Problems solved by technology

The technical deficiency of this equipment is: because the unloading and conveying point of this equipment is at the rear of the equipment, the material conveying pipeline is relatively long, thus increasing the crushing rate of charge pellets, resulting in a certain waste of production cost, making the production of magnesium metal drop rate to some extent
However, the technical deficiency of this equipment is: due to the limitation of nozzle design technology, this equipment cannot realize long-distance slag removal, and can only fully extend the material delivery conduit into the reduction tank, and the reduction slag in the tank can only be removed after reaching the bottom of the tank Clean, causing the equipment to have the defects of long fuselage, huge rack and overweight equipment

Embodiment 1

[0018] Embodiment 1——Single reduction tank charge pellet Pneumatic filling operation

[0019] When working on a single reduction tank, the lateral travel device (6) controlled by the hydraulic cylinder moves forward to the position of the reduction tank mouth, the main transmission mechanism (3-1) stops automatically after running in place, and the main transmission mechanism (3-1) runs Enter the reduction tank, start the Roots blower (4) and the corner belt conveyor (5) at this time, and start charging. The Roots blower (4) then runs the main transmission mechanism (3-1) and automatically shuts down after falling back into place.

Embodiment 2

[0020] Example 2 - for Reduction tanks with different arrangement heights Perform pneumatic filling operations

[0021] When working on reduction tanks with different arrangement heights, the fuselage (3) is lifted in the vertical direction by the action of the fuselage lifting mechanism (2) controlled by the hydraulic cylinder, and the fuselage (3) is aligned with the recovery tank to be removed. Then perform the above actions after the position of the center line of the machine.

Embodiment 3

[0022] Embodiment 3——Single reduction tank Scrapping operation

[0023] When working on a single reduction tank, the lateral travel device (6) controlled by the hydraulic cylinder moves forward to the position of the reduction tank mouth, the Roots blower (4) is started, and the main transmission mechanism (3-1 ) into the reduction tank, the reduction slag is discharged from the equipment through the air supply pipeline (8) in the main transmission mechanism (3-1), and the dust enters the dust collector (1) for processing; at this time, the Roots blower (4 ), the main transmission mechanism (3-1) stops automatically after running in place, and the running transverse travel device (6) retreats in place and stops.

Abstract

The invention relates to smelting equipment, especially to an integrated mechanical automation machine for pneumatic packing of furnace charge pellets in a magnesium metal reduction tank and for pneumatic raking of high temperature reducing slag in the tank. The machine is applicable to pneumatic packing of furnace charge pellets and pneumatic raking of reducing slag for a ferrosilicon-process semi-continuous magnesium-smelting external heating type transverse tank. The machine is characterized in that high-flow high-pressure air flow of a Roots blower is used as material conveying power, all the units are mounted on a main running gear which walks in virtue of motor-driven rollers, and a machine body which is controlled by a hydraulic mechanism and can vertically rise and fall and a transverse running gear are arranged on a frame. An air supplying and material conveying pipeline is delivered to the reduction tank through a main drive mechanism on the machine body, reducing slag and pellet furnace charge are introduced into the air supplying and material conveying pipeline at different times and discharged from the reduction tank in virtue of the high-pressure air flow of the Roots blower, and produced dust is collected and cleaned. The machine has a high degree of automation and can both thoroughly remove reducing slag in the tank and intactly pack pellet furnace charge.

Description

technical field [0001] The invention relates to an integrated mechanical automation equipment which utilizes the large-flow high-pressure airflow of a Roots blower as the power for material conveyance, and is used for pneumatic filling of furnace material pellets in a metal magnesium reduction tank and pneumatic removal of high-temperature reduction slag. It is suitable for silicon Pneumatic filling of charge pellets and pneumatic removal of reducing slag in externally heated horizontal tank for thermal semi-continuous magnesium smelting. Background technique [0002] Known domestic patent No. CN200920144136.4 (authorized announcement date on May 26, 2010) discloses a kind of " air flushing type slag removal machine ". The slag removal machine includes a longitudinal translation car, a device installed on the longitudinal translation car that can drive the discharge device to move laterally and up and down. The beam is installed on the longitudinal translation car. Extend t...
