[0057] During the non-ferrous metal smelting process, since most of the smelting raw materials are metal sulfides, a large amount of sulfur-containing flue gas is inevitably produced during the smelting process, and the discharge of sulfur-containing flue gas into the environment will cause environmental pollution. At the same time, the flue gas also contains various valuable elements that can be extracted, such as flue gas acid production, which can create benefits for the enterprise and reduce the environmental risks brought about by the escape of flue gas during the smelting process. In the prior art, during the metal smelting process, the control and management measures for flue gas are generally to use fixed matching smoke hoods to collect smoke and dust for each metal smelting equipment. However, due to the large number of metal smelting equipment on site, the inclination angle of the smoke hoods matched with each equipment is different, resulting in poor flexibility in the use of fixed smoke hoods for smoke collection, and each smoke exhaust chute cannot be completely and tightly covered, which in turn leads to smoke escape, resulting in poor working conditions in the smelting emission area, and there are safety and environmental risks. In response to the above problems, the following embodiments are proposed:

[0058] In certain embodiments, as Figure 1 As shown, the present application proposes an angle-adjustable movable lifting smoke guide device. Taking the angle-adjustable movable lifting smoke guide device placed upright on a horizontal plane as an example, the direction toward the top of the angle-adjustable movable lifting smoke guide device is upward, the direction toward the bottom of the angle-adjustable movable lifting smoke guide device is downward, the direction toward the front of the angle-adjustable movable lifting smoke guide device is forward, the direction toward the rear of the angle-adjustable movable lifting smoke guide device is backward, the direction toward the left of the angle-adjustable movable lifting smoke guide device is left, and the direction toward the right of the angle-adjustable movable lifting smoke guide device is right. The angle-adjustable movable lifting smoke guide device includes: a track 1000, a frame assembly 2000, a moving assembly 3000, a lifting assembly 4000 and a smoke hood assembly 5000; the track 1000 extends along a first preset direction; the first preset direction is the front-to-back direction, the moving assembly 3000 is arranged on the frame assembly 2000 and connected to the track 1000, and the frame assembly 2000 moves along the track 1000 by being driven by the moving assembly 3000; the lifting assembly 4000 is arranged on the frame assembly 2000, and an adjustable chain group 4600 is provided on the lifting assembly 4000; the smoke hood assembly 5000 is connected to the adjustable chain group 4600, and the adjustable chain group 4600 is used to adjust the inclination angle of the smoke hood assembly 5000, and the smoke hood assembly 5000 moves in the up and down directions by being driven by the lifting assembly 4000.

[0059] It can be understood that the moving assembly 3000 is fixed on the frame assembly 2000, and the moving assembly 3000 drives the frame assembly 2000 to slide along the track 1000, and slides to the top of the metal smelting equipment that needs to exhaust smoke. The lifting assembly 4000 is set on the frame assembly 2000 and moves up and down along the frame assembly 2000 to move the smoke hood assembly 5000 to the exhaust chute close to the metal smelting equipment, and drives the adjustable chain group 4600 to move up and down. At the same time, the adjustable chain group 4600 is adjusted according to the inclination angle of the exhaust chute. 0, adjust the smoke hood assembly 5000 to an angle that is compatible with the smoke exhaust chute, so that the smoke hood assembly 5000 completely and tightly covers the smoke exhaust chute. The smoke hood assembly 5000 is used to collect and guide smoke, and the angle can be adjusted according to the angle of the discharge chute through the adjustment of the lifting assembly 4000 and the adjustable chain group 4600. The adjustment range can reach 0-20°, which is convenient for the smoke hood assembly 5000 to form the best smoke collection angle with the chute and the smoke collection hood of the environmental protection fan, thereby improving the smoke collection efficiency and avoiding smoke escape. At the same time, it ensures the working condition of the smelting emission area and reduces safety and environmental protection risks.

