Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a multi-stage filtering device for ink production. Background Art

[0002] Ink is a liquid containing pigments or dyes used for writing or painting. The earliest inks used dyes made from metals, walnut shells, or seeds, or from aquatic animals like fish and octopus. Chinese ink is carbon ink, with bituminous coal powder being a key ingredient. The coarseness of the bituminous coal powder significantly affects the ink's quality.

[0003] Some existing multi-stage filtration devices for ink production usually pour ink directly into the interior of the device and then filter it by gravity. However, since the ink contains a large amount of impurities and even clots, the filter may be clogged after a long period of filtration. At the same time, because the filter is usually fixedly installed inside the device, it is relatively complicated to clean the filtered impurities, which is inconvenient to clean and collect the filtered impurities, and has low practicality. In view of this, we propose a multi-stage filtration device for ink production to solve the above problems. Utility Model Content

[0015] 1.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-6The utility model provides a technical solution: a multi-stage filtering device for ink production, comprising a main body 1, a cavity 2 is opened inside the main body 1, a bottom plate 6 is arranged inside the cavity 2, and the upper surface of the bottom plate 6 is fixedly connected to the first filter barrel 3, the second filter barrel 4 and the third filter barrel 5. The outer surfaces of the first filter barrel 3 and the second filter barrel 4 are fixedly connected to the connecting ring 7, and the surface of the connecting ring 7 is provided with a card groove 8. A cleaning ring plate 9 is slidably connected between the first filter barrel 3, the second filter barrel 4 and the third filter barrel 5. The lower surface of the cleaning ring plate 9 is fixedly connected with two clamping blocks 10, and the clamping blocks 10 are adapted to the card groove 8. The upper surfaces of the two cleaning ring plates 9 are fixedly connected with a lifting handle 11. The outer surface of the main body 1 is fixedly connected to the driving motor 12, and the output shaft of the driving motor 12 is provided with a driving assembly. A fixing ring 13 is provided on the upper part of the main body 1, and the outer surface of the fixing ring 13 is fixedly connected to the fixing connecting rod 14. The other end of the fixing connecting rod 14 is fixedly connected to the outer surface of the main body 1. The main body 1 is provided with a cover plate, and the upper surface of the cover plate is provided with a feed port 15, which is connected to the cavity 2, and the outer surface of the main body 1 is provided with a discharge port 16. When the internal impurities need to be cleaned after the filtering work is completed, the lifting handle 11 is pulled, and the movement of the lifting handle 11 drives the movement of the cleaning ring plate 9, thereby cleaning the impurities between the gaps of the first filter barrel 3, the second filter barrel 4 and the third filter barrel 5, and also scraping the impurities on the surface of the second filter barrel 4 and the third filter barrel 5, finally achieving the preliminary cleaning and collection of filtered impurities. The above-mentioned device solves the problem that some existing multi-stage filtering devices for ink production are not convenient for cleaning and collecting filtered impurities. After the filtration is completed, the device can pull out the impurities by pulling the lifting handle 11, thereby improving the subsequent filtration efficiency, avoiding the blockage of the filter barrel with smaller pore size, greatly improving the filtration effect, and greatly reducing the difficulty of subsequent cleaning through preliminary cleaning. It is simple to operate and has high practicality.

[0026] Furthermore, the driving assembly includes a gear 17, which is fixedly connected to the output shaft of the driving motor 12. A gear ring 18 is rotatably connected between the main body 1 and the fixed ring 13, and the gear ring 18 is meshed with the gear 17. The inner side of the gear ring 18 is fixedly connected to two fixing plates 19, and the upper surfaces of the two fixing plates 19 are provided with mounting grooves 20. The outer surface of the third filter barrel 5 is fixedly connected to two mounting blocks 21, and the mounting blocks 21 are adapted to the mounting grooves 20. The driving motor 12 is started by the staff, and the rotation of the output shaft of the driving motor 12 drives the rotation of the gear ring 18. At this time, the fixing ring 13 will not rotate synchronously under the restriction of the fixed connecting rod 14 The rotation of the gear ring 18 drives the rotation of the fixed plate 19. At this time, the mounting block 21 located inside the mounting groove 20 will rotate synchronously. The rotation of the mounting block 21 drives the rotation of the third filter barrel 5. The rotation of the third filter barrel 5 drives the rotation of the bottom plate 6. The rotation of the bottom plate 6 drives the first filter barrel 3 and the second filter barrel 4 to rotate synchronously. Finally, the impurities in the ink will perform centrifugal motion and stick to the inner wall of the filter barrel. The above device realizes multi-stage filtration of the ink, so that the ink and the impurities in the ink pass through the three filter barrels in turn, thereby accelerating the filtration process. Through step-by-step filtration, the filtration effect is higher and the filtration efficiency is higher.

[0027] When the filtering work is completed, the staff will lift the cover, and the cover will no longer restrict the three filter barrels. Subsequent staff can take out the three filter barrels for subsequent cleaning and replacement.

[0028] Working principle:

[0029] When the multi-stage filtration device for ink production is in use, a worker starts the drive motor 12. The rotation of the output shaft of the drive motor 12 drives the rotation of the gear ring 18. At this time, the fixed ring 13 does not rotate synchronously due to the restriction of the fixed connecting rod 14. The rotation of the gear ring 18 drives the rotation of the fixed plate 19. At this time, the mounting block 21 located inside the mounting groove 20 rotates synchronously. The rotation of the mounting block 21 drives the rotation of the third filter barrel 5. The rotation of the third filter barrel 5 drives the rotation of the bottom plate 6. The rotation of the bottom plate 6 drives the synchronous rotation of the first filter barrel 3 and the second filter barrel 4. Finally, impurities in the ink will undergo centrifugal motion and adhere to the inner wall of the filter barrel. When the filtration work is completed and the internal impurities need to be cleaned, the lifting handle 11 is pulled. The movement of the lifting handle 11 drives the movement of the cleaning ring plate 9, thereby cleaning the impurities between the gaps between the first filter barrel 3, the second filter barrel 4 and the third filter barrel 5. At the same time, impurities on the surface of the second filter barrel 4 and the third filter barrel 5 are also scraped off, ultimately achieving preliminary cleaning and collection of filtered impurities.
