Description

[Detailed Description of the Invention] This invention relates to an electrode plate transfer device for a rotating electrode type electrostatic precipitator in which the upper end of the electrode plate is suspended and rotated.

The first electrode plate transfer device for a conventional rotating electrode type electric concentrator
As shown in the figure.

In the figure, an electrode plate 1 is always vertically suspended by its own weight at both upper ends of a link chain 3 which is suspended from a sprocket 2 which is rotated by a drive device.

The gap g between each electrode plate 1 is maintained to such an extent that the electrode plates do not come into contact with each other.

The electrode plate 1 lifted vertically by the link chain 3 moves on the circumference of the sprocket portion and continues to descend.

In this case, the pair of left and right sprockets 2 are rotated synchronously by the drive shaft 4.

In the device having the above structure, when the electrode plate 1 approaches the circumference of the sprocket, as shown in FIG. The gap between the bottom edge of the plate and the top edge of the succeeding electrode plate will shrink, but at this time, the link chain and electrode plate that have reached point a may not be completely vertical due to their own weight, as shown by the two-dot chain line. may be overtaken by subsequent electrode plates, making normal transition impossible.

The purpose of this invention is to eliminate the drawbacks of the prior art described above and to provide an electrode plate transfer device that can reliably transfer each electrode plate around the circumference of a sprocket.

In order to achieve the above object, this invention is an electrode plate transfer device for an electric concentrator in which electrode plates are suspended at predetermined intervals on a link chain suspended from a drive sprocket and rotated. The present invention is characterized in that a link mechanism is provided which has a fulcrum and holds the electrode plate vertically from both sides of the fulcrum when the electrode plate moves along the circumferential portion.

This invention will be explained in more detail below with reference to the drawings.

FIG. 3 is an explanatory view showing the transition state of the electrode plate when the link mechanism according to this invention is provided.

The link mechanism swings a substantially inverted dogleg-shaped link member 13 to a fulcrum P on the outside of the point where the link chain 3 bends along the circumference of the sprocket 2 so that the center of gravity is at a position below the fulcrum P. It is attached so that it can move freely.

In the unloaded state, the link member 13 is in a state where the upper circumference of the sprocket 2 and the link member 13 overlap as shown in FIG. At the point in time when the link member 13 rises along the fulcrum, the head part H and the tail part T come into sliding contact with the electrode plate on both sides (upper and lower) of the fulcrum of the link member 13, and are arranged so as to vertically support the electrode plate 11.

That is, in Fig. 3A, if the gap between the leading electrode plate 11 and the succeeding electrode plate 12 is gl, the gap g1 becomes smaller as the electrode plate moves from the mouth to the 8th position, and at 8th position g = 0. .

On the other hand, the link 13 rotates around point P, but as the tip of the leading electrode plate 11 hits the link 13 as shown in the figure, the tail part T presses the lower part of the electrode plate 11, and the electrode plate becomes vertical. is maintained.

Further, in C, at the time when the succeeding electrode plate 12 overtakes the preceding electrode plate 11, a gap X through which the succeeding electrode plate 12 can pass is secured.

Then, in step 2, when the succeeding electrode plate 12 passes outside the leading electrode plate 11, the point a at the tip of the leading electrode plate 11 separates from the head portion H.

At this point, the tail portion T of the leading electrode plate 11 is far away from the trailing electrode plate 12, and they no longer come into contact.

As described above, according to this invention, in a rotating electrode type electrostatic precipitator, when the electrode plates move along the bent part of the link chain of the sprocket, contact between the electrode plates is prevented, and the electrode plates are smoothly transferred one after another. can be done.
