[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] 1) Transportation by transportation mechanism: I-beams enter the sandblasting area from the feed port of the processing bin through the transportation mechanism;

[0010] 2) Shot blasting mechanism: Motor II drives the worm to rotate, driving the worm wheel meshing with it to rotate, so that the lead screw I rotates, and the sliding frame II moves under the action of the lead screw I. The motor IV drives the worm to rotate, driving the worm wheel on the bidirectional lead screw to rotate, so that the clamp slides in the rotating shell to clamp the I-beam horizontally. The motor III drives the rotating shell to rotate, thereby driving the I-beam to rotate; the nozzle I at the bottom of the raw material box I sprays metal projectiles to sandblast the I-beam;

[0011] 3) Sandblasting dust collection: The slag suction port on the sliding frame I frame collects the dust during sandblasting and transports it to the purification treatment mechanism. After completion, the transportation mechanism transports the I-beam to the flipping mechanism;

[0012] 4) Flipping of the flipping mechanism: Motor VI rotates the lead screw II through the bevel gear transmission, thereby driving the sliding frame III to move in the sliding groove II to adjust the clamping position of the limit plate; at the same time, the cylinder III drives the sliding block I to move, so that the rotating block rotates, and then drives the rotating shaft III to rotate, prompting the limit plate to rotate to clamp the I-beam; then the double-acting cylinder at the output connection end of the first group of rotating shafts II contracts, so that the flipping frame of the first group of rotating shafts II rotates 90° to face the flipping frame of the second group of rotating shafts II; the cylinder III drives the sliding block I to move, so that the rotating block rotates; the cylinder II drives the top plate II to push the I-beam onto the flipping frame of the second group of rotating shafts II;

[0013] 5) Spraying by spraying mechanism: Motor VII drives the spray hood to slide in the processing chamber to cover the area to be sprayed; during the spraying process, the paint is transported from the raw material box II to the hose through the pipeline, and the paint is transported to the telescopic nozzle to spray the I-beam;

[0014] 6) Drying with dryer: After spraying is completed, motor VIII drives rotating shaft IV, and the rotating baffle rotates close to the telescopic nozzle through bevel gear transmission. The dryer dries the sprayed I-beam in time through air pipe I and drying hot air outlet, and then repeats steps 4) to 6) until the spraying and drying of the I-beam is completed;

[0015] 7) Waste gas collection: The generated waste gas is first guided to the collection tank on the fixed frame III, and the waste gas is initially filtered through the filter plate to remove the paint mist particles and impurities. At the same time, the motor Ⅺ drives the lead screw IV to rotate, driving the cleaning component to move on the filter plate to clean the accumulated impurities and ensure the filtering effect; the waste gas after the initial filtration enters the trachea IV through the trachea II and trachea III, and is finally extracted by the vacuum pump and sent to the low-temperature plasma treatment box for further treatment to meet the emission standards;

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1) When sandblasting the steel structure surface, the rust dust and metal debris generated during sandblasting are collected to prevent dust pollution. The waste gas generated during spraying is also recovered and treated in time to prevent the overflow and diffusion of organic waste gas. While greatly reducing the environmental pollution of organic waste gas, the efficiency of steel structure surface treatment and waste gas purification of the device is improved;

[0025] 2) Motor II drives the worm to rotate, so that the lead screw I rotates, and the sliding frame II moves under the action of the lead screw I. The motor IV drives the worm to rotate, which drives the worm wheel on the bidirectional lead screw to rotate, so that the clamp slides in the rotating shell to clamp the I-beam horizontally. The motor III drives the rotating shell to rotate, thereby driving the I-beam to rotate; the nozzle I at the bottom of the raw material box I sprays metal projectiles to sandblast the I-beam; through the precise coordination of the motor-driven worm, worm wheel and lead screw, all-round and precise sandblasting of the I-beam is achieved, which significantly improves the efficiency and quality of sandblasting; the slag suction port on the sliding frame I frame collects the dust generated by sandblasting when the shot blasting mechanism is sandblasting and transports it to the purification treatment mechanism; during the process of the shot blasting mechanism sandblasting the I-beam, the slag suction port can collect the dust generated during the sandblasting process in real time and efficiently, effectively avoiding the accumulation of dust in the working area, while ensuring the cleanliness and safety of the working environment, avoiding dust pollution to the environment;

