In bulk putting of polycrystalline silicon ingot ingot furnace heat unhurried current

The utility model belongs to the technical field of polycrystalline silicon production. An in bulk putting of polycrystalline silicon ingot ingot furnace heat unhurried current, heated board and sideinsulating wall under includes, side insulating wall's inside extension of lower extreme is provided with the butt joint edge, be provided with the scattered subassembly of long brilliant heat unhurried current down between heated board and the side insulating wall, the scattered subassembly of long brilliant heat unhurried current includes outer spacer bush and interior spacer, interior spacer matches the laminating of sliding with outer spacer bush and cup joints, the outer spacer bush upper end is provided with the overlap joint edge of outside extension, works as when side insulating wallis in disjuncture with lower heated board, outer spacer bush passes through the overlap joint and establishes on side insulating wall along match hanging, when side insulating wall when the heated board is at the closure state
