Description

Technical Field

[0001] This utility model relates to the field of chemical synthesis, and in particular to a filtration device. Background Technology

[0002] High-viscosity fluids, such as pigments and inks, have strong intermolecular forces, making their flowability far lower than that of ordinary fluids. When passing through high-precision filters, the fluid must overcome greater resistance to pass through these tiny pores due to the extremely small pore size (existing high-viscosity fluid filters have pore sizes of 1800 mesh or larger). The intertwining of pigment particles and binders in pigments increases overall viscosity, making it difficult to flow within the narrow pores of the filter, thus significantly reducing filtration speed. For materials requiring even higher precision filtration, the filtration efficiency is even lower.

[0003] When filtering high-viscosity fluids, the viscosity of the fluid and the resistance of the filter screen result in an uneven pressure distribution on the screen surface. The fluid pressure is relatively high near the center of the filter screen, while the pressure is lower at the edges. This pressure unevenness causes inconsistent fluid flow velocity across the filter screen surface, which is detrimental to improving overall filtration efficiency. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 The present invention provides an embodiment of a filtration device, comprising: a barrel 1; a first filtration structure 2 and a second filtration structure 3 are respectively provided on the two end faces of the barrel 1, so that the material enters the inside of the barrel 1 through the first filtration structure 2 and then exits through the second filtration structure 3 to filter the material.

[0025] In this embodiment, by designing a first filter structure 2 and a second filter structure 3, the material passes through two stages of filtration in sequence. The first filter structure 2 first performs preliminary filtration on the material, intercepting larger particulate impurities; the second filter structure 3 then performs fine filtration, further removing tiny particles, thereby improving the accuracy and effectiveness of filtration and ensuring that the output material has a lower impurity content. The two-stage filtration shares the filtration load, which, compared to the existing single filter screen, can reduce the frequency of filter screen clogging, extend the service life of the entire filtration device, and improve filtration efficiency.

[0026] The first filter structure 2 includes a first connecting part 21, which is annular and has threads on its inner side. The first connecting part 21 is connected to the barrel 1 by threads. A first filter screen 22 is provided on the first connecting part 21, which is circular.

[0027] In this embodiment, the first connecting part 21 is connected to the barrel 1 by a thread. This connection method facilitates the installation and removal of the first filter screen 22, reducing maintenance difficulty and cost. The threaded connection ensures a tight connection, prevents material leakage during filtration, ensures the stability and reliability of the filtration process, and maintains a good filtration effect.

[0028] The first filter screen 22 is circular and can effectively cover the area where the material enters during the initial filtration stage, ensuring filtration of a large area. The material of the first filter screen 22 is stainless steel, and the filtration pore size of the first filter screen 22 is 800-1000 mesh. In this embodiment, 900 mesh is preferred.

[0029] The second filter structure 3 includes a second connecting part 31, which is annular and has threads on its inner side. The second connecting part 31 is connected to the barrel 1 by the threads. A second filter screen 32 is provided on the second filter structure 3, which is conical.

[0030] In this embodiment, the second connecting part 31 has the same structure as the first connecting part 21 and is installed on the other side of the barrel 1. The second filter screen 32 is conical, which increases the surface area of ​​the filter screen and makes the contact area between the material and the filter screen larger when the material passes through, which helps to improve the filtration efficiency. The material of the second filter screen 32 is stainless steel. The second filter screen 32 has a pore size greater than 2800 mesh, which is different from the pore size design of the first filter screen 22. With the dual filtration structure, it can realize the graded filtration of impurities of different particle sizes, improve the overall filtration accuracy, and adapt to the filtration needs of different materials.

[0031] A shell 4 is provided on the outer side of the barrel body 1, and a receiving cavity is formed between the shell 4 and the barrel body 1. A heating element 5 is provided on the inner side of the receiving cavity. The heating elements 5 are evenly distributed in a ring in the receiving cavity, so that the barrel body 1 heats the material inside.

[0032] In this embodiment, a receiving cavity is formed between the shell 4 and the barrel 1. This cavity not only provides installation space for the heating element 5 but also provides some protection. It prevents the heating element 5 from being directly exposed, avoiding accidental contact and injury to operators. The heating elements 5 are evenly distributed around the receiving cavity, ensuring uniform heating of all parts of the barrel 1. The heating range is 0-80℃. During the filtration process, uneven heating in certain areas may lead to inconsistent viscosity changes in some materials, affecting the stability of the filtration effect. Uniform heating ensures that all materials within the barrel 1 are effectively heated, resulting in similar viscosity reductions, thus guaranteeing the stability of the filtration process and improving filtration quality. The material is heated within the barrel 1, reducing its viscosity, allowing it to flow more smoothly from the second filter screen 32, thereby increasing the filtration speed.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
