Description of the Invention: The present invention relates to a device and a method for separating a metal intervening material, and more particularly to a device for separating a metal intercalate and an oxide and a metal in a dross. method. [Prior Art] The scum produced by the conventional hot dip plating process can be roughly divided into two types depending on the medium contained therein: one is mainly oxide and the other is a metal intermetallic compound (metal). In the matter). But no matter what kind of floating, the zinc metal content is quite considerable. U.S. Patent No. 2,134,605 discloses the application of scum into a rotating iron drum, heating the iron drum to melt the scum, and utilizing the rotation to promote separation of the molten metal 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, No. 57,232, is not heated, but is filled with a scum using a porous spoon, and the scum is squeezed from a press plate above the porous spoon to allow the molten zinc liquid to flow through the pores of the porous spoon. . The method disclosed in U.S. Patent No. 4, No. 3,559 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 metal recovery methods are not efficient, and are only suitable for recovering scum which is mainly composed of oxides, and the separation effect of the scum mainly composed of a mesometallic compound is not good, so the metal liquid is recovered. There is always the problem of high impurity levels. Regarding the recovery of scum mainly containing a metal-containing compound, U.S. Patent No. 136683.doc 201030152 4, 〇75, the surface number reveals that the property may deteriorate the floating (four) dynamic property, and floats in the region below 6 ah, keeping The shape and strength of the floating slab itself make the zinc metal liquid flow out of the consumption, but the recovery rate is not high (below the view), and the purity of the recovered metal liquid can only reach the concentration of 〇〇2%, and the concentration The heating temperature rises and rises at 566. (: The concentration has reached 0.06. / ❶ 'can not reach the required level of raw material reels. The method disclosed in U.S. Patent No. 4'269'398 is similar to U.S. Patent No. 4, 〇75, _, and the results obtained thereof It is also quite similar, the recovery rate and purity of zinc metal liquid is not high. In addition, there is also a method of collecting steam and recondensing by distillation, but the disadvantage is that the process is too complicated. Therefore, it is necessary to provide an innovative and progressive separation. The present invention provides a device for separating metal intervening substances and oxides and zinc metal in scum. The slag has a proportion of zinc metal content, and after the scum is heated and melted, the metal in the original scum forms a metal intervening-oxide-zinc metal mixed layer above the material, the oxide and the molten zinc metal liquid. The separating device comprises: a receiving unit and a disturbing unit. The receiving unit heats and melts the dross and accommodates the metal liquid and the metal intervening-oxide-zinc metal liquid mixture The disturbing unit is configured to place a depth of the metal-on-oxide-zinc metal mixed layer surface to disturb the metal-intermediate-oxide-zinc metal liquid mixed layer at a set disturbance speed. There is further provided a method of separating a metal intermediate and a metal oxide and a metal having a ratio of zinc metal content, the method comprising the steps of: (a) heating and melting the scum, After the scum is heated and melted, the metal intervening material, the oxide and the molten zinc metal liquid partially form a metal intervening-oxide-zinc metal liquid mixed layer; and the metal intervening material _ oxide-zinc metal liquid mixed layer Setting a depth on the surface, disturbing the metal-intermediate-oxide-zinc metal liquid mixed layer at a set disturbance speed; (staging the zinc metal liquid and the metal-intermediate-oxide-zinc metal liquid mixed layer; and (d) removing the metal intervening material and the oxide. The apparatus and method for separating metal intervening substances and oxides and metal in the scum according to the present invention utilize a rotating or vibrating method to disturb the heating and melting After the clearing, the metal is interposed in the mixed layer of the material-oxide-zinc metal solution, thereby greatly improving the separation effect of the metal intervening substance and the oxide and the zinc metal liquid, wherein the recovery rate of the zinc metal liquid can be improved. Up 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 very pure zinc. Metal liquid. [Embodiment] In the production process of hot dip (Zn) wire (for example, continuous hot dip galvanizing line), the impurity Fe in the zinc bath reacts with A1 to form a lighter weight intermetallic compound ( Metal interdiction), which floats on the surface of the groove to form scum. The scum still contains more than 90 〇/〇 of Zn, so it is necessary to separate the metal intervening material from the zinc metal liquid and recover the clean 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 intercalation material from the zinc metal liquid. 136683.doc 201030152 Figure 1 shows a schematic view of a device for separating metal intercalates and oxides from zinc metal in the scum of the present invention. The dross has a proportion of zinc metal content. After the dross is heated and melted, a metal intervening material (eg, Fe2Al5), an oxide, and a molten zinc metal liquid 11 form a metal intervening_oxide_zinc metal. Liquid mixed layer 10. Here, the particle portion in Fig. 1 indicates that the metal intervening substance and the oxide are mixed in the metal intercalation-oxide-zinc metal mixed layer 10. The apparatus 2 for interposing metal intercalates and oxides and zinc metal in the scum includes a housing unit 21, a disturbance unit 22, a controller 23 and a slag blocking member 24. The accommodating unit 21 heats and melts the scum, and accommodates the ruthenium liquid 11 and the metal intervening-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 dross. The nozzle 212 is located at the periphery of 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 prepare a raw material. The disturbance unit 22 