Detailed Description

The present invention is made based on the finding by the inventors of the present application of the following facts and problems:

the chain conveying type stripping machine set in the related technology is provided with 1 set of transverse moving chain device and 1 stripping device, the stripping speed is low, and generally, the stripping speed can only reach within 450 sheets/hour.

A double stripping chain conveying type stripping unit with parallel input is provided with 1 set of transverse moving chain device, 2 stripping devices and 2 input devices arranged in parallel, wherein the 2 stripping devices are arranged on 2 adjacent stations on the transverse moving chain device, the 2 input devices are arranged on 2 adjacent stations on the transverse moving chain device, and the 2 input devices can simultaneously input a cathode plate to the transverse moving chain device. This mode sideslip chain needs 2 stations of single operation, and is consuming time longer, and ordinary chain transport formula is peeled off 1 station of unit single operation, and the speed of peeling off the unit can reach 600 pieces/hour, and because the station on the sideslip chain device is many, its area is bigger.

The robot type stripping unit is generally provided with 2 stripping devices and 2 robot grippers matched with the stripping devices, and the robot grippers are used for inputting or outputting a negative plate from the stripping devices. Because the two robot grippers need to avoid each other when inputting and outputting the cathode plate, and the transportation speed of the robot grippers is limited, the speed of the stripping unit in the form is generally 600 sheets/hour.

Modern smelters are becoming larger and larger, for example for copper electrolysis plants with a size of more than 30 ten thousand tons of cathode copper per year, if the stripping speed is 600 pieces per hour, 2 cathode stripping units are generally needed, which requires more equipment floor space and higher investment, so that the development of a stripping unit with a higher stripping speed is particularly important.

In addition, the first transverse moving conveying device 10 and the second transverse moving conveying device 20 are arranged, and the conveying directions of the first transverse moving conveying device 10 and the second transverse moving conveying device 20 are the same, so that the operation link of the cathode plate can be simplified, the structure of the cathode stripping device 1 is simplified, the cost of the cathode stripping device 1 can be reduced, and the maintenance of the cathode stripping device 1 is facilitated.

Therefore, the cathode stripping device 1 according to the embodiment of the invention has the advantages of high production efficiency, low cost and the like.

A cathode stripping device 1 according to an embodiment of the present invention is described below with reference to the drawings.

In some embodiments of the present invention, as shown in fig. 1, a cathode stripping device 1 according to an embodiment of the present invention includes a first traverse transport device 10, a second traverse transport device 20, a cathode plate input device, a cathode plate output device, a first stripping device 50, and a second stripping device 60.

Specifically, as shown in fig. 1, the cathode stripping device 1 further includes a receiving conveyor 31. The plate receiver conveyor 31 is for receiving the cathode plate. The input transfer device 32 is used to transfer the cathode plates on the plate receiver conveyor 31 to the first traverse transporter 10 and the second traverse transporter 20. Thus, the cathode plate can be transported and transferred by the plate receiving conveyor 31 and the input transfer device 32, respectively, and the transportation of the cathode plate can be realized.

Advantageously, as shown in fig. 1, the cathode stripping device 1 further includes a washing device 33 for washing the cathode plate, the washing device 33 being connected between the plate-receiving conveyor 31 and the input transfer device 32. This allows the cathode plate to be washed to facilitate the stripping operation of the cathode plate.

More specifically, as shown in fig. 1, the cathode stripping device 1 further includes a gang board conveyor 41. The discharge plate conveyor 41 is used to discharge the cathode plate. The output transfer device 42 is used for transferring the cathode plates on the first traverse transporter 10 and the second traverse transporter 20 to the plate discharge transporter 41. Thus, the cathode plate can be transported and transferred by the plate arranging transporter 41 and the output transfer device 42 respectively, and the transportation of the cathode plate is realized.

Alternatively, as shown in FIG. 1, the input transfer device 32 and the output transfer device 42 are both located on the side of the first traverse transport 10 remote from the second traverse transport 20; or the input transfer device 32 and the output transfer device 42 are both located on the side of the second traverse transport device 20 remote from the first traverse transport device 10. Therefore, the feeding and the blanking of the cathode plate can be conveniently carried out, and the centralized treatment of the cathode plate is convenient.

Fig. 1 shows a cathode stripping device 1 according to one specific example of the invention. As shown in fig. 1, the cathode stripping apparatus 1 further includes a waste board detecting device for detecting waste boards on the first traverse transporter 10 and the second traverse transporter 20, and a waste board discharging device for discharging waste boards on the first traverse transporter 10 and the second traverse transporter 20, the waste board detecting device being electrically connected to the waste board discharging device, the waste board discharging device being connected to the first discharging end 12 and the second discharging end 22.

Therefore, the quality of the deposited metal and the quality of the polar plate of the cathode plate can be detected, and if the quality does not reach the standard, the plate is judged to be a waste plate.

More specifically, as shown in fig. 1, the waste sheet output apparatus includes a waste sheet transporter 81 and a waste sheet transfer apparatus 82. The scrap conveyor 81 is used to discharge the scrap. The waste board transfer device 82 is used to transfer the waste boards on the first traverse transporter 10 and the second traverse transporter 20 to the waste board transporter 81. Thus, the cathode plate can be transported and transferred by the waste plate transporter 81 and the waste plate transfer device 82, respectively, and the transportation of the cathode plate can be realized.

Advantageously, as shown in FIG. 1, the scrap panel detection apparatus is disposed between the first traverse transport apparatus 10 and the second traverse transport apparatus 20. Therefore, the first transverse moving conveying device 10 and the second transverse moving conveying device 20 can be conveniently detected by the waste plate detection device, and the structural compactness of the cathode stripping device 1 is improved.

Alternatively, as shown in fig. 1, the waste board discharging device is parallel to the discharging transfer device 42 and is closer to the first discharging end 12 and the second discharging end 22 than the discharging transfer device 42. This makes the structure of the cathode stripping device 1 more reasonable.

This facilitates the detection of the quality of the deposited metal of the cathode plate and the quality of the cathode plate itself.

In one embodiment of the invention, the deposit metal quality detection device 71 is located between the first infeed end 11 of the first traverse transport 10 and the first stripping device 50. This can facilitate the setting of the deposited metal quality detecting device 71.

In another embodiment of the present invention, the deposit metal quality detecting device 71 is located between the second infeed end 21 of the second traverse transport 20 and the second stripping device 60. This can facilitate the setting of the deposited metal quality detecting device 71.

The input double-transfer device takes 2 polar plates out of the plate receiving device at a time and respectively inputs the polar plates into the first transverse moving conveying device and the second transverse moving conveying device, or respectively inputs the polar plates into the first transverse moving conveying device and the input transition device, the input transition device can temporarily store 1 to more than one polar plates, and the input single-transfer device inputs the polar plates into the second transverse moving conveying device from the input transition device.

Specifically, as shown in fig. 3, the output transfer device 42 includes an output dual transfer device 421, an output transition device 422, and an output single transfer device 423, and the output dual transfer device 421, the output transition device 422, and the output single transfer device 423 are respectively arranged in sequence along the plate transportation direction. The output single transfer device takes the polar plates out of the second transverse moving and conveying device and inputs the polar plates into the output transition device; the output double-transfer device outputs the polar plates on the first transverse moving conveying device and the second transverse moving conveying device to the plate arranging device, or outputs the polar plates on the first transverse moving conveying device and the output transition device to the plate arranging device, and the output transition device can temporarily store 1 to a plurality of polar plates.

The operation of the cathode stripping device 1 according to an embodiment of the present invention is described below with reference to fig. 1.
