Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass bottle manufacturing equipment technology, and in particular to a glass bottle heating furnace. Background Technology
[0002] A glass bottle is a bottle-shaped container made of glass, an amorphous inorganic non-metallic material mainly composed of silicon dioxide. In daily life, glass bottles have a wide range of applications, such as for holding beverages like beer and juice; they are also commonly used for pharmaceutical packaging, holding oral liquids and medicines; they are used for cosmetic packaging, such as perfume and lotion bottles; and they are also used as condiment bottles, holding soy sauce, vinegar, etc. The functions and benefits of glass bottles are significant. They are chemically stable, effectively protecting the contents and preventing them from reacting with external substances and deteriorating; they have good sealing properties, effectively preventing evaporation and leakage; their transparency allows for easy observation of the contents; moreover, glass bottles are reusable, environmentally friendly, and economical, and their attractive appearance also has a certain decorative appeal.
[0003] Glass bottle manufacturing mainly involves two methods: pressing and blowing. The pressing method involves melting raw glass into molten glass, placing it into a mold, pressing it into shape using a press, annealing to relieve stress, and finally performing surface treatment and other post-processing. The blowing method involves melting raw glass into molten glass, dripping it into a mold, and blowing it into shape using compressed air. This method can be done manually or by machine. After forming, it also requires annealing, bottle neck trimming, cleaning, and other post-processing steps to ensure the quality of the glass bottle.
[0004] In the prior art, glass bottle processing often involves annealing, which can eliminate thermal stress and improve the strength and stability of the glass bottle. However, after long-term use, glass fragments, dirt and other impurities will remain on the surface of the heat-conducting plate used for annealing. This will affect the thermal conductivity of the heat-conducting plate and cause uneven local heat distribution in the glass bottle, resulting in defects such as bubbles and deformation. Therefore, a glass bottle heating furnace is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a glass bottle heating furnace, comprising a furnace body 1. The furnace body 1 serves as the main structure of the entire heating furnace and is made of high-temperature resistant and corrosion-resistant high-grade refractory bricks and heat-resistant alloy steel. The furnace body 1 is generally a closed box structure, which can provide a stable space for the heating process of glass bottles to accommodate a certain amount of glass bottles or glass raw materials. A cleaning mechanism is slidably connected to the inner side of the furnace body 1, and a coordinated temperature control annealing mechanism is fixedly connected to the inner side of the furnace body 1.
[0034] A bidirectional threaded rod 7 is rotatably connected to the inner side of the furnace body 1, and a drive assembly is fixedly connected to the outer side of the furnace body 1. A threaded slider 8 is threadedly connected to the outer side of the bidirectional threaded rod 7. When the bidirectional threaded rod 7 rotates, the threaded slider 8 will move linearly along the axial direction of the threaded rod on its outer side, and drive the subsequent components to extend or shorten. A rotating shaft is fixedly connected to the outer side of the threaded slider 8. A cleaning connecting rod 9 is rotatably connected to the outer side of the rotating shaft of the threaded slider 8. A second cleaning connecting rod 10 is rotatably connected to the outer side of the rotating shaft of the threaded slider 8. A connecting shaft 11 is fixedly connected to the middle section of the first cleaning connecting rod 9. The outer side of the connecting shaft 11 is rotatably connected to the inner side of the first cleaning connecting rod 9. The middle sections of the first cleaning connecting rod 9 and the second cleaning connecting rod 10 are rotatably connected to each other through the connecting shaft 11. This connection method allows the two connecting rods to cooperate with each other during movement, realize the extension or shortening in the direction of movement, drive the subsequent components to reciprocate, and thus clean the glass fragments or dirt remaining on the heat-conducting plate 5.
[0035] The drive assembly includes a cleaning motor 6, which provides power to the entire cleaning mechanism. The rotation of the motor drives the bidirectional threaded rod 7 to rotate. The outer side of the cleaning motor 6 is fixedly connected to the outer side of the furnace body 1, and the outer side of the output end of the cleaning motor 6 is fixedly connected to the outer side of the bidirectional threaded rod 7.
