Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a porous composite filter suitable for high-precision filtration. Background Technology

[0002] A filter (also known as an oil filter, filter, or filtration device) is a device that removes impurities, particles, and other contaminants from liquids and gases using physical and chemical methods. Filters are widely used in various fields, such as industry, chemicals, pharmaceuticals, food processing, and environmental protection, for purifying, separating, and concentrating substances. A porous composite filter is a filtration device that utilizes porous materials and composite structures for solid-liquid separation. It is widely used in industry, chemicals, food, and environmental protection to remove impurities, solid particles, and contaminants from liquids. It typically involves staged filtration using multiple filter media with different properties, resulting in highly efficient and stable filtration performance.

[0003] Liquid filtration equipment typically uses a single filtration method and a single filter mesh size to remove solid particles and impurities from liquids. Its design usually includes a filter housing, inlet and outlet pipes, filter media (such as filter screens, filter cartridges, activated carbon, etc.), and a support structure. During operation, liquid enters the filter through the inlet and flows within the filter media. Larger particles are trapped on the surface of the media, while smaller particles are removed through the pores of the filter media. The clean liquid is then discharged from the outlet. This design is simple and easy to operate, but it is generally suitable for filtering liquids with relatively large and homogeneous particles.

[0004] In existing technologies, many filtration devices employ a single filtration method, such as physical filtration or chemical filtration, which often fails to meet the demands of high-precision filtration. This results in limitations in filtration accuracy, efficiency, and adaptability. Furthermore, the use of fixed filter mesh sizes prevents adjustment based on different filtration requirements, leading to issues such as insufficient filtration accuracy, high energy consumption, and frequent maintenance during actual operation. Therefore, a multi-porous composite filter suitable for high-precision filtration is proposed to address these problems. Utility Model Content

Through multiple filtration measures, the accuracy of liquid filtration is improved.

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a porous composite filter suitable for high-precision filtration, comprising a cylindrical filter chamber 1. The cylindrical filter chamber 1 is a standard cylindrical shape with a smooth and regular appearance and smooth inner and outer walls. It can withstand various pressures generated during the filtration process and external impacts, ensuring the stability of the entire filter structure and exhibiting excellent corrosion resistance. Filter paper 2 is fixedly connected inside the cylindrical filter chamber 1. Filter paper 2 has a thin, ring-shaped structure and is made of fiber materials with good filtration performance, such as glass fiber filter paper, which can effectively intercept tiny particulate impurities. Activated carbon filter plate 3 is fixedly connected inside the filter paper 2. Activated carbon filter plate 3 has a ring-shaped structure and is made of activated carbon particles with rich pores, pressed using a special process. Activated carbon itself has a huge specific surface area and strong adsorption capacity, effectively adsorbing odors, harmful gases, and some tiny soluble impurities in the material to be filtered. After the material is initially filtered by the activated carbon filter plate 3, it flows through the filter paper 2 for further purification, improving the precision and quality of filtration.

[0034] A fixed filter plate 4 is fixedly connected inside the cylindrical filter chamber 1. The fixed filter plate 4 has a plate-like structure with numerous filter holes and is made of metal, such as stainless steel. Stainless steel fixed filter plates 4 are strong and corrosion-resistant, and can stably perform filtration within the cylindrical filter chamber 1 for a long time, initially filtering and intercepting larger particles while allowing the qualified liquid to continue flowing downwards. A rotating filter plate 5 is slidably connected to the outside of the fixed filter plate 4. The rotating filter plate 5 has a similar shape to the fixed filter plate 4 but is a rotatable plate-like structure, also made of stainless steel. The surface of the rotating filter plate 5 is also covered with filter holes. Rotation adjusts the size of the holes in the fixed filter plate 4 to accommodate different liquids requiring filtration. The top of the rotating filter plate 5 is fixed... Two rotating connecting columns 6 are connected. The rotating connecting columns 6 are slender cylindrical in shape and are made of high-strength alloy steel. They have good rigidity and strength and can rotate stably and transmit force under stress without bending or breaking. They provide a force base for the rotation of the rotating filter plate 5. The upper part of the rotating connecting column 6 is fixedly connected to a limiting rubber block 7. The limiting rubber block 7 is a block structure and is made of rubber with good elasticity and wear resistance, such as natural rubber. It limits the rotation range of the rotating connecting column 6 through friction, so that the fixed filter plate 4 will not rotate when stationary. The bottom of the limiting rubber block 7 is slidably connected to the top of the cylindrical filter cavity 1, and the top hole of the cylindrical filter cavity 1 is slidably connected to the outside of the rotating connecting column 6.

[0035] Reference Figure 1 , Figure 3 and Figure 5 The bottom of the cylindrical filter chamber 1 is fixedly connected to a filth hopper 8. The filth hopper 8 is a funnel-shaped container structure, with an inverted cone shape that is wider at the top and narrower at the bottom. It is made of metal, such as carbon steel, and can withstand the weight of a large number of impurities collected during the filtration process. Its surface is usually treated with anti-rust to adapt to the environment containing impurities such as moisture. The bottom of the filth hopper 8 is fixedly connected to a transport pipe 9. The transport pipe 9 is a long, strip-shaped tubular structure and is made of wear-resistant and corrosion-resistant metal, such as copper. It transports the impurities collected in the filth hopper 8 to the designated processing location. The outer middle of the transport pipe 9 is fixedly connected to a circular support frame 10. The circular support frame 10 is a ring-shaped bracket structure and is made of metal, such as aluminum alloy. It provides a mounting base for the drive components.

