Description

Technical Field

[0001] This invention relates to the technical field of glass melting furnaces, and more particularly to a sealing device and glass production equipment. Background Technology

[0002] When processing molten glass in a glass melting furnace, spray guns are used on both sides of the furnace to heat the interior. Each spray gun has a corresponding working position on the furnace, and the guns need to be moved alternately to the working position to heat the gas and thus facilitate combustion.

[0003] In existing technologies, when one spray gun is operating, the other spray gun's operating position is connected to the external environment and the glass melting furnace. This causes some of the heat generated by the operating spray gun to be lost from the other operating position, thus affecting the glass processing quality. Furthermore, the high internal temperature of the glass melting furnace can cause the spray gun to oxidize and corrode over time, leading to deformation and affecting the heating process. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a sealing device that can reduce heat loss in glass melting furnaces and improve the operational stability of the spray gun.

[0005] The present invention also proposes a glass production apparatus having the above-mentioned sealing device.

[0006] A sealing device according to a first aspect of the present invention includes a furnace body and a sealing element.

[0007] An active channel is defined inside the furnace body, through which the furnace body forms a first opening and a second opening, which are separated. The active channel is used to accommodate a spray gun, and the first opening is used to connect to a glass melting furnace. A sealing element is movably connected to the furnace body, and the sealing element can move relative to the furnace body to switch between a first position and a second position. In the first position, the sealing element opens the second opening, and in the second position, the sealing element closes the second opening.

[0008] The sealing device according to embodiments of the present invention has at least the following beneficial effects: By providing a furnace body between the spray gun and the glass melting furnace, when the spray gun heats the interior of the glass melting furnace, the furnace body can reduce the oxidative corrosion of the spray gun caused by the internal temperature of the glass melting furnace. Simultaneously, by defining an active channel for accommodating the spray gun within the furnace body, the shape and structure of the spray gun can be stabilized and its active path ensured, thereby improving the operational stability of the spray gun. Furthermore, when the spray gun does not need to communicate with the glass melting furnace through the first opening, closing the second opening with a seal can prevent communication between the external environment and the glass melting furnace, thereby avoiding heat loss from the interior of the glass melting furnace.

[0009] According to some embodiments of the present invention, the sealing device further includes a first driving device connected to the sealing member to drive the sealing member to move relative to the furnace body, wherein: The sealing device further includes a sliding member connected to the side of the furnace body facing the sealing member and movably connected to the sealing member. The sealing member is driven by the first driving device to slide relative to the furnace body. Alternatively, the sealing device may further include a rotating component, the two ends of which are respectively connected to the furnace body and the sealing component, and the sealing component is driven by the first driving device to rotate relative to the furnace body.

[0010] According to some embodiments of the present invention, the sealing device further includes a first limiting member and a second limiting member, the first limiting member and the second limiting member being connected to the furnace body and spaced apart on the outer periphery of the second opening, wherein in the first position, the sealing member abuts against the first limiting member, and in the second position, the sealing member abuts against the second limiting member.

[0012] According to some embodiments of the present invention, the furnace body further includes an extension disposed on the first side and surrounding the first opening.

[0013] According to some embodiments of the present invention, the interior of the extension defines a receiving groove that communicates with the first opening.

[0014] According to some embodiments of the present invention, the interior of the seal defines a receiving cavity, the sealing device further includes a thermal insulation material filling the receiving cavity, and / or the sealing device further includes a heat insulation material covering the outer surface of the seal.

[0015] According to some embodiments of the present invention, the interior of the seal further defines a plurality of spaced-apart vent holes, the vent holes being separated from the receiving cavity, the receiving cavity being disposed between the furnace body and the vent holes.

[0016] According to a second aspect of the present invention, a glass production apparatus includes a glass melting furnace, a spray gun, and a sealing device as described in any of the above embodiments.

[0017] The glass melting furnace defines a melting chamber; the furnace body is connected to the glass melting furnace, and the first opening communicates with the melting chamber; the spray gun is movably connected to the furnace body, and in the first position, the spray gun is located in the movable channel, and in the second position, the spray gun is located outside the movable channel.

