Description

Technical Field

[0001] The invention relates to the technical field of glass substrate production, and in particular to an automatic unloading device suitable for the production of electronic display glass substrates. Background Art

[0002] In the normal production of glass substrates, as the walls of the glass kiln pool are continuously eroded by high-temperature glass liquid, a large amount of zirconium will be deposited on the bottom of the kiln pool. When glass liquid with a higher zirconium content is brought into normal glass liquid, stripes will be formed in the glass due to the difference in glass composition. The existence of stripes will seriously affect the visual effects of electronic display devices and is one of the items that need to be strictly controlled in the production of display glass.

[0003] At present, the solution to the streaks is to discharge the material through a platinum channel stirring barrel. Specifically, there is a heating device on the discharge pipe of the platinum channel stirring barrel. When the discharge pipe is heated to a certain temperature, the glass liquid will be discharged. As the glass liquid flows, a large amount of heat is brought to the discharge pipe, and the temperature around the discharge pipe will rise rapidly. Even if the heating device is turned off, the glass liquid will not stop flowing out. Therefore, according to the size of the glass liquid flow, a series of measures such as blowing compressed air and plugging are used manually to stop the unloading; however, since the glass liquid temperature at this time is above 1000℃, manual operation is very dangerous. In addition, the high-zirconium glass liquid discharged from the stirring barrel is only a part of the deposited in the platinum channel. When the glass liquid flow in the kiln changes, the high-zirconium glass liquid deposited on the bottom of the kiln pool will be drawn into the normal glass liquid to form streaks.

[0004] This type of stripes can only be effectively solved by unloading the kiln. However, the discharge hole reserved at the bottom of the kiln is mainly used for unloading before the kiln is cold repaired. During normal production, the discharge hole contains solidified cold glass. If unloading is done from the discharge hole, the cold glass must first be melted manually with a burner. In addition, the diameter of the kiln discharge hole is several times that of the outlet of the platinum channel discharge pipe, and the flow rate of the outflowing glass liquid is very large. Once unloaded, the discharge amount cannot be controlled and it is difficult to stop the unloading. The risk factor is very high, which is directly related to the life safety of the operator.

[0005] Therefore, how to achieve non-manual and controllable start and stop of the unloading process, thereby improving the safety of glass substrate production, has become a technical problem that needs to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Reference Figure 1 As shown, the present invention is an automatic unloading device suitable for the production of electronic display glass substrates, comprising a kiln pool bottom 1, a support structure 102 is arranged on the bottom surface of the kiln pool bottom 1, a discharge port 101 is opened on the kiln pool bottom 1, and the discharge port 101 penetrates the support structure 102. It should be noted that the kiln pool bottom 1, the support structure 102 and the discharge port 101 are all existing structures. The specific configuration of the device is as follows: the bottom surface of the support structure 102 is located next to the discharge port 101 and is provided with two A first steel structure 2 is provided, and a slide rail 201 is arranged between the two first steel structures 2, wherein the arrangement of the two first steel structures 2 is used to improve the stability of the slide rail 201, a slider 202 is slidably connected to the slide rail 201, a double-rod cylinder 203 is arranged on the bottom surface of the slider 202, a movable end of the double-rod cylinder 203 is fixedly connected to a bottom plate 204, one end of the bottom plate 204 close to the discharge port 101 is fixedly connected to a plug 207, and a cooling mechanism is arranged inside the bottom plate 204 and the plug 207.

[0030] Further, see Figure 1As shown, the bottom surface of the support structure 102 is located below the discharge port 101 and is provided with a second steel structure 3 on both sides thereof, and a single-rod cylinder 301 is provided on the bottom surface of the second steel structure 3. Accordingly, the second steel structure 3 is used to improve the stability of the single-rod cylinder 301, and the movable ends of the two single-rod cylinders 301 are commonly fixedly connected with a connecting plate 302, and a lifting ring block 303 is provided on the connecting plate 302 just below the discharge port 101, and a plurality of hanging parts 4 are fixedly connected to the bottom surface of the second steel structure 3, and the bottom end of the hanging part 4 is connected to a burning gun 402 through a universal joint 401.

[0031] Among them, the burner 402 is connected to the lifting ring block 303 through the pipe clamp 403, the pipe clamp 403 can rotate at a fixed point on the lifting ring block 303, the burner 402 is tilted toward the discharge port 101, the pipe clamp 403 can slide freely on the burner 402, and the end of the burner 402 close to the discharge port 101 is bent upward.

[0032] It should be noted that the connecting plate 302 is arranged through the inner ring of the lifting ring block 303 , the diameter of the inner ring of the lifting ring block 303 is larger than the diameter of the discharge port 101 , and the plug 207 can pass through the lifting ring block 303 to controllably block the discharge port 101 .

[0033] Furthermore, it is necessary to add that, referring to Figure 4 As shown, the plug 207 includes a drainage column 701 and a top step platform 7, the top step platform 7 is arranged on the top of the drainage column 701, and the bottom plate 204 and the drainage column 701 are fixedly connected.

