Abstract

The invention discloses a quartz feeding system for transversely stacking polycrystalline silicon raw materials and a lossless adding method, the quartz feeding system comprises a hot melting box, the left side of the hot melting box is fixedly connected with a fixing plate, and the top of the fixing plate is provided with a reciprocating feeding mechanism; the reciprocating feeding mechanism comprises a fixing seat fixedly connected to the top of the fixing plate, a cross rod is slidably connected to the top of the fixing plate, the right end of the cross rod penetrates through the fixing seat and extends to the outside of the fixing seat, the outer surface of the cross rod is slidably connected with the inner surface of the fixing seat, and a fixing column is fixedly connected to the left side of the top of the cross rod. The invention relates to the technical field of quartz charging. According to the quartz feeding system for transversely stacking the polycrystalline silicon raw materials and the lossless feeding method, through the arrangement of the switching mechanism, regular free blanking of the quartz raw materials is achieved, meanwhile, through collection treatment of the material receiving box, the quartz particle raw materials are prevented from being spilled to the outside, the loss of the raw materials is reduced, and the production cost is reduced.

Description

Technical field [0001] The present invention relates to the field of quartz feeding, and is specifically a quartz feeding system and a lossless addition method of a transverse code polycrystalline silicon feedstock. Background technique [0002] Polysilicon is a form of single textile silicon. When the molten monohydric silicon is solidified under extra cold conditions, the silicon atom is arranged in the form of a diamond crystal, such as such a crystal nucleus to be different, and these crystal grains are combined, crystalline into polysilicon. . The polysilicon material is a direct material that produces single crystal silicon, and is an electronic information base material for contemporary manual intelligence, automatic control, information processing, photoelectric conversion and other semiconductor devices. The cornerstone of the microelectronics building. [0003] Polysilicon raw materials generally refer to quartz, then heat the quartz heat, then draw, form polysilicon an...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a quartz feeding system and a non-destructive adding method for laterally stacking polysilicon raw materials, which solves the problem that the existing quartz feeding system needs to manually add a small amount of material, and wait for the quartz to be completely melted before adding. It is time-consuming and labor-intensive, and when manually feeding, quartz particles are easy to spill out to the outside, resulting in a certain degree of waste and loss, and when transporting the entire hot-melt device, it is difficult to achieve light weight due to the heavy weight of the hot-melt device. Handle with care, the base of the hot melt device is prone to rigid collision with the ground, and it is easy to damage the base and the ground