[0036] A rotating shaft is fixedly connected to the end of cleaning link 19 away from the threaded slider 8, and a rotating shaft is fixedly connected to the end of cleaning link 20 away from the threaded slider 8. A sliding push block 12 is rotatably connected to the outside of the rotating shafts of cleaning link 19 and cleaning link 20. When the threaded slider 8 drives the cleaning link to move, the sliding push block 12 will perform lateral opening and closing movements under the drive of the cleaning link, thereby pushing the subsequent parts to perform reciprocating cleaning movements.
[0037] A cleaning groove 15 is provided on the inner side of the furnace body 1. A cleaning scraper 14 is slidably connected to the inner side of the cleaning groove 15. An I-shaped groove 13 is provided on the inner side of the cleaning scraper 14. The inner side of the I-shaped groove 13 is slidably connected to the outer side of the sliding push block 12. When the sliding push block 12 moves, it will drive the cleaning scraper 14 to slide in the cleaning groove 15. The bottom of the cleaning scraper 14 slides in contact with the top of the heat-conducting plate 5, thereby cleaning the surface of the heat-conducting plate 5 and removing residual glass shards and other impurities.
[0038] A heat-conducting plate 5 is fixedly connected to the bottom inner side of the furnace body 1, and a heating rod 22 is fixedly connected to the inner side of the heat-conducting plate 5. The bottom of the cleaning scraper 14 is slidably connected to the top of the heat-conducting plate 5. The heat generated by the heating rod 22 is first transferred to the heat-conducting plate 5. The heat-conducting plate 5, with its good thermal conductivity, evenly distributes the heat to a large area of the bottom inner side of the furnace body 1. In this way, the glass bottle or glass raw material placed on the heat-conducting plate 5 can obtain relatively uniform heat from the bottom, avoiding uneven heating caused by excessively high or low local heat, which helps to improve the heating quality of the glass bottle and reduce defects such as bubbles and deformation caused by uneven heating.
[0039] Reference Figures 1 to 3 The coordinated temperature-controlled annealing mechanism includes a direct-injection burner 17. The direct-injection burner 17 provides a large amount of heat to the furnace by injecting and burning fuel, and is one of the main heat sources in the heating process. The temperature control of the direct-injection burner 17 is relatively complex and has large temperature fluctuations, but its flame temperature is high, which can quickly release heat and raise the temperature. It can make the workpiece reach a high temperature in a short time, providing a large amount of heat for the annealing process quickly. The direct-injection burner 17 is uniformly fixed inside the furnace body 1. The uniform distribution of the direct-injection burner 17 can make the temperature inside the furnace rise more evenly. Electric heating wires 16 are uniformly fixed inside the furnace body 1. The heating speed of the electric heating wires 16 is relatively slow and requires a long time to reach the predetermined temperature. However, the electric heating wires 16 heater has precise annealing temperature control, relatively stable heat transfer, and simple and convenient operation. The annealing process can be precisely controlled by an automated control system. Multiple through holes are opened on the outer wall of the furnace body 1. A guide fan 18 is fixedly connected to the inside of the through holes of the furnace body 1. The guide fan 18 can realize the circulation of air inside the furnace and the uniform distribution of temperature.
[0040] An air inlet pipe 2 is fixedly connected to the outside of the furnace body 1. The air inlet pipe 2 is used to supply air or other gases required for combustion into the furnace to ensure the normal combustion of the direct injection burner 17 and meet the requirements of the furnace process environment. A waste treatment box 3 is fixedly connected to the side of the furnace body 1 away from the air inlet pipe 2. The waste treatment box 3 is usually equipped with filtration and purification devices to treat the exhaust gas discharged from the furnace and remove dust, harmful gases and other harmful substances to meet environmental emission standards. An exhaust pipe 4 is fixedly connected to the outside of the waste gas treatment box 3. The exhaust gas purified by the waste gas treatment box 3 is discharged into the external environment through the exhaust pipe 4.
