Description

[Detailed Description of the Invention] This invention relates to a hanging device for an electrode plate inserted into an electrolytic cell for electrolytically refining metal.

In a typical metal electrolytic refining factory, electrolytic refining is carried out by arranging a large number of anodes (anode plates) and cathodes (cathode plates) alternately in an electrolytic cell. At this time, as the electrolytic refining progresses, the anode dissolves and conversely a precipitation reaction occurs at the cathode, so it is necessary to lift and lower the anode and cathode for replacement as appropriate.

In this case, the anode and cathode have different shapes, as shown in FIGS. 1 and 2, respectively, and the positions on which the hanging hooks are hung are different. That is, in the case of the anode A shown in FIG. 1, the positions are a and a, and in the case of the cathode K shown in FIG. are different. Therefore, each electrode plate must be hung using hanging devices having different hook widths.

Conventionally, a dedicated hanging device is prepared for each electrode plate, and each electrode plate is hung using its own dedicated device, which requires two hanging devices. It was hot.

This idea was made in view of the above circumstances,
To provide a hanging device which can automatically adjust the hook width and can be used for bipolar plates.

This invention is characterized in that the distance between a pair of parallel hanging beams can be adjusted using an adjustment mechanism, and a number of hanging hooks that can be rotated by a turning mechanism are provided on the bottom surface of each hanging beam. An embodiment of this invention will be described in detail with reference to the drawings.

FIG. 3 shows the overall configuration of the device of the embodiment. In the figure, reference numerals 1 and 1 indicate a pair of parallel suspension beams, and these suspension beams 1 and 1 are designed to be suspended from an overhead crane or the like. , the mutual spacing can be adjusted by electric cylinders 2, 2. 3, 3 are guide rods for guiding the suspension beams 1, 1 whose spacing is adjusted.

Each of the hanging beams 1, 1 is provided with a large number of hanging hooks 4 projecting from the lower surface thereof, and each of these hanging hooks 4 can be freely pivoted in the horizontal direction.
It is configured to be rotated by electric rotating cylinders 5, 5. Figure 4 ~ about its configuration
To explain in detail with reference to FIG. 6, each of the hanging hooks 4 is vertically provided with a shaft portion 4a passing through the hanging beam 1, and is slidable in the vertical direction, and is secured downwardly by a nut 6 at the upper end. It is prevented from falling out. An arm 7 is fixed to the shaft portion 4a of each hanging hook 4, and these arms 7 are rotatably connected to a connecting bar 8 provided for each hanging beam 1 with a pin. Therefore, by moving the connecting bar 8 in the directions of arrows A and B as shown in FIGS. 4 and 5, the arm 7 is rotated in the directions of arrows C and D, and the hanging hook 4 is rotated. The electric cylinder 5 as the turning mechanism is connected to the hanging beam 1
It is attached to the top surface of the unit so that it can rotate slightly in the horizontal direction.
The rod tip metal fitting 5a is loosely fitted into the vertical rod 9a of the connecting member 9 provided on the upper surface of the connecting bar 8,
It is designed to cope with the vertical movement of the connecting bar 8 in conjunction with the vertical movement of the hanging hook 4.

Note that the suspension beams 1, 1 are connected to electric cylinders 2, 2.
The mutual spacing is adjusted by the hanging hook 4.
The hanging device of this embodiment is provided with a limit switch (not shown) in order to control both operations. With this limit switch, the distance between the hanging beams 1 and 1 can be accurately adjusted to the hooking width L of the anode A and the hooking width L of the cathode K. hanging beam 1
The suspension beam 1 is retracted to a position along the direction perpendicular to the suspension beam 1, and is moved to a position rotated by 90 degrees from that position during the hanging operation, that is, a position along the longitudinal direction of the suspension beam 1.

Next, with reference to FIGS. 7 to 10, a case will be described in which an anode and a cathode are actually hung using the hanging apparatus having the above structure.

First, when lifting the anode, in this case, the distance between the hanging beams 1, 1 suspended by an overhead crane etc. is adjusted to the dimensions for the anode by the electric cylinders 2, 2, In this state, the hanging beams 1 and 1 are lowered, and the hanging hook 4 is placed in the space next to the anode A as shown in FIG.
is inserted, and the lowering operation of the hanging beams 1, 1 is stopped at an appropriate height. At this time, the hook portion 4b of the hanging hook 4 faces in a direction perpendicular to the longitudinal direction of the hanging beams 1,1. Next, the electric turning cylinders 5, 5 are operated to move the connecting bar 8 in the direction of arrow A in FIG. 4, and the hanging hook 4 is moved as shown in FIG.
Swirl and place under the ear of anode A.
Then, in this state, the suspension beams 1, 1 are raised to lift a large number of anodes A at the same time. In addition, in the device of this embodiment, the hanging hook 4 is designed to be able to slide upward, so even if the hanging hook 4 collides with the upper end of the anode A during the above operation, the hanging hook 4 will not move upward. Accidents caused by running away and bending the hanging hook 4 are prevented.

In addition, when lowering the lifted anode A, the hanging beams 1, 1 are lowered, the anode A suspended from the hanging hook 4 is lowered to a predetermined position, and then the hanging hook 4 is rotated in the opposite direction. Then, the suspension beams 1, 1 are raised and evacuated.

Next, regarding the hanging operation of the cathode K,
In this case, as shown in FIGS. 9 and 10, the explanation is omitted since it is substantially the same as the case of the anode except that the interval between the hanging beams 1 and 1 is adjusted to the dimensions for the cathode.

As described above, according to the hanging device described above, it is possible to hang the bipolar plates by simply adjusting the spacing between the hanging beams by operating the cylinder.

In addition, in this invention, the mechanism for adjusting the interval between the hanging beams and the rotating mechanism for the hanging hook are not limited to those of the above-mentioned embodiments.

As explained above, this invention has a structure in which the distance between a pair of parallel hanging beams can be adjusted by an adjustment mechanism, and a number of hanging hooks that can be rotated by a turning mechanism are provided on the lower surface of the hanging beam. It can also be used for hanging a plurality of electrode plates with different hook hanging widths, so there is no need to prepare a dedicated hanging device for each electrode plate, and equipment costs can be reduced. Further, since a suspension beam interval adjustment mechanism and a suspension hook rotation mechanism are provided as operating mechanisms for performing each operation, the hanging operation can be performed by remote control, resulting in labor savings.
