Description

Technical Field

[0001] This invention relates to the field of carbon black production technology, specifically to a magnetic separation device for carbon black materials. Background Technology

[0002] Carbon black is an amorphous carbon, a light, loose, and extremely fine black powder with a very large surface area, ranging from 10 to 3000 m². 2 Carbon black ( / g) is a product obtained from the incomplete combustion or thermal decomposition of carbon-containing substances under insufficient air conditions. The structure of carbon black is expressed as the degree to which carbon black particles aggregate into chain-like or grape-like structures. The aggregate composition, consisting of the size, morphology, and number of particles in each aggregate, is called the structure of carbon black. The oil absorption value is commonly used to represent the structure of carbon black; the higher the oil absorption value, the higher the structure of the carbon black, the easier it is to form spatial network channels, and the less easily it is destroyed. Carbon black has many excellent properties, such as high specific surface area, high adsorption capacity, and excellent electrical conductivity, and therefore is widely used in many fields.

[0003] Carbon black production equipment is mostly made of ferrous metals. Over time, corrosion and wear occur, leading to iron filings mixing into the carbon black product. This reduces the quality of the carbon black and may even damage equipment used later. Therefore, it is necessary to remove iron impurities from the carbon black. However, existing iron impurity removal devices are insufficient because the magnetic rods are inadequate to completely adsorb and remove iron impurities from the thick carbon black layer. To address this, a new method for removing iron impurities from carbon black materials is designed.

[0004] Magnetic separation equipment. Additionally, carbon black can also adsorb onto iron impurities, leading to a waste of carbon black. Summary of the Invention

[0005] The present invention provides a magnetic separation device for carbon black materials to solve at least one of the technical problems mentioned above.

[0006] To solve the above-mentioned technical problems, the present invention discloses a magnetic separation device for carbon black materials, including a closed shell, a feed inlet at the top of the closed shell, a first vibrating screen fixed below the feed inlet, a first magnetic roller fixed below the outlet of the first vibrating screen, a distributor fixed below the first magnetic roller, a second magnetic roller fixed below the distributor, an iron outlet and a material outlet below the second magnetic roller, and a dust removal port above and in front of the outlet of the first vibrating screen; a drive motor is located directly below the first vibrating screen.

[0007] Preferably, the iron outlet is provided with a collision groove, and there is an opening on one side of the bottom of the collision groove. A second vibrating screen is provided below the opening, and a third magnetic roller is provided below one side of the second vibrating screen. An iron part outlet and a carbon black powder collection outlet are respectively provided below the third magnetic roller.

[0008] Preferably, the drive motor is located outside the enclosed housing of the equipment. The drive motor's drive shaft is connected to the first rotating shaft of the first magnetic roller via a belt. The first rotating shaft is connected to the second rotating shaft of the second magnetic roller and the third rotating shaft of the third magnetic roller via belts.

[0009] Preferably, the first rotating shaft, the second rotating shaft, and the third rotating shaft pass through the closed housing of the equipment and are connected to the first magnetic roller, the second magnetic roller, and the third magnetic roller, respectively.

[0010] Preferably, the first vibrating screen includes a vibrating platform, the bottom of which is connected to four electric vibrating devices. The vibrating platform is tilted at an angle of 15-18°.

[0011] Preferably, the inclination angle of the second vibrating screen is 10-12°.

[0012] Benefits: Under the magnetic force of the internal magnetic sources of the first, second, and third magnetic rollers, the magnetic material in the carbon black powder is removed, separating the carbon black powder adsorbed on the magnetic material. This improves product quality and production efficiency, saves resources, reduces labor costs, and avoids potential equipment damage. However, since some carbon powder remains adsorbed on the separated magnetic material, especially during the initial separation, the addition of a collision groove structure allows for further separation of the carbon black powder from the magnetic material through collision, making collection more efficient and preventing waste.

Detailed Implementation

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] The present invention provides the following embodiments.

