Background technology

Graphite has heat conduction, conduction, high temperature resistant, corrosion-resistant and characteristics that plasticity is good, and different industries is strict to graphite particle size, and in industrial production, the intermediate products of production are more, can not satisfy industry requirement.Because graphite smoother, the little light weight of proportion, the sieving machine that present classification is aborning adopted often, grading effect is poor, the interior of cyclone separator all is to adopt fixing inner core, then cyclone separator can only be suitable for the graphite production with a kind of specification, what also have is to solve a classification difficult problem, force subhead with small round screen, air-flow sieve, but the output of producing is little, equipment is fragile, keep in repair more frequent, seriously polluted, and in device fabrication, can't seek survival as required and produce the graphite of different size, yield poorly, of poor benefits.

The utility model content

The purpose of this utility model is be to solve the problem that grading of poor quality, production efficiency low of graphite in producing, and a kind of efficient height, quality are good, the equipment that is used for the graphite particle size classification of environmental protection thereby provide.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of equipment that is used for the graphite particle size classification, mainly form by pulverizer, grader, first cyclone separator, second cyclone separator, blower fan and dedusting blanking device, blower fan is arranged between second cyclone separator and the dedusting blanking device, described grader is provided with vibratory sieve, be provided with rotary screen in it, cyclone separator is provided with flexible inner core and regulation and control window.

The utility model, described flexible inner core is made up of inner core and core retainer plate.

The beneficial effects of the utility model are: it is more energy-conservation to adopt wind-force to carry, and by regulating air quantity, wind speed and grading wheel rotating speed, makes the rotary screen aperture be variable coefficient, and grading effect is better; Be provided with scalable inner core in the cyclone separator, can regulate the material sinking speed, cooperate wind hole instrumentality material granularity settling amount, can regulate and control the material thickness on demand, controllability is strong in the classification of material; The performance of grader and cyclone separator improves, and makes that the grading effect of whole production flow process is good, and classification efficiency also is improved, and then production efficiency is also just improved; Equipment cost is low, energy-conservation also environmental protection.
