近年來，瀝青設備，除了製造瀝青合成材之新合成 材設備之外，要求設置製造再生合成材或排水性合成 材的附加設備者，其所需要的設置面積亦變成更大’ 故選擇設置場所變成愈來愈困難。 先前，著眼於配置瀝青設備之構成裝置’對儘量地 縮小所需要的設置面積下種種的功夫’但對於上述構 成裝置之中佔有大的所需要設置面積的混合塔本體與 構材乾燥裝置（乾燥機），其僅對裝置之配置下功夫’ 特別是，對具備上述附加設備的瀝青設備實不能充分 地減少所需要的設置面積。 瀝青設備之構成裝置中的構材乾燥裝置’係將長尺 寸圓筒狀之旋轉鼓輪配置其縱方向爲橫向者’故以可 減短其長度的分量’僅其分量可使本身之所需要設置 面積小之外，與供應構材於構材乾燥裝置的構材漏斗 884 五、發明説明（2 ) 之間距離亦變短，良好地減少全體上.所需要的設置面 積變成可能。

本構材乾燥裝置A，具備有：具再生構材用鼓輪 (第一旋轉鼓輪）1及新構材用鼓輪（第二旋轉鼓輪）2， 而該等位於同軸線上而排成一列，且結合爲一體的旋 轉鼓輪3 ;分別於再生構材用鼓輪1之一端部與另一 端部（第1、2圖爲左端部與右端部），以包圍再生構 材用鼓輪1設置的冷岐管4及熱漏斗5 ;分別於新構 材用鼓輪2之一端部與另一端部（第1、2圖爲左端部 與右端部），以包圍新構材用鼓輪2裝置的冷漏斗6 及熱漏斗7 ;設於熱漏斗7的燃燒器8 ;連終於再生 構材用鼓輪1之一端側供應再生構材於鼓輪1內的再 生構材投入裝置9 ;連絡於新構材用鼓輪2之一端側 供應新構材於鼓輪2內的新構材投入裝置1 〇 ;具備 燃燒器1 1的脫臭爐1 2 ;以及集塵裝置1 3。 上述旋轉鼓輪3，係具備1個圓筒狀之鼓輪依設於 -6- 482884 五、發明説明（5 ) 縱方向中央的隔壁3 a所區劃的上述再生構材用鼓輪 1，與新構材用鼓輪2者，並使上述再生構材用鼓輪 1側變高予傾斜軸線。而且旋轉鼓輪3，係嵌於其外 周的鐵輪3 b，3 b載置於設在支撑台1 4的輥子1 5 a、 1 5 b，以周方向旋轉自如地支撑於支撑台丨4。在支撑 台1 4藉由上述輥子1 5 a，1 5 b固定由電動機等所成， 用來旋轉旋轉鼓輪3的旋轉驅動裝置1 6 ◦ 又，於上述再生構材用鼓輪1之另一端側，以沿周 方向連通上述熱漏斗5開設複數個穿通孔h 1，經加 熱乾燥的再生構件成爲從設於熱漏斗5下部的排出口 5 a排出。在上述新構材用鼓輪2之一端側，以沿周 方向連通上述冷漏斗6開設複數個穿通孔h2，並從 上述新構材投入裝置1 0形成將新構材投入鼓輪2內。 再者，在上述再生構材用鼓輪1與新構材用鼓輪2 之內周面，分別從各鼓輪1，2之下部g 1舀上來再生 構材與新構材於上部g 2使其落下的刮板1 7，在各個 周方向與軸方向隔以適宜間隔安裝有複數個。 上述刮板1 7係如第2圖所示，位於再生構材、新 構材之投入側（各構材移送方向E之上游側），亦即， 再生構材用鼓輪1與新構材用鼓輪2 —端側的各刮板 構件1 8，以平行設於各鼓輪1，2之軸方向。又，位 於再生構材，新構材之排出側（各構材移送方向E之 下游側）’亦即，再生構材用鼓輪1與新構材用鼓輪 2另一端側的各刮板構件1 9，設成將各構材推回上游 482884 五、發明説明（6 ) 側方向傾斜。亦即，刮板構件1 9，係僅以傾斜角度 β (參照第4圖）使下游側端部1 9a比上游側端部1 9b ’先行於各鼓輪1，2之旋轉方向口側地傾斜。又， 各-刮板1 7，形成大致U字狀的橫剖面而延長於各鼓 輪1 ’ 2之縱方向，固定各刮板1 7 —方（基端側）之側 邊部1 7 a於各鼓輪1，2之內壁面。再者，各刮板1 7 之底部邊1 7 b朝向各鼓輪1，2之大致中心方向，且 各刮板1 7之另一方（自由端側）側邊部1 7 c係朝向各 鼓輪1，2之旋轉方向F。 而且’於所傾斜的各刮板構件1 9之自由端側邊部 1 9c ’在其縱方向沿該縱方向隔以適宜間隔穿通開設 複數個長開縫1 9 d。 上述作傾斜的各刮板構件i 9，並不是僅在各鼓輪i ’ 2之軸方向爲丨群，設複數群也可以。在此情形， 以各彼此群間互相在各鼓輪1 , 2之旋轉方向可予對 齊相位’或偏移相位，又，從上游側者往下游側者亦 可使傾斜角度0漸漸變大。更於各刮板1 7 ,係省略 平行的刮板1 8 ’可構成全部爲傾斜的刮板1 9。在此 情形’亦與上述同樣自上游者往下游者漸漸地使傾斜 角度0變大。 上述再生構材用鼓輪（第一旋轉鼓輪）丨與新構材用 鼓輪（第二旋轉鼓輪）2，分別設定爲對其直徑D的長 度L之比（L/D)變成15〜2·5之範圍。 上述比（L/D)在1.5以下的範圍時，使各鼓輪1，2 482884 五、發明説明（7 ) 內邊被加熱乾燥而移送於軸方向，在其再生構材或新 構材之各鼓輪1，2內的滯留時間亦成過短，使上述 再生構材或新構材之乾燥度變成不適合於製造瀝青合 成材者。又，上述比（L/D)超過2.5的範圍時，各鼓 輪1，2之長度變長，各鼓輪1，2之表面積變大，來 自壁面之發散熱多，增加由燃燒器的消耗燃料。 雖然上述再生構材用鼓輪1與新構材用鼓輪2，係 以具有同一直徑者來構成，亦可互相形成爲不同直徑 ，亦在其情形，對各個直徑D的長度L之比（L/D)， 當然乃設定於上述之範圍。 上述冷岐管4真有上部設再生構材投入口 4a的滑 槽4b，在端面部具熱風導入口 4c而固定於上述支撑 台1 4，使上述再生構材用鼓輪1之一端側以各上述 鼓輪1之施轉來關閉。 又，上述熱漏斗5在下部具排出口 5 a，上部設具 防霧過濾器5 b的排氣箱5 c，並以容許再生構材用鼓 輪1之旋轉地固定於上述支撑台1 4。 上述冷漏斗6在上部具排氣箱6a，排氣箱6a之側 部設滑槽6b，並以容許新構材用‘鼓輪2之旋轉固定 於上述支撑台1 4。 上述熱漏斗7在下部具排出口 7a，端面部具熱風 導入口 7b而固定於上述支撑台14，使上述新構材用 鼓輪2之另一端側以容許該鼓輪2之旋轉地關閉。 上述再生構材投入裝置9，由帶式輸送機等構成， 482884 五、發明説明（8 ) 而上端部連終於上述冷岐管4之再生構材投入口 4 a。 又’新構材投入裝置1 0係由帶式輸送機1 a，投入 升降機1 Ob等所成而連絡於上述冷漏斗6之滑槽6b。 上述脫臭爐1 2，係自上述熱漏斗5之排氣箱5 c， 藉由設送風機2 1與馬達控制之擋板2 2的送氣導管 2 0導入排氣氣體.，形成以燃燒器1 1來燃燒排氣氣體 中之殘存煙霧。又，於脫臭爐1 2之排出口，分別藉 由具有開閉調整自如之擋板2 3 a、2 4 a的分岐導管2 3 、24，連接上述冷岐管4之熱風導入口 4c與上述熱 漏斗7之熱風導入口 7b。 上集塵裝置1 3由袋過濾器所成，係藉由具開閉調 整自如地排氣檔板2 5 a、2 6 a的排氣導管2 5、2 6，連 接於其上游側爲上述熱漏斗5之排氣箱5 c及上述冷 漏斗6之排氣箱6 a。 在上述集塵裝置1 3之下游側，由具有馬達控制的 擋板2 7及排風機2 8的吸引導管2 9連接煙囪3 0。 其次’說明依如上述構成的瀝青設備之構材乾燥裝 置之作用。 同時加熱乾燥再生構材與新構材時，旋轉旋轉鼓輪 3 ’同時作動上述再生構材投入裝置9及新構材投入 裝置1 0 ’再作動上述熱漏斗7之燃燒器8及脫臭爐 1 2之燃燒器1 1。然後，分別將來自脫臭爐1 2之熱風 邊送入再生構材用鼓輪1，來自燃燒器8及脫臭爐1 2 之熱風邊送入新構材用鼓輪2，將再生構材邊經由投 -10- 482884 五、發明説明（9 ) 入口 4 a及滑槽4 b，使新構材經由滑槽6 b分別投入 各鼓輪1，2。投入於各鼓輪1，2的構材（再生構材 、新構材），係自上游側一邊移送於下游側一邊被加 熱乾燥，分別從上述熱漏斗5之排出口 5 a，上述熱 漏斗7之排出口 7a排出。以各構材之加熱乾燥作動 所排出的排氣氣體，由排風機2 8流通於集塵裝置1 3 來淨化，從煙囱放出於大氣。 於上述，對再生構材用鼓輪1投入其一端側（上游 測）的再生構材，由反覆殼在其內周的刮板1 7於再生 構材用鼓輪1之下部被舀上來，於上部被落下，依序 ，進行朝另一端側，（下游側）移送，被接觸於來自脫 臭爐1 2之熱風所加熱乾燥。其時，設於上述刮板1 7 下游側的刮板構件1 9，因傾斜於往上游側推回再生 構材方向，於再生構件用鼓輪1之下游側則朝再生構 件，下游之移送速度變成緩慢，可充分地確保在再生 構材用鼓輪1內的的再生構材之滯留時間。 而且，在傾斜的上述刮板構件1 9，因於側邊部1 9 c 設置開縫1 9 d，故刮板構件1 9沿再生構材用鼓輪1 之同方向上升的期間，再生構材係以底邊部1 9 c漸漸 地被回至原上游側，從上述開縫1 9 d形成落下於鼓輪 1之下部，再生構材之落下膜（落下分佈）變成均勻。 再者，由於對鼓輪1直徑D的長度L之比（L/D)設 定在1 · 5〜2 · 5之範圍，將鼓輪1之直徑D設定大，則 可使上述再生構材落下膜之寬大，故良好地進行再生 -11- 482884 五、發明説明（10 ) 構件對熱風的接觸。 因此，依上述再生構材用鼓輪1，如上述對鼓輪1 之直徑D的長度L之比（L/D)設定在較習知者小的 1 · 5〜2.5之數値範圍時，亦可確實地供給得以製造良 好瀝青合成材的乾燥度之再生構件。 尙，同時與依上述再生構材的再生構材之加熱乾燥 ，投入於新構材用鼓輪2的其一端上側的新構材，係 伴隨該鼓輪2之旋轉朝下游側邊依序移送邊被加熱乾 燥，可是其時在新構材用鼓輪2內的新構材之加熱乾 燥作用，係與上述再生構材用鼓輪1之情況相同，故 省略其說明。‘ 於上述，加熱乾燥再生構材的包含煙霧分量之排氣 氣體，係於上述熱漏斗5排出箱5 c之空氣淸淨過濾 器5 b除去煙霧分量後，通過排氣導管2 5，作動於新 構材之加熱乾燥與流自排氣導管2 6的排氣氣體合流 被集塵裝置1 3吸引，除去粉塵。因此，更完全地除 去排氣氣體中之煙霧或粉塵外，以袋過濾器使用爲集 塵裝置1 3時，亦予減輕其網目堵塞。 又’於上述’開啓擋板22作動送風機2 1，則通過 上述淸空制過濾器5b的排氣氣體通過送氣導管20送 入脫臭爐1 2之燃燒室，在此予燃燒殘存煙霧。因此 ’予以防止由煙霧的臭氣公害。 往脫臭爐1 2的排氣氣體之循環量，係以調整擋板 22與排氣擋板2..5&之開閉度或調整送風機2 1之運轉 -12- 482884 五、發明説明（11 ) 速度來調整之。又，在脫臭爐1 2產生的熱風對於再 生構材用鼓輪1與1新構材用鼓輪2之分配量，係依調 整擋板23a、24a之開閉度來調整。 尙，於上述，係使用再生構材用鼓輪1與新構材用 鼓輪2之雙方，說明了加熱乾燥再生構材與新構材的 情況，可是亦可以關閉排氣導管2 6之排氣檔板2 6 a 與分岐導管2 4之擂板2 4 a，同時停止新構材投入裝 置1 〇 ’由將再生構材供給於再生構材用鼓輪1用來 僅加熱乾燥再生構材。