Abstract
The invention provides a preparation method of a diatomite water quality purifying agent. The preparation method includes the steps: drying diatomite in the sun or oven-drying the diatomite to make the moisture content below P10, and thus obtaining blocky diatomite; mixing the blocky diatomite with an auxiliary agent to obtain a mixture; and smashing the mixture to obtain the diatomite water quality purifying agent, wherein the temperature is 100-200 DEG C, and the rotating speed is 2400 r/min or more. The raw materials are mixed at the temperature of 100-200 DEG C and the speed of 2400 r/min or more, with high-speed running and mixing with temperatures, the prepared diatomite is mixed uniform, chemical raw materials modified by poly-aluminum and other matters are totally absorbed by cross-linked pores of the diatomite, no poly-aluminum and diatomite splitting phenomenon exists, the modification effect is good, the speed is fast, the yield is high, the quality is good, the labor force is greatly reduced, and the present product cost is reduced.
Description
Technical field
The present invention relates to the preparing technical field of water quality cleansing agent, refer to especially a kind of preparation method of diatomite water quality cleansing agent.
Background technology
Diatomite is that the diatoms remains of growing in ocean or lake are at subaqueous deposit, through physical environment effect and the biogenesis silicastone forming gradually.Its mineral composition is non-crystalline state opal.In the surface and micropore thereof of diatom test, there are a large amount of carboxyls to cover, and have hydrogen bond to exist, thereby aobvious slightly acidic, therefore be also referred to as solid acid.On diatomite housing, micropore is intensive, bulk density is little, specific surface area is large, thereby has stronger adsorptive power and strainability.Therefore, diatomite is always in aspect widespread uses such as organic chemical industry's synthesis catalytic agent carrier, flocculating aids, sewage disposal, light building materials.Diatomite is usually used in the processing of the waste water such as tap water, swimming-pool water, process water, boiler recirculated water at present.
Conventionally the diatomite sewage-treating agent of modification is to mix with artificial at present, and shortcoming is that labour cost is large, inhomogeneous, and the quality of mixing is unstable.The industrial chemicals of poly-aluminium and ferro-aluminum, mixes less than diatomite and hands over the inside, hole, is just bonded in surface; Even attachedly do not enter diatomite surface, each spontaneous fission, do not have effect.The employing machine modification of heating, admittedly poly-aluminium, flow sour aluminium, run into while lacking a class Chemicals modification 50 degree temperature above will melt produce water liquid also cannot modification.So can only adopt at present manual modification, its poor quality does not reach that modified effect, its consumption are large, high in cost of production shortcoming.
Summary of the invention
The present invention proposes a kind of preparation method of diatomite water quality cleansing agent, has solved the industrial chemicals such as poly-aluminium and ferro-aluminum in prior art and has mixed the technical problem of handing over the inside, hole, each spontaneous fission less than diatomite.
