Silicon core furnace capable of realizing continuous production, and using method

Abstract

The invention discloses a silicon core furnace capable of continuous production, and a use method. The silicon core furnace comprises: a lower furnace body internally provided with a silicon core drawing device, wherein the upper part of the lower furnace body is provided with a first partition plate capable of being opened and closed, at least two upper furnace bodies detachably connected with the lower furnace body; and an environment control device for carrying out environment control on the lower furnace body and the upper furnace body which is not provided with the lower furnace body. According to the invention, the furnace body is divided into two detachable parts, in the silicon core drawing process, environment control is conducted on one upper furnace body, and compared with the prior art that the furnace body is divided into two fixedly-connected parts, the mode of the invention can solve the problem of time cost (the whole silicon core furnace drawing process needs about 5 h, the heating material melting process lasts for about 30 min, and the furnace dismounting and replacing process lasts for about 30 min), and can solve the problems of energy cost and resource cost waste (reducing empty burning of the raw material rod in the silicon core drawing device and effectively utilizing the lower half part of the raw material rod).

Description

technical field

[0001] The invention relates to a silicon core furnace capable of continuous production and a use method. Background technique

[0002] With the global consensus on green energy, the photovoltaic industry has developed rapidly. As an upstream product in the photovoltaic industry chain, polysilicon is in short supply. Powerful business giants at home and abroad have invested huge sums of money in the polysilicon industry. The scale of development is getting larger and larger. Silicon The core furnace is an important link in the polysilicon production chain, and the demand is also increasing.

[0003] The currently used silicon core furnaces all produce silicon cores intermittently. The operation time is long, the furnace is loaded frequently, the workload of the operators is large, and the loss of silicon materials is also large due to frequent operation. In the face of huge market demand, manpower, material resources and energy consumption are huge. Therefor...
