Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing technology, and in particular to a high-efficiency platinum molten glass refining device. Background Technology

[0002] In glass manufacturing, solution clarification is a crucial step, aiming to remove air bubbles and impurities from the solution. However, as the molten glass flows through pipes, components such as alumina in the solution, due to density differences, undergo gravitational sedimentation as the flow rate decreases, easily leading to stratification. This stratification not only affects the uniformity of the glass but can also cause quality problems in subsequent processing. To address this issue, existing technologies typically employ baffles in the pipes to slow down the stratification process. Simultaneously, a stirring device is added in a subsequent process to remix the stratified solution. However, this solution has significant limitations: the stirring process easily introduces new air bubbles, contradicting the original purpose of the clarification step. To avoid bubble generation, the stirring equipment and method must be meticulously optimized, increasing equipment costs and reducing production efficiency. Therefore, effectively preventing stratification during molten glass flow without introducing new air bubbles has become a pressing technical challenge in the glass manufacturing industry. Solving this problem will directly impact the quality and production efficiency of glass products. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency clarification device for molten platinum glass to solve the problem of glass solution stratification in the prior art.

[0004] The technical solution of this utility model is: a high-efficiency platinum molten glass refining device, comprising a pipe, a first mixing unit and a second mixing unit arranged sequentially within the pipe, the first mixing unit comprising a plurality of left-handed blades that are rotationally symmetric about the straight line where the pipe axis is located, the left-handed blades being connected to the inner wall of the pipe; the second mixing unit comprising a plurality of right-handed blades that are rotationally symmetric about the straight line where the pipe axis is located, the right-handed blades being connected to the inner wall of the pipe.

[0005] Preferably, in the projection onto the cross-section of the pipe, both the first mixing unit and the second mixing unit are formed in an annular shape, with a cylindrical mixing cavity formed in the center.

[0006] Preferably, the first mixing unit includes two centrally symmetrical left-handed blades; the second mixing unit includes two centrally symmetrical right-handed blades.

[0007] Preferably, in the first direction, the starting end of the helix of the left-handed blade is the first end, and the ending end is the second end, and the straight line containing the first end and the straight line containing the second end are parallel to each other;

[0008] The starting end of the right-handed blade helix is ​​the third end, and the ending end is the fourth end. The straight lines containing the third end and the fourth end are parallel to each other and perpendicular to the straight lines containing the first end and the second end.

[0009] Preferably, the straight lines containing the first end, the second end, the third end, and the fourth end are all perpendicular to and intersect the straight line containing the pipe core.

[0010] Preferably, both ends of the pipe are provided with connecting flanges. Compared with the prior art, the advantages of this utility model are:

[0011] (1) In this utility model, by setting the mixing unit, the glass solution is continuously mixed multiple times when it flows, which effectively avoids the occurrence of stratification.

[0012] When the glass solution flows through the first mixing unit, it undergoes a left-handed swirling flow, and when it flows through the second mixing unit, it undergoes a right-handed swirling flow. Thereafter, the swirling direction is continuously alternating. Furthermore, when the flow direction is changed, the third end is cut and the first end is cut in sequence. This ensures that the glass solution is continuously cut and fused throughout the entire flow process, greatly improving the mixing efficiency.

[0013] By incorporating a mixing chamber, the glass solution flows into the mixing chamber while rotating, and simultaneously, the glass solution in the mixing chamber is squeezed and flows to the blades to continue rotating, thus increasing the efficiency of glass solution exchange and mixing inside the pipe.

