Description
本发明涉及一种电解金属碎料的方法，具体说，是涉及一种直接电解金属碎料的方法。The present invention relates to a method of electrolyzing metal scrap, and more particularly to a method of directly electrolyzing metal scrap.
现在随着电器的不断普及，废旧金属的量也越来越多，但目前在精炼金属碎料的精炼工艺中，必须先将金属进行熔化铸成阳极板，再进行电解。而熔化铸造需要大量的焦碳，不仅产生废气污染大气，同时增加生产成本。现有技术中已有一些精炼金属的方法，如：中国专利局于2007年09月05日公开的专利申请号为200610163078.0的发明专利中公开了一种精炼金属铜的方法，该方法虽然可防止钝化现象、抑制电解液中悬浮阳极泥的形成、可制造高纯度电解铜，但仍然要先将铜熔化铸造成阳极板再进行电解。因此，现在急需一种不需要对金属进行熔化，可节省能源、降低电解成本的精炼金属特别是金属碎料的方法。Nowadays, with the continuous popularization of electrical appliances, the amount of scrap metal is increasing. However, in the refining process of refining metal scraps, it is necessary to first melt the metal into an anode plate and then perform electrolysis. Melting and casting requires a large amount of coke, which not only causes exhaust gas to pollute the atmosphere, but also increases production costs. There are some methods for refining metals in the prior art, such as the method of refining metallic copper, which is disclosed in the patent application of the patent application No. 200610163078.0 published by the Chinese Patent Office on Sep. 05, 2007. Passivation, inhibition of the formation of suspended anode mud in the electrolyte, high-purity electrolytic copper can be produced, but the copper must still be melt-cast into an anode plate and then electrolyzed. Therefore, there is an urgent need for a method of refining metal, particularly metal scrap, which does not require melting of the metal, which can save energy and reduce the cost of electrolysis.
发明内容Summary of the invention
针对现有技术存在的上述问题和需求，本发明的目的是提供一种可节省能源、成本低、工艺简单的直接电解金属碎料的方法。In view of the above problems and needs of the prior art, an object of the present invention is to provide a method for directly electrolyzing metal scrap which can save energy, has low cost, and is simple in process.
为实现上述目的，本发明采用如下技术方案：To achieve the above object, the present invention adopts the following technical solutions:
一种直接电解金属碎料的方法，是将金属碎料先压制成阳极板，然后将所述阳极板放入电解槽中与电解电源的正极相连，阴极与电解电源的负极相连，进行电解。A method for directly electrolyzing metal scraps is to first press the metal scrap into an anode plate, and then place the anode plate in an electrolytic cell connected to the positive electrode of the electrolysis power source, and the cathode is connected to the negative electrode of the electrolysis power source for electrolysis.
现有技术是先将金属碎料熔化后浇铸成阳极板，然后进行电解。在金属碎料熔化过程中会产生大量污染，例如：铜粉在熔化过程中要将其中的铅等杂质排放到空气中，会严重污染环境；同时，在熔化过程中会消耗大量能源；并且，在熔化过程中会使金属碎料进行氧化，如：铜粉氧化成氧化铜，而氧化铜的价值要远低于金属铜。In the prior art, the metal scrap is first melted, cast into an anode plate, and then electrolyzed. In the process of melting metal scraps, a lot of pollution will occur. For example, copper powder should discharge impurities such as lead into the air during the melting process, which will seriously pollute the environment; at the same time, it will consume a lot of energy during the melting process; During the melting process, the metal scrap is oxidized, for example, copper powder is oxidized to copper oxide, and the value of copper oxide is much lower than that of metallic copper.
