Device for producing bowl material

Abstract

The invention discloses a device for producing a bowl material. The device structurally comprises a cement base, a lower transmission tank, a cement partition layer, a comprehensive heating system, afurnace cylinder, a valve, a secondary chamber, an upper transmission tank, a control cabinet and a power distribution cabinet, wherein the lower part of the cement base is embedded and mounted on theground; the lower transmission tank is arranged on the upper surface of the cement base and is connected through a fixing device; the cement partition layer is arranged at the upper part of the lowertransmission tank; the furnace cylinder is mounted on the upper surface of the cement partition layer; the comprehensive heating system is arranged inside the furnace cylinder; the lower part of thecomprehensive heating system is connected with the lower transmission tank through a transmission device; the valve is arranged at the upper part of the front surface of the furnace cylinder and is electrically connected; the secondary chamber is arranged on the upper surface of the furnace cylinder and is connected through a flange; the upper transmission tank is arranged at the upper part of thesecondary chamber and is connected with the interior of the secondary chamber through a transmission device. Due to adoption of the comprehensive heating system, a single crystal column can be heatedin all directions when being heated in a heating field, so that the growth speed of the single crystal column can be increased, meanwhile, the working efficiency of a user can be effectively improved, and the practicability and the functionality of equipment can be improved.

Description

technical field [0001] The invention relates to the field of machinery, more precisely, it is a device for producing bowl materials. Background technique [0002] With the development of the photovoltaic industry, the amount of monocrystalline silicon is increasing day by day, and the graphite crucible used for pulling monocrystalline silicon is also developing in a large-scale direction. However, large-scale graphite materials have large specifications and high cracking rates, making it difficult to produce, and the utilization rate is only 40%. If the bowl material is produced directly, not only the material cost is saved, but also the structure is stable and the cracking rate is also greatly reduced. But, there is following shortcoming in this bowl material production machine at present: [0003] 1. When controlling the thermal field of the single crystal column, the thermal field heating cannot fully heat the single crystal column, which leads to the slow growth of the...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a device for producing bowl materials, so as to solve the problem in the prior art that when the thermal field control is performed on the single crystal column, the thermal field heating cannot comprehensively control the single crystal column. The heating, which in turn leads to the slow growth of the single crystal column, the equipment needs to spend a lot of time to produce the single crystal column, and its working efficiency is low
