Technical Field

The utility model relates to the technical field of electrostatic precipitator dust cleaning, in particular to an online dust cleaning device in an electrostatic precipitator.

Background technique

Electrostatic precipitator is a common dust removal equipment. The positive electrode of the electrostatic precipitator is made of metal plates of different geometric shapes, called dust collecting electrode. The performance of the electrostatic precipitator is affected by three factors: the nature of the dust, the equipment structure and the flue gas flow rate. During the use of the electrostatic precipitator, after the dust is adsorbed and filtered by the dust collecting plate, the dust inside the electrostatic precipitator needs to be cleaned regularly.

At present, the electrostatic precipitator on the market is cleaned by manually scraping the dust adhered to the inner wall. When the existing electrostatic precipitator is cleaned manually, not only the cleaning steps are cumbersome, but also the cleaning speed is slow. Therefore, we propose an online cleaning device for dust accumulation in the electrostatic precipitator.

Please refer to Figures 1, 2 and 3. The utility model provides a technical solution: an online dust cleaning device for an electrostatic precipitator, comprising an electrostatic precipitator body 1, a vibration frame 3 and an ash hopper 6. A bracket 2 is arranged above the inner wall of the electrostatic precipitator body 1, and a vibration frame 3 is arranged above the bracket 2. A motor 4 is installed above the vibration frame 3, and an eccentric wheel 5 is connected to the output end of the motor 4.

The movable groove 71 is opened below the inner wall of the ash hopper 6, and a cleaning scraper 72 is arranged on the inner side of the ash hopper 6.

A connecting seat 73 is passed through the lower part of the two cleaning scrapers 72, and the two ends of the connecting seat 73 are connected to the movable groove 71, and a mounting plate 74 is provided on the lower surface of the ash hopper 6; a through hole 75 is provided inside the mounting plate 74, and a connecting shaft 76 is connected to the upper part of the mounting plate 74 through a bearing seat; the top of the connecting shaft 76 is connected to the lower surface of the connecting seat 73, a motor 77 is installed below the mounting plate 74, and the output end of the motor 77 passes through the mounting plate 74 and is connected to the connecting shaft 76; a limiting ring 78 is provided above the inner wall of the ash hopper 6, and a guide groove 79 is provided inside the limiting ring 78; a guide block 710 is inserted into the guide groove 79, and the outer end of the guide block 710 is connected to the top of the cleaning scraper 72, the connecting seat 73 and the movable groove 71 are slidably connected, the cross-sectional size of the guide block 710 matches the cross-sectional size of the guide groove 79, and the cleaning scraper 72 fits the inner wall of the ash hopper 6.

During specific implementation, the starting motor 77 drives the connecting shaft 76 connected to the output end to rotate synchronously, and the rotating connecting shaft 76 drives the connecting seat 73 at the top and the cleaning scrapers 72 connected on both sides to rotate synchronously. Since the cleaning scrapers 72 are in contact with the inner wall of the ash hopper 6, the dust adhered to the inner wall of the ash hopper 6 can be scraped off as the cleaning scrapers 72 rotate. The scraped dust leaks out through the through holes 75 on the mounting plate 74, and the cleaning scraper moves stably along the guide groove 79 inside the limiting ring 78 through the guide block 710 connected to the top during rotation.

Please refer to Figures 1 and 4. A buffer assembly 8 is commonly provided between the bracket 2 and the vibration frame 3, and the buffer assembly 8 includes a fixed seat 81, a connecting sleeve 82, a docking plate 83, a guide rod 84 and a spring 85; the fixed seat 81 is provided at the upper end of the bracket 2, and a connecting sleeve 82 is sleeved on the upper part of the fixed seat 81, and the top of the connecting sleeve 82 is connected to the vibration frame 3; a docking plate 83 is passed through the interior of the fixed seat 81, and both ends of the docking plate 83 are connected to the inner wall of the connecting sleeve 82, and a guide rod 84 is passed through the interior of the docking plate 83; both ends of the guide rod 84 are connected to both sides of the inner wall of the fixed seat 81, and a spring 85 is sleeved on the outer side of the guide rod 84, and both ends of the spring 85 are respectively connected to the fixed seat 81 and the docking plate 83, and the docking plate 83 forms a telescopic structure with the fixed seat 81 through the spring 85, and the guide rods 84 are symmetrically distributed about the center line of the docking plate 83.

As the eccentric wheel 5 rotates, when the larger end of the eccentric wheel 5 rotates downward, it will squeeze the vibration frame 3 downward. The downward moving vibration frame 3 drives the connecting sleeve 82 to move downward. During the downward movement of the connecting sleeve 82, the connected docking plate 83 moves downward synchronously along the guide rod 84, and the spring 85 sleeved on the outer side of the guide rod 84 is squeezed by the downward moving docking plate 83. When the larger end of the eccentric wheel 5 rotates upward, the eccentric wheel 5 is separated from the vibration frame 3, and the vibration frame 3 on the outside can be automatically reset upward by the elastic force of the spring 85 without being affected by the outer side. The motor 4 drives the eccentric wheel 5 to rotate, so that the vibration frame 3 moves up and down to drop the dust adhered to the dust collecting plate in the electrostatic precipitator body 1 to the inside of the ash collecting hopper 6. The buffer assembly 8 provided between the bracket 2 and the vibration frame 3 can start the buffering effect on the moving vibration frame 3, so that the buffering effect of the dust online cleaning device in the electrostatic precipitator is better.

To sum up, when using the online cleaning device for dust accumulation in the electrostatic precipitator, the electrostatic precipitator body 1 is transported to the designated use area, and the electrostatic precipitator body 1 adsorbs and filters the dust through the dust collecting plate arranged inside.

When the larger end of the eccentric wheel 5 rotates upward, the eccentric wheel 5 is separated from the vibration frame 3. As the vibration frame 3 drives the dust collecting plate to move up and down, the adsorbed and filtered dust can be shaken. Finally, the dust adhered to the inner wall of the ash hopper 6 is scraped and cleaned through the cleaning component 7.