[0060] like Figure 1 As shown, in the specific structure of this embodiment, tracks 1000 are provided at both ends of the left and right ends of the angle-adjustable movable lifting smoke guide device, and the tracks 1000 at the left and right ends of the angle-adjustable movable lifting smoke guide device are symmetrically arranged, and the tracks 1000 are connected to a track frame 1100, and the track frame 1100 is fixed on the wall.

[0061] In some embodiments, in order to raise the angle-adjustable movable lifting smoke guide device, a track 1000 may also be provided above the track frame 1100. At this time, it is necessary to ensure that the distance between the upper and lower tracks 1000 is greater than the height of the first frame member 2100, so that the angle-adjustable movable lifting smoke guide device has sufficient space when moving back and forth in the upper and lower tracks 1000, and runs smoothly.

[0062] like Figure 1 and Figure 6 As shown, in the specific structure of this embodiment, the frame assembly 2000 includes a first frame member 2100 and a second frame member 2200, the second frame member 2200 is located on one side of the first frame member 2100, and the second frame member 2200 is extended downward; the second frame member 2200 includes: a third frame 2210 and a fourth frame 2220, the third frame 2210 is located on one side of the first frame member 2100, and is connected to the first frame member 2100; the fourth frame 2220 is located below the third frame 2210, and is extended downward, and the fourth frame 2220 is adjustably connected to the third frame 2210.

[0063] It can be understood that the frame assembly 2000 includes a first frame member 2100 and a second frame member 2200, the moving assembly is arranged above the first frame member 2100, the second frame member 2200 extends downward, the lifting assembly 4000 is arranged below the first frame member 2100, and is arranged on one side of the second frame member 2200, and the second frame member 2200 is arranged to include a third frame 2210 and a fourth frame 2220, and one end of the third frame 2210 is connected to the first frame member 2100, and the other end is connected to the fourth frame 2220, and the third frame 2210 and the fourth frame 2220 are fixedly connected to the first frame member 2100 so that they move back and forth with the first frame member 2100. At the same time, the fourth frame 2220 is adjustably connected to the third frame 2210, and the height of the fourth frame 2220 can be adjusted as needed to increase or decrease the height of the second frame member 2200 as a whole, which is suitable for different application scenarios.

[0064] like Figure 5 As shown, in the specific structure of this embodiment, the first frame member 2100 includes: a main beam 2110, a side panel 2120, a wing panel 2130 and a baffle 2140; the two side panels 2120 are respectively arranged at the two ends of the main beam 2110 in the left and right directions; the wing panels 2130 are respectively arranged at the two ends of the main beam 2110 in the front and rear directions, and are respectively arranged in the direction of the side panels 2120; the baffle 2140 is located above the main beam 2110 and is arranged parallel to the side panels 2120.

[0065] It can be understood that the main beam 2110 provides support for the entire angle-adjustable movable lifting smoke guide device, and by respectively arranging side panels 2120, wing panels 2130 and baffles 2140 on the main beam 2110, the side panels 2120 and the baffles 2140 firmly support the first rotating shaft 3100 in the movable component 3000. At the same time, the side panels 2120 also provide attachment and support for the walking wheels 3300 and the guide wheels 3400 in the movable component 3000, and the wing panels 2130 provide support for the follower cam 3500 in the movable component 3000, ensuring that when the movable component 3000 moves along the track 1000, the entire angle-adjustable movable lifting smoke guide device follows the movement.

[0066] In some embodiments, the side panels 2120 and the baffles 2140 are the same in number, with two each provided. Four wing panels 2130 may be provided. Two are provided on each side of the main beam 2110, each of which is provided close to the side panels 2120. In this way, four follower cams 3500 can be provided, with two provided next to each track 1000, to ensure that each follower cam 3500 is supported.

