Description

Technical Field

[0001] This utility model relates to the field of filter elements, and more specifically, to a filter element made of nanofiber material. Background Technology

[0002] Currently, filter cartridges that can achieve sterilization require highly uniform pore sizes, all below 0.5 micrometers. However, such high-precision pore size results in very low flow rates and makes the cartridges prone to clogging. To address the flow rate issue caused by the small pore size, increasing the surface area of ​​the filter cartridge is generally chosen. However, this leads to an increase in the size of the filter cartridge, and it also makes the cartridge more susceptible to clogging by particulate matter and colloids in the water.

[0003] The utility model patent application CN208603867 discloses a filter element comprising a central column and a filter layer, wherein the filter layer is folded and arranged around the circumference of the central column; the central column has flow guide holes for discharging liquid filtered by the filter layer; the filter layer, relative to the central column, comprises an inner support layer, an inner filter layer, and an outer filter layer from the inside out; the inner support layer, the inner filter layer, and the outer filter layer are sequentially pressed together; the inner filter layer and the outer filter layer are made of intertwined nanofiber material. This utility model's filter element, using nanofiber material, can improve the filter element's dirt-holding capacity and sterilization capacity, and effectively alleviates filter element clogging problems without reducing the pore size.

[0004] The above-disclosed structure uses a folded arrangement of the filter media, forming a single-layer filtration structure. It lacks the spiral winding of the filter to form a multi-functional filtration system, resulting in poor filtration performance. Furthermore, it is impossible to disassemble the filter media for partial replacement and maintenance. The filter media is also prone to deformation and leakage due to impact, and its stability is insufficient, requiring improvement. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a nanofiber material filter element. Through different connecting rings inside the perforated tube, it can be combined and positioned. By winding the filter belt around the edge, combined with the inner nanofiber layer and reinforcing fibers, the spiral structure can form a multi-layer filter structure. At the same time, it fits tightly with the perforated inner tube, ensuring structural strength, preventing deformation and leakage, ensuring safety and stability, good filtration effect, and being easy to disassemble and rewind, which is convenient for replacement and maintenance.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A nanofiber filter element includes a perforated inner cylinder with mounting rings fixedly connected to both ends. A filter belt is spirally wound on the outer surface of the inner cylinder. A limiting ring is fixedly connected to one side of the mounting ring and is fixedly sleeved on both ends of the filter belt. A nanofiber layer is provided on one side of the filter belt, and reinforcing fibers are fixedly embedded inside the filter belt. The reinforcing fibers are arranged at equal intervals along the length of the filter belt. A combination groove is provided on one end surface of the mounting ring, and a through hole is provided in the center of the combination groove. An annular groove is provided on the inner side of the combination groove, and a connecting ring is engaged on the inner side of the combination groove. An annular head is fixedly connected to the outer surface of the connecting ring and is elastically engaged inside the annular groove.

[0008] Furthermore, a connecting rod is fixedly connected to the inner surface of the connecting ring, and the connecting rod is attached to the inner surface of the through hole.

[0009] Furthermore, one end of the connecting rod is provided with an elastic clearance notch, which is located on one side inside the connecting ring.

[0010] Furthermore, there are three connecting rods, which are evenly distributed circumferentially on the inner side of the connecting ring. By unevenly distributing the connecting rods on the connecting ring, they can be installed and positioned separately, thereby providing internal elastic support and reinforcement, improving structural strength and stability, and facilitating combined use.

[0011] Furthermore, a support plate is fixedly connected to one end of the connecting rod, and the support plate is inserted into the interior of the perforated inner cylinder.

[0012] Furthermore, one side surface of the support plate is provided with an arc-shaped surface, which is tightly connected to the inner wall surface of the perforated inner cylinder.

[0013] Furthermore, the support plates are connected at equal angles to the inside of the perforated inner cylinder and are symmetrically distributed at both ends of the perforated inner cylinder. By setting the arc-shaped surface of the support plates, they can be pressed tightly against the side wall of the perforated inner cylinder, which can provide auxiliary support, reduce deformation and damage, and improve structural safety.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can be combined and positioned by different connecting rings with holes. By wrapping the filter belt around the edge, combined with the inner nanofiber layer and reinforcing fiber, the spiral structure can form a multi-layer filter structure. At the same time, it is tightly attached to the inner cylinder with holes to ensure structural strength, avoid deformation and leakage, and is safe, stable, and has a good filtration effect. It is also convenient to disassemble and rewrap, which is conducive to replacement and maintenance.

