Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a petroleum coke crushing device. Background Art

[0002] Petroleum coke is the final product of the petroleum refining process. It is mainly produced by cracking and coking the vacuum residue of petroleum at 500-550℃ in a coking unit to produce black solid coke. It is an amorphous carbon body, or a highly aromatized high molecular carbide containing tiny graphite crystals in the form of needles or granules.

[0003] Before use, petroleum coke needs to be crushed into small particles. The crushing process needs to be screened so that the uncrushed petroleum coke can be screened out and crushed again. However, petroleum coke has a certain viscosity and is easy to clog the screening plate during the screening process, resulting in subsequent screening failure. Based on these problems, Chinese patent CN219965502U discloses a petroleum coke crushing device. After the petroleum coke is crushed, it falls on the filter plate. The qualified petroleum coke falls from the filter plate, and the unqualified one is intercepted by the filter plate. In order to prevent the filter plate from being blocked, the rotating shaft drives the scraper to scrape the filter plate, so that the petroleum coke adhered to the filter plate is scraped clean to prevent the filter plate from being blocked. The high-pressure air can be discharged from the air outlet through the rotating shaft and the scraper to purge the filter plate, further clean the filter plate to prevent the filter plate from being blocked.

[0004] Petroleum coke itself contains a certain amount of moisture. When the device is used to crush petroleum coke, a large amount of petroleum coke powder containing moisture will adhere to the surfaces of the moving cutting knife, top cutting knife, scraper and filter plate in the device, which will not only reduce the sharpness of the crushing parts inside the device and increase the difficulty of cleaning, but also cause a large amount of waste of petroleum coke raw materials.