[0018] The glass production equipment according to embodiments of the present invention has at least the following beneficial effects: by movably arranging the spray gun in the movable channel, the spray gun can be spaced apart from the glass melting furnace during heating operations, thereby reducing the oxidative corrosion of the spray gun caused by the internal temperature of the glass melting furnace. When the spray gun stops working, it exits the movable channel through a second opening, at which time the seal closes the second opening, thereby isolating it from the external environment and the melting furnace chamber, thus preventing heat loss from the inside of the glass melting furnace.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] The sealing device according to a first aspect of the present invention and the glass production equipment according to a second aspect of the present invention will now be described with reference to the accompanying drawings.

[0029] A first aspect of the present invention provides a sealing device 100 for processing glass, see below. Figure 1 , Figure 2 and Figure 5 As shown, the sealing device 100 includes a furnace body 110 and a sealing element 120. The furnace body 110 has an internal movable channel 111. The movable channel 111 connects to a side wall of the furnace body 110, forming a first opening 1111 and a second opening 1112. The first opening 1111 and the second opening 1112 are spaced apart. Specifically, the movable channel 111 accommodates a spray gun 300. When the spray gun 300 needs to move to a corresponding working position, it enters the movable channel 111 through the second opening 1112 and moves along the path of the movable channel 111 until the nozzle 310 of the spray gun 300 is located at the first opening 1111. The first opening 1111 connects to a glass melting furnace 200, allowing the spray gun 300 to heat the interior of the glass melting furnace 200.

[0030] The seal 120 is connected to the furnace body 110 and is movably disposed on the side of the furnace body 110 where the second opening 1112 is formed. The seal 120 can move relative to the furnace body 110 to switch between a first position and a second position. See reference. Figure 2 As shown, when the seal 120 is in the first position, the seal 120 will avoid the second opening 1112, causing the second opening 1112 to be in the open state. At this time, the spray gun 300 can enter the moving channel 111 through the second opening 1112 to achieve the heating operation of the glass melting furnace 200. (See reference...) Figure 1As shown, when the seal 120 is in the second position, it blocks the second opening 1112, keeping it closed. At this time, the spray gun 300 is positioned outside the second opening 1112 to pause heating. Closing the second opening 1112 with the seal 120 prevents external gas from entering the active channel 111 through the second opening 1112 and then entering the glass melting furnace 200 through the first opening 1111, thus avoiding heat loss from the glass melting furnace 200.

[0031] In practical applications, spray guns 300 are respectively installed on opposite sides (such as the front and rear sides) of the glass melting furnace 200. The two spray guns 300 move alternately relative to the glass melting furnace 200 to achieve staggered heating. In related technologies, the glass melting furnace 200 has heating holes for the two spray guns 300. When one spray gun 300 is heating the interior of the glass melting furnace 200 through its heating hole, the heating hole of the other spray gun 300 is connected to the external environment and the interior of the glass melting furnace 200, resulting in heat loss and affecting the glass processing efficiency. Furthermore, since the spray guns 300 are connected to the glass melting furnace 200, they are subject to oxidation and corrosion under the high temperature inside the glass melting furnace 200, leading to deformation.

[0032] Compared to related technologies, the sealing device 100 of this embodiment of the invention, by setting a furnace body 110 between the spray gun 300 and the glass melting furnace 200, allows the furnace body 110 to reduce the oxidation and corrosion of the spray gun 300 caused by the internal temperature of the glass melting furnace 200 when the spray gun 300 is heating the interior of the glass melting furnace 200. Simultaneously, by defining an active channel 111 for accommodating the spray gun 300 within the furnace body 110, the shape and structure of the spray gun 300 can be stabilized, and its active path can be ensured, thereby improving the operational stability of the spray gun 300. Furthermore, when the spray gun 300 does not need to communicate with the glass melting furnace 200 through the first opening 1111, closing the second opening 1112 with the sealing member 120 can block the communication between the external environment and the glass melting furnace 200, thereby preventing heat loss from the interior of the glass melting furnace 200.

