Detailed Description

The utility model will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

Before the anode carbon block is molded and prepared, firstly, the calcined petroleum coke is crushed and refined to be petroleum coke particles with different sizes. Firstly, as for the crushing and refining mode of the petroleum coke particles, most of the traditional crushing modes of the petroleum coke particles adopt a crusher to directly crush the petroleum coke particles, and after the petroleum coke particles with different sizes are filtered by a screen, the petroleum coke particles with different sizes are mixed in proportion. Because traditional broken mode adopts the breaker, this interval that just makes between the breaker need the staff to adjust to suitable broken size, but because petroleum coke is calcining, its hardness increases, this just makes when smashing petroleum coke calcining, because the broken dynamics of breaker is too big, and the phenomenon that leads to the petroleum coke grain to appear random bursting apart, causes to produce more powdered material of petroleum coke. For the subsequent mixing of petroleum coke, petroleum coke particles with different sizes need to be mixed in proportion, otherwise, the problem of the formed anode carbon block in the subsequent forming and roasting is easily caused, and the production cost is considered, the petroleum coke particles cannot be ensured to be completely used, more waste materials are produced, and the manufacturing cost of the anode carbon block is increased.

The utility model relates to a petroleum coke crushing and refining device before molding an anode carbon block, which comprises a crushing shell 1 and a refining piece 2, wherein the refining piece 2 is arranged in the shell, and the refining piece 2 is connected with a driving piece 3 for polishing and conveying petroleum coke particles on a polishing plate; because the calcined petroleum coke particles need to be refined, the refining piece 2 arranged in the device is driven by the driving piece 3 to refine the petroleum coke particles.

The refining part 2 is a refining grinding plate 4, and the refining grinding plate 4 is arranged in the crushing shell 1 in a sliding mode and is connected with the driving part 3; an inclined bottom plate 5 is arranged below the refining grinding plate 4 in a matched mode, the driving piece 3 drives the refining grinding plate 4 to be parallel to the inclined bottom plate 5, and petroleum coke particles on the inclined bottom plate 5 are refined; when fining the petroleum coke particles, the petroleum coke particles enter the crushing shell 1 and fall into the inclined bottom plate 5, at the moment, because of the action of gravity, the petroleum coke particles have the movement trend of sliding downwards along the inclined bottom plate 5, because of the arrangement of the refining grinding plate 4, the petroleum coke particles with the diameter larger than the gap between the refining grinding plate 4 and the inclined bottom plate 5 can not slide downwards along the inclined bottom plate 5, but for the petroleum coke particles with the diameter smaller than the gap between the refining grinding plate 4 and the inclined bottom plate 5, the petroleum coke particles can slide downwards along the inclined bottom plate 5 to fall out of the crushing shell 1, and the next step of sieving operation is performed. The aforesaid will refine and grind board 4 and inclined floor 5 parallel arrangement for refine and grind board 4 when moving under the drive of driving piece 3, it is greater than the petroleum coke particle that refines the clearance between mill board 4 and the inclined floor 5 to drive the diameter and enters into and refines between mill board 4 and the inclined floor 5, refine the breakage to petroleum coke particle, and after entering into and refine between mill board 4 and the inclined floor 5, under the drive of refining mill board 4, make petroleum coke particle ground and refine, and the landing from inclined floor 5. Because the strength of the calcined petroleum coke particles is high, the end faces of the branches of the petroleum coke particles can be polished seriously after the petroleum coke particles are polished and refined by the refining grinding plate 4, and further, the situation that more refined petroleum coke particles are generated during the subsequent dry mixing and stirring of the petroleum coke is avoided, so that the size ratio of the petroleum coke particles forming the chemotherapy is changed greatly, and the influence on the normal forming of the subsequent anode carbon block is caused.
