Description

  The present invention relates to a casting anode removal apparatus and a casting anode removal method. More specifically, the present invention relates to a casting anode that grips a casting anode formed by a mold and appropriately rejects a defective anode and sends a good anode to the next process. The present invention relates to a take-out device and a casting anode take-out method.

  In dry copper smelting, purified crude copper with a purity of about 99.5% obtained by oxidizing and reducing crude copper in a refining furnace can be cast into plate-like crude copper called “anode” for further electrolytic purification. Has been done. The casting of the anode is generally performed as follows. First, the molten metal refined in the refining furnace is temporarily stored in a pan through a tub, and then poured into a pan having a measuring function by a load cell. Then, a plurality of molds arranged in the circumferential direction on the turntable are sequentially cast from the measuring pot in a certain weight (about 350 kg or about 500 kg).

  The molten metal cast into the mold is gradually cooled and solidified by a water cooling part while rotating. The solidified molten metal is taken out from the mold as an anode and sent to the electrolytic purification process. Here, when abnormalities such as bending or distortion are observed in the anode after the cooling process, operational problems such as causing a short circuit in the electrolytic refining process and uneven growth of electrolytic copper May be caused. Therefore, such a defective anode is removed by an exclusion device.

  As a conventional apparatus for removing a defective anode, for example, a device using a jib crane, an articulated robot, or the like, or those shown in Patent Documents 1-4 are known.

The water cooling section 5 cools the anode A by spraying cooling water from a plurality of cooling water spray nozzles (not shown) provided in a cooling water pipe 5a disposed inside the hood via a cooling water supply pipe 5b. I do. However, if the anode A is cooled too rapidly, it will solidify before sufficient degassing, and the thinned copper solidified will cover the anode surface with spots, which will adversely affect the electrolysis process. Therefore, it is preferable to perform the cooling in the water cooling unit 5 gradually.

An anode take-out device 10 is arranged at a position on the rear side of the water cooling unit 5 when viewed from the traveling direction of the mold 3. The anode take-out device 10 is located above the turntable 2 and is arranged to extend in the radial direction of the turntable 2, a moving carriage 20 that reciprocates on the rail 13, and an attachment to the moving carriage 20.

  The frame 12 is provided with a work table 17 for an operator who determines whether the anode A is good or bad along the longitudinal direction thereof. The work table 17 is provided with a control panel (not shown) including an exclusion switch for removing the anode A when the anode A sent to the sorting table 40 by the gripping device 30 described later is defective. As a result, when the anode A sent to the sorting table 40 is defective, the operator can remove the anode A by pressing an exclusion switch (not shown).

  Wheels 21 are respectively attached to the left and right of the movable carriage 20, and a gripping device 30 is mounted on a frame formed in a tower shape. The gripping device 30 has two arm portions 31 and 31 for gripping both side portions of the anode A, and the arm portions 31 and 31 can be moved in the vertical direction by a hydraulic cylinder 35 attached to the movable carriage 20. It is said that. On the distal end side of the arm portions 31, 31 are provided gripping portions 33, 33 for gripping the trunk portion which is the side surface of the anode A.

The molten metal is poured into the recess 3a. Then, the mold 3 in which a predetermined amount of molten metal is cast is carried to the water cooling section 5 by the rotation of the turntable 2 and cooled, and the anode A is molded (step S1).

  Then, the anode A in the mold 3 which has been cooled and solidified by the rotation of the turntable 2 is carried to the lower position of the anode take-out device 10 until the anode A is pushed down the mold 3 by the push-up bar 3c. Is pushed up from the mold 3 and is peeled off from the mold 3 to take an oblique posture. At the same time, the movable carriage 20 of the anode take-out device 10 moves to the upper side of the anode A, and the arm portions 31 and 31 of the gripping device 30 are pushed down by the hydraulic cylinder 35. Then, the arm portions 31 and 31 face the slanted anode A and grip the body portions on both sides of the anode A by the grip portions 33 and 33 from the orthogonal direction (step S2). The gripping device 30 that grips the anode A is lifted upward by the hydraulic cylinder 35 and moves the movable carriage 20 to convey the gripped anode A to the sorting table 40 provided in the middle of the rail 13. (Step S3).

The anode A transported onto the sorting table 40 is judged whether it is good or bad by an operator on the work table 17 (step S4). If the anode A is defective, the operator presses an exclusion switch (not shown) to rotate the rotating shaft 43 of the sorting table 40 and tilt the receiving table 41, so that the defective anode A is slid down and sorted. Exclude from the base 40 (step S5). The rejected defective anode A is reused as a cooling material. On the other hand, when the anode A is good, and the turntable 2 side is conveyed to the cooling tank 50 disposed on the terminal end side of the opposite side of the rail 13, and transfers the chain conveyor 53 of the cooling tank 50. The transferred anode A is cooled (step S6) in the cooling tank 50 in which the cooling water is stored, and then sent to the next electrolytic purification process. Then, the mold 3 after the anode A is taken out by the anode take-out device 10 is further moved by the rotation of the turntable 2, and the release agent is applied to the recesses 3a by the release agent coating device 9a and the casting suppression agent coating device 9b. Then, the operation returns to the pouring position where the molten metal is poured again, and this operation is repeated sequentially.
