Description

Technical Field

[0001] This utility model relates to a pigment filtration device, and more particularly to a pigment processing and filtration device applied in the field of filtration equipment. Background Technology

[0002] Pigment paste processing and filtration equipment is a specialized device used in industries such as coatings, inks, and textile printing and dyeing to filter pigment paste raw materials. Its core function is to use the filter structure inside the equipment to trap impurities in the pigment paste (such as pigment clumps, mechanical debris, colloidal particles, etc.) to improve the purity, uniformity, and stability of the pigment paste and meet the quality requirements of different production scenarios.

[0003] Chinese patent CN205886384U discloses a step-by-step color paste filtration device, including a first filter cartridge and a second filter cartridge. A filter bag is suspended from the opening of the first filter cartridge, filling two-thirds of the cartridge's internal volume. A discharge port is located at the bottom of the first filter cartridge, connected via a pipe to the inlet of the second filter cartridge. A double-layered filter cloth is laid below the inlet. This invention achieves high purity color paste through layer-by-layer fine filtration using the first and second filter cartridges, effectively removing zirconium bead fragments, resin particles, and impurities generated during the dispersion milling process.

[0004] After the filter cloth traps the pigment, the residual pigment is only recovered by natural gravity or simple manual squeezing. However, the pigment itself often has a high viscosity, especially for products used in inks, coatings and other fields. Its viscous properties make it easy to penetrate deep into the pores of the filter cloth fibers. Simple treatment methods cannot effectively break the adhesion between the pigment and the filter cloth, resulting in a large amount of pigment remaining in the filter cloth and being difficult to discharge, causing serious waste of raw materials. Utility Model Content

[0005] The technical problem this invention aims to solve is that after the filter cloth traps the pigment paste, the residual paste is not recovered solely by natural gravity or simple manual squeezing. However, pigment pastes often have high viscosity, especially those used in inks, coatings, and other fields. Their viscous nature makes them easily penetrate deep into the pores of the filter cloth fibers. Simple processing methods cannot effectively break the adhesion between the pigment paste and the filter cloth, resulting in a large amount of pigment paste remaining in the filter cloth and being difficult to remove, causing serious waste of raw materials.

[0006] To solve the above problems, this utility model provides a color paste processing and filtration device, including a filter device frame, a stainless steel outer filter cylinder installed at the inner end of the filter device frame, an inner filter cloth cylinder provided at the inner end of the stainless steel outer filter cylinder, a motor fixedly connected to the lower inner wall of the filter device frame, a linkage electromagnetic coil fixedly connected to the output end of the motor, a screwing and squeezing magnetic ring rotatably connected to the lower inner wall of the stainless steel outer filter cylinder, the screwing and squeezing magnetic ring and the linkage electromagnetic coil cooperating with each other, and two metal mating rings fixedly connected to the lower end of the inner filter cloth cylinder, the two metal mating rings being magnetically connected to each other inside and outside the inner filter cloth cylinder, the metal mating rings and the screwing and squeezing magnetic ring cooperating with each other.

[0007] In the above-mentioned color paste processing and filtration equipment, the equipment of this solution uses a double-layer filtration structure of stainless steel outer filter cylinder and inner filter cloth cylinder. With the help of motor-driven linkage electromagnetic coil and rotating squeezing magnetic coil, the inner filter cloth cylinder is rotated and squeezed, which can squeeze out the residual color paste in the cloth cylinder, improve the utilization rate of color paste and reduce raw material waste.

[0008] As a further improvement of this application, the upper end of the inner filter cylinder is fixedly connected with an outwardly protruding cloth ring, and the upper and lower sections of the stainless steel outer filter cylinder are both fixedly connected with mounting thick rings.

[0009] As a further improvement to this application, multiple anti-detachment external textures are provided on the outer side of the mounting thick ring located on the upper side, and a fastening clamp ring is provided at the upper end of the convex cloth ring.

[0010] As a further improvement of this application, the fastening clamp ring and the anti-detachment outer texture are interlocked, and a top cloth strip is fixedly connected to the upper end of the inner side wall of the filter inner cloth cylinder.

[0011] As another improvement of this application, a liquid outlet is fixedly connected to the right end of the filter device frame, and multiple supporting bottom legs are fixedly connected to the lower end of the filter device frame.

[0012] As another improvement of this application, multiple supporting bottom legs are arranged in a ring at equal intervals, and a sealed top cover is installed on the upper end of the filter equipment frame.

[0013] As another improvement of this application, the upper end of the sealed top cover is equipped with multiple tight-fitting parts, and the lower end of the filter equipment frame is fixedly connected to an impurity treatment bottom cylinder.

