Description

Technical Field

[0001] This application relates to the field of glass processing technology, and in particular to a bubbling device for a glass furnace and a glass production line. Background Technology

[0002] In the glass furnace production process, the bubbling device plays a crucial role. It can effectively control, enhance and improve the convection of molten glass in the furnace, and improve the melting, clarification and homogenization efficiency of molten glass during the glass formation process.

[0003] Currently, bubbling devices typically use a combination of rubber hoses and metal pipes to connect the bubbling chamber to the bottom of the kiln. However, in practical applications, the complex environment at the bottom of the kiln means that the metal pipes are prone to overlapping with the steel structure at the bottom of the kiln. This results in low insulation between the metal pipes and the steel structure, causing the bubbling pipes to be directly connected to the ground. This accelerates heat conduction at the bottom of the kiln, leading to uneven temperature distribution of the molten glass in the kiln, disrupting the temperature gradient, and affecting the melting, clarification, and homogenization of the glass, thereby reducing the quality of the glass. Utility Model Content

[0004] This application mainly provides a bubbling device for a glass furnace and a glass preparation device, which solves the problem that the metal tubes easily overlap with the steel structure at the bottom of the furnace, causing the bubbling tubes to be directly connected to the ground.

[0005] This application provides a bubbling device for a glass furnace, comprising:

[0006] Bubble cabinet;

[0007] An outlet pipe is installed on the bubbling chamber, and one end of the outlet pipe is connected to the bubbling chamber.

[0008] A flexible hose, one end of which is connected to the other end of the outlet pipe;

[0009] A connecting pipe, one end of which is connected to the other end of the flexible hose;

[0010] Bubbling tubes are installed inside the bottom of the glass furnace;

[0011] An insulating component is disposed between the bottom secondary beam of the glass furnace and the connecting pipe. The other end of the connecting pipe passes through the insulating component and is connected to one end of the bubbling pipe through the bottom of the glass furnace. The other end of the bubbling pipe is used to introduce gas.

[0012] The connecting pipeline includes a first metal tube, a heat shrink tubing, and an oxygen tube. The heat shrink tubing is fitted over the first metal tube, and the oxygen tube is fitted over the heat shrink tubing.

[0013] The difference between the inner diameter of the heat shrink tubing and the outer diameter of the first metal tube is between 2 and 4 mm.

[0014] The connecting pipeline further includes multiple insulating layers, which are spaced apart along the length of the connecting pipeline on the outer surface of the oxygen pipe.

[0015] The plurality of insulating layers are wound around the oxygen pipe, and the spacing between two adjacent insulating layers is between 200 and 300 mm.

[0016] The outlet pipeline includes a second metal pipe, the length of which is between 45 and 55 mm.

[0017] The length of the hose is between 200 and 300 mm.

[0018] The insulating component includes an insulating plate, the thickness of which ranges from 5 to 20 mm.

[0019] The bubbling device further includes a fixing member and a connecting member. The fixing member connects the connecting pipe and the insulating member respectively, and is used to fix the connecting pipe to the insulating member when the other end of the connecting pipe passes through the insulating member. The connecting member connects one end of the bubbling tube and the other end of the connecting pipe respectively, so that one end of the bubbling tube and the other end of the connecting pipe are connected.

[0020] This application also provides a glass production line, including a glass furnace and the aforementioned bubbling device.

[0021] The beneficial effects of this application are as follows: The bubbling device of this application includes a bubbling cabinet, an outlet pipe, a hose, a connecting pipe, an insulating component, and a bubbling tube. The outlet pipe is installed on the bubbling cabinet, and one end of the outlet pipe is connected to the bubbling cabinet. The hose is connected to the other end of the outlet pipe on the bubbling cabinet and is connected to the bubbling tube inside the bottom of the glass furnace through the connecting pipe, thereby connecting the bubbling cabinet and the bubbling tube. The connecting pipe passes through the insulating component installed between the connecting pipe and the bottom secondary beam of the glass furnace. By installing the insulating component on the bottom secondary beam of the glass furnace, this application allows one end of the connecting pipe to pass through the insulating component and connect to the bubbling tube, avoiding overlap between the connecting pipe and the steel structure at the bottom of the furnace. This effectively improves the insulation between the connecting pipe and the steel structure of the glass furnace, thereby reducing the problem of the bubbling tube being connected to the ground, and thus improving the quality of the glass.