又，關閉排氣導管2 5之排氣 擋板25a與各分岐導管23、24之擋板23a、24a及送 氣導管2 0之擋板2 2，同時停止脫臭爐1 2之燃燒器 1 1作動與再生構材投入裝置9，由於將新構材供給於 新構材用鼓輪2可僅加熱乾燥該新構材者。 其次，第5圖表示本發明第2實施形態的瀝青設備 之構件乾燥裝置B。 第5圖之構件乾燥裝置B，係如上述第1實施形態 之構材乾燥裝置A，係將旋轉鼓輪3不以結合再生構 材用鼓輪1與新構材用鼓輪2爲一體者，而以別體來 構成兩鼓輪1，2者。而且，再生構材用鼓輪（第一旋 轉鼓輪）la與新構材用鼓輪（第二旋轉鼓輪）2a，分別 由電動機（旋轉驅動裝置）1 6 a、1 6 b藉由以獨立旋轉驅 動的輥子1 5 c、1 5 d以旋轉自如地支撑於支撑台1 4。 其他之構成係與上述第一實施形態者相同，故同樣 之構成部分附與同樣符號省略其說明。 -13- 482884 五、發明説明（12 ) 依本第2實施形態之構材乾燥裝置B，除了發揮與 第1實施形態之構材乾燥裝置A同樣的作用效果之 外，發揮如次之作用效果。 亦即，再生構材用鼓輪（第一旋轉鼓輪）1 a與新構材 用鼓輪（第二旋轉鼓輪）2a可以獨立地驅動，故不需要 使用一方之鼓輪時，停止其鼓輪之運動，可以另一方 鼓輪2之單獨運轉來作業，能謀求省能量化。又’以 一方鼓輪作保養檢查、修繕等期間，在另一方之鼓輪 可以繼續作業，故能有效率地運轉構材乾燥裝置。再 者，在修繕時的更換鼓輪，因各個鼓輪係其長度短’ 故可容易進行更換作業。 尙，於第2實施形態之構材乾燥裝置B，係與第1 實施形態之構材乾燥裝置A時同樣，將再生構材用 鼓輪1 a與新構材用鼓輪2 a，構成爲配置該等之軸線 在同一線上，但在於將再生構材用鼓輪1 a與新構材 用鼓輪2 a以獨立地驅動者，並不一定要構成如上述 者。構成兩鼓輪1 a，2 a之軸線分別在同樣傾斜方向 而同樣傾斜角度，或配置在2個不同的線上之構成也 可以。又，配置爲如傾斜方向互相相反而同樣的傾斜 角度或者在不同線上亦可。於該等之情況，依傾斜成 爲高位置的各鼓輪1 a，2 a之端部側設構材（再生構材 、新構材）之投入口，成爲底位置之端部側設構材之 排出口，使構材從高位置側移送至低位置側。 其次，第6圖表示本發明第3實施形態的瀝青設備 -14- 482884 五、發明説明（13 ) 之構材乾燥裝置c。 第6圖之構材乾燥裝置C，係將再生構材用鼓輪 (第一旋轉鼓輪）1 a與新構材用鼓輪（第二旋轉鼓輪）2 a 分別由各個之支撑台支撑，用來倂設於瀝青設備者。 其他之構成係與上述各實施形態之構材乾燥裝置A ，B相同。故同一構成部分附與同一之符號省略其說 明。 依本實施形態之構材乾燥裝置C，除了發揮與上述 各實施形態之構材乾燥裝置A，B同樣的作用效果之 外，因應於設置場所之狀況，可適宜地設定再生構材 用鼓輪1 b與新構材用鼓輪2 b的配置。 依上述第1、第2、第3實施形態之構材乾燥裝置 A，B，C，至少在再生構材用鼓輪（第一旋轉鼓輪）1 ，：la，lb與新構材用鼓輪（第二旋轉鼓輪）2，2a，2b 的一方，對旋轉鼓輪直徑D的長度L之比（L/D) ’設 定於比習知之構材乾燥裝置小的數値1.5〜2.5之範圍 ，故構材乾燥裝置之旋轉鼓輪3之全長變短，僅其分 量可使構材乾燥裝置之所要設置面積小，同時鼓輪之 表面積亦小，減少自鼓輪外壁面之發散熱，能實現了 省能化。欲設置構材乾燥裝置於高架台上時，使架台 之長度縮短來謀求其小型化，可大幅度地削減製作費° 接著，例如對於旋轉鼓輪之直徑D = 2 . 1 m，長度 L = 8m之習知新構材用鼓輪（鼓輪容積27.7m3)，以同 樣鼓輪容積，設定依本案發明的新構材用鼓輪’設# -15- 482884 五、發明説明（14 ) 旋轉鼓輪之直徑D = 2.6 m，則長度爲L = 5.2 m ’ L/D = 2.0 ，旋轉鼓輪之長度L比習知者短2·διη 〇又， 對於習知旋轉鼓輪之表面積5 2.8 m2，依本案發明的 新構材用鼓輪之表面積爲4 2.5 m2，以習知比就減少 了約1 9.5 %。此減少的表面積分量乃有助於減少從鼓 輪壁之散熱，依實際上之運轉結果，由於使用依本發 明的新構材用鼓輪，確認了比習知者謀求提高 5〜1 0 %熱效率，獲得省能量效果。 第7圖，將上述第1實施形態之構材乾燥裝置A 或第2實施形態之構材乾燥裝置B，用以比較設置於 瀝青設備時（第7(A)圖）之構材乾燥裝置設置面積S1 ’與個別地支撑習知之再生構材用鼓輪和新構材用鼓 輪於支撑台的構材乾燥裝置，倂設於瀝青設備時（第 7(B)圖）的構材乾燥裝置之設置面積S2者。從第7圖 即可明白，本發明之第1或第2實施形態之構材乾燥 裝置’係比較習知之構材乾燥裝置，可大幅度的減少 設置面積（約減少4 0 % )。 尙於第7圖’ 2y係習知乾燥加熱裝置之再生構材 用鼓輪，3 1係瀝青設備之混合塔，3 2係再生骨材之 儲藏裝置，3 3係附設於再生構材用鼓輪2 y的燃燒室 。其他之符號，係已在上述各實施形態之構材乾燥裝 置A，B說明的構成因素者相同。 又，於上述旋轉鼓輪3之內部，將再生構材或新構 件以推回某移送方向之上游側方向設有傾斜地刮板 -16- 482884 五、發明説明（15 ) 19，故如上述，對鼓輪直徑D的長度L之比（L/D)設 定爲比習知者小時，充分確保了在再生構材或新構材 之旋轉鼓輪3內的滯留時間，可獲得於製造瀝青設備 合成材需要地所要之乾燥度。 接著，實際運轉上述習知之新構材用鼓輪（旋轉鼓 輪之直徑D = 2.1m，長度L = 8m，L/D = 3.8)，及依上述 本願發明的新構材用鼓輪（旋轉鼓輪之直徑D = 2.6m， 長度L = 5.2m，L/D = 2)，用來比較旋轉鼓輪內構材之 滯留時間下構材之乾燥度（乾燥後構材之殘留含水比） w ’結果對於習知之新構材用鼓輪T = 2 1 8秒，w = 0 . 〇 2 〜0.0 6 %，依本發明的新構材用鼓輪，其旋轉鼓輪之 L/D儘管比習知者小，但於構材之滯留時間，乾燥度 確認了與習知者無遜色。 尙，於上述實施形態，旋轉鼓輪3均具備再生構材 用鼓輪1，1 a，1 b及新構材用鼓輪2，2 a，2 b，並構 成爲加熱乾燥再生構材與新構材之雙方或者該等之一 方者，但是構成爲僅具備再生構材用鼓輪、新構材用 鼓輪之一方，作爲僅將再生構材，新構材之一方單獨 地加熱乾燥的構材乾燥裝置亦可以。在此情況，亦可 使所要構材乾燥裝置之設置面積小，能謀求省能量化。 [產業上之利用可能性] 如以上所說明，依本發明的瀝青設備之構材乾燥裝 置，對旋轉鼓輪直徑D的長度L之比（L/D)設定爲 1.5〜2.5之範圍，故使旋轉鼓輪爲一定容積時，與習 -17- 482884 五、發明説明（16 ) 知者比較，因可以減短長度L增大直徑D ’所以由刮 板舀上於上部的構材之落下膜之寬度廣大，旋轉鼓輪 之長度短時亦良好地進行構材對熱風的接觸，可獲得 所要之乾燥度。 再者，旋轉鼓輪之長度短的分量可減小構材乾燥裝 置之所要設置面積。 因此，使瀝青設備選擇其設置場所不會受到限制， 能容易地設置。 [參考符號說明] 1 · —— • •再 生 構 材 用 鼓輪（第 一旋 轉 鼓輪） 2· • _新 構 材 用 鼓 輪（第二 旋轉 鼓 輪） 3 · · · • •旋 轉 鼓 輪 · · · 岐 管 5· • •熱 漏 斗 6 · · • •冷 漏 斗 8,11.....燃燒器 9· •再生構材投入裝置 1〇. · · ·

Description of the invention (1) [Technical Field] The present invention relates to a structure drying device for asphalt equipment, which is used to dispose of new structure materials and paving wastes (recycled materials) generated in accordance with a road control overlaying project. To be dried and heated. [Technical Background] Asphalt equipment is installed near the place where the road is paved. It is ideal that the manufactured asphalt composite material can be quickly supplied to paving machinery. However, it cannot be installed in a narrow land because of the large installation area required. Sites are restricted and sometimes cannot be located near the road construction site. In recent years, asphalt equipment, in addition to new synthetic material equipment for the manufacture of asphalt composite materials, requires installation of additional equipment for manufacturing recycled composite materials or drainage composite materials. The required installation area has also become larger. Becomes more and more difficult. Previously, attention was paid to the arrangement of the asphalt equipment's constituent devices 'to reduce the required installation area as much as possible'. However, the mixing tower body and the structural material drying device (drying device) occupying a large required installation area among the above-mentioned constituent devices. Machine), which only works on the configuration