Technical Field

[0001] The utility model belongs to the technical field of iron ore concentrate dehydration and filtration, in particular to a pressure filter used for dehydration of iron ore concentrate. Background Art

[0002] Iron ore concentrate is the main raw material for pellets. It is a mineral powder made by crushing, grinding, beneficiation and other processing of iron ore. The fluctuation of iron content will directly affect the quality of the finished pellets.

[0003] For example, the Chinese patent with the announcement number CN219922293U discloses a pressurized filter for dehydrating iron ore concentrate, including a filter body and a supporting component installed at the bottom of the filter body; the pressurized filter for dehydrating iron ore concentrate, through the cooperation of the iron ore concentrate transmission mechanism, the internal parts of the drying mechanism and the vacuum machine, can maintain a certain sealing state when transmitting the iron ore concentrate, thereby preventing moisture in the outside air from entering the interior of the dehydration filter box and affecting the drying and dehydration operation of the iron ore concentrate; at the same time, the air inside the dehydration filter box can be extracted to maintain a vacuum state, thereby preventing moisture in the internal air from affecting its drying and dehydration operation, thereby improving the effect and efficiency of processing the iron ore concentrate; and through the design of the internal parts of the rotary screening mechanism, the iron ore concentrate and the impurities inside it can be screened, and after the screening is completed, the iron ore concentrate and the impurities can be classified and stored separately for subsequent processing.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, when this device dehydrates and filters the iron ore concentrate, it uses a drying method to dehydrate the iron ore concentrate. During the drying process, the iron ore concentrate is prone to agglomeration, resulting in uneven drying of the iron ore concentrate after drying, affecting the quality of the iron ore concentrate and affecting its subsequent use. In view of this, we propose a pressurized filter for dehydrating iron ore concentrate. Utility Model Content
