200831202 九、發明說明 【發明所屬之技術領域】 本發明係關於一種使被噴塗至建築物內之天花板等的 石綿剝離回收之石綿回收裝置。 【先前技術】 爲了提高建築物之耐火特性、絕熱特性、吸音特性等 ❿ ，而在建築物之天花板、牆壁、地板等噴塗石綿。石綿， 雖爲蛇紋岩或角閃石經變形成纖維狀後之天然礦物，但是 已判明一旦將呈現該纖維狀之石綿吸入肺部就會有發生肺 癌等疾病之虞，而造成極大的公害問題。因此，目前，正 . 加緊腳步進行被噴塗至建築物之天花板或牆壁、地板等之 - 噴塗面的石綿之回收作業。 在專利文獻1中，已記載有一種將石綿刮落並予以回 收的石綿吸引裝置之配件。如第4A圖及第4B圖所示，記 • 載於專利文獻1之配件，係具備以可移動之方式設置於車 輪102的架台101;藉由適於該架台101之拘束支撐手段 而被支撐成可進行上下調整的吸入筒104;以與吸入筒 104成爲連通之狀態被安裝於該吸入筒104之前端部的漏 斗1〇5 ;以及設置於漏斗105之內部，且藉由驅動手段對 石綿進行刮除動作的石綿刮除體1 06，.其中，在吸入筒 1〇4連接有從負壓吸引手段開始延伸的吸引軟管103。石 綿刮除體1 06，係將使刮除片1 07a突設於外周一部分的複 數個刮除鼓筒1 07，構成逐個以等角度錯開相位而排列設 200831202 置的狀態，且固設在夾介軸承108軸支於漏斗1〇5之兩側 壁之間的旋轉軸109上。 專利文獻1 ··日本實開平2- 1 2 8 8號公報 ' 【發明內容】 * (發明所欲解決之問題） 若使用專利文獻1中所記載的配件，則藉由石綿刮除 φ 體106旋轉，刮除鼓筒107之刮除片107a就可將石綿從 天花板刮落，而該被刮落的石綿會掉落在漏斗i 〇 5內，並 經過吸入筒104及吸引軟管103而回收至槽等。然而，專 利文獻1中所記載的配件，由於複數個刮除鼓筒1 〇 7係被 . 設置成同軸，所以在因石綿之噴塗量不同而使噴塗面之表 - 面呈現凹凸不平、或天花板之表面呈現凹凸不平或彎曲的 情況，刮除作業就不夠充分，而容易發生刮除殘留現象。 一旦發生該種刮除殘留現象，在消除石綿之刮除殘留現象 • 爲止，就必須在相同的部位進行多次的往復作業，致使作 業效率變差。 因此，本發明之目的在於提供一種即使在石綿被噴塗 之噴塗面有凹凸或彎曲面，亦不會有刮除殘留現象，而可 以一次之刮除作業效率佳地回收石綿的石綿回收裝置。 (解決問題之手段） 本發明之石綿回收裝置，其特徵在於：具備頭部及吸 引手段，其中，該頭部係具備··複數個旋轉體，係於外周 -5- 200831202 面具備用以刮除被噴塗於噴塗面之石棉的刮除手段；及複 數個軸承手段，係分別支撐前述複數個旋轉體；及按壓手 段，係將受到前述軸承構件支撐的旋轉體彈性地壓緊於前 述噴塗面；以及包圍體，係包圍前述複數個旋轉體，該吸 引手段係將前述包圍體內形成負壓，用以吸引被前述刮除 - 手段所刮除掉的石綿。 依據上述構成，按壓手段，係藉由將分別受到軸承手 φ 段支撐的旋轉體彈性地壓緊於噴塗著石綿之噴塗面，俾使 旋轉體以各自獨立之狀態抵接噴塗面。藉此，即使噴塗面 有凹凸或彎曲面，亦可配合該凹凸或彎曲面而排列有旋轉 體。當旋轉體一旋轉，備具於旋轉體之各自的外周面之刮 . 除手段就會刮除噴塗面之石綿，而被刮除掉的石綿會掉落 - 至包圍體。包圍體內，係因藉由吸引手段而形成負壓，所 以被刮除掉的石綿不會飛散至外部而全部會掉落至包圍體 內。 φ 在此，較佳爲，以彈性構件形成刮除手段。 藉由上述構成，就可防止旋轉體藉由按壓手段壓緊於 噴塗面時之刮除手段的破損以及噴塗面的破損。又，藉由 調整按壓手段所帶來的壓緊力，由於可調整刮除手段之彈 性變形量並調整刮除手段之彈性反彈力，所以可輕易調整 石綿之刮除力。 又，較佳爲，複數個旋轉體，係相對於刮除方向，以 成爲千鳥狀之方式複數列排列於前後方向，而與所鄰接的 旋轉體間之離開距離，係配置成比該旋轉體之寬度更窄。 -6 - 200831202 藉由與所鄰接的旋轉體間之離開距離，配置成比該旋 轉體之寬度更窄，俾使排列於後排之旋轉體，位設在排列 於前排之旋轉體彼此間的間隙內，如此就可相對於刮除方 向，無間隙地配置旋轉體，而可防止刮除殘餘現象。 吸引手段，係可具備反應管；及口徑比反應管更小， 用以將高壓流體噴射至反應管內的噴射噴嘴，且該吸引手 段係利用藉由從噴射噴嘴將高壓流體噴射至反應管內所形 成的負壓，將包圍體內形成負壓。 例如，雖然爲人周知者有藉由將從噴塗面刮除所得的 石綿與酸予以混合並使其促進水熱反應，而可分解石綿之 化學結合使其無害化，但是依據本發明，藉由具備上述構 成，則藉由利用將酸等之液體當作高壓流體從噴射噴嘴噴 射至反應管內時所形成的負壓以將包圍體內形成負壓，且 藉由該負壓而將被刮除掉的石綿吸引至反應管內，即可連 續地進行至回收後的石綿之無害化處理爲止。如此，藉由 進行連續的處理，就可容易進行回收後的石綿之處理，並 可成爲更安全的石綿回收裝置。 又，本發明之石綿回收裝置，較佳爲，具備：架台， 係支撐頭部；以及按壓手段，係將頭部彈性地壓緊於噴塗 面，架台，係具備可將該架台朝前後左右移動的移動手段 ;以及可將頭部相對於行進方向朝前後方向移動的導引部 〇 藉由備具於架台之移動手段，架台，就可在設置有噴 塗面的建築物內之地板面朝前後左右移動。然後，頭部， -7- 200831202 由於可藉由備具於架台之導引部而相對於行進方向朝前後 方向移動，所以即使是在因障礙物等而使架台無法前進於 地板面的情況，亦可只使頭部前進。藉此，即使在複雜構 造的建築物內，亦可在不發生刮除殘留現象下，無所不在 地從噴塗面回收石綿。更且，頭部，由於係處於藉由備具 於架台之按壓手段經常彈性地壓緊於噴塗面，且在噴塗面 與頭部上面之間不發生間隙的狀態，所以可防止被刮除掉 的石綿從包圍體漏出而飛散至外部。 (發明效果） 依據本發明，藉由按壓手段將分別由軸承手段所支撐 的複數個旋轉體，以各自獨立之狀態彈性地壓緊於噴塗面 ，則即使在噴塗面有凹凸或彎曲面，亦可以一次之刮除作 業不殘留地刮除回收石綿，且可謀求作業效率之提高。又 ，包圍體內，由於藉由吸引手段而形成負壓，所以不會使 被刮除掉的石綿飛散至外部而可使之掉落在包圍體內，且 可防止作業者因錯誤而吸引石綿、或飛散至建築物內。 【實施方式】 以下，使用圖式就本發明實施形態之石綿回收裝置加 以說明。第1圖係顯示本實施形態的石綿回收裝置中之石 綿回收部分之槪略圖；第2圖係顯示本實施形態的石綿回 收裝置中之無害化裝置部分之槪略圖。第3圖係構成第2 圖之無害化裝置的攪拌管之剖面圖。 -8- 200831202 本實施形態的石綿回收裝置1，係具備頭部1 ο ;藉由 支撐構件17來支撐該頭部10的架台20;以及吸引手段 30 ° 頭部1 〇，係具備：複數個旋轉體11，係於外周面具 備用以刮除被噴塗於噴塗面之石棉的刮除齒1 2 ;以及包圍 體15，係包圍該等複數個旋轉體11。旋轉體11係由中空 之圓柱狀構件所構成，而設置於旋轉體1 1之兩側的軸構 件（未圖示）分別軸支於軸承構件1 3。複數個旋轉體1 1 ，係相對於刮除方向S，以其配置成爲千鳥狀之方式2列 排列於前後方向。又，各自的旋轉體1 1與所鄰接的旋轉 體1 1間之離開距離W2，係配置成比旋轉體1 1之寬度W1 更窄。 刮除齒12,係藉由橡膠等之彈性構件所形成，而其縱 剖面係從基端朝向前端成爲越來越細。又，刮除齒1 2，係 在旋轉體1 1之外周面，以遍及於旋轉體之寬度方向備置 〇 軸承構件13之下端部，係連接於包圍體15之底面。 又，在軸承構件1 3，分別設有將由軸承構件1 3所支撐的 旋轉體11彈性地壓緊於噴塗面之作爲按壓手段的彈簧構 件14。 包圍體1 5，係爲相接於石綿之噴塗面的上面側開口成 平面視大致矩形狀的箱體。在包圍體15前進或後退時， 爲了防止包圍體1 5之上端部接觸到天花板面而捲入內側 ，包圍體1 5之上端部分別成爲緩緩地彎曲於外側的帽遮 -9 -

所不在地從天花板面回收石綿。 如此被刮除掉的石綿，係可從吸引口 34吸引至攪拌 管31內。在此，於藉由噴射噴嘴3 2噴射至攪拌管3 1內 的酸溶液中，藉由從氟化氣體導入管3 7以壓力可被調整 φ 的狀態注入氟化氣體，即可防止從噴射噴嘴3 2所噴射出 的酸溶液之空洞現象的發生’且在能量無損的狀態下，酸 . 溶液會與被吸引的石綿狀況佳地撞擊。藉此，石綿就會一 邊被撞擊破碎成又細又小’而一邊與酸溶液攪拌而推送流 至下游側。如此，隨著藉由被破碎成又細又小使石綿之總 表面積增加，就可在攪拌管3 1內’提高與酸溶液的反應 效率。更且，藉，由在攪拌管31內注入氟化氣體，由於石 綿即使依氟化氣體亦可破碎成又細又小而攪拌’所以可更 進一^步促進石綿的水熱反應。 -16- 200831202 在與酸溶液以及氟化氣體攪拌的狀態下推送流入攪拌 管31內的攪拌物，係一邊依攪拌物彼此間之粒子間撞擊 而更進一步被破碎成又細又小一邊流入攪拌管31內，且 通過管44流入設置有面狀發熱體42的加溫管43。 然後，攪拌物可依面狀發熱體42，而加溫至使水熱反 ’ 應促進的溫度範圍，具體爲30〜180°C左右。然後在被加溫 後的狀態下，通過管47而流至設置有電磁波照射裝置45 φ 的電磁波照射管46。到達電磁波照射管46的攪拌物，係 藉由電磁波照射裝置45而照射電磁波，且藉由來自攪拌 物的粒子內部之發熱而進行水熱反應，攪拌物可在短時間 內成爲無害化。攪拌物，由於成爲在流入上游側之攪拌管 _ 3 1內的過程中被破碎成又細又小的狀態，所以隨著石綿的 總表面積增加，而顯示即使在面狀發熱體42之加溫步驟 或電磁波照射裝置45之電磁波照射步驟中亦爲較高的反 應效率。 # 藉由電磁波照射裝置45而被照射電磁波的攪拌物， 會更進一步流至下游。此時，雖然在攪拌物的表面附著有 .. 未反應物，但是在流至下游側時，由於會與藉由氟化氣體 導入管37而被導入至攪拌管31內的氟化氣體更進一步地 一邊攪拌而一邊流動，所以未反應物可藉此而被溶離，且 攪拌物可被洗淨。又，攪拌物，係在設置於電磁波照射裝 置45之下游側的洗淨裝置50中，藉由來自洗淨液導入口 52的洗淨液之噴射而更加地被洗淨。藉此，附著於攪拌物 之表面的未反應物幾乎會被完全刮除掉，而石綿會成爲無 -17- 200831202 害化的反應物之狀態。 另外，爲了要在噴射噴嘴3 2之下游側容易形成負壓 ，並且提高在攪拌管31內被攪拌的攪拌物之搬運力’可 將攪拌管31以下游側傾斜得比上游側更上方之狀態配置 ，或在攪拌管3 1之下游側連接倒U字型的連結管。