Description

Technical Field

[0001] This utility model belongs to the field of pyrolytic carbon black treatment technology, and in particular relates to a pyrolytic carbon black iron remover. Background Technology

[0002] Waste tire pyrolysis refers to the process of breaking down the organic matter in waste tires at high temperatures under an oxygen-free or oxygen-deficient atmosphere. During incomplete thermal degradation, gaseous, liquid, and solid products are formed. This method can completely decompose waste tires into useful products such as pyrolysis oil, pyrolysis carbon black, and pyrolysis non-condensable gases. Pyrolysis carbon black is the second largest product of tire pyrolysis; however, the coarse carbon black produced after pyrolysis contains approximately 3% fine steel wire. If these fine steel wires are not removed, they will not only reduce the purity of the carbon black product but also damage equipment during subsequent grinding processes.

[0003] Therefore, before carbon black enters the grinding mill, pretreatment processes such as magnetic separation must be used to remove metal impurities such as steel wire. However, existing magnetic separation devices are not effective at removing tiny ferromagnetic impurities, resulting in low purity of pyrolytic carbon black. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. 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.

[0029] This utility model embodiment provides a pyrolysis carbon black iron removal device. Figure 1 This is a schematic diagram of the structure of a pyrolytic carbon black iron remover according to an embodiment of the present invention. (Reference) Figure 1 As shown, the pyrolytic carbon black iron remover includes a rotary iron remover 1.

[0030] A rotary iron separator 1 includes a housing 101, which has a pyrolytic carbon black inlet, a pyrolytic carbon black outlet, and a metal impurity outlet. The pyrolytic carbon black inlet is used to input pyrolytic carbon black into the housing 101, the pyrolytic carbon black outlet is used to output the pyrolytic carbon black (with metal impurities removed) from the housing 101, and the metal impurity outlet is used to output metal impurities.

[0031] A rotary iron separator 1, such as Figure 2 , 3 As shown, it includes an iron removal assembly, which is located inside the housing 101, as... Figure 4 As shown, the assembly includes: a plurality of magnetic rods 102 arranged in parallel at intervals; a plurality of guide sleeves 103, each guide sleeve 103 corresponding to a magnetic rod 102 and coaxially connected to one end of the magnetic rod 102, the guide sleeves 103 being non-magnetic and unable to attract metal impurities; two fixed perforated plates 104, respectively fixedly connected to the other end of the magnetic rods 102 and the other end of the guide sleeves 103 away from the magnetic rods 102; and a first driving component connected to the iron removal assembly and driving the iron removal assembly to rotate. By setting multiple magnetic rods 102, and ensuring that the multiple magnetic rods 102 and the iron removal assembly rotate as a whole, it is guaranteed that the metal impurities in the pyrolysis carbon black containing metal impurities entering the housing 101 can be fully attracted by the magnetic rods 102.

[0032] A rotary iron separator 1, such as Figure 5-8 As shown, the device includes a scraping assembly, comprising: a scraper 106 with several guide holes for the magnetic rod 102 to pass through; and a second driving member that drives the scraper 106 to reciprocate from one end of the magnetic rod 102 to the other to remove the metal impurities adsorbed by the magnetic rod 102. After the magnetic rod 102 is saturated with metal impurities, the scraper 106 moves from the end of the magnetic rod 102 away from the guide sleeve 103 to the end closer to the guide sleeve 103, thereby pushing the metal impurities to the guide sleeve 103. Since the guide sleeve 103 is non-magnetic, the metal impurities fall into the metal impurity outlet, achieving sufficient separation of the pyrolytic carbon black and metal impurities, ensuring the iron removal effect and the purity of the obtained pyrolytic carbon black.

[0033] Continue as Figure 5-8As shown, the second driving component includes: a cylinder 107, located outside the housing 101, with the linear motion direction of the piston rod of the cylinder 107 parallel to the magnetic rod 102; a sliding groove 108, formed on the housing 101 along the linear motion direction of the piston rod of the cylinder 107; and a transmission component, passing through the sliding groove 108, with one end connected to the piston rod of the cylinder and the other end connected to the unloading scraper 106. In some embodiments, the transmission component includes a transmission rod 109 and a rotary bearing 110 located at one end of the transmission rod 109; the transmission rod 109 passes through the sliding groove 108, with one end connected to the piston rod of the cylinder and the other end connected to the unloading scraper 106 via the rotary bearing 110; the outer periphery of the rotary bearing 110 is tangent to the outer edge of the unloading scraper 106. In some embodiments, the transmission component further includes friction bearings 111 located at one end of the transmission rod 109 and on the upper and lower sides of the unloading scraper 106, with the friction bearings 111 in contact with the surface of the unloading scraper 106.

