To allwlwm it may concern:

Be it known that we, FRED E. Knnre and LUTHER B. WEIDLEIN, citizens of the United States, and residents of Youngstown, in the county of Mahoning and State of Ohio, and Cleve and, in the county of Cuyahoga and State of Ohio, respectiveliv, have invented certain new and useful In vements in Dry Gas Cleaners, of which following is a specification.

This invention relates to gas cleaners, and more particularly to dry gas cleaners for use in removing particles of coke, o and lime dust, etc., from the gas coming om blast furnaces, and has for one of its objects the provision of such a device that will have a higher efiiciency than the cleaners heretofore constructed.

Another object is to provide a cleaner that will not lower the temperaturfi of the gases any appreciable amount.

Another object is the provision of a cleaner that will have less resistance than those known in the art, and one thst will re uire very little power to operate 1 further and important, object is the provision of a cleaner having an entirely automatic operation, thereby reducing the cost of operation to a minimum.

Other objects and advantages of the invention will be readily apparent to those skilled in the art, and will be disclosed in the following specification and claims. a

F cleaner shown in Figures 1 to 7 of a series or battery of units Y, all of like construction and operation, so !it will suflice to describe one unit in detai The numeral 2 designateii the side walls of each of the units which have a flat top wall 3, and convergin bottom walls 4 and 5 which sustain closing bells 6, 7, and 8, thereby forming a closed main chamber A.

The main hamber or interior of each unit is divided into two sections B and O by

transverse walls

9, 9, 10 and 10. The

walls

9 and 10 terminate an a preciable wall 3 an converge toward the top, and

t e walls

9 and 10 converge toward the bottom, forming a sub stantially diamond-shaped sub-chamber 11. Thechamber 11' has an opening in its bottom closed by bell 7 for the discharge of forei meitter which is collected in the chem r,

nd gas'exit openings

24 and 25 in its side we ls.

A filter that member 12 is arranged within the chamber 11 and supported on a flange 15 below the

openings

24 and 25. A shaft or rod 13 passes through cross supports 01' girders 14, and has its u r end mounted in or connected with she. mg or vibrating mechanism D, and its-lower end mounted for movement through an aperture in shock receiving member 13' on the mzi't l2, and thereon. The rod 13 is adapted to move freely down through the shock receiving member 13 and its head 13" is adapted to deliver an upward vibrating stroke or shock to said member on the upward stroke or movement of the rod.

Other filter mat members 16 and 17 are supported on flanges 18 and 19 secured on the side walls 2, and on the top of the

Walls

9 and 10, thereby closing the to of the sections B and C of the main cham r A.

The filter mats 16 and 17 have operatin shafts or

rods

20 and 21, respectively, whic have their u per ends mounted in or connected with sliaking or vibrating mechanism Dd, and their lower ends mounted for movement through apertures in shock receiving members 16 and 17 on the respective mats. lhe rods 20 and 21 have

heads

20 and 21 respectively on their lower ends to deliver an upward vibrating stroke or shock to members 16 and 17 on the upward stroke or movement of the rod.

The filter mat members may be of any desired construction, but are preferably formed of metal w0ol held between two sheets of wire mesh or fabric with suitable support ing or stiffening members.

An inlet main 22 extends along the bat tery of units and has a branch pipe 23 extending into the sub-chamber 11 of each unit below the filter mat 12, through the pipe 23 passes through the filter mat 12 and out through the outlet openings or

exits

24 and 25, respectively, into sections B and C of the main chamber, then through the mats 16 and 17 arranged above the

outlets

24 and 25, and into the upper portion of the main chamber A.

The main chamber A has an outlet pipe 26 extending from its upper portion abovethe mats 16 and 17. Pipe 26 has a valve casing 28 mounted intermediate its ends, and a gate or butterfly valve 28 is operatively mounted within the casing so as to be nor- .mally closed by a counterweighted lever 28". The pipe 26 enters or communicates with a gas main 27 which carries the clean gas to suitable points of distribution.

The vibrators and Dd may be of any preferred construction, and are adapted to e automatically set in motion by, and to receive their power through clutches 35 on the power driven shaft 36 which extends longitudinally above the battery of units and receives its power from either the direct current motor X and its connecting aring 36", or the alternating current motor sll, and its connecting gearing 36".

