Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as figure 1 and 2 As shown, the H-shaped steel powder spraying system includes a powder spraying room 1 with openings at both ends. The powder spraying room is equipped with an electrostatic powder spraying gun 2. The cross-sectional shape of the entrance and exit of the powder spraying room 1 is rectangular. The inner wall is made of spliced stainless steel plates. The bottom of the powder spraying chamber 1 is provided with a powder accumulation box 3 which is open upwards. 21 directional powder blowing nozzles 5 connected to the air supply source are distributed on the bottom wall, the blowing outlet of the powder blowing nozzle 5 faces the powder suction port, and a flame detector with double infrared flame detection is arranged in the powder spraying chamber 1; the powder accumulation box 3 extends horizontally along the le...

The invention relates to profile anti-corrosion treatment equipment, in particular to an H-shaped steel powder spraying system. An existing spraying system has the problems that the powder recycling effect is poor, and potential safety hazards are caused by powder accumulation easily. The invention provides an H-shaped steel powder spraying system which comprises a powder spraying chamber with two open ends, a powder spraying gun arranged in the powder spraying chamber, an open powder accumulation box arranged at the bottom of the powder spraying chamber, a powder pumping opening in butt joint with a powder pumping air pipe arranged at the bottom of the powder accumulation box, a plurality of directional powder blowing nozzles arranged on the bottom wall of the powder accumulation box, and air blowing openings of the nozzles facing the powder pumping opening. According to the spraying system, accumulated powder is specially blown to the powder pumping opening through the powder blowing nozzle so as to clean and recover the accumulated powder attached to the bottom wall of the powder chamber, and potential safety hazards caused by the accumulated powder on the bottom wall are avoided.
Description
technical field [0001] The invention relates to the field of anticorrosion treatment of metal materials, in particular to an H-shaped steel powder spraying system. Background technique [0002] H-shaped steel is commonly used steel, in order to enhance its surface anti-corrosion performance, special anti-corrosion treatment is required. The anti-corrosion treatment of the surface of the section steel adopts special electrostatic powder spraying equipment for spraying processing, and the section steel is translated into a channel-type electrostatic powder spraying room. The installed electrostatic powder spray gun adheres the epoxy powder to the surface of the section steel by electrostatic spraying. During the powder spraying process, powder will fall to the bottom of the powder spray booth. These powders need to be cleaned and recycled to reduce the pollution of the powder to the surrounding environment, improve the utilization rate of the powder and reduce waste. Long-te...
