Description

TECHNICAL FIELD

[0001] The utility model relates to glass production technical field especially is related to a nozzle device for float glass production. BACKGROUND

[0002] The forming process of float glass production is completed in a tin bath into which protective gas (N2 and H2) is introduced. Molten glass continuously flows from a pool furnace and floats on the surface of tin liquid with a relatively large specific gravity. Under the action of gravity and surface tension, the glass liquid spreads, flattens on the tin liquid surface, forms an upper and lower surface flat, hardens, and is drawn onto the transition roller table after cooling. The rollers of the roller table rotate to pull the glass ribbon out of the tin bath into the annealing lehr, and after annealing and cutting, the float glass product is obtained.

[0003] In the production process of float glass, the fire brick is used for flame spraying. Specifically, the glass batch is heated at high temperature in the pool furnace or crucible furnace to form a uniform, bubble-free and forming-required liquid glass. During this process, the furnace uses heavy oil as fuel (natural gas, producer gas, petroleum coke powder, etc. are also used), and the heat generated by the combustion of the fuel is transferred to the glass batch through the fire brick to melt it. The fire brick is a special-shaped brick used in oil-fired melting furnace, which is a channel for spraying the atomized heavy oil into the furnace and mixing with the combustion air.

[0004] Since the fire brick has a fire hole, the flame is sprayed through the fire hole, and the glass batch deposits ash on the hole wall during the melting process, causing the flame shape to be unstable and affecting the flame spraying range. INVENTION CONTENTS

[0005] The utility model aims at providing a nozzle device for float glass production, which solves the technical problem of unstable shape of the flame sprayed by the existing fire brick.

[0006] The present application provides a nozzle device for float glass production, which comprises a nozzle brick and a cleaning hook. The nozzle brick has a through fire hole, and the caliber of the fire hole gradually increases from the first side of the nozzle brick to the second side of the nozzle brick. The cleaning hook includes an operating rod and a cleaning block. One end of the operating rod is connected to the first position of the edge of the cleaning block. The cleaning block enters the fire hole through the first side of the nozzle brick and cleans the hole wall of the fire hole.

[0007] In one embodiment, the thickness of the cleaning block gradually increases in the direction away from the first position. Since the parts of the cleaning block away from the first position (i.e. the part connected to the operating rod) are mainly used for scraping and cleaning the hole wall of the fire hole, these parts will experience more physical wear and tear. Therefore, by increasing the thickness of these parts, the durability and service life of the cleaning block can be significantly improved.

[0008] In one embodiment, the cleaning block has a first surface and a second surface opposite in the thickness direction, the first surface is away from the main body of the operating rod, the first surface is perpendicular to the operating rod, and the second surface gradually approaches the main body of the operating rod in the direction away from the first position. The design of the downwardly inclined second surface enables the cleaning block to more effectively hook off the deposits when scraping the wall of the flame hole. As the cleaning block penetrates into the flame hole, the deposits are gradually pushed towards the orifice and are more easily hooked out due to the guidance of the inclined surface.

[0009] In one embodiment, the second surface is provided with a plurality of first cleaning ribs, and the plurality of first cleaning ribs are spaced apart in the direction away from the first position. The first cleaning ribs can significantly increase the friction between the cleaning block and the wall of the flame hole, thereby increasing the force of cleaning the deposits.

[0010] In one embodiment, the peripheral side wall of the cleaning block is provided with second cleaning ribs, and the second cleaning ribs are arranged along the circumference of the cleaning block to ensure the omnidirectional cleaning of the wall of the flame hole. This design can cover all corners of the wall of the flame hole, effectively remove the deposits, and avoid cleaning dead angles. The presence of the second cleaning ribs increases the contact area and friction between the cleaning block and the wall of the flame hole, thereby improving the cleaning effect.

[0011] In one embodiment, the number of the second cleaning ribs is two or more, and the two or more second cleaning ribs are spaced apart in the thickness direction.

