The utility model belongs to the technical field of the engineering material transportation and specifically relates to a wear-resisting stifled device that prevents that is used for cement kiln mixing bunker.
Background
The trend of cement kiln raw material treatment is to pre-blend limestone and clay and then convey the pre-blended limestone and clay to a pre-homogenization storage yard. The limestone and clay mixture after pre-homogenization treatment is conveyed to a mixing bunker of a batching station, enters the bunker from the top of the bunker and is discharged from the bottom of the bunker, so that the purposes of storage, homogenization and quantitative feeding are achieved. The size of the limestone-clay mixture is usually 0-75 mm. Most of limestone is massive and seriously smashes and erodes the wall of the mixing silo; the clay has high viscosity and is easy to be adhered on the bin wall to cause material blockage in the bin. Usually, the polymer resin lining plate with a smooth surface is paved in the mixing bin to prevent material blockage. However, under the smashing and washing of limestone, the polymer resin lining plate is easy to wear and fall off, the inner wall of the bin is uneven, and the material is more easily stuck to cause the blocking in the bin. Particularly in rainy areas, the material moisture is high, the material blockage of the mixing bin is very easy, the workload of manual blockage removal is very large, and even the continuous operation of a cement production line is influenced.
