Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis production, in particular to an automatic unloading and lifting tray device for cleaning residual anodes. Background Art

[0002] During the aluminum electrolysis production process, as the anode carbon blocks are consumed, they need to be replaced, and the materials on the surface of the residual anodes need to be cleaned for recycling, classification and reuse. During the material cleaning process, the height of the residual anodes needs to be lifted to the height required by the cleaning equipment. Using conventional pallets will cause a large amount of material to accumulate on the pallet, causing the residual anodes to be lifted too high or requiring operators to clean them at any time to ensure the quality of operation. If a pallet plus a flip tray is used, as the number of components increases, the internal space of the pallet is limited, the operability is low, the failure rate and the cost of inspection and maintenance increase significantly, and the inspection and maintenance process seriously affects the orderly production.

[0003] For example, the patent with publication number CN207698805U proposes a lifting and turning material tray for cleaning residual anodes of aluminum electrolysis. The overall lifting and lowering of the upper frame and the tray body are realized by a lifting mechanism, and then the tray body is changed from a horizontal position to an inclined position around the hinge by extending the piston rod of the first power cylinder, so that the material on the tray body is dumped out. When combined with the cleaning device for residual anodes of aluminum electrolysis, the residual anodes can be kept stably lifted and lowered during the lifting process, which is convenient for other cleaning mechanisms to clean, effectively improving work efficiency, and dumping the cleaned materials out. The structure is simple and the operation is reliable. However, the device first lifts the tray through the lifting mechanism, and then dumps the accumulated materials by turning the tray over. In actual production, when there is a lot of accumulated materials, the lifting and turning over are easy to reach a predetermined height, affecting the residual anodes. Utility Model Content

[0004] The utility model aims to provide an automatic unloading lifting tray device for cleaning scrap anodes, so as to solve the technical problem that when the existing scrap anode lifting tray has a lot of material accumulation, the lifted material is easy to affect the scrap anodes.

[0005] The embodiments of the present invention are implemented by the following technical solutions:

[0006] A device for automatically unloading and lifting a tray for cleaning anode residues comprises a lifting mechanism for lifting the tray and a tray arranged on the lifting mechanism. The tray is arranged in a table shape, and the size of the hollow top surface structure is smaller than the size of the anode residues. The tray is provided with a slope for automatically dropping accumulated materials.

[0007] Preferably, the lifting mechanism includes several groups of outer scissor frames and inner scissor frames which are hinged to each other through a first rotating shaft at the middle part, one end of the outer scissor frame and the inner scissor frame are hinged to the base, and the other ends are respectively hinged to the first slider and the second slider; the first slider and the second slider are slidably connected to the base.

[0008] Preferably, the base is provided with a first sliding groove and a second sliding groove for slidingly connecting the first slider and the second slider respectively, and is also provided with a first hinge part and a second hinge part for hingedly connecting the outer scissors frame and the inner scissors frame respectively.

[0009] Preferably, it also includes a telescopic device for driving the lifting mechanism to lift, one end of the telescopic device is hinged to the base, and the other end is hinged to the movable roller, and the inner scissor frame is provided with a third sliding groove for slidingly connecting the movable roller.

[0010] Preferably, the base is provided with an articulated frame for hingedly connecting the telescopic device.

[0011] Preferably, several groups of the outer scissor frame sliding ends are provided with a first connecting rod for mutual linkage, and several groups of the inner scissor frame sliding ends are provided with a second connecting rod for mutual linkage; several groups of the outer scissor frame hinged end shafts are connected to a second rotating shaft for mutual linkage, and several groups of the inner scissor frame hinged end shafts are connected to a third rotating shaft for mutual linkage.

[0012] Preferably, the tray is configured to be in the shape of a quadrangular pyramid, and the slopes are provided on both sides of the tray and at the exit.

[0013] By adopting this technical solution, the platform structure of the tray can be used in conjunction with the lifting process to automatically cause the accumulated materials to fall off the slope during the rising process, without forming an accumulation. Even if an accumulation is formed, the structural size of the accumulation is smaller than the structural size of the residual anode, so that the residual anode will not be affected.

[0014] The lifting structure of the device of the present application uses a group of telescopic devices to telescopically control the sliding of the movable roller in the third slide groove to be suitable for various angles. When the movable pulley slides to one end of the third slide groove, the lifting and lowering of the first rotating shaft can be controlled through the third slide groove, thereby controlling the hinged rotation of the outer scissor frame of the inner scissors frame to complete the lifting and lowering of the tray. The control is simple and effective.

[0015] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0016] 1. The utility model uses the platform structure of the tray to cooperate with the lifting process, so that the accumulated materials will automatically fall off from the slope during the rising process, and will not form accumulation;

[0017] 2. Even if the utility model forms an accumulation, the structural size of the accumulation is smaller than the structural size of the residual anode, so the residual anode will not be affected. BRIEF DESCRIPTION OF THE DRAWINGS
