Description

The present invention relates to an insulating support base.

In processes such as electrolytic refining, the cathode and anode are immersed in an electrolytic solution contained in an electrolytic bath, and a current is passed between the cathode and the anode in this state to deposit metal on the surface of the cathode and obtain a highly pure metal. are being collected. The electrolytic cell is provided with electrodes for supplying current between the cathode and the anode, and electric power is supplied to these electrodes from the outside.

The electrolytic cell as described above is usually installed while being supported by a frame, and the frame is usually made of metal. Not only that, but there is also the possibility that current will flow from the electrodes to the pedestal and leak.

Not only in electrolytic baths used for electrolytic refining and the like, but also in electrolytic baths in which an electric current flows, an insulating material is installed between the electrode of the electrolytic bath and a member that supports the electrolytic bath (for example, Patent Document 1). In the case of an electrolytic cell used for electrolytic refining, etc., a ceramic insulator in contact with the electrolytic cell and a metal (e.g. stainless steel) base for fixing this insulator to the frame are placed between the electrode and the frame of the electrolytic cell. A support member having a member is used.

Japanese Patent Application No. 2009-205491

However, since the supporting member as described above supports the electrolytic cell by means of the insulator made of ceramics, the insulating property can be improved. On the other hand, since the insulator is made of ceramics, it is fragile and requires careful handling. In addition, the support member that supports the electrolytic cell has a special shape that prevents the base member from coming into contact with the electrolytic solution in order to prevent the base member from being damaged by the highly corrosive electrolytic solution. For this reason, the insulator is not a commercial item but a made-to-order product, so even if damage occurs, it is not possible to immediately obtain a replacement. As a result, it is necessary to store a certain number of insulators in preparation for damage.

SUMMARY OF THE INVENTION An object of the present invention is to provide an insulating support that can stably support an electrode in an electrolytic cell for a long period of time.

The insulating support base of the first invention comprises a plurality of plate-shaped members made of an insulating material, the plurality of plate-shaped members are stacked and connected, and the plurality of plate-shaped members are connected to each other. It is characterized by comprising a second member that is substantially similar in shape to the first member in a plan view and has a different size .
The insulating support base of the second invention comprises three or more plate-like members made of an insulating material, and the plurality of plate-like members are stacked and connected . The plurality of plate-shaped members are stacked so as to form a portion , and the plurality of plate-shaped members are chamfered at the end of the upper surface of the portion to be the protrusion .
The insulating support base of the third invention is the second invention , wherein the plurality of plate-like members comprise a first member and a second member having a shape substantially similar to the first member and a size different from that of the first member in a plan view. It is characterized by having
An insulating support base according to a fourth invention is characterized in that, in the first or second invention, the plurality of plate-like members are rectangular in plan view.

In the following, as a representative case, the case of using as a support stand for insulating between the electrodes provided in the electrolytic bath for electrolytic refining and the stand supporting the electrolytic bath will be described.

<Electrolyzer D for Electrolytic Refining>
First, before describing the insulating support base 10 of the present embodiment, a brief description will be given of how the insulating support base 10 of the present embodiment is used.

In FIG. 5, symbol D indicates an electrolytic cell for electrolytic refining. A frame F for supporting the electrolytic bath D is provided around the electrolytic bath D. As shown in FIG.
As shown in FIG. 5, the side surface of the electrolytic bath D is provided with an electrode T for externally supplying electric power to a bus bar or the like that supplies electric current to the cathode and anode immersed in the electrolytic bath D. As shown in FIG. An insulating support base 10 is provided between the electrode T and the base F. That is, the electrodes T of the electrolytic cell D are supported by the frame F via the insulating support 10 .

With the structure as described above, the electrode T of the electrolytic cell D can be insulated from the frame F by supporting the electrode T of the electrolytic cell D with the insulating support base 10 . Then, even if a current is supplied from the electrode T to the cathode or the anode, it is possible to prevent electric leakage from the electrode T to the frame F.

The insulating support base 10 is fixed to the frame F with bolts, screws, or the like, the details of which will be described later.

<Insulating support base 10>
As shown in FIG. 1, the insulating support base 10 of this embodiment is formed by stacking a plurality of plate members 11 . The plate member 11 of the insulating support base 10 includes a square first member 12 (see FIG. 2A) and a square second member 13 larger than the first member 12 (see FIG. 2B). ) and . That is, the second member 13 is a member similar in shape to the first member 12 but different in size. Both the first member 12 and the second member 13 of the plate member 11 are made of a material having insulating properties and corrosion resistance.

The first member 12 and the second member 13 are provided with female screw holes 12h and 13h. The female threaded holes 12h and 13h are provided for screwing bolts and screws when connecting the first members 12 to each other, the second members 13 to each other, and the first member 12 and the second member 13 to each other. The female screw holes 12h and 13h are provided so that when the first member 12 and the second member 13 are superimposed so that the centers C thereof are aligned, the female screw holes 12h and 13h overlap when viewed from the overlapping direction. ing.

