Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum technology, and more specifically, to a guide rod fixer. Background Technology

[0002] Electrolytic aluminum is an industrial process for refining metallic aluminum by electrolyzing alumina (Al2O3): alumina is dissolved in molten cryolite (Na3AlF6), and direct current is passed through it at about 950°C, causing the alumina to be reduced to liquid aluminum at the cathode, while oxygen is generated at the anode and reacts with the carbon electrode to produce CO2, ultimately yielding primary aluminum with a purity of 99.7%.

[0003] A search revealed an existing patent (publication number: CN208151491U) that discloses a highly reliable anode conductive rod device for electrolytic aluminum. Specifically, a long bolt is welded to the upper part of a steel beam, and a pair of clamping plates are added to the aluminum guide rod near the steel beam. These clamping plates are locked to the aluminum guide rod via a locking assembly. A compression spring is installed on the upper part of the long bolt and clamping plates, with a compression nut on the spring. Rotating the compression nut compresses the spring, and the preload generated by the spring pulls the steel beam upwards, causing the aluminum / steel interface at the junction of the aluminum guide rod and the steel beam to experience compressive stress. The final preload generated by the spring must be greater than the gravitational load of the aluminum / steel interface, thus changing the stress on the aluminum / steel interface from tensile stress to compressive stress. This design increases the connection reliability of the aluminum / steel interface and improves the overall service life of the conductive rod. Furthermore, inertial friction welding can be used to completely weld the steel rod to the steel beam, further enhancing conductivity.

[0004] After the device is put into operation, the long bolt-spring preload system transforms the conductive rod into an elastic oscillating system. The anode is disturbed by bubbles and magnetic fields, and the periodic oscillation is amplified by the elastic element, causing the busbar contacts to loosen and discharge. Due to the excessive rigidity of the full-section weld of the steel bar caused by inertial friction welding, stress is concentrated at the neck. Combined with the thinning caused by oxidation-electrolyte penetration, the heat-affected zone of the weld is prone to circumferential fatigue cracks. After the cracks propagate, the weld breaks instantly, and the steel claw and carbon block fall as a whole. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a guide rod fixator to solve the problems of elastic preload inducing swaying, stress concentration in rigid welds leading to fatigue fracture of steel bars and falling of carbon blocks.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a guide rod fixator, comprising: an aluminum guide rod; a swaying buffer device mounted on the top of the aluminum guide rod, the swaying buffer device being used to prevent movement during use; a connecting installation device mounted on the bottom of the aluminum guide rod, the connecting installation device being used for connection; a connecting beam assembly mounted on the bottom of the aluminum guide rod, the connecting beam assembly being used to fix a steel rod; and a steel rod auxiliary clamping assembly mounted on the bottom of the connecting beam assembly, the steel rod auxiliary clamping assembly being used to assist in fixing the steel rod.

[0007] Preferably, the swaying buffer device includes: a support rod one fixedly installed on the top of the aluminum guide rod, a mounting plate one fixedly installed on the top of the support rod one, a spring one fixedly installed on the top of the mounting plate one, a damping rod fixedly installed inside the spring one, and a mounting plate two fixedly installed on the top of the spring one and the damping rod.

[0008] Preferably, multiple sets of the first spring and damping rod are provided, and the multiple sets of the first spring and damping rod are equidistantly arranged between the first mounting plate and the second mounting plate.

[0009] Preferably, the connection and installation device includes: a T-shaped plate fixedly installed on one side of the aluminum guide rod, the T-shaped plate having two sets of connecting bolts symmetrically arranged inside the aluminum guide rod, and a detachable connecting bolt on the T-shaped plate, the connecting bolt being detachably installed on the aluminum guide rod.

[0010] Preferably, the connecting and mounting device includes: a connecting rod movably mounted on the T-shaped plate, a nut threadedly connected to the top of the connecting rod, and a spring movably mounted to the bottom of the nut.

[0011] Preferably, the connecting beam assembly includes: an explosively welded transition block welded to the bottom of the aluminum guide rod, a steel beam welded to the bottom of the explosively welded transition block, an installation sleeve hole fixedly installed on the top of the steel beam, and one end of the connecting rod threadedly connected to the inside of the installation sleeve hole.

[0012] Preferably, the steel bar auxiliary clamping assembly includes: a steel bar body welded to the bottom of the steel beam, a second support rod fixedly installed at the bottom of the steel beam, and a clamping block fixedly installed on one side of the second support rod.

[0013] Preferably, there are two sets of support rods and clamping blocks, and the two sets of support rods and clamping blocks are connected by a connecting bolt.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a flexible connection between the mounting plate 2 of the swaying buffer device and the busbar. Multiple sets of springs 1 and damping rods synchronously absorb the swaying energy caused by bubbles and magnetic fields, preventing the top from amplifying the sway amplitude and keeping the busbar joints pressed tightly without discharge. The connection and installation device, consisting of a T-shaped plate, connecting rod, nut, and spring 2, elastically locks the aluminum guide rod onto the steel beam, allowing for thermal expansion differences while continuously transmitting downward pressure, avoiding stress concentration in rigid welds. After the steel beam is transitioned through an explosive weld transition block, it forms an adjustable pre-tightening pair with the connecting rod through the mounting sleeve hole, ensuring that the steel beam is always under upward tension. The steel bar auxiliary clamping assembly, consisting of the steel bar body, support rod 2, clamping block, and connecting bolt 2, clamps each steel bar at multiple points, dispersing the neck bending moment and inhibiting oxidation penetration, thereby preventing the initiation of circumferential cracks and ultimately eliminating the risk of overall fall, while improving conductivity stability and service life.
