Drying and sieving device for soft magnetic material powder

Abstract

The invention discloses a drying and screening device for soft magnetic material powder, which comprises a screening box, a material guide cylinder, a material storage tank and a heating box. The screening box is provided with a movable upper cover, a feeding pipe, a threaded connection cover, Sealed bearing, air pipe, filter bag, collision protrusion, telescopic protrusion, transmission wheel, motor, first guide bottom plate and first material guide pipe; the material guide cylinder is equipped with electric telescopic rod, piston plate, second guide The bottom plate and the second material guide pipe; the storage tank is provided with a threaded sealing cover, an exhaust pipe and a connecting hose; the lower end of the screening box is provided with a support rod and a support sleeve; There are heating pipes, air intake holes and air guide pipes. In the present invention, through the filter bag, the collision protrusion and the telescopic protrusion, the passing efficiency is improved by collision and friction during rotation, the piston is driven by the electric telescopic rod to produce a circulation effect, and the air is heated by the heating tube, thereby drying the powder and improving the screening efficiency.

Description

technical field [0001] The invention relates to a sieving device for powder metallurgy, in particular to a drying and sieving device for soft magnetic material powder. Background technique [0002] Soft magnetic alloy is a kind of alloy with high magnetic permeability and low coercive force in weak magnetic field. This kind of alloy is widely used in the radio electronics industry, precision instruments and meters, remote control and automatic control systems. It is mainly used in energy conversion and information processing. It is an important material in the national economy. Iron-silicon material powder is an important raw material for manufacturing soft magnetic alloys in the field of powder metallurgy. The difference in powder particle size and the change of material composition ratio have a great impact on the properties of the formed soft magnetic alloy. [0003] The sieving of general soft magnetic material powder is usually sieved by hand in ordinary laboratories, ...

AI Technical Summary

Problems solved by technology

[0003] The sieving of general soft magnetic material powder is usually sieved by hand in ordinary laboratories, so the sieving efficiency is relatively low and takes a long time, and the sieving efficiency is low; when the amount of powder is large, the vibrating sieve machine is generally selected , but lack of continuity; soft magnetic materials are very easy to absorb water vapor, and the wet powder is more difficult to screen due to powder agglomeration