For example, as shown in FIGS. 1 and 2, the female threaded hole 12h of the first member 12 is formed at the center C of the first member 12, and the female threaded hole 13h of the second member 13 is formed at the center C of the second member 13. do. If the first member 12 and the second member 13 are arranged so that their centers C are on the same axis CL, the first member 12 and the second member 13 can be connected by screws or the like.

Further, the positions where the female threaded hole 12h of the first member 12 and the female threaded hole 13h of the second member 13 are formed are not limited to the positions described above. When the female threaded hole 12h of the first member 12 and the female threaded hole 13h of the second member 13 are arranged so that their centers C are on the same axis CL, the female threaded hole 12h and the female threaded hole 13h are positioned so that they can overlap each other. should be formed. Moreover, all the first members 12 do not have to have the female screw holes 12h at the same positions, and all the second members 13 do not have to have the female screw holes 13h at the same positions. For example, as shown in FIG. 3, a portion of the first member 12 and a portion of the second member 13 have female screw holes 12h and 13h formed at the center C of the first member 12 and the second member 13, and some The first member 12 and some of the second members 13 may have female screw holes 12h and 13h at positions displaced from the center C.

Since the plate-like member 11 is formed of the first member 12 and the second member 13 as described above, the first member 12 and the second member 13 are alternately stacked and screwed into the female threaded hole 12h and the female threaded hole 13h. are screwed together, it is possible to form the insulating support base 10 in which a plurality of first members 12 and second members 13 are connected in a stacked state.

Then, the insulating support base 10 is placed on the base F, and the bolts B or the like are inserted through the through holes h provided in the base F, and are inserted into the female screw holes 12h of the first member 12 and the female screw holes 13h of the second member 13. By screwing bolts B or the like, the insulating support base 10 can be fixed to the frame F (see FIG. 5).

Further, a through hole is provided in the electrode T or a member that holds the electrode T, and a screw or bolt is inserted through the through hole, and the screw or bolt is inserted into the female screw hole 12h of the first member 12 or the female screw hole 13h of the second member 13. The electrode T and the insulating support base 10 can be fixed by screwing the bolts. Then, the electrode T can be supported by the frame F in a state of being insulated from the frame F through the insulating support base 10 .

Moreover, since the insulating support base 10 is formed by simply stacking the plate-like first member 12 and the second plate member 13 and connecting them with bolts, screws, or the like, the insulating support base 10 can be formed easily and in a short time. . In addition, since the electrodes T, the frame F, and the insulating support base 10 are only fixed by bolts, screws, or the like, it is difficult to install the insulating support base 10 on the frame F and to fix the electrodes T and the insulating support base 10 together. etc. can be carried out easily and in a short time. Therefore, when the insulating support base 10 is damaged, replacement and maintenance can be performed easily and in a short time.

In addition, since the installation height of the electrode T with respect to the pedestal F can be adjusted simply by changing the number of the first member 12 and the second member 13 to be used, even if there is deformation or manufacturing error in the pedestal F or the electrolytic cell D, It becomes possible to install the electrolytic cell D on the frame F in an appropriate posture.

Furthermore, since the second member 13 is larger than the first member 12, if the first member 12 and the second member 13 are alternately stacked, the peripheral edge of the second member 13 can be secured to the side surface of the insulating support base 10. A plurality of projecting protrusions 15 are formed (see FIG. 1). If such protrusions 15 are formed, the electrolytic solution dripping or adhering to the insulating support base 10 can be easily dropped from the tips of the protrusions 15 . In this case, compared to the case where the electrolyte flows along the side surface of the insulating support 10, it is easier to prevent the electrolyte from entering the gap where the lower surface of the insulating support 10 and the upper surface of the frame F are in contact. . As a result, it is possible to prevent the bolts or the like connecting the insulating support base 10 and the frame F from being corroded by the electrolytic solution or the like. Similarly, it becomes easier to prevent the electrolytic solution from entering the gap where the first member 12 and the second member 13 are in contact with each other. As a result, it is possible to prevent the bolts or the like connecting the first member 12 and the second member 13 from being corroded by the electrolytic solution or the like.

<About the first member 12 and the second member 13>
Although the second member 13 is larger than the first member 12 in the above example, the second member 13 may be smaller than the first member 12 . In this case, when the insulating support base 10 is formed by stacking the first member 12 and the second member 13, the stacking method may be reversed.

Moreover, the shape of the first member 12 and the second member 13 is not limited to the above-described square. For example, as shown in FIG. 4, the first member 12 and the second member 13 may be rectangular, triangular, circular, or polygonal.

