Description
【０００１】[0001]
この考案は、フイルタプレスのろ板のろ過床に敷設するろ材の改良に関する。 The present invention relates to an improvement of a filter material laid on a filter bed of a filter plate of a filter press.
【０００２】[0002]
従来、ろ過の結果生ずるケーキを剥離しやすくするために、弗素系樹脂を用い たろ布は知られており、また、弗素系樹脂は、そのはつ水性、滑り性を利用して 抄紙機に用いられることも、よく知られいてる。 Conventionally, filter cloths using a fluororesin have been known in order to facilitate the exfoliation of cakes resulting from filtration, and the fluororesin is used in paper machines because of its water repellency and slipperiness. It is also well known that it is possible.
【０００３】[0003]
然しながら、上述の弗素系樹脂を用いたろ布は高価である上に、しわ、破れ等 が発生して、その寿命が短いため特殊な需要以外には使用されていない。従来フ イルタプレスはケーキに対して高圧力をかけ得るのでろ過効率が高い利点はある が、ろ材の目に迄ケーキが押し込れる。フイルタプレスでは、このケーキを如何 に剥離してろ過効率のよい運転するかが現在の最大課題となっている。 However, since the filter cloth using the above-mentioned fluorine-based resin is expensive and wrinkles, tears, etc. occur and its life is short, it is not used except for special needs. Conventional filter presses have the advantage of high filtration efficiency because high pressure can be applied to the cake, but the cake is pushed into the eyes of the filter medium. At the filter press, how to remove this cake and operate it with high filtration efficiency is the biggest issue at present.
【０００４】[0004]
この考案は、上述のような実状に鑑みてなされたものであって、この考案では ろ材としてケーキが付着しにくく、然も、強度を有して高圧に耐える金属ろ材を 選定し、このろ材にさらにはつ水性を有する弗素樹脂をコーティングすることに よって剥離性を向上させて、完全にケーキを除去するようにしたものであり、そ の要旨とするところは、フイルタプレスのろ過床に敷設するろ材において、その ろ材を金属フイラメントをネット状に編織して、その金属フイラメントの表面に 弗素樹脂をコーティングしたものである。また、このろ材をろ板に取付けに当っ ては、その周縁にろ板のシール面に設けた一連の溝に嵌着するゴムパッキンを固 着し、そのゴムパッキンを上記溝に嵌着したとき、その上部がシール面から膨出 するようにし、さらに、このろ材をろ板に取付けたとき、その裏面のろ過床上に パンチングメタルよりなる支持部材を設けたものである。 The present invention has been made in view of the above-mentioned circumstances, and in this invention, a metal filter medium that does not easily adhere to a cake as a filter medium and is strong and can withstand high pressure is selected as the filter medium. Furthermore, it is designed to remove the cake completely by coating it with a fluorine resin having water repellency so that the cake can be completely removed. The main point of this is to lay it on the filter bed of the filter press. In the filter material, the metal filament is woven and woven into a net shape, and the surface of the metal filament is coated with a fluororesin. Also, when mounting this filter medium on the filter plate, when the rubber packing that fits in the series of grooves provided on the sealing surface of the filter plate is fixed to the periphery of the filter plate, and the rubber packing is fitted in the groove, The upper part thereof bulges out from the sealing surface, and when this filter medium is attached to the filter plate, a supporting member made of punching metal is provided on the filtration bed on the back side thereof.
【０００５】[0005]
この考案に係るろ材は、上述のように金属フイラメントを編織して、そのフイ ラメントの表面に弗素樹脂がコーティングしてあるので、これをろ板に取付けて 用いる場合、金属であるので従来のろ布に比較して強度を有し、より高圧のろ過 圧力をかけ得るとともに、その表面にコーティングした弗素樹脂が水分を反発し 特に、汚泥ケーキの如く水分を含む原液をろ過する場合には、生じたケーキを反 発してこれを完全に剥離除去することができる。また、弗素樹脂は耐熱性、耐薬 性を有するので、化学工場等の高温で腐蝕性を有する原液のろ過にも使用でき、 フイルタプレスの用途を格別に高め得るものである。以下、図面に基づいてこの 考案の実施例を説明する。 The filter material according to the present invention has the metallic filament knitted and woven as described above, and since the surface of the filament is coated with the fluororesin, when it is attached to the filter plate and used, since it is a metal, it is a conventional filter material. It has strength compared to cloth and can apply a higher filtration pressure, and the fluororesin coated on its surface repels water, especially when filtering a stock solution containing water such as a sludge cake. The cake can be repelled to completely remove it. In addition, since the fluororesin has heat resistance and chemical resistance, it can be used for filtration of a stock solution that is corrosive at high temperatures in chemical plants and the like, which can significantly enhance the use of the filter press. An embodiment of the present invention will be described below with reference to the drawings.
