Description

Technical Field

[0001] This utility model relates to the field of carbon black production technology, specifically to a fine powder filtration device for carbon black production. Background Technology

[0002] Carbon black is an amorphous carbon, generally a light, loose, and extremely fine black powder with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances (coal, natural gas, heavy oil, fuel oil, etc.) under insufficient air conditions. It can be used as a black dye in the manufacture of Chinese ink, ink, and paint, and also as a reinforcing agent for rubber. In the production process of carbon black, filtration devices are often used to filter the carbon black. However, in actual use, the filter screens of existing filtration devices are mostly fixed and not easy to disassemble, making it inconvenient to clean the filter screens, which is detrimental to their use. Therefore, a fine powder filtration device for carbon black production is proposed. Utility Model Content

The vibration motor 11 can be of model YZS-75-6. The vibration motor 11 is connected to an external main controller and 220V AC mains power. The main controller can be a computer or other conventional known control device.

[0022] The inner wall of the box 7 has mounting grooves 12 on both the left and right sides. A mounting frame 13 is movably installed between the two mounting grooves 12, with one end tightly fitted to the rear side of the inner wall of the box 7. The filter screen 14 is fixedly installed inside the top of the mounting frame 13. A sealed box door 15 is movably installed on the front side of the box 7, with one end tightly fitted to the front side of the mounting frame 13.

[0023] Rectangular blocks 16 are fixedly installed on both the left and right sides of the housing 7, located above the vibration motor 11. Rectangular slots 17 are opened on the opposite sides of the two rectangular blocks 16. A first threaded rod 18 is movably installed on the opposite sides of the two rectangular blocks 16, with one end extending into the interior of the two rectangular slots 17 respectively. A round hole is opened on the opposite sides of the two rectangular blocks 16, and a first bearing is fixedly installed inside the two round holes. The first threaded rod 18 is rotatably connected to the rectangular block 16 through the first bearing. A first handwheel 19 is fixedly installed on the opposite sides of the two first threaded rods 18. Fixing slots 20 are opened on both the left and right sides of the mounting frame 13. Fixing blocks 21 are movably installed inside the two rectangular slots 17, with one end threadedly connected to the outside of the two first threaded rods 18 respectively and the other end extending into the interior of the two fixing slots 20 respectively. Threaded slots that are adapted to the two first threaded rods 18 are opened on the opposite sides of the two fixing blocks 21 respectively. A first through hole that is adapted to the fixing block 21 is opened on both the left and right sides of the housing 7.

[0024] Each of the two fixed blocks 21 has a positioning groove 22 on its top. Each of the two rectangular blocks 16 has a positioning component 23 fixedly installed on its top, with one end extending into the two positioning grooves 22 respectively. The positioning component 23 includes a housing 231. Each of the two rectangular blocks 16 has a housing 231 fixedly installed on its top. Each of the two housings 231 has a slider 232 movably installed on its bottom. Each of the two sliders 232 has a positioning block 233 fixedly installed on its bottom, with one end extending into the two positioning grooves 22 respectively. Each of the two housings 231 has a second through hole that matches the positioning block 233. The top of each of the two rectangular blocks 16 is provided with a third through hole that matches the positioning block 233. The top of each of the two housings 231 is threaded with a second threaded rod 234 that extends into its interior and is movably connected to the top of each of the two sliders 232. The top of each of the two housings 231 is provided with a threaded hole that matches the two second threaded rods 234. The top of each of the two sliders 232 is fixedly mounted with a second bearing. The second threaded rod 234 is rotatably connected to the top of the slider 232 through the second bearing. The top of each of the two second threaded rods 234 is fixedly mounted with a second handwheel 235.

[0025] In use, carbon black is injected into the chamber 7 through the feed hopper 8, causing it to accumulate on top of the filter screen 14. Then, the two vibration motors 11 are activated to vibrate the entire chamber 7, thereby improving filtration efficiency. The filtered carbon black powder is then discharged through the discharge pipe 9. During filtration, a vacuum cleaner can be used to clean the inside of the chamber 7. When cleaning the filter screen 14, the two second handwheels 235 are turned to rotate the two second threaded rods 234, which in turn rotate the two sliders 232 and... The two positioning blocks 233 move upwards, so that the two positioning blocks 233 move out of the two positioning grooves 22 respectively, thereby releasing the position restriction on the two fixing blocks 21. Then, the two first handwheels 19 can be turned to drive the two first threaded rods 18 to rotate, thereby driving the two fixing blocks 21 to move in opposite directions, so that the two fixing blocks 21 move out of the two fixing grooves 20 respectively, thereby releasing the fixation on the mounting frame 13. At this time, the sealing box door 15 can be opened, and the mounting frame 13 can be pulled forward to remove the filter screen 14, thus facilitating the cleaning operation of the filter screen 14.

[0026] In summary, this fine powder filtration device for carbon black production rotates two second threaded rods 234 by turning two second handwheels 235, thereby moving two sliders 232 and two positioning blocks 233 upwards. This causes the two positioning blocks 233 to move out of the two positioning slots 22, thus releasing the positional restriction on the two fixed blocks 21. Then, turning two first handwheels 19 rotates two first threaded rods 18, causing the two fixed blocks 21 to move in opposite directions, moving them out of the two fixing slots 20. This releases the fixation on the mounting frame 13. At this point, opening the sealed door 15 and pulling the mounting frame 13 forward allows the filter screen 14 to be disassembled. This achieves the goal of easily disassembling the filter screen 14, facilitating cleaning and solving the problem that existing filtration devices often have fixed filter screens that are difficult to disassemble, making cleaning inconvenient and hindering usability.
