さらに、この濾板３には、分離した濾液を外部に排出するため排出路３ｆが濾板本体３ａの下部に設けられて被覆部材の表面に開口するとともに、濾板本体３ａを貫通して底部に開口している。   Further, the filter plate 3 is provided with a discharge passage 3f at the bottom of the filter plate main body 3a for discharging the separated filtrate to the outside, and opens to the surface of the covering member, and penetrates the filter plate main body 3a to the bottom. Is open.

また、被覆部材３ｈの表面には、ネット部材３ｇが設けてあり、濾布７と濾板３との間の濾過液を排出路３ｆに導くようにしてある。   Further, a net member 3g is provided on the surface of the covering member 3h, and the filtrate between the filter cloth 7 and the filter plate 3 is guided to the discharge path 3f.

このような濾板３に適用される濾板構造１０では、ゴムなどの弾性材料の被覆部材３ｈ上に配置される排液促進用の合成樹脂製あるいは金属製のネット部材３ｇの固定をネット固定手段１１〜１４を用いることで、これまでの接着剤で固定する場合などに比べ、簡単かつ確実に取り付けることができるようにしている。   In the filter plate structure 10 applied to such a filter plate 3, fixing of the net member 3 g made of synthetic resin or metal for promoting drainage disposed on the covering member 3 h of an elastic material such as rubber is fixed to the net. By using the means 11 to 14, it is possible to easily and surely attach compared to the case of fixing with an adhesive agent so far.

この濾板構造１０のネット固定手段１１〜１４は、荷重支持用ボス部３ｅへの固定のためのもの１１、枠部材３ｂの周囲への固定のためのもの１２、供給孔３ｄへの固定のためのもの１３，１４のように固定箇所によってそれぞれ異なる。   The net fixing means 11 to 14 of the filter plate structure 10 are for fixing to the load supporting boss 3e, for fixing to the periphery of the frame member 3b, and for fixing to the supply hole 3d. It is different depending on the fixed part like the ones 13 and 14 for the purpose.

まず、荷重支持用ボス部３ｅへのネット固定について、図１および図２により説明する。
濾板３には、鉄製などの円柱状の荷重支持用のボス部３ｅが鉄板製の濾板本体３ａの表裏の濾室３ｃとなる凹部に溶接で複数取り付けられ、これらボス部３ｅおよび濾板本体３ａなどの濾板３全体がゴムなどの弾性被覆部材３ｈで覆われたゴムライニング状態とされ、弾性被覆部材３ｈでゴムライニングされたボス部３ｅを除く濾室３ｃの表裏にそれぞれネット部材３ｇが配置されている。 First, the net fixing to the load supporting boss 3e will be described with reference to FIGS.
A plurality of cylindrical load-supporting bosses 3e made of iron or the like are attached to the filter plate 3 by welding in recesses that become the filter chambers 3c on the front and back of the filter plate main body 3a made of iron plate, and these bosses 3e and the filter plate The entire filter plate 3 such as the main body 3a is in a rubber lining state covered with an elastic covering member 3h such as rubber, and net members 3g on the front and back sides of the filter chamber 3c excluding the boss portion 3e rubber-lined with the elastic covering member 3h. Is arranged.

この荷重支持用ボス部３ｅへのネット部材３ｇのネット固定手段１１では、図１および図２に示すように、ゴムライニングされたボス部３ｅの外径に対応して嵌め込むことができるゴム製のリング状の固定リング部材１１ａが用いられ、側面を円錐面とすることで、底面積を大きくしてネット部材３ｇとの接触面積を大きくし、また円錐形状とすることで濾布の損傷を防止できるようにしてある。また、この固定リング部材１１ａは、高さをゴムライニングされたボス部３ｅより低くしてあり、濾板３を圧締した状態で、固定リング部材１１ａに荷重が作用しないようにしてある。   In the net fixing means 11 of the net member 3g to the load supporting boss portion 3e, as shown in FIGS. 1 and 2, the rubber-made boss portion 3e can be fitted in accordance with the outer diameter of the rubber-lined boss portion 3e. The ring-shaped fixed ring member 11a is used, the side surface is a conical surface, the bottom area is increased to increase the contact area with the net member 3g, and the conical shape is used to damage the filter cloth. It can be prevented. The fixing ring member 11a is lower in height than the rubber-lined boss 3e so that no load acts on the fixing ring member 11a when the filter plate 3 is pressed.