藉由 形成該種構成，由於隨著在攪拌管31內進行酸溶液與石 綿之攪拌，會使攪拌物容易在攪拌管31之下游側慢慢地 堵塞攪拌管3 1，所以容易在噴射噴嘴32之下游側形成負 壓，並且可藉由從噴射噴嘴32所噴射的酸溶液之噴射壓 力，以強力的按壓力將攪拌物從攪拌管31推送流至下游 側。 未反應物幾乎完全被刮除掉的攪拌物，係藉由脫水機 60而被固體液體分離。藉由以脫水機60而進行固體液體 分離，固態物即可利用於骨材或塡土、回埋材料等中。又 ，液體成份，亦可在利用循環裝置70回收並藉由過濾器 7 1去除掉細小的固態成份之後，夾介分歧管73供給至貯 留槽3 3以及洗淨液導入口 5 2。 另外’爲了確保藉由電磁波照射裝置45而照射電磁 波的攪拌物之充分的反應時間，其構成亦可在電磁波照射 裝置45與洗淨裝置50之間，或是比洗淨裝置50更下游 側，設置具備有用以攪拌攪拌物的攪拌手段或電磁波照射 手段的保養裝置。 如此，依據本實施形態，藉由彈簧構件1 4，將分別由 軸承構件1 3所支撐的複數個旋轉體n，以各自獨立的狀 -18- 200831202 態彈性地壓緊於天花板面，則即使天花板面有凹凸或彎曲 面，由於旋轉體11亦可各自獨立以沿著天花板面之凹凸 或彎曲面的方式抵接，所以可以一次的刮除作業不殘留石 綿地進行刮除及回收，且可謀求作業效率的提高。又，由 於包圍體1 5內，係藉由吸引手段3 0而形成負壓，所以可 * 使被刮除掉的石綿不飛散至外部而全部掉落在包圍體1 5 內，且可防止作業者因錯誤而吸引石綿、或飛散至建築物 φ 內。 以上，雖已就本發明的實施形態加以說明，但是本發 明的石綿回收裝置並非限於上述實施形態。例如，本實施 形態中，頭部1 〇之旋轉體11雖然有5個排列於前後’但 . 是旋轉體1 1之數目並未限於此，亦可做適當設定。又， 本實施形態中，雖然車輪21係直接配置於架台20之下面 側，但是並無限於此，在天花板面較高的情況，亦可在架 台20與車輪21之間，藉由夾介可支撐架台20以及頭部 φ 1 0之重量的腳部，而將架台20配置得較高。 又，本實施形態中，雖然石綿回收裝置1之吸引手段 3 0係爲無害化裝置1 00的構成之一部分，但是並不限於此 ，亦可形成藉由在吸引泵等連結軟管16，而將包圍體15 內形成負壓，且將被刮除掉的石綿貯留在另外設置的貯留 槽等之構成。然而在該情況，由於在將貯留於貯留槽的石 綿移送至無害化裝置1 〇〇的步驟中，亦有因石綿飛散而損 害作業員的健康之虞，所以較佳爲如本實施形態般，在無 害化裝置100連結軟管16,使無害化裝置1〇〇的構成之一 -19- 200831202 部分發揮作爲吸引手段3 0的功能。藉此，可省略發揮作 爲吸引泵等之吸引手段的功能之裝置，並且可無所不在地 縮小石綿飛散的可能性。 (產業上之可利用性） ^ 本發明係有用作爲回收被噴塗至天花板等的石綿之裝 置。尤其是，較佳地是用作爲即使在噴塗著石綿之噴塗面 _ 有凹凸或彎曲面，亦可沒有刮除殘留現象，以一次之刮除 作業效率佳地回收石綿的石綿回收裝置。 【圖式簡單說明】 , 第1圖係顯示本實施形態的石綿回收裝置中之石綿回 收部分之槪略圖。 第2圖係顯示本實施形態的石綿回收裝置中之無害化 裝置部分之槪略圖。 φ 第3圖係構成第2圖之無害化裝置的攪拌管之剖面圖 〇 第4A圖係習知石綿吸引裝置之整體的槪略側面圖。 第4B圖習知石綿吸引裝置之配件的平面圖。 【主要元件符號說明】 1 :石綿回收裝置 100 :無害化裝置 10 :頭部 -20- 200831202 1 2 :旋轉體 13 :刮除齒 1 4 :彈簧構件 1 5 :包圍體 1 6 :軟管 4 1 7 :支撐構件 1 8 :伸縮裝置 φ 19 :車輪 2 0 :架台 21 :車輪 22 :軌道 30 :吸引手段 3 1 :攪拌管 3 2 :噴射噴嘴 3 3 :貯留槽 # 34 :吸引口 35 :高壓泵 , 3 6 :連結管 3 7 :氟化氣體導入管 3 8 :連結管 3 9 :氟化氣體槽 40 :泵 42 :面狀發熱體 43 :加溫管 -21 200831202 44 :管 45 :電磁波照射裝置 4 6 :電磁波照射管 47 :管 50 :洗淨裝置 ^ 5 1 :洗淨管 52 :洗淨液導入口 ⑩ 53 :管 54 :漿料槽 55 :連結管 56 :泵 60 :脫水機 61 :連結管 7〇 :循環裝置 71 :過濾器 φ 72 :泵 73 :分歧管 •22-BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an asbestos recovery apparatus for peeling and recycling asbestos sprayed onto a ceiling or the like in a building. [Prior Art] In order to improve the fire resistance, heat insulation characteristics, sound absorption characteristics, etc. of buildings, stone wool is sprayed on ceilings, walls, floors, etc. of buildings. Asbestos, although it is a natural mineral after the serpentinite or hornblende has been transformed into a fibrous shape, it has been found that once the fibrous asbestos is inhaled into the lungs, lung cancer and other diseases can occur, causing great public hazard problems. Therefore, at present, it is necessary to step up the recovery of the asbestos that is sprayed onto the ceiling or wall of the building, the floor, etc. Patent Document 1 describes an accessory for a stone attraction device that scrapes off and collects a rock wool. As shown in Figs. 4A and 4B, the accessory included in Patent Document 1 is provided with a gantry 101 that is movably provided to the wheel 102, and is supported by a restraining support means suitable for the gantry 101. a suction cylinder 104 that can be adjusted up and down; a funnel 1〇5 that is attached to the front end of the suction cylinder 104 in a state of being in communication with the suction cylinder 104; and a funnel 105 disposed inside the funnel 105, and the asbestos is driven by the driving means The asbestos scraping body 106 is subjected to a scraping operation, and a suction hose 103 extending from the negative pressure suction means is connected to the suction cylinder 1〇4. The asbestos scraping body 106 is a state in which the scraping piece 107a is protruded from a plurality of scraping drums 107 of a part of the outer circumference, and is arranged in a state in which the phase is shifted by an equiangular angle and arranged in 200831202, and is fixed in the clip. The intermediate bearing 108 is pivotally supported on the rotating shaft 109 between the two side walls of the funnel 1〇5. [Patent Document 1] Japanese Unexamined Patent Application Publication No. Hei No. Hei. No. Hei. No. Hei. Rotating, scraping off the scraper 107a of the drum 107 can scrape the asbestos from the ceiling, and the scraped asbestos will fall into the funnel i 〇 5 and be recovered through the suction cylinder 104 and the suction hose 103. To the slot and so on. However, in the accessory described in Patent Document 1, since the plurality of scraping drums 1 〇 7 are arranged coaxially, the surface of the sprayed surface is uneven or the ceiling is different depending on the amount of the spray of the asbestos. The surface of the surface is uneven or curved, the scraping operation is insufficient, and the scratching phenomenon is liable to occur. Once this kind of scraping residual phenomenon occurs, it is necessary to perform a plurality of reciprocating operations at the same portion to eliminate the residual phenomenon of the asbestos, and the work efficiency is deteriorated. