Abstract
The utility model relates to an axial ventilation fan used for ventilation, combustion aid and high temperature fume exhaust on kiln tops of roller kilns producing tiles and bricks. The utility model is characterized in that the utility model adopts a two-stage ventilation fan whose bearing cooling mode is air-cooled mode. The two-stage air-cooled axial ventilation fan has convenient management and high wind efficiency. The utility model solves the problems that the existing ventilation fan for roller kilns has large occupation area, complicated operation management and low wind efficiency.
Description
The utility model is a kind of induced draught fan that is used to produce the combustion-supporting discharging high-temperature smoke of annular kiln kiln top air inducing of brick and tile.
The induced draught fan that existing production Kiln with the function of utilizing waste heat is used, it is centrifugal mostly to be the spiral case that is installed in the annular kiln side, and it exists, and volume is big, power consumption is high, the wind effect is low, underground flue long and take the bigger shortcoming of the other production site of kiln.For overcoming above-mentioned shortcoming, recently the existing axial flow water-cooled induced draught fan that is installed in the annular kiln top, but because project organization, it is numerous and diverse still to exist the fan spindle bearing cooling means, effect is bad, moves shortcomings such as injustice is steady, swing is twisted greatly, easy damage during cantilever type single-stage fan work.
The purpose of this utility model provides the air-cooled axial flow annular kiln of a kind of twin-stage induced draught fan, and it has not only cancelled numerous and diverse circulating water cooling device, and has increased one-level air inducing fan, and fan is operated steadily.
The utility model is achieved in that changing single-stage fans air inducing is twin-stage fans air inducing, and fans is installed in the fan shaft two ends respectively, changes the circulating water cooling and be air cooling on the type of cooling of protection fan spindle bearing.
The utility model has reduced taking of production site because the cancellation circulating water cooling device thereby is convenient to operational administrative, while is owing to employing twin-stage fan air inducing, and fan spindle bearing employing Double bearing support, so the fan operation is more steady, blast increases, and the air inducing amount increases.
The concrete structure of model utility is provided by following examples and accompanying drawing thereof.
Fig. 1 is the schematic representation according to the air-cooled axial flow annular kiln of the twin-stage induced draught fan that the utility model proposes.
Fig. 2 is the hollow fan shaft pressure cap of the air-cooled axial flow annular kiln of a twin-stage induced draught fan schematic representation.
Fig. 3 is the hollow fan shaft cut-away view of the air-cooled axial flow annular kiln of twin-stage induced draught fan.
Below in conjunction with detail and the working condition of accompanying drawing detailed description according to the induced draught fan that the utility model proposes.
This induced draught fan comprises motor driving wheel (1), movable triangle line belt (2), induced draught fan follower (3), the hollow fan shaft of induced draught fan (4), upper bearing bracket (5), step (6), first order fan (7), second level fan (8), cold air chamber's hollow support pipe (9), cold air chamber (10), hollow fan shaft vent hole (11), cold air chamber's loam cake vent hole (12), the air inducing Qu Tie (13) on the inwall of hollow fan shaft two ends, pressure cap (14) on the outer wall of hollow fan shaft two ends, wind guiding tube (15).
Twin-stage air inducing fan (7) and (8) is installed in the two ends of the hollow fan shaft of induced draught fan (4) respectively, follower (3) of induced draught fan is installed in the middle of the bearing support (5) of two hollow fan shafts of support induced draught fan (4) and (6), and by movable triangle line belt (2) be installed in wind guiding tube (15) motor outward and obtain power.
It is solid in hollow that air inducing arbor (4) changes tradition, bearing support (5) and (6) are fixed in the cold air chamber (10) that completely cuts off with high-temperature smoke, and cold air chamber (10) is fixed on the wind guiding tube (15) by the supporting frame made from hollow tubular (9), and endoporus one end of each root hollow tubular (9) is communicated with the external world by wind guiding tube (15), the other end communicates with cold air chamber (10) inner chamber.Wai Jie cool air forces to suck cold air chamber under air inducing fan high speed rotating like this, bearing support (5) and (6) interior bearing are carried out air cooling after, part cold wind is entered in the wind guiding tube by the vent hole that covers in the cold air chamber (12).
Lower end at hollow air inducing arbor (4), it is induced draught fan air intake direction, two of welderings and the corresponding to helical air inducing of fan sense of rotation Qu Tie (13) on air inducing arbor (4) inwall, an end of this pressure cap of air inducing arbor (4) outer wall cover two pressure caps (14) fix one cross-shaped and with inwall on the corresponding to induced-draft plate of air inducing Qu Tie (13) sense of rotation.Hollow air inducing arbor (4) has two elongated holes (11) in cold air chamber (10) inner chamber section, when hollow air inducing arbor (4) high speed rotating, at air inducing Qu Tie (13) with have under pressure cap (14) effect of induced-draft plate, the part high-temperature smoke is by discharging wind guiding tube in the hollow air inducing arbor (4), the part cool air in the cold air chamber (10) sucks by elongated hole (11) and discharges wind guiding tube in the hollow air inducing arbor (4) simultaneously.
Owing to having adopted twin-stage air inducing fan, increase the blast in the wind guiding tube, not only improved induced draught fan efficient, also because pressure sucks a large amount of cool airs, thereby guaranteed cooling to bearing, reached the purpose of removing the numerous and diverse device of a cover that is cooled with circulating water.
