Description

Technical Field

[0001] This utility model relates to the field of colorant processing technology, and in particular to a mixing and filtration device for the production of compound colorants. Background Technology

[0002] Compound colorants are products made by mixing two or more different types of colorants, such as pigments or dyes, in a certain proportion to achieve specific color effects, performance improvements, or cost optimization. Currently, in the production process of compound colorants, most commonly used mixing devices rely on internal agitators for stirring and mixing, lacking filtration mechanisms. This can introduce tiny impurity particles from the raw materials or during the mixing process. If these impurities are not removed, they will directly affect the quality and appearance of the final product, such as causing spots, streaks, or other unevenness. Even if the raw materials themselves are fine powders or liquids, the shear forces and collisions during the mixing process may cause some particles to aggregate or break, forming larger agglomerates. Without a filtration mechanism, it is impossible to guarantee that all components reach an ideal fineness standard, affecting color consistency and application performance.

[0003] For example, Chinese utility model patent CN216825763U discloses a mixing device for producing carbon black colorant. The device allows operators to open the electric push rods at both ends of filter screen B, causing it to swing left and right. A large amount of carbon black powder falls onto the surface of the swinging filter screen B, allowing it to pass evenly through the filter screen B into the feed inlet B, which then guides it into the outer casing. Impurities in the carbon black powder remain on the filter screen surface. Opening the valve allows a large amount of carbon black colorant to exit through the discharge outlet into the outer casing. As this large amount of carbon black colorant passes through filter screen A at the bottom of the waste bin, waste residue from the carbon black colorant remains on the surface of filter screen A, and the carbon black colorant falls into the storage bin through the discharge outlet. While this solution solves the filtration problem, replacing and cleaning filter screens A and B requires machine downtime, affecting work efficiency. Summary of the Invention

[0004] The present invention aims to address the shortcomings of the prior art by providing a mixing and filtration device for the production of compound colorants.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a mixing and filtering device for producing compound colorants, comprising a mixing cylinder, a support for the mixing cylinder, rectangular material cylinders on both sides at the top and bottom, a feed pipe connected to the mixing cylinder at the bottom of the upper material cylinder, and a discharge pipe at the bottom of the lower material cylinder, a filter assembly inside the material cylinder, a hollow disc rotatably connected to the top of the mixing cylinder, a power mechanism for driving the disc to rotate on the mixing cylinder, a first rotating shaft rotatably connected to the center of the disc, a first gear on the first rotating shaft, and several second rotating shafts rotatably connected to the disc evenly distributed around its circumference, each second rotating shaft having a second gear meshing with the first gear. The rotating shaft and the second rotating shaft pass through the mixing cylinder and are equipped with stirring blades. The first gear and the second gear are located inside the disc. The top of the disc is equipped with a first motor that drives the first rotating shaft to rotate. The filter assembly includes a first filter screen frame and a second filter screen frame. The two adjacent sides of the material cylinder are respectively provided with openings corresponding to the first filter screen frame and the second filter screen frame. The first filter screen frame and the second filter screen frame are alternately inserted into the material cylinder by passing through the corresponding openings. The first filter screen frame and the second filter screen frame are provided with a baffle on the side away from the material cylinder. The baffle is provided with a handle on the outside. The outside of the material cylinder is provided with a U-shaped groove corresponding to the first filter screen frame and the second filter screen frame on the baffle.

