The utility model relates to a device which can avoid the blockage of the ball feed inlet and belongs to the technical field of ball mill equipment, which is used to avoid the blockage of the ball feed inlet in the grinding process of raw coal. The technical scheme is that the screw reamer is composed of a spiral reamer, and the screw reamer is installed in the cylinder of the ball milling inlet, and the outer edge of the screw reamer is connected with the inner wall of the cylinder of the ball milling inlet. The utility model increases the spiral reamer in ball milling into the cylinder outlet, when the ball fell into the opening of the inner cylinder milling material will follow the spiral reamer back inside the mill, to avoid the ball blocking phenomenon; the spiral reamer also effectively increased the input of raw coal, and can prevent the coal too wet and by ball milling feed the mouth, thus improving the coal yield, milling production capacity is greatly increased, reaching 2.8t/h. The utility model has the advantages of safety, high efficiency and reliability, reduces the quality standard of raw coal for making pulverized coal, saves the cost, and has good economic benefit.
【技术实现步骤摘要】
一种可以避免球磨入料口堵塞的装置
本技术涉及一种在原煤研磨过程中避免球磨入料口堵塞的装置,属于球磨设备
技术介绍
在矿粉生产过程中,煤粉的质量好坏直接影响热风炉的燃烧效果,从而影响到矿粉产量的高低,质量的好坏。在球磨运行时,球磨里的铁球在磨机里面随着设备的运转做不规则的运动,因此里面的铁球有时会顺着入料口转出来,积累久了就会把入料口堵住,既影响磨内通风,又影响入口下料,进而影响了煤粉的质量和产量。目前球磨入料口存在的另一个问题是,由于球磨入料口的原煤通过速度有限,因此当原煤入料量超出2t/h时球磨下料口就很容易发生堵塞,这就限制了煤粉产量的提高。此外,原煤的干湿不一样,因此它的下料情况也不稳定,尤其是原煤比较湿的情况下,球磨入料口比较容易堵塞。一旦由于上述各种原因造成球磨入料口堵塞就必须停机处理,因此影响了生产的正常进行。堵塞发生后,球磨入料口清理困难,需要拆除管道,清理后再装上,既费时又费力。清理工作造成设备频繁开停车,每次停车不仅影响产品品质,而且会对设备造成不良后果,影响使用寿命,增大了生产成本。基于此,非常有必要对现有的球磨入料口进行改进。技术内 ...
