Description

Technical Field

[0001] The utility model relates to the field of glass production, and specifically relates to a glass liquid clarification device. Background Art

[0002] Bubbles are visible gas inclusions in glass, which not only affect the appearance quality of products, but more importantly, affect the transparency and mechanical strength of glass. The size of bubbles in glass ranges from a few tenths of a millimeter to several millimeters.

[0003] The existence of bubbles seriously affects the mechanical strength, transparency, etc. of glass. Currently, common methods for removing bubbles in glass are mostly adding clarifying agents to the glass liquid and then removing bubbles through a slow stirring device in the glass flow channel. These methods not only have low efficiency, but also it is difficult to remove tiny bubbles during use, making the entire glass flow channel structure complex and the equipment cost high. Content of the Utility Model

[0004] This application aims to address the deficiencies in the prior art and provide a glass liquid clarification device.

[0005] This application provides the following technical solutions:

[0006] A glass liquid clarification device, characterized in that: it includes a box body, an inlet pipe is provided on the box body, a filtrate orifice plate is provided in the box body below the liquid outlet of the inlet pipe, a group of first electric heating elements are provided on the filtrate orifice plate, an exhaust port is provided at the top of the box body, and a drain pipe is provided at the bottom of the box body.

[0007] Based on the above technical solutions, the following further technical solutions may be available:

[0008] The filtrate orifice plate is made of platinum, and the holes on it are round holes with a mesh number of ≥100 meshes.

[0009] The box body is cylindrical, the diameter of the bottom of the box body is d, the height is H1, the distance between the filtrate orifice plate and the bottom is H2, and the volume of the glass liquid is V, so as to ensure .

[0010] A support platform corresponding to the filtrate orifice plate is provided on the inner wall of the box body.

[0011] The center point of the filtrate orifice plate sinks slightly, making the whole filtrate orifice plate conical, and its taper is less than or equal to 3 degrees.

[0012] A group of second electric heating elements are provided on the inner wall of the box body, and the second electric heating elements are distributed.

[0013] Two groups of second electric heating elements are provided on the inner wall of the box body, and the two groups of second electric heating elements are respectively distributed on the inner walls of the box body on the upper and lower sides of the filtrate orifice plate.

[0014] Advantages of the utility model:

[0015] The utility model has a simple structure and is convenient to use. By allowing the glass liquid to flow into the box body and flow towards the platinum original sheet with round holes in the middle of the box body, and utilizing the gravity, the visible bubbles in the glass liquid are left above the platinum round sheet, achieving the clarification effect. Finally, the glass liquid after filtering the bubbles flows out of the box body, avoiding the use of clarifying agents and simplifying the glass production equipment. Description of the drawings