[0016] (2) By connecting the ring with unevenly distributed connecting rods, the parts can be installed and positioned separately, thereby strengthening the structure from the inside with elastic support, improving the structural strength and stability, and facilitating combined use.

[0017] (3) By setting the arc surface of the support plate, it can be pressed against the side wall of the perforated inner cylinder, which can provide auxiliary support, reduce deformation and damage, and improve structural safety. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 3 and Figure 4A nanofiber filter element includes a perforated inner cylinder 1, with mounting rings 11 fixedly connected to both ends of the perforated inner cylinder 1. A filter belt 12 is spirally wound onto the outer surface of the perforated inner cylinder 1. Spiraling the filter belt 12 onto the outer surface of the perforated inner cylinder 1 forms a multi-layer structure, thus creating a multi-layer filtration system. This improves structural stability, prevents impact damage, facilitates easy installation, and allows for direct disassembly and replacement for maintenance. New filter belts 12 can then be wound, facilitating reuse of the perforated inner cylinder 1, reducing operating costs, and providing high adaptability. A limiting ring 13 is fixedly connected to one side of the mounting rings 11, and the limiting ring 13 is fixedly sleeved onto both ends of the filter belt 12. A nanofiber layer 15 is provided on one side of the filter belt 12, and reinforcing fibers 1 are fixedly embedded inside the filter belt 12. 4. The strength of the filter belt 12 is improved by reinforcing the fiber 14, reducing deformation and damage and preventing leakage. The nanofiber layer 15 can enhance the filtration effect, reduce the pore size of the filter, and facilitate combined use. The reinforcing fiber 14 is arranged at equal intervals along the length of the filter belt 12. One end of the mounting ring 11 is provided with a combination groove 16. The inside of the combination groove 16 is provided with a through hole 17 in the middle. The inner side of the combination groove 16 is provided with an annular groove 18. The inner side of the combination groove 16 is fitted with a connecting ring 2. The outer surface of the connecting ring 2 is fixedly connected with an annular head 21. The annular head 21 is elastically fitted into the inside of the annular groove 18. The connecting ring 2 can be directly pressed down and installed into the inside of the combination groove 16, and then the annular head 21 is elastically fitted into the inside of the annular groove 18, which is conducive to separate installation and positioning and combined use.

[0027] Please see Figure 2 and Figure 3 A connecting rod 22 is fixedly connected to the inner surface of the connecting ring 2. The connecting rod 22 fits against the inner surface of the through hole 17. One end of the connecting rod 22 is provided with an elastic clearance notch 23, which is located on one side inside the connecting ring 2. There are three connecting rods 22, which are distributed circumferentially at equal angles on the inner side of the connecting ring 2. By unevenly distributing the connecting rods on the connecting ring, they can be installed and positioned separately, thereby providing internal elastic support and reinforcement, improving structural strength and stability, and facilitating combined use.

[0028] Please see Figure 3 and Figure 5One end of the connecting rod 22 is fixedly connected to a support plate 24. The support plate 24 is inserted into the interior of the perforated inner cylinder 1. One side surface of the support plate 24 is provided with an arc-shaped surface 25. The arc-shaped surface 25 is tightly connected to the inner wall surface of the perforated inner cylinder 1. The support plates 24 are connected to the interior of the perforated inner cylinder 1 at equal angles and are symmetrically distributed at both ends of the perforated inner cylinder 1. By setting the arc-shaped surface of the support plate, it can be tightly pressed against the side wall of the perforated inner cylinder, which can assist in support, reduce deformation and damage, and improve structural safety. During installation, the three support plates 24 can be elastically deformed in conjunction with the connecting rod 22, which can shrink towards the center position. After reducing the diameter, they can be inserted into the through hole 17 and then into the interior position of the perforated inner cylinder 1. Then, they can be elastically reset, and the arc-shaped surface 25 can be attached to the inner surface of the perforated inner cylinder 1, which can assist in support and reinforcement, reduce deformation and leakage, and ensure filtration stability.
