Description

Technical Field

[0001] This utility model relates to the field of ink purification technology, specifically to a filtration and purification device for ink production. Background Technology

[0002] Ink is a liquid containing pigments or dyes, used for writing, drawing, printing, etc. It is typically composed of solvents, colorants, additives, and other components. There are many types of ink, which can be categorized according to their uses, such as fountain pen ink, inkjet printer ink, and general printing ink. Different types of ink differ in composition and performance to suit their respective application scenarios and needs. After ink production, it needs to be filtered and purified to remove harmful substances. To improve ink quality, filtration and purification equipment used in ink production is employed.

[0003] For example, prior art application number CN202420080207.3 discloses a purification device for digital printing ink production, including a purification tank and a support column. The support column is fixedly connected to the four lower corners of the purification tank. A tank cover is fixedly connected to the upper end of the purification tank. A feed pipe is fixedly connected to the upper right side of the tank cover. A cap is connected to the outer side of the upper end of the feed pipe. A discharge pipe is fixedly connected to the middle of the bottom of the inner part of the purification tank. A valve is installed inside the discharge pipe. A purification mechanism is connected to both the inner and outer ends of the purification tank. The purification mechanism includes a purification unit and a stirring unit. The purification unit is located at the upper end of the tank cover, and the stirring unit is located inside the purification tank.

[0004] The aforementioned prior art, through practical use, has shown that it mainly removes harmful substances from ink through HEPA and activated carbon filters. However, because the ink contains some tiny ferromagnetic particles, these particles float and clog the HEPA and activated carbon filters after the ink is stirred, which can affect the quality of the ink over time. Therefore, we have improved the aforementioned prior art based on actual usage. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A filtration and purification device for ink production includes a tank. An inlet pipe and a rectangular purification pipe are provided at the upper end of the tank. A stirring rod is rotatably mounted inside the tank. A HEPA filter and an activated carbon filter are installed inside the rectangular purification pipe.

[0012] Furthermore, a sealing gasket is fixed to the inside of the U-shaped box with adhesive, and one side of the sealing gasket is pressed against the right side of the HEPA filter.

[0013] Furthermore, the magnetic block is provided with a groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Harmful gases are filtered through HEPA and activated carbon filters to purify the ink. When harmful gases pass through the HEPA filter, they first pass around the magnetic block. The magnetic properties of the magnetic block can adsorb and collect tiny ferromagnetic particles in the harmful gases in the U-shaped box. This can prevent the tiny ferromagnetic particles from clogging the HEPA and activated carbon filters over a long period of time, thus improving the quality and efficiency of ink filtration and purification.

[0016] 2. The adsorption and collection of tiny ferromagnetic particles within the U-shaped box prevents them from falling out again. Simultaneously, the grooves in the grooves further enhance the adhesion between the tiny ferromagnetic particles and the magnetic block after they are adsorbed by the magnetic block.

[0031] Please see Figures 1 to 6 This utility model provides a technical solution: a filtration and purification device for ink production, including a tank 1, with an inlet pipe 3 and a rectangular purification pipe 4 at the upper end of the tank 1. A stirring rod 13 is rotatably arranged inside the tank 1. A HEPA filter 5 and an activated carbon filter 6 are arranged inside the rectangular purification pipe 4. At least three sets of slag suction components 7 are arranged on one side of the HEPA filter 5. The slag suction component 7 includes a U-shaped box 71 and a magnetic block 72. A through hole 73 is provided on one side of the U-shaped box 71 to increase the airflow pressure and enhance the negative pressure around the U-shaped box 71 to adsorb small ferromagnetic particle impurities. The U-shaped box 71 is located on the air inlet side of the HEPA filter 5, and a magnetic block 72 is arranged on the inner wall of the U-shaped box 71.

[0032] refer to Figure 1 and Figure 3 A motor 12 and a discharge pipe 2 equipped with a solenoid valve are fixed to the lower end of the tank body 1. A connecting shaft is provided at one end of the motor 12, and this shaft passes through the tank body 1 and is fixed to a stirring rod 13 to drive the stirring rod 13 to rotate. A scraper 10 is bolted to one side of the stirring rod 13, and one side of the scraper 10 is pressed against the inner wall of the tank body 1. A liquid level sensor 11 is fixed inside the tank body 1, and a warning light 9 is fixed to the upper end of the tank body 1.

If the ink level is too high or too low, the warning light 9 will sound an alarm to improve equipment safety. The ink level range is 50-110 cm.

[0033] refer to Figure 2A fan 8 is fixed inside the rectangular purification tube 4 by bolts. The fan 8 is located to the left of the activated carbon filter 6. A slide rail is provided inside the rectangular purification tube 4 for sliding installation of the activated carbon filter 6 and the HEPA filter 5. One side of the slide rail is fixed to the inside of the U-shaped box 71 by bolts. At the same time, a removable cover plate is provided at the upper end of the rectangular part of the rectangular purification tube 4 by threads. The top wall of the cover plate abuts against the upper end of the activated carbon filter 6 and the HEPA filter 5, which facilitates the installation and replacement of the activated carbon filter 6 and the HEPA filter 5.

[0034] refer to Figure 2 and Figure 5 A sealing gasket 75 is fixed to the inside of the U-shaped box 71 with adhesive. One side of the sealing gasket 75 is pressed against the right side of the HEPA filter 5 to increase the sealing between the U-shaped box 71 and the HEPA filter 5 and prevent tiny ferromagnetic particles from falling out.

[0035] refer to Figure 6 The magnetic block 72 has a groove 74 inside, which can block tiny ferromagnetic particles and impurities.

[0036] Working principle: Ink is injected into the tank 1 through the feed pipe 3. Then, the electric motor is started to make the stirring rod 13 drive the scraper 10 to rotate, stirring the ink. At the same time, the blower 8 is started to accelerate the floating harmful gas into the rectangular purification tube 4. The harmful gas is filtered through the HEPA filter 5 and the activated carbon filter 6 to achieve ink filtration and purification. When the harmful gas passes through the HEPA filter 5, it will first pass around the magnetic block 72. The magnetism of the magnetic block 72 can adsorb the tiny ferromagnetic particles in the harmful gas and collect them in the U-shaped box 71. This can prevent the tiny ferromagnetic particles from clogging the HEPA filter 5 and the activated carbon filter 6 for a long time, thus improving the quality and efficiency of ink filtration and purification.

[0037] The tiny ferromagnetic particles are adsorbed and collected in the U-shaped box 71 to prevent them from falling out again. At the same time, after the tiny ferromagnetic particles are adsorbed by the magnetic block 72, the groove 74 can block them, which can improve the adsorption between the tiny ferromagnetic particles and the magnetic block 72.