[0067] like Figure 4 As shown, in the specific structure of this embodiment, the moving component 3000 includes: a first rotating shaft 3100, a first motor 3200, a walking wheel 3300, a guide wheel component 3400 and a follower cam 3500; the first rotating shaft 3100 is arranged in parallel above the main beam 2110 and is connected to the two side plates 2120; the first motor 3200 is arranged on the first rotating shaft 3100; the two walking wheels 3300 are respectively arranged at the ends of the first rotating shaft 3100 and are respectively connected to the outer sides of the two side plates 2120; the guide wheel component 3400 is arranged at the end of the main beam 2110 and is located below the walking wheel 3300; the follower cam 3500 is located between the walking wheel 3300 and the guide wheel component 3400 and is arranged above the wing plate 2130.

[0068] It is understood that when the first motor 3200 is powered on, the first motor 3200 drives the first rotating shaft 3100 to rotate, which in turn drives the running wheel 3300 to rotate. The running wheel 3300 moves along the track 1000, driving the guide wheel 3400 and the follower cam 3500 to follow the running wheel 3300 in moving along the track 1000. The first rotating shaft 3100, the first motor 3200, the running wheel 3300, the guide wheel 3400, and the follower cam 3500 are all connected to the main beam 2110, ensuring the compactness of the overall structure of the moving assembly 3000 during movement.

[0069] In certain embodiments, the first motor 3200 may utilize a three-in-one reducer. The first motor 3200 is provided with a reduction mechanism and a locking mechanism. When the moving assembly 3000 reaches a certain position and needs to stop, the reduction mechanism is used to reduce speed. When the moving assembly 3000 reaches a desired position and needs to be fixed for smoke exhaust, the locking mechanism is used to position the assembly. This greatly facilitates the operation and positioning of the moving assembly 3000. Specifically, the moving assembly 3000 is fixedly mounted on the first frame member 2100. When the first motor 3200 loses power, its retraction function is automatically released, allowing manual movement of the moving assembly 3000, thereby facilitating repairs in the event of a malfunction or manual operation during a power outage.

[0070] In certain embodiments, as Figure 4 As shown, the running wheel 3300 is also provided with a wheel cover 3310. The wheel cover 3310 is arranged on the side plate 2120 and fixed to the side plate 2120 via the bolt connection method, ensuring that the lower side of the running wheel 3300 is exposed and contacts the upper surface of the track 1000. Two follower cams 3500 are provided, one on each side of the side plate 2120. The two follower cams 3500 are located on the side of the track 1000 facing the moving assembly 3000 and are in close contact with the side surface. At the same time, the guide wheel assembly 3400 is located below the track 1000 and contacts the lower surface of the track 1000. The guide wheel assembly 3400 includes two guide wheels, which are arranged side by side and form a triangular structure with the running wheel 3300. This triangular structure promotes the stability and reliability of the running of the moving assembly 3000.

[0071] In some embodiments, the running wheel 3300 is connected to the side plate 2120 via a second connecting plate, and the second connecting plate can be fixedly connected to the side plate 2120 by bolts or welding. Figure 4 As shown, the follower cam 3500 is connected to the wing plate 2130 through a fixed adjusting member 3510, and a bar-shaped through hole is provided at the bottom of the fixed adjusting member 3510. The fixed adjusting member 3510 is fixed to the wing plate 2130 through the bar-shaped through hole. One side of the fixed adjusting member 3510 is connected to the follower cam 3500, and the other side is provided with a first adjusting rod. The position of the follower cam 3500 can be adjusted by adjusting the first adjusting rod so that it fits more closely with the track 1000.

[0072] like Figure 2As shown, in the specific structure of this embodiment, a first connecting plate 2111 is provided above the main beam 2110, and a first bending plate 2112 is connected to the first motor 3200; a second bending plate 2113 is provided between the first bending plate 2112 and the first connecting plate 2111, and the second bending plate 2113 is connected to the first bending plate 2112 and the first connecting plate 2111 by bolts.

