Abstract
The utility model discloses an induced draft fan for a kiln. The induced draft fan for the kiln comprises a cylinder-shaped outer shell, an axial flow type fan is arranged inside the outer shell, the fan is fixed on a shaft seat through a main shaft, the shaft seat is fixed on the axis of the shell through a shaft seat frame on the inner wall of the shell, a driving motor is arranged on the outside of the shell which is provided with a belt hole, and a transmission belt is connected with a driving motor belt wheel and a fan belt wheel at the lower end of the main shaft through the belt hole. A belt protection plate is arrange on the air inlet side of the belt, a main shaft protection sleeve is arranged between the shaft seat and the shell, and a cone-shaped fireproofing cap which is arranged on the air inlet side of the belt wheel is welded on the end portion of the main shaft protection sleeve. The induced draft fan for the kiln is simple in structure, strong in high-temperature resistance ability, stable and reliable to operate, and long in service life.
Description
Technical field
The utility model relates to a kind of blower fan, especially a kind of kiln axle induced-draft fan.
Background technique
Brickkiln needs with induced draught fan high-temperature flue gas to be discharged in the process of producing, because the working medium of this induced draught fan is high-temperature flue gas, this high-temperature flue gas has the temperature height, it is many to contain particulate matter, the characteristics such as corrosivity is strong, owing to still be not specifically designed to the Special draft fan of the high-temperature flue gas ejectment in the brickkiln in the prior art, manufacturing enterprise adopts common axial fan as the kiln induced draught fan, therefore, the bearing of this blower fan, lubrication failure occurs in motors etc. easily under the effect of high-temperature flue gas, the faults such as belt is aging, shorten the working life of blower fan, increase the operation and maintenance cost.
The model utility content
The technical problem that model utility will solve: a kind of kiln induced draught fan is provided, and this kiln is simple in structure with induced draught fan, and heat-resisting ability is strong, and blower fan work is reliable and stable, long service life.
The technological scheme that the technical solution problem is taked: a kind of kiln induced draught fan, comprise cylindrical housing, be provided with axial flow fan in the shell, fan is fixed on the axle bed by main shaft, axle bed is fixed on the axis of housing by the axle bed frame on the inner walls, is provided with drive motor in outside, has punch holes at housing, drivign belt is provided with the belt backplate by the fan pulley of punch holes connection drive motor belt pulley and main shaft lower end in the inlet side of belt.
As improvement of the present utility model: between axle bed and housing, be provided with main axis protective sleeve.
As further improvement of the utility model: be provided with the taper Flue isolation in the inlet side of belt pulley, the taper Flue isolation is welded in the main axis protective sleeve end.
Beneficial effect: kiln of the present utility model with induced draught fan owing to adopted described kiln to comprise cylindrical housing with induced draught fan, be provided with axial flow fan in the shell, fan is fixed on the axle bed by main shaft, axle bed is fixed on the axis of housing by the axle bed frame on the inner walls, be provided with drive motor in outside, have punch holes at housing, drivign belt connects the fan pulley of drive motor belt pulley and main shaft lower end by punch holes, be provided with the technological scheme of belt backplate in the inlet side of belt, motor is arranged on the outside of housing, avoided high-temperature flue gas directly to wash away motor, motor is caused damage, improved the working environment of motor, prolonged the working life of motor, and prevent that by the belt protection plate high-temperature flue gas from directly washing away belt, make belt aging, also prolonged the replacement cycle of belt, make blower fan work more reliable and more stable, simultaneously, reduced the day-to-day operation maintenance cost of blower fan; Owing to adopted the technical characteristics that between axle bed and housing, is provided with main axis protective sleeve, main shaft is not directly contacted with high-temperature flue gas, effectively protected the lubrication effect of main shaft, reduce the running resistance of blower fan, prolonged the working life of blower fan; Owing to adopted in the inlet side of belt pulley and be provided with the taper Flue isolation; the taper Flue isolation is welded in the technical characteristics of main main protection cover end; make the high-temperature flue gas that enters blower fan under the guide functions of taper Flue isolation, flow to rapidly the fan blade face; after obtaining kinetic energy, fan discharges fast blower fan; further avoided main shaft to be subjected to the erosion of high-temperature flue gas; also reduce the working resistance of blower fan, improved the working efficiency of blower fan.
Description of drawings