[0021] This invention provides a magnetic separation device 100 for carbon black materials, such as... Figure 1-3 As shown, the device includes a closed housing 100. A feed inlet 1 is provided at the top of the closed housing 100. A first vibrating screen 2 is fixed below the feed inlet 1. A first magnetic roller 6 is fixed below the outlet of the first vibrating screen 2. A distributor 3 is fixed below the first magnetic roller 6. A second magnetic roller 7 is fixed below the distributor 3. An iron outlet 9 and a material outlet 8 are located below the second magnetic roller 7. There is a dust removal port 5 above and in front of the outlet of the first vibrating screen 2. A drive motor 4 is provided directly below the first vibrating screen 2. The drive motor 4 is located outside the closed housing 100. The drive shaft 41 of the drive motor 4 is connected to the first rotating shaft 61 of the first magnetic roller 6 via a belt. The first rotating shaft 61 is connected to the second rotating shaft 71 of the second magnetic roller 7 and the third rotating shaft 941 of the third magnetic roller 94 via belts. In this way, the drive motor 4 drives the magnetic rollers to rotate simultaneously.

[0022] The first rotating shaft 61, the second rotating shaft 71, and the third rotating shaft 941 penetrate the equipment's enclosed outer casing 100 and are respectively connected to the first magnetic roller 6, the second magnetic roller 7, and the third magnetic roller 94. The penetration points are sealed to ensure that carbon black does not leak out from the inside.

[0023] The first vibrating screen 2 includes a vibrating platform 21. The bottom of the vibrating platform 21 is connected to four electric vibrating devices 22. The vibrating platform 21 is set at an inclination angle of 15-18°. The electric vibrating devices 22 are conventional devices, and their function is to vibrate up and down.

[0024] The iron outlet 9 is provided with a collision groove 91. There is an opening 92 on one side of the bottom of the collision groove 91. Below the opening 92, a second vibrating screen 93 is provided. The second vibrating screen 93 has the same structure as the first vibrating screen 2, except that the second vibrating screen 93 is tilted at an angle of 10-12°. A third magnetic roller 94 is provided below one side of the second vibrating screen 93. Below the third magnetic roller 94, an iron part outlet 95 and a carbon black powder collection outlet 96 are respectively provided.

[0025] The first magnetic roller 6 is composed of strong magnets and an iron core to generate sufficient magnetic force to attract magnetic substances in the material onto the magnetic roller.

[0026] The dust generated during the conveying and separation of iron filings by carbon black is sucked away by the dust collection port to prevent dust from flying and polluting the on-site environment.

[0027] The working principle of the above technical solution is as follows: Carbon black material is fed into the first vibrating screen 2 through the feed port 1. The vibration makes the carbon black material evenly distributed and flow forward. Then it passes through the first magnetic roller 6 driven by the drive motor 4. Under the magnetic force of the first magnetic roller 6, the magnetic material in the carbon black powder is adsorbed on the magnetic roller. As the first magnetic roller 6 rotates, the magnetic material leaves the magnetic force range of the magnetic source on the magnetic roller and falls into the slag discharge port 9 after passing through the distributor 3. The remaining carbon black powder falls onto the second magnetic roller 7 in front of the distributor. The second magnetic roller 7 will further adsorb any remaining magnetic material in the carbon black powder. As the second magnetic roller 7 rotates, the magnetic material will pass through the slag discharge port 9. The processed carbon black powder will be fed into the silo through the discharge port 8.

[0028] The magnetic material after passing through the first magnetic roller 6 and the second magnetic roller 7 falls into the collision groove 9 of the slag discharge port 9. Since the magnetic material is far from the collision groove 9 after passing through the first magnetic roller 6, it will collide with the bottom magnetic material. This collision between the magnetic materials can separate the adsorbed carbon black powder. Since the bottom of the collision groove 9 is inclined at 8°, the magnetic material is discharged through the bottom opening 92 onto the second vibrating screen 93, where it is further separated by the action of the third magnetic roller 94.

[0029] The advantages of this invention are as follows: Under the magnetic force of the magnetic source inside the first magnetic roller 6, the second magnetic roller 7, and the third magnetic roller 94, the magnetic material in the carbon black powder is removed. In addition, the collision groove 9 is set up to further separate the carbon black powder adsorbed on the magnetic material, thereby improving product quality and production efficiency, saving resources, reducing labor costs, and avoiding potential damage to the equipment.

[0030] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
