process and forming a part of theinvention.
In this showing,
Figure 1 is a side elevation, parts being shown in section, Figure 2 is a horizontal sectional .viewof the drying apparatus substantially on line 2-2 of Figure l, v
Figure 3 is a vertical transverse sectional View on line '33 of Figure 1, and Fig. 41 1s aside view of the agitator. 1
Referring to the drawings the reference numeral 1 designates generally the casmg of the drier or kiln. casing I provide a shaft 2 disposed hor zontally and at the outlet end the shaft is connected to a motor 3 or other source of power bya belt 1 or other suitableconnecting means. Anendless belt or apron 5 is adapted to pass over-rollers 6 mounted on the shafts 2. At the inlet end of the easing I provide a shaft 7 arranged above the apron and provided with knives orshredders 8. At spaced points within the casing I further provide transverse shaft-s 9 havlng sultable agitating blades 10 arranged thereon. At the inlet end of the machine there is provided a chute 11 adapted to deliver material to the belt from a standard Wet machine mounted at a suitable elevation on a platform 13. At one side of the casing I provide an auxiliary compartment 14 extending substantially throughout the length of the casing and provided with heating coils 15. A partition 16 separates the auxiliary compartment from the main compartment and this partition is provided with a plurality of openings 17 adapted to receive fans 18. As shown, a stack 19 is connected to the casing adjacent its inlet end.
At the outlet end of the machine I pro- At each end of the vide a transverse conveyor 20 adapted to delend strength to the finished paper stock.
When the pulp is in a Wet condition, however, the fibers readily absorb moisturethus almost wholly losing their tensile strength, and it is difficult to effect the shredding of the pulp withoutinjuring the fibres thereof. It has been found that any rapidly rotatingshredder of the beater type is wholly impracticable for use in shredding Wood pulp, and accordingly I employ a knife shredder of the character referred to. The shredding knives are rotated-at a relatively low speed. the knives gently pulling small pieces of pulp from the body of the sheet and thereby substantially finely dividing it. The pulp is not finely shredded, but is divided into relatively small pieces which range up to. approximately one inch in diameter. The pieces of pulp thus shredded pass to the belt 5 in asubstantially loose divided form and pass through the kiln to be dried. The hot air generated in the compartment 14 by the steam eoils'is fed into the main section of the drier. casing by the high speed fans 18 and exhausted through the stack 19. A temperature of substantially 120 F., is maintained in the drier and the speed of the conveyor regulated to a speedof substantially 7 feet per minute; The pulp is turned during its travel by the agitator blades 10 to present opposite sides of the pieces of pulp to the action of the hot air size, shape and arrangement of parts may be made Withoutdeparting from the spirit of the invention or the scope of the subjoined claims.
I claim:
1. The method of treating wood pulp which comprises delivering Wet pulp tov a knife shredder in a relatively thin layer to substantially finely divide the pulp Without injury to the fibres thereof, and then passing the shredded pulp through a drier.
2. Themethod of treating Wood pulp which comprises delivering Wet pulp to a knife shredder in a relatively thin layer to substantially finely divide the pulp Without injury to the fibres thereof, and then passing the shredded pulp through a drier at a temperature of substantially 120 F.
The method of treating WOOLl pulp which comprises delivering Wet pulp to a knife shredder in a relatively thin layer to substantially finely divide the pulp without injury to the fibres thereof, passing the pulp through a drier, and turning the pulp at intervals Within said drier.
4. The method of treating Wood pulp a substantiallyloose divided condition by pulling relatively small pieces from the body of the pulp Without injuring the fibres thereof, and dryingthe pulp While in such condition.
5. The method of treating wood pulp which comprises shredding Wet pulp in a substantially loose divided condition by pulling relatively sinall'pieces from the body of the pulp without injuring the fibres thereof, and subjecting the pulp to the action of heatedair to dry it. 7
In testimony whereof I affix my signature.
