Description
本發明係關於一種分離金屬介在物之裝置及方法,詳言之,係關於一種分離浮渣中金屬介在物及氧化物與鋅金屬之裝置及方法。The present invention relates to an apparatus and method for separating a metal intervening material, and more particularly to an apparatus and method for separating metal intercalates and oxides and zinc metal in scum.
習知熱浸鍍鋅製程所產生之浮渣,依其所含介在物不同,大致上可分為兩種:一種係以氧化物為主,另一種係以介金屬化合物(金屬介在物)為主。但不論是哪一類浮渣,其中之鋅金屬含量皆相當可觀。The scum produced by the hot dip galvanizing process can be roughly divided into two types according to the different materials contained therein: one is mainly oxide and the other is a metal intermetallic compound (metal intervening). the Lord. But no matter which type of scum, the zinc metal content is quite considerable.
美國專利第2,134,605號揭示將浮渣裝入一旋轉鐵桶中,再加熱鐵桶使浮渣熔化,並利用旋轉促進鋅金屬液與浮渣分離。美國專利第3,198,505號揭示將浮渣置於一有滲透性之基板上,再將其加熱使鋅金屬液流出。美國專利第4,057,232號揭示之方法則係不加熱,而係利用一多孔勺子盛滿浮渣,再由該多孔勺子上方之壓板擠壓浮渣,使鋅金屬液透過該多孔勺子之孔洞流出。美國專利第4,003,559號揭示之方法也是使用擠壓浮渣方式,利用電風扇葉片般的旋轉刮板擠壓浮渣,讓浮渣中之鋅金屬液流出。然而,上述該等習知鋅金屬回收方法效率不高,並且只適合回收以氧化物為主之浮渣,對於以介金屬化合物為主的浮渣之分離效果並不好,因此回收鋅金屬液總是有雜質含量偏高的問題。U.S. Patent No. 2,134,605 discloses the application of scum to a rotating iron drum, the heating of the iron drum to melt the scum, and the use of rotation to promote separation of the zinc metal liquid from the scum. U.S. Patent No. 3,198,505 discloses the application of scum to a permeable substrate which is then heated to allow the molten metal to flow out. The method disclosed in U.S. Patent No. 4,057,232, which is not heated, utilizes a porous spoon to fill the scum, and the scum is pressed from the platen above the porous spoon to allow the zinc metal to flow out through the pores of the porous spoon. The method disclosed in U.S. Patent No. 4,003,559 also uses an extrusion scum method in which a scum is extruded by an electric fan blade-like rotary squeegee to allow zinc metal liquid in the scum to flow out. However, the above-mentioned conventional zinc metal recovery methods are not efficient, and are only suitable for recovering oxide-based scum, and the separation effect of the scum mainly composed of the metal-containing compound is not good, so the zinc metal liquid is recovered. There is always the problem of high impurity levels.
關於含介金屬化合物為主的浮渣之回收,美國專利第4,075,008號揭示利用介在物會使浮渣流動性劣化的特性,在680℃以下加熱浮渣,保持浮渣本身的形狀及強度,使鋅金屬液由浮渣中流出,但回收率不高(低於50%),回收鋅金屬液純度最高也僅能達到Fe濃度為0.02%,且Fe濃度隨著加熱溫度的上昇而提高,在566℃時Fe濃度已達0.06%,無法達到原料鋅錠之要求水準。美國專利第4,269,398號所揭示之方法類似美國專利第4,075,008號,其得到的結果也相當類似,鋅金屬液之回收率及純度不高。此外,亦有以蒸餾法收集鋅蒸氣再冷凝的方法,但缺點是製程過於複雜。Regarding the recovery of the scum containing the metal-containing compound, U.S. Patent No. 4,075,008 discloses the use of a medium to deteriorate the fluidity of the scum, and the scum is heated at 680 ° C or lower to maintain the shape and strength of the scum itself. The zinc metal liquid flows out from the scum, but the recovery rate is not high (less than 50%). The purity of the recovered zinc metal liquid can only reach the Fe concentration of 0.02%, and the Fe concentration increases with the increase of the heating temperature. At 566 ° C, the Fe concentration has reached 0.06%, which cannot meet the required level of the raw material zinc ingot. The method disclosed in U.S. Patent No. 4,269,398 is similar to U.S. Patent No. 4,075,008, the results of which are also quite similar, and the recovery and purity of the zinc metal liquid are not high. In addition, there is also a method of collecting zinc vapor by distillation to recondense, but the disadvantage is that the process is too complicated.