is configured to place the metal at the set depth h of the surface of the metal-oxide-metal mixed layer 10 to perturb the metal-intermediate-oxide-zinc metal mixed layer 1 at a set disturbance speed. Referring to Figures 1 and 2, the perturbation unit 22 includes a base 221 and at least one stem 222. In the present embodiment, the perturbation unit 22 includes a plurality of stems 222, and the stems 222 are substantially eccentrically The base 221 is connected. Wherein, the rod portions 222 are disposed at the set depth of the metal-on-oxide-zinc metal-liquid mixed layer 1 136 683.doc • 6 - 201030152, preferably, the set depth h is greater than the The thickness of the metal-intermediate-oxide-zinc metal mixed layer 10, in the present embodiment, the set depth h is about one-half of the metal interposed under the surface of the material-oxide-zinc metal mixed layer 10. depth. Wherein, if the disturbance unit 22 is a rotating device (for example, a rotary motor device), the base 221 is moved to a relative position of the metal-intermediate-oxide-zinc metal mixed layer 1〇 of 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. It is to be noted that the disturbance unit 22 can also be a vibration device such as an ultrasonic vibrator or a vibration motor. The controller 23 is coupled 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 material-oxide-zinc metal mixed layer 10. The slag blocking member 24 is disposed at a position above the nozzle 212. The slag blocking member 24 forms a washing passage 25 with the nip nozzle 212. Wherein, after disturbing the zinc metal liquid 11 and the metal intervening in the material-oxide-metal liquid mixed layer 10, the metal medium and the oxide are floated after being allowed to stand, thereby reducing the metal-intermediate-oxide-zinc metal liquid mixture. The thickness of layer 10 is then removed (eg, by way of removal) of the metal intervening material and the oxide. After removing the metal intervening material and the oxide, the casting channel 25 allows the pure zinc metal liquid 11 to flow out of the accommodating unit 21, and the slag-removing element 24 further stops the liquid level of the zinc metal liquid u. A metal intervening or oxide may not be completely removed to prevent it from flowing into the mold. Fig. 3 is a flow chart showing the method of separating metal intercalates and oxides and retrieving metals from the scum according to the present invention. With reference to FIG. 1 to FIG. 3, referring to step 831, the first 136683.doc 201030152 first, a receiving unit 21 is provided for heating and melting the dross, and the zinc metal liquid 11 and the metal intervening material are accommodated.

Wherein, 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 the inclusion, so that the metal intercalation is still difficult after the scum is re-dissolved. The zinc metal liquid is separated to decompose the oxide to the metal intervening material 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. Referring to step S33, a disturbance unit 22 is placed on the surface of the metal-on-oxide-metal mixed layer 10 to set a depth h, and the metal-intermediate-oxide-zinc metal mixture is disturbed at a set disturbance speed. Layer 1〇. 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 one minute. In this embodiment, the disturbance unit 22 disturbs the metal-intermediate-oxide-zinc metal mixed layer 1〇 in a rotating disturbance manner in step S33, and the disturbance unit 22 can also vibrate in other applications. The mode disturbs the metal intervening material-oxide-zinc metal liquid mixed layer, and the disturbance unit 22 preferably movably disturbs the metal intervening oxide layer 10 of each region. Among them, although the addition of the slag remover and the use of temperature effects can improve the separation effect of the oxide, 136683.doc 201030152 metal intercalation and zinc metal liquid, however, because the separation effect is closely related to the viscous coefficient of the slag, the lower layer of metal During the floating process, the metal is also interposed in the material-oxide-metal mixed layer, and the density of the metal is increased. The viscosity coefficient also increases. When the density is high to a certain extent, the metal can not float upwards. At this time, the temperature can be raised, so as to improve the effect of removing the oxide by the slag removing agent and lowering the viscous coefficient, the metal can be further floated. 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-metal mixed layer 10 to set a depth h to rotate at a high speed. Or the vibration disturbing method disturbs the metal in the material-oxide-zinc metal mixed layer, and ruptures the oxide film formed by a large amount of oxides in the scum, so as to facilitate the smooth floating of the oxide and the metal. Referring to step S34, the zinc metal liquid u and the metal-intermediate-oxide-zinc metal liquid mixed layer are left to stand after the disturbance. Preferably, the rest time in step S34 is greater than 5 minutes. The metal is floated on the material to separate from the zinc metal liquid 11 by utilizing the difference in specific gravity. 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. 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 removed from the metal by 136683.doc -9- 201030152 and Oxide contamination. Referring to step S36, a step of squeezing and 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 molten metal η to flow out from the receiving unit 21, and the The slag blocking element 24 further stops the metal intervening or oxide that may not be completely removed from the liquid surface of the zinc metal liquid 11 to prevent it from flowing into the mold. 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 metal liquid 11 is greatly improved, wherein the recovery rate of the metal liquid can be increased to 82%, and the content of the zinc metal liquid can be reduced to 0.003. /〇. 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. The above embodiments are merely illustrative of the principles and effects of the invention and are not intended to limit the invention. Therefore, those skilled in the art can make modifications and changes to the above embodiments without departing from the spirit of the invention.
