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 pipeline 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. The existing dust removal system can solve the dust problem at the receiving point, save costs, and improve the workplace environment.

[0030] Embodiment 1:

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

[0032] Reference Figure 3 The dust removal duct lifting mechanism 4 is configured as two, and the two dust removal duct 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 duct 3 are respectively connected to the two dust removal duct lifting mechanisms 4, and the dust removal duct 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 rod 42 and a lifting guide wheel 43. Lifting seats 44 are fixed at both ends of the dust removal duct 3. The lifting guide wheel 43 is installed on one side of the lifting seat 44. A lifting guide groove 45 for sliding the lifting guide wheel 43 is provided on the inner side of the bracket 11. The transmission motor 41 is arranged at the bottom of the bracket 11. One end of the screw rod 42 is coaxially fixed on the output shaft of the transmission motor 41, and the other end of the screw rod 42 is connected to the lifting seat 44. The transmission motors 41 on both sides drive the screw rod 42, so that the lifting guide wheel 43 moves up and down in the lifting guide groove 45, thereby driving the air suction 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 which are connected to the inside of the connecting duct 32. The connecting port at one end of the curved duct 31 is connected to the lower end of the dust collector 5. The suction port of the suction zone sucks the external cutting dust into the dust removal duct 3 to the dust collector 5 through the negative pressure of the duct, thereby achieving the purpose of dust removal.

[0035] Reference Figure 6 , the air suction duct 33 between two adjacent air suction areas is respectively provided with an adjustable sealing plate 7 for rotation, and the dust removal port adjusting mechanism 6 is transmission-connected with the two adjustable sealing plates 7, and the dust removal port adjusting mechanism 6 is used to drive the adjustable sealing plates 7 to rotate. The dust removal port adjusting 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 on the air suction duct 33, and the cylinder 62 is detachably fixed on 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 the two first connecting rods 64 is respectively hingedly connected to the transmission frame 63, and the other end is respectively hingedly connected to the two second connecting rods 65, two rotating shafts 66 are respectively rotatably arranged inside the air suction duct 33, one end of the two rotating shafts 66 is respectively fixed to one end of the two second connecting rods 65 away from the first connecting rod 64, and the adjustment sealing plate 7 is detachably fixed to the rotating shaft 66. The first connecting rod 64 is pushed by the cylinder 62, and the first connecting rod 64 drives the second connecting rod 65 to rotate, and the rotating shaft 66 is driven to rotate through the connecting rod mechanism, thereby driving the rotation of the adjustment sealing plate 7.

[0037] When the two adjustment sealing plates 7 are rotated to a horizontal state, the suction area in the middle of the bottom of the suction duct 33 is closed and has no negative pressure, and the suction areas on both sides are opened and have negative pressure; when the two adjustment sealing plates 7 are rotated to a vertical state, the suction area in the middle of the bottom of the suction duct 33 is opened and has negative pressure, and the suction areas on both sides are closed and have no negative pressure. Cutting guns 21 for cutting scrap steel billets are respectively installed at both ends of the cutting gun trolley 2. An encoder is installed on the transmission trolley of the cutting gun 21, and the encoder is used 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 area 1 and the suction area 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 invention is as follows: the present invention 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 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.
