考案の好ましい実施態様
この考案に用いる集塵プレートにおいて、上記
永久磁石の使用量を最小限にし、小型化及び磁気
吸着集塵効率の向上を計るには、下記する条件が
有効であることを知見した。In the dust collection plate used in this invention, it has been found that the following conditions are effective in minimizing the amount of permanent magnets used and in achieving miniaturization and improved magnetic attraction dust collection efficiency.
角柱状永久磁石が２個の場合；
角柱状永久磁石の幅Ｗと高さLmとの比は、隣
接磁石との相乗効果が得られるため、2.5〜4.0の
範囲外では、永久磁石を大きくするのみで、磁気
吸着力の大幅な向上が望めない。すなわち、Ｗ／
Lm＝2.5〜4.0が望ましい。 When there are two prismatic permanent magnets; The ratio of the width W to the height Lm of the prismatic permanent magnets provides a synergistic effect with adjacent magnets, so if it is outside the range of 2.5 to 4.0, the permanent magnets should be made larger. Therefore, it is not possible to expect a significant improvement in the magnetic adsorption force. That is, W/
Lm=2.5-4.0 is desirable.
磁石間に介在させる非磁性体の厚みｔと角柱状
永久磁石の高さLmとの比は、非磁性体が永久磁
石磁極表面から発生する磁束を遠くへ飛す効果が
あるが、必要以上に間隔を広げると隣接磁石の相
互効果が弱まるので好ましくない。よつて、
ｔ／Ｗ＝0.04〜0.06が望ましい。 The ratio between the thickness t of the non-magnetic material interposed between the magnets and the height Lm of the prismatic permanent magnet is such that the non-magnetic material has the effect of dispersing the magnetic flux generated from the permanent magnet magnetic pole surface far away, but Increasing the spacing is not preferable because it weakens the mutual effect of adjacent magnets. Therefore, it is desirable that t/W=0.04 to 0.06.
角柱永久磁石の一端に固着する板状継鉄は、永
久磁石の磁力向上に寄与するが、継鉄厚みＴが厚
すぎるとプレート全体が大型化し、得られる磁力
向上も少ないため、永久磁石高さLmに対して、
Ｔ／Lm＝0.3〜２が望ましい。 A plate-shaped yoke fixed to one end of a prismatic permanent magnet contributes to improving the magnetic force of the permanent magnet, but if the yoke thickness T is too thick, the entire plate becomes large and the obtained magnetic force improvement is small, so the permanent magnet height For Lm,
T/Lm=0.3-2 is desirable.
角柱状永久磁石が４個の場合は、同様の理由に
より以下の条件が望ましい。 When there are four prismatic permanent magnets, the following conditions are desirable for the same reason.
Ｗ／Lm＝1.3〜2.8
ｔ／Ｗ＝0.04〜0.06
Ｔ／Lm＝0.3〜２