[0012] In one embodiment, the operating rod comprises a first connecting rod and a second connecting rod, the first connecting rod is adjustably mounted at one end of the second connecting rod, and the other end of the second connecting rod is connected to the first position of the cleaning block. The design of the adjustably positioned first connecting rod enables the overall length of the operating rod to be adjusted according to the height of the operator, the width of the working area, and the specific requirements of the cleaning task, which helps the operator to maintain a comfortable operating posture in different working environments and improves the working efficiency. The adjustably positioned design enables the operator to quickly adjust the height and angle of the operating rod without the need to frequently change tools or perform complex adjustment operations, thereby improving the efficiency of the cleaning work, the operator can maintain a more natural and comfortable holding posture, and the hand and body fatigue caused by long-time work is reduced.

[0013] In one embodiment, the first connecting rod is threadedly connected to the second connecting rod.

[0014] In one embodiment, the end of the first connecting rod is provided with an operating cross beam.

[0015] In one of the embodiments, ceramic fiber sleeves are sleeved on both ends of the operating beam. In the float glass production process, the nozzle device can be in contact with high-temperature flame or molten glass, and the sleeving of the ceramic fiber sleeves can effectively protect the operating beam from high temperature and ensure the safety of the operator. At the same time, the ceramic fiber sleeves generally have good softness and elasticity, and can provide a more comfortable holding feeling.

[0016] In one of the embodiments, the operating rod is welded and fixed with the cleaning block.

[0017] In one of the embodiments, the material of the operating rod and / or the cleaning block is stainless steel. Stainless steel has high hardness and wear resistance, and can maintain the stability of its shape and size during a long cleaning process, so that the cleaning block can more effectively scrape and remove the deposits on the wall of the flame jet hole without losing the cleaning effect due to rapid wear. And the cleaning block made of stainless steel can maintain its structural integrity and functionality when in contact with high-temperature flame or molten glass, ensuring that the cleaning work can be carried out smoothly

[0018] The float glass production nozzle device provided by the utility model has the beneficial effects that: the flame jet hole diameter of the nozzle brick gradually increases from the first side to the second side, which helps to keep the flame stable during the jetting process and reduces the turbulence and irregularity of the flame when passing through the flame jet hole; one end of the operating rod is connected to the first position of the edge of the cleaning block, so that the cleaning radius of the cleaning block with the first position as the center is large, and the cleaning area is large; the operating rod controls the cleaning block to enter the inside of the flame jet hole, effectively cleaning the deposits on the wall of the hole, ensuring the smoothness of the flame jet hole, avoiding the influence of the accumulation of the deposits on the shape of the flame and the jetting range, solving the technical problem of unstable shape of the jetted flame of the existing flame jet brick, and ensuring that the nozzle device maintains a high-efficiency working state for a long time.

[0032] In combination Figure 1 And Figure 2 The application provides a nozzle device for float glass production. The nozzle device for float glass production comprises a nozzle brick 100 and a cleaning hook 200. The nozzle brick 100 has a through flame hole 101. The caliber of the flame hole 101 gradually increases from the first side 102 of the nozzle brick 100 to the second side 103 of the nozzle brick 100. The cleaning hook 200 comprises an operating rod 210 and a cleaning block 220. One end of the operating rod 210 is connected to the first position 221 of the edge of the cleaning block 220. The cleaning block 220 enters the flame hole 101 through the first side 102 of the nozzle brick 100 and cleans the hole wall of the flame hole 101.

[0033] The caliber of the flame hole 101 of the nozzle brick 100 gradually increases from the first side 102 to the second side 103, which helps to keep the flame stable during the spraying process and reduce the turbulence and irregularity of the flame when passing through the flame hole 101. One end of the operating rod 210 is connected to the first position 221 of the edge of the cleaning block 220, so that the cleaning block 220 has a large cleaning radius with the first position 221 as the center and a large cleaning area. The operating rod 210 controls the cleaning block 220 to enter the inside of the flame hole 101, effectively cleaning the deposits on the hole wall and ensuring the smoothness of the flame hole 101, avoiding the influence of the accumulation of deposits on the shape of the flame and the spraying range, and ensuring that the nozzle device can maintain a high-efficiency working state for a long time.

