In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three or more, etc., unless otherwise clearly specified and limited.

[0040] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] In order to solve the problems existing in the prior art, an embodiment of the present application provides a fume collection device for copper smelting in a converter process.

[0042] like Figure 1 and Figure 2 As shown, a fume collection device for copper smelting in a converter process includes a collecting barrel 1, an air intake adjustment component 2, a filter component 3 and an exhaust device 4; the collecting barrel 1 is provided with an air inlet 11 and an exhaust port 12, the air inlet 11 is used to connect to external smoke exhaust equipment, and the exhaust port 12 is used to connect to subsequent smoke treatment equipment; the air intake adjustment component 2 is arranged at the air inlet 11, for adjusting the flow rate of smoke entering the collecting barrel 1; the filter component 3 is arranged in the collecting barrel 1, and is located between the air inlet 11 and the exhaust port 12 to filter the smoke; the exhaust device 4 is used to transport the external smoke into the collecting barrel 1.

[0043] The present invention provides a fume collection device for copper smelting in a converter process. The device is based on the coordinated use of an air intake adjustment component and an exhaust device. When the flue gas volume is large, the air intake adjustment component is adjusted to reduce the air intake volume. When the flue gas volume is too small, the air intake adjustment component is adjusted to increase the air intake volume, thereby maintaining the stability of the flue gas volume. This reduces the burden on equipment such as fans and pipelines caused by the large amount of flue gas, extends the service life of the device, and avoids the waste of resources caused by too little flue gas flowing into the device.

[0044] In some preferred embodiments, the exhaust device 4 is an induced draft fan, which is arranged at the exhaust port 12; based on this, the flue gas passing through the induced draft fan is filtered flue gas, which reduces damage to the induced draft fan.

[0045] In some preferred embodiments, the air intake adjustment component 2 is disposed in the collection barrel 1 .

[0046] In some preferred embodiments, the air inlet 11 and the air outlet 12 are relatively arranged on two sides of the collecting barrel 1 , such as on two sides of the collecting barrel 1 along the axial direction.

[0047] In some preferred embodiments, Figure 3As shown, the air intake adjustment component 2 includes a driving component 21 and a plurality of baffles 22; the plurality of baffles 22 can move closer to or away from each other under the drive of the driving component 21, and there are a plurality of baffles 22 on the moving line to jointly block the blocking position of the air inlet 11 and the open position of the air inlet 11 that is fully opened, and when the plurality of baffles 22 are in the position between the blocking position and the open position, a channel with a cross-section radially extending from the inside to the edge of the air inlet 11 is formed; based on this, the maximum range of air intake flow can be adjusted, and based on the formation of a radial channel at the position between the closed position and the open position, that is, it can circulate not only near the middle of the air inlet 11, but also near the edge of the air inlet 11. As a result, the dispersion of the smoke can be improved, and the smoke can be evenly distributed when entering the collection barrel 1, avoiding uneven use of the filter component 3 caused by the concentrated flow of smoke, affecting the filtering effect, and causing premature replacement.

[0048] Optionally, when the multiple baffles 22 are in the blocking position, their edges may be fitted together or overlapped with each other to block the air inlet 11 .

[0049] Preferably, the movement direction of each baffle 22 is from the center to the edge of the air inlet 11, and when multiple baffles 22 are in the blocking position, the edges of the baffles 22 fit together; based on the edge-fitting setting, the baffle 22 can be restricted from further movement in the blocking position, making it easier to confirm that the blocking is in place during operation.

[0051] Further preferably, the baffle 22 is formed by dividing the central angle of a circular plate into at least three equal parts, such as 8 equal parts, and the moving direction is the radial direction of the symmetry axis; based on this, the channel formed is more uniform and the dispersion of the flue gas is better.

[0055] In some preferred embodiments, Figure 2 and Figure 3 As shown, a driving assembly 21 and a plurality of baffles 22 are arranged in the collecting barrel 1, and the air intake adjustment assembly 2 also includes an operating rod 23; one end of the operating rod 23 is connected to the driving assembly 21, and the other end extends out of the collecting barrel 1 through the guide groove 13 on the collecting barrel 1, and the driving assembly 21 is driven by the operating rod 23; specifically, the operating rod 23 is connected to the ring gear 211.

Then the limiting ring 33 is released, so that the clamping member 32 restricts the filter plate 31 again, thereby achieving the replacement of the filter plate 31. Then, the air inlet 11 is connected to the exhaust pipe of the converter copper smelting device. Then, when the converter copper smelting device is in operation, flue gas will be generated. At this time, the exhaust device 4 on the exhaust port 12 is started. At this time, the flue gas will be sucked into the collection bucket 1 by the exhaust device 4. The amount of flue gas entering the collection bucket 1 can be adjusted according to actual conditions. When adjusting, it is only necessary to rotate the operating lever 23. At this time, the operating lever 23 will rotate with the ring gear 211. At this time, the ring gear 211 will rotate on the first mounting bracket 214. When the operating lever 23 moves, it will move in the guide groove 13. The movement of the ring gear 211 will drive the gear of the rack and pinion assembly 212 to rotate. When the gear rotates, the rack of the rack and pinion assembly 212 will move closer to or away from each other. When the rack moves, it will slide on the slider 213. When the rack moves, the baffle 22 will also move. , when the baffles 22 are close to each other, the adjustment can be reduced, and similarly, when they are away from each other, the adjustment can be increased, thereby achieving the goal of controlling the amount of entry by adjusting the gap between the baffles 22. After the smoke enters, it will be filtered by the filter plate 31, and at this time, the driving member 371 is started. When the driving member 371 rotates, the cleaning member 372 will also rotate accordingly. As the cleaning member 372 rotates, the impurities on the filter plate 31 will be scraped off. As the cleaning member 372 rotates, it will contact the knocking member 383. When it contacts the knocking member 383, the knocking member 383 will be pushed into the guide member 384. At this time, the second elastic member 382 will be squeezed, and after the cleaning member 372 passes through the knocking member 383, the second elastic member 382 will quickly push the knocking member 383 toward the filter plate 31, thereby knocking the filter plate 31, thereby achieving a vibration effect.
