Description
TECHNICAL FIELD
[0001] The utility model relates to float glass production technical field especially is related to a kind of float glass annealing lehr air nozzle cleaning tool. BACKGROUND
[0002] The forming process of float glass production is completed in tin bath with protective gas (N2 and H2) being passed in. Molten glass flows continuously from the pool furnace and floats on the surface of tin liquid with relatively high density. Under the action of gravity and surface tension, the glass liquid spreads on the tin liquid surface, flattens, forms an upper and lower surface, hardens and cools, and is then introduced onto the transition roller table. The rollers of the roller table rotate to pull the glass ribbon out of the tin bath and into the annealing lehr, where it is annealed and cut to obtain the float glass product.
[0003] In the production process of float glass products, the annealing of glass is carried out in the annealing lehr. The glass sheet passes through the transition roller table and enters the annealing lehr (at this time, the temperature of the glass sheet is about 600°C). After the glass sheet leaves the end of the annealing lehr and enters the cold end roller, it is cut (at this time, the temperature of the glass sheet is about 70°C). In the entire annealing area, the glass sheet cools from a high temperature state to room temperature. During the cooling process, thermal stress is inevitably generated. The purpose of annealing of float glass is to control the cooling speed at different stages of the cooling process of the glass sheet to make the annealed glass sheet easy to cut and the residual stress within the required range. During the cooling process, if the local temperature of the glass sheet is higher than that of other places, it is easy to cause local cutting of the glass sheet to appear undesirable phenomena.
[0004] The annealing lehr is generally divided into seven parts along the length direction, including uniform heating zone (A zone), important annealing zone (B zone), post-annealing zone (C zone), transition zone of thermal insulation and non-thermal insulation (D zone), hot air circulation cooling zone (Ret zone), transition zone (E zone) and forced cooling zone (F zone). The cooling air of the F zone fan is directly blown onto the glass sheet. Above the glass sheet, each air pipe supplies the upper air nozzle of the annealing lehr along the movement direction of the glass sheet, and each air pipe is adjusted by a manual valve. Below the glass sheet, each air pipe supplies the lower air nozzle of the annealing lehr along the movement direction of the glass sheet, and each air pipe is adjusted by a louver valve. The air pipe adjustment valve is controlled through the operation panel on both sides of the annealing lehr. The air nozzle spacing is consistent with the roller spacing. The air volume generated by the F zone fan directly provides cooling air to the glass sheet from the air nozzle.
[0005] However, after long-term use of the air nozzle, dust and glass debris are accumulated in the air nozzle, which can cause the air volume to decrease and the air nozzle to be blocked. The increase in the local temperature of the glass sheet or the transverse temperature caused by the decrease in air volume can cause stress unevenness, resulting in glass sheet explosion or poor cutting quality.
[0006] In the related art, in order to clean the F zone tuyere of the annealing furnace, a hook, a steel sheet or a large shovel is generally used to knock and vibrate the tuyere so that the dust and sundries in the tuyere fall off. However, the cleaning effect is not thorough enough. Content of the utility model

[0040] In combination Figure 1 And Figure 2 The float glass annealing furnace 1 air nozzle 50 cleaning tool 10 provided by the embodiment comprises a first pipe 100, an air inlet assembly 200 and an air outlet assembly 300. The first pipe 100 has a first end 101 and a second end 102. The inside of the first pipe 100 has an air duct 103 communicating the first end 101 and the second end 102. The first end 101 is provided with the air inlet assembly 200, and the air inlet assembly 200 is used to provide air flow to the first pipe 100. The second end 102 is provided with the air outlet assembly 300, and the air outlet assembly 300 has an air outlet hole 301.
[0041] The air inlet assembly 200 provides air flow to the first pipe 100, the air flow flows to the air outlet assembly 300 through the air duct 103 of the first pipe 100, and the air outlet hole 301 of the air outlet assembly 300 is aligned with the air nozzle 50 of the annealing furnace 1, thereby realizing efficient cleaning of the air nozzle 50 of the annealing furnace 1. The air flow can effectively remove the accumulated dust and sundries in the air nozzle 50, ensure the smooth flow of the air in the air nozzle 50, thereby improving the working efficiency of the annealing furnace 1, and solving the technical problem that the cleaning effect of the air nozzle 50 of the existing annealing furnace 1 needs to be improved.