[0034] In some embodiments, in combination Figure 2 And Figure 3 The thickness of the cleaning block 220 gradually increases in the direction away from the first position 221. Since the parts of the cleaning block 220 away from the first position 221 (i.e. the part connected to the operating rod 210) are mainly used for scraping and cleaning the hole wall of the flame hole 101, these parts will experience more physical wear and tear. Therefore, by increasing the thickness of these parts, the durability and service life of the cleaning block 220 can be significantly improved.

[0035] In some embodiments, in combination Figure 2 And Figure 3The cleaning block 220 has a first surface 222 and a second surface 223 opposite in the thickness direction, the first surface 222 is away from the main body of the operating rod 210, the first surface 222 is perpendicular to the operating rod 210, and the second surface 223 gradually approaches the main body of the operating rod 210 in the direction away from the first position 221. The design of the second surface 223 being inclined downward enables the cleaning block 220 to more effectively hook off the deposits when scraping the hole wall of the flame hole 101. As the cleaning block 220 penetrates into the flame hole 101, the deposits are gradually pushed towards the hole and are more easily hooked off due to the guidance of the inclined surface.

[0036] In one of the embodiments, in combination with Figure 3 The second surface 223 is provided with a plurality of first cleaning ribs 224, and the plurality of first cleaning ribs 224 are spaced apart in the direction away from the first position 221. The first cleaning ribs 224 can significantly increase the friction between the cleaning block 220 and the hole wall of the flame hole 101, thereby increasing the force for cleaning the deposits.

[0037] Specifically, the first cleaning ribs 224 are linear, which facilitates sweeping the deposits and quickly cleaning the scraped deposits.

[0038] Specifically, the two ends of the first cleaning ribs 224 respectively extend to the opposite two sections of the second surface 223, so as to maximize the length of the first cleaning ribs 224 and increase the cleaning area.

[0039] Specifically, the interval between the adjacent two first cleaning ribs 224 gradually decreases in the direction away from the first position 221. Since the area of the cleaning block 220 away from the first position 221 (i.e. the part connected with the operating rod 210) is mainly used for scraping and cleaning the hole wall of the flame hole 101, these areas will experience more physical wear and tear, and the interval of the first cleaning ribs 224 in these areas is reduced, i.e. the density of the first ribs is increased, which is beneficial to enhancing the wear resistance of the position.

[0040] In one of the embodiments, in combination with Figure 3 The circumferential wall of the cleaning block 220 is provided with second cleaning ribs 225, and the second cleaning ribs 225 are arranged along the circumference of the cleaning block 220 and surround the cleaning block 220 once, which ensures the omnidirectional cleaning of the hole wall. This design can cover all corners of the hole wall, effectively remove the deposits, and avoid cleaning dead angles. The existence of the second cleaning ribs 225 increases the contact area and the friction between the cleaning block 220 and the hole wall, thereby improving the cleaning effect.

[0041] In one of the embodiments, in combination with Figure 3The number of the second cleaning ribs 225 is two or more, and the two or more second cleaning ribs 225 are distributed along the thickness direction. The plurality of second cleaning ribs 225 can more comprehensively contact and scrape the hole wall of the flame hole 101, increase the contact area and friction with the deposits, and thus more effectively remove the deposits.

[0042] In some embodiments, in combination with Figure 4 The operating rod 210 includes a first connecting rod 211 and a second connecting rod 212. The first connecting rod 211 is adjustably installed at one end of the second connecting rod 212, and the other end of the second connecting rod 212 is connected to the first position 221 of the cleaning block 220. The adjustable design of the first connecting rod 211 allows the overall length of the operating rod 210 to be adjusted according to the height of the operator, the width of the working area, and the specific requirements of the cleaning task, which helps the operator to maintain a comfortable operating posture in different working environments and improves the working efficiency. The adjustable design allows the operator to quickly adjust the height and angle of the operating rod 210 without the need to frequently change tools or perform complex adjustment operations, improving the efficiency of the cleaning work, and the operator can maintain a more natural and comfortable holding posture, reducing hand and body fatigue caused by long-time work.

