Description
Technical Field

[0002] Coated glass is a glass surface coated with one or more layers of metal, alloy or metal compound film to change the optical properties of the glass. Chemical vapor deposition is a main process for producing coated glass by online coating, and its process includes physical process and chemical reaction process. Its principle is to spray organic metal compound or inorganic compound vapor onto the high-temperature glass plate passing under the coater during the forming process, so that it decomposes, oxidizes and reacts on the surface of the glass plate to form an attached film of metal oxide or inorganic matter, and a hard film layer is formed on its surface after the glass is cooled. This process has high requirements for the working conditions of the tin bath. If the floating particles in the tin bath space, such as stannous oxide and stannous sulfide, fall on the glass plate, it will cause the glass to have optical distortion points. The film layer at the optical distortion point is not firmly attached, and it is easy for the film layer to fall off, resulting in pinhole defects. Therefore, the need to improve the working conditions in the tin bath has become a problem that needs to be solved in the production of coated glass. Utility Model Content

[0033] The air blowing pipe 3 penetrates into the tee piece 1 , and the pipe opening of the air blowing pipe 3 is arranged upward and extends into the air outlet pipe section 121 . The air blowing pipe 3 is connected to a high-pressure air source, and a valve 31 is arranged on the air blowing pipe 3 .
[0034] The working principle of this device is as follows:
[0035] The junction of the contraction section 92 and the narrow section 93 of the tin bath is the upstream position of the coater, so a tin bath exhaust device is set at this position. The air pressure in the tin bath is higher than the outside atmospheric pressure, so passive exhaust can be used for exhaust. The movable cover is in the open state to open the upper port of the extension pipe section, and the tin bath is connected to the outside atmosphere through the air inlet pipe section, the air outlet pipe section, and the extension pipe section. Under the action of the pressure difference, the gas in the tin bath will be passively discharged to the outside, and the floating particles will be discharged together during the gas discharge process. Since the floating particles in the tin bath space are reduced, the light distortion points on the glass plate are greatly reduced, thereby solving the coating pinhole defect.
[0036] The adjustment of the movable cover plate 5 can change the opening size of the upper port 22 of the extension pipe section 2 and thus adjust the exhaust volume. The present application provides two embodiments. Embodiment 1 is a manual opening and closing structure. The operator uses the hook 71 of the hand crank 7 to hang the hanging ring 611, and rotates the hand crank 7 to drive the input shaft end 61 to rotate, and then drives the output shaft end 62 to rotate to drive the movable cover plate 5 to rotate to adjust the opening size of the upper port 22. Embodiment 2 is an electric opening and closing structure. The driving motor 8 drives the input shaft end 61 to rotate, and then drives the output shaft end 62 to rotate to drive the movable cover plate 5 to rotate to adjust the opening size of the upper port 22.
[0037] The device also has an active exhaust function, which allows high-pressure gas to be introduced into the gas outlet pipe section 12 through the air blowing pipe 3, and the gas is blown out upward, thereby improving the exhaust efficiency of suspended particulate matter.
[0038] The suspended particles in the exhaust gas that are not discharged from the upper port 22 will reach the slag discharge pipe section 13 after natural sedimentation and be temporarily stored in the slag storage space. After a period of time, the slag can be discharged by opening the closed door. The closed door 4 adopts an upper rotating shaft 44 design and the door frame is arranged in an inclined manner. Therefore, when the knob is turned, the door panel will naturally droop to a vertical state and remain open, which is convenient for slag discharge and slag cleaning. The door panel 42 is pushed up by the handle 45, and the locking action can be completed by tightening the knob 43. The structure is simple, reliable and easy to operate.
[0039] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