因此,有必要提供一創新且富有進步性之分離浮渣中金屬介在物及氧化物與鋅金屬之裝置及其分離方法,以解決上述問題。Therefore, it is necessary to provide an innovative and progressive device for separating metal intercalation and oxide and zinc metal in scum and a separation method thereof to solve the above problems.
本發明提供一種分離浮渣中金屬介在物及氧化物與鋅金屬之裝置,該浮渣具有一比例之鋅金屬含量,該浮渣加熱熔化後原浮渣中之金屬介在物、氧化物及熔化之鋅金屬液上方部分形成一金屬介在物-氧化物-鋅金屬液混合層,該分離裝置包括:一容納單元及一擾動單元。該容納單元加熱熔化該浮渣以及容設該鋅金屬液及該金屬介在物-氧化物-鋅金屬液混合層。該擾動單元用以置入該金屬介在物-氧化物-鋅金屬液混合層表面下一設定深度,以一設定擾動速度擾動該金屬介在物-氧化物-鋅金屬液混合層。The invention provides a device for separating metal intercalates and oxides and zinc metal in scum, the scum having a proportion of zinc metal content, the scum heating and melting, the metal interdiction, oxide and melting in the original scum The upper part of the zinc metal liquid forms a metal intervening-oxide-zinc metal liquid mixed layer, and the separating device comprises: a receiving unit and a disturbance unit. The accommodating unit heats and melts the scum and accommodates the zinc metal liquid and the metal intervening material-oxide-zinc metal liquid mixed layer. The disturbance unit is configured to place a depth of the metal on the surface of the material-oxide-zinc metal mixed layer to disturb the metal-intermediate-oxide-zinc metal mixed layer at a set disturbance speed.
本發明另提供一種分離浮渣中金屬介在物及氧化物與鋅金屬之方法,該浮渣具有一比例之鋅金屬含量,該方法包括以下步驟:(a)加熱熔化該浮渣,該浮渣加熱熔化後該金屬介在物、該氧化物及熔化之鋅金屬液上方部分形成一金屬介在物-氧化物-鋅金屬液混合層;(b)於該金屬介在物-氧化物-鋅金屬液混合層表面下一設定深度,以一設定擾動速度擾動該金屬介在物-氧化物-鋅金屬液混合層;(c)靜置該鋅金屬液及該金屬介在物-氧化物-鋅金屬液混合層;及(d)移除該金屬介在物及該氧化物。The invention further provides a method for separating metal intercalation and oxide and zinc metal in scum, the scum having a proportion of zinc metal content, the method comprising the steps of: (a) heating and melting the scum, the scum After heating and melting, the metal intervening material, the oxide and the molten zinc metal liquid partially form a metal intervening oxide-zinc metal liquid mixed layer; (b) the metal intervening-oxide-zinc metal liquid mixing a set depth of the layer surface, disturbing the metal-intermediate-oxide-zinc metal liquid mixed layer at a set disturbance speed; (c) standing the zinc metal liquid and the metal intervening-oxide-zinc metal liquid mixed layer And (d) removing the metal intervening material and the oxide.
本發明分離浮渣中金屬介在物及氧化物與鋅金屬之裝置及方法利用旋轉或振動方式,擾動加熱熔化浮渣後之該金屬介在物-氧化物-鋅金屬液混合層,藉此可大幅提昇該金屬介在物及該氧化物與該鋅金屬液之分離效果,其中,鋅金屬液之回收率可提高至82%,且該鋅金屬液中之Fe含量則可降至0.003%。因此,本發明分離浮渣中金屬介在物及氧化物與鋅金屬之裝置及方法確實可有效回收得非常純淨之鋅金屬液。The apparatus and method for separating metal intercalation and oxide and zinc metal in the scum of the present invention utilizes a rotating or vibrating manner to disturb the metal-intermediate-oxide-zinc metal liquid mixed layer after the heating and melting of the scum, thereby greatly increasing The separation effect of the metal intervening material and the oxide and the zinc metal liquid is improved, wherein the recovery rate of the zinc metal liquid can be increased to 82%, and the Fe content in the zinc metal liquid can be reduced to 0.003%. Therefore, the apparatus and method for separating metal intercalation and oxide and zinc metal in the scum of the present invention can effectively recover a very pure zinc metal liquid.
