Abstract

A cartridge filter assembly is disclosed for a quick and detachable installation in an air filtration system. The cartridge filter assembly comprises a cartridge filter 10 and its mating attachment 20. The mating attachment 20 is suspended from the periphery of an opening 18 in a cell plate 22 of the air filtration system 30. The mating attachment 20 has a periphery tapered from its top to its bottom. The cartridge filter 10 includes a cylinder 10a containing a filtering media and a resilient connector 12 at its top end. The resilient connector 12 has an inner wall defining a receptacle space that is adapted to mate with the tapered periphery of the mating attachment 20. This causes a mating engagement between the inner wall of the connector 12 and the periphery of the mating attachment 20 when the cartridge filter 10 urges the attachment 20 to be in a coaxial relation to it.

Description

1254649 玖、發明說明 發明所屬之技術領城 1 本發明係相關於一種過濾筒,尤其相關於一種能夠輕 易地安裝在空氣過濾系統中並且從空氣過濾系統處移去的 過濾筒。 先前技術 傳統式灰塵收集系統或是空氣過濾系統係被設計以利 用被稱之爲過濾筒或過瀘袋之可個別更換式圓柱形過濾器 以從空氣中移去例如是灰塵以及泥土等微粒物質。此等系 統係具有一個外殼,而外殼係帶有一個用於潔淨空氣之上 方空間以及一個用於包含有將被移除之微粒物質等髒空氣 的下方空間。這兩個空間係藉由一個細胞板或是金屬管片 所分離。細胞板係具有許多開口於其中,而過濾筒係從該 等開口處被懸吊在下方空間之內。 每一個過濾筒係包含一個典型地爲由一過濾材料或媒 介所形成之外部圓筒,以及用於環繞著外部圓筒以防止其 不合意地膨脹之金屬條片。過濾筒亦包含一個支承元件或 結構,用以將其附接至細胞板。 舉例而言,一種傳統支承結構係包含一個帶有凸緣套 蓋之支承元件而被提供有一頂端,以及固定件。過濾筒係 以一種使凸緣套蓋經由例如是螺紋螺栓及螺帽之固定件而 被連接至細胞板的方式,而被插入至細胞板的一個開口之 中並從開口處所垂懸。 另一種傳統支承結構係包含一個被指稱爲一保丨寸件之 1254649 分離式圓柱形支承結構以及固定件。保持件係具有一個凸 緣部分,而此凸緣部分之直徑係較位於其頂端之細胞板之 相應開口以及可插入至過濾筒中之下方部分的直徑爲大。 保持件之下方部分係被插入至細胞板的相應開口之中,並 接著被插入至過減筒之中。接者’該過爐同係藉由例如疋 裝配帶而被固定至保持件處。 然而,爲了更換這些傳統式過濾筒,一個維修人員係 必須屈身或彎腰朝向灰塵收集器的內部’而灰塵收集器的 內部係爲一種髒污環境而可能會致生維修人員之身體及心 理痛苦。 同樣地,以手動方式操作諸固定件(被固定之螺栓以 及螺帽,或是夾鉗帶體)以更換過濾筒係需要複雜的作業 ,並需要在髒污環境中花費大量的時間。 爲了避免涉及固定件之前述問題,受讓予本發明申請 人之日本專利早期公開第2001-269527號係揭示了一種能夠 在不需要固定件的狀況下,而能夠被安裝至灰塵收集器中 、並且能夠從灰塵收集器處移去的過濾筒。此一過濾筒係 具有一個被一體地提供在其頂部端部處的圓柱形部分。圓 柱形部分係爲由一種具彈性之合成樹脂所形成者,並且係 具有一個凸緣部分,而此凸緣部分的直徑係較位於其頂部 端部處之細胞板之相應開口的直徑爲大。過濾筒亦具有一 個具有一已擴張部分之分離式管狀保持件,已擴張部分的 外徑係較圓柱形部分的內徑爲大。爲了將過濾筒安裝在灰 塵收集器之中,其程序係需要以下兩個步驟。首先,圓柱 1254649 形部分係被插入至細胞板的開口之中,用以使凸緣部分與 細胞板於相應開口之周圍處相銜接,以便從該處所垂懸。 其次,管狀保持件係被插入至已垂懸的圓柱形部分之中, 以便藉由已擴張部分來使其伸展。此係會將已垂懸以及已 擴張圓柱形部分帶入一種與開口之內側壁部相互緊密接觸 的狀況中,從而將過濾筒附接至細胞板。 不幸的是,在沒有固定件的狀況下安裝此一過濾筒係 需要施行一種複雜的作業,並且需要花費時間在髒污環境 之中,即使是複雜性或是所花費時間被稍微降低亦然,此 係由於其係需要兩個步驟所致。 因爲過瀘筒係需要週期性地更換,因此存在著一種能 夠輕易地安裝在灰塵過濾器中、並且輕易地從灰塵過濾器 處所移除之過濾筒的需求。 另外,藉由金屬條片所環繞之外側圓柱形元件係典型 地藉由脈衝空氣來加以淸潔,用以將灰塵從其內部處移除 。在脈衝空氣通過外側圓柱形元件之內部時,較佳地,外 側圓柱形元件之內側表面係會經由脈衝空氣而暫時地膨脹 或變形,用以使灰塵及泥土從該處輕易地吹落或逐出,而 灰塵及泥土在沒有此一程序的狀況下係會沉積在其中。然 而,環繞著外側圓柱形元件之金屬條片係會防止此等吾人 所希求之暫時膨脹或變形,並因此灰塵係可能會積聚於其 上。在外側圓柱形元件之內側表面上所產生成層之積聚微 粒物質係會降低過濾筒的過濾能力。 據此,亦存在有一種能夠藉由空氣吹落或逐出微粒物 1254649 質而得輕易地淸潔之過濾筒的需求。 發明內容 本發明之主要目的係爲提供一種過濾筒組件,其係包 含一個附接件以及一個過濾筒。該附接件係具有一個從其 頂部至其底部爲逐漸變細的周圍,並且係適合從一預定位 置處所垂懸。該過濾筒係包含一個包含有一過濾媒介而用 於過濾空氣之圓柱形元件,以及一個被附接至該外側圓柱 形元件之頂端的彈性管狀元件。該彈性管狀元件係具有一 個界定出一個用於一容座之空間的內側壁部。用於一容座 之空間係適合與附接件之逐漸變細的周圍相配,以便使彈 性管狀元件之內側壁部與附接件之逐漸變細的周圍得相配 地銜接,而在同時運用一個迫使過濾筒朝向彈性管狀元件 而成一共軸關係的迫使作用力。介於彈性管狀元件之內側 壁部與附接件之周圍間的相配銜接係可以藉由撤銷迫使作 用力而被分離。 該彈性管狀元件之內側壁部係可以被一體地提供有至 少一個環形脊部,用於容許附接件能夠被卡接在彈性管狀 元件中的適切位置之中。 爲了能夠經由空氣吹落或逐出微粒物質而輕易地淸潔 圓柱形元件,該圓柱形元件之周圍係可以形成爲一摺箱。 摺箱係會繞著圓柱形元件的縱向軸線而圓形地擴張,以使 得圓柱形元件能夠處在一種未擴張或是已擴張狀態之中。 在未擴張或是已擴張狀態之中,一個管狀強化件係被共軸 地容置在圓柱形元件之中。再者,複數個環體元件係被配 1254649 置成大致上平行的諸列於該圓柱形元件的周圍上。每一個 環體元件係於一未擴張狀態中而被裝配在圓柱形元件的周 圍上並帶有爲吾人所希求之一間隙,以便在已擴張圓柱形 元件之已擴張周圍處產生一種環體接觸,用以防止圓柱形 元件之過度擴張。爲了 一體地支承環體元件,長形條片係 從彈性管狀元件處所垂懸,以使其於圓柱形元件的周圍上 被配置成一種大致上平行的諸行。 實施方式 第一圖係顯示出本發明第一實施例之過瀘筒組件的上 方斷面部分。該過濾筒組件係包含一個過濾筒1 〇及其相 配附接件2 0。該過濾筒1 〇係包含一個外側圓柱形元件 1 0 a以及一個位於其上方端部處的彈性管狀元件1 2。 該彈性管狀元件1 2係爲由一種可以包含例如是氨基鉀酸 酯之彈性合成樹脂或是彈性橡膠之適當彈性材料所製成者 〇 該連接器1 2之內側壁部係界定出一個用於容置之空 間。而此空間係具有一個大致上從頂部至底部逐漸尖細之 錐形形狀。較佳地,該連接器1 2之內側表面亦爲成階狀 以一體地提供一個或多個環形脊部1 4及1 6。 該相配附接件2 0係適合於從位於一灰塵收集系統或 空氣過濾系統3 0之一細胞板2 2中之諸開口 1 8 (僅有 一個開口被顯示在第一圖中)之一的周圍處所垂懸。 該相配附接件2 0之周圍係具有一個大致上雒形形狀 ,其係相應於該連接器1 2之用於容置的空間,但其係非 1254649 爲成階者。 在連接器之內側表面中並未包含階狀物之部分的周圍 係稍微較該相配附接件2 0之外側表面的相應部分爲大, 介於這兩個周圍之間的差異係例如是大約2mm至8mm。此 係容許在藉由將一抬昇作用力運用至該過濾筒1 0而將該 過濾筒1 0向上推至該相配附接件2 0 (此一方式將於下 文中予以描述)時,該相配附接件2 0能夠以一種共軸方 式被插入並卡接在該連接器1 2中的適切位置之中。 當該相配附接件2 0被卡接進入該連接器1 2之時, 該相配附接件2 0之外側表面係會藉由使用被產生介於其 與連接器之內側表面間之摩擦或夾鉗作用力來使其彼此相 推,而以一種相配方式與連接器的內側表面相銜接。較佳 地,該相配附接件2 0之周圍以及該連接器1 2的內側壁 部係大致上爲彼此平行者。 此外,如果被提供有藉由被壓縮之脊部1 4和1 6所 產生的彈性抓握作用力,其係會對介於該連接器1 2與該 相配附接件2 0間的相配銜接做出額外貢獻。然而,如果 介於該連接器1 2之內側表面與該相配附接件2 0之外側 表面間的摩擦或夾鉗作用力係足以容許介於其間之一種所 希求相配銜接的話,該脊部1 4和1 6係可以被省略。 當該過濾筒1 0係被推向上至該相配附接件2 0之時 ,介於該過濾筒1 0之連接器1 2與相配附接件2 0之間 的相配銜接係被維持。 藉由如同上述般地施行,一個維修人員係可以依據該 11 1254649 過濾系統3 0之尺寸而藉由僅將其手臂放入至該過濾系統 3 0中爲髒污環境的內部之中,而得輕易且安全地更換該 過濾筒1 0。 此係容許降低維修人員在進行維修時之肉體痛苦或心 理痛苦,並容許降低完成該過濾筒1 0之更換所花去的時 間。