[0033] See Figures 1 to 4 As shown, the sealing device 100 also includes a first driving device 130, which is connected to the sealing member 120 and is used to drive the sealing member 120 to move relative to the furnace body 110 to open and close the second opening 1112. In one example, see [reference needed]. Figure 3As shown, the sealing device 100 includes a sliding member 140 (such as a slide rail or roller). A sliding groove is provided on the side of the sealing member 120 facing the furnace body 110. The sliding member 140 is connected to the side of the furnace body 110 facing the sealing member 120 and movably connected to the sliding groove of the sealing member 120. The sliding member 140 is disposed vertically between the sealing member 120 and the furnace body 110. In this embodiment, when the sealing member 120 is driven by the first driving device 130, the sealing member 120 slides relative to the sliding member 140 and the furnace body 110, thereby opening and closing the second opening 1112. By providing the sliding member 140, the positional displacement of the sealing member 120 during operation can be reduced, thereby improving the sealing effect.

[0034] In another embodiment, see Figure 4 As shown, the sealing device 100 includes a rotating component 150 (such as a rotating shaft or hinge). A rotating groove is provided on the side of the sealing component 120 facing the furnace body 110. One end of the rotating component 150 is connected to the furnace body 110, and the other end is rotatably connected to the rotating groove of the sealing component 120. The rotating component 150 is positioned vertically between the sealing component 120 and the furnace body 110. When the sealing component 120 is driven by the first driving device 130, the sealing component 120 rotates relative to the rotating component 150 around an axis parallel to the vertical direction, thereby opening and closing the second opening 1112. The use of the rotating component 150 allows the sealing device 100 to have a high degree of compactness and saves installation space.

[0035] Furthermore, in some embodiments, see [reference] Figures 1 to 4 As shown, the sealing device 100 also includes a first limiting member 160 and a second limiting member 170. Both the first limiting member 160 and the second limiting member 170 are connected to the side of the furnace body 110 facing the sealing member 120, and are positioned on the outer periphery of the second opening 1112 to abut against the sealing member 120. When the sealing member 120 is in the first position, it abuts against the first limiting member 160, ensuring that the sealing member 120 does not exceed its predetermined position and block the second opening 1112, thereby avoiding interference with the operation of the spray gun 300. In the second position, the sealing member 120 abuts against the second limiting member 170, ensuring that the sealing member 120 can completely close the second opening 1112, effectively blocking the connection between the external environment and the interior of the glass melting furnace 200, preventing heat loss.

[0036] Specifically, see Figures 1 to 3As shown, when the sealing member 120 is slidably connected to the furnace body 110, the first limiting member 160 and the second limiting member 170 are respectively positioned on both sides of the second opening 1112 in the left-right direction. In the left-right direction, the distance between the second limiting member 170 and the second opening 1112 is less than the distance between the first limiting member 160 and the second opening 1112. The sealing member 120 is located between the first limiting member 160 and the second limiting member 170 in the left-right direction. When the sealing member 120 slides relative to the furnace body 110, in the first position, the sealing member 120 abuts against the first limiting member 160 to open the second opening 1112. In the second position, the sealing member 120 abuts against the second limiting member 170 to close the second opening 1112.

[0037] See Figure 4 As shown, when the sealing member 120 is rotatably connected to the furnace body 110, the first limiting member 160 and the second limiting member 170 are arranged circumferentially around the second opening 1112. When the sealing member 120 rotates relative to the furnace body 110, and the sealing member 120 abuts against the first limiting member 160, the sealing member 120 is spaced apart from the second opening 1112 to avoid obstructing the second opening 1112. When the sealing member 120 abuts against the second limiting member 170, the sealing member 120 obstructs the second opening 1112 to close the second opening 1112.

[0038] In some embodiments, see Figure 1 and Figure 2 As shown, the furnace body 110 has an adjacent first side 112 (right side) and a second side 113 (lower side). A first opening 1111 is located on the first side 112 of the furnace body 110 and is used to connect to the glass melting furnace 200. A second opening 1112 is located on the second side 113 of the furnace body 110, and a sealing element 120 is movably connected to the second side 113 to control the opening and closing of the second opening 1112. By arranging the first opening 1111 and the second opening 1112 on adjacent sides and movably connecting the sealing element 120 to the second side 113, the operator can minimize interference with the operation of the spray gun 300 when operating the sealing element 120, such as during maintenance. Simultaneously, the first opening 1111 is used to connect to the glass melting furnace 200, while the second opening 1112 is used for operating the sealing element 120. Separating the first opening 1111 and the second opening 1112 allows for independent control of their respective functions without mutual interference.