[0034] See Figure 1 As shown, Figure 1This is a schematic diagram of an embodiment of the existing bubbling device provided in this application. The bubbling device 100 of this embodiment includes a bubbling chamber 101, an outlet pipe 102, a rubber hose 103, a metal pipe 104, a secondary beam of the furnace 105, a fixing device 106, a buckle 107, refractory material at the bottom of the furnace 108, a clamping sleeve 109, and a bubbling tube 110. The outlet pipe 102 is mounted on the bubbling chamber 101. One end of the rubber hose 103 is connected to the outlet pipe 102, and the other end of the rubber hose 103 is connected to one end of the metal pipe 104. The other end of the metal pipe 104 passes through the refractory material at the bottom of the glass furnace 108 and is connected to the bubbling tube 110 via the clamping sleeve 109. The bottom of the glass furnace is provided with a secondary beam 105, and a fixing device 106 is provided on the secondary beam 105. The metal pipe 104 is fixed to the fixing device 106 by a buckle 107 so that the metal pipe 104 is fixed on the secondary beam 105.

[0035] Figure 1 The existing bubbling device 100 shown uses a combination of rubber hose 103 and metal pipe 104 to connect the bubbling cabinet 101 and the bubbling tube 110. In practical applications, in the complex environment at the bottom of the kiln, the metal pipe 104 is prone to overlapping with the steel structure at the bottom of the kiln. That is, the insulation between the metal pipe 104 and the steel structure at the bottom of the kiln is low, causing the bubbling tube 110 to be directly connected to the ground. This accelerates heat conduction at the bottom of the kiln, resulting in uneven temperature of the molten glass in the kiln, disrupting the temperature gradient, affecting the melting, clarification, and homogenization of the glass, and thus reducing the quality of the glass.

[0036] This application provides a bubbling device for a glass furnace; please refer to [link / reference]. Figure 2 As shown, Figure 2 This is a schematic diagram of an embodiment of the bubbling device for a glass furnace provided in this application. The bubbling device 1 of this embodiment includes a bubbling cabinet 10, an outlet pipe 20, a flexible hose 30, a connecting pipe 40, an insulating component 50, and a bubbling tube 60.

[0037] The outlet pipe 20 is installed on the bubbling chamber 10, with one end connected to the bubbling chamber 10. That is, the outlet pipe 20 serves as an interface for connecting the bubbling chamber 10 to other structures, such as the flexible hose 30. The bubbling chamber 10 is a structure used to store the gas that provides the bubbling effect, and is typically cabinet-shaped.

[0038] One end of the hose 30 is connected to the other end of the outlet pipe 20. The hose 30 includes, but is not limited to, a rubber hose. The connection method between the hose 30 and the outlet pipe 20 includes, but is not limited to, flange connection, clamp connection, crimping, or adhesive bonding.

[0039] One end of the connecting pipe 40 is connected to the other end of the hose 30, that is, the outlet pipe 20 is connected to the connecting pipe 40 through the hose 30. The connection methods between the connecting pipe 40 and the hose 30 include, but are not limited to, flange connection, clamp connection, crimping or bonding.

[0040] The bubbling tube 60 is disposed inside the bottom of the glass furnace (not shown in the figure), that is, the bubbling tube 60 is installed at the bottom of the glass furnace. In some embodiments, the bubbling tube 60 is placed in the inner cavity of the furnace in the bottom region of the glass furnace, so that it is in direct contact with the molten glass in the glass furnace.

[0041] An insulating component 50 is installed between the bottom secondary beam 70 of the glass furnace and the connecting pipe 40. The other end of the connecting pipe 40 passes through the insulating component 50 and connects to one end of the bubbling pipe 60 at the bottom of the glass furnace. The other end of the bubbling pipe 60 is used for gas introduction. The bottom secondary beam 70, also called the furnace secondary beam, typically bears the weight of the glass furnace and supports the stability of the structure. The bottom secondary beam 70 is usually designed with a steel structure to ensure sufficient strength and stability to support the structure and operation of the glass furnace; that is, the bottom secondary beam 70 is the bottom steel structure of the glass furnace.

[0042] Optionally, the glass furnace is provided with at least one bottom secondary beam 70, which is also called a main beam and is I-shaped. For example, as Figure 2 As shown, the glass furnace in this embodiment has four bottom secondary beams 70. In other embodiments, the number of bottom secondary beams 70 of the glass furnace can be designed according to the actual needs of the glass furnace, including but not limited to five or six.

