Title:
OSCILLATION PIPE WASHING DEVICE FOR OSCILLATION VALVE TYPE HIGH VISCOUS FLUID PUMP
Document Type and Number:
Japanese Patent JP3404587
Kind Code:
B2
Abstract:
PURPOSE: To simplify operation to position a washing pipe to the front end of an oscillating pipe during washing of the oscillation pipe and connection therebetween.
CONSTITUTION: An opening 15 is formed in a position deviated from the two suction delivery ports of the front side wall 1a of a hopper 1 and in the oscillation radius position of the front end of an oscillation pipe 6. The size of the opening 15 is increased to a value higher than that of the oscillation pipe 6 by a given amount to allow the passage of a washing pipe 18. A washing pipe guide mechanism 24 is arranged on the outer surface side of the front side wall 1a of the hopper 1. During washing of the oscillation pipe 6, by rotating the oscillation pipe 6, a front end is positioned facing the opening 15, and the washing pipe 18 is moved by a washing pipe guide mechanism 24 of the outside of the hopper and connected to the oscillation pipe 6. Movement of the washing pipe 6 is performed along a two-dimensional locus deviated from an operation lever 9.