of the device '. In particular, the required installation area cannot be sufficiently reduced for the asphalt equipment provided with the above-mentioned additional equipment. The structural material drying device in the constituent device of the asphalt equipment is a long cylindrical drum which is arranged horizontally in the longitudinal direction. Therefore, the component that can shorten its length is only the component that can make it necessary. In addition to the small installation area, the distance to the structural funnel 884 that supplies structural materials to the structural drying device V. Invention description (2) is also shortened, which reduces the overall size. The required installation area becomes possible. The conventional structure drying device is a structure in which the material is heated and dried by the combustion gas of the burner while moving from one side to the other side while the structure material is repeatedly moved up and down by the scraper in the rotating drum. The length L of the drum is sufficient to ensure the stagnation time of the structure in the rotating drum, so as to obtain the dryness of the structure suitable for the manufacture of asphalt composite materials. Ratio (L / D); {ϊ, ji is practically set to a range of ~ 5. '手 ㊅ — In general, the departure time T of the structural material is given by T = kxL / (DxSdxN) (k: coefficient, sd: rotation of the rotation and rotation of the wheel, N: rotation number of the rotating drum) If the installation area of the structural material drying device is small, and the length-to-length ratio (L / D) of the diameter of the rotating drum is made small, it can be understood from the above formula. The residence time T ratio of the structural material becomes shorter, The desired dryness of the structure cannot be obtained. Therefore, in the conventional structure drying device, the length-to-length ratio (L / D) of the diameter of the rotating drum is smaller than the above-mentioned range. Making the setting area smaller does not help reduce the asphalt equipment. The problem of the area to be set.

In the structure drying device of the asphalt equipment which is heated and dried by the hot air sent into the rotary drum, the rotary drum set its length-to-diameter ratio. For the range of 1, .5- ^ 2. 5 and 0, the ratio (L / D) of the length L of the structure dry device y to the diameter D of the rotating drum (L / D) is set to 1.5 to 2.5. The range is therefore to rotate the drum to make its volume be-timing. Compared with the known person, j can shorten the length L and increase the diameter D 〇 Therefore, the area lifted by the scraper blades in the area above the rotating drum (the width of the falling film of the material) becomes wider. When: turn i turn i drum i wheel, the: When the length L is short, the structure: The contact of the material to the hot air is good: go well: get it. The required dryness j while rotating the length L of the drum at the same time makes the flat area of the structural drying device (the area to be set becomes smaller Q [0] Brief description] FIG. 1 is a system diagram of a structural material drying device of an asphalt plant according to a first embodiment of the present invention.

A rotation drive device 16 for rotating the rotary drum 3 is fixed on the support table 14 by the above-mentioned rollers 15a, 1b, and is fixed to the roller 1 of the recycled structural material. On one end side, a plurality of through holes h 1 are opened so as to communicate with the thermal funnel 5 in the circumferential direction, and the heat-dried regeneration member is discharged from a discharge port 5 a provided at a lower portion of the thermal funnel 5. A plurality of through holes h2 are opened at one end side of the new structural material drum 2 to communicate with the cold funnel 6 in the circumferential direction, and the new structural material input device 10 is formed to put the new structural material into the drum 2. Furthermore, on the inner peripheral surfaces of the regenerated structural drum 1 and the new structural drum 2, the regenerated structural material and the new structural material are respectively formed on the upper g 2 from the lower portion g 1 of each of the drums 1 and 2. A plurality of squeegee blades 17 are mounted at appropriate intervals in each of the circumferential direction and the axial direction. The above-mentioned scraper 17 is located on the input side of the recycled structural material and the new structural