Description

Technical Field

[0001] This utility model relates to the field of pigment dispersion technology, and more specifically, to a high-efficiency filtration device for pigment dispersions used in IJ-INK printing. Background Technology

[0002] Pigment dispersions refer to uniformly distributed suspension systems of pigments formed in liquid media through dispersion technology. As a solid substance that is insoluble in solvents, pigments are usually required to exist in a dispersed state in many applications, such as coatings, inks, plastics, and cosmetics, in order to ensure that they can be uniformly coated, colored, or produce ideal physical properties. Filtration devices are required during the processing of pigment dispersions.

[0003] Existing pigment dispersion filtration devices typically use filter cartridges for filtration. Over time, these cartridges may become damaged and require disassembly and replacement. Traditional filter devices usually connect the top cover and outer shell with bolts. Bolted connections require tools for disassembly and installation, and often involve multiple steps to loosen and tighten the bolts. This process is particularly cumbersome and time-consuming when the filter device is operating in a complex or confined space, making installation and disassembly inconvenient and hindering the removal and replacement of the filter cartridge inside the outer shell.

[0004] Therefore, we have made improvements to this and proposed a high-efficiency filtration device for pigment dispersions in IJ-INK printing. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing pigment dispersion filtration devices typically use filter cartridges for filtration. Over time, these cartridges may become damaged and require disassembly and replacement. Traditional filter devices usually connect the top cover and outer shell with bolts, which require tools for disassembly and installation. This often involves multiple steps to loosen and tighten the bolts, making the process even more cumbersome and time-consuming, especially in complex working environments or confined spaces. This makes installation and disassembly inconvenient and hinders the easy replacement of the filter cartridge inside the outer shell.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] IJ-INK printing pigment dispersion high-efficiency filtration device to improve the above problems.

[0008] The application is as follows:

The top of the water inlet pipe is connected to a diversion pipe, the bottom of the diversion pipe is connected to multiple connecting pipes, the bottom of the connecting pipe is connected to a spray pipe, and one side of the spray pipe is connected to a nozzle.

[0015] In a preferred embodiment of the high-efficiency filtration device for pigment dispersions for printing provided by this utility model, the surface of the diversion pipe is fixedly connected to the inner cavity of the outer shell, and the side of the spray pipe near the outer shell is fixedly connected to the outer shell.

[0016] In a preferred embodiment of the high-efficiency filtration device for pigment dispersions for printing provided by this utility model, an electromagnetic valve is provided on the surface of the drain pipe, and multiple support legs are fixedly installed on the surface of the base.

[0034] Example 1

[0035] Please refer to Figure 1-5 A high-efficiency filtration device for pigment dispersions used in IJ-INK printing includes a base 1, a housing 2 fixedly mounted on the top of the base 1, a connecting sleeve 3 fixedly mounted on the top surface of the housing 2, mounting components 4 fixedly mounted on both sides of the connecting sleeve 3, a top cover 5 movably connected to the top of the housing 2, two limiting plates 6 fixedly mounted on both sides of the bottom of the top cover 5, multiple grooves 7 opened on the opposite side of the two limiting plates 6, a feed pipe 8 connected to the top of the front side of the housing 2, a filter element 9 disposed in the inner cavity of the housing 2, a discharge pipe 10 connected to the bottom of the filter element 9, a cleaning component 11 disposed in the inner cavity of the housing 2, a drain pipe 12 connected to one side of the bottom of the housing 2, and the bottoms of the discharge pipe 10 and the drain pipe 12 both extending to the bottom of the base 1. Mounting assembly 4 includes a protective shell 401. Two protective shells 401 are fixedly mounted on both sides of the connecting sleeve 3. A support plate 402 is provided in the inner cavity of the protective shell 401. Two first movable rods 403 are fixedly mounted on one side of the support plate 402. A fixing frame 404 is movably connected to the surface of the first movable rods 403. A second movable rod 405 is movably connected to one side of the inner cavity of the fixing frame 404. A connecting block 406 is fixedly mounted on one side of the second movable rod 405. A baffle 407 is fixedly mounted on the top of the connecting block 406. Multiple insert rods 408 are fixedly mounted on opposite sides of the two baffles 407. Three springs 409 are fixedly mounted between the opposite sides of the two baffles 407. A pull plate 410 is fixedly mounted on the bottom of the support plate 402. The bottom of the pull plate 410 extends through to the bottom of the protective shell 401. Sliding blocks 411 are fixedly installed on both the front and rear sides of the support plate 402. A sliding rod 412 is slidably connected to the inner cavity of the sliding block 411, and the side of the sliding rod 412 closest to the protective shell 401 is fixedly connected to the protective shell 401. Two sliding plates 413 are fixedly installed in the inner cavity of the protective shell 401, and the surface of the sliding plate 413 is slidably connected to the inner cavity of the baffle 407. A solenoid valve 13 is provided on the surface of the drain pipe 12, and multiple support legs 14 are fixedly installed on the surface of the base 1.

[0036] During implementation, the pigment dispersion enters the interior of the outer shell 2 through the feed pipe 8. Impurities and large particles in the pigment dispersion are removed by the filter element 9. The pigment dispersion then enters the discharge pipe 10 through the filter element 9 and is discharged through the discharge pipe 10. Over time, the filter element 9 may become damaged and needs to be disassembled and replaced. Pulling the pull plate 410 moves the support plate 402. When the support plate 402 moves, it drives the two connecting blocks 406 to move relative to each other through the cooperation of the first movable rod 403, the fixed frame 404, and the second movable rod 405. The movement of the connecting blocks 406 moves the baffle 407, which in turn moves the insertion rod 4. When the baffle 407 moves, it also compresses the spring 409, moving multiple insert rods 408 out of the groove 7 on the limiting plate 6, thereby disassembling the limiting plate 6. The top cover 5 will also be disassembled along with the limiting plate 6. When the top cover 5 needs to be installed, the operation is reversed. This allows the top cover 5 to be quickly installed and removed from the top of the outer shell 2. It is more convenient to disassemble and replace the filter element 9 when it is damaged. Moreover, it is not connected by bolts. Traditional bolt connections require the removal of bolts, which involves many steps and is time-consuming. The filter device with the top quick installation and removal design can directly remove the top cover 5 from the top without the use of tools, which greatly saves the time required to replace the filter element 9.

[0037] Example 2

[0038] The cleaning component 11 includes a water inlet pipe 1101, which is movably connected to the front side of the inner cavity of the housing 2. The top of the water inlet pipe 1101 is connected to a branch pipe 1102, and the bottom of the branch pipe 1102 is connected to multiple connecting pipes 1103. The bottom of the connecting pipes 1103 is connected to a spray pipe 1104, and one side of the spray pipe 1104 is connected to a nozzle 1105. The surface of the branch pipe 1102 is fixedly connected to the inner cavity of the housing 2, and the side of the spray pipe 1104 near the housing 2 is fixedly connected to the housing 2.

[0039] During implementation, a large amount of dirt will be generated on the surface of filter element 9 after long-term use. By connecting the water inlet pipe 1101 to an external water source, the water flows into the interior of the diversion pipe 1102 through the water inlet pipe 1101. The water flow inside the diversion pipe 1102 is diverted to the interior of multiple connecting pipes 1103. The water flow inside the connecting pipes 1103 is then transported to the interior of the spray pipe 1104. The water flow inside the spray pipe 1104 is then sprayed onto the surface of filter element 9 through the nozzle 1105, thereby cleaning the dirt on the surface of filter element 9. By opening the solenoid valve 13, the sewage is discharged through the drain pipe 12.

[0040] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