このような固定リング部材１１ａは、ゴムライニングされたボス部３ｅを貫通させることができる取り付け穴が裁断加工されたネット部材３ｇを濾板３の濾板本体３ａのゴムライニングされた表面に取り付けた後、ボス部３ｅに固定リング部材１１ａを嵌め込んで、固定リング部材１１ａの底面とゴムライニングとの間にネット部材３ｇを挟むようにして固定する。このとき、必要に応じて固定リング部材１１ａの底面に接着剤を塗布したり、固定リング部材１１ａの内周面に接着剤を塗布することで、一層確実に固定することができる。   In such a fixing ring member 11a, the net member 3g having a cutting hole cut through the rubber-lined boss 3e is attached to the rubber-lined surface of the filter plate body 3a of the filter plate 3. Thereafter, the fixing ring member 11a is fitted into the boss portion 3e, and the net member 3g is fixed between the bottom surface of the fixing ring member 11a and the rubber lining. At this time, the adhesive can be more reliably fixed by applying an adhesive to the bottom surface of the fixing ring member 11a or applying an adhesive to the inner peripheral surface of the fixing ring member 11a as necessary.

これにより、濾板３を濾布７を介して複数枚重ね合わせて圧締し、脱水処理したり、その後、各濾板３を離間させて濾室３ｃ内の脱水ケーキを落下させる場合でも、安定した状態でネット部材３ｇを濾板３のボス部３ｅで固定することができ、しかも取り付けもゴムなどの固定リング部材１１ａをボス部３ｅに嵌めるだけで簡単にできる。   Thereby, a plurality of the filter plates 3 are overlapped and pressed through the filter cloth 7 and dehydrated, or even when the filter plates 3 are separated and the dehydrated cake in the filter chamber 3c is dropped, The net member 3g can be fixed by the boss portion 3e of the filter plate 3 in a stable state, and the attachment can be simply performed by fitting the fixing ring member 11a such as rubber to the boss portion 3e.

次に、濾板３の枠部材３ｂの内側周囲へのネット固定について、図１および図３により説明する。
濾板３には、略正方形状の鉄板製の濾板本体３ａの表裏の周囲に枠部材３ｂが溶接されて取り付けられて額縁状とされ、この枠部材３ｂの内側の凹部が濾室３ｃとされ、これら枠部材３ｂおよび濾板本体３ａなどの濾板３全体がゴムなどの弾性被覆部材３ｈで覆われたゴムライニング状態とされ、弾性被覆部材３ｈでゴムライニングされた濾室３ｃの表裏にそれぞれネット部材３ｇが配置されている。 Next, net fixing to the inner periphery of the frame member 3b of the filter plate 3 will be described with reference to FIGS.
A frame member 3b is welded and attached to the filter plate 3 around the front and back of a filter plate body 3a made of a substantially square iron plate, and a frame-like recess is formed inside the frame member 3b. The entire filter plate 3 such as the frame member 3b and the filter plate main body 3a is covered with an elastic covering member 3h such as rubber, and the filter chamber 3c is rubber-lined with the elastic covering member 3h. Each net member 3g is arranged.

この枠部材３ｂの内側周囲へのネット部材３ｇの固定のためのネット固定手段１２では、図１および図３に示すように、弾性被覆部材３ｈに枠部材３ｂのゴムライニング面の内側周囲と間隔をあけて濾室３ｃ表面から外側に突き出すように断面矩形の固定用突出部１２ａが一体に形成してあり、枠状に配置されている。なお、この固定用突出部１２ａは、図示例のように、弾性被覆部材３ｈに一体に形成する場合に限らず、濾板本体３ａに鉄板などを溶接して枠状に配置し、これにゴムライニングを施して形成しても良く、強度を一層高めることができる。   In the net fixing means 12 for fixing the net member 3g to the inner periphery of the frame member 3b, as shown in FIGS. 1 and 3, the elastic covering member 3h is spaced from the inner periphery of the rubber lining surface of the frame member 3b. The fixing protrusion 12a having a rectangular cross section is integrally formed so as to protrude outward from the surface of the filter chamber 3c, and is arranged in a frame shape. The fixing protrusion 12a is not limited to being formed integrally with the elastic covering member 3h, as shown in the illustrated example, but a steel plate or the like is welded to the filter plate body 3a and arranged in a frame shape. It may be formed by lining, and the strength can be further increased.

