Description

Technical Field

[0001] This utility model relates to the field of carbon black processing technology, specifically to a carbon black particle magnetic dust collection device. Background Technology

[0002] With the development of the carbon black industry, the popularization of new process equipment, and the increasingly higher requirements of the carbon black sieve residue in the product industry, the carbon black sieve residue required for high-end products in the product industry needs to reach 325 mesh 100PPM or even higher. During the production process of carbon black, due to the complex composition of carbon black flue gas, and the actual working conditions such as corrosion, high temperature, high pressure, and humidity, it is inevitable that ferrous substances from the inner wall of iron containers will be introduced into the carbon black. Therefore, it is necessary to use a magnetic separator to screen and separate ferrous impurities from carbon black.

[0003] After searching, it was found that application number CN202321321843.2, entitled "A Magnetic Separator for Carbon Black Processing," proposes a magnetic separator for carbon black processing. This separator uses an electric telescopic rod to lower the position of the grinding plate, adjusting the grinding size of the carbon black. A first servo motor drives a rotating shaft, which in turn rotates the grinding plate at the bottom of the shaft, grinding the carbon black on top of the perforated plate. This facilitates the adsorption of ferrous impurities inside the carbon black clumps, improving the magnetic separation effect. However, this application has an inlet and an outlet, with the outlet further divided into a carbon black particle outlet and an ferrous impurity outlet. This puts the entire equipment in a state of openness to the outside environment. Dust from the carbon black particles will escape along the inlet and outlet during grinding and magnetic separation, easily causing pollution to the working environment. Further improvements are needed.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a carbon black particle magnetic separation dust collection device, which has the following beneficial effects:

[0019] (1) This utility model employs a first dust collection box, a second dust collection box, and a third dust collection box. During magnetic separation of carbon black particles, the first dust collection box is installed above the feeding port of the magnetic separator, the second dust collection box is installed above the discharging port of the magnetic separator, and the third dust collection box is installed above the iron discharge port of the magnetic separator. The air pump is started to extract the air from inside the dust collection box. The air is then extracted from the first, second, and third dust collection boxes through a flexible hose, creating a negative pressure at the dust collection port. Dust generated during feeding enters the first dust collection box through the dust collection port, dust generated during discharging enters the second dust collection box, and dust generated during iron discharge enters the third dust collection box. Dust enters the third dust collection box, and then flows through a hose into the dust collection box. After being filtered by the dust filter bag, the dust remains in the dust collection box, completing the dust collection process. This device, by arranging the first, second, and third dust collection boxes, prevents dust from escaping from the feed inlet, discharge outlet, and iron outlet of the magnetic separator.

The collection box 18 has a flexible hose 10 connected to the other side surface of the dust collection box 1. Multiple hoses 10 are arranged, and their lengths are determined by the distance between the dust collection equipment and the magnetic separator. The other ends of the hoses 10 are respectively connected to a first dust collection box 11, a second dust collection box 12, and a third dust collection box 13. The dimensions of the first dust collection box 11, the second dust collection box 12, and the third dust collection box 13 are determined according to the dimensions of the feeding port, the discharging port, and the iron discharge port of the magnetic separator. Each of the first dust collection box 11, the second dust collection box 12, and the third dust collection box 13 has a suction port 14 on its bottom surface. The length of the suction port 14 is greater than the length of the feeding port, the discharging port, and the iron discharge port.

A rubber rod 7 is fixedly installed on the surface of the main shaft 6. Multiple sets of rubber rods 7 are arranged from top to bottom, and the length of the rubber rod 7 is greater than the distance between the mounting cylinder 3 and the main shaft 6, ensuring that the rubber rod 7 can strike the mounting cylinder 3. The mounting cylinder 3 is arranged in a ring, and the outer surface of the mounting cylinder 3 is fitted with a dust collector filter bag 4. Ventilation holes 19 are opened on the surface of the mounting cylinder 3 for ventilation. The mounting cylinder 3 facilitates the opening of the dust collector filter bag 4.

[0035] In one embodiment, a magnet block 15 is fixedly installed on one side surface of the first dust collection box 11, the second dust collection box 12, and the third dust collection box 13. The installation direction of the magnet block 15 is determined according to the direction of the feeding port, the discharging port, and the iron outlet of the magnetic separator. The magnet block 15 can conveniently fix the first dust collection box 11, the second dust collection box 12, and the third dust collection box 13 to the surface of the magnetic separator, which is convenient for quick installation.

[0036] In one embodiment, the collection box 18 is hinged to a cleaning door on its front facade, and the cleaning door is a sealed door to facilitate the cleaning of the collected carbon black dust.

[0037] Working principle:

[0038] During magnetic separation of carbon black particles, the first dust collection box 11 is installed above the feed inlet of the magnetic separator, the second dust collection box 12 is installed above the discharge outlet of the magnetic separator, and the third dust collection box 13 is installed above the iron outlet of the magnetic separator. The vacuum pump 8 is started, extracting air from inside the dust collection box 1. Air is then extracted from the first, second, and third dust collection boxes 11, 12, and 13 through the hose 10, creating a negative pressure at the suction port 14. Dust generated during feeding enters the third dust collection box 13 through the suction port 14. Dust generated during material discharge enters the second dust collection box 12 in the first dust collection box 11, and dust generated during iron tapping enters the third dust collection box 13. The dust then enters the dust collection box 11 through the hose 10. After being filtered by the dust filter bag 4, the dust remains in the dust collection box 11, completing the dust collection process. This device, by arranging the first dust collection box 11, the second dust collection box 12, and the third dust collection box 13, prevents dust from escaping from the feed inlet, discharge outlet, and iron tapping outlet of the magnetic separator. The second and third dust collection boxes 12 and 13 are connected to the dust collection box 1 via hoses 10, allowing for flexible and convenient arrangement. This ensures comprehensive dust collection, effectively preventing dust dispersion and environmental pollution. Furthermore, this device requires no structural modifications to existing magnetic separation equipment, making it easy to assemble, disassemble, and use. The mounting cylinders 3 are arranged in a ring, with dust filter bags 4 fitted onto their outer surfaces. Ventilation holes 19 are provided on the surface of the mounting cylinders 3 for air circulation. The mounting cylinders 3 also facilitate the opening of the dust filter bags 4. When dust adheres to the surface of the dust filter bags 4, the drive motor 5 rotates the main shaft 6, which in turn rotates the rubber rod 7. The rotating rubber rod 7 strikes the surface of the dust filter bags 4, creating vibration and shaking off the dust. The dust is then collected in the collection box 18 via the airlock unloader 17, facilitating cleaning and further improving usability. Additionally, the rubber rod 7 has low hardness, preventing structural damage to the dust filter bags 4 and mounting cylinders 3, thus extending the equipment's service life.
