Description
Technical Field
[0001] This utility model relates to the field of glass firing technology, and in particular to a high-efficiency combustion device for controlling residual oxygen in glass kilns. Background Technology
[0002] Glass is an amorphous inorganic non-metallic material, generally made from quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash and other main raw materials, with the addition of a small amount of auxiliary raw materials. At present, most glass production is carried out in kilns, that is, glass kilns are used, which mainly refer to the processing equipment used to melt glass batches in glass manufacturing.
[0003] Glass production involves melting and clarifying powdered materials and clinker mixed according to glass composition at high temperatures in a kiln to form molten glass that meets the requirements. During the production process, the raw materials for glass production need to be heated. Currently, heating devices for glassware kilns are mainly used to complete the heating in glass production.
[0004] In traditional glass furnace combustion devices, the air-fuel mixing ratio is often difficult to control precisely during combustion. On the one hand, insufficient air supply leads to incomplete combustion, wasting energy and producing a large amount of incomplete combustion products, affecting glass quality. On the other hand, excessive air supply causes a large amount of heat to be carried away by the excess air, reducing the furnace's thermal efficiency. Furthermore, traditional glass furnace combustion devices are not environmentally friendly. Glass firing produces large amounts of harmful gases, such as nitrogen oxides (NOx) and sulfur dioxide (SO2). The emission of these pollutants not only causes serious environmental pollution but may also lead to acid rain and other environmental problems. Therefore, this paper proposes a high-efficiency combustion device for residual oxygen control in glass furnaces to address these issues. Utility Model Content

[0031] 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.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a high-efficiency combustion device for controlling residual oxygen in a glass kiln, comprising a base 1 and a fixing plate 20. A combustion chamber 2 is fixedly connected to the top of the base 1, serving as the core space for fuel combustion. Two residual oxygen cylinders 3 are fixedly connected to the left side of the top of the base 1, storing fuel and oxygen to provide necessary raw materials for the combustion process. A gas pump 4 is installed outside the residual oxygen cylinders 3, with a connecting pipe 6 fixedly connected to the drive end of the gas pump 4. A flow valve 5 is installed on the side of the connecting pipe 6 near the gas pump 4. The gas pump 4 serves as a power source, delivering the fuel and oxygen from the residual oxygen cylinders 3 to the flow valve 5 through the connecting pipe 6. The flow valve 5 precisely controls the flow rate of fuel and oxygen output from the residual oxygen cylinders 3, based on combustion requirements and actual operating conditions.
[0033] A mixing pipe 7 is fixedly connected to the adjacent side of the two connecting pipes 6. The connecting pipes 6 form a gas transport channel, ensuring that fuel and oxygen can be smoothly transferred from the fuel and oxygen cylinder 3 to the mixing pipe 7. Multiple baffles 1 and 2 are fixedly connected inside the mixing pipe 7, which thoroughly mix the fuel and oxygen input from the flow valve 5. The mixing pipe 7 uses the internal baffles 1 and 2 to split and remix the airflow, ensuring uniform mixing of fuel and oxygen. This provides a guarantee for complete combustion in the combustion chamber 2 and is an important component for improving combustion efficiency. An air intake pipe 10 is fixedly connected to the bottom end of the mixing pipe 7 near the combustion chamber 2. The air intake pipe 10 transports the fully mixed fuel and oxygen from the mixing pipe 7 to the combustion chamber 2, providing raw materials for the combustion process and ensuring that the mixed gas can smoothly enter the combustion chamber 2 to cooperate with the combustion components inside the combustion chamber 2 to achieve fuel combustion and heat generation.
[0034] refer to Figure 2 The combustion chamber 2 is equipped with a combustion assembly, which includes a first insulation plate 11. The first insulation plate 11 is fixedly connected to the outside of the combustion chamber 2. A second insulation plate 12 is fixedly connected to the top of the first insulation plate 11. The outside of the air intake pipe 10 passes through the left side of the combustion chamber 2 and is fixedly connected to the left side of the second insulation plate 12. The first insulation plate 11 and the second insulation plate 12 work together to further enhance the insulation effect of the combustion chamber 2, and at the same time provide a position for the installation and fixing of the air intake pipe 10 and the air outlet pipe 18, ensuring the stability and sealing of the pipes.
[0035] The combustion chamber 2 has a fixedly connected melting chamber 13 inside, which is used to hold the materials that need to be heated. Two heating chambers 14 are fixedly connected to the top of the combustion chamber 2. These heating chambers 14 work in conjunction with the combustion chamber 2 to enhance the heating effect on the materials. The heat generated by fuel combustion in the combustion chamber 2 is further transferred to the materials in the melting chamber 13 through the heating chambers 14, improving heating efficiency and uniformity, and ensuring that the materials can be fully melted. A cover plate 15 is detachably connected to the top of the combustion chamber 2. The cover plate 15 covers the top of the combustion chamber 2, sealing it and preventing heat loss and gas leakage.
[0036] A pressure pump 16 is fixedly connected to the base 1. A pressure pipe 17 is installed at the top of the pressure pump 16, and the top of the pressure pipe 17 is fixedly connected to the inside of the cover plate 15. The pressure pump 16 inputs air pressure into the combustion chamber 2 through the pressure pipe 17, and adjusts the air pressure in the combustion chamber 2 to achieve stable heating of the internal fuel, improve combustion efficiency and heating effect, and ensure stable operating conditions in the glass furnace. An exhaust pipe 18 is fixedly connected to the middle of the side of the combustion chamber 2 away from the fuel oxygen cylinder 3. The exhaust pipe 18 is fixedly connected to the middle of the right side of the second insulation plate 12. The exhaust pipe 18 is a device for venting harmful gases generated after the fuel combustion in the combustion chamber 2.
