Description

Technical Field

[0001] The utility model relates to the field of mesophase carbon microsphere preparation, in particular to a mesophase carbon microsphere preparation device. Background Art

[0002] Mesophase carbon microbeads are a common lithium battery negative electrode material, and using bituminous coal to produce mesophase carbon microbeads is one of the most common production methods. Its production generally includes heating, sedimentation, separation, recovery, secondary polymerization and other processes; due to the large variety of bituminous coals, their melting points also have certain differences, and the rate of changing from solid to molten state is also different. Although the existing processing equipment is also equipped with a stirring structure, when there are more solids in the bituminous coal raw materials, the stirring effect is not good, it is difficult to fully carry out the polymerization reaction, and the stirring resistance is also large, which affects the service life of the stirring structure. At the same time, in order to make the reaction sufficient, the overall heating and reaction time of the raw materials needs to greatly exceed the theoretical reaction time, resulting in low production efficiency and high energy consumption. At the same time, bituminous coal has certain toxicity. The transportation process between sedimentation and separation not only reduces production efficiency, but also is harmful to the health of workers, which does not meet the needs of modern production.

[0003] To solve the above problems, patent number CN201620565150.1 discloses a device for preparing mesophase carbon microspheres. A heating mesh plate is provided in the reaction chamber device to intercept solid asphalt coal and heat it to a molten state. A push plate is provided to spread the asphalt coal raw materials to improve the melting efficiency. The molten asphalt coal passes through the heating mesh plate and falls to the bottom of the reaction chamber to complete the high-temperature polymerization reaction, and then directly enters the sedimentation and separation device to complete sedimentation and separation. The production efficiency is high, and no manual handling is required, which avoids harm to the health of workers.

[0004] The mesophase carbon microsphere preparation device disclosed in the above patent uses a heated mesh plate to intercept solid bituminous coal and heat it to a molten state, and the molten bituminous coal is easy to clog the mesh holes of the heated mesh plate when passing through the mesh holes.

[0022] Among them, a feeding port is opened on the upper part of the outer wall of the heating tank body 1 and a feeding hopper 2 is installed on the feeding port, which is convenient for feeding; wherein, a discharge port at the bottom of the heating tank body 1 is installed with a discharge pipe 6 and a sedimentation separation device is connected through the discharge pipe 6, which is convenient for the next step of work; wherein, the slow drive component includes a reduction gear 3 locked and installed on the top of the rotating shaft 7, and the outer wall of the reduction gear 3 is meshed and connected with a transmission gear 4, and the diameter of the reduction gear 3 is larger than the diameter of the transmission gear 4, so that the rotating shaft 7 can rotate slowly; wherein, the power input end of the transmission gear 4 is connected to the power output end of the motor 5, which is convenient for driving; wherein, the fixed comb frame 10 includes a longitudinal rod 101 and a cross rod 102, the longitudinal rod 101 is fixedly installed on the inner wall of the heating tank body 1, and the longitudinal rod 101 is welded with a plurality of cross rods 102 in a straight and equidistant array from top to bottom, and the cross rod 102 is hollow inside and is installed with a heating wire 11, which is convenient for heating the solid materials rushed together.

[0023] The working principle of the utility model is as follows: the mesophase carbon microsphere preparation device disclosed in the utility model can drive the unmelted large-particle solid materials that cannot pass through the gaps between the stirring rods 9 to the fixed comb frame 10 for heating through a plurality of slowly rotating transversely installed stirring rods 9, in combination with a heatable fixed comb frame 10, so that the large-particle solid materials that are not melted in the liquid material can be quickly heated, and the filter assembly is not easily blocked.
