An electrode protection device capable of reducing consumption and preventing sparking

Abstract

This utility model relates to an electrode protection device that reduces energy consumption and prevents sparking, comprising a base, an upper cylinder, an inner cylinder, and a cover. The base is hollow with an open upper end, and a column is located inside. The column is also hollow with an open upper end. The bottom of the base has a boss-shaped cavity, the upper end of which connects to the interior of the column. Mounting platforms are provided on the upper ends of the inner walls of both the base and the column. Abutment blocks are provided on the lower ends of both the upper and inner cylinders. The upper cylinder is mounted on the upper end of the base via the mounting platforms and abutment blocks, and the inner cylinder is mounted on the upper end of the column via the mounting platforms and abutment blocks. The cover is threaded to the upper end of the upper cylinder, and the inner cylinder is threaded to the inner cylinder. The boss-shaped cavity and the inner cavity of the column enclose a ceramic sheath protecting the copper electrode, preventing dust from the bottom from reaching the copper electrode and causing sparking. The space between the inner wall of the base and the column is filled with adhesive-based felt, which, under the sealing effect of the annular cover, maintains a relatively sealed interior, increasing insulation performance and reducing energy consumption.

Description

Technical Field

[0001] This utility model belongs to the field of electrode protection technology for single crystal furnaces, specifically, it relates to an electrode protection device that can reduce energy consumption and prevent sparking. Background Technology

[0002] In a single-crystal furnace, the graphite electrode acts as a conductor, responsible for providing sufficient current to ensure the power supply during single-crystal growth. During single-crystal silicon production, heating the graphite electrode rapidly increases and maintains the furnace temperature, thereby guaranteeing the quality and efficiency of the single crystal.

[0003] The existing electrode protective sleeves for single crystal furnaces cannot effectively protect the copper electrodes. During the installation of the hot zone of the single crystal furnace, dust can easily drift into the copper electrodes, which can easily cause sparking accidents during later use. Utility Model Content

[0004] In order to overcome the problems existing in the background technology, the present invention provides an electrode protection device that can reduce energy consumption and prevent arcing.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An electrode protection device for reducing energy consumption and preventing sparking includes a base, an upper cylinder, an inner cylinder, and a cover. The base is hollow with an open upper end and contains a column. The column is also hollow with an open upper end. The bottom of the base has a boss-shaped cavity, the upper end of which connects to the interior of the column. Mounting platforms are provided on the upper ends of the inner walls of both the base and the column. Abutment blocks are provided on the lower ends of both the upper and inner cylinders. The upper cylinder is mounted on the upper end of the base via the mounting platforms and abutment blocks, and the inner cylinder is mounted on the upper end of the column via the mounting platforms and abutment blocks. The cover is threaded to the upper end of the upper cylinder. The cover has an inner ring with threads on its inner wall, and the inner cylinder is connected to the inner cylinder via these threads.

[0007] Furthermore, the column is a cylinder.

[0008] Furthermore, the column and the base are integrally formed.

[0009] Furthermore, the base, upper cylinder, inner cylinder, and cover are made of high-purity quartz.

[0010] Furthermore, the space between the outer wall of the column and the inner wall of the base is filled with adhesive-based felt.

[0011] The beneficial effects of this invention are as follows: Made of high-purity quartz material, it effectively reduces usage costs and extends service life; the protruding cavity and the internal cavity of the column encase a ceramic sheath protecting the copper electrodes, preventing dust from the bottom from drifting onto the copper electrodes and causing sparking accidents; the adhesive-based felt filling between the inner wall of the base and the column, sealed by the annular cover plate, maintains a relatively airtight interior, increasing insulation performance and reducing power consumption. Overall, it has low usage costs, reduces power consumption, prevents sparking, and allows for the reuse of waste felt. Attached Figure Description