在熱浸鍍鋅(Zn)線(例如:連續式熱浸鍍鋅線)生產過程中,鋅槽中之雜質Fe會與Al反應形成比重較輕的介金屬化合物(金屬介在物),其會漂浮於鋅槽表面而形成浮渣。該浮渣撈出後尚含90%以上之Zn,因此需將金屬介在物與鋅金屬液分離再回收清淨之鋅金屬液。然而浮渣中常混有由大量氧化物形成之氧化膜,阻撓金屬介在物上浮,導致金屬介在物與鋅金屬液之分離效果不佳。In the production process of hot dip galvanized (Zn) wire (for example, continuous hot dip galvanizing line), the impurity Fe in the zinc bath reacts with Al to form a relatively small specific intermetallic compound (metal intervening), which will Floating on the surface of the zinc tank to form scum. The scum still contains more than 90% of Zn after being removed, so it is necessary to separate the metal intervening material from the zinc metal liquid and recover the cleaned zinc metal liquid. However, the scum is often mixed with an oxide film formed by a large amount of oxides, which hinders the metal from floating on the material, resulting in poor separation of the metal intervening material and the zinc metal liquid.
圖1顯示本發明分離浮渣中金屬介在物及氧化物與鋅金屬之裝置示意圖。該浮渣具有一比例之鋅金屬含量,在該浮渣加熱熔化後,金屬介在物(例如:Fe2 Al5 )、氧化物及熔化之鋅金屬液11上方部分形成一金屬介在物-氧化物-鋅金屬液混合層10。其中,圖1中之顆粒部分,在此係示意金屬介在物及氧化物混雜於該金屬介在物-氧化物-鋅金屬液混合層10中之情況。BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing the apparatus for separating metal intercalates and oxides and zinc metal in the scum according to the present invention. The scum has a proportion of zinc metal content, and after the scum is heated and melted, a metal intervening substance is formed on the metal medium (for example, Fe 2 Al 5 ), the oxide, and the molten zinc metal liquid 11 . - Zinc metal liquid mixed layer 10. Here, the particle portion in Fig. 1 is a case where the metal intervening substance and the oxide are mixed in the metal intervening-oxide-zinc metal liquid mixed layer 10.
該分離浮渣中金屬介在物及氧化物與鋅金屬之裝置2包括:一容納單元21、一擾動單元22、一控制器23及一擋渣元件24。該容納單元21加熱熔化該浮渣,以及容設該鋅金屬液11及該金屬介在物-氧化物-鋅金屬液混合層10。在本實施例中,該容納單元21包括一加熱器211及一澆嘴212,其中,該加熱器211較佳係環設於該容納單元21之周圍,用以加熱熔化該浮渣,該澆嘴212係位於該容納單元21之頂緣周邊,處理後之該鋅金屬液11在後續之澆鑄製程中,即係由該澆嘴212流出澆鑄於一鑄模中,以製作成原料鋅錠。The apparatus 2 for separating metal intercalation and oxide and zinc metal in the scum includes a receiving unit 21, a disturbance unit 22, a controller 23 and a slag blocking member 24. The accommodating unit 21 heats and melts the dross, and accommodates the zinc metal liquid 11 and the metal intervening material-oxide-zinc metal liquid mixed layer 10. In this embodiment, the accommodating unit 21 includes a heater 211 and a spout 212. The heater 211 is preferably disposed around the accommodating unit 21 for heating and melting the scum. The nozzle 212 is located around the top edge of the accommodating unit 21, and the treated zinc metal liquid 11 is discharged from the pouring nozzle 212 into a mold in a subsequent casting process to form a raw material zinc ingot.