material (upstream side of each structural material transfer direction E) as shown in FIG. 2, that is, the drum 1 for the recycled structural material and the new structural material. Each of the scraper members 18 on the end side of the drum 2 is provided in parallel to the axial direction of each of the drums 1, 2. Also, each scraper is located on the other end side of the recycled structure material and the discharge side of the new structure material (the downstream side of each structure material conveying direction E). The member 19 is set to push each member back to the upstream 482884. V. Description of the invention (6) The side direction is inclined. That is, the squeegee member 19 is such that the downstream end portion 19a precedes the upstream side end portion 9b 'at the inclination angle β (refer to FIG. 4) ahead of the rotation direction of each drum 1,2. tilt. In addition, each of the scrapers 17 is formed in a substantially U-shaped cross-section and extends in the longitudinal direction of each drum 1 ′ 2 to fix each scraper 17 to the side (base end side) 1 7 a. On the inner wall of each drum 1,2. In addition, the bottom edge 17b of each scraper 17 is directed toward the approximate center of each drum 1, 2 and the other (free end side) side edge portion 17c of each scraper 17 is toward each drum. Rotation direction F of wheels 1, 2. In addition, a plurality of long slits 19d are formed in the free end side portions 19c of each of the inclined squeegee members 19 in the longitudinal direction at appropriate intervals along the longitudinal direction. The above-mentioned inclined squeegee members i 9 are not limited to a group only in the axial direction of each drum i '2, but a plurality of groups may be provided. In this case, the rotation directions of the drums 1 and 2 can be aligned or offset 'with each other, and the inclination angle 0 can be gradually increased from the upstream side to the downstream side. Further, each of the squeegee plates 17 can be formed by omitting the parallel squeegee plates 1 8 '. In this case, as described above, the inclination angle 0 gradually increases from the upstream to the downstream. The regenerated structural drum (first rotating drum) 丨 and the new structural drum (second rotating drum) 2 are each set so that the ratio L (D / D) of the length L to the diameter D becomes 15 The range is ~ 2.5. When the above-mentioned ratio (L / D) is in the range of 1.5 or less, the drums 1, 2 and 482884 are used. 5. The inner side of the invention is dried by heating and transferred in the axial direction. The residence time in each of the drums 1 and 2 is too short, so that the dryness of the above-mentioned recycled or new structure becomes unsuitable for the manufacture of asphalt composite materials. When the ratio (L / D) exceeds the range of 2.5, the length of each of the drums 1,2 becomes longer, the surface area of each of the drums 1,2 becomes larger, and more heat is radiated from the wall surface, which increases the consumption by the burner. fuel. Although the above-mentioned regenerated structural drum 1 and new structural drum 2 are constructed with the same diameter, they can also be formed with different diameters from each other. In this case, the ratio of the length L of each diameter D ( L / D), of course, is set in the above range. The cold manifold 4 really has a chute 4b provided with a recycled structural material input port 4a at the upper part, and has a hot air inlet 4c at the end surface portion, and is fixed to the support table 14 so that one end side of the recycled structural drum 1 The above-mentioned rotation of the drum wheel 1 is turned off. The heat hopper 5 is provided with a discharge port 5 a at the lower portion and an exhaust box 5 c with an anti-fog filter 5 b at the upper portion. The heat hopper 5 is fixed to the support base 1 4 to allow rotation of the drum 1 for regenerating structural materials. . The cold hopper 6 is provided with an exhaust box 6a on the upper side, and a chute 6b is provided on the side of the exhaust box 6a, and the new structure is fixed to the support table 14 by the rotation of the 'drum 2'. The heat funnel 7 is fixed to the support base 14 with a discharge port 7a at the lower portion and a hot air introduction port 7b at the end portion, and the other end side of the drum 2 for the new structural material is closed to allow the drum 2 to rotate. The above-mentioned recycled structural material input device 9 is composed of a belt conveyor or the like. 482884 V. Description of the invention (8) The upper end portion is finally connected with the recycled structural material input port 4a of the cold manifold 4. The new structure material input device 10 is a belt conveyor 1 a and an elevator 1 Ob, which are connected to the chute 6b of the cold hopper 6 described above. The deodorizing furnace 12 is an exhaust box 5 c from the thermal funnel 5, and the exhaust gas is introduced through the air supply duct 20 of the blower 21 and the motor-controlled baffle 2 2 to form a burner 1. 