Embodiment one
Shown in Fig. 2-3; The utility model cyclone separator comprises the first cyclonic separation unit and the second cyclonic separation unit; Air-flow gets into the first cyclonic separation unit and carries out the separation first time, and the air-flow 38 after separating for the first time gets into the second cyclonic separation unit and carries out the separation second time; The said second cyclonic separation unit has Whirlwind barrel 41, and the sidewall of Whirlwind barrel is provided with air intake 411, and a side 411a of air inlet is connected with the inwall 412 of Whirlwind barrel.It is emphasized that above-mentioned being connected is meant that the inwall of a side 411a and Whirlwind barrel of air inlet is tangent or tangent basically, make the air-flow that gets into Whirlwind barrel to move as rotation direction along the inwall of Whirlwind barrel 412.One side of air inlet and inwall is tangent or when tangent basically, the angle of the radially radius of a side of this air inlet and the Whirlwind barrel of connection is 70 °～120 °.
The opposite side 411b of the air intake 411 of Whirlwind barrel 41 is provided with guiding rib 40, and this guiding rib 40 is convexly equipped with to the inner chamber of Whirlwind barrel along the inwall 412 of Whirlwind barrel.Preferably, guiding rib 40 is convexly equipped with to the direction that a side that is connected with the inwall of Whirlwind barrel parallels along the inwall 412 of Whirlwind barrel.The benefit that guiding rib 40 is set like this is: because this guiding rib 40 is convexly equipped with a segment distance along Whirlwind barrel inwall 412 to the inner chamber of whirlwind tube; Thereby the air-flow that gets into air intake 411 also can move in a circle near a side of guiding rib 40; Can directly be drawn into the air outlet of Whirlwind barrel center very soon, can be made that basically the air-flow of Whirlwind barrel all moves in a circle; Because the barrier effect of guiding rib 40, can make the air-flow that moves in a circle along Whirlwind barrel inwall 412 inwalls rapidly under the screw; Because the barrier effect of guiding rib 40, the dust in the air-flow is run into guiding rib 40, because unexpected stall, dust directly falls along guiding rib 40.Therefore, the effect of guiding rib 40 have following some: the standard guidance air-flow, promptly the air-flow near guiding rib 40 also can move in a circle, and can directly be drawn into the air outlet of Whirlwind barrel center very soon; The air-flow that makes circular motion is rapidly under the screw; The dust of running into guiding rib 40 directly falls.
Because guiding rib 40 is arranged on the inboard of Whirlwind barrel inwall 412; Also promptly be arranged on the inner chamber of Whirlwind barrel; Need not the extra guiding side of widening that is provided with at air inlet place, the outside of Whirlwind barrel inwall; Can greatly reduce the cross-sectional area of secondary cyclonic separation unit, thus the volume of bigger minimizing whirlwind staving, the manufacturing cost of reduction dust catcher.
Further, guiding rib 40 is extended by the top edge of air inlet 411 lower limb to air inlet, and guiding rib 40 along the lower limb of air inlet 411 again to extending below the segment distance, this distance is less than or equal to 1/5 of air inlet height.
Further; Guiding rib 40 reduces to the distance that the inner chamber of Whirlwind barrel 41 is convexly equipped with from top to bottom gradually; Guiding rib 40 is unsuitable long to the distance that the central shaft of Whirlwind barrel 41 is convexly equipped with, and its distance is less than or equal to 1/3 of Whirlwind barrel 41 respective heights cross-sectional diameters.
The number that the second cyclonic separation unit has Whirlwind barrel 41 is 6～12, and Whirlwind barrel 41 is evenly distributed around the central shaft of the second cyclonic separation unit.
Further specify the structure and the course of work of cyclone separator below in conjunction with accompanying drawing.