[0073] It can be understood that by connecting the first bent plate 2112 to the first motor 3200, the second bent plate 2113 having one end connected to the first bent plate 2112 and the other end connected to the first connecting plate 2111, and the first connecting plate 2111 connected to the main beam 2110, the first motor 3200 is securely fixed to the main beam 2110 and drives the first rotating shaft 3100 to rotate. Specifically, the first connecting plate 2111 can be connected to the main beam 2110 by welding, and the side of the first bent plate 2112 facing the first motor 3200 is provided with a threaded hole, which can be connected to the first motor 3200 using bolts. The side where the first bent plate 2112 and the second bent plate 2113 are connected to each other, and the side where the second bent plate 2113 and the first connecting plate 2111 are connected to each other, are provided with strip-shaped holes. The strip-shaped holes are arranged in a cross-staggered manner, allowing the position of the bolt connection to be changed as needed, increasing the flexibility of the connection and avoiding the problem of precise hole alignment during production, thereby reducing production precision and increasing production efficiency. It is easy to imagine that four bar holes are provided on one side where the first bending plate 2112 and the second bending plate 2113 are connected to each other, and on one side where the second bending plate 2113 and the first connecting plate 2111 are connected to each other, so as to increase the firmness of the connection.

[0074] In some embodiments, the bending sides of the first bending plate 2112 and the second bending plate 2113 are both provided with reinforcing ribs to make the connection more secure.

[0075] like Figure 2 and Figure 5 As shown, in the specific structure of this embodiment, a first groove 2121 is provided on the side plate 2120, and a second groove 2141 is provided on the baffle 2140; the first rotating shaft 3100 is connected to the side plate 2120 and the baffle 2140 through the first groove 2121 and the second groove 2141 respectively.

[0076] It can be understood that the side plate 2120 is provided with a first groove 2121, and the baffle 2140 is provided with a second groove 2141. The first groove 2121 and the second groove 2141 are arranged in parallel, and the openings of the first groove 2121 and the second groove 2141 are both facing upward, so that the first rotating shaft 3100 can be inserted into the first groove 2121 and the second groove 2141 from above. To ensure that the first rotating shaft 3100 is placed more firmly in the first groove 2121 and the second groove 2141, a bearing sleeve is provided on one side of the first groove 2121 and the second groove 2141.

[0077] In certain embodiments, as Figure 5 As shown, a first square hole 2150 is further provided between the wing plate 2130 and the main beam 2110 , and the first square hole 2150 leaves enough space for the third connecting plate 2213 on the third frame 2210 to be connected to the main beam 2110 .

[0078] In another embodiment, since the adjustable chain group 4600 suspends the smoke hood assembly 5000, the adjustable chain group 4600 is arranged on one side of the lifting assembly 4000, so that the centers of gravity of the moving assembly 3000, the lifting assembly 4000 and the smoke hood assembly 5000 are not on the same straight line, which will cause an imbalance in the overall center of gravity, and the second frame member 2200 is arranged on one side of the first frame member 2100, the lifting assembly 4000 is arranged below the first frame member 2100 and parallel to the second frame member 2200, and the second frame member 2200 is also not on the same axis as the center of gravity of the lifting assembly 4000 and the moving assembly 3000. This can balance the imbalance in the center of gravity caused by the smoke hood assembly 5000 and the adjustable chain group 4600, and ensure the overall stability of the angle-adjustable movable lifting smoke guide device.

[0079] In another embodiment, the first frame members 2100 are all made of profiles that are machined, calibrated, and then welded, and are assembled and confirmed on site before being firmly welded.

[0084] In another embodiment, the third frame 2210 and the fourth frame 2220 are processed together, and the third frame 2210 and the fourth frame 2220 are both machined from profiles, calibrated and then welded, and the third frame 2210 and the fourth frame 2220 are connected by bolts so that the height of the second frame member 2200 is adjustable.

[0085] like Figure 3As shown, in the specific structure of this embodiment, the lifting assembly 4000 includes a first drive chain 4500 located on both sides; the adjustable chain group 4600 includes a connecting seat 4610 located on both sides, and the connecting seats 4610 on both sides are respectively connected to the left and right ends of the smoke hood assembly 5000, and the connecting seats 4610 are provided with connecting holes; the connecting seats 4610 on both sides are respectively connected to the first drive chains 4500 on both sides by connecting pins passing through the connecting holes, and are located at different heights to adjust the inclination angle of the smoke hood assembly 5000.

