[0002] The parallel dust explosion-proof cabinet is a safety control electrical cabinet used in combustible dust environments. Through structural design, explosion-proof materials and monitoring systems, it can effectively reduce the risk of dust explosions and ensure production safety.

[0003] The Chinese utility model with announcement number CN220628657U proposes a high-efficiency heat-dissipating dust-proof explosion-proof cabinet, including a shell, the shell including a base frame, the upper surface of the base frame is fixedly connected to the cabinet body, and the inner side of the cabinet is provided with a heat dissipation mechanism, the heat dissipation mechanism includes an air inlet, the air inlet is opened on the inner side of the cabinet body, and the inner wall of the air inlet is fixedly connected to a filter.

[0004] The above technical solution can realize that the moving block can drive the cleaning brush to move its position under the action of the screw through the rotation of the screw.

[0031] In this embodiment, fixing columns 16 are symmetrically provided on both sides of the bottom end of the explosion-proof cabinet 6, and the bottom ends of the fixing columns 16 are fixedly provided inside the bottom end of the outer cabinet 1, and the fixing columns 16 are provided on the inner side of the second filter 15. Vertical plates 7 are fixedly provided on the inner walls of the outer cabinet 1 corresponding to the top sides of the explosion-proof cabinet 6, and a fixing block 8 is fixedly provided between the top of the explosion-proof cabinet 6 and the outer cabinet 1. Ventilation holes 9 are provided inside the explosion-proof cabinet 6 and the vertical plates 7. A cabinet door 2 is movably installed on the front side of the outer cabinet 1 through a hinge, a sealing gasket is provided between the cabinet door 2 and the outer cabinet 1, and a lock is provided between one end of the cabinet door 2 and the outer cabinet 1. The explosion-proof performance of the electrical cabinet can be improved by means of the fixing columns 16, the vertical plates 7, the fixing blocks 8 and the explosion-proof cabinet 6, and the heat inside the explosion-proof cabinet 6 can be discharged through the provided ventilation holes 9, which is convenient for heat dissipation of the electrical equipment inside it.

[0032] In this embodiment, a through hole is opened between the bottom end of the explosion-proof cabinet 6 and the air inlet 3, and the mounting mechanism includes a square frame 17, which is fixedly arranged at the bottom of the through hole, and a second servo motor 23 is fixedly arranged on the outer wall of the square frame 17. An adjustment frame 18 is movably provided inside the square frame 17 through a rotating rod, and a fan 19 is fixedly provided inside the adjusting frame 18. The fan 19 is arranged below the through hole, and the rotating rod is symmetrically fixed with both ends of the adjusting frame 18. The output shaft of the second servo motor 23 is fixedly connected to one end of one of the rotating rods. The adjusting frame 18 and the fan 19 can be rotated and adjusted by the second servo motor 23, thereby changing the wind direction of the fan 19, making it convenient to remove the dust cleaned on the first filter 14 and the second filter 15, and prevent it from continuing to adhere to the surface of the first filter 14 and the second filter 15 and affecting the heat dissipation of the electrical cabinet.

[0033] When using the parallel dust explosion-proof electrical cabinet, by opening and closing the cabinet door 2, installing electrical equipment inside the explosion-proof cabinet 6, starting the fan 19, the fan 19 discharges the air inside the air inlet 3 into the interior of the explosion-proof cabinet 6 through the through hole, so that the interior of the explosion-proof cabinet 6 forms a positive pressure, and discharges the heat inside it into the interior of the outer cabinet 1 through the vent 9, and finally discharges the electrical cabinet through the air outlet 12. The first filter 14 and the second filter 15 can filter the air entering the interior of the electrical cabinet and intercept dust and other particles. On the outside of the electrical cabinet, dust is prevented from entering the interior of the electrical cabinet, ensuring ventilation and heat dissipation of the electrical cabinet; when it is necessary to clean the dust on the surface of the first filter 14 and the second filter 15, the first servo motor 10 is started, and the first servo motor 10 drives the second fixed plate 21 to move downward through the screw 11, and the second fixed plate 21 drives the lifting frame 22 to slide downward inside the outer cabinet 1, and at the same time drives the first filter 14 and the second scraper 26 to move downward, so that the first filter 14 and the first scraper 24 move relative to each other. The first scraper 24 is convenient for cleaning the dust and the like on the outer wall of the first filter 14. Since the fan 19 is working, the air outlet 12 continues to discharge heat to the outside, which can blow away the dust and the like cleaned on the first filter 14. The second scraper 26 can clean the dust and the like on the surface of the second filter 15. After the first filter 14 is cleaned, the second servo motor 23 and the rotating rod drive the adjustment frame 18 to rotate, and the adjustment frame 18 drives the fan 19 to rotate, and the air outlet direction of the fan 19 is downward. Under the action of the fan 19, The heat and air inside the explosion-proof cabinet 6 can be extracted and discharged through the through holes and the air inlet 3, so that the dust and the like cleaned on the second filter 15 can be blown away. The outside air enters the outer cabinet 1 and the interior of the explosion-proof cabinet 6 through the air outlet 12, which is convenient for dissipating heat to the electrical equipment inside the explosion-proof cabinet 6. It will not affect the ventilation and heat dissipation of the electrical cabinet, and prevents the cleaned dust and the like from continuing to adhere to the surfaces of the first filter 14 and the second filter 15, thereby ensuring the ventilation and heat dissipation of the electrical cabinet. The explosion-proof cabinet 6 is made of aluminum alloy.