[0043] In one of the embodiments, the first connecting rod 211 is threadedly connected to the second connecting rod 212. The threaded connection allows precise position adjustment of the first connecting rod 211 relative to the second connecting rod 212. The operator can easily adjust the threaded connection length of the first connecting rod 211 as needed to adapt to different working environments and cleaning tasks.

[0044] In one of the embodiments, in combination with Figure 1 , Figure 2 and Figure 4 The end of the first connecting rod 211 is provided with an operating beam 213. The operating beam 213 provides a wider and more comfortable holding surface, which helps to reduce the fatigue of the operator's hands when holding the tool for a long time. The design of the operating beam 213 helps to increase the control of the operator on the tool, so that the tool can be more stably maintained at the required position and angle during cleaning.

[0045] Specifically, the end of the second connecting rod 212 away from the cleaning block 220 has a beam accommodating portion 214. In use, the worker holds the operating beam 213 with one hand and holds the beam accommodating portion 214 with the other hand, and holds the first connecting rod 211 and the second connecting rod 212 with both hands at the same time, which ensures the stability of holding the operating rod 210 and reduces the instability of the tool caused by hand shaking during cleaning, thereby improving the accuracy and efficiency of cleaning.

[0046] In addition, when not in use, the first connecting rod 211 can be screwed into the second connecting rod 212 until the operating crossbeam 213 is accommodated in the crossbeam accommodating portion 214, shortening the length of the operating rod 210, facilitating storage, and avoiding the protrusion of the operating crossbeam 213, improving the storage safety.

[0047] In one of the embodiments, ceramic fiber sleeves are sleeved on both ends of the operating crossbeam 213. In the float glass production process, the nozzle device can be in contact with high-temperature flame or molten glass, and the sleeving of the ceramic fiber sleeves can effectively protect the operating crossbeam 213 from high temperature, ensuring the safety of the operator. At the same time, the ceramic fiber sleeves generally have good softness and elasticity, and can provide a more comfortable holding feeling.

[0048] In one of the embodiments, the operating rod 210 and the cleaning block 220 are welded and fixed, ensuring the connection strength between the operating rod 210 and the cleaning block 220, and avoiding tool failure or safety hazards caused by loose connection during use. There is no relative movement or gap between the welded and fixed operating rod 210 and the cleaning block 220, which enables the cleaning block 220 to more accurately transmit operating force when scraping the hole wall of the fire hole 101, improving the cleaning efficiency.

[0049] It can be understood that in other embodiments, the operating rod 210 and the cleaning block 220 are integrally formed, improving the overall strength of the cleaning hook 200, avoiding connection gaps, and avoiding assembly errors.

[0050] Specifically, the material of the operating rod 210 is stainless steel. Stainless steel can maintain stable performance in a high-temperature environment and is not easy to soften or melt, so that the operating rod 210 can maintain its structural integrity and functionality when contacting high-temperature flame or molten glass, ensuring the safety of the operator.

[0051] Specifically, the material of the cleaning block 220 is stainless steel. Stainless steel has high hardness and wear resistance, and can maintain the stability of its shape and size during a long cleaning process, so that the cleaning block 220 can more effectively scrape and remove deposits on the hole wall of the fire hole 101 without losing cleaning effect due to rapid wear. In addition, the cleaning block 220 made of stainless steel can maintain its structural integrity and functionality when contacting high-temperature flame or molten glass, ensuring that the cleaning work can be carried out smoothly.

[0052] Specifically, the material of the cleaning block 220 is stainless steel type 321.

[0053] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