Shown in Fig. 4-5, the utility model cyclone separator comprises that first cyclone unit and second revolves the cyclonic separation unit.First cyclone unit comprises dirt bucket 28 and mesh filter 23.Dirt bucket 28 is provided with first air inlet 281, and this dirt bucket 28 is used to carry out the gas solid separation between the fouls such as gas and particle, and its bottom is used to collect foul; Mesh filter 23 is provided with pore 231, a plurality of through holes that this pore 231 is provided with for mesh filter 23.The second cyclonic separation unit is positioned at the downstream of the first cyclonic separation unit; The second cyclonic separation unit comprises separator 36 and is connected bucket 25; Separator 3 comprises a plurality of Whirlwind barrels 41, Whirlwind barrel 41 upper and lower end openings, and the below of separator 36 is provided with and connects bucket seal cover 37; Offer circular hole on the connection bucket seal cover 37, the quantity that connects circular hole on the bucket seal cover 37 is identical with the quantity of Whirlwind barrel 41.
Circularhole diameter on the connection bucket seal cover 37 is more than or equal to Whirlwind barrel 41 lower end diameter, less than Whirlwind barrel 41 upper end diameter; The circular hole of Whirlwind barrel 41 through connecting bucket seal cover 37 with is connected bucket 25 and is connected, connect barrel seal cover 37 and be connected barrels 25 and be tightly connected.
The air-flow 38 of foul such as entrained dirt, particle gets into dirt bucket 28 along first air inlet 281 on the dirt bucket 28, and air-flow rotates in dirt bucket 28, carries out the gas solid separation first time, utilizes centrifugal force that bulky grain foul and part dust are separated from air-flow.Further, the dust retaining ring 26 that mesh filter 23 is provided with can effectively prevent the secondary dust, and the foul after the gas solid separation falls into the bottom of dirt bucket 28.For ensureing the separative efficiency of cyclone separator, cyclone separator is provided with different sealing rings at diverse location, such as: be arranged on the dirt bucket bottom sealing ring 29 between dirt bucket 28 and the dirt bucket bottom 30, its leakage ash that effectively prevents to lose heart; Be arranged on the interior dirt bucket sealing ring 27 between dirt bucket 28 and the mesh filter 23, it prevents that effectively the air-flow that is arranged in dirt bucket 28 from directly getting into separator 36 without the pore on the mesh filter 231.The air-flow 38 of gas solid separation moves upward along the outer wall that connects bucket 25 through the pore 231 on the mesh filter for the first time, gets into the second cyclonic separation unit.
The inwall of air-flow 38 through mesh filter 23 moves upward with slit between the outer wall that is connected bucket 25; Arrive the port place that connects bucket 25; Move upward along the slit between the inwall of the inwall of the outer wall of separator 36, taper hole lid and mesh filter 23 again; Air inlet 411 from Whirlwind barrel 41 directly gets in the Whirlwind barrel 41; Air-flow utilizes the separation of centrifugal force, and isolated foul falls into through Whirlwind barrel 41 lower ending openings and connects bucket 25, and the air communication of the process gas solid separation second time is crossed the open upper end of Whirlwind barrel 41 and discharged.The separator sealing ring 32 that is positioned on the separator 36 seals the upper end of separator 36 and taper hole lid, has effectively to prevent the effect of losing heart.Filter pad 33 is used to filter the air-flow through after Whirlwind barrel 41 separation for the second time between taper hole lid and dirt bucket loam cake 19, further filters the fine dust that is mingled with, and guarantees that it is clean discharging air-flow.Dirt bucket loam cake sealing ring 20 is arranged between dirt bucket loam cake 19 and the taper hole lid and seals, and effectively prevents the effect of losing heart.Dirt bucket loam cake 19 is provided with operation dirt bucket release-push 31 and elastomeric element 17, and operation dirt bucket release-push 31 can take out and lay dirt bucket 28 from cyclone separator easily; Elastomeric element 17 guarantees to reset after 31 operations of dirt bucket release-push are accomplished.