[0043] In some embodiments, the insulating member 50 is fixed to the bottom secondary beam 70 of the glass furnace, such that the insulating member 50 is positioned between the bottom secondary beam 70 of the glass furnace and the connecting pipe 40. For example, as Figure 2 As shown, the two ends of the insulating member 50 are respectively connected to the bottom secondary beam 70 so that the insulating member 50 is fixed on the bottom secondary beam 70 of the glass furnace, and the insulating member 50 is located between the bottom secondary beam 70 of the glass furnace and the connecting pipe 40.

[0044] In some embodiments, one end of the connecting pipe 40 is connected to the hose 30, and the other end of the connecting pipe 40 passes through the insulator 50 and the bottom of the glass furnace and is connected to one end of the bubbling pipe 60. At this time, the bubbling cabinet 10 is connected to the bubbling pipe 60 through the outlet pipe 20, the hose 30, and the connecting pipe 40. The bubbling cabinet 10 delivers gas to the bubbling pipe 60 so that the other end of the bubbling pipe 60 is supplied with gas to the bottom of the glass furnace. The connecting pipe 40 is fitted with and connected to the insulator 50 to ensure the insulation of the connecting pipe 40 and prevent the connecting pipe 40 from contacting the bottom secondary beam 70 of the glass furnace.

[0045] The connection methods between the connecting pipe 40 and the bubbling pipe 60 include, but are not limited to, sleeve, flange, thread or welding.

[0046] In some embodiments, the bottom of the glass furnace is also provided with a bottom refractory material (not shown in the figure), which helps to reduce heat loss at the bottom of the glass furnace, maintain the stability of the temperature inside the glass furnace, and improve energy efficiency.

[0047] In this embodiment, by installing an insulating component 50 on the bottom secondary beam 70 of the glass furnace, one end of the connecting pipe 40 passes through the insulating component 50 and connects to the bubbling pipe 60, forming a gap between the connecting pipe 40 and the bottom secondary beam 70. This prevents the connecting pipe 40 from overlapping with the steel structure at the bottom of the furnace, effectively improving the insulation between the connecting pipe 40 and the steel structure of the glass furnace. This reduces the possibility of the bubbling pipe 60 being connected to the ground, thereby improving the quality of the glass.

[0048] According to some embodiments of this application, the bubbling device 1 further includes a fixing member 80 and a connecting member 90. The fixing member 80 includes, but is not limited to, a buckle; the connecting member 90 includes, but is not limited to, a retaining sleeve.

[0049] The fastener 80 connects the connecting pipe 40 and the insulating component 50 respectively, and is used to fix the connecting pipe 40 to the insulating component 50 when the other end of the connecting pipe 40 passes through the insulating component 50.

[0050] In some embodiments, such as Figure 2 As shown, the fastener 80 is a snap-fit. When the connecting pipe 40 passes through the insulating part 50, it is fixed to the insulating part 50 by the fastener 80, so as to avoid the connecting pipe 40 from overlapping with the bottom steel structure of the glass furnace and improve the insulation performance.

[0051] The connector 90 connects one end of the bubbling tube 60 and the other end of the connecting pipe 40, so that one end of the bubbling tube 60 and the other end of the connecting pipe 40 are connected.

[0052] In some embodiments, such as Figure 2 As shown, connector 90 is a compression fitting, and connecting pipe 40 is connected to one end of bubbling tube 60 through connector 90.

[0053] According to some embodiments of this application, please refer to Figure 3 As shown, Figure 3 yes Figure 2 A cross-sectional schematic diagram of one embodiment of the connecting pipe. The connecting pipe 40 in this embodiment includes a first metal pipe 401, a heat shrink tubing 402, and an oxygen pipe 403.

[0054] The first metal tube 401 is the core part of the connecting pipe 40. The first metal tube 401 includes, but is not limited to, copper or stainless steel tubes, and is used to transmit gas to the bubbling tube 60.

[0055] In some embodiments, the first metal pipe 401 of the connecting pipe 40 is a copper pipe with an inner diameter of 8 mm and a wall thickness of 1 mm.

[0056] Heat shrink tubing 402 is fitted onto the first metal tube 401. Heat shrink tubing 402 is a material that shrinks when heated and typically has insulating and protective functions.

