At first, use Figure 10, Figure 12, Figure 16 that the structure of secondary cyclone separator 20 is described.
This secondary discharge pipe 26 is shown in figure 12, and the outside in secondary rotating room 22 constitutes with the mode that bends to approximate right angle.In addition, like Figure 10 and shown in Figure 16, the downstream of the bend of secondary discharge pipe 26 is extended to the direction 90 ° the position of advancing in the direction of rotation of above-mentioned dust laden air in 21 position contacting that enter the mouth from secondary rotating room 22 and Secondary Flow and is provided with.
In addition, secondary discharge pipe 26 makes secondary rotating room 22 roughly consistent with its axle, in secondary rotating room 22, is provided with highlightedly, on the diapire of its protuberance, has secondary outlet 25.
In addition, the sidewall of secondary rotating room 22 is made up of the cylindrical portion 22b of general cylindrical shape shape and the conus portion 22a of conical shaped shape.In addition, a part of opening and secondary peristome 23 that forms and the secondary dust storage chamber 24 that is communicated with secondary rotating room 22 via secondary peristome 23 that have conus portion 22a.
Summary to the action of secondary cyclone separator 20 describes.
When secondary cyclone separator 20 via discharge pipe 16 when Secondary Flow inlet 21 is introduced dust laden airs; Dust laden air becomes swirling eddy owing to the sidewall along secondary rotating room 22 flows into; Form the free vortex of the standard zone of near the forced vortex zone of central shaft and its outer circumferential side; Simultaneously, flow downward owing to this path structure and gravity.At this moment; Because centrifugal action is in dust; In cyclone separator 10, be not pushed on the inwall of secondary rotating room 22 and separated from sucking gas by the rubbish of catching fully; After below along with the rotating flow entering secondary rotating room 22 that descends, be trapped in the secondary dust storage chamber 24 via secondary peristome 23.Removed of the central shaft rising of the air of rubbish, be discharged from from secondary outlet 25 along secondary rotating room 22.The air of discharging from secondary outlet 25 is directed to exhaust wind path 51 through secondary discharge pipe 26.
Here, the mobile of air in the secondary discharge pipe 26 that as above-mentioned, constitutes described.Shown in figure 12, when the wind path in the secondary discharge pipe 26 was generally perpendicularly crooked, the bending radius of air stream (dotted line) of inboard that is positioned at this bending wind path was smaller, receives impedance loss.On the other hand, because it is bigger to be positioned at the bending radius of air stream (solid line) of inboard of crooked wind path,, do not receive impedance loss so it is smooth-going to flow.Therefore, very fast from the velocity ratio of rotating room's 12 inhaled airs stream, its power is strong.The result is, the distribution of the flow velocity of secondary outlet 26, is that the distribution of attraction produces strong and weak.
Therefore; The position relation of the bending direction of the secondary discharge pipe 26 through forming above-mentioned that kind and Secondary Flow inlet 22; Can be not the part a little less than the velocity flow profile of secondary outlet 15 be configured near the Secondary Flow inlet 21, can suppresses rotate secondary rotating part 22 in before from Secondary Flow 21 leaked-in airs that enter the mouth that horse back is inhaled into secondary outlet 25.Thus, make towards the mobile enhancing of direction of rotation and can capture rubbish reliably.Relative with it; Under near the strong part of distribution with the flow velocity of secondary outlet 25 is configured in Secondary Flow inlet 21 the situation, the part of air-flow is 22 inward turnings then directly from 25 discharges of secondary outlet in the secondary rotating room not, and; Generation is towards the reciprocal air-flow of direction of rotation; Therefore, the centrifugal force that acts on rubbish reduces, and is difficult to capture rubbish.
In addition; In order to obtain the effect of above-mentioned that kind, as long as it is strong and weak that velocity flow profile is produced, therefore; The 5th page the 18th that the invention is not restricted to this specification is walked to the 6th page of the 7th structure shown in the row, for example also can not make the angle of bend approximate vertical of secondary discharge pipe 26.
