Sintered flux production process

Abstract

The invention relates to a method for producing sinter solder, which comprises preparing material, mixing, making particles, pre-drying, drying, selecting, sintering, cooling, selecting, magnetic selecting, checking, and packing, wherein the invention uses dry-wet mixing separating technique, to eliminate the dead corner and confirm the uniform product, with stable product quality. And it uses vibration fluidize drying technique to reduce block ratio in drying process under 5%. And it coats anti-adhesive coat on the contact with material. The invention uses left heat recycle technique, to recycle the heat when cooling solder into former processes to dry the semi product. And the energy consumed by roller drier is from the left heat.

Description

technical field [0001] The invention relates to a production process of sintered flux. Background technique [0002] The production process of sintered flux in the prior art is: batching, stirring with water glass, granulation, drying, screening, sintering, cooling, screening, magnetic separation, packaging. Because the raw material of sintered flux is made by adding various mineral powders into the water glass solution, stirring and granulating, and the water glass solution is viscous, so the viscous material made after granulation is sent to the drum for drying. The inside of the machine is easy to stick to the wall of the dryer barrel, the more sticky the thicker it must be cleaned regularly. The cleaning method is to manually or mechanically knock the cylinder wall, which will generate a lot of noise, which not only directly affects the working environment of the workers, but also seriously damages the equipment. After the knock is damaged, the furnace cylinder must be ...

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a sintered flux production process. One is to solve the problem of unstable product quality in the same industry in China, which adopts a separate process of dry and wet stirring and separation; The process of metering and adding; the third is to increase the pre-drying process after granulation to remove the surface of the wet sticky material in view of the situation that the viscous material directly enters the drum dryer and is easy to stick to the wall of the dryer and the material itself is easy to agglomerate. The moisture in the air makes it difficult to bond and then enters the tumble dryer for thorough drying; the fourth is to recover all the heat exchanged during the air cooling process and send it to the tumble dryer to completely dry the semi-dry flux , the tail gas is discharged to the outside after cyclone dust removal, so that all the heat energy required by the tumble dryer in the production process comes from waste heat recovery and utilization, which not only saves energy, but also reduces environmental pollution
