Abstract
The utility model discloses a nitrogen detection device for preventing a conductive band from deforming. The nitrogen detection device comprises an upper electrode hearth, a lower electrode furnace end, a graphite crucible arranged at the upper end of the lower electrode furnace end, a fixed copper block fixed in the lower electrode furnace end, and a conductive band connected between the fixed copper block and the lower electrode furnace end, wherein the conductive band is arc-shaped with the radian being about 55-700 degrees. By using the nitrogen detection device, the situation that the conductive band loosens and generates plastic deformation gradually caused by largest deformation amount of an outermost-layer or innermost-layer woven belt due to vertical movement along with the lower electrode furnace end can be avoided, the service life is greatly prolonged, the operation efficiency of the unit is greatly improved, and the production cost is lowered.
Description
Technical field
the utility model relates to a kind of pick-up unit, specifically belongs to a kind of nitrogen pick-up unit that can prevent conductive strips distortion.
Background technology
nitrogen pick-up unit by top electrode burner hearth, bottom electrode burner, be arranged on bottom electrode burner upper end graphite crucible, be arranged on fixedly copper billet in bottom electrode burner, be connected in the fixedly conductive strips between copper billet and bottom electrode burner and form.Its bottom electrode burner rises graphite crucible is delivered to top electrode burner hearth contact, make graphite crucible become conductive carrier, utilize electrode two ends by low-voltage, high-current (the most about 5000W of power left and right), at argon gas, being full of under the environment of cavity is warmed up to more than 650 ℃ graphite crucible at short notice, measured object thawing discharges oxygen and nitrogen, then by the content of measuring respectively oxygen and nitrogen of Infrared survey pond and equalized temperature electric bridge.
bottom electrode burner moves up and down in measuring process.The large electric current that conductive strips bear about 1200A in energising heating process passes through.Conductive strips usability is the stability important of the variation of shape to crucible high-temp combustion.Because conductive strips recurvation is 180 degree deflected, the power that ectonexine is subject to is inhomogeneous, be that skin is subject to pulling force, the internal layer power that is squeezed, in the lifting process repeatedly of burner, outermost layer or innermost layer braid over braid produce loose plastic yield gradually because being out of shape maximum, cause resistance to increase gradually, finally because large electric current blows cable by rear generation heat.
utility model content
the purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of conductive strips can be because not moving up and down with bottom electrode burner, makes outermost layer or innermost layer braid over braid produce gradually the nitrogen pick-up unit of loose plastic yield because of distortion.
realize the technical measures of above-mentioned purpose:
a kind of nitrogen pick-up unit that can prevent conductive strips distortion, by top electrode burner hearth, bottom electrode burner, be arranged on bottom electrode burner upper end graphite crucible, be arranged on fixedly copper billet in bottom electrode burner, be connected in the fixedly conductive strips between copper billet and bottom electrode burner and form, it is: conductive strips be shaped as arc, its radian is 55 ~ 70

.
feature of the present utility model is: conductive strips can be because carrying out moving up and down with bottom electrode burner and outermost layer or innermost layer braid over braid produce loose plastic yield gradually because being out of shape maximum, life cycle improves greatly, unit operation rate significantly promotes, and production cost reduces.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is the structural representation of conductive strips in Fig. 1;
in figure: 1-top electrode burner hearth, 2-bottom electrode burner, 3-graphite crucible, 4-is copper billet fixedly, 5-conductive strips.
Embodiment
below in conjunction with accompanying drawing, be described further:
a kind of nitrogen pick-up unit that can prevent conductive strips distortion, by top electrode burner hearth 1, bottom electrode burner 2, be arranged on bottom electrode burner 2 upper ends graphite crucible 3, be arranged on fixedly copper billet 4 in bottom electrode burner 2, be connected in the fixedly conductive strips 5 between copper billet 4 and bottom electrode burner 2 and form, it is processed into arcuate shape by conductive strips 5, and its radian is 55

be in operation, although conductive strips 5 move up and down with bottom electrode burner 2, but each layer of conductive strips 5 is stressed evenly, therefore can not produce metaboly and cause resistance value to increase gradually, finally by rear generation heat, make the impaired phenomenon of conductive strips 5 because of electric current greatly.
