Description

The ultra tiny pulverizing internal classification of whirlwind device

The utility model belongs to the ultra tiny pulverizing internal classification of the whirlwind device of in the industries such as being used in metallurgy, building materials, chemical industry and nonmetallic ore non-inflammable and explosive material being pulverized.

Current, domesticly material is carried out in small, broken bits and capital equipment ultra-fine grinding the roller milling machine is arranged.Its major defect is that volume is big, cost is high, energy consumption is high, efficient is low and reaches relatively difficulty of ultra-fine grinding.Shortcomings such as Chinese patent ZL94236603.4 mill without ball is better than the said equipment, but its classification (sorting) mechanism separates with disintegrating mechanism, and is that many groups are multistage, still has volume big, and route is long.

The purpose of this utility model be for the shortcoming of avoiding above-mentioned prior art design a kind of rational in infrastructure, take up an area of few, efficient energy-saving, the ultra tiny pulverizing internal classification of the whirlwind that grinding particle size is adjustable device.

For achieving the above object, the technical solution adopted in the utility model includes the pulverizer of charging aperture and air inlet and is contained in top and its grader with cavity, the gatherer and the blower fan that are communicated with successively with the grader discharging opening.Be characterized in the pulverizing chamber and the outer whirlpool of rotor groove.

The horizontal section of whirlpool groove is a parabolic shape, also can be zigzag or half garden shape.

In pulverizing chamber, the inwall corresponding with the outer garden of rotor is the easiest to be impaired, in order to protect and to be convenient to maintain and replace, is provided with the lining identical with its shape herein, and the whirlpool groove is arranged on the inwall of lining.

Pulverizing chamber is interior to be that the boundary is divided into epicoele A and cavity of resorption B with the rotor.In epicoele A, be located on the rotor and have the vertical tangent plane of the horizontal feed back dish of through hole to be approximate W shape.

For strengthening pulverizing chamber inward turning wind-force degree, the fan blade outer end of radially loading on the rotor disk bottom surface becomes bowing to the rotor direction of advance.Its optimal number is the 12-16 sheet, and best exit installation angle is 110 °-150 °.

On pulverizer and grader, be provided with the ring-type water-cooled mechanism of intake-outlet, to guarantee the normal working temperature of this device.

Pulverizer is contained on the frame, and by following actuating unit, top pulverizing chamber and indoor horizontal rotor and the top thereof that is contained in the vertical pivot upper end are made up of the horizontal feed back dish of last lower through-hole.Rotor is by rotor disk and be contained in the hammering blade of its upper surface respectively and the pulverizing fan blade on the bottom surface constitutes.Blade is at least three of equidistant correspondence, is contained in involute shape between the generating circle and outer garden of rotor disk, and can be strip also, be contained on the tangential direction of rotor disk generating circle.During work, rotor disk will outwards be dished out at a high speed from the material that charging aperture and feed back dish fall, and will be broken and in small, broken bits during it is carried out, i.e. Mechanical Crushing; Gu form gas between hammering blade and the whirlpool groove--high velocity turbulent flow, material is being realized the air-flow pulverizing under the pneumatic flutter effect consumingly; Pulverize fan blade and produce strong cycle of higher pressure air-flow whirlwind and turbulent flow because of running up, make the autogenous grinding of material whirlwind, realize ultra tiny pulverizing.The positive 1-5mm of distance control between hammering blade outer face and the lining regulates this distance, can change by the particle diameter of comminuting matter.Grader is horizontal (also can be vertical), by the cylinder base that is connected with mill housing cover be mounted in it the trunnion axis vertical with ascending air, the impeller that last actuating unit that left end is dynamically connected and right-hand member install, blade are formed.Impeller is the left and right wheels of consubstantiality correspondence, has the through hole that communicates with discharging opening on the wheel of the right side.For guaranteeing effectiveness of classification, between impeller and cylinder base, be provided with containment member.Blade tightens up and is contained on the impeller, is made by high-intensity toughness pottery material, and its optimum angle of incidence is a zero degree.The quantity of blade is according to being required to decide by the processing granularity thickness of comminuting matter.

Gatherer is made of the cyclone collector and the bag collector that are communicated with, and the one side is communicated with grader, and opposite side is communicated with blower fan by control valve.

The blade quantity and the blower fan aperture size of control and adjustment grader rotating speed, grader can be recruited arbitrarily between 2-125 μ m by the processing granularity (particle diameter) of comminuting matter.