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a asbestos recovery apparatus which can efficiently recover asbestos in a single scraping operation even if the sprayed surface of the asbestos is uneven or curved, and there is no scraping residue. (Means for Solving the Problem) The asbestos collecting device of the present invention includes a head portion and a suction means, wherein the head portion is provided with a plurality of rotating bodies, and is attached to the outer circumference - 5 - 200831202 a scraping means for removing asbestos sprayed on the sprayed surface; and a plurality of bearing means for supporting the plurality of rotating bodies respectively; and pressing means for elastically pressing the rotating body supported by the bearing member to the sprayed surface And the surrounding body surrounds the plurality of rotating bodies, and the attracting means forms a negative pressure in the surrounding body to attract the asbestos scraped off by the scraping means. According to the above configuration, the pressing means elastically presses the rotating body supported by the bearing hand φ section against the spraying surface on which the asbestos is sprayed, so that the rotating body abuts against the spraying surface in an independent state. Thereby, even if the sprayed surface has irregularities or curved faces, the rotating body can be arranged in conjunction with the unevenness or the curved surface. When the rotating body rotates, it is prepared to scrape on the outer peripheral surface of the rotating body. The means removes the asbestos of the sprayed surface, and the scraped stone will fall off - to the surrounding body. By enclosing the body, the negative pressure is formed by the suction means, so that the asbestos that has been scraped off does not scatter to the outside and all fall into the surrounding body. Here, it is preferable to form the scraping means with an elastic member. According to the above configuration, it is possible to prevent breakage of the scraping means and damage of the sprayed surface when the rotating body is pressed against the sprayed surface by the pressing means. Further, by adjusting the pressing force by the pressing means, since the elastic deformation amount of the scraping means can be adjusted and the elastic rebounding force of the scraping means can be adjusted, the scraping force of the asbestos can be easily adjusted. Further, it is preferable that a plurality of rotating bodies are arranged in a plurality of rows in a front-rear direction in a bird-like manner with respect to the scraping direction, and a distance from the adjacent rotating body is arranged to be larger than the rotating body. The width is narrower. -6 - 200831202 is arranged to be narrower than the width of the rotating body by the distance from the adjacent rotating body, so that the rotating body arranged in the rear row is positioned between the rotating bodies arranged in the front row In the gap, the rotating body can be disposed without a gap with respect to the scraping direction, and the scraping residual phenomenon can be prevented. The attraction means may be provided with a reaction tube; and the injection nozzle having a smaller diameter than the reaction tube for injecting the high-pressure fluid into the reaction tube, and the suction means utilizes the injection of the high-pressure fluid from the injection nozzle into the reaction tube. The resulting negative pressure will create a negative pressure around the body. For example, although it is known to those skilled in the art that the asbestos obtained by scraping off the sprayed surface is mixed with an acid and promotes a hydrothermal reaction, the chemical combination of the asbestos can be decomposed to render it harmless, but according to the present invention, With the above configuration, a negative pressure formed when a liquid such as an acid or the like is injected from the injection nozzle into the reaction tube is used to form a negative pressure in the surrounding body, and the negative pressure is to be