Utility model content
Technical problem to be solved in the utility model is to provide a kind of graphite batch can producing vanadium nitride, this graphite batch can avoid batch can and push pedal to depart from, and the generation of the even card tank phenomenon of rubbing mutually with kiln chamber or track when preventing batch can from running in kiln, increase the volume of batch can simultaneously, improve vanadium nitride output.
The technical scheme solved the problems of the technologies described above is:
A kind of graphite batch can producing vanadium nitride, its formation comprises graphite tank body and graphite base, graphite tank body is the square tank body that four pieces of vertical panel faces connect and compose, graphite base is the square plate face of horizontal positioned, the bottom of graphite tank body with connect as one structure with graphite base, have venting hole on the top of graphite tank body, have nitriding hole in the bottom of graphite tank body, venting hole and nitriding hole are uniformly distributed in the upper and lower of four sides of graphite tank body.
The graphite batch can of above-mentioned production vanadium nitride, it is circular arc chamfering that crest line place is intersected in adjacent two sides of described graphite tank body.
The graphite batch can of above-mentioned production vanadium nitride, the area in the square plate face of described graphite base is greater than the horizontal section of graphite tank body, the square plate face surrounding of graphite base has a circle cocked bead along graphite tank body outer side, and graphite base has circular arc chamfering in the bight in square plate face.
The graphite batch can of above-mentioned production vanadium nitride, two row's venting holes are arranged respectively at the described top in graphite tank body four sides, have three row's nitriding holes in the bottom of graphite tank body four sides respectively.
The beneficial effects of the utility model are:
1. graphite tank body and base are made of one material tank by the utility model, more stable when batch can is run in kiln, avoid the phenomenon that circular batch can and push pedal depart from, and easy to operate, not fragile in dress discharge process;
2. graphite tank body outer corners and graphite base outer corners are circular arc chamfering, avoid the friction in graphite batch can and kiln, it also avoid the friction of graphite material pot bottom and kiln chamber inner orbit;
3. the venting hole on graphite tank body top and the nitriding hole of bottom contribute to gas in reduzate and to discharge and in nitriding process, nitrogen enters and participates in reacting, and improve speed of reaction;
4. graphite tank interior is square structure, compared with the circular graphitic batch can of same diameter, improves single tank output;
5. the cocked bead of graphite base makes to keep certain gap between graphite tank body, increases the circulation of gas, contributes to material and fully react.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
In figure, each label is: chamfering 6, graphite base cocked bead 7, graphite tank interior 8 outside chamfering 5, graphite base outside graphite tank body 1, graphite base 2, venting hole 3, nitriding hole 4, graphite tank body.
Embodiment
The utility model comprises graphite tank body 1, graphite base 2.
Show in figure, graphite tank body 1 is square tank body, and square tank body is connected and composed by four pieces of vertical panel faces, and graphite tank interior 8 is square, and square structure batch can, compared with the circular batch can of same diameter, can improve single tank output.
Show in figure, graphite base 2 is the square plate face of horizontal positioned, the bottom of graphite tank body 1 with connect as one structure with graphite base 2, it is more stable when integrative-structure makes graphite batch can run in kiln, avoid the phenomenon that circular batch can and push pedal depart from, and it is easy to operate, not fragile in dress discharge process.
Show in figure, the area in the square plate face of graphite base 2 is greater than the horizontal section of graphite tank body 1, the square plate face surrounding of graphite base 2 has a circle cocked bead along graphite tank body 1 outer side, graphite base cocked bead 7 makes to keep certain gap between graphite tank body 1, increase the circulation of gas, contribute to material and fully react.
Show in figure, have venting hole 3 on the top of graphite tank body 1, have nitriding hole 4 in the bottom of graphite tank body 1, venting hole 3 and nitriding hole 4 are uniformly distributed in the upper and lower of four sides of graphite tank body 1.The venting hole 3 on graphite tank body 1 top and the nitriding hole 4 of the bottom gas contributed in reduzate is discharged and in nitriding process, nitrogen enters and participates in reaction, improves speed of reaction.