[0037] refer to Figure 3 , Figure 4 The fixed plate 20 engages with the top of the exhaust pipe 18. Two slots 19 are provided at the top of the exhaust pipe 18. Three activated carbon plates 21 are fixedly connected to the bottom of the fixed plate 20. The activated carbon plates 21 utilize the adsorption properties of activated carbon to adsorb and filter harmful substances in the combustion gases, removing odors, organic pollutants, etc., thus purifying the discharged gases and reducing environmental pollution. A filter bag 22 is fixedly connected to the bottom of the fixed plate 20, further filtering solid particles and fine impurities in the harmful gases.
[0038] Positioning cylinders 23 are fixedly connected to both sides of the fixing plate 20. The outer side of the limiting plate 25 is slidably connected to the inner wall of the positioning cylinder 23, and the positioning cylinder 23 provides sliding guidance for the fixing rod 24. The fixing rod 24, made of metal, is slidably connected inside the positioning cylinder 23. The limiting plate 25 is fixedly connected to the middle of the fixing rod 24. The limiting plate 25 is installed on the fixing rod 24 and cooperates with the spring 26 to limit the sliding range of the fixing rod 24.
[0039] A spring 26 is sleeved on the outside of the limiting plate 25. The top of the spring 26 is fixedly connected to the top of the inner wall of the positioning cylinder 23. When the fixing rod 24 is pulled, the spring 26 is stretched and stores elastic potential energy. When the fixing rod 24 is released, the spring 26 releases the elastic potential energy, providing an upward pulling force to the fixing rod 24 through the limiting plate 25, helping the ball 32 to disengage from the slot 19, thus easily disassembling the fixing plate 20. The bottom end of the positioning cylinder 23 is fixedly connected to the top of the limiting plate 25. A thin shaft 27 is fixedly connected to the bottom end of the fixing rod 24. A first ball block 28 is fixedly connected to the outer middle of the thin shaft 27, and a second ball block 29 is fixedly connected to the bottom end of the thin shaft 27. The thin shaft 27 connects the fixing rod 24 and the first ball block 28.
[0040] The bottom end of the positioning cylinder 23 is fixedly connected to the locking rod 30. The outer side of the fixing rod 24 is slidably connected to the inner wall of the locking rod 30. The outer side of the second blocking ball 29 is slidably connected to the inner wall of the locking rod 30. The outer side of the first blocking ball 28 is slidably connected to the inner wall of the locking rod 30. The second blocking ball 29 and the first blocking ball 28 work together to further squeeze the locking ball 32 when the fixing rod 24 is pulled, ensuring that the locking ball 32 can completely disengage from the locking groove 19, so that the locking rod 30 can smoothly disengage from the locking groove 19, and ensuring that the fixing plate 20 can be easily removed from the air outlet pipe 18. The outer side of the locking rod 30 engages with the inner wall of the locking groove 19. Two grooves 31 are provided on the outer side of the locking rod 30. The outer side of the second blocking ball 29 engages with the outer side of the groove 31, and the outer side of the first blocking ball 28 engages with the outer side of the groove 31. The outer side of the groove 31 engages with the inner wall of the locking groove 19. The inner wall of the groove 31 is movably connected to the locking ball 32. The dimensions of the groove 31 and the locking ball 32 are matched, and the locking ball 32 can be accurately squeezed under the drive of the thin shaft 27 to realize the engagement and disengagement operation.
[0041] Working principle: In use, open the cover plate 15 and put the material to be processed into the melting chamber 13. Then, close the heating chamber 14 tightly at the top of the combustion chamber 2. Then, the fuel and oxygen in the two fuel and oxygen cylinders 3 are transported through the gas pump 4 and the flow valve 5. The flow valve 5 controls the flow rate of the fuel and oxygen in the two fuel and oxygen cylinders 3 and flows into the mixing pipe 7 through the connecting pipe 6. After the fuel and oxygen enter the mixing pipe 7, they will be diverted by the second baffle 9 and the first baffle 8 along the downward path of the mixing pipe 7 and then mixed again. This diversion and mixing is repeated until the two gas flows are fully mixed and then flows into the combustion chamber 2 through the air inlet pipe 10. At this time, the gas entering the combustion chamber 2 is ignited by the heating chamber 14 and the fuel in the combustion chamber 2, so that the fuel in the combustion chamber 2 and the mixed fuel and oxygen can be fully burned, increasing the heating effect of the device. In addition, the top of the cover plate 15 is connected through a pressurization pipe 17. The activated pressurization pump 16 will input air pressure into the combustion chamber 2 to control the air pressure in the combustion chamber 2 and achieve stable heating of the internal fuel.
[0042] The heated fuel will produce harmful gases that are discharged through the exhaust pipe 18. During discharge, the activated carbon plate 21 and filter bag 22 inside the exhaust pipe 18 will fully filter the harmful gases before they are discharged.
[0043] When the activated carbon plate 21 and filter bag 22, which need to be fixed by the fixing plate 20, need to be replaced and cleaned, the fixing rod 24 of the positioning cylinder 23 can be pressed and pulled. The bottom end of the fixing rod 24, through the thin shaft 27, presses the ball 32 moving in the groove 31 by the first ball 28 and the second ball 29, and then slides upward. During the upward sliding of the fixing rod 24, the stretched spring 26 will drive the limiting plate 25 and the fixing rod 24 to exert an upward force, so that the two balls 32 will retract to the inner wall of the locking rod 30 and engage at the angle between the second ball 29 and the first ball 28. This loosens the balls 32, and the locking rod 30 disengages from the slot 19, allowing the fixing plate 20 to easily remove the activated carbon plate 21 and filter bag 22 for cleaning and replacement.
[0044] 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.