scraped off by the negative pressure. The dropped asbestos is attracted to the inside of the reaction tube, and can be continuously processed until the asbestos after the recovery is harmless. Thus, by performing continuous processing, the treated asbestos can be easily handled, and it can be a safer asbestos recovery device. Further, the asbestos collecting device of the present invention preferably includes: a gantry that supports the head; and a pressing means that elastically presses the head against the sprayed surface, and the gantry is provided to move the gantry toward the front, back, left, and right a moving means; and a guiding portion that can move the head in the front-rear direction with respect to the traveling direction, by means of a moving means provided on the gantry, the gantry can face the floor in the building provided with the spraying surface Move left and right. Then, the head, -7-200831202, can be moved in the front-rear direction with respect to the traveling direction by being provided on the guide portion of the gantry. Therefore, even if the gantry cannot advance to the floor surface due to an obstacle or the like, It is also possible to just advance the head. Thereby, even in a complicatedly constructed building, the asbestos can be recovered from the sprayed surface ubiquitously without scratching. Moreover, since the head is often elastically pressed against the sprayed surface by the pressing means provided on the gantry, and there is no gap between the sprayed surface and the upper surface of the head, it is prevented from being scraped off. The asbestos leaks from the surrounding body and scatters to the outside. (Effect of the Invention) According to the present invention, the plurality of rotating bodies respectively supported by the bearing means are elastically pressed against the sprayed surface in a state of being independent by the pressing means, even if the sprayed surface has irregularities or curved faces, It is possible to scrape off the recovered asbestos without any residue, and to improve the work efficiency. Moreover, since the negative pressure is formed by the suction means in the surrounding body, the scraped asbestos is not scattered to the outside and can be dropped into the surrounding body, and the operator can be prevented from attracting asbestos due to mistakes, or Scattered into the building.

The caliber is smaller than the agitating tube 31, and is used to inject an acid solution as a high-pressure fluid stored in the storage tank 33 into the stirring tube 31. The suction means is a vacuum which is formed on the downstream side of the injection nozzle 32 by injecting the high-pressure fluid from the injection nozzle 32 into the agitating tube 31, and the hose is clamped from the suction port 34. 16 is to form a negative pressure in the enclosure 15 . The detoxification device 100 of the present embodiment includes a stirring tube 31, a negative pressure formed by an acid solution sprayed by the high pressure pump 35, and suction from the suction port 34 by the rotating body 11. In addition to the asbestos scraped off by the tooth 12, the acid solution and the asbestos are mixed and stirred; the planar heating element 42 is φ, and the stirred and stirred astringent and the acid solution are heated; the electromagnetic wave irradiation device 45, The heated agitated material is irradiated with electromagnetic waves; and the device 50 is used to wash the unreacted material attached to the agitated material irradiated with electromagnetic waves by the electromagnetic wave irradiation device 45 by acid or an alkaline solution or water. And the dehydration machine 60 is a solid liquid separation by the electromagnetic wave irradiated by the electromagnetic wave irradiation apparatus 45, and the stirring material wash|cleaned by the washing apparatus 50. The storage tank 33 is a previously known tank for storing an acid solution which is subjected to a coating operation so that the inner peripheral surface thereof is not sputtered by acid. The storage tanks 3 3 and 11 - 200831202 are connected by a connecting pipe 36, and the connecting pipe 36 is provided with a high pressure pump 35 as described above. As the high pressure pump 35, a previously known high pressure pump such as a plunger pump can be used. As shown in Fig. 3, the agitating tube 31 is provided with an injection nozzle 3 2 for ejecting the eluent stored in the storage tank 