Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection dust removal, and more specifically, to a mobile dust removal device for flame cutting of steel billets. Background Art

[0002] With the upgrading and transformation of the steel industry, the prevention and control of environmental pollution has become increasingly important. The country's requirements for environmental protection are constantly increasing, and ultra-low emission transformation is also being fully rolled out in the steel industry. However, the billets produced by molten steel in steel enterprises need to be flame-cut into semi-finished products of varying specifications and lengths before entering the next process for rolling. However, a lot of smoke and dust is generated during the billet cutting process. The smoke and dust is a mixture of gas and solid particles, which is a common and extremely harmful occupational hazard factor. Its main components are metals, non-metallic oxides, fluorides, etc. The insoluble substances in these components can easily cause pneumoconiosis if inhaled for a long time, causing great harm to workers. Therefore, the smoke and dust generated by flame cutting not only pollutes the environment, but also causes damage to the operator's body.

[0003] The most widely used dust removal methods for steel billet flame cutting in the prior art generally use water mist dust suppression and a dust hood above the flame cutting machine. However, these two methods still have some defects, as follows: 1. Water mist dust suppression cannot completely suppress smoke and dust, resulting in smoke diffusion; 2. The dust hood above the flame cutting machine has a poor dust removal effect and cannot capture all the smoke and dust. In addition, the fixed dust hood needs to be disassembled for maintenance, which makes maintenance difficult. Therefore, it is urgent to develop and design a new type of steel billet flame cutting dust removal device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a mobile dust removal device for flame cutting of steel billets in view of the above-mentioned deficiencies in the prior art, so as to improve the dust removal efficiency, improve the workshop environment and reduce the damage to the health of the operators.

[0005] The technical solution of the utility model is as follows: a mobile dust removal device for flame cutting of steel billets, comprising a dust removal frame, a dust removal hood is provided on the dust removal frame, the dust removal hood is located above the flame cutting machine, a suction pipe connected to the dust removal hood is provided on the top of the dust removal hood, a fan is provided in the suction pipe, a bag dust collector connected to the suction pipe is provided at the outlet end of the suction pipe, walking beams are provided at the bottom of both sides of the dust removal frame, one of the walking beams is provided with a driving device for moving the dust removal hood, the bottom of each of the walking beams is movably connected to a track beam, and the bottom of each of the track beams is provided with a plurality of beam columns.

[0006] As a further improvement, a suction pipe bracket is provided on one side of the dust removal frame, and the top of the suction pipe bracket is connected to the outer wall of the suction pipe.

[0007] Furthermore, the air suction pipe between the fan and the bag filter is a nylon cloth ventilation hose.

[0008] Furthermore, a plurality of wheels are rotatably mounted at the bottom of each walking beam, a track is provided at the top of each track beam, a plurality of wheels are rotatably arranged on the track in a one-to-one correspondence, and a rotating shaft of one of the wheels is connected to the output end of the driving device.

[0009] Furthermore, both ends of each track beam are provided with a limit block, and one side of the limit block is provided with an arc groove adapted to the arc of the wheel.

[0010] Furthermore, the driving device includes a motor and a reduction box. The motor is installed at one end of the top of the walking beam, and the output end of the motor is transmission-connected to the rotating shaft of the wheel through the reduction box.

[0011] Furthermore, the two beams close to the flame cutting machine are provided with sealing plates, the sealing plates are "U" shaped, and the tops of the sealing plates are connected to the track beams.

[0012] Beneficial Effects

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model is a mobile dust removal device for flame cutting of steel billets. An integrally movable dust removal hood is arranged above a flame cutting machine to remove the smoke generated by cutting.
