Description

Technical Field

[0001] This invention relates to the field of aquarium water treatment technology, specifically a negative ion manganese sand black and white sphere filter media. Background Technology

[0002] Aquarium filtration systems are the core component for maintaining water quality stability and the health of aquatic organisms, and their performance directly depends on the functionality of the filter media. Currently, mainstream filter media on the market (such as ceramic rings, bio-balls, activated carbon, quartz sand, and maifanite) generally have the following shortcomings:

[0003] 1. Limited Functionality: Various filter materials focus on only a single function (such as physical interception, biological cultivation, or adsorption of specific ions), making it difficult to simultaneously achieve multiple purification needs such as heavy metal oxidation and removal, negative ion release, microenvironment regulation, and antibacterial properties.

[0004] 2. Low space efficiency: In order to achieve the overall effect, users need to stack multiple filter media, resulting in excessive space occupancy in the filter chamber, obstructing the water flow channel and reducing filtration efficiency.

[0005] 3. Complex maintenance: The design of mixing or layering multiple types of filter media can easily lead to confusion or omissions during cleaning or replacement, increasing the operational burden.

[0006] 4. Lack of synergistic effect: Existing filter media combinations are mostly simple stacking, lacking physical and chemical synergistic mechanisms between functional units, and even interfering with each other (such as activated carbon adsorption interfering with the release of mineral ions), thus failing to form a synergistic effect.

[0007] Especially for the deep purification of heavy metal ions (such as iron and manganese), traditional manganese sand filter media, while possessing oxidation and adsorption capabilities, cannot simultaneously optimize the microenvironment of the water; while negative ion materials, although capable of activating the water body, have no direct removal effect on heavy metal pollution. These contradictions result in long water purification cycles, poor stability, and frequent water changes still cannot prevent the frequent occurrence of aquatic organism diseases.

[0008] Therefore, there is an urgent need to develop a composite filter material with integrated structure and synergistic function to break through the existing technological bottlenecks and achieve a leap in water purification efficiency in multiple dimensions within a limited space. Summary of the Invention

[0009] The technical problem to be solved by this invention is: how to simultaneously achieve efficient oxidation and removal of heavy metals and activation of negative ion water quality within the limited filtration space of an aquarium, overcoming the defects of traditional multi-filter media combinations such as large space occupation, functional fragmentation, and insufficient synergy.

[0010] The technical solution adopted in this invention is as follows: a negative ion manganese sand black and white sphere filter material, which is composed of two functional units, black manganese sand spheres and white negative ion spheres, physically mixed or layered and stacked; the black manganese sand spheres are mainly composed of manganese dioxide and are in the form of porous spherical particles; the white negative ion spheres are made of natural mineral materials that can release negative ions, are in the form of porous spherical particles, and are configured to release negative ions at a rate of 50 to 30,000 ions / cm³. 3 .

[0011] As a further aspect of the present invention: when the two functional units are physically mixed, the volume mixing ratio of the black manganese sand ball and the white negative ion ball is 1:3 to 3:1.

[0012] As a further aspect of the present invention: when the two functional units are stacked in layers, the structure includes a filter layer mainly composed of black manganese sand balls and a filter layer mainly composed of white negative ion balls.

[0013] As a further aspect of the present invention: a water-permeable mesh is provided between the black manganese sand ball filter layer and the white negative ion ball filter layer.

[0014] As a further aspect of the present invention, the diameter of the black manganese sand ball is 5-100mm.

[0015] As a further aspect of the present invention, the diameter of the white negative ion ball is 5-100 mm.

[0016] As a further aspect of the present invention, the average particle size of the white negative ion ball is larger than the average particle size of the black manganese sand ball.

[0017] As a further aspect of the present invention: the natural mineral material of the white negative ion ball is selected from the group including tourmaline, zirconia, opal, quartz, kaolin, raw ore, high white porcelain, ceramic clay, and ceramic spherical particles of 0.2-3 mm.

[0018] As a further aspect of the present invention: both the black manganese sand balls and the white negative ion balls have mechanical strength and water resistance, and are not easily pulverized after long-term immersion.

[0019] As a further aspect of the present invention: the white negative ion ball releases negative ions in the range of 50-30000 ions / cm². 3 .

[0020] The beneficial effects of this invention are:

[0021] 1. Functional integration and synergistic effects:

[0022] Manganese sand balls efficiently remove Fe from water through their porous structure and strong oxidizing properties (MnO2). 2+ Mn 2+It also adsorbs heavy metal ions (such as lead, copper, and arsenic) and precipitates, while providing an interface for nitrifying bacteria to attach.

[0023] The negative ion ball continuously releases negative ions (50-30,000 ions / cm³). 3 It also contains far-infrared rays, which neutralize the charge of colloidal pollutants, activate water molecules, and inhibit the growth of harmful bacteria.

[0024] Synergistic mechanism: Manganese sand balls preferentially oxidize and remove heavy metals, reduce water turbidity, create a low-interference environment for negative ion balls, and improve negative ion release efficiency; negative ion balls optimize the water microenvironment (such as increasing ORP value), and feed back into the microbial activity on the surface of manganese sand balls, achieving a triple cycle of "oxidation adsorption-ion activation-biological purification" for enhanced efficiency.

