PIPE UNIT FOR RAW MATERIAL LOADING APPARATUS, AND PIPE USED FOR THE PIPE UNIT

摘要

PROBLEM TO BE SOLVED: To provide a pipe unit for a raw material loading apparatus, the raw material loading apparatus: including a raw material passage with an exit end enabled to easily move in a state that raw material may be loaded from a raw material accommodation section; thereby being good in operability.

SOLUTION: The raw material loading apparatus includes: the raw material accommodation section accommodating the raw material; the raw material passage 12 through which the raw material is fed in an airtight state and loaded into a processing apparatus from its exit end 12a; a feeding mechanism that feeds in an airtight state the raw material from the accommodation section to the raw material passage 12; a closing section 14 that can close the raw material passage 12 between a processing apparatus side and a raw material accommodation section side; and a joint section 15 that separates and joins the raw material path at a portion on a raw material accommodation section side than the closing section 14, of the raw material passage 12. The pipe unit is used for the raw material loading apparatus, and constitutes a part of the raw material passage 12. The pipe unit has a pipe inlet end serving as an inlet of the raw material and a pipe exit end corresponding the exit end of the raw material passage, and is telescopic with a position of the pipe inlet end fixed.
