Description

Technical Field

[0001] This utility model relates to the field of melt filtration technology, and in particular to a fan-shaped pleated filter element. Background Technology

[0002] In melt processing, metal filters play a crucial role, primarily removing impurities from the molten metal to protect the spinneret. Even very small impurities can clog the spinneret orifices, forcing the manufacturer to replace the spinneret and potentially causing the entire production line to shut down, resulting in significant economic losses. Figure 1 As shown, metal filter elements typically consist of a support frame and a filter mesh layer, with the filter mesh layer being the core component for achieving the filtration function.

[0003] However, existing metal filter elements have some defects and shortcomings in practical applications:

[0004] First, such as Figure 1 As shown, the pleated structure of the filter mesh of a traditional pleated filter element is usually a parallel structure, which can easily form a stagnant zone during the melt flow process, affecting the filtration efficiency.

[0005] Secondly, the unreasonable design of the through-hole structure on the support frame results in poor melt flow and inability to be thoroughly cleaned after use, which in turn shortens the service life of the filter element and increases the replacement frequency and production cost.

[0006] Therefore, there is an urgent need to develop a new type of filter element structure that can improve the melt flow path, reduce the formation of stagnant zones, improve filtration efficiency, and at the same time facilitate cleaning and extend service life. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a fan-shaped corrugated filter element to solve the problems in the prior art where the pleated filter cloth has a melt flow retention area that affects the filtration efficiency and the support skeleton has poor melt flowability and cannot be thoroughly cleaned.

[0008] To achieve the above and other related objectives, this utility model provides a fan-shaped pleated filter element, including a support frame and a filter mesh layer. The support frame is in the shape of a hollow tube and has multiple through holes for the melt to pass through. The filter mesh layer is folded into fins and surrounds the outer periphery of the support frame. The cross-section of each fin is a curved fan-shaped structure.

[0009] As a preferred embodiment of this invention, each of the fins has the same shape and is evenly spaced on the outer periphery of the support frame to ensure uniform distribution of the filtration area and improve filtration efficiency.

[0010] As a preferred technical solution of this utility model, the filter mesh layer is made of metal mesh, which ensures the strength and durability of the filter element.

[0011] As a preferred technical solution of this utility model, the metal mesh is cut and arranged according to the filter mesh number, and then arranged by a wave-forming machine to form a fan-shaped zigzag structure, so that the filter mesh layer can form a uniform fan-shaped zigzag structure.

[0012] As a preferred embodiment of this invention, the through hole is tapered, which improves the flow properties of the melt.

[0013] As a preferred embodiment of this invention, the diameter of the inlet end of the conical hole is larger than the diameter of its outlet end, forming a flow guiding structure, which is conducive to the smooth passage of the melt.

[0014] As a preferred embodiment of this invention, the tapered holes are evenly spaced on the support frame to ensure that the melt passes through the filter element uniformly and improve filtration efficiency.

[0015] As described above, the fan-shaped pleated filter element of this utility model has the following beneficial effects:

[0016] 1. The filter mesh layer of this utility model adopts a fan-shaped corrugated structure design, which avoids the formation of melt flow stagnation zone in the traditional corrugated structure, so that the melt can pass through the filter element more smoothly and improve the filtration efficiency.

[0017] 2. The tapered through-hole design on the support frame improves the flow properties of the melt and greatly increases the melt throughput.

[0018] 3. The overall fan-shaped zigzag candle core filter element structure facilitates the cleaning of filtered impurities, solving the defects of existing filter elements that are not clean and have short replacement cycles, reducing production costs and improving production efficiency;

[0019] Compared with the prior art, the fan-shaped pleated filter element of the present invention has a simple structure, low manufacturing cost, good performance, and good application prospects. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Example 1

[0029] Please see Figure 2-4 This embodiment provides a fan-shaped pleated filter element, including a support frame 1 and a filter mesh layer 2. The support frame 1 is a hollow tube, and has multiple through holes 3 for the melt to pass through. These through holes 3 are designed with a conical shape, with the diameter of the inlet end of the conical hole being larger than the diameter of its outlet end, so that the melt can flow smoothly from the inlet to the outlet, reducing the resistance of the melt during the passage process. These conical holes are evenly spaced on the support frame to ensure that the melt can be evenly distributed through the entire filter element, thereby improving the filtration efficiency.

[0030] The filter mesh layer 2 is folded into fins and then placed around the outer periphery of the support frame 1. Each fin has a curved fan-shaped cross-section, such as... Figure 2-5 As shown in the diagram. This fan-shaped structure design increases the filtration area and improves filtration efficiency; it also guides the melt to flow towards the inside of the filter element, preventing the filtered melt from remaining on the outside.

