Abstract
The utility model discloses a new type spray nozzle of air current smashing middle particle acceleration, belonging to the material feeding auxiliary device technology field. The utility model is comprises of a sonic velocity (supersonic velocity) spray nozzle and a material spray nozzle, and the material spray nozzle 1 is coaxially fixed in the sonic velocity (supersonic velocity) spray nozzle. The outlet of the material spray nozzle is located at the throat part of the sonic velocity (supersonic velocity) spray nozzle. The acceleration effect of the utility model to particles is good and the abrasion to the spray nozzle is less.
Description
(1) technical field: the utility model discloses the new type nozzle that particle quickens in a kind of air-flow pulverizing, belong to feeding servicing unit technical field.
(2) background technology: tradition has two kinds to the particle accelerated mode, and a kind of is that particle mixes with air-flow after nozzle quickens, though this mode has realized the acceleration to particle, bigger to nozzle abrasion; A kind of is that air-flow leans on jet expansion high velocity air ejector action with particle again after nozzle quickens, and realizes that particle quickens, though this mode avoids particle to nozzle abrasion, to the poor effect of particle acceleration.
(3) summary of the invention:
1, goal of the invention: the purpose of this utility model is the deficiency at the prior art scheme, by the improvement to its structure, provides a kind of to the good and new type nozzle few to nozzle wear of pulverized particle acceleration effect.
2, the technical scheme the technical solution of the utility model is:
The new type nozzle that particle quickened during a kind of air-flow was pulverized comprises (surpassing) sonic nozzle 2 and substance nozzle 1, it is characterized in that described substance nozzle 1 concentric is fixed in (surpassing) sonic nozzle 2; And the outlet of substance nozzle 1 is positioned at the throat of (surpassing) sonic nozzle 2.
3, beneficial effect: the utility model has utilized the acceleration effect of nozzle to particle, reduced contacting of particle and nozzle tube wall, has reduced particle wearing and tearing to tube wall in the nozzle accelerator.
(4) description of drawings: be described further below in conjunction with embodiment.Figure of description is the structure chart of an embodiment of the present utility model.1 is that substance nozzle, 2 is velocity of sound or superonic flow nozzzle among the figure.Can reach goal of the invention fully through on probation.
(5) specific embodiment:
The specific embodiment of the present utility model is shown in Figure of description.It comprises (surpassing) sonic nozzle 2 and substance nozzle 1, and substance nozzle 1 concentric is fixed in (surpassing) sonic nozzle 2; The outlet of substance nozzle 1 is positioned at the throat of (surpassing) sonic nozzle 2.
Claims (2)
1, the new type nozzle that particle quickened during a kind of air-flow was pulverized comprises sonic nozzle (2) and substance nozzle (1), it is characterized in that described substance nozzle (1) concentric is fixed in the sonic nozzle (2); And the outlet of substance nozzle (1) is positioned at the throat of sonic nozzle (2).
2, the new type nozzle that particle quickened during air-flow according to claim 1 was pulverized is characterised in that described sonic nozzle (2) is a superonic flow nozzzle.