該擾動單元22用以置入該金屬介在物-氧化物-鋅金屬液混合層10表面下一設定深度h,以一設定擾動速度擾動該金屬介在物-氧化物-鋅金屬液混合層10。配合參考圖1及圖2,該擾動單元22包括一基部221及至少一桿部222,在本實施例中,該擾動單元22包括複數個桿部222,且該等桿部222實質上偏心地連接該基部221。其中,該等桿部222用以置入該金屬介在物-氧化物-鋅金屬液混合層10表面下之該設定深度h。較佳地,該設定深度h係大於該金屬介在物-氧化物-鋅金屬液混合層10之厚度,在本實施例中,該設定深度h係為該金屬介在物-氧化物-鋅金屬液混合層10之表面下約二分之一深度。其中,若該擾動單元22係為一旋轉裝置(例如:旋轉馬達裝置),則該基部221係移動至每一區域之該金屬介在物-氧化物-鋅金屬液混合層10之上方相對位置,且每一桿部222繞其中心軸旋轉,以旋轉擾動該金屬介在物-氧化物-鋅金屬液混合層10。要注意的是,該擾動單元22亦可為一振動裝置,例如:一超音波振動器或振動馬達。The disturbance unit 22 is configured to place the metal on the surface of the material-oxide-zinc metal mixed layer 10 at a set depth h to disturb the metal-intermediate-oxide-zinc metal mixed layer 10 at a set disturbance speed. Referring to FIG. 1 and FIG. 2, the disturbance unit 22 includes a base portion 221 and at least one rod portion 222. In the present embodiment, the disturbance unit 22 includes a plurality of rod portions 222, and the rod portions 222 are substantially eccentrically The base 221 is connected. The rod portions 222 are used to set the set depth h of the metal under the surface of the material-oxide-zinc metal mixed layer 10. Preferably, the set depth h is greater than the thickness of the metal-intermediate-oxide-zinc metal mixed layer 10. In the present embodiment, the set depth h is the metal-intermediate-oxide-zinc metal solution. The surface of the mixed layer 10 is about one-half the depth below the surface. Wherein, if the disturbance unit 22 is a rotating device (for example, a rotary motor device), the base portion 221 is moved to a relative position of the metal intervening material-oxide-zinc metal liquid mixed layer 10 in each region. And each of the rod portions 222 is rotated about its central axis to rotate the metal intervening material-oxide-zinc metal liquid mixed layer 10. It should be noted that the disturbance unit 22 can also be a vibration device such as an ultrasonic vibrator or a vibration motor.
該控制器23連接該擾動單元22,用以控制該擾動單元22之設定擾動速度及置入該金屬介在物-氧化物-鋅金屬液混合層10表面下之該設定深度h。該擋渣元件24設置於該澆嘴212之上方相對位置,該擋渣元件24與該澆嘴212形成一澆鑄通道25。其中,擾動該鋅金屬液11及該金屬介在物-氧化物-鋅金屬液混合層10後,經靜置使得金屬介在物及氧化物上浮,降低該金屬介在物-氧化物-鋅金屬液混合層10之厚度,接著再移除(例如:耙除方式)該金屬介在物及該氧化物。在移除該金屬介在物及該氧化物後,該澆鑄通道25允許純淨之該鋅金屬液11由該容納單元21流出,而該擋渣元件24則進一步止擋該鋅金屬液11之液面上可能未完全移除之金屬介在物或氧化物,以避免其流入鑄模中。The controller 23 is connected to the disturbance unit 22 for controlling the set disturbance speed of the disturbance unit 22 and the set depth h of the metal interposed under the surface of the material-oxide-zinc metal mixed layer 10. The slag blocking element 24 is disposed at an opposite position above the spout 212, and the slag blocking member 24 forms a casting passage 25 with the spout 212. Wherein, after disturbing the zinc metal liquid 11 and the metal intervening in the material-oxide-zinc metal liquid mixed layer 10, the metal medium and the oxide are floated after being allowed to stand, thereby reducing the metal intervening-oxide-zinc metal liquid mixture. The thickness of layer 10 is then removed (e.g., by means of the removal) of the metal intervening material and the oxide. After the removal of the metal intervening material and the oxide, the casting channel 25 allows the pure zinc metal liquid 11 to flow out of the receiving unit 21, and the slag blocking member 24 further stops the liquid level of the zinc metal liquid 11. A metal intervening or oxide may not be completely removed to prevent it from flowing into the mold.
圖3顯示本發明分離浮渣中金屬介在物及氧化物與鋅金屬之方法流程圖。配合參考圖1至圖3,參考步驟S31,首先,提供一容納單元21,該容納單元21用以加熱熔化該浮渣,以及容設該鋅金屬液11及該金屬介在物-氧化物-鋅金屬液混合層10。較佳地,在步驟S31中,該容納單元21係以540℃至850℃加熱熔化該浮渣。Figure 3 is a flow chart showing the method of separating metal intercalates and oxides from zinc metal in the scum according to the present invention. Referring to FIG. 1 to FIG. 3, referring to step S31, first, a receiving unit 21 is provided for heating and melting the dross, and the zinc metal liquid 11 and the metal intervening-oxide-zinc are accommodated. The metal liquid mixed layer 10. Preferably, in step S31, the housing unit 21 heats and melts the dross at 540 ° C to 850 ° C.
