Description

Lifting structure of magnetic head of bottom-mounted permanent magnet stirrer

Technical Field

The utility model relates to a lifting structure of permanent magnet mixer magnetic head, especially a lifting structure of bottom mounted permanent magnet mixer magnetic head.

Background

The permanent magnet stirrer is mainly arranged at the bottom (or side) of the smelting furnace and is applied to the configuration of alloy aluminum or high-purity aluminum in the aluminum industry; and scrap aluminum (including aluminum scrap) recovery. Compared with a side-mounted permanent magnet stirrer, the bottom-mounted permanent magnet stirrer has the advantages that one stirrer can be applied to a plurality of furnaces, the equipment investment is saved, the equipment is utilized more efficiently, and the bottom-mounted permanent magnet stirrer is generally recommended to be used in newly-built casting projects. The bottom-mounted permanent magnet stirrer needs to move back and forth in a permanent magnet channel at the bottom of the furnace to stir a plurality of furnaces, and meanwhile, when the bottom-mounted permanent magnet stirrer reaches the target bottom of the furnace, a lifting magnetic head needs to be carried out, the magnetic head enters a permanent magnet window at the bottom of the furnace to start stirring, then the bottom-mounted permanent magnet stirrer descends to move again. The stirring magnetic head lifting system of the bottom-mounted permanent magnet stirrer plays a very important role, and the good lifting system structure can ensure that the magnetic head can safely lift and can stably rotate at a high speed, so that the good stirring effect is ensured. In the past, a multi-purpose turbine worm lifting structure of a bottom-mounted permanent magnet stirrer drives a chain or a shaft to synchronously drive and lift through a motor. Firstly, the synchronous effect of the worm lifting structure is not ideal, secondly, the lifting reaches a certain height, the whole machine body is easy to shake when the magnetic head rotates, then the whole machine body is shaken, the turbine and the worm are easy to damage, the lifting is failed, and the whole stirring machine cannot be normally used. At present, a hydraulic oil cylinder is generally used for replacing a worm to lift, but 4 oil cylinders are basically needed for directly lifting by using the oil cylinder or a guide post is manufactured, the oil cylinder also needs a relatively long stroke, and therefore the cost is relatively high.
