Description

Technical Field

[0001] The present invention relates to the technical field of all-oxygen furnaces, and particularly to an all-oxygen furnace that changes the thermal load of the flame space according to the temperature. Background Art

[0002] As we know, the oxygen content in the air accounts for about 21%, and nitrogen and a small amount of other rare gases account for 79%. Nitrogen and a small amount of other gases do not participate in the combustion reaction. However, they are heated by the flame in the combustion reaction and absorb a large amount of heat. The high-temperature flue gas leaves the melting pool at about 1400°C and leaves the regenerator at 300 - 700°C (single-channel and three-channel regenerators), and a large amount of heat is discharged into the atmosphere, resulting in a large amount of heat loss. Nitrogen also reacts with the surplus oxygen at high temperatures to form nitrogen oxides. Nitrogen oxides are likely to form acid rain in the atmosphere, causing environmental pollution; Nowadays, most all-oxygen combustion kilns use vacuum pressure swing adsorption (VPSA) to produce oxygen, and the purity of oxygen is between 92 - 95%. Calculated according to 93% O2 purity, nitrogen and a small amount of other gases account for 7%. Therefore, the amount of high-temperature flue gas is reduced by about 70%. Due to the reduction of the flue gas volume, the heat carried away is reduced. Therefore, the all-oxygen combustion kiln is relatively energy-saving; When the all-oxygen furnace absorbs air, the dust impurities present in the air will affect the combustion effect. At the same time, in some areas with poor air quality and a large amount of willow catkins, the dust particles in the air are relatively large, which will block the ventilation ports. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: an all-oxygen furnace that changes the thermal load of the flame space according to the temperature, including a furnace box. Symmetrically arranged at the bottom of the outer surface of the furnace box are support feet, the top of the support feet is fixedly connected to the outer surface of the furnace box. Fixedly connected to the right side of the outer surface of the furnace box is a fuel tank. Fixedly connected to one end of the outer surface of the furnace box away from the fuel tank is an oxygen inlet mechanism. Fixedly connected to the top of the furnace box is a smoke outlet. Symmetrically arranged on the inner wall of the furnace box are igniters, and the outer surface of the igniters is fixedly connected to the inner wall of the furnace box. Fixedly connected to the bottom of the furnace box is an alkali cleaning mechanism; When the device works, air is inhaled into the device through the oxygen inlet mechanism, combined with fuel and ignited by the igniter to form combustion.

[0004] The oxygen inlet mechanism includes an air pipe. Fixedly connected to the bottom of the air pipe is an air box. Fixedly connected to one end of the air box away from the air pipe is a filtering mechanism. Fixedly connected to the outer surface of the air box is a cleaning mechanism. Fixedly connected to the inner wall of the air box is a fixing plate, and a suction device is fixed to the outer surface of the fixing plate; During the process of the air intake device sucking in air, the air will pass through the ventilation openings on the isolation plate. The isolation plate will block the dust present in the air, preventing impurities in the air from participating in combustion and thus affecting the quality of combustion.

[0005] The filtering mechanism includes an isolation plate. The outer surface of the isolation plate is evenly provided with ventilation openings. One end of the isolation plate close to the ventilation openings is fixedly connected to a first support rod. The end of the first support rod far from the isolation plate is fixedly connected to a third support plate. One side of the third support plate close to the first support rod is fixedly connected to a first telescopic spring. The end of the first telescopic spring far from the third support plate is fixedly connected to a first magnetic block. The end of the first magnetic block far from the first telescopic spring is fixedly connected to a scraping block.

[0006] When the magnetic plate moves to be horizontal with the ventilation opening, the magnetic plate will attract the first magnetic block, thereby pulling the first telescopic spring and driving the scraping block to squeeze out the blocked dust and impurities from the ventilation opening.

[0007] Preferably, the top of the air pipe is fixedly connected to the outer surface of the furnace box, and the outer surface of the isolation plate is fixedly connected to the end of the air box far from the air pipe.