同樣地,從該過濾系統3 0處所飛出到達維修人員之 周圍或身上的灰塵係可以被降低。 第二圖至第八圖係顯示出一項設備或一更換裝置4 0 ,其係用於將複數個過瀘筒1 0抬昇至相應附接結構2 2 (在第二圖至第八圖中並未顯示),用以在該空氣過濾系 統3 0之下方部份中進行該過濾筒1 0之更換。 複數個附接件2 0係以一種上文中所描述的方式而從 位於該空氣過濾系統3 0之細胞板2 2 (在第二圖至第八 圖中並未顯示,但顯示於第一圖中)中之諸開口 2 8 (在 第二圖至第八圖中並未顯示,但顯示於第一圖中)的周圍 處所垂懸。 該更換裝置4 0係包含一個可垂直移動式平台4 2, 而複數個將被安裝在該空氣過濾系統3 0中的過瀘筒1 0 係被配置在這些直立位置之中,並且係被固定地彼此分隔 。舉例而言,在此一實施例之中,該過濾筒1 0係於平台 4 2上被配置成一種4 X 3的矩陣形式。 第二圖係顯示出該更換裝置4 0之第一列的前視圖。 其係包含四行過濾筒1 0於平台4 2上,而所顯示之該過 濾筒1 0係爲位於其最下方位置之中。 12 1254649 第三圖係顯示出處在如同於第二圖中所顯示的狀態中 之該更換裝置4 0的側視圖,而在該平台4 2上之第一行 過濾筒係包含三列過濾筒1 0。 該更換裝置4 0亦包含一個用以將該可垂直移動式平 台4 2向上及向下移動之連桿機構4 4、一個用於手動式 操作連桿機構4 4的槓桿4 6、以及一對用於決定用以限 制該連桿機構4 4之移動程度的上方及下方極限位置的止 擋件4 8。 雖然該可垂直移動式之相對端部係被提供有托架5 0 ,如同在第二圖中所顯示者,一個托架5 0係可以在第三 圖中爲吾人所看見而位在第二列的過濾筒1 0下方。如同 在第二圖中所顯示者,該托架5 0係相應於被固定至該空 氣過濾系統3 0之內側壁部處的相配托架5 2 (在第三圖 中並未顯示,但一個相配托架5 2係於第四圖中被顯示爲 一斷面)。當該平台42係爲在最下方位置中之時,如同 在第二圖中所顯示者,每一個托架5 0以及相應的相配托 架5 2係爲彼此堆疊者。 每一個托架5 0以及相配托架5 2係具有一個穿孔( 在圖示中並未顯示出來),用以容置一個穿孔式引導插銷 5 2 a。因此,每一個托架5 0係經由穿孔式引導插銷5 2 a而藉由相應的相配托架5 2以垂直地並且可滑動地被 支承著,用以容許該平台4 2在預定範圍中進行垂直移動 〇 該連桿機構4 4係包含兩對曲柄臂部5 4,其中一對 13 1254649 係被座落在空氣過濾系統3 0的前方,而另一對則係被座 落在空氣過濾系統3 0的後方。該連桿機構4 4亦包含一 個可移動式連接臂部5 6,其係在該空氣過濾系統3 0的 下方前方部分中從該空氣過濾系統3 0的右側延伸至左側 。在該連接臂部5 6的上方,一對從空氣過濾系統3 0之 右側延伸至左側的固定底座5 8係被固定地座落在空氣過 濾系統3 0的前方及後方處(在第二圖以及第三圖中,僅 有後方的固定底座58被顯示出來)。 每一個固定底座5 8之二端部係提供了可旋轉支承件 予一對樞軸6 0 a和6 0 b,該對樞軸6 0 a和6 0 b相 對於固定底座5 8而言係爲正交者。 該曲柄臂部5 4的每一個末梢端部5 4 a係以一種可 樞轉方式被連接至相應的樞軸6 0 a及6 0 b。 如同在第五圖以及第六圖中所顯示之放大部份中,在 該系統3 0的右手邊部份中,該連桿機構4 4亦包含一個 額外臂部5 5,此額外臂部5 5之末梢端部5 5 a係以一 種可樞轉方式被連接至右手邊的樞軸6 0 a (雖然僅有一 個額外臂部5 5,其係可以由一體部件或是分離及對稱部 件所構成)。該額外臂部55之近接端部55b係以一種 可樞轉方式被連接至相應的樞軸6 0 a,以使得額外臂部 5 5係與相應的曲柄臂部5 4 (位於右側者)相合作。 相反地,如同在第七圖及第八圖中的放大部分之中, 該連接臂部5 6的左側端部係以一種可樞轉方式被連接至 該槓桿4 6的末梢端部4 6 a。在接近此一樞轉點處,該 14 1254649 槓桿4 6亦以一種可樞轉方式於位置4 6 b處被連接至相 應的樞軸6 0 b,以便與相應的曲柄臂部5 4 (位於左側 者)相合作。 再者,該曲柄臂部5 4之末梢端部係以一種可樞轉方 式被提供有滾柱5 7。該滾柱5 7係可以在其支承著平台 4 2時於預定範圍之中依循著平台4 2之下方表面。因此 ,該平台4 2、槓桿4 6、曲柄臂部5 4、額外臂部5 5 、以及該連接臂部5 6係形成了一種平行四邊形造型的連 桿,以藉由使該曲柄臂部5 4進行角度旋轉而使4 2進行 向上及向下移動。.在此一平行四邊形造型連桿之中,使該 曲柄臂部5 4進行順時針旋轉係會致使平台4 2之向上移 動,並且致使依循著該曲柄臂部5 4之連接臂部5 6進行 水平移動至左側。相似地,使該曲柄臂部5 4進行逆時針 旋轉係會致使該平台4 2之向下移動,並且致使該連接臂 部5 6進行水平移動至右側。 因爲一個曲柄臂部5 4 (位在系統3 0之左側)係經 由樞軸6 0而以一種可樞轉方式與該槓桿4 6相合作,該 槓桿4 6係可以操作平行四邊形造型的連桿,用以如同下 文中所描述般地將過濾筒安裝在空氣過濾系統之中。 一對相對的止擋件4 8係包含一對相對的板件6 2以 及一對可調整止擋件6 4 (例如是螺紋螺栓),每一個板 件6 2係被固定地座落在鄰近於該連接臂部5 6的每一端 部處,而每一個可調整止擋件6 4係位在每一相對板件6 2上。該對可調整止擋件6 4係可水平移動並且被裝設在 15 1254649 相對板件6 2上,以使其相對於座落在其間之連接臂部5 6而言爲軸向地相對於彼此者。該可調整止擋件6 4相對 於連接臂部5 6的相對位置係界定出連接臂部5 6之水平 移動的限制位置,並因此界定出曲柄臂部5 4之旋轉的限 制位置。每一個可調整止擋件6 4相對於連接臂部5 6的 相對位置係可以被調整至所希求位置處。舉例而言,如果 該可調整止擋件6 4係爲一螺紋螺栓,其位置係可以藉由 使其進行螺動來加以調整。 用於安裝複數個過濾筒1 0於空氣過濾系統3 0中之 更換裝置4 0的操作將於下文中予以描述。 在第二圖以及第三圖之中,該平台4 2係位於其最下 方位置中,以使得每一個托架5 0以及相應的相配托架5 2能夠被堆疊。在此一狀態之中,在第二圖中該槓桿4 6 所座落的左側處,該連接臂部5 6之一端部(左側端部) 係爲從相應止擋件6 4處所分離。在第二圖的右側處,相 對的止擋件6 4係接觸連接臂部5 6之相應端部(右側端 部),以便將該曲柄臂部5 4之旋轉從此一位置處限制至 逆時針方向。 如同上文中所描述及說明於第一圖中者,每一個相配 附接件2 0係從位於該空氣過濾系統3 0之細胞板2 2中 之相應開口 1 8的周圍處所垂懸。複數個過濾筒1 〇係被 置放在該平台4 2上,以便與該附接結構2 2相對準。 如同在第四圖中所顯示者,該槓桿4 6係接著被順時 針地轉動,用以使該曲柄臂部5 4繞著該樞軸6 0而進行 16 1254649 順時針轉動。當該曲柄臂部5 4旋轉之時,該滾柱5 7係 以一種可滑動方式於該平台4 2的下方表面上移動至右側 ,以便抬昇該平台4 2。此係允許該平台4 2上的過濾筒 1 0能夠被推向上至相應的附接結構2 2。 每一個相配附接件2 0係接著被插入至該過濾筒1 〇 的相應連接器1 2之中,並且在相配附接件2 0之外側表 面相配地銜接過濾筒1 0的內側表面之時被保持於其中。 如果該連接器1 2的內側表面係被提供有環形脊部1 4及 1 6,如同在第一圖中所顯示者,則該相配附接件2 0亦 彈性地卡接於其中。 已抬昇之過濾筒1 0係接著經由位在該平台4 2之已 升起位置處的相應連接器1 2,而藉由相應的附接結構2 2以被保持住。該過濾筒1 〇係從而被快速地且輕易地安 裝在該空氣過濾系統3 0 (在第四圖中並未顯示出來)中 。當該平台4 2係位於其已抬昇位置中之時,該曲柄臂部 5 4之更進一步的順時針移動係會被防止,此係因爲位於 左側處的止擋件6 4係會接觸連接臂部5 6所致。在該過 滤筒1 0的使用期間,該平台4 2係被維持在其已抬昇位 置之中。 爲了將該過濾筒1 〇從附接結構2 2處移去,該槓桿 4 6係被逆時針轉動,用以使該曲柄臂部5 4逆時針地繞 者樞軸6 0而轉動,而在同時該滾柱5 7係會以一種可滑 動方式移動於平台4 2的下方表面上以使其下降。當該平 台4 2向下移動之時,該連接器1 2、並因此位於平台4 17 1254649 2上的過濾筒10係會由於其自身之重量而從相應的附接 結構2 2處移去。然而,當該平台4 2係被降低之時,某 些過濾筒1 0係可以仍然被維持在其連接器1 2之中,並 且相應附接結構2 2係由於介於其間之摩擦作用力而會被 相配地銜接。仍然位於附接結構2 2上的過濾筒1 0係可 以被輕易地及手動地拉離連接器1 2處。 在位於下方位置中之平台4 2上的已使用及已移去的 過濾筒1 0係將以新的或是再利用的過濾筒1 0來加以更 換。位於該平台4 2上之新的或是再利用的過濾筒1 0亦 可以經由相同於上述之方式而從顯示於第二圖中的狀態處 被安裝在空氣過濾系統中。 第九圖係顯示出此一發明之過濾筒組件的另一實施例 。過濾筒組件係包含一個過濾筒7 0以及附接件2 0,其 係爲了說明淸楚而並未顯示在第九圖中,但是係被顯示於 第一圖之中。 該過濾筒7 0係包含一個外側圓柱形元件7 0 a,該 圓柱形元件7 0 a的周圍係形成了一個摺箱(bellow),其 係會繞著該外側圓柱形元件7 0 a的縱向軸線而圓形地擴 張,以使得該外側圓柱形元件7 0 a能夠在一種未擴張或 是已擴張狀態之中。該過濾筒7 0亦包含一個圓柱形保持 件7 2,其係被共軸地容置在該外側圓柱形元件7 0 a中 ,以便提供該外側圓柱形元件7 0 a之強化。該外側圓柱 形元件7 0 a係爲由例如是紡粘(spunbond)所製成者。如 同在該外側圓柱形元件7 0 a之頂部中的斷面可看見的, 18 1254649 該保持件7 2係形成一籠狀的網格,其係爲由聚丙烯所製 成者。 該過濾筒7 0亦包含一個彈性圓柱形連接器7 4,其 係相同於第一實施例之連接器1 2,並且係得以一種相同 於上述的方式而可分離地銜接相配附接件2 0 (顯示在第 一圖中)。 在該外側圓柱形元件7 0