[0025] 2. Space utilization rate doubled:

[0026] By physically mixing (volume ratio 1:3 to 3:1) or compact layered stacking (with permeable mesh between layers), dual functions are integrated into a single filter media unit, saving more than 30% of filter chamber space compared to traditional multi-filter media combinations, and optimizing water flow distribution and flux.

[0027] 3. Water purification efficiency has been greatly improved:

[0028] Actual Fe measurement 2+ / Mn 2+ Removal rate > 90% (data from document 3, example), negative ion concentration stable at 50-30000 ions / cm³ 3 ;

[0029] The oxidation-reduction potential (ORP) increases by 50-150mV, significantly enhancing the water's self-purification ability;

[0030] The incidence of aquatic organism diseases has been reduced by more than 40%, and the water exchange cycle has been extended by 50%.

[0031] 4. Long-term stability and ease of maintenance:

[0032] The spheres possess high mechanical strength and water resistance (they do not pulverize after long-term immersion) and have a lifespan of ≥2 years.

[0033] Mixed states allow for direct batch replacement, while the layered structure enables layered maintenance through a mesh screen, improving operational efficiency by 60%.

[0034] 5. Wide application compatibility:

[0035] It is compatible with freshwater / seawater systems and supports all types of aquarium filtration and aquaculture equipment, including top filters, bottom filters, and canister filters. Attached Figure Description

[0036] Figure 1 This is a schematic diagram of the overall structure of a negative ion manganese sand black and white sphere filter material according to the present invention. Detailed Implementation

[0037] The present invention will be further described below.

[0038] This filter media consists of black manganese sand balls (mainly composed of MnO2) and white negative ion balls (natural minerals that release negative ions), and can be combined in any of the following ways:

[0039] (1) Physical mixing: The two balls are mixed evenly;

[0040] (2) Layered stacking: Manganese sand ball layer and negative ion ball layer are stacked one on top of the other, with a water-permeable mesh (such as nylon mesh, pore size 1-2mm) between the layers.

[0041] Example 1: Physically Hybrid Filter Media

[0042] 1. Raw material preparation:

[0043] Black manganese sand balls: Manganese dioxide (10%), quartz sand (65%), and kaolin (25%) are granulated and sintered into porous spherical particles with a particle size of 3-10 mm, a porosity of 40-60%, and a water immersion resistance strength of >10 N / particle.

[0044] White negative ion balls: Mix tourmaline powder (50%), opal powder (30%), and ceramic binder (20%), granulate, and sinter into porous spherical particles with a particle size of 5-15mm and a negative ion release of 50-30,000 ions / cm³. 3 .

[0045] 2. Mixing ratio: Add the two types of spheres into the mixer at a volume ratio of 1:1 and mix for 10 minutes until homogeneous.

[0046] 3. Application Scenarios: Fill the biological chamber of the filter cartridge, occupying 70% of the chamber volume. Water flows vertically through the mixing layer, and manganese sand balls oxidize and adsorb Fe. 2+ / Mn 2+ (Measured removal rate 92%), negative ion balls simultaneously increase ORP value by +120mV.

[0047] Example 2: Layered Stacked Filter Media

[0048] 1. Hierarchical structure (bottom to top):

[0049] Bottom layer: Black manganese sand spheres, 5cm thick, 4-6mm in diameter;

[0050] Interlayer: Polypropylene permeable mesh (pore size 1.5mm, open area ≥90%);

[0051] Upper layer: White negative ion spheres, 8cm thick, 10-14mm in diameter.

[0052] Note: The water flow direction can be from bottom to top (manganese sand first, then negative ions) or in the opposite direction.

[0053] 2. Key parameters:

[0054] The porosity of manganese sand spheres is 35-50%, and the porosity of negative ion spheres is 45-65%.

[0055] The raw materials for the negative ion balls have been replaced with a mixture of kaolin and icy stone, releasing 1800 negative ions per cm³. 3 .

[0056] 3. Effect Verification: Used in the bottom filter of a seawater aquarium, Mn 2+ Removal rate 88%, negative ion concentration maintained at ≥1000 ions / cm³ 3 The coral bleaching rate decreased by 40%.

[0057] Example 3: Variant Implementation

[0058] 1. Replacement of negative ion ball material:

[0059] Option A: Quartz-based negative ion balls (particle size 6-10mm, negative ion quantity 300-5000 ions / cm³) 3 );

[0060] Option B: Sintering of ceramic spherical particles (0.3mm) mixed with high-white porcelain powder, particle size 12-15mm, negative ion content 2500 ions / cm³ 3 .

[0061] 2. Mixing ratio expansion: Manganese sand balls: negative ion balls = 1:3 (focusing on negative ion release) or 3:1 (focusing on heavy metal removal).

[0062] 3. Particle size matching rules:

[0063] When used in combination, the average particle size of the negative ion balls should be ≥ the particle size of the manganese sand balls + 2mm (e.g., 6mm manganese sand balls → 8mm negative ion balls) to avoid small-diameter manganese sand clogging the pores of the large balls.

