A kind of modified laboratory two-stage ultramicro grinding unit
The utility model relates to a kind of modified laboratory two-stage ultramicro grinding unit, belongs to superfine communication technique field.
So micronizer has adopted the principle of wind filter because smashing fineness is high, whole system, by feed hopper, is pulverized cabin, cyclone separator, negative-pressure air fan, the compositions such as deduster.At present, laboratory micronizer kind is a lot, according to pulverization principle, can be divided into air-flow crushing formula, ball milling formula, shearing and weight abrading type etc., more than smashing fineness all can reach 300 orders, even reaches and receives the fineness of micron (diameter is less than 1 micron).But these micronizers are all that segmentation is pulverized mostly at present, and raw material must first carry out elementary pulverizing with other disintegrating apparatus before entering micronizer, make fineness of materials arrival 50-80 orders put into again micronizer afterwards and carry out secondary micronization processes.This ultramicro grinding mode can not reach the continuous operations of materiel machining, not only working (machining) efficiency is low, and waste time and energy, simultaneously, restriction due to micronizer process principle, a lot of thermal sensitivity, the material that pliability is strong can not, by maximum refinement, make all kinds of micronizers have very large restriction to the raw material of processing.
Utility model content
The utility model is the deficiency for existing laboratory micronizer, utilize the filter screen and the cooling water recirculation system that in unit, arrange, realize raw material property ultramicro grinding once on one group of equipment unit, can continuous operations, and unit processes in low temperature environment, and be applicable to the micronization processes of various thermal sensitivity, pliability raw material.
To achieve these goals, the technical scheme that the utility model adopts is:
A modified laboratory two-stage ultramicro grinding unit, comprises shearing high speed disintegrator, feeding screw, micronizer and cyclone separator; Described shearing high speed disintegrator is arranged at feeding screw top, and described feeding screw material outlet is connected with micronizer, and described micronizer discharging opening is connected with cyclone separator.
Described shearing high speed disintegrator is comprised of warehouse and Cang Gai, the side of covering, described storehouse arranges shear motor, charge door and dust outlet, described dust outlet arranges dust collection cloth bag, described Cang Gai can open by unscrewing storehouse lid set bolt, described high speed disintegrator cabin lid bottom arranges shear-blade, described shear-blade is connected by blade fixing device with shear motor, described shear-blade can be unpicked and washed, change, described shearing high speed disintegrator inside arranges filter screen, described filter screen is fixed on warehouse by filter screen fixed screw, described filter screen can be dismantled by unscrewing filter screen fixed screw at any time, change, clean, described shearing high speed disintegrator warehouse below is bullet, described bullet lower end arranges material outlet.
Described filter screen arranges sieve aperture, and described sieve diameter can be 0.425mm-0.150mm.
Described feeding screw outer setting cooling water recirculation system, right-hand member arranges material inlet, and left end arranges material outlet.
Described micronizer casing surrounding arranges condensed water interlayer.
The utility model is simple in structure, easy to operate, highly effective and safe, utilize filter screen in shearing high speed disintegrator by after the material filtering of one-level precomminution, directly by the feeding screw with condensed water circulation device, be transported to and in micronizer, carry out secondary ultramicro grinding, finally by cyclone separator selection by winnowing, go out final wanted fineness material particulate, realized the serialization processing operation of material superfine comminution, time saving and energy saving, greatly improved working (machining) efficiency.Meanwhile, on feeding screw and micronizer, be also provided with condensed water circulation device, realized material and from start to finish all in low temperature environment, processed, make a lot of thermal sensitivity degree are high, pliability the is strong material can be by maximum micronization processes.
