Description

Technical Field

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

[0002] Ink plays a crucial role in the printing industry. It is the substance used to form graphic information during the printing process, and it can directly determine the tone, color, and clarity of the image on the printed material. However, due to factors such as manufacturing equipment and production processes, certain impurities are present in ink during the current ink manufacturing process. The main component of these impurities is iron filings. When iron filings are present in the ink, they will produce marks such as knife lines and trailing marks on the printing paper during the printing process, thus affecting the printing effect.

[0003] Chinese patent application CN105396346B discloses an ink filtering device, comprising: an oil drum, a first filter layer installed on the upper part of the oil drum and an oil outlet provided at the bottom; a second filter layer located inside the oil drum and disposed between the first filter layer and the oil outlet, and a magnet disposed on the second filter layer.

[0004] In the existing technology, multiple filter layers are set in the oil drum. Since the filter layers filter ink, ink is easily left on the filter layers. In addition, the filtered impurities remain in the filter layers, which makes the filter layers very easy to clog. This causes the ink to pass through the filter layers to gradually slow down and the filtration effect to gradually decrease. The cleaning needs to be more frequent, and the filter layers are located inside the oil drum, making cleaning even more difficult. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for ink production, which solves the problems of frequent cleaning requirements and high cleaning difficulty in the existing technology.

[0018] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1-2As shown, a filtration device for ink production includes a barrel 1. The bottom of the barrel 1 has an oil outlet pipe 11 and multiple support legs 12. The top of the barrel 1 is open. A first filter layer 21, separate from the inner wall of the barrel 1, is located in the upper part of the barrel 1. A second filter layer 22, also separate from the inner wall of the barrel 1, is located between the first filter layer 21 and the oil outlet pipe 11. In use, ink enters from the top of the barrel. In the first filter layer, particulate impurities in the ink are blocked and separated, thus separating the particulate impurities. The ink then flows into the second filter layer. A magnetic element (such as a permanent magnet or a substance with magnetic adsorption) is located in the middle of the second filter layer, which can adsorb magnetic substances. Iron filings in the ink are adsorbed by the magnetic element, further enhancing the impurity removal effect on the ink. The top edge of the first filter layer 21 and the top surface of the second filter layer 22 are also connected. The edges gradually slope downwards towards the center, allowing ink to flow on the first and second filter layers, reducing accumulation on the top surfaces of the first and second filter layers and improving filtration efficiency. A hanger 23 connected to the first filter layer 21 is located at the top opening of the barrel 1. The hanger, through the connection of the first filter layer, suspends and fixes the first filter layer inside the barrel, while also securing itself to the top of the barrel, facilitating removal of the first filter layer and simplifying installation. Multiple connecting rods 24, detachably connected to the top edge of the second filter layer 22, are located at the bottom edge of the first filter layer 21. The two ends of the connecting rods are connected to the first and second filter layers respectively, allowing the hanger to suspend and fix the first and second filter layers together. During subsequent cleaning, the first and second filter layers can also be removed together via the hanger, making disassembly and assembly more convenient and improving cleaning efficiency.

[0020] like Figure 2-3 As shown, the bottom of the hanger 23 is provided with a connecting part 231. The connecting part is located at the bottom end of the hanger, increasing the contact area at the bottom end of the hanger, making the connection between the hanger and the first filter layer more stable and reliable. A soft padding layer 232 is provided between the connecting part 231 and the top edge of the first filter layer 21. The connecting part 231 and the first filter layer 21 are connected by bolts. The soft padding layer is made of rubber material, which enhances the reliability and stability of the connection between the hanger and the first filter layer, and facilitates disassembly and cleaning, reducing the difficulty of cleaning. The top of the hanger 23 is provided with a support part 233 that bends outward and matches the opening of the barrel 1. The outside of the support part 233 is provided with a fixing part 234 that bends downward and is threadedly connected to the outer wall of the barrel 1. The hanger forms a U-shaped structure that matches the opening at the top of the barrel through its support part and fixing part, so that the hanger can stably suspend and fix the first filter layer and the second filter layer. The hanger is threadedly connected to the outer wall of the barrel through the fixing part, which can strengthen the connection strength, prevent shaking and affect the filtration effect, and make disassembly and assembly more convenient and easier to clean.

[0021] like Figure 2As shown, an annular support block 13 is provided on the inner wall of the barrel 1 corresponding to the bottom of the second filter layer 22, supporting the edge of the second filter layer 22. The annular support block supports the second filter layer, so that when the hanger is threaded onto the outer wall of the barrel, the first filter layer and the second filter layer can be longitudinally pressed by the limiting of the annular support block, which strengthens the stability of the first filter layer and the second filter layer. The middle part forms a channel for ink to pass through, ensuring normal ink filtration. The annular support block 13 is provided with multiple evenly distributed openings 131. The openings 131 are provided with telescopic springs 132 that abut against the bottom surface of the second filter layer 22. The telescopic springs are located in the openings, which can increase the force on the second filter layer, thereby strengthening the pressing strength of the hanger, improving the stability and reliability of fixing the first filter layer and the second filter layer. When removing the first filter layer and the second filter layer, the action of the telescopic springs on the second filter layer can assist the second filter layer to move upward, making the removal of the first filter layer and the second filter layer more convenient and effortless.

[0022] like Figure 2-4 As shown, the top end of the connecting rod 24 is rotatably connected to the first filter layer 21, and both ends of the connecting rod are connected to the first filter layer and the second filter layer respectively. The connecting rod 24 can be flipped outward. One end of the connecting rod is rotatably connected to the first filter layer. During assembly or disassembly and cleaning, it can be flipped outward to disconnect from the second filter layer. The bottom end of the connecting rod 24 is provided with a bent portion 241 extending inward and detachably connected to the second filter layer 22. The top edge of the second filter layer 22 is provided with a limiting block 25 that cooperates with the side wall of the connecting rod 24. The limiting block 25 is provided with a limiting groove 251 for the bent portion 241 to extend into. The top surface of the limiting groove 251 is flush with the side wall of the connecting rod 24. A gap is left between the bent portions 241. The aforementioned limiting block is fixed at the edge of the top surface of the second filter layer and covers the bent portion. When the bent portion is located in the limiting groove, a gap is left between the top surface of the bent portion and the top surface of the limiting groove. This allows the connecting rod to rotate and move the bent portion away from the limiting groove during disassembly, increasing the movement space of the bent portion. When the first and second filter layers are removed, the top surface of the bent portion located in the limiting groove can contact the top surface of the limiting groove, causing the second filter layer to move upward. This effectively ensures the convenience of disassembly and assembly. At the same time, it can maintain a pressing effect on the second filter layer during assembly, ensuring the stability of the second filter layer.

[0023] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