33 into the agitating tube 3 1 ; and a fluorinated gas body is injected from the ejection nozzle 3 2 a fluorinated gas introduction pipe 37 in the high-pressure acid solution sprayed; and a suction port 34 as described above. The φ fluorinated gas introduction pipe 37 is disposed on the upstream side of the tip end of the injection nozzle 32 of the agitation pipe 31. The fluorinated gas introduction pipe 37 is connected to the fluorinated gas tank 39 by the connection pipe 38, and the connection pipe 38 is provided with an adjustment to inject the fluorinated gas stored in the fluorination gas tank 39 into the agitation pipe 31. The pump 40 is injected inside the pressure. The fluorinated gas stored in the fluorinated gas tank 39 is introduced into the agitating tube 31 from the fluorinated gas introduction pipe 37 in a state where the injection pressure can be adjusted by the pump 40, and is rotated around the outer circumference of the injection nozzle 32. The flow proceeds to the downstream side to prevent the occurrence of cavitation of the acid solution sprayed from the spray nozzle 32 into the agitating tube 31. The planar heating element 42 is attached to the heating pipe 43 of the stirring pipe 3 1 so as to cover the outer circumferential surface of the heating pipe 43. As the planar heating element 42, although a conventionally known thing can be used, it is preferable to use a planar heating element having p T C (P 〇 s i t i v e T e m p e r a t u r e C 〇 e f f i c i e n t, positive temperature coefficient). Since the PTC planar heat generating system exhibits a uniform temperature distribution, the agitating material flowing into the heating pipe 43 can be uniformly heated by using the PTC planar heat generating body. The heating time of the -12-200831202 of the agitating material by the surface heating element 42 is adjusted by the pressure of the high pressure pump 35, or the surface heating element 42 attached to the heating pipe 43 is changed. Adjust the heating area by the size or number to adjust. The electromagnetic wave irradiation device 45 is provided in an electromagnetic wave irradiation tube 46 to which the interposer 47 is connected to the heating tube 43. In the electromagnetic wave irradiation device 45, an electromagnetic wave that flows into the electromagnetic wave irradiation tube 46 is irradiated with an electromagnetic wave of about 300 MHz to 30 GHz, thereby promoting the hydrothermal reaction of the agitated material, and decomposing the composition containing the Φ heavy metal. Harmless. The cleaning device 50 is composed of a cleaning tube 51 connected to the electromagnetic wave irradiation tube 46 by a clamp tube 53, and a cleaning liquid introduction port 52 provided in the cleaning tube 51. From the cleaning liquid introduction port 52, the acid or the alkali which is the washing water is dissolved. The liquid or water is sprayed into the cleaning tube 51. In the cleaning device 50, the dissolving liquid is ejected by agitating the electromagnetic wave by the electromagnetic wave irradiation device 45, and the unreacted material adhering to the agitated material is dissolved and removed. The agitated material obtained by removing the unreacted material by the cleaning device 50 is temporarily stored in the slurry tank 54. The agitated material stored in the slurry tank 54 is transported to the dehydrator 60 by the pump 56 provided in the connecting pipe 55. The dehydrator 60 is a solid liquid separation by agitating the unreacted material by the cleaning device 50, and a conventionally known product such as a centrifugal separator or a vacuum dehydrator can be used. The dehydrator 60 is connected to the circulation device 70 by the interposing tube 6 1 . In the circulation device 70, the liquid component separated by the dehydrator 60 is recovered and supplied to the storage tank 33 and the cleaning liquid introduction port 52. In the circulation device 70, a filter 71 such as a wedge wire screen (not shown) is provided, whereby the smaller solid content of -13-200831202 contained in the liquid component can be removed. The circulation device 70, the storage tank 33, and the cleaning liquid introduction port 52 are connected to each other via a branch pipe 73, and can be separately supplied by a pump 72. In the present embodiment, the agitating tube 31, the heating tube 43, the electromagnetic wave illuminating tube 46, the cleaning tube 51, and the tubes 