Description

Technical Field

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

[0002] The float production device is one of the commonly used production and forming devices for the raw materials of tempered glass. The common float glass production device mainly consists of institutions such as a raw material processing system, a melting furnace, a tin bath, an annealing furnace, a detection and control system, etc. The specific process of glass production by the float production device is as follows: First, raw material processing: raw materials such as quartz sand, soda ash, and limestone are weighed and mixed in proportion; Second, melting: the raw materials are melted at high temperature in the melting furnace to form a uniform glass liquid; Third, forming: the glass liquid flows from the melting furnace into the tin bath, flattens on the surface of the tin liquid and cools to form; Fourth, annealing: the formed glass ribbon enters the annealing furnace and is slowly cooled to eliminate internal stress; Fifth, cutting and stacking: the annealed glass ribbon is cut into the required size by a cutting device; Sixth, detection: the produced glass is detected by a detection system;

[0003] During the actual operation process, we found that there are corresponding pollution phenomena such as tin spots and tin drops on the surface of some glass. During the later investigation, we found that the main reason for this phenomenon is that the protective gas delivery pipe of the tin bath is blocked. The main reason for this phenomenon is the accumulation of tin slag or impurities: the tin liquid in the bath may be oxidized to form tin slag, and these tin slags may flow into the output pipeline with the protective gas and gradually accumulate to cause blockage. When the above situation occurs, it can only be discovered by manually maintaining the corresponding equipment, so it causes a certain waste of manpower;

[0004] Therefore, now we urgently need a float production device for glass production to solve this problem. Summary of the Invention

One end of the output pipe away from the protective gas conveying device is installed on the inner wall of the top of the tin bath. A gas flowmeter is installed inside this set of output ends for monitoring the volumetric flow rate of the protective gas and transmitting it to the control system to determine whether there is a blockage or leakage inside the output pipe.

[0013] The control system further includes a comparison and analysis module and an alarm module;

[0014] The comparison and analysis module: is used to compare the real-time volumetric flow rate with the threshold range. If the real-time volumetric flow rate is greater than the threshold range, it is determined that there is a leakage outside the output pipe. If the real-time volumetric flow rate is less than the threshold range, it is determined that there is a blockage inside the output pipe;

[0015] The alarm module: is used to send a warning message to the staff when it is determined that the protective gas inside the output pipe is in an abnormal conveying situation.

[0016] Preferably, a protective shell is installed in the middle area of the upper surface of the protective gas conveying device. A gas compression device is provided at the other set of output ends of the protective gas conveying device. The gas compression device includes a set of gas output ends and two sets of gas input ends.

The output end of the gas compression device is installed with a three-hole pipe. The three-hole pipe has two sets of air outlets. Auxiliary Y-shaped pipes are installed inside both of these two sets of air outlets. Both of the two sets of auxiliary Y-shaped pipes are provided with two sets of auxiliary air outlets. Among them, hollow annular plates are respectively installed on the outer walls of one set of auxiliary air outlets of the two sets of auxiliary Y-shaped pipes, and U-shaped pipes are respectively installed inside the other set of auxiliary air outlets of the two sets of auxiliary Y-shaped pipes.

[0017] Preferably, the hollow annular plate is installed on the upper surface of the protective gas delivery device, and the output pipe is located inside the internal space of the hollow annular plate. An independent sealed space is provided inside the hollow annular plate. The protective gas inside the protective gas delivery device is delivered to this sealed space through a set of auxiliary air outlet ends of the auxiliary Y-shaped pipe. A telescopic pipe is installed on the upper surface of the hollow annular plate, and a first annular plate is installed on the upper surface of the telescopic pipe.

[0018] Preferably, a hollow plate is installed on the side of the output pipe away from the rubber sliding plate. One end of the hollow plate is installed inside the hollow annular plate. A slide rail is provided inside the hollow plate. A first roller slider is movably sleeved on the outer surface of the slide rail.

The compressed protective gas inside the hollow annular plate can be transmitted to the inside of the hollow plate and come into contact with the first rubber plate. As the air pressure inside the hollow plate increases, it drives the first rubber plate and the first roller slider to move away from the hollow annular plate, thereby driving the overall length of the telescopic pipe to stretch. The outer wall of the first roller slider away from the hollow plate is installed on the inner side surface of the first annular plate.

[0020] Preferably, a first air groove and a second air groove are successively provided along the axial extension of the inner wall of the output pipe.

An independent sealed space can be formed among the side surface of the second telescopic plate, the side surface of the U-shaped rubber plate, and the inner wall of the first air groove. The outer wall of the second roller slider away from the first air groove is installed with a scraping annular plate, and the scraping annular plate is attached to the inner side surface of the output pipe for scraping the impurities adhered to the inner side surface of the output pipe.

