AI Technical Summary
Traditional quartz crucible molds are prone to deform at high temperatures. During use, the inner wall of the steel film expands severely, making it difficult to pull out the mesh screen. The isolation cover needs to be cut and welded, wasting resources and increasing the operating risk, and easy to damage.
A steel membrane auxiliary device is designed, including a mesh screen, an extractor body, an installation groove, an unplugged wrench and a rotary handle. Through threaded connections and through-hole structures, it allows for the rapid replacement of the damaged mesh screen and reduces manpower and material consumption.
It realizes rapid replacement of mesh screens, saves time, reduces the risk of mold damage, and improves the efficiency and stability of steel molds.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of quartz crucible manufacturing and relates to a steel film auxiliary device. Background Art
[0002] Quartz crucible is an important consumable component in the production of photovoltaic single crystal silicon. In the production process of single crystal silicon wafers, quartz crucible is a consumable container for pulling single crystal silicon rods. It is used to hold molten silicon liquid and is a key consumable for crystal pulling.
[0003] With the continuous promotion of clean energy, solar photovoltaic power generation has become a booming industry in recent years, and the required monocrystalline silicon is in short supply. Traditional quartz crucibles use graphite crucible molds, but the high cost, easy to break and peel, easy to deform make it unable to meet the higher requirements of quartz crucibles. In recent years, porous steel molds have obviously attracted the attention of the industry. The steel mold is made of alloy material, and the structural characteristics make the performance more stable, not easy to deform, environmentally friendly and not fall off.
[0004] When the steel film is under high temperature, the inner wall of the steel mold expands severely, and after using the water-cooled integrated mold, the mesh screen cannot be pulled out. If the mesh screen needs to be removed, the outermost isolation cover must be cut open, and then the mesh screen is poked out, and then the isolation cover is welded, which wastes manpower, material resources and financial resources; at the same time, the mold may be damaged during the operation, making the mold unusable. Utility Model Content
[0005] The utility model aims to solve the above problems in the prior art and proposes a steel film auxiliary device which can quickly replace the mesh screen in the steel film.
[0006] The purpose of the utility model can be achieved through the following technical solutions: a steel film auxiliary device, characterized in that it includes a mesh screen and a remover body, the remover body is provided with a mounting groove, the mesh screen is arranged at the bottom of the mounting groove, the mesh screen removal body is provided with a removal wrench, the removal wrench is threadedly connected to the mounting groove, and the removal wrench is provided with a rotating handle.
[0007] In the above-mentioned steel film auxiliary device, a through hole connected to the mounting groove is arranged at the bottom of the remover body, and the diameter of the mounting groove is larger than the diameter of the through hole.
[0008] In the above-mentioned steel membrane auxiliary device, the mesh screen is interference fit with the installation groove.
[0009] In the above-mentioned steel film auxiliary device, the upper end of the installation groove is provided with an internal thread, and the end of the extraction wrench is provided with an external thread matching the internal thread.
[0010] In the above-mentioned steel film auxiliary device, the rotating handle is a butterfly-shaped handle or a handle of other shapes.
[0011] Compared with the prior art, the utility model cooperates with the extractor body and the mesh screen to be placed in the vacuum exhaust hole of the steel mold during use. When the mesh screen is damaged, it is only necessary to use a puller wrench to cooperate with the extractor body through the thread to pull out the entire extractor, and then remove the puller wrench, replace the mesh screen in the installation groove, and then insert the extractor body into the vacuum exhaust hole. In this way, when the mesh screen is damaged, it is convenient to quickly replace the mesh screen, which saves time and is conducive to the promotion and use of new integrated molds. BRIEF DESCRIPTION OF THE DRAWINGS
