Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, specifically a mixing device for processing lead-free and cadmium-free environmentally friendly coated glass powder. Background Technology

[0002] In traditional glass powder processing, mixing is a crucial step affecting product quality. Currently, most commonly used mixing devices employ a one-time feeding method, adding powder and liquid into the mixing container at once for mixing. However, this method has the following significant drawbacks:

[0003] Adding too much material at once can lead to material accumulation, making it difficult for the powder and liquid to fully contact during mixing. This is especially true for high-density or easily agglomerated glass powder, which can cause localized agglomeration or stratification, affecting the uniformity and performance of the final product. Material accumulation also increases mixing resistance and motor load, prolonging mixing time and potentially causing equipment damage due to overload, thus increasing maintenance costs. Traditional equipment typically requires manual feeding and unloading, which is not only labor-intensive but also generates dust during unloading, posing a health hazard to workers and failing to meet modern environmental protection requirements. Furthermore, material easily adheres to the inner wall of the mixing container, making it difficult to thoroughly clean traditional mixing blades, resulting in raw material waste and affecting the purity of subsequent batches of product.

[0004] To address the aforementioned issues, there is an urgent need to develop a specialized mixing device capable of automatic, uniform feeding, efficient mixing, and convenient unloading, in order to improve the production efficiency and quality stability of lead-free and cadmium-free environmentally friendly glass powder, while reducing labor costs and environmental pollution risks.
