Description

Technical Field

[0001] The present invention relates to the technical field of non-ferrous metal electrolysis processes, and particularly to a metal electrolysis polar plate combined lifting system and method. Background Art

[0002] The electrolysis process is one of the main ways to obtain high-purity non-ferrous metal materials at present. The electrolytic cell is the main equipment of the electrolysis process. The electrolytic cell is a rectangular tank, in which anode plates and cathode plates are successively hung. During operation, each anode plate and cathode plate in the electrolytic cell work on both sides (except for the plates at both ends of the electrolytic cell), that is, both sides of the anode plate dissolve simultaneously, and both sides of the cathode plate precipitate simultaneously.

[0003] The invention patent with the application number CN201380021356.7 discloses a transfer device for transferring, lifting, and lowering anode plates and cathode plates, including a plurality of paired components. Each paired component is arranged to be paired with and cooperate with an anode hook, and each paired component has a certain structure and size to be inserted into the gap between the anode plate and the cathode plate existing in the electrolytic cell at the second side of the anode plate to be grabbed and lifted, so that the lug of the anode plate to be grabbed and lifted is located between the pair of anode hooks and the paired component, and can be used for double lifting of anodes without inner ears.

[0004] However, at present, copper electrolysis traveling cranes have not been able to achieve automatic double lifting of anodes without inner ears with a small spacing (100 - 105 mm). Because for the double lifting of anodes without inner ears with a small spacing, due to the small spacing between the anode plate and the cathode plate, it is difficult for the paired components to be inserted into the gap between the anode plate and the cathode plate existing in the electrolytic cell. Summary of the Invention

[0005] Based on the above description, the present invention provides a metal electrolysis polar plate combined lifting system and method. When the cathode plate is lifted to a certain height, the cathode translation mechanism is used to push the cathode hanger to generate a certain horizontal displacement, thereby increasing the spacing between one side of the cathode plate and the anode plate, enabling the anode hook to be inserted into the gap between the anode plate and the cathode plate existing in the electrolytic cell, and realizing automatic double lifting of anodes without inner ears.

By providing independent main winding drum groups and auxiliary winding drum groups, when the auxiliary winding drum group rotates, the auxiliary winding hook can move up and down relative to the main winding hook. Therefore, when the main winding drum group does not rotate and the auxiliary winding drum group rotates, the auxiliary winding hook can be lifted alone, thereby realizing the separate lifting of the cathode plate; when the main winding drum group rotates and the auxiliary winding drum group does not rotate, the main winding hook and the auxiliary winding hook can be lifted synchronously to lift the cathode plate and the anode plate from the electrolytic cell together. In addition, by eccentrically arranging the auxiliary winding drum on the auxiliary winding drum group, when the auxiliary winding drum group rotates by a certain angle, a relative displacement in the horizontal direction of the auxiliary winding hook relative to the main winding hook can be realized; when hoisting the cathode plate and the anode plate, the cathode plate can be offset by a certain distance, leaving enough space between the cathode plate and the anode plate to facilitate hooking and lifting the anode plate.

[0022] A metal electrolytic polar plate combination lifting system includes a lifting mechanism, a fixed frame 4, a guiding bracket 5, a cathode sling 8 and an anode sling 7.

[0023] Among them, the lifting mechanism includes a trolley 1, a main lifting device 2 and a secondary lifting device 3. The main lifting device 2 is used to drive the anode hanger 71 and the cathode hanger 81 to move up and down simultaneously. The secondary lifting device 3 is used to drive the cathode hanger 81 to move up and down alone, and is used to drive the cathode hanger to move back and forth relative to the anode hanger 71.

[0024] Specifically, the main lifting device 2 includes a main winding drum group 21, a main winding steel wire rope 22, a main winding movable pulley 23 and a main driving assembly. The main winding drum group 21 is rotatably installed on the trolley 1. One end of the main winding steel wire rope 22 is wound around the main winding drum group 21. The main winding steel wire rope 22 bypasses the main winding movable pulley 23, and the other end of the main winding steel wire rope 22 is fixed on the trolley 1. The main driving assembly is used to drive the main winding drum group 21 to rotate.

[0025] In this embodiment, the main lifting device 2 includes two main winding drum groups 21 arranged in parallel. Each main winding drum group 21 is connected with two main winding movable pulleys 23. The four main winding movable pulleys 23 are arranged at the same height, so as to lift through four lifting points and realize the stable lifting of the anode sling 7.

[0026] The main driving assembly includes a main winding motor 24 and a speed reducer 25. The main winding motor 24 is connected to the two main winding drum groups 21 through the speed reducer 25. Thus, one main winding motor 24 drives the two main winding drum groups 21 to rotate synchronously, ensuring the synchronous lifting of the four main winding movable pulleys 23.

