Description

Technical Field

[0001] This utility model relates to the field of filter felt pad technology, specifically a gradient pore self-cleaning filter felt pad. Background Technology

[0002] As is well known, filter felt pads are a widely used filter material in industrial fields. They are made of wool or synthetic fibers such as polyester through needle punching to form a dense and porous nonwoven fabric structure, thereby achieving the function of filtration and separation. Traditional filter felt pads are mostly single-layer structures or have uniformly distributed pores, making it difficult to achieve step-by-step interception from large particles to small particles. This leads to a high risk of deep clogging, a rapid increase in pressure drop, and a short filtration cycle. Moreover, they all require regular cleaning. However, existing filter felt pads rely on manual cleaning with tools or chemical agents, which is cumbersome and costly. Incomplete cleaning can also leave contaminants, affecting subsequent filtration performance. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

The outer layer has a pore size range of 50-200μm, the middle layer has a pore size range of 10-50μm, and the inner layer has a pore size range of 0.1-10μm. A support frame is provided between the outer layer and the middle layer. A quick connector is provided at one end of the support frame.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a gradient pore self-cleaning filter felt pad, which has the following beneficial effects:

[0014] This gradient pore self-cleaning filter felt pad has an outer layer that acts as the first barrier, intercepting large particles such as silt and suspended solids, reducing the load on subsequent layers. The middle layer intercepts medium-sized particles such as colloids and microorganisms, balancing filtration efficiency and clogging risk through appropriate pore density. The inner layer captures extremely fine particles, ensuring the purity of the final fluid and significantly extending the overall filtration cycle. The spiral tube is arranged inside the support frame, with multiple flushing holes evenly distributed to ensure water flow covers the entire outer layer area. The hydrophobic coating reduces the surface energy of the outer layer, reducing the adhesion of contaminants such as oil and significantly reducing the cleaning frequency. Through the synergistic effect of spiral tube flushing and hydrophobic coating, the self-cleaning ability is significantly improved, reducing manual intervention. Users only need to connect an external flushing pipe and provide flushing fluid such as water or add cleaning fluid to complete the efficient cleaning operation, eliminating the need for complex tools and manual operation.

[0020] 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.

[0021] Please see Figures 1-4 This utility model relates to a gradient pore self-cleaning filter felt pad, comprising a multi-layer gradient pore felt substrate. The multi-layer gradient pore felt substrate consists of an outer layer 1, a middle layer 2, and an inner layer 3, arranged sequentially from the outside inwards. The outer layer 1 has a pore size range of 50-200 μm, the middle layer 2 has a pore size range of 10-50 μm, and the inner layer 3 has a pore size range of 0.1-10 μm. A support frame 4 is provided between the outer layer 1 and the middle layer 2. One end of the support frame 4 has a quick connector 5. A spiral tube 6 is provided between the support frame 4 and the interior of the middle layer 2. The spiral tube 6 is equipped with... The flushing holes 7 are provided in multiple locations. A flushing mechanism is provided between the quick connector 5 and the support frame 4. The outer layer 1 is provided with a hydrophobic coating 8. In this embodiment, the outer layer with a pore size of 150-200μm serves as the first filtration barrier, intercepting large particles such as silt and suspended solids, reducing the load on the middle layer 2 and inner layer 3. The middle layer with a pore size of 10-50μm processes medium-sized particles such as colloids and microorganisms, balancing filtration efficiency and clogging risk through a structure with appropriate pore density. The inner layer with a pore size of 30.1-10μm is a precision filtration layer, capturing extremely fine particles to ensure the high purity of the final fluid. The support frame 4 is quickly connected and fixed to an external flushing pipe via the quick connector 5. The quick connector 5 is a common standardized interface. The spiral tube 6 is arranged inside the support frame 4, and water is sprayed onto the outer layer 1 of the substrate through the flushing holes 7 to achieve efficient removal of surface dirt. The annular structure of the spiral tube 6 ensures that the flushing water covers the entire area of ​​the outer layer 1, avoiding local blockage. Through the middle layer 2, impurities in the outer layer 1 and the inner side can be efficiently flushed away. Furthermore, the flushing mechanism can further improve the flushing efficiency of the outer layer 1. The hydrophobic coating 8 reduces the adhesion of contaminants such as oil stains and extends the filtration cycle. Combined with the flushing mechanism, the hydrophobic coating 8 can reduce dirt residue and improve flushing efficiency. Personnel only need to flush the pipe from the outside and provide flushing liquid, such as water or adding cleaning fluid to the water, to achieve the self-cleaning operation of this structure, which greatly reduces the time-consuming cleaning by personnel using various tools.

[0022] To achieve more efficient rinsing of the outer layer 1, the rinsing mechanism in this design includes a support frame 9 and a connecting pipe 10. The support frame 9 is installed between the outer layer 1 and the middle layer 2. The support frame 9 has openings, and multiple elastic tubes 11 are installed on the openings. The connecting pipe 10 is installed at the top of the quick connector 5 and connects to the multiple elastic tubes 11. The support frame 9, installed between the outer layer 1 and the middle layer 2, provides stable support for the elastic tubes 11 and the connecting pipe 10. The multiple openings allow the elastic tubes 11 to deform and bend flexibly to adapt to the irregular deformation of the outer layer 1 surface. If common elastic materials such as rubber or silicone are used for the elastic tubes 11, they can adjust their shape according to the undulations of the outer layer 1 surface to ensure uniform coverage of the rinsing water. Multiple elastic tubes 11 work simultaneously to improve rinsing coverage and efficiency. The connecting pipe 10 distributes the water source of the quick connector 5 to each elastic tube 11, achieving centralized power supply and decentralized rinsing.

[0023] To improve wear resistance, in this design, a wear-resistant layer 12 is provided between the hydrophobic coating 8 and the outer layer 1. The wear-resistant layer 12 is located between the hydrophobic coating 8 and the outer layer 1, absorbing external friction forces such as scrapers and particle impacts to reduce wear.

[0024] To avoid localized siltation, in this design, the outer layer 1 is provided with corrugated grooves 13. The corrugated grooves form micro-vortices, which enhance the scouring effect of the fluid on the surface of the outer layer 1, help remove attached contaminants, guide the water flow direction through the grooves, avoid localized siltation, reduce the formation of dead zones, and the corrugated design can alleviate the deformation stress of the outer layer 1 caused by pressure or thermal expansion and contraction, thereby improving the overall mechanical strength.

[0025] In order to improve the service life of this structure, in this solution, the bottom end of the inner layer 3 is provided with an anti-aging layer 14. The anti-aging layer 14 is located at the bottom end of the inner layer 3, resisting environmental factors such as acid and alkali corrosion and ultraviolet radiation, and extending the service life of the substrate.

[0026] To improve antibacterial performance, an antibacterial layer 15 is provided between the middle layer 2 and the inner layer 3 in this design. The antibacterial layer 15, located between the middle layer 2 and the inner layer 3, inhibits the growth of bacteria, algae, and other microorganisms through antibacterial agents such as silver ions and quaternary ammonium salts. This prevents microbial membranes from clogging the pores and ensures that the middle layer 2 and the inner layer 3 maintain their filtration capacity over the long term.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
