A material guide device is provided above the dust suction port to connect the dust removal device with the steel plant's dust removal system. When the scrap steel trough is loaded, the material is guided into the scrap steel trough by the material guide device to prevent the material from falling to the ground, which is difficult to clean up. The raised dust enters the dust removal pipe through the dust suction port and then enters the dust removal system. The dust removal device has a simple structure and is easy to operate.

[0030] Example 1:

[0031] Reference Figure 1 and Figure 2, which is an airborne intelligent dust removal equipment disclosed in the utility model, includes a cutting car 1 and a cutting gun trolley 2, a dust removal pipe 3, a dust removal pipe lifting mechanism 4, and a dust collector 5 arranged on the cutting car 1. The cutting gun trolley 2 is used to cut the scrap steel billet under the cutting car 1. The dust removal pipe 3 is connected to the dust collector 5. The dust removal pipe 3 is installed on the dust removal pipe lifting mechanism 4. The dust removal pipe lifting mechanism 4 is used to drive the dust removal pipe 3 to rise and fall. A dust removal port adjustment mechanism 6 is installed on the dust removal pipe 3. The dust removal port adjustment mechanism 6 is used to adjust the opening and closing of multiple suction zones on the dust removal pipe 3.

[0032] Reference Figure 3 The dust removal pipe lifting mechanism 4 is configured as two, and the two dust removal pipe lifting mechanisms 4 are symmetrically arranged on the brackets 11 on both sides of the cutting vehicle 1. The two sides of the dust removal pipe 3 are respectively connected to the two dust removal pipe lifting mechanisms 4, and the dust removal pipe 3 is located below the main body of the cutting vehicle 1.

[0033] Reference Figure 3 The dust removal duct lifting mechanism 4 includes a transmission motor 41, a screw 42, and a lifting guide wheel 43. A lifting seat 44 is fixed to each end of the dust removal duct 3. The lifting guide wheel 43 is mounted on one side of the lifting seat 44. A lifting guide slot 45 is provided on the inner side of the bracket 11 for the lifting guide wheel 43 to slide. The transmission motor 41 is arranged at the bottom of the bracket 11. One end of the screw 42 is coaxially fixed to the output shaft of the transmission motor 41, and the other end of the screw 42 is in transmission connection with the lifting seat 44. The transmission motors 41 on both sides drive the screw 42, causing the lifting guide wheel 43 to move up and down in the lifting guide slot 45, thereby driving the air intake port to move up and down.

[0034] Reference Figure 4 and Figure 5 The dust removal duct 3 includes a curved duct 31, a connecting duct 32, and a suction duct 33, which are connected in sequence. One end of the curved duct 31 is connected to the dust collector 5. The suction duct 33 is provided with three suction zones that communicate with the interior of the connecting duct 32. The connection port at one end of the curved duct 31 is connected to the lower end of the dust collector 5. The suction ports of the suction zones, through the negative pressure of the duct, suck the external cutting dust into the dust removal duct 3 and into the dust collector 5, thereby achieving the purpose of dust removal.

[0035] Reference Figure 6 Adjustable sealing plates 7 are rotatably installed in the suction ducts 33 between two adjacent suction zones. A dust removal port adjustment mechanism 6 is transmission-connected to the two adjustment sealing plates 7 and is used to drive the adjustment sealing plates 7 to rotate. The dust removal port adjustment mechanism 6 includes a base 61, a cylinder 62, a transmission frame 63, two first connecting rods 64, two second connecting rods 65, and two rotating shafts 66. The base 61 is detachably fixed to the suction duct 33, and the cylinder 62 is detachably fixed to the base 61.

[0036] Reference Figure 4 The transmission frame 63 is detachably fixed to one end of the piston rod of the cylinder 62. One end of each of the two first connecting rods 64 is hingedly connected to the transmission frame 63, and the other end is hingedly connected to the two second connecting rods 65. Two rotating shafts 66 are rotatably arranged inside the suction duct 33. One end of each of the two rotating shafts 66 is fixed to the end of the two second connecting rods 65 away from the first connecting rod 64. The adjustment cover 7 is detachably fixed to the rotating shafts 66. The cylinder 62 pushes the first connecting rod 64, which drives the second connecting rod 65 to rotate. The rotating shafts 66 are driven to rotate by the linkage mechanism, thereby driving the rotation of the adjustment cover 7.

[0037] When the two adjustable sealing plates 7 are rotated to a horizontal position, the suction zone at the bottom center of the suction duct 33 is closed and has no negative pressure, while the suction zones on either side are open and have negative pressure. When the two adjustable sealing plates 7 are rotated to a vertical position, the suction zone at the bottom center of the suction duct 33 is open and has negative pressure, while the suction zones on either side are closed and have no negative pressure. A cutting gun 21 for cutting scrap steel billets is mounted at each end of the cutting gun carriage 2. An encoder is mounted on the driving carriage for the cutting gun 21 to detect the position of the cutting gun 21 in real time.

[0038] Working principle: First, the dust removal duct 3 is raised to the top by the dust removal duct lifting mechanism 4 to prevent the dust removal duct 3 from hitting the scrap steel billet during movement. Then, the cutting gun trolley 2 and the dust collector 5 are moved as a whole to the top of the scrap steel billet. After the thickness of the steel billet is detected, the dust removal duct lifting mechanism 4 is used to automatically lower the air suction port to an appropriate height, and the two cutting guns 21 perform relative cutting. The cutting gun trolley 2 is equipped with an encoder to detect the position of the cutting gun 21 in real time. When the two cutting guns 21 are cutting in the suction areas 1 and 3 at both ends, the dust removal port adjustment mechanism 6 will close the suction port of the suction area 2 by adjusting the sealing plate 7. At this time, there is negative pressure in the suction area 1 and the suction area 3, and there is no negative pressure in the suction area 2; when the two cutting guns 21 move to the middle suction area 2 for cutting, the dust removal port adjustment mechanism 6 will open the suction port of the suction area 2 by adjusting the sealing plate 7, and at the same time close the suction area 1 and the suction area 3. At this time, there is no negative pressure in the suction area 1 and the suction area 3, and there is negative pressure in the suction area 2, thereby achieving the purpose of dust removal.

[0039] The implementation principle of the present utility model is as follows: the present utility model discloses an airborne intelligent dust removal device. Compared with the existing dust removal equipment, it can not only move together with the cutting vehicle 1 according to the cutting position of the scrap steel while cutting the scrap steel, but also lift and lower the dust removal pipe 3 according to the thickness of the scrap steel, so as to be as close to the scrap steel billet as possible. In addition, the pipe opening in the dust removal pipe 3 can also be adjusted according to the cutting position of the cutting gun 21, so as to better collect the smoke and dust, improve the dust removal effect, and thus achieve the purpose of collecting the smoke and dust.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