而本发明采用压制成型的方法，将金属碎料压制成阳极板，不仅保证了现有设备下电解的正常进行，而且同时可以节省大量能源，并且没有熔化所致的污染问题，特别是以前排放到空气里的一些金属杂质现可得到资源化利用；例如：从废旧线路板粉碎所得到的铜粉与焊锡粉的混合物，现有方法为了防止焊锡中的铅、锡与铜形成合金，造成电解钝化现象，通常是将焊锡中的铅、锡通过熔炼炉排放到空气中，不仅不能回收利用，而且形成了重金属污染；而通过采用本发明方法进行电解处理，由于焊锡中的铅、锡都不能再电解，在电解过程中会沉积到阳极泥中，从而可实现从阳极泥中回收利用，不仅没有了重金属污染，还可将焊锡中的铅、锡资源化回收利用。可见，本发明相对于现有技术，具有显著性
进步和深远社会意义。The invention adopts the method of press forming, and presses the metal scrap into the anode plate, which not only ensures the normal electrolysis under the existing equipment, but also saves a lot of energy, and has no pollution problem caused by melting, especially the previous discharge. Some metal impurities in the air can now be recycled; for example, a mixture of copper powder and solder powder obtained by crushing waste circuit boards, the existing method for preventing lead, tin and copper from forming alloys in the solder, causing electrolysis Passivation, usually the lead and tin in the solder are discharged into the air through the melting furnace, not only can not be recycled, but also formed heavy metal pollution; and by the method of the present invention for electrolytic treatment, due to the lead and tin in the solder It can not be electrolyzed and deposited in the anode mud during the electrolysis process, so that it can be recycled from the anode mud. Not only does it have no heavy metal pollution, but also the lead and tin in the solder can be recycled and utilized. It can be seen that the present invention is significant compared to the prior art.
Progress and far-reaching social significance.
作为一种实施方案，以电解得到的金属作为阳极进行二次电解。由于金属碎料来源广、成份复杂，一次电解所得到的产品质量可能达不到高纯度要求，因此，以第一次电解所得到的金属产品作为阳极进行第二次电解，可确保得到的金属纯度要求。As an embodiment, the electrolysis obtained metal is used as an anode for secondary electrolysis. Due to the wide source of metal scrap and complex composition, the quality of the product obtained by primary electrolysis may not meet the high purity requirement. Therefore, the second electrolysis of the metal product obtained by the first electrolysis as the anode ensures the obtained metal. Purity requirements.
作为优选方案，所述金属在一次电解时采用不溶阳极材料作始极板。因为如果以第一次电解所得到的金属直接作为阳极进行二次电解，将会产生残极，因此以所述金属在一次电解时采用不溶阳极材料作始极板，则第一电解所得到的金属就包裹在不溶阳极的始极板上，这样在进行第二次电解时就不会存在残极，可提高生产效率，降低电解成本。Preferably, the metal uses an insoluble anode material as the starting plate for one electrolysis. Because if the metal obtained by the first electrolysis is directly used as the anode for secondary electrolysis, a residual electrode will be generated. Therefore, when the metal is used as the initial plate in the primary electrolysis, the first electrolysis is obtained. The metal is wrapped on the initial plate of the insoluble anode, so that there is no residual electrode during the second electrolysis, which can improve production efficiency and reduce electrolysis cost.
作为优选方案，在所述阳极板里夹设有连接金属碎料的连接网。由于阳极板的面积大，压制成的阳极板在电解过程中容易断裂，使电解过程无法完全完成。而在阳极板里夹设连接网后，连接网可保证阳极板在电解过程中不发生断裂。Preferably, a connecting net connecting the metal scraps is interposed in the anode plate. Due to the large area of the anode plate, the pressed anode plate is easily broken during the electrolysis process, so that the electrolysis process cannot be completely completed. After the connecting net is sandwiched in the anode plate, the connecting net can ensure that the anode plate does not break during the electrolysis process.
作为进一步优选方案，所述阳极板包括挂钩和金属板，所述连接网与挂钩固定连接，所述金属板是由连接网及压制在连接网表面的金属碎料形成。As a further preferred embodiment, the anode plate comprises a hook and a metal plate, the connecting net being fixedly connected to the hook, the metal plate being formed by a joining net and a metal scrap pressed on the surface of the joining net.
作为进一步优选方案，所述的连接网采用不溶阳极材料。由于不溶阳极材料在电解过程中不参与电解，故可以反复使用，可进一步降低生产成本。As a further preferred embodiment, the connecting net uses an insoluble anode material. Since the insoluble anode material does not participate in electrolysis during the electrolysis process, it can be used repeatedly, which can further reduce the production cost.