[0022] The technical effects and advantages of the present invention:

[0023] 1. When the control system determines that the inside of the output pipe is blocked, the gas compression device inputs a stable working current. Part of the protective gas inside the protective gas delivery device is compressed through the other output end of the protective gas delivery device and one gas input end of the gas compression device, and is input into the first gas groove of the output pipe through the other auxiliary air outlet end of the auxiliary Y-shaped pipe and one air outlet branch end of the U-shaped pipe. Thereby driving the U-shaped rubber plate, the second roller slider and the scraping annular plate to move away from the protective gas delivery device. During the movement of the scraping annular plate, the impurities adhering to the inner side of the output pipe are automatically cleaned, so as to ensure that the output pipe can normally transport the protective gas and further guarantee the overall quality of the glass ribbon.

[0024] 2. The adsorption force generated by the gas compression device is input into the second gas groove of the output pipe through the other auxiliary air outlet end of the auxiliary Y-shaped pipe and the other air outlet branch end of the U-shaped pipe.

Detailed implementation manners

[0034] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of the respective structures described in the following embodiments are merely examples, and a float production device for glass production according to the present invention is not limited to the respective structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] Referring to Figure 1 and Figure 2 shown, the present invention provides a float production device for glass production, including:

[0036] A tin bath 1 for forming float glass. One end of the tin bath 1 is provided with a feed inlet 101 for inputting production raw materials, and the other end of the tin bath 1 is provided with a discharge end 102 for outputting the glass after preliminary forming;

[0037] An edge roller 2 for stabilizing the forming of the glass ribbon and adjusting the real-time width and thickness of the glass ribbon. The edge roller 2 is installed on both sides of the tin bath 1, and the installation position of the edge roller 2 is adjacent to the feed inlet 101;

[0038] A gas recovery mechanism 3 is used for recovering the protective gas in the tin bath 1. The gas recovery mechanism 3 is installed on the side of the tin bath 1, and the installation position of the gas recovery mechanism 3 is adjacent to the discharge end 102;

[0039] A protective gas delivery device 4 is used for delivering the protective gas in the tin bath 1. The protective gas delivery device 4 is installed on the side of the middle area of the tin bath 1. A control mechanism 401 is installed in the middle area at the front end of the protective gas delivery device 4, and a control system is integrated inside the control mechanism 401 for monitoring the real-time state of the protective gas delivery inside the protective gas delivery device 4.

[0040] In the embodiment of the present application, a filtering mechanism is provided inside the gas recovery mechanism 3 for filtering the recovered protective gas. A gas transfer branch pipe can be provided between the gas recovery mechanism 3 and the protective gas delivery device 4, which is beneficial to re-delivering the gas recovered and filtered inside the gas recovery mechanism 3 to the inside of the protective gas delivery device 4, so as to achieve the effect of recycling the protective gas.

[0041] The specific working process of this part of the application embodiment is as follows:

[0042] The molten glass liquid is input into the inner cavity of the tin bath 1 through the feeding port 101. The glass liquid is input into the inside of the tin bath 1 and flattened on the surface of the tin liquid. Under the control of the edge roller 2, the thickness and width of the formed glass ribbon are adjusted in real time. During the forming process of the glass ribbon, the protective gas inside the protective gas delivery device 4 continuously delivers the protective gas into the tin bath 1 to prevent the tin liquid from oxidizing, keep the surface of the glass ribbon clean, and ensure that the glass ribbon is not contaminated during the forming process.

[0043] Refer to Figures 1 to 7 As shown, the present invention provides a float production device for glass production. Two sets of output ends are provided at the top of the protective gas delivery device 4. An output pipe 403 is installed inside one set of output ends. One end of the output pipe 403 away from the protective gas delivery device 4 is installed on the inner wall of the top of the tin bath 1. A gas flow meter is installed inside this set of output ends for monitoring the volume flow rate of the protective gas and transmitting it to the control system to judge whether there is a blockage or leakage inside the output pipe 403;

[0044] The control system includes a critical module, and the critical module is configured to simulate the simulated volume flow rate generated by the gas flow meter when the protective gas in the output pipe 403 is in a normal delivery state; and perform integration processing on the simulated volume flow rate to generate a corresponding threshold range;

[0045] The control system further includes a comparison and analysis module and an alarm module;

[0046] Comparison and analysis module: used to compare the real-time volume flow rate with the threshold range. When the real-time volume flow rate is greater than the threshold range, it is determined that there is a leakage outside the output pipe 403. When the real-time volume flow rate is less than the threshold range, it is determined that there is a blockage inside the output pipe 403;

[0047] Alarm module: used to send a warning message to the staff when it is determined that the protective gas inside the output pipe 403 is in an abnormal transportation situation;

