Abstract
The invention discloses a differential kiln air inlet device, which comprises a high-pressure fan and air inlets which are arranged in the wall of a vertical kiln and are communicated with the high-pressure fan. The air inlets are multiple and are evenly distributed along the circumferential direction of the vertical kiln. Air guide devices are arranged at the air inlets. Multi-point air inlet is realized through the air inlets. After the air enters the vertical kiln, the air is evenly scattered. Moreover, air inlet directions can be controlled through the air guide devices, the air flow in the vertical kiln is adjusted to form a flow filed which is the most beneficial to cement raw material calcination and the quality of cement products is effectively guaranteed.
Description
Technical field
The present invention relates to cement manufacture plant technical field, particularly a kind of waist wind air-intake device of the shaft kiln for cement burning.
Background technology
Cement kiln mainly contains two large classes at present, a class be kiln cylinder body horizontally-arranged and can do gyration be called rotary kiln; Another kind of kiln cylinder body be vertically-arranged do not rotate be called shaft kiln, shaft kiln has that output is high, low power consumption and other advantages.
There are following 2 deficiencies in existing shaft kiln: 1) existing shaft kiln is only provided with an air inlet usually on kiln wall, air needed for cement slurry calcining is passed into by this air inlet, owing to only there being an air inlet, dispersion is uneven afterwards to cause air-flow to enter in kiln, the uniformity of impact calcining, and then have influence on the quality of produced cement; 2), when air enters in kiln, be all enter along kiln body radial direction, the airflow field formed in kiln is also unfavorable for the calcining of cement slurry.
For above-mentioned deficiency, need improve existing shaft kiln, its air intake is uniformly dispersed, to ensure the calcining uniformity of cement slurry, meanwhile, also improve the airflow field in kiln, with improve the quality of production cement.
Summary of the invention
In view of this, the invention provides a kind of differential kiln air inlet device, this device adopts multiple spot air intake, meanwhile, adopts air ducting to control air intake direction, solves existing shaft kiln air inlet structure air and enters the uneven and nonadjustable technical problem of wind direction of rear dispersion.
The present invention is solved the problems of the technologies described above by following technological means:
Differential kiln air inlet device of the present invention, comprises high pressure positive blower and is arranged at the air inlet be communicated with on shaft kiln kiln wall and with high pressure positive blower, and described air inlet is multiple and uniform along shaft kiln circumference, and described air inlet is provided with air ducting.
Further, also comprise ajutage, described ajutage is circumferentially centered around outside shaft kiln, and ajutage one end is communicated with high pressure positive blower, and described multiple air inlet is all communicated with ajutage.
Further, described air ducting comprises two wind deflectors, the two ends that are articulated with air inlet both sides and is articulated with connecting rod inside two wind deflectors and two stay cords be connected with two wind deflectors respectively respectively, and the free end of described stay cord causes outside shaft kiln.
Further, described air ducting comprise two wind deflectors, the two ends that are articulated with air inlet both sides be articulated with respectively connecting rod inside two wind deflectors with for promoting the electric cylinder that wind deflector rotates and the controller be connected with the control circuit of electric cylinder, described electric cylinder one end and wind deflector hinged, the other end and shaft kiln inwall hinged.
Beneficial effect of the present invention: differential kiln air inlet device of the present invention, comprise high pressure positive blower and be arranged at the air inlet be communicated with on shaft kiln kiln wall and with high pressure positive blower, described air inlet is multiple and uniform along shaft kiln circumference, described air inlet is provided with air ducting, multiple spot air intake is realized by multiple air inlet, air enters after in kiln and is uniformly dispersed, simultaneously, air intake direction can be controlled by air ducting, regulate airstream in kiln to form the flow field being conducive to cement slurry calcining most, effectively ensure the quality of cement products.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of another embodiment of the present invention.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as shown in the figure: the differential kiln air inlet device of the present embodiment, comprise high pressure positive blower 1 and be arranged at the air inlet 3 be communicated with on shaft kiln 2 kiln wall and with high pressure positive blower 1, described air inlet 3 be 6 and along shaft kiln 2 circumference uniform, from shaft kiln circumference multiple spot air intake, can make to enter the air dispersion of shaft kiln evenly, be conducive to the calcining of cement slurry, improve produce the quality of cement, described air inlet 3 is provided with air ducting, air ducting adjustable air intake direction, as shown in the figure, the air intake direction of each air inlet is adjusted to along the clockwise of shaft kiln or counter clockwise direction, air-flow can be made to form Swirling Flow, more be conducive to raw material calcining.
As the further improvement of technique scheme, also comprise ajutage 4, described ajutage 4 is circumferentially centered around outside shaft kiln 2, and ajutage 4 one end is communicated with high pressure positive blower 1, and described multiple air inlet 3 is all communicated with ajutage 4, because shaft kiln height is higher, waist wind air inlet is positioned at higher position, and distance high-voltage blower fan distance is longer, and above-mentioned layout can meet all air inlets all can share a Fans, and duct length required when implementing is the shortest, implementation cost is low.
As the further improvement of technique scheme, described air ducting comprises two wind deflectors 5, the two ends that are articulated with air inlet 3 both sides and is articulated with connecting rod 6 inside two wind deflectors 5 and two stay cords 7 be connected with two wind deflectors 5 respectively respectively, the free end of described stay cord 7 causes outside shaft kiln 2, by pulling two stay cords, wind deflector can be made to rotate around its interface point, thus change wind-guiding direction, this is simple and reasonable, implementation cost is low, and is easy to operation.
Another kind of embodiment also can realize object of the present invention, described air ducting comprises two wind deflectors 5 being articulated with air inlet 3 both sides, two ends be articulated with respectively connecting rod 6 inside two wind deflectors 5 with for promoting the electric cylinder 8 that wind deflector 5 rotates and the controller 9 be connected with the control circuit of electric cylinder 8, described electric cylinder 8 one end and wind deflector 5 hinged, the other end and shaft kiln 2 inwall hinged, the flexible of electric cylinder can be controlled by controller, thus control wind deflector rotates around pin joint, reach the object controlling air intake direction, this structure operation is convenient, and be convenient to carry out automatic improving.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
