Description
Technical Field
[0001] This utility model relates to the field of iron and steel smelting technology, and in particular to an auxiliary device for reducing converter gas consumption. Background Technology
[0002] In the steel production process, converter steelmaking is a crucial step, and the effective utilization and controlled consumption of converter gas are of paramount importance.
[0003] Currently, excessive converter gas consumption is a major problem facing the industry. Traditional converter fume hood devices have many shortcomings. On the one hand, in terms of on / off control, most rely on manual operation, which is not only labor-intensive and increases the workload of workers, but also has a slow response time. It cannot adjust the opening and closing status of the fume hood in a timely manner according to the real-time emission of converter gas, resulting in inaccurate gas emission control and a large amount of converter gas waste. On the other hand, the sealing performance of the fume hood is not ideal. In the structural design of existing fume hoods, the connection between the inner and outer hoods is not tight enough, leaving gaps that allow converter gas to easily leak from these gaps. This not only reduces the gas recovery and utilization rate, but also increases energy consumption and environmental pollution risks. At the same time, the sensitivity of the fume hood opening and closing is difficult to adjust, failing to adapt to the emission requirements of converter gas under different operating conditions, further exacerbating gas waste and consumption.
[0004] Therefore, developing an auxiliary device that can automatically control the switch, has good sealing performance, and adjustable opening and closing sensitivity to reduce converter gas consumption has important practical significance and application value.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings mentioned in the background section by proposing an auxiliary device to reduce converter gas consumption.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an auxiliary device for reducing converter gas consumption, comprising an outer cover, an inner cover, two sector plates, two rotating shafts, a transmission assembly, and a guide and reset assembly;
[0008] The outer cover is axially slidably mounted on the outside of the inner cover. The support column is radially fixedly mounted on the inner wall of the inner cover. Both rotating shafts are axially rotatably mounted on the support column. The transmission assembly is located on the front side of the inner cover. The front ends of both rotating shafts extend to the front side of the inner cover and are connected to the transmission assembly. Two fan-shaped plates are radially fixedly mounted on their respective rotating shafts. A guide groove is provided on the inner wall of the inner cover. The outer edges of both fan-shaped plates are sealed and slidably mounted in the guide groove. The guide reset assembly is located on the inner wall of the inner cover and is adapted to the two fan-shaped plates.
[0009] Preferably, the transmission assembly includes two gears and a double-sided gear plate. The front ends of the two rotating shafts are fixedly fitted with gears, and the two gears are meshed with the same double-sided gear plate on the side that is close to each other.
[0010] Preferably, a support block is fixedly installed on the front side of the inner cover, and a double-sided toothed plate is slidably installed on the support block.
[0011] Preferably, a hook is fixedly installed at the bottom end of the double-sided toothed plate.
[0012] Preferably, the guide reset assembly includes a mounting base and four guide wheels. The mounting base is slidably mounted on the axis of the inner cover, and the four guide wheels are rotatably mounted on the mounting base.
[0013] Preferably, the guide reset assembly further includes an upper fixed rod, a lower fixed rod, and a guide square shaft. The upper fixed rod and the lower fixed rod are fixedly installed on the inner side wall of the inner cover in a parallel manner. The same guide square shaft is radially fixedly installed on the upper fixed rod and the lower fixed rod. The guide square shaft is located on the axis of the inner cover, and the mounting seat is slidably installed on the guide square shaft.
[0014] Preferably, multiple guide plates are fixedly installed on the outer side of the inner cover, and the side of the multiple guide plates closest to the inner cover is in sliding contact with the outer side of the outer cover.
[0015] Preferably, the outer side of the inner cover has two parallel annular grooves, and a sealing ring is fixedly installed in each of the two annular grooves. The outer sides of the two sealing rings are slidably connected to the inner wall of the outer cover.
[0016] The beneficial effects of this utility model are:
[0017] By cooperating with the transmission and guide reset components, the two sector plates can be controlled to flip synchronously upwards in opposite directions when the double-sided toothed plate moves downwards, thereby controlling the inner cover to be in the open state. The guide reset component can also drive the mounting base to slide upwards along the guide axis during the upward flipping of the sector plates. When the airflow discharged from the inner cover is insufficient to overcome the downward force on the sector plates, the self-weight of the mounting base and guide wheel is used to accelerate the automatic reset of the sector plates. The operation is convenient and does not require manual switching, reducing the labor intensity of the workers. The hook set at the bottom of the double-sided toothed plate allows for the addition of different weights at the bottom of the double-sided toothed plate according to the actual situation, thereby adjusting the force required for the sector plates to open and close, and thus adjusting the sensitivity of the inner cover opening and closing.
