High-efficient platinum system molten glass clarification device Technical Field The utility model relates to the technical field of glass product manufacturing, in particular to a high-efficiency platinum-made molten glass clarifying device. Background In glass manufacturing processes, solution clarification is a critical element, the purpose of which is to remove bubbles and impurities from the solution. However, when the glass solution flows in the pipe, as the flow rate decreases, the components such as alumina in the glass solution are gravity settled when the flow rate decreases due to the density difference, and delamination phenomenon is easily generated, and the delamination not only affects the uniformity of the glass, but also may cause quality problems in subsequent processing. To solve this problem, the prior art generally employs a method of disposing a partition in a pipe to slow down the layering time. Meanwhile, a stirring device is additionally arranged in the subsequent working procedure, and the layered solution is mixed again. However, this solution has the obvious limitation that the stirring process is prone to introducing new bubbles, which is contrary to the original purpose of the clarification process. In order to avoid the generation of bubbles, the stirring equipment and the stirring mode must be optimized finely, which not only increases the equipment cost, but also reduces the production efficiency. Therefore, how to effectively avoid layering phenomenon in the flowing process of glass solution without introducing new bubbles becomes a technical problem to be solved in the current glass manufacturing field. The resolution of this problem will directly affect the quality and production efficiency of the glass product.