[0034] In some embodiments, the first drive component includes a geared motor 105, a coupling connected to the geared motor 105, and a drive shaft connected to the geared motor 105 via the coupling, the drive shaft being fixedly connected to the fixed hole plate 104.

[0035] To ensure smooth material flow and purity of output material, magnetic rods 102 are installed at the pyrolytic carbon black inlet and outlet, and guide sleeves 103 are installed at the metal impurity outlet.

[0036] The coarse carbon black powder material enters the pyrolysis carbon black inlet of the pipeline direct-through rotary iron separator 1 from the conveying pipeline. The pyrolysis carbon black inlet is located on the left side of the housing 101 of the pipeline direct-through rotary iron separator 1.

[0037] The pipeline-connected rotary iron separator 1 has a high-intensity magnetic annular grid assembly inside its housing 101. This assembly consists of six high-intensity magnetic rods 102, evenly distributed in a circular pattern. The assembly has an upper fixing plate 104 at the top, a lower fixing plate 104 at the bottom, and a drive shaft in the middle. The six high-intensity magnetic rods 102 and a lower guide sleeve 103 connect them into a single unit. The high-intensity magnetic annular grid assembly is a device that generates a strong magnetic field. The six permanent magnet rods 102, when combined, can produce a magnetic field strength of up to 13,000 Gauss. The function of the six high-intensity magnetic rods 102 is to adsorb ferromagnetic impurities in the coarse carbon black powder onto the magnetic poles, thereby achieving iron removal.

[0038] The aforementioned rotary iron separator 1 is divided into two parts: the upper part consists of 6 high-magnetic rods 102, and the lower part consists of a guide sleeve 103. Both parts are made of non-magnetic 304 stainless steel. Each part consists of a high-magnetic rod 102 on the upper part and a non-magnetic guide sleeve 103 on the lower part. The two parts are connected by threads to form a whole.

[0039] The scraper 106 is provided with guide holes, through which six high-magnetic rods 102 and guide sleeves 103 are inserted to move up and down. The scraper 106 is made of 304 stainless steel and is connected to transmission rods 109 at 90° and 270°. The upper left and right ends of the housing 101 are provided with cylinder 107 mounting seats. The left and right scraper 106 cylinders 107 and the right scraper 106 cylinders 107 are fixed on the left and right cylinder 107 mounting seats. The left and right cylinders 107 are connected to the transmission rods 109.

[0040] The housing 101 has unloading scraper 106 grooves 108 on both sides of the center. The transmission rod 109 has push rod connection holes for the unloading scraper 106 slide rail cylinder 107, connecting to the left and right unloading scraper 106 cylinders 107. The transmission rod 109 is equipped with an axial coaxial rotary drive bearing, and the unloading scraper 106 slide rail is equipped with upper and lower friction synchronous rotary bearings 110. The second drive component drives the unloading scraper 106 to coaxially rotate.

[0041] When the six high-magnetic rods 102 on the high-strength magnetic ring grid assembly reach saturation in attracting iron, an iron unloading operation is required. The left unloading scraper 106 and the right unloading scraper 106 cylinder 107 operate up and down repeatedly to push the saturated ferromagnetic impurities attracted on the six high-magnetic rods 102 vertically downwards to the lower part of the guide sleeve 103. The ferromagnetic impurities are unloaded into the bottom of the box 101, completing the iron unloading operation.

[0042] To prevent bridging and blockage of coarse carbon black powder when it flows through the straight-through rotary iron separator 1, the straight-through rotary iron separator 1 is equipped with a drive reduction motor 105. Through a coupling, upper bearing seat, and lower bearing seat, the motor drives the high-strength magnetic ring grid assembly (iron removal component) to rotate, so that the powder is subjected to shear centrifugal force in the magnetic field, thus maintaining its fluidity and uniformity.

[0043] In some embodiments, the rotary iron separator 1 is connected to the crude carbon black buffer silo 5 through the pyrolysis carbon black inlet. The crude carbon black after pyrolysis is fed into the crude carbon black buffer silo 5 for buffering. The feed inlet of the crude carbon black buffer silo 5 is located on the left side of the silo top, and a dust collector is installed on the right side of the silo top. The dust collector on the silo top can release the air that enters the silo.

