    An electrode cleaning mechanism for electrostatic dust precipitators is disclosed which has at least one eccentrically mounted electrode vibrated by a rapping mechanism which includes a tumbling hammer that is rotated about a horizontal shaft so that it continually swings down in a pivotal pendular movement until the impact surface of the hammer strikes against the end of a rapping bar which is thus sharply moved axially out of a rest position to jar the electrode. The rapping bar is urged back to its rest position after jarring the electrode by the weight of the eccentrically mounted electrode which is connected to the rapping bar during this return movement.

    专利说明:

    The invention relates to the regeneration of electrostatic plants, and can be used in the industry for the dedusting of flue gases, for example, in the production of cement. A shaking hammer mechanism is known for shaking the collecting electrodes of the electrostatic precipitator, which contains a horizontal rotating shaft on which the hammers with a rounded impact surface are hinged, and the anvil fixed on the collecting electrode has a hollow surface 1. A disadvantage of the known shaking hammer mechanism is the fact that during the operation of the electrostatic precipitator at high temperatures individual parts are subjected to significant deformations and, as a result, there is no constant central rounded hammer blow on a flat anvil. The aim of the invention is to increase the degree of cleaning of the electrodes. This goal is achieved by the fact that the rod has a convex end surface and is provided with a rounded shock element facing the electrodes, and its axis of symmetry co ff coincides with the axis of the rod, while the axis of the shaking rod and the direction of dynamic action coincide even in that case slight displacements of the relative positions of the rotating hammer and the shaking rod occur, such displacements occur, for example, due to deformations of the filter housing of the dust separator or due to the difference of those Pilov filter housing extensions and collecting electrodes. Fig. 1 shows a first embodiment of a device for cleaning electrodes; figure 2 - the second variant of the device; on fig.Z- general view of the electrostatic precipitator. The collecting electrodes 1 are made in the form of plates, the shaking rods 2 are freely connected to each other. The collecting electrodes are suspended freely by connecting parts 3 (Fig. 2) to the fixed supports 4, and at their lower ends they have ridges 5 connecting them to the shaking rods 2, so that one shaking rod is common to a number of collective electrodes.
    In the first embodiment, the shaking rods 2 are suspended from collecting electrodes, while the ridges 5 pass through slots made in tubular shaking rods, so that the rods are suspended on bolts b passing through the ridges 5. Rounded are attached to the tubular shaking rods. percussion elements 7, which transmit dynamic effects from the rod to the plates 1 through the ridges 5. At the ends of the shaking stem, round pins 8 are installed, interacting with the rotating hammers 9. The rotating hammers 9 have The possibility of turning on the levers 10, which are fixed on the shaft 11 by means of clamping clips 12 with two nuts. The shaft 11 is mounted in fixed supports 13. The shaft is driven by a gear and a motor.
    In the second variant, the shaking bars 2 are not suspended on the collecting electrodes, but are supported on the holders 14 and 15. The holder 14 is provided with a clip 16, and the shaking rod interacts with the brake shoe 17 to ensure the correct position of the shaking rod in the longitudinal direction. The holder 15 is attached to the support 18, which simultaneously serves to support the fixed supports of the shaft 11.
    The collecting electrodes are eccentrically suspended, and since the tubular shaking rod 2 has the ability to slide on sliding surfaces made on the holders 14 and 15, the collecting electrodes cause the shaking rod 2 to move to the left until the clip 16 is turned off brake flask .17. Therefore, in its fixed position, the shaking rod will occupy the same position, which relative to the position of the corresponding shaking hammer is determined so that the impact surface of the rotating hammer is perpendicular to the axis of the shaking rod at the moment of impact.
    During operation, the shaft 11 rotates counterclockwise and for each revolution the rotating hammer hits the shaking rod. After impact, the rotating hammer under. lever, 10, during the subsequent movement of the indicated lever 1 down. The rotating hammer is stationary on the lever until it goes out of balance, pad in the free swing movement down onto the shaking bar anvil.
    Since the distance between the point of impact and the axis of rotation is equal to the radius of circular motion, it is practical;
    Combing it, there is no effect from hitting the rotary hammer.
    The rotating mylot knocks on the center of the bucket, i.e. to a point located along the center line of the shaking boom shank, and the dynamic impact of the shaking boom is transmitted through the rounded percussion elements 7 to the ridges 5 and, therefore, to the collecting electrodes.
    Q Since the rotating hammer strikes the center and the energy of the dynamic effect is transmitted through the rounded percussion elements in the center, the maximum power will be used to vibrate the collecting electrodes.
    The built-in mechanism will have a long service life, due to the absence of uneven impacts.
    In the shaking mechanism shown in Fig. 1, it is only necessary to fasten the shaking rods. The rods are in their fixed position, while the longitudinal movement of the shaking rods from the impact point is limited by the inertia force on the system.
    To further guarantee that; the supporting collecting electrodes in their stationary position in contact with the striking elements 7, in the shaking rod for the first and last collecting electrodes of the row, plate-shaped wedge-shaped parts 19 can be fixed. Due to the fact that the levers 10,
    The g to which the rotating hammers 9 are attached are mounted on the shaft 11 by means of clamping clips 12, the position of the rotating hammers relative to the anvils 8 can be adjusted quite easily so that
    0 the ability to properly adjust the shaking mechanism. In addition, it is possible to make any necessary adjustment of the sequence of impacts of a number of rotating
    5 hammers.
    As shown in FIG. 3, the electrodes can be mounted in a filter case 20 supported on structure 21. The case has one or more bottom hoppers 22 for collecting dust falling from the electrodes. The hammers 9 are mounted outside the casing 20, and the shaking rods 8 extend inside the casing through the holes in the casing, which are sealed with elastic membranes 23.
    The revolving hammers of the illustrated switchboard can certainly be used to shake the support for the discharge electrodes or other mechanical devices connected to the discharge electrodes.