[0048] A protective housing 402 is installed in the middle area of the upper surface of the protective gas delivery device 4. Another set of output ends of the protective gas delivery device 4 is provided with a gas compression device 406. The gas compression device 406 includes a set of gas output ends and two sets of gas input ends. Another set of output ends of the protective gas delivery device 4 is installed on a set of gas input ends of the gas compression device 406. The output end of the gas compression device 406 is installed with a three-hole pipe 407. The three-hole pipe 407 has two sets of air outlets. Inside each of the two sets of air outlets, an auxiliary Y-shaped pipe 408 is installed. Each of the two sets of auxiliary Y-shaped pipes 408 is provided with two sets of auxiliary air outlets. Among them, on the outer walls of a set of auxiliary air outlets of the two sets of auxiliary Y-shaped pipes 408, hollow annular plates 411 are respectively installed, and inside another set of auxiliary air outlets of the two sets of auxiliary Y-shaped pipes 408, U-shaped pipes 4081 are respectively installed;

[0049] The hollow annular plate 411 is installed on the upper surface of the protective gas delivery device 4, and the output pipe 403 is located inside the internal space of the hollow annular plate 411. An independent sealed space is opened inside the hollow annular plate 411. The protective gas inside the protective gas delivery device 4 is transported to this sealed space through a set of auxiliary air outlets of the auxiliary Y-shaped pipe 408. A telescopic pipe 404 is installed on the upper surface of the hollow annular plate 411, and a first annular plate 405 is installed on the upper surface of the telescopic pipe 404. The geometric centers of the hollow annular plate 411, the telescopic pipe 404, and the first annular plate 405 are all on the same straight line. A rubber sliding plate 409 is installed on the outer wall of one side of the output pipe 403, and a sliding groove adapted to the outer wall of the rubber sliding plate 409 is opened on the inner wall of the first annular plate 405 to ensure that the first annular plate 405 slides parallel on the outer surface of the output pipe 403;

[0050] On the side of the output pipe 403 away from the rubber slide plate 409, a hollow plate 410 is installed. One end of the hollow plate 410 is installed inside the hollow annular plate 411. Inside the hollow plate 410, a slide rail is provided. The outer surface of the slide rail is movably sleeved with a first roller slider 4051. On the side of the first roller slider 4051 close to the hollow annular plate 411, a first rubber plate 4052 is installed. The inner surface of the first rubber plate 4052 is adapted to the outer surface of the slide rail. On both sides of the top of the first roller slider 4051, first telescopic plates 412 are installed. The first telescopic plates 412 are attached to the inner wall on one side of the hollow plate 410. When the first telescopic plates 412 and the first roller slider 4051 are attached to the inner wall on one side of the hollow plate 410, an independent sealed space can be formed among the three. The compressed protective gas inside the hollow annular plate 411 can be transmitted into the hollow plate 410 and contact the first rubber plate 4052. As the air pressure inside the hollow plate 410 increases, it drives the first rubber plate 4052 and the first roller slider 4051 to move away from the hollow annular plate 411, thereby driving the overall length of the telescopic pipe 404 to be stretched. The outer wall of the first roller slider 4051 away from the hollow plate 410 is installed on the inner side surface of the first annular plate 405;

[0051] Along the axial direction of the inner wall of the output pipe 403, a first air groove and a second air groove are sequentially opened. The first air groove and the second air groove are independent of each other and do not communicate with each other, and their opening positions are opposite. An auxiliary slide rail is installed on the inner wall of the first air groove. The outer wall of the auxiliary slide rail is sleeved with a second roller slider 502. On the side of the second roller slider 502 close to the U-shaped pipe 4081, a U-shaped rubber plate 501 is installed. On the side of the U-shaped rubber plate 501 close to the U-shaped pipe 4081, a second telescopic plate is installed. An independent sealed space can be formed among the side surface of the second telescopic plate, the side surface of the U-shaped rubber plate 501 and the inner wall of the first air groove. The outer wall of the second roller slider 502 away from the first air groove is installed with a scraping annular plate 5. The scraping annular plate 5 is attached to the inner side surface of the output pipe 403 for scraping the impurities adhered to the inner side surface of the output pipe 403. The U-shaped pipe 4081 has two air outlet branch ends, and the two air outlet branch ends are respectively arranged in the first air groove and the second air groove.

[0052] In the embodiment of the present application, a impurity storage tank is installed at the other gas input end of the gas compression device 406 for recovering the impurities cleaned inside the output pipe 403. Electromagnetic valves are installed inside the two gas input ends of the gas compression device 406, inside the three-hole pipe 407, inside the two auxiliary Y-shaped pipes 408 and inside the U-shaped pipe 4081 for controlling the flow direction of the gas.