[0026] 3) Motor Ⅶ drives the spray hood to slide downward in the processing chamber. The inner diameter of the spray hood matches the inner diameter of the collection tank, and the positions of the spray hood and the collection tank correspond. When the spray hood fits with the fixed frame III, the spray hood and the collection tank form a closed spraying space. When the I-beam is sprayed in the spray hood, the exhaust gas generated is first guided to the collection tank on the fixed frame III. The exhaust gas is initially filtered through the filter plate to remove the paint mist particles and impurities. At the same time, motor Ⅺ drives the screw IV to rotate, driving The cleaning component moves on the filter plate to clean the accumulated impurities and ensure the filtering effect; the waste gas after preliminary filtration enters the trachea IV through the trachea II and trachea III, and is finally extracted by the vacuum pump and sent to the low-temperature plasma treatment box for effective purification treatment; the matching design of the inner diameter of the spray hood and the inner diameter of the collection tank ensures the airtightness of the spraying space, so that the waste gas generated by the I-beam during the spraying process can be effectively guided to the collection tank, which improves the efficiency of waste gas collection and avoids the pollution of the environment caused by the overflow of organic waste gas;

[0027] 4) When the spray hood is fitted with the fixed frame III, and the spray hood and the collection tank form a closed spraying space, the support end of the flip frame is located in the spraying space, and the clamping end of the flip frame is located outside the spraying space, which can prevent the paint sprayed from the telescopic nozzle from directly contacting the clamping end during the spraying process; after the spraying mechanism completes spraying in the spraying space, the dryer quickly dries the painted I-beam surface; the closed spraying space provides a stable environment for spraying, ensuring that the paint is evenly attached to the surface of the I-beam, improving the spraying quality, and reducing the pollution of the environment by organic waste gas produced by the volatilization of the paint; secondly, drying immediately after spraying shortens the production cycle and improves production efficiency, while preventing the paint on the surface of the I-beam from drying and causing flow marks when the flip mechanism flips the I-beam, and effectively prevents the paint on the surface of the I-beam from contaminating the clamping end of the flip frame, thereby ensuring the cleanliness of the flip frame and reducing the frequency and cost of maintenance of the clamping end of the flip frame;

[0028] 5) Motor VII drives the spray hood to slide in the processing chamber to cover the area that needs to be sprayed; during the spraying process, the paint is transported from the raw material box II to the hose through the pipeline, and the paint is transported to the telescopic nozzle to spray the I-beam. At the same time, motor VIII drives the rotating shaft IV, and the rotating baffle is rotated close to the drying hot air outlet through the bevel gear transmission, so as to prevent the paint mist from overflowing to the drying hot air outlet and blocking the air duct, and at the same time, maximize the spraying range of the telescopic nozzle; after the spraying is completed, motor VIII drives the rotating shaft IV, and the rotating baffle is rotated close to the telescopic nozzle through the bevel gear transmission, so as to prevent the paint on the telescopic nozzle from being dried and causing the telescopic nozzle to be blocked, and at the same time, maximize the drying hot air range of the drying hot air outlet; further, the dryer promptly dries the I-beam after spraying through the air pipe I and the drying hot air outlet;

[0029] 6) After spraying is completed, motor VI rotates lead screw II through bevel gear transmission, thereby driving sliding frame III to move in sliding groove II to adjust the clamping position of the limit plate; it can be flexibly adjusted according to I-beams of different sizes to adapt to spraying operations of I-beams of various specifications, thereby improving the versatility of the equipment; at the same time, cylinder III drives sliding block I to move, causing the rotating block to rotate, thereby driving rotating shaft III to rotate, causing the limit plate to rotate to clamp the I-beam to prevent the I-beam from slipping during the flipping process.
