Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は可変目開き二段処理型濾過機に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a variable opening two-stage filter.
平行スリット型濾過装置は樹脂２食品、セラミック、石
油化学等種々の分野で利用されている。Parallel slit type filtration devices are used in various fields such as resin 2 foods, ceramics, and petrochemistry.
この種の濾過装置における目詰まり除去手段として、例
えば、特開昭５６−８７４１４号に示すように、表面に
平行スリットが多数設けられた円筒状エレメントのスリ
ット面を貫いて円筒内外間に原液を流過して粗濾過を行
い、平行スリットの目詰まシは、くしを上記平行スリッ
トに挿入して円筒状エレメントを回動することにより除
去する手段も提案されている。As a means for removing clogging in this type of filtration device, for example, as shown in Japanese Patent Application Laid-Open No. 56-87414, a cylindrical element having many parallel slits on its surface is used to penetrate the slit surface of the cylindrical element and pass the undiluted solution between the inside and outside of the cylinder. A method has also been proposed in which coarse filtration is performed by passing through the parallel slits, and clogging of the parallel slits is removed by inserting a comb into the parallel slits and rotating a cylindrical element.
しかしながら、このような目詰まり除去手段は構造が複
雑でコストが嵩み、目詰まり除去の効果も十分でない。However, such clogging removal means has a complicated structure, is expensive, and is not sufficiently effective in removing clogging.
一般に大径異物及び小径異物を含有する流体を濾過する
場合は、濾過エレメントの細かい目開きは大径異物のた
めにすぐ目詰まりするので、この種の濾過装置には、下
記のような問題がある。Generally, when filtering a fluid containing large-diameter foreign matter and small-diameter foreign matter, the fine openings of the filtration element are easily clogged by the large-diameter foreign matter, so this type of filtration device has the following problems. be.
（１） 原液が大径異物及び小径異物を含有する場合
、頻繁に濾過装置を停止し、目詰まり除去を行わなけれ
ばならない。(1) If the stock solution contains large-diameter foreign matter and small-diameter foreign matter, the filtration device must be stopped frequently to remove clogging.
（２） 目開きが一定で、これを任意に調整すること
ができないので、原液の種類・性状が変化して目開きの
選定を誤まった場合等には、濾過エレメント自体を交換
しなければならないから、その間運転ラインは停止し、
プラントの稼働率が低下する。(2) The mesh opening is fixed and cannot be adjusted arbitrarily, so if the type or properties of the stock solution changes and the mesh opening is incorrect, the filtration element itself must be replaced. During this time, the operating line will be stopped,
Plant availability decreases.
（３）濾過エレメント自体は非常に高価なものであるか
ら、目開きの大小に応じていくつもの濾過エレメントを
揃えておくことは、多大のコストを要する。(3) Since the filtration element itself is very expensive, preparing a number of filtration elements according to the size of the opening requires a large amount of cost.
（４） 目開きの微細な濾過エレメントを製作する場
合、その製作精度は従来余り高くないので、必要とする
目開きよりも細かいものを使用しなければならず、また
製作技術的に肉厚のものを作ることが困難であるために
強度的に良いものが作られていない。(4) When manufacturing a filtration element with a fine mesh opening, the manufacturing precision has not been very high in the past, so it is necessary to use a filter element with a finer mesh opening than the required one, and the manufacturing technology does not allow for thick walls. Because it is difficult to make something, it is not possible to make something with good strength.
（５） 微細な目開きに挾まった異物はその除去作業
が困難で分解しても洗滌は必ずしも容易でない。(5) It is difficult to remove foreign matter trapped in minute openings, and even if it is disassembled, cleaning is not always easy.
そこで、本出願人は、これらの問題点を解決するために

装置の精濾過機構については特願昭６１−２７３１４８
号として特許出願を行った。Therefore, in order to solve these problems, the present applicant first developed a two-stage processing type sieving device in Japanese Patent Application No. 61-28646.
I proposed this as number 1. Briefly, a cylindrical inner screen is formed by stacking a plurality of annular disks coaxially one above the other with the same gap, and the stock solution introduced into the casing is first flowed inward and radially through this inner screen. Among the foreign substances contained therein, large-diameter foreign substances are captured on the outer periphery of the inner screen to perform coarse filtration, and the coarsely filtered stock solution is coaxially extrapolated onto the inner screen with small openings in the radial direction. By flowing outward radially through an outer screen having a similar annular disk structure,
Among the contained foreign substances, small-diameter foreign substances are captured on the inner periphery of the outer screen for precision filtration. At this time, the inner screen is rotated at a slow speed relative to the outer screen, and the captured foreign substances are removed through the respective scraper blades. It is designed to scrape off. Furthermore, the present applicant has filed a patent application No. 61-273148 regarding the fine filtration mechanism of the variable opening type filtration device.
A patent application was filed under the No.
これは同一厚さの異径水平埋板な竪方向に同一すきまを

それぞれの円錐角を同じにし、且つ内側スクリーンを外
側スクリーン内に同軸的に内挿し両者の円錐面間法線方
向のすきまを目開きとし、内側スクリーンを軸方向に移
動させることにより目開きを可変とする構造である。This consists of an outer screen and an inner screen of slightly different sizes, which are horizontally buried boards of the same thickness and different diameters, which are laminated coaxially with the same gap in the vertical direction. The conical angles of the conical surfaces on the outer periphery of the screen are the same, and the inner screen is coaxially inserted into the outer screen, the gap in the normal direction between the two conical surfaces is used as the opening, and the inner screen is moved in the axial direction. It has a structure that allows the opening of the eyes to be varied by changing the size of the opening.
しかしながら前記二段処理型濾過装置では内側スクリー
ンのスリットが一段濾過と二段濾過のν過体を兼ねてい
るため両者の目開きの組み合せのフレキシビリティがな
いこと、さらには内側スクリーンの外面が一段濾過の際

開きの調整に重要な役目を果たしているので、もし万一
この外面が一段濾過の除固い異物等によシ欠損した場合
は、二段濾過の精密濾過に悪い影響を与える等の問題が
ある。However, in the above-mentioned two-stage filtration device, the slits in the inner screen serve as filters for both the first-stage filtration and the second-stage filtration, so there is no flexibility in combining the openings of the two, and furthermore, the outer surface of the inner screen is This outer surface, which is in pressure contact with the scraper during filtration, plays an important role in adjusting the opening of the two-stage filtration, so in the unlikely event that this outer surface is damaged by hard foreign matter etc. in the first-stage filtration, , there are problems such as having a bad influence on precision filtration in two-stage filtration.
本発明は前記出願の濾過装置をさらに改良して一台でも

良い濾過装置を提供するもので原液が大径異物及び小径
異物を含有する場合でも、稼働中にもか＼わらず、目詰

開き二段処理型濾過装置を提供することを目的とする。The present invention further improves the filtration device of the above-mentioned application and provides a filtration device with better performance that has a two-stage processing mechanism and a variable opening mechanism in one unit, and the filtration device has a higher performance than the filtration device in which the stock solution contains large-diameter foreign matter and small-diameter foreign matter. To provide a variable opening two-stage processing type filtration device which can be operated continuously for a long time without causing clogging even during operation.
