Description

Technical Field

[0001] The utility model relates to the technical field of quartz ingot production and manufacturing, in particular to a quartz ingot preparation device. Background Art

[0002] With the rapid development of my country's optical communication industry, semiconductor industry, and solar photovoltaic industry, the domestic quartz products industry has flourished. Quartz products produced by different processes include quartz tubes, quartz rods, quartz plates, quartz ingots, etc.

[0003] The preparation of quartz ingots mainly adopts the gas refining method, which uses a hydrogen-oxygen flame as a heat source to melt quartz sand through a burner. The molten quartz is sprayed onto the target holder carrying the bottom ingot, and rotates and descends at a uniform speed to ensure that the target holder surface always maintains a constant distance from the burner and is always in the high-temperature zone. The temperature in the high-temperature zone can reach 1700°C. Due to the appropriate temperature field from high to low in the furnace, the molten quartz gradually cools down to become a columnar quartz ingot after leaving the high-temperature zone. At present, the lifting motor and the self-rotating motor in the drive device are exposed to high temperatures for a long time, causing the oil volume in the motor to expand and the air vent to be blocked and unable to vent, resulting in a high oil leakage rate and high maintenance frequency. At the same time, the high temperature environment causes the motor to heat up, the heat load is large, and the coil is easily burned, resulting in self-rotation and lifting failures, resulting in a shortened equipment life and increased production losses.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention that does not depart from the spirit and scope of the technical solution of the present invention should be included in the scope of protection of the present invention.

[0020] like Figure 1 As shown, the utility model proposes a quartz ingot preparation device, which consists of four parts: an insulation chamber 1, a height adjustment mechanism 4, a supporting mechanism 2 and a driving mechanism 3; the supporting mechanism 2 is arranged in the insulation chamber 1, and is used to carry the quartz ingot, the height adjustment mechanism 4 is connected to the supporting mechanism 2, and is used to adjust the height of the quartz ingot, and the driving mechanism 3 is connected to the supporting mechanism 2, and is used to drive the quartz ingot to rotate.

[0021] Specifically, the insulation chamber 1 is composed of an inner insulation layer 11 and an outer insulation layer 11. There is a gap between the inner insulation layer 11 and the outer insulation layer 11. Insulation cotton 12 is provided in the gap to provide insulation during the preparation of the quartz ingot. The height adjustment mechanism 4 includes a lifting motor 42 and a bracket. The lifting motor 42 is fixed to the side wall of the insulation chamber 1. The bracket is fixedly installed on the inner wall of the insulation chamber 1. A screw is fixedly installed in the bracket. The output end of the lifting motor 42 is connected to the screw through a transmission mechanism. The transmission mechanism is preferably a gear transmission or a synchronous belt transmission to ensure its stability during transmission to ensure a stable operating speed. The supporting mechanism 2 includes a support platform 24, a target holder 23 and a bottom ingot 22. The support platform 24 is located on the left side of the bracket and is arranged in the horizontal direction. The right side of the bracket is installed on the screw through a threaded connection. The lifting motor 42 drives the screw to rotate forward or reverse, causing the support platform 24 to move up and down on the screw to adjust the height of the support platform 24. The target holder 23 is mounted on the left side of the support platform 24 and connected to the support platform 24 via a bearing, enabling it to rotate about its own central axis. The bottom mass 22 is fixed to the target holder 23 and serves as a reference during the melting process of the quartz mass. The drive mechanism 3 includes a rotation motor 31, which is fixedly mounted outside the holding chamber 1 and positioned so as not to interfere with the lifting motor 42. The rotation motor 31 is connected to the target holder 23 via a transmission mechanism, preferably a gear drive or synchronous belt drive to ensure a stable transmission ratio and thus a stable rotation rate.

[0022] Preferably, the quartz ingot preparation device also includes a controller, and the lifting motor 42 and the rotation motor 31 are both connected to the controller, which is used to synchronously control the speed of the lifting motor 42 and the rotation motor 31, so that the lifting speed of the support platform 24 and the rotation speed of the target holder 23 can be controlled according to the lifting and rotation speed ratio in the design requirements, so as to adapt to the different preparation process requirements of different quartz ingots, thereby improving the application versatility of the entire quartz ingot preparation device.

[0023] Preferably, an observation window 13 and a quartz spray port are provided on the insulation chamber 1. The positions of the observation window 13 and the quartz spray port do not interfere with each other. The observation window 13 is located below the quartz ingot, corresponding to the position of the target holder 23, and is used to observe the rotation of the target holder 23 to ensure the stable completion of the entire preparation process.

[0024] Working principle:

[0025] During use, the molten quartz is sprayed onto the target holder 23 carrying the bottom mass 22 through a burner. At the same time, the controller controls the start of the rotation motor 31 and the lifting motor 42, and controls the rotation speed of the rotation motor 31 and the lifting motor 42 according to the speed ratio required by the design, so that the bottom mass 22 on the target holder 23 rotates and descends at a uniform speed to prepare the quartz mass.

[0026] The utility model arranges the target holder 23 in the insulation chamber 1 and carries it through the support platform 24, and at the same time connects the target holder 23 to the rotation motor 31 arranged outside the insulation chamber 1 to drive the target holder 23 to rotate; connects the carrying platform to the lifting motor 42 arranged outside the insulation chamber 1 to drive the support platform 24 to perform lifting movement. Under the premise of ensuring the normal preparation of the quartz ingot, the driving motor and the lifting motor 42 can be isolated from the high temperature environment, thereby improving the service life of the two motors and reducing production losses.
