Description

Technical Field

[0001] This utility model relates to the field of float glass production technology, and in particular to a gate sealing device based on the flow channel of float glass. Background Technology

[0002] In the production process of float glass, the flow channel plays a crucial role, responsible for transporting molten glass from the furnace to the tin bath for subsequent forming processes. The gate, as a vital component controlling the flow rate and velocity of the molten glass, directly impacts the quality and efficiency of glass production due to its sealing performance. Traditional float glass flow channel gate sealing technology suffers from several shortcomings, as follows:

[0003] First, the choice of sealing materials is relatively limited and their performance is limited. Ordinary rubber or asbestos materials are usually used as sealing strips. These materials are prone to aging, hardening and deformation under high temperature environments, which leads to a rapid decline in sealing performance. When molten glass is flushed for a long time, the sealing strip cannot effectively resist its erosion, making it easy for molten glass to leak out from the gap between the gate and the flow channel wall. This not only wastes molten glass and increases production costs, but also causes the leaked molten glass to condense around the flow channel, requiring regular shutdowns for cleaning.

[0004] In addition, the traditional gate sealing structure is poorly designed. The sealing contact between the gate and the flow channel wall is simple, usually relying only on the elasticity of the sealing material for adhesion. It is difficult to maintain a stable and reliable sealing state under the harsh conditions of high temperature and glass liquid scouring. This can easily lead to the infiltration of external air into the flow channel and the entry of impurities into the glass liquid, thereby affecting the quality of flat glass. Utility Model Content

[0005] This utility model discloses a gate sealing device based on the flow channel of float glass. The operator picks up the positioning frame and the second sealing strip, and passes the positioning rods on both sides of the positioning frame through the sliding holes of the positioning ear plates on the cover plate. A retaining spring and a support spring are installed sequentially on the outside of the positioning rods, allowing the positioning frame to move flexibly up and down and rotate circumferentially on the positioning ear plates while maintaining a certain stability to ensure accurate positioning. The second sealing strip is then installed on the positioning frame, and the positioning frame is used to position the second sealing strip circumferentially and laterally. The position of the second sealing strip is adjusted to ensure it is tightly aligned with the gap of the gate plate. Under the action of the support spring, the second sealing strip applies a certain pressing force to the gap of the gate plate, ensuring effective sealing of the gap and preventing air from entering the flow channel.

[0006] The first aspect of this disclosure provides a gate sealing device based on a float glass flow channel, specifically including: a flow channel, a cover plate installed at the top of the flow channel, a sealing cover and a set of sealing structures installed on the outer side of the cover plate, a rotating hole and two sliding holes opened in the middle of the sealing cover, a sliding hole opened in the middle of the cover plate, a gate plate inserted inside the sliding hole, a positioning sleeve provided in the middle of the gate plate, a first sealing strip installed on each side of the gate plate with bolts, two vertical limiting rods installed at the top of the gate plate, and the sealing structure composed of a positioning frame and a second sealing strip.

[0007] Furthermore, two sliding grooves are provided on the inner side of the flow channel, and a set of sealing grooves are provided on the inner side of the sliding grooves. The sealing grooves are triangular in structure, and a set of blocking strips are provided on both sides of the first sealing strip. The blocking strips are triangular in structure, and the first sealing strip extends into the interior of the sliding groove. The blocking strips and the sealing grooves engage.

[0008] Furthermore, the bottom of the cover plate is provided with two positioning blocks, which are rectangular in structure and are installed inside the sliding groove on the inner side of the flow channel.

[0009] Furthermore, a stabilizing groove with bolt mounting holes is provided on each side of the gate. The stabilizing groove has a rectangular structure. A stabilizing block with bolt mounting holes is provided on one side of the first sealing strip. The stabilizing block is installed inside the stabilizing groove.

[0010] Furthermore, two stabilizing blocks are provided above the gate, and a positioning groove is opened on each side of the stabilizing block and the limiting rod. A retaining spring is installed at the position of the positioning groove, and the bottom of the limiting rod extends into the bolt mounting hole of the gate.

[0011] Furthermore, a set of symmetrically distributed positioning ear plates are provided above the cover plate. A sliding hole is opened above the positioning ear plate. A positioning rod is provided on each side of the positioning frame and the second sealing strip. Two sliding holes are opened above the positioning frame. A set of positioning rods passes through the interior of the sliding holes and a retaining spring and a support spring are installed on the outside.

[0012] Furthermore, a sealing ring is provided at the bottom of the sealing cover, and a sealing groove is opened at the top of the cover plate. The sealing ring and the sealing groove engage, and a set of mutually aligned threaded holes are opened between the cover plate and the sealing cover.

[0013] This utility model provides a gate sealing device based on the flow channel of float glass, which has the following beneficial effects:

[0014] The gate is sealed by a multi-seal device consisting of a uniquely designed first and second sealing strip and a sealing cover, which effectively prevents the leakage of molten glass and the entry of outside air into the flow channel. The triangular blocking strip of the first sealing strip tightly engages with the triangular sealing groove in the sliding groove of the flow channel. Combined with the tight fit of the second sealing strip to the gate gap under the action of the support spring, a reliable sealing line is formed, which greatly reduces the risk of molten glass leakage, reduces the waste of raw materials, and improves the yield and quality stability of glass production.

