REFINING-AND CIRGULATING DEVICE FOR PAPER s'rocx Fi1ed Aug. 28, 1929 Patented Jan. .26, 1932 UNITED STATES PATENT OFFICE -.t.pp1ioation filed August 28, 1929. Serial No. 388,958.
My invention relates to the treatment of paper stock and particularly to a unit consisting of a tank, pump and heater arranged in a novel manner.
n The partially treated stock known as halfto the et'ficiency of this treating operation by relit till
ducing the power consumption, increasing the capacity and efiectiveness ot the refining device and improving the quality of the fiber that is treated.
ln the apparatus herein described and claimed, 1 utilize a refining and beating device that is specifically claimed in my copending application Serial Number 388,957, filed o'l even date herewith.
in the combination of the devices preferably utilized, it include a tank of sufiicient size to receive a batch of adequate proportion. Means are provided for insuring circulation of the fluid stock, such means ineluding a pump. The intake of the pump is arranged at one side of a bafie in the tank and the outlet at the opposite side and at a difierent level. As a part of the pump unit I provide the heating or refining engine, preferably operated by the pump motor, and on the same shaft, a quantity of the circulated material being drawn into the refining device, suitably treated and directed from that point back into the tank, or after adequate treatment of the entire mass, it may be directed into the stufi' chest.
The invention will be more readily understood by reference to the accompanying drawings, in which Fig. 1 is a plan view of a combination of devices such as contemplated;
Fig. 2 is a longitudinal sectional view on the line 2-2 of Fig. 1 and Fig. 3 is an end view with a part of the refining device broken away to show the internal construction.
in the drawings, 1 have illustrated an oblong tank having a mid-feather or baflle ll extending from one end wall to a point adjacent to the opposite end wall. A screw or centrifugal pump 12 is mounted exterior to the tank, its inlet 13 being open to the space 14 at one side of the baflle 11 while its outlet 15 is open to the space 16 on the opposite side of the battle and at a higher point than the inlet. The floors 17-18 in the tank on the inlet and outlet sides of the baffle are inclined, as shown, to facilitate the flow of material.
A refining device similar in form to a J ordan engine is indicated at 19 consisting of a tapered hollow casing and a plug 20 therein having volute ribs 21 thereon. The plug is fixed to a shaft 22 that operates the screw pump impeller, amotor 23 serving to efl'ect the rotation of the parts. The construction of the refining device is such that it operates as a centrifugal pump with fair efliciency, a fractional portion of the circulated material being drawn into the refiner, properly treated and directed outward through the pipe 24 back into the tank. It may be directed into the space 16 at the discharge side of the pump or into the space 14: on the intake side as indicated at 25 by the dotted lines in Fig. 3. After suitable treatment the necessary valves may be manipulated and the treated material directed away from the outlet through the pipe 26.
I may prefer to operate the apparatus as a continuous process in which case material is constantly or intermittently supplied to the tank through the pipe 9, and the material that passes through the refiner is constantly discharged through the pipe 26. In that case the circulating pump serves to efiectively hydrate the stock and takes the place of the ordinary beater. By maintaining the stock in a thoroughly agitated condition and treating portions thereof in the refiner, I am able to operate the device as a continuous process.
The construction of the refiner is specifically claimed in my copending application heretofore identified, and suchconstruction is not claimed herein. It will be apparent however, that the arrangement of the parts is such that a portion of the circulated batch is directed or drawn into the small end of the refining device due to its location at the outlet from the pump 12. The portion withdrawn and I, the pump,
treated in the refiner is returned to the main batch and the whole mass is progressively treated in that manner. By this method the entire batch is kept in constant circulation to prevent stratification, and treatment may be effected much more efliciently than by the known methods and apparatus.
It is obvious that the arrangement here shown is only illustrative and that variations may be made within the scope of the. appended claims, without departure from the spirit of my invention.
I claim:
1. In combination, a tank, a pump for agitating and circulating half-stuff in the tank, a refining device having its inlet adjacent to the discharge from the pump, whereby a portion only of the circulated material is received into the refining device, and means for discharging all the material from the refiner back into the tank.
2. In combination, a tank for receiving a batch of half-stufi, a pump for constantly circulating the material in the tank, a beater mounted to receive a relatively small proportion of the half-stuff discharged from the pump, and means for discharging all the material from the beater back into the main body of material.
3. In combination, a tank having a baiile, a circulating pump for withdrawing material from one side of the baflle and discharging the same into the tank on the opposite side of the bafiie at a different level, a heater for treating a fractional part of the circulated material, and means for optionally delivering the said fractional part back to the tank or to a point of use.
4:. In combination, a tank having a bafile, a circulating pump for withdrawing material from one side of the bafile and discharging the same into the tank on the opposite side of the bafiie at a different level, a tapered casing, and a tapered plug mounted on the pump shaft and fitting within the casing, the small end of the casing being open to the space at the discharge from the pump, whereby the refining plug, acting as a pump, withdraws for treatment a portion of the material circulated by the pump.
\ 5. In combination, a tank having a baflle, a circulating pump for withdrawing material from one side of the baffle and discharging the same into the tank on the opposite side of the bafile at a different level, a tapered casing, a tapered plug mounted on the pump shaft and fitting within the casing, the small end of the casing being open to the space at the discharge from the pump, whereby the refining plug, acting as a pump, withdraws for treatment a portion of the material circulated by and a pipe at the large end of the casing for delivering material to a desired point. V
6. In combination, means for constantly circulating a batch of paper stock, and means for constantly withdrawing and beating fractional portions of the circulating stock and returning all such beaten portions of the stock to the batch.
7. In combination, means for constantly circulating a batch of paper stock, and means for constantly withdrawing and beating fractional portions of the circulatingstock and returning all such beaten portions of the stock to the batch, the beater acting as a pump for effecting such return.
8. In combination, a tank for half stuff, a circulating and refining unit located exteriorly of and immediately adjacent to said tank, said unit including a pump having an impeller, said pump having inlet and outlet connections to said tank, a refiner such as a Jordan having its small end open to the outlet from said pump, and a motor for operating said refiner and pump.
9. In combination, a tank for half stufit', a circulating and refining unit located exteriorly of and immediately adjacent to said tank, said unit including a pump having an impeller, said pump having inlet and outlet connections to said tank, a refiner such as a Jordan having its small end fitted against the outlet from said pump, and a motor for operating said refiner and pump.
10. In combination, a tank for half stufl', a circulating and refining unit located exteriorly of and immediately adjacent to said tank, said unit including a pump having an impeller, said pump having inlet and outlet connections to said tank, a refiner such as a Jordan having its small end open to the outlet from said pump, a shaft carrying the refiner plug and said impeller, and a single motor for operating said shaft.
In testimony whereof I have afiixed my signature.
JOSEPH E. BOND.
