Abstract
The invention discloses a filter element and a preparation method thereof. The preparation method comprises the following steps of: mixing and stirring raw materials, namely diatomite, kaolin, wooden powder, a bonding agent CMC (sodium carboxy methyl cellulose), water, carbon powder, straw ashes, phenolic resin, magnesium oxide and natural zeolite at a certain weight ratio; performing grouting molding or compaction molding on the mixture; and drying the molded mixture and sintering at the temperature of 900-1,300 DEG C, thus obtaining the filter element. The preparation method is simple, the formula is rational, the cost is low, and the prepared filter element is high in heat resistance and good in abrasion resistance.
Description
Technical field
The present invention relates to a kind of filter core and preparation method thereof, belong to manufacture field.
Background technology
As everyone knows, the filter opening of traditional filter core is all superfine micro-, and be high density and distribute, therefore for the higher area of water turbidity, as easy as rolling off a log round mud or iron rust etc. block compared with coarse granule impurity, and affect it, filter the water yield, therefore conventionally all arrange again together or have together the low-density filter core of larger filter opening before this high density filter core, utilize preposition filter core to remove in advance thicker thick impurity in water, mud, suspended material etc., so as to protecting rearmounted activated carbon cartridge, the high density filter cores such as ion exchange resin filter core or pellicle (R0) filter core, make its unlikely function such as the clean or absorption of its filter that affected compared with thick thick impurity coating.Its major defect is: conventional preposition filter core, it is nothing more than being to consist of materials such as PP plastic cement, fiber, knitting wool, therefore must abandon after blocking, cannot again rinse for reusing, not only expendable is large for it, causes manpower and materials burden, and owing to not meeting environmental protection condition, cannot complete at short notice decomposition, so that all become environment high pollution material in the future, not meet economic environmental requirement.
Summary of the invention
In order to solve shortcomings and deficiencies of the prior art, the object of the present invention is to provide a kind of filter core and preparation method thereof.Preparation method of the present invention is simple, and rationally, cost is low for formula, and the filter core that makes is heat-resisting, wearability good.
The present invention adopts following technical scheme to achieve these goals:
Filter core, is characterized in that the weight portion of its constitutive material is: have diatomite 35-40 part, kaolin 10-15 part, wood powder 6-9 part, adhesive C MC 6-8 part, water 40-50 part, carbon dust 10-15 part, stalk ashes 3-5 part, phenolic resins 20-30 part, magnesia 10-15 part and natural zeolite 10-15 part.
The preparation method of described filter core, is characterized in that: by the weight portion of constitutive material, take each constitutive material, mix and blend, by injection forming or pressed compact moulding, 900-1300 ℃ of calcining, obtains this filter core after being dried.
Beneficial effect of the present invention:
Preparation method of the present invention is simple, and rationally, cost is low for formula, and the filter core that makes is heat-resisting, wearability good.
The specific embodiment

The preparation method of filter core, takes each constitutive material by the weight portion of constitutive material, and mix and blend, by injection forming or pressed compact moulding, 900-1300 ℃ of calcining, obtains this filter core after being dried.
The Static Water adsorbance 16.4% of obtained filter core; Compression strength 4587N; Compatibility 0.01%.
embodiment 2:filter core, the weight portion of its constitutive material is: have 12 parts of 37 parts, diatomite, 12 parts of kaolin, 8 parts of wood powders, 7 parts of adhesive C MC, 45 parts, water, 12 parts of carbon dusts, 4 parts, stalk ashes, 25 parts, phenolic resins, 12 parts, magnesia and natural zeolites.
The preparation method of filter core, takes each constitutive material by the weight portion of constitutive material, and mix and blend, by injection forming or pressed compact moulding, 900-1300 ℃ of calcining, obtains this filter core after being dried.
The Static Water adsorbance 17.5% of obtained filter core; Compression strength 4875N; Compatibility 0.0085%.
embodiment 3:filter core, the weight portion of its constitutive material is: have 15 parts of 40 parts, diatomite, 15 parts of kaolin, 9 parts of wood powders, 8 parts of adhesive C MC, 50 parts, water, 15 parts of carbon dusts, 5 parts, stalk ashes, 30 parts, phenolic resins, 15 parts, magnesia and natural zeolites.
The preparation method of filter core, takes each constitutive material by the weight portion of constitutive material, and mix and blend, by injection forming or pressed compact moulding, 900-1300 ℃ of calcining, obtains this filter core after being dried.
The Static Water adsorbance 16.8% of obtained filter core; Compression strength 4967N; Compatibility 0.0087%.