參考步驟S32,添加一除渣劑(flux)至熔化之該鋅金屬液11及該金屬介在物-氧化物-鋅金屬液混合層10中。其中,由於氧化物在熱浸鍍鋅槽之液面形成,其呈現膜狀,並會在撈取後纏繞包圍金屬介在物及鋅金屬,使得金屬介在物在浮渣重熔後仍難與鋅金屬液分離,為解開氧化物對金屬介在物及鋅金屬之纏繞,故在浮渣熔化後添加除渣劑,以初步分離氧化物、金屬介在物及鋅金屬。Referring to step S32, a slag is added to the molten zinc metal liquid 11 and the metal intervening-oxide-zinc metal liquid mixed layer 10. Among them, since the oxide is formed on the liquid surface of the hot dip galvanizing bath, it is in the form of a film, and will wrap around the metal intervening material and the zinc metal after being taken up, so that the metal intercalation is still difficult to be combined with the zinc metal after the reflow of the dross. The liquid separation is to unwind the entanglement of the metal intercalation and the zinc metal. Therefore, after the scum is melted, a slag removing agent is added to initially separate the oxide, the metal intervening substance and the zinc metal.
參考步驟S33,將一擾動單元22置入該金屬介在物-氧化物-鋅金屬液混合層10表面下一設定深度h,以一設定擾動速度擾動該金屬介在物-氧化物-鋅金屬液混合層10。較佳地,在步驟S33中,該設定深度h係為該金屬介在物-氧化物-鋅金屬液混合層10之表面下約二分之一深度,擾動時間係大於1分鐘。Referring to step S33, a disturbance unit 22 is placed in the metal-on-oxide-zinc metal-mixed layer 10 surface to set a depth h, and the metal-intermediate-oxide-zinc metal mixture is disturbed at a set disturbance speed. Layer 10. Preferably, in step S33, the set depth h is about one-half depth below the surface of the metal-oxide-zinc metal mixed layer 10, and the disturbance time is greater than 1 minute.
在本實施例中,在步驟S33中該擾動單元22係以旋轉擾動方式擾動該金屬介在物-氧化物-鋅金屬液混合層10,在其他應用中,該擾動單元22亦可以振動擾動方式擾動該金屬介在物-氧化物-鋅金屬液混合層10。其中,該擾動單元22較佳係移動地擾動每一區域之該金屬介在物-氧化物-鋅金屬液混合層10。In this embodiment, the disturbance unit 22 disturbs the metal-intermediate-oxide-zinc metal mixed layer 10 in a rotating disturbance manner in step S33. In other applications, the disturbance unit 22 can also be disturbed by vibration disturbance. The metal is interposed in the material-oxide-zinc metal liquid mixed layer 10. Wherein, the disturbance unit 22 preferably movably disturbs the metal-intermediate-oxide-zinc metal mixed layer 10 of each region.
其中,雖然添加除渣劑及利用溫度效應可提高氧化物、金屬介在物及鋅金屬液之分離效果,然而,由於分離效果與熔渣之黏滯係數關係密切,較下層之金屬介在物在上浮過程中,同時也使該金屬介在物-氧化物-鋅金屬液混合層10中之金屬介在物之密度愈來愈高,黏滯係數也隨之增加,當金屬介在物之密度高到某一程度後,金屬介在物即無法上浮,此時則可升高溫度,藉以提升除渣劑去除氧化物效果及降低黏滯係數,使金屬介在物能進一步上浮。Among them, although the addition of the slag removing agent and the use of the temperature effect can improve the separation effect of the oxide, the metal intervening substance and the zinc metal liquid, however, since the separation effect is closely related to the viscous coefficient of the slag, the metal layer of the lower layer is above the floating object. In the process, the density of the metal intervening material in the material-oxide-zinc metal mixed layer 10 is also increased, and the viscosity coefficient is also increased. When the density of the metal intervening substance is high to some After the degree, the metal can not float up. At this time, the temperature can be raised, thereby improving the effect of removing the oxide by the slag removing agent and lowering the viscosity coefficient, so that the metal can further float up.
