 3443, and mobile jib 3442 is limited, and puts aside the screen resilience of spring 345, together
When mobile jib 3442 air flue of rebound device main body 341 is blocked, when triggering push button 342, air pressure can be pushed into mobile jib 3442
Intracavity space pushes card ball 343 open, springs back it, by the upward thruster of isolation board 35, when isolation board 35 was opened to eminence,
The electromagnet 36 that will be re-energised attracts.
