Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a novel scale-inhibiting filter element structure. Background Technology

[0002] In the field of water treatment equipment, the mainstream scale-inhibiting filter cartridges on the market generally adopt a structural design that simply stacks the scale-inhibiting filter media in the container channel. This traditional design, in principle, relies on the water flow within the container contacting the statically stacked filter media. The active ingredients in the filter media react chemically with calcium and magnesium ions in the water, thereby preventing scale formation. However, the tightly stacked filter media in existing cartridges means that the water flow can only contact the surface layer of the filter media, making it difficult for the internal filter media to fully contact the water and effectively inhibit scale formation. Furthermore, the filter media cannot flow freely in the fixed container, failing to increase the contact area and force with the water through movement, resulting in low scale inhibition efficiency. This not only wastes filter media but also significantly increases product manufacturing costs. Therefore, we propose a novel scale-inhibiting filter cartridge structure. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a novel scale-inhibiting filter element structure. This invention solves the problems of existing filter elements where the internal filter media is tightly stacked, causing water flow to only contact the surface layer of the media, making it difficult for the internal media to fully contact the water and effectively inhibit scale growth. Furthermore, the filter media cannot flow freely within a fixed container, preventing movement and thus limiting its contact area and force with the water, resulting in low scale inhibition efficiency, wasted filter media, and significantly increased production costs.

[0004] This utility model discloses a novel scale-inhibiting filter element structure, comprising a tube body, an inlet end cap on one side of the tube body, an outlet end cap on the side of the tube body away from the inlet end cap, a filter cylinder inside the tube body near the outlet end cap, a filter element core inside the filter cylinder, and multiple filter media mesh assemblies inside the tube body, with multiple equally spaced filter media spiral guide assemblies between two adjacent filter media mesh assemblies.

[0005] The filter media spiral guide assembly includes a first connecting pipe, a fixing plate in the middle of the first connecting pipe, four spiral blades arranged in a matrix on both sides of the fixing plate, the spiral directions of the spiral blades on both sides of the fixing plate are the same, the outer side of the spiral blades is fixedly connected to the fixing plate through a support plate, the upper surface of the spiral blades is provided with a plurality of protrusions arranged in a matrix, and a second connecting pipe is provided below the first connecting pipe.

[0006] In the above scheme, the filter media mesh assembly includes an outer connecting ring, an inner connecting ring is provided in the middle of the outer connecting ring, a fixing ring is provided between the outer connecting ring and the inner connecting ring, multiple ultrasonic lines are arranged in a matrix between the outer connecting ring and the fixing ring and between the inner connecting ring and the fixing ring, a baffle is provided between adjacent ultrasonic lines, and multiple equidistant guide grooves are opened on the baffle. A slot matching the second connecting pipe is provided on one side of the inner connecting ring, and a positioning pipe is provided on the side of the inner connecting ring away from the slot 67.

[0007] In the above scheme, the upper end of the spiral blade is fixedly connected to the first connecting pipe through a flat reinforcing plate.

[0008] In the above scheme, the cross-section of the baffles on both sides of the fixed ring is conical.

[0009] In the above scheme, the outer surface of the spiral blade is provided with an orange-textured surface.

[0010] In the above scheme, the filter element is a PPF filter element or an activated carbon filter element.

[0011] In the above scheme, O-rings or waterproof sealant are provided between the water inlet end cap and the pipe body, and between the water outlet end cap and the pipe body.

[0012] In the above scheme, the inlet end cap and the pipe body are sealed by spin welding or ultrasonic wave, as are the outlet end cap and the pipe body.

[0013] The advantages and beneficial effects of this utility model are as follows: This utility model provides a novel scale-inhibiting filter element structure. The arrangement of multiple filter media mesh components creates multiple regions inside the tube, allowing different types of filter media to be placed in different regions during use, thus effectively improving the versatility of the filter element structure. It also effectively prevents filter media leakage. When adjacent spiral guide components are spliced, the feature points correspond to each other, and the multiple spiral blades form a spiral water flow channel, facilitating water flow. The protrusions effectively prevent filter media from adhering to the surface of the spiral blades and increase the vibration frequency of the filter media, allowing for more thorough contact between the filter media and water. This filter element structure, through its spiral flow channel design, ensures sufficient contact between water and filter media. The internal division of the filter media mesh component tube into multiple spaces allows for dispersed storage of the filter media, preventing accumulation and ensuring the overall purification effect of the entire filter element.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0023] like Figure 1-6As shown, this utility model is a novel scale-inhibiting filter element structure, including a tube body 1. An inlet end cap 2 is provided on one side of the tube body 1, and an outlet end cap 3 is provided on the side of the tube body 1 away from the inlet end cap 2. PP non-woven fabric is provided between the tube body 1 and the inlet end cap 2, and between the tube body 1 and the outlet end cap 3, effectively preventing filter media leakage. A filter cylinder 4 is provided inside the tube body 1 near the outlet end cap 3, and a filter element core 5 is provided inside the filter cylinder 4. The filter element core 5 can further filter the water that has already been filtered by the filter media. Multiple filter media mesh components 6 are provided inside the tube body 1, and multiple equally spaced filter media spiral guide components 7 are provided between adjacent filter media mesh components 6. The arrangement of multiple filter media mesh components 6 creates multiple regions inside the tube body 1, allowing different types of filter media to be placed in different regions during use, thus effectively improving the versatility of the filter element structure. Simultaneously, separating the filter media effectively prevents filter media accumulation.

