The shortcoming of the common high-density paste mill of this structure is:
1. because high dense fibrous raw material mobile very poor, feed auger is again concentric with fixing abrasive disc, and before entering defibrination district, plane defibrination, must discongest the district through the feed zone at abrasive disc center with fragmentation earlier with certain gradient, high dense fibrous raw material relies on the brute force of feed auger to push fully could to discongest the district by fragmentation and enters defibrination district, plane, this feeding manner causes high dense fibrous raw material to discongest the district in fragmentation on the one hand easily and stops up, and forms the solid material piece of similar " discus " and can't enter defibrination district, plane; On the other hand, the powerful pushing force of feed auger acts on the Moving plate of rotation, and the rotational resistance of Moving plate and main shaft is strengthened, and refining energy consumption increases greatly, has also increased canonical loading simultaneously, has shortened the life-span of main shaft bearing.
2. owing to adopt stuffing box or mechanical seal between the housing of common high-density paste mill and main shaft, and high dense fibrous raw material is mobile very poor, therefore the grout outlet that is difficult to from the housing of the slurry behind the mill is discharged, even be provided with the pulp blade on Moving plate, the slurry behind the mill still often gets lodged in grout outlet to be difficult to discharge.
(3) summary of the invention
The object of the present invention is to provide a kind of above-mentioned common high-density paste mill shortcoming that can overcome, need not brute force when charging, to push high dense fibrous raw material, charging and pulp not susceptible to plugging; The high concentration refiner of eccentric feeding that the main shaft bearing load is light, bearing life is long, refining energy consumption is lower.
On the basis of above-mentioned prior art, the present invention is achieved in that at first, the rotation abrasive disc of different structure and fixing abrasive disc have been designed, cancel the fragmentation on the abrasive disc and discongested the district, except the Moving plate locking nut installing hole at rotation abrasive disc center and fixedly the charging hole on the abrasive disc, rotate abrasive disc and fixedly the remaining surface of abrasive disc be the flat defibrination flank of tooth; Secondly, the housing drive end bearing bracket and fixedly the charging hole on the abrasive disc be provided with eccentric throw with respect to the center of rotation abrasive disc greater than the charging hole radius, make charging hole aim at the defibrination flank of tooth of rotation abrasive disc, the other equidirectional that rotates with the rotation abrasive disc of charging hole also is provided with an arc groove from depth to shallow on the fixing abrasive disc flank of tooth; The 3rd, cancel and make into the ventilating duct of annular with being positioned at main shaft hermetically-sealed construction on every side on the housing.
(4) description of drawings
The structure of one of high concentration refiner of eccentric feeding embodiment of the present invention is as shown in drawings: be fixed with drive end bearing bracket 2 on housing 4, be fixed with feed auger 1 in the drive end bearing bracket front, be fixed with fixedly abrasive disc 3 in the back of drive end bearing bracket, also be fixed with main shaft and bearing housing 8 on the housing, the front end of main shaft is fixed with Moving plate 6, the Moving plate front is fixed with rotation abrasive disc 5, also is fixed with the outstanding blade 9 of multi-disc at the Moving plate periphery, the refining plate interval governor motion also is installed on main shaft, is provided with annular air channel 7 between main shaft and the housing.