[0019] The present invention will be further described in detail below with reference to specific embodiments:

[0020] like Figures 1-3 As shown, this invention is applied to the clarification process of molten glass solution. Pipe 1 is connected to the flow channel of the clarified glass solution via a connecting flange 11. As the glass solution flows through pipe 1, it sequentially and repeatedly flows through the first mixing unit 2 and the second mixing unit 3. Specifically, when flowing through the first mixing unit 2, it undergoes left-handed flow guided by the left-handed blade 21; when flowing through the second mixing unit 3, it undergoes right-handed flow guided by the right-handed blade 31. Simultaneously, the solution flows into the central mixing chamber 1a, where it is squeezed towards the blades, forming a continuous squeezing cycle. Furthermore, upon entering the first mixing unit 2, the first end 211 cuts the solution; upon flowing from the first mixing unit 2 to the second mixing unit 3, it is again cut and mixed by the third end 311, and this cycle continues. Through a powerless design, the solution is mixed during the glass solution flow, preventing stratification. Simultaneously, the use of subsequent stirring equipment can be eliminated, reducing production costs.

[0021] Specifically:

[0022] A high-efficiency platinum molten glass refining device includes a pipe 1, a first mixing unit 2 and a second mixing unit 3 arranged sequentially within the pipe 1. The first mixing unit 2 includes a plurality of left-handed blades 21 that are rotationally symmetric about the straight line where the axis of the pipe 1 is located, and the left-handed blades 21 are connected to the inner wall of the pipe 1. The second mixing unit 3 includes a plurality of right-handed blades 31 that are rotationally symmetric about the straight line where the axis of the pipe 1 is located, and the right-handed blades 31 are connected to the inner wall of the pipe 1.

[0023] In this embodiment, as Figure 3 As shown, on the projection onto the plane containing the cross-section of pipe 1, both the first mixing unit 2 and the second mixing unit 3 form annular shapes. The mixing chamber 1a, formed by the inner sides of the left-handed blade 21 and the right-handed blade 31, can be considered as a cylindrical, unclosed cavity. The diameter of the mixing chamber 1a can be set by the width of the left-handed blade 21 and the right-handed blade 31, i.e., the diameter of pipe 1 minus the diameter of the two first ends 211 or the two third ends 311 is the diameter of the mixing chamber 1a. The arrangement of the mixing chamber 1a allows the glass solution to flow simultaneously towards the center of pipe 1, increasing the mixing efficiency of the glass solution.

[0024] In this embodiment, the first mixing unit 2 has two left-handed blades 21 arranged in a centrally stacked configuration. The second mixing unit 3 has two right-handed blades 31 arranged in a centrally symmetrical configuration. Of course, in some embodiments, the number of left-handed blades 21 and right-handed blades 31 can be different, and the number of left-handed blades 21 and right-handed blades 31 can be the same or different in a single first mixing unit 2 and second mixing unit 3. In other embodiments, the two or more left-handed blades 21 in the first mixing unit 2 can also be non-rotationally symmetrical. Similarly, the two or more right-handed blades 31 in the second mixing unit 3 can also be non-rotationally symmetrical. All the configurations described above enable the mixing of the glass solution.

[0025] For ease of explanation, such as Figure 2 As shown, the first direction is defined by the straight line along the axis of pipe 1 and the direction of glass solution flow. In this first direction, the starting end of the helix of the left-handed blade 21 is the first end 211, and the ending end is the second end 212. The straight line containing the first end 211 is parallel to the straight line containing the second end 212. The starting end of the helix of the right-handed blade 31 is the third end 311, and the ending end is the fourth end 312. The straight line containing the third end 311 is parallel to the straight line containing the fourth end 312.

[0026] In this embodiment, the straight lines containing the first end 211, the second end 212, the third end 311, and the fourth end 312 are all perpendicular to and intersect the straight line containing the core of pipe 1. Furthermore, the straight lines containing the first end 211 and the second end 212 are perpendicular to the straight lines containing the third end 311 and the fourth end 312. This ensures that when the glass solution flows from the first mixing unit 2 into the second mixing unit 3, the third end 311 shears the glass solution; as the solution continues to flow into the next set of first mixing units 2, the first end 211 shears the solution. This continuous shearing and mixing of multiple solutions greatly improves the mixing efficiency and prevents solution stratification.

[0027] In addition, in this embodiment, the pipe 1, the connecting flange 11, the left-hand blade 21 and the right-hand blade 31 are all made of Pt or Pt group metals, which are resistant to high temperature and stable, so as to ensure the stability of solution flow.

They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
