Separation apparatus for tubular throughflow apparatuses

摘要

The apparatus has an annular stack (20) formed of hard and brittle annular discs. The discs are stacked and clamped such that a separation gap (37) for separating off sand and rock particles is formed between each individual discs. Two coupling elements (18, 19) are provided at one or both ends of the stack. A clamping device is provided at one or both ends of the stack. The clamping device clamps the hard and brittle discs flexibly and fastens the stack in a variable fashion on a tubular flow-through apparatus. The brittle material of the annular disc is selected from the group consisting of oxide and non oxide ceramic, mixed ceramic, ceramic material with addition of secondary phase, mixed material with shares of hard ceramic material and metallic binder phase, precipitation-hardened cast iron, powder metallurgical materials with in-situ formed hard material phases or long-fiber and/or short-fiber-reinforced ceramic material.
