Description

  The present invention relates to a hook structure of an electrode plate transport device, and more specifically, a number of electrode plates are suspended and moved to above the electrolytic cell, and moved up and down at that position to insert the electrode plate into a predetermined position of the electrolytic cell. In addition, the present invention relates to a hook structure of an electrode plate conveying device in electrolytic purification in which an electrode plate after electrolysis is pulled up and conveyed.

  For electrolytic refining of metals such as copper and zinc, a plurality of (usually about 20 to 60 in the case of Cu) stainless steel cathode plates (permanent cathodes) and anode ears are provided in an electrolytic cell in which an electrolytic solution is stored. It is performed by immersing the mold (anode) alternately in parallel and applying a voltage. The loading, lifting, and transport of these many electrode plates to the electrolytic cell are performed in a state where the electrode plates are suspended by hooking the support portions provided on the electrode plates by the hooks of the electrode plate transport device. . That is, the electrode plate transport device having a hook capable of lifting a large number of electrode plates is moved horizontally to the upper side of the electrolytic cell, and the electrode plate is moved into the electrolytic cell by moving the suspension device of the electrode plate transport device at that position. Is loaded or pulled up to a predetermined position. Then, the permanent cathode plate on which the target metal has been electrodeposited to a predetermined thickness is transported to the stripper receiving port conveyor by the electrode plate transport device, and the surface is electroplated by the stripper. The worn metal is stripped off. The permanent cathode that has been peeled off is transferred to a conveyor at a stripper carry-out port, transported by an electrode transport device, adjusted for properties, and again subjected to electrolytic purification.

  As a hook of a conventional electrode plate transport device, for example, those described in JP-A-6-173067 (Patent Document 1) and JP-A-9-249986 (Patent Document 2) are generally used. It was. That is, as shown in FIG. 8, the hook 150 of the conventional electrode plate transport device is provided at the tip of the rod R suspended from the electrode plate transport device (not shown), and the shape of the hook 150 is substantially L-shaped. It was a mold shape. Then, the cross bar Ka of the permanent cathode or the ear part of the anode is hooked by this hook part and suspended.

JP-A-6-173067 Japanese Patent Laid-Open No. 9-249986

  However, the hook 150 of the conventional electrode plate transport device having such a bowl shape has a flat hook surface 151 and the cross-sectional shape of the cross bar Ka of the permanent cathode K is substantially as shown in FIG. Because of the oval oval shape, when the cross bar Ka is hooked on the hook 150 and the permanent cathode K is suspended, the hook surface 151 and the cross bar Ka come into contact at a single point, and the permanent There was a problem that the cathode K was easily shaken and not easily stopped. For this reason, it is necessary to wait for the permanent cathode K to stop shaking and to be surely stationary when transporting, and there is a waiting time until the permanent cathode K is stationary in each step such as immersion in and removal from the electrolytic layer. It was. Therefore, it took about 30 minutes to replace the permanent cathode K.

  Therefore, in view of the above-mentioned problems, the present invention suppresses the occurrence of shaking of the electrode plate suspended at the time of loading and lifting of the electrode plate such as the permanent cathode K and the anode into the electrolytic cell and the conveyance thereof, and the electrode plate is suspended. It is an object of the present invention to provide a hook structure for an electrode plate transport device in which the electrode plate does not easily swing.

In order to solve the above problems, the present invention according to claim 1 suspends an electrode plate by supporting a support portion provided on an electrode plate to be subjected to electrolytic purification, thereby conveying a plurality of electrode plates. At the same time, in the hook structure of the electrode plate transport device that performs loading and unloading to the electrolytic cell, the hook is provided at the tip of the rod disposed in the electrode plate transport device, and the support portion is provided on the hook surface that supports the support portion. And has a substantially V-shaped inclined surface inclined toward the center of the hook surface, and the inclined surface is 20 to 60 ° with respect to the horizontal direction. A recess having an inclination angle is provided.
The hook surface that supports and hangs the crossbar or the ear part, which is the support part of the electrode plate, is not flat, but the support part of the electrode plate is supported at two locations by providing a recess. Accordingly, the electrode plate can be stably supported regardless of the cross-sectional shape of the support portion of the electrode plate, and the occurrence of shaking can be prevented. Further, the concave portion of the hook surface is formed in a substantially V-shaped cross section, and the angle of the inclined surface is set to an inclination angle of 20 to 60 ° with respect to the horizontal direction. As a result, the electrode plate support is supported at two locations on the two inclined surfaces, so that the electrode plate is immediately stabilized and firmly supported by the hook without shaking as before.

