Description

Technical Field

[0001] The utility model relates to the technical field of prebaked anode cleaning equipment for electrolytic aluminum, in particular to a prebaked anode carbon block centering positioning device. Background Art

[0002] At present, electrolytic aluminum is aluminum obtained by electrolysis. Modern electrolytic aluminum industry production adopts cryolite-alumina molten salt electrolysis. Molten cryolite is the solvent, alumina is the solute, carbonite is the anode, and aluminum liquid is the cathode. After a strong direct current is passed through, an electrochemical reaction is carried out at the two electrodes in the electrolytic cell at 950℃-970℃, that is, electrolysis. The prebaked anode carbon blocks (hereinafter referred to as anode carbon blocks) used in traditional electrolytic aluminum will adhere to a layer of filler on the surface after being fired out of the furnace. This layer of filler needs to be cleaned before it can be delivered to customers for use.

[0003] The conventional cleaning method in the industry now relies on manual cleaning, but the workers face a variety of disadvantages such as dusty working environment, high labor intensity, and harm to human health. In addition, with the annual increase in labor costs and fewer young workers choosing to work on production lines, many companies have begun to consider using mechanical automated cleaning lines to replace manual operations to reduce costs.

[0004] The main reason is that anode carbon blocks are mainly transferred by roller lines during production. However, after being fired, the surface shape of anode carbon blocks will be slightly deformed, and the surface becomes rough and uneven due to the adhesion of fillers. Therefore, when they flow on the roller line, the contact points between the bottom surface and each roller are not fixed and uniform, which makes the position of anode carbon blocks always in dynamic change during the long-distance transportation process. Therefore, it is impossible for them to keep parallel with the direction of movement through their own length direction. Due to this situation, the automatic cleaning of anode carbon blocks is further difficult.

[0005] Therefore, we need to design a prebaked anode carbon block centering device to overcome the above problems. Utility Model Content

[0006] In view of the above-mentioned deficiencies existing in the prior art, the purpose of the utility model is to provide a centering device for prebaked anode carbon blocks, which is used to solve the problem that the surface shape of the existing anode carbon blocks will undergo slight deformation after firing, and the surface becomes rough and uneven due to the adhesion of fillers. Therefore, when the anode carbon blocks flow on the roller line, the contact points between the bottom surface and each roller are not fixed and uniform, so that the position of the anode carbon blocks is always in dynamic change during the transportation process of longer distances, and it is impossible to keep the length direction of the anode carbon blocks parallel to the movement direction.

The lifting mechanism and the centering positioning device are arranged in parallel and opposite positions; a plurality of roller structures are arranged on the roller line, and the anode carbon block is carried on the roller line, and the anode carbon block is located between the lifting mechanism and the centering positioning device to position the anode carbon block.

It is used to ensure that the bearing is installed in place on the workpiece.

[0014] In order to further improve the use convenience of the prebaked anode carbon block centering positioning device, the solution adopted by the utility model is that the number of the clamping rods is two.

[0015] In order to further improve the use convenience of the prebaked anode carbon block centering positioning device, the solution adopted by the utility model is: the hydraulic cylinder adopts one of the model parameters of QG, S, SC, SS and YB single-rod hydraulic cylinders.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 2The utility model is a pre-baked anode carbon block centering positioning device, which uses a hydraulic cylinder 37 as a power source and is designed based on a gear rack mechanism 33 as a basic transmission structure, including a lifting mechanism 2, a centering positioning device 3 and a roller line 4, which is connected to the upper part, and is characterized in that: the lifting mechanism 2 is arranged on one side along the length direction of the roller line 4, and the centering positioning device 3 is arranged on the other side along the length direction of the roller line 4. The lifting mechanism 2 and the centering positioning device 3 are arranged in parallel and opposite positions; an anode carbon block 1 is supported on the roller line 4, and the anode carbon block 1 is located between the lifting mechanism 2 and the centering positioning device 3, so as to position and correct the anode carbon block 1.

[0023] When the utility model is used, the anode carbon block 1 flows along the conveyor line to the automatic cleaning station of the robot and is adjacent to the centering positioning device 2. The hydraulic cylinder 37 of the centering positioning device 3 starts to work, and its reciprocating action drives the clamping rod 36 to clamp in the middle of the centering positioning device 3. When the anode carbon block 1 is centered in place, the in-place inspection mechanism 35 on the clamping rod 36 is triggered, the clamping rod 36 releases the workpiece, and the origin sensor 32 senses the moving position of the clamping rod 36 to detect whether the clamping rod 36 has returned to the starting position. When the anode carbon block triggers the photoelectric sensor on the roller line 4, the anode carbon block has reached the currently required position, so the roller line 4 stops.

The gear rack mechanism 33 is connected to the linear bearing sliding structure 34 through the clamping rod 36, and the clamping rod 36 is also connected to the hydraulic cylinder 37. The hydraulic cylinder 37 pushes the clamping rod 36 on one side, and the clamping rod 36 on the other side simultaneously moves to clamp in the middle of the centering positioning device 3, and the in-place inspection mechanism 35 is fixed on the middle of the clamping rod 36. The number of the clamping rods 36 is two. When the clamping rods 36 on both sides touch the anode carbon block 1 at the same time and center it, the in-position inspection mechanism 35 is triggered, and then the centering positioning device 3 is released, and the clamping rods 36 return to the initial position.

[0026] Furthermore, the base 31 is configured as a square tube welding frame, and the square tube welding frame is composed of four square tubes connected in sequence, and has good stability.

[0027] Furthermore, the origin sensor 32 adopts a sensor with a model parameter of HPS-LCB2 to sense the azimuth distance.

[0031] Furthermore, the hydraulic cylinder 37 adopts one of the model parameters of QG, S, SC, SS and YB single-rod hydraulic cylinders.