[0018] The coordinated design of components such as the outer cover, inner cover, guide groove, annular groove, sealing ring, and guide plate ensures that the inner cover slides stably along the inner wall of the outer cover, while also guaranteeing the airtightness of the connection between the inner and outer covers. This prevents converter gas from leaking through the gaps between the inner and outer covers, thereby reducing converter gas consumption and promoting energy conservation and environmental protection.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Reference Figure 1-7 An auxiliary device for reducing converter gas consumption includes an outer cover 1, an inner cover 2, two sector plates 32, and two rotating shafts 31. The outer cover 1 is axially slidably installed on the outside of the inner cover 2. A support column 3 is radially fixedly installed on the inner side wall of the inner cover 2. Both rotating shafts 31 are axially rotatably installed on the support column 3. The front ends of both rotating shafts 31 extend to the front side of the inner cover 2 and are respectively fixedly fitted with gears 331. The same double-sided toothed plate 332 is meshed on the side of the two gears 331 that are close to each other. When the double-sided toothed plate 332 moves downward, it can control the two sector plates 32 to rotate synchronously in the opposite direction upward, thereby controlling the opening and closing of the inner cover 2. The two sector plates 32 are radially fixedly installed on the corresponding rotating shafts 31. In order to facilitate the adjustment of the opening and closing sensitivity of the sector plates 32 by counterweighting the double-sided toothed plate 332, a hook 34 is fixedly installed at the bottom end of the double-sided toothed plate 332.
[0030] A guide groove 201 is provided on the inner wall of the inner cover 2. The outer edges of the two sector plates 32 are sealed and slidably installed in the guide groove 201. A mounting seat 43 is slidably installed on the axis of the inner cover 2. Four guide wheels 44 are rotatably installed on the mounting seat 43. When the sector plates 32 are flipped upward, the guide wheels 44 are squeezed. As the sector plates 32 continue to flip, the mounting seat 43 can be controlled to slide upward along the axis of the inner cover 2. An upper fixing rod 41 and a lower fixing rod 4 are fixedly installed on the inner wall of the inner cover 2. The same guide square shaft 42 is radially fixed on the upper fixing rod 41 and the lower fixing rod 4. The guide square shaft 42 is located on the axis of the inner cover 2, and the mounting seat 43 is slidably installed on the guide square shaft 42, which can provide stable guidance for the mounting seat 43.
[0031] In this embodiment, in order to provide a stable guide for the double-sided toothed plate 332 and thus ensure that the gear 331 and the double-sided toothed plate 332 maintain a stable meshing state, a support block 33 is fixedly installed on the front side of the inner cover 2, and the double-sided toothed plate 332 is slidably installed on the support block 33.
[0032] In this embodiment, in order to ensure that the inner cover 2 slides stably along the inner wall of the outer cover 1, and at the same time ensure the airtightness of the connection between the inner cover 2 and the outer cover 1, a plurality of guide plates 23 are fixedly installed on the outer side of the inner cover 2. The side of the plurality of guide plates 23 near the inner cover 2 is in sliding contact with the outer side of the outer cover 1. Two annular grooves 21 arranged in parallel to each other are opened on the outer side of the inner cover 2. A sealing ring 22 is fixedly installed in each of the two annular grooves 21. The outer side of the two sealing rings 22 is in a sealing sliding connection with the inner wall of the outer cover 1.
[0033] Working principle: In use, a suitable weight is first hung on the hook 34. The airflow through the outer cover 1 and inner cover 2 moves upward, which pushes the two fan-shaped plates 32 to deflect upward in opposite directions in a synchronized manner, thus keeping the inner cover 2 open. The opening of the inner cover 2 is automatically adjusted according to the speed of the airflow. During this process, the double-sided toothed plate 332 moves downward under the action of the two gears 331. When the opening is large, the fan-shaped plate 32 will squeeze the guide wheel 44 and cause the mounting base 43 to move along the guide square axis 42. Slide upwards to prevent the two sector plates 32 from deflecting to a vertical position and affecting the reset. When the airflow is small, the upward force on the sector plates 32 will be smaller, allowing the sector plates 32 to deflect downwards synchronously. At the same time, with the cooperation of the guide wheel 44 and the mounting base 43, the two sector plates 32 can be deflected downwards and reset. Since the bottom of the double-sided toothed plate 332 is fixedly installed with a hook 34, the sensitivity of the sector plate 32 to control the switch of the inner cover 2 can be adjusted by adding or removing counterweights.
[0034] The above provides a detailed description of an auxiliary device for reducing converter gas consumption provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