to a filter cartridge that can be easily installed in an air filtration system and removed from an air filtration system. Prior art conventional dust collection systems or air filtration systems are designed to utilize particulate, individually replaceable cylindrical filters known as filter cartridges or vials to remove particulate matter such as dust and dirt from the air. . These systems have a housing with a space above the clean air and a space below for containing dirty air such as particulate matter to be removed. These two spaces are separated by a cell plate or a metal tube. The cell plate has a plurality of openings therein, and the filter cartridge is suspended from the openings below the space. Each of the filter cartridges includes an outer cylinder typically formed of a filter material or medium, and a metal strip for surrounding the outer cylinder to prevent it from undesirably expanding. The filter cartridge also contains a support member or structure for attaching it to the cell plate. For example, a conventional support structure includes a support member with a flanged cover and is provided with a top end and a fastener. The filter cartridge is inserted into an opening of the cell plate and suspended from the opening in such a manner that the flange cover is attached to the cell plate via a fixing member such as a threaded bolt and a nut. Another conventional support structure comprises a 1254649 split cylindrical support structure referred to as a containment member and a fixture. The retaining member has a flange portion having a diameter that is larger than a corresponding opening of the cell plate at the top end thereof and a lower portion that can be inserted into the filter cartridge. The lower portion of the holder is inserted into the corresponding opening of the cell plate and then inserted into the reduction tube. The pick-up is fixed to the holder by, for example, a 装配 assembling tape. However, in order to replace these conventional filter cartridges, a maintenance technician must bend or bend over toward the inside of the dust collector. The interior of the dust collector is a dirty environment that may cause physical and psychological pain to the maintenance personnel. . Similarly, manually operating the fasteners (fixed bolts and nuts, or clamp belts) to replace the filter cartridge requires complicated work and requires a lot of time in a dirty environment. In order to avoid the aforementioned problems relating to the fixing member, Japanese Patent Laid-Open Publication No. 2001-269527, which is assigned to the present applicant, discloses that it can be installed in a dust collector without requiring a fixing member. And a filter cartridge that can be removed from the dust collector. This filter cartridge has a cylindrical portion that is integrally provided at its top end. The cylindrical portion is formed of a resilient synthetic resin and has a flange portion having a diameter larger than a corresponding opening of the cell plate at the top end portion thereof. The filter cartridge also has a separate tubular holder having an expanded portion having an outer diameter that is larger than the inner diameter of the cylindrical portion. In order to install the filter cartridge in the dust collector, the program requires the following two steps. First, the cylindrical portion 1254649 is inserted into the opening of the cell plate to engage the flange portion with the cell plate around the respective opening to hang from there. Secondly, the tubular retaining member is inserted into the suspended cylindrical portion to be stretched by the expanded portion. This system will bring the suspended and expanded cylindrical portion into a condition in close contact with the inner side wall portion of the opening to attach the filter cartridge to the cell plate. Unfortunately, installing this filter cartridge without a fixture requires a complicated job and takes time in a dirty environment, even if the complexity or time spent is slightly reduced. This is due to the fact that the system requires two steps. Since the over-cylinder system needs to be periodically replaced, there is a need for a filter cartridge that can be easily installed in a dust filter and easily removed from the dust filter. In addition, the outer cylindrical member surrounded by the metal strip is typically cleaned by pulsing air to remove dust from its interior. When the pulsed air passes through the inside of the outer cylindrical member, preferably, the inner side surface of