[0053] The specific working process of this part of the application embodiment 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. Through another output end of the protective gas delivery device 4 and a gas input end of the gas compression device 406, a part of the protective gas inside the protective gas delivery device 4 is compressed, and is transported to the inside of the hollow annular plate 411 through a set of auxiliary air outlet ends of the auxiliary Y-shaped pipe 408. The compressed air inside the hollow annular plate 411 is transported 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 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. During the movement of the telescopic pipe 404, the overall length is in a stretched state. When the first annular plate 405 moves to the upper surface position of the tin bath 1, the overall length of the telescopic pipe 404 is stretched to the critical state. In this state, the telescopic pipe 404 completely wraps the outer wall of the corresponding output pipe 403, thereby preventing the protective gas leaking inside the output pipe 403 from being transported into the production workshop, avoiding the risk that the oxygen concentration in some areas decreases due to the leakage of the on-site protective gas, which may lead to suffocation and other risks for the staff in this area, and at the same time avoiding the occurrence of open fire explosion of the on-site leaked protective gas;

[0054] 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. Through another output end of the protective gas delivery device 4 and a gas input end of the gas compression device 406, a part of the protective gas inside the protective gas delivery device 4 is compressed, and is input into the first gas groove of the output pipe 403 through another set of auxiliary air outlet ends of the auxiliary Y-shaped pipe 408 and a set of air outlet branches of the U-shaped pipe 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 adhering to the inner side surface of the output pipe 403 are automatically cleaned, thereby ensuring that the output pipe 403 can normally transport the protective gas and further guaranteeing the overall quality of the glass ribbon.

[0055] Referring to Figure 1 and Figures 7 to 8 As shown, the present invention provides a float production device for glass production. 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.

[0056] In the embodiment of the present application, the specific working process of this application embodiment is as follows: After the scraping annular plate 5 finishes cleaning the impurities inside the output pipe 403, the adsorption force generated by the gas compression device 406 is input into the second gas groove of the output pipe 403 through the other set of auxiliary air outlet ends of the auxiliary Y-shaped pipe 408 and the other set of air outlet branches of the U-shaped pipe 4081. 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 gas groove is transmitted to the outer side of the filter plate 504 through the counterbore groove on the inner wall of the output pipe 403 to recover the impurities remaining on the outer side of the filter plate 504, achieving the effect of automatic recovery of the impurities cleaned inside the output pipe 403.

[0057] The specific working process of the present application is as follows:

[0058] Glass forming: The molten glass liquid generated after melting is input into the inner cavity of the tin bath 1 through the feeding port 101. The glass liquid is input into the inside of the tin bath 1 and spreads flat on the surface of the tin liquid. Under the control of the edge roller 2, the thickness and width of the formed glass ribbon are adjusted in real time. During the forming process of the glass ribbon, the protective gas in the protective gas delivery device 4 continuously delivers the protective gas into the tin bath 1 to prevent the oxidation of the tin liquid, keep the surface of the glass ribbon clean, and ensure that the glass ribbon is not contaminated during the forming process.

[0059] Pipeline leakage protection: 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. Part of the protective gas inside the protective gas delivery device 4 is compressed through the other set of output ends of the protective gas delivery device 4 and a set of gas input ends of the gas compression device 406, and is delivered to the inside of the hollow annular plate 411 through a set of auxiliary air outlet ends of the auxiliary Y-shaped pipe 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, it drives the first rubber plate 4052 to move 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 pipeline 404 to move accordingly. During the movement of the telescopic pipeline 404, the overall length is in a stretched state. When the first annular plate 405 moves to the upper surface position of the tin bath 1, the overall length of the telescopic pipeline 404 is stretched to the critical state. In this state, the telescopic pipeline 404 completely wraps the outer wall of the corresponding output pipe 403.

[0060] Internal cleaning of 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. Part of the protective gas inside the protective gas delivery device 4 is compressed through the other set of output ends of the protective gas delivery device 4 and a set of gas input ends of the gas compression device 406, and is input into the first gas groove of the output pipe 403 through the other set of auxiliary air outlet ends of the auxiliary Y-shaped pipe 408 and a set of air outlet branches of the U-shaped pipe 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 adhering to the inner side of the output pipe 403 are automatically cleaned, so as to ensure that the output pipe 403 can normally transport the protective gas, and further ensure the overall quality of the glass belt;

[0061] After the scraping annular plate 5 finishes cleaning the impurities inside the output pipe 403, the adsorption force generated by the gas compression device 406 is input into the second gas groove of the output pipe 403 through the other set of auxiliary air outlet ends of the auxiliary Y-shaped pipe 408 and the other set of air outlet branches of the U-shaped pipe 4081. The adsorption force generated by the gas compression device 406 drives the sealing plate 503 to rotate counterclockwise by 90 degrees. The adsorption force in the second gas groove is transmitted to the outer side of the filter plate 504 through the counterbore groove on the inner wall of the output pipe 403 to recover the impurities remaining on the outer side of the filter plate 504, achieving the effect of automatic recovery of the impurities cleaned inside the output pipe 403.
