【考案の詳細な説明】
この考案は、ポンプの押込圧力で脱水したのち、さらに
、ダイアフラムで高圧圧搾脱水をするようにしたフィル
タフ゜レスにおけるダイアフラムの固定装置の改良に関
する。[Detailed Description of the Invention] This invention relates to an improvement of a fixing device for a diaphragm in a filter filter, which performs dehydration using the pushing pressure of a pump and then performs dehydration by high-pressure compression using the diaphragm.
近年、脱水後の焼却や運搬のための経費を節減するため
に高圧搾，高脱水の可能なフィルタプレスが要求される
が、ダイアフラムはゴムで構ｅ，されているがために、
芯板へ締付ける場合や、高圧力をかけた場合に変形する
。In recent years, in order to reduce the cost of incineration and transportation after dehydration, there has been a demand for filter presses capable of high compression and high dewatering, but because the diaphragm is made of rubber,
It deforms when tightened to the core plate or when high pressure is applied.
この考案は、このダイアフラムの取付構造に関するもの
で、上述のような場合に変形することがなく、給液等に
支障の生じない固定装置を実現したものである。This invention relates to the mounting structure of this diaphragm, and is intended to realize a fixing device that does not deform in the above-mentioned cases and does not cause problems in liquid supply, etc.
以下、図面に随って、この考案を詳述すれば、先ず、そ
の構或は、圧搾式フィルタプレスにおいて、ダイアフラ
ム１を取付けるための芯板２の原液供給口３の周辺に、
リング状の突条４を設け、その突条４にダイアフラム１
に穿設した開口５を外嵌すると共に、該部分におけるダ
イアフラム１を口金６と芯板２とで以て扶持したもので
ある。Hereinafter, this invention will be described in detail with reference to the drawings. First, in the structure or squeeze type filter press, around the stock solution supply port 3 of the core plate 2 to which the diaphragm 1 is attached,
A ring-shaped protrusion 4 is provided, and a diaphragm 1 is attached to the protrusion 4.
An opening 5 drilled in the opening 5 is fitted onto the outside, and the diaphragm 1 in the opening 5 is supported by a base 6 and a core plate 2.
尚、図中符号７は濾板、８は濾板７に取付けた給液口金
、９はその原液の通路を示す。In the drawing, reference numeral 7 indicates a filter plate, 8 indicates a liquid supply cap attached to the filter plate 7, and 9 indicates a passage for the stock solution.
この考案は、上述のように構戊してあり、原液は、原液
供給口３から通路９を経て、濾板７とダイアフラム１と
の間に構或される濾室１０に送り込まれ、続いてダイア
フラム１と芯板２の間に高圧水を送り込むことにより、
ダイアフラム１が膨張して瀘室１０内のケーキが圧搾さ
れる。This device is structured as described above, and the stock solution is sent from the stock solution supply port 3 through the passage 9 to the filter chamber 10 constructed between the filter plate 7 and the diaphragm 1, and then By sending high pressure water between the diaphragm 1 and the core plate 2,
The diaphragm 1 expands and the cake in the filter chamber 10 is squeezed.
このダイアフラム１を膨張させたときに、第３図に示す
ような従来のものでは、その開口５部分が図中上方に引
張れて伸びて原液供給口３内に引込れる。When the diaphragm 1 is inflated, in the conventional diaphragm 1 shown in FIG. 3, the opening 5 is stretched upward in the figure and drawn into the stock solution supply port 3.
このように伸張したダイアフラム１は、圧力を取去って
も復元せず、原液の供給を阻害する。The diaphragm 1 that has been stretched in this way does not recover even after the pressure is removed, and thus impedes the supply of the stock solution.
また、圧搾圧力をかけないで単にダイアフラムを芯板に
取付けるためにねじ等で締付けるのみでも、その変形分
が原液供給口３内に突出して原液の供給を阻害する。Further, even if the diaphragm is simply tightened with a screw or the like to attach it to the core plate without applying compression pressure, the deformed portion protrudes into the stock solution supply port 3 and obstructs the supply of stock solution.
このような場合、この考案では、前述のように、芯板２
の原液供給口３の周辺にリンク状の突条４が設けられて
あり、この突条４にダイアフラム１に穿設した開口５を
外嵌するようにしてあるので、この突条４がダイアフラ
ム１を取付ける場合、ガイドになると共に、ダイアフラ
ム１を膨張させた場合にも、原液供給口３内に引込れる
ことがなく、従って、圧搾圧を格段に高めることができ
る。In such a case, in this invention, as mentioned above, the core plate 2
A link-shaped protrusion 4 is provided around the stock solution supply port 3, and an opening 5 formed in the diaphragm 1 is fitted onto the protrusion 4, so that the protrusion 4 is connected to the diaphragm 1. When the diaphragm 1 is attached, it acts as a guide and even when the diaphragm 1 is expanded, it will not be drawn into the stock solution supply port 3, so that the squeezing pressure can be significantly increased.
従来、この種フィルタプレスでの圧搾圧力は、給液部分
のシール構造や上述したようなダイアフラムの変形等か
らして１５ ｋｇ／ｃｍ２が限界であったのであるが、
この考案に依れば、上述のようにして３０ ｋｇ／ｃｍ
２以上の高圧圧搾を可能としたものであり、しかも、そ
の構造は芯板にリング状の突条を附すのみであるので、
製作も容易に行うことができる。Conventionally, the compression pressure in this type of filter press was limited to 15 kg/cm2 due to the seal structure of the liquid supply part and the deformation of the diaphragm as described above.
According to this invention, as described above, 30 kg/cm
It is capable of high pressure compression of 2 or more, and its structure is only that a ring-shaped protrusion is attached to the core plate.
It is also easy to manufacture.
このように、この考案は、高圧搾型フィルタプレスに用
いて卓効を奏するものである。In this way, this invention is highly effective when used in high-pressure type filter presses.