Also, the first member 12 and the second member 13 do not necessarily have similar shapes. The first member 12 and the second member 13 may have exactly the same shape and size. Even in this case, if the first member 12 and the second member 13 are not circular, the first member 12 and the second member 13 should be arranged so that the above-described projecting portion 15 is formed by adjusting the way of stacking them. can be stacked to form the insulating support base 10 .

Furthermore, the first member 12 and the second member 13 do not have to form the female threaded holes 12h and 13h in all the first members 12 and the second members 13 . A part of the first member 12 and the second member 13 may be formed with holes without threads instead of the female threaded holes 12h and 13h. Even in this case, if the female screw holes 12h and 13h are formed in some of the first members 12 and some of the second members 13, the insulating support base connecting the plurality of first members 12 and the second members 13 10 can be formed. Also, the insulating support base 10 can be fixed to the frame F and the electrode T with bolts or the like.

Furthermore, the first member 12 and the second member 13 are preferably chamfered or rounded (see FIG. 1). If the peripheral portion is chamfered or R-processed, even if the electrolyte or the like drips onto the first member 12 and the second member 13, the electrolyte or the like can be smoothly dropped downward. The chamfering or R processing may be performed on both surfaces of the first member 12 and the second member 13, or may be performed only on one surface side (see FIG. 1). If only one surface is chamfered or rounded, if the first member 12 and the second member 13 are overlapped so that the chamfered or rounded surface faces upward, the electrolytic solution etc. can be smoothly dropped downward (see FIG. 1).

<Regarding Projection 15>
In the above example, the first member 12 and the second member 13 are stacked such that the protruding portion 15 formed by protruding the peripheral portion of the second member 13 is formed on the side surface of the insulating support base 10 . The number, position, etc. of the protruding portions 15 are not particularly limited. As described above, the first members 12 and the second members 13 may be alternately stacked to form a plurality of protrusions 15, or as shown in FIG. Then, two pieces) may be provided, and a desired number of protrusions 15 may be provided at desired positions. Moreover, the first member 12 and the second member 13 may be overlapped so that the protruding portion 15 is formed at a position near the upper surface of the insulating support base 10, or the first member 12 and the second member 13 may be overlapped at a position near the lower surface of the insulating support base 10. The member 12 and the second member 13 may be overlapped.

In particular, the plurality of protrusions 15 are provided so as to be formed at a position (that is, above the lower surface of the insulating support base 10) away from the lower surface of the insulating support base 10 (that is, the surface that contacts the pedestal F). is desirable. In this case, the electrolytic solution or the like can be dropped from the projecting portion 15 to a position apart from the position where the base F and the insulating support base 10 are in contact with each other. This makes it difficult for the electrolyte that has fallen onto the frame F to enter through the gap between the frame F and the lower surface of the insulating support base 10, so that the bolts or the like connecting the frame F and the insulating support base 10 do not allow the electrolyte, etc., to enter. It becomes easy to prevent it from corroding by.

<Regarding the plate member 11>
In the above example, the plate member 11 forming the insulating support base 10 has the first member 12 and the second member 13 . However, the plate member 11 includes, in addition to the first member 12 and the second member 13, a third member and a fourth member which are similar in shape to the first member 12, and which are similar in shape to the first member 12 but different in size. You may have many plate-shaped members. Moreover, the first member 12 and the second member 13 of the plate-like member 11 may not have similar shapes, and the plate-like member 11 may have a plurality of plate-like members having different shapes. Of course, the plate-like member 11 may have only one shape of plate-like member.

<Material of plate member 11>
The first member 12 and the second member 13 of the plate-like member 11 have insulating properties and corrosion resistance to the electrolytic solution when used in the electrolytic bath D for electrolytic refining of the insulating support base 10 of the present embodiment. It is desirable to be formed of a material having For example, it can be made of a plastic material such as polypropylene or Teflon (registered trademark), FFU, FRP, or the like. In particular, polyvinyl chloride (PVC) is desirable because it is readily available.

When used in a place where corrosion resistance is not required, the first member 12 and the second member 13 of the plate member 11 do not necessarily have to be made of a material having corrosion resistance. The first member 12 and the second member 13 of the plate-like member 11 may be made of an appropriate material according to the environment in which the insulating support base 10 is used.

The first member 12 and the second member 13 do not necessarily have to be made of the same material, and both may be made of different materials. If the first member 12 and the second member 13 are made of different materials, there is an advantage that a material that is easy to process can be selected for the first member 12 . On the other hand, if the first member 12 and the second member 13 are made of the same material, there is an advantage that they can be manufactured at low cost.

The insulating support base of the present invention is suitable as a member for supporting an electrode of an electrolytic cell in a state of being insulated from other conductors such as a mount.