[0042] Specifically, in combination Figure 2 The annealing furnace 1 comprises a conveying roller 30 arranged in a rolling manner, which is used to move the glass plate 20 in the direction A. The air nozzle 50 is arranged on the upper and lower sides of the conveying roller 30, which is used to cool the glass plate 20. The side seal 40 is arranged on the left and right sides of the conveying roller 30. The float glass annealing furnace 1 air nozzle 50 cleaning tool 10 provided by the embodiment passes through the side opening 41 of the side seal 40 from the left and right sides to reach the conveying roller 30, and the air outlet hole 301 is aligned with the air nozzle 50. The air flow is blown to the air nozzle 50, thereby cleaning the air nozzle 50, and the dust and glass debris in the air nozzle 50 are removed, which is convenient to operate and efficient to clean.
[0043] In some embodiments, in combination with Figure 1 and Figure 3 , the first end 101 has a first joint 104, and the air inlet assembly 200 has a second joint 201, and the air inlet assembly 200 is detachably connected to the first end 101 through the first joint 104 and the second joint 201. The detachable connection makes it convenient to install the air inlet assembly 200 on the first pipe 100 when needed, and facilitates the disassembly of the air inlet assembly 200 after use, avoiding the whole first pipe 100 being too large in size and weight to be inconvenient to carry. Further, according to the blockage of the tuyere 50, the air inlet assembly 200 with different air volume or air pressure is selected to improve the versatility of the tuyere 50 cleaning tool 10 of the float glass annealing furnace 1.
[0044] In one of the embodiments, in combination with Figure 1 and Figure 3 , the first joint 104 and the second joint 201 are sealingly connected. The sealing connection can ensure that the air flow provided by the air inlet assembly 200 to the first pipe 100 will not leak out from the connection, so that the tuyere 50 cleaning tool 10 of the float glass annealing furnace 1 can more effectively blow the air flow to the tuyere 50 of the annealing furnace 1, avoiding air pressure loss and air volume loss, and improving the cleaning effect. If there is leakage at the connection, it will cause the air pressure to drop, affecting the strength and speed of the air flow.
[0045] In one of the embodiments, in combination with Figure 1 and Figure 3 , the first joint 104 and the second joint 201 are threadedly connected. Threaded connection realizes tight connection through rotation, with high connection strength, stability and air tightness. This connection mode can withstand greater pressure and tension, ensuring that the tuyere 50 cleaning tool 10 of the float glass annealing furnace 1 will not fail due to loose connection during use, and the connection and disassembly can be realized by rotation, which is simple and convenient to operate. The clamping connection is realized by the elastic action of buckles or clamping springs, without the need for complex operations such as rotation or tightening, which makes the clamping connection more simple and convenient to install and disassemble, improving work efficiency.
[0046] In one of the embodiments, in combination with Figure 1 and Figure 3 , the first joint 104 and the second joint 201 are clamped, and the clamping is realized by the elastic action of buckles or clamping springs to achieve tight connection, which can effectively prevent air flow leakage. The clamping does not need to use threads or other complex connection structures, reducing manufacturing and processing costs. At the same time, since the clamping is easy to disassemble and replace, the maintenance and use costs are also reduced.
[0047] In some embodiments, in combination with Figure 3The air inlet assembly 200 includes a compressor 210, which is used to pressurize and / or accelerate the airflow within the air duct 103. The compressor 210 pressurizes the airflow within the air duct 103, giving it higher pressure, which helps in high-pressure cleaning of the nozzles 50 of the annealing furnace 1. This ensures that the airflow can penetrate deep into the nozzles 50 to remove accumulated ash, debris, etc., improving cleaning efficiency and enhancing the cleaning effect.
[0048] Specifically, the power of the compressor 210 is 5000W-10000W. A 5000W-10000W compressor 210 can generate a stronger airflow, which can more effectively flush and remove impurities from the nozzle 50, improving cleaning efficiency. By increasing the intensity and speed of the airflow, the compressor 210 can more thoroughly clean the nozzle 50, reduce residue, and ensure unobstructed flow, thereby improving the working efficiency of the annealing furnace 1.
