Embodiment 1
[0039] This embodiment is used to prepare a hollow silicon core with a square cross section and a silicon core assembly thereof.
[0040] as attached figure 1 , 3 , 4 and 7, the hollow silicon core of this embodiment is formed by splicing four strip-shaped vertical silicon plates 2 . In addition to the hollow silicon core formed by splicing four strip-shaped vertical silicon plates 2, the silicon core assembly also includes an upper and lower locking mechanism for the silicon core. This embodiment adopts a fixing base 5 with a square cross section, and the lower parts of the four vertical silicon plates 2 are attached to the outer surfaces of the square fixing base 5, so that each vertical silicon plate 2 is joined end to end to form a hollow square. A certain gap can also be left between adjacent vertical silicon plates 2 , and the gap will be gradually bridged as the crystallization process progresses. A fixing sleeve 3 is also provided on the outside of the fixing seat 5...
Embodiment 2
[0045] as attached Figure 8 As shown, the same as in Example 1, it is also used to prepare a hollow silicon core with a square cross-section and a silicon core assembly thereof. The only difference from Embodiment 1 is that this embodiment adopts another upper locking mechanism.
[0046] The upper locking mechanism includes two intersecting locking bars, namely the front and rear vertical silicon plate locking bars 12 and the left and right vertical silicon plate locking bars 13 . The positions corresponding to the vertical silicon plates 2 on the lower surface of the locking strip are respectively provided with card slots, and the upper ends of the four vertical silicon plates are respectively inserted into the corresponding card slots, thereby fastening the upper ends of the hollow silicon cores. . Then connect the two hollow silicon cores together by means of a silicon plate. It should be noted that, in order to improve the connection firmness of the two intersecting lo...
Embodiment 3
[0049] as attached figure 2 , 5 As shown in and 6, this embodiment is a modification of the lower locking mechanism disclosed in embodiment 1. A silicon strip fixing groove is provided on the upper end surface of the fixing seat 5, and the shape of the silicon strip fixing groove is set as a required polygon. Insert the lower end of the hollow silicon core into the fixing groove of the silicon bar. Of course, the socket 6 can also be used instead of the silicon strip fixing groove, so as to insert the corresponding round silicon core 14 or square silicon strip.
[0050] In order to improve the stability of the round silicon core 14 or the square silicon strip in the socket 6 or the silicon strip fixing groove, a locking hole 7 penetrating to the jack 6 or the silicon strip fixing groove can be set on the outer peripheral surface of the fixing seat 5, Fasten by tightening the bolts.
[0051] Or the sheath 9 is sleeved on the outer peripheral surface of the fixed seat 5, an...
