Therefore, those skilled in the art have provided an ultra-high paint capacity combined dry paint mist filter to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultra-high paint capacity combined dry paint mist filter. It utilizes 3D-printed fiber material as the primary filter layer. This material not only possesses excellent elasticity and toughness but also exhibits superior paint absorption capacity and air permeability, ensuring the product's lifespan. For the secondary filtration, an increasing density fiber structure filter cotton is used, ensuring the high-efficiency interception performance of the dry filter.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-capacity combined dry paint mist filter includes an outer cardboard frame, a first filter mechanism fixedly installed at the front end inside the outer cardboard frame, and a second filter mechanism fixedly installed at the rear end inside the outer cardboard frame.

[0015] 1. This utility model proposes an ultra-high paint capacity combined dry paint mist filter. The filter element is equipped with multiple layers of filter media. The first-stage filter layer uses 3D printed fiber material, which has excellent elasticity, toughness, paint absorption capacity and air permeability, and can effectively intercept paint mist particles of different sizes, ensuring the product's service life.

[0024] 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.

[0025] Reference Figure 1-5 An embodiment of this utility model is provided: an ultra-high paint capacity combined dry paint mist filter, including an outer carton frame 1, a first filter mechanism 2 fixedly installed at the front end inside the outer carton frame 1, and a second filter mechanism 3 fixedly installed at the rear end inside the outer carton frame 1. The outer carton frame 1 is made of American cardboard, and multiple slots are opened inside the first filter mechanism 2 and the second filter mechanism 3.

[0026] Specifically, the outer carton frame 1 is made of high-strength American cardboard, which has good corrosion resistance and certain moisture-proof properties, ensuring the stability of the filter element during long-term use. The first filter mechanism 2 uses fiber material manufactured by 3D printing technology as the primary filter layer. This material not only has excellent elasticity and toughness, but also exhibits excellent paint absorption capacity and air permeability, ensuring the product's service life. The second filter mechanism 3 uses fiber structure filter cotton 303 with increasing density, ensuring the high-efficiency interception performance of the dry filter. Furthermore, the first filter mechanism 2 and the second filter mechanism 3 are connected by a snap-fit ​​design, making the installation of each component stable and easy to disassemble and maintain. While ensuring the overall structural strength, it can adapt to different working environments.

[0027] Reference Figure 1 , Figure 2 The first filtration mechanism 2 includes two filter plates 201 and four connecting plates 202. Both filter plates 201 have multiple air inlets 203 on their front sides. The two filter plates 201 are snapped and fixed to the connecting plates 202 at the center of their four sides. The filter plates 201 are made of 3D printed fiber material.

[0028] Specifically, in the first filtration mechanism 2, 3D printing technology can precisely control the arrangement of fibers and pore structure, giving the filter plate 201 a unique microstructure, which greatly increases its specific surface area. The elasticity and toughness of this fiber material make it less prone to damage when facing paint mist impact, and it can maintain good filtration performance. Its excellent paint absorption capacity comes from the special chemical properties and microstructure of the fiber surface, which can quickly adsorb paint mist particles and ensure smooth airflow through its own air permeability, effectively intercepting paint mist particles of different sizes, especially having a strong capture ability for tiny particles, thereby ensuring the product's service life.

[0029] Reference Figure 1 , Figure 4 , Figure 5 The second filtration mechanism 3 includes multiple support frames 301, multiple connecting horizontal plates 302, filter cotton 303, and connecting vertical plates 305. Multiple air vents 304 are provided on the upper end of the multiple connecting horizontal plates 302. The filter cotton 303 is snapped and fixed in the middle position of the multiple connecting horizontal plates 302. Multiple connecting vertical plates 305 are snapped and fixed on both sides of the multiple connecting horizontal plates 302. The multiple connecting horizontal plates 302 and the connecting vertical plates 305 are snapped together to form a grid. A U-shaped groove is provided on one side of the multiple connecting horizontal plates 302. The multiple support frames 301 are movably arranged inside the U-shaped groove. The filter cotton 303 is made of blue and white progressive fiber cotton.

[0030] Specifically, in the second filtration mechanism 3, the structure of the blue-white incremental fiber cotton is carefully designed according to the filtration requirements of paint mist particles. Its fiber density gradually increases from the air inlet to the air outlet, which can more finely intercept the paint mist after passing through the first filtration mechanism 2. When the paint mist airflow passes through, the looser fiber layer initially filters larger particles. As the airflow goes deeper, the gradually denser fiber layer can capture smaller paint mist particles, ensuring the high-efficiency interception performance of the dry filter. The support frame 301 provides stable support for the connecting horizontal plate 302, preventing deformation or displacement when high-flow paint mist impacts or equipment vibrations, ensuring that the filter cotton 303 is always in the best working condition. The vent holes 304 on the connecting horizontal plate 302 help to evenly distribute the airflow, avoid local airflow being too fast or too slow, and improve the consistency of the filtration effect.

[0031] Working Principle: During operation, the airflow containing paint mist first enters from the air inlet of the outer carton frame 1, passes through the air inlet 203 of the first filtration mechanism 2, and enters between the filter plates 201. Because the filter plates 201 are made of 3D printed fiber material, their special structure and performance can quickly adsorb and intercept larger paint mist particles while allowing the airflow to pass relatively smoothly, reducing airflow resistance. The airflow after preliminary filtration continues to flow backward into the second filtration mechanism 3. In the second filtration mechanism 3, the airflow is first evenly dispersed onto the filter cotton 303 through the vent holes 304 on the connecting horizontal plate 302. The blue-white progressive fiber structure of the filter cotton 303 intercepts paint mist particles sequentially according to their size, further removing tiny paint mist particles. The clean airflow after two stages of filtration is discharged from the air outlet of the outer carton frame 1, thus achieving efficient filtration of paint mist and meeting the environmental protection requirements in industrial production. Furthermore, due to the structural design and material selection of this invention, the filter element has a large paint capacity and a long service life, reducing the increased costs and production interruptions caused by frequent filter element replacements.

[0032] 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.
