Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pyrolytic crude carbon black treatment technology, and in particular relates to a vibration impurity removal device for pyrolytic crude carbon black. Background Technology
[0002] Waste tire pyrolysis is an irreversible thermochemical reaction that uses high temperatures in an oxygen-free or oxygen-deficient atmosphere to decompose the organic matter in waste tires, releasing volatile products and forming solid coke. During incomplete thermal degradation, gaseous, liquid, and solid products can be formed. This method can completely decompose waste tires into useful products such as pyrolysis oil, pyrolysis carbon black, and pyrolysis non-condensable gases. Carbon black, a black powder obtained from the pyrolysis or incomplete combustion of hydrocarbon compounds, possesses excellent tinting strength, hiding power, and weather resistance. In the rubber, plastics, and coating industries, carbon black is often used as a reinforcing agent and filler to improve the physical properties and durability of products.
[0003] However, pyrolytic coarse carbon black has strong interparticle aggregation and high oil absorption, which leads to poor dispersion in the matrix, affecting its reinforcing effect and coloring power. Therefore, pyrolytic coarse carbon black needs to be finely ground and further processed before it can be used further. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.
[0025] This utility model embodiment provides a specific implementation method for a vibration-based impurity removal device for pyrolysis crude carbon black. Figure 1 This is a schematic diagram of the structure of the pyrolysis crude carbon black vibration impurity removal equipment according to an embodiment of the present invention. Figure 2 , Figure 3 This is a partial structural schematic diagram of a vibration impurity removal device for pyrolysis crude carbon black according to an embodiment of the present invention. (Reference) Figure 1 , Figure 2As shown, the device includes at least: a magnetic separator 1; a grinding mill 2, including: a cylinder with a feed inlet and a discharge outlet, connected to the discharge outlet of the magnetic separator 1 via the feed inlet; a liner fixed inside the cylinder; grinding disc hammers that, driven by a grinding drive device, move closer to or further away from the liner to grind the pyrolytic coarse carbon black between the liner and the grinding disc hammers; a classifier 3 connected to the discharge outlet of the grinding mill 2; and a first cyclone dust collector 4, with its feed inlet connected to the discharge outlet of the classifier 3. Furthermore, the grinding disc hammers are connected to the drive shaft of the grinding drive device.
[0026] The iron separator 1 removes any metal impurities not completely removed in the previous process. The coarse carbon black after impurity removal is easier to grind, and the grinding process is free from impurity interference, resulting in higher quality carbon black. The removed impurities are automatically stored in a collection trolley below the iron separator 1. The discharge port of the iron separator 1 is connected to the feed port of the grinder 2 for feeding. The coarse carbon black after impurity removal enters the grinder 2 for grinding. A main drive unit is located on the upper part of the base of the grinder 2. This main drive unit drives the grinding disc hammers, which cooperate with the liner plates fixed on the cylinder to grind the sucked-in coarse carbon black to the required particle size. An air distribution port is located on the lower right side of the grinder 2 cylinder. A classifier 3 is located on the upper part of the grinder 2. The classifier 3 contains an impeller, and the drive unit on the upper part of the classifier 3 sends the powder that meets the particle size requirements into the first cyclone dust collector 4.

[0027] Furthermore, the grinding machine 2 also includes a support plate 5 and a vibration spring 6 disposed on the support plate 5; the cylinder is connected to the support plate 5 via the vibration spring 6. The vibration spring 6 can effectively reduce the impact of the cylinder on the support plate 5 during the operation of the grinding machine 2. In some embodiments, four sets of vibration springs 6 are disposed on the support plate 5, symmetrically arranged front and back. This arrangement can more effectively disperse the impact force of the cylinder on the support plate 5, and the force is more balanced, reducing equipment wear.
[0028] In some embodiments, the classifier 3 is connected to the first cyclone dust collector 4 via a negative pressure conveying pipe 7. The classifier 3 feeds the carbon black powder that meets the particle size requirements into the feed inlet of the first cyclone dust collector 4 through the negative pressure conveying pipe 7.
[0029] To improve conveying efficiency, the pyrolysis coarse carbon black vibrating impurity removal equipment also includes a conveying screw conveyor 8 connected to the feed inlet of the iron separator 1. The conveying screw conveyor 8 is inclined, and its discharge port is higher than its feed inlet. Furthermore, the conveying screw conveyor 8 is installed such that its discharge port is higher than its feed inlet, and the angle between the conveying screw conveyor 8 and the horizontal plane is 35 degrees. This arrangement of the conveying screw conveyor 8 allows the carbon black to automatically aggregate under gravity during transport, improving conveying efficiency. The drive unit of the conveying screw conveyor 8 is located at the left end, the feed inlet is vertically located on the upper left side of the screw cylinder, and the discharge port is located on the lower right side of the screw cylinder.

The raw material buffer silo 9 is set up separately from the support frame. In the middle of the raw material buffer silo 9, there are four sets of automatic weighing modules that can automatically measure the weight of the materials entering the silo.
[0031] In some embodiments, a material extractor screw conveyor 11 is installed at the bottom of the raw material buffer silo 9, and the raw material buffer silo 9 is connected to the conveying screw conveyor 8 via the material extractor screw conveyor 11.

[0032] In some embodiments, the inlet of the second cyclone dust collector 10 is connected to the outlet of the pyrolysis reactor, and the outlet of the second cyclone dust collector 10 is connected to the suction fan 13 via a negative pressure duct 12. The coarse carbon black discharged from the pyrolysis reactor after the waste tires are pyrolyzed is drawn into the second cyclone dust collector 10 through a negative pressure conveying pipe. An inlet is located on the upper left side of the second cyclone dust collector 10, connected to the conveying pipe. A negative pressure air outlet is vertically located at the top of the feeding cyclone dust collector, connected to the suction fan 13 via a negative pressure duct 12.

[0035] The working process of the above-mentioned pyrolysis crude carbon black vibration impurity removal equipment is as follows:
[0036] The coarse carbon black discharged from the pyrolysis reactor after the waste tires are pyrolyzed is removed by the iron remover 1 to remove metal and non-metal impurities that were not completely removed in the previous process. The treated coarse carbon black then enters the grinding mill 2 for grinding. The coarse carbon black enters the cylinder of the grinding mill 2 through the feed port. The cylinder is equipped with a liner plate. The grinding disc hammer head moves closer to or away from the liner plate under the drive of the grinding drive device and grinds the pyrolyzed coarse carbon black between the liner plate and the grinding disc hammer head. The ground carbon black enters the classifier 3 through the discharge port of the grinding mill 2. The classifier 3 sends the carbon black that meets the particle size requirements to the first cyclone dust collector 4. After the first cyclone dust collector 4 removes dust from the carbon black, the carbon black that meets the requirements is obtained.
