APPARATUS FOR TREATMENT OF PAPER PULP AND OTHER FIIBROUS MATERIALS.
' To all whom it may concern.-
paratus for treatment of paper pulp and other fibrous materials.
An, apparatus accordmg to the invention is adapted to effect the separation or hydration of the materialand comprises a rotary spiked drum or brush cooperating with a stationary concave grooved member.
Figure 1 of the. accompanying drawings is a vertical section illustrating diagramma'tically apparatus according to the invention. Fig. 2 is a fragmentary elevation to a larger scale and Fig. 3 a developed view showing the spiked face of the drum or brush, which may be coarser or finerin itch according to the degree of fineness 0? detail views showing the form of spike employed. Fig. 6 is a developed view showing.
the formation of the grooves in the concave members. Fig. 7 shows the adaptation of the improved apparatus-as an adjunct to a Hollander beater.
The same reference numerals denote similar parts in the several views.
As shown, the improved apparatus comprises a spiked drum .or brushl revolving at 'high speed, and provided with a number of projecting staggered rows of outwardl spikes 2 having'chisel edges isposed parthe 1 material to be treated. Figs. 4: and 5 are- Speciflcation of Letters Patent. Patented Dec, 10 1918, Application filed. February 16, 1918. Serial No. 217,698.
Fig. 1 shows the drum or brush 1 as mounted within a casing 3 having an inlet 4 and outlet 5 the axis of the drum being horizontal.
Within the casing .3 spaced slightly from the spiked periphery of the drum or brush 1, is a segmental liner member 6 formed with grooves disposed, for example, herring-bone ashion, 2', e., in zi -zag relation to an imaginary line paral el with theaxis of the drum. The liner member 6 is preferably slightly eccentric to the driim or brush 1, or the wall of the casing 3ma.y be concaved and grooved.
The drum or brush 1 and the liner member 6 may be adjustable toward and away from one another.
What we claim 1s:
1. Appa-ratus'for the treatment of paper pulp and other fibrous material in the wet state, comprising a rotary member provided with staggered rows of spikes having chisel posed parallel with the axis of rotation, and
a stationary concave cooperating with said rotary member, said concave having grooves of herring-bone formation. 1
In testimony whereof we have signed our names to this specification in the presenceof two subscribing witnesses.
