Abstract

The utility model discloses a square graphite crucible which is formed by a square graphite crucible wallboard, a square graphite crucible bottom board and a square graphite crucible cover. The section view face belt of the bottom of the square graphite crucible wallboard is in an L shape and is connected with the square graphite crucible bottom board. The edge of the square graphite crucible bottom board is processed into a T shape and fixed at the L-shaped bottom of the square graphite crucible wallboard. The edge of the square graphite crucible cover is in a T shape and fixed at the top of the square graphite crucible wallboard. The square graphite crucible is simple in structure, reliable in performance, high in effective utilizing rate in a high-temperature hot field, low in cost and suitable for massive production.

Description

Square plumbago crucible

Technical field

The utility model relates to graphite purification technique field, more specifically relates to a kind of square plumbago crucible, makes it in the thermal field of high temperature ventilation purifying Graphite Powder 99 more than 2400 ℃, can realize that highly effective and safe uses reliably.

Background technology

China's man-made diamond industry still is in the fast-developing phase, and output occupies the whole world the one, in powder assembling diamond synthesis, needs a large amount of ultra-high purity Graphite Powder 99s to make carbon source; Require its foreign matter content therefore less than 25ppm.; Must the Graphite Powder 99 plumbago crucible of packing into be placed on the high temperature that is heated in the graphitizing furnace more than 2400 ℃, and feed nitrogen; Chlorine; Gases such as dichloro fluorine dodecyl carry out purifying. and traditional plumbago crucible all is to select for use circular Ф 600～Ф 800 Graphite Electrodess to process. and its advantage is to select materials and process all easylier, on vertical lathe, is easy to implement processing. but to compare with square plumbago crucible, its effective rate of utilization in the high temperature thermal field is lower; The 78.5%. that is merely square plumbago crucible that is to say; Under the situation of equal shove charge sectional area and identical power consumption consumption gas, pack into the output of purifying Graphite Powder 99 of square plumbago crucible is 1.274 times of circular plumbago crucible. therefore; Select for use circular plumbago crucible to come the cost of purifying Graphite Powder 99 higher, this highly energy-consuming purifying Graphite Powder 99 technology is also mutually vigorous with the energy-saving and emission-reduction policy of country.

But; The difficulty of selecting materials and processing of square plumbago crucible is very big; On vertical lathe (milling machine), all being difficult to implement. the utility model has adopted innovative ideas and novel material, makes square plumbago crucible be able to come out, and successfully is applied on the thermal field of man-made diamond purifying Graphite Powder 99.

Summary of the invention

In order to overcome the existing deficiency of circular plumbago crucible in purifying Graphite Powder 99 Technology, the purpose of the utility model is to be to provide a kind of square plumbago crucible, and this crucible is simple in structure; Dependable performance; Effective rate of utilization in the high temperature thermal field is higher, and is with low cost, is applicable to batch making.

For solving the technical barrier of selecting materials and processing of square plumbago crucible, the utility model solves the technical scheme that its technical problem adopted and is:

A kind of square plumbago crucible, by square graphite sidewall of crucible plate, square plumbago crucible base plate and square graphite crucible cover constitute.The bottom of square graphite sidewall of crucible plate analyse and observe wear L-shaped; L shaped band links to each other with square plumbago crucible base plate; So that hold the square plumbago crucible base plate of band T shape, the edge of square plumbago crucible base plate also is processed into T-shaped, so that make the edge T shape of square plumbago crucible base plate be fixed on the L shaped bottom of square graphite sidewall of crucible plate; The edge of square graphite crucible cover also is processed into T-shaped, so that make the edge T shape of square graphite crucible cover be fixed on the top of square graphite sidewall of crucible plate.The bottom sectional plane of square graphite sidewall of crucible plate has one with L shaped step.

The beneficial effect of the utility model is that the material of selecting materials of square plumbago crucible is the same with circular plumbago crucible, thereby can guarantee its safe and reliable use in the thermal field of high temperature ventilation purifying Graphite Powder 99 more than 2400 ℃.And the advantage of square plumbago crucible has been to give full play to the utilization ratio of its finite space in high temperature thermal field more than 2400 ℃; In equal shove charge sectional area and identical power consumption; Water consumption; Under the situation of consumption gas, pack into the output of purifying Graphite Powder 99 of square plumbago crucible is 1.274 times of circular plumbago crucible.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

Can know that according to Fig. 1 a kind of square plumbago crucible is by square graphite crucible cover 1, square graphite sidewall of crucible plate 2,3 constitute at the bottom of the square plumbago crucible.It is characterized in that: the bottom of square graphite sidewall of crucible plate 2 analyse and observe wear L-shaped; The L shaped band in bottom of square graphite sidewall of crucible plate 2 links to each other with square plumbago crucible base plate 3; So that hold the square plumbago crucible base plate 3 of band T shape; The edge of square plumbago crucible base plate 3 also is processed into T-shaped, so that make the edge T shape of square plumbago crucible base plate 3 be fixed on the L shaped bottom of square graphite sidewall of crucible plate 2, the edge of square graphite crucible cover 1 also is processed into T-shaped; So that make the edge T shape of square graphite crucible cover 1 be fixed on the top of square graphite sidewall of crucible plate 2, the bottom sectional plane of square graphite sidewall of crucible plate 2 has one with L shaped step.

The machining path of the square graphite sidewall of crucible plate of this device is, chooses the quadrel electrode ink material of 600X600X1800 or 800X800X1800, cuts into two sections and planar end surfaces; Diamond head with lengthening is housed is got four bullports; To be coated with adamantine Ф 5 steel wire penetrating, carry out the line cutting, when treating to pass the band saw skin; Carry out sawing its core taken out, and its underpart is processed into L shaped square graphite sidewall of crucible sleeve-board.

The working condition that this device uses in the thermal field of high temperature ventilation purifying Graphite Powder 99 more than 2400 ℃ is garden shape plumbago crucible shove charge, square plumbago crucible shove charge.