另外,為進一步提升分離效果,本發明更利用該擾動單元22之該等桿部222置入該金屬介在物-氧化物-鋅金屬液混合層10之表面下之一設定深度h,以高速旋轉或振動之擾動方式擾動該金屬介在物-氧化物-鋅金屬液混合層10,將浮渣中由大量氧化物形成之氧化膜打碎,以利於氧化物及金屬介在物能順利上浮。In addition, in order to further improve the separation effect, the present invention further utilizes the rod portions 222 of the disturbance unit 22 to be placed under the surface of the metal-oxide-zinc metal liquid mixed layer 10 to set a depth h to rotate at a high speed. Or the vibration disturbing method disturbs the metal-intermediate-oxide-zinc metal mixed layer 10, and breaks the oxide film formed by a large amount of oxides in the dross, so as to facilitate the smooth floating of the oxide and the metal.
參考步驟S34,靜置擾動後之該鋅金屬液11及該金屬介在物-氧化物-鋅金屬液混合層10。較佳地,在步驟S34中之靜置時間係大於5分鐘。利用比重差異,令該金屬介在物上浮以與該鋅金屬液11分離。同樣地,當該金屬介在物之密度高到某一程度後,可升高溫度以提升除渣劑去除氧化物效果及降低黏滯係數,並且利用該擾動單元22之該等桿部222將氧化物形成之氧化膜打碎,使該金屬介在物能進一步上浮。Referring to step S34, the zinc metal liquid 11 after the disturbance is left and the metal is interposed in the material-oxide-zinc metal liquid mixed layer 10. Preferably, the rest time in step S34 is greater than 5 minutes. The difference in specific gravity causes the metal to float on the object to separate from the zinc metal liquid 11. Similarly, when the density of the metal intervening material is high to some extent, the temperature can be raised to enhance the effect of removing the oxide by the descum fluxing agent and lower the viscosity coefficient, and the rod portions 222 of the perturbation unit 22 will be oxidized. The oxide film formed by the object is broken, so that the metal can further float upward.
參考步驟S35,移除該金屬介在物及該氧化物。在本實施例中,其係以耙除方式移除該金屬介在物及該氧化物,以避免下層純淨之該鋅金屬液11被未耙除乾淨之金屬介在物及氧化物污染。Referring to step S35, the metal interposer and the oxide are removed. In this embodiment, the metal intervening material and the oxide are removed in a rubbing manner to prevent the underlying pure zinc metal liquid 11 from being contaminated by the metal and oxide which are not removed.
參考步驟S36,進行一擋渣澆鑄之步驟。較佳地,在移除該金屬介在物及該氧化物後,該擋渣元件24與該澆嘴212形成之澆鑄通道25允許純淨之該鋅金屬液11由該容納單元21流出,而該擋渣元件24則進一步止擋該鋅金屬液11之液面上可能未完全移除之金屬介在物或氧化物,以避免其流入鑄模中。Referring to step S36, a step of slag casting is performed. Preferably, after the metal interposer and the oxide are removed, the casting channel 25 formed by the slag blocking member 24 and the spout 212 allows the pure zinc metal liquid 11 to flow out from the receiving unit 21, and the block The slag element 24 further stops the metal intervening or oxide that may not be completely removed from the surface of the zinc metal liquid 11 to prevent it from flowing into the mold.
本發明分離浮渣中金屬介在物及氧化物與鋅金屬之裝置及方法利用旋轉或振動方式,擾動加熱熔化浮渣後之該金屬介在物-氧化物-鋅金屬液混合層10,藉此可大幅提昇該金屬介在物及氧化物與該鋅金屬液11之分離效果,其中,鋅金屬液之回收率可提高至82%,且該鋅金屬液11中之Fe含量則可降至0.003%。因此,本發明分離浮渣中金屬介在物及氧化物與鋅金屬之裝置及方法確實可有效回收得非常純淨之鋅金屬液。The apparatus and method for separating metal intercalation and oxide and zinc metal in the scum according to the present invention utilizes a rotating or vibrating manner to disturb the metal-intermediate-oxide-zinc metal mixed layer 10 after the heating and melting of the scum. The separation effect of the metal intervening substance and the oxide and the zinc metal liquid 11 is greatly improved, wherein the recovery rate of the zinc metal liquid can be increased to 82%, and the Fe content in the zinc metal liquid 11 can be reduced to 0.003%. Therefore, the apparatus and method for separating metal intercalation and oxide and zinc metal in the scum of the present invention can effectively recover a very pure zinc metal liquid.
