(2) the above-mentioned raw material be uniformly mixed is transferred to tablets press, opens tablets press and carry out granulation;
(3) raw material granulation completed adds in forming machine, by forming machine, the embryonic type of ceramic element is carried out to extrusion moulding, the embryonic type of moulding is blocked and is put on shelf and dry;
(4) above-mentioned embryonic type of drying being moved into to baking oven is toasted;
(5) embryonic type of above-mentioned baking being put into to High Temperature Furnaces Heating Apparatus fires;
(6) the above-mentioned product of having fired is cut into after desired size to polishing again and remove powder, obtain described diatomite ceramic element.
As improvement, above-mentioned steps (4) is to toast and complete in 1 day under 70～90 ℃, and preferably temperature is 80 ℃.
Improve again, above-mentioned steps (5) is specially: the embryonic type of above-mentioned baking is put into to High Temperature Furnaces Heating Apparatus, heat up with the speed of 70～75 ℃/h, be incubated 2h after being warming up to 1100～1200 ℃, then with the speed cooling of 130～140 ℃/h, after temperature is down to 80 ℃, product is shifted out to High Temperature Furnaces Heating Apparatus.
As preferably, in described step (1), the mass ratio of each component is diatomite 95%, the expanding agent 2% of fluxing, sizing agent 2.5%, idiosome toughener 0.5%.
The main component water glass of the described expanding agent of fluxing, described sizing agent adopts treated starch to dissolve 10 times in its water, adds 0.5% sodium hydroxide modulation to form, and the main component of described idiosome toughener is calcium oxide.
Compared with prior art, the invention has the advantages that: in the diatomite ceramic element of making through method provided by the invention, do not contain other mineral substance, avoided the infringement of harmful chemical element to human body, can guarantee that the filtering accuracy of diatomite ceramic element, between 0.15 μ m～0.5 μ m, can reach filter effect preferably; And, diatomite ceramic element preparation method of the present invention adopts extrusion moulding, avoided making the trouble that the different shapes model brings, being conducive to manufacturer enhances productivity, and the calcining institute spended time of step in this preparation method (5) is shorter, within general about one day, just can complete, further improve the competitiveness of product in market.
