Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing equipment technology, and in particular to a substrate glass production equipment and its ring-type sealing baffle structure. Background Technology

[0002] During the production of substrate glass, the furnace needs to continuously feed raw materials through a continuous feeder. After the feeder has been running for a period of time, the internal spiral blades are prone to wear or glass material may adhere to them, resulting in a decrease in the amount of material fed and an increase in equipment vibration. It is necessary to clean the coke or replace the feeder.

[0003] In the existing technology, there are problems such as poor sealing, large heat radiation, and inconvenience in disassembly and assembly at the connection between the feeding machine and the furnace, which affect production safety and stability and urgently need to be improved. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a substrate glass production equipment and its ring-type sealing baffle structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A ring-type sealing baffle structure for substrate glass production equipment is installed on the outer wall of the sleeve of the feeding machine and abuts against the end face of the cylinder brick. The structure comprises: a first retaining ring, a second retaining ring, a connecting assembly, and a refractory filling layer. The first and second retaining rings are detachably fixed to the outer wall of the sleeve via the connecting assembly and together form an annular cavity. The refractory filling layer is disposed within the annular cavity, and one end face of the filling layer is in sealed contact with the end face of the cylinder brick.

[0006] Furthermore, the first retaining ring is provided with a boss, and the second retaining ring is provided with a groove that matches the boss. The boss and the groove cooperate to achieve docking and positioning of the first retaining ring and the second retaining ring.

[0007] Furthermore, the sidewall of the groove adjacent to the annular cavity protrudes into the interior of the annular cavity to compress the refractory filler layer in the axial direction, causing it to deform and form an interference fit with the annular cavity, thereby enhancing the sealing and isolating heat radiation.

[0008] Furthermore, the connecting assembly includes screws and nuts, with the screws passing through mounting holes respectively provided on the first retaining ring and the second retaining ring, and being locked by the nuts to achieve detachable fixing of the first retaining ring and the second retaining ring.

[0009] Furthermore, it also includes a tightening screw, which is installed on the feeding machine and is arranged parallel to the axial direction of the material cylinder. By screwing the tightening screw, one end of the tightening screw abuts against the outer wall of the first retaining ring / second retaining ring.

[0010] Furthermore, the refractory filling layer is high-temperature resistant ceramic fiber cotton or refractory brick.

[0011] Furthermore, the cross-sections of the first retaining ring and the second retaining ring are "L"-shaped, together forming the annular receiving cavity.

[0012] A substrate glass production apparatus includes the aforementioned ring-type sealing baffle structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Compared with existing technologies, by setting a refractory filling layer in the annular cavity and using the protrusions on the inner sidewall of the groove to axially compress the filling layer, the filling layer forms an interference fit with each contact surface. This effectively blocks the leakage of high-temperature gas in the furnace, isolates heat radiation, reduces heat loss, and protects the external components of the feeding machine. The first and second retaining rings are detachably connected by screws and nuts, allowing for separation of the retaining rings without overall disassembly, facilitating the replacement of the refractory filling layer or maintenance of the feeding machine. At the same time, the fit between the boss and the groove enables rapid positioning of the retaining ring, shortening assembly time. The setting of the tightening screw provides radial support to the retaining ring, offsetting the impact force of high-temperature gas and preventing the retaining ring from deforming. The "L"-shaped cross-section retaining ring improves the fit stability with the sleeve and the limiting effect on the filling layer. The selection of stainless steel connecting components and high-temperature refractory materials further adapts to high-temperature working environments and extends the overall service life of the structure.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4 As shown, this embodiment provides a ring-type sealing baffle structure for a substrate glass production equipment. It is installed on the outer wall of the sleeve of the feeding machine 5 and abuts against the end face of the material cylinder brick 7. The structure is characterized by including: a first baffle ring 1, a second baffle ring 2, a connecting component 4, and a refractory filling layer 3. The first baffle ring 1 and the second baffle ring 2 are detachably fixed to the outer wall of the sleeve through the connecting component 4 and together form an annular cavity. The refractory filling layer 3 is disposed in the annular cavity, and one end face of the refractory filling layer 3 is sealed against the end face of the material cylinder brick 7.

[0018] The first retaining ring 1 is provided with a boss 101, and the second retaining ring 2 is provided with a groove 201 that matches the boss 101. The boss 101 and the groove 201 cooperate to achieve docking and positioning of the first retaining ring 1 and the second retaining ring 2.

[0019] The groove 201 protrudes into the annular cavity from the side wall adjacent to the annular cavity, which is used to compress the refractory filling layer 3 in the axial direction, so that it deforms and forms an interference fit with the annular cavity, thereby achieving the effect of enhancing sealing and isolating heat radiation.

[0020] Overall, the first retaining ring 1 has an integrally formed boss 101 at its mating end, which extends circumferentially along the first retaining ring 1 and has a rectangular cross-section; the second retaining ring 2 has a groove 201 at its mating end that matches the boss 101, and the depth and width of the groove 201 are the same as the height and width of the boss 101. During assembly, the boss 101 can be completely embedded in the groove 201, realizing quick docking and positioning of the first retaining ring 1 and the second retaining ring 2, avoiding circumferential offset during assembly, and improving assembly efficiency; The sidewall (i.e., inner sidewall) of the groove 201 adjacent to the annular receiving cavity protrudes into the annular receiving cavity to form a limiting protrusion. This protrusion is continuously arranged along the circumference of the groove 201. When the first retaining ring 1 and the second retaining ring 2 are locked together by the connecting component 4, the limiting protrusion will generate an axial compressive force on the refractory filling layer 3 in the annular receiving cavity, forcing the refractory filling layer 3 to undergo elastic deformation, thereby forming an interference fit with the inner wall of the annular receiving cavity, the outer wall of the sleeve, and the end face of the material cylinder brick 7. This interference fit can not only eliminate the gaps between the components and enhance the sealing effect to prevent high-temperature gas leakage, but also further compact the refractory filling layer 3, improve its ability to isolate heat radiation, and reduce heat loss.

