Description

[Detailed Description of the Invention] The present invention relates to an improvement of an electrostatic precipitator installed in a vehicle, for example.

FIG. 1 shows a resin electrode plate storage case of a conventionally used electrostatic precipitator, and this resin electrode plate storage case 20
A plurality of pairs of grooves 24 facing each other are formed on the inner surfaces of the top plate 22 and bottom plate 23, and a discharge electrode plate 25 and a dust collecting electrode plate are formed between the facing grooves 24. By inserting the ends of 26, both electrode plates 25.2
Six pieces are housed and held one by one.

However, in such a device, since the electrode plate housing case 20 is made of synthetic resin, the top plate 22 and the bottom plate 23 are distorted due to shrinkage after molding, as shown in the figure, and the space between the two plates is distorted. There was a drawback that the distance between the electrode plates 25 and 26 became narrow at the center of the top plate 22 or the bottom plate 23, making it difficult to insert the electrode plates 25 and 26 into the grooves 24.

This tendency is particularly noticeable in small-sized devices in which the width of the top plate 22 and bottom plate 23 is small.

This invention was made to eliminate such drawbacks,
It is an object of the present invention to provide an electrostatic precipitator that can easily accommodate electrode plates.

The present invention will be explained in detail below based on the embodiment shown in FIGS. 2 and 3.

In FIG. 2, reference numeral 2 indicates an electrode plate housing frame made of a synthetic resin material that houses the electrode plates of the electrostatic precipitator 1. One end edge of each plate 4 is connected in a U-shape, and one end edge of each of two inwardly facing plates 5 is connected inwardly to both end edges of this rain horizontal plate 4.

A plurality of grooves 7 are formed on the inner surface of the horizontal rain plate 4 at regular intervals along the longitudinal direction of the horizontal plate 4, and the grooves 7 correspond to each other between these inner surfaces and extend parallel to the vertical plate 3. There is.

Reference numeral 8 indicates a discharge electrode plate, and numeral 9 indicates a dust collection electrode plate, and the discharge electrode plate 8 and the dust collection electrode plate 9 are housed in the electrode plate housing frame 2 using the groove 7, respectively. It is meant to be retained.

Reference numeral 10 denotes a reinforcing plate which is screwed onto the inward facing plate 5 with screws 13, and 12 is a screw hole for the screw 13.

When using the above-mentioned device, since the tip of the horizontal plate 4 of the electrode plate housing frame 2, that is, the mounting end of the inward plate 5, is a free end, when attaching the electrode plates 8 and 9 to the electrode plate housing frame 2, Then, the rain horizontal plate 4 is slightly expanded in the direction of separating from each other, and the electrode plates 8 and 9 are inserted into the groove 7.

Further, after inserting all the electrode plates 8 and 9 in this way, a reinforcing plate 10 is attached to the outer surface of both inwardly facing plates 5 of the electrode plate housing frame 2.
Tighten with screws 13.

At that time, since the screw insertion hole provided in the reinforcing plate 10 is a long hole 11, the degree of tightening between the electrode plate housing frame 2 and the electrode plate 8°9 is adjusted, and the electrode plate housing frame 2 and the electrode plate 8, This absorbs the dimensional error of 9.

In the embodiment shown in FIG. 3, overlapping parts are formed at the tips of both inwardly facing plates 5', and one of the overlapping parts is formed with a long hole 11, and the other overlapping part is formed with a screw hole corresponding to the long hole 11. (not shown) and is configured so that both inwardly facing plates 5' can be integrally connected by screws 13.

According to this embodiment, the reinforcing plate 10 in the embodiment shown in the second figure
The electrode plates 8 and 9 can be mounted and fixed even if there is no.

As described above, the present invention is as described above, and a U-shaped frame 2 is formed by connecting one edge of each of two horizontal plates 4 to the upper and lower edges of a vertical plate 3, On the inside of the horizontal rain plate 4, a plurality of pairs of grooves 7 facing each other between the inner sides of the circle are formed substantially parallel to the vertical plate 3 and at predetermined intervals along the horizontal plate 4. The discharge electrode 8 and the dust collection electrode 9 were inserted into the groove 7, and the free end of the rain horizontal plate 4 was fixed by a fixing means. Even if the spacing between the horizontal plates becomes narrow and it becomes difficult to insert the electrode plates, the electrode plates can be inserted into the grooves very simply and easily by pushing the free ends of the horizontal plates apart in a direction. This has the effect of significantly improving the efficiency of mounting the electrode plate into the frame.

Furthermore, the two free ends of the rain horizontal plate are connected and fixed by means of fixing means such as screws, so that there is an excellent effect that the frame and the electrode plate are securely fixed.
