Problems solved by technology

[0004] At present, the activated carbon application technology lacks the application technology of activated carbon with corresponding materials for different adsorption objects.
In particular, there is a lack of activated carbon that can ensure that activated carbon has a good function of absorbing dirt, and can also purify and deodorize the odor generated when fresh objects such as toilets, livestock, and fish are corrupted.

Embodiment 1

[0027] Embodiment 1: The weight ratio of the raw materials used is: 40 parts of chemical activated carbon, 32 parts of coal-based granular activated carbon, 46 parts of coconut shell activated carbon; three kinds of activated carbons with different proportions are put into a ball mill for ball milling, and ground into The mesh number is 500 mesh activated carbon powder. Get 118 parts of activated carbon powders, 13 parts of bamboo vinegar, 2.5 parts of methylcellulose, and 2.5 parts of talcum powder that are ground into again. Add the above-mentioned raw materials into the mixer in turn, stir and mix evenly to make a mixture. Then put the mixture in a kneader (or mixer), add moderate distilled water, knead for 30 minutes, and knead it into a mud paste in the kneader. Then the mud paste is placed in a vacuum mud mill, and mud is honed into a uniform plasticized mud paste in the vacuum mud mill. Then put the plasticized mud paste in the extrusion molding, and extrude and proce...

Embodiment 2

[0029] Embodiment 2: The weight ratio of the raw materials used is: 36 parts of chemical activated carbon, 30 parts of coal-based granular activated carbon, 44 parts of coconut shell activated carbon, three kinds of activated carbons with different proportions are put into a ball mill for ball milling, and ground into The mesh number is 500 mesh activated carbon powder. Get ground activated carbon powder, 14 parts of bamboo vinegar, 3 parts of methyl cellulose, and 3 parts of talcum powder. The above-mentioned raw materials are sequentially added to stirring and mixing, stirring evenly to make a mixture. The remaining steps are the same as in Example 1, wherein the profile with a moisture content of less than 10% is placed in a furnace for sintering at 850° C. for 8 hours.

Abstract

The invention belongs to a bamboo vinegar honeycomb type purifying activated carbon and a preparation method thereof. The bamboo vinegar honeycomb type purifying activated carbon comprises, by weight, 35-40 parts of chemical activated carbon, 25-35 parts of granular activated carbon from coal, 43-49 parts of coconut shell activated carbon, 9-15 parts of bamboo vinegar, 2-3 parts of methyl cellulose and 2-3 parts of talcum powder. The preparation method includes ball grinding, well mixing raw materials, producing product materials, and subjecting the product materials to vacuum pugging, extrusion forming, drying and sintering. The bamboo vinegar honeycomb type purifying activated carbon is good in dirt absorption capability, firm in shaping durable, simple and practical in preparation method, low in sewage treating cost, low-carbon, energy saving, and good in treating effect, and corruption odor generated by toilets, livestock, fish and the like can be purified.