作为进一步优选方案，所述不溶阳极材料为金属钛或钛合金。因为钛金属或钛合金具有强度高、化学性能稳定、使用寿命长等优点。As a further preferred embodiment, the insoluble anode material is a metal titanium or a titanium alloy. Because titanium or titanium alloy has the advantages of high strength, stable chemical properties and long service life.
作为优选方案，在电解槽上安装清洗装置，使在电解过程中，对阳极板进行间断性表面清洗，以保持阳极板表面的清洁度。由于金属碎料中含有大量杂质，杂质在电解过程中会附着在阳极板表面，影响电解的正常进行，而对阳极板表面进行清洗，可保证电解的正常进行。Preferably, a cleaning device is installed on the electrolytic cell to intermittently clean the anode plate during the electrolysis to maintain the cleanliness of the surface of the anode plate. Since the metal scrap contains a large amount of impurities, the impurities will adhere to the surface of the anode plate during the electrolysis process, affecting the normal progress of the electrolysis, and cleaning the surface of the anode plate can ensure the normal progress of electrolysis.
作为优选方案，在所述阳极或/和阴极上套设有保护网套，所述的保护网套可以让电解液通过而固体颗粒不能通过。由于金属碎料的来源广、成份复杂，在电解过程中会产生很多固体颗粒杂质。通过在阳极或/和阴极上套设保护网套，可将固体杂质固定在阳极板里而不进入到电解液里，从而提高产品质量；同样，在阴极上套设保护网套，可以防止固体颗粒杂质进入到阴极表面，也可提高产品质量。Preferably, a protective mesh sleeve is sleeved on the anode or/and the cathode, and the protective mesh sleeve allows the electrolyte to pass through and the solid particles cannot pass. Due to the wide source and complex composition of metal scrap, many solid particulate impurities are generated during the electrolysis process. By arranging a protective net sleeve on the anode or/and the cathode, solid impurities can be fixed in the anode plate without entering the electrolyte, thereby improving product quality; likewise, a protective net sleeve is placed on the cathode to prevent solids. The entry of particulate impurities into the surface of the cathode also improves product quality.
作为进一步优选方案，所述清洗装置为高压冲洗装置或/和毛刷清洗装置。As a further preferred embodiment, the cleaning device is a high pressure flushing device or/and a brush cleaning device.
作为优选方案，所述阳极板由二块或二块以上拼接而成。因为若阳极板面积太大，对压制设备的要求会很高，如果采用二块或二块以上拼接而成，可以降低对压制设备的要求，容易实现工业化，但并不影响电解效果。Preferably, the anode plate is formed by splicing two or more pieces. Because if the anode plate area is too large, the requirements for the pressing equipment will be high. If two or more pieces are used, the requirements for the pressing equipment can be reduced, and industrialization can be easily realized, but the electrolytic effect is not affected.
作为优选方案，所述电解槽下部呈漏斗形状。由于金属碎料中含有大量杂质，杂质在
电解过程会不断沉积到电解槽中，当电解槽呈漏斗形状时，会将杂质汇集，容易排出。Preferably, the lower portion of the electrolytic cell has a funnel shape. Because the metal scrap contains a lot of impurities, the impurities are
The electrolysis process is continuously deposited into the electrolysis cell. When the electrolysis cell is in the shape of a funnel, the impurities are collected and easily discharged.
与现有技术相比，本发明具有如下有益效果：Compared with the prior art, the present invention has the following beneficial effects:
1)节省能源：由于在整个精炼过程中没有现有方法的熔化工艺，故可以节省一半以上的能源；1) Energy saving: Since there is no melting process of the existing method in the whole refining process, more than half of the energy can be saved;
2)没有污染：由于在整个精炼过程中没有熔化金属碎料的工艺，故没有污染排放；2) No pollution: no pollution discharge due to the process of melting metal scrap during the entire refining process;
3)节省成本：因减少了熔化工艺，故可降低一半以上的成本。3) Cost saving: By reducing the melting process, it can reduce the cost by more than half.
