As shown in fig. 1, the magnetic field supporting device disclosed by the utility model is used for a single crystal furnace to support a magnetic pole 300, and comprises supporting blocks 200, wherein the supporting blocks 200 are arranged on the outer side of a furnace body 100 of the single crystal furnace and distributed along the circumference of the furnace body 100, and the supporting blocks 200 are symmetrically distributed along the symmetry plane of the furnace body 100, and the symmetry plane is a plane passing through the axis of the furnace body 100; the magnetic pole 300 is disposed on the supporting block 200, and a plane formed by a side of the supporting block 200 away from the ground is perpendicular to the axis of the furnace body 100.
The magnetic field supporting device provided by the utility model comprises the supporting blocks 200 distributed along the circumference of the furnace body 100 of the single crystal furnace, the supporting blocks 200 are symmetrically distributed along the symmetrical plane of the furnace body 100, and meanwhile, the plane formed by one side, far away from the ground, of the supporting blocks 200 is vertical to the axis of the furnace body 100, namely, the upper surface of the supporting blocks 200 is parallel to the ground, so that when the magnetic poles 300 are placed on the supporting blocks 200, the magnetic poles can be stably placed.
The magnetic field supporting device is installed on the outer wall of the furnace body 100 of the single crystal furnace, so that the installation of the magnetic field is simplified, and the installation and the disassembly of the magnetic field device are simpler and more convenient. When one single crystal furnace is idle, the magnetic pole 300 placed on the magnetic field supporting device of the single crystal furnace can be transferred to other single crystal furnaces for use, the purpose of sharing the magnetic pole 300 is achieved, the installation cost of the magnetic field device is saved, and the photovoltaic industry popularization and use value is achieved.
In order to make the connection of the support blocks 200 with the furnace body 100 more stable, the support blocks 200 are welded with the furnace body 100 by welding.
The number of the supporting blocks 200 may be set to one, i.e., one supporting block 200 is symmetrically distributed along the symmetry plane of the furnace body 100. In view of saving materials and reducing cost, the volume of the supporting blocks 200 is reduced under the effect that the supporting blocks 200 can support the magnetic poles 300, the supporting blocks 200 can be arranged in a plurality, the plurality of supporting blocks 200 are distributed along the circumference of the furnace body 100, and the number of the supporting blocks 200 is equal at the left side and the right side of the symmetry plane. To ensure stability of the magnetic pole 300, the number of the supporting blocks 200 is set to be an even number of four or more.
As shown in fig. 2, in an embodiment of the present utility model, the distance between the side of the supporting block 200 away from the ground and the bottom of the furnace body 100 is 380mm-410mm, so that interference between the supporting block 200 and the second floor caused by insufficient distance between the supporting block 200 and the bottom of the furnace body 100 is avoided, and on the other hand, too small effect of the magnetic field generated by the magnetic pole 300 on the melt caused by too high position of the magnetic pole 300 relative to the furnace body 100 of the single crystal furnace is avoided, so that the oxygen content in the melt cannot be effectively reduced.
In order to ensure the supporting function of the supporting block 200 on the magnetic pole 300, the magnetic pole 300 is integrally positioned on the supporting block 200, the length of the supporting block 200 is set to be a, the distance between one side of the magnetic pole 300, which is close to the furnace body 100, and the furnace body 100 is set to be b, and the thickness of the magnetic pole 300 is set to be c, wherein a is larger than or equal to b+c, namely, one side of the magnetic pole 300, which is far away from the furnace body 100, is ensured to be positioned between one side of the supporting block 200, which is far away from the furnace body 100, and the furnace body 100.
The utility model also discloses a magnetic field device which is arranged outside the furnace body 100 of the single crystal furnace and comprises a magnetic pole 300 and a magnetic field supporting device according to any one of the above; a blind plate 101 is arranged on a furnace body 100 of the single crystal furnace, and a stand column 102 is arranged on the outer side of the furnace body 100. Because the magnetic field supporting device has the above effects, the magnetic field device comprising the magnetic field supporting device has corresponding effects, and the description thereof is omitted herein.
In an embodiment of the present utility model, to avoid interference components, such as the column 102, outside the furnace body 100 of the single crystal furnace, the magnetic pole 300 is configured as a non-closed ring structure with a notch, and the magnetic pole 300 is coaxially arranged with the furnace body 100, where the column 102 is disposed. In addition, when the magnetic pole 300 is placed, the position of the blind plate 101 is noted, and the blind plate 101 is aligned to the notch to avoid interference between the magnetic pole 300 and the blind plate.
In order to ensure that the whole device is stable, the magnetic poles 300 and the supporting blocks 200 are symmetrically distributed along the symmetrical plane of the furnace body 100, so that the stability of the magnetic poles 300 on the supporting blocks 200 is ensured, and no deflection occurs.
The central angle corresponding to the notch of the magnetic pole 300 is set to be greater than or equal to 60 degrees so as to avoid interference components around the furnace body 100 of the single crystal furnace as much as possible. The interference member should be located at a middle position of the angle of the magnetic pole 300.
In order to ensure the effect of the magnetic field generated by the magnetic pole 300 on the melt in the single crystal furnace body 100, the lorentz force applied to the melt is limited by the distance between the magnetic pole 300 and the furnace body 100, and in one embodiment of the utility model, the distance between the side of the magnetic pole 300, which is close to the furnace body 100, and the furnace body 100 is 50mm-200mm.
