Description

Technical Field

[0001] The utility model relates to the technical field of pleated filter elements, in particular to a multi-layer composite pleated filter element. Background Art

[0002] Multi-layer composite pleated filter elements are one type of filtration device among many. They offer high filtration precision, high flow rates, and the ability to effectively intercept tiny particles and colloidal debris. Some pleated filter elements are typically made from non-woven fabric using factory pleating machines. By folding the filter material into undulating peaks, these elements maximize the amount of filter material within the same space, trapping impurities and particulate matter on the filter surface and thus improving the purifier's filtration effectiveness.

[0003] The document with the existing authorization announcement number CN220530837U discloses a multi-layer composite pleated filter element, including a bottom plate; a filter element is fixedly connected to the center of the bottom plate, and a circular push plate is slidably connected to the outer side of the filter element; the outside of the filter element is slidably connected to the folded filter screen, and one end of the folded filter screen is in contact with the circular push plate; the outer side of the folded filter screen is slidably connected to multiple groups of circular clamping plates, and multiple groups of clamping grooves are arranged around the inside of the circular clamping plates; each group of the clamping grooves is in contact with the outer edges and corners of the folded filter screen; multiple groups of the circular clamping plates are fixedly connected by a first connecting rod, and one end of the first connecting rod passes through the inside of a group of the circular clamping plates and is connected to the circular push plate; the clamping grooves of the multiple groups of circular clamping plates correspond to the outer edges and corners of the folded filter screen, and the clamping grooves can support the outer side of the folded filter screen, thereby reducing the deformation of the folded filter screen under the impact of more turbulent water flow and improving the service life of the folded filter screen.

[0004] However, when this type of filter element is used, it has a better filtering effect on tiny particles and colloidal debris in the water body, but a poor filtering effect on harmful substances such as chlorine and chlorination by-products, heavy metals, arsenic and fluoride in the water body.

[0005] Therefore, it is necessary to provide a multi-layer composite pleated filter element to solve the above technical problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a multi-layer composite folded filter element that can filter water multiple times and has a better filtering effect.

[0007] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0008] The multi-layer composite pleated filter element comprises an outer cage frame with a water inlet cap threaded and sealed at its top. A first filter mechanism and a second filter mechanism are nested within the outer cage frame. The outer cage frame is sealed at its bottom. Water enters the first filter mechanism through the water inlet cap and undergoes a primary filtration process, removing chlorine, chlorination byproducts, heavy metals, arsenic, fluoride, and other harmful substances from the water. The water then enters the second filter mechanism, which performs a secondary filtration process. The filtered water is then discharged from the side of the outer cage frame. The first filter mechanism comprises a hexagonal first mounting frame with six activated carbon filter plates mounted on its sides. As the water passes through the activated carbon filter plates, harmful substances such as chlorine, chlorination byproducts, heavy metals, arsenic, and fluoride are adsorbed and removed. The activated carbon also has a deodorizing effect, removing odors from the water. The second filter mechanism comprises a second mounting frame with a multi-layer pleated filter screen mounted on its inner side. The multi-layer pleated filter screen is made of non-woven fabric or fine polypropylene fiber membrane.

[0009] Preferably, a plurality of plug holes are provided on the first mounting frame, and the activated carbon filter plate is inserted into the plug holes so that the activated carbon filter plate is plugged into the first mounting plate.

[0010] Preferably, the second mounting structure includes a plurality of gear rings, the inner sides of the gear rings are provided with conical teeth, and the plurality of gear rings are connected and fixed by connecting rods, and there are a plurality of connecting rods.

[0011] Preferably, a first limiting groove and a second limiting groove are provided at the bottom of the outer cage frame, the first limiting groove is adapted to the first mounting frame, and the second limiting groove is adapted to the gear ring.

[0012] Preferably, an integrally formed hexagonal plug-in portion is installed at the bottom of the water inlet cover, the plug-in portion is inserted into the inner side of the first mounting frame, and the outer side of the plug-in portion is sealed with the first mounting frame through a sealing ring, so as to position the top of the first mounting frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0030] Example 1:

[0031] like Figure 1-9 As shown, the multi-layer composite pleated filter element provided by the present invention includes: an outer cage frame 1, a water inlet cover 2 is threaded and sealed on the top of the outer cage frame 1, a first filter mechanism 3 and a second filter mechanism 4 are nested in the outer cage frame 1, the second filter mechanism 4 is arranged on the outside of the first filter mechanism 3, and the bottom of the outer cage frame 1 is closed. The water source enters the first filter mechanism 3 through the water inlet cover 2, and undergoes a first filtration through the first filter mechanism 3 to filter out chlorine and chlorination by-products, heavy metals, arsenic, fluoride and other harmful substances in the water, and then enters the second filter mechanism 4. The second filter mechanism 4 performs a second filtration on the water body. The second filter mechanism 4 can adopt the structure disclosed in CN220530837U, which adopts a multi-layer composite pleated filter screen. The specific structure will not be repeated here. The filtered water body is discharged from the side of the outer cage frame 1. The first filtering mechanism 3 includes a hexagonal first mounting frame 5, and six activated carbon filter plates 6 are installed on the side of the first mounting frame 5. When the water passes through the activated carbon filter plates 6, harmful substances such as chlorine and chlorination by-products, heavy metals, arsenic and fluoride in the water are adsorbed and removed, and the activated carbon has a deodorizing effect and can remove the odor of the water; the second filtering mechanism 4 includes a second mounting frame 7, and a multi-layer folded filter screen 8 is installed on the inner side of the second mounting frame 7. The multi-layer folded filter screen 8 is made of non-woven fabric or fine polypropylene fiber membrane material, and has the effect of intercepting tiny particles and colloidal debris. During use, water is fed into the inner side of the first mounting frame 5 through the water inlet cover 2, and then the water passes through the activated carbon filter plate 6 and is filtered by the activated carbon in the activated carbon filter plate 6 to remove various pollutants in the water, including organic pollutants, chlorine and chlorination by-products, taste and odor, heavy metals, arsenic and fluoride, micropollutants, colloids and suspended particles, etc. The water then enters the space between the first mounting frame 5 and the second mounting frame 7, and the water passes through the multi-layer folded filter screen 8 and is discharged outside the device. The multi-layer folded filter screen 8 performs secondary filtration on the water to improve the water filtration effect.

