Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to a device for dry-dipping graphite in guide rod claws. Background Technology
[0002] The conventional guide rod claw graphite device is a crucial piece of equipment in anode assembly production. Before assembling with the anode carbon block, the anode guide rod claw must be dipped in graphite to enhance the conductivity between the steel claw and the carbon block, and also facilitates the re-detachment of the phosphorus iron ring from the guide rod claw for reuse. The original graphite coating process used a wet dipping method with a mixture of graphite and kerosene to achieve graphite coating, resulting in high consumption of graphite powder and kerosene. To save costs, a wet dipping method using a mixture of water and graphite was adopted, but the mixing effect of graphite and water was extremely poor, leading to poor graphite coating. Furthermore, both processes require drying in a gas-fired drying oven. The drying process consumes a large amount of natural gas, and incomplete evaporation of moisture can easily cause splashing of the cast phosphorus iron, posing a safety hazard. Simultaneously, the poor graphite coating effect results in a high iron-carbon voltage drop during electrolysis of the anode assembly, increasing energy consumption per unit. Difficulty in detaching the phosphorus iron ring from the guide rod claw increases the failure rate of the phosphorus iron ring detachment equipment, affecting the continuous and stable operation of the production line and causing significant damage to anode guide rods.

[0027] refer to Figure 1 This embodiment discloses a guide rod claw head dry-dip graphite device, including a frame, a kerosene spraying mechanism 1 installed on the frame, a graphite tray 3, and a graphite loosening mechanism 4 installed directly above the graphite tray 3.
[0028] The kerosene spraying mechanism 1 includes two side plates symmetrically mounted on the frame and atomizing spray guns 5 mounted on the side plates respectively. The inlet end of the atomizing spray gun 5 is connected to a kerosene tank 6.
[0029] Because dry graphite has poor coating effect on smooth steel claws; after one dry dipping action, the graphite surface in the graphite tray is uneven, and when dry dipping is performed again, the graphite coating height on the steel claw surface does not meet the process requirements. Adding a kerosene spraying device to the front end of the graphite coating machine makes the graphite coating more uniform and firm, meeting the requirements for on-site use.
[0030] In one implementation, the inner walls of both side plates of the kerosene spraying mechanism 1 are arc-shaped to reduce spillage when spraying is not possible. Alternatively, the two side plates can be connected in a closed manner to form an annular cavity, effectively preventing kerosene spillage. During use, a small amount of kerosene needs to be evenly sprayed onto the surface of the guide rod claw before dry dipping to improve the coating effect on the dry graphite. The kerosene is atomized using the atomizing spray gun 5, and a small amount of kerosene is sprayed onto the surface of the guide rod claw as it passes through the atomized kerosene zone. A small amount of kerosene is continuously and continuously supplied to the atomizing spray gun 5 via a kerosene pressure tank. Compressed air is connected at the pressure regulating valve, and the kerosene pressure inside the tank is adjusted by regulating the pressure valve, thereby controlling the kerosene flow rate at the tank outlet.
[0031] A guide rod straightening mechanism 2 is installed on the frame, above the kerosene spraying mechanism 1 and above the graphite tray 3 respectively; specifically, the guide rod straightening mechanism 2 is a guide rail.
[0032] refer to Figure 2 The graphite tray 3 is mounted on the frame via a slewing bearing. The graphite loosening mechanism 4 includes a pneumatic actuator 41 mounted above the graphite tray 3 via the frame, a telescopic rod 44 mounted on the pneumatic actuator 41, a rotating shaft 42 that cooperates with the rotating part of the pneumatic actuator 41, a directional sleeve 43 that slides with the telescopic rod 44, and a loosening claw 45 connected to the rotating shaft 42.
[0033] The directional sleeve 43 is mounted on the rod straightening mechanism 2; the graphite tray 3 is mounted on the inner ring of the slewing bearing; a gear motor for driving the inner ring of the slewing bearing is mounted below the frame; and a meshing gear ring is mounted at the lower end of the inner ring of the slewing bearing.
[0034] In one embodiment, the graphite tray 3 includes a trough and a lifting device for controlling the up and down movement of the trough. After the guide rod claws are fully placed in the turntable, the turntable rises and begins to rotate under the action of the rotating motor, allowing the guide rod claws to apply the coating. After the programmed rotation time, the turntable stops rotating and falls.
[0035] The graphite loosening mechanism 4 is used to smooth the graphite surface and loosen the graphite. After the guide rod passes the graphite tray 3, the pneumatic graphite loosening device rotates 90°, and the graphite tray 3 begins to rotate. After reaching the programmed rotation time, the graphite tray 3 stops rotating, and the loosening device resets. When dry-dipping graphite is performed, the lower cylinder of the graphite coating machine actuates, and the graphite tray 3 moves upward. The telescopic rod 44 of the graphite loosening mechanism 4 is a sliding structure, and the loosening device moves upward synchronously with the graphite tray. After dry dipping is completed, the graphite tray 3 moves downward, and the loosening device resets under the action of gravity. After installing the graphite loosening mechanism 4, the graphite dipping height on the surface of the steel claw body meets the process requirements.
[0036] refer to Figure 3 The top of the kerosene tank 6 is equipped with a filling port 61 and a pressure regulating valve 62. The atomizing spray gun 5 is connected to the interior of the kerosene tank 6 through a conduit, and a flow regulating valve 64 is installed on the conduit. A filter 63 is installed at the bottom of the conduit.
[0037] In this embodiment, a rotation drive mechanism and a lifting adjustment mechanism are installed at the bottom of the graphite tray 31.
[0038] refer to Figure 4 The rotary drive mechanism includes a support 37, a slewing bearing mounted on the support 37, a lifting column 39 inserted into the inner shell of the slewing bearing via a keyway, a turntable motor 38 that drives the inner shell of the slewing bearing to rotate, and a lifting turntable 33 mounted on the top of the lifting column 39; wherein the graphite tray 31 is mounted on the lifting turntable 33 via a lifting shaft 32 and a guide column 310.
[0039] The lifting adjustment mechanism includes a telescopic cylinder 36 installed below the support 37, wherein the telescopic end of the telescopic cylinder 36 contacts the lower end of the lifting support column 39 through a plane bearing.
[0040] The inner shell of the slewing bearing is equipped with a driven bevel gear 35, and the turntable motor 38 is provided with a motor bevel gear 34 that meshes with the driven bevel gear 35 for transmission.
[0041] refer to Figure 4The rotation and lifting of the graphite tray 31 are driven by a motor 8, gear transmission, and hydraulic system, respectively. The rotating part of the turntable is powered by a turntable motor 38, using a gear transmission system. The motor 38 drives the main gear 34 to rotate, and the main gear 34 meshes with the driven gear 35 at the bottom of the turntable, causing the turntable 33 to rotate around its central axis. A telescopic cylinder 36 serves as the power source. The telescopic cylinder 36 is fixed to the base, and its piston rod is connected to the lower end of the lifting support column 39 via a plane bearing. Its top passes through a hollow shaft, and the other end is fixed to the bottom of the graphite tray 31. When the telescopic cylinder 36 operates, the piston rod extends, lifting the lifting support column 39. The lifting support column 39 passes through the inner shell or outer guide sleeve of the slewing bearing, lifting the graphite tray 31, thus raising the graphite tray 31. The telescopic cylinder 36 then moves in the opposite direction, driving the lifting turntable 33 back to its initial position.

Any modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
