Description

Technical Field

[0001] The invention relates to the technical field of steelmaking equipment, and more specifically to an environmentally friendly steelmaking furnace with a waste gas treatment function. Background Art

[0002] Steel is a general term for iron-carbon alloys with a carbon content ranging from 0.02% to 2.11% by mass. Human beings have a long history of application and research on steel, but until the invention of the Bain steelmaking process in the 19th century, the production of steel was a high-cost and low-efficiency task. Today, steel has become one of the most widely used materials in the world with its low price and reliable performance. It is an indispensable component in the construction industry, manufacturing industry and people's daily life. Steel is obtained by putting pig iron for steelmaking into a steelmaking furnace and melting it according to a certain process.

[0003] In order to achieve the purpose of environmental protection, some existing steel-making furnaces currently install a filter box on the outside of the steel-making furnace. After the exhaust gas generated by the steel-making furnace is directly passed into the filter box, the exhaust gas is purified by the filter plate in the filter box. At the same time, in order to clean the filter plate in the filter box, the cleaning brush is driven up and down by mechanisms such as the screw slider to achieve the purpose of cleaning the impurities on the filter plate. However, since the cleaning brush is always inside the filter box and is directly exposed, after the exhaust gas enters the filter box, many impurities in the exhaust gas will directly contaminate the cleaning brush. In this way, not only the cleaning effect of the cleaning brush on the impurities is reduced, but also when the contaminated cleaning brush cleans the filter plate, it will contaminate the filter plate again, thereby affecting the filtering effect of the filter plate. Therefore, we provide an environmentally friendly steel-making furnace with exhaust gas treatment function. Summary of the invention

[0004] The object of the present invention is to provide an environmentally friendly steelmaking furnace with waste gas treatment function to solve the problems raised in the above background technology: In order to achieve the purpose of environmental protection, some existing steel-making furnaces are equipped with filter boxes outside the steel-making furnace.

At the same time, in order to clean the filter plate in the filter box, the cleaning brush is driven up and down by mechanisms such as the screw slider to achieve the purpose of cleaning the impurities on the filter plate. However, since the cleaning brush is always inside the filter box and is directly exposed, after the exhaust gas enters the filter box, many impurities in the exhaust gas will directly contaminate the cleaning brush. In this way, not only the cleaning effect of the cleaning brush on the impurities is reduced, but also when the contaminated cleaning brush cleans the filter plate, it will contaminate the filter plate again, thereby affecting the filtering effect of the filter plate.

[0007] Preferably, the cross section of the first limiting block is a T-shaped structure, and the first limiting block of the T-shaped structure cooperates with the first limiting groove to limit the rack, so that the rack moves more smoothly.

[0008] Preferably, a circular plate is sleeved on the outside of the first rotating shaft and located on one side of the mounting plate, and a torsion spring is sleeved on the outside of the first rotating shaft and located between the circular plate and the mounting plate. One end of the torsion spring is fixedly connected to the mounting plate, and the other end of the torsion spring is fixedly connected to the circular plate. The torsion force of the torsion spring can cooperate with the circular plate to drive the first rotating shaft to rotate, and cooperate with the rack and the first gear to give the cleaning brush a tendency to automatically extend to the outside of the shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1) When the environmentally friendly steelmaking furnace with exhaust gas treatment function is in use, the servo motor rotates in the opposite direction and the shell moves upward. During the process, the cleaning brush will be retracted into the shell, and then the two baffles will approach each other and close again, so that the cleaning brush will not be directly exposed to the outside world. When the exhaust gas enters the filter box, it will not directly pollute the cleaning brush, thus avoiding the secondary pollution of the filter plate caused by the cleaning brush when cleaning the filter plate.

[0014] 2) When the environment-friendly steelmaking furnace with waste gas treatment function is in use, the shell drives the extended cleaning brush to move downward to automatically clean the filter plate. The shell also drives the sealing plate to rotate downward and open through the chain. The impurities swept down fall into the collection box through the collection port and finally fall into the collection pipe. After cleaning, the shell moves upward and returns to its original position. The shell again drives the sealing plate to rotate upward and close using the chain to block the collection port, thereby preventing the waste gas from directly entering the collection box and the collection pipe, and avoiding the impurities that have been collected from being blown up again to cause pollution.

[0015] 3) When the environment-friendly steelmaking furnace with waste gas treatment function is in use, when the filter plate needs to be cleaned, the servo motor is started to rotate forward, so that the screw drives the shell to move downward, and under the action of the third slide groove and the third slide rod, the rotating plate drives the second gear to rotate 180 degrees, and the second gear drives the second rotating shaft to rotate through the third gear, and the second rotating shaft drives the swing plate to rotate in the direction away from the rack, and drives the first gear to rotate under the action of the first slide groove and the first slide rod, and the first gear drives the cleaning brush to extend to the outside of the shell through the rack, and at the same time, the swing plate drives the two baffles to separate and open up and down through the second slide groove and the second slide rod until the cleaning brush is completely extended out of the shell and pressed against the filter plate, and as the shell continues to move downward, the cleaning brush pressed against the filter plate can automatically clean the impurities on the filter plate.

During the process, the inner wall of the first slide groove 1010 squeezes the first slide bar 1011, thereby driving the first gear 1007 to rotate. The first gear 1007 then drives the cleaning brush 1004 to extend to the outside of the housing 8 through the rack 1001. At the same time, the swing plate 1009 squeezes the second slide bar 1011 through the inner wall of the second slide groove 1012. 13, so that the second slide bar 1013 cooperates with the connecting plate 1014 to drive the two baffles 9 to separate and open up and down, until the cleaning brush 1004 is completely extended out of the shell 8 and pressed against the filter plate 5, and the shell 8 moving downward will drive the sealing plate 21 to rotate downward and open through the chain 14. As the shell 8 continues to move downward, the cleaning brush 1004 pressed against the filter plate 5 can automatically clean the impurities on the filter plate 5. The cleaned impurities will fall into the collection box 17 through the collection port 20 and finally fall into the collection pipe 18. When the servo motor 6 reverses, The shell 8 will move upward until it returns to its initial position. During the process, the cleaning brush 1004 will automatically retract into the shell 8, and then the two baffles 9 will approach each other and close again. When the exhaust gas enters the filter box 3 again, it cannot directly pollute the cleaning brush 1004, thereby avoiding secondary pollution caused by the cleaning brush 1004 when cleaning the filter plate 5. At the same time, the shell 8 uses the chain 14 to drive the sealing plate 21 to seal the collection port 20, which can prevent the exhaust gas from directly entering the collection box 17 and the collection pipe 18, thereby avoiding the impurities that have been collected from being blown up again to cause pollution.
