Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment, but do not limit protection scope and application scope of the present invention:
[0012] Such as figure 1 As shown, a cement production preheater throwing type material spreading device includes an air duct 1, a material spreading box 4 arranged on the outer wall of the air duct 1 side, a material inlet 7 arranged on the material spreading box 4, a material discharge The mouth 10 and the feed port 7 are arranged on the upper end of the material spreading box 4, and the lower side of the feed port 7 is successively provided with a buffer bin 6 and a downwardly inclined vibrating grid plug 5. The vibrating grid plug 5 is connected with the vibration motor, and the material spreading The box 4 is provided with a throwing wheel 8 that is driven and connected to the motor 3 and rotates counterclockwise. Preferably, the motor 3 is a numerically c...

The invention discloses a tossing type spreading device of a cement production preheater. The tossing type spreading device comprises an air pipe. A spreading box is arranged on the outer wall of one side of the air pipe. The spreading box is provided with a feeding port, a discharging port and first guide pipes. The feeding port is formed in the upper end of the spreading box. The lower side of the feeding port is sequentially provided with a temporary storage bin and a limiting port. The feeding port communicates with the spreading box through the temporary storage bin and the limiting port. A tossing wheel which is in driven connection with a motor and rotates anticlockwise is arranged in the spreading box. The tossing wheel is located below the limiting port. Scrapers are arranged on the outer circumference of the tossing wheel in the axial direction. A material baffle which inclines downwards is arranged above the discharging port. An included angle ranging from 90 degrees to 150 degrees is formed between the material baffle and the axis of the air pipe. A bottom plate of the spreading box inclines downwards. When the tossing wheel rotates, the scrapers rotate so that materials on the bottom plate can be driven to move. The multiple guide pipes inclining and extending downwards are arranged under a vibration grid plug. By the adoption of the tossing type spreading device, the materials can be evenly spread into the air pipe.
Description
technical field [0001] The invention relates to cement production equipment, in particular to a throwing type material spreading device for a cement production 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 ...