[0044] A loading level gauge is installed on the upper right side of the crude carbon black buffer silo 5, which is interlocked with the external crude carbon black conveying device to control the loading level inside the silo. A discharging level gauge is installed on the lower left conical body of the crude carbon black buffer silo 5, which is interlocked with the rear high-pressure blower 2 to control the discharging level inside the silo.

[0045] An air hammer is installed in the center of the lower conical part of the coarse carbon black buffer silo 5. The vibration of the air hammer can help to clear the silo, ensure the smooth flow of material, and avoid silo blockage.

[0046] The discharge port of the crude carbon black buffer silo 5 is located at the bottom of the silo body and is connected to the discharge valve. The discharge valve outlet is connected to a powder flow control valve, which is used to regulate the material flow rate entering the pipeline direct-connect rotary iron separator 1.

[0047] In some embodiments, the pyrolytic carbon black separator further includes a blower 2 connected to the pyrolytic carbon black outlet via a pipe, and a collection hopper 3 connected to the rotary separator 1 via the blower 2. In some embodiments, the collection hopper 3 is connected to a negative pressure blower 4. In some embodiments, the rotary separator 1 is connected to an iron unloading screw conveyor 6 via a metal impurity outlet.

[0048] The bottom of the straight-through rotary magnetic separator 1 is equipped with an iron discharge port (metal impurity outlet), which is connected to the feed inlet of the iron discharge screw conveyor 6. A drive unit is located on the right side of the iron discharge screw conveyor 6, and a discharge port is also located on the right side. The powder discharged from the pyrolytic carbon black outlet of the straight-through rotary magnetic separator 1 is drawn and conveyed to the powder conveying pipeline by the high-pressure blower 2. A flow control valve is installed on the conveying pipeline, and the powder enters the collection silo 3. A pulse control valve is located on the left side of the collection silo 3, and a negative pressure blower 4 is located on the upper right side of the collection silo 3. The powder discharge port is located at the bottom of the silo.

[0049] The working process of the above-mentioned pyrolysis carbon black iron remover is as follows:

[0050] The pyrolysis carbon black containing metallic impurities is fed into the pyrolysis carbon black inlet box 101. Under the action of multiple rotating magnetic rods 102, the metallic impurities are fully adsorbed onto the magnetic rods 102. After the magnetic rods 102 are saturated with metallic impurities, the scraper 106 moves from the end of the magnetic rods 102 away from the guide sleeve 103 to the end closer to the guide sleeve 103, thereby pushing the metallic impurities to the guide sleeve 103. Since the guide sleeve 103 is non-magnetic, the metallic impurities fall into the metallic impurity outlet box 101. At the same time, the pyrolysis carbon black with metallic impurities removed is discharged through the pyrolysis carbon black outlet box 101, thus achieving a complete separation between the pyrolysis carbon black and the metallic impurities.

[0051] The advantages of using the above-mentioned pyrolysis carbon black iron remover to remove metallic impurities from pyrolysis carbon black are as follows:

[0052] 1. High-efficiency iron removal capability: The rotary carbon black iron remover generates a strong magnetic field through the built-in rotating magnet, which can effectively adsorb tiny ferromagnetic impurities and ensure the purity of the material.

[0053] 2. Easy to maintain: Regular cleaning and inspection can ensure its long-term stable operation, and the maintenance cost is relatively low.

[0054] 3. High adaptability: It is suitable for various material handling scenarios, including powders and granular materials with good flowability as well as materials with poor flowability.

[0055] 4. Improve production efficiency: Through efficient iron removal capabilities, downtime and scrap rates during the production process are reduced, thereby improving overall production efficiency.

[0056] 5. Ensure production safety: Its strong magnetic field adsorption capacity can ensure that iron impurities in materials are completely removed, avoiding equipment failures and safety accidents caused by impurities.

[0057] In summary, the rotary carbon black iron separator generates a strong magnetic field through its built-in rotating magnet. When the material flows through the separator, iron impurities are firmly adsorbed onto the rotating magnet by the magnetic force. As the magnet rotates, when the adsorption becomes saturated, the upper cylinder 107 drives the iron discharge scraper 106 to discharge the adsorbed iron to the iron discharge point. Finally, the iron impurities are separated from the magnet and discharged, ensuring the purity of the material.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