the outer cylindrical member is temporarily expanded or deformed by the pulsed air to allow dust and dirt to be easily blown off or from there. Out, and dust and dirt will deposit in the absence of this procedure. However, the metal strips surrounding the outer cylindrical member prevent such temporary expansion or deformation as may be desired, and thus dust may accumulate thereon. The formation of a layered accumulation of particulate matter on the inside surface of the outer cylindrical member reduces the filtration capacity of the filter cartridge. Accordingly, there is also a need for a filter cartridge that can be easily cleaned by air blowing or expelling particulate matter 1254649. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a filter cartridge assembly that includes an attachment member and a filter cartridge. The attachment has a periphery that tapers from its top to its bottom and is adapted to hang from a predetermined location. The filter cartridge comprises a cylindrical member comprising a filter medium for filtering air, and an elastic tubular member attached to the top end of the outer cylindrical member. The resilient tubular member has an inner sidewall portion defining a space for a receptacle. The space for a receptacle is adapted to mate with the tapered periphery of the attachment member so that the inner side wall portion of the elastic tubular member mates with the tapered periphery of the attachment member while simultaneously applying one Forcing the filter cartridge to force the force in a coaxial relationship toward the elastic tubular member. A mating engagement between the inner wall portion of the resilient tubular member and the periphery of the attachment member can be separated by reversing the forcing force. The inner side wall portion of the resilient tubular member may be integrally provided with at least one annular ridge for permitting the attachment member to be snapped into a suitable position in the resilient tubular member. In order to be able to easily clean the cylindrical element by blowing or expelling particulate matter through the air, the circumference of the cylindrical element can be formed as a bellows. The bellows is circularly expanded about the longitudinal axis of the cylindrical member to enable the cylindrical member to be in an unexpanded or expanded state. In the unexpanded or expanded state, a tubular reinforcement member is coaxially received in the cylindrical member. Further, a plurality of ring members are arranged to be arranged substantially parallel to the circumference of the cylindrical member. Each of the ring members is assembled in an unexpanded state around the cylindrical member with a gap that is desired for us to create a ring contact at the expanded periphery of the expanded cylindrical member. To prevent excessive expansion of the cylindrical element. In order to integrally support the ring body members, the elongated strips are suspended from the elastic tubular members such that they are arranged in a substantially parallel row around the cylindrical members. Embodiments The first figure shows the upper cross-sectional portion of the over-cylinder assembly of the first embodiment of the present invention. The filter cartridge assembly includes a filter cartridge 1 〇 and its associated attachment 20. The filter cartridge 1 comprises an outer cylindrical member 10a and an elastic tubular member 12 at its upper end. The elastic tubular member 12 is made of a suitable elastic material which may comprise an elastic synthetic resin such as urethane or an elastic rubber. The inner side wall portion of the connector 12 defines one for The space for accommodation. This space has a tapered shape that tapers substantially from top to bottom. Preferably, the inner side surface of the connector 12 is also stepped to integrally provide one or more annular ridges 14 and 16. The mating attachment 20 is adapted to be from one of the openings 1 8 (only one opening is shown in the first figure) located in the cell plate 2 2 of a dust collection system or air filtration system 30 Hanging around the premises. The surrounding attachment member 20 has a substantially dome-shaped shape corresponding to the space for the connector 12 to accommodate, but it is not a 1254649. The circumference of the portion of the inner side surface of the connector that does not include the step is slightly larger than the corresponding