[0002] In the current aluminum electrolysis industry, the surface of the spent anode is prone to form a hard shell of electrolyte, resulting in the inability to recycle the spent anode. Various spent anode electrolyte cleaning equipment is required to clean the hard shell of electrolyte on the steel claws. Commonly used electrolyte cleaning equipment includes ferrophosphorus ring pressing and removing machines, chain flinging cleaning machines, hydraulic crushers, shovel crushers, etc. During operation, a suspension chain or a walking trolley machine, etc., sends the guide rod group in the waiting position to the stop position of the cleaning equipment.

Specific embodiments

[0040] In order to make the technical objectives, technical solutions, and beneficial effects of the present invention clearer, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] A specific embodiment of the five - hammer crushing electrolyte cleaning machine, as Figures 1 to 17 shown, includes an electrolyte cleaning machine main body. The electrolyte cleaning machine main body includes a left - hand assembly 1100 and a right - hand assembly 1200 of the cleaning machine that are spaced apart left and right. A guide rod lifting device 2000 is provided on the right - hand assembly 1200 of the cleaning machine. Both the left - hand assembly 1100 and the right - hand assembly 1200 of the cleaning machine include a cleaning machine base and a hydraulic breaker assembly 1120 that is movably arranged left and right on the cleaning machine base 1110. There are a total of five hydraulic breaker assemblies 1120, and the hydraulic breaker assemblies on the cleaning machine assembly are arranged in a staggered manner in the front - to - back direction.

[0042] The guide rod lifting device 2000 includes a lifting device base frame 2100 and a lifting device top plate 2200. The lifting device base frame 2100 includes two base frame seat plates 2110 arranged in parallel and spaced relation on the left and right. The two base frame seat plates 2110 are detachably mounted on a base assembled 1200 on the right side of the cleaning machine. The lifting device top plate 2200 is a rectangular structure. The lifting device top plate 2200 is arranged horizontally. A parallel four-bar linkage mechanism is arranged between the two base frame seat plates 2110 for driving the lifting device top plate 2200 to move horizontally.

[0043] The parallel four-bar linkage mechanism includes four triangular chain plates 3100, which are arranged at rectangular intervals. The two front triangular chain plates 3100 are respectively hinged to the base frame seat plate 2110 through a pin shaft 3110, and the two rear triangular chain plates 3100 are hinged to a connecting shaft 3120 horizontally arranged between the two base frame seat plates 2110. One end of each triangular chain plate 3100 is hinged to the top plate 2200 of the lifting device, and the other end is connected by a pull rod 3200.

[0044] The guide rod lifting device 2000 also includes a lifting device driving structure 3300 for applying a driving force to the parallel four-bar linkage. The lifting device driving structure includes a support gantry 3310 arranged on a base assembled 1200 on the right side of the cleaning machine and a lifting seat 3320 arranged on the lifting device top plate 2200. The support gantry 3310 includes a support gantry lower part 3311 arranged across the lifting device base frame 2100 and a support gantry upper part 3312 arranged on the support gantry lower part 3311. The width of the support gantry lower part 3311 is greater than the width of the support gantry upper part 3312, and is used for support. The height of the support gantry upper part 3312 is greater than the height of the support gantry lower part 3311, and is used for lifting.

[0045] The lifting seat 3320 is an L-shaped structure, one end of which is connected to the top plate 2200 of the lifting device, and the other end horizontally extends into the upper part of the support mast 3312. An inverted lifting cylinder 3400 is provided on the crossbeam of the upper part of the support mast 3312, and the cylinder body of the lifting cylinder 3400 is hinged on the upper part of the support mast 3312. The output end of the lifting cylinder 3400 is connected to the lifting seat 3320 through a steel chain 3500.

[0046] The guide rod lifting device 2000 also includes a guide rod clamping structure 3600 disposed on the lifting device top plate 2200 for clamping the guide rod to drive the guide rod to move. The guide rod clamping structure 3600 adopts an existing steel claw clamping head device. The guide rod lifting device 2000 also includes an in-position sensor for sending a signal when the lifting device top plate 2200 moves to a position (that is, the steel claw crossbeams of the guide rod group are at the same reference height). The in-position sensor in this embodiment is a laser switch 3700 disposed on the left assembly 1100 of the cleaning machine.

[0047] The guide bar lifting device 2000 includes a limit structure 3800 for restricting the movement range of the top plate 2200 of the lifting device. The limit structure 3800 includes a fixedly arranged limit rod 3810 and a limit sleeve 3820 arranged on the top plate 2200 of the lifting device. The limit sleeve 3820 is in a rectangular frame structure. The inner hole of the limit sleeve 3820 through which the limit rod 3810 passes has an activity interval for the top plate 2200 of the lifting device to move. A vertically arranged screw rod 3830 is provided at the top of the limit sleeve 3820. The end of the screw rod 3830 is screwed into the limit sleeve 3820 to block the limit rod 3810. By adjusting the depth of the screw rod 3830 screwed into the limit sleeve 3820, the activity range of the top plate 2200 of the lifting device is adjusted.

[0048] During operation, the walking beam pusher machine pushes the guide bar group at the waiting position to the stop position of the five-hammer crushing electrolyte cleaning machine. After reaching the position, the guide bar clamping structure 3600 of the guide bar lifting device 2000 clamps the guide bar. Under the action of the lifting device driving structure 3300, the top plate 2200 of the lifting device drives the guide bar group to lift and lower a certain height, so that the steel claw cross beam is at the same reference height.

[0049] After reaching the position, the guide bar positioning device 1130 on the left side of the cleaning machine assembly 1100 positions the guide bar, and then the residual anode pre-tightening mechanism positions the residual anode. After the positioning is completed, the hydraulic walking platform drives the five hydraulic crushing hammer assemblies 1120 to start working, vibrating and loosening the electrolyte on the residual anode group. Compared with the prior art, the problem that due to the length error of the guide bar, the steel claw cross beam cannot reach the same reference height position when the guide bar group is at the stop position of the cleaning equipment, resulting in the cleaning effect not being guaranteed, is solved.

[0050] In other embodiments of the five-hammer crushing electrolyte cleaning machine, a lifting device driving structure in other structural forms can also be adopted. For example, a jacking hydraulic cylinder for jacking the top plate of the lifting device is arranged below the top plate of the lifting device, and the position of the top plate of the lifting device is adjusted by controlling the lifting and lowering of the piston rod of the jacking hydraulic cylinder; or a driving structure that inputs torque to the connecting shaft of a parallelogram four-bar structure is adopted.

[0051] In the embodiment of the guide bar lifting device for the electrolyte cleaning machine of the present invention, the structure of the guide bar lifting device for the electrolyte cleaning machine is the same as that of the guide bar lifting device in any of the above embodiments of the five-hammer crushing electrolyte cleaning machine, so it will not be repeated here.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Any equivalent replacement of the present invention and any modification or partial replacement without departing from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