1 to burn the residual smoke in the exhaust gas. In addition, the outlets of the deodorizing furnace 12 are connected to the hot air introduction port 4c of the cold manifold 4 and the branching ducts 2 3 and 24 through baffles 2 3 a and 2 4 a which can be adjusted freely. The hot air inlet 7b of the hot funnel 7. The upper dust collecting device 13 is formed by a bag filter, and is provided with an exhaust duct 2 5 a, 2 6 of an exhaust baffle plate 2 5 a, 2 6 a which can be freely adjusted. The upstream side is connected with the above heat. The exhaust box 5 c of the hopper 5 and the exhaust box 6 a of the cold hopper 6 described above. On the downstream side of the dust collecting device 13 described above, a suction duct 29 is connected to the chimney 30 by a baffle plate 27 having a motor control and an exhaust fan 28. Next, the function of the structural material drying device of the asphalt equipment constructed as described above will be described. When heating and drying the regenerated material and the new material at the same time, rotate the rotating drum 3 'to operate the regenerated material input device 9 and the new material input device 1 0' at the same time, and then operate the burner 8 and the deodorizing furnace of the heat funnel 7 above. 1 2 of the burner 1 1. Then, the hot air from the deodorizing furnace 12 is sent to the drum 1 for regenerating structural materials, and the hot air from the burner 8 and the deodorizing furnace 12 is sent to the drum 2 for new structural materials. Edge via cast -10- 482884 V. Description of the invention (9) Entrance 4a and chute 4b, so that the new structure is put into each drum 1,2 through chute 6b. The materials (recycled materials, new materials) put into each of the drums 1 and 2 are heated and dried while being transferred from the upstream side to the downstream side, and are discharged from the outlet 5 a of the heat funnel 5 and the heat funnel respectively. The discharge port 7a of 7 is discharged. The exhaust gas discharged by the heating and drying operation of each structural material is purified by the exhaust fan 2 8 flowing through the dust collecting device 1 3 and released into the atmosphere from the chimney. As described above, the recycled structural member is put into one end side (upstream measurement) of the recycled structural member drum 1, and the scraper 17 covering the inner periphery of the recycled member is lifted up under the recycled structural member drum 1, It is dropped on the upper part, and is sequentially transferred to the other end side (downstream side), and heated and dried by being exposed to hot air from the deodorizing furnace 12. At this time, the squeegee member 19 provided on the downstream side of the squeegee 17 is inclined to push the regeneration structure toward the upstream side, and the downstream of the regeneration member drum 1 faces the regeneration member and moves downstream. The speed becomes slow, and the residence time of the regenerated structure in the regenerated structure drum 1 can be sufficiently ensured. Further, during the inclined blade member 19, since the slit portion 19d is provided in the side portion 19c, the blade member 19 rises in the same direction as the drum 1 for the recycled structure, and the recycled structure is regenerated. The material is gradually returned to the original upstream side with the bottom edge portion 19 c, and the lower part of the drum 1 is formed from the above-mentioned slit 19 d, and the falling film (fall distribution) of the recycled structure becomes uniform. Furthermore, since the ratio (L / D) of the length L to the diameter D of the drum 1 is set in the range of 1 · 5 ~ 2 · 5, and the diameter D of the drum 1 is set to be large, the above-mentioned recycled structure can be dropped. The width of the film is large, so it can be regenerated well. 11- 482884 V. Description of the invention (10) Contact of the component with hot air. Therefore, according to the above-mentioned drum 1 for recycled structural materials, as described above, the ratio (L / D) of the length L of the diameter D of the drum 1 is set to a range of 1.5 to 2.5, which is smaller than that of a conventional person. It is also possible to reliably supply a regenerated member capable of producing a good dryness of an asphalt composite material.