Embodiment 1

[0024] see Figure 1-3 , this embodiment provides a petroleum coke calcining device for prebaked anodes, including a calcining cylinder 1 and a central column 7 arranged inside the calcining cylinder 1, and an annular shape is formed between the calcining cylinder 1 and the central column 7 A calcining channel, the upper part of the calcining cylinder 1 is provided with a number of material inlets, the bottom of the calcining cylinder 1 is provided with a number of discharge ports 2, the inner wall of the calcining cylinder 1 and the outer wall of the central column 7 are provided with heating plates; the annular calcining channel There are four sets of stirring assemblies inside. Specifically, the stirring assemblies include transmission rods 5 vertically distributed inside the annular calcination channel and two groups of paddle plates 3 that are rotatably arranged on the transmission rods 5. The transmission assembly includes two sets of guide rings arranged above the centr...

Embodiment 2

[0034] see figure 1 and image 3 , a petroleum coke calcining device for prebaked anodes. Compared with Embodiment 1, the side of the shifting plate 3 far away from the transmission rod 5 in this embodiment is provided with a plurality of guide grooves 4, through which the guide grooves 4 The setting of the set makes the petroleum coke raw material move to the direction of the inner wall of the calcining cylinder 1 and the outer wall of the center column 7 by the shifting plate 3, and the petroleum coke raw material can flow to the other side of the shifting plate 3 through the material guide groove 4, thereby avoiding two groups of When the transmission rods 5 are close to each other, the corresponding shifting plate 3 will cause a greater extrusion effect on the petroleum coke raw material, thereby affecting the smooth movement of the two groups of transmission rods 5 .

Abstract

The invention provides a petroleum coke calcining device for a prebaked anode, and belongs to the technical field of petroleum coke calcining. The device comprises a calcining cylinder and a central column arranged inside the calcining cylinder, an annular calcining channel is formed between the calcining cylinder and the central column, a plurality of feed inlets are formed in the upper portion of the calcining cylinder, a plurality of discharge outlets are formed in the bottom of the calcining cylinder, and heating plates are arranged on the inner wall of the calcining cylinder and the outerwall of the central column correspondingly; and four groups of stirring assemblies are arranged inside the annular calcining channel. According to the device, the four groups of stirring assemblies are arranged in the annular calcining channel, two opposite groups of stirring assemblies are driven to be close to each other by a first driving assembly, and material poking plates corresponding to the two groups of stirring assemblies form a V-shaped structure with a certain included angle under the action of petroleum coke raw materials, so that the petroleum coke raw materials are poked to theinner wall of the calcining cylinder and the outer wall of the central column, the petroleum coke raw materials can be in better contact with the heating plates, and the device has the advantage of good calcination effect.

Description

technical field [0001] The invention belongs to the technical field of petroleum coke calcining, in particular to a petroleum coke calcining device for prebaked anodes. Background technique [0002] Petroleum coke is one of the main by-products of the oil refining industry, and it is the main raw material for the preparation of carbon materials, especially prebaked anodes for aluminum. Petroleum coke is a black solid coke produced by cracking and coking the vacuum residue of petroleum through a calcination device at 500-550°C. Its appearance is a black or dark gray honeycomb structure, and the pores in the coke block are mostly oval and interconnected. [0003] In the prior art, the calcination of petroleum coke is mostly carried out in a rotary kiln, but when the existing rotary kiln calcines petroleum coke, the petroleum coke cannot be fully contacted with the heating mechanism, resulting in a poor calcination effect of petroleum coke. Difference. Contents of the inven...