[0036] A drive assembly for quantitative material discharge is fixedly connected to the top of the annular support frame 10. The drive assembly includes a DC motor 11, which is cylindrical in shape and has a robust and well-ventilated metal casing. Internally, it houses a high-precision stator, rotor, windings, and bearings. The bottom of the DC motor 11 is fixedly connected to the top of the annular support frame 10. A connecting rotating shaft 12 is fixedly connected to the drive end of the DC motor 11. The connecting rotating shaft 12 is a slender cylindrical shape made of high-strength alloy steel and is used to transmit the rotational power of the DC motor 11. A quantitative rotating block 13 is fixedly connected to the outside of the rotating shaft 12. The quantitative rotating block 13 is a block structure with a specific shape and structure. Its material is metal, such as stainless steel. By controlling the rotation speed and angle of the quantitative rotating block 13, the flow rate of impurities can be precisely adjusted to achieve the function of quantitative discharge, ensuring that impurities can be transported out according to the set requirements to meet the needs of subsequent processing. The quantitative rotating block 13 is externally rotatably connected to the middle of the inside of the transport conveying pipe 9, and the middle of the inside of the transport conveying pipe 9 is rotatably connected to the outside of the rotating shaft 12.

[0037] Reference Figure 1 , Figure 2 and Figure 4 A power assembly providing moving cleaning force is fixedly connected to the top of the cylindrical filter chamber 1. The power assembly includes a cylinder 14. The outer shell of the cylinder 14 is made of a robust metal material with good sealing properties. The bottom of the cylinder 14 is fixedly connected to the top of the cylindrical filter chamber 1. A connecting telescopic column 15 is fixedly connected to the drive end of the cylinder 14. The connecting telescopic column 15 has a slender rod-like structure and is made of high-strength alloy steel, which allows the column 15 to move stably under the drive of the cylinder 14. A cross plate 16 is fixedly connected to the bottom of the connecting telescopic column 15. The cross plate 16 has a cross-shaped plate structure. Its unique cross shape looks like a regular and symmetrical "cross star" and can be moved relatively easily without putting too much burden on the entire power system. It also helps to improve the flexibility and accuracy of the cleaning operation. The outside of the cross plate 16 is fixedly connected to the inside of the cleaning sliding ring 17.

[0038] The power assembly is fixedly connected to a cleaning sliding ring 17. The cleaning sliding ring 17 has a ring-like structure, its shape being a smooth and regular "ring." It is made of stainless steel, a type of metal, which is high-strength and corrosion-resistant, not easily damaged, and maintains good structural integrity and working performance, providing reliable protection for long-term cleaning and maintenance. Multiple cleaning brushes 18 are fixedly connected to the upper and lower ends of the cleaning sliding ring 17. These brushes are made of fiber materials with good wear resistance and cleaning ability, such as nylon fiber. The bristles of the nylon fiber cleaning brushes 18 are soft and can easily reach deep cleaning surfaces. The cleaning brush 18 is inserted into the holes and crevices of the fixed filter plate 4 to remove impurities and dirt. The outside of the cleaning brush 18 is slidably connected to the inside of the fixed filter plate 4, and the inside of the fixed filter plate 4 is slidably connected to the outside of the cleaning scraper ring 19. The cleaning scraper ring 19 is fixedly connected to the middle of the outside of the cleaning sliding ring 17. The material is a wear-resistant metal material, such as alloy steel. The alloy steel cleaning scraper ring 19 has sufficient hardness and strength to effectively scrape off stubborn impurities on the surface of the fixed filter plate 4 that are not easily removed by the cleaning brush 18, and perform deep cleaning on its surface.

[0039] Working Principle: First, the material to be filtered enters the cylindrical filter chamber 1 and undergoes preliminary filtration through the fixed filter plate 4, intercepting any remaining larger particles. Then, the material continues to flow downwards into the activated carbon filter plate 3 for further filtration. The activated carbon effectively adsorbs odors, harmful gases, and some small soluble impurities from the material. Next, the material flows through the filter paper 2 for further purification, improving the filtration precision and quality. Simultaneously, to accommodate different liquids requiring filtration, the rotating connecting column 6 can be rotated left and right, causing the rotating filter plate 5 to rotate, thereby adjusting the mesh size of the fixed filter plate 4. A limiting rubber block 7 prevents the rotating filter plate 5 from rotating when stationary.

[0040] During the filtration process, the cylinder 14 is activated, causing the connecting telescopic column to move up and down inside the cylindrical filter chamber 1. This causes the cleaning sliding ring 17 connected to it to slide up and down on the inner surface of the fixed filter plate 4. Because the outer surface of the cleaning sliding ring 17 is covered with cleaning brushes 18, the impurities attached to the surface of the fixed filter plate 4 are cleaned. Furthermore, a cleaning scraper ring 19 further cleans stubborn impurities. The filtered impurities are collected in the filth hopper 8 and then transported to the designated processing location via the transport pipe 9. During transport, the DC motor 11 is activated, causing the connecting rotating shaft 12 to rotate. This drives the quantitative rotating block 13 to rotate regularly inside the transport pipe 9, achieving quantitative discharge of impurities to meet the needs of subsequent processing.

[0041] 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.
