Fig. 3 is the side sectional view of rectifying tube of the fluidic device of the air curtain installation that provides of a kind of embodiment of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of air curtain installation that the utility model provides, this air curtain installation comprises air-supply arrangement 1, ajutage 2 and fluidic device 3, one end of ajutage 2 is connected to the air outlet of air-supply arrangement 1, and the other end of ajutage 2 is connected to an end of fluidic device 3, and the other end of fluidic device 3 forms jet orifice, wherein, this air curtain installation also comprises drainage system, and an end of this drainage system forms draining hole, and the jet orifice of described draining hole and described fluidic device is staggered relatively.
Described drainage system comprises exhaust blower 6, exhaust duct 5 and drainage tube 4, one end of exhaust duct 5 is connected to the air inlet of exhaust blower 6, the other end of exhaust duct 5 is connected to an end of drainage tube 4, and the other end of drainage tube 4 forms draining hole, and described draining hole is positioned at the other end of drainage tube 4.
As shown in Figure 2, described fluidic device 3 also comprises air accelerating tube 31, rectifying tube 32 and the jet pipe 33 that connects in turn, and an end of air accelerating tube 31 connects ajutage, and an end of jet pipe 33 is a jet orifice.The various piece of described fluidic device, i.e. air accelerating tube 31, rectifying tube 32 and jet pipe 33, can adopt thickness is that the galvanized sheet of 0.8mm is made, and can adopt flange to connect between the various piece to carry out fixedly connected.
The caliber of described air accelerating tube 31 is taper convergents, the end that caliber is big connects ajutage 2, the other end connects an end of rectifying tube 32, the structure of this caliber convergent, stream pressure by this air accelerating tube 31 is reduced, dynamic pressure improves, and wind speed strengthens gradually, comes by rectifying tube 32 thereby formed high velocity air.
As shown in Figure 3, described rectifying tube 32 is for waiting pipe of caliber, and promptly its caliber remains unchanged, and with the speed of steady air flow, is fixed with a plurality of barriers 21 that equidistant parallel is arranged in the rectifying tube 32, plays the effect that keeps airflow direction.
The caliber of described jet pipe 33 is taper convergents, and the end that caliber is big connects rectifying tube 32, and the end that caliber is little is a jet orifice, and this jet pipe 33 can play the effect that the air of this jet pipe 33 is flow through in further raising.
Like this, when wind that ajutage 2 is sent arrives this fluidic device 3 that comprises air accelerating tube 31, rectifying tube 32 and jet pipe 33, convergent along with air accelerating tube 31 calibers, stream pressure reduces, dynamic pressure improves, wind speed strengthens gradually, form high velocity air by rectifying tube 32, the caliber that remains unchanged of this rectifying tube 32 and the parallel barrier of its inside 21 make by this rectifying tube 32 airflow layer everywhere wind speed be consistent substantially, direction is identical, further improve wind speed through jet pipe 33 again, equably from the jet orifice ejection, form the air layer of tentiform at a high speed.
The caliber of described drainage tube 4 is the taper convergent, and wherein the end that caliber is little is connected to exhaust duct 5, and the end that caliber is big is a draining hole, places with respect to jet orifice, to reduce the pressure of air draft.During exhaust blower 6 operations, exhaust outlet pressure reduces, and air enters draining hole near the traction.
Described jet pipe 33 can be for a plurality of, and these a plurality of jet pipes are row's shape and distribute, and an end of each jet pipe 33 is connected with rectifying tube 32, the other end is a jet orifice, the caliber of each jet pipe 33 is all less, and the width after the arrangement equals the width of rectifying tube 32, to form air-flow more fast.Correspondingly, described drainage tube 4 is a plurality of, and a plurality of drainage tubes 4 are relative with a plurality of jet pipe 33, also is row's shape and distributes, and an end of each drainage tube 4 is connected with exhaust duct 5, and the other end is a draining hole, places with respect to jet orifice.When being used to spray room 7, can select the caliber of the air accelerating tube 31, rectifying tube 32, jet pipe 33 etc. of ajutage 2, exhaust duct 5, fluidic device 3, so that the width that is after the arrangement of jet orifice that row's shape distributes and draining hole is roughly the same with the gateway width in spray room 7, so just can make air curtain be covered with the gateway of spraying 7 both sides, room.
Described air-supply arrangement 1 can adopt any air-supply arrangement known in those skilled in the art, can comprise pressure fan and filter element etc., and an end of filter element connects the air outlet of pressure fan, and the other end connects an end of ajutage 2.The air that filter element is used for pressure fan is sent into ajutage 2 filters, air itself with the air curtain that guarantee to form does not carry a large amount of dust, the filter of different brackets be can require to be provided with according to the cleanliness factor in places such as spray room, filter, medium effeciency filter and high efficiency particulate air filter etc. imitated as before.And, this air curtain installation can with the air-supply arrangement in shared spray room, simple structure is invested less.
The air curtain installation that the utility model provides can be widely used in spraying the place that cleanliness factors such as room are had relatively high expectations, when being applied to spray room 7, the top and bottom that the fluidic device 3 and the drainage tube 4 of described air curtain installation can be installed in spray 7 gateways, room respectively, the air output that jet orifice can be set is 5000m
3/ h, wind speed are 10m/s-15m/s.Because spray room 7 environment are pressure-fired, the jet orifice air output should be slightly less than the exhaust air rate of exhaust outlet, air quantity difference equals to spray the difference air quantity of the supply and exhaust in room 7 self, thereby guarantee all to get rid of by exhaust outlet by the air of jet orifice injection place, and the air that does not have excess enthalpy enters spray room 7, can not influence the microenvironment in the spray room 7.The spray room 7 of this air curtain installation is installed, can be formed banded air layer, effectively avoid spraying high pure air and outside air mixed flow in the room 7, avoid extraneous low cleanliness factor air to enter spray room 7 at the place, gateway in spray room 7; In addition, what jet orifice sprayed can carry out the wind pouring to the surface of the work that enters spray room 7 with conveyer belt 8, reduces the dust that entering spray room 7 with workpiece; Moreover the exhaust outlet that is positioned at the lower end can play good drainage, and the structure of drainage can form the air curtain of complete closed under the last jet, plays more satisfactory sealing effect.
