Still including the cooling body, the cooling body includes water pump, this water pump and motor output shaft, the alignment of shafts prolongs the axial and opens and to have a cooling water hole, pipe is led to to cooling water hole one end and the water pump is connected, and the water pump leads to pipe and the water source is connected, the cooling water hole other end is equipped with the drain pipe, and drain pipe and water drainage tank connect. The utility model discloses solve traditional air -blower effectively and because of main shaft cooling effect differs from the lower problem of rotational speed that leads to, improved the output wind pressure of air -blower greatly, improved the working property of air -blower.
Description
Technical field
This utility model belongs to blower technology field, especially relates to a kind of high temperature resistant boiler blower.
Background technology
Existing general aerator, by the wheel rotation in driven by motor bellows, by the rotation of impeller to periphery air blast, and forms vacuum in bellows, and extraneous air then flows into bellows from the space, middle part of bellows.In order to increase blast, then must increase the rotating speed of impeller, and the increase of wheel speed, the pivoting friction between impeller axle and the bearing supporting this impeller axle certainly will be caused to increase, causing bearing heating severe and be easily damaged, this certainly will need the blast selecting resistant to elevated temperatures bearing could improve aerator, and this is very non-remunerative on cost, for above-mentioned reasons, the blast making general aerator is less.Further, when what aerator drum sent is hot blast, the temperature being also easily caused also wheel shaft raises, and is transferred to bearing, makes bearing temperature increase and impaired.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art part, and provides a kind of high temperature resistant and that discharge pressure of fan is bigger boiler blower.
The purpose of this utility model is solved by following technical proposal:
A kind of high temperature resistant boiler blower, it is characterised in that: including bellows, be provided with main shaft in bellows, main shaft is provided with impeller, and bellows are outside equipped with motor, and described motor output shaft is connected with spindle drive by drive mechanism；
Also including cooling body, described cooling body includes water pump, and this water pump is connected with motor output shaft；The described alignment of shafts prolongs and axially has a cooling water hole, and described cooling water hole one end is connected by water pipe and water pump, and water pump is connected by water pipe and water source；The cooling water hole other end is provided with drain pipe, drain pipe and rhone and connects.
Preferably, water source described in the utility model and rhone are same water storage container.
Preferably, cooling water hole central axis described in the utility model and alignment of shafts axis coincide.
Compared to the prior art this utility model has the characteristics that and beneficial effect:
1, offering cooling water hole in impeller spindle, cooling water, by cooling water hole, effectively reduces the temperature of main shaft, can improve the speed of mainshaft, improves the discharge pressure of fan of aerator.
2, water pump and aerator main shaft and same motor connect, and when electric machine main shaft velocity of rotation is very fast, the operating power of water pump is also big, it is ensured that the rate of cooling of main shaft.
3, water source and rhone are same container, repeatable utilization cooling water, reduce the waste of resource.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, this utility model is described in further details.
The high temperature resistant boiler blower of one designed by this utility model, includes bellows 1, is provided with main shaft 2 in bellows 1, and main shaft 2 is provided with impeller 3, and bellows 1 are outside equipped with motor 4, and described motor 4 output shaft is in transmission connection by drive mechanism 5 and main shaft 2.
On the basis of original aerator, this equipment is additionally arranged cooling body, described cooling body includes water pump 6, this water pump 6 is connected with motor 4 output shaft, water pump 6 and aerator main shaft 2 and same motor 4 connect, when main shaft 2 velocity of rotation is very fast, the operating power of water pump 6 is also big, it is ensured that the rate of cooling of main shaft 2.Equally, when main shaft 2 rotating speed is relatively low, the operating power of water pump 6 is relatively low, and decreases the waste of the energy.
Described main shaft 2 center is prolonged and is axially had a cooling water hole 7, and wherein when cooling water hole 7 central axis and main shaft 2 central axis coincide, its cooling effect is best, and the structural strength of main shaft 2 is also best.Described cooling water hole 7 one end is connected by water pipe 8 and water pump 6, and water pump 6 is connected by water pipe 8 and water source.Cooling water hole 7 other end is provided with drain pipe 9, drain pipe 9 and rhone and connects.
When aerator is started working, water pump also starts simultaneously at work, cools down the cooled water hole 7 of current, effectively reduces the temperature of main shaft 2, is guaranteeing that main shaft 2 under the premise of fast cooling, can accelerate main shaft 2 rotating speed, to reach to improve the effect of the discharge pressure of fan of aerator.
Preferably, water source described in the utility model and rhone are same water storage container.Water source and rhone are same container, repeatable utilization cooling water, accomplish saving water resource.
This utility model efficiently solves the conventional fan problem that the rotating speed that causes is relatively low because main shaft cooling-down effect difference, substantially increases the discharge pressure of fan of aerator, improves the service behaviour of aerator.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount the scope that appended claims is defined.