44, 47, and 53 function as a reaction tube. Next, the operation of the asbestos recovery device 1 and the detoxification device 1 in the present embodiment will be described. First, the operator carries the asbestos collecting device 1 into a space having a ceiling surface on which the asbestos is sprayed, and arranges the gantry 20 so that the rails 2 2 are parallel to the scraping direction S. Next, the telescopic device 18 is operated by remote control or manual to adjust the height direction of the head 10, and the scraping teeth 1 of the rotating body 1 and the upper opening of the surrounding body 15 are in contact with the ceiling. At this time, the plurality of rotating bodies 1 1 are elastically pressed against the ceiling surface in independent states by the spring members 14 provided in the respective bearing members 13 . Here, even if the ceiling surface has irregularities or curved faces, since the respective rotating bodies 11 can be pivoted in independent states and pressed by the spring members 14, the height direction of the head 10 can be adjusted. When all the rotating bodies 1 1 are in contact with the ceiling surface, the rotating bodies 1 1 can be abutted and arranged along the concave or convex surfaces of the ceiling surface. At this time, depending on the shape of the ceiling surface, although the rotating body 11 which is excessively pressed against the ceiling surface occurs, the rotating body 11 is pressed by the spring member 14 and the scraping teeth 12 are compared with The elastic member such as rubber is formed such that the longitudinal section 14-200831202 is thinner from the base end toward the front end, so that the excessively pressing force can be elastically deformed along the ceiling surface for the excessive pressing force, and can be prevented. The tooth 12 is damaged and the ceiling surface is broken. Further, since the height direction of the head portion 10 is adjusted by the telescopic device 18, and the pressing force of the rotating body 11 is adjusted by the spring member 14, the amount of elastic deformation of the scraping tooth 12 can be adjusted and the scraping tooth can be adjusted. The elastic rebound force of 1 2 makes it easy to adjust the scraping power of the asbestos. Further, the spring member built in the expansion and contraction device 18 can be elastically pressed against the ceiling surface even with the upper side opening portion of the surrounding body 15 and the upper opening portion and the ceiling of the surrounding body 15 Between the faces, there is a slight gap. Once the asbestos recovery device 1 is actuated, the rotating body 1 1 will rotate, and scraping the teeth 1 2 will scrape off the asbestos on the ceiling surface, and the scraped asbestos will fall into the surrounding body 15. At this time, the high pressure fluid is injected from the injection nozzle 32 of the detoxifying device 1 into the agitating tube 31 by the high pressure fluid, and the surrounding body 1 54 is formed by the negative pressure formed on the downstream side of the injection nozzle 32. The inside becomes a negative pressure, so the asbestos that has been scraped off does not scatter to the outside and will all fall into the enclosure 15 . The operator, while rotating the rotating body 1 1 , moves the gantry 20 forward or backward by remote control to recover the asbestos sprayed onto the ceiling surface. Further, the rotating body 1 1 is disposed such that it is narrower than the width W1 of the rotating body 1 1 by the distance W2 from the adjacent rotating body 1 1 , and the rotating body 1 1 arranged in the rear row is set. In the gap between the rotating bodies 1 1 arranged in the front row, since the rotating body 1 1 can be disposed with no gap with respect to the scraping direction S, the scraping residual phenomenon does not occur. The recycling of asbestos can be continued. When the asbestos is recovered from the end of one of the ends and the gantry 20 is advanced or retracted to the other end to complete the collection, the gantry 20 is moved in a certain direction in the left-right direction to further return. Received. Thus, by moving the gantry 20 in space, the asbestos can be recovered ubiquitously. Further, since the support member 17 supporting the head portion 10 can be moved in the front-rear direction with respect to the scraping direction S on the rail 22 provided on the gantry 20, even if the gantry 20 cannot advance to