Problems solved by technology

When molten elemental silicon is solidified under supercooled conditions, silicon atoms are arranged in the form of diamond lattices to form many crystal nuclei. If these crystal nuclei grow into crystal grains with different crystal plane orientations, these crystal grains combine to crystallize into polycrystalline silicon. In the production process of polysilicon, the stains and dust attached to the surface of polysilicon need to be cleaned to improve the purity of polysilicon and the quality of finished products. The existing cleaning equipment has a low degree of automation, high manual labor intensity, poor cleaning effect, and troublesome cleaning process. strenuous

Abstract

The invention discloses an automatic polycrystalline silicon washing device which comprises a washing rack, a drying rack, a washing hood, a drying hood, a conveyor belt, a conveyor belt support sideplate, a plurality of washing baskets, a washing basket carrying device and a plurality of drying fans; the drying rack is connected with one end of the washing rack; the drying hood is transversely arranged at the upper end of the drying rack; the washing hood is transversely arranged at the upper end of the washing rack; the washing hood communicates with the drying hood; and the end, far away from the drying rack, of the washing rack extends out of the washing hood to be provided with a feeding platform. According to the automatic polycrystalline silicon washing device, the washing basket carrying device is cooperated with the washing baskets, a plurality of washing grooves and the conveyor belt to realize automatic feeding, automatic washing and automatic drying, improve the polycrystalline silicon washing efficiency and lower the manual labor intensity; and purified water is filled in the washing grooves, and the washing quality is improved through ultrasonic washing.

Description

【Technical field】 [0001] The invention relates to the technical field of polysilicon production equipment, in particular to the technical field of polysilicon cleaning devices. 【Background technique】 [0002] Polysilicon is a form of elemental silicon. When molten elemental silicon is solidified under supercooled conditions, silicon atoms are arranged in the form of diamond lattices to form many crystal nuclei. If these crystal nuclei grow into crystal grains with different crystal plane orientations, these crystal grains combine to crystallize into polycrystalline silicon. In the production process of polysilicon, the stains and dust attached to the surface of polysilicon need to be cleaned to improve the purity of polysilicon and the quality of finished products. The existing cleaning equipment has a low degree of automation, high manual labor intensity, poor cleaning effect, and troublesome cleaning process. strenuous. 【Content of invention】 [0003] The purpose of th...
