Description

Technical Field

[0001] The invention relates to the technical field of glass forming, and more particularly to a float process production equipment for glass production. Background Art

[0002] Float glass production equipment is one of the commonly used production and molding devices for tempered glass production raw materials. Among them, common float glass production equipment is mainly composed of raw material processing system, melting furnace, tin bath, annealing furnace, detection and control system and other mechanisms. The specific process of glass production by float glass production equipment is as follows: 1. Raw material processing: quartz sand, soda ash, limestone and other raw materials are weighed and mixed in proportion; 2. Melting: The raw materials are melted at high temperature in the melting furnace to form uniform glass liquid; 3. Molding: The glass liquid flows from the melting furnace into the tin bath, flattens on the surface of the tin liquid and cools to form; 4. Annealing: The formed glass ribbon enters the annealing furnace and is slowly cooled to eliminate internal stress; 5. Cutting and stacking: The annealed glass ribbon is cut into the required size by the cutting equipment; 6. Detection: The detection system is used to detect the produced glass;

[0003] In the actual operation process, we found that some glass surfaces had tin spots, tin drops and other pollution phenomena. In the later investigation, we found that the main reason for this phenomenon was that the protective gas delivery pipe of the tin tank was blocked. The main reason for this phenomenon was the accumulation of tin slag or impurities: the tin liquid in the tank may be oxidized to generate tin slag, which may flow into the output pipe with the protective gas and gradually accumulate to cause blockage. When the above situation occurs, it can only be discovered through manual maintenance of the corresponding equipment, which causes a certain waste of manpower;

[0004] Therefore, we are in urgent need of a float process production equipment for glass production to solve this problem. Summary of the invention

A slide rail is arranged inside the hollow plate 410, and a first roller slider 4051 is movably sleeved on the outer surface of the slide rail, and a first rubber plate 4052 is installed on the side of the first roller slider 4051 close to the hollow annular plate 411, and the inner surface of the first rubber plate 4052 is matched with the outer surface of the slide rail, and first telescopic plates 412 are installed on both sides of the top of the first roller slider 4051, and the first telescopic plates 412 are attached to the inner wall of one side of the hollow plate 410, and When the first telescopic plate 412 and the first roller slider 4051 are attached to the inner wall of one side of the hollow plate 410, an independent sealed space can be formed between the three, and the compressed protective gas inside the hollow annular plate 411 can be transmitted to the inside of the hollow plate 410 and contact the first rubber plate 4052. As the air pressure inside the hollow plate 410 increases, the first rubber plate 4052 and the first roller slider 4051 are driven to move away from the hollow annular plate 411, thereby driving the overall length of the telescopic pipe 404 to stretch, and the outer wall of the first roller slider 4051 away from the hollow plate 410 is installed on the inner side of the first annular plate 405;

[0051] The inner wall of the output pipe 403 is sequentially provided with a first air groove and a second air groove along its axial extension, the first air groove and the second air groove are independent of each other and not connected to each other, and the opening positions of the two are opposite, an auxiliary slide rail is installed on the inner wall of the first air groove, and the outer wall of the auxiliary slide rail is sleeved with a second roller slider 502, a side of the second roller slider 502 close to the position of the U-shaped tube 4081 is installed with a U-shaped rubber plate 501, and a second telescopic plate is installed on the side of the U-shaped rubber plate 501 close to the position of the U-shaped tube 4081, an independent sealed space can be formed between the side of the second telescopic plate, the side of the U-shaped rubber plate 501 and the inner wall of the first air groove, a scraping annular plate 5 is installed on the outer wall of the second roller slider 502 away from the first air groove, the scraping annular plate 5 is attached to the inner side surface of the output pipe 403, and is used to scrape impurities attached to the inner side surface of the output pipe 403, the U-shaped tube 4081 has two sets of air outlet branches, and the two sets of air outlet branches are respectively arranged in the first air groove and the second air groove.

[0052] In the embodiment of the present application, another set of gas input ends of the gas compression device 406 is installed with an impurity storage tank for recovering the impurities cleaned inside the output pipe 403, and solenoid valves are installed inside the two sets of gas input ends of the gas compression device 406, inside the three-hole tube 407, inside the two sets of auxiliary Y-shaped tubes 408, and inside the U-shaped tube 4081 for controlling the flow direction of the gas.

