Title:
SMALL AMOUNT TAKEOFF DEVICE FOR FINE POWDER-VISCOUS FLUID OR THE LIKE
Document Type and Number:
Japanese Patent JPS63283739
Kind Code:
A
Abstract:

PURPOSE: To discharge the micro-amount smoothly and continuously by providing an upper end opening of a powder removal tube connected with the bottom section of a hopper as a micro-diameter, making the diameter of opening the tube small at the upper end and larger than it at the lower end and subjecting it to communicate through from the upper end to the lower end.

CONSTITUTION: Before discharge of fine powder for carrying out the surface treatment such as thin coating, etc., fine powder is flowed from the upper end small opening 4 of the removal tube 3 opened in a hopper 2 little by little down into the removal tube 3 through the inside of the tube by vibration given from a vibration plate 1 and discharged out of the lower end opening. At that time, the fine powder flowed from the small opening 4 into the tube without generating a bridge at the upper section of the upper end opening 4 of the tube 3 is diffused immediately inside an empty hole 5a expanded in the lower section. The fine powder, therefore, is flowed downward smoothly without generating any bridges around the small opening 4 or any contact resistance caused by flocculation to disturb the smooth flowing.
