Description

Technical Field

[0001] The utility model relates to the field of transformer casting, in particular to a transformer static mixing casting device. Background Art

[0002] The transformer static mixing and pouring device is a critical piece of equipment used in the production of power equipment such as transformers. Its primary function is to mix raw materials such as resin and curing agent in a specific proportion and perform the pouring process under vacuum or a specific environment to ensure product quality and performance. The device automatically adds raw materials such as resin, curing agent, and filler to their respective premixing tanks according to a preset ratio. A stirring device then thoroughly agitates the raw materials in the premixing tanks. The mixed material is then subjected to a vacuum negative pressure treatment to remove air bubbles and impurities. A metering pump then delivers the mixed material to a static mixer at a set ratio and flow rate. In the static mixer, the materials are further mixed and poured directly into a mold. After pouring, the materials gradually solidify and form in the mold, forming the desired product structure.

[0003] The internal structure and design of existing static mixers determine their mixing performance and application range. Different static mixers are required for conveying and pouring to meet different operational requirements. Replacing a static mixing and pouring device in the prior art requires frequent tightening of multiple bolts, making installation and disassembly inconvenient. Therefore, those skilled in the art have provided a transformer static mixing and pouring device to address the issues raised in the background art. Utility Model Content
