Description

Technical Field

[0001] The utility model relates to the technical field of magnesium material processing, in particular to a screening device for magnesium powder particles. Background Art

[0002] Magnesium exists in the earth's crust in the form of magnesite, dolomite, carnallite, etc. Magnesium is a silvery white solid with a metallic luster. It is insoluble in water and alkali solution, but soluble in acid. It is often used as a reducing agent to replace metals such as titanium, zirconium, uranium, and beryllium. Magnesium is mainly used to manufacture light metal alloys, ductile iron, scientific instruments, and Grignard reagents, etc. It can also be used to make fireworks, flash powder, magnesium salts, inhalers, flares, etc. Its structural characteristics are similar to those of aluminum, and it has various uses for light metals. It can be used as an alloy material for aircraft and missiles. In the preparation process of magnesium, it is necessary to use a chewing machine to crush the previously burned finished magnesium, and then add chemical raw materials to prepare magnesium powder particles, and then use a sieve to screen the particles of appropriate size for bagging;

[0003] After searching, the applicant found that a Chinese patent disclosed "a magnesium powder particle screening device", and its publication (announcement) number is "CN211303809U". This patent mainly divides the sieve holes into four smaller sieve holes, so that it can be used as a smaller sieve to screen magnesium powder particles. There is no need to replace the entire sieve. The first plug plate and the second plug plate can be inserted and removed at any time to change the size of the sieve holes. It is very convenient to use and can improve work efficiency. However, the device directly places the sieve plate above the opening of the container that receives the magnesium powder particles. The magnesium powder particles are easily stuck on the sieve, affecting the screening effect. For this reason, we propose a screening device for magnesium powder particles. Utility Model Content

[0039] First, the mounting plate 3 is clamped on the clamping blocks 2 on the front and rear sides of the magnesium powder collection box 1, and then the filter screen plate 7 is clamped in the clamping slot 6 opened on the right side of the mounting plate 3. After the filter screen plate 7 is clamped, the first magnetic block 8 in the clamping slot 6 will attract the second magnetic block 9 on the filter screen plate 7, and then the magnesium powder is poured from the top into the magnesium powder collection box 1 under the filter screen plate 7. When the staff observes that the filter screen plate 7 is blocked, the scraper 51 is driven to move in the slide 4 by moving the handle 53 to scrape the blockage on the filter screen plate 7 to the impurity collection boxes 12 on both sides. At this point, the entire workflow is completed.
