Rotary kiln for producing petroleum coke

Abstract

The invention provides a rotary kiln for producing petroleum coke. The rotary kiln comprises a barrel body. Multiple wheel belts are arranged outside the barrel body in a sleeving manner and fixedly connected. A limiting housing is arranged on the upper half of each wheel belt in a housing manner. Each limiting housing is internally provided with multiple rolling wheels which are sequentially arranged into a semicircle. The rolling wheels are in rolling connection with the upper halves of the wheel belts. Support pillars are fixedly connected to the outer wall of each limiting housing, whereinthe support pillars are symmetrically arranged at the two sides of the barrel body. A shock absorption spring is connected to the bottom of each support pillar. A base is connected to the bottom of each shock absorption spring. A mixing mechanism and a beating mechanism are alternately arranged inside the barrel body in the axial direction. The mixing mechanism is composed of multiple mixing components which are uniformly distributed in the circumferential direction. Each mixing component comprises a support plate and a mixing plate, wherein each support plate is fixedly connected with the inner wall of the barrel body, and each mixing plate is fixedly connected with the corresponding support plate. The beating mechanism comprises multiple chains and beating balls, wherein the chains areuniformly distributed in the circumferential direction, and the beating balls are fixedly connected with the chains. According to the rotary kiln, when the barrel body rotates, the shaking degree is low; the service life is long; calcination raw materials are not likely to adhere to the inner wall of the barrel body; the energy consumption is lowered; and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of rotary kilns, and in particular relates to a rotary kiln for petroleum coke production. 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. From the appearance, the coke is black lumps or particles with irregular shapes and sizes. It has a metallic luster, and the particles of coke have a porous structure. The main element is carbon, and the carbon content reaches 80%. The production process of petroleum coke requires the use of rotary kilns for calcination. Rotary kiln refers to rotary calcining kiln. In many production industries such as building materials, metallurgy, chemical industry, environmental protection, etc., rotary cylinder equipment is widely used for mechanical, physical or chemical treatment of solid materials. The size of the rotary kiln is large, and it will shake when it ...

AI Technical Summary

Problems solved by technology

The size of the rotary kiln is large, and it will shake when it is rotated. After a long time of use, the seal between the cylinder and the kiln head cover and kiln tail cover will become poor, and the service life of the rotary kiln will be shortened; Adhesion to the inner side of the cylinder, resulting in reduced output, and at the same time will reduce the thermal conductivity of the cylinder, increase energy consumption, and reduce the production efficiency of petroleum coke
