Description
Technical field
The utility model relates to the pug of a kind of refractory and carbon product and makes field, relates in particular to a kind of resin-bonded goods prilling field.
Background technology
The prilling of prior art generally comprises granulation and dry two steps:
The object of granulation: solve mixing of low specific gravity material (as graphite) and high specific gravity aggregate (as fused alumina, magnesia, zirconia, silica etc.), eliminate all raw materials of orientation row homogenizing of graphite, make the pug with superperformance.
If 1. orientation is parallel direction compression, due to the contraction of graphite layers, make deformation of creep ability become large, thermal stress diminishes, dilatancy large (can cause goods rupture strength to reduce nearly half);
2. if while being orientation perpendicular to compression direction, creep is little, thermal stress is large, and dilatancy is little.
3. parallel direction is higher by 10～20% than vertical direction thermal conductivity.
Dry object: by dry solvent unnecessary in pug, the intensity of increase particle, the minimizing moulding crackle removed.
Pug or powder for qualified moulding, have certain particular/special requirement:
1. laxity, to guarantee pug filling mould equably
2. high as far as possible bulk density
3. moisture or volatilised liq lack 0.5～3% as far as possible, and excessively wet material easily causes crackle
4. conventionally adopt fine powder material, can be also containing coarse grained, but at this moment must have enough fine powders, and allow fine powder wrap up fully coarse granule.
5. in the time of moulding aluminium carbon goods, generally adopt many fine powders, the less pug of coarse granule size is as the largest particles <2～1mm.
6. while adopting liquid resin bonding agent, after pug mixes, generally will allow the sweetening agent in resin volatilize fully, low-temperature bake even sometimes, allows it fully volatilize, and obtains being easy to the pug of moulding.So often need 30～60 minutes dry in dry bucket.
And the prilling of prior art generally all adopts normal temperature granulation, prilling temperature need to be 25 ± 5 DEG C of viscosity with guarantee resin, plasticity, humidity need to be controlled at 45 ~ 60% and ensure that the stability of pug volatile matter is plasticity, so need to add a large amount of resins and solvent to reduce the viscosity of resin, solve the wetting problem of material, conventionally drop temperature is at 45 ~ 60 DEG C, when discharging, contain a large amount of solvents approximately 3 ~ 5%, solvent evaporates causes heat to run off in a large number, need to supplement a large amount of heats and be dried unnecessary solvent, the method of prior art is generally after granulation completes, add follow-up drying dry discharging, pug is in drying, roll, disperse, effectively particle reduces, fine powder increases (reaching 10%), when moulding, dust is more, environment is poor, material is after drying completes, pass through again compressing, product strength fluctuation is large, poor stability, address this problem and conventionally take to add amount of resin, increasing solvent solves again, bring the material result processed of vicious circle.Due to increasing of amount of resin quantity of solvent, extend drying time, and pug rolls in drying, jitter time dry, and effectively particle reduces, and fine powder increases, and cost increases greatly.
Prior art is for solving the problems of the technologies described above, also have bonding agent used, aggregate, additive, powder etc. be heated to uniform temperature in advance, but due to early stage prilling temperature can not be too high, after granulation completes, also must be dried, therefore operation inconvenience, the large and DeGrain of energy waste.
Summary of the invention
The utility model is for the deficiencies in the prior art; provide a kind of granulating and drying synchronously to carry out; be not subject to external environment condition (temperature humidity) impact; without entering in addition, drying is dried; simple in structure; pug steady quality, production efficiency is high, cost-saving resin-bonded goods high temperature comminutor and high temperature prilling process thereof.
For reaching the utility model object; provide following technical scheme: a kind of resin-bonded goods high temperature comminutor; comprise frame, be arranged at the transmission device that the Sloped rotating cylindrical shell in frame, the transmission device of controlling the stirring rotator High Rotation Speed in rotary barrel body and control cylindrical shell rotate; it is characterized in that described rotary barrel cylindrical shell is inside and outside double-layer barrel; in urceolus, be provided with heater and be marked with heatable liquid, described Sloped rotating cylindrical shell angle of inclination is and 5 ~ 35 ° of the angles of vertical direction.
Tilt 5 ~ 35 ° to horizontal direction by revolving rotary barrel body, make its creep, thermal stress, dilatancy reaches a suitable point, puies forward high thermal conductivity.And by double-layer barrel is set, to inner barrel heat conduction, progressively improve temperature of charge by outer cylinder body.
Control the belt drive system that the transmission device of the stirring rotator High Rotation Speed in rotary barrel body comprises stirring motor, is connected with stirring motor, described belt drive system and stirring rotator be in transmission connection (also can pass through shaft coupling direct-drive).
The transmission device of controlling cylindrical shell rotation comprises the rotary electric machine that is arranged at the gear train assembly of cylindrical shell bottom and is connected with gear train assembly.
For reaching the utility model object; improve following resin-bonded goods high temperature comminutor high temperature prilling process; it is characterized in that comprising the following steps: will revolve rotary barrel body and be heated to 40 ~ 120 DEG C; granulating raw material is added to mix and blend in rotary barrel; drum speed 5 ~ 30rpm, high speed rotor mixing speed is 1000 ~ 2000rpm, mixing time is 10 ~ 60 minutes; last discharging, is cooled to room temperature and makes finished product pug.
Key problem in technology of the present utility model is to utilize the gradual of interior conduction, while making granulation in earlier stage, the temperature of material ensures to be unlikely to too high at certain value, later stage is along with inner core temperature raises gradually, realize being dried material, effectively prevent external environment condition (temperature humidity) impact, improve the stability of pug.