[0034] Among them, it should be supplemented that the top surface diameter of the top step platform 7 is smaller than the diameter of the discharge port 101, and the bottom surface diameter of the top step platform 7 is larger than the diameter of the discharge port 101. Through such a setting, when the top step platform 7 gradually extends into the discharge port 101, the gap between the top step platform 7 and the discharge port 101 will become smaller and smaller, thereby gradually reducing the outflow of glass liquid from the discharge port 101, until the top step platform 7 completely blocks the discharge port 101, and the outflow of glass liquid from the discharge port 101 can be closed.

[0035] Reference Figure 3As shown, in an optional embodiment, the side wall of the drainage column 701 is located just above the bottom plate 204 and is fixedly connected to a spiral baffle 6, and the outer side of the spiral baffle 6 is close to the outer side wall of the drainage column 701, so that the glass liquid falling into the bottom plate 204 can flow downward along the connection between the spiral baffle 6 and the drainage column 701. This arrangement prevents the glass liquid from overflowing from the outer side of the spiral baffle 6 and from falling directly onto the bottom plate 204. Since a cooling mechanism is provided in the bottom plate 204, if the glass liquid falls directly onto the bottom plate 204, it will not only cause the glass liquid to overflow on the surface of the bottom plate 204, which is not conducive to the collection of the glass liquid, but also cause the glass liquid to condense in the low temperature area of ​​the bottom plate 204, thereby adhering to the bottom plate 204, which is also not conducive to the collection of the glass liquid, and also makes the bottom plate 204 heavier, further affecting the stability of the slide rail 201.

[0036] Reference Figure 4 As shown, in an optional embodiment, the cooling mechanism includes a water inlet pipe 205 and a water outlet pipe 206 arranged at one end of the base plate 204 away from the drainage column 701, the water inlet pipe 205 is connected to the first water inlet pipe 702, the first water inlet pipe 702 is connected to the second water inlet pipe 705, the second water inlet pipe 705 is connected to the third water inlet pipe 706, the third water inlet pipe 706 is connected to the first water outlet pipe 707, the first water outlet pipe 707 is connected to the second water outlet pipe 704, the second water outlet pipe 704 is connected to the third water outlet pipe 703, and the third water outlet pipe 703 is connected to the water outlet pipe 206.

[0037] Among them, the large sections of the first water inlet pipe 702 and the three-section water outlet pipe 703 are arranged in the bottom plate 204, the second water inlet pipe 705 is arranged at the inner center of the drainage column 701, the three-section water inlet pipe 706 is spirally arranged inside the top step platform 7 close to its outer wall, the first water outlet pipe 707 is arranged at the inner center of the top step platform 7, and the second water outlet pipe 704 is spirally arranged inside the drainage column 701 close to its outer wall.

[0038] For the setting of cooling mechanism, refer to Figure 4As shown, the cooling liquid enters the first water inlet pipe 702 through the water inlet pipe 205, and then enters the second water inlet pipe 705. Since the second water inlet pipe 705 is placed at the inner center of the drainage column 701, the cooling liquid is less affected by the high-temperature glass liquid flowing downward from the outer wall of the drainage column 701, so that the cooling liquid entering the third water inlet pipe 706 maintains a high cooling performance. Since the third water inlet pipe 706 is spirally arranged on the top step platform 7 and close to its outer wall, it can not only increase the path of the cooling liquid flowing through the outer wall of the top step platform 7, but also better reduce the top step platform 7, and the first water outlet pipe 707 is arranged at the inner center of the top step platform 7, so that the high-temperature liquid flowing out of the three-stage water inlet pipe 706 affects the cooling liquid in the three-stage water inlet pipe 706 to a lower extent. Finally, since the second water outlet pipe 704 is spirally arranged inside the drainage column 701 close to its outer wall, the temperature of the outer wall of the drainage column 701 is increased, so that the glass liquid flowing on the outer wall of the drainage column 701 always maintains smooth flow, avoiding condensation caused by low temperature, and the high-temperature liquid finally passes through the three-stage water outlet pipe 703 and flows out from the water outlet pipe 206.

[0039] Reference Figure 2 As shown, in an optional embodiment, a ball recess 5 matching the burner 402 is provided at the edge of the top surface of the lifting ring block 303, an inner rotating ball 502 is movably connected inside the ball recess 5, the inner rotating ball 502 is fixedly connected to an outer ring 501, and the pipe clamp 403 includes the outer ring 501 and the inner rotating ball 502.

[0040] The outer sleeve ring 501 is sleeved on the outer side wall of the burner 402 . The hanger 4 , the burner 402 and the ball recesses 5 are all provided with four. The four ball recesses 5 are arranged at equal intervals on the lifting ring block 303 .

