INDUCTION EXHAUSTER.
Application filed March 31, 1927.
My invention relates to new and useful improvements in an induction exhauster, and has for one of its objects to provide a unique apparatus of the class mentioned which when used produces a new method of exhausting or drawing oft solids, vapors and gases from containers and conveying or projecting them to other receptacles or to a place of disposal.
The invention also contemplates an apparatus and method whereby the solids, vapors or gases will not come into actual contact with the mechanical actuating means.
Another object of the invention is the provision of an induction exhauster including a casing having a passageway therethrough tor a current of air set up by a suitable tan, blower or equivalent air circulating means, and further provided with a. secondary passageway communicating with the first memtioned one whereby an induced draft will be produced in said secondary passageway to draw contents from a. container, with which the secondary passageway also communicates, and into the first mentioned or main passageway so as to be conveyed to a receptacle or other place of disposal by the current of air.
For purposes of illustration and as an example of the working of the method the induction exhauster is shown as connected with a ball mill for exhausting the fine powdered material or dust resulting from comminution of the material by the hard balls in the mill, said material, for instance, being coal which is pulverized for combustion purposes.
\Vith these and other ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.
In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the acocmpanying drawings forming a part of this application, in which:
The figure is a side elevation of a ball mill with a portion broken away and shown in section to illustrate one method of connecting the induction exhauster which is shown in section with a container and conduits communicating with a fan and a re:
Serial No. 179,806.
ceptacle to receive the material drawn from the container.
In carrying out my invention as herein embodied, 2 represents a ball mill of usual or any desirable construction containing hard metal balls (not shown) for breaking up or reducing the material placed in the ball mill. The mill cylinder is shown as journalled in suitable bearings 3, surmounting pier supports 4. The end of the mill provided with a scoop 5 is the feed end, while at the other end is a discharge 6.
In the discharge is mounted a tube 7 suitably supported by apier 8, and the outer end of said tube is connected to the induction exhauster 9 through the secondary pas sageway 10 of said exhauster which, in turn, communicates with the main or primary air passageway 11. One end of the exhauster 18 connected with the outlet end of a fan, blower, or other suitable air circulating medium 12, while the opposite end of said exhauster is connected with a conduit 13 leading to a place of disposal, such as a receptacle 14;, although said point of disposal may be a dump or wast-e.
The exhauster includes a casing 15 in which the primary and secondary passageways are formed, and across said primary passageway is located a battle 16 having a hole 17 therethrough, preferably cent-rally of the passageway 11, and said baffle projects into the secondary passageway 10 so as to divide it into two sub-passageways 18 and 19.
From the foregoing description, it will be obvious that part of the air circulated by the fan 12 will pass through the hole 17 in the baflie 16, while another portion will be deflected through the sub-passageway 18 into the tube 7, and under some conditions into the ball mill cylinder. The portion of the air current passing through the hole 17 will induce a draft through the sub-passageway 19, and cause the air in the ball mill cylinder to be exhausted with suificient velocity to carry the finer material with it from the ball mill back through the tube 7, and through the sub-passageway 19 into the primary passageway 11, thence through the conduit 13 to the point of disposal. In the case of coal, the fine particles reduced from the main bodieswithin the ball mill will be finally deposited in a receptacle 14,
and the contents of said receptacle may then be removed as desired, and utilized.
As before stated, the showing is only illustrative of the use of my invention, and
shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.
Having thus fully described my invention, what I claim as new and useful is:
1. The herein described combination of a container, a passageway leading from said container, another passageway with which the, first mentioned passageway communicates, an air circulating medium connected with one end of the second named passageway, and a battle provided with a hole lo cated across said second mentioned passageway at the point of communication with the first mentioned passageway and dividing said first. mentioned passageway into subpassageways. j
2. In a device for conveying solids, vapors or gases from a container to a receptacle at a pointdistant from the container including a fan, an exhauster casing provided with a primary passageway connected with the fan so that its exhaust communicates with one end of the primary passageway, a conduit also connected with the exhauster casing so as to communicate with the other end of the primary passageway and leading to a point of disposal, a secondary passageway communicating with the primary passageway so that any of the solids, vapors or gases passing through the exhauster will not come in contact with the fan, a bafiie within the exhauster casing and disposed across the primary passageway and projecting into the secondary passageway to divide the latter into sub-passageways, said baflle having an opening therethrough centrally ot' the primary passageway to perinit a portion of the air current from the fan to pass therethrough and induce a draft through one of the sub-passageways, said draft being supplied with air through the other subpassageway, which air has been deflected by the baflle, a container, and means to form a communication between the interior of the container and secondary passageway of tie exhauster casin in testimony whereof, I have hereunto ailixed my signature.