portion of the outer side surface of the mating attachment member 20, and the difference between the two portions is, for example, approximately 2mm to 8mm. This allows the filter cartridge 10 to be pushed up to the mating attachment 20 by applying a lifting force to the filter cartridge 10 (this manner will be described below), The mating attachment 20 can be inserted and snapped into a suitable position in the connector 12 in a coaxial manner. When the mating attachment 20 is snapped into the connector 12, the outer surface of the mating attachment 20 will be generated by friction between the inner surface of the connector or the inner surface of the connector. The clamps force them to push each other and engage the inner side surface of the connector in a mating manner. Preferably, the circumference of the mating attachment member 20 and the inner side wall portion of the connector 12 are substantially parallel to each other. In addition, if provided by the elastic gripping force generated by the compressed ridges 14 and 16 , it will be matched between the connector 12 and the mating attachment 20 Make extra contributions. However, if the friction or clamping force between the inner side surface of the connector 12 and the outer side surface of the mating attachment member 20 is sufficient to allow a desired interposition between them, the ridge 1 The 4 and 1 6 series can be omitted. When the filter cartridge 10 is pushed up to the mating attachment 20, the mating engagement between the connector 12 of the filter cartridge 10 and the mating attachment 20 is maintained. By performing as described above, a maintenance worker can obtain the size of the 11 1254649 filter system 30 by placing only his arm into the interior of the filter system 30 in a dirty environment. The filter cartridge 10 is easily and safely replaced. This allows for a reduction in the physical or mental pain of the maintenance personnel during maintenance and allows for a reduction in the time taken to complete the replacement of the filter cartridge 10. Similarly, dust that has flown from the filtration system 30 to the surroundings or to the maintenance personnel can be lowered. Figures 2 through 8 show an apparatus or a replacement device 40 for lifting a plurality of overtubes 10 to respective attachment structures 2 2 (in Figures 2 through 8) It is not shown) for replacing the filter cartridge 10 in the lower portion of the air filtration system 30. A plurality of attachments 20 are from the cell plate 2 2 located in the air filtration system 30 in a manner described above (not shown in the second to eighth figures, but shown in the first figure) The openings 2 8 (not shown in the second to eighth figures, but shown in the first figure) are hung around the middle. The replacement device 40 includes a vertically movable platform 42, and a plurality of overtubes 10 to be installed in the air filtration system 30 are disposed in these upright positions and are fixed. The ground is separated from each other. For example, in this embodiment, the filter cartridge 10 is configured on the platform 42 as a 4 x 3 matrix. The second figure shows a front view of the first column of the replacement device 40. It consists of a four-row filter cartridge 10 on the platform 4 2, and the filter cartridge 10 is shown in its lowest position. 12 1254649 The third figure shows a side view of the replacement device 40 in a state as shown in the second figure, and the first row of filter cartridges on the platform 4 includes three columns of filter cartridges 1 0. The changing device 40 also includes a link mechanism 44 for moving the vertically movable platform 4 2 upward and downward, a lever 46 for manually operating the link mechanism 4 4, and a pair A stopper 48 for determining upper and lower limit positions for restricting the degree of movement of the link mechanism 44. Although the opposite end portions of the vertically movable type are provided with the bracket 50, as shown in the second figure, one bracket 50 can be seen in the third figure for the second position. Column filter cartridge 10 below. As shown in the second figure, the bracket 50 corresponds to a mating bracket 52 that is fixed to the inner side wall portion of the air filter system 30 (not shown in the third figure, but one The mating bracket 52 is shown in a cross section in the fourth figure. When the platform 42 is in the lowermost position, as