According to the utility model, damage to human bodies and equipment, which is caused by material leakage of the electrolysis bath, is avoided, production safety is ensured, the service life of the equipment is prolonged, and other components, except the anode, of the electrolysis bath can be reused, so that equipment cost is saved.
Description
Technical field
The utility model relates to a kind of electrolyzer, especially a kind of metal lithium electrolytic bath for the electrolytic metal lithium.
Background technology
Owing to utilize the low-melting characteristic of fused electrolyte LiCl-KCl, the ionogen of compositions of mixtures is not volatile, and up to now, the industrial production of metallic lithium all adopts this ionogen electrolysis precipitating metal lithium on electric tank cathode.Electrolyzer is comprised of cell body, anode and negative electrode, and anode is arranged in the middle of the cell body, and negative electrode is around the anode setting, and negative electrode is installed in the middle part of cell body inwall.When direct current passes through electrolyzer, oxidizing reaction occurs at anode and solution interface place, anode is separated out chlorine and is floated on bath surface.At negative electrode and solution interface place reduction reaction occurs, at negative electrode precipitating metal lithium.Because negative electrode is installed in the middle part of cell body inwall by insulating material, ionogen temperature after energising raises, excess Temperature damages insulating material, and owing to expand with heat and contract with cold, insulating material easily breaks away from cell body, forms the slit, causes the interior ionogen of cell body easily from the negative electrode seepage, cause the electrolyzer corrosion, electrolyzer short, leakiness material in work-ing life.
The utility model content
Technical problem to be solved in the utility model is: a kind of metal lithium electrolytic bath that is difficult for side leakage is provided.
The technical scheme that its technical problem that solves the utility model adopts is: metal lithium electrolytic bath, comprise cell body, be positioned at the middle anode of cell body, center on the negative electrode that anode arranges, described anode, negative electrode all are connected with the cell body insulation, also comprise negative contact, described negative contact one end is fixed on the negative electrode, and an other end is fixed on cell body top.
Described anode lower surface is installed in the bottom in the middle of the cell body.
Described anode is cylindrical, and described negative electrode is to be enclosed within the outer cylindrical tube of anode, and described negative contact is from cell body top to the cell body intermediate, inclined.
Described negative contact has two, is arranged symmetrically in the both sides of anode.
Described cell body comprises upper shell, lower shell and base, is connected with flange between described upper shell and the lower shell, and lower shell is installed on the base.
Described cell body material is carbon steel.
The beneficial effects of the utility model are: negative electrode is fixed on cell body top by negative contact, avoids the cell body corrosion, and ionogen can from the negative electrode seepage, not solve the person that electrolyzer leakage material causes, the infringement of equipment.And electrolyzer is except anode, and miscellaneous part all can be reused, and has saved equipment cost.
Description of drawings
Fig. 1 is the structural representation of metal lithium electrolytic bath;
Fig. 2 is along the sectional view of A-A among Fig. 1;
Indicate among the figure: 1-cell body, 11-upper shell, 12-lower shell, 13-base, 2-anode, 3-negative electrode, 4-negative contact.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, metal lithium electrolytic bath, comprise cell body 1, the negative electrode 3 that is positioned at anode 2 in the middle of the cell body 1, arranges around anode 2, described anode 2, negative electrode 3 all are connected with cell body 1 insulation, also comprise negative contact 4, described negative contact 4 one ends are fixed on the negative electrode 3, and an other end is fixed on cell body 1 top.
Because electrolytical liquid level generally is lower than cell body 1 top, negative contact 4 can not be immersed in the ionogen with the connection portion of cell body 1, so cell body 1 can not form the slit, ionogen can be from the connection portion side leakage of negative contact 4 with cell body 1; Avoided negative contact 4 to be positioned at cell body 1 middle part because electrolytical pressure can damage insulating material, even be higher than negative contact 4 and negative contact 4 is positioned at cell body top ionogen liquid level, ionogen is less to the pressure of insulating material, avoid electrolytical pressure to make insulating material and cell body 1, negative contact 4 form the slit, equally also avoided electrolytical side leakage.General cell body 1 material is stainless steel or carbon steel, is higher than negative contact 4 tops for fear of the ionogen liquid level and causes ionogen side leakage negative contact 4 and cell body 1 preferably to seal by the part that insulating material is fixed on cell body 1.Avoid chlorine leakage in order better to collect chlorine, cell body 1 top can be provided with the lid of pipeline.
Described anode 2 can be multiple with the shape of negative electrode 3, in order to increase anode 2, negative electrode 3 and electrolytical contact area, improves electrolytic efficiency.As preferred embodiment, as shown in Figure 1, 2, described anode 2 is cylindrical, and described negative electrode 3 is for being enclosed within the cylindrical tube outside the anode 2, and described negative contact 4 is from cell body 1 top to cell body 2 intermediate, inclined.
Negative contact 4 can be one or more, as long as can fix negative electrode 3, as a kind of optimal way is, as shown in Figure 1, 2, described negative contact 4 has two, is arranged symmetrically in the both sides of anode 2.
Cell body 1 can be as a whole, the installation of the cell body 1 inconvenient electrode of an integral body, dismounting for the ease of electrolyzer, as preferred embodiment, as shown in Figure 1, 2, described cell body 1 comprises upper shell 11, lower shell 12 and base 13, is connected with flange between described upper shell 3 and the lower shell 4, and lower shell 4 is installed on the base 13.Described cell body 1 comprises upper shell 11, lower shell 12 and base 13, is connected with flange between described upper shell 3 and the lower shell 4, and lower shell 4 is installed on the base 13.Base 13 is generally piled up by refractory brick, and anode 2 is installed on the base 13, and negative electrode 3 is installed on the upper shell 11, and negative electrode 3 is installed in electrolyzer upper shell 11, and installation, convenient disassembly and can reuse are saved the electrolyzer cost of investment equally.Because anode 2 is installed on the base 13, but anode 2 lower surface coated insulation materials, and in order to save cost, base 13 adopts refractory brick to pile up.
Cell body 1 material can be the materials such as stainless steel, but stainless material is more expensive, and in order to save material, described cell body 1 material is carbon steel.Reduced the manufacturing cost of electrolyzer.
