Coal gangue ceramsite and preparation method thereof
The invention discloses coal gangue ceramsite and a preparation method thereof. The coal gangue ceramsite comprises coal gangue, glass powder, calcium oxide, carbon mud and a foaming agent. The preparation method comprises steps: taking the coal gangue, the glass powder, the calcium oxide, the carbon mud and the foaming agent in parts by weight: 70: 5: 5: 15: 5, grinding coal gangue and calcium chloride into powder; fully mixing coal gangue and calcium chloride powder by using a high-speed stirrer; adding water of which the weight is equal to the total weight of the coal gangue and calcium chloride powder after mixing; then adding the foaming agent, stirring, preparing a mixture into spherical particles; drying by using a constant-temperature heating box, spraying hot alkaline water for 10minutes after cooling, drying again after spraying is finished, grinding the glass powder and the carbon mud into a powder with the particle size of less than 1mm by using a spherical grinding machine, adding an equal amount of water, stirring by using a high-speed stirrer, coating the outer sides of spherical particles with a mixture after stirring is finished, and drying. The coal gangue ceramsite can be continuously and effectively used for sewage purification and is good in purification effect and high in durability.
本发明公开了一种煤矸石陶粒及其制备方法，包括煤矸石、玻璃粉、氧化钙、炭泥和发泡剂，所述煤矸石、玻璃粉、氧化钙、炭泥和发泡剂的重量份数配比为:70：5：5：15：5，将煤矸石和氯化钙研磨至粉状，使用高速搅拌机将煤矸石和氯化钙的粉状物充分混合在一起，混合后加入和煤矸石及氯化钙粉体总重量相等的水，然后加入发泡剂，进行搅拌，将混合料制成球状颗粒，使用恒温加热箱烘干，冷却后使用热碱水喷洒10分钟，喷洒完成后再次烘干，将玻璃粉和炭泥经过球形研磨机研磨至粒径小于1mm的粉状，加入等量的水，使用高速搅拌机进行搅拌，搅拌完成后将混合物涂覆在球状颗粒外侧并烘干。本发明能够持续有效用于污水净化，净化效果好，持久性强。
