Technical Field

The utility model relates to the aspect of production of gangue ceramsite. More particularly, the utility model relates to a pressed rail ring type gangue decarburizing machine.

The gangue is solid waste discharged in the coal mining process and the coal washing process, and is a black gray rock which has lower carbon content and is harder than coal and is associated with a coal bed in the coal forming process. The coal gangue yield accounts for about 18% of the coal yield, and China is the country with the largest coal gangue yield in the world. The generation of coal gangue is up to 6.5 hundred million tons each year, the storage of coal gangue in China is up to 100 hundred million tons at present, and the occupied area is 2 ten thousand mu. While occupying a large amount of land, sulfide contained in the gangue has destructive effects on soil, water resources, ecological environment and physical health of people after being dispersed. Therefore, changing the coal gangue into valuable is of great importance.

The demand of cement or building field for cement lightweight aggregate is large, and a large amount of gangue can be consumed. However, these two fields have high requirements for lightweight aggregate index. Residual carbon and sulfur contained in the gangue have adverse effects on the strength, density and water absorption of the lightweight aggregate, and the gangue needs to be decarburized to obtain the material with the required physical and chemical properties. The coal gangue can meet the requirements only by complex processing, but the coal gangue has low profit, so that the market power is insufficient, the cost is reduced, the yield is improved, the market power of the coal gangue product is improved, the key for solving the environmental problem is also realized, and besides the cost is reduced by a process means, the investment cost of equipment is also extremely important.

The equipment for decarbonizing the gangue in China comprises a sintering machine, a rotary kiln and a belt type roasting machine, the sealing performance of the sintering machine and the rotary kiln is poor, gas is generated in the lightweight aggregate in the sintering process, the internal stress is increased, and therefore the coal gangue is cracked and pulverized, and the yield is low. Poor product quality, low uniformity and incapability of large-scale production; the belt roasting machine can realize large-scale production, the product quality can be ensured, but the belt roasting machine is linear equipment, the equipment investment cost is huge, the occupied area is large, the feeding and discharging distances are far, the operation cost is increased, the trolley utilization rate is low and only reaches 40% of the total trolley quantity, the heat loss is large, and the economic benefit is hardly generated.