[0039] Specifically, the first side 112 is the side of the furnace body 110 facing the glass melting furnace 200. By setting the first opening 1111 and the second opening 1112 on the first side 112 and the second side 113 respectively, the first opening 1111 and the second opening 1112 can be spaced apart in both the left-right and up-down directions, thus making the movable channel 111 inclined as a whole. When the spray gun 300 is housed in the movable channel 111, the spray gun 300 is also placed at an inclination. Along the setting direction of the movable channel 111 (the direction from the first opening 1111 to the second opening 1112), the left-right distance between the movable channel 111 and the glass melting furnace 200 gradually increases, that is, the thickness of the furnace body 110 between the spray gun 300 and the glass melting furnace 200 gradually increases, thereby further reducing the oxidation and erosion of the spray gun 300 by the internal temperature of the glass melting furnace 200.

[0040] In some embodiments, see Figures 2 to 4 As shown, the furnace body 110 also includes an extension 114, which is located on the first side 112 of the furnace body 110 and is circumferentially arranged around the first opening 1111. Specifically, when the sealing device 100 is in use, the extension 114 is connected to the side of the furnace body 110 facing the glass melting furnace 200. When the spray gun 300 is housed in the movable channel 111 so that the nozzle 310 is positioned at the first opening 1111 to heat the glass melting furnace 200, the extension 114 is circumferentially arranged around the nozzle 310, thereby extending the distance between the nozzle 310 and the interior of the glass melting furnace 200, thus reducing the erosion of the nozzle 310 by the internal temperature of the glass melting furnace 200. Furthermore, by circumferentially arranging the extension 114 around the first opening 1111, debris that falls off the nozzle 310 after being eroded can be contained in the extension 114 and will not enter the interior of the glass melting furnace 200 to contaminate the molten glass, thereby improving the quality of the glass.

[0041] Further, see Figures 2 to 4As shown, the extension 114 also defines a receiving groove 1141, which communicates with the first opening 1111. Specifically, when the spray gun 300 is placed in the movable channel 111 and the nozzle 310 is aligned with the first opening 1111 for heating operations in the glass melting furnace 200, the extension 114 not only extends the distance between the nozzle 310 and the interior of the glass melting furnace 200, reducing the erosion rate of the nozzle 310 by the high temperature of the glass melting furnace 200, but also provides additional space through its internal receiving groove 1141 to collect debris falling from the nozzle 310. The receiving groove 1141 not only allows the debris from the spray gun 300 to be effectively collected, preventing the possibility of debris entering the interior of the glass melting furnace 200 and contaminating the molten glass, thus helping to maintain the quality of the glass, but also facilitates subsequent cleaning of the furnace body 110, thereby ensuring the long-term stable operation of the sealing device 100 without affecting the glass production efficiency and quality.

[0042] In some embodiments, see Figure 3 As shown, the sealing element 120 internally defines a receiving cavity 121. The sealing device 100 also includes thermal insulation material. The receiving cavity 121 is filled with thermal insulation material, so that when heat from the glass melting furnace 200 is transferred through the first opening 1111 to the second opening 1112, the sealing element 120 can have a good thermal insulation effect through the thermal insulation material, thereby reducing the heat transfer from the sealing element 120 to the external environment and improving the heat storage of the glass melting furnace 200. The thermal insulation material can be a cotton-like material, such as glass wool and rock wool, or ceramic fiber, or it can be a phase change material or nanomaterial. In this embodiment, the thermal insulation material is not limited.

[0043] In addition, or as a supplementary solution, the outer surface of the seal 120 can be covered with a heat-insulating material. The heat-insulating material not only further enhances the heat insulation effect of the seal 120, but also provides additional protection against damage from external environmental factors. In this embodiment, the heat-insulating material is metallic steel. Specifically, steel has a low insulation temperature and minimal high-temperature oxidation, effectively preventing heat loss and not affecting the molten glass inside the glass melting furnace 200. In other embodiments, the heat-insulating material can also be calcium silicate board, aerogel, etc., as long as the sealing device 100 can effectively reduce heat loss while maintaining good sealing performance.