the floor surface due to an obstacle or the like In the case of the case, it is also possible to advance only the head 1 . Thereby, even in a building of a complicated structure, it is possible to recover the asbestos from the ceiling surface without the method of scraping the residual phenomenon. The asbestos thus scraped off can be sucked from the suction port 34 into the agitating tube 31. Here, in the acid solution in the stirring tube 3 1 by the injection nozzle 32, the fluorinated gas is injected from the fluorinated gas introduction pipe 37 in a state where the pressure can be adjusted to φ, thereby preventing the injection. The occurrence of a void phenomenon in the acid solution ejected from the nozzle 3' and in the state of non-destructive energy, the acid solution will collide with the attracted asbestos condition. Thereby, the asbestos is crushed into a fine and small one by the impact while being stirred with the acid solution and pushed to the downstream side. Thus, as the total surface area of the asbestos is increased by being broken into fine and small, the reaction efficiency with the acid solution can be increased in the stirring tube 31. Further, by injecting a fluorinated gas into the agitating tube 31, since the ash can be broken into fine and small and stirred by the fluorinated gas, the hydrothermal reaction of the asbestos can be further promoted. -16- 200831202 The agitating material that has flowed into the agitating tube 31 while being stirred with the acid solution and the fluorinated gas is further broken into fine and small sides while stirring according to the interparticle collision between the agitating materials. Inside the tube 31, the tube 44 flows into the heating tube 43 provided with the planar heating element 42. Then, the agitating material can be heated to a temperature range in which the heat of the water is promoted in accordance with the surface heating element 42, specifically, about 30 to 180 °C. Then, in the state after being heated, the tube 47 flows to the electromagnetic wave irradiation tube 46 provided with the electromagnetic wave irradiation device 45 φ. The agitating material that has reached the electromagnetic wave irradiation tube 46 is irradiated with electromagnetic waves by the electromagnetic wave irradiation device 45, and hydrothermal reaction is performed by heat generation inside the particles from the agitating material, whereby the agitated material can be rendered harmless in a short period of time. The agitated material is broken into a fine and small state in the process of flowing into the agitating tube _ 31 on the upstream side, so that the total surface area of the asbestos increases, and the heating of the planar heating element 42 is displayed. The step or the electromagnetic wave irradiation step of the electromagnetic wave irradiation device 45 also has a high reaction efficiency. # The agitated material that is irradiated with electromagnetic waves by the electromagnetic wave irradiation device 45 flows further downstream. At this time, although the unreacted material adheres to the surface of the agitated material, it flows further to the fluorinated gas introduced into the agitation tube 31 by the fluorinated gas introduction pipe 37 when flowing to the downstream side. The ground flows while stirring, so that the unreacted material can be dissolved by this, and the agitated material can be washed. Further, the agitated material is further washed by the ejection of the cleaning liquid from the cleaning liquid introduction port 52 in the cleaning device 50 provided on the downstream side of the electromagnetic wave irradiation device 45. Thereby, the unreacted material adhering to the surface of the agitated material is almost completely scraped off, and the asbestos becomes a state of the reactant which is not harmful to -17-200831202. In addition, in order to easily form a negative pressure on the downstream side of the injection nozzle 32, and to increase the conveying force of the agitating material stirred in the agitating pipe 31, the agitating pipe 31 can be inclined to the downstream side from the upstream side. Arrange or connect the inverted U-shaped connecting pipe to the downstream side of the stirring pipe 31. By forming such a configuration, the stirring of the acid solution and the asbestos in the stirring tube 31 causes the agitating material to easily block the stirring tube 3 1 on the downstream