Description

Technical Field

[0001] The invention relates to the technical field of catalytic cracking oil slurry, in particular to a filtering and separating device for catalytic cracking oil slurry. Background Art

[0002] In the field of petrochemicals, catalytic cracking is an important refining process. A large amount of slurry oil is produced during the catalytic cracking process. The slurry oil contains impurities such as catalyst particles, colloids, asphaltene, etc. These impurities will have an adverse effect on the subsequent processing and product quality. Therefore, the development of a filtering and separation equipment for catalytic cracking slurry oil has important practical significance.

[0003] In the prior art, due to the physical properties of catalytic cracking oil slurry such as high density and high viscosity, the filtering effect of traditional filtering and separation equipment is relatively low. When the traditional oil slurry enters the filtering equipment, the impact force generated by the oil slurry during flow is directly sprayed or poured onto the surface of the filtering device, making it difficult to filter evenly. Secondly, due to the high density and high viscosity of the catalytic cracking oil slurry, the solid particles in the oil slurry quickly settle and aggregate after entering the filter box, making it difficult for the filter box to fully exert its good filtering effect. Traditional stirring mechanisms are mostly unidirectional, which makes it possible for the oil slurry with high density and high viscosity to flow in the direction of unidirectional stirring when being stirred, thereby reducing the filtering effect. Secondly, due to the limited filtering effect of the filter net, tiny particles with a density lower than the filter net may still pass through the filter net, and traditional filtering equipment has no effective means to deal with tiny solid particles after passing through the filter net. The tiny solid particles may quickly settle when there is no effective stirring means, thereby reducing the overall filtering effect of the overall filtering equipment. Summary of the invention

[0038] Working principle: When in use, through the first rotating tube 504, when the oil slurry enters the oil inlet pipe 501, the impact force of the oil slurry flow drives the output tube 505 to rotate. As the output tube 505 rotates, the impact force automatically driven by the oil slurry flow is released, and then it flows evenly into the filter box 608 through the flow hole 507. Then, the motor is started by the PLC controller, and the motor output shaft rotates to drive the third bevel gear 606 to rotate. The rotation of the third bevel gear 606 drives the first rotating column 603 and the second bevel gear 604 to rotate in different directions. The rotation of the first bevel gear 602 drives the filter box 608 to rotate. The rotation of the first rotating column 603 drives the multiple first stirring plates 607 to rotate, so that the oil slurry inside the filter box 608 is stirred in different directions to prevent the oil slurry from settling when it enters the filter box 608 and affecting the filtering effect. The oil slurry filtered by the filter box 608 settles on the right side of the dividing plate 709. The rotation of the first rotating column 603 drives the first synchronous wheel 904 to rotate. The first synchronous wheel 904 rotates The linkage bevel gear 903 is driven to rotate by the first belt 905, and the linkage bevel gear 903 rotates through the first threaded column 702 to drive the first push plate 710 to move, so that the precipitated tiny particles are fixed and pushed into the surface of the second push plate 805. When the first rotating column 603 rotates, the second synchronous wheel 906 is also driven to rotate. The second synchronous wheel 906 rotates through the second belt 908 to drive the third synchronous wheel 907 to rotate. The rotation of the third synchronous wheel 907 causes the second threaded column 802 to rise, thereby driving the second push plate 805 to push the large particles of solid on the surface of the second push plate 805 to the inside of the collecting box 811, so as to facilitate the cleaning of the precipitated tiny particles.
