[0002] The most common hot processing technology in the shipbuilding industry is welding, which refers to the processing technology of local heating and bonding of metals. A large amount of smoke and toxic and harmful gases are generated during welding. The main component of the smoke is iron and manganese metal oxides, with a particle diameter of 0.1-1.25 microns, which is respiratory dust that can cause pneumoconiosis and cause great and irreversible harm to the human body. At the same time, the smoke generated during welding can cause long-term damage to the atmospheric environment. The existing mobile welding smoke collection and purification device has limited smoke collection area, limited smoke suction power, and poor smoke suction effect, often resulting in smoke overflow and pollution.

Detailed Implementation
[0011] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention.
[0012] like Figures 1 to 4 This invention includes a fumigation mechanism, an escape prevention mechanism, and a frame 1. The escape prevention mechanism is located below the fumigation mechanism, and both the fumigation mechanism and the escape prevention mechanism are fixed to the frame 1. The escape prevention mechanism includes a rectangular support frame 2, jet nozzles 3, and an air intake component. The support frame 2 is located below the fumigation mechanism, the jet nozzles 3 are evenly installed on the top of the support frame 2, and the air intake component is located around the fumigation mechanism. The shape of the air intake component matches the support frame 2, and the area enclosed by the support frame 2 is the working area. The jet nozzles 3 on the support frame 2 simultaneously spray gas, and the air curtain is drawn away by the air intake component at the top, forming an air curtain. During operation, welding operations are performed in the working area, and the resulting welding fumes are drawn away by the fumigation mechanism. The escape prevention mechanism can reduce the outward diffusion of fumes near the support frame 2. At the same time, as the fumes move upward, they diffuse around, and the air curtain can reduce the diffusion of upper-layer fumes out of the working area. To facilitate movement and adapt to different work requirements, casters 21 are provided at the bottom of the frame 1.
[0013] See Figure 4 The jet head 3 includes a jet nozzle 4, a high-pressure air source 5, a main air supply pipe 6, and a branch air supply pipe 7. The main air supply pipe 6 is connected to the outlet end of the high-pressure air source 5. The jet nozzle 4 and the main air supply pipe 6 are connected through the branch air supply pipe 7, and a valve is installed on the branch air supply pipe 7. The valve can adjust the airflow of the jet head 3 to form a stable air curtain and reduce flue gas overflow.
[0014] See Figure 2 The smoking components include a smoke hood 8, a smoke machine 9, and a smoke pipe 10. The smoke hood 8 is located directly above the work area, and its top has a vent 11. The vent 11 is connected to the smoke machine 9 via the smoke pipe 10 to draw away smoke from the upright work area. A smoke filter cartridge 12 is also provided between the smoke machine 9 and the smoke hood 8 to filter the smoke in a timely manner, and then the treated air can be discharged promptly.
[0015] Furthermore, to maintain the stability of the air curtain and prevent the airflow from the jet head 3 from diverging when it reaches the large intake component, an airflow protection mechanism is also provided, see [link / reference]. Figure 3 and Figure 4The airflow protection mechanism includes a base 13, a spiral air hole 14, and an air supply pipe 15. The spiral air hole 14 is located on the base 13, and the jet head 3 is installed in the middle of the spiral air hole 14. The opening of the spiral air hole 14 faces upward. The bottom of the base 13 is provided with an air inlet 16. The spiral air hole 14 and the air supply pipe 15 are connected through the air inlet 16. The air supply pipe 15 is connected to the main air supply pipe 6. The inner wall of the spiral air hole 14 is provided with a spirally upward guide groove, which allows the airflow to form a spiral airflow when it exits the spiral air hole 14. The airflow ejected by the jet head 3 rises together in the middle of the spiral airflow and is eventually sucked away by the suction hood 17, which can slow down the dispersion of the airflow ejected by the jet head 3 and ensure the integrity and sealing of the air curtain. A blower 20 is added to the air supply pipe 15. See Figure 2 The suction component includes a suction hood 17 and a suction pipe 18. The suction hood 17 is located outside the smoke hood 8 and above the support frame 2. The shape of the suction hood 17 matches the shape of the support frame 2. One end of the suction pipe 18 is connected to the top of the suction hood 17, and the other end is connected to the air inlet of the smoke filter cartridge. This allows the air curtain to be drawn upwards, ensuring that the airflow direction is upward and reducing smoke overflow. To ensure sufficient suction power, an induced draft fan 19 is added to the suction pipe 18.
[0016] During operation, the device is moved to a convenient position, and the valve on the gas supply branch pipe 7 is adjusted to make the air flow rate of the jet nozzle 4 smaller than that of the spiral air hole 14. Welding operations are performed within the work area, and the resulting welding fumes are drawn away by the fume extraction mechanism. Simultaneously, the spiral airflow from the spiral air hole 14 and the straight airflow from the jet nozzle 4 rise together and are ultimately drawn away by the suction hood 17. The escape prevention mechanism reduces the outward diffusion of fumes near the support frame 2. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