shown in the second figure, each of the brackets 50 and the corresponding mating brackets 52 are stacked on each other. Each of the brackets 50 and the mating brackets 52 have a perforation (not shown) for receiving a perforated guide pin 5 2 a. Thus, each of the brackets 50 is vertically and slidably supported by the corresponding mating brackets 5 2 via the perforated guide pins 5 2 a for allowing the platform 4 2 to proceed in a predetermined range Vertically moving, the linkage mechanism 4 4 includes two pairs of crank arms 54, wherein a pair of 13 1254649 are seated in front of the air filtration system 30 and the other pair is seated in the air filtration system. 3 0 rear. The link mechanism 4 4 also includes a movable connecting arm portion 5 6 extending from the right side to the left side of the air filtering system 30 in the lower front portion of the air filtering system 30. Above the connecting arm portion 56, a pair of fixed bases 58 extending from the right side of the air filtering system 30 to the left side are fixedly seated in front of and behind the air filtering system 30 (in the second figure) And in the third figure, only the rear fixed base 58 is displayed). The two ends of each of the fixed bases 58 provide a rotatable support to a pair of pivots 60a and 60b, the pair of pivots 60a and 60b being relative to the fixed base 58 For the orthogonal. Each of the distal ends 5 4 a of the crank arms 54 is pivotally connected to respective pivots 60a and 60b. As in the enlarged portion shown in the fifth and sixth figures, in the right-hand portion of the system 30, the link mechanism 4 4 also includes an additional arm portion 5 5 which is an additional arm portion 5 The distal end 5 5 a of the 5 is pivotally connected to the pivot 6 0 a of the right hand side (although there is only one additional arm 5 5 , which may be an integral part or a separate and symmetrical part Composition). The proximal end 55b of the additional arm 55 is pivotally connected to the respective pivot 60a such that the additional arm 5 5 is associated with the corresponding crank arm 5 4 (on the right) Cooperation. Conversely, as in the enlarged portions in the seventh and eighth figures, the left end of the connecting arm portion 56 is pivotally connected to the distal end portion 4 6 a of the lever 46. . Near this pivot point, the 14 1254649 lever 46 is also pivotally connected to the corresponding pivot 6 0 b at position 4 6 b so as to be associated with the corresponding crank arm 5 4 The left side cooperates. Further, the distal end portion of the crank arm portion 54 is provided with a roller 57 in a pivotable manner. The roller 57 can follow the lower surface of the platform 4 2 within a predetermined range as it supports the platform 42. Therefore, the platform 4 2, the lever 46, the crank arm portion 54, the additional arm portion 5 5, and the connecting arm portion 56 form a parallelogram-shaped connecting rod by making the crank arm portion 5 4 Perform an angular rotation to move 4 2 up and down. In this parallelogram-shaped connecting link, causing the crank arm portion 5 to rotate clockwise causes the platform 42 to move upward, and causes the connecting arm portion 56 of the crank arm portion 5 4 to follow. Move horizontally to the left. Similarly, causing the crank arm portion 54 to rotate counterclockwise causes the platform 42 to move downwardly and cause the connecting arm portion 56 to move horizontally to the right. Since a crank arm 54 (located on the left side of the system 30) cooperates with the lever 46 in a pivotable manner via a pivot 60, the lever 46 can operate a parallelogram shaped link. To install the filter cartridge in the air filtration system as described below. A pair of opposing stops 4 8 includes a pair of opposing plates 6 2 and a pair of adjustable stops 6 4 (eg, threaded bolts), each of which is fixedly positioned adjacent thereto At each end of the connecting arm portion 56, each adjustable stop member 64 is seated on each opposing plate member 62. The pair of adjustable stops 64 are horizontally movable and mounted on the 15 1254649 opposing plate member 6 2 such that they are axially opposed to the connecting arm portion 6 6 seated therebetween. Each other. The relative position of the adjustable stop 64 relative to the connecting arm portion 56 defines a restricted position for the horizontal movement of the connecting arm portion 56 and