Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
As shown in fig. 1;
A smoke recirculating fan comprises a base 1, a bearing seat 4 arranged on the upper surface of the base 1 and a fan shell 3 fixedly connected to the right surface of the base 1.
In this embodiment: since the boiler flue gas recirculation fan is used, flue gas enters into a bearing box along a fan shaft, and the flue gas is condensed into water to be mixed with lubricating oil, so that the oil emulsion is replaced, the bearing is damaged, the oil replacement of the flue gas recirculation fan and the bearing are normal, a large amount of labor is wasted, and the running cost of the boiler is increased.
Further, the method comprises the following steps:
as shown in fig. 1 to 3:
in combination with the above: the inside of bearing frame 4 is inserted and is equipped with fan axle 6, and the one end of fan axle 6 extends to the inside of fan shell 3 to rotate with fan shell 3 and be connected, the surface cover of fan axle 6 is equipped with circular baffle 2, and circular baffle 2 is located the inside of fan shell 3.
In this embodiment: the inner hole of the circular baffle plate 2 is assembled on the fan shaft 6 in an interference manner, the outer diameter of the circular baffle plate 2 is larger than a bearing cover in the bearing seat 4, and smoke is discharged from the fan shell 3, so that the smoke does not have a gap due to the interference fit between the circular baffle plate 2 and the fan shaft 6, and can diffuse into the bearing seat 4 along the circumferential direction of the circular baffle plate 2, so that the oil in the bearing seat 4 is not emulsified any more, and the bearing is damaged.
It should be noted that: the arrangement of the circular baffle plate 2 avoids the problem that the bearing is damaged due to the fact that smoke enters the bearing seat 4 along the fan shaft 6 and is condensed into water when meeting cold and is mixed with lubricating oil.
Still further, the method comprises:
in an alternative embodiment, the fan 5 is sleeved on the surface of the fan shaft 6, the fan shaft 6 is fixedly connected with the fan 5, the fan 5 is located in the fan housing 3, and the fan 5 is fixedly connected with the circular baffle 2.
In this embodiment: the operation of motor drives the belt pulley and rotates, and the rotation of belt pulley drives the belt pulley that is connected with fan axle 6 through the belt and rotates to drive fan axle 6 and rotate, the rotation of fan axle 6 drives circular baffle 2 and flabellum 5 synchronous rotation, and the rotation of flabellum 5 can make the flue gas flow, and the setting of circular baffle 2 has avoided the flue gas to enter into bearing frame 4 along fan axle 6 the flue gas and has met the problem that cold condensation water and lubricating oil mixed and cause the bearing damage, thereby prolongs the life of this flue gas recirculation fan.
Still further, the method comprises:
In an alternative embodiment, the circular baffle 2 is internally provided with an inner bore, and the circular baffle 2 is connected by interference fit with the inner bore and the fan shaft 6.
