Slag dryer steel belt, Stainless steel conveyor belt, transmission steel belt, dry slag conveyor belt:
Technical requirements: stainless steel wire mesh with diameter Φ4 / Φ5 mm, double-stranded, steel plate is produced by embossing, heat resistance above 800℃, time guarantee value not less than 50,000 h, appearance quality of steel strip: steel strip and sinking There should be no obvious dents in the bend of the surface of the string. Ensure the welding quality of the net and string, when the short-term or long-term high temperature strength of the joint is not less than the corresponding value of the base metal, and the surface of the welded part is smooth, the stainless steel conveyor of the straight section is flat, and the flatness error is 0.8 mm or less ; The height of the stamping surface is the same, and the error is 0.5 mm or less; the bearing steel is reliably overlapped, and there is no dust leakage in time. The height of the two wing steel plates is the same, and there is no warpage. After assembly, the plane of the suspension board is horizontal, and the height error is 1 mm or less. After assembly, the side of the suspension board maintains a straight line, and the error is within 1mm.
The mesh belt is connected to the steel plate with heat-resistant stainless steel screws, and the connection plate. The depth of the sink hole should be the same to ensure that the screw is on the flat surface and the flat surface on the motherboard. Fixing bolts. After each screw fixes the plate, spot welding with a stainless steel conveyor. There must be at least two welding points between the mesh belt and the steel. The surface must be treated, the surface must be clean, oil-free, and the brightness must be consistent.
Dry slag machine steel belt, dry slag conveyor:
Under normal boiler operating conditions, the hot slag (about 850°C) leaking from the bottom ash hopper will be discharged from the bottom ash discharge device to the steel belt of the steel belt conveyor and move slowly with the belt. Due to the negative pressure of the boiler, cold air will flow into the casing of the conveyor through the vents to cool the hot bottom ash on the belt and make it gradually reburn, thereby realizing the heat exchange between coal air and coal. The hot bottom ash, and then the cold air absorbs the sensible heat of the ash and the heat released by the reburning ash, before entering the boiler furnace, the air temperature will rise to 400-500°C. The bottom ash will be conveyed on the slag conveyor through a steel belt and cooled to below 200°C, and then conveyed to the subsequent conveying device.
