A kind of slag removal machine for magnesium smelting reduction tank

Abstract

The present invention provides a slag removal machine for magnesium smelting reduction tank, which is used to clean the magnesium slag in the reduction tank. The slag removal machine includes a frame with supporting feet and parallel guide rails, a slag removal mechanism and The walking mechanism, the walking mechanism includes a hydraulic cylinder fixed on the frame, and a walking trolley connected with the hydraulic cylinder. The slag removal mechanism includes a transmission part and a traction part that drives the transmission part to move back and forth along the guide rail. The transmission part is equipped with The slag dumping assembly, and the slag shovel connected by the longitudinal connecting rod, the slag dumping assembly is used to control the turning of the slag shovel, and the slag dumping mechanism also includes a lifting mechanism installed on the frame, and the lifting mechanism The slag shovel on the connecting rod can be lifted, and the slag removal machine according to the present invention has the function of automatic slag removal, which can replace the high-temperature slag in the manual reduction tank for cleaning, greatly reducing the labor intensity of workers, good slag removal effect, and free Activities, a wide range of work.

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...

AI Technical Summary

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.
