Plate shape into raw material convolution groove turn to, formed rotary current, then press close to driving shaft pilot sleeve to raw material pulping chamber arc end socket flowing turn
For the preceding swash of wave, circulated so as to be formed in raw material pulping intracavitary；
(2) the pulping knife of pulping device, to pressing close to driving shaft pilot sleeve in circulating to raw material pulping in high-speed rotation
Raw material material liquid mixture in the preceding swash of wave of chamber arc end socket flowing carries out continuous pulping processing, and it is broken to be less than raw material for size after processing
The raw material slurry for starching the pulping tap of cavity outer wall is discharged raw material pulping chamber during circulating, and size is arranged more than pulping
The raw material to portal then remain in raw material pulping chamber be performed circulation pulping processing be progressively processed to size less than pulping discharge
Hole forms disturbance so as to discharge raw material pulping chamber, to the liquid level outside raw material pulping chamber, and liquid levels layer material residue is rolled into a ball and crusted
Form strong impact；
(3) the raw material convolution groove steering that the material of middle raw material pulping intracavitary is formed via arc striker plate is circulated, then is pressed close to
Driving shaft pilot sleeve switchs to the preceding swash of wave to the flowing of raw material pulping chamber arc seal head end, the trend of preshoot is formed, so as to drive anaerobism to disappear
Change inside reactor is located at the raw material on material sucking port periphery and feed liquid pours in through material sucking port to raw material pulping intracavitary, forms active suction
The suction stream of effect, material sucking port and anaerobic digestion reaction vessel digestive juice identity distance in running, are in from for 100~300mm
Scum silica frost agglomerate during crust is mixed in feed liquid and sucks raw material pulping chamber by material sucking port, is broken up by pulping device, then by pulping
Tap ejects raw material pulping chamber, so that scum silica frost can not continue to crust.
