Description

Technical Field

[0001] The present application relates to the field of dust removal in power plants, and in particular to a dust removal device for power plants. Background Art

[0002] A power plant, also known as a power station, is a facility that converts various naturally occurring primary energy sources into electrical energy (secondary energy). In the late 19th century, with the growing demand for electricity, the idea of establishing power production centers began to emerge. Advances in motor manufacturing technology, the expansion of electrical energy applications, and the rapidly growing demand for electricity in production necessitated the emergence of power plants. Power plants utilize various methods: those that rely on thermal power, those that rely on hydropower, and others that rely on solar (photovoltaic) power, wind power, and tidal power. Nuclear power plants, powered by nuclear fuel, are playing an increasingly important role in many countries around the world.

[0003] The patent document with announcement number CN212188410U discloses a dust removal equipment for power plants. The utility model discloses a dust removal equipment for power plants, including an ash hopper, a discharge bin welded at the bottom of the ash hopper, a recovery box provided directly below the discharge bin, and a filter fixedly installed at the bottom of the discharge bin. In the above application document, the scraper seat is driven to move in an inclined state by the extension and contraction of the second electric push rod to clean the ash accumulated on the filter screen. However, when the scraper seat moves on the filter screen, if ash falls from above, it may fall to the left side of the scraper seat. The scraper seat can only push the ash to the right, and the ash on the left side of the scraper seat will accumulate on the filter screen, which is not convenient for completely cleaning the ash accumulated on the filter screen.

[0024] When the above-mentioned equipment is used in a boiler device of a power plant, the ash is first loaded into the ash hopper 1 during the waste slag recovery process, and the dust will fall into the lower hopper 2 and be filtered by the filter plate 3. At this time, large pieces of ash will accumulate on the filter plate 3. By starting the dual-axis motor 401 to rotate the first rotating shaft 402, the rotation of the first rotating shaft 402 will drive the turntable 403 to rotate, and the turntable 403 will drive the rotating column 404 to rotate around the center of the turntable 403. At this time, the rotating column 404 will continuously push Pull the push rod 405, and then drive the push plate 406 to slide left and right in the lower hopper 2. The push plate 406 will push the ash on the filter plate 3 to the right so that it falls into the storage bin 5 and is collected by the storage box 6. At this time, the ash falling from above will fall onto the push plate 406. As the push plate 406 is pulled to the left, the scraper 407 will scrape off the ash accumulated on the push plate 406, and then push it into the storage bin 5 through the rightward movement of the push plate 406, and so on and so forth, so as to collect the ash on the filter plate 3.
