Description

Magnetic filtering device

Technical Field

The utility model relates to the technical field of cement processing equipment, in particular to a magnetic filtering device.

Background

Cement, powdery hydraulic inorganic cementing material. The water is added and stirred to form slurry, which can be hardened in air or water and firmly bond sand, stone and other materials together.

The cement is made up by using limestone and clay as main raw materials, breaking, proportioning, grinding to obtain raw material, then feeding the raw material into cement kiln to calcine the raw material, then adding proper quantity of gypsum into the clinker and grinding. Because the main raw materials are limestone and clay, impurity removal in the cement production process is necessary, because a large amount of impurities exist in the cement production raw materials, some larger impurities can be treated by filtering through a screen, but smaller particles exist, impurities which are not easy to treat, such as smaller scrap iron, can cause unstable engineering construction due to oxidation and corrosion of the scrap iron in the use process if the scrap iron is not thoroughly filtered in the cement production, so that the engineering quality is reduced, and potential safety hazards are caused. At present, although a filtering device for filtering scrap iron in cement by adopting magnetic force is adopted, the continuous filtering property is poor, and the filtering device is not suitable for removing impurities in the production process of the cement in a pipelining manner, so that a need exists for a purifying device capable of continuously removing impurities from scrap iron in the cement.