In addition; For the power of the velocity flow profile of further clear and definite secondary outlet 25, can make characteristic length (D) 25 times below of the crooked distance (X) that bends away initial point (the some A Figure 12) of from secondary outlet 25 to the secondary discharge pipe 26 beginnings for the cross section of the wind path in the secondary discharge pipe 25.In addition, the cross sectional shape at blast pipe wind path 16 is that characteristic length (D) is this circular diameter under the situation of circle.
Following situation is known: general; Under the situation of simple tube fluid,, arrive the boundary layer along tube wall when fashionable with the same velocity flow from tube inlet; When its thickness increased and arrive central part, the VELOCITY DISTRIBUTION in the pipe became necessarily (parabolic velocity distribution etc.).Arrive this fully flourishing interval before of flowing and be called between the runway, its length is called run-up distance l, and is general under the situation of sinuous flow, l/D＞25～40 (D is the characteristic length of tube section).That is, the velocity flow profile in 1/D＞25～40 and the pipe is certain.
Because secondary cyclone separator 20 in the regional use of high wind speed, is the sinuous flow state so it flows usually, is suitable for using above-mentioned relational expression,, can further strengthen towards flowing of direction of rotation also capturing rubbish reliably if satisfy above-mentioned size relationship.In addition, through forming distance X, has the effect that can make 20 miniaturizations of secondary cyclone separator.
In addition; In the wind path in secondary discharge pipe 26; If the upstream side that bend away initial point crooked in beginning is provided with filter; Then owing to the pressure loss of filter, the air-flow in the wind path in the secondary discharge pipe 26 of the upstream side of filter is by rectification, and the power of the velocity flow profile of secondary outlet 25 is suppressed.
Therefore, in the present invention, filter is not set between the initial point at inferior outlet 25 and crooked the bending away of beginning.Thus, the power of the velocity flow profile of secondary outlet 25 manifests significantly, can further strengthen towards flowing of direction of rotation also to capture rubbish reliably.
Next, use Figure 11, Figure 14, Figure 15, Figure 16 and Figure 17 that the structure of a cyclone separator 10 is described.
A cyclone separator 10 has from sucking wind path 49 to be introduced an inflow entrance 11 of dust laden air, makes from a rotating room 12 of the dust laden air rotation of inflow entrance 11 importings on the tangential direction through an inflow entrance 11 is connected in roughly; Make from the suction gas rotation of inflow entrance 11 inflows and after with dust separation, should suck gas and discharge from an outlet 15.In addition, have discharge pipe 16 one time, this discharge pipe 16 will guide to secondary cyclone separator 20 from the discharge gas of this outlet 15.
This discharge pipe 16 is shown in figure 17, and the outside a rotating room 12 constitutes with the mode that bends to approximate right angle.In addition, like Figure 14 and shown in Figure 16, the downstream of the bend of a discharge pipe 16 is provided with extending to the direction 90 ° the position of advancing in the direction of rotation of above-mentioned dust laden air from rotating room 12 and inflow entrance 11 position contacting.
In addition, shown in figure 15, the downstream of the bend of a discharge pipe 16 is provided with respect to extending on the direction in the scope on 45 ° in both sides on the plane of the axle of a central point that connects 0 peristome 113 and a rotating room 12.
In addition; One time discharge pipe 16 makes a rotating room 12 roughly consistent with its axle; And in a rotating room 12, be provided with highlightedly; The sidewall of its protuberance is made up of with the cone 15a with conical shaped shape of a plurality of minute apertures the cylinder 15b of the general cylindrical shape shape with a plurality of minute apertures, constitutes outlet 15 through this minute aperture.
In addition, the sidewall of a rotating room 12 is made up of the cylindrical portion 12b of general cylindrical shape shape and the conus portion 12a of conical shaped shape.In addition, has a part of opening of cylindrical portion 12b and a part of opening of 0 peristome 113 forming, conus portion 12a and a peristome 13 forming, 0 dust storage chamber 114 that is communicated with rotating room 12 via 0 peristome 113, a dust storage chamber 14 being communicated with rotating room 12 via peristome 13.In addition, 0 peristome 113 is formed at the position lower than inflow entrance 11.
About the action of a cyclone separator 10, its summary is described.