[0041] When using the device for unloading, the combustible gas is input into the burner 402, and ignited at the port of the burner 402 facing the discharge port 101, and then the flame is adjusted. The steps are as follows: start the two single-rod cylinders 301 at the same time to control the lifting of the connecting plate 302 and the lifting ring block 303. At this time, the outer ring 501 slides on the burner 402, and the inner rotating ball 502 rotates in the ball recess 5, so as to adjust the angle of the burner 402 to ensure that the flames of the four burner 402 ports can be vertically upward after the interaction. If necessary, the amount of the input combustible gas of a burner 402 can be adjusted separately until the flames of the four burner 402 are vertically upward after the interaction. The flame can be directed vertically upward, thereby maintaining the best effect of melting the cold glass condensed in the discharge port 101. It should be noted that the minimum spacing between the burners 402 needs to be larger than the diameter of the discharge port 101 to prevent the glass liquid from dripping on the burner 402 when it is unloaded. When the glass liquid flows out of the discharge port 101, the input of combustible gas into the burner 402 is stopped, and the flame of the burner 402 will be extinguished. At this time, the height of the connecting plate 302 and the lifting ring block 303 is raised by the single-rod cylinder 301, so that each burner 402 is as far away from the glass liquid flowing out of the discharge port 101 as possible, thereby protecting the burner 402 from contamination.

[0042] When the heating device of the platinum channel stirring barrel fails, the outlet end of the discharge pipe of the platinum channel stirring barrel can be heated by setting a burner 402, a lifting ring block 303, etc. according to the above operation steps, thereby facilitating the outflow of the glass liquid.

[0043] It should be noted that the above control process can be uniformly controlled through an existing industrial computer or a movable small control cabinet, including but not limited to controlling the input of combustible gas, controlling the opening and closing of the single-rod cylinder 301, controlling the opening and closing of the double-rod cylinder 203, controlling the input of cooling liquid, etc.

[0044] When the rate at which the glass liquid flows out of the discharge port 101 is too high, but the total discharge volume does not reach the expected level, the slider 202 can be moved to place the plug 207 directly below the discharge port 101, and cooling liquid is input into the water inlet pipe 205. The double-rod cylinder 203 is started to gradually move the top step platform 7 into the discharge port 101. Since the temperature of the outer wall of the top step platform 7 is reduced due to the input of cooling liquid, and the gap between the outer wall of the top step platform 7 and the inner wall of the discharge port 101 can be controlled to decrease, the rate at which the glass liquid flows out of the discharge port 101 is reduced. rate until it reaches the expected position. If adjusting the rising distance of the top ladder platform 7 alone cannot make the glass liquid flow out of the discharge port 101 reach the expected rate, at this time, compressed cold air can be introduced into the burner 402, and then the angle of the burner 402 can be adjusted to ensure that the compressed cold air can be blown at the root of the glass liquid, so as to control the outflow rate of the glass liquid in an auxiliary cooling manner until it reaches the expected position. If the compressed cold air introduced into the burner 402 cannot achieve the expected auxiliary cooling effect, the compressed cold air can be switched to cooling liquid.

[0045] When the total discharge volume reaches the expected amount, it is only necessary to adjust the height of the plug 207 through the double-rod cylinder 203 to completely block the discharge port 101 first. In addition, in addition to the cooling liquid continuously entering the three-stage water inlet pipe 706 through the water inlet pipe 205, thereby taking away the heat of the glass liquid at the junction of the top step platform 7 and the discharge port 101 and promoting its condensation, it is also possible to introduce compressed cold air into the burner 402, according to the above steps, to reduce the heat at the junction of the top step platform 7 and the discharge port 101, and further increase the speed of blocking the discharge port 101 until the glass liquid no longer flows out of the discharge port 101.

[0046] By setting the single-rod cylinder 301, the burning gun 402 and the pipe clamp 403, the controllable adjustment angle of the burning gun 402 is utilized, which not only makes the unloading of the discharge port 101 unnecessary for manual operation, but also quickly melts the cold glass condensed in the discharge port 101 for unloading. By setting the double-rod cylinder 203, the plug 207 and the cooling mechanism, the rate of glass liquid flowing out of the discharge port 101 is successfully controlled quickly and efficiently, and the utilization rate of the cooling liquid is greatly improved, which is conducive to the glass liquid flowing down along the outer wall of the drainage column 701 and being collected. The setting of the spiral baffle 6 avoids the contamination of the bottom plate 204, which is further conducive to the collection of the glass liquid. The device as a whole realizes the non-manual and controllable start and termination of the unloading process, and the structure is exquisitely arranged, which greatly improves the safety of the unloading process.

[0047] In an optional embodiment, the slider 202 can be controlled to slide left and right on the slide rail 201, that is, the end of the slide rail 201 can be fixedly connected to a cylinder, and the movable end of the cylinder is fixedly connected to the slider 202, so that the left and right sliding of the slider 202 is automated, further improving the automation level of the device.

[0048] In an optional embodiment, the burner 402 is made of a high temperature resistant metal tube, such as a titanium alloy metal tube, and such a configuration makes the burner 402 more durable.

[0049] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
