Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of paint mixing kettle, more specifically, it relates to paint mixing kettle. BACKGROUND

[0002] In the production process of paint, it is usually necessary to use a paint mixing kettle to mix and stir the raw materials. The existing paint mixing kettle does not have a structure for filtering powdery raw materials during use. When powdery raw materials (such as pigments and fillers) are added to the paint mixing kettle, they may form lumps. If these lumps are directly added to the paint mixing kettle, they may not be fully dissolved or dispersed, which may affect the quality of the paint. In addition, the existing paint mixing kettle usually has a heat preservation chamber to ensure the quality and production efficiency of the paint. The heat preservation chamber contains circulating hot medium (such as hot water or hot oil). The hot medium may carry impurities during circulation, which may come from pipe corrosion, medium aging, or external pollution. As the hot medium circulates, the impurities gradually enter the heat preservation chamber and may deposit on the inner wall of the heat preservation chamber or in the circulation system. Long-term accumulation of impurities not only reduces the heat transfer efficiency of the hot medium and affects the heat preservation effect, but also may block the heat preservation chamber.
