Description

Technical Field

[0001] This utility model belongs to the technical field of hot-dip galvanizing production process, and in particular relates to an anti-solvent electrolytic separation device. Background Technology

[0002] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0003] In the hot-dip tinning process, an anti-solvent medium is required to chemically react with the base material. After treatment with the anti-solvent, the base material enters the tin pot for tin plating. Prolonged use during the production cycle can lead to impurities formed by the chemical reaction between the metal and the anti-solvent. Since the anti-solvent is entirely imported, it has a long supply cycle and is expensive. Its simultaneous use significantly hinders production costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1-2 An antisolvent electrolytic separation device comprises: a lifting bracket 2; a positive electrode plate 3 and a negative electrode plate 4, which can be suspended on the lifting bracket 2; the positive electrode plate 3 and the negative electrode plate 4 can extend into the antisolvent tank 1; a conductive support 6, which is provided on both the positive electrode plate 3 and the negative electrode plate 4; and a power supply 5, which is provided with a positive electrode post 51 and a negative electrode post 52. The positive electrode post 51 is connected to the conductive support 6 of the positive electrode plate 3 via a wire; and the negative electrode post 52 is connected to the conductive support 6 of the negative electrode plate 4 via a wire. Based on the chemical properties of the antisolvent, the metal substances in the antisolvent are decomposed by ionization, enabling the antisolvent to be reused.

[0022] Positive electrode 3 and negative electrode 4 are graphite plates. Graphite plates are used as conductive electrodes, dividing them into positive and negative electrodes, and a fixing bracket is fabricated on the graphite plate. This bracket is made of a metal material with electrical conductivity. Metal atoms are adsorbed onto the graphite electrode plates. To allow for the reuse of the graphite electrode plates, a scraper is provided to remove the impurity layer.

[0023] The positive electrode plate 3 and the negative electrode plate 4 are suspended on the lifting bracket 2 by the lifting rope 22. The lifting rope 22 is a flexible installation, which makes it easy to remove the positive electrode plate 3 and the negative electrode plate 4.

[0024] Both the positive plate 3 and the negative plate 4 are provided with two conductive supports 6. The two conductive supports 6 of the positive plate 3 are connected to the positive terminal 51 through two wires, making the conduction more stable and reliable.

[0025] The two conductive supports 6 of the negative electrode plate 4 are connected to the negative electrode post 52 through two wires, making the conductivity more stable and reliable.

[0026] The bottom of the hoisting bracket 2 is equipped with rollers, which facilitates the movement of the device and gives it mobility.

[0027] Graphite plates are used as conductive electrodes, divided into positive and negative electrodes, and fixed supports are fabricated on the graphite plates. These supports are made of metal and have electrical conductivity. Wires connect the supports to a power supply module 5. When the voltage is applied within a suitable range, the positive and negative electrodes of the graphite plates begin to decompose impurities in the antisolvent. Metal atoms are adsorbed onto the graphite plates. To allow for the reuse of the graphite plates, a scraper is provided to remove the impurity layer.

[0028] Regarding the selection of power supply 5, choosing DC power supply 5 makes it easier for chemical reactions to occur, and the degree of use of the graphite plate can be judged by the feedback of the current magnitude.

[0029] Graphite electrodes are selected based on the chemical properties of the antisolvent. The decomposition equipment is fixedly installed by making reasonable tooling, and impurities in the antisolvent are decomposed by relevant chemical methods, so that the antisolvent can be reused.

[0030] With the above structure, based on the chemical properties of the antisolvent, the metallic substances in the antisolvent are decomposed through ionization, allowing for the reuse of the antisolvent. During the decomposition process, a mechanical structure fixes the decomposition device, and an appropriate voltage is applied to achieve ion separation.
