Description

Technical Field

[0001] The utility model belongs to the technical field of waste rubber and plastic pyrolysis and iron removal from various powder materials containing iron, and particularly relates to a hanging type pyrolytic carbon black iron removal device. Background Technique

[0002] The thermal cracking of waste tires refers to an irreversible thermal chemical reaction in an anaerobic or anoxic atmosphere, in which the organic matter in waste tires is cracked by high temperature, volatile products are released, and solid coke is formed. Gas, liquid and solid products can be formed in the incomplete thermal degradation process. By using this method, waste tires can be completely cracked into useful products. The thermal cracking of waste tires is a relatively popular method for treating waste tires at present, and waste tires can be cracked into tire oil, carbon black, steel wire and combustible gas. Among them, carbon black accounts for 30%-35% in the products and is the second largest product of tire cracking. The main component of carbon black is carbon, and at the same time, it contains a small amount of elements such as steel wire, hydrogen, oxygen, nitrogen, etc. The carbon black after the thermal cracking of waste tires is in the form of black powder solids, also known as "crude carbon black", which can be recycled. After proper treatment and reasonable processing and utilization, carbon black has high economic value, can enhance the product strength, durability and coloring performance of rubber, and is therefore often used as a raw material, used as a reinforcing agent and filler of rubber products, etc., and is applied to many rubber products such as vehicle tires.

[0003] Waste tires contain about 30% steel wire. Before the thermal cracking of waste tires, first, the waste tires are separated by mechanical treatment through mechanical methods, such as using equipment such as crushers, magnetic separators, vibrating screens, etc., to break the waste tires into rubber particles of a certain size, and separate the rubber particles and steel wire through different vibration frequencies and sieve hole sizes. However, the tire fragments treated by the above methods still contain about 3-5% fine steel wire, and enter the pyrolysis furnace along with the conveying equipment, and are mixed with carbon black after cracking. If not removed, it will affect the quality of carbon black in the later stage. Summary of the Utility Model

[0025] The above-mentioned hanging type iron removal device for pyrolytic carbon black realizes the removal of steel wires during the transportation of pyrolytic carbon black by setting the iron removal component 2. At the same time, by defining the relationship between the running direction of the steel wire conveyor belt 203 at the first position and the conveying member, and the positional relationship among the permanent magnet body 201, the steel wire conveyor belt 203 at the first position and the conveying member, the removal efficiency of the steel wires mixed in the pyrolytic carbon black is improved.

[0033] Regarding the suspended pyrolytic carbon black iron removal device, specifically:

[0034] The crude carbon black separated after the pyrolysis of waste rubber and plastics is discharged into the feed inlet of the crude carbon black conveying screw conveyor 3 through the discharge opening of the rear sealing bin and discharged from the discharge outlet of the crude carbon black conveying screw conveyor 3. The box body 102 of the crude carbon black pulley conveyor adopts a closed structure. The feed inlet is vertically arranged at the upper left side of the box body 102 of the crude carbon black pulley conveyor and is connected to the discharge outlet of the crude carbon black conveying screw conveyor 3. A closed crude carbon black pulley conveyor is arranged inside the box body 102 of the crude carbon black pulley conveyor. Driven rollers are arranged on the left side. The end of the frame 209 of the crude carbon black pulley conveyor is provided with driven roller adjusting bolts for adjusting the tension of the carbon black conveying belt of the crude carbon black pulley conveyor. The material entering from the discharge outlet of the crude carbon black conveying screw conveyor 3 falls onto the carbon black conveying belt of the crude carbon black pulley conveyor. Equal numbers of auxiliary supporting rollers 208 with different quantities are arranged on the frame 209 of the crude carbon black pulley conveyor to assist the operation of the carbon black conveying belt of the crude carbon black pulley conveyor. In addition, belt scrapers are provided to prevent slipping when conveying materials and increase the friction force. On the upper right side of the box body 102 of the crude carbon black pulley conveyor, a No. 1 suspended iron remover body is arranged to remove the residual steel wires in the crude carbon black by using the permanent magnet body 201 of the iron remover. The No. 1 suspended iron remover body is erected on the upper part of the box body 102 of the crude carbon black pulley conveyor by using the No. 1 suspended iron remover bracket. Lifting lugs are arranged on the suspended iron remover bracket, and 4 No. 1 suspended chains 211 are symmetrically arranged on the left and right for suspension to prevent the vibration of the No. 1 suspended iron remover body from affecting the magnetic attraction effect. In order to further improve the reliability of iron removal, on the basis of the original No. 1 suspended iron remover body, a No. 2 suspended iron remover body is additionally installed at its rear. The No. 2 suspended iron remover body is also erected on the upper part of the box body 102 of the crude carbon black pulley conveyor by using the No. 2 suspended iron remover bracket. Lifting lugs are arranged on the suspended iron remover bracket, and 4 No. 2 suspended chains 211 are symmetrically arranged on the left and right for suspension. The purpose is also to prevent the vibration of the No. 2 suspended iron remover body from affecting the magnetic attraction effect.

