Description

Technical Field

[0001] The utility model relates to the technical field of glass processing and manufacturing, in particular to an anti-overflow and defoaming structure. Background Art

[0002] The process of manufacturing glass usually includes a melting process of melting glass raw materials to obtain molten glass, a clarification process of removing bubbles in the molten glass to clarify the molten glass, and a forming process of forming the clarified molten glass into a predetermined shape. Glass melting equipment is one of the key equipment for producing optical glass. Optical glass has more stringent requirements on the clarification process of molten glass than ordinary glass. The existing optical glass melting equipment has a single heating method and uneven heating of the molten glass, which makes the glass raw materials more volatile and has a low utilization rate. The degassing process of the glass solution is slow, and it is difficult to completely discharge all the tiny bubbles, which makes the bubble clarification and homogenization incomplete during the glass melting process, and the melting efficiency is low.

[0003] For example, in the production of glass for chemical tempering and ion exchange, after the raw materials are melted in the melting pool, the molten raw materials are sent to the heating pool for clarification and elimination of bubbles. However, when there are many bubbles in the raw materials and a large amount of raw materials entering the heating pool, the heating pool is prone to foaming, causing the raw material solution to overflow from the heating pool. The overflowing glass seriously corrodes the surrounding pad bricks and copper sleeves, requiring more manpower and material resources for maintenance and repair, causing equipment damage and affecting production continuity.

[0004] Therefore, a process for preparing optical glass with a high refractive index proposed in the patent with publication number CN113480143A adds a side-blowing defoaming stirring rod during stirring and melting to assist in removing bubbles from the optical glass melt, reduce the presence of tiny bubbles, and effectively improve the preparation quality of the optical glass. Side-blowing defoaming can indeed effectively eliminate most bubbles, but for open containers, side blowing can easily blow the raw material solution out of the container, and the raw material solution may splash due to the unstable side blowing airflow. Compared with overflow, the damage range is wider and more unstable, and it is more likely to cause personal injury. Utility Model Content

[0005] The utility model aims to provide an anti-overflow defoaming structure to solve the technical problem that the existing side-blowing defoaming is prone to equipment damage and personnel injury due to unstable airflow.

[0006] The embodiments of the present invention are implemented by the following technical solutions:

[0007] The invention discloses an overflow prevention and defoaming structure, comprising a side blowing pipe for side blowing bubbles of a solution in a clarifying container and a baffle plate arranged outside the clarifying container for blocking the solution blown out by the side blowing pipe, and also comprising a receiving tank for receiving overflow liquid when the clarifying container overflows.

[0008] Preferably, the baffle is arranged at the top of the receiving tank, and the clarification container is provided with a plurality of overflow holes for controlling the liquid level and recovering overflow liquid and splashing liquid.

[0009] Preferably, the side blowing pipe is provided with a side blowing port for side blowing and defoaming the falling solution and a lower blowing port for side blowing and defoaming the overflowing solution and driving the overflowing liquid back to the clarification container through the overflow hole.

[0010] Preferably, the clarification container is further provided with a plurality of drainage columns at the drop port for drainage to prevent splashing and bubble generation due to falling.

[0011] Preferably, it also includes a smelting pool for conveying solution to the clarification container and a conveying pipe arranged above the drainage column.

[0012] Preferably, the receiving groove is configured to be in an arc shape to facilitate the overflow liquid to flow back to the overflow hole.

[0013] Preferably, the receiving tank is further provided with a heightening plate for heightening the receiving tank to prevent overflow liquid from flowing out of the receiving tank.

[0014] By adopting the technical scheme, when the side blowing pipe detects and defoams the bubbles in the solution, the solution splashed by the side blowing can be blocked by the baffle to prevent it from splashing out of the clarification container and causing equipment damage or personal injury; and after the baffle blocks the splashing liquid, a part of it flows back to the clarification container on the spot, and the other part falls into the receiving tank and flows back to the clarification container through the overflow hole along the curvature of the receiving tank, thereby reducing the waste of materials and ensuring production safety. The molten material falls onto the inner wall of the clarification container through the drainage column, thereby reducing the generation of bubbles when falling to the liquid surface. When there is too much overflow and the overflow hole below does not have time to overflow, when the solution overflows from the upper part of the clarification container, the side blowing port cannot blow the overflowed solution, and the overflowed solution is blown down and defoamed through the lower blowing port, and the solution in the receiving tank can be fully blown back to the clarification container to prevent residue.

[0015] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0016] 1. The utility model blocks the splashing solution of the side blowing by the baffle plate to prevent it from splashing out of the clarification container and causing damage to the equipment or injury to personnel;

[0017] 2. After the splashing liquid is blocked by the utility model, it flows back to the clarification container through the overflow hole, thus reducing the waste of materials;

[0018] 3. The utility model blows down the overflowed solution through the downward blowing port to eliminate bubbles, and can fully blow the solution in the receiving tank back to the clarification container to prevent residue. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1

[0029] An anti-overflow defoaming structure includes a side blowing pipe 3 for side blowing bubbles of a solution in a clarifying container 1 and a baffle 41 arranged outside the clarifying container 1 for blocking the side blowing pipe 3 from blowing out a solution, and also includes a receiving tank 4 for receiving overflow liquid when the clarifying container 1 overflows.

[0030] In this embodiment, a smelting pool 2 for conveying solution to the clarification container 1 and a conveying pipe 21 disposed above the drainage column 11 are also included.

[0031] In this embodiment, the receiving groove 4 is configured to be in an arc shape to facilitate the overflow liquid to flow back to the overflow hole 12 .

[0032] In this embodiment, the receiving tank 4 is further provided with a heightening plate 42 for heightening the receiving tank 4 to prevent the overflow liquid from flowing out of the receiving tank 4 .

[0033] Working principle and usage:

[0034] During operation, when the side blowing pipe 3 detects and defoams the bubbles in the solution, the baffle 41 can be used to block the solution splashed by the side blowing, so as to prevent it from splashing out of the clarification container 1 and causing equipment damage or personal injury; and after the baffle 41 blocks the splashing liquid, a part of it flows back to the clarification container 1 on the spot, and the other part falls into the receiving tank 4, and flows back to the clarification container 1 through the overflow hole 12 along the curvature of the receiving tank 4, thereby reducing the waste of materials and ensuring production safety. Moreover, the molten material falls onto the inner wall of the clarification container 1 through the drainage column 11, thereby reducing the bubbles generated when falling to the liquid surface. When the overflow is too much and the overflow hole 12 below does not have time to overflow, when the solution overflows from the upper part of the clarification container 1, the side blowing port 32 cannot blow the overflowing solution, and the overflowing solution is defoamed by blowing downwards through the lower blowing port 31, and the solution in the receiving tank 4 can be fully blown back to the clarification container 1 to prevent residue.