[0049] Specifically, the air flow rate of the compressor 210 is 400 m³ / s. 3 / h-600m 3 / h. 400m 3 / h-600m 3 An airflow rate of / h can deliver a large amount of airflow to the nozzle 50 in a shorter time, thereby quickly cleaning the dirt and dust inside the nozzle 50 and improving cleaning efficiency. Meanwhile, 400m 3 / h-600m 3 An airflow rate of / h also helps ensure that the airflow can evenly cover all parts of the nozzle 50, improving the uniformity and quality of cleaning.
[0050] In one embodiment, combined with Figure 3 A switching valve 105 is installed inside the first end 101 to control the opening and closing of the air duct 103. The opening degree of the switching valve 105 controls the flow rate of the air duct 103, thereby ensuring that the airflow can be blown towards the air nozzle 50 of the annealing furnace 1 at a predetermined intensity and speed. By adjusting the opening degree of the switching valve 105, different cleaning needs can be flexibly adapted to ensure the consistency and stability of the cleaning effect. For example, by reducing the opening degree, the flow rate and air pressure are increased, which is beneficial for cleaning the heavily clogged air nozzle 50; by increasing the opening degree, the flow rate and air pressure are reduced, which increases the cleaning area and cleaning efficiency. In this way, precise airflow control helps to ensure that the airflow can more effectively flush and remove dirt and ash from the air nozzle 50. By adjusting the opening degree of the switching valve 105, the distribution and intensity of the airflow can be optimized, thereby improving the thoroughness and quality of cleaning.
[0051] In some embodiments, combined with Figure 1 and Figure 4, the air outlet assembly 300 has an equalizing chamber 302, and the air outlet holes 301 are in communication with the equalizing chamber 302. The design of the equalizing chamber 302 enables the airflow to form a relatively uniform pressure distribution in the chamber before flowing out of the air outlet holes 301, thereby achieving equalized air outlet. The uniform pressure and velocity enable the airflow to cover the target area more uniformly, thereby improving the air outlet effect.
[0052] In some embodiments, in combination Figure 1 and Figure 4 , the air outlet assembly 300 is welded to the second end portion 102, ensuring that a firm and stable connection is formed between the air outlet assembly 300 and the second end portion 102. The welded connection has excellent sealing performance. During the welding process, the metal melts and re-solidifies, filling any tiny gaps at the connection, thereby forming a tight and seamless connection, which helps to prevent airflow leakage at the connection and ensures that the air outlet assembly 300 can more effectively deliver airflow to the target area.
[0053] In one embodiment, the number of air outlet holes 301 is multiple. Multiple air outlet holes 301 can simultaneously deliver airflow to multiple nozzles 50, thereby significantly shortening the cleaning time. Multiple air outlet holes 301 can ensure that the airflow is more uniformly distributed to each nozzle 50, thereby enhancing the cleaning effect.
[0054] In one embodiment, in combination Figure 1 , the multiple air outlet holes 301 are used to correspond one-to-one with the multiple nozzles 50. The one-to-one design enables the cleaning process to be carried out in parallel, i.e., multiple nozzles 50 can be cleaned simultaneously. This greatly shortens the cleaning time and improves work efficiency.
[0055] In some embodiments, in combination Figure 5 and Figure 6 , the number of first pipe fittings 100 is at least two, and all the first pipe fittings 100 are arranged side by side. The side-by-side arrangement of the first pipe fittings 100 enables the cleaning tool 10 to simultaneously clean two or more rows of nozzles 50, further improving the cleaning efficiency.
[0056] The float glass annealing lehr 1 nozzle 50 cleaning tool 10 further comprises a reinforcing rod 400, and the reinforcing rod 400 is connected with all the first pipe fittings 100. The reinforcing rod 400 is connected with all the first pipe fittings 100, forming a stable frame structure. The design of the reinforcing rod 400 helps to disperse and withstand the stress and pressure generated during the cleaning process, improving the overall reliability and stability.
[0057] Specifically, the reinforcing rod 400 is welded to the first pipe fitting 100, and the structural strength of the entire cleaning tool 10 is significantly improved, which can better withstand various stresses and pressures during the cleaning process.
