Abstract

The utility model relates to the material screening machinery, in particular to a cyclone powder selector, and comprises a cyclone separating cylinder, a plurality of powder selecting cylinders with multi-stage multi-path structures, and a circulating air duct system. The utility model is characterized in that a tangential or volute shape air inlet is mounted at side face of a cylinder body of each powder selecting cylinder, a rotor which is driven by a central rotation shaft is arranged in an intra-cavity of the cylinder body, the rotor is taken in a tumble type which is formed by a connecting disc which is arranged on the bottom, a spillage disc which is arranged on the top, and a plurality of grids which are vertically connected between the connecting disc and the spillage disc, and a wind-guiding pipe is arranged at the center of the spillage disc and is communicated with an air exhaust pipe, a blanking pipe is further mounted on the upper end of the cylinder body and is arranged above the spillage disc, a striker plate is also fixed on the periphery of the spillage disc, and a guide blade is arranged between the side wall of the cylinder body and the rotor. The cyclone powder selector of the utility model has the advantages of good dispersity of materials, fully complete grading, high accuracy of grading, high efficiency of powder selecting, simple structure, and convenient adjustment when in use.

Description

Cyclone type powder sorting machine

Technical field

The utility model relates to material screening machinery, particularly a kind of cyclone type powder sorting machine.

Background technology

Cyclone type powder sorting machine is mainly used in the classification and sorting of granular material, and existing equipment mainly exists defectives such as classification is insufficient, effectiveness of classification is low, grinding efficiency is low.Patent documentation CN2254011 discloses a kind of cyclone type powder sorting machine, what it comprised cyclone separating tube, multistage multichannel structure selects powder tube and circulation air path system, its grinding efficiency improves to some extent, but still it is not high, simultaneously as its core select the powder barrel structure unreasonable, still exist material bad dispersibility, classification is insufficient, the efficiency of separation is low defective.

Summary of the invention

Technical problem to be solved in the utility model is, the defective of prior art is improved, provide a kind of material good dispersion, classification fully fully, effectiveness of classification is high, grinding efficiency is high, simple in structure, easy to adjust cyclone type powder sorting machine.

Cyclone type powder sorting machine of the present utility model includes cyclone separating tube, the a plurality of powder tube and circulation air path systems of selecting of multistage multichannel structure, described each select the powder tube to include a cylindrical shell, the air inlet of tangential or scroll casing shape is installed in the cylindrical shell side, a rotor that is driven by central rotating shaft is arranged in the housing inner chamber, described rotor is by the tie-plate of bottom, the spreading disk at top and many grizzly bars that vertically are connected between them constitute, described grizzly bar is evenly arranged along the tie-plate excircle, make whole rotor constitute a rotating cage shape, at the spreading disk center guide duct is installed, guide duct communicates with the exhaust column that is installed in the cylindrical shell upper end, the cylindrical shell upper end also is equipped with tremie pipe, it is positioned at the spreading disk top, also be fixed with the striker plate of one section tubular in the spreading disk periphery, be evenly distributed with the guide vane of vertical installation between cylinder lateral wall and rotor along circumference, the guide direction of guide vane is tangential.

The utility model makes air intake form the eddy airstream that rotates in a circumferential direction owing to settled tangential guide vane in cylindrical shell, and air-flow and material attaching space are big, and time of contact is long, thereby material sorting condition is good, and classification is more complete, efficiency of separation height; Simultaneously, owing to adopt the rotating cage type structure, not only easy to adjust by changing the finish fineness that the rotating shaft rotating speed just can change sorting, and variation is sensitive, precision is high.

Fig. 2 is vertical sectional structure chart that the utility model selects the powder tube;

Fig. 3 is the plan structure schematic diagram of Fig. 2.

The specific embodiment

As shown in Figure 1, this cyclone type powder sorting machine includes a plurality of powder tube 2 and circulation air path systems 3 of selecting of cyclone separating tube 1, multistage multichannel structure.Select structure such as Fig. 2, shown in Figure 3 of powder tube, it includes a cylindrical shell 4, the air inlet 5 that tangential or scroll casing shape are arranged in the cylindrical shell side, a rotor that is driven by central rotating shaft 6 is arranged in the housing inner chamber, rotor has tangential guide vane 14 by the rotating cage shape that tie-plate 7, spreading disk 8 and grizzly bar 9 constitute between cylinder lateral wall and the rotor.In the course of work, material enters cylindrical shell by tremie pipe 12, thrown to its peripheral striker plate 13 by spreading disk 8, material is broken up the back by bump and is fallen, because the air intake of below forms eddy airstream under the effect of guide vane, material and air-flow mix suspending and fully classification, thinner material powder passes above-mentioned grizzly bar 9 and enters internal rotor, extract and be transported to cyclone separating tube 1 by guide duct 10 and exhaust column 11, and thicker material powder drains into next stage by the hopper 15 of cylindrical shell bottom and selects powder tube 2 to carry out sorting once more, or enters the meal storehouse.

Claims

1, a kind of cyclone type powder sorting machine, include cyclone separating tube (1), the a plurality of powder tube (2) and circulation air path systems (3) of selecting of multistage multichannel structure, it is characterized in that: each selects powder tube (2) to include a cylindrical shell (4), the air inlet (5) that tangential or scroll casing shape are arranged in the cylindrical shell side, a rotor that is driven by central rotating shaft (6) is arranged in cylinder lumen, described rotor is by the tie-plate (7) of bottom, spreading disk at top (8) and the many grizzly bars (9) that vertically are connected between them constitute, described grizzly bar is evenly arranged along the tie-plate excircle, make whole rotor constitute a rotating cage shape, at spreading disk (8) center guide duct (10) is installed, guide duct communicates with the exhaust column (11) that is installed in the cylindrical shell upper end, the cylindrical shell upper end also is equipped with tremie pipe (12), it is positioned at the spreading disk top, at the peripheral striker plate (13) that also is fixed with one section tubular of spreading disk (8), between cylinder lateral wall and rotor, be evenly distributed with the guide vane (14) of vertical installation along circumference.