[0032] By arranging the outer cage frame 1, the water inlet cover 2, the first filtering mechanism 3 and the second filtering mechanism 4, the first filtering mechanism 3 is used to perform a first filtration on harmful substances such as chlorine and chlorination by-products, heavy metals, arsenic and fluoride in the water body, and then the second filtering mechanism 4 is used to perform a second filtration on the water body, thereby improving the filtering effect on the water body.

[0033] Example 2:

[0034] like Figure 3-4 As shown, a plurality of plug holes 9 are provided on the first mounting frame 5 , and the activated carbon filter plate 6 is inserted into the plug holes 9 so that the activated carbon filter plate 6 is plugged into the first mounting plate 5 , thereby facilitating the installation and removal of the activated carbon filter plate 6 .

[0035] The insertion hole 9 is provided on the first mounting frame 5 to facilitate installation and removal of the activated carbon filter plate 6 .

[0036] Example 3:

[0037] like Figure 5-6 As shown, the second mounting structure 7 includes a plurality of gear rings 10, the inner side of which is provided with conical teeth 12, and the plurality of gear rings 10 are connected and fixed by connecting rods 11. There are a plurality of connecting rods 11. When in use, the folded protrusions of the multi-layer folded filter 8 are embedded in the teeth 12 of the gear ring 10 for installation. The plurality of gear rings 10 are connected into a whole by the connecting rod 11 to support and fix the multi-layer folded filter 8 on the inner side. The water from the inner side squeezes the multi-layer folded filter 8. The outer gear rings 10 and the connecting rod 11 block the multi-layer folded filter, preventing the multi-layer folded filter 8 from being damaged by water pressure.

[0038] By providing a second mounting frame 7 including a gear ring 10 and a connecting rod 11 , the multi-layer pleated filter screen 8 can be supported and fixed.

[0039] Example 4:

[0040] like Figure 8 As shown, a first limiting groove 13 and a second limiting groove 14 are provided at the bottom of the outer cage 1. The first limiting groove 13 is adapted to the first mounting frame 5, and the second limiting groove 14 is adapted to the gear ring 10. When in use, a portion of the bottom of the gear ring 10 is inserted into the second limiting groove 14, and the bottom of the first mounting frame 5 is inserted into the first limiting groove 13, thereby positioning (limiting) the first mounting frame 5 and the second mounting frame 7, so that the first filter mechanism 3 and the second filter mechanism 4 are not easily moved in the outer cage 1.

[0041] By providing a first limiting groove 13 and a second limiting groove 14 at the bottom of the outer cage 1 , the first mounting frame 5 and the second mounting frame 7 can be positioned so that the first filter mechanism 3 and the second filter mechanism 4 are not easily moved in the outer cage 1 .

[0042] Example 5:

[0043] like Figure 9 As shown, an integrally formed hexagonal plug-in portion 15 is installed at the bottom of the water inlet cover 2. The plug-in portion 15 is inserted into the inner side of the first mounting frame 5. The outer side of the plug-in portion 15 is sealed with the first mounting frame 5 through a sealing ring. On the one hand, the top of the first mounting frame 5 can be positioned to make the state of the first mounting frame 5 more stable. On the other hand, the water of the water inlet cover 2 can enter the first mounting frame 5 without leakage. It is worth noting that the top of the second mounting frame 7 and the water inlet cover 2 are also sealed.

[0044] By providing the plug-in portion 15 on the water inlet cover 2 , one end of the first mounting frame 5 can be conveniently positioned, so that the state of the first mounting frame 5 in the outer cage frame 1 is more stable.

[0045] Working principle: When in use, the water source is sent into the inner side of the first mounting frame 5 through the water inlet cover 2, and then the water source passes through the activated carbon filter plate 6, and is filtered by the activated carbon in the activated carbon filter plate 6 to remove various pollutants in the water, including organic pollutants, chlorine and chlorination by-products, taste and odor, heavy metals, arsenic and fluoride, micropollutants, colloids and suspended particles, etc., and then the water body enters the space between the first mounting frame 5 and the second mounting frame 7, and the water body passes through the multi-layer folded filter screen 8 and is discharged to the outside of the device. The multi-layer folded filter screen 8 performs secondary filtration on the water body to improve the water filtration effect.
