Abstract
The utility model provides a furnace platform circulating fan of a bell-type furnace, which shortens the distance between a shaft head of a motor shaft and the outer wall of a gland of a water cooling box to 415 and 420 mm; and meanwhile, a water cooling box gland is arranged on the outer side of the motor bearing box of the circulating fan, a radiating fin is arranged at the bottom of the water cooling box gland, a water inlet hole and a water outlet hole are formed in the wall of the motor bearing box, and the water inlet hole is respectively communicated with the water cooling box gland and a cooling water pipeline. Because the water-cooling box type gland with the radiating fins is adopted, the effect of increasing the Nm by more than 10Nm is realized3The flow of the/h is used for supplementing circulating cooling water into the water-cooling box type gland, so that the bending of a motor shaft can be avoided, the vibration of a fan is reduced, the heat dissipation condition of the motor can be effectively improved, the temperature of the motor is reduced, the service life of the motor is prolonged, and the normal production of the bell-type furnace is ensured.
Description
Technical field
The utility model belongs to machinery field, relates in particular to a kind of circulating fan for prevention bell-type furnace coil base.
Background technique
The motor shaft of certain cold rolling mill bell-type furnace circulating fan is directly connected with impeller, prevention bell-type furnace coil base working environment is very harsh, when bell-type furnace is normally produced, in stove, be perhydro gas, operating temperature is at 760 ° more than C, impeller is under furnace high-temperature state, revolution requires to reach more than 2000 revs/min, causes motor shaft often crooked, fan vibration, not only affect bell-type furnace and produce, and draught fan impeller vibration is very easy to occur hydrogen explosion accident.In order to reduce, because the crooked vibration producing of motor shaft has been taked to shorten the measure of motor shaft length, yet shortened because of motor shaft, the problem of bringing is that motor is near apart from stove high-temperature zone, directly affects lubrication effect and the working life of motor.
Summary of the invention
It is crooked that the utility model aims to provide a kind of motor shaft of can avoiding, and reduces fan vibration, can guarantee motor radiating again, extends the motor prevention bell-type furnace coil base circulating fan in working life.
For this reason, the solution that the utility model is taked is:
A kind of prevention bell-type furnace coil base circulating fan, comprise motor shaft and motor bearings case, it is characterized in that, in circulating fan motor bearings case outside, water cooling box gland is installed, water cooling box gland bottom is provided with radiating fin, in motor bearings case tank wall, have water inlet and osculum, water inlet interlinks with water cooling box gland and cooling water pipeline respectively.
Described motor shaft spindle nose is 415-420mm apart from the length of water cooling box gland outer wall.
The beneficial effects of the utility model are:
Owing to having adopted, be with the box gland of gelled water-cooled, realized being greater than 10Nm
3the flow of/h, to replenishment cycles cooling water in the box gland of water-cooled, not only can avoid motor shaft crooked, reduces fan vibration, and can effectively improve motor radiating condition, reduces motor temperature, extends motor working life, guarantees the normal production of bell-type furnace.
Accompanying drawing explanation
Fig. 1 is circulating fan partial sectional view.
In figure: motor shaft 1, radiating fin 2, water cooling box gland 3, motor bearings case 4, water inlet 5.
Embodiment
As seen from Figure 1, the left end of circulating fan is provided with the motor shaft 1 being connected with impeller, in the inboard of motor shaft 1, motor bearings case 4 is housed, and motor bearings case 4 is inlaid with bearing.The utility model one is the extrusion that has shortened motor shaft 1, by motor shaft 1 spindle nose, apart from the shorten length of water cooling box gland outer wall, is 419mm.The 2nd, the water cooling box gland 3 of hollow has been installed in the outside of circulating fan motor bearings case 4, in the bottom of water cooling box gland 3, spaced set has radiating fin 2.Meanwhile, in motor bearings case 4 tank walls, be processed with water inlet 5 and osculum, water inlet 5 interlinks with water cooling box gland 3, and connects cooling water pipeline by connecting tube, to be greater than 10Nm
3the flow of/h is to the interior supply recirculated cooling water of the box gland 3 of water-cooled.
Claims (2)
1. a prevention bell-type furnace coil base circulating fan, comprise motor shaft and motor bearings case, it is characterized in that, in circulating fan motor bearings case outside, water cooling box gland is installed, water cooling box gland bottom is provided with radiating fin, in motor bearings case tank wall, have water inlet and osculum, water inlet interlinks with water cooling box gland and cooling water pipeline respectively.
2. prevention bell-type furnace coil base circulating fan according to claim 1, is characterized in that, described motor shaft spindle nose is 415-420mm apart from the length of water cooling box gland outer wall.
