Description

A kind of displacement room being heat-treated kiln

Technical field

The utility model relates to be heat-treated kiln technical field, and in particular to a kind of displacement room for being heat-treated kiln.

Background technique

Displacement room is the key equipment that process gas reaches requirement concentration in the burner hearth for ensure the heat treatment kiln such as roller kilns, Gas displacement is completed in displacement room when material is into and out of burner hearth, to guarantee in furnace in its both ends that heat treatment kiln burner hearth is arranged in Gas concentration is constant.As roller kilns cross-sectional width is more and more wider, the width for replacing room also becomes wider than before, the width of gate Degree is also bigger with area, therefore the sealing at gate needs holding device, just can guarantee the leakproofness after gate increases.

For the leakproofness for improving displacement room gate, it generally can all be arranged in when flashboard is closed and compress holding down assembly for flashboard. However it is existing hold down assembly there are mainly two types of, one is using multiple independent cylinders (generally more than ten) in different location pair Flashboard is compressed, and for this structure there are at high cost, I& M difficulty is big, is difficult to control, the disadvantage of reliability difference, And the service life under environment dusty is difficult to ensure；Another kind is that flashboard is mounted on lifting using complicated movement mechanism In mechanism, make flashboard while can go up and down and translational motion, when realizing that flashboard is closed while can compress, this kind of structure presence Structure is complicated, at high cost, and occupied space is big, the big disadvantage of production, I& M difficulty.

Utility model content
