Description

Technical Field

[0001] The invention relates to the technical field of glass kilns, and in particular to a pre-tightening device and a masonry method for masonry of a kiln arch. Background Art

[0002] Liquid crystal substrate glass is a thin glass sheet produced by the overflow method with an extremely flat surface. Liquid crystal substrate glass is mainly used in the field of liquid crystal display and is a key component of liquid crystal display devices. With the continuous development of liquid crystal display technology, the application field of liquid crystal substrate glass is also expanding, such as smart phones, tablet computers, laptops, LCD TVs, etc.

[0003] The liquid crystal substrate glass kiln is the core equipment for glass substrate production, and its structure and function are crucial to the manufacture of liquid crystal glass. Liquid crystal substrate glass kilns are usually composed of multiple systems, including furnace body, combustion system, heating system, exhaust system, cooling system, control system and feeding system. These systems work together to ensure that the kiln can operate stably and efficiently. The working principle of the liquid crystal substrate glass kiln is to add raw glass into the kiln and heat it to a molten state through the heat energy provided by the combustion system. Inside the kiln, the glass liquid is subjected to different temperature fields and produces local flow, ensuring that it is evenly heated and flows. At the same time, the control system monitors and controls the parameters of the kiln such as temperature, furnace pressure, liquid level and bubble boundary in real time to ensure the quality and stability of the glass liquid.

[0004] The arch is a key part of the brick structure of the liquid crystal substrate glass kiln, generally referring to the upper arch structure of the melting furnace flame space. The arch of the melting part and the breast wall form the combustion space of the flame above the molten glass liquid surface. The arch plays the role of sealing upwards, and at the same time reflects the energy of flame radiation to radiate heat transfer to the batch and glass liquid.

[0005] At present, the quality control of the large crown masonry in the liquid crystal substrate glass kiln is greatly influenced by the masonry workers. Due to the different strengths of different workers, even the strengths of the same worker vary, resulting in uneven quality of masonry. The arc transition of the large crown is often not smooth, and the local surface is undulating, which seriously affects the safety of the kiln crown, and thus affects the safety of kiln production. Summary of the invention

[0006] In view of the problem of poor transition smoothness of the arc surface of the large arch masonry in the prior art, the present invention provides a pre-tightening force device and a masonry method for the large arch masonry of a kiln.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention provides a pre-tightening device for kiln arch masonry, comprising a bracket, a pre-tightening force applying mechanism and a control system, wherein the bracket spans across both sides of the kiln side wall and can move along the walkways on both sides of the kiln; the pre-tightening force applying mechanism is arranged on the bracket and can move laterally along the bracket, and is used to provide pre-tightening force for refractory bricks so that the installation tightness thereof is consistent with that of other refractory bricks; the control system is electrically connected or communicatively connected to the pre-tightening force applying mechanism, and is used to control the pre-tightening force applying mechanism.

[0014] Optionally, reinforcing ribs are provided between the column foot and the platform.

[0015] Optionally, a roller is provided at the bottom of the bracket.

[0016] The present invention provides a method for masonry of a kiln arch using the above-mentioned pre-tightening device, comprising: Install the arch mortar and adjust the height and levelness of the arch mortar according to the position of the large arch to be built; Place refractory bricks on both sides of the adjusted arch frame, and draw lines on the arch frame surface with the refractory bricks on both sides of the arch frame as endpoints; Masonry is carried out along the marked direction. During the masonry process, the position of the preload force applying mechanism on the bracket is controlled so that the preload force applying mechanism is close to the surface of the refractory bricks to apply a specific preload force to the refractory bricks, so that the installation size and tightness of each refractory brick remain consistent until the masonry of all refractory bricks is completed.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a pre-tightening device for the masonry of a kiln arch, comprising a bracket, a pre-tightening force applying mechanism and a control system. The bracket spans across the two sides of the kiln side wall and can move along the walkways on both sides of the kiln; the pre-tightening force applying mechanism is arranged on the bracket and can move laterally along the bracket to provide pre-tightening force for refractory bricks so that the installation tightness of the bricks is consistent with that of the other refractory bricks; the control system is electrically connected or communicatively connected to the pre-tightening force applying mechanism to control the pre-tightening force applying mechanism. Through the setting of the preload mechanism, each refractory brick can be accurately provided with a balanced preload force to ensure the consistency of the masonry quality, strengthen the connection strength between the refractory bricks, and make the overall structure more stable, thereby ensuring a smooth transition of the large arc and further ensuring the safety of the kiln; the bracket spans across both sides of the kiln side wall and can move along the walkways on both sides of the kiln to ensure that the preload mechanism can reach any position of the refractory bricks, which is convenient for construction; through the setting of the control system, the intelligent control of the refractory brick masonry force can be achieved, without relying on manpower to control the quality of the refractory brick masonry, reducing the impact of refractory bricks on the quality by relying solely on manpower, making construction simpler and easier, and at the same time, improving construction efficiency and precision, and indirectly reducing the additional costs caused by rework or repair.

