Inner guide plate mechanism of vertical mill

Abstract

The utility model discloses an inner guide plate mechanism of a vertical mill, and belongs to the technical field of inner guide plates, the inner guide plate mechanism comprises an annular air duct, the annular air duct surrounds a millstone, an air outlet is formed in one side, facing the millstone, of the annular air duct, the air outlet direction of the air outlet faces the upper part of the millstone, a first guide plate is arranged at the bottom of the annular air duct, and a second guide plate is arranged at the bottom of the first guide plate. A first flow guide plate is arranged in the air outlet and is an annular plate guiding in the direction of the grinding disc, a second flow guide plate is arranged above the annular air channel and is in a cylinder shape with the narrow upper portion and the wide lower portion, and the second flow guide plate guides airflow sprayed out of the air outlet to the position above the grinding disc. Through blocking of the first flow guide plate, wind power of the air outlet can be prevented from moving towards the position below the grinding disc, the first flow guide plate directly guides the wind power to move towards the position above the grinding disc, slag micro-powder scattered on the grinding disc can be driven to move upwards, and the slag micro-powder is guided into the separator through guiding of the second flow guide plate.
