Description
Technical field
The utility model relates to a kind of rotor of powder separator, particularly a kind of Packed rotor of powder separator is set.
Background technology
Traditional dynamic powder concentrator generally includes by housing parts, drive part, lubricated part and rotating part and forms, wherein, the more employing of rotating part be mechanical labyrinth movable sealing form, adopt such hermetically-sealed construction, sealed precision mainly relies on labyrinth clearance to guarantee, in traditional dynamic powder concentrator system, normal sealing to occur bad, seals easy to wearly, causes and select powder fineness not high, it is unreasonable that grain is joined grade degree, phenomenons such as material runs thick, and grinding efficiency is low are difficult to satisfy the requirement to product quality; And in the powder concentrator that adopts simple labyrinth seal form, because the entrance and exit two ends Negative Pressure Difference of seal channel is bigger, enter the power that move in the still oriented exit of dust of seal channel inside, be difficult to thorough sealing, usually cause the inner dust of seal clearance to cause sealing not thorough, phenomenons such as the easy wearing and tearing of sealing partition because of suction function.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of sealing effectiveness better rotor of powder separator.
The technical solution adopted in the utility model is such: a kind of rotor of powder separator, comprise the upper plate that is provided with air outlet, and the lower shoe that is provided with installing hole, the upper plate center is provided with air outlet, installing hole is coaxial with air outlet, be provided with rotor blade between upper plate and the lower shoe, described rotor blade one end is fixedlyed connected with lower shoe, the described rotor blade other end runs through upper plate, contiguous air-out oral-lateral is provided with sealing ring on the described upper plate, described air outlet is provided with seal groove, and described sealing ring cooperates with seal groove.
Described rotor blade comprises a plurality of blades, and described blade is that center array is provided with on the lower shoe with the air outlet axis, and the described blade other end runs through upper plate, and described blade is parallel with the air outlet axis;
Described sealing ring cooperates with seal groove;
The arranged outside of described sealing ring and seal groove cooperation position has radial rotor blade extension.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: owing to adopted this sealing, and the sealing import department be provided with rotor blade, form the bigger outside wind energy power of sweeping during running, make the dusty gas at seal place have the trend of stronger outside motion, avoided because the inner dust in the bigger gap that causes of Negative Pressure Difference at the import of sealing, outlet two ends is piled up, the wearing and tearing that slowed down the sealing partition make sealing effectiveness better.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figures 1 to 4, the utility model rotor of powder separator comprises upper plate 4 and the lower shoe 6 that is parallel to each other, upper and lower base plate cross section is all rounded, wherein, lower shoe 6 is near the drive end of powder concentrator when work, and lower shoe 6 centers are provided with in order to the installing hole of driving shaft to be installed, the remainder of lower shoe 6 is the entity patty plate of sealing, when work, upper plate 4 one sides are the air side, and the center of upper plate 4 is provided with the bigger air outlet in aperture 1;
On, be evenly equipped with the bearing of trend rotor blade vertical 5 between following two base plates with base plate, rotor blade 5 is combined by a plurality of separate blades, the quantity of rotor blade 5, and the interval between each rotor blade 5 is provided with as required, and around last, on the isometrical circle of lower shoe a circle is set, after assembling is finished, form the cage structure that a circle rotor blade 5 is arranged with plectane central shaft array around the parallel and plectane of two plectanes, its overall structure is mouse cage shape common in the life, the parallel disc of mouse cage both sides be equal in the utility model on, lower shoe is equivalent to rotor blade 5 in the utility model in order to a circle cylinder that connects two parallel discs in the mouse cage.
Rotor blade 5 is fixedlyed connected with adjacent with it lower shoe 6 plate faces, rotor blade 5 runs through upper plate 4, the upper plate 4 of adjacent rotor central shaft one side is provided with sealing ring 8, air outlet 1 is provided with seal groove 9 accordingly, sealing ring 8 cooperates with seal groove 9, form sealing, rotor blade 5 fits tightly fixing away from rotor center axle one side and upper plate 4, rotor blade 5 is after running through upper plate 4, continue to extend a segment distance downwards, promptly two near surfaces at upper plate 4 are provided with rotor blade 5, be different from that upper plate 4 only is provided with rotor blade 5 in the conventional art between two base plates, the utility model rotor 2 when rotated, the rotor blade 5 that is positioned at 4 two near surfaces of upper plate all produces stronger centrifugal wind-force, the sealing that sealing ring 8 and seal groove 9 are formed, being sealed into the air port is sealing ring 8 arranged outside blade extensions, produce strong outside centrifugal flow during running, near the dust foreign material making in the interval etc. all are difficult to enter between seal area, and are thick to prevent that material from running.Rotor 2 integral body are positioned at volute 3, for the intensity that guarantees rotor 2 and stable rotation function etc., strengthening part 7, i.e. reinforcement are arranged in the middle of the rotor 2.Sealing ring 8 has radial rotor blade extension with the arranged outside of seal groove 9 cooperation positions.
Operation principle of the present utility model is: during work, band material dusty gas forms eddy current in powder concentrator volute 3, and rotor 2 rotations produce outside centripetal force, and the powder concentrator negative-pressure operation aspirates dusty gas to rotor 2 centers.Under the acting in conjunction of the outside centripetal force of the suction force effect of negative pressure and rotor 2, it is bigger that the material that granularity is bigger in the dusty gas is subjected to outside centrifugal force, outwards thrown and be thrown to volute 3 wall near zones, because rim effect, movement velocity is more and more slower, finally deposit, outside powder concentrator meal feedback outlet, discharge powder concentrator.And the less qualified material of granularity in the dusty gas, it is bigger to be subjected to inside negative-pressure sucking, is drawn onto rotor 2 centers, discharges powder concentrator from air outlet 1, enters the dust collection device of next step, is collected and gets off to become finished product.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
