Description
Technical field
The utility model relates to graphite tube material preparation field more particularly to a kind of split type graphite tubes.
Background technique
Because graphite elevated temperature strength is good and materials are easy and doting on by producer.Graphite has good conduction, leads
Hot property, and there is more skies and small thermal expansion coefficient, therefore graphite becomes one of the material of most resistance to thermal shock, the resistance of graphite
Temperature coefficient is small, and thermal inertia is low, quickly can heat and cool down, and does not have particular/special requirement in workpiece treatment process, is relatively suitble to
The application of vacuum drying oven heater, graphite are relatively good vacuum drying oven heaters, have high temperature resistant, indeformable, impact resistance, radiation
The advantages of area is big, flexible, easy to process and installation.
Existing graphite tube needs to purchase a large amount of blank material since specification is larger, leads to higher cost, notched
Graphite tube production get up it is relatively time-consuming, be difficult to be widely popularized in the market.
Utility model content
According to technical problem set forth above, and provide a kind of split type graphite tube that concave and convex platform mode connects.This is practical
The technological means of novel use is as follows:
A kind of split type graphite tube, by the graphite tube I as bottom, several graphite tubes II as centre connection and conduct
The graphite tube III at top is spliced,
I bottom of graphite tube is smooth flat, and top is equipped with a circle lug boss I,
II bottom of graphite tube is the concave part I for being adapted to the lug boss I, and top is and the I specification phase of lug boss
Same lug boss II,
III bottom of graphite tube is concave part II identical with I specification of concave part, and top is smooth flat, each convex
The portion of rising and concave part are opened in plane where graphite tube inner ring, the width of the graphite tube inner ring and the width of graphite tube outer ring
It is equal,
When the cross section of the body part of the graphite tube I, graphite tube II and graphite tube III is circular arc, each circular arc is excellent
Arc；When the cross section of the body part of the graphite tube I, graphite tube II and graphite tube III is regular polygon jaggy, Qi Gebian
The sum of length is more than the 1/2 of complete regular polygon perimeter.
Preferably, II quantity of graphite tube is n, n=2.
Preferably, straight line and notch where two outer ring endpoints of circular arc/regular polygon to the center of circle/regular polygon center
Straight line angle where midpoint and the center of circle/regular polygon center is α, α=45 °.
Preferably, each graphite tube inner ring endpoint carries out chamfered, as sealing track groove.
Lead to preferably, the intersection of each graphite tube inner ring and the endpoint of outer ring opens up sealing striped in short transverse
Hole.
Preferably, the sealing striped number of openings is 2, the distance and through-hole II of through-hole I to bottom end arrive through-hole I
It is equidistant.
Big graphite tube is split into the small graphite tube that multistage is easily worked by the utility model, passes through the mutual spelling of small graphite tube
Cooperation is connect, the cost of material is reduced, reduces the degree-of-difficulty factor of processing, the utility model can be in graphite mo(u)ld based on the above reasons
Tool preparation field is widely popularized.
