Description

Technical Field

[0001] The utility model relates to the technical field of steel cutting auxiliary equipment, in particular to a mobile slab cutting automatic dust collection device. Background Technique

[0002] A slab is a type of steel billet formed by continuous casting of molten steel. Generally, a casting billet with a width-thickness ratio greater than 3 is called a slab, which is mainly used for rolling sheets but has not started rolling yet.

[0003] After continuous casting of the slab, it is necessary to cut the slab into different length dimensions according to requirements by using a flame cutting machine. When the flame cutting machine cuts the slab, a large amount of soot and toxic and harmful gases generated by incomplete combustion of natural gas will be produced. Usually, a dust removal hood is made to suck out the soot and toxic gases.

[0004] However, the cast slab is constantly moving. To ensure a smooth cut of the slab, the flame cutting machine also needs to move at the same speed as the slab, so that the cutting part generating soot changes and moves continuously.

[0005] Moreover, the usually used dust removal device is fixed. The movement of the cutting position makes the fixed dust removal device unable to effectively suck the generated dust into the dust removal pipeline, causing the production site to be filled with soot, and the toxic gases will also affect the health of on-site workers. Moreover, it often requires personnel to clean, wasting manpower and material resources.

[0006] To solve the above problems, the utility model provides a mobile slab cutting automatic dust collection device. Content of the Utility Model

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] A mobile slab cutting automatic dust suction device, as Figure 1 and Figure 2 shown, includes a slab 1, a flame cutting machine 2, and a dust removal hood 3 provided on the flame cutting machine 2. The dust removal hood 3 is movably connected above the slab 1 through a moving mechanism 4; the moving mechanism 4 includes a base 41, a track 42, a moving trolley 43, a ventilation duct 44, a main dust removal pipe 5, and a driving member 6.

[0032] Wherein, the base 41 is arranged in parallel on one side of the slab 1; the track 42 is integrally connected to the base 41; the bottom of the moving trolley 43 is movably connected to the track 42, and the dust removal hood 3 communicates with the moving trolley 43; the ventilation duct 44 is arranged on the base 41, and the moving trolley 43 is located above the ventilation duct 44 for discharging the dust sucked by the dust removal hood 3 into the ventilation duct 44; the main dust removal pipe 5 communicates with the side of the ventilation duct 44 for discharging the dust; the driving member 6 is arranged on the base 41 for driving the moving trolley 43 and the dust removal hood 3 to move.

[0033] In the present invention, the driving member 6 includes motors 61 and reels 62 arranged at both ends of the base 41. A belt 63 is wound around the two reels 62. The belt 63 is connected to the moving trolley 43 and covers and seals the ventilation duct 44. To ensure quality and use safety, the belt 63 is a high-temperature resistant belt 63.

[0034] As Figure 1 and Figure 2 shown, the dust removal hood 3 communicates with the moving trolley 43 through a dust removal pipe 51, and the dust removal pipe 51 leads into the ventilation duct 44. A plurality of roller tables 7 are arranged at the bottom of the slab 1. The slab 1 is placed on the roller tables 7, and the moving trolley 43 is connected to the track 42 through running wheels 8.

[0035] To reduce the possibility of equipment damage, the utility model controls the synchronous movement of the mobile trolley 43, the dust removal hood 3 and the flame cutting machine 2 through computer operation of the PLC, ensuring that the moving speeds and directions of the three correspond, and also improving the automation degree of the equipment.

[0036] When the utility model is in use, according to the speeds of the slab 1 and the flame cutting machine 2 in daily production, the farthest walking distance of the flame cutting machine 2 is calculated. A bracket 9 is erected at the edge of the conveying roller path 7 of the slab 1, and a ventilation groove 44 is made and installed above the bracket 9. The length of the ventilation groove 44 is the same as the running distance of the flame cutting machine 2, and the ventilation groove 44 is connected to the dust removal main pipe 5.

[0037] When the flame cutting machine 2 moves, it will drive the mobile trolley 43 to move synchronously. The dust generated by the flame cutting machine 2 will be absorbed by the dust removal hood 3 fixed on the flame cutting machine 2, and then enter the mobile trolley 43 through a pipeline. The dust will be discharged into the ventilation groove 44 through the ventilation opening under the mobile trolley 43. The ventilation groove 44 is connected to the dust removal main pipe 5, and the dust will be sucked into the interior of the dust removal main pipe 5.

[0038] A reel 62 is installed at each end of the ventilation groove 44. A high-temperature resistant belt 63 wrapped around the reel 62 is connected to the mobile trolley 43. When the mobile trolley 43 moves, the belt 63 will cover the ventilation groove 44 to seal the ventilation groove 44, only leaving the contact part between the ventilation opening of the mobile trolley 43 and the ventilation groove 44. This can avoid the dispersion of the wind force in the dust removal main pipe 5, completely suck out the dust generated by cutting, avoid affecting the on-site construction environment, and reduce the working intensity of the staff to clean the site.

[0039] The reel 62 on the ventilation groove 44 is controlled to rotate by a motor 61. The motor 61, the flame cutting machine 2 and the speed of the slab 1 form an interlock. An operator issues a speed signal of the slab 1 through a computer. The signal is transmitted to the PLC and then respectively transmitted to the flame cutting machine 2 and the motor 61 of the reel 62, so as to ensure that the rotation speed of the motor 61 of the reel 62, the marching speed of the slab 1 and the speed of the flame cutting machine 2 are consistent, avoiding equipment damage caused by non-synchronization.

[0040] Specific operation steps: The operator sets the running speed of the slab 1 according to the production requirements through the computer. This signal is transmitted to the PLC, and then the PLC transmits the signal to the motor 61 of the reel 62, the flame cutting machine 2, and the transport mechanism of the slab 1 respectively. While the slab 1 is moving, the flame cutting machine 2 moves at the same speed. The dust and toxic gases generated by the flame cutting of the slab 1 are absorbed by the dust removal hood 3 fixed on the flame cutting machine 2, and are transported to the ventilation opening of the mobile trolley 43 through the dust removal pipe 51. The dust is discharged into the ventilation trough 44 through the ventilation opening, and then the dust is sucked in by the wind force of the main dust removal pipe 5. During the process, the motors 61 of the reels 62 at both ends of the ventilation trough 44 will rotate at a fixed speed according to the signal transmitted by the PLC, so that the high-temperature resistant belt 63 covers the ventilation trough 44, and only the contact part between the ventilation opening of the mobile trolley 43 and the ventilation trough 44 is reserved to ensure the sealing effect and avoid the dispersion of wind force.