[0008] Preferably, the cleaning mechanism includes a first support plate. The first support plates are symmetrically arranged at the top and bottom of the air box. A first servo motor is fixedly connected to the top of the first support plate located at the top. A lead screw is rotatably connected to the opposite surfaces of the first support plates. A sliding block is slidably connected to the outer surface of the lead screw. Second support plates are symmetrically arranged at the end of the air box far from the first support plate. The outer surfaces of the second support plates are fixedly connected to the top and bottom of the air box. A guide rod is fixedly connected to the opposite surfaces of the second support plates. The end of the sliding plate far from the lead screw is slidably connected to the outer surface of the guide rod. A magnetic plate is fixedly connected to the outer surface of the sliding plate. Rubber rings are evenly arranged on the side of the sliding plate far from the magnetic plate. One end of the rubber ring close to the sliding plate is fixedly connected to the outer surface of the sliding plate.

[0009] The first servo motor drives the lead screw to rotate, thereby causing the sliding plate to slide up and down along one end of the guide rod. During the up and down movement of the sliding plate, the rubber rings will scrape the outer surface of the isolation plate, thereby removing the adhered dust.

[0010] Preferably, a bottom plate is fixedly connected to the outer surface of the first support plate. Support columns are evenly arranged on the top of the bottom plate. The bottom of the support columns is fixedly connected to the top of the bottom plate. The top of the support columns is fixedly connected to an extrusion block. Impact rods are fixedly connected to the outer surfaces of the support columns.

[0011] When the sliding plate moves to the bottom, the extrusion block will squeeze out the dust inside the rubber ring. At the same time, the impact rods will impact the sliding plate, and the generated vibration will cause the dust adhered to the sliding plate to fall off, thus realizing self-cleaning.

[0012] Preferably, one side of the first support plate close to the air box is fixedly connected to the outer surface of the air box, and one end of the bottom plate away from the first support plate is fixedly connected to the outer surface of the second support plate.

[0013] Preferably, the alkali cleaning mechanism includes a second support rod, the second support rods are symmetrically arranged at the bottom of the furnace box, a fourth support plate is fixedly connected to the bottom of the second support rod, a telescopic rod is fixedly connected to the top of the fourth support plate, a second servo motor is fixedly connected to the top of the telescopic rod, a scraping mechanism is rotatably connected to the top of the second servo motor, third support rods are symmetrically arranged on the outer surface of the second support rod, and a magnetic ring is fixedly connected to the opposite surfaces of the third support rods.

[0014] After stopping combustion, the scraping mechanism is moved into the furnace box through the telescopic rod, and the second servo motor drives the rotating column to rotate.

[0015] Preferably, the top of the second support rod is fixedly connected to the bottom of the furnace box.

[0016] Preferably, the scraping mechanism includes a rotating column, a bottom plate is fixedly connected to the top of the rotating column, a second telescopic spring is fixedly connected to the inner wall of the rotating column, a cleaning plate is fixedly connected to one end of the second telescopic spring away from the rotating column, scraping rings are evenly arranged at the bottom of the cleaning plate, the top of the scraping rings is fixedly connected to the bottom of the cleaning plate, a shoveling plate is fixedly connected to one side of the cleaning plate away from the second telescopic spring, a second magnetic block is slidably connected to one side of the shoveling plate close to the cleaning plate, and a scraping plate is fixedly connected to the outer surface of the second magnetic block.

[0017] The centrifugal force generated by rotation stretches the second telescopic spring and makes the scraping rings scrape the bottom edge of the furnace box, so that the mud is scraped. After the rotating column stops rotating, the second telescopic spring pulls back the shoveling plate to shovel out the generated mud from the device. At the same time, when the telescopic rod moves up and down, the shoveling plate will pass through the magnetic ring, so that the magnetic ring attracts the second magnetic block to move along the shoveling plate and drives the scraping plate to remove the mud adhered to the shoveling plate, thus realizing self-cleaning.

[0018] Preferably, the bottom of the rotating column is rotatably connected to the top of the second servo motor.

[0019] The beneficial effects of the present invention are as follows: (1) By setting the filtering mechanism in the present invention, during the process of the air suction device sucking air, the air will pass through the ventilation openings on the isolation plate, and the isolation plate will block the dust existing in the air, avoiding the participation of impurities in the air in combustion, thereby affecting the combustion quality. However, when the dust in the air is relatively large, the large dust impurities will block the ventilation openings, thus affecting the air entering the device.

[0020] (2) By setting up a cleaning mechanism in the present invention, the servo motor 1 drives the lead screw to rotate, so that the sliding plate slides up and down along one end of the guide rod, thereby driving the magnetic plate to move up and down. When the magnetic plate moves to be horizontal with the ventilation port, the magnetic plate will attract the magnetic block 1, thereby pulling the telescopic spring 1 and driving the scraping block to squeeze out the blocked dust and impurities from the ventilation port.