side of the stirring tube 31, so that it is easy to be in the spray nozzle 32. A negative pressure is formed on the downstream side, and the agitating material can be pushed from the agitating tube 31 to the downstream side with a strong pressing force by the injection pressure of the acid solution ejected from the injection nozzle 32. The agitated material in which the unreacted material is almost completely scraped off is separated by the solid liquid by the dehydrator 60. By separating the solid liquid by the dehydrator 60, the solid material can be used in aggregates, alumina, embedding materials, and the like. Further, the liquid component may be recovered by the circulation device 70 and the fine solid component is removed by the filter 71, and then the intervening manifold 73 is supplied to the storage tank 33 and the cleaning liquid introduction port 52. In addition, in order to ensure a sufficient reaction time of the agitating material that irradiates electromagnetic waves by the electromagnetic wave irradiation device 45, the configuration may be between the electromagnetic wave irradiation device 45 and the cleaning device 50 or on the downstream side of the cleaning device 50. A maintenance device having a stirring means or an electromagnetic wave irradiation means for stirring the stirring material is provided. As described above, according to the present embodiment, the plurality of rotating bodies n supported by the bearing members 13 are elastically pressed against the ceiling surface by the spring members 14 in the independent state of -18-200831202, even if The ceiling surface has irregularities or curved surfaces, and the rotating body 11 can be independently abutted along the concave or convex surface or the curved surface of the ceiling surface, so that the scraping operation can be scraped and recovered without residual stone dust in one time. Seek to improve work efficiency. Further, since the negative pressure is formed by the suction means 30 in the surrounding body 15, the stone dust which is scraped off can be scattered to the outside without being scattered to the outside, and all can be prevented from falling into the surrounding body 15 and the operation can be prevented. The person attracts asbestos due to mistakes or flies into the building φ. Although the embodiment of the present invention has been described above, the asbestos collecting device of the present invention is not limited to the above embodiment. For example, in the present embodiment, the number of the rotating bodies 11 of the head portion 1 is five or more in the front and rear. However, the number of the rotating bodies 11 is not limited thereto, and may be appropriately set. Further, in the present embodiment, the wheel 21 is disposed directly on the lower surface side of the gantry 20, but it is not limited thereto. When the ceiling surface is high, the pylon 20 and the wheel 21 may be interposed therebetween. The gantry 20 and the foot of the weight of the head φ 10 are supported, and the gantry 20 is disposed high. In the present embodiment, the suction means 30 of the asbestos collection device 1 is a part of the configuration of the detoxification device 100. However, the present invention is not limited thereto, and the hose 16 may be connected by a suction pump or the like. A negative pressure is formed in the surrounding body 15, and the asbestos scraped off is stored in a separately disposed storage tank or the like. However, in this case, since the step of transferring the asbestos stored in the storage tank to the detoxification device 1 is also caused by the scattering of the asbestos, the health of the worker is also impaired. Therefore, as in the present embodiment, The hose 16 is connected to the detoxification device 100, and one of the components -19-200831202 of the detoxification device 1A functions as the attraction means 30. Thereby, it is possible to omit the device functioning as a suction means for attracting a pump or the like, and it is possible to omnipresently reduce the possibility of asbestos scattering. (Industrial Applicability) ^ The present invention is useful as a device for recovering asbestos sprayed onto a ceiling or the like. In particular, it is preferably used as a asbestos recovery apparatus which can efficiently recover asbestos in a single scraping operation, even if the sprayed surface of the asbestos is coated with irregularities or curved surfaces.