[0064] Example 4: Comparison Experiment with Existing Filter Media

[0065] 1. Experimental setup

[0066] Test subject: 200L freshwater aquarium, initial water quality: Fe 2+ =0.8 mg / L, Mn 2+ =0.5mg / L, ORP=150mV, nitrifying bacteria colony count=10 3 CFU / mL.

[0067] Filtration system: bottom filter chamber (effective volume 20L), water flow rate 0.5L / min.

[0068] Control group filter media regimen (each group had 15L of filter media):

[0069] Group Filter media composition Fill method Control group A Activated carbon layer (5L) + ceramic ring (10L) Layered stacking Control group B Quartz sand (8L) + Maifan stone (7L) Physical mixing Control group C Single manganese sand balls (15L, particle size 5-8mm) Single-layer fill This invention group Manganese sand balls (7.5L) + Negative ion balls (7.5L) Physical mixing (1:1)

[0072]

[0073] 3. Defect Analysis and Advantages of the Invention

[0074] (1) Single function:

[0075] Control group A (activated carbon + ceramic rings): Activated carbon only adsorbs organic matter, but cannot remove Mn. 2+ (Removal rate 52%); ceramic ring culture bacteria but no heavy metal purification ability.

[0076] This invention integrates multiple functions: manganese sand balls simultaneously remove heavy metals (>90%), and negative ion balls activate the water.

[0077] (2) Low space efficiency:

[0078] Control group B (quartz sand + maifan stone): Requires a 15L mixing and filling to achieve basic filtration, but Mn 2+ The removal rate was only 38%.

[0079] This invention offers dual-function synergy within the same volume, saving 30% of space (compared to traditional multi-filter media combinations).

[0080] (3) Lack of synergistic effect:

[0081] Control group C (single manganese sand ball): Although 85% of Fe was removed 2+ However, the ORP was only +40mV, which was insufficient to suppress the pathogen (disease rate 15%).

[0082] This invention: Negative ions increase ORP to +135mV, significantly enhancing the antibacterial effect (reducing the disease rate to 5%), while simultaneously promoting the proliferation of bacterial colonies on the surface of manganese sand balls by 10 times.

[0083] (4) Maintenance complexity:

[0084] The control group A / B requires sorting different filter media (maintenance > 40 minutes), which is easy to miss; the mixed filter media of this invention can be directly replaced in batches, improving efficiency by 60%.

[0085] 4. Conclusion

[0086] (1) Functional Breakthrough: This invention solves the problem of functional fragmentation in traditional filter media through the synergistic mechanism of manganese sand ball oxidation adsorption + negative ion ball activation (such as ORP increasing to 285mV), achieving a heavy metal removal rate of >90% and a negative ion concentration of >2000 ions / cm³. 3 .

[0087] (2) Space optimization: The physical hybrid design increases the utilization rate of the filter chamber by 30% and avoids the flow resistance problem caused by multi-layer stacking.

[0088] (3) Long-term economic benefits: The filter material has a lifespan of ≥2 years (the activated carbon in the control group needs to be replaced every month), and the overall operation and maintenance costs are reduced by 50%.

[0089] (4) Biosafety: The disease rate was reduced to 5% (the average rate of the control group was 22%), verifying the reliability of the “oxidation-activation-inhibition” cycle.

[0090] in conclusion

[0091] Based on the implementation verification of Examples 1 to 4, the core implementation points and technical advantages of the present invention are summarized as follows:

[0092] 1. Completeness of the technical solution:

[0093] The filter material achieves multifunctional integration through two standardized configurations: physical mixing (Example 1) and layered stacking (Example 2), covering the entire scope of the claims;

[0094] The permeable mesh design (1-2mm aperture) is an essential technical feature of the layered structure, solving the problems of cross-contamination and maintenance of functional layers (compared to the solution without mesh, maintenance efficiency is improved by 60%).

[0095] 2. Clear parameter boundaries:

[0096] Core parameters Scope of Implementation Technological effect Manganese sand ball particle size 3-10mm (5-8mm preferred) Ensure oxidation contact area and water flow rate negative ion sphere particle size 5-15mm (preferably 8-12mm) Matching the pore size requirements for negative ion release Particle size gradient rule White ball diameter ≥ Black ball + 2mm Avoid mixed blockages (verified in Example 3) negative ion release <![CDATA[50 - 30,000 per cm 3 > Balancing activation efficiency with material costs

[0097] 3. Universality of synergistic effects:

[0098] The dual-function coupling mechanism holds true in all embodiments:

[0099] Manganese sand balls remove heavy metals (Fe) 2+ / Mn 2+ Removal rate > 85% → Reduces water turbidity → Increases negative ion release efficiency by 15-30% (compared to single use);

[0100] Negative ions activate water quality (ORP increases by 50-150mV) → promote the activity of nitrifying bacteria on the surface of manganese sand balls (biofilm density increases by 40%).

[0101] This mechanism is independent of the material composition (tourmaline / quartz / ceramics, etc.) (verified by the variant of Example 3).

[0102] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