[0058] In one of the embodiments, in combinationFigure 5 and Figure 6 The float glass annealing furnace air nozzle 50 cleaning tool 10 further comprises a positioning rod 500 connected to the end of the reinforcing rod 400. The design of the positioning rod 500 makes it easier to achieve accurate positioning during use, ensuring the stability of the position of the air outlet hole 301 and the stability and controllability of the cleaning effect. By adjusting the position and angle of the positioning rod 500, the accurate fit between the cleaning tool 10 and the annealing furnace 1 air nozzle 50 is ensured, thereby avoiding errors and deviations during installation.
[0059] In one embodiment, in combination with Figure 5 and Figure 6 The positioning rod 500 extends away from the first end 101. Specifically, the end of the positioning rod 500 has a positioning head 510 for embedding in the annealing furnace 1. The operator can ensure that the positioning head 510 is closely embedded in the corresponding part of the annealing furnace 1, thereby achieving accurate positioning and helping to ensure the correct alignment between the air outlet hole 301 and the annealing furnace 1 air nozzle 50, improving the cleaning effect. After the positioning head 510 is embedded in the annealing furnace 1, a stable support point can be provided, which helps to enhance the stability of the float glass annealing furnace 1 air nozzle 50 cleaning tool 10 in the annealing furnace 1, preventing displacement due to vibration or impact during cleaning. The stable support point also helps to maintain close contact between the float glass annealing furnace 1 air nozzle 50 cleaning tool 10 and the air nozzle 50, ensuring that the airflow can be uniformly delivered to each air nozzle 50.
[0060] In one embodiment, in combination with Figure 5 and Figure 6 The first pipe 100 is rotatably mounted on the reinforcing rod 400. The operator can adjust the angle and position of the first pipe 100 according to actual needs, more effectively rotating the air outlet hole 301 to contact the annealing furnace 1 air nozzle 50, thereby improving the cleaning effect. The rotatable first pipe 100 allows the cleaning tool 10 to adapt to different sizes and shapes of the annealing furnace 1 air nozzle 50.
[0061] In one embodiment, in combination with Figure 5 and Figure 6 The first pipe 100 is telescopically vertically inserted into the reinforcing rod 400. The operator can easily adjust the length of the first pipe 100 inserted into the annealing furnace 1 according to the specific depth of the annealing furnace 1 air nozzle 50, ensuring that the air outlet can accurately align with the air nozzle 50, improving the accuracy and efficiency of cleaning.
[0062] It should be noted that the telescopic mentioned herein can be that the first pipe 100 itself is telescopic, or the length of the first pipe 100 is not adjustable but can move telescopically relative to the reinforcing rod 400.
[0063] In one embodiment, the first pipe 100 is provided with a cleaning wire 200. Figure 5 and Figure 6 The outlet hole 301 is provided with a rubber sleeve 303, so that the outlet hole 301 can closely fit the tuyere 50, effectively preventing air leakage at the orifice, improving cleaning efficiency and accuracy.
[0064] Specifically, the end opening of the rubber sleeve 303 is larger than the orifice of the outlet hole 301, which can adapt to tuyeres 50 of different diameters. The rubber sleeve 303 can flexibly wrap the tuyere 50.
[0065] Specifically, the rubber sleeve 303 is detachably mounted at the orifice of the outlet hole 301, facilitating replacement.
[0066] In one embodiment, the first pipe 100 is provided with a cleaning wire 200. Figure 5 and Figure 6 The orifice of the outlet hole 301 is provided with a cleaning wire. The cleaning wire can directly contact the impurities such as dust, broken glass, etc. around the tuyere 50 of the annealing furnace 1, and through physical friction, the cleaning wire can easily remove these impurities from the tuyere 50, ensuring the smoothness of the tuyere 50.
[0067] Specifically, the cleaning wire is detachably mounted at the orifice of the outlet hole 301, facilitating replacement.
[0068] In the above embodiments, the materials of the first pipe 100, the air outlet assembly 300, the reinforcing rod 400 and the positioning rod 500 are all stainless steel. Stainless steel has excellent corrosion resistance and can resist various corrosive substances that may exist in the environment of the annealing furnace 1, such as high-temperature gas, molten glass slag, etc.
[0069] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