[0027] The auxiliary hoisting device 3 includes an auxiliary winding drum set 31, an auxiliary winding steel wire rope 32, an auxiliary winding movable pulley 33, and an auxiliary drive assembly. The auxiliary winding drum set 31 is rotatably installed on the trolley 1. One end of the auxiliary winding steel wire rope 32 is wound around the auxiliary winding drum set 31. The auxiliary winding steel wire rope 32 bypasses the auxiliary winding movable pulley 33, and the other end of the auxiliary winding steel wire rope 32 is wound around the main winding drum set 21. The auxiliary drive assembly is used to drive the auxiliary winding drum set 31 to rotate.

[0028] In this embodiment, the auxiliary hoisting device 3 includes two auxiliary winding drum sets 31 corresponding to the two main winding drum sets 21 one by one. Each auxiliary winding drum set 31 is respectively connected to the corresponding main winding drum set 21 through two auxiliary winding steel wire ropes 32. An auxiliary winding movable pulley 33 is arranged on each auxiliary winding steel wire rope 32. The four auxiliary winding movable pulleys 33 are arranged at the same height, so as to hoist through four lifting points and realize the stable hoisting of the cathode sling 8.

[0029] The auxiliary drive assembly includes two auxiliary winding motors 34. The two auxiliary winding motors 34 are respectively connected to the two auxiliary winding drum sets 31. The two auxiliary winding motors 34 are kept synchronized through the control system, so as to ensure the synchronous lifting and lowering of the four auxiliary winding movable pulleys 33.

[0030] Furthermore, the axes of the main winding drum set 21 and the auxiliary winding drum set 31 are parallel, and the auxiliary winding drum set 31 includes an auxiliary winding rotating shaft 311 and an auxiliary winding drum 312. The auxiliary winding drum 312 is installed on the auxiliary winding rotating shaft 311 in parallel and eccentrically. The auxiliary drive assembly is used to drive the auxiliary winding drum set 31 to rotate around the axis of the auxiliary winding rotating shaft 311.

[0031] In this embodiment, by setting the independent main winding drum set 21 and auxiliary winding drum set 31, when the auxiliary winding drum set 31 rotates, the auxiliary winding movable pulley 33 can produce relative lifting and lowering relative to the main winding movable pulley 23. Therefore, when the main winding drum set 21 does not rotate and the auxiliary winding drum set 31 rotates, the auxiliary winding movable pulley 33 can hoist alone, so as to realize the separate hoisting of the cathode plate 93. When the main winding drum set 21 rotates and the auxiliary winding drum set 31 does not rotate, the main winding movable pulley 23 and the auxiliary winding movable pulley 33 can be kept lifting synchronously to realize lifting the cathode plate 93 and the anode plate 92 together out of the electrolytic cell 91.

[0032] In addition, in this embodiment, by eccentrically arranging the auxiliary winding drum 312 on the auxiliary winding drum set 31, after the auxiliary winding drum set 31 rotates a certain angle, a relative displacement in the horizontal direction can be realized between the auxiliary winding movable pulley 33 and the main winding movable pulley 23. When hoisting the cathode plate 93 and the anode plate 92, the cathode plate 93 can be offset by a certain distance, so as to leave enough space between the cathode plate 93 and the anode plate 92 to facilitate hooking and lifting the anode plate 92.

[0033] The anode lifting device 7 includes an anode lifting frame 71, an anode driving mechanism, and a plurality of anode hooks 72. The anode hooks 72 are respectively arranged at the bottoms of the left and right sides of the anode lifting frame 71 in a front-back arrangement, and the anode driving mechanism is used to drive the anode hooks 72 to be hooked on the anode plate 92. An anode support 75 is provided at the top of the anode lifting frame 71, and the main winding pulley is rotatably connected to the anode support 75.

The anode electric cylinder 73 is installed on the anode lifting frame 71, and the anode electric cylinder 73 is used to drive the connecting rod 74 to move back and forth, thereby driving the anode hooks 72 to rotate simultaneously.

[0035] A storage cavity is provided on the anode lifting frame 71, and the cathode lifting frame 81 is horizontally and vertically movably arranged in the storage cavity. The cathode lifting device 8 includes a cathode lifting frame 81, a cathode driving mechanism, and a plurality of cathode hooks 82.

[0042] In this embodiment, by providing the front guide block 812 and the rear guide block 814, when the cathode plate 93 needs to be lifted alone, the cathode hanger 81 descends relative to the anode hanger 71, and the front guide block 812 and the rear guide block 814 guide and position the cathode hanger 81, so as to ensure that when the longitudinal relative positions of the anode and cathode hangers 71 change, the transverse relative positions of the anode and cathode hangers 71 change synchronously.

