Description

Technical Field

[0001] The utility model relates to the technical field of rectifiers, in particular to a rectifier with a dust-proof filtering structure. Background Technique

[0002] During the operation of the rectifier, a large amount of dust and other impurities will accumulate on the dust-proof filter screen. Therefore, the quick replacement of the dust-proof filter screen is very important. It avoids the harm of dust accumulation to the rectifier and effectively improves the working efficiency of the rectifier. The publication number CN216451665U discloses a new type of rectifier with easy heat dissipation, including a rectifier body. A notch is formed through the side surface of the rectifier body, and a first dust-proof net is fixedly connected to the inner wall of the notch. An air inlet is formed through the top surface and the inner top surface of the rectifier body. A fixing plate is fixedly connected to the top surface of the rectifier body through bolts. A connecting pipe is fixedly connected to the opposite surface of the fixing plate, and a second dust-proof net is fixedly connected to the inner wall of the connecting pipe. The cold air is cooled again through the condensing pipe to dissipate heat from the components inside the rectifier body. The heat-absorbing cold air is discharged through the first dust-proof net; the goal of facilitating the quick heat dissipation of large rectifiers is achieved, avoiding the situation of low heat dissipation effect caused by most traditional large rectifiers using fan machines for heat dissipation, and avoiding the damage of the rectifier caused by excessive heat generated by the existing large rectifiers during long-term use. However, the dust-proof filter screen cannot be quickly replaced, and the whole rectifier needs to be disassembled for replacement, making the whole replacement process cumbersome and complex, reducing the dust-proof filtering effect of the rectifier, and being not conducive to improving the working efficiency of the rectifier, so improvement is needed.

One end of the connecting rod 17 is slidably connected to the telescopic frame 18 for installing a lead screw 19 and a sliding block 22. The lead screw 19 is threadedly connected to the outer surface of the telescopic frame 18 to fix the telescopic frame 18.

[0028] Working principle: First, rotate the turntable 13 clockwise by 90 degrees. At this time, the limit pin 12 slides along the guide rail groove 9, and at the same time, the rotating shaft 11 rotates synchronously with the turntable 13. Under the elastic force of the spring 10, the turntable 13 is ejected outward. At this time, the door frame 5 is released from the restriction of the turntable 13. At the same time, under the elastic force of the second spring 15, the buffer block 16 is ejected and drives the door frame 5 to be ejected. At this time, slide the filter screen 7 upward along the door frame 5 to take it out, slide the new filter screen 7 downward along the door frame 5 to put it in, and make it fit with the stop block 6. At this time, the filter screen 7 is fixed on the door frame 5. Rotate the door frame 5 into the square groove 4, and the door frame 5 presses the buffer block 16 inward until the buffer block 16 is located in the second groove 14. At this time, press the turntable 13 inward until the turntable 13 fits with the outer surface of the frame 1. At the same time, rotate the turntable 13 counterclockwise by 90 degrees, and the turntable 13 limits and fixes the door frame 5, completing the rapid replacement operation of the filter screen 7. Adjust the position of the mounting plate 25 according to the usage situation and the usage environment. First, the telescopic frame 18 slides along the connecting rod 17. After adjusting the position of the telescopic frame 18, rotate the handle 20 to make the lead screw 19 press the connecting rod 17, so as to fix the telescopic frame 18.