thus defines a restricted position for the rotation of the crank arm portion 54. The relative position of each of the adjustable stops 64 relative to the connecting arm portion 56 can be adjusted to the desired position. For example, if the adjustable stop 64 is a threaded bolt, its position can be adjusted by screwing it. The operation of the replacement device 40 for mounting a plurality of filter cartridges 10 in the air filtration system 30 will be described below. In the second and third figures, the platform 42 is located in its lowermost position so that each of the brackets 50 and the corresponding mating brackets 52 can be stacked. In this state, at the left side where the lever 46 is seated in the second figure, one end portion (left end portion) of the connecting arm portion 65 is separated from the corresponding stopper 64. At the right side of the second figure, the opposite stop member 64 contacts the respective end portion (right end portion) of the connecting arm portion 56 to limit the rotation of the crank arm portion 5 4 from this position to the counterclockwise direction. direction. As described above and illustrated in the first figure, each of the mating attachments 20 is suspended from the periphery of the corresponding opening 18 in the cell plate 2 2 of the air filtration system 30. A plurality of filter cartridges 1 are placed on the platform 42 to align with the attachment structure 22. As shown in the fourth figure, the lever 46 is then rotated clockwise for the crank arm portion 5 to rotate 16 1254649 clockwise about the pivot 60. When the crank arm portion 54 is rotated, the roller 57 is slidably moved to the right side on the lower surface of the platform 42 to lift the platform 42. This allows the filter cartridge 10 on the platform 4 2 to be pushed up to the corresponding attachment structure 2 2 . Each of the mating attachments 20 is then inserted into the corresponding connector 12 of the filter cartridge 1 , and when the outer surface of the mating attachment 20 is matingly engaged with the inner side surface of the filter cartridge 10 Be kept in it. If the inner side surface of the connector 12 is provided with annular ridges 14 and 16, as shown in the first figure, the mating attachment 20 is also resiliently snapped therein. The lifted filter cartridge 10 is then held by the corresponding attachment structure 22 by means of a corresponding connector 12 located at the raised position of the platform 4 2 . The filter cartridge 1 is tethered so as to be quickly and easily installed in the air filtration system 30 (not shown in the fourth figure). When the platform 42 is in its raised position, further clockwise movement of the crank arm 54 is prevented, since the stop 64 on the left side is in contact with the connection. The arm portion 56 is caused. During use of the filter cartridge 10, the platform 42 is maintained in its raised position. In order to remove the filter cartridge 1 from the attachment structure 22, the lever 46 is rotated counterclockwise for rotating the crank arm 54 counterclockwise about the pivot 60. At the same time, the roller 57 is slidably moved on the lower surface of the platform 42 to be lowered. When the platform 4 2 is moved downward, the connector 12, and thus the filter cartridge 10 on the platform 4 17 1254649 2, is removed from the corresponding attachment structure 22 due to its own weight. However, when the platform 42 is lowered, some of the filter cartridges 10 can still be maintained in their connector 12, and the corresponding attachment structure 2 2 is due to the frictional force therebetween. Will be matched to match. The filter cartridge 10, which is still on the attachment structure 22, can be easily and manually pulled away from the connector 12. The used and removed filter cartridges 10 on the platform 4 in the lower position will be replaced with new or reused filter cartridges 10. The new or reused filter cartridge 10 located on the platform 42 can also be installed in the air filtration system from the state shown in the second figure by the same manner as described above. The ninth drawing shows another embodiment of the filter cartridge assembly of the present invention. The filter cartridge assembly includes a filter cartridge 70 and an attachment 20 which are not shown in the ninth figure for purposes of illustration, but are shown in the first figure. The filter cartridge 70 includes