[0086] It can be understood that the adjustable chain group 4600 is connected to the first drive chain 4500 on both sides of the lifting assembly 4000 through the connecting seats 4610 on both sides. The first drive chain 4500 and the connecting seat 4610 are both provided with connecting holes.

[0087] like Figure 4 As shown, in the specific structure of this embodiment, the lifting assembly 4000 includes: a second rotating shaft 4100, a second motor 4200, a first sprocket 4300 and a second sprocket 4400; the second rotating shaft 4100 is connected to the frame assembly 2000; the second motor 4200 is arranged on the second rotating shaft 4100; the two first sprockets 4300 are arranged on the second rotating shaft 4100 and are respectively arranged toward the ends of the second rotating shaft 4100; the two second sprockets 4400 are respectively arranged below the two first sprockets 4300; the first drive chain 4500 is connected to the first sprocket 4300 and the second sprocket 4400.

Each shaft support 2160 has a first shaft hole, a first shaft sleeve is disposed within the first shaft hole, and the second shaft 4100 is connected to the first shaft sleeve and rotates within the first shaft hole following the second motor 4200. It is easy to imagine that the shaft support 2160 is welded to the main beam 2110 to provide support for the lifting assembly 4000.

[0091] In another embodiment, a first connecting plate 2111, a first bending plate 2112 and a second bending plate 2113 that are exactly the same as those between the first motor and the main beam 2110 are also provided between the second motor 4200 and the main beam 2110. Their connection structures and functions are exactly the same and will not be elaborated on here.

[0092] In another embodiment, the second motor 4200 also uses the same motor as the first motor 3200, and its deceleration structure and locking structure and function are also exactly the same, which also facilitates the operation and positioning of the lifting assembly 4000, and will not be elaborated here one by one.

[0093] In another embodiment, Figure 2 As shown, a connecting frame 2223 is also provided at the bottom of the fourth frame 2220. The connecting frame 2223 is arranged on the side of the bottom end bracket 2222 facing the lifting assembly 4000. The connecting frame 2223 is fixedly connected to the bottom end bracket 2222. There are two connecting frames 2223, which are respectively used to fix the central axis of the second sprocket 4400 and provide a fulcrum for the second sprocket 4400.

[0094] like Figure 3 As shown, in the specific structure of this embodiment, the adjustable chain group 4600 also includes: a second chain 4620 and a second adjustment rod 4630; the second adjustment rods 4630 are respectively connected to the connecting seats 4610 on both sides, and the second adjustment rods 4630 move in the up and down directions. A second chain 4620 of different lengths is arranged below each second adjustment rod 4630, and the second chains 4620 on both sides are respectively connected to the left and right ends of the smoke hood assembly 5000.

[0095] It is understood that one end of the connecting base 4610 is connected to the first drive chain 4500 and the other end is connected to the second adjustment rod 4630. The second adjustment rod 4630 is connected to the second chain 4620. The second chain 4620 is connected to the smoke hood assembly 5000, driving the smoke hood assembly 5000 to rise or fall. The connecting base 4610 is connected to the first drive chain 4500 via a connecting pin through a connecting hole. There are multiple connecting holes, and the connecting pin can be connected to any of them as needed, facilitating adjustment of different tilt angles. The connecting base 4610 and the connecting pin are connected by bolts. The second adjustment rod 4630 is connected to the connecting base 4610 via a screw. By rotating the screw at the position of the connecting base 4610, the length of the second chain 4620 can be fine-tuned.

[0096] In another embodiment, two of the connecting seat 4610, the second chain 4620 and the second adjusting rod 4630 are respectively provided, which are respectively located in cooperation with the first driving chain 4500 on both sides, driving the smoke hood assembly 5000 to move up and down, and adjusting the angle of the smoke hood assembly 5000.