[0021] like Figures 1-2 As shown, in this embodiment, the connecting component 4 includes a screw 401 and a nut 402. The screw 401 passes through the mounting holes provided on the first retaining ring 1 and the second retaining ring 2 respectively, and is locked by the nut 402 to achieve detachable fixing of the first retaining ring 1 and the second retaining ring 2.

[0022] Specifically, the connecting component 4 includes a stainless steel screw 401 and a lock nut 402. The first retaining ring 1 and the second retaining ring 2 are symmetrically provided with mounting holes (two at each end). During assembly, the first retaining ring 1 and the second retaining ring 2 are fitted against the outer wall of the sleeve of the feeding machine 5 so that the mounting holes of the two are aligned. Then, the screw 401 is passed through the aligned mounting holes, and the lock nut 402 is screwed into the other end of the screw 401 and locked, so that the first retaining ring 1 and the second retaining ring 2 can be detachably fixed.

[0023] The advantages of this connection method are: the stainless steel material has good high temperature resistance and can adapt to the high temperature environment around the feeder 5; the anti-loosening nut 402 can prevent the connection from loosening due to equipment vibration and ensure structural stability; at the same time, the detachable screw 401 and nut 402 connection facilitates later maintenance - when it is necessary to replace the refractory filling layer 3 or repair the feeder 5, simply loosen the nut 402 and remove the screw 401 to separate the first retaining ring 1 and the second retaining ring 2 without disassembling the entire baffle structure, which greatly simplifies the operation process.

[0024] like Figure 4 As shown, in this embodiment, a tightening screw 8 is also included. The tightening screw 8 is installed on the feeding machine 5 and is arranged parallel to the axial direction of the material cylinder. By screwing the tightening screw 8, one end of the tightening screw 8 abuts against the outer wall of the first retaining ring 1 / second retaining ring 2.

[0025] Specifically, a tightening screw 8 is added to improve structural stability; a bracket for installing the tightening screw 8 is fixed on the frame of the feeding machine 5 (near the sleeve), the tightening screw 8 is installed on the bracket through a threaded hole, and the axis of the tightening screw 8 is parallel to the axis of the material cylinder; a total of 2-4 tightening screws 8 are provided, evenly distributed along the circumference of the sleeve, with one end facing the outer wall of the first retaining ring 1 or the second retaining ring 2.

[0026] After assembly, tighten the screw 8 so that the end facing the retaining ring is in close contact with the outer wall of the first retaining ring 1 or the second retaining ring 2, thereby forming a firm support for the retaining ring and making the refractory filling layer 3 in the annular cavity abut against the end face of the barrel brick 7. This structure can effectively offset the impact force of the high temperature gas in the furnace 6 on the retaining ring, prevent the retaining ring from deforming or displacing due to long-term stress, further ensure the stability of the sealing effect, and extend the service life of the baffle structure.

[0027] like Figures 1-2As shown, in this embodiment, the refractory filling layer 3 is high-temperature resistant ceramic fiber cotton or refractory brick.

[0028] Specifically, the material for the refractory filler layer 3 should be selected accordingly: Option 1: When the temperature at the connection between the feeder 5 and the furnace 6 is below 1600℃ and the sealing elasticity requirement is high, the refractory filling layer 3 is made of high-temperature resistant ceramic fiber cotton. This material has the characteristics of being soft and elastic. After being compressed by the limiting protrusion of the groove 201, it can tightly fit the contact surfaces of the annular cavity to form a good seal. At the same time, the ceramic fiber cotton has a low thermal conductivity and excellent heat insulation effect, which can effectively isolate the heat radiation of the furnace 6.

[0029] Option 2: When the temperature at the connection point exceeds 1600℃, or when the structural strength requirements of the filling layer are high, the refractory filling layer 3 shall be made of refractory bricks (such as high-alumina refractory bricks); the refractory bricks shall be filled into the annular cavity by splicing, which has strong high-temperature resistance, stable structure, and can withstand high-temperature environment for a long time without deformation; at the same time, high-temperature sealant can be applied between the refractory bricks and between the refractory bricks and the contact surface to further enhance the sealing effect.

[0030] like Figure 2 As shown, in this embodiment, the cross-sections of the first retaining ring 1 and the second retaining ring 2 are "L" shaped, and together they enclose the annular receiving cavity.

[0031] Specifically, the cross-sectional structure of the retaining ring is designed: The first retaining ring 1 and the second retaining ring 2 both have an "L" shaped cross section, including a radial section and an axial section: the radial section extends radially along the sleeve, and its inner sidewall fits against the outer wall of the sleeve; the axial section extends axially along the sleeve and is perpendicularly connected to one end of the radial section; when the first retaining ring 1 and the second retaining ring 2 are docked and fixed, the radial sections of the two together form the radial sidewall of the annular cavity, and the axial sections together form the axial sidewall of the annular cavity, thereby forming an annular cavity with an opening facing the material cylinder brick 7.

[0032] The advantages of the “L” shaped cross section design are: simple structure and easy to process; large contact area between the radial section and the outer wall of the sleeve, which can improve the connection stability between the retaining ring and the sleeve; and the axial section can form an axial limit on the refractory filling layer 3, preventing the filling layer from shifting away from the material cylinder brick 7 during use, and ensuring the reliability of the sealing contact.

[0033] This utility model embodiment also proposes a substrate glass production equipment, including any of the ring-type sealing baffle structures described in any one of the embodiments.
