Abstract
The invention relates to a material throwing type scattering device of a cement production preheater. The material throwing type scattering device comprises an air pipe (1), and a material scattering box (4) is arranged on the outer wall of one side of the air pipe and is provided with a feeding port (7), a discharging port (10) and a material poking hole (2). The material throwing type scattering device is characterized in that a material throwing wheel (8) is arranged in the material scattering box, a set of material scraping plates (9) are arranged on the outer circumference of the material throwing wheel, a buffering bin (6) and a material limiting port (5) are formed below the feeding port (7) in sequence, and the feeding port is communicated with the material scattering box through the buffering bin and the material limiting port. By means of the technical scheme, materials fed into the air pipe are scattered more evenly, the materials make full contact with hot air, the heating effect on the materials of the hot air is better, and the energy-saving effect of the device is obviously improved.
Description
Technical field:
The present invention relates to a kind of clinker production equipment, particularly a kind of manufacture of cement preheater material-throwing type material-strewing device.
Background technology:
In new type nonaqueous cement grog technique, material can be added in the airduct of preheater, utilizes waste heat to carry out preheating to material, for this reason, on preheater airduct, is provided with material-strewing device, to material is sprinkled in airduct equably.
Material-strewing device is tilting downwards straight-through, be provided with material inlet and material outlet, material inlet is connected with feed facility, material outlet is connected with airduct, and the residual heat air current in airduct upwards, utilizes downward material and the collision of thermal current upwards to break up, add thermal material, the uniformity that is sprinkled into material in airduct is better, material contacts more abundant with hot gas, hot gas is better to heating material effect, and energy-saving effect is also better.But, in the time running into bulk or concentrated material, this straight-through structure cannot be accomplished even spreading, have a strong impact on the pre-heat effect of material, extensively retrieve for the problems referred to above, 201110446643.5) and patent of invention " a kind of combination adjustable the material-strewing device " (patent No.: 201410138435.2) and utility model patent " the material-strewing device " (patent No.: 201320273180.1) as China's patent of invention " a kind of material-strewing device of efficient dispersing powdery material " (patent No.:, all to adopt spreading plate gear to hit bulk or concentrated material, cannot eliminate but can only improve.
Summary of the invention:
Object of the present invention is exactly the uniformity in order to improve spreading, material casting wheel is set, drive material casting wheel with numerical-control motor, by material scraping plate, by material scattering and dish out in airduct, material can scatter after being dished out automatically, thereby reach the object of even spreading, concentrate when material when running into, buffering chamber can buffer memory material, by the limit material mouthful inventory that size control enters spreading case, so that the material that material scraping plate is dished out is even, bottom of device can play cushioning effect; Control material casting distance with numerical-control motor driving material casting wheel speed, by the limit material mouthful big or small material casting amount of controlling, remove the adhesion on material casting passage by disclosing material hole, for obtaining better effect, discharging opening is set as upwards tilting, is set to 30～150 ° with airduct angle.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of manufacture of cement preheater material-throwing type material-strewing device, it comprises: airduct, the spreading case arranging on airduct one side outer wall, charging aperture, the discharging opening arranging on spreading case and disclose material hole, is characterized in that: in described spreading case, be provided with material casting wheel, material casting wheel excircle is provided with one group of material scraping plate vertically, the biside plate of material casting wheel and spreading case is rotatably assorted, the rotation of material casting wheel is driven by motor, and the back side panel of material casting wheel and spreading case stands away, with the base plate matched in clearance of discharging opening downside; Described charging aperture downside is provided with buffering chamber, limit material mouthful successively, and charging aperture is communicated with spreading case by buffering chamber and limit material mouthful; Described discharging opening is upwards tilting, discloses material hole and is arranged on the base plate of discharging opening downside, discloses discharging one side that material hole is positioned at material casting wheel to remove the adhesion on material casting passage.
The base plate of described discharging opening downside is tilting is upwards set to 30～150 ° with the angle of airduct axis.
Described motor is numerical-control motor, and described numerical-control motor is known products.
Owing to having adopted technique scheme, material evenly enters spreading case by charging aperture by buffering chamber and limit material mouth, the material casting wheel rotating by material scraping plate by bulk material scattering and shed blast pipe, tilting discharging opening upwards plays and raises role the material of shedding, make the material shed more even, material has obtained sufficient contact with hot gas, and hot gas is to heating material better effects if, and the energy-saving effect of equipment is significantly improved.
For more detailed explanation the present invention, following accompanying drawing provides a most preferred embodiment.
Brief description of the drawings:
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention:
As shown in Figure 1, a kind of manufacture of cement preheater material-throwing type material-strewing device, it comprises: airduct 1, the spreading case 4 arranging on airduct one side outer wall, arranges charging aperture 7, discharging opening 10 and discloses material hole 2 on spreading case, it is characterized in that:
In described spreading case 4, be provided with material casting wheel 8, material casting wheel excircle is provided with one group of material scraping plate 9 vertically, the biside plate of material casting wheel and spreading case is rotatably assorted, material casting wheel drives and coordinates with motor 3, motor 3 is numerical-control motor, the back side panel 4a of material casting wheel and spreading case stands away, with discharging opening downside base plate 4b matched in clearance.
Described charging aperture 7 downsides are provided with buffering chamber 6, limit material mouth 5 successively, and charging aperture is communicated with spreading case by buffering chamber and limit material mouthful.
Described discharging opening 10 is upwards tilting, and the angle of discharging opening downside base plate 4b and airduct axis is set to 30～150 °, discloses material hole 2 and is arranged on base plate 4b above, discloses material hole and is positioned at discharging one side that material casting is taken turns.
