Application filed March 5, 1928. 86118.1 No. 259,085. I
My invention relates to the art of paper making and particularly to means for agitating paper pulp.
In the development of the art it has been found possible to greatly increase the capacity of a given equipment b increas ng the density (or, in other wor s, lessening the fluidity) of the pulp during its treatment preceding delivery to the Fourdriniers. While in the old practice a 2 pulp was considered proper and of the maximum density possible, it is now common to deal with 6% solutions, with correspondingly increased production capacity.
However, many difficult problems are encountered in handling pulp of this density due to its lack of fluidity and its tendency to mass or cake in the storage or treatment tanks and containers. This tendency is 1nherent in the nature of the material under treatment due to its fibrous character and to the physical law of attraction of sol ds. The liquid within which the sollds are carried serves merely as a supporting medium therefor and facilitates rather than hinders the massing and intertwining of the fibers.
To avoid massing and stratifying of the pulp in the liquid and to maintain a uniform density throughout the entire body of material it must be kept in motion and the motion producing means should have a tendency to break up and tear apart any large or small masses of pulp. In the old practice the mixture was kept in motion by means of paddles or impellers in this tank, but this apparatus had very little tendency to break up masses of pulp, and was wholly lneiiective with stock of increased density. Furthermore, such apparatus required an outlay of power not commensurate with the results secured.
The tanks, chests or containers which are in place and must be utilized for the new plan of operation are of many and varied forms, all of great size, some narrow and of great length, some deep and some round. The problem has been, therefore, to provide means applicable to these various forms of tanks that would insure effective circulation, the breaking up of pulp masses and the maintenance at all times of a proper consistency throughout the whole volume of material, with a minimum of power expend1- ture.
My invention will be more readily understood by reference to drawing, in which- Fig. 1 is a plan view of an agitator arrapiged in accordance with my invention, an
Fig. 2 is a longitudinal sectional view on the line 22 of Fig. 1.
In the drawings I have illustrated a substantially square tank of relatively great size and have provided means for adequate agitation and circulation of liquid without the use of any internal battles or division walls. The tank comprises side walls 10, 11 and end walls-12, 13. Three pumps 14, 15, 16 are positioned outside of the end Wall 13 and are operated by suitable motors. Each pump has a plurality of inlet ipes 17 communicating with the interior 0 the tank through the end wall at substantially the level of the floor. The material received through these pipes passes through the screw pump and is discharged upwardly through the pipe 18 and thence horizontally through the pipe 19 to the far end of the tank where the pipe 19 terminates in a T, 20, and a nozzle 21. Thus the entire body of material within the tank is agitated and kept in constant circulation by means of the pumps and the delivery pipes shown. This design is particularly applicable to large tanks in which division walls are undesirable.
I claim:
1. In combination, a substantially square tank, a plurality of pumps each pump' having a plurality of inlet connections with a low level of said tank, and a discharge delivery pipe connected to each pump and extending horizontally within said tank to a point near the far end thereof.
2. In combination, a substantially square the accompanying tank, a plurality of pumps each pump havlivery pipe connected to each pump and ex- 1 tending horizontally within said tank to a point near the far end thereof, said discharge pipes terminating in a plurality of the pump and extending longitudinally nozzles arranged to deliver material in opwithin the chest to a oint near the far end posite directions. of the chest, said pipe terminating in a 10 4. In combination, a chest, a plurality of plurality of oppositely directed outlets. 5 umps located exteriorly thereof, each pump In testimony whereof I have afiixed my having an inlet at substantially the level of signature. the chest floor, a delivery pipe connected to JOSEPH E. BOND.
