The invention discloses a material scattering device of a preheater in cement production. The material scattering device comprises a material scattering box, material guiding tubes, an air blower, air ducts, a driving device and a stirring device, wherein a feed inlet is formed in one side of the top end of the material scattering box; a cache chamber and a material limiting opening are sequentially arranged below the feed inlet; the stirring device which rotates in the horizontal direction is arranged in the material scattering box; the top end of the stirring device is connected with the driving device; the driving device is positioned at the outer part of the material scattering box; feed outlets are formed in the upper ends of the side walls on the two sides of the material scattering box; the feed outlets are covered with grid plates outside; the grid plates are externally connected with the Y-shaped double-channel material guiding tubes; discharge ends of the material guiding tubes communicate with the air ducts; and the air blower blowing air upwards is arranged at the bottom of the material scattering box. The material scattering device can uniformly scatter bulk materials into the air ducts.
Description
technical field [0001] The invention relates to cement production equipment, in particular to a material spreading device for a preheater in cement production. 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 savi...