[0097] In another embodiment, the two second chains 4620 have different lengths. The different lengths of the second chains 4620 allow the smoke hood assembly 5000 to be tilted, and the second chains 4620 are connected to different connecting holes with the connecting pins to adjust the appropriate angle. The adjustable chain group 4600 is connected to the two first drive chains 4500 at different positions respectively through the second adjustment rod 4630 above the two second chains 4620 of different lengths in conjunction with the connecting seat 4610 and the connecting pin, thereby achieving adjustment of the lifting height and angle tilt. The connection of the connecting seat 4610 and the connecting pin to the two first drive chains 4500 at different positions realizes the main adjustment of the height and angle of the smoke hood assembly 5000, and the second adjustment rod 4630 realizes fine-tuning of the height and angle to meet actual production needs.

[0098] It can be understood that the angle adjustment can be achieved according to the angle of the discharge chute of the metal smelting equipment through the adjustable chain group 4600 and the lifting assembly 4000, and the adjustment range can reach 0-20°, so that the smoke hood assembly 5000 can form the best smoke collection angle with the chute and the environmental protection fan smoke collection hood, thereby improving the smoke collection efficiency, effectively improving the working environment of the emission posts in the smelting industry, and reducing low-altitude pollution.

[0099] like Figure 2As shown, in the specific structure of this embodiment, a limiting rod 4700 is further provided between the lifting assembly 4000 and the smoke hood assembly 5000 , and the limiting rod 4700 is connected to the fourth frame 2220 .

[0100] It is understood that when the smoke hood assembly 5000 rises to a certain height, the limiting rod 4700 will limit it to prevent it from rising too high, causing the bottom of the fourth frame 2220 to collide with the top of the smoke hood assembly 5000 and damage the smoke hood assembly 5000. The limiting rod 4700 is connected to the lifting assembly 4000 with bolts and is used to adjust and limit the travel distance of the smoke hood assembly 5000.

[0102] It is understood that the smoke hood assembly 5000 is used to collect and guide flue gas. The flue gas in the metal smelting equipment is discharged through the chute. The smoke hood body 5100 completely encloses the outside of the chute. The chute cooperates with the smoke guide groove 5200 to completely guide the flue gas out of the smoke guide groove 5200. It is easy to imagine that the smoke hood assembly 5000 and the adjustable chain assembly 4600 can be provided with a detachable connection to facilitate cleaning and maintenance of the smoke hood assembly 5000.

[0103] In summary, the present application proposes an angle-adjustable movable lifting smoke guide device, which is provided by setting a track 1000, the frame assembly 2000, and setting the moving assembly 3000 on the frame assembly 2000 and connecting it to the track 1000, so that the frame assembly 2000 is driven by the moving assembly 3000 to move along the track 1000, the lifting assembly 4000 is provided on the frame assembly 2000, and the lifting assembly 4000 is provided with an adjustable chain group 4600; the smoke hood assembly 5000 is provided to be connected to the adjustable chain group 4600, so that the moving assembly 3000 can slide along the track 1000, and the adjustable chain group 4600 is used to adjust the inclination angle of the smoke hood assembly 5000, and the smoke hood assembly 5000 is driven by the lifting group The smoke hood assembly 5000 is driven by the component 4000 to move in the up and down directions, and the moving component 3000 drives the frame component 2000 to slide above the metal smelting equipment that needs to exhaust smoke. The lifting component 4000 moves up and down along the direction of the frame component 2000, and moves the smoke hood assembly 5000 to the smoke exhaust chute close to the metal smelting equipment, and then adjusts the adjustable chain group 4600 according to the inclination angle of the smoke exhaust chute, and adjusts the smoke hood assembly 5000 to an angle suitable for the smoke exhaust chute, so that the smoke hood assembly 5000 completely and tightly covers the smoke exhaust chute to prevent smoke from escaping, and the angle-adjustable movable lifting smoke guide device can be adjusted to match all metal smelting equipment in the smelting area, which solves the problem of poor flexibility in the use of fixed smoke hoods in the prior art because each metal smelting equipment needs to match smoke hoods with different inclination angles.
