Description
Technical field
The present invention relates to a kind of sintered flux production process.
Background technology
The production technology of sintered flux is in the prior art: prepare burden, add waterglass stirring, granulation, oven dry, screening, sintering, cooling, screening, magnetic separation, packing.Because of the raw material of sintered flux is to add water glass solution by multiple breeze proportioning to make after grain is reproduced in stirring, and water glass solution is sticking, therefore the viscous material through making after the granulation enters and is easy to be bonded in the cylinder dryer on the dryer barrel, and is sticking more thick more, regularly cleaning.The way of cleaning is artificial or machinery knocks barrel, can produce very big noise like this, not only directly influences workman's working environment, and serious to equipment damage, strikes bad back and just must change the stove tube.Knocking the raw material that gets off is big caking entirely, must screen once more after the fragmentation, just can enter dryer, and crushing is very big.In addition, the solder flux after the oven dry enters the high temperature sintering of 800 ℃ of sintering furnace back warps, and the temperature after coming out of the stove is at 500～600 ℃, and so high temperature can not directly be carried out magnetic separation and packing, must be cooled to the normal temperature state.Generally adopt water cooling or air cooling, water cooling needs a cover circulation, and air cooling is big to the production environment influence, and the waste heat of two kinds of way generations all wastes.
Summary of the invention
The technical problem that the present invention solves provides a kind of sintered flux production process, and the one, at the problem of domestic unstable product quality of the same trade, adopted and done, wet to stir and separate the technology of carrying out separately; The 2nd, in the technology that has adopted automatic gauge to add aspect the waterglass interpolation; The 3rd, directly enter into the situation that the cylinder dryer easily is bonded on the dryer barrel and material self easily lumps at viscous material, after granulation, increase the prebake operation, remove the moisture on wet adhesive material surface, make it be difficult for entering into the cylinder dryer again after the bonding and thoroughly dry; The 4th, all reclaim the heat that exchanges out in the air-cooled process, and all deliver to and half-dried solder flux is thoroughly dried in the cylinder dryer, tail gas is discharged to outdoor after cyclone dust removal, make the required whole heat energy of production process intermediate roll dryer all from heat recovery, not only save the energy, and reduced environmental pollution.The 5th, aspect finished product packing, adopt automatic packing technique, improved the automatization level of production line.
Mentality of designing of the present invention:
1, adopts dry powder to stir in the traditional technology and add waterglass and in an equipment, finish, there is the dead angle in stirring, cause the segregation of solder flux composition, quality instability easily, the present invention has adopted and has done, wet stirring separation is carried out separately, eliminated the dead angle, guarantee the uniformity of product composition, effectively improved product quality.
2, in the accuracy of adding that adopted technical guarantee such as pipeline conveying, electronic scale automatic gauge of the present invention aspect the interpolation of waterglass, greatly reduce waste, improved on-the-spot working environment simultaneously.
3, find that by test viscous material can reduce the caking of self under vibrational state, therefore adopt the vibratory liquefaction drying technology that viscous material is carried out prebake, the caking rate of material self is reached below 5%, solve the difficult problem that material self lumps easily in dry run.For material stamping device problem, adopt the method that in equipment, applies anti-stick coating with the material contact portion, solved material stamping device problem effectively, even if there is a spot of bonding also to be easy to cleaning.
4, adopt the heat recovery technology; make heat flux in Air cooler fully and normal temperature air carry out heat exchange; when the heat flux exhausting is cooled to normal temperature; the heat that exchanges out all is sent in the cylinder dryer solder flux through prebake is further dried; its water content is reached below 2%, and tail gas is discharged to outdoor again after cyclone dust removal, and the required whole heat energy of cylinder dryer are all from heat recovery; save the energy, protected environment.
5, adopt the automatic packing technique of finished product, the qualified solder flux of production is weighed according to user's the automatic gauge that requires, guarantee the metering accuracy and the packaging quality of product, improve the automatization level of production line, alleviate working strength of workers.
Technical solution of the present invention:
1. prepare burden: after needed raw material is rechecked, be ground into the powdery of various criterion granularity, proportioning is carried out according to required prescription in the back of sieving;
2. stir: the raw material that proportioning is good is put dried agitator into and is done stirring, puts into wet agitator after stirring again, adds the stirring of wetting of an amount of waterglass;
3. granulation: the raw material after will stirring is sent into comminutor and is carried out granulation;
4. prebake: the granular feedstock that adopts the vibrated fluidized bed dryer that comminutor is produced carries out prebake
5. oven dry: the granular feedstock after the prebake is sent into drying oven, under suitable temperature, dry;
6. screening: the granular semi-finished product that will slough behind the moisture sieve, and sieve out the semi-finished product in the standard particle size scope;
7. sintering: send into sintering furnace and carry out sintering, 800 ℃～900 ℃ of sintering temperatures, sintering time 1～2 hour with sieving out semi-finished product in the standard particle size scope;
8. cooling: the heat flux after coming out of the stove is cooled off;
9. screening, magnetic separation, check, packing.
Described process for cooling adopts the air-cooled switch cooling of negative pressure, and stoving process adopts the cylinder drying machine drying, and the heat that exchanges out of the air-cooled switch of negative pressure is all sent in the cylinder dryer half-dried raw material is thoroughly dried.
