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 the manufacturing field.
Background technology
As everyone knows; The filter opening of traditional filter core is all superfine little; 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 than coarse granule impurity; Filter the water yield and influence it; So the low-density filter core that has big filter opening together or together all is set in the front of this high density filter core usually again; Utilize preposition filter core to remove thicker thick impurity in the water in advance; Mud; Suspended material etc.; So as to protecting rearmounted activated carbon cartridge; High density filter cores such as ion exchange resin filter core or pellicle (R0) filter core make the thick impurity lining of thicker of its unlikely quilt and influence function such as the clean or absorption of its filter.Its major defect is: preposition filter core commonly used; It is nothing more than being to be made up of materials such as PP plastic cement, fiber, knitting wool; So after blocking, promptly must abandon; Can't wash once more for repeated use, not only expendable is big for it, causes the manpower and materials burden; And owing to do not meet environmental protection condition; Can't accomplish decomposition at short notice, so that all become environment high pollution material, not meet economic environmental requirement in the future.
Summary of the invention
Deficiency and defective in order to solve 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 prescription is reasonable, and cost is low, 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: 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 are arranged.
The preparation method of described filter core is characterized in that: the weight portion by constitutive material takes by weighing each constitutive material, mixes and stirs after injection forming or pressed compact moulding 900-1300 ℃ of calcining, promptly get this filter core after the drying.
Beneficial effect of the present invention:
Preparation method of the present invention is simple, and prescription is reasonable, and cost is low, and the filter core that makes is heat-resisting, wearability good.
The specific embodiment

The preparation method of filter core takes by weighing each constitutive material by the weight portion of constitutive material, mixes and stirs after injection forming or pressed compact moulding, and dry back promptly gets this filter core 900-1300 ℃ of calcining.
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: 12 parts of 37 parts in diatomite, 12 parts of kaolin, 8 parts of wood powders, 7 parts of adhesive C MC, 45 parts in water, 12 parts of carbon dusts, 4 parts in stalk ashes, 25 parts in phenolic resins, 12 parts in magnesia and natural zeolites are arranged.
The preparation method of filter core takes by weighing each constitutive material by the weight portion of constitutive material, mixes and stirs after injection forming or pressed compact moulding, and dry back promptly gets this filter core 900-1300 ℃ of calcining.
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: 15 parts of 40 parts in diatomite, 15 parts of kaolin, 9 parts of wood powders, 8 parts of adhesive C MC, 50 parts in water, 15 parts of carbon dusts, 5 parts in stalk ashes, 30 parts in phenolic resins, 15 parts in magnesia and natural zeolites are arranged.
The preparation method of filter core takes by weighing each constitutive material by the weight portion of constitutive material, mixes and stirs after injection forming or pressed compact moulding, and dry back promptly gets this filter core 900-1300 ℃ of calcining.
The Static Water adsorbance 16.8% of obtained filter core; Compression strength 4967N; Compatibility 0.0087%.