When cyclone separator 10 via sucking wind path 49 when an inflow entrance 11 is introduced dust laden airs; Dust laden air flows into along the sidewall of a rotating room 12; Therefore become swirling eddy; In the free vortex of the standard zone of near the forced vortex zone forming central shaft and its outer circumferential side, owing to its path configuration and gravity flow downward.At this moment; Because centrifugal action is in dust; Therefore; The rubbish that for example size of hair, candy paper, sand (bigger sand) etc. and proportion are all bigger (below, be called " rubbish A ") is pushed on the inwall of a rotating room 12 and separates from sucking gas, is captured and is deposited in 0 dust storage chamber 114 via 0 peristome 113.In addition, the dust that is left advances to the below of a rotating room 12 along with the rotating flow that descends.Thus; Gently and easily follow air-flow and bulky cotton rubbish and tiny sand rubbish (below, be called " rubbish B ") and be sent in dust storage chamber 14 via peristome 13, and then; Arrived in the top of a dust storage chamber 14 through blast, piled up there and be compressed.Removed of the central shaft rising of the air of rubbish A and rubbish B, and be discharged from from an outlet 15 along a rotating room 12.The secondary cyclone separator of explanation after the air that is discharged from from outlet 15 is directed into through a discharge pipe 16.
Through constituting discharge pipe 16 as described above agley one time, through with the above-mentioned identical principle of having explained of principle, the distribution of the flow velocity of an outlet 15, be that the distribution of attraction produces strong and weakly.
Therefore; Bending direction through forming an above-mentioned discharge pipe 16 and the position of an inflow entrance 11 relation; Shown in figure 17, can be not the part a little less than the distribution of the flow velocity of an outlet 15 be configured near inflow entrance 11, can suppress following situation; That is,, inflow entrance 11 leaked-in airs sucked outlet 15 at once one time before rotating in a rotating part 12.Thus, can strengthen flowing and capture rubbish reliably to direction of rotation.Relative with it; Under the strong part of distribution with the flow velocity of an outlet 15 was disposed near situation the inflow entrance 11, the part of air-flow was rotating room's 12 inward turnings then directly discharge from an outlet 15, and; Generation is towards the reciprocal air-flow of direction of rotation; Therefore, the centrifugal force that acts on rubbish reduces, and is difficult to capture rubbish.
In addition; Concern through the bending direction of an above-mentioned discharge pipe 16 and the position of 0 peristome 113; The weak part of the velocity flow profile of an outlet 15 is configured near 0 peristome 113, and the part that attraction is strong is not configured near 0 peristome 113, therefore; Inhibition is from outlet 15 inhalation power to the rubbish A that 0 dust storage chamber 114, separates, and can separating property be improved the amount that has suppressed.
In addition, in order to obtain the effect shown in above-mentioned, as long as it is strong and weak at outlet 15 velocity flow profile to be produced, therefore, the present invention is not limited only to the structure shown in the present embodiment, and for example, the angle of bend of a discharge pipe 16 can not be an approximate vertical also.
In addition, the effect that obtains through the position relation that constitutes effect that discharge pipe 16 obtains and the bending direction through a discharge pipe 16 and 0 peristome 113 agley is separate effect.That is, the effect that the bending direction of an above-mentioned discharge pipe 16 and the position of 0 peristome 113 relation are produced does not rely on the position relation of the bending direction and an inflow entrance 11 of an above-mentioned discharge pipe 16, vice versa.
In addition; As stated, form outlet 15 one time, can obtain attraction that suppresses axial and the effect that increases the revolving force that acts on rubbish through minute aperture by the sidewall that is arranged at a discharge pipe 16; In addition; Shown in figure 14, in discharge pipe 16, also can form an outlet 15 removing the zone outside near the part the inflow entrance 11.
Thus; Can suppress axial attraction and increase the revolving force that acts on rubbish; Simultaneously; Can suppress directly to be sucked outlet 15 one time, and further strengthen the centrifugal force that acts on rubbish towards the mobile and raising of direction of rotation, can further improve the capture performance from the suction gas of inflow entrance 11 inflows.
