Description

Technical Field

[0001] The utility model belongs to the technical field of ceramsite production equipment, and specifically relates to a multi-solid waste unburned ceramsite production system. Background Art

[0002] With the continuous advancement of industrialization, the amount of solid waste (referred to as "solid waste") generated and accumulated is increasing. Gold tailings are the product of gold ore beneficiation. Although the problem of tailings treatment has long been in the public eye, the amount of treatment is far less than the amount of accumulation. The accumulation of a large amount of tailings not only wastes resources, but also pollutes the environment.

[0003] Urban sewage is the product of human's necessary production and life. With the deepening of urbanization, the output of sewage is increasing rapidly. After sewage treatment plants treat it, a large amount of sludge will be produced. This sludge cannot be treated in a timely and effective manner and will accumulate in large quantities, causing pollution to the environment.

[0004] Fly ash is fine particles that are collected and discharged from the flue gas duct after coal powder or coal sludge is burned at high temperature in the furnace. Although the annual utilization rate of fly ash in my country has reached more than 70%, the stockpile of fly ash is still large due to long-term accumulation.

[0005] Ceramic granules are approximately round ceramic particles with excellent properties such as hard shell and low density. Therefore, they are widely used in building materials, horticulture, chemical industry and other fields. Using solid waste as raw material to produce ceramsite not only alleviates the current situation of large-scale accumulation of solid waste, but also makes solid waste resource utilization. The existing ceramsite production system mostly uses one type of solid waste, with low resource utilization efficiency, and needs to be roasted at high temperature in a kiln, which consumes a lot of energy.
