Description

Technical Field

[0001] The invention relates to the technical field of annealing technology, and in particular to a glass cold breaking system. Background Art

[0002] If defective glass is disposed of in the annealing stage, the glass production efficiency and quality can be improved. The present invention provides an effective solution to this problem.

[0003] As an important building and industrial material, the production process of glass involves multiple links, among which the annealing process in the annealing kiln is a crucial step. Its main purpose is to control the temperature field and slowly cool the glass to eliminate internal stress, thereby improving the mechanical properties and stability of the glass. Specifically, the annealing process usually includes the following stages: first, the glass is heated to a certain temperature to make it soft enough; then it is kept at this temperature for a period of time to achieve uniform stress release; finally, the temperature is slowly lowered to avoid the generation of new stress caused by too fast cooling. Although this process is complicated, it is crucial to ensure the overall quality of glass products.

[0004] However, in actual production, it is inevitable that some defective glass products will appear inside the annealing furnace. If these defective glass can be processed in the annealing stage, the subsequent cold end board dropping, cutting, crushing and other operations can be avoided, which will significantly improve the efficiency of subsequent operations, reduce resource waste, and improve the quality of the final product. Therefore, how to deal with defective glass in the annealing stage has become a technical problem that needs to be solved urgently. Summary of the invention

[0013] An axial flow fan is arranged on one end of the exhaust duct away from the guide hood, and is used to discharge the water vapor generated by spraying the water mist on the glass plate to the outside of the glass factory through the exhaust duct.

[0023] Figure 2 The figure is a side view of a glass cold breaking system in a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0024] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also fall within the scope of the present invention as long as they conform to the gist of the present invention.

[0025] In a preferred embodiment of the present invention, based on the above problems existing in the prior art, a glass cold breaking system is provided. Figure 1 and Figure 2 As shown, including:

[0026] The water pipeline 1 is erected above the annealing furnace E zone 2 across the width of the annealing furnace plate;

[0027] A plurality of sprayers 3 are arranged on the water pipeline 1 and located above the conveying roller 4 of the annealing furnace E zone 2, and are used to spray water mist on the defective glass plates conveyed on the conveying roller 4 to achieve cold crushing of the glass plates in the annealing furnace E zone 2.

[0028] Specifically, in this embodiment, water supply points can be set on both sides of the annealing furnace E zone 2, and water can be supplied to the water pipeline 1 through the water supply points. Figure 1 As shown, water can flow into both ends of the water pipe 1. Through the water pipe 1 across the width of the annealing furnace plate, water mist is sprayed on the glass plate, so that the high-temperature glass plate breaks when it encounters water, achieving the purpose of cold breaking the glass plate.

[0029] Further preferably, a corresponding identification device can be provided at the front end of the annealing furnace E zone to identify the defective glass plate, and then control the sprayer 3 to spray based on the identification result, wherein the sprayer 3 can preferably control the spray atomization to different degrees. The above-mentioned identification device includes but is not limited to a visual identification device. Each sprayer 3 can preferably be controlled to open and close synchronously, or independently, which is not limited here.

[0030] In a preferred embodiment of the present invention, a ball valve 5 is provided on the water pipeline 1 for adjusting the spraying water volume of the water mist.

[0031] In a preferred embodiment of the present invention, a collecting bin 6 is provided at the bottom of the annealing furnace E zone 2. The collecting bin 6 is located below the conveying roller 4 and is used to collect broken glass plates.

[0032] In a preferred embodiment of the present invention, a steam extraction device is also included, including:

[0033] The drainage cover 7 is arranged above the water pipe 1, and an air extraction hole is opened on the drainage cover 7;

[0034] An exhaust pipe 8, one end of which is connected to the drainage cover 7 and communicated with the exhaust hole, and the other end of which extends to the outside of the glass factory;

[0035] The axial flow fan 9 is arranged on one end of the exhaust duct 8 away from the drainage hood 7, and is used to discharge the water vapor generated by spraying the water mist on the glass plate to the outside of the glass factory through the exhaust duct 8.

[0036] Specifically, since water vapor is generated when the water pipe 1 is sprayed on the glass plate, if it is not discharged in time, on the one hand, moisture will accumulate in the factory, thereby affecting the production environment, and on the other hand, excessive humidity will increase the risk of corrosion of equipment and production facilities. Water vapor may also react with other chemical substances to produce unsafe gases or affect the stability of the production process and the quality of the finished product. Based on this, in this embodiment, a steam extraction device is provided to discharge the water vapor generated by the cold broken glass plate to the outside of the factory, which can ensure the dryness and stability of the glass production environment, thereby improving production efficiency and product quality.

[0037] The axial flow fan 9 can provide power for draining away the water vapor.

[0038] In a preferred embodiment of the present invention, a manual butterfly valve 10 is further provided on the exhaust pipeline 8 for adjusting the exhaust flow rate of the exhaust pipeline 8 .

[0039] In a preferred embodiment of the present invention, a steel mesh 11 is provided at one end of the exhaust pipe 8 extending to the outside of the glass factory.

[0040] In a preferred embodiment of the present invention, a bracket 12 is further included, which is erected above the water pipe 1 , and the drainage cover 7 is installed on the bracket 12 .

[0041] In a preferred embodiment of the present invention, an operating table is further included, including a maintenance platform 13, which is arranged near the axial flow fan 9 and the manual butterfly valve 10. A fence 14 is arranged around the maintenance platform 13, and the bottom of the maintenance platform 13 is connected to the ground through a cage ladder 15.

[0042] Specifically, in this embodiment, since the exhaust pipe 8 for draining water vapor runs at a higher level, an operating table is provided to facilitate the inspection and operation of the axial flow fan and the manual butterfly valve.

[0043] In summary, the sprayers installed on the water pipes in the E zone of the annealing furnace spray water mist onto the high-temperature glass plates in the E zone of the annealing furnace, causing the glass to break cold and then be collected in the collection bin at the bottom of the E zone of the annealing furnace. At the same time, the axial flow fan is operated to exhaust the water vapor generated when the glass is broken cold to the outside of the factory through the steam extraction device on the E zone of the annealing furnace. The defective glass plates on the conveying rollers in the E zone of the annealing furnace are broken cold, effectively avoiding the operations of falling plates, cutting, and breaking at the cold end, and improving the efficiency and quality of glass production; at the same time, the water vapor generated when the glass is broken cold can be exhausted to the outside of the glass factory, ensuring the dryness and stability of the glass production environment, thereby improving production efficiency and product quality.

[0044] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