同时 At the same time, the new structure put into the upper side of one end of the drum 2 for new structure is heated and dried with the recycled structure based on the above-mentioned recycled structure, and is sequentially transferred to the downstream side along with the rotation of the drum 2 While being heated and dried, the heating and drying effect of the new structure material in the new structure material drum 2 at this time is the same as that in the case of the regenerated structure material drum 1 described above, so the description is omitted. '' As mentioned above, the exhaust gas containing the smoke component is heated and dried to regenerate the structure. It is connected to the air purifying filter 5 b of the heat hopper 5 discharge box 5 c. After removing the smoke component, it is actuated through the exhaust duct 25. The combination of heating and drying of the new structure material and the exhaust gas flowing from the exhaust duct 26 is attracted by the dust collecting device 13 to remove dust. Therefore, in addition to completely removing the smoke or dust in the exhaust gas, the use of a bag filter as the dust collection device 13 also reduces the clogging of the mesh. When the baffle 22 is opened at the above-mentioned position and the blower 21 is operated, the exhaust gas passing through the hollow filter 5b is sent to the combustion chamber of the deodorizing furnace 12 through the air supply duct 20, and the residual smoke is pre-burned there. So ‘be protected from the odor of smoke. The circulation volume of the exhaust gas to the deodorizing furnace 12 is adjusted by adjusting the opening and closing degree of the baffle 22 and the exhaust baffle 2..5 & or adjusting the operation of the blower 2 1-12-482884 V. Description of the invention (11 ) Speed to adjust it. In addition, the amount of hot air generated in the deodorizing furnace 12 for the regenerating drum 1 and the renewing drum 2 is adjusted by adjusting the opening and closing degrees of the shutters 23a and 24a. Alas, as mentioned above, both the revolving structural drum 1 and the new structural drum 2 are used, and the case of heating and drying the regenerated structural material and the new structural material has been explained. However, the exhaust duct 26 can also be closed. The air baffle plate 2 6 a and the branch plate 2 4 a of the divergent duct 2 4 are stopped at the same time, and the new structural material input device 1 is stopped at the same time. The recycled structural material is supplied to the recycled structural material drum 1 to heat and dry the recycled structural material only. . In addition, the exhaust baffle 25a of the exhaust duct 25, the baffles 23a, 24a of each branch duct 23, 24 and the baffle 22 of the air supply duct 20 are closed, and the burner 1 1 of the deodorizing furnace 12 is stopped at the same time. By operating and regenerating the structural material input device 9, since the new structural material is supplied to the new structural material drum 2, only the new structural material can be dried by heating. Next, Fig. 5 shows a component drying device B of an asphalt plant according to a second embodiment of the present invention. The component drying device B in FIG. 5 is the structural material drying device A as in the first embodiment described above, and the rotary drum 3 is not a combination of the drum 1 for regenerating materials and the drum 2 for new materials. , And the two drums 1 and 2 are constituted by other bodies. In addition, the drums (revolving drums) 1a and 2a for regenerating structural materials are respectively driven by electric motors (rotary driving devices) 1 6 a and 1 6 b by The rollers 1 5 c and 15 d which are independently rotated and supported are rotatably supported on the support table 14. The other components are the same as those in the first embodiment described above, and therefore the same components are denoted by the same reference numerals and their descriptions are omitted. -13- 482884 V. Description of the Invention (12) The structural material drying device B according to the second embodiment exhibits the same effect as