PROBLEM TO BE SOLVED: To easily perform the taking-out and cleaning work of a magnetic small pipe, in an apparatus making pieces of magnetic bodies in powdery or granular matters adhere to the magnetic small pipe to remove the same, by attaching a lid to one end of an outside container to make the container freely openable and closable at one end side thereof and boring a hole for allowing the powdery or granular matters pass through in a peripheral wall of the outside container. SOLUTION: A support cylinder 1 into which a magnetic small pipe 6 is inserted is housed in an outer cylinder 17 made freely openable and closable by attaching a lid 24 to one end side (lower end) of the cylinder 17 and a plurality of pairs of through-holes opposite to each other are formed in the peripheral wall of the support cylinder 1, each pair having concentric axis passing the center axis of the support cylinder 1. Powdery or granular matters introduced from piping 50 pass through the passage formed by the outer cylinder 17 having the support cylinder 1 included therein, a passing hole 28 and a side pipe 29 to be sent out in the direction shown by an arrow (H) but, at this time, pieces of magnetic bodies contained in the powdery or granular matters adhere to the magnetic small pipe 6 to be removed. When this apparatus is cleaned in a connected state, the lid 24 of the outer cylinder 17 is detached to pull out the support cylinder 1 and the magnetic small pipe 6 inserted in the support cylinder is drawn out to be cleaned. |
