Abstract
A convertible external wind nozzle relates to the technical field of multiple-duct coal powder burners for cement industry and comprises an external wind nozzle body, wherein a plurality of through holes are evenly distributed on the external wind nozzle body along the circumferential direction, and each through hole is internally connected with a hollow hexagonal bolt through screw threads, by utilizing the design, the venthole diameter of the external wind nozzle is changed from an original unconvertible venthole diameter to 2-3 convertible venthole diameters of different specifications, when trial production is carried out in cement factories, if the venthole diameter is not proper and poor in use effect, the venthole diameter can be conveniently converted on the spot, thereby achieving the optimization of external wind effects of the coal powder burners.
Description
Technical field:
The utility model relates to the technical field of cement industry with the multiple duct coal burner.
Background technology:
Cement industry is one of the key equipment in cement plant with the multiple duct coal burner, good and bad product quality, environmental protection, energy resource consumption and the economic benefit that directly influences the cement plant of this equipment performance.The operation principle of coal burner is to utilize high-speed jet wind (exogenous wind) and high-speed rotational wind, center wind and the low speed wind of delivering coal to form the high speed difference jet, make the air-flow conversion and the mixed performance of burner front portion reach optimization, thus form evenly deliver coal, fully burning, controllable combustion flame.
At present the exogenous wind nozzle of multiple duct coal burner be the hole of a plurality of fixed dimensions circumferential uniform on nozzle body, (as 20
The hole) form the exogenous wind injection channel.Can not conversion, adjusting.Can not be suitable fully in cement production process, can not reach optimization.
The utility model content:
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of exogenous wind convertible nozzle to be provided, making outer air quantity and outer monsoon intensity reach optimization.
The purpose of this utility model is achieved in that convertible exogenous wind nozzle, comprises the exogenous wind nozzle body, along the circumferential direction uniform some through holes on the exogenous wind nozzle body, and described each through hole internal thread connects the hollow type hex bolts.
With the through hole of a plurality of fixed dimensions on the nozzle body (as 20
The hole) become screwed hole (as 20 M33), other designs 2～3 cover hollow type hex bolts, be specially: bolt one end is a turret head, the other end be external screw thread (as M33) and the hollow unthreaded hole that is respectively different size (as
).
The beneficial effects of the utility model are: by above design, the exogenous wind nozzle becomes the ventilation aperture of 2～3 kinds of detachable different sizes that change by original a kind of aperture that ventilates that can not conversion, when producing as a trial in the cement plant, as find that aperture discomfort, result of use are not good, can conveniently carry out conversion at the scene, thereby reach the optimization of coal burner exogenous wind effect.
Description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 be among Fig. 1 A to view.
Among the figure: 1 exogenous wind nozzle body, 2 through holes, 3 bolts, 4 outer airducts, 5 coal airducts, 6 exogenous wind passages.
The specific embodiment:
As shown in Figure 1, 2,, comprise exogenous wind nozzle body 1 for convertible exogenous wind nozzle, along the circumferential direction uniform 20 through holes 2 on the exogenous wind nozzle body 1, each through hole 2 internal thread connects hollow type hex bolts 3.
Form exogenous wind passage 6 between outer airduct 4 and the coal airduct 5, form the exogenous wind injection channel through hollow type hex bolts 3 again.
Claims (1)
1. convertible exogenous wind nozzle comprises the exogenous wind nozzle body, and along the circumferential direction uniform some through holes on the exogenous wind nozzle body is characterized in that: described each through hole internal thread connects the hollow type hex bolts.