[0044] Furthermore, in the second position, the spray gun 300 is located outside the active channel 111. By filling it with heat-insulating material or covering it with heat-insulating material, the heat from the glass melting furnace 200 will not pass through the seal 120 and act on the spray gun 300 (oxidative corrosion), thereby preventing the spray gun 300 from deforming or falling off.

[0045] Further, see Figure 3 As shown, in addition to the receiving cavity 121, the interior of the sealing member 120 also has multiple spaced-apart vent holes 122. The vent holes 122 are separated from the receiving cavity 121 and are independent of each other. By separating the vent holes 122 and the receiving cavity 121, the sealing member 120 can not only prevent heat loss from the glass melting furnace 200 through the insulation material in the receiving cavity 121, but also dissipate heat from itself through the vent holes 122. This prevents the sealing member 120 from deforming due to the temperature inside the glass melting furnace 200, which could lead to the second opening 1112 being unable to be closed.

[0046] Furthermore, the receiving cavity 121 is positioned between the furnace body 110 and the exhaust port 122, so that the receiving cavity 121 is located on the side of the sealing element 120 facing the movable channel 111 of the furnace body 110. This ensures that the sealing element 120 itself has good sealing and heat preservation effects, that is, it provides good heat insulation for the spray gun 300 and good heat storage for the glass melting furnace 200. At the same time, the exhaust port 122 is connected to the outside, so that the sealing element 120 itself also has good air permeability, ensuring the normal operation of the sealing device 100.

[0047] A second aspect of the present invention provides a glass production apparatus 10, see below. Figures 1 to 6 As shown, the glass production equipment 10 includes a glass melting furnace 200, a spray gun 300, and a sealing device 100 as described in any of the above embodiments. The glass melting furnace 200 defines a melting chamber 210 for holding molten glass and other substances to process glass. A furnace body 110 is connected to the glass melting furnace 200, and a first opening 1111 of the furnace body 110 communicates with the melting chamber 210. The spray gun 300 is movably connected to the furnace body 110 and can move relative to the furnace body 110 to make corresponding positional changes when the sealing element 120 is in a first position and a second position. In the first position, the spray gun 300 is positioned in the movable channel 111, and the nozzle 310 of the spray gun 300 is positioned at the first opening 1111 to heat the molten glass inside the glass melting furnace 200. In the second position, the spray gun 300 exits the movable channel 111 through a second opening 1112 to be positioned outside the movable channel 111.

[0048] In this embodiment of the glass production equipment 10, the spray gun 300 is movably positioned in the movable channel 111. When the spray gun 300 is heating, it can be spaced apart from the glass melting furnace 200, thereby reducing the oxidative corrosion of the spray gun 300 caused by the internal temperature of the glass melting furnace 200. When the spray gun 300 is not in operation, it exits the movable channel 111 through the second opening 1112. At this time, the sealing member 120 closes the second opening 1112, thereby isolating the external environment and the melting furnace chamber 210, thus preventing heat loss from the inside of the glass melting furnace 200.

[0049] Furthermore, in some embodiments, see [reference] Figure 5 and Figure 6 As shown, the glass production equipment 10 also includes a second drive device 320, which is connected to the spray gun 300. The second drive device 320 is used to drive the spray gun 300 to enter and exit the movable channel 111 through the second opening 1112. Specifically, the second drive device 320 is connected to the end of the spray gun 300 away from the furnace body 110, that is, the end opposite to the nozzle 310 of the spray gun 300. The second drive device 320 can be a cylinder or a motor, etc., and is not limited in this embodiment.

[0050] When the spray gun 300 requires maintenance or adjustment, the second drive device 320 will activate and drive the spray gun 300 out of the movable channel 111 to a more easily accessible position. After the spray gun 300 exits the movable channel 111, the second opening 1112 will close, preventing heat from the melting furnace chamber 210 from escaping and affecting the spray gun 300. In operation, the second drive device 320 drives the spray gun 300 through the movable channel 111 to a designated working position, allowing it to heat the glass melting furnace 200. By incorporating the second drive device 320, the automation level of the glass production equipment 10 is improved, and the need for manual intervention is significantly reduced, thereby enhancing the efficiency and safety of glass processing.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