[0015] The various components, including the flow channels, cover plates, gates, sealing structures, and sealing covers, work together during installation, ensuring accurate positioning. The installation steps are clear and straightforward, facilitating quick installation and disassembly by operators. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] Example 1: Please refer to Figures 1 to 7 :

[0036] This utility model proposes a gate sealing device based on the flow channel of float glass, including: a flow channel 1, a cover plate 2 installed at the top of the flow channel 1, and two positioning blocks at the bottom of the cover plate 2. The positioning blocks are rectangular in structure and are installed inside the sliding groove on the inner side of the flow channel 1. With the cooperation of the positioning blocks, the flow channel 1 and the cover plate 2 can be accurately assembled. The installation steps of the flow channel 1 and the cover plate 2 are as follows: the flow channel 1 is positioned according to the layout requirements of the float glass production equipment to ensure that its horizontality and verticality meet the installation standards. A level and a plumb line are used for measurement and adjustment, and the error is controlled within the allowable range. The operator picks up the cover plate 2, aligns the positioning block at the bottom of it with the sliding groove on the inner side of the flow channel 1, and slowly lowers it so that the positioning block is completely embedded in the sliding groove, realizing the initial positioning of the cover plate 2 and the flow channel 1, ensuring that the two fit tightly without obvious gaps.

[0037] In this embodiment of the disclosure, reference is made to Figures 1 to 7As shown, a sealing cover 7 and a set of sealing structures 6 are installed on the outer side of the cover plate 2. A rotating hole and two sliding holes are opened in the middle of the sealing cover 7. A sliding hole is opened in the middle of the cover plate 2, and a gate plate 3 is inserted inside the sliding hole. A positioning sleeve is provided in the middle of the gate plate 3. The operator needs to install a threaded rod at the position of the positioning sleeve according to existing technology. Controlling the rotation of the threaded rod will achieve the lifting and lowering effect of the gate plate 3. A first sealing strip 4 is installed on each side of the gate plate 3 with bolts. A stabilizing groove with bolt mounting holes is opened on each side of the gate plate 3. The stabilizing groove has a rectangular structure. A stabilizing block with bolt mounting holes is provided on one side of the first sealing strip 4. The stabilizing block is installed... Inside the stabilizing groove, after the workers install bolts at the bolt mounting holes, the gate plate 3 and the first sealing strip 4 are stably assembled. Two sliding grooves are opened on the inner side of the flow channel 1, and a set of sealing grooves are opened on the inner side of the sliding grooves. The sealing grooves are triangular in structure. A set of blocking strips are provided on both sides of the first sealing strip 4. The blocking strips are triangular in structure. The first sealing strip 4 extends into the interior of the sliding grooves. The blocking strips and the sealing grooves engage. It can be concluded that the sliding groove achieves the effect of circumferential and lateral positioning of the gate plate 3 and the first sealing strip 4, so that the gate plate 3 can move stably up and down along the sliding groove. The first sealing strip 4, together with the blocking strips, can effectively isolate the float glass and prevent the float glass from penetrating the first sealing strip 4.

[0038] In this embodiment of the disclosure, reference is made to Figures 1 to 7 As shown, the installation steps of the gate plate 3 and the first sealing strip 4 are as follows: The worker takes the first sealing strip 4, then aligns one side of the first sealing strip 4 with the sliding groove of the liquid channel 1, and slowly inserts it, so that the blocking strip and the sealing groove gradually engage until the first sealing strip 4 is completely installed in the sliding groove. Align one side of the gate plate 3 with the installed first sealing strip 4, insert the stabilizing block on the first sealing strip 4 into the stabilizing groove of the gate plate 3, and use bolts to firmly fix the two together. Install the other side of the first sealing strip 4 and the gate plate 3 in the same way. Install two limit rods 5 on the top of the gate plate 3, insert the bottom of the limit rods 5 into the bolt mounting holes of the gate plate 3, and install snap rings in the positioning grooves on both sides of the locking block 301 and the limit rods 5 to fix the limit rods 5 firmly, so as to prevent the bolts between the gate plate 3 and the first sealing strip 4 from loosening.

[0039] In this embodiment of the disclosure, reference is made to Figures 1 to 7As shown, two vertical limiting rods 5 are installed above the gate plate 3. The sealing structure 6 is composed of a positioning frame 601 and a second sealing strip 602. The installation and debugging steps of the sealing structure 6 are as follows: the operator picks up the positioning frame 601 and the second sealing strip 602, and passes the positioning rods on both sides of the positioning frame 601 through the sliding holes of the positioning ear plate on the cover plate 2. The snap ring and the support spring are installed on the outside of the positioning rods in sequence, so that the positioning frame 601 can move up and down and rotate circumferentially on the positioning ear plate while maintaining a certain stability to ensure accurate positioning. The second sealing strip 602 is installed on the positioning frame 601. The positioning frame 601 is used to position the second sealing strip 602 circumferentially and laterally. The position of the second sealing strip 602 is adjusted so that it is tightly aligned with the gap of the gate plate 3. Under the action of the support spring, the second sealing strip 602 applies a certain pressure to the gap of the gate plate 3 to ensure that the gap can be effectively sealed and prevent air from entering the interior of the liquid channel 1.