[0057] In some embodiments, the heat shrink tubing 402 wraps around the first metal tube 401, and the heat shrink tubing 402 is heated to tighten it so that the heat shrink tubing 402 fits tightly against the surface of the first metal tube 401, thereby realizing that the heat shrink tubing is sleeved on the first metal tube 401, and the heat shrink tubing 402 provides insulation and protection for the first metal tube 401.

[0058] Oxygen tubing 403 is fitted over heat-shrink tubing 402. Oxygen tubing 403 is typically made of heat- and chemically resistant materials to provide physical protection.

[0059] In some embodiments, the oxygen tube 403 is cut in half from the middle, and a first metal tube 401 fitted with a heat shrink tubing 402 is placed inside the oxygen tube 403 so that the oxygen tube 403 is fitted onto the heat shrink tubing 402.

[0060] The connecting pipe 40 in this embodiment includes a first metal pipe 401, a heat shrink tubing 402, and an oxygen tubing 403. By sleeved with the heat shrink tubing 402, the first metal pipe 401 can be provided with good insulation performance. By sleeved with the oxygen tubing 403, the first metal pipe 401 is further provided with insulation protection and is protected from damage by the external environment. Moreover, due to the protective effect of the heat shrink tubing 402 and the oxygen tubing 403, the wear and corrosion rate of the first metal pipe 401 is reduced, thereby reducing maintenance costs and replacement frequency.

[0061] According to some embodiments of this application, the difference between the inner diameter of the heat shrink tubing 402 and the outer diameter of the first metal tube 401 is between 2 and 4 mm.

[0062] In some embodiments, the first metal tube 401 is first wrapped with a heat shrink tube 402 with an inner diameter 2 to 4 mm larger than the outer diameter of the first metal tube 401. The heat shrink tube 402 is heated and tightened so that it fits tightly against the surface of the first metal tube 401.

[0063] For example, the first metal tube 401 has an inner diameter of 10 mm and a wall thickness of 1 mm. The first metal tube 401 is wrapped with a heat shrink tube 402 with an inner diameter of 12 mm. The heat shrink tube 402 is heated with a hot air gun. After the heat shrink tube 402 shrinks, it completely adheres to the surface of the first metal tube 401. After the heat shrink tube 402 shrinks to a certain extent, the heating is stopped, and the heat shrink tube 402 cools and solidifies naturally, so that the heat shrink tube 402 is fitted onto the first metal tube 401.

[0064] In some embodiments, after the connecting pipe 40 is connected to the hose 30 and the bubbling tube 60 respectively, the bubbling cabinet 10 and the bubbling tube 60 are connected through the outlet pipe 20, the hose 30 and the connecting pipe 40; at this time, the resistance to ground is measured using a hand crank, and the resistance to ground meets the requirement of being greater than or equal to 1 megohm.

[0065] In this embodiment, a heat shrink tubing 402 with an inner diameter 2 to 4 mm larger than the outer diameter of the first metal tube 401 is selected. The difference range of 2 to 4 mm allows the heat shrink tubing 402 to shrink evenly during heating, avoiding local over-tightness or over-looseness. This ensures that the heat shrink tubing 402 can fit tightly against the first metal tube 401 after heating, forming a good sealing effect, preventing gas leakage, and thus ensuring the sealing and stability of the connecting pipe 40.

[0066] According to some embodiments of this application, the connecting conduit 40 further includes multiple insulating layers (not shown). These insulating layers include, but are not limited to, polyphenylene sulfide film, polyimide film, or polyvinyl chloride (PVC) insulating tape.

[0067] Multiple insulating layers are spaced apart along the length of the connecting pipe 40 on the outer surface of the oxygen pipe 403.

[0068] In some embodiments, the insulating layer is PVC insulating tape, which is wrapped and fixed on the outer surface of the oxygen tube 403, and multiple insulating layers are wrapped at intervals on the outer surface of the oxygen tube 403 along the length of the connecting pipe 40.

[0069] In this embodiment, multiple insulating layers are provided on the outer surface of the oxygen pipe 403 of the connecting pipe 40. By providing the insulating layers, the oxygen pipe 403 is protected from the physical and chemical effects of the external environment, extending the service life of the connecting pipe 40. Furthermore, the insulation protection of the first metal pipe 401 is improved, preventing the overall insulation performance of the glass furnace from being affected by the connecting pipe 40 contacting other steel structures.

