AI Technical Summary

Technical Problem

Existing soft magnetic powder storage equipment lacks sufficient sealing, making it easy for oxygen and moisture to seep in, causing powder oxidation or moisture absorption, affecting magnetic properties, and it also lacks sufficient protection to effectively protect the powder.

Method used

The system employs a double-sealing structure and an inert gas filling system, combined with a stirring device, to ensure the sealing of the storage tank. The combination of an air pump and an exhaust pipe prevents oxidation reactions, while the drive motor and stirring rod prevent clogging.

Benefits of technology

It improves the sealing effect of the storage tank, prevents oxidation reaction, ensures powder quality, avoids blockage, facilitates material discharge, and enhances the protection capability of the storage equipment.

Abstract

This utility model discloses a soft magnetic powder storage device, including a fixed frame. A storage tank is installed inside the fixed frame. The upper surface of the storage tank is provided with a sealing mechanism, which includes a feeding cylinder. The bottom end of the feeding cylinder is fixedly connected to the upper surface of the storage tank. A sealing cover is provided on the outer surface of the feeding cylinder. A first rubber sealing gasket is provided on the bottom surface of the sealing cover. A second rubber sealing gasket is fixedly connected to the inner top wall of the feeding cylinder. An air pump is fixedly connected to the upper surface of the storage tank. This device, through the cooperation of the sealing cover, the first rubber sealing gasket, and the second rubber sealing gasket, can provide a double seal for the feeding cylinder, increasing the sealing effect of the storage tank and improving the protection of the soft magnetic powder. By utilizing the cooperation of the air pump, the exhaust pipe, and the gas flow valve, the inside of the storage tank can be ventilated, facilitating the introduction of inert gas into the storage tank and preventing oxidation of the soft magnetic powder.
