Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model is further described with the specific embodiment in conjunction with the accompanying drawings in bottom:
As shown in Figure 1, a kind of LMZF efficient rotor combined type desulfurization powder process powder concentrator, from bottom to top by the slower conical tube body, the secondary separation chamber, conical shell, separating chamber 5, air-out cylindrical shell 4 is formed housing unit, described slower conical tube body bottom is provided with the meal outlet, described secondary is provided with second-stage separator 8 in the separation chamber, be horn-like cylindrical shell and tangential vane structure in shape, the outside of secondary separation chamber is respectively equipped with air inlet 9 and secondary air mouth 10, described separating chamber 5 inner chambers are equipped with the cage rotor 6 and the material-strewing device 7 of the inferior pyramidal of one each other, rotor 6 is installed in the lower end of main shaft, the other end of main shaft links to each other with the variable-frequency motor 1 that is installed in housing unit top by transmission device, charging aperture places the centre position on housing unit top, the passage of charging aperture places air-out cylindrical shell 4 and selects inner chamber between the powder cylindrical shell 5, air-out cylindrical shell 4 be evenly distributed on 4 of the housing unit outside or 6 cyclone separators 2 and communicate, the top of cyclone separator 2 is provided with discharge pipe 3 and air outlet, and the bottom is provided with the fine powder outlet.
The course of work is as follows:
Air-flow is under the draw of blower fan, air communication in the ball mill is crossed the secondary air mouth 10 of powder concentrator and introduced powder concentrator, converge in the bottom of powder concentrator with a wind (natural wind), under the guide vane effect of second separator 8, the rotation field of force of form rising is carried leftover materials and is entered into and select powder cylindrical shell 5 after the material secondary sorting that the draft of ball mill is carried.
Mixed material is through " charging aperture " feeding, fall with cage rotor 6 all-in-one-piece spreading disks 7 on, cage rotor 6 and spreading disk 7 next superhigh speed running of drive at transmission device, material on the spreading disk 7 radially throws away under action of centrifugal force and is scattered in and selects in the powder cylindrical shell 5, meet with the rotation ascending air, in separating chamber 5, the air-flow of cage rotor 6 near surfaces and the material that is scattered in the air-flow are done rotation at a high speed synchronously with the classification circle under the drive of classification circle, thereby further strengthened the intensity of centrifugal force field that should the zone, material is realized thick in this zone, the classification of fine powder.
Fine powder after the classification (qualified finished product) carries down at air-flow and enters the cyclone separator 2 that communicates with air-out cylindrical shell 4 by cage rotor 6, in the cyclone separator 2 of efficient low-resistance, finish gas, the solid separation, fine powder is drawn off by product outlet, air-flow gathers and enters discharge pipe 3, and the air-flow after gathering is carrying the part fine powder and entering emptying behind the bag filter.
Under centrifugal action, the meal after the classification is adherent sedimentation in separating chamber 5, when falling to second separator 8, and secondary sorting in second separator 8.Gaseous suspension separation Theory according to solid particle, guarantee in the structural design that there is the higher air-flow rate of climb in this zone, and the fine powder overwhelming majority that will sneak in the meal that separating chamber 5 falls sorts out once more, carry in the separating chamber 5 and separate once more, thereby fine powder content in the meal is reduced to bottom line, meal after the secondary sorting is drawn off by " meal outlet ", is delivered in the ball mill to grind again.
