Embodiment Construction

[0010] A method for drying electrolytic silver powder, adopting steam as a heating medium for drying the silver powder, and using a disc continuous dryer as the drying equipment for the electrolytic silver powder.

[0011] Such as figure 1 As shown, the steam with a pressure of 0.5MPa is introduced from the inlet 3, and enters the hollow drying plate through the pipe. Steam enters from one end of the drying plate and exits from the other end. The wet silver powder is added to the first layer of drying plate on the upper part of the plate dryer 2 by the quantitative feeder 1, and the rake arm with rake blades makes a rotary motion to continuously turn over the silver powder. The silver powder on the small drying plate is moved to the outer edge of the drying plate, and falls to the outer edge of the large drying plate below. On the large drying plate, the silver powder moves inward and falls into the next layer of small drying plates from the middle discharge port. Both large...

Abstract

The invention discloses a drying method for electrolytic silver powder, relating to a drying method for metal powder materials. The drying method for electrolytic silver powder is characterized in that steam is used as a heating medium for drying the silver powder, and a disc type continuous dryer is used as drying equipment of silver powder. The drying method for electrolytic silver powder has the advantages of high automation control level and simple operation. After the feeding of material is stopped, the internal of the equipment can be cleaned and observed through a viewing door and a sight glass; a large amount of acid mist produced in the work process is absorbed by a vacuum pump, and the working environment of the work field is effectively modified.

Description

technical field [0001] A drying method for electrolytic silver powder relates to a drying method for metal powder materials. Background technique [0002] In the precious metal smelting process, the electrolytic silver powder produced by silver electrolysis needs to be washed and dried before storage. At present, in the precious metal smelting industry at home and abroad, the drying process of silver powder is adopted in the kang room drying process, that is, the electric furnace wire is arranged in the brick room, the wet silver powder is placed on the plate and lifted to the drying rack, and then the full kang plate Push the drying rack into the kang room, and dry it after turning on the power. The labor intensity during the operation is very high. Because the work of the electric kang room is static, the silver powder cannot effectively absorb heat, so that most of the heat is discharged directly, resulting in energy waste. Due to the poor sealing of the kang room, par...
