Abstract
The utility model discloses a graphite crucible. The graphite crucible comprises multiple sections of crucible units which are connected in head-to-tail mode. The multiple sections of the crucible units can be produced in an existing manufacturing process such as squeezing and mold pressing and then connected together to from a large-size and high-purity graphite crucible. The multiple sections of the crucible units can be produced in an existing mature process such as the squeezing and the mold pressing and then are connected in head-to-tail mode through threaded connection and bonding technique, and therefore the large-size and high-purity (purity is more than 99.99 percent) graphite crucible is formed. The graphite crucible has the advantages of being simple in manufacturing process and low in cost.
Description
Technical field
The utility model relates to a kind of graphite crucible.
Background technology
Multistage assembling high-strength, antioxidant graphite crucible belongs to the high purity graphite material; Purity is greater than 99.99%; Be widely used in metallurgy, machinery, chemical industry, non-ferrous metal processing and other fields, especially purity had the ideal material of copper industry Aluminum and the melting refining vessel etc. of specific (special) requirements.
Can't produce external diameter greater than 260mm through technologies such as extruding, mold pressings at present, height is greater than the big volume high purity graphite material of 710mm.If static pressure high purity graphites such as employing are made crucible,, cause price very high because of the high purity graphite such as static pressure such as grade of equal volume is big at the difficulty of processing of material yardstick; The shortcoming that purity is on the low side, and its price is ten times of other moulding process high purity graphite price, with causing increasing considerably of use cost; But do not prolong service life, and on the other hand, waiting the static pressure high purity graphite is a monolith; In being processed into the process of crucible, will cause the material of crucible hollow space integral body to draw out, and add and can only be ground into powder man-hour, this powder recycling is worth little; Cause the waste of material; This also is the reason that has increased use cost indirectly, and in sum, to wait the static pressure high purity graphite to carry out melting production be unpractical in use in industry.
Summary of the invention
The purpose of the utility model provides a kind of graphite crucible, and it can overcome the deficiency of prior art, is processed into the high purity graphite crucible of big volume through adopting the splicing of small size high purity graphite unit, and processing is simple, and cost is low.
The purpose of the utility model is achieved in that
A kind of graphite crucible, it includes multistage crucible unit, and the said crucible of multistage unit connects from beginning to end.
Produce multistage crucible unit through existing production technologies such as extruding, mold pressings, the more said crucible of multistage unit is connected, thereby can form big volume high purity graphite crucible.
Among embodiment, the said crucible of multistage unit is through being threaded therein.
Among embodiment, the adhesive bonding is adopted in the junction of the said crucible of multistage unit therein.
Among embodiment, said adhesive is the epoxy resin adhesive therein.
Among embodiment, be in said crucible unit topmost and be provided with guiding gutter therein, the cross section of said guiding gutter is an arc.
Among embodiment, said crucible unit adopts extruding, mould pressing process to process therein.
The utility model compared with prior art has following beneficial effect:
The utility model is produced multistage crucible unit through adopting maturation process such as existing extruding, mold pressing; Again through be threaded and cohere the technology multistage crucible unit is connected from beginning to end; Thereby form the graphite crucible of big volume high-purity (purity is greater than 99.99%), manufacturing process is simple, and cost is low.

Fig. 2 is the left view of the utility model graphite crucible;
Fig. 3 is the vertical view of the utility model graphite crucible.
The specific embodiment
Extremely shown in Figure 3 like Fig. 1, the utility model graphite crucible, it includes multistage crucible unit, and the said crucible of multistage unit connects from beginning to end.In this preferred embodiment, said graphite crucible includes three sections crucible unit 11,12,13, and said crucible unit 11,12,13 connects from bottom to up successively.The recessed formation recess 14,15 of the upper end inner ring of said crucible unit 11 and said crucible unit 12, and be provided with helicitic texture at the vertical plane of said recess 14,15; The lower end inner ring protrusion of said crucible unit 12 and said crucible unit 13 forms boss 16,17; And the vertical plane at said boss 16,17 is provided with screw thread, and then three sections said crucible unit 11,12,13 are connected to form an integral body through said recess 14,15 and said boss 16,17 and threaded engagement provided thereon successively.
For improving the security and the reliability of 11,12,13 junctions, three sections said crucible unit, can be equipped with adhesive at said recess 14,15 and said boss 16,17 places, handle that through high temperature sintering said crucible unit 11,12,13 is bonded together.In this preferred embodiment, said adhesive is an epoxy resin.Smear epoxy resin in the screw thread jointing positions; Make said recess 14,15 and said boss 16,17 fully be stained with sticking; After graphite crucible is put in the Medium frequency induction equipment, 700 ℃～900 ℃ slowly heating make the epoxy resin adhesive eremacausis of seam crossing become simple substance C; Such three sections said crucible unit 11,12,13 will fully be stained with and stick together, and so far this crucible becomes an overall structure.
Like Fig. 2 and shown in Figure 3, be provided with guiding gutter 18 in the upper end of said crucible unit 13, the cross section of said guiding gutter 18 is an arc.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
