Abstract
The utility model discloses a high-temperature smoke exhausting centrifugal fan special for nuclear power. Existing centrifugal fans cannot meet the fan performance requirements supporting nuclear power ventilation engineering and adapt to special operating environments such as high-temperature continuous operation. The technical scheme of the high-temperature smoke exhausting centrifugal fan special for nuclear power is characterized in that an air inlet is formed in one end surface of a machine casing, an air outlet is formed in the other end surface of the machine casing, the end surface of the air inlet of the machine casing is provided with a flow collector; a main shaft is provided with an aluminum wind cooling turbine which is close to the bearing end of the fan; a motor is arranged outside the machine casing and connected with the main shaft through a belt. According to the high-temperature smoke exhausting centrifugal fan special for nuclear power, the main shaft rotates to drive the wind cooling turbine to effectively dissipate heat on the main shaft, so that the high-temperature-resisting capacity of the fan is improved.
Description
Technical field
The utility model relates to the nuclear power engineering apparatus field, specifically a kind of high-temperature smoke discharging centrifugal blower of the DVF of nuclear power plant system.
Background technique
Along with nuclear power station develops rapidly, the blower fan that uses in the DVF system that matches with it needs 400 ℃ of high temperature to move continuously, and general centrifugal fan structure, performance are difficult to meet DVF system and Environmental Conditions demand.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect that above-mentioned prior art exists, and a kind of rational in infrastructure, smoke evacuation centrifugal blower of meeting high temperature resistant requirement is provided.
For this reason, the utility model adopts following technological scheme: a kind of nuclear power special-purpose high temperature smoke evacuation centrifugal blower, comprise casing, impeller is housed in casing, impeller consists of shroud, hub disk, blade and the axle sleeve that is used for impeller is arranged on blower fan main shaft, it is characterized in that, an end face of described casing forms an intake grill, other end forms an exhaust outlet, on the intake grill end face of casing, slip ring is housed; Described main shaft is provided with air-cooled wheel of aluminium matter near the fan shaft socket end; Casing is provided with motor outward, and motor is connected with main shaft by belt.By air-cooled take turns the rotation heat on main shaft is effectively distributed, improved the heat-resisting ability of blower fan.
Further, on described motor output shaft, drive pulley is housed, on described main shaft, driven pulley is housed, described belt is connected drive pulley with driven pulley, by the driven by motor wheel rotation.
Further, belt is provided with belt hood outward, for the protection of belt.
Further, main shaft is provided with spindle protection cover outward, is used for safety protection.
Further, it is lamellar that described blade shape is palintrope, and the vane curvature radius is large, and lifting surface area increases, and the non-deformability after material is heated strengthens.
The utility model is optimized design to the structure of impeller, and the aeroperformance of impeller better meets performance requirement, than the normal temperature centrifugal blower of industry standard, moves more reliable in hot environment; Rotarily drive air-cooled the wheel by main shaft, heat on main shaft is effectively distributed, improve the heat-resisting ability of blower fan; Casing can choose at random the exhaust outlet direction according to on-the-spot installation requirement, the needs that facilitated site operation to be connected with pipeline.