[0031] Each fin has a consistent shape and is evenly spaced around the outer perimeter of the support frame, ensuring consistent and stable filtration performance. The uniform distribution of the fins also ensures that the melt experiences uniform resistance as it passes through the filter element, preventing excessive localized pressure that could deform or damage the filter element.

[0032] The filter mesh layer 2 is made of metal mesh, which has excellent high-temperature resistance and mechanical strength, enabling it to maintain stable filtration performance in high-temperature molten environments. After being cut and arranged according to the required mesh size, the metal mesh is then wave-formed into a fan-shaped corrugated structure using a wave-forming machine. Different mesh sizes can be selected according to actual needs to meet the filtration precision requirements of different melts.

[0033] During the manufacturing process, a metal mesh of appropriate mesh size is first selected as needed, and then cut to the predetermined dimensions. The cut metal mesh is then processed by a corrugating machine to form a uniform fan-shaped corrugated structure. Subsequently, the corrugated metal mesh is wrapped around the outer perimeter of the support frame and fixed in the appropriate position to form a complete fan-shaped corrugated filter element.

[0034] The working principle of this fan-shaped corrugated filter element is as follows: the molten material enters through the conical through-hole 3 of the supporting frame 1, and then is filtered through the filter mesh layer 2 of the fan-shaped corrugated structure. (Reference) Figure 5 The fan-shaped structure increases the filtration area and improves filtration efficiency; moreover, multiple fan shapes guide the melt to flow inward, further improving flow efficiency and reducing stagnation. The tapered through-hole design reduces melt flow resistance and prevents clogging; the evenly distributed fins and through-holes ensure consistent filtration performance.

[0035] Example 2

[0036] This embodiment provides a fan-shaped corrugated filter element, including a support frame 1 and a filter mesh layer 2. The support frame 1 is a hollow tube, and has multiple through holes 3 for the melt to pass through. These through holes 3 are designed with a conical shape, with the diameter of the inlet end of the conical hole being larger than the diameter of its outlet end, so that the melt can flow smoothly from the inlet to the outlet, reducing the resistance of the melt during the passage process. These conical holes are evenly spaced on the support frame to ensure that the melt can be evenly distributed through the entire filter element, thereby improving the filtration efficiency.

[0037] The filter mesh layer 2 is folded into fins and then placed around the outer periphery of the support frame 1. Each fin has a curved fan-shaped cross-section, such as... Figure 2-5 As shown in the diagram. This fan-shaped structure design increases the filtration area and improves filtration efficiency; it also guides the melt to flow towards the inside of the filter element, preventing the filtered melt from remaining on the outside.

[0038] Each fin has a consistent shape and is evenly spaced around the outer perimeter of the support frame, ensuring consistent and stable filtration performance. The uniform distribution of the fins also ensures that the melt experiences uniform resistance as it passes through the filter element, preventing excessive localized pressure that could deform or damage the filter element.

[0039] Furthermore, the spacing inside the fins is greater than or equal to the spacing between two adjacent fins.

[0040] Furthermore, the thickness of the filter mesh layer 2 after being folded into fins is 2 to 6 times the thickness of the support frame 1. Preferably, the thickness of the filter mesh layer 2 after being folded into fins is 3 times the thickness of the support frame 1, which can provide sufficient support and ensure an appropriate filtration path, reducing external retention of melt.

[0041] Furthermore, the filter mesh layer 2 is made of stainless steel mesh. Stainless steel has better corrosion resistance and high temperature resistance, making it suitable for filtering various corrosive melts. The mesh size can be selected between 60 and 200 meshes according to actual filtration needs; the higher the mesh size, the higher the filtration accuracy.

[0042] During the manufacturing process, a metal mesh of appropriate mesh size is first selected as needed, and then cut to the predetermined dimensions. The cut metal mesh is then processed by a corrugating machine to form a uniform fan-shaped corrugated structure. Subsequently, the corrugated metal mesh is wrapped around the outer perimeter of the support frame and fixed in the appropriate position to form a complete fan-shaped corrugated filter element.

[0043] In summary, the filter mesh layer of this invention, with its fan-shaped corrugated structure, avoids the formation of stagnation zones in the melt flow characteristic of traditional corrugated structures, allowing the melt to pass through the filter element more smoothly and improving filtration efficiency. The conical through-hole design on the support frame improves the melt flow properties, significantly increasing the melt throughput. Furthermore, the overall fan-shaped corrugated filter element structure facilitates cleaning of filtered impurities, solving the problems of incomplete cleaning and short replacement cycles in existing filter elements, reducing production costs and improving production efficiency. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.
