The invention discloses a material-throwing type uniform material scattering device of a cement preheater. The material-throwing type uniform material scattering device comprises an air duct, wherein a material scattering box is arranged on the outer wall at one side of the air duct; a feeding hole, a discharge hole and a material stabbing tube are arranged on the material scattering box; the feeding hole is formed in the upper end of the material stabbing tube; the lower side of the feeding hole is sequentially provided with a buffer bin and a material limiting hole; a material scattering wheel is in driving connection to a motor and is in clockwise rotation relative to the motor is arranged in the material scattering box; the material scattering wheel is positioned below the material limiting hole; the external circumference of the material scattering wheel is axially provided with a material scraping plate; a material baffle plate which is inclined downwards is arranged above the discharge hole; the axis of the material baffle plate and the axis of the air duct form an angle of 90-150 degrees; and the bottom plate is inclined upwards, and is provided with the material stabbing tube which is inclined downward. The device can be used for uniformly scattering the cluster materials into the air duct, so that the more sufficient the contact between the materials and hot gas, the better the energy-saving effect.
Description
technical field [0001] The invention relates to cement production equipment, in particular to a cement preheater throwing type uniform material spreading device. Background technique [0002] In the new dry process cement clinker process, the material will be added to the air duct of the preheater, and the waste heat will be used to preheat the material. Sprinkle evenly into the duct. [0003] The material spreading device is placed obliquely and straight down, with a material inlet and a material outlet, the material inlet is connected to the feeding facility, the material outlet is connected to the air duct, the waste heat in the air duct is upward, and the downward material and the upward hot air flow The collision breaks up and heats the material, the better the uniformity of the material sprinkled into the air duct, the more fully the contact between the material and the hot air, the better the heating effect of the hot air on the material, and the better the energy sa...
