1 toa method for convertingliquid paper pulp or the like into a consistent suitable for storage, etc., or
into bales for shipment.
i"II1;lthiSllpp1iC8 tlbn I have shown anddescribed apparatus shown in my copending'applicationj-for convertingnli uid paper P P into aconsistent 'suitab e for stor-,
,etc.', or into; bales for shipment, Serial 165,7 74, filed b me on February 4,
ing through the new-manufacturing method, in the present application the claims are directed to my new niethodsteps which are capable of being -carried out by any suitable apparatusfor in any convenient manner.
The particular object of my invention to eliminate the" wet presses, hydrauhc. presses, carts, etc., as well as the enormous manual work involved with the present system forobtainiiig a pulp of consistent form such as would be suitable for storage or for producing bales from the liquid stock. a
With the old system of using the said wet machines so called laps are produced containing about -75% of water. These laps the water pressed out fromthe laps in the hydraulic presses, have then be removed from the laps whereupon thejlatter,after,lf having been reassembled, are sent to the storage or are packed into bales for shipment,
on the baling press which generally is of the same type as the hydraulic dewatering ress,on1y of somewhat lighterconstru'ction.
e wet presses used in that old pulp treat-- ing system, requires new wires and felts rather frequently, which means high maintenance and upkeeping costs; Further the frequent insertion of fresh felt or other of which this app 'cation' forms a Whereasinthe parent application referred? to I have claimed-the apparatus for carry-'2 Serial No. 408,188,
mous floor space.
Accordingto the method of my invention I avoid all these disadvantages by predewaterly into baling presses of the hay press type,
which inturnsurrender the finished bale on a bale conveyor leading to the store house or to the railway car or other shipping contrivance.
' Where-the pulp storage or baling department is at a location distant from the other parts of thepulp manufacturing plant, then the pneumatic handling of the pulp leaving the screw press is of considerable advantage. Therefore'it is further an essential part of my invention, to have the pulp manufacturing plants adapted to such new and improved working conditions. When using my new method of pulp handling, I may connect a special feeding device between the screw press and the air pressure pipe line through whichthe pulp is blown to the storage or baling department. The compressed air is delivered to this piping from a compressor, and 'only a relatively low air pressure of 30 to. 40 'lbs. is required for blowing the pulp over a distance of half a mile and more.
carrying-out my method steps in my new manufacturing plant the feeding equipment may comprise a trough, a hopper, a screw feeder in the cylinder part of the noun) runs runr a coxsrsrnm" mm sorranna' together require much manual work and an expensive installation, occupying an enorof the trou h.
trough, and a pressure chamber into which the screw feeds the moist pulp. The end of the cylindrical part of the trough. into which the feeding screw does not pass, is of conical shape, having its larger end towards the pressure chamber and its smaller end towards the screw. The stock forced through this conical art into the pressure room is sub-- 'ect on e screw side to the pressure produced the action of the screw, on the pressure 0 amber side it is under the pressure prevailing in the air pipe connected to the pressure chamber. The stock forms in the conical art a kind of plug which prevents the stock rom being blown back into the screw room Suitable equipment may also consist in t e arrangement, at the one end of the shaft of the screw towards the pressure chamber of a knife-like tool which scrapes small articles in even quantities from the pulp fe into the pressure chamber. These loosened particles are carried away by the compressed air passing through the pressure chamber and are transported through the adjoining piping to the distribution storage bin, baling press, hopper etc. Thereby the pressure chamber is referably arranged in sucha manner that t e knife itself is almost fully out of the path of the compressed air current and only the pulp to be transported is in this path of the stream of air.
It is further a. part of my invention to counteract a variation in moisture of the pulp to be blown to which purpose the distance between the end of the feeding screw and the knife may be varied; for pulp containing less moisture, the distance is shorter, whereas pulp with a higher moisture content requires a larger distance between the end of screw and the knife, in order to prevent the pressure in the ressure chamber from blowin the stock in t e wron way through the fee g screw instead of bIowing it through the piping.
A mode of carrying out the present invention is shown by way-of example in the accompanying drawings, in whic Figure 1 is a diagrammatic cross section of a pulp treating plant suitable for carryin out my new method; and
iig. 2 shows a lon 'tudinal section of the special pulp feeding evice 6 in larger scale.
In the apparatus illustrated by -way of example in Figure 1, 1 is the screen in which the pulp to be dewatered is freed from coarse particles, etc. The fgood pulp leaves the screen in a dilution 0 1 part 0 solid matter to about 300 parts of water, which latter is partly removed in the decker 2 to a consistency of from 2 to 8% of the pulp. The pulp thus redewatered is collected in a chest 3 and ows from there to the screw press 4, where the final dewatering is taking place. The pulp leaves the screw press 4 with a consistency of 30 to containing to u 45% water, and falls into the special feeding device 6 which leads it into its ressure chamber 7 into which com'presse air is blown through a piping 8, which is connected to the air tank 9. If more than one screw press is bein used then the pulp leaving the presses is co lected in a conveyor 5 and carried by it to the feedinegi air is produc the com resso'r 10, which 18' connected to t e air ta 9 by means of piping 11. To the pressure chamber 7 is connected the ressure piping 12,'through which the pul ed into t e pressure chamber is blown by t e compressed air to either the storage 13, or to the cyclone 14 on the roof of the bahng department. From the cyclone in which the air is se arated fromthe ulp the latter drops into t e bin 15 and is fed om there into the hopper 16 of the baling ress 17. The baling press delivers the pul in bales 18-to aconveyor or the like 19, on w ch the bales are gevices 6. The compressed acked for shi mentif necessary and whic carries them 'rectly into the I frei or e warehouse for storage in case no direct shi ment is intended.
Fi 2 which shows the. feedin device 6 with t e pressure chamber 7 of i 1 in larger scale, 21 desi ates the troug with hopper 22 into whic the ulp is delivered from the screw press 4 of ig. 1.
23 is the feedm screw in the cylindrical part of the trou 24 is the shaft of the screw carried on t e hopper side in a bearing 25 and driven on its free-end through a pulley 26. 27 is the conical part of the trough in which the ulp forms the sealing plug, 28 is the knife astened to the shaft on the ressure chamber side. 29 is the ressure c amber with openings 30 and 31 in it, to which the pi e 8 from the air tank 9 and the pipe 12 ltea1 ing to the storage or cyclone are connec e ht car 20 or, other shipping contrivance Instead of a feeder of the screw type, any
other typeof feeding device such as a piston feeder, etc., and instead of air handling any other system for conveying the pulp can be used without departing from the spirit of my invention.
It is to be understood that I do not limit myself to the precise method steps employed except as indicated in my claims, and it will be obvious to those skilled in the art to which my invention appertains that many forms of apparatus and kinds of equipment may be used to carry out the manufacturing method hereinbefore explained.
I claim:
1. In a method of treating paper pulp stock, first denuding loose paper stock of the greater part of its moisture content, then disintegrating the denuded pulp stock and finally subjecting particles of the pulp. stock at the point of disintegration to the action-of compressed air and conveying the same while in air suspension to a remote point for further treatment.
2. In a method of treating paper pulp hereto.
RICHARD T. LANG.