an outer cylindrical member 70a, and the periphery of the cylindrical member 70a forms a bellows which is wound around the longitudinal direction of the outer cylindrical member 70a. The axis is circularly expanded such that the outer cylindrical member 70 a can be in an unexpanded or expanded state. The filter cartridge 70 also includes a cylindrical retaining member 72 that is coaxially received in the outer cylindrical member 70a to provide reinforcement of the outer cylindrical member 70a. The outer cylindrical member 70a is made of, for example, a spunbond. As can be seen in the section in the top of the outer cylindrical member 70 a, 18 1254649 the retaining member 7 2 forms a cage-like grid which is made of polypropylene. The filter cartridge 70 also includes a resilient cylindrical connector 74 that is identical to the connector 12 of the first embodiment and that detachably engages the mating attachment 20 in the same manner as described above. (Displayed in the first figure). On the periphery of the outer cylindrical member 70 a, the filter cartridge 70 also includes a plurality of rings 76, which are arranged in a substantially parallel row to prevent the outer cylinder. Over-expansion of the shaped element 70 a. Each of the ring bodies 76 is attached to the periphery of the outer cylindrical member 70a in an unexpanded state with a gap that is desired for us to expand the cylindrical member 7A. A ring contact is created around the expanded area. The gap between us, that is, the gap between the inner side surface of the ring body 76 and the periphery of the outer cylindrical member 70a, may be uniform. Preferably, however, it is desirable for the gap to increase from the end of the outer cylindrical member 70a to gradually extend toward the center on its longitudinal axis. Each of the ring bodies 76 can be, for example, 20 mm wide and 1 mm thick. Around the outer cylindrical member 70a, the filter cartridge 70 also includes a plurality (e.g., four) of elongated flexible strips 78 attached to the loops 76. The filter cartridge 70 is integrally supported. The strips 7 8 are suspended from the connector 74 such that they are arranged in a substantially parallel row around the outer cylindrical member 70 a. Because the strips 7 8 are preferably configured to form a substantially fixed angular separation about the circumference of the outer cylindrical 19 1254649 element 70 a to provide stability of the ring 76, while There are at least three rings 76 in the middle. Furthermore, since the redundant number of strips 7 8 causes the structure and manufacture of the filter cartridge 70 to become complicated, it is desirable that the number of loops 76 can be three to six. Each strip 7 8 can be, for example, 10 mm wide and 0.5 mm thick. In order to reduce the manufacturing cost, the ring body 7 6 and the strip 7 8 are preferably made of the same material, for example, made of nylon or polyester material. Each of the rings 76 can be provided with an adjustable inner diameter which depends on its material (e.g., a polyester material). The filter cartridge 70 can be replaced by the filter cartridge 10 in the first embodiment and can be used in conjunction with the air filtration system 30 in this embodiment. Depending on the amount of use of the filter cartridge 70, the inner side surface of the outer cylindrical member 70a should be periodically cleaned with pulsed air to remove the collected dust. As the pulsed air is blown against the inner side surface of the outer cylindrical member 70a, the bellows around it can be expanded as much as possible without any non-human being caused by the ring 76. It is desirable to intervene because this is due to the fact that the system is provided between the outer cylindrical member 70a and the ring body 76. If the widest gap is positioned at the middle of the outer cylindrical member 70a along its longitudinal axis, the expanded cylindrical member 70a forms a barrel, and the maximum diameter of the barrel is In the middle along its longitudinal axis. Corresponding to the blowing of the pulsed air, the outer cylindrical member 70a can be continuously expanded to make it vibrate. This allows the outer cylindrical member 70a to be effectively deformed to strip or remove dust from the outer cylindrical member 70a. The flexibility of the strip 76 allows the ring 76 to move up or down to follow the expansion of the outer cylindrical member 70a.