[0053] The specific working process of the embodiment of this part of the application is as follows: when the control system determines that there is a pipeline leakage in the output pipe 403, the gas compression device 406 inputs a stable working current, and compresses part of the protective gas inside the protective gas delivery device 4 through another group of output ends of the protective gas delivery device 4 and a group of gas input ends of the gas compression device 406, and delivers it to the inside of the hollow annular plate 411 through a group of auxiliary gas outlet ends of the auxiliary Y-shaped tube 408. The compressed air inside the hollow annular plate 411 is transmitted to the inside of the hollow plate 410. As the air pressure inside the hollow plate 410 rises, the first rubber plate 4052 is driven to move to a position away from the hollow annular plate 411, and the first rubber plate 405 2 drives the first roller slider 4051, the first annular plate 405 and the telescopic pipe 404 to move accordingly.

[0054] When the control system determines that a blockage occurs inside the output pipe 403, the gas compression device 406 inputs a stable working current, and compresses part of the protective gas inside the protective gas delivery device 4 through another group of output ends of the protective gas delivery device 4 and a group of gas input ends of the gas compression device 406, and inputs the compressed gas into the first gas groove of the output pipe 403 through another group of auxiliary gas outlet ends of the auxiliary Y-tube 408 and a group of gas outlet branches of the U-tube 4081, thereby driving the U-shaped rubber plate 501, the second roller slider 502 and the scraping annular plate 5 to move away from the protective gas delivery device 4. During the movement of the scraping annular plate 5, the impurities attached to the inner side of the output pipe 403 are automatically cleaned, thereby ensuring that the output pipe 403 can normally deliver the protective gas, and further ensuring the overall quality of the glass ribbon.

[0055] Reference Figure 1 as well as Figures 7 and 8 As shown, the present invention provides a float glass production equipment for glass production, wherein a filter plate 504 is installed on the inner wall of one end of the output pipe 403 away from the protective gas delivery device 4 for filtering impurities in the protective gas, and a countersunk groove is provided on the inner side surface of the output pipe 403 near the second gas groove, a sealing plate 503 adapted thereto is movably installed in the countersunk groove, and a torsion spring is installed on the side of the sealing plate 503 for limiting the position of the sealing plate 503 in the countersunk groove.

The adsorption force generated by the gas compression device 406 drives the sealing plate 503 to rotate counterclockwise by ninety degrees.

The compressed air inside the hollow annular plate 411 is transmitted to the inside of the hollow plate 410. As the air pressure inside the hollow plate 410 rises, the first rubber plate 4052 is driven to move to a position away from the hollow annular plate 411. The first rubber plate 4052 drives the first roller slider 4051, the first annular plate 405 and the telescopic pipe 404 to move accordingly.

In this state, the telescopic pipe 404 completely wraps the outer wall of the corresponding output pipe 403;

[0060] Cleaning impurities inside the pipeline: When the control system determines that there is a blockage inside the output pipe 403, the gas compression device 406 inputs a stable working current, and compresses part of the protective gas inside the protective gas delivery device 4 through another group of output ends of the protective gas delivery device 4 and a group of gas input ends of the gas compression device 406, and inputs it into the first gas groove of the output pipe 403 through another group of auxiliary gas outlet ends of the auxiliary Y-tube 408 and a group of gas outlet branches of the U-tube 4081, thereby driving the U-shaped rubber plate 501, the second roller slider 502 and the scraping annular plate 5 to move away from the protective gas delivery device 4. During the movement of the scraping annular plate 5, the impurities attached to the inner side of the output pipe 403 are automatically cleaned, thereby ensuring that the output pipe 403 can normally transport the protective gas, and further ensuring the overall quality of the glass ribbon;

The adsorption force generated by the gas compression device 406 drives the sealing plate 503 to rotate counterclockwise by ninety degrees. The adsorption force in the second air groove is transmitted to the outer side of the filter plate 504 through the countersunk groove on the inner wall of the output pipe 403, and the impurities remaining on the outer side of the filter plate 504 are recovered, thereby achieving the effect of automatically recovering the impurities cleaned inside the output pipe 403.
