Description
The present invention relates to improved cyclone type dust collecting apparatus.Described improved cyclone type dust collecting apparatus does not have rotating mechanism, but the dust that the eddy current by air exists in air in separation chamber cylindraceous makes it disperse to cylinder inner wall portion by centrifugal force; Again the air that does not have dust of portion of cylinder center is discharged from being arranged in the separation chamber the peace and quiet air discharge pipe of central part.
Fig. 9 and Figure 10 are the cyclone type dust collecting apparatus of the disclosed prior art of Japanese patent of invention 6-91974 communique.Fig. 9 is vertical sectional drawing of this cyclone type dust collecting apparatus, and Figure 10 is the transverse cross along Fig. 9 A-A line.Among the figure, the cylindrical portion that 1 expression is connected with the upper end of inverted cone tube portion 2, the lower end of inverted cone tube portion 2 is provided with coarse grain outlet 3, in grading room 4, is provided with the counter-rotating dish 5 that the top has the circular cone shape of disc face 6 on the position of axle center, the lower end CL that is positioned at cylindrical portion 1.
On the upper wall 7 of above-mentioned cylindrical portion 1, on the position that is positioned at axle center CL, be formed with multiple exhaust structure 8 and eddy current and flow into structure 9.Above-mentioned multiple exhaust structure 8 is to constitute like this, promptly, being concentric shape ground in diameter is the urceolus 10 of d, to insert diameter be the inner core 11 of 0.7d, and extending to urceolus 10 in the grading room 4 and inner core 11 is that urceolus 10 is L apart from the distance of the disc face 6 of counter-rotating dish 5, and inner core 11 is 1/2L.In addition, urceolus 10 and inner core 11 are communicated with the suction device (not shown) as particulate outlet 12.
It is to constitute like this that above-mentioned eddy current flows into structure 9, that is, and and on shunting tube 13, side from being of the outside that the is positioned at above-mentioned urceolus 10 cylindric diffluence room 14 that forms of concentric shape, tangentially give prominence to and installing dusty gas inflow pipe 15, simultaneously, be formed with dusty gas inflow entrance 17.This dusty gas inflow entrance 17 have outstanding be arranged at above-mentioned cylindric diffluence room 14 bottoms and be vortex shape to internal diameter direction from the inboard of shunting tube 13 tilt that (the eddy current direction is a plurality of (being six) shunting wing 16,16 a) the embodiment ...In addition, by dusty gas inflow pipe 15, (12～20m/s) supply with and contain by the gas of classification particle according to the transporting velocity of defined.
The cyclone type dust collecting apparatus of said structure is supplied with by dusty gas inflow pipe 15 and is contained by the gas of classification particle, separates the gas that reclaims coarse grain and contain particulate with particulate outlet 12 by coarse grain outlet 3 again.By changing this burble point, can become via 12 cyclone type dust collecting apparatus that reclaim gas of particulate outlet.
Structure according to above-mentioned cyclone type dust collecting apparatus, flow into the dusty gas of cylindric diffluence room 14 because eddy current flows into the shunting wing 16,16 of structure 9 via dusty gas inflow pipe 15 ... the eddy current that flows to direction of arrow a of effect and becoming and to grading room 4 ejections, and sedimentation gradually (the sedimentation direction is F1).Yet, owing in above-mentioned grading room 4, form the tube passage that the tubular exhaust passage that is made of urceolus 10 and inner core 11 and inner core 11 constitute according to multiple exhaust structure 8, and area of section is divided into two again, so, the impartial centripetal force to center C L that parallel gas flow velocity (the flow velocity direction is F2) by the equalization that attracted by above-mentioned two passages produces will play a role, and the particle that contains in the gas falls to centrifugal force F3 that eddy current produced and the difference of centripetal force F2 and the resultant direction F of above-mentioned settling capacity F1.
In above-mentioned cyclone type dust collecting apparatus, give prominence to being provided with bottom that is positioned at above-mentioned cylindric diffluence room 14 and a plurality of shunting wings 16,16 that are the vortex shape inclination from the inboard of shunting tube 13 to internal diameter direction ...The above-mentioned shunting wing 16,16 ... though there is the dusty gas that to flow into diffluence room 4 from cylindric diffluence room 14 that its eddy current is carried out the effect of rectification, the not effect that its eddy current is quickened.
Therefore, the objective of the invention is to rectification and quicken flow into cylindric diffluence room flows into the dusty gas of separation chamber again from pipe shape diffluence room eddy current from the dusty gas inflow pipe, make dust concentrate on the peripheral part of separation chamber by booster action in the centrifugal force of dust, from the peace and quiet air that does not have dust of peace and quiet air discharge pipe discharge separation chamber central part, to improve the function of control of dust.
For achieving the above object, the cyclone type dust collecting apparatus that the present invention relates to comprises: top is cylinder 20a, and the bottom is inverted cone tube 20b, and the lower end of above-mentioned inverted cone tube 20b is the separation chamber 20 of dust outlet 20c; Be the peace and quiet air discharge pipe 21 that concentric shape is provided with the axle center on 20 tops, above-mentioned separation chamber; With on the upper wall 20d of above-mentioned separation chamber 20, be the opening 20e cylindric diffluence room 22 that be connected, that have upper wall 22a that concentric shape runs through setting with the axle center; In order to make dust laden air flow into and be connected dusty gas inflow pipe 23 in the above-mentioned cylindric diffluence room 22 from tangential direction; With the inboard of the upper wall 20d of above-mentioned separation chamber 20 with run through the inner portion that the opening 20e that is arranged on the upper wall leaves certain desirable interval D, around above-mentioned peace and quiet air discharge pipe 21, plate 24a is set, on this plate 24a, is provided with the eddy current rectification accelerating structure 24 that quickens ditch 24b for the eddy current rectification of the dust laden air that will flow into from above-mentioned opening 20e and a plurality of eddy current rectifications of quickening.
