FLUID 0R AIR DIRECT PRESSURE LIFTING'AND FORCING APPARATUS FOR SOLIDS AND SEMISOLIDS APPLICATION FILED FEB. 28. 1919.

FLUID 03 AIR DIRECT-PRESSURE LIFTING AND Foncme ArPAm'rUs FOR SOLIDS AND SEMISOLIDS. 1

To all whom it may concern:

Be it known that we, SAMUEL HENRY ADAMS and COLIN HENRY ADAMS, both subjects of the King of Great Britain, and residents of Fulford, York, England, have invented' new and useful Improvements in Fluid or Air Direct-Pressure Lifting and -Forcing Apparatus for Solids and Semisolids, of which the following is a specificatic n. 4

Our invention relates to apparatus for the raising and discharge of solids and semisolids such as coke breeze, coal clinker, sand,

heavy oils and pulp and other 'such material which would owing to their nature'of necessity am and block up'a'n ordinary ejector of the direct air pressure displacement type. j

According to our invention, in order to prevent such 'amming and blocking of the ejector we ma 'e the receptacle with a closed rounded bottom and we perforate the mass of material with pipes or tubes or other fittings which are suitably held within the receptacle and through these a given proportion of the pressure-fluid, e. g. compressed air or pressure water or steam, or of a mixture of such fluids, will pass, exerting its pressure either for lifting or forcing the material from beneath as well as, fromabove and in this way loosening and breaking up the mass to such an extent that'itwill enter-into the lower open end of a discharge-pipe extending downwardly into'the receptacle and be driven up to'the height required. We use suitable connections through which the pressure fluid is discharged in jets or in a stream into any desired part of our ejector or its fittings, as for instance into the body of the mass of material, and into the intake mouth of the discharge pipe andinto the inlet and outlet valves and other fittings, provided always that these jets are so placed that they expedite the entry'of the "material into the ejector body and the discharge of the material from it, and in this way we make it possible to handlesolid and semisolid material, whether in a dry or wet state,

. by,means of a fluid o'rf air or steam-pressure forcing and dispgi'arging apparatus. Whether these jets are. erivedfrom the "ap paratus itselforfroma separate source of supply, and whether they are automatic in their operation or depend upon the opening and closing of suitable valves by hand, is

Specification of Letters Patent.

immaterial, provided the aid in-the discharge of ,the material. hile we prefer the automatic valve shown, it is evident that we may use any other suitably constructed valve, provided that it is capable of the necessary adjustment and determination both as to the duration of time necessary for supplying the pressure fluid to the ejector and as to the duration of time required for the exhaust air to escape therefrom. It

will be apparent that the time required for both operations will vary and will depend upon the'nature of the material to be ejected. Figure 1 shows in section our displacement apparatus specially fitted for the discharge I Patented July 20, 1920. Application filed February 28, 1919 Serial No. 279,830.

instance,'the mass of sand within the receptacle is pierced by the pendant air pipes f, f, 7, which are connected to the main supply pipe e, suitable control valves being fitted at 9. At It is a branch pipe leading from a separate supply to the upper extremity of the receptacle at j. This pipe is fitted with.

a valve is; At Z is an extension of the air pipe 6 through which air is brought to the receptacle at its lower extreinity and discharged into the mouth of the delivery pipe l through the nozzle m. At 12 is a valve by means of which the volume of air passed to m may be controlled. At ;'0 is an orifice which we mayuse :We wish on the de livery pipe in order "to aidthe up current which carries the sand and also to serve if we wish as a means of exhaust forthe air which is driven out of the closed receptacle by the sand or other material "which fills it. When we use this orifice it is evident that as it serves as an exhaust outlet, the air main will be used only to bring com ressed air to the ejector in order to -disp ace its co tents and never to take the exhaust, from it, so that theair valve would never beafi'ec t- .ed by anything contained in theexhaust air.

The air valve 1* having the usual inlet and exhaust connections is opened 'and closed at open and exhaust the vent aperture and .allow air to escape from it as the ejector fills and shuts off the exhaust and admits compressed 'air to the ejector when the latter is filled in order to drive out the contents.

thereof. This valve is placed at such a distance'from the ejector (and operated apart from it) that it shall not be affected or damaged by the material handled by the:

ejector. It may be operated through a belt from an electric motor .(not shown). The valve shown is of the construction described in the specification of British Patent No. 117,643. Other equivalent forms of valves may be employed for this purpose.

In operation, assumingthat the recep-.

tacle is full of dry sand, ash, breeze or similar material and that the compressed air is admitted to 'the receptacle and that the valve a is open sufliciently and that the valve 9 is sufficiently open then the compressed air disehargedfrom the pendant I pipes f, f, f, will agitate the whole mass of of the rece tacle, and at the same time the jet of air" rom the nozzle m which is d1S- sand which. will be downwardly displaced by the pressure of air in the upper extremity charging into the mouth of the delivery pipe at will drive the sand up into this pipe 71. e. the result of the combination of these two air forces from above downward and from below upward, will drive the sand,

coke breeze or other material upthe discharge pipe until the receptacle is entirely emptied. The compressed air then being shut off will allow the receptacle to fill, the

exhaust taking place either through an exhaust valve or through the orifice 12 (as in this instance) and the o eration will be repeated indefinitely. e may bring in a supply of water or air under pressure either separately or together in suitable proportions to further the object we have in view, as, for instance, at v where a jet is used to drive the material from the hopper into the body of the ejector below the non-re'turn valve 6 which this jet of water will keep clean At w is a connection which we may use-if it is wished to bring in another current, of compressed air into the discharge pipe. It is evident also that we may bring in pressure water or other fluid into such a receptacle through such pipes, f, f with a water or air jet at when we are dealin with dry or Wet sand in combination wit an air pressure pipe for displacing the contents of the ejector by the desired pressure of air.

What we ,claim is 1. A displacement ejector consisting of ing said va ve.

closed receiver with an inlet for the material pipes are alternately connected to the sourceof compressed air and are disconnected therefrom.

2. A. displacement ejector consisting of a closed receiver having a rounded bottom and an inlet at its upper part for the material to be ejected, air-pipeeconnections to the upper part of the receiver, a concentric series of air pipesopening in a downward direction into, the receiver around the lower part thereof, a discharge pipe extending into said receiver and opening 1n a downward direction in the vertical axis of the receiver near the .bottom thereof, an air-pipe extending into the bottom of the receiver and opening upward in the direction of the inlet of the dlscharge pipe, a source of compressed air,

an air outlet and a valve whereby said airpipes are alternately connected to the source of compressed air and are disconnected therefrom.

3. A displacement ejector-consisting of a closed receiver having a rounded bottom and an inlet at its upper part for the material to be ejected, a valve controlling said inlet, air-' pipe connections to the upper part ofthe receiver, a concentric'series of air pipes opening in a downward direction into the receiver around the lower part thereof, a discharge pipe extending downward into said rece ver and .openmg in a downward direc tion in the vertical axis of the receiver near the bottom thereof, an air-pipe extending into the bottom of the receiver and opening upward in the direction of theinlet of the discharge pipe, a source of compressed air, an air-outlet, a valve whereby such air-pipes are alternately connected to the source of compressed'air and disconnected therefrom,

and gearin driven continuously for operat- A A SAMUEL-'HENRY-ADAMS. I,

COLIN HENRY ADAMS.
