Abstract
The utility model discloses a classifying device for micro-powder material which mainly comprises a classifying room 1, a separated cone 3 at the lower part of the classifying room and a feeding and discharging cone 4. A dynamic shaft component 2, a classifying wheel 10 and a micro-powder discharge tube 9 are equipped in the classifying room. A feeding tube 7 and an air inlet pipe 6 are equipped on the feeding and discharging cone 4. The classifying device for micro-powder material is characterized in that a compressed air inlet 13 and an air sealing room are communicated on the outer shell of the dynamic shaft component 2. The air sealing room 15 is communicated with an air sealing channel at one side of the classifying wheel 10. The major advantage is that the device can be connected to the existing micro-powder equipment and separates out the needed micro-powder material. The classifying device for micro-powder material is provided with excellent practicability.
Description
The utility model relates to the process equipment of powder material, is the grading plant of micro mist material furtherly.
In existing granular material process equipment, as reducing mechanisms such as ball mill, Raymond mills, can only be crushed to certain fineness (granularity) scope to material, micro mist wherein can not separate, thereby some micro mist has been taken as the material consumption in vain of common granularity.If seek out micro mist (particle diameter below 10 microns), only take other disintegrating apparatus.Thereby waste is very big.
The purpose of this utility model is the grading plant of a kind of micro mist material of design.
The purpose of this utility model realizes according to structure described below.The top of device is a grading room, and the bottom of grading room is one and separates cone and an input and output material cone that vane type grading wheel of one power axial region body transmission is arranged in the grading room, and relative with grading wheel have a micro mist discharge pipe.A feed pipe and a blast pipe are arranged on the input and output material cone.The shell of line shaft parts has a sealing gland chamber, and Compressed Gas inlet is arranged on this chamber, in a side of the close vane type grading wheel of sealing gland chamber a hermetic seal road is arranged.The inlet of Compressed Gas, the sealing gland chamber, the hermetic seal road communicates with one another.
For making this device practical more, also be provided with a sealing gland chamber in the outside of micro mist discharge pipe, also there is a Compressed Gas inlet this sealing gland chamber, in the side near grading wheel an airtight passage is arranged.
The utility model has the advantages that device can be connected on the discharge end on the existing disintegrating apparatus (as Raymond mill).And therefrom isolate required micro mist material.And, be provided with the hermetic seal road at the bearing place, prevent dust seepage in bearing effectively, have fabulous practicality.
Description of drawings, accompanying drawing are structural profile schematic diagrames of the present utility model.Each sequence number in the accompanying drawings is: 1 grading room, and 2 line shaft parts, 3 separate cone, 4 input and output material cones, 5 discharging openings, 6 air inlets, 7 charging apertures, 8 and 13 Compressed Gas inlet, 9 micro mist discharge pipes, 10 grading wheels, 11 and 14 hermetic seal roads, hermetic seal chambers 12 and 15.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
With reference to accompanying drawing, the top of grading plant is grading room 1, grading room is a cylindrical shell, upper end closed, the separation cone 3 of a material of following termination, below the separation cone 3 is an input and output material cone 4, and a feed pipe 7 and a blast pipe 6 are arranged on input and output material cone 4, is the discharging opening 5 than meal bottom.The about centre bit of an end in grading room that line shaft parts 2 line shafts of a power input are housed in the grading room 1 is equipped with the grading wheel 10 of a vane type, this grading wheel rotates under the drive of the axle of line shaft parts, and micro mist enters in the micro mist discharge pipe 9 relative with the line shaft parts through the impeller clearance.The particle diameter of micro mist is minimum, for preventing that micro mist from entering in the bearing of line shaft parts, on the shell of line shaft parts 2, designed a sealing gland chamber 15, Compressed Gas (air or inert gas) is injected by the inlet of the Compressed Gas on the shell 13 in this sealing gland chamber, side in the sealing gland chamber near vane type grading wheel 10 has a hermetic seal road 14, this hermetic seal road one communicates with separation chamber 1 through to the axle sleeve place of bearing.(about 0.05～0.2MPa) enters in the separation chamber Compressed Gas by the hermetic seal road, is negative pressure in the separation chamber, (micro mist discharge pipe 9 connects induced draught system).The micro mist of Shang Shenging can not enter in the bearing under the effect of the barotropic gas at this bearing place like this, has played good axle envelope effect.
In order to make micro mist purer, the utility model also is provided with a hermetic seal road 11 in the junction of grading wheel 10 and micro mist discharge pipe 9, and the structure in this hermetic seal road is similar with the hermetic seal road of line shaft parts.A hermetic seal chamber 12 is arranged in the outside of micro mist discharge pipe 9, and Compressed Gas on it inlet 8 communicates with compressed gas source.11 places, hermetic seal road are malleation, the micro mist that rises can't enter in the discharge pipe from the slit of the grading wheel and the micro mist discharge mouth of pipe under the effect of malleation, can only be to enter between the thin blade of micro mist by grading wheel, thick particle then descends along the shell wall that separates cone 3.The discharging opening 5 of meal below feeding and discharging cone 4 discharged grading plant.
What it may be noted that in addition a bit is, is separating the establishing by top among the feed pipe 16(figure shown in the dotted line of cone 3), the raw material of classification is in this pipe enters into separation cone 3, and micro mist is classified to be entered in the micro mist discharge pipe 9 after taking turns 10 separation.Below feed pipe 7 can seal, also can with top feed pipe 16 charging together (identical material or need the material of abundant mixing-classifying).Feed pipe 7 and 16 can suitably increase, and for example each 2 or 3, need to be used to the food of mixing match, the raw material of medicine etc.
Be particularly suitable for chemical industry, metallurgy, medicine, coating, pigment, the super-fine processing classification of the raw material of industries such as food.
