APPARATUS FOR SAMPLING SUSPENDED SOLID SUBSTANCE

摘要

PURPOSE:To automatically obtain a predetermined amount of a suspended solid substance mixed liquid as a sample liquid, by arranging a sample line to the flowline of the suspended solid substance mixed liquid to be sampled as a bypass line to permit said mixed liquid to flow through the sample line. CONSTITUTION:A sample line (b) is arranged to the flowlines a1, a2, a3 of a suspended solid substance mixed liquid to be sampled as a bypass line and a filter holder 1 is interposed in the line (b) in a detachable manner through a quick joint 2 while a differential pressure meter 3 is together provided before and after the filter holder 1. In addition, a flow control valve V1 is provided to the forward part of the holder 1 and an integration flow meter 6 is provided to the rear part of the bypass line. Further, a pressure detector 4 for monitoring inlet pressure is provided to the inlet side of the sample line (b) and a pure water supply line (c) having an opening and closing valve V10 and a check valve V11 mounted thereto is provided in connected relationship.
