The specific embodiment
Below, embodiments of the present invention are described with reference to the accompanying drawings.
The blast injection device that utilizes air amplifier that the present invention relates to, as shown in Figures 1 and 2, comprise the compressed air hose that is divided into two conduits 100 that is connected compressed-air actuated feed unit, and be combined in described compressed air hose 100 top, be erected between the compressed air hose 100 dichotomous, together attract surrounding air with compressed air, supply to the air amplifier 200 in the bag hose 300 as shown in Figure 4.
At this moment, described bag hose 300 (Bag Filter) is arranged to a plurality of several column in order to collect the air dust that flows into precipitron 400 chamber interior, and this bag hose is with the bag (Bag) of nonwoven etc. and is configured in a bag cage (Bag Cage) formation of described inside.
Described compressed air hose 100, same as the prior art, be disposed on the upside of described bag hose 300 at a certain distance, connect compressed air supply unit, become and supply with compressed-air actuated transfer pipeline.In addition, described compressed air supply unit also comprises following formation: the air tank (not shown) of storing compressed air, produce the pulse valve (not shown) of pulse (Pulsing) with ball valve (not shown) on this tank connected connecting piece and the feasible compressed air that supplies to described compressed air hose 100 that is arranged on described ball valve downside.
At this moment, described compressed air hose 100 becomes two from the connecting portion branch of described compressed air supply unit, is made of the branched pipe 110 that is separated into two pipelines.And above the described branched pipe 110, upwards perforation forms the compressed-air actuated ejiction opening 120 of ejection.At this moment, it is airtight that yes in the bottom of branched pipe 110.Described ejiction opening 120 is erected on the branched pipe 110 and forms a plurality ofly, and best is that each ejiction opening 120 is combined in respectively on the described branched pipe 110 along direction vertical with the center line of compressed air hose 100.
Described air amplifier 200, as shown in Figure 3, be formed with following structure: the compressed air input port 210 that combines with the ejiction opening 120 that on described branched pipe 110, forms and leaked-in air is strengthened to the compressed air outlet 220 that certain multiplying power is discharged to the side by described compressed air input port 210.
At this moment, described air amplifier 200 is erected at and is attached on two branched pipes 110, and the path that surrounding air is attracted to bag hose 300 is in the space between described two branched pipes 110.
For this reason, described compressed air input port 210 is in conjunction with the bottom surface of the described air amplifier 200 of ejiction opening 120 formation, and described ejiction opening 120 is respectively formed on two branched pipes 110 along the direction vertical with the center line of compressed air hose 100.
In addition, described compressed air outlet 220 is towards the inside center line of compressed air hose 100, form with described two branched pipes 110 in the air incidence into about 90 ° of angles.For this reason, constitute first guide part 221 of the mobile path of input air and second guide part 222 forms circle along the inner peripheral surface of described air amplifier 200 side.
And then the vertical extension that the below from described second guide part 222 to branched pipe 110 forms forms the guide pipe 230 of tubulose.For this reason, along with the compressed air of described first guide part 221 and 222 discharges of second guide part stream, the air of upper space that is full of described air amplifier 200 is under the situation of the interference that is not subjected to surrounding devices, and the direction to bag hose 300 attracts simultaneously.That is to say that the opposite direction that is 180 ° with the direction that drops into air to compressed air input port 210 by described branched pipe 110 is discharged air, will be attached to the contaminant removal on the bag hose.
Described air amplifier 200 is erected on two branched pipes 110, in order to attract surrounding air, its top is formed on bagel (donut) shape of middle body perforation, and its underpart forms the tubulose guide pipe 230 from described second guide part 222 to the below of branched pipe 110.
At this moment, described ejiction opening 120 just constitutes with the shape of boring a hole, described compressed air input port 210 faces down with the tubular lower of circle and prolongs certain length, after being sandwiched in the inside of described ejiction opening 120, utilize welding or bolt to connect and firmly fixing, also can be described ejiction opening 120 certain length of outstanding formation on branched pipe 110 on the contrary, after this ejiction opening 120 is sandwiched in the inside of the described compressed air input port 210 of just having worn the hole, utilize welding or bolt to connect and firmly fixing, these need not add to give unnecessary details.
Below, utilize the effect of the blast injection device of air amplifier to describe to of the present invention.
As Fig. 4 is represented, after the dust agglutination of air by precipitron 400 is cleaned, on bag hose 300, adhere to pollutant, by two branched pipes coming out from compressed air supply unit branch 110 intermittently or supply with compressed air continuously with certain hour.Such compressed air is supplied with by the ejiction opening 120 that top is open, and compressed and supplied air like this is through the compressed air input port 210 inflow air amplifier 200 of air amplifier 200.
Described air amplifier 200 strengthens the compressed air that drops into, through form compressed air outlet 220 discharges of side towards the center line of described branched pipe 110, at interior side direction.At this moment, first guide part 221 and its discharge direction of second guide part, 222 guiding by described air amplifier 200, direction from air amplifier 200 discharges, as the dotted line of Fig. 3 2., through described compressed air input port 210,1. on different planes, discharge with about 90 ° angle with the dotted line of incidence.
In addition, the compressed air of discharging along described second guide part 222 and guide pipe 230, flows into dotted line direction 3., meanwhile, there is not the surrounding air of bound free state to flow into together on the top of described air amplifier 200 according to dotted line direction 4..
That is to say, the compressed air that has been enhanced in described air amplifier 200 is attracted with the air on its top, supply to the direction of bag hose 300 along guide pipe 230, with the air ratio of supplying with from described compressed air supply unit, reach about 20~40 times a large amount of air and supply to bag hose 300, increased the efficient of taking off the dirt effect.At this moment, attract the top of the air amplifier 200 of described surrounding air, owing to there is not other equipment,, can directly demonstrate in the enhancing efficient of air amplifier 200 so can accomplish to minimize to the obstruction of surrounding devices.
On the other hand, compressed-air actuated conduit is to form in that the form that is the center branched pipe 110 that is divided into both sides is balanced with described guide pipe 230, and the compressed air that flows into guide pipe 230 is distributed equably, supplies with, can prevent the not exclusively generation of disengaging.
The present invention is not subjected to the qualification of above-mentioned specific preferred embodiment; according to basic conception of the present invention from the request of claim; those skilled in the art can carry out various enforcement distortion, and such distortion is the protection domain that belongs to claim of the present invention.
