[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through innovative structural design, significantly improves the operational flexibility and efficiency of the exhaust system in steel structure spraying operations. First, the air inlet mechanism adopts a movable and adjustable design. The air collection hood is connected to the telescopic rod via a mounting base, and its height is infinitely adjustable through the pipe body, threaded rod, and threaded hole. Combined with the movable base and brake casters, the air collection hood can be quickly and accurately positioned near the spraying area of ​​steel structural components of different sizes and shapes, effectively capturing paint mist and harmful gases. The flexible connection structure of the hose and threaded pipe further enhances the system's adaptability. The air inlet hood is connected to the exhaust hood via a flange, ensuring the sealing and stability of the airflow channel. This flexible and adjustable air inlet method overcomes the shortcomings of traditional exhaust equipment, which has a fixed air inlet position and is difficult to adapt to complex working conditions. It greatly improves the efficiency of pollutant collection, ensuring the health of operators and the cleanliness of the spraying environment.

The air filter in the exhaust mechanism integrates a fiber cotton primary filter layer and a HEPA high-efficiency filter, which can intercept large paint mist particles and micron-sized ultrafine particles step by step, achieving deep purification of spraying pollutants and ensuring that the exhaust air meets environmental protection standards. The air filter, exhaust hood, and exhaust pipe are all connected by threads, making disassembly and assembly simple and facilitating regular replacement and maintenance, reducing equipment downtime and maintenance costs. The overall structure is reasonably designed, and the modularity of each component is high, which not only improves the reliability and service life of the system, but also provides strong support for enterprises to achieve green, efficient, and sustainable spraying production.

[0026] Furthermore, the exhaust mechanism 1 includes an exhaust hood 101, inside which a housing 109 is installed, and inside the housing 109 a rotating shaft 111 is rotatably connected, one end of the rotating shaft 111 extending to the outside of the housing 109 and surrounding it with a fan blade 105.

[0027] Furthermore, a motor mount 102 and a protective cover 104 are fixedly connected to the surface of the exhaust hood 101, and a motor 103 is fixedly installed on the motor mount 102.

[0028] Furthermore, the output shaft of the motor 103 extends into the inner cavity of the protective cover 104 and is fitted with a drive pulley 107. The other end of the rotating shaft 111 is fitted with a driven pulley 110. The surfaces of the drive pulley 107 and the driven pulley 110 are connected by a belt 108.

[0029] Furthermore, the exhaust hood 101 is fixedly connected to a support leg 106.

[0030] Furthermore, the air intake mechanism 2 includes a hose 201, one end of which is connected to an air collection hood 211, and the other end of which is connected to a threaded pipe 203, with an air intake hood 202 threadedly connected to the surface of the threaded pipe 203.

[0031] Furthermore, the air inlet hood 202 is installed at one end of the exhaust hood 101 via a flange and is connected to it.

[0032] Furthermore, a mounting base 204 is bolted to the surface of the gas collection hood 211, and a telescopic rod 210 is fixedly connected to the bottom of the mounting base 204.

[0033] Furthermore, a tube body 209 is movably sleeved on the surface of the telescopic rod 210, a movable base 207 is fixedly connected to the bottom of the tube body 209, and a brake caster 208 is fixedly connected to the bottom of the movable base 207.

[0034] Furthermore, the telescopic rod 210 has a threaded hole 205 on its surface, and the tube body 209 has a threaded rod 206 installed on its surface. One end of the threaded rod 206 extends into the threaded hole 205 and is threadedly connected to it.

[0035] Furthermore, the air outlet mechanism 3 includes an air filter element 301, one end of which is threadedly connected to an air outlet cover 303, and the other end of which is threadedly connected to an air outlet pipe 302.

[0036] Furthermore, the air outlet hood 303 is installed at the other end of the exhaust hood 101 via a flange and is connected to it.

[0037] When exhausting polluted air during the spraying process, the air collection hood 211 is first flexibly adjusted to the vicinity of the spraying point using the mounting base 204 and telescopic rod 210 to directly adsorb harmful substances such as paint mist and solvent vapor. The height is adjusted using the threaded hole 205 and threaded rod 206 of the telescopic rod 210, and the position of the air collection hood 211 is quickly moved and fixed by the movable base 207 and brake casters 208, ensuring flexible and efficient capture of pollutants. After adjustment, the pollutants captured by the air collection hood 211 are transported to the threaded pipe 203 through the hose 201, and then enter the exhaust hood 101 through the threaded connection. The air inlet hood 202 is connected to the exhaust hood 101 through the flange to ensure no leakage in the airflow path and improve transmission efficiency.

[0038] The motor 103 drives the rotating shaft 111 to rotate via the active pulley 107, belt 108, and driven pulley 110, which in turn drives the fan blades 105 to rotate at high speed. The fan blades 105 generate negative pressure airflow, which accelerates the pollutants to the other end of the exhaust hood 101 and then enters the air filter 301 through the exhaust hood 101 and the air outlet hood 303. The air filter 301 is equipped with a primary filter layer made of fiber cotton to intercept large particles of paint mist, and also has a HEPA filter to capture ultrafine particles. The purified air is discharged to the outside of the workshop or into the air purification equipment through the air outlet duct 302 to ensure that the emissions meet the standards.

[0039] The air filter element 301 adopts a threaded connection design, which is easy to disassemble and replace, reducing maintenance costs. The air intake mechanism 2 is moved by the brake caster 208, and the height of the air collection hood 211 is adjusted by the telescopic rod 210, which can quickly adapt to the spraying needs of steel structural parts of different sizes and shapes.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
