Abstract
The invention discloses a heat resistant centrifugal fan, adopts wear-resistant and temperature-resistant impellers covered with wear resistant composite steel plates; the impeller is mainly made of WELDOX700E steel; a steel plate dust cover and a double sealing element are arranged on a temperature-resistant bearing; a machine shell is made of Q345C steel; the average thickness of the side wall of the machine shell is 11-16mm; an air inlet and an air outlet are respectively connected with an air inlet box and an air outlet box through flanges; the thermal endurance of the centrifugal fan can be promoted to over 500 DEG C, is suitable for ventilating and discharging dust in hot environment in the industries of steel mills, non-ferrous metal smelting and the like, and has high operation stability, long service life and saved maintenance and updating cost.
Description
Technical field
The present invention relates to centrifugal blower, is a kind of centrifugal blower that can anti-higher working temperature.
Background technique
Centrifugal blower is extensive in sector applications such as power plant, mines, and the pelletizing centrifugal blower moves in the rugged environment of steel mill etc., and the flue-gas temperature height of dispatch causes wind life-span machine to shorten.The high temperature resistant measure of adopting of centrifugal blower both at home and abroad has: the high temperature resistant blower fan of a kind of water-cooled that 1, provides in the granted patent 03254931.8, there is the problem of leaking and corroding in the manufacturing process complexity.2, the high temperature resistant blower fan in the granted patent 00215114.6 has only partly been done heat-resisting processing to impeller, and the miscellaneous part of blower fan is difficult to bear high temperature, and the temperature tolerance of whole blower fan can not significantly improve.3, the high temperature resistant blower fan in granted patent 200620069808.6 is provided with the motor cooling fan blade in rotating shaft, has increased new mechanical component, has increased the difficulty of maintenance, has increased energy consumption.4, iff adopting resistant to elevated temperatures impeller fabrication techniques blower fan, miscellaneous part does not process, and therefore the resistance to heat of whole blower fan also can not improve.
Summary of the invention
Goal of the invention: the heat resistant centrifugal fan that the higher working temperature of the equal ability of a kind of complete machine is provided.
Technological scheme: the present invention is achieved in that and adopts the impeller of a kind of wear-resistant temperature-resistant impeller as this blower fan, the material that is about to component blade, wheel disc or the wheel cap of impeller adopts the WELDOX700E steel, and blade, wheel disc or wheel cover and be coated with Wear-Resistant Compound Steel Plate.Bearing adopts the cylinder or the circular cone ball bearing of heatproof, and bearing has the steel plate dust-proof cover; The material of casing adopts the Q345C steel plate; Air inlet and exhaust outlet adopt the steel plate of thickening to make, and thickness is higher than the average thickness of casing wallboard; The soft connector that the heatproof that is connected with outer pipeline is arranged on the inlet box.
Wear-Resistant Compound Steel Plate can cover the windward side of wheel disc, perhaps only covers on the wheel disc of blades adjacent root of windward side; Wear-Resistant Compound Steel Plate also can cover the intake grill 30-50mm place of leave dual sides, and the blade middle part is near wheel disc side 80-150mm place, blade exhaust outlet end face, the perhaps side of blade exhaust outlet.
Bearing connects the Lubricating-oil Station cooling, not fragile bearing part function when the heat in the assurance casing is transmitted to bearing inside.
The thickness of casing wallboard is than the thick 2-3mm of conventional blower fan, and average thickness is 11-16mm, and there is stiffening rib the part.
Among the present invention, the sealing of spindles part adopts elastic seal ring and N
2The double seal measure of sealing gland, the tightness height guarantees that the gas of over-heat inside can not leak out from the main shaft two ends.Among the present invention, air inlet is or/and the internal surface of exhaust outlet also can add the weldering Wear-Resistant Compound Steel Plate.
Among the present invention, welded flange can be distinguished by intake grill and inlet box place, and connects with bolt; Exhaust outlet and air outlet box also can be distinguished welded flange, and connect with bolt.
Among the present invention, the soft connector of the heatproof that inlet box connects is to adopt the teflon of filling the mineral wool steel wire to make.One end of main shaft can connect the slow train motor, and the other end can have the coupling that connects main motor.
Beneficial effect: adopt heat resistant centrifugal fan of the present invention, its wind pushing temperature rises to anti-more than 500 ℃ by anti-300 ℃ of conventional fan, satisfy in the hot environment of smelting industries such as steel mill, non-ferrous metal ventilate, the specific demand of dust discharge, fan operation stability improves, the field of employment is wider, prolong working life, saves maintenance expenses.
The present invention is described further below in conjunction with drawings and Examples.
