The invention discloses a material spreading device for a cement preheater, which comprises a material spreading box, a material guide pipe, a blower, an air duct, a driving device and a stirring device. The top side of the material spreading box is provided with a material inlet. A buffer bin and a material limiting port are sequentially arranged below the feed inlet, and a stirring device rotating in the horizontal direction is arranged in the spreading box, and a driving device is connected to the top of the stirring device, and the driving device is located at the top of the spreading box. Externally, the upper end of the side wall of the material spreading box is provided with a discharge port, and the discharge port is also covered with a grid plate, and the outside of the grid plate is connected with a Y-shaped dual-channel material guide tube, and the guide tube The discharge end of the material pipe is connected with the air pipe, and the bottom of the material spreading box is also provided with an upward blower. The device can evenly scatter lumpy materials into the air duct.
Description
technical field [0001] The invention relates to cement production equipment, in particular to a material spreading device for a cement preheater. 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 saving effect.
