Abstract
The utility model relates to a fan for heating furnace, which comprises an electric motor (9), a draft fan base (3), a transmission shaft (2) and a fan blade (1), wherein the transmission shaft (2) is arranged inside the draft fan base (3), the fan blade (1) is connected with the lower part of the transmission shaft (2),and the electric motor (9) shaft is connected with the upper part of the transmission shaft (2). The utility model is characterized in that the transmission shaft (2) in draft fan base (3) is connected with cooling small fan blade component (11). The utility model can effectively prevent the ash content and heat in the furnace from immersing in the bearings and electric motor.
Description
Technical field:
The utility model relates to a kind of blower fan, especially relates to a kind of aluminum alloy bar oven blower fan.Be installed on aluminum alloy bar heating-furnace top.
Background technique:
Aluminium alloy building-material, section bar is present building, decorate the hot-sale products of industry, aluminum alloy hot shears stove is to produce aluminium alloy building-material, the equipment of section bar heating usefulness, be used for heating raw materials aluminum alloy bar, for making the temperature in the oven reach uniformity, avoid heated aluminum alloy bar local heating deficiency, and the situation that causes burning may be concentrated owing to thermal source in some areas, usually at aluminum alloy bar oven top blower fan is set, the application specific standard temperature adjustment fan blade of blower fan is inserted in the burner hearth, drive the fan blade rotation by fan motor, and make temperature equalization in the stove.
Because temperature is very high in the heating-furnace, in the heated process of bar, the stove heat passes to blower fan transmission shaft upper bearing (metal) and top motor by the form of conduction and convection current from the axis hole that inserts fan blade, simultaneously, the ash content that floats in the stove also can fly out with hot air flow in this hole, sticks on the bearing, causes bearing even motor often to damage owing to overheated, ash grade influence, and cause the oven frequent shutdown maintenance of having to, having a strong impact on normally carrying out of producing.
Immerse the damage that causes bearing for avoiding ash content and heat to mix, blower fan system is selected expensive protection bearing usually for use, but effect is still undesirable.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of in-furnace dust branch and heat of stoping to mix the oven blower fan that immerses bearing and motor.
The purpose of this utility model is achieved in that a kind of aluminium oven blower fan, comprise: motor, blower fan seat, transmission shaft and fan blade, transmission shaft is placed through in the blower fan seat, fan blade is connected with the transmission shaft lower end, motor shaft is connected with the transmission shaft upper end, it is characterized in that: be socketed with the little fan blade assembly of cooling on the transmission shaft in the described blower fan seat.
The utility model oven blower fan, the little fan blade assembly of described cooling comprise little fan blade cover and little fan blade, and little fan blade is evenly distributed in little fan blade and puts, and little fan blade cover is socketed on the transmission shaft 2.
The utility model oven blower fan, described transmission shaft is outside equipped with the cooling spacer, and cooling spacer lower end links to each other with blower fan seat upper end, and the upper end connects successively and connects cover, motor seat board and motor.
Motor drives the transmission shaft rotation by coupling, the little fan blade that is fixed on the little fan blade assembly of cooling on the transmission shaft rotates with transmission shaft, stove Internal standard temperature adjustment fan blade plays the effect of mixing well temperature in the stove, when rotating, little fan blade sends certain blast downwards, stop leaking of interior hot air of stove and ash content effectively, the heat of pouring into bearing and motor is effectively controlled; Simultaneously, the cooling water of cooling in the spacer further reduces by transmission shaft and conducts the heat that in the stove, further reduce bearing and around the temperature of member.Revolve by reality, the rapid wear bearing of blower fan system and the life-span of motor are greatly improved through last measure.
