Description

Technical Field

[0001] The utility model belongs to the technical field of waste tires, and in particular relates to a new type of equipment for ash reduction and desulfurization of waste tires by pyrolysis of carbon black. Background Art

[0002] In recent years, my country's automobile industry has developed rapidly, and the number of cars owned is huge. As a result, there are more and more waste tires, which are then discarded at will to form "black pollution". Because they are difficult to degrade in nature, they pose a huge threat to the environment, ecology and humans. Statistics show that there are currently more than 3 billion waste tires accumulated in the world, and it will still increase at a rate of about 1 billion per year. Among the products of waste tire pyrolysis, pyrolytic carbon black is the key product of waste tire pyrolysis. Ash reduction and desulfurization equipment is needed to treat pyrolytic carbon black.

[0003] During operation, the existing ash reduction and desulfurization equipment uses a driving structure to cooperate with a stirring mechanism to stir pyrolytic carbon black and sulfuric acid, and cooperates with a heating mechanism to acid wash the pyrolytic carbon black, thereby achieving the purpose of ash reduction and desulfurization. However, during the acid washing process, a large amount of harmful gases are easily generated. The gases are directly discharged into the air, which can easily reduce the air quality and cause pollution to the environment. Therefore, we provide a new type of equipment for ash reduction and desulfurization of pyrolytic carbon black from waste tires. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of equipment for ash reduction and desulfurization of waste tire pyrolysis carbon black, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of equipment for ash reduction and desulfurization of waste tire pyrolysis carbon black, comprising a desulfurization box, a heating box fixedly connected to the bottom of the desulfurization box, a graphene heating plate provided in the inner cavity of the heating box, a motor fixedly installed on the right side of the desulfurization box, a rotating rod fixedly connected to the output end of the motor, a stirring blade fixedly connected to the surface of the rotating rod, an adsorption box fixedly connected to the left side of the top of the desulfurization box, the adsorption box and the desulfurization box are connected by an air pipe, a slide fixedly connected to the left side of the bottom of the inner cavity of the adsorption box, an activated carbon adsorption plate slidably connected to the slide, a leakage plate fixedly connected to the right side of the inner cavity of the adsorption box, an activated carbon adsorption block placed on one side of the leakage plate, and an air outlet provided on the left side of the adsorption box.

[0006] Using the above scheme, a certain proportion of carbon black and sulfuric acid are transported to the inner cavity of the desulfurization box, and then heat is released through the graphene heating plate, and the heat is transferred to the inside of the desulfurization box. When the temperature inside the desulfurization box rises, the concentration of sulfuric acid will also increase, and the driving force of the reaction will increase, which is more conducive to the progress of the chemical reaction. At the same time, the motor drives the rotating rod to rotate, and the rotating rod drives the stirring blade to rotate, so that the sulfuric acid and carbon black are evenly mixed, and the carbon black is pickled, thereby reducing the dust and sulfur content on the carbon black and improving the quality of the carbon black. Finally, the gas generated during the pickling process is transported to the adsorption box through the gas pipe, and the activated carbon adsorption block and activated carbon adsorption plate are used to adsorb the odor and harmful substances in the gas, thereby improving the purity of the exhaust gas and preventing the gas from being directly discharged and polluting the environment.

[0007] As a preferred embodiment of a new type of equipment for ash reduction and desulfurization of waste tire pyrolysis carbon black, a liquid injection port is opened on the right side of the top of the desulfurization box, and a sealing cover is threadedly connected to the liquid injection port.

[0008] By adopting the above solution, the sealing cover is provided to prevent gas from being output from the liquid injection port, thereby improving the sealing performance of the desulfurization box.

[0009] As a preferred embodiment of a new type of equipment for ash reduction and desulfurization of waste tire pyrolysis carbon black, a power supply box is fixedly connected to the bottom of the right side of the desulfurization box, and a battery is provided in the inner cavity of the power supply box.

[0010] By adopting the above solution, the battery is provided to supply power to the electrical equipment to maintain the normal operation of the electrical equipment.

[0011] As a preferred embodiment of a new type of equipment for ash reduction and desulfurization of waste tire pyrolysis carbon black, both sides of the bottom of the desulfurization box are fixedly connected to support plates, and the bottom of the support plates is fixedly connected to a bottom plate.

[0012] By adopting the above solution, the use height of the desulfurization box can be adjusted by setting the support plate, so as to prevent the desulfurization box from being in contact with the ground for a long time, thereby preventing moisture from returning.

[0013] As a preferred embodiment of a new type of equipment for ash reduction and desulfurization of waste tire pyrolysis carbon black, one end of the stirring blade is fixedly connected to a scraper, and the number of the scrapers is two.

[0014] By adopting the above scheme, the scraper is driven to rotate by the stirring blade, and the carbon black remaining on the inner wall of the desulfurization box is repeatedly scraped off by the scraper to prevent the occurrence of residue and achieve the purpose of self-cleaning.

[0015] As a preferred embodiment of a new type of equipment for ash reduction and desulfurization of waste tire pyrolysis carbon black, one end of the rotating rod is movably connected to a bearing, and one side of the bearing is fixedly connected to the left side of the desulfurization box cavity.

[0016] By adopting the above solution and setting the bearing, it is possible to prevent one end of the rotating rod from being suspended in the air, thereby preventing the rotating rod from shaking during operation.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The gas generated during the pickling process of the utility model is transported to the adsorption box through the gas pipe, and the odor and harmful substances in the gas are adsorbed by the activated carbon adsorption block and the activated carbon adsorption plate, thereby improving the purity of the exhaust gas and preventing the gas from being directly discharged and causing pollution to the environment.

[0019] 2. The utility model transports a certain proportion of carbon black and sulfuric acid to the inner cavity of the desulfurization box, and then releases heat through the graphene heating plate and conducts the heat to the inside of the desulfurization box. When the temperature inside the desulfurization box rises, the concentration of sulfuric acid will also increase, and the driving force of the reaction will increase, which will be more conducive to the progress of the chemical reaction. At the same time, the motor drives the rotating rod to rotate, and the rotating rod drives the stirring blade to rotate, so that the sulfuric acid and carbon black are evenly mixed, and the carbon black is pickled, thereby reducing the dust and sulfur content on the carbon black and improving the quality of the carbon black.
