Description

Technical Field

[0001] The utility model relates to the technical field of waste tire solid recovery, and more specifically, to a carbon black and steel wire separation device and a pyrolysis system. Background Art

[0002] Placing waste tires in a pyrolysis kettle for treatment to pyrolyze the organic matter on the tires can produce liquid hydrocarbon substances. The parts that cannot be pyrolyzed in waste tires, such as steel wires, carbon black, and a small amount of other fillers that cannot be pyrolyzed, are discharged from the slag discharge system of the pyrolysis kettle. Among them, both steel wires and carbon black can be recycled. Therefore, special equipment is required to separate steel wires from carbon black.

[0003] Chinese Patent Authorization Publication No.: CN210058881U provides a pyrolysis carbon black and steel wire separation device. This solution controls driving structure one and driving structure two through a PLC controller. The driving spiral conveyor shaft one and spiral conveyor shaft two can perform separation operations automatically, which is simple and convenient; the universal wheels on the moving structure can move the device to the required place to realize the mobile use of the device; the carbon black separated can be collected through a collection box, and the separated carbon black is taken out through a collection drawer and a handle. The separated steel wires can be collected and processed through a collection basket.

[0004] However, carbon black is fine powder and will be adsorbed on the surface of steel wires in large amounts under the action of static electricity. This solution only moves steel wires and carbon black uniformly through the conveyor shaft, and it is difficult to completely remove the carbon black on the surface of steel wires during the movement, resulting in poor separation effect and reducing the efficiency of the separation work. Therefore, a carbon black and steel wire separation device and a pyrolysis system are proposed for the above problems. Summary of the Utility Model

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a carbon black and steel wire separation device and a pyrolysis system. This solution sets multiple buffer plates to collide with the falling steel wires and carbon black to promote the separation of steel wires and carbon black. The steel wires are dispersed by a conveyor belt to increase the gap between the steel wires, so that the carbon black is more likely to fall off the steel wires. The conveyor belt is driven by a vibration component to vibrate, which helps the carbon black on the steel wires on the surface of the conveyor belt to fall off, and the carbon black intercepted on the surface of the conveyor belt is vibrated down through the filter holes. The steel wires on the conveyor belt are intermittently adsorbed by an electromagnet to further promote the carbon black on the steel wires to fall. A strong suction force is formed in the separation cavity by a suction fan to suck away the separated carbon black. With such settings, through multiple separation measures, it is ensured that carbon black and steel wires are separated, the separation effect is improved, and the efficiency of the separation work is increased.

[0027] Embodiment:

[0028] Please refer to Figure 1-2 , a carbon black and steel wire separation device and a pyrolysis system, including a housing 1. A separation chamber 101, a feed chamber 102, a carbon black discharge chamber 103 and a steel wire discharge chamber 104 are respectively opened in the inner cavity of the housing 1. The separation chamber 101, the feed chamber 102, the carbon black discharge chamber 103 and the steel wire discharge chamber 104 are interconnected. A carbon black collection box 2 and a steel wire collection box 3 are fixedly connected to the bottom end of the housing 1. The feed chamber 102 and the carbon black discharge chamber 103 are respectively communicated with the inner cavities of the carbon black collection box 2 and the steel wire collection box 3. A plurality of buffer plates 6 are fixedly connected to the inner wall of the feed chamber 102. A conveyor belt 7 is installed on the inner wall of the separation chamber 101. A plurality of filter holes are opened on the conveyor belt 7. An air suction fan is installed inside the carbon black collection box 2.

[0029] Place the waste tire in the pyrolysis kettle for treatment to pyrolyze the organic matter on the tire, and liquid hydrocarbon substances can be produced. The parts that cannot be pyrolyzed in the waste tire, such as steel wire, carbon black, and a small amount of other fillers that cannot be pyrolyzed, are discharged from the slag discharge system of the pyrolysis kettle. Among them, both the steel wire and the carbon black can be recycled. For this reason, special equipment is needed to separate the steel wire from the carbon black.

[0030] In this solution, carbon black and steel wires enter the feeding chamber 102 together, fall from the feeding chamber 102 into the separation chamber 101 and drop onto the conveyor belt 7. The user starts the conveyor belt 7 to drive the carbon black and steel wires to move together. At the same time, the suction fan inside the carbon black collection box 2 starts, and the air flow enters the separation chamber 101 through the feeding chamber 102 to suck the carbon black. The carbon black falls to the bottom of the conveyor belt 7 through the filter holes on the conveyor belt 7 and is sucked into the carbon black collection box 2 by the suction fan through the feeding chamber 102 for collection. The steel wires are transported to the upper part of the carbon black feeding chamber 103 by the conveyor belt 7 and finally drop into the steel wire collection box 3 through the carbon black feeding chamber 103 for collection. The purpose of setting the conveyor belt 7 is to disperse the dropped steel wires, make the steel wires disperse at the upper end of the conveyor belt 7, increase the gap between the steel wires, so that the carbon black can easily break away from the steel wires.

[0031] Please refer to Figure 2 , a plurality of buffer plates 6 are arranged in a staggered manner, and a plurality of buffer plates 6 are all inclined.

[0032] During the falling process, the carbon black and the steel wires will collide and fall on the plurality of buffer plates 6, and this collision process can promote the separation of the carbon black and the steel wires.

[0033] Please refer to Figure 3 , an electromagnet 8 is installed at the top end of the inner wall of the separation chamber 101, and a power supply 4 is installed at the outer end of the housing 1. The power supply 4 is electrically connected to the electromagnet 8.

