Description

Technical Field

[0001] The utility model relates to the technical field of silicon core furnaces, and particularly relates to a tooling for fixing a quartz outer ring of a water-cooled screen. Background Art

[0002] In order to balance the thermal field temperature of the silicon core furnace, the water-cooled screen, an important component of the existing Czochralski silicon core furnace, needs to be used in combination with a carbon-carbon plate and a quartz outer ring to isolate cold air and hot air convection and balance the thermal field temperature through the carbon-carbon plate and the quartz outer ring. At present, during the actual pulling process of the silicon core, under the condition of long-term high temperature, for each group of silicon cores pulled, the carbon-carbon plate will peel and stick slag due to oxidation heat reaction. In order to ensure the continuous high output and high quality of the silicon core, it is necessary to grind the carbon-carbon plate once when the furnace is out of the furnace for each group of pulled silicon cores, and clean the holes of the seed crystal plate of the water-cooled screen, so as to avoid the silicon core being eaten by slag, adhered and broken due to the falling slag of the carbon-carbon plate and the oxides in the holes of the water-cooled screen during the pulling process, which affects the yield of the silicon core out of the core.

[0003] During the grinding process and the process of replacing the carbon-carbon plate, the quartz ring at the bottom of the seed crystal plate of the water-cooled screen cannot be fixed, and the quartz ring cannot be removed and reinstalled, otherwise it will cause waste of more man-hours. Therefore, during the grinding process, one hand must hold the quartz ring while the other hand grinds the carbon-carbon plate and the holes of the water-cooled screen, which is extremely inconvenient to operate, greatly reducing the man-hour efficiency of the furnace disassembling and cleaning personnel. Moreover, during the grinding process, due to the vibration of the grinding frequency, the quartz ring is extremely easy to be knocked and damaged, resulting in an increase in the material cost.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0028] As Figure 1 and Figure 2 shown, the present utility model discloses a tooling for fixing the quartz outer ring of a fixed water-cooled screen, including a fixing mechanism 100 and a supporting mechanism 200. The fixing mechanism 100 fixes the tooling on any column of the water-cooled screen, and the quartz outer ring is fixedly placed on the supporting mechanism 200.

[0029] The fixing mechanism 100 includes a cylindrical clamping ring. The inner diameter of the clamping ring is adapted to the outer diameter of the column. The clamping ring includes a semi-circular left ring 102 and a right ring 101. One end of the left ring 102 and the right ring 101 is hinged, and the other end is provided with a locking assembly.

[0030] The locking component includes a lock catch 103 provided on the left ring 102 and a pull catch provided on the right ring 101.

By adjusting the positions of the nuts, the position of the pulling rings 106 can be adjusted, and finally the locking degree of the locking component can be adjusted.

[0031] An elastic layer is provided on the inner walls of the left ring 102 and the right ring 101. The provision of the elastic layer avoids damage to the outer wall of the upright column when the clamping ring fixing sleeve is fixed on the upright column. The elastic layer can be a rubber layer or a sponge layer.

[0032] The support mechanism 200 is connected to the right ring 101. The support mechanism 200 includes two groups of strip-shaped support components, and both groups of support components are arranged along the radial direction of the clamping ring.

By using a material with a large frictional force or by adjusting the size of the sliding groove 202, the wall of the sliding groove 202 is made to be in close contact with the movable wall 203, so as to adjust the sliding friction pair between the movable wall 203 and the sliding groove 202, such that the sliding of the movable wall 203 on the sliding groove 202 has a certain resistance. A groove 204 for receiving the quartz outer ring is provided at the top of the movable wall 203. The quartz outer ring is placed in the groove 204 to achieve its support and fixation.

[0034] The fixing mechanism 100 is made of aluminum alloy material, which is light in weight and is beneficial to reducing the weight of the tooling. The support mechanism 200 is made of polypropylene (PP) material, which is not easy to damage the quartz outer ring and can avoid polluting the heat field components and silicon materials of the silicon core furnace. The support mechanism 200 is retractable, which is convenient for the carrying and disassembly of the tooling.

[0035] When performing carbon-carbon plate grinding and cleaning the holes of the water-cooled screen seed crystal plate, open the locking component to open the clamping ring. Sleeve the clamping ring on the water-cooled screen upright column. Pull out the movable wall 203 of the support component from the sliding groove 202. Adjust the height of the tooling and the length of the extension of the movable wall 203, so that the quartz outer ring is fixedly placed in the grooves 204 of the two movable walls 203. Then lock the locking component to fix the clamping ring on the upright column, thereby achieving the support and fixation of the quartz outer ring.

[0036] The utility model is connected to the water-cooled screen column and provides a placement for the quartz outer ring, effectively fixing the quartz outer ring, avoiding the risk of the quartz outer ring falling during the grinding process, effectively reducing the possibility of the quartz outer ring of the water-cooled screen being knocked and damaged during the silicon core drawing process.

While saving manpower and drawing workers, it increases the finished product efficiency, the number of silicon core rods is improved to a certain extent, and equipment process guarantee is provided for drawing silicon core rods within the effective time.
