Leaf, agitating shaft outer wall are equipped with air inlet pipe, and air inlet pipe both ends are respectively equipped with air inlet and gas outlet, and air inlet is located in the autoclave body
More than the liquid level of raw material, together with gas outlet is fitted closely with the one side of the blade.
Preferably, autoclave body periphery is equipped with steam jacket, and steam jacket upper end is equipped with steam inlet, and lower end goes out equipped with condensed water
Mouthful.
Preferably, steam jacket peripheral circumferential is uniformly provided with 3 bearings.
Preferably, the thermometer being deep into from kettle cover inside autoclave body is equipped on the right side of autoclave body.
Preferably, thermometer periphery is equipped with temperature-measuring casing, and temperature-measuring casing top is equipped with thermometric fixing device, and thermometric fixes dress
It puts and is arranged on kettle cover.
Preferably, air inlet and gas outlet are pressed into bell shape.
Preferably, retarder is equipped with below stirring motor, rack is equipped with below blender.
Preferably, blade quantity can be set to 2,4,6,8, and air inlet pipe quantity is identical with blade quantity, and air inlet pipe end goes out
The direction of gas port can arbitrarily be adjusted according to the angle of inclination of blade.
The utility model is simple in structure, and cost is relatively low, and the air inlet of air inlet pipe and gas outlet are pressed into horn mouth
To increase the output of gas, the liquid of surrounding is constantly arranged by blade during blender high speed rotation makes its back side be formed very
Sky, at this time the gas outlet of back side gas more than liquid level is drawn into below liquid level under the action of pressure differential, the gas sucked in
Body is broken up rapidly under the action of blade so that and gas comes into full contact with liquid, so as to increase the contact area of gas and liquid,
It is energy saving, practical and convenient.
