Description
Technical Field
The utility model relates to a selection powder machine guide vane welding set belongs to selection powder machine guide vane preparation technical field.
Background
Currently, the grinding technology is widely applied to grinding raw materials and clinkers in the cement industry, grinding raw coal with various qualities in the electric power and coal chemical industry, grinding blast furnace slag and steel slag in iron and steel plants, and the like. The grinding and powder selection are two very important process flows in the whole grinding process system, and the powder selection technology is an important factor which directly influences the efficiency of the whole grinding system and the quality of a final product. A vertical grinding cage type powder concentrator belongs to the third generation powder concentrator. The main characteristic is that a cage-shaped rotor with adjustable speed is arranged in the rotor, and a circle of guide blades is arranged on the outer ring of the rotor. Fine powder ground by a grinding disc and a grinding roller enters a powder concentrator under the action of high-speed hot air, and particle flow is firstly subjected to gravity classification (the region is an auxiliary classification region) in a complex annular region formed by a powder concentrator guide blade, a powder concentrator shell, a coarse material collecting cone and a grinding body; then the coarse particles enter a concentric annular region formed by the outer edge of the rotor blade and the inner edge of the guide blade to be centrifugally classified (the region is a main classification region), the coarse particles are centrifugally thrown out of the annular region by the cage-shaped rotor in the region, and slide to a grinding disc along the inner side of the guide blade to be ground again, and the finished product particles are discharged out of the mill through the rotor and enter a finished product warehouse through dust collection equipment and conveying equipment.
In the process, rotor blades are continuously washed and worn by finished materials, the severely damaged rotor blades can influence the yield of the powder concentrator, guide blades of the powder concentrator are usually arc-shaped composite wear-resistant alloy plates and consist of a low-carbon steel plate and a wear-resistant alloy layer, and the thickness of the wear-resistant alloy layer is 3-4 mm generally. The guide vane of the traditional powder concentrator is manufactured by mechanically bending a planar composite wear-resistant alloy plate, the composite wear-resistant alloy plate has the characteristics of high hardness and excellent wear resistance, the plasticity is poor, and when the diameter of a bending roll is less than 300mm, the wear-resistant layer of the composite wear-resistant alloy plate is easy to crack and peel seriously. Powder concentrator guide vane is rolling up the low carbon steel plate face through machinery, the wear-resisting aspect can produce anomalous crack in the arc region, crack maximum width exceeds 1 millimeter, at the powder selection in-process, the crack region is washed away wearing and tearing by the material, make compound wear-resisting layer gold plate base plate wear-out under the serious condition, destroy rotor dynamic balance, cause the powder selection efficiency not high or the powder selection inefficacy, lead to whole grinding system inefficiency, greatly increased system energy consumption, so need one kind can bend earlier then carry out welded device to the steel sheet.
