Technical Field
[0001] This utility model belongs to the field of producer furnace technology, specifically a producer furnace ash basin scraper. Background Technology
[0002] A gasifier is a reactor used to produce coal gas, water gas, and semi-water gas. The furnace body is cylindrical, with an outer shell made of steel plate or brick, lined with refractory bricks, and equipped with feeding equipment, blast pipes, and gas pipes. The ash basin is an important component of the gasifier, mainly used to collect and store the ash produced inside the furnace. Its functions include: 1. Collecting ash: Located at the bottom of the gasifier, the ash basin collects the ash produced during coal combustion and gasification, preventing it from falling into other parts of the furnace and affecting the normal operation of the equipment; 2. Protecting the grate: The ash basin protects the grate from the direct impact of high-temperature ash, extending the grate's service life; 3. Preheating the gasifying agent: The ash layer preheats the gasifying agent through heat exchange with air and water vapor, improving gasification efficiency.
[0003] The ash inside the gasifier is automatically discharged through the rotation of the ash basin and the action of the large ash cutter. The rotation of the ash basin helps the ash to be discharged smoothly, ensuring smooth operation inside the furnace. The rotation of the ash basin is usually achieved through a built-in gear plate drive, a built-in worm gear drive, a worm gear drive, or a hydraulic ratchet drive.
[0004] When the ash basin is in operation, some ash residue will adhere to the inner wall of the ash basin. If it is not cleaned in time, it will affect the normal operation of the ash basin. Currently, it is cleaned manually, which is quite labor-intensive for the staff. Utility Model Content
[0005] To address the problems mentioned above, this utility model provides a generator ash basin scraper. A support frame is installed outside the ash basin, and an extension arm on the support frame extends into the ash basin. A scraper on the extension arm abuts against the inner wall of the ash basin. When the ash basin rotates, the scraper can scrape off the ash and slag on the inner wall of the ash basin, thereby ensuring the normal operation of the ash basin. Furthermore, it eliminates the need for manual cleaning by workers, reducing their workload.
[0006] This utility model provides a scraper for a producer ash basin, including a support frame, an extension arm on the support frame, the extension arm being bent and extending into the ash basin, and a scraper being provided at the end of the extension arm away from the support frame, the scraper abutting against the inner wall of the ash basin.
[0007] By adopting the above technical solution, a support frame is set on the outside of the ash basin, and the extension arm on the support frame extends into the ash basin. The scraper on the extension arm abuts against the inner wall of the ash basin. When the ash basin rotates, the scraper can scrape off the ash residue on the inner wall of the ash basin, thereby ensuring the normal operation of the ash basin. Moreover, it eliminates the need for manual cleaning by staff, reducing the labor intensity of the staff.