この固定用突出部１２ａには、ゴム製などの固定枠部材１２ｂを嵌め込んでその底面でネット部材３ｇを挟むことができるようにする。
この固定枠部材１２ｂは、その横断面形状が、上下が平行で外側面が垂直面とされ、内側面が傾斜面とされて底面が広く形成され、この底面に開口して固定用突出部１２ａへの嵌め込み孔が形成してあり、嵌め込み孔を固定用突出部１２ａに嵌め込んだ状態で外側面が弾性被覆部材３ｈの内側周囲にも嵌合されるようにしてある。また、この固定枠部材１２ｂは、高さをゴムライニングされた枠部材３ｂより低くしてあり、濾板３を圧締した状態で、固定枠部材１２ｂに荷重が作用しないようにしてある。そして、このような固定枠部材１２ｂは、棒状のものを枠部材３ｂのコーナ部分で４５度の角度で突き合せるようにして接合することで枠状とされる。なお、この枠状とする接合は、取り付け前であっても取り付け時に接合しながら組み付けるようにしても良い。 A fixing frame member 12b made of rubber or the like is fitted into the fixing protrusion 12a so that the net member 3g can be sandwiched between the bottom surfaces thereof.
The fixed frame member 12b has a transverse cross-sectional shape that is parallel in the vertical direction, the outer surface is a vertical surface, the inner surface is an inclined surface, and has a wide bottom surface. The fixing protrusion 12a opens to the bottom surface and is fixed. A fitting hole is formed, and the outer surface is fitted to the inner periphery of the elastic covering member 3h in a state where the fitting hole is fitted into the fixing protrusion 12a. The fixed frame member 12b is lower in height than the rubber-lined frame member 3b so that no load is applied to the fixed frame member 12b in a state where the filter plate 3 is pressed. Such a fixed frame member 12b is formed into a frame shape by joining rod-shaped members so as to abut at an angle of 45 degrees at a corner portion of the frame member 3b. It should be noted that this frame-like joining may be assembled while joining at the time of attachment even before attachment.

このような固定枠部材１２ｂは、ゴムライニングされた固定用突出部１２ａを貫通させることができる取り付け穴が裁断加工されたネット部材３ｇを濾板３の濾板本体３ａのゴムライニングされた表面に取り付けた後、固定用突出部１２ａに固定枠部材１２ｂを嵌め込んで、固定枠部材１２ｂの底面とゴムライニングとの間にネット部材３ｇを挟むようにして固定する。このとき、必要に応じて固定枠部材１２ｂの底面に接着剤を塗布したり、固定枠部材１２ｂの外周面に接着剤を塗布することで、一層確実に固定することができる。   Such a fixing frame member 12b is formed on the rubber-lined surface of the filter plate body 3a of the filter plate 3 by attaching the net member 3g having a cutting hole cut through the rubber-lined fixing protrusion 12a. After the attachment, the fixing frame member 12b is fitted into the fixing protrusion 12a, and the net member 3g is fixed between the bottom surface of the fixing frame member 12b and the rubber lining. At this time, if necessary, an adhesive can be applied to the bottom surface of the fixed frame member 12b, or an adhesive can be applied to the outer peripheral surface of the fixed frame member 12b, so that the fixing can be further ensured.

これにより、濾板３を濾布７を介して複数枚重ね合わせて圧締し、脱水処理したり、その後、各濾板３を離間させて濾室３ｃ内の脱水ケーキを落下させる場合でも、安定した状態でネット部材３ｇを濾板３の周囲で固定することができ、しかも取り付けもゴムなどの固定枠部材１２ｂを固定用突出部１２ａに嵌めるだけで簡単にできる。   Thereby, a plurality of the filter plates 3 are overlapped and pressed through the filter cloth 7 and dehydrated, or even when the filter plates 3 are separated and the dehydrated cake in the filter chamber 3c is dropped, The net member 3g can be fixed around the filter plate 3 in a stable state, and the attachment can be simplified simply by fitting the fixing frame member 12b such as rubber to the fixing protrusion 12a.

次に、濾板３の被濾過物の供給孔３ｄへのネット固定について、図１および図４により説明する。
