Crawler loader for magnesium smelting reduction tank

Abstract

The invention provides a crawler loader for a magnesium smelting reduction tank. The crawler loader is used for removing magnesium slag in the reduction tank. The crawler loader comprises a rack with supporting legs and parallel guide rails, a slagging-off mechanism and a walking mechanism, and the slagging-off mechanism and the walking mechanism are loaded on the rack. The walking mechanism comprises a hydraulic cylinder fixed to the rack, and a walking trolley connected with the hydraulic cylinder. The slagging-off mechanism comprises a transmission component and a traction component driving the transmission component to move back and forth along the guide rails. The transmission component is provided with a deslagging component and a slag shovel connected through a lengthwise connecting rod. The deslagging component is used for controlling overturning of the slag shovel. The slagging-off mechanism further comprises a lifting mechanism installed on the rack. The lifting mechanism can lift the slag shovel on the connecting rod in the reciprocating movement of the transmission component. The crawler loader has the automatic slagging-off function and can replace manual operation to remove high-temperature slag charge in the reduction tank, the labor intensity of workers is greatly lowered, and the slagging-off effect is good; and the crawler loader can freely move, and the work range is wide.

Description

technical field [0001] The invention relates to a smelting auxiliary equipment, in particular to a slag removal device for a magnesium smelting reduction tank used on a magnesium smelting reduction furnace. Background technique [0002] At present, the domestic magnesium smelting industry mainly adopts the Pidgeon process for magnesium smelting. The usual way to reduce magnesium is to put the prepared raw materials into the reduction tank, and carry out the reduction reaction by vacuumizing and heating the reduction tank in the reduction furnace. After the reaction is over , take out the crystalline magnesium from the reduction tank, clean up the reduction slag in the reduction tank and load it with raw materials for the next production cycle. The slag after the reaction in the reduction tank is usually manually removed. Because the temperature of the slag is very high, when the worker removes the slag, the labor intensity and work risk of the worker are very large and the e...

Problems solved by technology

[0004] The existing mechanized slag cleaning equipment is mainly a spiral slag cleaning machine, which mainly has a rigid straight shaft on which a helical blade is welded. It can only be cleaned when it is close to the lower wall of the tank, which is difficult to achieve, and the inner diameter of the reduction tank is usually inconsistent, resulting in the slag in the reduction tank not being cleaned very cleanly, which affects the charging capacity, heat transfer efficiency and service life of the reduction tank. Therefore, after the slag removal by the slag removal machine, it is often necessary to manually perform a second slag removal to clean up the remaining magnesium slag, which is time-consuming.