[0043] The fixed frame 4 is installed at the bottom of the trolley 1. The fixed frame 4 is used to install the cab, and an acid receiving tray 41 is provided at the bottom of the fixed frame 4. The guide frame is arranged below the fixed frame 4, and when the guide bracket 5 moves to the uppermost position of the stroke, it is located within the fixed frame 4.

[0044] On the front and rear top sides of the guiding support 5, upper positioning cones 55 are respectively arranged. In the front and rear parts within the fixed frame 4, intermediate anti-sway devices 6 are respectively arranged. The intermediate anti-sway device 6 includes a fixed support 61 and a movable square pipe 62. In this embodiment, the top of the fixed support 61 is fixed to the bottom of the trolley 1.

[0045] On the front and rear top sides of the electrolytic cell 91, lower positioning cones 911 are arranged. On the front and rear bottom sides of the guiding support 5, lower positioning holes 56 matching the lower positioning cones 911 are arranged.

[0047] In addition, on the left and right bottom sides of the bottom of the guiding support 5, anti-sway combs 53 are respectively arranged. The distance between the anti-sway combs 53 on both sides matches the width of the cathode plate 93. The anti-sway combs 53 on both sides are rotatably connected to the guiding support 5. On the two sides of the guiding support 5, electric push rods 54 for driving the anti-sway combs 53 on the same side to rotate are respectively arranged. The anti-sway combs 53 are used to make the side of the cathode plate 93 be inserted into the middle of the anti-sway combs 53 during the process of hoisting the cathode plate 93, so as to prevent the cathode plate 93 from swinging too much and facilitate the cathode plate 93 to be safely and reliably inserted into the middle of the anode plate 92.

[0048] The method for hoisting the cathode plate 93 and the anode plate 92 of the hoisting system in this embodiment includes the following steps: (1) The main hoisting device 2 drives the cathode hanging bracket 81 and the anode hanging bracket 71 to descend simultaneously, so that the cathode hanging bracket 81 and the anode hanging bracket 71 move to be close to the electrolytic cell 91 simultaneously. The guiding support 5 descends together with the anode hanging bracket 71. The lower positioning cone 911 at the top of the electrolytic cell 91 is inserted into the lower positioning hole 56 at the bottom of the guiding support 5, realizing the positioning of the guiding support 5, and realizing the positioning of the anode hanging bracket 71 in the horizontal direction through the guiding support 5.

[0049] (2) The auxiliary hoisting device 3 drives the cathode sling 8 to descend further. When the cathode sling 8 reaches the set position, the cathode driving mechanism drives the cathode hook 82 to pass through the cathode hoisting hole, as Figure 20 shown, so that the cathode hook 82 hangs on the cathode plate 93.

[0050] (3) As Figure 21As shown, the auxiliary hoisting device 3 drives the cathode spreader 8 to hoist upward, and at the same time drives the cathode spreader 8 to offset a certain distance forward and backward relative to the anode hanger 71.

[0051] (4) The main hoisting device 2 drives the cathode spreader 8 and the anode spreader 7 to descend simultaneously, so that the anode hook 72 passes through the gap between the cathode plate 93 and the anode plate 92. When the anode spreader 7 reaches the set position, as Figure 22 shown, the anode drive mechanism drives the anode hook 72 to hook the outer ear of the anode plate 92.

[0052] (5) The main hoisting device 2 drives the cathode spreader 8 and the anode spreader 7 to hoist simultaneously, so that the cathode plate 93 and the anode plate 92 are lifted away from the electrolytic cell 91 together. At this time, the guide wheel 76 abuts against the bottom of the limit plate 52, so that the anode spreader 7 drives the guide bracket 5 to move upward together. After the guide bracket 5 enters the fixed frame 4, the upper positioning cone 55 is inserted into the upper positioning hole 621 at the bottom of the movable square tube 62, so that the guide bracket 5 rises together with the movable square tube 62, which can avoid the shaking of the guide bracket 5, the anode spreader 7 and the cathode spreader 8.

[0053] In this embodiment, when the cathode plate 93 is lifted to a certain height, the cathode translation mechanism is used to push the cathode hanger 81 to generate a certain horizontal displacement, thereby increasing the distance between one side of the cathode plate 93 and the anode plate 92, so that the anode hook 72 can be inserted between the anode plate 92 and the cathode plate 93 existing in the electrolytic cell 91, realizing the automatic double lifting of the anode without inner ear.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