Clutches 35 are automatically thrown into and withdrawn from operative engagement at predetermined intervals by'clutch levers 39 which are actuated by c'am melnbers 37 on a shaft 38 which extends parallel to shaft 36, and is constantly driven through gear 38 which is in mesh with gear 38 on the drive shaft 36.

The valve 28 is adapted to-be operated synchronously with the shaking mechanisms D and Dd by means of lever mechanism 29 which is operated by a cam 30 on the shaft 38, which is so positioned and shaped that it holds the lever mechanism and valve in open position for the major portion of each revolution. but will release the lever mechanism and valve to the action of the counterweighted lever 28 to close or seat the valve for a minor portion of each revolution. The

and gas entering' 'or vibrated by means of the

rods

13, 21, and vibrating action of the cam 30 is so timed that the valve 28 will be released to the action of the counterweighted lever 28' and consequently seated at and durin the time the shaking mechanisms D and motion by the engagement of clutches 35, so as to prevent gas passing out of the units while the mats are being cleaned.

The shaking or vibrating mechanisms D and Dd are the same for each of the several units.

The 0 aeration of the device as described is as follows- Gas enters the inlet or main 22 from a blast furnace or other source and flows through the branch 23 into the sub-chamber 11 and passes upward through the filter mat 12, thence through the opening or

exit

24 and 25 into the chambers B and C, respectively, and thenupward through the filter mat members 16 and 17 into the upper portion of the main chamber 'A, then exits through the clean gas or outlet pipe 26, then into the main 27 for use.

At predetermined intervals the filter mats 12, 16 and 17 will be automaticallysgaken and mechanism D and Dd to remove the trapped dust and particles of to ,eign matter.

As has been stated, the entire operation of the device is automatic. nism 29 is operated by a cam 30 and butterfly valve 28 closed, and simultaneously with the closing of the valve 28" the shaking or vibrating mechanism D is automatically set in motionand the dust and other foreign particles are released from the filter mats and falls to the bottom of the chambers. The dust is removed from the chambers B, C, and 11 by removing the bells or traps 6, 7 and 8, while the gate valve 28 is closed.

In Figures 8 and 9 I have shown a modia tied construction of gas cleaner embod ing the general features of my invention. cleaner consists of a plurality of units Yy, 6f, duplicate construction, each of which consists of side walls 50, curved top wall 51, and a tapering bottom portion divided by a sharp downwardly sloping wall 52 to form

hoppers

53 and 54, closed by bells or traps 53 and 54. y

The units are supported in superstructure, composed of suitable upright supports 55 set on bases 55 and having a suitable housing 56 arranged over the tops of the units to house theo ating mechanism.

A single lter mat 57 composed of a plu rality of layers, and consequently ofiering substantially as much cleaning surface to the gases as the plurality of mats in the ferred form, 18 mounted within the units d are set in his The lever mecha- 3/ and normally rests between the flanges 58 (it a suitable channel mounted around the in terior of the units. The mat is connected to a shaker or vibrating mechanism D by means of a rod 59 which has its lower end mounted for movement through apertures in shock receiving member 6%) on the mat, and is provided wlth a head 61, to deliver an upward vibrating stroke or shock to members 60 on the upward stroke or movement of the'rod.

The vibrators or shakers D are adapted to be operated at predetermined intervals by suitable mechanism (not shown) to reclprocatethe rods 59 and thereby shake or vibrate the mats to clean them.

A. feed or supply main 62 extends along the battery on one side of the units, and has a branch 63 entering each unit below the mat 57, and an outlet main 64 extends along the other side of the battery and is con nected to each unit by a branch 65 which enters or. communicates with the unit above the mat 57.

A gate or butterfly valve 66 is mounted within each branch 65, and is provided with lever operating mechanism 67 and a counterweighted lever 68. The lever 68 is adapted to normally hold the valve 66 closed while the lever mechanism 67 is adapted to be operated by a cam 69 on drive shaft of the vibrating mechanism D to open the valve against the action of the counter- Weighted lever 68 for a predetermined time, and to release the valve to the action of the counterweighted lever 68 simultaneously with the starting of the vibrating mechanism, thereby stopping the flow of gas through the unit while the mats are being cleaned.

The operation of this modified battery of units is automatic, and in general the same as that of the preferred form, with the exception that gas will only pass through the one filter mat, while in the preferred form it passes through several.