[0021] (3) By setting up a cleaning mechanism in the present invention, during the up and down movement of the sliding plate, the rubber ring will scrape the outer surface of the isolation plate, thereby removing the adhered dust. When the sliding plate moves to the bottom, the extrusion block will squeeze out the dust inside the rubber ring. At the same time, the impact rod will impact the sliding plate, and the generated vibration will cause the dust adhered to the sliding plate to fall off, thereby realizing self-cleaning.

[0022] (4) By setting up an alkali cleaning mechanism in the present invention, during the combustion process inside the device, the dust is inhaled into the smoke exhaust port. Especially for alkaline dust, it is lighter in mass and easier to enter the flue. It is wetted by the water vapor in the flue gas and sinks to the bottom edge of the furnace box. Therefore, the alkali content in the mud at the bottom is particularly high and needs to be cleaned. After stopping the combustion, the scraping mechanism is moved into the furnace box through the telescopic rod. The servo motor 2 drives the rotating column to rotate, and the generated centrifugal force causes the telescopic spring 2 to stretch, and the scraping ring scrapes the bottom edge of the furnace box, so that the mud is scraped. After the rotating column stops rotating, the telescopic spring 2 pulls back the shoveling plate, thereby shoveling out the generated mud from the device.

[0023] (5) By setting up a scraping mechanism in the present invention, during the up and down movement of the telescopic rod, the shoveling plate will pass through the magnetic ring, so that the magnetic ring attracts the magnetic block 2 to move along the shoveling plate, and drives the scraping plate to remove the mud adhered to the shoveling plate, thereby realizing self-cleaning.

[0033] The servo motor 1 drives the lead screw 543 to rotate, so that the sliding plate 544 slides up and down along one end of the guide rod 546.

[0039] The top of the second support rod 71 is fixedly connected to the bottom of the furnace box 1.

[0040] The scraping mechanism 75 includes a rotating column 751. A bottom plate 752 is fixedly connected to the top of the rotating column 751.

[0043] The specific working process is as follows: During operation, air is inhaled into the device through the oxygen inlet mechanism 5, combined with fuel and ignited by the igniter 6 to form combustion. When the air intake device 57 absorbs air, the air will pass through the air vent 532 on the isolation plate 531. The isolation plate 531 blocks the dust in the air, preventing impurities in the air from participating in combustion and affecting the combustion quality. However, when there is a large amount of dust in the air, the large dust impurities will block the air vent 532. The first servo motor 542 drives the lead screw 543 to rotate, causing the sliding plate 544 to slide up and down along one end of the guide rod 546, thereby driving the magnetic plate 547 to move up and down. When the magnetic plate 547 moves to be horizontal with the air vent 532, the magnetic plate 547 will attract the first magnetic block 536, thereby pulling the first telescopic spring 535 and driving the rubbing block 537 to squeeze out the blocked dust impurities from the air vent 532. During the up and down movement of the sliding plate 544, the rubber ring 548 will rub against the outer surface of the isolation plate 531, thereby removing the adhering dust. When the sliding plate 544 moves to the bottom, the extrusion block 5410 will squeeze out the dust inside the rubber ring 548. At the same time, the impact rod 5411 will impact the sliding plate 544, and the generated vibration will cause the dust adhering to the sliding plate 544 to fall off, thereby achieving self-cleaning. After stopping combustion, the rubbing mechanism 75 is moved into the furnace box 1 through the telescopic rod 73. The second servo motor 74 drives the rotating column 751 to rotate, and the generated centrifugal force stretches the second telescopic spring 753, causing the rubbing ring 755 to rub against the bottom edge of the furnace box 1, thereby scraping the mud. After the rotating column 751 stops rotating, the second telescopic spring 753 pulls back the shoveling plate 756, thus shoveling out the generated mud from the device. Finally, during the up and down movement of the telescopic rod 73, the shoveling plate 756 will pass through the magnetic ring 77, causing the magnetic ring 77 to attract the second magnetic block 757 to move along the shoveling plate 756 and drive the scraping plate 758 to remove the mud adhering to the shoveling plate 756, thereby achieving self-cleaning.
