ROTARY MEANS FOR CLEANING ELECTRODES.
Application flied April 29, 1921. SerialNo. 465,521.
To all whom it may concern:
Be it known that I, HARRY A. ,WINTER- MUTE, a citizen of the United States, residing at Branchville, in the county of Sussex and State of New Jersey, have invented certain new and-useful Improvements in R0 tary Means for Cleaning Electrodes, of which the following is a specification.
The present inventlon relates to electric 1o recipitators such as are commonly used or separating from gas particles suspended therein.
' To insure proper operation of a precipitator, the dust deposited on the electrodes must be removed from time to time and for I this purpose rapping or jarring devices are usually applied. Y
While rapping devices such as are commonly resorted to are effective, they'take up valuable space between the treater tubes and thereby lead to a reduction of the treater capacity per unit area of floor space or to a relatively large cross-section per unit .ca-
pacity.
In practice the discharge electrodes must also be cleaned from time to time. It is therefore necessary as a rule, to install a separate device for cleaning the discharge electrodes in addition to mechanism for cleaning the collecting electrodes.
It is an object of this invention to provide an arrangement for cleaning electrodes which permits a close nestling of the treater tubes and thereby affords economy of flow space. 1
Another object is to provide a single mechanism for simultaneously cleaning both, the
collecting electrodes and the discharge electrodes of the treater. Another general object is an arrangement for the purpose indicated which is simple in construction and operation.
In its simplest aspect the invention comprises chain discharge electrodes or electrodes having the characteristics of chain electrodes and means for swinging them so that they sweep along the surface of the collecting electrodes. 1
To illustrate the invention reference is had to the accompanying drawings which show what I consider at present a preferred embodiment thereof.
- In the drawings Fig. 1 is an elevation; and
'55 Fig. 2 is a plan view of an arrangement the discharge electrode system.
for carrying out the objects of the invention.
The treater shown comprises four treater units, each having 16 individual tubes 10 and as many discharge electrodes 11. The electrodes which are chains are suspended from L-beams 12 resting on beams 13 of suitable construction. The treater arrangement is or may be of the usual type and need not bedescribed in detail.
In the particular construction shown, the discharge electrodes 11 carry rapping guide frames 14, intermediate the top of the collecting electrodes and the point of suspension. These frames may be of any suitable construction. Their purpose is merely to rigidly interconnect the electrodes so as to cause them to be swung in unison when the frames are swung.
While there is considerable latitude in the selection of means for swinging the guide frames 14, I have found the arrangement shown as particularly advantageous. To the frames are connected, preferably near the center thereof, plates 15 provided" with a round aperture having downwardly tapering walls.
Above the supporting frame comprisin the beams 12 and 13 are mounted frames 1 and 18 for supporting shafts 19 and mechanism for. raising and lowering them and for revolving them.
The'shafts 19 carry at their lower ends eccentric pivots 20 fitting the apertures. When the shafts are revolved, the ivots 20 cause the frames 14 to rotate an impart a circular swinging movement to the electrodes 11.
The shafts 19 are normally, i. e., during the operation of the treater, in raised position and therefore entirely removed from For raising and lowering the shafts 19 any suitable mechanism may be provided. In the particular construction shown I use bell crank levers 21 slidably engaging couplings 22 100 having the usual slide wayv 23 for receiving pins or journals on one arm of the lovers. The levers are .pivotally mounted on brackets 24. The second arm of the lever may be engaged by a rod 25, provisions being made 105 for relative slidin movement between the arm and the rod uring angular movement of the lever 21. The shafts 19 may be driven by an electric motor 26 and bevel gears 27 and28, the 1 0 shafts being connected to one of the gears by a sliding spline connection.
Provisions, are, of course, made for guiding the shafts in up and down direction. The frames 17 and 18 may carry bearings 29.and 30 respectively in which the shafts are revolved and moved lengthwise of their axes.
The "inoperative position of the shafts 19 is indicated .in full lines in Fig. 1. When it is intended to rap the electrodes, the rods are pulled outwardly, causing the bell crank levers 21 to turn to lower the shafts 19. The motor is then started to rotate the frames 14:.
In practice the eccentricity of the pivots 20 may be relatively small, i. e., about a" in the usual treater construction. The rotation of the frames 14 will set the electrodes 11 in swinging condition. The centrifugal force will in practice be sufficient to carry the chains outwardly in contact with the surface of the collecting electrodes, thereby removing the deposit from them and simultaneously undergoing themselves a thorough cleaning action. If the electrodes are too light to be thrown outwardly sufliciently far to carry out the cleaning function, weights may be attached thereto between of the collecting electrodes and the guide grame it as indicated by the numeral 16 in t is understood that below the collecting electrodes the discharge electrodes are held in centered osition by the usual spacing frame (not s and are normally held obviously available.
