Embodiment 1
[0046] Embodiment 1: Preparation of microcrystalline bamboo charcoal purple sand composite ceramsite filter material
[0047] The percentage by weight of raw materials is: 20-30% of microcrystalline bamboo charcoal, 40-55% of purple sand raw material, 10-30% of attapulgite, 5-30% of diatomite and 1-5% of binder.
[0048] Mix the proportions according to the proportion, after mixing by the mixer, add water to granulate in the granulator to form spherical particles with a particle size of 1-10mm, then dry the granules, and then put them into the sintering furnace for anaerobic sintering, and finally sintering The temperature is 800-1150°C, and the product can be obtained after cooling. For the preparation method, see figure 1 , the main properties are shown in Table 5.

Embodiment 2
[0052] Embodiment 2: Preparation of microcrystalline bamboo charcoal purple sand composite pottery tea set and rice cooker
[0053] The weight percentages of the raw materials are: 10-20% microcrystalline bamboo charcoal, 40-60% purple sand, 5-10% attapulgite, 2-5% diatomite, and 5% binder.
[0054] Grind microcrystalline bamboo charcoal, purple sand raw materials, attapulgite, and diatomaceous earth to a size below 200 meshes, mix them in proportion, add water to make the mud, and age it for several days (the degree of mud refining and the aging time depend on meeting the molding conditions), so that The water content of the mud mud is uniformly associated, and the mud material is added to the spinning machine for spinning and forming; after forming, it is air-dried first, and then put into a sintering furnace for anaerobic sintering. The final sintering temperature is 800-1150°C, and finally cooled to obtain the product. For the preparation method, see figure 2 , the main ...
Embodiment 3
[0058] Embodiment 3: the preparation of microcrystalline bamboo charcoal purple sand composite honeycomb or porous pottery
[0059] The weight percentages of the raw materials are: 20-30% microcrystalline bamboo charcoal, 30-45% purple sand, 5-15% attapulgite, about 5% diatomite, and about 5% binder.
[0060] Grind microcrystalline bamboo charcoal, purple sand raw materials, attapulgite, and diatomaceous earth, and mix them according to the proportion below 200 meshes. Put it into a forming abrasive tool and extrude it; after forming, let it dry naturally; then put it into a sintering furnace for anaerobic sintering, the final sintering temperature is 800-1150°C, and finally cool down to get the product. For the preparation method, see image 3 , the main performance indicators are shown in Table 7.
