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 novel dry-method cement clinker technique, material can be added in the airduct of preheater, utilizes waste heat to carry out preheating to material, for this reason, preheater airduct is provided with material-strewing device, to being sprinkled into equably in airduct by material.
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 that downward material and the collision of thermal current are upwards broken up, heated material, the uniformity being sprinkled into material in airduct is better, material and hot air impingement more abundant, hot gas is better to heating material effect, and energy-saving effect is also better.But, when running into bulk or concentrated material, this straight-through structure cannot accomplish 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 high efficiency dispersion granular material " (patent No.:, all adopt spreading plate gear to hit bulk or concentrated material, but can only improve and cannot eliminate.
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, dish out in airduct by material scraping plate by material scattering, material can scatter after being dished out automatically, thus reach the object of even spreading, when running into concentrated material, buffering chamber can buffer memory material, controls by limit material mouth size the inventory entering spreading case, the material of dishing out to make material scraping plate is even, and bottom of device can play cushioning effect; Drive material casting wheel speed to control material casting distance with numerical-control motor, control material casting amount by limit material mouth size, expect that the adhesion on material casting passage is removed in hole by disclosing, for obtaining better effect, discharging opening is set as upwards tilting, is set to 30 ~ 150 ° with airduct angle.
To achieve these goals, present invention employs following technical scheme:
A kind of manufacture of cement preheater material-throwing type material-strewing device, it comprises: airduct, the spreading case that airduct side outer wall is arranged, the charging aperture that spreading case is arranged, discharging opening and disclose material hole, it is characterized in that: be provided with in described spreading case material casting wheel, material casting wheel excircle be 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 on the downside of discharging opening; Be provided with buffering chamber, limit material mouth on the downside of described charging aperture successively, charging aperture is communicated with spreading case with limit material mouth by buffering chamber; Described discharging opening is upwards tilting, discloses material hole and is arranged on the base plate on the downside of discharging opening, discloses material hole and is positioned at the discharging side of material casting wheel to remove the adhesion on material casting passage.
Base plate on the downside of described discharging opening 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 have employed technique scheme, material evenly enters spreading case by charging aperture by buffering chamber and limit material mouth, bulk material scattering is shed blast pipe by material scraping plate by the material casting wheel rotated, tilting discharging opening upwards plays the material shed and raises role, make the material shed evenly, material and hot gas obtain sufficient contact, and hot gas is to heating material better effects if, and the energy-saving effect of equipment is significantly improved.
In order to more detailed explanation the present invention, followingly accompanying drawings provide a most preferred embodiment.
Accompanying drawing illustrates:
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 that airduct side outer wall is arranged, and spreading case is arranged charging aperture 7, discharging opening 10 and discloses material hole 2, it is characterized in that:
Material casting wheel 8 is provided with in described spreading case 4, 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 with motor 3 and coordinates, motor 3 is numerical-control motor, the back side panel 4a of material casting wheel and spreading case stands away, with base plate 4b matched in clearance on the downside of discharging opening.
Be provided with buffering chamber 6, limit material mouth 5 on the downside of described charging aperture 7 successively, charging aperture is communicated with spreading case with limit material mouth by buffering chamber.
Described discharging opening 10 is upwards tilting, and on the downside of discharging opening, the angle of base plate 4b and airduct axis is set to 30 ~ 150 °, discloses material hole 2 and is arranged on base plate 4b, discloses the discharging side that material hole is positioned at material casting wheel.
Owing to have employed technique scheme, material evenly enters spreading case by charging aperture by buffering chamber and limit material mouth, bulk material scattering is shed blast pipe by material scraping plate by the material casting wheel rotated, tilting discharging opening upwards plays the material shed and raises role, make the material shed evenly, material and hot gas obtain sufficient contact, and hot gas is to heating material better effects if, and the energy-saving effect of equipment is significantly improved.