[0035] A maintenance door is provided at the rear right side of the housing 102 of the coarse carbon black pulley conveyor, which is used to conveniently adjust the adjusting bolts of the driving roller. A driving roller is provided at the right end of the frame 209 of the coarse carbon black pulley conveyor. An adjusting bolt is provided on the right side of the driving roller, which is used to adjust the tension of the carbon black conveyor belt of the coarse carbon black pulley conveyor. The driving roller and the driven roller operate in cooperation, and a driving reduction motor is provided on the driving roller to drive the operation of the coarse carbon black pulley conveyor. A blanking port is vertically provided at the lower right side of the housing 102 of the coarse carbon black pulley conveyor.

The steel wire conveyor belt rotates counterclockwise. A permanent magnet body 201 of a strong magnetic iron remover is provided in the lower frame of the iron remover frame 209. When the coarse carbon black conveyed by the carbon black conveyor belt of the coarse carbon black pulley conveyor contains iron, it will be attracted by the permanent magnet body 201 of the iron remover, and the iron will move to the right along with the steel wire conveyor belt. When the steel wire conveyor belt moves to the iron discharge port (steel wire blanking port 202) of the iron remover, the iron adsorbed on the steel wire conveyor belt will break away from the permanent magnet body 201 of the iron remover and fall into the steel wire blanking port 202 for recovery. The steel wire conveyor belt runs cyclically to remove iron such as steel wires in the coarse carbon black and ensure the quality during the next step of carbon black deep processing.

[0038] On the upper part of the iron remover frame 209, there are left suspension lugs and right suspension lugs vertically arranged, and they are symmetrically arranged on the left and right to hoist the suspended iron remover assembly onto the iron remover fixing frame 210 for fixation.

The iron remover driving reduction motor is arranged on the right driving wheel drum 207. There is an adjusting device on the driving drum 207, and there is also an adjusting device on the driven drum 207 for adjusting the tension of the steel wire conveyor belt. At the lower part of the iron remover fixing frame 210, there is an iron remover permanent magnet body 201, which is fixed at the lower part of the iron remover fixing frame 210 to adsorb the iron in the coarse carbon black. There is an iron unloading running belt scraper on the steel wire conveyor belt, and it runs after the auxiliary supporting wheel 2081, the auxiliary supporting wheel 2082, the driving wheel drum 207, and the driven wheel drum 207. There is a steel wire blanking port 202 suspended on the lower right side of the iron remover fixing frame 210, and the iron adsorbed on the steel wire conveyor belt is unloaded into the lower collection box for caching.

[0039] The above device uses the multi-stage magnetic separation method to magnetically separate the coarse carbon black before grinding, and separates the rubber impurities containing steel wires through the action of the magnetic field. This method can remove the remaining steel wires in the coarse carbon black by 100%, and has the advantages of simple structure, convenient installation, and good use effect.

[0040] Advantages of the suspended iron remover:

[0045] The working process of the above-mentioned suspended pyrolytic carbon black iron remover is as follows:

[0046] When the pyrolytic carbon black conveyed on the conveyor contains steel wires and iron impurities, the steel wires and iron impurities are adsorbed on the first-position steel wire conveyor belt 203 running above the conveyor under the magnetic attraction of the permanent magnet body 201, and are output through the steel wire discharge port 202 under the magnetic attraction away from the permanent magnet body 201 as the first-position steel wire conveyor belt 203 conveys.
