Description
Technical field
The present invention relates to a kind of Equipment for Heating Processing more particularly to a kind of net belt type Equipments for Heating Processing.
Background technology
Existing meshbeltfurnace or net belt type Equipment for Heating Processing include feed zone, quenching section and cleaning section, and each section is sequentially connected
So as to which workpiece continuous conveying be handled.When workpiece carries out quenching treatment, due to workpiece temperature height, it is situated between so entering quenching
A large amount of oil smoke live steam can be generated during matter, oil smoke (steam), which floats, to be entered in burner hearth, and the protective atmosphere in burner hearth can be generated
It influences, influences workpiece quality and workpiece color.So it is just highly desirable in ullage setting oil curtain curtain during quenching.
Though traditional oil curtain funnel structure can generate oil curtain, also there is the drawbacks of being inconvenient to adjust.There are two drawback is main, one
It is that the oil smoke generated between oil curtain and liquid level does not discharge approach effectively or can escape from oil curtain curtain, floats and enter burner hearth；Second is that
Since spray seam is narrow, when the unclean impurity of hardening media is more, spray seam is easy to block, and curtain is can not form in injection, but
Splashes even understand direct spirt burner hearth, generate a large amount of smog sometimes.It is always the difficulty for quenching quality control that spray seam, which blocks,
Topic, first, be not easy to find, besides spray seam is inconvenient to clear up, and when Inspection and maintenance is required for blowing out to cool down, and evacuate quenching tank
Interior hardening media.It is time-consuming and laborious.
In addition, feed zone, in charging, since conveyer belt is without some limiting devices, in transport, positions of materials occurs empty
Run, so not only can due to lack material cannot and alarm, remain in operation, increase production cost, and can cause production production
Quality cannot be met the requirements.
Invention content
