Specification of Letters Patent.
IatentedJune25,1912.
Application filed June 17, 1911. Serial No. 633,831.
To all whom it may concern:
Be it known that I, AUSTIN L. GRIFFIN, citizen of the United States, residing at Scranton, in the county of Laokawanna and State of Pennsylvania, have invented certain new and useful Improvements in Driers, of which the following is a specification.
This invention has relation to coal driers, and has for its object to provide pneumatic means for separating fine dusts and particles which are damp from larger particles and subjecting the said larger particles to a screening action, whereby they are rendered in condition proper to be used for fuel.
I/Vith this object in view the apparatus includes a shaker mounted for reciprocation and having a perforated corrugated bottom. A chute is arranged to deliver the mixed material at one end of the said bottom and the discharge end of a blast pipe is located under the delivery end of the said chute. A fan is mounted for rotation at the end of the blast pipe. A hood is mounted over the shaker and is provided with an outlet flue having suitable battle plates. A concaved screen is located in the side of the flue opposite the delivery end of the chute and blast pipe and against which the material is thrown by the blast. The larger particles roll down along the screen onto the bottom of the shaker while the finer particles are carried through the mesh of the screen and are expelled from the hood through the flue.
In the accompanying drawings: Figure 1 is a central vertical longitudinal section. Fig. 2 is a vertical transverse section on line 2 2 of Fig. 1, and looking in the direction of arrows. Fig. 3 is a horizontal section on-line 3-3 of Fig. 1.
Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.
As illustrated in the accompanying drawing the shaker 1 is provided with a perforated corrugated bottom 2 and is mounted upon wheels 3 which are adapted to travel upon tracks 4:. Any suitable means may be provided for reciprocating the shaker 1. The tracks A are provided at suitable intervals with knobs 5 over which the wheels 3 are adapted to pass as the shaker reciprocates and thus a vertical jarring movement is imparted to the shaker l and the material. passing over the bottom of the same.
A hood 6 is located over the shaker l and is provided at its top and at one side with a fine 7 and at its receiving side with an in wardly bent portion 6, which serves as a deflector. Baffle plates 8 are arranged in the said flue and in the upper portion of the said hood 6.
That side of the hood. 6 remote from the fine 7 is provided at its lower portion with an opening over which is located a concaved screen 9. The upper edge of the screen is in close proximity to the top of the hood and the lower edge of the said screen terminates at the lower edge of the hood. The hood and its contents are held in stationary position. A delivery chute 10 is located at the inlet opening of the hood 6 with its discharge end disposed downwardly toward the lower portion of the screen 9. An air blast pipe 11 has its discharge end located under the discharge end of the chute 10 and is directed toward the lower portion of the screen 9. A fan 12 is journaled at the discharge end of the pipe 11 and is fixed to a shaft 13 which in turn is provided with a wheel 14: whereby the said shaft and fan may be rotated to break the material as it comes from the chute 10.
In operation the mixed material is passed down through the chute 10 and out at the delivery end thereof onto the lower portion of the screen 9. At the same time a blast of air is passed through the pipe 11 and out at the discharge end thereof through the material which is coming from the chute 10. This blast of air will carry the material up along the concaved screen 9 and the wet dust and finer particles of material will pass through the mesh of the screen 9 and will be carried up by the blast through the fine 7 and out of the hood 6. The heavier particles of material will roll down along the lower portion of the screen 9 and fall upon the perforated bottom 2 of the shaker l. The reciprocatory action of the shaker 1 will Work this material toward the delivery end of the bottom 2 and in doing this the finer particles will be sifted from the coarser material and will fall through the openings in the bottom 2. At the same time the material passing over the bottom 2 will be subjected to the drying process of the blast of air passing through the hood 6 and the material delivered at the discharge end of the bottom 2 will be comparatively coarse grains of coal in proper condition to be used advantageously as fuel. During this process the coal Which is unfit for fuel is sifted from that which is fit to burn and at thesame time the wet dusts and other undesirable material will be separated from the coal by the action of the air blasts and blown from the hood through the said flue 7.
Having thus described the invention, what is claimed as new is:
A drier comprising a hood having at the lower portion of itsside an opening and provided in its top with a flue, aconeaved screen located in the 'hood over the said opening and having its intermediate portion spaced from the side of the hood having the opening, a chute arranged 'to deliver material through the'opening ofthehood against the screen, an air blast pipe arranged to deliver air against the screen and having its discharge end located under the delivery end of the chute, and a fan located at the delivery ends of the air blast pipe and the chute.
In testimony whereof Iaflix'my signature in presence of two wltnesses.
