The number of plies is no less than two layers, is covered with hole on blade 310 and is greater than rice husk particle, and when stirring allows rice husk particle to pass through.
The working principle of the utility model is due to being equipped with cover board inside reacting tank body, which only allows acid solution logical
It crosses, rice husk particle is not allowed to pass through, cause rice husk particle that cannot be suspended on acid solution face, it is ensured that rice husk is complete in reaction process
It is immersed in inside acid solution；Furthermore by installing blade on agitating paddle, rice husk particle can be made to pass through, reduce whipping process
Resistance improves the uniformity of stirring；In short, improving acidification efficiency on the whole by installation cover board and the agitating paddle of blade
And effect.
Operating procedure is as follows: first closing valve, opens feeding port, removes cover board hook, through feeding port in reacting tank body
Rice husk is launched, is fed intake and is finished pull-up and hang up properly cover board hook；Then by acid inlet tube be added needed for acid, institute into acid measure to soak
No cover board, charging finishes closing feeding port；Then starting stirring motor drives agitating paddle to be stirred, then opens steam heating
Pipe, steam enter reactor tank and heat to system；The vapor and acid evaporated in reaction process can pass through the cooling tube that flows back
Reactor tank is flow back into after condensing；End of reaction opens outlet valve discharging.
The utility model has the advantages that rice husk can be made to be fully immersed in acid solution during the reaction, it is ensured that rice husk and acid solution
It comes into full contact with, need to increase additional stirring power, the efficiency of acidification reaction can be greatly improved.
