Abstract
The invention belongs to the field of dryers, and particularly relates to an attapulgite desiccant. The attapulgite desiccant is prepared from the following raw materials in parts by weight: 55-65 parts of attapulgite, 12-20 parts of calcium carbonate, 25-30 parts of silicon dioxide and 15-18 parts of aluminum oxide by the processes of calcining, crushing, pelleting and then calcining. Clay is used as a main raw material, the attapulgite desiccant is wide in raw material source, simple in preparation technology, free of pollution, and large in gaps among molecules of attapulgite, and has a good adsorption effect, and the desiccant disclosed by the invention is dried at 250-320 DEG C after being used, and then can be repeatedly used, so that waste is reduced.
Description
Technical field
The invention belongs to drier field, be specifically related to a kind of preparation method of attapulgite drier.
Background technology
Drier is used very extensive in food industry and chemical engineering industry, but the drier that is mostly chemical synthesis using at present, drier often has certain toxicity, and preparation method is complicated, in preparation process, intermediate product is difficult for processing, after using, drier can produce pollution, be difficult for processing, and drier can not be reused, caused very large waste, and in drier preparation process, need to use a large amount of chemicals, cost is higher.
Summary of the invention
For solving the above-mentioned shortcoming of prior art, the invention provides a kind of attapulgite drier, preparation method is simple, can reuse.
The present invention is achieved through the following technical solutions:
A preparation method for attapulgite drier, is characterized in that comprising the following steps:
(1), by attapulgite in situation weathering 1-2 month in the open;
(2), attapulgite 100kg put into pond with clear water, wash, remove after foreign matter, Xiang Chizhong adds calcium carbonate 10kg, silica 8kg, aluminium oxide 5kg, is uniformly mixed, and then with tablet press machine, carries out compressing tablet;
(3), mixture that above-mentioned steps is handled well dries at 300 ℃, uses lapping device to be ground into 360 object powder;
(4), above-mentioned powder is calcined to 3h at 600 ℃, after taking-up, with comminutor, carry out granulation, particle diameter is 2-3mm;
(5), above-mentioned particle is dried at 260 ℃ to water content and is less than 10%, then add kiln to calcine 1h at 550 ℃, naturally cooling, packing, makes finished product.
Beneficial effect of the present invention: the present invention uses clay as primary raw material, raw material sources are extensive, and preparation technology is simple, pollution-free, the intermolecular space of concave convex rod is larger, be equipped with aluminium oxide and silica, the water absorbing capacity of drier is obviously promoted, drier of the present invention is after use, after dry at 250-320 ℃, can reuse, save the energy, reduce waste.
The specific embodiment
A preparation method for attapulgite drier, is characterized in that comprising the following steps:
(1), by attapulgite in situation weathering 1-2 month in the open;
(2), attapulgite 100kg put into pond with clear water, wash, remove after foreign matter, Xiang Chizhong adds calcium carbonate 10kg, silica 8kg, aluminium oxide 5kg, is uniformly mixed, and then with tablet press machine, carries out compressing tablet;
(3), mixture that above-mentioned steps is handled well dries at 300 ℃, uses lapping device to be ground into 360 object powder;
(4), above-mentioned powder is calcined to 3h at 600 ℃, after taking-up, with comminutor, carry out granulation, particle diameter is 2-3mm;
(5), above-mentioned particle is dried at 260 ℃ to water content and is less than 10%, then add kiln to calcine 1h at 550 ℃, naturally cooling, packing, makes finished product.