[0070] According to some embodiments of this application, multiple insulating layers are wound around the oxygen pipe 403, and the spacing between two adjacent insulating layers ranges from 200 to 300 mm.

[0071] In some embodiments, an insulating layer is provided at intervals of 200-300 mm along the length of the oxygen tube 403, and the insulating layer is wrapped around the outer surface of the oxygen tube 403.

[0072] In this embodiment, the spaced insulating layers help to distribute heat evenly along the length of the connecting pipe 40, avoiding local overheating, thereby reducing heat loss and thermal stress on the connecting pipe 40.

[0073] According to some embodiments of this application, the outlet pipe 20 includes a second metal pipe, the length of which ranges from 45 to 55 mm.

[0074] The second metal tube includes, but is not limited to, a copper tube with a length ranging from 45 to 55 mm, for example, a copper tube with a length of 50 mm. The second metal tube is fixed to the bubbling chamber 10, and the fixing method includes, but is not limited to, welding, flange connection, or threaded connection.

[0075] In some embodiments, such as Figure 2 As shown, one end of the second metal tube is set on the bubbling chamber 10 and is connected to the bubbling chamber 10; the other end of the second metal tube is inserted into the hose 30 with an insertion distance of 30-50mm, and is fixed by hose clamp or clamp to connect the outlet pipe 20 and the hose 30, ensuring good airtightness between the outlet pipe and the hose 30.

[0076] According to some embodiments of this application, such as Figure 2 As shown, the length of the hose 30 in this embodiment ranges from 200 to 300 mm.

[0077] In some embodiments, a 300mm long flexible hose 30 is used to connect to the outlet pipe 20 and the connecting pipe 40 respectively, and both the outlet pipe 20 and the connecting pipe 40 are fixed after being inserted into the flexible hose 30. Figure 2 As shown.

[0078] In this embodiment, the length of the flexible hose 30 is between 200 and 300 mm. The bubbling device 1 in this embodiment... Figure 1 Compared to the bubbling device 100, the hose 30 is shorter, which means that the hose 30 has been optimized to keep it in a low-temperature environment and avoid affecting the overall insulation performance of the glass furnace due to aging and falling off.

[0079] According to some embodiments of this application, the insulating element 50 includes an insulating plate with a thickness ranging from 5 to 20 mm.

[0080] In some embodiments, the two ends of the insulating plate are respectively fixed to the two bottom secondary beams 70 of the glass furnace by structural steel, and the connecting pipe 40 passes through the insulating plate and the bottom of the glass furnace and is connected to one end of the bubbling pipe 60.

[0081] Optionally, the performance requirements for the insulating board include: the thickness of the insulating board is between 5 and 200 mm; the heat resistance temperature of the insulating board is 500°C; and the bending strength of the insulating board is greater than or equal to 45 MPa under normal temperature and perpendicular to the layer conditions. For example, the thickness of the insulating board in this embodiment is 20 mm.

[0082] In this embodiment, the thickness of the insulating board ranges from 5 to 20 mm. This thickness range helps to improve the durability of the insulating board, making it less prone to aging or deterioration during long-term use, thus extending its service life. Furthermore, it controls costs while meeting performance requirements, achieving the best balance between economic benefits and performance.

[0083] This application also provides a glass production line, including a glass furnace and the bubbling device 1 of the above embodiments, which will not be described in detail here.

[0084] In summary, this application improves the insulation between the connecting pipe 40 and the glass furnace by installing an insulating component 50 on the bottom secondary beam 70, allowing one end of the connecting pipe 40 to pass through the insulating component 50 and connect to the bubbling pipe 60. This avoids overlap between the connecting pipe 40 and the steel structure at the bottom of the furnace, effectively improving the insulation between the connecting pipe 40 and the steel structure of the glass furnace. This reduces the possibility of the bubbling pipe 60 being connected to the ground, thereby improving the quality of the glass. By optimizing the length of the flexible hose 30, it prevents it from aging and falling off, thus avoiding affecting the overall insulation of the glass furnace. Furthermore, by covering the surface of the first metal tube 401 of the connecting pipe 40 with a heat shrink tubing 402 and an oxygen tube 403, the overall insulation of the bubbling device 1 is improved.

[0085] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