[0024] The filter media spiral guide assembly 7 includes a first connecting pipe 71, a fixing plate 72 in the middle of the first connecting pipe 71, and four matrix-arranged spiral blades 73 on both sides of the fixing plate 72. The spiral directions of the spiral blades 73 on both sides of the fixing plate 72 are the same. The outer sides of the spiral blades 73 are fixedly connected to the fixing plate 72 through a support plate 74. The upper surface of the spiral blades 73 has multiple matrix-arranged protrusions 76. A second connecting pipe 77 is provided below the first connecting pipe 71. The second connecting pipe 77 can be inserted into the first connecting pipe 71. Through the mutual cooperation between the first connecting pipe 71 and the second connecting pipe 77, adjacent filter media spiral guide assemblies 7 are connected to each other. The spiral blades 73 on both sides of the fixing plate 72 have five feature points, namely A, B, C, D, and E. Figure 6 As shown, when adjacent spiral guide components 7 are spliced ​​together, points E and A overlap, and points B and D overlap. At this time, the multiple spiral blades 73 form a spiral water flow channel. The protrusions 76 can effectively prevent the filter media from adhering to the surface of the spiral blades 73, while increasing the jumping frequency of the filter media, so that the filter media can have more full contact with the water.

[0025] The filter media mesh assembly 6 includes an outer connecting ring 61, an inner connecting ring 62 in the middle of the outer connecting ring 61, and a fixing ring 63 between the outer connecting ring 61 and the inner connecting ring 62. Multiple ultrasonic lines 64 are arranged in a matrix between the outer connecting ring 61 and the fixing ring 63, and between the inner connecting ring 62 and the fixing ring 63. The ultrasonic lines 64 enable the filter media mesh assembly 6 to be welded to the PP non-woven fabric, thereby further preventing filter media leakage. A baffle 65 is provided between adjacent ultrasonic lines 64. Multiple equally spaced guide grooves 66 or waterproof sealant are provided on the baffle 65. The O-rings and waterproof sealant effectively increase the sealing between the inlet end cap 2 and the pipe body 1, and between the outlet end cap 3 and the pipe body 1.

[0026] The upper end of the spiral blade 73 is fixedly connected to the first connecting pipe 71 through the flat rib plate 75. The setting of the flat rib plate 75 makes the spiral blade 73 between the two filter material spiral guide assemblies 7 fit more closely.

[0027] The cross-section of the baffles 65 located on both sides of the fixed ring 63 is conical.

[0028] The outer surface of the spiral blade 73 is provided with an orange-textured surface. The orange-textured surface increases the friction that the spiral blade 73 avoids, thereby reducing the probability of filter material adhering to the surface of the spiral blade 73.

[0029] The filter element 5 is either a PPF filter or an activated carbon filter. PPF filters have excellent filtration precision, with standard models reaching a filtration standard of 1-5 microns. This precision is sufficient to intercept most impurities visible to the naked eye and can even effectively remove some tiny particles that are harmful to the human body. After filtration by a PPF filter, the clarity and cleanliness of the water can be significantly improved. Activated carbon has a highly developed pore structure and a huge specific surface area. The specific surface area of ​​each gram of activated carbon can reach hundreds or even thousands of square meters. It can adsorb a variety of pollutants in the water, as well as organic matter such as humic substances in the water, reducing the color and odor of the water.

[0030] O-rings or waterproof sealant are provided between the water inlet end cap 2 and the pipe body 1, and between the water outlet end cap 3 and the pipe body 1. The O-rings and waterproof sealant effectively increase the sealing between the water inlet end cap 2 and the pipe body 1, and between the water outlet end cap 3 and the pipe body 1.

[0031] The inlet end cap 2 and the pipe body 1, as well as the outlet end cap 3 and the pipe body 1, are sealed by spin welding or ultrasonic wave.

[0032] Specifically, in this utility model, the arrangement of multiple filter media mesh components 6 creates multiple regions inside the tube body 1. This allows different types of filter media to be placed in different regions during use, effectively improving the versatility of the filter media structure and preventing leakage. The second connecting pipe 77 can be inserted into the first connecting pipe 71. Through the cooperation between the first connecting pipe 71 and the second connecting pipe 77, adjacent filter media spiral guide components 7 are connected to each other. The spiral blades 73 on both sides of the fixed plate 72 have five feature points, namely A, B, C, D, and E. Figure 6 As shown, when adjacent spiral guide components 7 are spliced ​​together, points E and A overlap, and points B and D overlap. At this time, the multiple spiral blades 73 form a spiral water flow channel, which facilitates water flow. The protrusions 76 effectively prevent filter media from adhering to the surface of the spiral blades 73 and increase the vibration frequency of the filter media, allowing the filter media to have more sufficient contact with the water. The textured surface increases the friction of the spiral blades 73, thereby reducing the probability of filter media adhering to the surface of the spiral blades 73. The ultrasonic lines 64 allow the filter media mesh component 6 to be welded to the PP non-woven fabric, thereby further preventing filter media leakage.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
