Columnar particle diatomite production formula and forming process thereof
The invention relates to the technical field of diatomite production and manufacturing, and discloses a production formula of columnar particle diatomite, which comprises the following raw materials by weight: 55-65 parts of modified diatomite; 1.5 to 10.5 parts of an adhesive; and 23-38 parts of a pore-foaming agent. The invention relates to a molding process of columnar particle diatomite. The molding process comprises the following steps: S1, preparing modified diatomite; s2, weighing the raw materials; step S3: feeding and stirring; step S4: granulating and drying; s5, roasting: putting the columnar particle diatomite prepared in the step S4 into a rotary kiln, and roasting at the roasting temperature of 800-900 DEG C for 10-30 minutes; and step S6: screening. By improving the formula proportion and the forming process of diatomite and performing columnar granulation, the adsorption rate of methylene blue can be further improved, and the problem that the existing catalyst or adsorbent has a relatively poor adsorption effect on methylene blue is solved.
本发明涉及硅藻土生产制造技术领域，公开一种柱状颗粒硅藻土生产配方，包括以下重量份原料：改性硅藻土55～65份；胶黏剂1.5～10.5份；致孔剂23～38份。一种柱状颗粒硅藻土的成型工艺，包括以下步骤：步骤S1：制备改性硅藻土；步骤S2：原材料称量；步骤S3：进料、搅拌；步骤S4：造粒、干燥；步骤S5：焙烧，将步骤S4制得的柱状颗粒硅藻土放入回转窑中进行焙烧，焙烧温度为800～900度，焙烧时间为10～30min；步骤S6：筛选。通过对硅藻土配方比例及成型工艺进行改进并进行柱状制粒，可进一步提高对亚甲基蓝的吸附率，解决了现有催化剂或吸附剂对亚甲基蓝吸附效果相对较差的问题。
