Tumbler periodic self-driven petroleum coke screening device

Abstract

The invention discloses a tumbler periodic self-driven petroleum coke screening device which comprises a screening bin, supporting legs, a feeding opening and a bin cover. The screening bin comprises a material preparation layer, a crushing layer, a screening layer, a ventilation layer, a quantitative feeding device, a self-service type gravitational potential energy crushing mechanism, a self-service type equipotential dust removal swing screening mechanism and an intermediate belt type driving secondary screening preheating device. The invention belongs to the technical field of petroleum coke calcination screening devices, and particularly relates to a tumbler periodical self-driven petroleum coke screening device. The self-service principle, the equipotential principle, the tumbler principle and the Venturi principle are combined and applied to the technical field of petroleum coke calcination screening devices, and the problems that in the petroleum coke screening process, petroleum coke needs to fall through a screen to be screened, and the screening efficiency is low are thoroughly solved. And meanwhile, the contradictory technical problem that the residence time of the petroleum coke on the screen needs to be prolonged in order to improve the screening effect is solved, and the problem that the screening effect of the petroleum coke is not ideal in the screening process is solved.

Description

technical field [0001] The invention belongs to the technical field of petroleum coke calcining and screening devices, in particular to a periodical self-driven petroleum coke screening device of a tumbler. Background technique [0002] Petroleum coke is a product obtained by distilling crude oil to separate light and heavy oil, and then thermally cracking the heavy oil. Petroleum coke is calcined in a vacuum to produce calcined coke. When the petroleum coke is calcined, the petroleum coke is first introduced into the crusher with a forklift for crushing, and the crushed petroleum coke is transported to the calciner through the conveyor belt and hoist for calcination. [0003] The current petroleum coke raw materials are uniformly sent to the crusher by a forklift for crushing treatment or manually beaten and crushed. This crushing method not only increases the crushing burden, but also needs to be transferred to the screening equipment for screening processing after crushin...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a tumbler periodic self-driven petroleum coke screening device, according to the need to make the petroleum coke fall through the screen for screening in the process of material screening, and at the same time It is necessary to increase the contradictory characteristics of the retention time of petroleum coke on the screen in order to improve the screening effect. The principle of self-service (using gas dust removal while providing shaking power to the pear-shaped swinging magnetic screening cylinder), the principle of equipotential (through multi-directional etc. Potential dedusting pipe and self-service equipotential exhaust pipe to remove dust in multiple directions during the crushing and screening process of petroleum coke, and at the same time drive the pear-shaped swinging magnetic screening cylinder in multiple directions), tumbler principle and Venturi principle Combined with the application in the technical field of petroleum coke calcining and screening equipment, it completely solves the problem that in the petroleum coke screening process, it is necessary to make the petroleum coke fall through the screen for screening, and at the same time, it is necessary to increase the residence time of the petroleum coke on the screen to improve the screening effect. Contradictory technical problems, overcome the problem of unsatisfactory screening effect of petroleum coke in the screening process