In order to solve the above problems, the present invention according to claim 2 suspends an electrode plate by supporting a support portion provided on an electrode plate to be subjected to electrolytic purification, thereby conveying a plurality of electrode plates. At the same time, in the hook structure of the electrode plate transport device that performs loading and unloading to the electrolytic cell, the hook is provided at the tip of the rod disposed in the electrode plate transport device, and the hook surface that supports the support portion is the support portion. And a concave portion having a shape to be supported in surface contact with the substrate.
The support portion is supported by surface contact by forming a concave portion conforming to the sectional shape of the support portion of the electrode plate on the surface of the hook. As a result, the electrode plate is stably suspended without shaking, and immediately transported, loaded, and taken out.

  According to the hook structure of the electrode plate transport device according to the present invention, the electrode plate support portion and the electrode plate support portion on the surface of the hook that supports the electrode plate support portion provided at the tip of the electrode plate transport device or Since the concave portion is formed so as to be supported by surface contact, the electrode plate can be stably supported because the support portion does not swing on the hook surface when the electrode plate is suspended. Immediately stops. This eliminates the need for a total waiting time of about 30 minutes until the electrode plate shakes in a series of operations in the electrode plate replacement work of moving, loading and unloading to the electrolytic cell. There is an effect that efficiency is greatly improved.

Hereinafter, a preferred embodiment of a hook structure of an electrode plate transport device according to the present invention will be described in detail with reference to the drawings.
First, an outline of electrolytic purification equipment will be described with reference to the drawings. As shown in FIG. 1, the electrolytic baths 30 in which an electrolytic solution such as an aqueous copper sulfate solution is stored are arranged in a large number and arranged on the floor so that the entire frame is fixed and the legs 34 do not rattle. It has been. In each electrolytic cell 30, the electrode plate 22 is immersed, and electrolysis is performed by applying a voltage. As shown in FIG. 2, the electrode plate 22 includes an anode A that is an anode side electrode and a permanent cathode K that is a cathode side electrode, and the anode A and the permanent cathode K are alternately supported in parallel to each other in the electrolytic cell 30. Placed in.

  Here, the electrode plate 22 will be described. As shown in FIG. 2, the electrode plate 22 is composed of a permanent cathode K and an anode A, and a high-purity metal is electrodeposited on the surface of the permanent cathode K by electrolytic purification, and is peeled off to be processed into a product. The permanent cathode K is a stainless steel cathode electrode having a substantially rectangular flat plate shape. The permanent cathode K is provided with a cross bar Ka on the upper edge of the electrolytic cell 30 for energization, and edge strips 5 on both sides. Is inserted. Two rectangular windows Kb are provided on the upper side of the permanent cathode K near the lower side of the crossbar Ka. The permanent cathode K is lifted by inserting and hooking a pair of cathode hooks F1 and F1, which will be described later, attached to the electrode plate transport device into the window Kb.

On the other hand, the anode A is a substantially square plate-like anode electrode, and a pair of ears Aa and Aa projecting in the left-right direction is formed on the anode A. The ears Aa and Aa are hooked on the upper edge of the electrolytic cell 30 to be energized and hooked to a pair of anode hooks F2 and F2 for transport. A concave portion Ab that is recessed in a concave shape is formed between the pair of ear portions Aa and Aa. During electrolytic purification, the metal is ionized from the anode A side and eluted into the electrolytic solution, which is deposited on the surface of the permanent cathode K to purify the metal.
Such permanent cathodes K and anodes A are suspended and conveyed by the cathode hooks F1 and the anode hooks F2, respectively, in a state of being arranged in multiple layers at a constant interval.

