Description

Technical Field

[0001] The invention relates to an automatic magnesium driving device for a magnesium electrolytic cell of an assembly line, belonging to the technical field of metallurgical equipment. Background Art

[0002] The magnesium electrolysis line is composed of a plurality of tanks connected in series, such as a head tank, an electrolytic tank, and a separation tank. The electrolysis is carried out with a direct current of about 200kA. The liquid magnesium produced by the electrolytic tank is collected on the surface of the magnesium collecting chamber of each electrolytic tank and flows along the pipeline with the electrolyte, and finally collected in the separation tank and discharged from the pipeline. The tank conditions of each electrolytic tank in the pipeline are different, and the fluidity of the liquid magnesium is uneven. In some electrolytic tanks, the liquid magnesium will not flow smoothly and will gather. The gathered liquid magnesium is prone to oxidation and combustion, resulting in magnesium loss. In order to reduce the loss of magnesium caused by the poor flow of liquid magnesium in the electrolytic tank, a magnesium-chasing shovel is currently manually extended into the electrolyte liquid surface to chase the magnesium. This method has high labor intensity, low efficiency, cannot achieve continuous operation, and has a poor working environment. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the existing manual magnesium driving operation has high labor intensity, low efficiency and cannot achieve continuous operation.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an automatic magnesium-driving device for an assembly line magnesium electrolytic cell, comprising a rotating driving member, a bracket, a swinging member, a connecting rod, a magnesium-driving shovel and an adjusting rod, wherein the rotating driving member is mounted on the bracket, the swinging member is vertically connected to the output shaft of the rotating driving member, one end of the connecting rod is hinged to the swinging member, and the other end is connected to the magnesium-driving shovel, one end of the adjusting rod is hinged to the bracket, and the other end is hinged to the middle part of the connecting rod.

[0005] Wherein, the swing member in the above device is a disc structure, the output shaft of the rotating driving member passes through the swing member and is fixed to the swing member, and one end of the connecting rod is hinged to the outer edge side of the swing member.

[0006] Wherein, the swing member in the above device is a rod-shaped structure, one end of the swing member is vertically connected to the output shaft of the rotating drive member, and the other end is hinged to one end of the connecting rod.

[0007] Wherein, the adjustment rod in the above device is a telescopic rod structure with adjustable length.

[0008] The device also includes an adjustment plate, which is arranged in the middle of the connecting rod and has a number of adjustment holes arranged at intervals. The adjustment rod away from the bracket end can pass through any adjustment hole and be hinged to the adjustment plate.

[0009] Furthermore, the adjustment holes in the above device are arranged at intervals along the length direction of the connecting rod.

[0010] Among them, the connecting rod in the above device is a telescopic rod structure with adjustable length.

[0011] Among them, the adjusting rod in the above device is arranged parallel to the swinging member.

[0012] Among them, the bracket in the above device further includes a side plate, the side plate is arranged at the swinging member end of the bracket, the side plate is arranged parallel to the swinging member, and the hinged end of the adjusting rod and the bracket is located on the side plate.

[0013] Among them, the rotation driving member in the above device includes a pneumatic motor and a speed reducer connected thereto. An air inlet pipe and an exhaust pipe are arranged on the pneumatic motor, and the swinging member is connected to the output rotating shaft of the speed reducer.

[0014] The beneficial effects of the present invention are as follows: The setting of this device promotes the flow of liquid magnesium in the magnesium collecting chamber, reduces the oxidation of magnesium, and improves the magnesium recovery rate. The rotation driving member is driven to drive the operation of the actuator (magnesium driving mechanism). That is, the rotation driving member directly drives the swinging member to rotate. The actuator is a crank-rocker mechanism composed of a swinging member, a connecting rod, a magnesium driving shovel, and an adjusting rod. The rotation driving member drives the swinging member to rotate, so that the magnesium driving shovel reciprocates to increase the flow rate of liquid magnesium, thereby realizing continuous and effective magnesium driving operation, enhancing the fluidity of liquid magnesium on the surface of the electrolytic cell, preventing a large amount of liquid magnesium from oxidizing and burning due to poor flow, reducing the labor intensity of on-site personnel, and improving work efficiency.
