Abstract
A jet-and-suck blast nozzle with several air fountains arranged around the outlet of sand tube is disclosed. As the condition that the sand particles around the outlet of sand tube are energized is improved, the work-doing power of sand jet is increased.
Description
The present invention relates to a kind of have a plurality of air nozzles penetrate the suction blast nozzle.
What be applied to now that penetrating on the abrasive blast equipment inhale that blast nozzle adopts is that what is called is simply penetrated the suction structure, promptly one road pressure-air is through the nozzle high velocity jet, and the negative pressure that high velocity air produces is adsorbed onto the sand material in the bypass sand-ejecting tube road and forms sand gas jet flow in the primary air and spray through sand gas blowout pipe.This technical pattern is simple, and cost is low, and is easy to manufacture.But it is unreasonable simply to penetrate the sand flow Energy distribution of inhaling the injection of structure blast nozzle, and sandblast efficient is low.
The objective of the invention is for overcoming above-mentioned weak point, propose a kind of have a plurality of air nozzles penetrate the suction blast nozzle, sandblast efficient improves greatly during work.
Content of the present invention: a kind of have a plurality of air nozzles penetrate the suction blast nozzle, comprising that the many air nozzles of high-pressure air pipe sand-ejecting tube ring-type are penetrated inhales blast nozzle core sand gas jets, it is characterized in that: the sand-ejecting tube port that shakes out is positioned at the many air nozzles of ring-type and penetrates and inhale blast nozzle core center, plural air nozzle is on every side distributing, the high pressure gas of primary air is distributed to these and has been dwindled the air nozzle of bore and spray at a high speed by them, and the shake out space angle of port center vertical line of the axis of these air nozzles and sand-ejecting tube is identical.Sand-ejecting tube shakes out between the center vertical line and air nozzle axis of port, all keeps both not parallel also disjoint from relation between air nozzle axis and the air nozzle axis.At a distance of being positioned at the not far position of port sand gas direction of advance one side that shakes out the most nearby, in this position the sand gas jets is set between the air nozzle axis, the shake out center vertical line of port of the axis of this sand gas jets and sand-ejecting tube overlaps.
Advantage of the present invention:
1. plural air nozzle is distributed in sand-ejecting tube and shakes out around the port, thereby produces average negative pressure gravitation around port, and the distance that makes sand grains incorporate jet-stream wind shortens, and acceleration distance prolongs, and can obtain energy more fully.Thereby improve sandblast efficient.
2. non-intersect between air nozzle axis and the air nozzle axis, thus the flight path of sand grains can keep each other from, the energy loss that collision friction caused between the sand grains can significantly reduce.Thereby improve sandblast efficient.
3. be sand material density maximum the most nearby apart between the air nozzle axis, the sand gas jets just is located at here.After herein, sand gas has formed the conical hollow jet.Concentration of energy in this jet can realize limited large-minded area operation.Especially being fit to dust-free blasting machine etc. has fixedly the wide format of jet length and grinds and sweep operation.Thereby improve sandblast efficient.
4. the angle of the Space Angle of the center vertical line of axis by changing air nozzle and sand-ejecting tube port can change the angle of flare of conical hollow jet.When angle of flare reaches a certain size, can be as the blast nozzle of interior pipe sandblast.The interior pipe blast nozzle that generally adopts is the cone insertion at present, thereby be exactly to insert bullet to form taper diffusion jet in sand gas jet flow the place ahead, because the bump first of sand grains occurs in and inserts on the bullet interior tube-surface surperficial rather than to be processed, so energy loss is very big.The present invention causes the reason of taper diffusion jet to be jet angle but not to insert body, thus the present invention be used in the pipe sandblast, its energy effective utilization rate improves greatly.Thereby improve sandblast efficient.
Description of drawings: Fig. 1 is a schematic diagram of the present invention.
1 couple of the present invention is further described below in conjunction with accompanying drawing.The many air nozzles of ring-type are penetrated and are inhaled that two above air nozzles are arranged in around the end that shakes out of sand-ejecting tube 2 by the Space Angle of slightly shrinking to the center in the blast nozzle core 1, and the air nozzle axis mutually disjoints.When the pressure-air in the high-pressure air pipe 3 sprays at a high speed by these air nozzles, around the end that shakes out of sand-ejecting tube 2, form negative pressure suction force, make the sand material in the sand-ejecting tube constantly be sucked out, in the high velocity air around being dissolved into quickly, the sand gas jets 4 of a undergauge is set the most nearby apart at the air nozzle axis.Sand gas jet flow forms the conical hollow jet by sand gas jets 4 backs.
Claims (5)