[0017] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-4As shown, a mixing and filtering device for producing compound colorants includes a mixing cylinder 1 and a support 2 for supporting the mixing cylinder 1. Rectangular material cylinders 3 are provided at the top and bottom of both sides of the mixing cylinder 1. The bottom of the upper material cylinder 3 is provided with a feed pipe 4 connected to the mixing cylinder 1, and the bottom of the lower material cylinder 3 is provided with a discharge pipe 5. A filtering assembly is provided inside the material cylinder 3, including a first filter frame 16 and a second filter frame 17. Two adjacent sides of the material cylinder 3 are respectively provided with openings corresponding to the first filter frame 16 and the second filter frame 17. The first filter frame 16 and the second filter frame 17 are alternately inserted into the material cylinder 3 through the corresponding openings. The filter frame 16 and the second filter frame 17 have insert blocks 18 on the side facing the material cylinder 3. The material cylinder 3 has slots corresponding to the insert blocks 18, and the insert blocks 18 are inserted into the slots. The first filter frame 16 and the second filter frame 17 have baffles 19 on the side facing away from the material cylinder 3. The baffles 19 have handles 20 on their outer sides. The outer side of the material cylinder 3 has U-shaped grooves 21 corresponding to the baffles 19 and the first filter frame 16 and the second filter frame 17. The baffles 19 are slidably disposed in the U-shaped grooves 21. The upper part of the inner wall of the material cylinder 3 has a guide ring plate 22. The bottom of the baffles 19 has several sliders. The bottom of the U-shaped grooves 21 has sliding grooves 23 corresponding to the sliders, and the sliders are slidably disposed in the sliding grooves 23. At the same time, to avoid clogging, a vibrator can be installed on the outer side of the material cylinder 3. The edges of the first filter frame 16 and the second filter frame 17 match the openings. When the first filter frame 16 is inserted into the material cylinder 3, its baffle 19 blocks the opening. The insert block 18 on the second filter frame 17 is inserted into the corresponding opening to block it. The bottom of the guide ring plate 22 is set to retract inward to ensure that the material falls on the filter screen.

[0020] In use, the material enters through the upper material cylinder 3 and then enters the mixing cylinder 1 through the feed pipe 4. Before entering the mixing cylinder 1, it passes through the upper first filter screen 16 to filter impurities. When the material is mixed, the first filter screen 16 is pulled out and the second filter screen 17 is inserted into the material cylinder 3 to clean the first filter screen 16. After mixing, the material is filtered through the lower filter assembly and then discharged through the discharge pipe 5.

[0021] A hollow disc 6 is rotatably connected to the top of a mixing cylinder 1. A power mechanism drives the disc 6 to rotate on the mixing cylinder 1. A first rotating shaft 7 is rotatably connected to the center of the disc 6, and a first gear 8 is mounted on the first rotating shaft 7. Several second rotating shafts 9 are evenly distributed around the circumference of the disc 6, and each second rotating shaft 9 has a second gear 10 that meshes with the first gear 8. The first and second rotating shafts 7 and 9 pass inside the mixing cylinder 1 and are equipped with stirring blade assemblies. The first gear 8 and second gear 10 are located inside the disc 6. A first motor 11, which drives the first rotating shaft 7, is located at the top of the disc 6. The power mechanism includes a third gear 12 located on the outside of the disc 6, and a second motor, which drives the third gear 12, is located on the outside of the mixing cylinder 1. Scrapers 13, which contact the inner wall of the mixing cylinder 1, are connected to the top and bottom of the first rotating shaft 9. The stirring blade assembly includes spiral blades 14 mounted on the first rotating shaft 7 and several pairs of stirring rods 15 arranged from top to bottom on the second rotating shafts 9.

[0022] In use, the first motor 11 and the second motor operate, and the disc 6 drives the first rotating shaft 7 and the second rotating shaft 9 to rotate. At the same time, the second rotating shaft 9 rotates on its own axis. The spiral blades 14 not only help to lift the material from the bottom to the top, but also generate flow in the vertical direction, ensuring that the material is evenly distributed in the mixing drum 1. The second rotating shaft 9 is equipped with stirring rods 15, which can shear and disperse the material in the horizontal direction, further enhancing the mixing effect. Through the synergistic effect of the central spiral blades 14 and the surrounding stirring rods 15, the material can be effectively prevented from stratifying or settling during the mixing process. Especially for compound colorant components with large density differences, it can accelerate the contact and exchange between materials, greatly shortening the time required to reach a uniform state. The scraper 13 scrapes off the material adhering to the inner wall of the mixing drum 1 to avoid affecting the mixing effect.

[0023] The first filter frame 16 and the second filter frame 17 of this utility model can be used alternately without stopping the machine for replacement and cleaning. They are convenient to use and do not affect work efficiency. Moreover, they achieve multi-dimensional and high-intensity material mixing with good mixing effect and high efficiency.
