fig. 2 is a cross-sectional view taken along line KK of fig. 1.
Wherein: 1. a crucible base; 2. a split body; 3. a first body segment; 4. a second body segment; 5. a third body segment; 6. a first taper sleeve; 7. a second taper sleeve; 8. a concave portion.
Detailed Description
The technical scheme of the invention is further described below with reference to the accompanying drawings.
Referring to fig. 1-2, the assembled crucible comprises a crucible base 1, a crucible body detachably arranged above the crucible base 1 (referring to fig. 1, the upper part in fig. 1 is the upper part of the crucible), and a first fixing sleeve with the upper end fixedly sleeved at the lower end of the crucible body, wherein the lower end of the first fixing sleeve is fixedly sleeved on the crucible base 1. By providing the first fixing sleeve, the crucible body and the crucible base 1 can be fixedly sleeved together.
The crucible body comprises at least two split bodies 2, and the at least two split bodies 2 are mutually matched and spliced in a surrounding manner to form the crucible body. In this embodiment, there are two of the split bodies 2. The assembled crucible also comprises a second fixed sleeve fixedly sleeved at the upper end of the crucible body. By providing the second fixing sleeve, the two split bodies 2 can be fixed together in a matched manner. The number of the split bodies 2 can be adjusted according to actual needs.
The crucible base 1 and the crucible body are distributed on the same axis, and the surrounding centers of the two split bodies 2 are positioned on the axis of the crucible body.
The crucible body sequentially comprises a first body section 3, a second body section 4 and a third body section 5 from top to bottom along the vertical direction. The outer peripheral portion of the first body section 3 tapers outwardly in a downward direction; the outer peripheral portion of the third body section 5 tapers outwardly in a downward direction. In this embodiment, the second body section 4 is cylindrical.
The first fixing sleeve is a first taper sleeve 6 with the upper end matched with the outer peripheral part of the third body section 5. In the present embodiment, the upper end of the crucible base 1 is cylindrical, so that although the inner side of the upper end of the first taper sleeve 6 is tapered, the taper of the outer circumference of the third body section 5 is matched; but the inner side of the lower end of the first taper sleeve 6 is cylindrically distributed for matching with the upper end of the crucible base 1. Obviously, the minimum inner diameter of the first cone sleeve 6 should be larger than the maximum outer diameter of the first body section 3. The maximum outer diameter of the third body section 5 is the same as the diameter of the upper cylinder of the crucible base 1.
The second fixing sleeve is a second taper sleeve 7 which is sleeved on the outer peripheral part of the first body section 3 in a matched mode. In this embodiment, the second taper sleeve 7 is higher than the crucible body, and the inner side of the second taper sleeve 7 higher than the upper end of the crucible body is in cylindrical distribution, and the inner diameter of the second taper sleeve is the same as the inner diameter of the crucible body; the inner side of the lower end of the crucible body is in conical distribution and is used for matching the conical shape of the outer side peripheral part of the first body section 3.
The upper end of the crucible base 1 is provided with a first convex ring in an upward convex mode, the lower end of the third body section 5 is provided with a second convex ring in a downward convex mode, the second convex ring is clamped in the first convex ring in a matched mode, and the inner peripheral portion of the first convex ring is in threaded connection with the outer peripheral portion of the second convex ring.
A concave part 8 communicated with the crucible body is arranged in the crucible base 1. The recess 8 is also used for growing an intraocular lens which is located in the recess 8 when the crucible body is removed.
The assembled crucible has the advantages of simple structure, safe use, convenient installation and operation, reusability, improved production efficiency and product quality of grown artificial crystal and reduced production cost.
The working procedure of this embodiment is specifically described below:
the two split bodies 2 are spliced to form a crucible body, a first taper sleeve 6 is sleeved from the upper part of the crucible body, and the crucible body is fixed on the crucible base 1 through the first taper sleeve 6; simultaneously rotating the crucible body to enable the second convex ring to be screwed in the first convex ring, and further fixing the crucible body and the crucible base 1; then, a second cone sleeve 7 is sleeved from the upper part of the crucible body, and the two split bodies 2 are further fixed; raw materials are put into a crucible body, and the whole assembled crucible is put into an artificial crystal growing furnace for crystal growth; after the growth process is finished, the assembled crucible is taken out, the second taper sleeve 7 and the first taper sleeve 6 are taken out upwards, the crucible body is split into two split bodies 2, the split bodies 2 are taken down from the crucible base 1, and then the grown artificial crystal is taken out from the crucible base 1. The detached split body 2 can be recycled.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
