Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pyrolysis carbon black treatment equipment, and particularly relates to a modification treatment and feeding device for pyrolysis carbon black of a mixer. Background Art
[0002] In recent years, due to the increasing number of automobiles, the quantity of waste tires has been increasing year by year, which poses a serious threat to the ecological environment. Nowadays, the most common way to treat waste tires is pyrolysis treatment, and pyrolysis carbon black is one of the most important products of pyrolysis.
[0003] Due to the unique physical and chemical properties of pyrolysis carbon black, it has broad application potential in fields such as rubber, coatings, and plastics. Compared with virgin carbon black, the performance of pyrolysis carbon black produced by the thermal pyrolysis of waste tires may vary. This is mainly because of the differences in conditions such as temperature, time, and atmosphere during the pyrolysis process, as well as the material differences of the waste tires themselves, resulting in large fluctuations in the performance parameters of pyrolysis carbon black (such as specific surface area, structure degree, surface chemical properties, etc.); at the same time, pyrolysis carbon black may contain incompletely pyrolyzed rubber particles, metal impurities (such as steel wire residues), etc., and these impurities will affect the purity and use performance of carbon black; in addition, the dispersibility of pyrolysis carbon black is poor, and the dispersibility of unmodified pyrolysis carbon black in water-based or organic solvents may be poor, and it is easy to agglomerate, affecting its dispersion uniformity in composite materials and the performance of the final product.
[0004] To improve the performance of pyrolysis carbon black, currently, a plasma generator is mostly used to modify pyrolysis carbon black. However, the existing modification process needs to be carried out separately by workers. That is, when modifying, workers need to put pyrolysis carbon black into a sample bottle and manually put the sample bottle into the plasma generator. After the modification is completed, the sample bottle is taken out manually by workers for the next mixing process. The operation is complex and inconvenient to use. Content of the Utility Model

[0034] Workflow: Put the pyrolytic carbon black to be processed into the feed bin 1, start the screw conveyor 16, and the screw conveyor 16 conveys the pyrolytic carbon black in the feed bin 1 to the airflow pulverizing bin 3. The airflow pulverizing bin 3 pulverizes the pyrolytic carbon black. The pulverized pyrolytic carbon black enters the classifier 2, and the classifier 2 screens the particle size of the pyrolytic carbon black. After the particle size screening, the pyrolytic carbon black enters the cyclone separator 4, and then enters the lower bottle body 74 of the sample bottle 7 through the discharge port 5 of the cyclone separator 4. At this time, the solenoid valve is closed, and the pyrolytic carbon black is temporarily stored in the lower bottle body 74 for modification.
[0035] During modification, first start the vacuum machine 17. The vacuum machine 17 evacuates the inside of the plasma generator 6 to form a vacuum environment inside the plasma generator 6. Then open the valve of the required plasma atmosphere gas cylinder to allow the required gas to enter the plasma generator 6. The gas enters the sample bottle 7 through the air inlet 73 and contacts the pyrolytic carbon black. Start the drive motor 11. The drive motor 11 drives the lower bottle body 74 to rotate through the transmission of the gear 12 and the external gear ring 13, so that the stirring plate 15 rotates relative to the lower bottle body 74, stirring the pyrolytic carbon black to make the gas and the pyrolytic carbon black contact more fully and improve the modification effect.
[0036] After the modification is completed, open the solenoid valve, and the modified pyrolytic carbon black is introduced into the internal mixer 9, and the internal mixer 9 is started for the internal mixing process.
[0037] It should be understood that the airflow mill pulverizer is an existing device, and the pulverizing function of the airflow pulverizing bin 3 and the particle size screening function of the classifier 2 are prior arts and will not be elaborated here.