the structural material drying device A of the first embodiment, and exerts the secondary effect. . That is, the drum for regenerating structural material (first rotating drum) 1 a and the drum for new structural material (second rotating drum) 2 a can be driven independently, so when it is not necessary to use one of the drums, stop them. The movement of the drum can be operated by the other drum 2 running alone, which can save energy. Also, while one drum is used for maintenance inspection, repair, etc., the other drum can continue to operate, so the structural material drying device can be operated efficiently. Furthermore, since the drums are replaced during repair, since the length of each drum train is short, the replacement operation can be easily performed. That is, the structural material drying device B of the second embodiment is the same as that of the structural material drying device A of the first embodiment, and the drum 1a for recycled structural materials and the drum 2a for new structural materials are configured as follows: These axes are arranged on the same line, but it is not necessary to constitute the drums 1 a for regenerating structural materials and the drums 2 a for new structural materials to drive them independently. The axes constituting the two drums 1 a and 2 a may be in the same inclined direction and the same inclined angle, or may be arranged on two different lines. Moreover, the same inclination angle may be arranged as if the inclination directions are opposite to each other, or they may be on different lines. In such cases, the inlets of the structural materials (recycled materials, new materials) are set at the ends of the drums 1 a and 2 a that are inclined to the high position, and the materials are set at the end of the bottom position. The discharge port moves the structural material from the high position side to the low position side. Next, Fig. 6 shows the asphalt equipment according to the third embodiment of the present invention. -14-482884 V. Structure drying device c of the invention description (13). The structural material drying device C in FIG. 6 is a structure in which the regenerative structural material drum (first rotating drum) 1 a and the new structural material drum (second rotating drum) 2 a are supported by the respective supporting tables. For those who install on asphalt equipment. The other components are the same as those of the structural material drying devices A and B of the above-mentioned embodiments. Therefore, the same symbols are attached to the same components and their explanations are omitted. The structural material drying device C according to this embodiment has the same functions and effects as the structural material drying devices A and B of the above-mentioned embodiments, and can appropriately set a drum for regenerating structural materials according to the conditions of the installation place. The arrangement of 1 b and the new construction drum 2 b. According to the structural material drying devices A, B, and C of the first, second, and third embodiments described above, at least the drums for regeneration structural materials (first rotating drums) 1: la, lb and drums for new structural materials One of the wheels (second rotating drum) 2, 2a, 2b, the ratio (L / D) of the length L to the rotating drum diameter D is set to a number smaller than the conventional structure drying device by 1.5 to 2.5. Range, so the full length of the rotating drum 3 of the structural material drying device is shortened, and only its component can make the required area of the structural material drying device small, and the surface area of the drum is also small, reducing the heat radiation from the outer wall surface of the drum. Can achieve energy saving. If a structure drying device is to be installed on an elevated stand, the length of the stand is shortened to reduce its size, and the production cost can be greatly reduced. Next, for example, the diameter of the rotating drum D = 2.1 m, and the length L = The conventional 8m drum for new structural materials (drum volume 27.7m3), with the same drum volume, set the new structural material drum according to the present invention's setting # -15- 482884 V. Description of the invention (14) Rotation The diameter of the drum is D = 2.6 m, and the length is L = 5.2 m 'L / D = 2.0. The length L of the rotating drum is shorter than the conventional one by 2 · διη 〇 Also, the surface area of the conventional rotating drum is 5 2.8 m2, the surface