[0040] In this embodiment of the disclosure, reference is made to Figures 1 to 7 As shown, two locking blocks 301 are provided above the gate plate 3. A positioning groove is opened on both sides of the locking block 301 and the limiting rod 5. A snap ring is installed at the positioning groove. The snap ring is made of a rigid material in the prior art. After installation, the snap ring can achieve the effect of stabilizing the installation position of the limiting rod 5. The bottom of the limiting rod 5 extends into the bolt mounting hole of the gate plate 3. Therefore, after the limiting rod 5 is installed, the bolt between the gate plate 3 and the first sealing strip 4 can be prevented from loosening.

[0041] In this embodiment of the disclosure, reference is made to Figures 1 to 7 As shown, a set of symmetrically distributed positioning ear plates are provided above the cover plate 2. A sliding hole is opened above the positioning ear plate. A positioning rod is provided on both sides of the positioning frame 601 and the second sealing strip 602. Two sliding holes are opened above the positioning frame 601. A set of positioning rods passes through the interior of the sliding holes and a retaining spring and a support spring are installed on the outside. With the cooperation of the positioning rods, the positioning ear plates can position the positioning frame 601 circumferentially and vertically. With the cooperation of the positioning rods, the positioning frame 601 can position the second sealing strip 602 circumferentially and laterally. With the cooperation of the support spring and the positioning frame 601, a pressing force and a pushing force are applied to the second sealing strip 602 respectively, so that the second sealing strip 602 can better seal the gap of the gate plate 3 and prevent air from entering the interior of the flow channel 1 through the gap.

[0042] In this embodiment of the disclosure, reference is made to Figures 1 to 7As shown, a sealing ring is provided at the bottom of the sealing cover 7, and a sealing groove is opened at the top of the cover plate 2. The sealing ring and the sealing groove are engaged. A set of threaded holes are opened between the cover plate 2 and the sealing cover 7. After the operator installs the bolts at the positions of the threaded holes, the sealing cover 7 seals the top of the cover plate 2 and further seals the gate plate 3. The sealing cover 7 is placed on the cover plate 2 so that the sealing ring at the bottom of the sealing cover 7 is accurately engaged with the sealing groove on the cover plate 2. Then the threaded holes on the sealing cover 7 and the cover plate 2 are aligned and the two are firmly connected with bolts to ensure that the sealing cover 7 effectively seals the top of the cover plate 2 and further enhances the sealing effect on the gate plate 3, preventing external air, dust and other impurities from entering the interior of the flow channel 1.

[0043] In this embodiment of the disclosure, reference is made to Figures 1 to 7 As shown, inspect the interior of the flow channel 1 to ensure it is free of debris, dust, and glass residue. The two sliding grooves and sealing grooves on its inner side should be intact and undamaged, with dimensions meeting design requirements and smooth, flat surfaces to ensure the installation accuracy and sealing effect of subsequent components. Inspect the gate 3 to confirm its structural integrity, the central positioning sleeve's ability to rotate freely, the two side stabilizing grooves' lack of deformation, and the clear, undamaged threads of the bolt mounting holes. Simultaneously, check the integrity of the first sealing strip 4; the two triangular blocking strips on both sides should be free of deformation and damage, and the material should meet the requirements for high temperature and corrosion resistance. The stabilizing block on one side should be intact, and the bolt mounting hole positions should be accurate. Inspect the cover plate 2; the two bottom positioning blocks should be unworn, their dimensions matching the sliding grooves of the flow channel 1, the upper positioning ear plate secure, the sliding holes unblocked, and the surface free of deformation and cracks. The positioning frame 601 and the second sealing strip 602 in the sealing structure 6 should be intact, the positioning rod straight without bending, the retaining spring and support spring's elasticity normal, and the second sealing strip 602 free from aging and deformation. The sealing ring of the sealing cover 7 is intact and undamaged, the threaded hole is clear, and the rotating hole and sliding hole are not deformed.

[0044] Example 2, based on Example 1, with reference to Figures 1 to 7 As shown, the material of the first sealing strip 4 is improved by using fluororubber with added high-temperature stabilizing additives, and a layer of high-temperature resistant metal wire mesh is embedded inside it to enhance its overall structural strength and high-temperature resistance. At the same time, the surface of the sealing groove is treated with a special coating using a ceramic coating that can form a dense anti-oxidation layer at high temperatures, further reducing the coefficient of friction between the sealing groove and the blocking strip, reducing wear, and improving sealing performance.

[0045] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
