Pulsed magnetic separation device for iron powder granules

Abstract

The invention discloses a pulsed magnetic separation device for iron powder granules. The device is characterized in that a vertical main flow channel is included, a main flow channel outlet is formed in the lower end of the main flow channel, a main flow channel inlet is formed in the upper end of the main flow channel, an arc-shaped flow channel which is tangent to the main flow channel and extends in the upper right direction is connected to the main flow channel inlet side, a straight flow channel which is tangent to the arc-shaped flow channel is connected to the upper end of the arc-shaped flow channel, a powder inlet is formed in the upper wall of the straight flow channel, an air source is arranged on the inlet side of the straight flow channel, at least two stages of branch channels are sequentially distributed on the right side of the main flow channel from top to bottom, stacked silicon steel sheets are arranged on the right side of the upper portion of the main flow channel, the end, close to the main flow channel, of each silicon steel sheet is shaped like a hammer, each silicon steel sheet is provided with a coil, and the coils are connected with a power supply. According to the pulsed magnetic separation device for the iron powder granules, special powder granule grading can be achieved, the equipment is small, no hole blocking problem is generated, and the adjustability is good.

Description

technical field [0001] The invention relates to a particle classification tool for powder metallurgy experiments or production, in particular to a pulsed magnetic separation device for iron powder particles. Background technique [0002] my country is a big industrial country. With the advancement of science and technology, my country's manufacturing industry is booming, the economy is becoming stronger and stronger, new technologies and materials are constantly emerging, and powder metallurgy materials are one of them. Powder metallurgy can make porous, semi-dense or fully dense parts, such as oil bearings, gears and other parts, which are widely used in various industries without cutting. It has unique chemical composition and mechanical and physical properties. Iron powder is widely used because of its low cost and strong practicability, which cannot be obtained by metal processing methods. The existing production process of iron powder powder products is generally to pr...

Problems solved by technology

The existing production process of iron powder powder products is generally to prepare powder particles with appropriate particle size, then press them into shape, and then sinter to form parts with fixed shapes. The density and product performance after sintering are directly related to the size of powder particles. , Different products have different requirements, and powder particles of different particle sizes need to be uniformly mixed in different proportions to achieve the desired effect. Therefore, it is very important to sieve iron powder particles, especially in small batch production or experiments. The most important thing is that the existing sieving is mainly through sieve screening. Due to the small size of the iron powder powder required to be prepared, the production of the sieve is difficult, the cost is high, and it is easy to block the screen and difficult to clean. Currently, more suitable for this need Practical tools are still lacking, which still needs to be solved by technology