[0014] In summary, this solution utilizes a double-layer filtration structure consisting of a stainless steel outer filter cylinder and an inner filter cloth cylinder to achieve graded filtration of the color paste. This effectively traps impurities of different particle sizes, ensuring the purity of the filtered color paste. The equipment is equipped with a motor drive system that uses magnetic transmission through a linkage magnetic ring and a rotating squeezing magnetic ring to drive the inner filter cloth cylinder to rotate and squeeze. This fully squeezes out the residual color paste from the fiber pores of the cloth cylinder, avoiding the waste of raw materials caused by the retention of high-viscosity color paste, significantly improving color paste recovery efficiency, and reducing production costs. The fitting design of the fastening clamp ring and the anti-detachment outer texture, combined with the sealing top cover and the tight locking parts, ensures the stable installation of the inner filter cloth cylinder.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-6 A color paste processing filtration device is shown, including a filter device frame 1. A stainless steel outer filter cylinder 4 is installed at the inner end of the filter device frame 1. An inner filter cloth cylinder 6 is provided at the inner end of the stainless steel outer filter cylinder 4. A motor 11 is fixedly connected to the lower inner wall of the filter device frame 1. A linkage electromagnetic coil 12 is fixedly connected to the output end of the motor 11. A screwing and squeezing magnetic coil 13 is rotatably connected to the lower inner wall of the stainless steel outer filter cylinder 4. The screwing and squeezing magnetic coil 13 and the linkage electromagnetic coil 12 cooperate with each other. Two metal mating rings 14 are fixedly connected to the lower end of the inner filter cloth cylinder 6. The two metal mating rings 14 are magnetically connected to each other inside and outside the inner filter cloth cylinder 6. The metal mating rings 14 and the screwing and squeezing magnetic coil 13 cooperate with each other.

[0027] Figures 2-6 The filter inner cloth cylinder 6 is shown to be fixedly connected to the upper end of an outwardly protruding cloth ring 15. The upper and lower sections of the stainless steel filter outer cylinder 4 are both fixedly connected to mounting thick rings 8. The upper end of the inner side wall of the filter inner cloth cylinder 6 is fixedly connected to a top cloth strip 7. The right end of the filter equipment frame 1 is fixedly connected to a liquid outlet 3. The lower end of the filter equipment frame 1 is fixedly connected to multiple supporting bottom legs 2, which are arranged in a ring at equal intervals. The upper end of the filter equipment frame 1 is equipped with a sealing top cover 16, and the upper end of the sealing top cover 16 is equipped with multiple tightly locking parts 17. The lower end of the filter equipment frame 1 is fixedly connected to an impurity treatment bottom cylinder 18.

[0028] Figures 2-6In this design, the filter frame 1 serves as the overall support structure, with multiple ring-shaped, equidistant support legs 2 providing stable support at the bottom. The color slurry enters from the top of the device and is first filtered through the stainless steel outer filter cylinder 4 and its inner filter cloth cylinder 6. The top strip 7 of the inner filter cloth cylinder 6 helps to intercept some impurities. The filtered color slurry is discharged from the outlet 3 at the right end of the filter frame 1. The motor 11 is fixed to the lower inner wall of the filter frame 1. After startup, the linkage electromagnetic coil 12 at its output end rotates accordingly. The rotating squeezing magnetic ring 13, rotatably connected to the lower inner wall of the stainless steel outer filter cylinder 4, cooperates with the linkage electromagnetic ring 12. Through magnetic transmission, the linkage electromagnetic ring 12 drives the rotating squeezing magnetic ring 13 to rotate. Two magnetically connected metal mating rings 14 fixed at the lower end of the inner filter cloth cylinder 6 cooperate with the rotating squeezing magnetic ring 13, causing the rotating squeezing magnetic ring 13 to rotate. During rotation, the metal docking ring 14 is driven, causing the inner filter cloth cylinder 6 to rotate or squeeze. This helps to further squeeze out the color slurry trapped in the inner filter cloth cylinder 6, improving filtration efficiency and promoting the separation of impurities from the color slurry. The sealing top cover 16 is installed on the upper end of the filter equipment frame 1 through multiple tightly locking parts 17 to ensure the internal sealing of the equipment and prevent color slurry leakage. The separated impurities eventually fall into the impurity treatment bottom cylinder 18 at the lower end of the filter equipment frame 1 for subsequent centralized cleaning. The equipment achieves graded filtration of color slurry through the double-layer filtration structure of stainless steel outer filter cylinder 4 and inner filter cloth cylinder 6, effectively trapping impurities of different particle sizes and ensuring the purity of the filtered color slurry. At the same time, the motor 11 drives the linkage electromagnetic ring 12 and the twisting squeezing magnetic ring 13 to rotate and squeeze the inner filter cloth cylinder 6, which can squeeze out the residual color slurry in the cloth cylinder, improve the utilization rate of color slurry, and reduce raw material waste.

[0029] Second implementation method:

[0030] Figure 2 , Figure 7 This invention discloses a color paste processing and filtration device. Multiple anti-detachment external textures 9 are provided on the outer side of the upper mounting thick ring 8. A fastening clamp ring 10 is provided at the upper end of the protruding cloth ring 15. The fastening clamp ring 10 and the anti-detachment external textures 9 are interlocked. The mounting thick rings 8 at both ends of the stainless steel filter outer cylinder 4 have anti-detachment external textures 9 on the upper side that interlock with the fastening clamp ring 10 above the protruding cloth ring 15 at the upper end of the filter inner cloth cylinder 6. This interlocking design of the fastening clamp ring 10 and the anti-detachment external textures 9, combined with the sealing top cover 16 and the tight locking part 17, ensures the stable installation of the filter inner cloth cylinder 6.