[0041] A hinge 19 is fixedly connected to the bottom of the furnace body 1. The hinge 19 can drive the opening and closing of the heat-insulating furnace door 20. The other end of the hinge 19 is fixedly connected to the heat-insulating furnace door 20. An observation window 21 is provided on the outside of the heat-insulating furnace door 20. The heat-insulating furnace door 20 can effectively prevent the heat inside the furnace from escaping, and the observation window 21 on its outside allows the operator to observe the situation inside the furnace in real time.
[0042] Working principle: In the initial stage of operation, the air or other specific gases necessary for combustion are precisely delivered into the furnace through the air inlet pipe 2 to ensure the smooth progress of subsequent heating processes.
[0043] During the heating process, the direct-injection burner 17 and the heating wire 16 work together. The direct-injection burner 17 injects fuel (such as natural gas or coal gas) with precision, which quickly mixes and burns intensely with the gas supplied to the furnace, releasing a large amount of heat in a very short time. This rapidly increases the furnace temperature, providing strong power support for the rapid heating of the glass bottles and the initial heat requirements of the annealing process. However, while the direct-injection burner 17 provides efficient heating, its temperature control is relatively complex, resulting in some temperature fluctuations. At this point, the heating wire 16 plays an indispensable auxiliary role. Although the heating speed of the heating wire 16 is relatively slow, requiring a longer time to reach the predetermined temperature, it has significant advantages in terms of precise temperature control and stable heat transfer. After the direct-injection burner 17 rapidly increases the furnace temperature, the heating wire 16 can finely adjust and stabilize the temperature. When the furnace temperature fluctuates due to the operation of the direct-injection burner 17, the heating wire 16 can precisely adjust its heating power according to the instructions of the temperature control system, so that the furnace temperature is always kept within the precise range required by the process, providing a stable and precise temperature environment for the heating process of the glass bottle.
[0044] Meanwhile, the air guide fan 18 operates continuously and stably, promoting constant air circulation within the furnace. This ensures that heat is evenly distributed throughout the furnace space, preventing localized overheating or underheating and guaranteeing that the glass bottles or raw materials are heated in a uniform temperature field. The glass bottles or raw materials are properly placed on the heat-conducting plate 5 at the bottom inner side of the furnace body 1. The heat generated by the heating rod 22 is first rapidly transferred to the heat-conducting plate 5. Thanks to its excellent thermal conductivity, the heat-conducting plate 5 evenly diffuses the heat to a large area at the bottom inner side of the furnace body 1. This allows the glass bottles or raw materials placed on it to receive a uniform and stable heat supply from the bottom, effectively avoiding heating defects caused by uneven localized heat, such as bubbles and deformation. This greatly contributes to improving the heating quality of the glass bottles.
[0045] After heating is completed, if the operator needs to observe the situation inside the furnace in real time, they can easily check through the observation window 21 on the outside of the insulated furnace door 20. The insulated furnace door 20 can not only effectively block the loss of heat inside the furnace and reduce energy consumption, but also provide the operator with a safe and intuitive viewing window.
[0046] When a certain amount of glass fragments, dirt, and other impurities accumulate on the surface of the heat-conducting plate 5 and cleaning is required, the operator starts the cleaning motor 6. The cleaning motor 6 then starts running, and its powerful output drives the bidirectional threaded rod 7 to rotate, which in turn causes the threaded slider 8 to move linearly along the axial direction of the bidirectional threaded rod 7. The movement of the threaded slider 8 drives the cleaning connecting rod 1 9 and the cleaning connecting rod 2 10 to move accordingly, causing the sliding push block 12 to open and close laterally. This series of mechanical linkages ultimately causes the cleaning scraper 14 to slide back and forth in the cleaning groove 15, performing a thorough cleaning of the surface of the heat-conducting plate 5 and effectively removing residual glass fragments and other impurities.
[0047] During the entire operation of the heating furnace, the generated exhaust gas first enters the exhaust gas treatment box 3 through a specific channel. The exhaust gas treatment box 3 is carefully equipped with a series of advanced devices such as filters and purifiers, which can efficiently treat harmful substances such as dust and harmful gases in the exhaust gas to meet strict environmental emission standards. After purification, the exhaust gas is safely and compliantly discharged into the external environment through the exhaust pipe 4, ensuring production while fully taking into account environmental protection requirements.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