In addition, like Figure 11 and shown in Figure 13, in discharge pipe 16, also can form an outlet 15 in the zone except near the part 0 peristome 113.
Thus; When suppressing axial attraction and the revolving force that acts on rubbish increased; The attraction from an outlet 15 that acts on the rubbish A that flies into 0 dust storage chamber 114 via 0 peristome 113 is suppressed; Therefore, can be reliably rubbish A be captured in 0 dust storage chamber 114.Relative with it; In discharge pipe 16, an outlet 15 is being arranged under near the situation in 0 zone the peristome 113, from the attraction of an outlet 15 rubbish A is produced big effect; Therefore; Rubbish A is difficult to be trapped in 0 dust storage chamber 114, and, temporarily be trapped in dispersing once more of 0 rubbish A in the dust storage chamber 114 and also take place easily.
In addition, shown in figure 13, at least a portion of the conical shaped shape face of cone 15a axially on height and position, be in 0 peristome 113 axially on the opening scope in mode dispose.
Thus; Suppress axial inhalation power and increase act on the revolving force of rubbish in; Can guarantee the distance of 0 peristome 113 and outlet 15; Inhibition acts on the attraction of the rubbish A that 0 dust storage chamber 114, separates from outlet 15 via 0 peristome 113, can in 0 dust storage chamber 114, capture rubbish A reliably.
In addition; In a cyclone separator 10 of the reversible type shown in this embodiment; Discharge pipe 16 becomes the outstanding structure from the top of a rotating room 12, is suppressed from the attraction to rubbish A of an outlet 15, therefore; Even 0 peristome 113 is arranged on the height near cone 15a, also can be reliably rubbish A be captured in 0 dust storage chamber 114.Therefore, the degree of depth of 0 dust storage chamber 114 can be deepened, and dispersing once more and improve and capturing performance of rubbish A can be further suppressed.
In addition, rotate and arrive the air-flow counter-rotating of the below of a rotating room 12, can the air communication that rise in the central authorities of a rotating room 12 be crossed cone 15a and introduce smooth-goingly, therefore, swirling eddy is not disorderly, can improve the capture performance.In addition,, therefore, has following advantage: when the isometric thread rubbish of hair curls, move along the top orientation of circular cone, can easily be removed through making this rubbish in a discharge pipe 16 because cone 15a is the conical shaped shape.
In addition; Like Figure 11 and shown in Figure 13; The axial altitude range of an inflow entrance 11 is configured to be positioned at the axial altitude range of cylinder 15b, and, the axial height and position of the big end of cone 15a is positioned at outside the axial opening scope of 0 peristome 113.
Thus, the air-flow that gets into from inflow entrance 11 can rotate smooth-goingly, and therefore, the centrifugal force that acts on rubbish increases, and can improve the capture performance.In addition; In the axial opening scope of 0 peristome 113; Only dispose cone 15a, therefore, can guarantee the distance of 0 peristome 113 and an outlet 15 more reliably; Inhibition is flown to the attraction of 0 rubbish A in the dust storage chamber 114 from acting on of an outlet 15, can improve the capture performance.
In addition; Through a conus portion 12a, a peristome 13 and a dust storage chamber 14 are set as above-mentioned, can be captured in 0 dust storage chamber 114 not by the rubbish B (the comparatively speaking little and little rubbish of effect air drag of surface area) that captures fully through a dust storage chamber 14.In addition, in conus portion 12a, the radius of turn of swirling eddy reduces gradually; Has the effect that improves the centrifugal force that acts on rubbish; Rotate and arrive the air-flow counter-rotating of the below of a rotating room 12, can be introduced in the air-flow of central authorities' rising of a rotating room 12 through cone 15a, therefore more smooth-goingly; Swirling eddy is not disorderly, can improve the capture performance.That is,, can be more reliably rubbish B be captured in dust storage chamber 14 through the combination of an above-mentioned conus portion 12a and cone 15a.
In addition, also can be shown in figure 11 suchly constitute, that is, the angle of inclination with respect to the axis of centres of a rotating room 12 of a conus portion 12a is substantially equal to or below the angle of inclination of cone 15a with respect to the axis of centres of a rotating room 12.