area of the new structural drum according to the present invention is 4 2.5 m2, which is about 19.5% less than the conventional ratio. This reduced surface area component contributes to reducing the heat radiation from the drum wall. According to the actual operation results, the use of the drum for the new structural material according to the present invention has confirmed that it is 5 to 10% higher than the conventional one. Thermal efficiency for energy saving. Fig. 7 compares the structure drying device A of the first embodiment or the structure drying device B of the second embodiment when comparing the installation of the structure drying device when it is installed in an asphalt facility (Fig. 7 (A)) Area S1 'and the structure drying device that supports conventionally known reclaimed structural drums and new structural drums on the support stand, and is installed in the asphalt equipment (Figure 7 (B)) The setting area S2. As can be understood from Fig. 7, the structural material drying device 'according to the first or second embodiment of the present invention is a relatively conventional structural material drying device, which can greatly reduce the installation area (about 40%). (Figure 7) 2y is a drum used for regenerating structural materials for conventional drying and heating devices, 31 is a mixing tower for asphalt equipment, 3 is a storage device for recycled aggregates, and 3 is a drum attached to recycled materials. 2 y combustion chamber. The other symbols are the same as those described in the structural material drying devices A and B of the above embodiments. In addition, inside the rotating drum 3, a reclining squeegee is provided on the upstream side of the reclaimed structure or new member to push back to a certain conveying direction. -16-482884 V. Description of the invention (15) 19, so as mentioned above, The ratio of the length L to the drum diameter D (L / D) is set to be smaller than that of a known person, which fully ensures the residence time in the rotating drum 3 of the recycled or new structure, and can be used in the manufacture of asphalt equipment. Synthetic materials require the required dryness. Next, the conventional new construction material drum (the diameter of the rotating drum D = 2.1m, the length L = 8m, and L / D = 3.8) was actually operated, and the new construction material drum (rotating drum) Drum diameter D = 2.6m, length L = 5.2m, L / D = 2), used to compare the dryness of the structure under the residence time of the structure inside the rotating drum (the residual moisture content of the structure after drying) w 'results for the conventional new construction material drum T = 2 18 seconds, w = 0. 〇2 ~ 0.06%, the new construction material drum according to the present invention, the L / D of the rotating drum It is smaller than the conventional one, but in the residence time of the material, the dryness is confirmed to be inferior to the conventional one. Alas, in the above embodiment, the rotary drum 3 is provided with drums 1, 1 a, 1 b for regenerating structural materials and drums 2, 2 a, 2 b for new structural materials, and is configured to heat and dry the regenerated materials and Both parties of the new structure or one of them, but it is constituted to have only one of the drums for the recycled structure and the drum for the new structure, and only the recycled structure and the new structure are separately heated and dried. Structural material drying devices are also possible. In this case, the installation area of the desired structural material drying device can be made small, and energy saving can be achieved. [Industrial Applicability] As described above, according to the structure drying device of the asphalt equipment of the present invention, the ratio (L / D) of the length L to the diameter D of the rotating drum is set to a range of 1.5 to 2.5, so When the rotating drum is made to have a certain volume, compared with Xi-17-482884 V. Invention Description (16), the length can be shortened and the diameter D 'can be increased, so the upper part of the structure is dropped by the scraper. The width of the film is wide, and the length of the rotating drum is short, and the contact of the structure with the hot air is performed well to obtain the desired dryness. Furthermore, the short length of the rotating drum can reduce the area required for the structure drying device. Therefore, the bitumen equipment can be easily installed without being restricted in its installation location.