[0018] The preload force applying mechanism includes a telescopic part arranged on the top of the bracket, and the telescopic part can move laterally along the bracket to ensure that the preload force can be evenly applied to various positions of the kiln arch, which not only improves the construction accuracy, but also makes the adjustment of the preload force more flexible and convenient; a sleeve is arranged at the end of the telescopic part, a spring is arranged in the sleeve, a pressure block is connected to the end of the spring, a vibrator is arranged on the pressure block, and the vibrator and the telescopic part are both electrically connected or communicatively connected to the control system. The spring, as an elastic element, can provide an adjustable preload force according to the actual needs of the kiln arch. By adjusting the compression amount of the spring, the pressure applied by the pressure block to the refractory brick can be accurately controlled to ensure that the tightness between the refractory bricks remains consistent. The vibrator on the pressure block can generate tiny vibrations under the action of the control system. These vibrations help to eliminate the tiny gaps between the refractory bricks, make the refractory bricks fit together more closely, promote the combination of the refractory bricks and the refractory mud, and further improve the overall stability and consistency of the structure. At the same time, the inconsistency of manual knocking and the insecurity of operation are reduced.

[0019] A push rod is arranged between the pressing block and the spring, and the push rod can move in the sleeve along the direction of the spring elastic force. The setting of the push rod realizes the effective connection between the pressing block and the spring. At the same time, the pre-tightening force applied by the pressing block to the refractory bricks can be further fine-tuned, so that the application of the pre-tightening force is more precise, which can meet the specific requirements of different kiln arch masonry for pre-tightening force and has better stability.

[0020] The end of the push rod is hinged to the pressing block, making the connection between the push rod and the pressing block more flexible. This flexibility allows the pressing block to make slight adjustments according to the actual shape and size of the kiln arch during the application of preload, so as to better adapt to different construction angles, ensure that the pressure can be more evenly transmitted to the surface of the refractory bricks, and reduce the damage or loosening of the refractory bricks caused by uneven pressure distribution.

[0021] The pressing block includes a first pressing part and a second pressing part, the first pressing part is connected to the second pressing part, and the first pressing part and the second pressing part respectively press two adjacent surfaces of the refractory brick; vibrators are respectively arranged on the outer sides of the first pressing part and the second pressing part. The first pressing part and the second pressing part respectively press two adjacent surfaces of the refractory brick, ensuring that the refractory brick is subjected to uniform pre-tightening force in multiple directions. This design helps to eliminate the tiny gaps between refractory bricks and enhance the tight connection between refractory bricks, thereby improving the overall stability and durability of the kiln arch. At the same time, the application of pre-tightening force is precisely controlled by controlling the vibrator to ensure that the pre-tightening force can be accurately transmitted to the refractory brick to avoid over-tightening or under-tightening.

[0022] The bracket includes a horizontal platform and a plurality of vertical column feet, the platform includes guide parts and limit parts respectively arranged on both sides of the preload applying mechanism, a guide plate is arranged between the guide part and the limit part, the guide plate is fixedly connected to the preload applying mechanism, and the guide plate can move between the guide part and the limit part. The horizontal platform of the bracket provides a stable working foundation for the preload applying mechanism. The presence of the platform enables the mechanism to maintain better stability when applying the preload, avoiding uneven application or failure due to shaking or tilting. The setting of the guide part and the limit part, in conjunction with the movable guide plate, ensures that the preload applying mechanism can move along a predetermined path during the movement and adjustment process, thereby improving the accuracy of application.

[0023] The guide plate is connected to the preload force applying mechanism via a mounting flange, and the mounting flange is connected to the guide plate via a fastening bolt. The flange connection itself has high strength and rigidity and can withstand large pressure and tension. Connecting the guide plate to the preload force applying mechanism via the mounting flange can ensure that the connection between the two is stable and reliable and is not prone to loosening or falling off.

[0024] A reinforcing rib is arranged between the column foot and the platform. The arrangement of the reinforcing rib can significantly improve the bearing capacity between the column foot and the platform. When subjected to external force, the reinforcing rib can effectively disperse and transfer the load, making the entire structure more stable.

[0025] The bottom of the bracket is provided with rollers to facilitate the movement of the bracket on the aisle.

[0026] The present invention provides a method for laying the kiln crown using the above-mentioned preload device. The method installs the crown and adjusts the crown height and levelness according to the position of the crown to be laid. Then, refractory bricks are laid on both sides of the adjusted crown, and the crown surface is marked with the refractory bricks on both sides of the crown as endpoints. Finally, refractory bricks are laid along the marked direction with the assistance of the preload device to achieve the laying of the kiln crown. The method is simple and easy to operate. The quality of the kiln crown is better, there is no large local surface fluctuation, the stability and durability are better, and the downtime and maintenance costs caused by structural problems are reduced. It provides a more reliable and efficient solution for engineering construction in related fields. BRIEF DESCRIPTION OF THE DRAWINGS