【０００６】[0006]
図１は、この考案に係るろ材をフイルタプレスのろ板に張設した状態の縦断側 面図であり、図中、符号１はろ板で、周縁部にシール面１ａを形成し、中央部を 中凹状にしてその凹部に多数の突起１ｂを設けたろ過床１ｃを形成している。ま た、前期シール面１ａには一連の溝１ｄを設けている。次に、符号２は、ろ過床 ｃに敷設したろ材であって、このろ材２は、金属フイラメントで編成してあり、 その金属フイラメントに弗素樹脂をコーティングするとともに、その周縁に組状 のゴムパッキング２ａを、固着して、このパッキン２ａを前期溝１ｄに嵌着して ろ板に取付けている。そして、このゴムパッキン２ａを溝ｄに嵌着したとき、そ の上部がシール面１ａよりも膨出するようにしてろ板を閉板したとき、ろ板間に 完全にシールされたろ過室を形成するようにしている。また、このろ材２の裏面 にはパンチングメタルよりなる補強シート３が敷いてあってろ材２にかかる高圧 を支えている。尚、図において、符号４はろ液の取出路を示し、原液の供給路は 図示していないが、ろ板を貫通して各ろ板間のろ過室に供給されるものである。 FIG. 1 is a vertical cross-sectional view of a filter plate of a filter press according to the present invention, which is stretched on a filter plate. In the figure, reference numeral 1 is a filter plate, and a sealing surface 1a is formed at a peripheral portion of the filter plate. A filtration bed 1c having a concave shape and having a large number of protrusions 1b formed therein is formed. In addition, a series of grooves 1d are provided on the sealing surface 1a in the previous period. Next, reference numeral 2 is a filter medium laid on the filter bed c, which is knitted with a metal filament, and the metal filament is coated with a fluororesin, and the periphery thereof is assembled into a rubber packing. 2a is fixed, and the packing 2a is fitted in the groove 1d in the previous period and attached to the filter plate. When the rubber packing 2a is fitted in the groove d and the filter plate is closed so that the upper part thereof bulges out beyond the sealing surface 1a, a completely sealed filtration chamber is formed between the filter plates. I am trying to do it. A reinforcing sheet 3 made of punching metal is laid on the back surface of the filter medium 2 to support the high pressure applied to the filter medium 2. In the figure, reference numeral 4 indicates a filtrate take-out path, and a feed path for the stock solution is not shown, but it passes through the filter plates and is supplied to the filtration chamber between the filter plates.
【０００７】 この考案を施したフイルタプレスのろ板は、上述のように構成してあって、こ のように構成したろ板１を多数並列してこれらを閉板して、各ろ板間に形成され る各ろ過室に原液を圧入圧搾して固液分離を行なうものであるが、このとき、こ のろ板１に用いている、ろ材２には弗素樹脂がコーティングしてあるので、圧入 、圧搾の結果生じたケーキが付着することがなく、ろ板１を開板するのみでその ろ過室の下部が開いてケーキは自重で剥離落下して除去することができる。尚、 ろ過床の下部の死角部分等に万一ケーキが残留する場合には、ろ液の取出路４か ら高圧空気を吹き込むことで残留ケーキを除去することができる。すなわち、こ の場合にも弗素樹脂は摩擦係数が極めて小さいので、軽くブローすることで残留 ケーキを剥離除去することができるものである。また、弗素樹脂は、従来のろ布 に比較して耐熱、耐磨耗性を有するとともに、耐蝕性も有するので、各種の原液 の固液分離に使用でき、フイルタプレスの用途を格別に拡大することができるも のである。The filter plate of the filter press to which the present invention is applied is configured as described above, and a plurality of filter plates 1 configured in this way are arranged side by side to close them, and the filter plates are separated from each other. The raw solution is press-fitted and squeezed into each of the filtration chambers formed in 1. to perform solid-liquid separation. At this time, since the filter medium 2 used in this filter plate 1 is coated with a fluororesin, The cake produced as a result of press-fitting and pressing does not adhere, and the lower part of the filtration chamber opens only by opening the filter plate 1, and the cake can be peeled off and dropped by its own weight and removed. If cake remains in the blind spots or the like at the bottom of the filtration bed, it is possible to remove the residual cake by blowing high-pressure air from the filtrate outlet 4. That is, also in this case, since the coefficient of friction of the fluororesin is extremely small, it is possible to peel and remove the residual cake by lightly blowing. In addition, since fluororesin has heat resistance, abrasion resistance, and corrosion resistance compared to conventional filter cloth, it can be used for solid-liquid separation of various stock solutions, expanding the application of filter presses significantly. It is possible.
【０００８】[0008]
このように、この考案に係るフイルタプレスは、弗素樹脂をコーティングした ろ材を用いることによって、従来、剥離困難であったケーキを完全に剥離できる ようにしたものであって、弗素樹脂の耐熱性、耐薬性等と併せてフイルタプレス の性能と用途を別格に向上させ得たものである。 As described above, the filter press according to the present invention uses a filter material coated with a fluororesin so that the cake, which has been difficult to remove in the past, can be completely removed. In addition to chemical resistance, the performance and application of the filter press can be improved exceptionally.
