Description

Technical Field

[0001] This utility model relates to the field of monocrystalline silicon manufacturing technology, specifically to a novel feeder device. Background Technology

[0002] In the photovoltaic industry, raw material refeeding is required during crystal pulling. The raw material carrier is the feeder, which is currently commonly made of quartz. The feeder barrel (main body) is made of quartz, the bottom bowl is made of quartz / ceramic, and the connecting rod in the middle is made of stainless steel. The main body of the feeder is made of quartz, which is relatively brittle and can be damaged by impacts during use. The average number of uses is around 300, and the cost of each feeder is relatively high. Due to the frequency of damage, the cost pressure is significant. During raw material refeeding, the risk of breakage of the quartz feeder increases with the number of uses. Broken quartz can fall into the silicon liquid, causing crystal pulling slag adhesion and wire breakage, affecting crystal pulling. In addition, there is a risk that the connecting rod may fall into the crucible after the quartz feeder breaks, rendering the raw material unusable.

[0003] Therefore, it is necessary to provide a new type of feeder device to solve the above-mentioned technical problems. Utility Model Content

[0022] Example 1

[0023] Reference Figures 1-4 The first embodiment of this utility model provides a novel feeder device, including a feeder, characterized in that the feeder is divided into a first part 101 and a second part 102, which are connected by a fixing component 103. The fixing component 103 includes an upper fixing member 104 and a lower fixing member 105, which are hinged together. The connection between the first part 101 and the second part 102 is located in the fixing component 103. Specifically, the first part 101 is a quartz feeder made of quartz material, and the second part 102 is a tetrafluoroethylene feeder made of a polymer compound. Because the quartz in the quartz feeder has a melting point of 1750℃ and a hardness of 7, it can withstand the temperature above the screen inside the single crystal furnace during the feeding process. The liquid surface temperature is about 1450℃. The temperature gradient increases from near the water-cooled screen inside the single crystal furnace, and the temperature decreases. At a distance of 1m from the liquid surface, the temperature drops to about 250℃. Materials with relatively poor high-temperature resistance can be used as substitutes. The first part 101 is the lower half of the feeder, and the second part 102 is the upper half of the feeder.

[0024] The lower half of the feeder uses the original material (quartz), while the upper half, above 1m, uses PTFE instead. The two are joined using a stop-joint connection to ensure that their outer and inner diameters are consistent. The upper PTFE part can be used more than 2000 times, while the lower quartz part can be used for the same number of times (300 times). The price of the lower quartz part is 1 / 3 of the original price of the all-quartz part, while the price of the PTFE part is the same as that of the quartz part, which means the cost is reduced by 60%. This greatly reduces the technical problem of high feeder breakage frequency during the feeding process.

[0025] Because the outer edges of the first part 101 and the second part 102 have round holes, they are fixedly connected by bolts to enhance their stability. To ensure a tight seal at the connection, a heat-resistant steel sealing ring is used between them. A fixing component 103 is fitted onto the outside of the connection between the fixed first part 101 and the second part 102. This fixing component 103 consists of an upper fixing member 104 and a lower fixing member 105, both of which are semi-circular in shape and connected by a hinge. Since both the upper fixing member 104 and the lower fixing member 105 have internal grooves 106, the connection between the first part 101 and the second part 102 of the feeder is simply achieved by... The fixing component 103 can be fixed to the feeder by embedding it into the groove 106. The upper fixing component 104 and the lower fixing component 105 are closedly connected by a locking device 107. The locking device 107 is a one-button quick-locking clamp, which consists of a handle 108 and a fixing seat 109. The handle 108 is installed on the outer surface of the upper fixing component 104, and the fixing seat 109 is installed on the lower fixing component 105. The fixing seat 109 and the handle 108 are correspondingly adapted. When opening, the locking device 107 can be disengaged from the fixing seat 109 simply by lifting the handle 108. When locking, it can be locked with a single press. This not only prevents safety accidents caused by improper operation, but also makes installation and maintenance very convenient.

[0026] In summary, this utility model employs a method of splicing different materials, making the upper part of the feeder more resistant to breakage and increasing its number of uses. If the lower quartz section is damaged, only the quartz section needs to be replaced, while the upper PTFE section can be reused. This significantly reduces the technical problem of high feeder breakage frequency during feeding and lowers the feeder cost.
