High voltage electropulse breakup reaction tank for line production

Abstract

The invention discloses a reaction tank adopting high voltage electropulse in-water electric discharge to break up polycrystalline silicon rods. The reaction tank comprises a guiding fixing barrel, a sieve, electrode structures, a water tank and a conveying belt. Each electrode structure comprises an electrode frame plate, an electrode stem and an electrode head, wherein the electrode frame plate is provided with an adjusting groove so that the electrode spacing can be guaranteed, the electrode height can be adjusted and the demand for breakup of silicon rods which are different in diameter can be met. The electrode stems are wrapped with insulating layers correspondingly so that the situation that electric discharge occurs among the electrode stems, current leaks and consequently energy loss is caused can be prevented. A stainless steel material is used as an electrode material so that the current endurance capacity and mechanical strength needed by a breakup electrode can be guaranteed, and meanwhile loss of the electrode due to electric discharge is low. Holes slightly larger than expected broken polycrystalline silicon blocks are formed in the sieve, so that broken finished products are exposed and discharged and conveyed to the next stage by the conveying belt.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electric pulse crushing, and more specifically relates to a high-voltage electric pulse crushing reaction tank used for assembly line operation. Background technique [0002] As the main raw material for photovoltaic power generation, polysilicon production is increasing year by year with the development of photovoltaic industry. Polysilicon production usually uses chemical methods to produce silicon rods first, and the polysilicon rods can be used to manufacture various photovoltaic products after being crushed. my country's polysilicon industry has long relied on manual crushing of polysilicon rods. With the increase in polysilicon production, manual crushing has been unable to meet the needs of production. Using high-voltage pulse water discharge to crush polysilicon rods has the advantages of no pollution, no dust, and high efficiency, and has a good application prospect in the polysilic...