As shown in FIG. 1, an electrode plate transport device 10 is suspended by an overhead crane (not shown) via four wires W above the electrolytic cell 30, and the electrode plate transport device 10 is mounted on the ceiling. The crane can be moved in the front-rear and left-right directions.
As best shown in FIG. 4, the electrode plate transport device 10 includes an anode frame 11, a cathode frame 15, and a lifting frame 17, and is provided on both sides of the anode frame 11 in the longitudinal direction. A hook is hooked on the four suspension members 14 (only one side is shown in FIG. 4), and the entire apparatus is suspended by the wire W. Although not shown, a winding mechanism for winding the wire W above the wire W, and a position-controlled horizontal moving means for horizontally moving the electrode plate conveying device 10 in the vertical direction X or the horizontal direction Y of the electrolytic cell 30. Position control means for stopping the frame on which the hoisting machine is mounted above the desired electrolytic cell 30 is provided. Electrode plate conveying apparatus 10 configured in this manner is such that the electrolysis is finished from the upper part of each electrolytic cell 30 from the upper part of a supply conveyor (not shown) that supplies electrode plate 22 and from the upper part of each electrolytic cell 30 at a predetermined position. The permanent cathode K on which the target metal is electrodeposited is moved horizontally between the upper part of the conveyor 40 that conveys the permanent cathode K to a stripping device (not shown), and is moved up and down in the height direction (Z direction) to obtain a number of permanent cathodes K and anodes. A is suspended and loaded into or removed from the supply conveyor, the electrolytic cell 30, and the conveyor 40.

The anode frame 11 has a frame structure that is framed by a steel material such as H steel, for example, and a large number of rods R are disposed on both side surfaces thereof at regular intervals along the longitudinal direction. . The rod R can be rotated vertically by a rotation mechanism using a power cylinder (not shown) as a drive source, and an anode hook F2 for suspending the anode A is provided at the tip of the rod R.
An elevating frame 17 is disposed inside the anode frame 11 via a connecting frame 11a. Similarly to the anode frame 11, the elevating frame 17 has a frame structure framed with a steel material, and includes an elevating mechanism 20 for elevating a cathode frame 15 described later.
A cathode frame 15 is attached to the elevating frame 17 via an elevating mechanism 20 so that the cathode frame 15 can be moved up and down. It is installed. The rod R can be rotated vertically by a rotation mechanism using a power cylinder (not shown) as a drive source, and a cathode hook F1 for suspending the permanent cathode K is provided at the tip of the rod R.

  The elevating mechanism 20 includes a ball screw nut 21 and a shaft 22, and is arranged at two locations on the elevating frame 17. The elevating frame 17 is provided with a drive speed reducer 23 for operating the elevating mechanism 20, and the power from the drive speed reducer 23 is transmitted to the two shafts 22 via the drive shaft 21a. Yes. When the shaft 22 is rotated by the power from the drive speed reducer 23, the ball screw nut 21 screwed to the shaft 22 moves in the vertical direction, and thereby the cathode frame 15 is raised and lowered. The cathode frame 15 moves up and down along a guide rod (not shown) suspended from the lifting frame 17 when moving up and down, so that the cathode frame 15 moves up and down stably.

  The elevating frame 17 is provided with a moving device 25 that horizontally moves the cathode frame 15 relative to the anode frame 11 in the longitudinal direction. The moving device 25 is configured to move the cathode frame 15 by a power source such as a jack. In this way, the cathode frame 15 can be moved in the horizontal direction because the anodes A are set on both sides of the electrolytic cell 30, while the anode frame 11 and the cathode frame 15 are alternately positioned. This is because the cathode hook F1 or the anode hook F2 is arranged, and in order to pull up the anodes A on both sides, it is necessary to reverse the arrangement order of the cathode hook F1 and the anode hook F2. . Therefore, the anodes A arranged on both sides of the electrolytic cell 30 are pulled up at a rate of once every two cycles.

