Description

鑄液取湯裝置
本發明是有關於一種鑄液取湯裝置，特別是指一種可調速的鑄液取湯裝置。
一般的給湯是指將熔爐內的鑄液送至鑄模處，以進行鑄造製程。通常給湯分為間接給湯及直接給湯。間接給湯是指以人工方式透過舀湯工具將金屬溶液由坩堝內送至該鑄模處，此種供料方式的缺點為易受人為因素影響而使定位精準差，導致鑄液溢出而易生危險，此外，此種方式由於給湯過程中是將金屬鑄液暴露於空氣中，因此鑄液溫度下降的幅度大，造成控制上之困擾。
直接給湯是指以自動化的鑄液取湯裝置將鑄液由坩堝內取出，再利用輸料管導引至鑄模的料管內。此種給湯方式不需人力，利於自動化且安全度高。然而，一般的鑄液取湯裝置是以馬達帶動螺桿旋轉，以透過螺紋將鑄液向上導引至引流座後，再輸送至鑄造機中。但由於該螺桿頂部是直接接觸空氣，因此長時間使用下會造成金屬殘渣凝結，從而發生阻塞或故障等情事。此外，當製程不同時，便需要使用不同金屬熔成的鑄液，但該鑄液取湯裝置的馬達通常是使用轉速高、扭力小且無法調速的二極馬達，故無法同時適配不同比重的鑄液，泛用性較低。
因此，本發明之目的，即在提供一種避免鑄液接觸空氣且可調速的鑄液取湯裝置。
於是，本發明鑄液取湯裝置，包含一驅動單元、一汲湯單元，及一輸送單元。該驅動單元包括一基架，及一設置於該基架上且可調速的動力源。該汲湯單元包括一由該動力源向下延伸且可被該動力源帶動旋轉的轉軸、一設置於該轉軸末端的扇葉、一具有一出液口及一入液口並容置該扇葉的輸液室，及一連通該輸液室之入液口且形成有複數吸取孔的汲取室。該輸送單元包括複數彼此相互連接並連通該輸液室之出液口的輸送管。
該動力源可受操作而帶動該轉軸及該扇葉旋轉，使該輸液室形成負壓而將鑄液由該汲取室之該等吸取孔吸入該汲取室內，接著通過該入液口後進入該輸液室，最後由該出液口進入該等輸送管中。
本發明之功效在於：鑄液被該汲取室吸入後，便通過該輸液室而直接進入該等輸送管中，故可避免直接接觸外界空氣，降低金屬凝結及阻塞等情事之發生。該動力源可調速，因此可對應不同比重的鑄液，適配性高。
參閱圖1，為本發明鑄液取湯裝置之一實施例，適用於一鑄造機1。該鑄液取湯裝置包含一驅動單元2、一汲湯單元3，及一輸送單元4。該驅動單元2包括一基架21、一設置於該基架21上的動力源22，及複數連接該基架21及該鑄造機1的吊環23。在本實施例中，該動力源22為可調速馬達，較佳輸出功率為2馬力，且最大轉速為1500rpm，特別為六極馬達。該基架21具有複數撐立於地面的支撐柱211、一設置於該等支撐柱211頂端的阻熱板212，及一設置於該阻熱板212上並供該馬達設置的載台213。在本實施例中，該等支撐柱211為不銹鋼條，該阻熱板212為電木板而可保護該動力源22不受高溫損壞。 該等吊環23是連接該載台213，以將該基架21及該動力源22固定於該鑄造機1上。
參閱圖1、圖2及圖3，該汲湯單元3包括一連接於該動力源22底端且穿設該阻熱板212及該載台213並向下延伸的轉軸31、一設置於該轉軸31底端的扇葉32、一圍繞並容置該扇葉32的輸液室33，及一連接於該輸液室33底端的汲取室34。該輸液室33是浸於鑄液內，並包括一圍繞出一橫向開設的出液口330並被該轉軸31沿高度方向穿設的上殼蓋331，及一圍繞出一朝下的入液口332且與該上殼蓋331對合的下殼座333。該上殼蓋331及該下殼座333界定出一容置該扇葉32且連通該出液口330及該入液口332的攪動空間334。該汲取室34包括一圍繞出一朝上的通口341且連接於該下殼座333底面的管殼體342，及複數開設於該殼體上的吸取孔343。該通口341是連接該入液口332，從而使該等吸取孔343連通該攪動空間334。需要特別說明的是，該等吸取孔343的面積之總合大於或等於該出液口330的面積，且前述兩者的差值小於10%。
該輸送單元4包括一連接該基架21的固定支架41、複數彼此相互連接且連通該輸液室33之出液口330的輸送管42、複數分別套設於該等輸送管42上的保溫套管43、複數分別附著於該等輸送管42內壁面的電鍍層44、複數分別鋪設於該等輸送管42及該等保溫套管43之間的保溫棉45，及一設置於位於末端的輸送管42上的握把46。該固定支架41是用於固定連接該出液口330的輸送管42。該等輸送管42頭尾相連且可相對於彼此旋動，自由度高。該等保溫套管43的材質為不銹鋼，可用於保持通過該等輸送管42的鑄液之溫度。該等電鍍層44的成分為鎳與磷之混合，或鐵氟龍，其有著疏水性高之特性，因此可防止鑄液於該等輸送管42中堵塞或黏附。
設置時，該輸液室33及該汲取室34是浸於該鑄造機1的熔爐內(圖未示)，以位於鑄液的液面下方，因此鑄液會經由該等吸取孔343、該通口341及該入液口332充滿該攪拌空間。操作時，該動力源22可帶動該轉軸31繞一通過自身中心的直立軸線旋轉，從而使該扇葉32於該攪拌空間內旋轉，該扇葉32轉動時會將該攪拌空間內的鑄液撥動至該出液口330，並由該出液口330送入該等輸送管42中，由於該等吸取孔343的面積之總合大於或等於該出液口330的面積，因此會使該攪拌空間內形成負壓，從而持續地將鑄液由該等吸取孔343吸入，而配合該動力源22低轉速及高扭力之特性，便可穩定地將鑄液持續送至該出液口330，並在通過該等輸送管42後輸出至該鑄模處。該握把46可供操作人員提取，以移動該等輸送管42。該動力源22為可調速的六極馬達，因此可根據銅合金、鋅合金、鋁合金或銅鋅合金等不同鑄液的不同比重來調整轉速，以達到較佳的輸送效果。
需要特別說明的是，當該扇葉32旋轉一圈時，所送入的鑄液恰可將該出液口330填滿而無空隙，以避免空氣被打入該等輸送管42內。
綜上所述，透過該汲湯單元3及該動力源22可將鑄液不與外界空氣直接接觸地送至該等輸送管42中，且該動力源22可調速而可配合多種不同比重的鑄液，泛用性高，故確實能達成本發明之目的。
惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。
