Title:
POWDER SUPPLY APPARATUS AND POWDER SUPPLY METHOD
Document Type and Number:
WIPO Patent Application WO/2012/115060
Kind Code:
A1
Abstract:
In this powder supply apparatus, a pressure difference is adjusted to be constant by adjusting pressure in a feed tank (11) by means of an inner pressure adjusting valve (22) connected to the feed tank (11), said pressure difference being a difference between pressure in a carrier gas main tube (33), which is connected to powder transport piping (31), and which introduces a carrier gas for transferring a powder, or pressure in a feed tank (11), and pressure in a powder transport piping (31). A powder flow quantity in the powder transport piping (31) is adjusted to be constant by means of a valve (21) for the powder, said valve being connected to the powder transport piping (31). After the powder flow quantity is adjusted by means of the valve (21), an open degree of the valve (21) is set constant, and the pressure difference, which has been adjusted to be constant at the time of adjusting the valve (21), is adjusted such that the powder flow quantity is constant, by adjusting the pressure in the field tank (11) by means of the inner pressure adjusting valve (22). This invention is capable of accurately controlling, in a short time, the quantity of the powder to be supplied. A powder supply method of the present invention has same features.
