Description

Technical Field

[0001] The utility model relates to the technical field of water filter elements, in particular to a laminated large-flux water filter element. Background Art

[0002] High-flow water filter elements are filter elements specially designed to handle large-flow water purification needs. They are widely used in industrial, commercial and large residential water treatment systems to efficiently remove suspended solids, microorganisms, colloids and other impurities in water, thereby improving water quality.

[0003] Water treatment filters are increasingly used. As the core component of the filter, the filter element needs to be replaced when the pressure difference or usage time reaches the requirement. Since the current filter element structure is an integrated structure, the replacement and maintenance costs are relatively high. Utility Model Content

[0004] The utility model aims to provide a laminated large-flux water filter element, which changes an integrated filter element into a laminated structure, and each laminate can be replaced individually, avoiding waste caused by replacing the entire filter element when the filter element is blocked.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laminated large-flux water filter element, comprising a central tube, a top connecting shell is fixed on the top of the central tube, a connecting plate is fixed on the bottom of the central tube, a bottom connecting shell is detachably connected to the bottom of the central tube, a plurality of supporting frames are slidably connected to the surface of the central tube, water holes are provided on the surfaces of the central tube and the supporting frames, a first filter material is fixed on the surface of the supporting frames, a second filter material is fixed on the surface of the first filter material, a top closing cover is fixed above the surface of the supporting frames, a bottom closing cover is fixed below the surface of the supporting frames, an extension plate is fixed to the bottom of the bottom closing cover and the top of the inner wall of the top connecting shell, a combination groove is provided on the top of the top closing cover and the bottom of the inner wall of the bottom connecting shell, a first sealing gasket is fixed on the surface of the extension plate, and a sealing groove is provided on the top closing cover and the surface of the top connecting shell.

[0006] As a preferred laminated large flux water filter element of the utility model, the central tube and the support frame surface both have a plurality of water holes, and the plurality of water holes are equidistantly distributed in a ring shape.

[0007] As a preferred laminated large-flux water filter element of the utility model, the surface of the connecting plate is provided with threads, the inner wall of the bottom connecting shell is provided with thread grooves used in conjunction with the connecting plate, and the connecting plate and the bottom connecting shell are detachably connected via threads.

[0008] As a preferred laminated large-flux water filter element of the utility model, the first filter material is a PP melt-blown filter element.

[0009] As a preferred laminated large-flux water filter element of the utility model, the second filter material is a polytetrafluoroethylene filter element.

[0010] As a preferred embodiment of the laminated large-flux water filter element of the utility model, a second sealing gasket is fixed to the inner wall of the top connecting shell and the inner wall of the bottom connecting shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] In the utility model, water flows into through the central tube and is dispersed into the first filter material through the water holes. After the water flows through the first filter material and the second filter material, it is discharged outward. When it is necessary to replace the filter material on the surface of a certain support frame, the bottom connection shell is firstly taken out from the surface of the connection plate, so that the bottom of the central tube is in an open state. At this time, the support frame on one side can be directly pulled through the bottom closing cover, and the support frame can carry the first filter material and the second filter material on its surface to be removed from the surface of the central tube, and then the replacement process can be carried out, so that the device does not need to replace the entire filter element material, thereby reducing the equipment maintenance cost. When the support frames on both sides are combined with each other, the extension plate below the surface of the upper bottom closing cover will enter the combination groove on the surface of the lower top closing cover, and the first sealing gasket will be compressed and deformed and enter the sealing groove, thereby improving the connection strength and sealing performance between the extension plate and the combination groove, and preventing water from flowing out from the gap between the two support frames. At the same time, when the top of the most comfortable support frame contacts the bottom of the inner wall of the top connection shell, the extension plate on the surface of the top connection shell will also enter the combination groove, thereby improving the sealing between the support frame and the top connection shell.

[0020] Water flows in through the central tube 1 and is dispersed into the first filter material 7 through the water holes 6. The water flows out after being filtered by the first filter material 7 and the second filter material 8. When it is necessary to replace the filter material on the surface of a certain support frame 5, first remove the bottom connection shell 4 from the surface of the connecting plate 3 to make the bottom of the central tube 1 open. At this time, the support frame 5 on one side can be directly pulled through the bottom closing cover 10. The support frame 5 can carry the first filter material 7 and the second filter material 8 on its surface and remove them from the surface of the central tube 1. Then, the replacement process can be carried out, so that the device does not need to replace the entire filter element material, thereby reducing the equipment maintenance cost. In this embodiment, when the support frames 5 on both sides are combined with each other, the extension plate 11 below the surface of the upper bottom closing cover 10 will enter the combination groove 12 on the surface of the lower top closing cover 9, and at the same time, the first sealing gasket 13 will be compressed and deformed and enter the sealing groove 14, thereby improving the connection strength and sealing performance between the extension plate 11 and the combination groove 12, and preventing water from flowing out from the gap between the two support frames 5. At the same time, when the top of the most comfortable support frame 5 contacts the bottom of the inner wall of the top connecting shell 2, the extension plate 11 on the surface of the top connecting shell 2 will also enter the combination groove 12, thereby improving the sealing between the support frame 5 and the top connecting shell 2.

[0021] Furthermore, the number of water holes 6 on the surface of the central tube 1 and the support frame 5 is multiple, and the multiple water holes 6 are distributed in an annular shape with equal distances;

[0022] The equidistantly distributed water holes 6 can ensure that the fluid is evenly distributed on the entire surface of the first filter material 7, avoiding local overload, thereby improving the filtration efficiency and the service life of the filter element.

[0023] Furthermore, the surface of the connecting plate 3 is provided with threads, and the inner wall of the bottom connecting shell 4 is provided with thread grooves used in conjunction with the connecting plate 3, and the connecting plate 3 and the bottom connecting shell 4 are detachably connected through threads;

[0024] This design ensures that the connecting plate 3 can be disassembled from the bottom connecting shell 4, and no tools are needed during the disassembly process, thereby improving replacement efficiency.

[0025] Furthermore, the first filter material 7 is a PP melt-blown filter element;

[0026] PP melt-blown filter elements have excellent chemical stability and can resist corrosion from most acids, alkalis and solvents. They are suitable for removing larger particles. Polypropylene materials are relatively cheap and the production process is simple, which can reduce costs.

[0027] Furthermore, the second filter material 8 is a polytetrafluoroethylene filter element;

[0028] PTFE has excellent oxidation and weather resistance and is not easily degraded, which means the filter element has a long service life, reducing replacement frequency and maintenance costs.

[0029] Furthermore, a second sealing gasket 15 is fixed to the inner wall of the top connection shell 2 and the bottom connection shell 4;

[0030] The second sealing gasket 15 can enhance the sealing between the top connecting shell 2 and the top closing cover 9, and the sealing between the bottom connecting shell 4 and the bottom closing cover 10, thereby preventing water from leaking through the gaps.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
