Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, and particularly relates to a double-roller type petroleum coke screening crusher for a descaling system. Background Art

[0002] The delayed coking process is one of the important process technologies for the lightening of heavy oil in the oil refining process. Since some lump cokes with a particle size of about 700 mm are generated during the hydraulic descaling process, and the particle size of individual lump cokes can even reach more than 1 m, it is rather difficult to transport and convey these lump cokes in the subsequent processes. Such larger-sized petroleum coke lumps need to be subjected to crushing and screening before being transported to the coke storage and loading systems via conveyor equipment. In addition, with the introduction of new environmental protection standards, the airtight crushing and screening operation of petroleum coke has become an irresistible trend.

[0003] The existing petroleum coke crushers can only crush petroleum coke, but during the crushing process, powdered and granular petroleum coke particles will be generated. The existing petroleum coke crushers cannot screen the powdered and granular petroleum coke particles, resulting in low screening efficiency. For example, the Chinese patent discloses "a double-roller type petroleum coke screening crusher for a descaling system", and its application number is: "CN202322007455.3", which includes: crushing rollers arranged in pairs and rotating towards each other. The crushing rollers include a main shaft and a plurality of roller tooth mechanisms sequentially installed on the shaft body of the main shaft along the length direction of the main shaft. The roller tooth mechanisms are arranged in a ring shape, and the roller tooth mechanisms include a plurality of roller teeth evenly spaced along the circumferential direction. Its device can only crush petroleum coke, but during the crushing process, powdered and granular petroleum coke particles will be generated and cannot screen the powdered and granular petroleum coke particles, resulting in low screening efficiency and relatively limited applicability.