[0034] In this solution, the power supply 4 will be started intermittently. Once the power supply 4 is started, it will make the electromagnet 8 energized. The electromagnet 8 covers the upper side of the conveyor belt 7. After being energized, the electromagnet 8 will adsorb the steel wires staying on the conveyor belt 7 to the lower end of the electromagnet 8. The process of the steel wires being adsorbed upward can promote the carbon black on the surface of the steel wires to fall off, and at the same time make only the carbon black remain on the surface of the conveyor belt 7, making it easier for the carbon black to be absorbed by the air flow. After the power is cut off, the electromagnet 8 will make the adsorbed steel wires fall back onto the conveyor belt 7 again.

[0035] Please refer to Figure 3-4 , a plurality of vibration components 9 are arranged inside the conveyor belt 7. The vibration components 9 include a pair of mounting blocks 901. The mounting blocks 901 are fixedly connected to the inner wall of the separation chamber 101, and a vibration block 902 is arranged on the upper side of the mounting blocks 901. A plurality of springs 903 are fixedly connected between the vibration block 902 and the mounting blocks 901, and a vibration pump 904 is installed at the bottom end of the vibration block 902.

[0036] In this solution, multiple vibration components 9 continuously operate. The vibration of the vibration components 9 can drive the vibration of the vibration block 902. At the same time, with the elastic force of the spring 903, the vibration block 902 continuously impacts the conveyor belt 7 above it, causing the upper surface of the conveyor belt 7 to vibrate continuously. This further drives the vibration of the steel wire at the upper end of the conveyor belt 7. This vibration process can help the carbon black on the steel wire on the surface of the conveyor belt 7 to break away, and vibrate the carbon black intercepted on the surface of the conveyor belt 7 through the filter holes, thereby reducing the carbon black carried into the carbon black feeding chamber 103 by the conveyor belt 7.

[0037] Please refer to Figure 2 , a plurality of air inlet holes 5 are opened at the outer end of the housing 1. The air inlet holes 5 are communicated with the separation chamber 101, and the bottom end of the inner wall of the separation chamber 101 is inclined.

[0038] The setting of the air inlet holes 5 facilitates the entry of external air flow into the separation chamber 101 through the air inlet holes 5, thereby promoting the formation of air convection in the inner cavity of the separation chamber 101 by the air flow generated by the suction fan, enhancing the suction force, and helping the carbon black to be absorbed more quickly. The inclined setting of the bottom end of the separation chamber 101 can make the carbon black falling on the bottom end of the separation chamber 101 slide down along the bottom end of the separation chamber 101 into the feeding chamber 102, preventing the carbon black from falling into the carbon black feeding chamber 103.

[0039] Please refer to Figure 1 , on the other hand, the present utility model also provides a pyrolysis system of a carbon black and steel wire separation device including any of the above technical solutions.

[0040] The waste tire is broken into rubber blocks, and the rubber blocks are pyrolyzed into carbon black and steel wire through a pyrolysis reactor. The discharge port of the reactor is communicated with the feeding chamber 102. The carbon black and steel wire fall into the feeding chamber 102 through the discharge port of the pyrolysis reactor, and then enter the separation chamber 101 for separation. After separation, the carbon black falls into the carbon black collection box 2, and the steel wire falls into the steel wire collection box 3.

[0041] Working principle:

[0042] In use, the waste tires are crushed into rubber blocks, and the rubber blocks are pyrolyzed into carbon black and steel wires in a pyrolysis reactor. The outlet of the reactor is connected to the feeding chamber 102. The carbon black and steel wires fall into the feeding chamber 102 through the outlet of the pyrolysis reactor. During the falling process in the feeding chamber 102, the carbon black and steel wires will collide and fall on multiple buffer plates 6. This collision process can promote the separation of carbon black and steel wires. Then, the carbon black and steel wires fall into the separation chamber 101 and drop onto the conveyor belt 7. The user starts the conveyor belt 7 to drive the carbon black and steel wires to move together. At the same time, the suction fan inside the carbon black collection box 2 is started. The air flow enters the separation chamber 101 through the feeding chamber 102, and at the same time, the outside air flow enters the separation chamber 101 through the air inlet holes 5, so as to promote the air convection formed by the air flow generated by the suction fan in the inner cavity of the separation chamber 101 to absorb the carbon black. The carbon black falls to the bottom of the conveyor belt 7 through the filter holes on the conveyor belt 7 and is sucked into the carbon black collection box 2 by the suction fan through the feeding chamber 102 for collection. The steel wires are transported to the upper part of the carbon black discharging chamber 103 through the conveyor belt 7 and finally drop into the steel wire collection box 3 through the carbon black discharging chamber 103 for collection. During the operation of the carbon black and steel wires on the conveyor belt 7, multiple vibration components 9 will continuously work. The vibration of the vibration components 9 can drive the vibration block 902 to vibrate. At the same time, with the elastic force of the spring 903, the vibration block 902 continuously impacts the conveyor belt 7 above it, so that the upper surface of the conveyor belt 7 continuously vibrates, and then drives the steel wires at the upper end of the conveyor belt 7 to vibrate. This vibration process can help the carbon black on the steel wires on the surface of the conveyor belt 7 to fall off, and vibrate the carbon black intercepted on the surface of the conveyor belt 7 through the filter holes. At the same time, the power supply 4 will be intermittently started. Once the power supply 4 is started, the electromagnet 8 will be energized. After being energized, the electromagnet 8 will adsorb the steel wires staying on the conveyor belt 7 to the lower end of the electromagnet 8. The process of the steel wires being adsorbed upward can promote the carbon black on the surface of the steel wires to fall off, and at the same time, only carbon black remains on the surface of the conveyor belt 7, making it easier for the carbon black to be absorbed by the air flow. After the power is cut off, the electromagnet 8 will make the adsorbed steel wires fall back onto the conveyor belt 7 again.

[0043] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