  Now, a pair of cathode hooks F1 and F1 provided at the tip of the rod attached to the cathode frame 15 is paired on the left and right sides, and an L-shape is provided at the tip of the rod R as shown in FIGS. The surface shape of the permanent cathode K that supports the cross bar Ka of the permanent cathode K is a concave portion 5 having a V-shaped cross section that is recessed near the center. The cathode hooks F1 and F1 can be rotated 90 degrees perpendicular to the axis by a rotation mechanism using a power cylinder (not shown) that is electrically controlled as a drive source. When the cross bar Ka is hooked by the hook F1 formed in this manner and the permanent cathode K is suspended, the cross bar Ka is formed by a substantially V-shaped inclined surface that is inclined toward the center of each of the recesses 5. Guided and supported by the two contact portions 5a and 5a on the lower surface of the crossbar Ka. As a result, the crossbar Ka is supported in a stable state without swinging on the surface of the cathode hook F1, and the permanent cathode K is immediately stopped when the crossbar Ka is hooked on the cathode hook F1. To do.

  The inclination angle θ of the inclined surface of the recess 5 is preferably set to an inclination angle of 20 to 60 ° with respect to the horizontal direction. With this structure, the crossbar Ka can be supported at two locations in the recess 5 of the cathode hooks F1, F1.

  As another embodiment, the cathode hook F1 may be shaped as shown in FIG. That is, the shape of the concave portion 5 is set so as to come into surface contact with the cross bar Ka, thereby supporting the cross bar Ka. By forming the shape of the recess 5 so as to be in surface contact with the cross bar Ka, the cross bar Ka is fitted into the recess 5, and the swing of the permanent cathode K is reliably suppressed.

  On the other hand, as shown in FIG. 4, the anode hooks F <b> 2 are provided at the tips of rods R that are rotatable about the axis of the anode frame 11 and are provided at regular intervals. The anode hooks F2 and F2 can be rotated 90 degrees perpendicular to the axis by a mechanism using a power cylinder (not shown) that is electrically controlled as a drive source, similarly to the above-described cathode hooks F1 and F1. The anode hooks F2 and F2 can also have the same shape as the cathode hook F1. That is, the anode hooks F2 and F2 are formed in an L shape, and the surface shape that supports the ear portion Aa of the anode A is the concave portion 5 in which the vicinity of the central portion is recessed. When the ear Aa is hooked by the hook F2 and the anode A is suspended, the ear Aa can be supported at two locations on the inclined surface that is inclined in a substantially V shape toward the center of the recess 5. . As a result, the ear Aa is supported in a stable state without swinging on the surface of the anode hook F2, so that when the ear Aa is hooked on the anode hook F2, the anode A immediately It will be stationary.

Next, the operation when the permanent cathode K is lifted by the cathode hook F1 will be described. As described above, a large number of permanent cathodes K and anodes A are arranged in the electrolytic cell 30 at regular intervals. Then, the electrode plate transport device 10 is moved and stopped at a predetermined position above the electrolytic cell 30, and the cathode frame 15 is lowered by the elevating mechanism 20 so that the lower end of the cathode hook F 1 is provided above the anode plate A. It is located above the recess Ab (see FIG. 7).
When the cathode hook F1 is lowered to a position slightly lower than the cross bar Ka, the rod R is rotated by 90 degrees by a power cylinder (not shown) to cause the cathode hook F1 to enter the window Kb. Then, the cathode frame 15 is raised by the lifting mechanism 20 to suspend the permanent cathode K. At this time, as shown in FIG. 5 (a), the surface of the cathode hook F1 is provided with a concave portion 5 having a concave central portion, so that the crossbar Ka is substantially V-shaped so as to incline toward the central portion. And are firmly supported at two locations 5a and 5a on the lower surface of the cross bar Ka. As a result, the swing of the permanent cathode K is stopped, so that the transfer operation can be performed immediately. The anode A is suspended and moved by the same operation, but the operation is almost the same as that of the permanent cathode K, and the description thereof is omitted.

  As described above, the preferred embodiment of the present invention has been described in detail.
